CN104328849A - U-shaped rebar inserting connection method of mixed externally hung wallboard and girder - Google Patents

Abstract

The invention relates to a U-shaped rebar inserting connection method of a mixed externally hung wallboard and a girder, and belongs to the field of construction industry. Connection is carried out by adopting connection members, wherein the connection members are composed of steel blocks and rebars; the concrete connection steps of the mixed externally hung wallboard and the girder are as follows: steel blocks with reserved rebar holes are fixed on the edge of the upper end of the inner side of a prefabricated externally hung wallboard; meanwhile, steel blocks with reserved rebar holes also are fixed on the girder; the externally hung wallboard is butted with the position of the girder in connection; the rebars fabricated in advance are inserted into the reserved holes; the externally hung wallboard and the girder are connected well; the juncture of the lower end of the inner side of the prefabricated externally hung wallboard and a floor slab is connected and fixed by virtue of angle iron, so that reliable connection of the prefabricated externally hung wallboard and the prefabricated girder in a plane is achieved. Compared with an existing connection mode, the U-shaped rebar inserting connection method has the advantages that the externally hung wallboard can be separated from an overall frame when seismic action is received, deformation such as free bending and distortion of the frame is not hindered, and the connected U-shaped rebars can play the roles of energy dissipation and energy absorption in the seismic action.

Description

Insertion and connection method of U-shaped steel bars between composite external wall panels and beams

technical field

The present invention relates to a connection method between a building concrete wall and a beam, in particular to a method for inserting and connecting a U-shaped steel bar between a concrete wall panel and a beam, and belongs to the field of construction industry.

Background technique

The prefabricated concrete assembly house is a house in the construction industry that is assembled from light-weight thermal insulation composite wall panels, floor slabs, roof panels, columns and other components that are prefabricated in a factory.

Since Japan put forward the concept of housing industrialization in 1968, prefabricated concrete structure housing has experienced different stages of development, from the initial exploration stage to the gradual formation. So far, the development in North America has been very complete, especially in the United States and Canada, and its relevant precast concrete specifications have basically taken shape. In recent years, the construction technology of prefabricated residential systems in Hong Kong has gradually matured, and mainland my country is still in the process of research and development. In the experimental stage, the development is slow, although there are successful cases, but the number is very small. Prefabricated houses are an effective way to realize the industrialization of houses, and the connection of prefabricated components is one of the key links in this way. Although the houses with mature concrete and steel structures are well fixed and strong, they are still under disaster conditions (such as earthquakes). When receiving the action of transverse wave and longitudinal wave, the entire frame of the wall will be freely bent, twisted and deformed, thus causing damage.

Contents of the invention

In view of the above-mentioned technical problems, the purpose of the present invention is to provide a method for inserting and connecting U-shaped steel bars between the external hanging wall panels and the beams. Finally, the two become a whole with reliable connection.

In order to achieve the above object, the technical solution adopted by the present invention is: the method of inserting and connecting the U-shaped steel bar between the external hanging wallboard and the beam, which is characterized in that the connecting member is used for connecting, and the connecting member is composed of steel block and steel bar; The specific connection steps between the exterior wall panel and the beam are as follows:

Fix the steel block with reserved steel bar holes on the upper edge of the inner side of the prefabricated external wall panel, and at the same time fix the steel block with reserved steel bar holes on the beam. Insert the steel bars into the reserved holes, connect the external wall panels and beams, and connect and fix the junction between the inner lower end of the prefabricated external wall and the floor slab with angle steel.

There are 4 steel blocks, two of which are installed on the beam, and the other two are installed on the inner wall of the external wall panel;

The steel block is a square structure, and several reserved holes are uniformly arranged on the facade of one side of the square;

The distances between the reserved holes are equal;

The right-angle steel is an integral structure perpendicular to the plane and the vertical plane, and a number of through holes are evenly provided on the plane and vertical planes to facilitate the fixing of the connecting piece through the right-angle steel to the ground and the external wallboard.

The reinforcing bars inserted into the reserved holes are of U-shaped structure.

The beneficial effects of the present invention are:

Through the connection method of U-shaped steel bars inserted into the reserved holes, the reliable connection between the prefabricated external wall panels and prefabricated beams in the plane is realized; compared with the existing connection method, the advantage is that when it is subjected to earthquake action, the external wall panels and prefabricated beams The overall frame can be separated without preventing the free bending, twisting and other deformation of the frame, and the connected U-shaped steel bars can serve the purpose of energy consumption and energy absorption during earthquakes; it is suitable for industrial production, and it is also convenient for on-site construction and installation, saving energy. Go to the site to pour concrete and maintain it, saving time and being green and environmentally friendly.
