Description

Technical Field

[0001] The utility model belongs to the technical field of seismic isolation building engineering, and specifically relates to a vertical seismic isolation joint structure, which is mainly used in the vertical seismic isolation joint position of the seismic isolation building wall. Background Art

[0002] Seismic isolation buildings have the characteristic of relative movement between the upper and lower structures during earthquakes, so seismic isolation joints need to be set in seismic isolation buildings, mainly including horizontal seismic isolation joints and vertical seismic isolation joints. Different from conventional seismic isolation joint structures, vertical seismic isolation joint structures need to meet the requirements of large deformation during earthquakes in addition to meeting the wall functional requirements such as fire prevention, sound insulation, strength and stiffness. The vertical seismic isolation joint structure is one of the key points and difficulties of seismic isolation buildings. At present, some seismic isolation buildings do not properly handle the vertical seismic isolation joints, which leads to the obstruction of the seismic isolation movement of the building, thus affecting the seismic isolation effect of the seismic isolation building.

[0003] The traditional vertical seismic isolation joint structure has the following problems: 1) The joint design is unreasonable and the firmness is insufficient; 2) It is unable to cope with the large deformation requirements of the wall caused by earthquakes, resulting in the inability to fully exert the function of the seismic isolation joint structure; 3) The seismic isolation joint structure is not effective in fire prevention and sound insulation.

[0004] Utility Model

[0005] In view of this, the utility model provides a vertical seismic isolation joint structure, which is mainly arranged in the filling walls connected between seismic isolation buildings, between seismic isolation buildings and non-seismic isolation buildings, and at the junction of horizontal seismic isolation joints of different elevations of connected filling walls and seismic isolation layer walls. It can better meet the seismic isolation requirements of the vertical seismic isolation joint structure in seismic isolation buildings during earthquakes and non-earthquakes.

[0009] A fireproof and soundproof layer is provided in the area surrounded by the two steel pipe columns and the two cover plate layers;

[0010] The cover plate layer is overlapped and connected with the steel pipe column at the corresponding position;

[0011] The cover plate layer has two plates that can slide relatively in the horizontal direction along the seismic isolation wall joint to adapt to the change of the width of the vertical seismic isolation joint structure.

[0012] Furthermore, the cover plate layer is composed of two plates with right-angled concave and convex surfaces that are overlapped and staggered;

[0013] The two plates are respectively a first plate and a second plate;

[0014] The concave surface of the first plate and the convex surface of the second plate overlap to form a bite portion capable of relatively horizontal sliding.

[0015] Furthermore, it also includes an inorganic rolling curtain cloth layer, and the outer surface of the fireproof and sound-insulating layer is wrapped with the inorganic rolling curtain cloth layer.

[0016] Furthermore, both ends of the inorganic roller cord fabric layer are extended to the steel pipe columns on both sides and are connected to the steel pipe columns by fasteners.

[0017] Furthermore, the fireproof and sound-insulating layer is filled with fireproof rock wool.

[0018] Furthermore, the first plate and the second plate are made of aluminum alloy.

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0027] like Figure 1 As described above, this embodiment provides a vertical seismic isolation joint structure, which includes a steel pipe column 2, a cover layer 3, an inorganic rolling curtain fabric layer 4 and a fireproof and sound-insulating layer 5.

[0028] The vertical seismic isolation joint structure specifically refers to the gap existing between two seismic isolation walls 1, and is used to solve the large deformation of the vertical seismic isolation joint structure in the seismic isolation building and realize the function of the partition wall.

[0029] (i) Two steel pipe columns 2 are placed on both sides of the vertical isolation joint of the isolation wall, connected to the isolation wall 1 on the corresponding side, and used to support the isolation wall 1 and the vertical isolation joint structure. The steel pipe column 2 is a rectangular steel column, and its top or bottom is connected to the main structure connected to the corresponding isolation wall 1; the two steel pipe columns 2 are used to support the isolation wall 1 and the vertical isolation joint structure on both sides of the isolation wall joint. In addition, the front and rear sides of the steel pipe column 2 are connected to the fixed cover layer 3 and the roller curtain layer 4 through fasteners 8.

[0030] (ii) A cover layer 3 is provided between the two steel pipe columns 2, on both sides (i.e., on both sides in the thickness direction of the seismic isolation wall 1); the inner surface of the cover layer 3 is connected to the outer side surface of the steel pipe column 2 at the corresponding position by fasteners 8.

[0031] The cover layer 3 has two plates that can slide relative to each other in the horizontal direction of the seismic isolation wall 1 to accommodate large deformations between the seismic isolation walls. Figure 2 As shown, each cover layer 3 is composed of two plates with right-angled concave and convex surfaces that are staggered and overlapped; the two plates are respectively a first plate 6 and a second plate 7; wherein, the concave surface of the first plate 6 overlaps with the convex surface of the second plate 7 to form a bite portion that can slide relatively horizontally. The bite portion can slide relatively horizontally, and the maximum sliding length is the maximum displacement of the seismic isolation building. When the joint width between the two seismic isolation walls 1 increases, the bite portion becomes narrower (the sliding range is reduced), thereby achieving relative movement between the seismic isolation walls.

[0032] Furthermore, the first plate 6 and the second plate 7 are made of aluminum alloy.

[0033] (III) In a vertical seismic isolation joint structure, a fireproof and soundproof layer 5 is arranged in the area surrounded by two steel pipe columns 2 and two cover layers 3, and the left and right sides of the fireproof and soundproof layer 5 are connected to the two steel pipe columns 2; the thickness and density of the fireproof and soundproof layer 5 need to be selected according to different fire prevention and sound insulation requirements. An inorganic rolling curtain layer 4 is wrapped on the outside of the fireproof and soundproof layer 5; as an example, the rolling curtain layer 4 uses a special-grade inorganic fireproof rolling curtain, and the special-grade inorganic fireproof rolling curtain should have sufficient excess length to meet the requirements of large deformation of seismic isolation buildings.

[0034] Furthermore, both ends of the inorganic roller curtain fabric layer 4 and the cover plate layer 3 of the joint are extended to the steel pipe columns 2 on both sides and are fixedly connected to the steel pipe columns 2 by fasteners 8.

[0035] (IV) Screws are used for the fasteners 8; the fasteners 8 fix the inorganic roll-up fabric layer 4 and the cover layer 3 to the steel pipe column 2. The screws fix the inorganic roll-up fabric layer 4 to the outer surface of the steel pipe column 2; the first plate 6 and the second plate 7 in the cover layer 3 are respectively fixed to the steel pipe column 2 by screws.

[0036] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
