Description

Embedded steel structure assembly residential roof panel installation structure

technical field

The utility model relates to a building technology, in particular to a prefabricated building component which can be produced in a factory and assembled on site, in particular to an embedded steel structure assembled residential roof panel installation structure.

Background technique

At present, there are mainly three types of steel structure residential technologies on the market: one is low-rise light steel keel residential technology; the second is medium and high-rise steel structure support system + block wall; the third is medium and high-rise steel structure support system + Lightweight wall panel technology; the first technology is relatively mature, but because the main structure adopts cold-formed thin-walled steel with limited bearing capacity, it is not suitable for multi-storey and high-rise buildings, and it is difficult to promote on a large scale. The second type is far from the concept of building industrialization due to the large amount of on-site masonry work and does not conform to the future development direction. The third technology is still in development and is far from mature, and there are still some technical problems. The biggest problem is that both the inner and outer walls are made of grouted lightweight wallboards, which is easy to cause structural displacement at the connection of the main structure. This phenomenon is particularly prone to occur in some high-rise residential buildings, and this problem is more prominent in some pilot communities that have been built. In addition to the three structures mentioned above, there is also an embedded steel structure assembly building system, which is a green new type of assembly steel structure building system, which is based on the modular "double module" coordination and "module combination" Technology is the main feature of the building and an industrialized building technology system characterized by embedded steel structures and PC panels. This technology runs through the entire process of building (residential) design, processing, installation, equipment installation, decoration, and smart home. , Realize the industrialization, intensification and socialization of the whole process of housing construction, thereby improving the quality and efficiency of construction projects, and realizing energy saving, emission reduction and resource conservation.

The main features of this embedded assembly house are: the building system adopts a dual-modulus coordination mechanism to form modules, which can combine the building planes and building facades of various houses from 80㎡ to 160㎡. As long as the standard board formed by the basic module and some special-shaped boards are added, the plane and elevation dimensions of various living requirements can be met, thereby forming a standardized design and laying the foundation for factory production. The building adopts a steel structure load-bearing system and PC large slab series, laminated floor (roof) panels, EC wall panels, and ALC wall panels to form a complete main structure, which improves the service life and seismic performance of the building. The PC slab adopts an internal insulation structure with concrete on both sides and an insulation layer in the middle, which meets the thermal insulation function and improves the energy-saving effect. At the same time, it meets the requirements of fire prevention and sound insulation. Scaffolding, formwork, plastering and other projects have been basically canceled, beams, columns cast-in-place and steel bar binding and other processes have been cancelled, wet operations on site have been reduced, and the integrated decoration has a flat and smooth surface of the model, eliminating the need for traditional mortar to find Equal process, can directly carry out puttying, whitening and other processes, saving materials. Therefore, the construction period of this prefabricated industrial building is shortened by 2/3 compared with the conventional one, and the labor cost is reduced by 2/3, which ensures safe production and engineering quality. At the same time, the usable area of steel structure residences can be increased by 3% to 5%, and the advantages of energy saving and environmental protection are prominent. After comparative analysis of the cost of the main structure, the cost of the steel structure prefabricated house is basically the same as that of the traditional concrete structure, but its construction period is 1/3 of the traditional one, shortening the investment recovery period, and judging from the current steel market price trend, Traditional labor costs continue to increase, steel prices are falling, and the cost of steel structure housing is expected to further decrease. As one of the key technologies of the embedded steel structure assembly building system, the roof installation technology is very important.

Utility model content
