Supporting padstone reserved hole mold with self-contraction function

Abstract

The invention discloses a supporting padstone reserved hole mold with a self-contraction function, comprising a mold body; the mold body comprises movable arc plates having one free side and at leastone connection arc plate arranged between the adjacent movable arc plates to provide connection; the movable arc plates and the connection arc plates are spliced to form a sleeve for positioning a reserved hole; a rotating mechanism is arranged between each connection arc plate and the arc plate adjacent to the same to provide rotational connection; when two adjacent movable arc plates move inwardrespectively through the corresponding rotating mechanisms, no mutual interference occurs; the connection mechanisms arranged between the adjacent movable arc plates provide fixed connection for themovable arc plates. The supporting padstone reserved hole mold has flexible and rich assembly modes; with the unique mold structure, the supporting padstone reserved hole mold has the self-contractionfunction and is simple to operate; the supporting padstone reserved hole mold can be reused to avoid waste and is very practical.

Description

technical field [0001] The invention relates to a mold with self-shrinking function for reserved holes for supporting cushion stones. Background technique [0002] At present, in building construction, especially for the concrete pouring operation of supporting pad stones, it is usually necessary to reserve installation holes for the subsequent development of other engineering operations. In the prior art, the traditional reserved hole forming method is to first fix the PVC pipe or iron pipe one by one with iron wire to determine the position of each reserved hole, then pour concrete and chisel out the hole to complete the pre-embedded work, but due to artificial The positioning accuracy of the operation is low, the PVC pipe or the iron pipe cannot be reused, resulting in waste, and the waste in the hole is difficult to clean up, which brings difficulties to the subsequent construction, or the form of a combined mold is used. The specific principle is as follows: The mutual...

In the prior art, the traditional reserved hole forming method is to first fix the PVC pipe or iron pipe one by one with iron wire to determine the position of each reserved hole, then pour concrete and chisel out the hole to complete the pre-embedded work, but due to artificial The positioning accuracy of the operation is low, the PVC pipe or the iron pipe cannot be reused, resulting in waste, and the waste in the hole is difficult to clean up, which brings difficulties to the subsequent construction, or the form of a combined mold is used. The specific principle is as follows: The mutual cooperation between formwork and fasteners is mainly used, but since the assembly of formwork requires various assembly components including straight formwork, curved formwork and baffles, the preparatory work is too long, which not only increases time costs, It will also affect the progress of construction
