Bamboo laminated wood frame structure beam-column joint

Abstract

The invention discloses a bamboo laminated wood frame structure beam-column joint. The bamboo laminated wood frame structure beam-column joint comprises double-limb columns arranged in parallel and a horizontal beam clamped between the double-limb columns, the horizontal beam and the double-limb columns are connected and fixed through fasteners, and inclined struts made of a same material are connected between the lower side of the horizontal beam and the double-limb columns through fasteners. The bamboo laminated wood frame structure joint can resist lateral horizontal loads (wind, earthquakes and the like), special shear walls or supporting structures do not need to be arranged, the rigidity of the frame beam column joint is improved, the bending moment resisting capacity of the joint is improved through the structural measures that the joint is provided with the short inclined struts and the like, therefore, a frame structure can bear horizontal load, the building space is open, and use is convenient. The column is the double-limb column, so that bamboo materials can be saved, and processing is convenient; the beams and the inclined struts are clamped between the double-limb columns and are connected through bolts, so that the connection is convenient; the beam ends and the joints of the beams and the inclined struts are reinforced, bamboo cross grains are prevented from being pulled, and the bearing capacity is improved.

Description

technical field [0001] The invention belongs to the field of construction, in particular to a beam-column joint of a bamboo laminated wood frame structure. Background technique [0002] The area of ​​bamboo forest resources in my country ranks first in the world, but the utilization rate of bamboo is very low, and the resources have not been efficiently and rationally utilized. Raw bamboo that has not been further processed has poor anti-corrosion, fire-proof, and mildew-resistant properties, and its size is irregular. It is inconvenient to connect when used as a building component, and cannot be widely used in modern construction projects. Bamboo treated by modern processing technology overcomes the shortcomings of natural bamboo, such as bamboo glulam, which is made of natural bamboo through cutting, cutting, cooking, dipping, drying, carbonization, gluing, side pressing and other processes to make about 20mm ×3mm bamboo slices, and pressed into integrated bamboo boards, ...

AI Technical Summary

Problems solved by technology

[0004] Beam-column joints of wood frame structures are generally connected by steel pins and bolts, which are hinged connections and cannot resist bending moments and horizontal loads. Usually, a separate structure to resist horizontal loads is required, such as using wood shear walls or wood supports. The wall is covered with wooden boards on the surface of the wooden keel and connected with nails to form a wooden wall. Wooden shear walls or wooden supports separate the building space and cannot form an open building space, which is inconvenient for the use of the building.
