Quick-release clear water formwork system and construction method

Abstract

The invention discloses a quick-release clear water formwork system and a construction method. Preconstruction personnel, material and technology preparation work is made according to construction organization design. A drawing is examined, an engineering construction scheme is determined, and a formwork is manufactured according to the design drawing requirements in combination with a structure drawing, an architectural drawing, a node detail drawing and construction specifications; the formwork project of the project follows the principle that a shear wall column is installed firstly and then a beam plate face is installed, and wall column formwork installation, beam plate formwork installation and top plate formwork installation are conducted in sequence. According to the method, a high-quality engineering project can be completed, a fixing formwork system is higher in integrity, a novel reinforcing system improves the concrete forming effect, the vertical five-flat five-effect can be achieved, the formwork structure and the supporting structure are adopted, a floor supporting structure dismantled from the bottom layer can be transferred to the upper layer to be used for supporting a floor formwork of the upper layer, and the construction efficiency is improved. Therefore, the construction period is greatly shortened, and the construction efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of building formwork systems, in particular to a quick-dismantling clear water formwork system and a construction method. Background technique [0002] At present, building construction basically adopts cast-in-place concrete structure engineering construction, and the building formwork structure used for construction is mainly composed of three parts: panels, support structures and connectors. The panel is a load-bearing slab that directly contacts the cast-in-place concrete; the support structure is a temporary structure that supports the panel, concrete and construction loads, ensuring that the building formwork structure is firmly combined without deformation or damage; the connector is the connection between the panel and the support The accessories that are connected into a whole structure usually use wooden formwork as the panel at present, and the supporting structure is generally connected by wooden...

AI Technical Summary

Problems solved by technology

This kind of formwork system mainly has the following disadvantages: on the one hand, the strength of the wooden formwork is low, and it needs a lot of vertical poles to support it. It is neither fast nor safe to disassemble; 7-8 times, it needs to be scrapped, and the reuse rate is low; wooden formwork is easy to bond with concrete. Concrete surfaces leave criss-cross seam streaks

On the other hand, the existing support structure has a large amount of frames, is experienced, heavy, and time-consuming and laborious to install and disassemble; the support structure and the panel have a low degree of integration and cannot be used effectively; the waste of support structure materials is extremely serious, which brings great safety hazards operation method;

[0003] The traditional formwork matching causes a lot of waste. The traditional wooden formwork can be cut at will and is flexible and changeable. However, the wooden board has poor pressure resistance, unstable pouring quality, high labor costs, and high secondary correction costs. The quality of the aluminum formwork is standard and the efficiency is excellent. However, the input cost is high, the first assembly time is long, and the maintenance cost of aluminum formwork is high. The formwork and support structure used in the traditional formwork construction method are often not fully utilized, resulting in slow construction progress and low efficiency. During the process, when using wooden formwork, tools such as iron nails are used to fix it, and it is not convenient for secondary use after removal. When using metal formwork, bolts are used to connect, the construction process is complicated, and the construction period is slowed down.
