Description

Technical Field

[0001] The invention belongs to the field of civil engineering building structures, and in particular relates to a detachable wood-bamboo component energy dissipation connection node and an assembly method. Background Art

[0002] With the rapid development of my country's traditional construction industry, problems such as resource shortage, energy waste and environmental degradation have emerged. In order to solve these problems, more and more attention has shifted to various bamboo and wood structure buildings. However, due to the long growth cycle of wood, my country's bamboo resources are rich and the growth cycle of bamboo is short. The growth cycle of raw bamboo is only 3-4 years, which meets the requirements of sustainable development. In addition, bamboo is light, elastic and has excellent seismic performance. Therefore, bamboo as a new green and environmentally friendly material has received more and more attention in the construction industry.

[0003] However, the overall performance of bamboo in building structures, such as strength, stiffness, stability, and durability, depends largely on the connections between the components of the structure. Nodes are the key to ensuring the transfer of structural loads and the overall stress of the structure. Their failure and damage may lead to the overall collapse of the building structure. Therefore, node design is one of the core of building structure design. Traditional binding nodes and mortise and tenon nodes have the disadvantages of insufficient stiffness and low ductility. They are prone to brittle failure under earthquakes, endangering the safety of the overall structure, and therefore cannot meet the seismic performance requirements of modern buildings. Summary of the invention

[0004] In order to solve the above technical problems, the present invention proposes a detachable wood-bamboo component energy dissipation connection node and assembly method, which has the advantages of flexible use, reliable connection, convenient installation, and certain energy dissipation and shock absorption capabilities.

[0005] The technical solution adopted by the present invention is as follows

The FRP in the steel plate (6) and the square FRP steel sleeve (9) are all covered on the surface; the T-shaped FRP steel plate (6) thickened in the middle and the two fan-shaped viscoelastic dampers (8) are connected and fixed to the square FRP steel bottom plate (3) with the reserved threaded rods through the reserved threaded rods and the hexagonal FRP steel nuts (4); the high-strength viscoelastic damper (7), the two fan-shaped viscoelastic dampers (8) and the square FRP steel sleeve (9) are connected through the corresponding reserved bolt holes and the high-strength hexagonal FRP steel bolts (5) to form a sleeve damper bottom plate integrated part; during assembly, the sleeve damper bottom plate integrated part and the square FRP steel bottom plate (2) are connected on the six faces of the cubic hollow FRP metal block (1) through the high-strength hexagonal FRP steel bolts (5); when a component in the combined node is damaged, it can be easily disassembled and replaced.

[0007] The FRP is a high-strength fiber material (FRP), which can be one or more combinations of carbon fiber, basalt fiber, glass fiber, aramid fiber, etc.

[0008] The square FRP steel bottom plate (2) has 4 holes, the square FRP steel bottom plate (3) with reserved threaded rods has 14 holes, and the holes on each bottom plate are symmetrically distributed.

[0009] The protruding portion of the middle thickened T-shaped FRP steel plate (6) is thickened and a through hole corresponding to the bolt hole reserved at the bottom of the high-strength viscoelastic damper (7) is reserved, and the FRP is attached to the surface of the steel.

[0010] The bottom of the square FRP steel sleeve (9) is provided with a groove of a size corresponding to the upper part of the high-strength viscoelastic damper (7) and bolt holes at corresponding positions. The four faces of the square FRP steel sleeve (9) and the corresponding positions of the square wood-bamboo beams (10) are also provided with reserved bolt holes so that the square wood-bamboo beams (10) inserted therein can be fixed with high-strength hexagonal FRP steel bolts (5).

[0011] Furthermore, bolt holes corresponding to the reserved through holes of the cubic hollow FRP metal block (1) are reserved at the four corners of the square FRP steel bottom plate (2). The square FRP steel bottom plate (2) and the square FRP steel bottom plate (3) with reserved threaded rods are available in three different sizes and correspond to each other.

[0014] The beneficial effects of the present invention are as follows: all the components of the node can be prefabricated in a factory, and have the advantages of low difficulty in on-site construction and installation and fast molding, and can be applied in various complex marine environments. At the same time, according to actual needs, the six faces of the central cube FRP metal block can be flexibly selected to connect the sleeve damper FRP steel plate integral part or the corresponding square FRP steel bottom plate, and have the advantages of flexible use, diverse functions and wide application. At the same time, due to the addition of high-strength viscoelastic dampers and fan-shaped viscoelastic dampers in the node, the reciprocating shearing of the viscoelastic material can consume energy, so the node also has a certain shock-absorbing and energy-dissipating function.
