Embodiment 1

[0021] Embodiment 1: as figure 1 and figure 2 As shown, a kind of glued bamboo board for structure of the present invention, it comprises core board layer (1) and the hot-pressed layer (2) that is arranged on the both sides of core board layer (1), and core board layer (1) is by thickness 25~ The 30mm structure is made of slats (3) cut out of glued bamboo board GluBam (6), which are made by lateral cold pressing and sanding to determine the thickness. After forming, all slats (3) in the core layer (1) The pressing molding surface of itself is perpendicular to the pressing molding surface of the hot pressing layer (2). The hot-pressed layer (2) is composed of several layers of bamboo curtains (4) and a layer of mats (5). The bamboo curtain (4) is laid by stacking vertical bamboo curtains and horizontal bamboo curtains. The mechanical performance requirements of the board are determined, and the mat (5) can be an ordinary bamboo plywood mat, or can be set as other veneer mate...

Abstract

The invention discloses bamboo plywood for a structure. The bamboo plywood for the structure comprises a core board layer and hot-pressed layers arranged on the two sides of the core board layer. The core board layer is made of battens through lateral cold pressing and gluing and sanding thickness determining, wherein the battens are formed by cutting bamboo plywood GluBam which is used in a structure and has the thickness of 25 mm to 30 mm. The pressed forming surfaces of all the battens in the formed core board layer are perpendicular to pressed forming surfaces of the hot-pressed layers. According to the bamboo plywood for the structure, nails can be driven into two sides of the bamboo plywood, the thickness in each bamboo plywood layer is even, and the thickness tolerance between the plywood layers is small; in addition, the hot-pressing technology efficiency is high, and the mechanical property is high. The bamboo plywood for the structure can completely overcome the inherent defects of the existing plywood GluBam and is used for production and construction of the bamboo structure.

Description

technical field [0001] The invention mainly relates to the field of building materials in civil engineering, in particular to a glued bamboo plate that can be made into stressed components such as glued bamboo beams and glued bamboo columns. Background technique [0002] In today's society, reinforced concrete structures, steel structures and various composite structures with steel and cement as the main raw materials are the most important structural forms in the field of civil engineering. Metallurgy and cement industries have always been high energy consumption and high pollution industries. The production of steel and cement needs to consume a lot of energy and non-renewable natural resources, and at the same time produce a lot of waste water, waste gas and waste residue, which seriously affects the ecological environment and does not conform to sustainable development. requirements. The use of natural, environmentally friendly, and renewable organic materials is proces...
