Embodiment Construction

[0030] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0031] like figure 1 , 2 , 3, and 4, the steel-wood composite formwork of the present invention includes plywood 6, square steel secondary back corrugated 5, both sides steel main back corrugated 4, wall-penetrating screw rod 1, tapered nut 2, steel gasket 3, hole lockset 9, Male angle lock 11, wherein the thickness of plywood 6 is 15mm, and according to the construction needs, a plurality of drilling holes for the wall-through screw 1 to pass through; , drilling, and fixed on the back side of the assembled plywood 6 with ordinary iron nails, which is convenient for reassembly after dismantling; The steel secondary corrugations 5 are perpendicular to each other, and the square steel secondary corrugations 5 are made by welding double 50*30*2.5 square steels, and the inner corners are made into an "L"-shaped right-angle steel main corrugation 13 on both side...

Abstract

The invention discloses a steel-wood composite formwork, which belongs to the field of building construction. The invention includes wooden formwork, square steel secondary corrugations, steel main corrugations on both sides and fixed connection devices. The wooden formwork is provided with a number of openings for the fixed connection devices to pass through, and the square steel secondary corrugations are fixedly connected to the outside of the formwork. The main back flute of steel on both sides is installed on the outside of the secondary back flute of square steel. The main back flute of steel on both sides is welded by two square steels. The flute is connected and fixed as a whole with the square steel back flute and wooden formwork through a fixed connection device. The invention also discloses a construction method of the steel-wood composite template. The invention adopts square steel as the main and secondary back corrugated, and is equipped with special locks at joints such as external corners and openings, and forms a steel-wood composite formwork system with wooden formwork, which strengthens the rigidity and overall stability of the combined formwork, and improves the smoothness of the wall The construction is simple and fast, which greatly saves energy and reduces costs.

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...
