Prefabricated assembly type concrete wallboard and connecting structure and construction method thereof

Abstract

The invention provides a prefabricated assembly type concrete wallboard and a connecting structure and a construction method thereof. The prefabricated assembly type concrete wallboard comprises a wallboard body, a plurality of vertically formed reinforcing steel bar through holes are formed in the wallboard body, and the reinforcing steel bar through holes are formed by metal corrugated pipes pre-buried before concrete is poured in a component factory. Pouring grooves are formed in the side edge of the wallboard body. Ribs are not exposed out of the four sides of the wallboard of a connectingstructure, field connection is divided into vertical connection and horizontal connection, the vertical connection is that steel bars are inserted into the pre-buried metal corrugated pipes, concreteis poured into the pre-buried metal corrugated pipes, and the vertical steel bars are in lap joint or welding or mechanical connection. The horizontal connection of the wallboard is that truss ribs are placed in the pouring grooves in the side edge of the wallboard, and the necessary vertical steel bars and horizontal steel bars are used as auxiliary materials. The ribs are not exposed on the four sides of the wallboard, and factory production is facilitated. The grouting-sleeve-free process for field connection is low in cost, reliable in connection and high in construction efficiency. The pouring grooves in the four sides of the wallboard and the post-poured concrete form a strong mechanical joint surface, and a good waterproof effect is achieved.

Description

technical field [0001] The invention relates to the technical field of prefabricated building construction, in particular to a prefabricated assembled concrete wall panel and its connection structure and construction method. Background technique [0002] At present, the connection of the upper and lower prefabricated walls of the prefabricated integral concrete wall generally adopts the methods of steel sleeve grouting connection, grout anchor lap joint, bolt connection, and indirect lap joint of double-sided laminated walls. Among them, the steel sleeve grouting connection and the grout-anchor lap joint have problems such as high construction accuracy, difficulty in testing the density, and high cost; the bolted connection has an adverse effect on the weakening of the wall section; the double-sided laminated wall is easy to expand the mold, Problems such as large amount of steel used. In addition, except for the connection structure of the double-sided laminated wall, the ...
