Manufacturing method of prestressed plate components manufactured by adopting cross-laminated timbers

Abstract

The invention discloses a manufacturing method of prestressed slab components manufactured by adopting cross-laminated timbers. The manufacturing method is characterized in that prestressed tendon (3)is positioned in a geometric space formed by drawing out a laminated plate arranged on one side of the outermost layer of a prefabricated cross-laminated timber (1); after the prestressed tendon (3)is subjected to tensioning, an end die is mounted on the end part of the geometric space formed by drawing out the laminated plate arranged on one side of the outermost layer of the prefabricated cross-laminated timber (1); successively, concrete (2) is poured and is then vibrated and leveled; when the strength of the concrete (2) is more than or equal to 2.5MPa, the end die is removed, tensioningis carried out when the concrete (2) is conserved to ensure that the strength is not less than 75 percent of a designed value, and a corrosion prevention measure on an exposed part of the prestressedtendon (3) is made, so that the manufacturing of the prestressed slab components based on the cross-laminated timbers is realized. According to the manufacturing method disclosed by the invention, the problem that the applied prestress of the cross-laminated timber plate components is limited because of the properties of the own materials and the prestress loss is too high after the prestress isapplied to the prestressed tendon are solved.

Description

technical field [0001] The invention relates to a method for making a prestressed plate component made of cross-glued wood, which is suitable for various medium and small bridges and horizontal components of buildings, and belongs to the field of civil engineering. Background technique [0002] With the rapid development of my country's construction industrialization, the research on prefabricated buildings has become more and more popular. Compared with traditional cast-in-place houses, prefabricated houses have the advantages of high degree of industrialization, easy construction quality assurance, short construction period and high economic benefits. The assembly type simplifies the construction process, reduces high-altitude operations, and makes the hoisting of components more convenient, which ensures the safety of the site to a certain extent. With the development of my country's economy and the improvement of people's living standards, the consumption concept of purs...
