Three-hole type energy absorber

Abstract

The invention relates to a three-hole type energy dissipater which comprises an upper connecting unit, a lower connecting unit and at least an energy dissipation plate. The upper connecting unit comprises an upper body extending in a first direction and fixedly arranged at the lower end of an upper structure body, and a first assembly part extending downwards from the upper body; the lower connecting unit comprises a lower body extending in the first direction and fixedly arranged at the upper end of a lower structure body, and a second assembly part extending upwards from the lower body; the first assembly part is not in direct contact with the second assembly part; the energy dissipation plate vertically extends to be a long shape, the plated surface of the energy dissipation plate is parallel with the first direction, one end of the energy dissipation plate is articulated with the corresponding first assembly part to form an upper end articulated part, and the two points different from the upper end articulated part are articulated with the second assembly part to form a middle articulated part and a lower end articulated part. The three-hole type energy dissipater has the advantages that the entire stress cross section can reach ultimate stress at the same time, the stress concentration cannot occur, the maximum energy can be absorbed, the installation method is more convenient and reliable, and the construction and the replacement are both more convenient; in addition, the integral plastic deformation of the energy dissipater can reach twice of that of the prior energy dissipater, and the energy dissipation ability is stronger.

Description

technical field [0001] The invention relates to an energy dissipation device, in particular to a three-hole type energy dissipation device with double-span energy dissipation plate parallel force design and improved shock absorption capacity. Background technique [0002] Installing energy-dissipating devices in buildings to absorb earthquake force and reduce the damage to the structure itself is the basic concept of shock-absorbing structures in the industry and academia. In the past ten years, a variety of methods to realize this concept have been developed, with various effects. different. For example, China Taiwan Patent Announcement No. 165491 "Earthquake Energy Dissipation Device", Announcement No. 227281 "Scissor Type Shock Absorbing Energy Dissipating Device", and Announcement No. 234444 "Pressure Type Shock Absorbing Energy Dissipating Device" patent case, roughly are like figure 1 As shown, it is a three-dimensional schematic diagram illustrating the structure of...

Problems solved by technology

[0004] However, the hinged end 11 of the former energy dissipation device is complicated to manufacture, and the fixed end 12 and the lower end of the energy dissipation plate 10 of the latter anti-seismic device are fixed by welding, and there is a problem that welding heat affects the physical properties. More importantly, Since the energy dissipation sheet is perpendicular to the force (earthquake force), when the construction is buried in a wall or column, the thickness of the wall or the width of the column needs to be increased according to the size of the sheet, which affects the indoor space

In addition, when the energy dissipation sheet is stressed, the degree of plastic deformation between the hinged end and the fixed end in the direction of the force is limited by its single-span design and height, so the ability to absorb shock and energy is also limited

[0005] It can be seen that the above-mentioned existing energy dissipation devices obviously still have inconvenience and defects in structure and use, and need to be further improved urgently

In order to solve the above-mentioned problems, the relevant manufacturers have tried their best to find a solution, but for a long time no suitable design has been developed, and the general products do not have a suitable structure to solve the above-mentioned problems. Urgent problem
