Novel big-thickness concrete terrace formwork structure, and use method thereof

Abstract

The invention relates to the technical field of terrace formworks, and discloses a novel big-thickness concrete terrace formwork structure. The novel big-thickness concrete terrace formwork structurecomprises a formwork, two cross-shaped brackets and a flag-shaped bracket, wherein the two cross-shaped brackets and the flag-shaped bracket are installed on the bottom of the formwork in a staggeredway; the formwork comprises one piece of vertical groove steel and one piece of angle steel, wherein the angle steel is installed on the upper side of the right side wall of the groove steel; the twocross-shaped brackets are installed on the inner side of the groove steel; and the flag-shaped bracket is installed on the outer side of the groove steel. By use of the novel big-thickness concrete terrace formwork structure and the use method thereof, a construction joint formed by the structure has a smooth and straight line and good apparent mass. After the cross-shaped brackets are separated from the formwork, the cross-shaped brackets can be folded so as to be convenient for disassembling, assembling and transporting whole equipment. After the formwork and the flag-shaped brackets are separated, the flag-shaped brackets can be folded so as to be convenient for assembling, disassembling and moving the whole equipment. The whole equipment has a high assembling and disassembling speed, has a high circulation frequency, a small damage rate and a short construction period, and saves construction cost.

Description

technical field [0001] The invention relates to the technical field of floor formwork, in particular to a novel structure of a large-thickness concrete floor formwork and a method for using the same. Background technique [0002] With the development of society and the improvement of people's living standards, people's pursuit of plant area, space and use is getting higher and higher. The function of the plant is becoming more and more powerful, and it has gradually developed into a collection of processing and production, product display, product storage and product delivery. Multi-functional space, assembly line operation is becoming more and more popular. In order to prevent floor cracks caused by concrete shrinkage and uneven settlement, heavy-duty concrete floors in large workshops are often divided into blocks and regions. If you want to have high-quality and beautiful construction joints, the selection and support of the floor formwork is particularly important. [...

AI Technical Summary

Problems solved by technology

[0003] The floor formwork has gradually evolved from the original wood formwork to a steel formwork. The wood formwork system is composed of plywood and wood squares. The biggest advantage of wood formwork is flexible construction. The disadvantages are slow processing and installation speed, straightness and appearance of the new formwork. The quality is good, but the wooden formwork will soften and deform when exposed to water. As the number of turnovers increases, the straightness and apparent quality of the construction joints will continue to decline. At the same time, the upper surface of the formwork is easy to stick during the process of mechanical closing and grinding Mortar, when removed, will cause damage to the surface layer and edges and corners, affecting the appearance quality

Most of the steel forms currently used are channel steel. Channel steel has gradually replaced wooden formwork due to its advantages of high rigidity, flatness, good straightness, fast installation and disassembly, and many turnover times. During the construction process, it can be used according to the floor. Choose channel steel of different specifications for the thickness, or a combination of multiple specifications of channel steel. In order to facilitate the control of the elevation and flatness of the concrete surface of the floor, the elevation of the floor surface is often controlled by controlling the elevation of the channel steel leg width during installation. The accuracy is greatly improved compared with the wooden formwork, but the concrete grout on the wide surface of the channel steel legs cannot be completely cleaned during construction, and it will stick to the concrete on the floor surface, and the edges and corners and the adjacent surface will also be damaged when the formwork is removed
