Background
The wood has the advantages of light weight, recoverability, low pollution and the like, so the wood is particularly in line with the spirit of sustainable development and is particularly suitable for areas with frequent earthquakes, and therefore, the wood building plays a significant role in the future building design trend. With the development of engineering wood products and processing technologies, modern wood structure buildings are not limited to the construction of small houses any more, but are increasingly applied to large-scale structures such as large spans, high-rise buildings and the like, and long members such as basic members such as overlong beams, columns, arches and the like are commonly used in the large-scale structures. The node is the basis for the continuity of the structure and the reason for the modeling, and is particularly important in the wood structure building.
The laminated wood member is used as a common structural member of the existing wood structure building, can be used for large-scale public buildings with large volume and large span, and has the advantages of simple structure, convenient manufacture and higher strength and fire resistance limit. The wooden member nodes of modern glued wood structures usually take the form of connecting nodes with embedded steel plate bolts, and usually consist of connected wooden members, filled steel plates and bolts. The bearing capacity of the common bolt-steel filler plate node is restricted by the lower tensile strength of the cross grain of the laminated wood timber, and under the action of internal forces such as bending moment and the like, the contact part of the bolt and the wood member can form higher cross grain tensile stress, so that the node is subjected to cross grain fracture early and becomes a middle and weak part of the structure. Therefore, for a large-span space wood structure, a connection node with high bearing capacity and rigidity needs to be developed.

Compared with the prior art, the invention has the following advantages:
1. according to the invention, through the matching arrangement of the inner filling plate and the side panel, the inner filling plate can effectively transfer the acting force between the first wood member and the first wood member, the side panel provides transverse restraint for the wood in the node area, the tensile strength of the wood in the cross grain direction of the node area is obviously improved, the cross grain fracture damage which is easy to occur when the node is bent is effectively improved, the premature cross grain fracture damage of the node is avoided, the stability and the bearing capacity of the node are increased, and the method can be used for splicing the glued wood beam and splicing new wood for replacing the damaged part of the wood member and old wood of the undamaged part of the wood member;
2. the two connecting pieces are simple in structure, convenient to process and manufacture, capable of being installed separately, connected through the bolts, convenient to construct and install, simple and effective;
3. the joint of the inner filling plate and the side panel deviates from the middle position of the side panel, so that the inner filling plate of the upper connecting piece and the inner filling plate of the lower connecting piece can be prevented from being interfered with each other in the inserting process, and the inner filling plate of the lower connecting piece are staggered, and are convenient to insert and position quickly;
4. the invention has simple structure and less required parts, and can reduce the load of the extension node of the glued wood beam;
5. according to the invention, the side panels respectively coat the upper side and the lower side of the joint of the first wood component and the second wood component, so that the first wood component and the second wood component can be prevented from being separated under the action of vertical load or gravity, and the side panels are more suitable for a large-span space wood beam structure;
