Concrete external wallboard reverse-driving forming device and forming method thereof

Abstract

The invention discloses a concrete external wallboard reverse-driving forming device and a forming method thereof, which are used in an assembly type building. According to the technical scheme, the key point is that the concrete external wallboard reverse-driving forming device comprises a forming mould, wherein a forming cavity is arranged on the forming mould; a dry sand layer is paved on the bottom of the forming cavity; stone plates are paved on the dry sand layer at intervals; a chamber used for pouring concrete is formed above the stone plates; a reinforcement cage for pressing the stone plates is arranged in the chamber; the dry sand layer is paved in the forming cavity, and uneven outer surfaces of the stone plates can be sunken into the dry sand layer very well during paving of the stone plates, so that the stone plates are paved stably, dry sand is paved in interval slots, the stone plates can be stably pressed by the reinforcement cage, the dry sand in the interval slots can achieve the blocking effect on concrete during follow-up concrete pouring, concrete can be effectively prevented from flowing to the surfaces of the stone plates, operations are simple, convenient and quick; and moreover, the dry sand is low in cost and can be repeatedly utilized, so that production cost is reduced.

Description

technical field [0001] The invention relates to the field of counter-beating of stone materials, in particular to a device for forming a counter-beating of a concrete outer wall panel and a forming method thereof. Background technique [0002] Concrete exterior wall slab back-beating refers to the prefabricated building components that are prefabricated by hammering the decorative stone for the exterior wall of the building into the concrete in the factory in advance. In order to improve the aesthetics, the stone slabs fixed on the exterior wall are usually arranged at intervals at present, and There will be uneven lines on the outer surface of the stone slabs. During the forming process, by placing stone slabs at intervals in the forming mold, interval grooves will be formed between adjacent stone slabs, and a steel cage will be placed on the stone slabs, and then concrete will be poured and solidified before forming. , but due to the uneven surface of the stone slab, in or...

[0002] Concrete exterior wall slab back-beating refers to the prefabricated building components that are prefabricated by hammering the decorative stone for the exterior wall of the building into the concrete in the factory in advance. In order to improve the aesthetics, the stone slabs fixed on the exterior wall are usually arranged at intervals at present, and There will be uneven lines on the outer surface of the stone slabs. During the forming process, by placing stone slabs at intervals in the forming mold, interval grooves will be formed between adjacent stone slabs, and a steel cage will be placed on the stone slabs, and then concrete will be poured and solidified before forming. , but due to the uneven surface of the stone slab, in order to make it stable, there is currently a way to solve the problem by applying glue at the bottom of the forming mold. Adhesive method, the adhesive layer is separated from the wall after the subsequent molding is completed, but this will cause the subsequent adhesive layer to be unusable, and the laying of the adhesive layer is labor-intensive and time-consuming, and increases the production cost
