A kind of preparation method of prestressed basalt fiber board composite wooden beam

Abstract

The invention discloses a pre-stress basalt fiber board composite wood beam which comprises wood boards and basalt fiber boards, wherein the wood boards in the same layer of the composite beam are spliced into a whole in the length directions of the wood boards; a splicing part between two upper and lower adjacent layers of wood boards in the thickness directions of the wood boards are staggered; basalt fiber cloth wraps the outer part of each splicing part and spliced outside the splicing part; the basalt fiber boards are arranged in a though manner along the length of the composite beam and bonded with two sides of the wood board on the outmost side of the composite beam; the basalt fiber boards comprise first basalt fiber boards arranged on the inner sides of the wood boards and second basalt fiber boards arranged on the outer sides of the wood boards; the second basalt fiber boards are reinforced boards; pre-tress is applied to the second basalt fiber boards. A preparation method of the pre-stress basalt fiber board composite wood beam comprises the following steps: manufacturing the composite wood beam, generating pre-deformation, rebounding for generating pre-tension, reversing by 180 degrees and forming a pre-tress composite wood beam component. According to the pre-stress basalt fiber board composite wood beam, the technical problems of high consumption of overall wood, relatively high cost, relatively low utilization rate of short wood materials with ordinary lengths and ordinary diameters, great possibility of causing of great material waste and unreasonable use of the wood in the conventional wood structure construction can be solved.

Description

technical field [0001] The invention relates to a method for preparing a composite wooden beam used in construction engineering, in particular to a method for preparing a composite wooden beam using prestressed basalt fiber boards. Background technique [0002] Nowadays, it is an indisputable fact that the world's forest resources are gradually decreasing, and the trend of timber supply is becoming increasingly tense. In order to ensure that the wooden beams in the wooden structure can meet the design requirements in the current building construction, the whole wood with a large cross-sectional area is usually selected, resulting in a large amount of wood, which causes a great waste of wood resources and high costs. [0003] In the construction of wooden structures, short wood materials of ordinary length and ordinary diameter are usually used as auxiliary components such as corrugated boards, backing plates, formwork, etc., which cannot be used as the main structural compon...
