AI Technical Summary
In traditional wooden structure assembly, after the beam and column are assembled, structural ring beams need to be arranged in separate parts of the floor slab, resulting in duplication of functions and waste of materials.
The connection between beam-column and beam-beam is achieved by dividing the structural beam into two assembled parts, one of which forms a frame with the columns, and the other part is arranged in a prefabricated floor slab. After the assembly of the floor slab and the frame, the two parts of the structural beam are combined into a whole to bear the load.
It reduces material waste, reduces overall cost, enhances the strength of tic toe beams and beam column nodes, and realizes structural simplicity and reliability.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of wood structure fittings, and particularly relates to a wood structure assembly insert connection node. Background Art
[0002] In traditional wood structure assembly, beam-column assembly connection is carried out first, and then floor installation is carried out. On the premise of existing structural beams, since the prefabricated floor is an independent component, it is necessary to arrange a structural ring beam. After the assembly of the structural ring beam and the structural beam, their functions are repeated, resulting in excessive safety redundancy and material waste. Content of the Utility Model
[0003] The purpose of the utility model is to provide a wood structure assembly insert connection node to solve the above problems. Through the form of inserts, the connection of beam-column and beam-beam is realized. From the perspective of cost control, the structural beam is divided into two assemblable parts. One part is used to form a frame with the column, and the other part is arranged in the precast floor to play the role of a structural ring beam. After the floor and the frame are assembled, the two parts of the structural beam are combined into a whole to bear the load during the building's service stage.
[0004] Technical Solution: The utility model provides a wood structure assembly insert connection node, including: a first insert and a second insert. A first groove is provided above the first insert, and a column connection part protrudes downward in the middle below the first insert. Through bolt holes are uniformly arranged on the first insert and the column connection part; a second groove matching with the first groove is provided in the middle below the second insert, and through bolt holes are uniformly arranged on the second insert. The second insert is connected with the first insert by mutual engagement of the first groove and the second groove. Both the first insert and the second insert are open below, and after the engagement connection, they form a grid beam as the connection node.
[0005] Further, for the above-mentioned wood structure assembly insert connection node, both the first insert and the second insert are integrally formed. This improves the strength of the insert and has a relatively low cost.
[0006] Further, for the above-mentioned wood structure assembly insert connection node, the first insert and the second insert have the same size.
[0007] Further, for the above-mentioned wood structure assembly insert connection node, the depth of the first groove is 1 / 2 of the height of the first insert, and the depth of the second groove is 1 / 2 of the height of the second insert. This enables the top surfaces of the first insert and the second insert to be flush, facilitating subsequent construction processes and simplifying other precast components.
[0008] Further, for the above-mentioned wood structure assembly insert connection node, the cross-sections of the first insert and the second insert are U-shaped.
[0009] Further, for the above-mentioned wood structure assembly insert connection node, the first insert and the second insert sandwich the cross beam and longitudinal beam of the wood structure building, and the column connection part is inserted into the top of the column, and bolts are driven in from the through bolt holes for fixed connection.
[0010] Further, for the above-mentioned wood structure assembly insert connection node, the width of the column connection part is the same as the cross-sectional width of the column.
[0011] As can be seen from the above technical solutions, the present utility model has the following beneficial effects: The wood structure assembly insert connection node described in the present utility model has a simple structure, reliable strength, and lower cost. The connection node is divided into two parts, and the strength redundancy of the connection node during the assembly of the frame can be distributed to the structural ring beam of the floor slab, reducing material waste and lowering the overall cost. The mutually engaging inserts strengthen the strength of the grid beam on the one hand and the strength of the beam-column joint on the other hand. Description of the Drawings

[0017] Embodiment 1
[0018] Such as Figures 1-3A wood structure assembly insert connection node as shown in the figure includes: a first insert 1 and a second insert 2. A first groove 11 is provided above the first insert 1, and a column connection part 12 protrudes downward in the middle below the first insert 1. Through bolt holes are evenly arranged on the first insert 1 and the column connection part 12. A second groove 21 that cooperates with the first groove 11 is provided in the middle below the second insert 2. Through bolt holes are evenly arranged on the second insert 2. The second insert 2 is connected to the first insert 1 by mutual engagement through the first groove 11 and the second groove 21. Both the first insert 1 and the second insert 2 are open at the bottom. After the engagement connection, a grid beam is formed as the connection node. Dividing the connection node into two parts can distribute the strength redundancy of the connection node during the assembly of the frame to the structural ring beam of the floor slab, reducing material waste and lowering the overall cost. The mutually engaged inserts strengthen the strength of the grid beam on the one hand and the strength of the beam-column node on the other hand.
[0019] As Figures 2-3 For a wood structure assembly insert connection node as shown in the figure, the cross-sections of the first insert 1 and the second insert 2 are U-shaped.
[0020] Embodiment 2
[0021] Based on Embodiment 1, in this embodiment, as Figures 2-3 For a wood structure assembly insert connection node as shown in the figure, the first insert 1 and the second insert 2 are both integrally formed, and the first insert 1 and the second insert 2 have the same size. The depth of the first groove 11 is 1 / 2 of the height of the first insert 1, and the depth of the second groove 21 is 1 / 2 of the height of the second insert 2. This improves the strength of the inserts and has a relatively low cost. The sizes of the first groove 11 and the second groove 21 match, enabling the first insert 1 and the second insert 2 to be closely connected and improving the connection strength.
[0022] In this embodiment, a cross beam and a longitudinal beam of a wood structure building are clamped between the first insert 1 and the second insert 2. The column connection part 12 is inserted into the top of the column, and bolts are driven through the through bolt holes for fixed connection.
[0023] In this embodiment, the width of the column connection part 12 is the same as the cross-sectional width of the column.
