A multifunctional reserved hole formwork support device and formwork support method

Abstract

The invention provides a multifunctional device for formworks with reserved holes. The multifunctional device for the formworks with the reserved holes comprises a supporting base, an umbrella-shapedsupport, a compression ring nut and vertical supporting plates, wherein the supporting base is used for fixing a formwork erecting device body and comprises a pedestal and a tubular vertical rod fixedto the pedestal; the umbrella-shaped support is used for providing hole formwork inner bracing and comprises a plurality of telescopic supporting arms which are connected with the tubular vertical rod and uniformly distributed along the circumference of the tubular vertical rod; the compression ring nut is used for adjusting the opening degree of the telescopic supporting arms; the vertical supporting plates are fixed to the tail ends of the telescopic supporting arms respectively and used for fixing a formwork body, and the vertical supporting plates are parallel to the tubular vertical rod.The multifunctional device for the formworks with the reserved holes can fit for the formworks with round holes, square holes and even polygonal holes, the assembly and disassembly operation is convenient, the device can be reused, wood waste is reduced, and the device is environmentally friendly.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a formwork support device and a formwork support method for a reserved opening of a multifunctional cast-in-place floor (flat) slab. Background technique [0002] In the process of building construction, it is often necessary to set reserved openings on the cast-in-place floor (flat) slab, and the most common ones are square openings and circular openings. Under normal circumstances, it is not difficult to reserve a square opening for formwork. You only need to cut the wooden frame according to the design size of the reserved opening to be used as the inner support of the opening formwork, and fix the inner support on the bottom formwork of the opening. The square bar of the wooden formwork is used as the side formwork of the hole, and then it can be fixed. When the circular hole is reserved for formwork support, when the plastic pipe material with the same size as...

Problems solved by technology

These molds have alleviated the problem of difficulty in forming the reserved circular openings to a certain extent, but since these molds do not have the function of changing diameters, they still cannot meet the needs of various opening sizes in actual construction and production, and have not achieved formwork support. Fast positioning, accurate control of the size of the hole formwork, convenient formwork support, quick formwork removal, and good hole forming effect
