Problems solved by technology

Traditional pure wood joints are prone to damage and loss at the force transmission intersection of columns and beams. Most of the current joints are pure steel member joints. By inserting steel sheets into the wood for connection, stress concentration is easy to occur, and along the Cracks along the grain are prone to occur in the opening direction; in addition, in order to ensure the basic force transmission of the beam, the force transmission section of the vertical column is often weakened, and there are cases of poor integrity and mechanical performance, and the seismic performance is weaker than other positions

Embodiment 1

[0043] Embodiment 1, a kind of circular sleeve steel-wood composite node, such as figure 1 with figure 2 As shown, it includes FRP circular wooden columns 1, X-shaped wooden beams 2, core connecting members 3, arc-shaped connectors 4 and spliced ​​outer ring plates 5; the upper and lower adjacent FRP circular wooden columns 1 pass through core connecting members 3 Connected, after the upper and lower adjacent FRP circular wooden columns 1 are connected, they are connected with the X-shaped wooden beam 2 through the arc connector 4, and finally the whole is fixed by splicing the outer ring plate 5;

[0044] Such as image 3 with 4As shown, they are the structural schematic diagrams of the FRP circular wooden column 1 and the X-shaped wooden beam 2 respectively, and the FRP circular wooden column 1 includes a circular wooden column 6 and an FRP fiber cloth 8 arranged on the outer surface of the circular wooden column 6 , by winding the FRP fiber cloth 8 on the outer layer to...

Embodiment 2

[0050] Embodiment 2. Based on the circular sleeve steel-wood composite node proposed in Embodiment 1, this embodiment proposes a method for its installation, such as Figure 17 As shown, the following steps are included. Of course, during the specific implementation, the following steps can be slightly changed according to the actual situation:

[0051] The first step is to set the round steel sleeve plate 9 on the FRP round wood column 1 that has been injected with glue, and there are pull bolts on the penetrating steel bars, and rotate the fan-shaped splicing joint of the connecting sleeve 10 with the round solid wood 11 inside for 45° Screw it into the docking slot on the corresponding side of the circular steel sleeve plate 9;

[0052] The second step is to fix the connecting sleeve 10 between the circular steel sleeve plates 9, fill in 4 filling blocks 12, and glue them together to form a whole;

[0053] The third step is to install the filling member 4 on the middle tai...

Abstract

The invention discloses a round sleeve steel-wood assembly node. The round sleeve steel-wood assembly node comprises an FRP round wood column, an X-shaped wood beam, a core connecting component, splicing outer ring plates and an arc-shaped connector, wherein the core connecting component consists of upper and lower round steel sleeve plates, a connecting sleeve, round solid wood, filling wood blocks, and the like; the FRP round wood column and the core connecting component are connected, are plugged through circular steel sleeve plates in a mode of penetrating through reinforcing steel bars, and are connected by injecting glue into gaps of the reinforcing steel bars; the X-shaped wood beam is connected to the core connecting component through the arc-shaped connector; and the splicing outer ring plates and bolts are fixed to realize assembly connection. According to the scheme adopted by the invention, the node structure adopts a connecting sleeve design, so that bearing force is high,vertical force transmission is guaranteed to be free of influences, and a horizontal force transmission way and a vertical force transmission way are not crossed; during field construction mounting,glue connection and glue bonding are adopted, so that operation is simple, mounting is quick, assembly type mounting is complete, and design requirements of a wood structure building with special vertical load can be met, and therefore, the round sleeve steel-wood assembly node has great market potential in a medium and high-rise wood building.

Description

technical field [0001] The invention belongs to the field of wooden building node design, in particular to a circular sleeve steel-wood composite node connected with a circular wooden column and an X-shaped wooden beam and an installation method thereof. Background technique [0002] In the field of modern architecture that pays attention to environmental protection, wood structure building, as a green and environmentally friendly building with low energy consumption and light materials, has great application potential and research value. The wooden structure has the characteristics of short construction period, energy saving and environmental protection, and strong earthquake resistance and energy consumption. In terms of design, it has the advantages of flexible layout, sound insulation and shock reduction. [0003] However, in a wooden structure building, the joint is one of the most important areas in the whole structure. Traditional pure wood joints are prone to damage...
