Modern activities of the Housing Structural Engineering Symposium recently held the 11th,the expert members of the activity room of China Construction Metal Structure Association Building Steel Structure Committee Fanghong Jiang said: “a new type of building system may open up the real estate industryindustry boundaries between the construction industry,metallurgical industry,machinery and equipment manufacturing industry and national strategic resource,a collection of a new industrial system,which is the industry are generally optimistic about the steel building system.”

Fanghong Jiang,steel construction is representative of the green building.The promotion of steel construction development of circular economy is the transformation and upgrading of the traditional civil construction industry.Steel construction not only has a light,fast,good,provincial “outstanding performance,but also has the advantages of recycling.Steel structure with high strength,light weight,good seismic performance,foundation costs province,building area,building high quality,suitable for industrialization and standardization of production of dry-type green construction,suitable for different climatic conditions,from the construction season the impact of comprehensive and low cost,and at the same time,the steel structure can also reduce the pollution of the construction waste on the environment,recycling in the whole life cycle.Fanghong Jiang said that the steel construction in line with the direction of China’s energy conservation and the development of circular economy,the urban environment one of the smallest structure.

Fanghong Jiang introduced the steel structure in developed countries has been widely used,known as the main representative of the Green Building.Europe,said green building for ecological building or sustainable construction.China’s green building in the whole life cycle of the building to maximize conservation of resources (energy,land,water conservation,and materials),protecting the environment and reduce pollution,provide people with health,application and efficient use of space,building in harmony with nature.

Second-hand materials to build the outer Flying Pig

Steel housing stands in the outskirts of Lubbock City,Texas,USA,a small river,the design concept to include environmental elements,seem to look more artistic value.Its peculiar shape,like extraterrestrial spacecraft,some people say like,some people say it resembles a pig,in fact,it comes from the eminent architect and sculptor – the hands of Robert Bruno.Robert Bruno spent a full 23 years,with a total of 110 tons of steel to build a pig-shaped steel construction housing.

Bruno was born in 1945 in Los Angeles,steel housing construction work actually begins 29 years old.After 23 years kept the creative changes and after the unremitting efforts,this unique in the world steel villa is finally completed,and soon to be known as one of the wonders of the construction industry,high-profile.

Originally planned to build only the floor of the house several times to modify and upgrade into a three-story house is now supported by four legs.Constitute the first layer is one of the two legs,they carry out their duties,the family library,indoor elevator and wine cellar.Area of ??20 300 square meters of the upper space is a spiral staircase and Gothic column separated.

Steel housing is unique in that the “four legs” and the cantilever design of the housing construction to minimize the impact of the ground,and ordinary residential design must take into account the face of the building.Steel durable to be recycled,in recent years,often environmental architect used as a roof.The same time,the internal design of this construction steel structure housing materials used,such as metal,wood,glass and mortar,many of which are taken from the old building of the local Texas.Although this is in the practical aspects of life may not be a perfect,but the design idea is very creative,but also extremely environmentally friendly concept.

Kunming building earthquake-proof design scene from the recently held conference, the reporter was informed that in the future, the city government affordable housing projects will first use mitigation and isolation techniques, the government investment projects must use mitigation and isolation techniques, andcivil projects, and actively promote the reduction of seismic isolation technology.
At the meeting, the city’s various functional departments and Kunming to participate in the construction of the new Kunming more than 30 design units, building development companies responsible for the scene to observe the garden construction project of the Yunnan Province and Design Institute of Kwong Fuk County. Mitigation and isolation techniques of tall steel frame structure used by the project, the country is the first case, in areas of high intensity use of the Seismic Isolation Design, will improve the seismic safety of buildings at the same time, greatly reduce the earthquake caused economic losses, increase the use of the building area and effectively clear height. Building the use of advanced mitigation and isolation techniques, but also significantly save the amount of steel, the premise does not affect the structural stiffness, structural beams and columns can be significantly reduced.
The city’s 14 counties (cities) and districts are classified as national and Yunnan earthquake focus surveillance and protection zone, said Chen Yong, vice mayor of the present, in the big plan in Kunming, large-scale development, a large period of construction, the new high-rise buildings increasingly more ultra-high-rise buildings historic breakthrough, building quality and safety is particularly important, the relevant units to the scene to observe, study the seismic resistance of new technologies, new materials in engineering practice, promoting the construction project of the city’s earthquake-proof level, the ability to continuously improve, minimize earthquake damage, change from passive relief for active defense, through the promotion and application of new technology, new materials, further promote the city building energy efficiency, low-carbon economy, green building.
Yong requirements, mitigation and isolation techniques will be the first city government affordable housing projects in the use of mitigation and isolation techniques, the use of government investment projects, and actively promote the reduction of seismic isolation technology in civilian projects. Focus on primary and secondary schools, kindergartens, hospitals and personnel-intensive public buildings earthquake-proof and reasonably determine the seismic standards of the different seismic intensity regional center town.

Planning,pointed to “adapt to the reduction of steel trend,upgrades,hot-rolled steel standard,focus on the development of 400 MPa and high strength twisted steel in reinforced high-strength wire (hard wire);steel steel construction in the construction field,areas of focus on the promotion of high-intensity earthquake,fire and weathering resistant steel plate,and the application of H-shaped steel.”key varieties of steel consumption forecast in 2015 are: high strength reinforced from 56.5 million tons in 2010 to 112 million tons in 2015.
Ministry of Housing and Urban Ministry of Industry in the Year of the Dragon Chinese New Year the occasion of the joint introduction of the “to accelerate the application of high strength reinforced the guidance of views” is also explicitly raised,by the end of 2013,in the construction project eliminated 335Mpa grade steel;the end of 2015,high-strength reinforced the production accounts for 80% of the total output of twisted steel,used in construction works for more than 65% of the total construction with reinforced.
It is understood that,increasingly thin profit pattern of the traditional varieties of steel,2011,Shanghai Bao Xia Wu Mao,Shanghai Hua Lei,the company has gradually withdraw from the competition of steel “Red Sea”,the focus shifted to the seismic reinforcement,high strength reinforced on.Shanghai Hua Leigong Division is to become the Shanghai construction steel circulation has reinforced stock steel trade enterprise.
The domestic steel mills have also joined the ranks of the development and production in reinforced and high-strength steel bars.
China is an earthquake-prone country,typhoons,floods,mudslides and other natural disasters more.Higher requirements in areas such as buildings,bridges,railways,airports,electricity,construction steel,which no doubt provided a broad space for the application of reinforced.
Insiders pointed out,the signs are or revealing a “signal”: the earthquake resistance of reinforced will become a new profit growth point.

Select the customers of this staircase, the general has been laying in the strata of marble, in order to maintain the unity of the interior colors and materials to continue laying marble staircase. But mostly in the choice of the handrail to keep wood products, cold space, add a little warm materials. Apply to the stairs skeleton concrete pouring good staircase grass-roots level, the impression is thick, strong. But for the cost of the entire staircase is still relatively high and the lack of modern flavor.
Finished skeleton and the skeleton of home-made glass, finished skeleton stainless steel or steel chrome-plated as a skeleton, which is a relatively new style, visual effects, delicate texture and rich taste, plus 20mm thick tempered glass, so that the whole staircase showing through Ze clear visual impact is very suitable for the tastes of young people of the modernists. The large glass is tempered float glass, matte can also be used, incomplete transparent, thickness of between 20mm ~ 25mm. Straight ladder or the “L” type ladder can be glass fence (the column of stainless steel or other material), drawing and fencing.
The structure is simple, clean. General self-made steel staircase regardless of appearance or workmanship are difficult to achieve the effect of the finished stairs. Many families in order to reduce the cost, the first angle iron or pipe welding skeleton, and then the board is decorated, but the general effect is not the very best of man, and some Iron production, but the scene of the production process, after all, is difficult to achieve factory mechanization job of processing effect.
-Site processing and finished steel staircase staircase biggest difference in addition to the difference in the quality, the actual outer coating also limits the self-made staircases enhance the quality of field welding of steel stairs, coated with simple polished paint treatment the finished stairs spray treatment, homemade stairs although the price is slightly lower than the finished staircase and finished stairs difficult to have a comparable place.

Policy aiming at underpinning expectations lead to disappointment over

admin — Fri, 03 Feb 2012 05:51:08 +0000

Speaking from the conventional wisdom, the government has been willing to accept the economic slowdown is quite low, the expected stimulus does not seem excessive. Over the years China has not really performed austerity, is basically a case of difficult monetary floodgates to open soon, “growth” is always the most preferred choice.
But this is different. Domestic and international economic situation is too complex and difficult, decision-making until now still not allowed to draw the line, being careful consideration.
From the long term, structural adjustment must continue, otherwise support the rapid growth of Chinese power for 30 years will be unsustainable. This is not to do, but rather how to do, how fast do the problems.
But if we insist on structural adjustment is bound to sacrifice a lot of short-term interests. To real estate, for example, central control has so far not given the ultimate goal is to curb price gains in the end you can, or must be reduced to bit rates have no clear view. In this case, the local government for their own interests, always wanted to walking a fine line, a moment to relax the restriction, while the adjusted target prices and GDP linked. When this situation occurs, the central government but also requires them to stop. But the target is not clear, it means to their aggressive, let others loophole. The results can only be half done, defeated.
Of course, continuing to suppress the real estate market, sellers revenue, related industries such as steel, cement, construction or renovation markets are greatly affected, governments, businesses are suffering, if it is to protect the housing support in force, I am afraid the real estate investment in early on the drain. The resulting slowdown in investment, unemployment and other consequences are difficult to be taken lightly.
But in the past several macro-control, real estate is lost by the wayside, lies can not stand pain. Government is determined to be questioned, interest groups, often threatening, all usher in a new wave of each control more fierce counterattack, the situation becomes increasingly unwieldy.

Tengzhou Housing and Urban Construction Bureau meeting held in the Festival Safety

admin — Tue, 31 Jan 2012 02:33:32 +0000

Festival to do a good job of production safety work, January 30, the city Bureau of Housing and Urban Construction convened by the Housing Authority, Urban Construction Group, urban development, municipal office, China Resources Gas, garden office, Jiefang Road Department and other units of cable-stayed bridge project participate in leadership and Chief of Security in charge of post-holiday safety meeting, current security arrangements for production work.

The construction enterprises set up business after the holiday to return to work safety inspection team, all the requirements of the enterprise under the Ministry of resumption of work items detailed security checks. Construction project the Department of the Ministry to set up a project inspection team return to work after the holiday, the project manager, a full-time security officers, supervisors, is responsible for safety inspections of the project work after the holiday. Projects for the Spring Festival features more than newly recruited staff, the project should be organized to all employees in the Department held a Festival serious safety education for workers to organize a new approach “three safety education” policies preached safety, security operations rules of order, focusing on training of safety rules and regulations, rules to enhance safety awareness and compliance law of consciousness, and resolutely put an end to restore the production process for various types of accidents. While organizational assessment, without passing the examination shall not posts. Return to work after the Spring Festival of the project, the Department must be in strict accordance with the project self-examination, business review, safety supervision and staff supervision procedures. Return to work before the construction project of the Ministry to carry out a project focused security checks, the main contents are: template support system, deep excavation, construction, electricity, heavy machinery, construction site, fire, and large-span steel structure, scaffolding, unloading platform, whether the safety of employees living standards of safety, security risks for the project that the Department of the Ministry of enterprises to track projects supervise rectification in place. Strict accordance with the “check who signed, who is responsible for” principle, and levels of responsibility for security check. To ensure that the return to work after industrial accidents do not occur.
Second, we must grasp Park safety and other public gathering
To tour vehicles, boats, recreational facilities, evacuation routes, fire exits, fire fighting facilities, electrical equipment and wiring and other equipment and aspects of security checks, fail to stop the operation of all safety requirements and use. To strengthen the holidays crowded places for the safety of park management, in particular, to strengthen the hold mass events security management, and prevent crowding, trampling and other casualties. Enhance fire safety management of rental housing.
Third, we must grasp the safety of gas heating
To further improve the rules and regulations, do a good job staff training on safe operation, operation, maintenance, repair, revision operation for full professional training for gas. Accidents found at all levels the timely development of corrective measures, and implement improvement responsibilities and the rectification period, should be reviewed after completion of the rectification to achieve the desired results. Practitioners regularly organize emergency rescue drills. Piped to the station area facilities. Gas pipeline, regulator, tanks, valves, alarms, automatic cut-off device users, connecting pipes, home safety inspection, found hidden immediately ruled out. To enhance the detection of the gas pipeline and supervision, clean the phenomenon of illegal tying, prevent leaks, poisoning and explosion accidents.

Steel structure system with light weight, easy to install, short construction period, seismic performance, quick return on investment, environmental pollution and other comprehensive advantages, the present, steel building is the least impact on the urban environment is one of a structure , has now been widely applied. But steel fram structures are shaped structure, the conventional thermal insulation materials can not be heat insulation, heat loss of a large, energy-saving effect is not good, and prone to condensation phenomena, resulting in corrosion of steel structure and shorten the service life of steel.
Now new thermal insulation material — thermal insulation coatings are plasma body, can be shaped in any construction material, convenient construction, thermal insulation effect. The main raw material is nano-coating hollow beads, Wei Sheng Zhi Hua special high-emulsion, titanium dioxide and other substances, of which the coating of nano-hollow bead content at least 80% or more, after such a paint brush can be formed by the surface beads connected closed three-dimensional network of hollow structures, such as nano-hollow ceramic beads and beads one by one between the static air group stacked folders, that is, one unit of thermal insulation, thermal conductivity of the coating to achieve 0.04W/mK, can effectively prevent heat transfer, excellent thermal insulation, thermal insulation coating level to R-30.1, more than 90% heat reflection, the reflection can be a lot of infrared heat to prevent the infrared objects, can effectively inhibition of the sun and the infrared heat radiation and heat conduction, thermal insulation efficiency of up to 90% inhibition. ZS-211 reflective properties of thermal insulation coatings with high reflectivity and low thermal conductivity, low coefficient of thermal performance of heat storage, is a water-based, high adhesion, long life, thermal insulation, moisture-retardant, fire insulation, no smell, sound environmental protection energy-saving coatings.
