An installation and fixing device for a combined formwork for a splicing seam of a prefabricated building laminated board

Abstract

An installation and fixing device for a composite formwork for a splicing seam of a prefabricated building laminated board, comprising a bottom bracket (1) and a horizontal steel beam (5), characterized in that a walking device (2) is fixed at the lower end of the bottom bracket (1). , a vertical column (3) is vertically fixed below both ends of the horizontal steel beam (5), the lower end of the vertical column (3) is installed on the upper end of the bottom bracket (1) through a vertical lifting device, and the horizontal steel beam (5) is provided with A hanging sliding track (8), a plurality of sliding seats (9) are installed on the hanging sliding track (8), a hanging rod fixing frame (10) is respectively fixed on the bottom of the sliding seat (9), and the hanging rod fixing frame (10) Through the locking and adjustable device being connected with the upper end of the vertical hanger rod (11), the present invention has a reasonable structure, can accurately adjust the height of the support structure and the bottom formwork according to the needs, and can also hoist, move and align other building components. The overall molding effect is good, and the construction efficiency has been improved.

Description

technical field [0001] The invention relates to an installation and fixing device for a combined template, in particular to an installation and fixing device for a combined template for a splicing seam of a prefabricated building laminated board, and belongs to the technical field of construction engineering. Background technique [0002] With the wave of prefabricated building construction in my country's construction industry, the production methods in the construction field have undergone great changes. The floors in prefabricated concrete structures mostly use concrete truss and steel bars to laminate floors. The prefabricated laminate is composed of a prefabricated base plate and a cast-in-place floor slab at the bottom, and the whole floor slab is integrated by the combination of the prefabricated base plate and the cast-in-place concrete. Due to the limited width of the prefabricated floor, the adjacent prefabricated floor needs to reserve a certain width of joints. T...

Problems solved by technology

[0003] The purpose of the present invention is to solve the difficulty in installing and fixing the combined formwork during construction of the existing prefabricated laminated slabs, which is restricted by the rapid construction of prefabricated buildings and the limited installation space of traditional formwork, so that the construction of the next floor will be carried out simultaneously. In addition, it is easy to lift the prefabricated bottom slab during the process of supporting the formwork, which affects the construction accuracy of the floor slab. After the formwork is removed, local deformation and cracking are easy to occur. Defects and deficiencies. Provide One has a reasonable structure, adopts a movable suspension structure, fixes the combined formwork through the upper part, and can precisely adjust the height of the support structure and the bottom formwork according to the needs, and the force is uniform, avoiding the prefabricated bottom plate from jacking up and demoulding There will be no local deformation and cracking in the end, the overall forming effect of the floor slab is good, and the construction efficiency has been improved. It is a prefabricated building composite panel splicing joint joint formwork installation and fixing device.
