Description

Brick-concrete integrated wall, engineering prefabricated joint method, integrated building construction method

Technical field

The invention relates to the technical field of engineering construction, in particular to the field of integrated building components and construction technology, in particular to a brick-concrete integrated wall body and a connecting member thereof, a method for connecting the same, and a method for forming an integrated building therefrom.

Background technique

Traditional reinforced concrete buildings are filled with concrete at the construction site. Due to the need to maintain the concrete, the construction period is longer. After the prefabricated steel structure is used in the integrated building, it is lifted and installed at the construction site, which can effectively shorten the construction period. However, due to the high requirements of the connection process of the steel structural members, the construction requirements are increased, the difficulty is increased, and the steel structure has the disadvantage of poor fireproof performance. Traditional brick-and-concrete buildings are generally accepted. If the factory can prefabricate all the important components, and the construction site can quickly connect these components, the construction process has a very broad market. In addition, the current simplification of integrated building products is serious, which restricts the development of the industry, and proposes an integrated building model that can achieve free splicing, which is in line with market demand.

Summary of the invention

The object of the invention is to provide a brick-concrete integrated wall which can be quickly installed in a factory production and construction site, and proposes a method for connecting engineering prefabricated parts, which can replace existing welding, riveting or screw connection in certain occasions. The process can be used to integrate building construction technology or other engineering construction fields, and the method is flexible, free and changeable.

The core idea of the technical solution of the present invention is to insert two engineering prefabricated parts by inserting two metal parts (usually steel bars) of the engineering prefabricated parts into the connecting holes, and then pouring the adhesive (in particular, concrete). Specific technical content and benefits include:

1. Design wall bricks with connecting holes. Use steel bars to pass through the connecting holes of the wall bricks. When arranging the bricks, the upper and lower rows of bricks are staggered to enhance the shear resistance of the wall, and then water is poured into the connecting holes. Binder (concrete), to achieve the connection of wall bricks, while maintaining the advantages of brick wall performance, while reducing the cumbersomeness of wall-building action, the factory can be automated by arranging and placing the whole row of bricks; Comparing the wall formed by the prior art document "Construction technology of a concrete hollow block reinforced wall" (CN2013103402115), the method of forming a wall body, the central hole of the upper and lower bricks and the side half hole alternately appear, Neat, beautiful, strong, and easy to flow concrete along the hole (there are gaps in the side half holes), its strict and neat arrangement ensures that it can be factory automated production;

2. On the basis of the prefabricated bottom, there is a specific joint metal part (reinforcing steel), the connecting hole of the wall brick is put into the steel bar, and then the binder (concrete) is poured into the connecting hole, and the concrete and the steel bar are combined to form a row of scattered Small pillars to enhance the load-bearing performance of the wall; and a beam-type main structure that carries the wall bricks, the wall After the body brick is connected to the upper part of the beam body, a detachable brick-concrete integrated wall body is formed; compared with the wall formed by the prior art document "Construction technology of a concrete hollow block reinforced wall" (CN2013103402115), this article The wall described can be hoisted as a whole due to the addition of the bottom foundation;

3, considering the problem of building doors and windows, set the corresponding joint metal parts (rebar) on the prefabricated bottom, and then design the door and window to switch the connecting members, set the connecting holes on the members, and put the connecting holes into the steel bars, use the wall The installation of the upper and lower fixing members of the brick body completes the setting of the door and window; it is also possible to convert the connecting member without adding the door and window, and the wall has a large opening structure, and the edge portion forms a load-bearing column; compared with the existing PC (precast concrete) board, The door and window structure is firstly molded, and the method described in this article retains the free form of the traditional brick wall, and the design of the door and window is easy to implement;

4. Consider connecting the wall in a plane and vertical direction to form a building. When forming the wall, retain the flat and vertical connecting bars, and design standard connecting parts for different connection conditions. The standard connecting piece is a welded metal. Pipe (steel pipe, sometimes steel plate), the steel pipe is put into the connecting steel bar at the construction site, and the concrete is poured, which can realize the connection between multiple walls, thus forming the main body of the building. The construction method is simple and the process precision requirement is relatively low. Compared with the existing steel sleeve grouting connection technology (industry standard "Technical Specification for Reinforced Sleeve Grouting Connection Application" (JGJ355-2015)), this technology first uses the free connection piece, and further utilizes the connecting pipe of the steel bar and the connecting piece. After the connection is integrated, all the connecting pipes are actually an integral frame of the building after being welded and grouted;

5. Standardization of wall size and specification parameters, unified data of building components and database management. According to the basic building plan, the types and quantities of standard building components required can be calculated, and the order can be processed to the factory to realize the management of building process. Scientific and efficient; the content of this article actually needs some software to assist the implementation, but its calculation process is the technical advantage inherent in the invention;

6. Different types of building units can be assembled through standardized walls, so that the integrated building has a user-selectable or even self-designed floor plan, and a business model can be developed. The customer can splicing out different room types according to the existing wall model. It can meet the requirements of customers' self-designed buildings.

Note: This section only provides an outline of the content of the invention. The detailed discussion is found in the specific implementation section.
