A large-thickness concrete floor formwork structure and its application method

Abstract

The invention relates to the technical field of floor formwork, and discloses a large-thickness concrete floor formwork structure, which includes a formwork, two cross supports and a flag-shaped support, and the two cross supports and a flag-shaped support are alternately installed on the formwork The bottom of the formwork, the formwork includes a vertical channel steel and an angle steel, the angle steel is installed on the upper side of the right side wall of the channel steel, the two cross brackets are installed on the inner side of the channel steel, and the flag-shaped The bracket is installed on the outside of the channel steel. The structure of the large-thickness concrete floor formwork and its use method, the construction joints formed by this structure are straight and the appearance quality is good. After the cross bracket is separated from the formwork, the cross bracket can be folded , to facilitate the disassembly and transportation of the entire equipment. When the template is separated from the flag-shaped bracket, the flag-shaped bracket can also be folded to facilitate the disassembly and movement of the entire equipment. Small size, short construction period, saving construction cost.

Description

technical field [0001] The invention relates to the technical field of floor formwork, in particular to a large-thickness concrete floor formwork structure 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. [0003] The f...

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
