c) After the inspection is finished, the floor can be poured to form an integral floor stress system.
Preferably, the flexible telescopic block is made of a hydrophobic flexible material with A-class or B-class combustion performance (national standard GB 50222-2017).
In the slab joint structure of the light steel joist system,:
the flexible telescopic block plays a vital role in the whole structure, can be used as a side template in the process of pouring a floor slab, can absorb deformation generated by deformation of a floor slab material under the temperature and humidity environment, reduces the influence on the inner partition keel and the sealing plate, and ensures the construction precision of a wall body.
The invention has the beneficial effects that:
in the prior assembled light steel joist system building, common problems in the construction stage are numerous, such as the influence on the wall caused by pouring a floor. However, the most important problems in floor systems often occur in the mishandling of cast-in-place layers.
In the first condition, in order to reduce the usage amount and cost of the mould at the pouring partition wall of the floor slab in the construction process, the floor slab is often fully paved during pouring, the cast-in-situ floor at the inner partition wall is continuously operated, and the upper partition wall keel is installed on the pouring floor, so that the force transmission path of the light steel structure is interrupted, the force transmission of the force-bearing member is blocked, and the structural safety is influenced.
In the second condition, when the floor slab of the light steel joist system building is poured, in order to reduce the use amount of the grinding tool, the time and labor for disassembling and assembling the grinding tool are saved, the floor is directly poured by taking the inner wall joist as a construction side mould, the deformation of the joist caused by the expansion deformation and the material temperature change of the cast-in-situ floor is caused, the positioning offset of the wall body is caused, the flexible structural system is wrapped by the rigid surface layer, and the flexible anti-seismic advantage of the light steel joist building is hindered.
The flexible telescopic block designed according to the invention therefore plays a crucial role in the overall construction.
The flexible telescopic blocks are prefabricated and formed according to design requirements, and in the installation process, the stress continuity of a structural system is ensured, and the direct force transmission of the upper and lower light steel structures is not affected;
after the inner partition wall stress keel is installed, the flexible telescopic blocks are used as prefabricated and formed modularized products, can be directly installed in place without on-site machining, also play a role of a floor slab pouring side template, do not need complicated procedures of formwork supporting and formwork removing, and greatly save labor cost;
in addition, in the process of pouring the floor, the flexible telescopic blocks are used as side templates, and meanwhile, deformation generated by the change of floor materials in the temperature and humidity environment can be absorbed, so that the influence on the inner partition keel and the sealing plate is reduced, and the construction precision of the wall body is ensured.
The flexible telescopic block designed by the invention fills the blank of the treatment of the detail points in the light steel joist system, and perfects the fine installation flow of the whole system; and the flexible telescopic block material is rich, the price is more economic than a template, and the flexible telescopic block material is more suitable for the characteristic advantage of an assembled building, and has great application prospect and objective economic benefit.
