Example Embodiment

[0030] Example 1:

[0031] This embodiment provides a beam-column joint of bamboo and wood structure, including a joint main body 1, and the joint main body 1 has at least two branches to connect different numbers of columns and beams; Install bamboo-wood components, bamboo-wood components and node main body 1 constitute beam-column nodes.

[0032] Taking the connection of 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 arranged in the first branch, a second channel 3 is arranged in the second branch, and a third channel 4 is arranged 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 second channel 3 and the third channel 4 ar...

Example Embodiment

[0046] Embodiment 2:

[0047] The present 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 the cross-sectional dimensions of beams and columns according to actual needs.

[0049] Step 2: Prefab as figure 2 The bamboo-wood components shown, the bamboo-wood components can be machined by machine-cut tiger chakras and buttresses through mold processing, and the angle between the insert bars and the bamboo-wood components is about 45°.

[0050] The buttress is a section of the matching portion 11 away from the supporting portion 10 .

[0051] Step 3: Insert each bamboo and wood component into the corresponding channel respectively, and connect the upper column, lower column and beam to the node main body 1 by bolts.

[0052] Step 4: Inject the grouting material from the grouting hole 5 under pressure until the grouting hole...

Abstract

The invention discloses a bamboo-wood structure beam-column joint and method, and relates to the technical field of civil construction, the bamboo-wood structure beam-column joint comprises a joint main body, the joint main body comprises at least two channels communicated with each other, and each channel is provided with a bamboo-wood component; the bamboo-wood component comprises a supporting part and a supporting part which are connected into a whole, one channel is provided with a grouting hole corresponding to the supporting part, and the other channels are provided with slurry discharging holes corresponding to the supporting part. The joint main body and the bamboo-wood structure are cooperatively stressed, so that the connection performance of a beam-column joint area is improved, and the anti-seismic capacity requirement is met.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a beam-column node of a bamboo-wood structure and a method thereof. Background technique [0002] At present, the commonly used methods of beam-column connection in bamboo-wood structure mainly include tooth connection, pin connection, and tooth-plate connection. When these connection methods are used, the structure of bamboo and wood itself needs to be destroyed, and the bearing capacity of the beam-column joint area is reduced, which leads to the construction The overall seismic bearing capacity is rapidly reduced. [0003] Based on the damage degree of components under earthquake action, the bearing capacity of beam-column joints is required to be higher than that of other parts. However, the existing connection methods of bamboo and wood structures cannot improve the seismic capacity of the beam-column connection joints, and do not meet the requirements of strong j...
