Detachable cast-in-place concrete reserved hole mold

Abstract

The invention relates to a detachable cast-in-place concrete reserved hole mold, and relates to the field of building construction, and the reserved hole mold comprises an isolation box which is hollow and is provided with openings in the top and the bottom, a top plate detachably connected to the opening in the top of the isolation box, and a connecting assembly which is arranged on the inner side wall of the isolation box and is used for fixing the isolation box to a floor; the isolation box comprises four side plates, the adjacent side plates are hinged, and each side plate comprises two supporting plates which are hinged to each other; a plurality of mounting plates are fixedly arranged on the inner side wall of the isolation box in the circumferential direction of the isolation box, the mounting plates are located on the same horizontal plane, and the top plate abuts against the upper surfaces of the mounting plates at the same time; a synchronous contraction mechanism used for driving the four side plates to sink inwards at the same time is arranged between the isolation box and the top plate. The device has the effects that constructors can conveniently apply force to the isolation box to completely dismantle the isolation box, so that follow-up recycling of the isolation box is facilitated, and the resource utilization rate and the construction efficiency are improved.

Description

technical field [0001] The present application relates to the field of building construction, in particular to a detachable cast-in-place concrete reserved hole mold. Background technique [0002] The bridge frame is divided into trough type, tray type, ladder frame type, mesh type and other structures. The bridge frame in the building can be erected independently, or it can be laid on various buildings (structures) and pipe gallery supports. It is mainly used to protect cables, pipes, etc. [0003] At present, high-rise buildings usually include the building body, multi-storey floors and a large number of bridges, cables and pipes. The bridges need to run through each floor, so the corresponding reserved holes need to be opened in advance on the floors for the installation of bridges, cables and pipes. When the construction workers lay mortar or concrete on the floor, in order to avoid the reserved holes, they usually install an isolation box at the position of the reserve...

AI Technical Summary

Problems solved by technology

[0003] At present, high-rise buildings usually include a building body, multi-layer floors, and a large number of bridges, cables, and pipes. The bridges need to run through each floor, so corresponding reserved holes need to be opened in advance on the floor for the installation of bridges, cables, and pipes. When construction personnel lay mortar or concrete on the floor, in order to avoid the reserved hole, an isolation box is usually installed at the position of the reserved hole, and the isolation box is removed after the mortar or concrete is solidified; however, after the mortar or concrete solidifies It will adhere to the outer wall of the isolation box, and the isolation box is surrounded by mortar or concrete. The adhesion strength is relatively high, and it is difficult for the construction personnel to exert force on the isolation box, which makes it difficult to completely remove the isolation box. Therefore, destructive demolition is usually used, resulting in massive waste of resources
