Bamboo (wood) frame structure beam column assembly type energy consumption joint

Abstract

The invention discloses a bamboo (wood) frame structure beam column assembly type energy consumption joint. The assembly type energy consumption joint is installed in the connection position of a column and a beam and comprises a cross-shaped steel column, a horizontal reinforcing steel plate, column connecting steel plates, beam flange steel plates and a beam connecting steel plate. The horizontal reinforcing steel plate used for preventing compressive buckling of column limbs is welded to the middle of the cross-shaped steel column. One column limb of the cross-shaped steel column is wide and serves as a beam web. The column connecting steel plates are welded to the upper end and the lower end of the cross-shaped steel column correspondingly. The beam connecting steel plate is welded to the end of the wide column limb which serves as the beam web. The beam flange steel plates are welded to the upper portion and the lower portion of the wide column limb correspondingly. One end of each beam flange steel plate is welded to the corresponding column connecting steel plate, and the other end of each beam flange steel plate is welded to the beam connecting steel plate. The bamboo (wood) frame structure beam column assembly type energy consumption joint is reliable in connection and convenient to construct, has a certain energy consumption capability and has high bearing capacity.

Description

Technical field [0001] The invention relates to an energy consumption node, in particular to a bamboo (wood) frame structure beam-column assembly type energy consumption node, which belongs to the field of civil engineering. Background technique [0002] At present, due to the characteristics of their own materials, bamboo and wood structures can only be constructed using fabricated structures. As bamboo (wood) materials exhibit obvious brittleness when under tension, it is more important to consume seismic energy through bending and deformation of the materials. Difficult, so the only way to consume seismic energy is through node deformation. [0003] The existing bamboo (wood) frame structure beam-column fabricated joints mainly have the following forms: ① Tenon-and-mortise connection, which is the oldest wooden structure connection method, has good artistic quality, but the connection stiffness of the joint is relatively high. Low, poor energy consumption, and, due to the large...

AI Technical Summary

Problems solved by technology

[0002] At present, bamboo and wood structures can only be constructed using prefabricated structures due to their own material characteristics. Since bamboo (wood) materials show obvious brittle characteristics when they are under tension, it is relatively difficult to consume seismic energy through bending deformation of materials. Difficult, so the seismic energy can only be dissipated through the deformation of the nodes

[0003] The existing bamboo (wood) frame structure beam-column assembled joints mainly have the following forms: ① Mortise and tenon connection, which is the oldest wood structure connection method, has good artistry, but the connection stiffness of the joint is relatively low. Low energy dissipation capacity, and, due to the large weakening of the cross section of the node area, the bearing capacity of the node is low, which is not conducive to the use in high-rise structures

② Reinforcement method, the beam-column members are connected through the form of rebar. This connection form is relatively reliable, but the site construction space requires a lot. When there are beam-column connections in two directions on the plane, the construction is inconvenient and the quality is not good. It is easy to ensure, and the energy dissipation capacity is limited; ③The embedded steel plate bolt connection is a node form in which the bamboo (wood) components are slotted, embedded with steel plates, and fixed with bolts. The brittle failure characteristics of this connection method are compared with Obviously, the energy dissipation capacity is average. When the beams and columns in two directions are connected at the same time, the construction is more difficult

[0004] In summary, the existing bamboo (wood) beam-column assembled energy-dissipating nodes have shortcomings such as weak connection, inconvenient construction, and weak bearing capacity.
