Description

Technical Field

[0001] The present application relates to the technical field of building construction, and in particular to an anti-seismic and shock-absorbing device for a building. Background Art

[0002] Steel-structured buildings are a new type of building system, breaking down the boundaries between the real estate, construction, and metallurgical industries to form a new industrial system. Compared to traditional concrete buildings, steel-structured buildings use steel plates or steel sections instead of reinforced concrete, resulting in higher strength and improved earthquake resistance. Furthermore, because components can be factory-fabricated and installed on-site, construction time is significantly reduced. The reusability of steel significantly reduces construction waste, contributing to a greener and more environmentally friendly environment.

[0003] With respect to the above-mentioned related technologies, the applicant has found that steel structure buildings mainly use light steel components as the building skeleton, and then adopt cast-in-place technology to form walls and floor slabs. Among them, two adjacent light steel components (i.e., longitudinal beams and transverse beams) are generally fixedly connected by welding or bolting. The use of this method will result in a lack of buffer space between the two adjacent light steel components. At the same time, the two adjacent light steel components are mainly fixed by welding points or bolts, and the fixed connection area is small, resulting in insufficient stability. As a result, the existing steel structure buildings have insufficient seismic resistance and shock absorption capabilities. As a result, steel structure buildings are currently mainly used in ground-floor buildings, which limits the application and development of steel structure buildings in high-rise buildings. Summary of the Invention

[0004] The purpose of this application is to provide a building earthquake-resistant and shock-absorbing device, which has the effect of improving the earthquake-resistant and shock-absorbing capabilities of steel-structured buildings.

[0005] This application provides a building anti-seismic and shock-absorbing device, which adopts the following technical solutions:

[0006] A building seismic and shock-absorbing device includes a horizontal beam and a longitudinal beam. Column-type elastic lead-viscous dampers are provided on two opposite sides of the longitudinal beam. The lower ends of the two column-type elastic lead-viscous dampers are fixedly connected to the upper end of the longitudinal beam, and the upper ends of the two column-type elastic lead-viscous dampers are fixedly connected to the two long sides of the horizontal beam. A high-strength elastic buffer is provided between the top surface of the longitudinal beam and the bottom surface of the horizontal beam.

[0007] Specifically, the use of high-strength elastic buffers can flexibly connect the horizontal beams and the longitudinal beams, so that when the building is affected by vibration, the high-strength elastic buffers can play a role in buffering and shock absorption. The use of column-type elastic lead-viscous dampers can apply a force in opposite directions to the horizontal beams and the longitudinal beams, so that the horizontal beams and the longitudinal beams can be stably connected together, and the connection strength between the two can be ensured. At the same time, the column-type elastic lead-viscous dampers can also play a buffering role and realize a weld-free connection relationship between the horizontal beams and the longitudinal beams.

[0008] Furthermore, a connecting sleeve is provided on the bottom surface of the crossbeam, and connecting seats are provided on both opposite sides of the connecting sleeve. The upper ends of the two columnar elastic lead-viscous dampers are fixedly connected to the two connecting seats respectively, and the upper end of the longitudinal beam is inserted into the connecting sleeve.

[0009] Specifically, the connecting sleeve can protect the upper end of the longitudinal beam, and the cooperation between the connecting sleeve and the cross beam can play a "cross" fixing role, making the connection between the column-type elastic lead-viscous damper and the longitudinal beam and the cross beam more stable.

[0010] Furthermore, the upper end of the connecting sleeve is provided with an extension portion which is respectively in contact with the two long sides of the beam, and the upper ends of the two extension portions extend out of the top of the beam. A number of limit rods are connected between the upper ends of the two extension portions, and each of the limit rods is in contact with the top surface of the beam.

[0011] Specifically, by utilizing the connection relationship between the extension part and the limit rod, the connecting sleeve can be installed on the beam without welding or bolt locking, which facilitates the installation and use of the connecting sleeve and can achieve a weld-free connection between the connecting sleeve and the beam.

[0012] Furthermore, a plurality of reinforcing ribs are provided on both pairs of sides of the connecting sleeve, and the upper ends of the reinforcing ribs on the same side of the connecting sleeve extend to the upper side of the extension portion.

[0013] Specifically, the use of the reinforcing ribs can increase the bending strength of the extension portion, making it less likely for the extension portion to bend due to stress.

[0014] Furthermore, the cross section of the limiting rod is arranged in a circular shape, and both ends of the limiting rod are rotatably connected to the two extension parts respectively, and the length direction of each limiting rod is perpendicular to the length direction of the beam.

[0015] Specifically, the limiting rod with a circular cross-section is easy to roll, which makes it easy for workers to adjust the position of the connecting sleeve after installing the connecting sleeve.

[0016] Furthermore, a fixing plate is provided at the upper end of the connecting sleeve, the bottom surface of the fixing plate is connected to the upper sides of the two extensions, and the two ends of the fixing plate extend out of the opposite side surfaces of the two extensions respectively, and the two connecting seats are fixedly connected to the bottom surfaces of the two ends of the fixing plate respectively.

[0017] Specifically, the fixing plate can be used to fix the upper sides of the two extensions together, thereby improving the strength of the extensions. The connecting seat can be connected to the fixing plate and the extensions at the same time, thereby increasing the stability of the connecting seat.

[0018] Furthermore, it also includes two fan-shaped elastic lead-viscous dampers, the lower ends of the two fan-shaped elastic lead-viscous dampers are fixedly connected to the two pairs of sides of the longitudinal beam, and the upper ends of the two fan-shaped elastic lead-viscous dampers are fixedly connected to the bottom surface of the crossbeam.

[0019] Specifically, the use of fan-shaped elastic lead-viscous dampers can further achieve the effect of buffering and shock absorption, and the fan-shaped elastic lead-viscous dampers can complement the columnar elastic lead-viscous dampers, so that the four sides of the longitudinal beam can be stably connected to the cross beam.

[0020] Furthermore, the longitudinal beam includes an inner tube, an outer tube and several connecting plates. The outer tube is sleeved on the outside of the inner tube. Each connecting plate is equidistantly vertically arranged around the vertical center line of the inner tube. The two vertical sides of each connecting plate are fixedly connected to the inner tube and the outer tube respectively.

[0021] Specifically, the inner tube and the outer tube can be fixedly connected by each connecting plate, so that the longitudinal beam composed of the inner tube, the outer tube and the connecting plates has better strength and stability and can have greater compression and bending resistance.

[0022] Furthermore, the length of the inner tube is shorter than that of the outer tube, and the high-strength elastic buffer includes a first part and a second part. The lower end surface of the first part is fitted with the top of the inner tube, and the first part is fitted with a side surface of each connecting plate close to the inner tube. The second part is arranged above the first part, and the bottom surface of the second part is also connected to the upper side of each connecting plate.

[0023] Specifically, by embedding the high-strength elastic buffer in the first part of the inner tube and the second part extending out of the outer tube respectively, a fixed connection between the high-strength elastic buffer pad and the longitudinal beam can be achieved, thereby preventing the high-strength elastic buffer pad from being affected by vibration and causing position displacement.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. It can realize the shock-absorbing and anti-seismic connection between the longitudinal beam and the cross beam under the premise of ensuring the stable connection between the longitudinal beam and the cross beam, and ensure the connection strength between the longitudinal beam and the cross beam;

[0026] 2. It has multi-directional shock absorption and earthquake resistance performance, and can achieve a weld-free connection between the longitudinal beam and the cross beam, making the connection between the two more stable and firm. BRIEF DESCRIPTION OF THE DRAWINGS
