Pre-embedded shear keyway box for prefabricated exterior wall panels and its processing method

Abstract

The invention discloses a pre-buried shear key connector box for a precast facade panel and a machining method of the pre-buried shear key connector box. The pre-buried shear key connector box comprises an upper top plate, a lower bottom plate, a box body and a connecting strand, wherein a strand penetrating hole is formed in the lower bottom plate; the box body is formed by arranging three lateral plates in a surrounding manner; the connecting strand penetrates through the strand penetrating hole; the side, where no lateral plate is arranged, of the box body is an open side; the upper top plate is inclined to the outer side of the box body; the two side plates adjacent to the open side and the lower bottom plate are inclined to the inner side of the box body; the two side plates are arranged to form ribs; the pre-buried pin of the connecting strand is pre-buried in the precast facade panel; after treated with concrete placement, the pre-buried shear key connector box, a floor and a beam together form a shear connector. The pre-buried shear key connector box has the advantages that the structure is simple; the manufacture is easy; standard batch production on a trolley can be realized; the quality is controllable; pollution and material waste are avoided; the production efficiency is high; the transportation, loading, construction and exterior wall decoration are convenient; the shear and vibration resistance of a building main body is improved.

Description

technical field [0001] The invention belongs to the technical field of fixed buildings, and in particular relates to a pre-buried shear force keyway box of a prefabricated exterior wall panel and a processing method thereof. Background technique [0002] Existing prefabricated exterior wall panels do not have a pre-embedded shear keyway box structure, so prefabricated exterior wall panels are prefabricated with outstretched anchoring steel bars. These anchoring steel bars must be bent during transportation and construction to reduce the strength of the damaged steel bars. The operation process is complicated; and when the prefabricated exterior wall panels are produced on the trolley, due to the outstretched anchoring steel bars, one side of the inner leaf plate can only be upward, so that the decoration of the outer wall surface of the outer leaf plate cannot be carried out; in addition, the prefabricated exterior wall panels There is no shear key connection structure betwe...

[0002] Existing prefabricated exterior wall panels do not have a pre-embedded shear keyway box structure, so prefabricated exterior wall panels are prefabricated with outstretched anchoring steel bars. These anchoring steel bars must be bent during transportation and construction to reduce the damaged strength of the steel bars. The operation process is complicated; and when the prefabricated exterior wall panels are produced on the trolley, due to the outstretched anchoring steel bars, one side of the inner leaf plate can only be upward, so that the decoration of the outer wall surface of the outer leaf plate cannot be carried out; in addition, the prefabricated exterior wall panels There is no shear key connection structure between the wall panel and the floor slab, and the structural strength is low, which is prone to displacement and affects the building quality
