Description

Technical Field

[0001] The utility model belongs to the field of building structures, and particularly relates to a beam-column joint of a multi-storey and high-rise timber structure building. Background Art

[0002] The application of green building materials has an urgent social need. Wood is a renewable green building material, and a large amount of carbon dioxide is absorbed during its growth process. Therefore, modern timber structures are ecological and environmentally friendly prefabricated building systems, which have the characteristics of good performance, low energy consumption, short construction period, comfortable living, and high industrialization level, with great development potential and broad application prospects for green ecological timber structures.

[0003] As a traditional connection method for timber structures, the mortise and tenon joint has many advantages. However, from the perspective of modern industry, the mortise and tenon connection method is relatively simple and has low connection strength, and can only build low-rise timber structures. It is still very difficult to realize multi-storey and high-rise timber structures. At the mortise and tenon joint, due to the need for precise concave-convex combination, the stress area at this part is greatly weakened, making it more vulnerable than other connection methods. In addition, the precise manufacturing requirements for the mortise and tenon structure are relatively high. If the manufacturing is improper, it will lead to unstable structure and easy damage. Content of the Utility Model

[0004] Purpose of the utility model: Aiming at the problem of weak connection strength of the mortise and tenon joint of the timber structure, the utility model provides a beam-column joint of a multi-storey and high-rise timber structure building, which improves the strength, stability and ductility of the connection joint through the combination of mortise and tenon and metal parts, further improves the bearing capacity of the multi-storey and high-rise timber structure building, and enables the whole structure to have excellent seismic performance.

[0005] The technical solution adopted by the utility model: A beam-column joint of a multi-storey and high-rise timber structure building, including a wooden column member, a wooden beam member, a metal connecting piece, a perforated steel bar, a pin bolt and a through bolt;

[0006] The connection of the upper column and the lower column of the wooden column member is connected by a perforated steel bar in cooperation with a pin bolt and a through bolt. Among them, the upper column is connected by a pin bolt, and the lower column is connected by a through bolt; the wooden column member and the wooden beam member are connected by a metal connecting piece and a pin bolt, which is convenient for construction, and the implicit connection is more beneficial to fire protection;

[0007] The lower column of the wooden column member is provided with a circular tenon head at the top, and the upper column is provided with a circular mortise at the corresponding position, forming a set of mortise and tenon structures; a hole for accessing the perforated steel bar is opened at the connection end of the circular tenon head and the circular mortise; half of the perforated steel bar is inserted into the lower column, and the other half is used to connect the upper column. The perforated steel bar is staggered with bolt holes, and corresponding pin bolt holes one and bolt holes one are respectively provided on the upper column and the lower column, and are connected and fixed to the upper column and the lower column in cooperation with the pin bolt and the through bolt;

[0008] The metal connecting piece is formed by welding an end plate and a plug plate; bolt holes II are formed in the end plate, and the end plate is assembled around the wooden column member through corresponding through bolts and nuts; a pair of plug plates are arranged on the outer side of each end plate, and a pair of corresponding slots are arranged on the installation end face of the wooden beam member; pin bolt holes II are formed in the plug plate, and corresponding pin bolt holes III are formed in the wooden beam member, and the wooden beam member is hoisted and connected by matching through pin bolts.

[0009] Preferably, the materials of the wooden column member and the wooden beam member are laminated veneer lumber, laminated strand lumber, parallel strand lumber or laminated wood veneer lumber.

[0010] Preferably, there are four perforated steel bars.

[0011] Preferably, the plug plate is single-piece or multi-piece.

[0012] Preferably, to prevent temperature stress concentration, the plug plate adopts a sawtooth shape.

[0013] Beneficial effects: The joint of the utility model realizes the connection at the intersection of beams and columns in multi-storey and high-rise timber structures by using mortise and tenon structures in combination with perforated steel bars and metal connecting pieces, greatly improving the connection strength, bearing capacity and seismic resistance of the joint, making the structure more stable; adopting implicit connection is beneficial to fire prevention; and the assembled connection improves the construction efficiency and prefabrication degree.
