Embodiment Construction

[0012] The present invention will be further described below in conjunction with specific embodiments.

[0013] Such as figure 1 As shown, a fiber-reinforced bamboo-wood composite CLT beam (board), the main structural components include the upper timber member 1-1, the lower timber member 1-2 along the beam (board) length direction; and the beam (board) length direction The bamboo members 2 arranged orthogonally; and the reinforcing fiber layer 2 distributed between the lower surface of the bamboo member and the underwood member layer.

[0014] This kind of fiber-reinforced bamboo-wood composite CLT beam (board) is made. First, the underwood component 1-1 is laid flat, and then the reinforced fiber layer 3 of the same size is placed on top of the wooden component 1-2, using epoxy resin structure Adhesive glues the two together, and then lay the bamboo member 2 perpendicularly and orthogonally to the upper surface of the reinforcing fiber layer 3, glue it with epoxy structural adhes...

Abstract

The invention discloses a fiber-reinforced bamboo-wood composite CLT beam (plate) comprising an upper wood component and a lower component in the plate (beam) length direction and further comprising abamboo component and a lower reinforced fiber layer, wherein the bamboo component and the plate (beam) length direction are arranged in an orthogonal mode, and the lower reinforced fiber layer is distributed between the bamboo component and the lower wood component layer. The fiber-reinforced bamboo-wood composite CLT beam (plate) has the advantages that the fiber-reinforced bamboo-wood combinedCLT beam (plate) is the same as a traditional CLT component, the good size stability, fire resistance and heat insulation and sound insulation performance are achieved, factory modular production andprefabrication can be achieved, assembling is also convenient and rapid, and the environment friendly effect is achieved. Compared with the traditional CLT component of the same size, the anti-shearing strength, the anti-bending bearing capacity, the strength weight ratio and the like of the fiber-reinforced bamboo-wood combined CLT beam (plate) are improved, and the strength utilization rate of the component can be improved.

Description

Technical field [0001] The invention relates to the field of civil engineering structures, in particular to a fiber-reinforced bamboo-wood composite CLT beam (board). Background technique [0002] CLT technology has attracted more and more attention at home and abroad. Traditional CLT wood components have good dimensional stability, fire resistance, and heat insulation and sound insulation performance. CLT can realize modular production and prefabrication in the factory, and it is convenient and quick to assemble, and the construction period is short. A green and environmentally friendly structural component. However, mechanical performance indexes such as strength utilization rate and shear strength are not ideal. [0003] my country's fast-growing wood (poplar, pine, eucalyptus, etc.) and bamboo resources are quite abundant, and various fiber reinforcement materials have ultra-high tensile strength. If local wood and bamboo resources can be fully utilized to produce heavy-duty ...
