Fastening device and method of building template

Abstract

The invention relates to a fastening device and method of a building template. The fastening device of the building template comprises a reinforcing rod piece, a first stabilizing piece and a second stabilizing piece, a fixing pin for being inserted in a fixing hole and trapezoid positioning pins for being inserted in strip-shaped fastening holes and strip-shaped installation holes. The fixing hole is formed in the side wall of one end of the reinforcing rod piece, and a plurality of strip-shaped installation holes are formed in the side wall of the other end of the reinforcing rod piece; anda connecting sleeve casing sleeves the end, provided with the strip-shaped installation holes, of the reinforcing rod piece, the strip-shaped fastening holes are formed in the connecting sleeve, in the multiple strip-shaped fastening holes, in the two strip-shaped fastening holes formed in the two ends, at least the strip-shaped fastening hole which is close to the second stabilizing piece extendsto the end surface of the connecting sleeve. The fastening device and method of the building template have the beneficial effects that clamping of a column body is realized, construction is convenient, simple and fast, the forming effect is good, the cost is greatly saved, the repetition using rate is high, the stabilizing rate is better, the quality assurance rate is high, and the size is more accurate.

Description

technical field [0001] The invention relates to the technical field of building construction equipment, in particular to a building formwork fastening device and a fastening method. Background technique [0002] With the development of the construction industry, there are more and more buildings with high-rise and frame structures. The square columns in most buildings still use traditional formwork reinforcement technologies such as steel pipe fasteners and threaded screws. The traditional technology is not only affected by the construction level of the construction personnel, but also with the continuous improvement of construction requirements and difficulties, many insurmountable construction problems arise. For example: when the size of the square column is large, it is easy to have uneven force on the reinforcement, and it is easy to cause the column to bulge. Or the deviation is large. When using the threaded screw for reinforcement, the screw passes through the column...

Problems solved by technology

The traditional technology is not only affected by the construction level of the construction personnel, but also with the continuous improvement of construction requirements and difficulties, many insurmountable construction problems arise. For example: when the size of the square column is large, it is easy to have uneven force on the reinforcement, and it is easy to cause the column to bulge. Or the deviation is large. When using the threaded screw for reinforcement, the screw passes through the column. After the construction is completed, there will be holes in the column that will affect the strength and aesthetics of the column.

Using the traditional fastening method to reinforce the screw will damage and strengthen the nut and other materials will be lost or lost, resulting in waste of materials. The traditional technology can no longer meet the current construction needs.
