Description

Fully assembled housing structure that can withstand high-level earthquakes

technical field

The invention relates to the field of building technology, in particular to a fully assembled building structure that can resist high-level earthquakes.

Background technique

With the development and progress of building technology, more and more modular housing structures are being used. In the case of building modular housing structures, manufacturers first shape various housing components, such as making wall panels, roof panels or The floor, and then transport these house components to the site where the modular house structure needs to be built, and splice and assemble these house components to form a house structure.

In the existing house construction, generally according to the steel bar model corresponding on the design drawing, the raw material is cut and processed and then directly transported to the site, and then the workers use steel wires, tools and binding frames to carry out the construction. Before the concrete pouring construction, irresistible factors such as trampling on beams and slabs for many times, multiple adjustments of formwork, and large impact force of pump pipes during concrete pouring will easily cause large deviation of vertical bars of shear wall columns and easily affect the shear force of the upper floor The location of the studs of the wall columns and the detection of the studs of the later shear wall columns.

In the prior art, the anti-seismic housing is generally realized by pre-embedded anti-shock mechanism. For example, the existing patent (notification number: CN 213477162 U announcement date: 2021.06.18) discloses an anti-seismic house structure that is easy to assemble. It uses the first shock absorbing mechanism and the second shock absorbing mechanism to make the earthquake-proof house structure have a good shock-proof function, but it does not improve the wall panels themselves. The current wall panels are generally made of cement steel bars and are very heavy. , it is easy to cause damage to the shock absorbing mechanism at the bottom when encountering an earthquake. After research, it is found that the weight, bending strength, load-bearing capacity, and hanging capacity of the wall or floor slab will directly affect the seismic effect of the house. In order to resist high-level earthquakes To reduce casualties and property losses caused by earthquakes, it is necessary to design lightweight wall or floor structures, and it is necessary to ensure the bending strength, load-bearing capacity and hanging capacity of the wall or floor structures; due to existing technology needs Set up cement reinforcement to ensure the strength, which makes the construction very difficult and seriously affects the construction period.
