Method for implementing fabricated concrete house building by using members with novel connecting ends

Abstract

The invention relates to a method for implementing fabricated concrete house building by using a member with a novel connecting end, which is characterized in that stress member columns and beams (including a roof truss beam and a stair beam) for fabricated construction have the following common characteristics: the end surfaces of the stress member columns and beams are plates integrally welded with reinforcing bars in the members, a plurality of holes are formed in the plates, and a certain distance is reserved between the plates and concrete on the back surfaces of the plates; therefore, the components can be conveniently connected through high-strength bolts. After the components are mutually connected, concrete can be conveniently poured at the connecting position, the connecting strength of the finished component nodes is not lower than or even higher than the strength of the nodes finished through the technology that the concrete is poured after steel bars are bundled on site, and the frame assembled on site actually becomes a whole. And on-site concrete pouring is only carried out at the joints, and the pouring amount is far smaller than that of traditional concrete construction. Aerated concrete wallboards are adopted in the maintenance system, and it is guaranteed that the building has good heat preservation, sound insulation and heat insulation functions. The method has the beneficial effects that the assembly rate of a concrete assembly type building is greatly improved; the investment of a concrete member factory is reduced; the supply distance of a concrete member factory is expanded; the on-site construction cost is reduced, and the house building quality is improved.

Description

[0001] Technical field [0002] The invention relates to a method of building a house using a prefabricated concrete system. [0003] technical background [0004] The current method of building a house with a prefabricated concrete system has the following deficiencies: [0005] 1. The design and production of components have not yet been standardized, so there are a large number of components; components include various large prefabricated components, not only the cost of mold making is high, resulting in high cost of prefabricated parts, but also the transportation of large prefabricated parts Larger vehicles and some special brackets are required, and the additional transportation costs further increase the cost of building the house; the production of large-scale and various prefabricated reinforced concrete components determines the large investment of the concrete prefabricated component processing plant, which further limits its ubiquity of use. The above reasons cons...

Problems solved by technology

[0005] 1. The design and production of components have not yet been standardized, so there are a large number of components; components include various large prefabricated components, not only the cost of mold making is high, resulting in high cost of prefabricated parts, but also the transportation of large prefabricated parts Larger vehicles and some special brackets are required, and the additional transportation costs further increase the cost of building the house; the production of large-scale and various prefabricated reinforced concrete components determines the large investment of the concrete prefabricated component processing plant, which further limits its ubiquity of use

The above reasons constitute that the construction cost of the concrete prefabricated system is higher than the construction cost of the traditional process. Therefore, it is difficult for the current prefabricated concrete system to be accepted by the market.

[0006] 2. The cast-in-place frame concrete completed by traditional technology is an integral structure, and its stress system is perfect

However, the current prefabricated concrete technology has not yet realized that the assembled frame concrete is a whole, and some important nodes have certain hidden dangers in the structure, and there are still technical defects.
