Embodiment 1
[0031] This embodiment provides a bamboo-wood structure beam-column node, including a node body 1, the node body 1 has at least two branches to connect different numbers of columns and beams; the branches are provided with interconnected passages, each passage The bamboo and wood components are installed, and the bamboo and wood components and the node main body 1 form a beam-column node.
[0032] Taking connecting the upper column, the lower column and the beam as an example, the corresponding node body 1 has three branches as an example, namely the first branch, the second branch and the third branch, and the three branches form a T-shaped structure; figure 1 As shown, a first channel 2 is provided in the first branch, a second channel 3 is provided in the second branch, and a third channel 4 is provided in the third branch.
[0033] In this embodiment, the node body 1 adopts a sleeve structure, such as a steel sleeve.
[0034] The inner walls of the first channel 2 , the s...
Embodiment 2
[0047] This embodiment provides a construction method for a beam-column joint of a bamboo-wood structure, comprising the following steps:
[0048] Step 1: Use 3D software (such as finite element software) to determine beam and column section dimensions according to actual needs.
[0049] Step 2: Prefab as figure 2 For the bamboo and wood components shown, the bamboo and wood components can be machine-cut and made of tigers and buttresses through mold processing, and the angle between the inserted ribs and the bamboo and wood components is about 45°.
[0050] Wherein, the abutment is a section of the fitting part 11 away from the supporting part 10 .
[0051] Step 3: Insert each bamboo and wood member into the corresponding channel, and connect the upper column, lower column and beam with the node main body 1 through bolts.
[0052] Step 4: Pressure inject the grouting material from the grouting hole 5 until the grouting hole in the beam area (the first grouting hole 6) is d...
