Description

Technical Field

[0001] The utility model relates to the technical field of building energy dissipation and shock absorption, in particular to a position limiting buffer device. Background Art

[0002] During the construction of buildings and bridges, dampers or vibration buffers are usually installed in the building to dissipate the energy brought by external vibrations, so as to avoid damage and cracks in the building due to earthquakes or vibrations, which poses a hidden danger. However, the existing damper can only bear the forces at both ends of itself, that is, it can only dissipate the forces in a single direction, and cannot effectively dissipate the forces perpendicular to the damper. Conventional dampers have a deformation segment for dissipating energy and a connection portion for connecting to the building at both ends of the deformation segment. In order to deal with the above problems, the prior art generally adopts a method of using a pin shaft and a universal hinge between the deformation segment and the connection portions at both ends to solve the problem, or adopts a method of leaving a lateral gap between the deformation segment and the connection portion to solve the problem. However, due to the structure of the damper itself, these methods can only deal with the situation where the deformation amount perpendicular to the damper is very small, and cannot effectively deal with the large displacement caused by the large lateral impact force, which may cause the damper to become lateral unstable or break, posing a safety hazard to the building.

[0058] When the position limiting buffer device is used, the first buffer member 2 of suitable material is first selected and sleeved on the first guide rod 23 and the second guide rod 24 one by one, the first guide rod 23 is aligned with the opening of the first guide groove 33 away from the first baffle 37, the second guide rod 24 is aligned with the opening of the second guide groove 34 away from the first baffle, and then the second part is pushed toward the first part until the ends of the first guide rod 23 and the second guide rod 24 are completely located in the first guide groove 33 and the second guide groove 34. At this time, the first transverse buffer member 21 is located between the second plate structure 13 and the first abutting portion 35 and the second abutting portion 36, and the second transverse buffer member 22 is located between the third plate structure 14 and the first abutting portion 35 and the second abutting portion 36.

[0059] There is a gap between the lower end surface of the first plate structure 11 and the upper end surfaces of the second plate structure 13 and the third plate structure 14, and the gap is not less than the sum of the distances between the first guide rod 23 and the upper and lower walls of the first guide groove 33, and similarly, it is not less than the sum of the distances between the second guide rod 24 and the upper and lower walls of the second guide groove 34. In this way, vertical displacement space can be reserved for the first guide rod 23 and the second guide rod 24, avoiding friction between the first guide rod 23 and the second guide rod 24 and the first guide groove 33 and the second guide groove 34, which not only causes the first guide rod 23, the second guide rod 24 and the first limiting member 3 to wear, but also reduces the vibration buffering capacity of the device due to excessive friction. At the same time, when the device as a whole is subjected to vertical vibration, it can also release the rotational force generated by the movable ends of the upper support column and the movable ends of the lower support column rotating outward from the original vertical axis.

[0060] A plurality of the first embedded rods 41 are embedded in the upper support column to fix the first plate structure 11 to the lower end of the upper support column, and a plurality of the second embedded rods 42 are embedded in the lower support column to fix the sixth plate structure 12 to the upper end of the lower support column at a position corresponding to the first plate structure 11. During installation, the length direction of the first limiting member 3 should be perpendicular to the length direction of the damper so that it can buffer vibrations in a direction perpendicular to the damper to prevent the damper from becoming unstable or breaking.

[0061] When the building encounters horizontal vibration, the first part and the second part move relative to each other in the horizontal direction. Such movement will compress the first transverse buffer 21 or the second transverse buffer 22 to play a role in vibration buffering, reducing the relative movement amplitude of the upper support column and the lower support column, thereby protecting the damper and making the overall stability of the building stronger.

[0062] The working method of the second embodiment of the position limiting buffer device of the present utility model is as follows: firstly, the second buffer member 6 of suitable material is selected and sleeved on the third guide rod 63 and the fourth guide rod 64 one by one, the third guide rod 63 is aligned with the opening of the third guide groove 73 away from the second baffle 77, the fourth guide rod 64 is aligned with the opening of the fourth guide groove 74 away from the second baffle 77, and then the second part is pushed toward the first part until the ends of the third guide rod 63 and the fourth guide rod 64 are completely located in the third guide groove 73 and the fourth guide groove 74. At this time, the first longitudinal buffer member 61 is located between the fourth plate structure 51 and the third abutting portion 75 and the fourth abutting portion 76, and the second longitudinal buffer member 62 is located between the fifth plate structure 52 and the third abutting portion 75 and the fourth abutting portion 76.

[0063] The first embedded rods 41 are embedded in the upper support column to fix the first plate structure 11 to the lower end of the upper support column, and the second embedded rods 42 are embedded in the lower support column to fix the sixth plate structure 12 to the upper end of the lower support column at a position corresponding to the first plate structure 11. During installation, the length direction of the second limiting member 7 should be horizontal to the length direction of the damper, so that it can buffer the vibration in the direction of the horizontal damper, disperse the force borne by the damper, and avoid the damper being too stressed and unstable.

[0064] When the building encounters horizontal vibration, the first part and the second part move relative to each other in the horizontal direction. Such movement will compress the first longitudinal buffer 61 or the second longitudinal buffer 62 to play a role in vibration buffering, reducing the relative movement amplitude of the upper support column and the lower support column, thereby protecting the damper and making the overall stability of the building stronger.
