Adjustable large-area floor channel steel formwork system and its construction method

Abstract

The invention relates to an adjustable large-area floor steel channel formwork system and a construction method of the adjustable large-area floor steel channel formwork system. The system comprises a steel channel formwork, a supporting frame and a batten side mold, and a plurality of stiffening plates with vertical adjusting slot holes are welded in a groove of the steel channel formwork. The supporting frame is composed of vertical rods, horizontal rods and inclined rods, the upper portions of the vertical rods are connected with horizontal connecting parts which are parallel to the horizontal rods and extend into the groove of the formwork, threaded rods connected to the horizontal connecting parts penetrate through the vertical adjusting slot holes and are connected with the stiffening plates in an adjustable mode through nuts, and the top ends of the vertical rods are welded with transverse formwork stopping parts which are perpendicular to and tightly attached to the outer sides of the stiffening plates. The adjustable large-area floor groove steel formwork system further comprises a demolding threaded rod and a rotary hand shank. The construction method includes formwork installing and formwork removing. The adjustable large-area floor groove steel formwork system solves the technical problems that due to the fact that the formwork is not firmly supported and reinforced in an existing large-area floor formwork system, errors of elevation of concrete poured subsequently and flatness of a surface layer are large, formed large-area floor concrete is poor visually, and use functions are affected.

Description

technical field [0001] The invention belongs to the field of formwork engineering, in particular to an adjustable channel steel formwork system for large-area floors and a construction method thereof. Background technique [0002] With the advancement of modern construction technology, the construction quality requirements for large-area floors of underground garages, industrial plants, airports, stations and other buildings are getting higher and higher. Traditional large-area floor formwork generally uses wood formwork or steel formwork. The reinforcement system of wood formwork is generally back corrugated or short wooden squares. The reinforcement system of steel formwork is generally reinforced by surrounding structural columns or driven into the foundation of the floor. Rebar, to connect the rebar to the steel formwork. The steel bars can only limit the displacement of the steel formwork in two horizontal directions, and the steel formwork will also cause vertical dis...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide an adjustable large-area floor channel-steel formwork system and its construction method, to solve the problem of poor reinforcement of the formwork support in the traditional large-area floor formwork system, resulting in the subsequent pouring of concrete elevations and surface layers. There are technical problems such as large flatness errors, poor appearance of formed large-area floor concrete, and affecting use functions.
