Abstract

The invention discloses a cross laminated timber (CLT)-assembled wood arch structure which comprises one or more wood arch bodies arranged along a width direction of a wood arch, wherein each wood arch body is respectively formed by splicing a plurality of CLTs in sequence along a length direction of the wood arch; two adjacent CLTs are fixed by side connecting metal pieces; one or more compositefastening and tensioning layers are fixed on an upper surface of each wood arch body; each CLT has a cross section of isosceles trapezoid and has an upper surface longer than a lower surface; the composite fastening and tensioning layers are carbon fiber layers, glass fiber layers or steel strips; and the wood arch bodies and the composite fastening and tensioning layers thereon are in an arched state after being mounted in place and are in a flat plate state when being transported and stacked for storage. The CLT-assembled wood arch structure is convenient to be transported, simple and rapidto be assembled, and short in on-site construction time by adopting a manner of factory prefabrication and on-site local assembly, and is capable of effectively utilizing dimensional stability of theCLTs and greatly improving a utilization rate of compressive strength.

Description

technical field

[0001] The invention provides an assembled cross-glued wood arch structure, which belongs to the technical field of assembled wooden structures. Background technique

[0002] Prefabricated wooden structure buildings are pre-produced in a professional factory with some or all of the wooden structural parts, transported to the construction site for assembly. The prefabricated structure is a fundamental change to the traditional construction method. Compared with the traditional construction method, the prefabricated building adopts the method of factory assembly line production and on-site rapid hoisting, which can increase the speed of construction and reduce the amount of construction on site. At the same time, it is energy-saving. , material saving, noise reduction and other aspects have a significant effect.

[0003] Cross laminated timber (CLT) is a new type of engineered wood product, which consists of at least three layers of solid wood sawn timber or c...
