Description

A prefabricated housing system

technical field

The invention relates to the technical field of construction engineering structures, in particular to a prefabricated housing system.

Background technique

The prefabricated building structure refers to the standardized production of various components of the structure, including prefabricated columns, prefabricated beams, prefabricated floors, prefabricated shear walls, etc., in the factory, and then the prefabricated components are bolted, welded or prestressed on the construction site. The structure formed by connecting and installing.

The components of the prefabricated building can be industrialized in the factory. The components are equivalent to standard products, and they can be installed directly on site. It can be said that it is convenient and fast. The components are standardized in the factory. On-site production is more guaranteed and can be effectively controlled. The high-standard mechanization of components reduces the number of on-site personnel, which is helpful in terms of labor costs and safe production.

With the rise of my country's prefabricated construction industry and the implementation of the new rural revitalization strategic plan in recent years, strong vitality has been injected into the design of low-rise prefabricated new residential buildings. How to break through the on-site rapid assembly and low-cost The bottleneck of cost construction is a major task of innovative research and development in this field.

Contents of the invention

Aiming at the deficiencies of the prior art, the present invention provides a prefabricated housing system, which is fully assembled, has no wet operation, has high assembly efficiency and low assembly cost.

The present invention is achieved through the following technical solutions:

A prefabricated housing system is provided, which includes a foundation frame connected and fixed by prefabricated beams and prefabricated columns, the foundation frame is connected with a prefabricated foundation at the bottom of the prefabricated columns, the connection node between the prefabricated columns and the prefabricated beams in the foundation frame, and the prefabricated columns and The connection nodes of the prefabricated foundation at the bottom are all anchored and connected by reserved steel bars.

In this scheme, prefabricated beams and prefabricated columns are anchored and fixed by reserved steel bars in the foundation skeleton, and the residential structure is formed by reserved steel bars between prefabricated foundations and prefabricated columns. Compared with traditional concrete connection methods, the assembly is faster and there is no wet operation. Stable structure and cost saving.

The basic frame is also connected to the upper frame, which can realize the construction of three-story and below residential structures. The frames are anchored and connected by reserved steel bars. The structure is stable, there is no wet operation, the assembly efficiency is high, and the assembly cost is low.

Further, the reserved reinforcement includes foundation reinforcement and column reinforcement, the foundation reinforcement is embedded in the prefabricated foundation and protrudes from the surface of the prefabricated foundation, and the column reinforcement is embedded in one end of the prefabricated column and extends out of the prefabricated column along the length direction of the prefabricated column On the surface, the other end of the prefabricated column is reserved with a first grouting channel for the foundation steel bar or column steel bar to penetrate, and the surface of the prefabricated column is provided with a first grouting channel that communicates with the first grouting channel and can be fed with slurry to achieve anchoring. Grouting port, the two ends of the prefabricated beam are reserved at the joints with the prefabricated column for the second grouting channel for the column reinforcement to penetrate and run through the prefabricated beam, and one end of the second grouting channel is for the slurry to pass through To achieve the second grouting port for anchoring, each prefabricated column at one end of its reserved column reinforcement is sequentially penetrated into the second grouting channel on the corresponding prefabricated beam and the first grouting channel of the prefabricated column in the upper skeleton.

One end of the prefabricated column is reserved for the column reinforcement, which is used to connect with the prefabricated beam and the prefabricated column of the upper frame. The grouting port and the second grouting port on the prefabricated beam are injected with grouting material to make it fill the first grouting tunnel and the second grouting tunnel, and the reinforcement anchoring of the skeleton is completed when the grout is solidified.

Further, metal bellows are fixed in the first grouting channel of the prefabricated column and in the second grouting channel of the prefabricated beam.

The metal bellows is fixed with the skeleton steel bars during installation. The fixing method is simple and convenient. The inner and outer walls of the metal bellows have corrugated grooves. After the concrete is poured, the joint surface between the metal bellows and the concrete is firm. Stronger adhesive force can make the connection between the skeletons stronger.

Further, the prefabricated column is a special-shaped column, and the section of the special-shaped column is in-line, T-shaped or L-shaped.

The cross-section of the prefabricated special-shaped column can be well matched with the cross-section of the beam. The end of the beam is in-line, and the flange of the special-shaped column is also in-line, so that the beam can be better lapped on the column to form a more Good connection node.

Further, the cross-section of the prefabricated beam is in a convex shape, and flanges are provided on both sides of the prefabricated beam.

The beam adopts a convex shape, which can be placed on the floor faster when the floor is installed, and the simple connection can meet the requirements, and the construction is fast and convenient.

Further, beam-type floor slabs or prestressed floor slabs are embedded between the corresponding flanges of the adjacent prefabricated beams.

Beam floor slabs should have beams on both sides of the slab, so the slab thickness of the middle slab can be made very thin, and large-span floors can be made. Because the stressed part of the floor slab is at the position of the floor beam, the reinforcement of the slab can be appropriately reduced Dosage. The bottom of the prestressed slab is prestressed steel bars, which greatly reduces the amount of steel bars used to realize large-span buildings.

Beneficial effects of the present invention:

1. It has the advantages of full assembly, no wet operation, fast assembly speed, etc., and the anchor connection is stable and reliable. This structural system is a prefabricated concrete heterogeneous column frame structure, which is suitable for residential villas and other buildings with less than 3 floors.

2. Other parts of the main body are filled with lightweight wall panels, such as foam concrete panels, aerated concrete panels, polystyrene particle concrete panels, etc., and decorative integrated panels are used for thermal insulation and decorative integrated construction. This not only increases the construction speed but also reduces the cost, and is environmentally friendly and pollution-free, reduces construction waste, and also caters to the trend of the construction market.
