A kind of production method of plastic surface building square timber

Abstract

The invention discloses a method for producing plastic-surface building square timber. The method sequentially includes the steps of drilling the square timber, threading counter bores internally, threading the two ends of rebar externally, conducting heating, conducting dehumidifying, laying asbestos cloth, installing the rebar, spreading a binding material, conducting squeezing, covering film, roll-in compounding, conducting cooling, conducting solidifying, conducting cutting, conducting forming, polishing the lower surface of the square timber, notching the plastic-surface building square timber, installing frames and the like. The counter bores are formed in the surface the square timber by drilling and in threaded connection with the rebar, the rebar plays a role in reinforcing the square timber and plastic layers and making the connection of the square timber and the plastic layers tight, glue failure is not easy to occur, the service life of the plastic-surface building square timber is prolonged, when the square timber and the plastic layer are connected, asbestos layers are arranged among connection layers, silica gel particles are uniformly spread between the connection layers, the tightness of the connection of the square timber and the plastic layers can be increased, finally, the outer portion of the plastic-surface building square timber is provided with aluminum alloy frames, the strength of the plastic-surface building square timber is increased, the glue failure of the plastic-surface building square timber is prevented, and the flatness of the plastic-surface building square timber can not be affected.

Description

technical field [0001] The invention relates to the technical field of building templates, in particular to a production method of plastic-faced building square timber. Background technique [0002] Building formwork is an important construction tool for concrete structure engineering, and its quality is directly related to the quality, cost and benefit of engineering construction. According to statistics, in cast-in-place concrete structure engineering, formwork engineering generally accounts for 20% to 30% of the cost of concrete structure engineering, and accounts for 30% to 40% of the engineering labor. With the rapid development of my country's real estate industry, the amount of building formwork is increasing year by year. It is estimated that in 2012, the output of my country's building formwork industry will reach about 220 million square meters. Existing building formwork used mainly contains steel formwork, wood plywood formwork and bamboo plywood formwork. The ...

Problems solved by technology

The surface layer and the substrate form cross-links in the horizontal and vertical directions, the connection is firm, it is not easy to delaminate and crack, the service life is long, and the quality of the formwork is good. Fabric layers or other structures that are helpful for bonding, and there is no reinforcing structure directly bonded between the layers, it is easy to break after a long time of use, and the outer edge has no frame, it is easy to open the glue and has a short service life. Therefore, we propose a plastic Production method of face building square timber
