Description

Technical Field

[0001] The invention relates to the field of energy dissipation and self-centering, and in particular to a horizontal wall connector device based on friction energy dissipation and self-centering. Background Art

[0002] At present, the dampers and self-centering systems of traditional wall horizontal connectors can only play a unilateral damping energy dissipation or a unilateral self-centering role. There are few devices that take into account both damping energy dissipation and self-centering systems. In addition, the energy dissipation capacity of traditional damper devices and the self-centering capacity of self-centering systems are usually fixed, and cannot be reasonably adjusted and arranged with the changes in time and space. They cannot adapt to the actual needs of various projects, have a narrow scope of use, large restrictions, single functions, and generally have complex structures, difficult maintenance, and high costs.

[0003] Patent No. CN113417379 A discloses a friction damper, in which a force-guiding device is provided in a cavity. The force-guiding device and the cavity have damping. The force-guiding device moves when impacted, thereby consuming energy. The disadvantage of this device is that the energy-consuming effect provided is small and only a single energy-consuming effect is provided, and self-centering is not provided.

[0004] Patent No. CN 213773924 U discloses an angular displacement friction damper, which dissipates energy through friction cooperation between an upper connecting hinge, a lower connecting hinge and a friction plate arranged on a support rod. The disadvantages of this device are that it has a small energy dissipation effect, has no self-centering system, and cannot be adjusted according to actual engineering.

[0005] In view of the above-mentioned situation, a device is proposed which has both damping energy dissipation effect and self-centering ability. The energy dissipation effect and self-centering ability of the device are not fixed, and can be replaced modularly according to the requirements of the use environment and bearing capacity to better meet the actual needs of various projects. The device has a simple structure, strong energy dissipation effect and self-centering ability, low cost, can be industrially mass-produced, easy to replace, and convenient to maintain. The device is a horizontal wall connector based on friction energy dissipation and self-centering. The working mechanism is that the spring provides self-centering ability and the friction damper provides energy dissipation effect to achieve the purpose of energy dissipation and self-centering, and has good application prospects. Summary of the invention

[0006] The purpose of the present invention is to provide a wall horizontal connector device based on friction energy dissipation and self-centering, so as to solve the limitation that the damper and self-centering system of the traditional wall horizontal connector can usually only play a unilateral damping energy dissipation role or a unilateral self-centering role, and cannot take both into account. In addition, the energy dissipation capacity of the traditional damper device and the self-centering capacity of the self-centering system are usually fixed, and cannot be reasonably adjusted and arranged with the changes of time and space, and cannot adapt to the actual needs of various projects. The structure is complex, the energy dissipation and self-centering capabilities are weak, the cost is high, and it cannot be mass-produced industrially, it is inconvenient to install, and it is difficult to maintain.

[0007] To achieve the above objectives, the present invention provides the following technical solutions: a horizontal wall connector device based on friction energy dissipation and self-centering, which includes a wall fixer, a friction damper and a spring from left to right, wherein the friction damper includes an outer H-shaped bracket, an inner H-shaped bracket, an upper friction steel plate, a lower friction steel plate, a friction aluminum plate, a pin shaft and a friction bolt.

[0008] The wall fixer is fixed to the wall as a whole by bolts passing through the reserved holes of the wall fixer. The wall fixer and the friction damper are connected to each other by inserting a pin shaft, and the friction damper can rotate freely through the pin shaft.

[0009] The outer H-shaped bracket flange plate of the friction damper is punched with holes, and the inner H-shaped bracket flange plate is punched with holes at the same position. The inner H-shaped bracket flange plate is between the outer H-shaped bracket flange plates. The outer H-shaped bracket and the inner H-shaped bracket are connected to each other by inserting a pin shaft. The two ends of the outer H-shaped bracket flange plate are each connected to an inner H-shaped bracket through a pin shaft, and the two ends of the inner H-shaped bracket flange plate are each connected to an outer H-shaped bracket through a pin shaft. Therefore, the outer H-shaped bracket and the inner H-shaped bracket are connected to each other to form a closed component that can be rotated by a pin shaft.

[0010] The upper friction steel sheet of the friction damper is punched with holes at both ends, the hole diameter at one end is slightly larger than the pin diameter, and the hole diameter at the other end is slightly larger than the friction bolt diameter. The lower friction steel sheet is punched with holes at both ends, the hole diameter at one end is slightly larger than the pin diameter, and a long hole is opened at one end so that the friction bolt can slide in the long hole. A round hole is opened in the middle of the friction aluminum sheet, and the hole diameter is slightly larger than the friction bolt diameter. A friction aluminum sheet is placed between the upper friction steel sheet and the lower friction steel sheet, and the upper friction steel sheet, the friction aluminum sheet and the lower friction steel sheet are tightened and fixed by the friction bolt to form a whole so as to apply friction force. The reserved holes of the upper friction steel sheet and the lower friction steel sheet at both ends of the whole are connected to the outer H-shaped bracket and the inner H-shaped bracket through the pin that is not inserted on the wall fixture to form a friction damper. Under the action of external force, the outer H-shaped bracket and the inner H-shaped bracket are compressed or stretched, so that the upper friction steel sheet, the friction aluminum sheet and the friction bolt slide relative to the lower friction steel sheet to consume energy.

[0011] The two ends of the spring are respectively connected to the friction damper through a pin shaft not inserted on the wall fixture, and the self-centering ability is provided by compressing the spring.

[0012] The number of the springs is not fixed and can be adjusted according to the actual force size of the project. The size of the upper friction steel plate, friction aluminum plate and lower friction steel plate and the tightness of the friction bolts are not fixed and can be adjusted according to the actual needs of the project.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The present invention overcomes the current situation that the traditional damper and self-centering system in the horizontal wall connection can only dissipate energy unilaterally or the self-centering effect cannot take both into account. By using the spring to provide the self-centering ability and the friction damper to provide the energy dissipation ability, a combination mechanism of damping and self-centering is realized, which can achieve good energy dissipation and self-centering effects.

[0015] 2. The present invention overcomes the problem that the size and capacity of general devices are fixed after they leave the factory and cannot be adjusted according to changes in the use environment and structure. By changing the number of springs, changing the contact surface sizes of the upper friction steel plate, the lower friction steel plate and the friction aluminum plate, and changing the tightness of the friction bolts, modular replacement can be achieved according to changes in the bearing capacity of the structure and the use environment, which is more conducive to application in various environments and structures.

[0016] 3. The present invention can overcome the shortcomings of the commonly used dampers and self-centering system devices of wall connectors, such as complex production process, high cost, difficulty in industrial production, short life, and difficulty in parts replacement, improve the damping energy dissipation effect and self-centering ability, and achieve the purpose of combining the two capabilities of damping and self-centering. At the same time, the device is convenient for replacing parts, has a long service life, is easy to industrialize, has a low cost, and is easy to use, which is conducive to its promotion.

Based on the embodiments of the present invention, all other embodiments obtained by other ordinary technicians in the field without making creative breakthroughs are within the scope of protection of the present invention.

[0024] Combination Figures 1 to 4 As shown, a wall horizontal connecting device based on friction energy dissipation and self-centering includes, from left to right, a wall fixer (1), a friction damper and a spring (8), wherein the friction damper includes an outer H-shaped bracket (2), an inner H-shaped bracket (3), an upper friction steel plate (6), a lower friction steel plate (10), a friction aluminum plate (7), a pin shaft (4) and a friction bolt (5).

[0025] In this embodiment, holes are formed at both ends of the upper friction steel sheet (6), the diameter of the hole at one end is slightly larger than the diameter of the pin shaft (4), and the diameter of the hole at the other end is slightly larger than the diameter of the friction bolt (5); a hole is formed in the middle of the friction aluminum sheet (7), and the diameter of the hole is slightly larger than the diameter of the friction bolt (5); holes are formed at both ends of the lower friction steel sheet (10), a long hole is formed at one end, the diameter of the long hole is slightly larger than the diameter of the friction bolt (5), and a round hole is formed at one end, the diameter of the round hole is slightly larger than the diameter of the pin shaft (4); the round hole at one end of the upper friction steel sheet (6), the round hole of the friction aluminum sheet (7) and the long hole of the lower friction steel sheet (10) are aligned, and the friction aluminum sheet (7) is located between the upper friction steel sheet (6) and the lower friction steel sheet (10); and the purpose of applying friction resistance is achieved by inserting the friction bolt (5) into the reserved hole and tightening the friction bolt (5). The other end circular hole of the upper friction steel sheet (6) is inserted into the pin shaft (4), and the other end circular hole of the lower friction steel sheet (10) is inserted into the pin shaft (4) so ​​as to be connected into a whole.

[0026] In this embodiment, holes are opened at both ends of the upper and lower flange plates of the outer H-shaped bracket (2), and the hole diameter is slightly larger than the diameter of the pin shaft (4). Holes are opened at both ends of the upper and lower flange plates of the inner H-shaped bracket (3), and the hole diameter is slightly larger than the diameter of the pin shaft (4). Since the web height of the outer H-shaped bracket (2) is greater than the web height of the inner H-shaped bracket (3), the flange plate of the inner H-shaped bracket (3) is located between the flange plates of the outer H-shaped bracket (2), one end of the upper friction steel plate (6) is placed between the inner H-shaped bracket (3), and the reserved holes of the outer H-shaped bracket (2), the inner H-shaped bracket (3) and the upper friction steel plate (6) are aligned.

Therefore, the outer H-shaped bracket (2) and the inner H-shaped bracket (3) are connected to each other to form a closed component that can be rotated by the pin shaft (4). Before the H-shaped bracket (2) and the inner H-shaped bracket (3) form a closed loop, the reserved hole at one end of the lower friction steel sheet (10) is placed in another pin shaft (4) at a position opposite to the pin shaft (4) connected to the upper friction steel sheet (6), and the lower friction steel sheet (10) is located between the inner H-shaped brackets (3), so that the outer H-shaped bracket (2), the inner H-shaped bracket (3), the upper friction steel sheet (6), the lower friction steel sheet (10), and the friction aluminum sheet (7) are connected to form a friction damper. The friction damper is connected to the wall fixture (1) to form a whole, and the wall fixture (1) is fixed to the wall by bolts.
