Quick die replacing device for prefabricated member hole and using method of quick die replacing device

Abstract

The invention relates to a quick die replacing device for a prefabricated member hole. The quick die replacing device comprises rubber magnetic box corner connecting pieces, a pressing plate and edge dies. The rubber magnetic box corner connecting pieces and the edge dies are alternatively connected end to end to form a closed hole flat die structure, the pressing plate is installed above the rubber magnetic box corner connecting pieces, and the two ends of the pressing plate are tightly pressed above two adjacent edge dies correspondingly. The invention further comprises a using method of the quick die replacing device for the prefabricated member hole. The quick die replacing device has the beneficial effects that the structure is simple, the die replacing speed is high, fewer welding processes exist, cleaning carried out between die manufacturing process and in the later period is better saved, the manufactured hole has the beneficial effects of being high in quality yield and the like, and use is convenient.

Description

technical field [0001] The invention relates to a formwork for pouring a prefabricated part and a method for using the same, in particular to a quick mold change device for a prefabricated part opening and a method for using the same. Background technique [0002] At present, prefabricated concrete is widely used to build houses. First, it can shorten the construction period of the house. Second, it can ensure that the quality of the house construction will not be affected by the external environment (temperature, moderate climate conditions, etc.), and it can also meet the inconvenience of on-site pouring. house building needs. Concrete prefabricated components are usually poured with templates on trolleys during the preparation process. In order to improve the production efficiency of prefabricated parts, the reuse rate of templates and the rapid cleaning of trolleys, a quick mold change system came into being. As a common structural wall panel in prefabricated parts, it ...

Problems solved by technology

[0003] CN204585499U has announced a kind of prefabricated concrete member opening side formwork structure, comprises bamboo plywood, aluminum profile frame and magnetic box, and bamboo plywood is connected aluminum profile frame by bolt, and this aluminum profile frame right side is provided with draw-in groove 1, and magnetic box left The side is provided with the card slot 2 matching the size of the card slot 1. The magnetic box is connected to the aluminum profile frame through the card slot 1 and the card slot 2. This utility model is only fixed for the side mold of the hole, and does not involve the hole The corner of the hole, and because the hole is located inside the prefabricated wall panel, it is impossible to complete the effective pouring at the corner with the same structure as the prefabricated wall panel, so special corner connectors need to be set for the corner of the hole, and now The use of corner connectors in the prior art in the quick mold change system at the entrance cannot simultaneously achieve the purposes of quick disassembly, high stability, and better concrete pouring effects.

In addition, the side molds of the above-mentioned patents are relatively cumbersome to fix, and the structure of the side molds is also relatively complicated, which is not conducive to the realization of quick mold change and saving of production costs. Mold changing device with good effect and simple structure and its application method
