Novel unit truss type concrete frame structure formwork supporting system and construction method thereof

Abstract

The invention discloses a novel unit truss type concrete frame structure formwork supporting system and a construction method thereof. The structure system comprises a beam bottom supporting part (2)and a floor supporting part (1); the floor supporting part (1) is formed through pin jointing of spliced truss beams used as main ridges and rectangular steel pipes used as secondary ridges; accordingto the truss beams, modularly-designed unit truss pieces (4) are connected in a hinged manner through connecting pins comprising male and female connectors (7) to form the main ridges of a floor formwork support; the beam bottom supporting part (2) is arranged along the beams and is formed through splicing of unit truss pieces (3); and the beam bottom supporting part (2) is connected and fixed through oppositely-pulled rods (5) and inclined supporting rods (6). The supporting system is easy to operate, assembling and greening of project construction are improved, the construction speed is increased, meanwhile, most construction space at the lower part of a cast-in-place floor is saved, simultaneous construction by various work types is facilitated, and the total construction time of the project can be further shortened.

Description

technical field [0001] The present invention relates to a new type of building construction formwork support system, in particular to a novel unit splicing truss type formwork support system. The purpose of the support system. Background technique [0002] The formwork support system used in my country's construction engineering is mainly a variety of scaffolding support systems based on the full support method. Formwork scaffolding construction is one of the major sources of danger on the construction site. With the rapid development of my country's construction industry, the existing The deficiencies of the formwork bracket support system have become increasingly prominent, such as large steel consumption per unit area, more labor for erection, long construction period, poor working conditions on the working surface, and difficulty in inspection and acceptance after erection. Safety and quality problems caused by reasons such as the difficulty in ensuring the standardizati...

Problems solved by technology

At present, the new formwork support system in the industry is the aluminum formwork system supported by poles. Although the construction speed is fast, because the system completely replaces the wood formwork with aluminum formwork, the cost is too high, and it has certain application limitations, which limits its promotion and development.
