Of course, the connection node provided in the embodiment of the present invention can be applied to other wood structure rod system environments besides the glued wood beam structure, for example, the structures of the first wood member 101, the second wood member 102 and the third wood member 103 may be the same or different, all the wood members may also be wood column structures, and other applications are not described herein.

During the field construction, the nodes can be connected through the following processes: after the lower laminated wood beam (the third wood member 103) is installed and positioned, firstly, a stainless steel pin (the second positioning pin 202) is inserted, structural adhesive is injected into the fourth blind hole, the third blind hole in the middle laminated wood beam (the second wood member 102) is aligned to the second positioning pin 202 and spliced, positioning is completed, then, 4 high-strength full-thread galvanized screws (the second connecting member group) are driven, and the third wood member 103 and the second wood member 102 are fixedly connected. And then, inserting a stainless steel pin (a first positioning pin 201) into the second blind hole, driving structural adhesive into the second blind hole, aligning and splicing the first blind hole on the upper glued wood beam (the first wood member 101) with the first positioning pin 201, completing positioning, and then nailing 4 high-strength full-thread galvanized screws (a first connecting piece group) to complete the fixed connection of the second wood member 102 and the first wood member 101, so that the fixed connection of the connection nodes between the wood members is completed.

The diameter of the hole for mounting the connector, which is provided beforehand on the wood piece in this embodiment, is less than 5mm than the diameter of the corresponding connector. Namely the utility model provides a connected node realizes timber structure member or timber component at the accurate positioning of job site through using the stainless steel round pin of location between the timber component, the reliable biography power of structure member is undertaken to the connecting piece of rethread high-strength full thread galvanized screw or the above.

On the other hand, based on the same inventive concept, the utility model also provides a wooden space latticed shell structure, include: the inter-wooden-member connecting node as described above.

Therefore, the utility model provides a wooden space latticed shell structure is owing to include the above connecting node between the timber compoment, is guaranteeing on the basis of the atress performance of timber compoment node, improved site operation efficiency and precision, reduced the weakening of connecting node to timber compoment intensity and had good architectural appearance.

The above description is only for the preferred embodiment of the present invention, and does not limit the present invention. Any technical personnel who belongs to the technical field, in the scope that does not deviate from the technical scheme of the utility model, to the technical scheme and the technical content that the utility model discloses expose do the change such as the equivalent replacement of any form or modification, all belong to the content that does not break away from the technical scheme of the utility model, still belong to within the scope of protection of the utility model.
