Abstract

The invention discloses a laminated wood latticed shell structure. A first overlap layer is formed by first laminated wood beams, a second overlap layer is formed by second laminated wood beams, thenthe first overlap layer is placed on the second overlap layer, and the first laminated wood beams and the second laminated wood beams are connected and fixed through high-strength screw set connectingparts arranged in order. In order to further improve the overall rigidity of the laminated wood latticed shell structure, reinforced laminated wood beams are arranged below the second laminated woodbeams in a manner of being aligned to the first laminated wood beams. Due to the fact that the wood beams are not on the same arc face, the wood beams are continuously connected in the connecting joint area, that is, each first laminated wood beam, each second laminated wood beam and each reinforced laminated wood beam are all intact in the extending direction and do not need to be broken in the connecting joint area. The problems that in the prior art, connecting of laminated wood beams is difficult in joint areas, rigidity is insufficient, steel plates are inserted internally to weaken the strength of the connecting joint area of the laminated wood beams, and the construction effect is poor after connecting parts are exposed by the joint area are solved.

Description

technical field [0001] The invention relates to the field of building structure design, in particular to a glued wood reticulated shell structure. Background technique [0002] The glulam structure has the advantages of light weight, green environmental protection, and convenient construction and installation. It can also realize assembly construction, which is very suitable for some buildings with special functions or buildings that require the effect of wood structure buildings. The glulam structural material is a renewable resource, and it is also in line with the general direction of green environmental protection and assembly installation in the field of architectural structure design. However, at present, almost all engineering cases of large-span space reticulated shells are steel structures or aluminum alloy structures, and structural engineering using glulam is rarely used. This is due to the fact that the material of the glulam structural material is not uniform, ...
