Box type high-strength bamboo laminated wood beam and manufacturing method

Abstract

The invention provides a box type high-strength bamboo laminated wood beam and a manufacturing method. The box type high-strength bamboo laminated wood beam structurally comprises a high-strength bamboo laminated wood top board, a high-strength bamboo laminated wood bottom board, high-strength bamboo laminated wood webs and low-density bamboo laminated wood anti-shearing bamboo pins. The high-strength bamboo laminated wood top board and the upper portions of the high-strength bamboo laminated wood webs are connected through clamping grooves A and the low-density bamboo laminated wood anti-shearing bamboo pins A. The high-strength bamboo laminated wood bottom board and the lower portions of the high-strength bamboo laminated wood webs are connected through clamping grooves B and the low-density bamboo laminated wood anti-shearing bamboo pins B. The box type high-strength bamboo laminated wood beam has the beneficial effects that the beam is suitable for a large-span bamboo structure, high in anti-torque rigidity and low in energy consumption and pollution; the height of the beam can be adjusted through the height of the webs according to the stress condition, standardized production is facilitated, the requirements for a fabricated structure and building diversity can be met, the clamping grooves and the bamboo pins are adopted for connection, the technology is simple, connection is reliable, and the quality is easy to control; and a box type section is adopted, the bearing capacity, the deformation capacity and the stability of the beam are improved, materials are saved, the dead weight is low, the manufacturing cost is reduced, and earthquake resistance and energy conservation are better achieved.

Description

technical field [0001] The invention relates to a box-shaped high-strength bamboo glulam beam applicable to large-span construction engineering structures and bridge structures and a preparation method thereof, belonging to the field of engineering technology. Background technique [0002] Environmental and resource issues are imminent. Seeking suitable biomass renewable structural materials is a new direction in the field of contemporary civil engineering. More and more architects are turning their attention to bamboo and wood materials. Bamboo and wood buildings have brought people close The warmth of nature, contemporary bamboo and wood buildings are no longer limited to small-area houses and ordinary residences, more and more public buildings, long-span buildings, and bridges tend to use bamboo and wood materials, and raw bamboo and logs are different in size. The diversity of specifications and mechanical properties cannot directly meet these needs, and raw bamboo and l...

Problems solved by technology

[0005] However, at this stage, my country’s bamboo and wood structure design theory is not perfect, and the design methods are backward. Under the guidance of sustainable development, under the situation of increasingly scarce labor force, it is very meaningful to develop prefabricated and factory-standardized bamboo structure buildings. At the same time, the large-span More and more structures are emerging, and various types of components suitable for large-span bamboo structures are required. Therefore, it is necessary to analyze and design prefabricated and large-span bamboo structures based on modern structural analysis techniques and structural design principles.

[0006] At present, the prefabricated structure with concrete and steel as the main raw materials has the following disadvantages: (1) heavy weight; (2) inconvenient transportation; (3) the size of the components is determined according to the design requirements, which is not universal, which is not conducive to Standardized production; (4) high energy consumption, high pollution, and relatively high cost; the present invention can effectively improve the above conditions
