Description

Technical Field

[0001] The utility model relates to the technical field related to construction equipment, and in particular to an anti-seismic support for construction. Background Art

[0002] Many construction projects have adopted effective earthquake-resistant measures such as combining rigidity and flexibility, and used earthquake-resistant bearings for seismic isolation. The seismic response of the superstructure is reduced by installing isolation devices between the superstructure and the lower support system.

[0003] For example, patent publication number CN219638156U provides a seismic bearing for buildings, which includes a lower seismic support plate and an upper seismic support plate. A longitudinal support column is fixedly mounted at the center of the lower seismic support plate. A longitudinal seismic sleeve is slidably mounted on the upper end of the longitudinal support column. The upper end of the longitudinal seismic sleeve is fixedly connected to the upper seismic support plate. Arched support frames are mounted on the sides of the longitudinal support columns, and the upper end of the arched support frames is connected to the transverse seismic seat. This seismic bearing utilizes the longitudinal support column for longitudinal support, and in conjunction with the longitudinal seismic sleeve and longitudinal damping spring, it provides excellent longitudinal seismic resistance. The arched support frame, in conjunction with the transverse seismic seat, also provides excellent transverse seismic resistance.

[0004] Based on the above search and in combination with existing technologies, it was found that existing anti-seismic bearings for buildings similar to those disclosed above have poor adjustability and require a cement layer to be applied for leveling before or after installation, which is a relatively cumbersome operation. Therefore, a new anti-seismic bearing for buildings is proposed to improve the above-mentioned problem. Utility Model Content

[0005] The purpose of this application is to provide a seismic bearing for buildings to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned objectives, the present application provides the following technical solutions: a seismic support for a building, comprising an upper seismic support, a seismic pillar, and a lower seismic support plate fixed in sequence from top to bottom, a fixing seat provided on the lower side of the lower seismic support plate, the fixing seat being connected to the buttress, a plurality of studs being vertically fixed to the upper end of the fixing seat, and a through hole provided on the lower seismic support plate for the studs to pass through, wherein the diameter of the through hole is larger than the diameter of the stud;

[0007] The stud is threadedly connected with a second nut and a first nut in sequence from top to bottom, and the second nut and the first nut are respectively pressed against the upper and lower sides of the lower anti-seismic support plate.

[0008] As a further supplement to this solution, a butt ring is rotatably installed on the upper end of the first nut. The butt ring is sleeved on the outside of the stud and butts against the bottom end of the lower seismic support plate.

[0009] As a further supplement to this solution, a casting retaining frame is sleeved on the outer side of the lower seismic support plate, and the inner wall of the casting retaining frame does not contact the lower seismic support plate.

[0010] As a further supplement to this solution, a connecting frame is fixed to the bottom end of the casting retaining frame, and the connecting frame is detachably connected to the fixing seat.

[0011] As a further supplement to this solution, a pouring port is provided at the side end of the casting retaining frame.

[0012] As a further supplement to this solution, mounting screw holes are vertically provided on the lower seismic support plate, and the seismic support column is formed by overlapping steel plate layers and rubber sheet layers and then vulcanizing them.

[0013] In summary, the technical effects and advantages of the utility model are:

[0014] 1. In the present invention, through the coordinated arrangement of the fixing base, the stud, the first nut and the second nut, during installation, for a pier with a non-horizontal upper surface, the fixing base can be fixed to the upper end surface of the pier with a bolt, and then the first nut is rotated to make multiple first nuts move up and down to adjust the lower seismic support plate, so that the upper end surface of the seismic support plate and the upper seismic support are horizontal, and finally the second nut is tightened so that the second nut is pressed against the lower seismic support plate, which makes installation more convenient.

[0015] 2. In the present invention, by setting up a casting retaining frame, after adjusting the upper end surfaces of the seismic support plate and the upper seismic support to be horizontal, the casting retaining frame is put on the outer side of the lower seismic support plate, and the connecting frame and the fixed seat are fixed with bolts. Mud is poured from the pouring port toward the inner side of the casting retaining frame, so that the mud fills the gap between the fixed seat and the lower seismic support plate. After the casting is completed, a sealed support body is formed to ensure the strength of the building. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example: Reference Figure 1-4 The seismic bearing for a building shown in the figure includes an upper seismic support 3, a seismic pillar 4 and a lower seismic support plate 2 fixed in sequence from top to bottom. The seismic pillar 4 is made of steel plate layers and rubber sheet layers overlapped and vulcanized, which provides sufficient longitudinal bearing capacity while also having great horizontal deformation capacity.

[0024] Among them, a fixing seat 5 is provided on the lower side of the lower seismic support plate 2, and the fixing seat 5 is connected to the pier 1. A plurality of studs 6 are vertically fixed to the upper end of the fixing seat 5. A through hole for the stud 6 to pass through is provided on the lower seismic support plate 2, and the aperture of the through hole is larger than the diameter of the stud 6. The second nut 8 and the first nut 7 are threadedly connected on the stud 6 from top to bottom in sequence, and the second nut 8 and the first nut 7 are respectively pressed against the upper and lower sides of the lower seismic support plate 2.

[0025] Based on the coordination setting of the above structure, during installation, for the pier 1 whose upper surface is not horizontal, the fixing seat 5 can be fixed to the upper end surface of the pier 1 with bolts, and then the first nut 7 is rotated to make multiple first nuts 7 move up and down to adjust the lower seismic support plate 2, so that the upper end surfaces of the seismic support plate 2 and the upper seismic support 3 are horizontal, and finally the second nut 8 is tightened so that the second nut 8 is pressed against the lower seismic support plate 2.

[0026] Among them, a resisting ring 9 is rotatably installed on the upper end of the first nut 7. The resisting ring 9 is sleeved on the outside of the stud 6 and resists the bottom end of the lower seismic support plate 2. When the first nut 7 is rotated, the resisting ring 9 always remains stationary with the lower seismic support plate 2 to prevent the first nut 7 from directly rubbing the lower seismic support plate 2.

[0027] Among them, a casting retaining frame 10 is provided on the outer side of the lower seismic support plate 2, and the inner wall of the casting retaining frame 10 does not contact the lower seismic support plate 2. A connecting frame 11 is fixed to the bottom end of the casting retaining frame 10, and the connecting frame 11 is detachably connected to the fixing seat 5. A pouring port 12 is provided at the side end of the casting retaining frame 10.

[0028] After adjusting the upper end surfaces of the seismic support plate 2 and the upper seismic support 3 to be horizontal, the casting retaining frame 10 is put on the outside of the lower seismic support plate 2, and the connecting frame 11 is fixed to the fixing seat 5 with bolts, and mud is poured from the pouring port 12 toward the inside of the casting retaining frame 10 so that the mud fills the gap between the fixing seat 5 and the lower seismic support plate 2. After the casting is completed, a sealed support body 13 is formed to ensure the strength of the building.

[0029] In addition, mounting screw holes are vertically provided on the lower seismic support plate 2. After casting is completed, long bolts can be used to drive into the sealing support body 13 through the mounting screw holes, and cooperate with the existing nut structure to further improve the overall connection strength of the seismic support.

[0030] The working principle of the present invention is as follows: during installation, for the pier 1 with a non-horizontal upper surface, the fixing seat 5 can be fixed to the upper end surface of the pier 1 by means of bolts, and then the first nut 7 is rotated so that the multiple first nuts 7 move up and down to adjust the lower seismic support plate 2 so that the upper end surfaces of the seismic support plate 2 and the upper seismic support 3 are horizontal, and finally the second nut 8 is tightened so that the second nut 8 is pressed against the lower seismic support plate 2; after adjusting the upper end surfaces of the seismic support plate 2 and the upper seismic support 3 to be horizontal, the casting retaining frame 10 is sleeved on the outer side of the lower seismic support plate 2, and the connecting frame 11 is fixed to the fixing seat 5 by means of bolts, and mud is poured from the pouring port 12 toward the inner side of the casting retaining frame 10 so that the mud fills the gap between the fixing seat 5 and the lower seismic support plate 2. After the casting is completed, a sealing support body 13 is formed, and then the casting retaining frame 10 is removed, and a long bolt is driven into the sealing support body 13 through the mounting screw hole, and the existing nut structure is used to further improve the overall connection strength of the seismic support.
