Prefabricated semi-recessed façade panels and buildings

Abstract

The invention discloses a prefabricated semi-embedded outer wall panel, comprising a wall body, a first steel grid frame is arranged inside the wall body, a connection hole is opened at the bottom of the wall body, and a pre-embedded locking component is arranged in the connection hole , the embedded locking component includes a connecting column and a passive clamping piece, one end of the connecting column is connected with the first steel mesh frame; the passive clamping piece is connected to the connecting column, which includes at least two clamping pieces, two clamping pieces A clamping space is formed between them, and the embedded steel bars are inserted into the clamping space so that the steel bars and the passive clamping pieces form a second steel mesh frame. In the assembled semi-embedded exterior wall panel provided by the present invention, on the one hand, the passive clamping part is connected to the first steel mesh frame in the wall through the connecting column; on the other hand, the passive clamping part is passively clamped by the clamping part The pre-embedded steel bars of the inserted slab surface are held, so that a second steel mesh frame is formed between the wall body and the slab surface, which improves the connection strength of the connection between the wall body and the slab surface.

Description

technical field [0001] The invention relates to construction technology, in particular to a prefabricated semi-embedded outer wall panel and a building. Background technique [0002] At present, prefabricated buildings have developed rapidly for reasons such as high speed, environmental protection, energy saving, etc. Prefabricated buildings include different parts such as exterior wall panels, stairs, laminated panels, etc. Among them, the exterior wall panels have many installation steps and high positioning requirements. part. [0003] The installation of the prefabricated exterior wall panel in the prior art includes the following steps: [0004] (1) Cleaning up the construction surface; [0005] Clean the surface of the board and the pre-embedded steel bar below the wall panel, and straighten the bent pre-embedded steel bar with special tools. [0006] (2) Paste the bottom sealing strip; [0007] After the floor surface and steel bar surface are cleaned, the gap at ...

Problems solved by technology

However, this has brought negative effects. Since there is no steel grid connection at this position but it is connected by concrete, and the concrete connected here is concrete without aggregate or with low aggregate content for better fluidity. The strength of the connection is low. In order to minimize the size of the weak connection, the existing technology sets the opening on the bottom surface of the outer wall to be smaller, and a sleeve is arranged on the opening, which brings other negative effects , the alignment is difficult, so in the prior art, in the fifth step above, the reflector is used to position the steel bar and the sleeve (ie), which reduces the working efficiency of hoisting
