Construction device for one-time forming of pre-pressing grooves

Abstract

The invention discloses a construction device for one-time forming of pre-pressing grooves. The construction device comprises side wing fixing steel plates and an embedded U-shaped steel plate, the side wing fixing steel plates are symmetrically welded to the two sides of the embedded U-shaped steel plate, arc-shaped end plates are welded to the two ends of the embedded U-shaped steel plate, and two sets of screw holes are symmetrically formed in the side wing fixing steel plates at the two sides; and screws are arranged in the screw holes. According to the construction device, a positioning steel plate can be fixed to a formwork, after the levelness of the positioning steel plate is adjusted, the side wing fixing steel plates and the embedded U-shaped steel plate are connected with the positioning steel plate, the side wing fixing steel plates are also fixed to the formwork through the screws, and therefore the pre-pressing groove can be formed in the embedded U-shaped steel plate after concrete is poured, the purpose of one-time forming is achieved, the construction efficiency is improved, the quality problems of deviation, cracking, blocking and the like of an embedded pipe aresolved, overhauling and maintenance are convenient, the construction device can be suitable for accurate pre-pressing grooves of pipeline structures with different pipe diameters, and the constructiondevice has multiple purposes in installation of the pipelines with different lengths.

Description

technical field [0001] The invention relates to a construction device for one-time forming of a pre-pressing groove, which belongs to the technical field of building construction. Background technique [0002] For the installation of electromechanical pipelines in structural walls, generally the electromechanical pipelines are pre-embedded with the structure or laid after the structure is grooved. When the mechanical and electrical pipelines are pre-embedded along with the structure, it is necessary to pre-embed hollow wooden boxes during the structural reinforcement binding stage or bind and fix the mechanical and electrical pipelines inside the steel bars. During the concrete pouring process, the wooden boxes or mechanical and electrical pipelines are prone to deviation and rupture, and the reserved openings are blocked. And other issues. However, laying pipelines after the structure is slotted will cause irreversible damage to the structure, destroying the safety and sta...
