Description

A kind of modularity low layer assembled Special-Shaped Column steel house system

Technical field

The present invention relates to a kind of modularity low layer assembled opposite sex post steel house system, belong to technical field of structural engineering.

Background technology

China's annual town and country newly constructed house area 2,000,000,000 square metres, wherein more than 80% builds for high energy consumption, China's unit construction area energy consumption It it is more than 2 times of developed country.Joining in a common effort meter according to China's steel, China's output of steel in 2011 breaks through 700,000,000 tons of high pointes, within continuous 16 years, is sure to occupy the world Various countries' output of steel is the first, and developed country's steel building area accounts for overall floorage more than 50%, and Japan accounts for 80%, and China is less than 4%. China is as construction scope in the world, the country of steel yield maximum, and the development of light-duty steel construction house is the most delayed.

Traditional construction is inefficient, and around construction is caused serious environmental pollution, has a strong impact on construction surrounding enviroment and resident living. In work progress, step is various, low degree of specialized division of labor, causes staff easily to go out because of the numerous and diverse various change of job category in work progress Existing mistake usually can slow down and even blocks construction progress speed and then affect speed of application and construction quality.These problems are intense industrializations Assembled architecture innovation is imperative.

A kind of modular assembly formula Special-Shaped Column steel house system is the assembled architecture of a kind of intense industrialization, because it is unified in factory The construction of specification and finishing, it is simple to each of all assembling type steel structure external member modules construction procedure can be carried out by same construction team, So making construction degree of specialization be greatly improved, efficiency of construction and construction quality are greatly improved, with seasonal sudden engineering accident or mistake Probability of happening is greatly reduced by mistake；Because the manufacture of assembling type steel structure module can remove fixing water heating pipeline and assembling type steel structure module in factory It is connected with each other the whole constructions outside parts, and less at the usual house of factory's periphery, significantly reduce the construction shadow to resident living environment Ring, and just can complete to build in the regional installation that only need to carry out intermodule connector of construction and being connected with each other of intermodule pipeline；On-the-spot Quick assembling, on the premise of ensureing construction quality, improves site operation speed, decreases the site operation duration, reduces system engineering and makes Valency and engineering accident or mistake odds；The more important thing is that steel construction inner room module can recycle, owing to intermodule uses bolt even Connect, can split very easily, and transport the place that the next one uses.

Summary of the invention

The present invention proposes a kind of modularity low layer assembled opposite sex post steel house system belonging to technical field of structural engineering.Its purpose exists In in the production and construction of steel structure module, modularity, batch production, standardization and assemblingization are combined, it is achieved that factorial praluction, On-the-spot quick assembling, on the premise of ensureing construction quality, improves speed of application, decreases the construction period, reduce construction costs, and It is capable of recycling.
