Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of building seismic design, and particularly relates to a building seismic connecting piece. BACKGROUND

[0002] The load-bearing system of a building is mainly a frame structure formed by beams and columns connected in a rigid or hinged manner. The frame formed by beams and columns jointly resists horizontal loads and vertical loads that occur during use. The walls of a house using a frame structure do not bear weight and only serve as a shelter and a partition. The beam-column joint plays a pivotal role and is the key to transmitting internal forces. Therefore, in the case of material aging or damage caused by external forces such as earthquakes, the beam-column joint needs to be reinforced and maintained to ensure the safety of the building.

[0003] The related technology is disclosed in Chinese Patent No. CN109537928B, which discloses a frame beam-column seismic reinforcement structure. A variable cross-section reinforcement section is extended outward below the frame beam adjacent to the frame column. A beam-end reinforcement channel steel plate is matched and surrounded at the position of the frame beam adjacent to the frame column, and is connected and fixed with the floor slab and the variable cross-section reinforcement section. The energy dissipation reinforcement member includes two arc-shaped shear steel plates that are perpendicular to each other. The lower ends of the two arc-shaped shear steel plates are connected by an angle steel part. The angle steel part is connected and fixed with a corresponding corner of the variable cross-section reinforcement section. The upper ends of the two arc-shaped shear steel plates are fixed with the beam-end reinforcement channel steel plate. A U-shaped buffer groove is bent at the middle position of each arc-shaped shear steel plate. The openings of every two adjacent U-shaped buffer grooves are oppositely arranged, and the two openings are tightly fixed with a composite elastic block by a fastening screw.

[0004] In view of the above related technology, the present applicant finds that this kind of seismic structure mainly increases the seismic reinforcement of the part of the floor slab close to the frame column, and the seismic reinforcement of the part of the floor slab away from the frame column is relatively limited. Especially for large-span frame structures (i.e. the distance between any two adjacent frame columns is greater than 7.8m), in order to increase the strength of the floor slab, the seismic reinforcement can only be supplemented by increasing the thickness of the floor slab, and thus needs to be improved. SUMMARY

[0005] The purpose of the present application is to provide a building seismic connecting piece which has the effect of supplementing the part of the floor slab away from the frame column.

[0006] The building seismic connecting piece provided by the present application adopts the following technical solution.

[0007] An anti-seismic connector for a building includes a lower connector, an upper connector, an arched support beam, and an arc-shaped support beam. At least two lower connectors are provided, each positioned on the upper end of any two adjacent columns. Two upper connectors are provided, both installed on the bottom surface of a floor slab. Two arc-shaped support beams are provided, with their upper and lower ends fixedly connected to the corresponding upper and lower connectors. The two arc-shaped support beams are located at both ends of the arched support beam, with both ends of the arched support beam connected to the lower ends of the two arc-shaped support beams. The middle portion of the arched support beam arches upwards and connects to the bottom surface of the floor slab.

[0008] Specifically, by utilizing the cooperation between the upper connecting seat, the lower connecting seat, and the arc-shaped support beam, the part of the shelf close to the frame column can be reinforced. By utilizing the arched support beams that cooperate with the arc-shaped support beams at both ends, the part of the shelf far from the frame column can be reinforced. Furthermore, when the arched support beam is impacted and stretches, the arched support beam will transfer the force to the arc-shaped support beam, allowing the arc-shaped support beam to bend and deform, thereby achieving the effect of energy dissipation and shock absorption. This prevents the arched support beam from directly transferring the force to the upper end of the frame column, ensuring the safety of the frame column.

[0009] Furthermore, the cross-section of the arched support beam is arranged in an "I" shape, and two first high-strength elastic rubber pads are provided on both ends of the arched support beam. The two first high-strength elastic rubber pads located at the same end of the arched support beam have their opposite sides connected to the two sides of the arched support beam, and their opposite sides are fixedly connected to the arc-shaped support beam.

[0010] Specifically, the first high-strength elastic rubber pad enables an elastic connection between the end of the arched support beam and the arc-shaped support beam. When the middle of the arched support beam is subjected to pressure, causing a change in the curvature of the arched support beam, the end of the arched support beam and the arc-shaped support beam can undergo a certain relative change through the first high-strength elastic rubber pad. During this period, the first high-strength elastic rubber pad can also play a role in energy dissipation and vibration reduction.

[0011] Furthermore, the lower end of the arc-shaped support beam is provided with a through-hole, and the end of the arched support beam passes through the through-hole to the arc-shaped support beam. The opposite sides of the two first high-strength elastic rubber pads at the same end of the arched support beam are respectively fixedly connected to the two vertical sides of the through-hole. The cross-section of the arc-shaped support beam is set in the shape of an "I". The inner wall of the through-hole is provided with a waist-shaped plate that fits against the opposite sides of the two first high-strength elastic rubber pads located at the same end of the arched support beam.

[0012] Specifically, by the penetrating hole, the arc-shaped support beam can be directly penetrated through the arc-shaped support beam, so that the arc-shaped support beam can be matched with the arc-shaped support beam by the first high-strength elastic rubber pad, and when the arc-shaped support beam is stretched to a large extent, the end of the arc-shaped support beam does not interfere with the end of the arc-shaped support beam, and the waist-shaped plate can increase the connection area between the arc-shaped support beam and the first high-strength elastic rubber pad, so that the connection between the two is more stable.

[0013] Further, two side connecting seats are further included, the two side connecting seats are respectively arranged on the two ends of the arc-shaped support beam, and the two side connecting seats are respectively fixedly connected with the side of the two frame columns arranged correspondingly, and the side connecting seat and the arc-shaped support beam are elastically connected by the second high-strength elastic rubber pad.

[0014] Specifically, in this way, the frame column can also directly support the arc-shaped support beam, so that when the arc-shaped support beam is stretched due to the stress on the middle part, the second high-strength elastic rubber pad can also assist the first high-strength elastic rubber pad to dissipate energy and reduce vibration, and at the same time, the pressure on the arc-shaped support beam is avoided from being completely transferred to the arc-shaped support beam, thereby reducing the working pressure of the arc-shaped support beam.

[0015] Further, the arc-shaped support beam includes a first segment and a second segment, the first segment is arranged in a quarter circular ring shape, and the second segment is provided with two ends and arranged on the two ends of the first segment, and the two second segments are arranged perpendicular to each other, when the two ends of the arc-shaped support beam are connected with the upper connecting seat and the side connecting seat respectively, the second segment arranged horizontally on the arc-shaped support beam is fixedly connected with the lower side of the upper connecting seat, and the second segment arranged vertically on the arc-shaped support beam is fixedly connected with the side of the side connecting seat away from the frame column.

[0016] Specifically, the arc-shaped support beam composed of the first segment and the second segment can ensure sufficient connection area with the upper connecting seat and the lower connecting seat, the first segment arranged in a quarter circular ring shape has a damping function and plays a main role in energy dissipation and vibration reduction, so that the arc-shaped support beam can support and dampen the part of the layer plate close to the frame column.

[0017] Further, the upper connecting seat includes an upper connecting plate and a first connecting plate, the first connecting plate is arranged in a plurality of pieces along the width direction of the upper connecting seat, and the upper side of each first connecting plate is integrally connected with the upper connecting plate, the upper side of the first segment on the upper end of the arc-shaped support beam is arranged with a plurality of second connecting plates arranged alternately with each first connecting plate, and a first high-strength elastic rubber sheet is fixedly arranged between any adjacent first connecting plate and second connecting plate.

[0018] Specifically, the first connecting plate and the second connecting plate arranged in multiple pieces can increase the connecting area between the upper connecting seat and the upper end of the arc-shaped supporting beam, so that the connection between the upper connecting seat and the upper end of the arc-shaped supporting beam is more stable, and the first high-strength elastic rubber piece can achieve elastic connection between the upper connecting seat and the arc-shaped supporting beam, and each first high-strength elastic rubber piece can play a role of energy dissipation and shock absorption when subjected to vibration impact.

[0019] Further, the lower connecting seat comprises a lower connecting plate and a third connecting plate, the third connecting plate is arranged in multiple pieces along the width direction of the lower connecting seat, and one vertical side of each third connecting plate is connected with the lower connecting plate as a whole, the first section of the arc-shaped supporting beam at the lower end is arranged with a plurality of fourth connecting plates arranged alternately with the third connecting plates on one side close to the frame column, and a second high-strength elastic rubber piece is fixedly arranged between any adjacent third connecting plate and fourth connecting plate.

[0020] Specifically, the third connecting plate and the fourth connecting plate arranged in multiple pieces can increase the connecting area between the lower connecting seat and the lower end of the arc-shaped supporting beam, so that the connection between the lower connecting seat and the lower end of the arc-shaped supporting beam is more stable, and the second high-strength elastic rubber piece can achieve elastic connection between the lower connecting seat and the arc-shaped supporting beam, and each second high-strength elastic rubber piece can play a role of energy dissipation and shock absorption when subjected to vibration impact.

[0021] Further, it further comprises a middle connecting seat, the middle connecting seat is installed on the bottom surface of the layer plate, the bottom of the middle connecting seat is provided with a connecting column penetrating through the middle of the arch-shaped connecting beam, the outer wall of the lower end of the connecting seat is provided with a limiting ring abutting against the bottom surface of the arch-shaped connecting beam, and the two side surfaces of the connecting seat are both provided with a third high-strength elastic rubber pad, and the opposite side surfaces of the two third high-strength elastic rubber pads are both connected with the arch-shaped connecting beam as a whole.

[0022] Specifically, the cooperation between the connecting seat and the limiting ring can achieve more stable and firm connection between the middle of the arch-shaped connecting beam and the bottom surface of the layer plate, the third high-strength elastic rubber pad can achieve elastic connection between the middle connecting seat and the arch-shaped supporting beam, and the third high-strength elastic rubber pad can also play a role of energy dissipation and shock absorption.

[0023] In summary, the present application has the following at least one beneficial technical effect:

[0024] 1. It can simultaneously elastically support the part of the layer plate close to the frame column and the part away from the frame column, and further improve the seismic performance of the building;

[0025] 2. When elastically supporting the part of the layer plate away from the frame column, the influence on the upper end of the frame column is small, effectively ensuring the safety of the frame column. BRIEF DESCRIPTION OF DRAWINGS
