Steel-wood combined formwork and construction method

Abstract

The invention discloses a steel-wood combined formwork, and belongs to the field of building construction. The steel-wood combined formwork comprises a wood formwork, square steel auxiliary back edges, double-square-steel main back edges and fixing and connecting devices. A plurality of openings allowing the fixing and connecting devices to penetrate through are formed in the wood formwork. The square steel auxiliary back edges are fixedly connected to the outer side of the wood formwork. The double-square-steel main back edges are arranged outside the square steel auxiliary back edges. Each double-square-steel main back edge is formed by welding two pieces of square steel, wherein a gap allowing the corresponding fixing and connecting device to penetrate through is arranged between the two pieces of square steel. The double-square-steel main back edges, the square steel auxiliary back edges and the wood formwork are integrally connected and fixed through the fixing and connecting devices. The invention further discloses a construction method of the steel-wood combined formwork. The square steel serves as the main back edges and the auxiliary back edges, special locks are arranged on the joint portions such as exposed corners and holes, the square steel is combined with the wood formwork to form the system of the steel-wood combined formwork, and therefore rigidity and overall stable performance of the combined formwork are enhanced, the smoothness of a wall is improved, construction is easy, convenient and rapid, energy is greatly saved, and cost is reduced.

Description

technical field [0001] The invention relates to a building construction formwork and a construction method, specifically a steel-wood composite formwork and a construction method, which belong to the field of building construction. Background technique [0002] In recent years, the state has actively advocated scientific and technological progress and technological innovation, and vigorously promoted energy conservation, emission reduction, and green construction. The wooden back corrugation of the traditional wall formwork support method has low pressure resistance. When the support load is large, it is prone to instability, affecting the flatness of the wall surface, and the safety performance is poor. [0003] On October 13, 2010, the Chinese invention patent CN1991109B disclosed a process method for combining plywood formwork. It uses large plate plywood as the formwork, and light metal connecting beams as the back of the supporting formwork. The wooden plywood and metal...
