Description

Technical Field

[0001] The present disclosure belongs to the field of construction, and in particular relates to an anti-seismic and anti-shear mechanism and a building node connection device. Background Art

[0002] In a steel truss structure building, one end of the truss structure is connected to the main body of the building, and the other end of the truss structure is fixedly connected to the ground or other load-bearing components, so that the truss can transfer force to the ground or other load-bearing components, so that the main body of the building can be in a stable state.

[0003] Steel truss structures are more complex than traditional reinforced concrete structures, and steel has greater elastic deformation, which makes the force transmission method of each load-bearing component of the steel truss structure more complex than that of the reinforced concrete structure. As the main load-bearing component, the truss not only bears pressure, but also is subject to considerable shear force. Especially when an earthquake occurs or there is a large external load, the force borne by the truss will increase rapidly, making the truss structure prone to damage.

[0004] Existing technologies such as patent CN215253516U disclose a self-resetting steel tube concrete column-steel beam node, which includes a steel tube concrete column, a ribbed I-beam, prestressed tendons, curved angle steels, bolts, anchor plates, and stiffening ribs; a reserved channel is provided in the steel tube concrete column, and prestressed tendons are passed through the reserved channel and the stiffening rib channel, one end of the prestressed tendons is fixedly connected to the steel tube concrete column, and prestressing is applied, and the curved angle steels are respectively provided on the upper and lower sides of the ribbed I-beam, and the steel tube concrete column and the ribbed I-beam are connected by bolts, so that the prestressed tendons can restore the structure to its initial state after an earthquake, and the stiffening ribs can improve the shear resistance of the structure. At the same time, the curved angle steel has good energy dissipation capacity, so that the overall structure not only has good stress-bearing capacity, but also can reduce the residual deformation of the structure after an earthquake, and thus the self-resetting steel tube concrete column-steel beam node has excellent seismic resistance.

[0005] However, since the above-mentioned self-resetting steel tube concrete column-steel beam node only improves the structural bearing capacity and energy consumption capacity by arranging arc angle steels on both sides of the I-beam to transmit shear force and provide rotational stiffness, the shear resistance of the node is relatively weak. When the building body is exposed to a large earthquake intensity or is subjected to a large external load, the arc angle steel will be damaged due to the large shear force, thereby greatly reducing the shear resistance of the node and greatly reducing the safety of the building body. At the same time, when the building body is exposed to a large earthquake intensity or is subjected to a large external load, the pressure on the I-beam will also increase rapidly. The I-beam is fixedly connected to the steel tube concrete column so that the I-beam directly transmits the pressure to the steel tube concrete column. When the pressure is too large, the connection between the I-beam and the steel tube concrete column will be damaged due to mutual squeezing, which will lead to the destruction of the node, greatly reducing the seismic resistance of the node and further reducing the safety of the building body. Utility Model Content

[0018] In one embodiment, the height of the steel shear plate is at least 1 m.

[0019] In one embodiment, the adjacent ends of the steel stiffening ribs are respectively connected to the truss steel pipe and the steel support platform by butt welds.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this disclosure pertains. The terms used herein in the specification of this disclosure are intended only to describe specific embodiments and are not intended to limit this disclosure. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0035] like Figures 1 to 2 As shown, the seismic and shear-resistant mechanism 10 in one embodiment includes a truss steel pipe 100, a seismic buffer assembly 200 and a shear assembly 300. The truss steel pipe 100 is provided with a shear through hole 110 along the first direction X. The truss steel pipe 100 and the anchor body 20 are respectively fixedly connected to the two ends of the seismic buffer assembly 200. The seismic buffer assembly 200 is used to buffer the interaction force between the anchor body 20 and the truss steel pipe 100, so that when an earthquake occurs or under the action of external loads, the pressure on the truss steel pipe 100 increases rapidly, so that the anchor body 20 and the truss steel pipe 100 are squeezed against each other, and the seismic buffer assembly 200 can effectively buffer the interaction force between the anchor body 20 and the truss steel pipe 100, avoiding the direct mutual application of force between the anchor body 20 and the truss steel pipe 100, which makes the impact force between the anchor body 20 and the truss steel pipe 100 too large and causes the node to be damaged, thereby improving the seismic resistance of the seismic and shear-resistant mechanism 10 and greatly improving the safety of the building.

[0036] like Figures 1 to 2 As shown, further, the shear component 300 includes a steel stiffening rib 310 and a steel shear plate 320, the steel stiffening rib 310 is arranged on the outer wall of the truss steel pipe 100 along the second direction Y, the steel stiffening rib 310 is welded to the truss steel pipe 100 and the seismic buffer component 200, respectively, the steel shear plate 320 is passed through the shear through hole 110 along the first direction X, the steel shear plate 320 is welded to the truss steel pipe 100 and the seismic buffer component 200, respectively, and there is an angle between the first direction X and the second direction Y, so that when an earthquake occurs or under the action of external loads, the shear force on the truss steel pipe 100 increases rapidly, and the steel stiffening rib 310 and the steel shear plate 320 can simultaneously resist the shear force transmitted by the truss steel pipe 100 in two directions, so that the shear capacity of the seismic shear mechanism 10 is improved, thereby further improving the safety of the building.

[0037] In this embodiment, when an earthquake occurs or under the action of external loads, the force transmitted from the building body to the seismic and shear resistant mechanism 10 will increase rapidly. When the pressure on the seismic and shear resistant mechanism 10 increases rapidly, the interaction force between the anchor body 20 and the truss steel pipe 100 will also increase rapidly. The seismic buffer assembly 200 is arranged between the anchor assembly and the truss steel pipe 100 to create a buffer zone between the anchor body 20 and the truss steel pipe 100, thereby effectively buffering the interaction force between the anchor body 20 and the truss steel pipe 100, thereby greatly weakening the impact force between the anchor body 20 and the truss steel pipe 100.

[0038] When the shear force applied to the seismic and shear resistant mechanism 10 increases rapidly, the truss steel pipe 100 transmits the shear force to the steel stiffening ribs 310 and the steel shear plates 320. The steel stiffening ribs 310 and the steel shear plates 320 are arranged in different directions at one end of the seismic buffer assembly 200 and the truss steel pipe 100, so that the steel stiffening ribs 310 and the steel shear plates 320 can jointly resist the shear force transmitted by the truss steel pipe 100 in two directions.

[0039] The above-mentioned seismic and shear-resistant mechanism 10, since the truss steel pipe 100 is provided with a shear through hole 110 along the first direction X, the truss steel pipe 100 and the anchor body 20 are respectively fixedly connected to the two ends of the seismic buffer component 200, and the seismic buffer component 200 is used to buffer the interaction force between the anchor body 20 and the truss steel pipe 100, so that when an earthquake occurs or under the action of external loads, the pressure on the truss steel pipe 100 increases rapidly, so that the anchor body 20 and the truss steel pipe 100 are squeezed against each other, and the seismic buffer component 200 can effectively buffer the interaction force between the anchor body 20 and the truss steel pipe 100, avoiding the direct mutual application of force between the anchor body 20 and the truss steel pipe 100, which makes the impact force between the anchor body 20 and the truss steel pipe 100 too large and causes the node to be damaged, thereby improving the seismic ability of the seismic and shear-resistant mechanism 10 and greatly improving the safety of the building.

[0040] Since the shear assembly 300 includes steel stiffening ribs 310 and steel shear plates 320, the steel stiffening ribs 310 are arranged on the outer peripheral side of the truss steel pipe 100 along the second direction Y, and the steel stiffening ribs 310 are welded to the truss steel pipe 100 and the seismic buffer assembly 200 respectively, and the steel shear plates 320 are passed through the shear through holes 110 along the first direction X, and the steel shear plates 320 are welded to the truss steel pipe 100 and the seismic buffer assembly 200 respectively. There is an angle between the first direction X and the second direction Y, so that when an earthquake occurs or under the action of external loads, the shear force on the truss steel pipe 100 increases rapidly, and the steel stiffening ribs 310 and the steel shear plates 320 can simultaneously resist the shear force transmitted by the truss steel pipe 100 in two directions, so that the shear capacity of the seismic shear mechanism 10 is improved, thereby further improving the safety of the building.

[0041] like Figures 4 and 5 As shown in one embodiment, the seismic buffer assembly 200 includes a steel support platform 210, a plastic cushion layer 220 and a steel support 230. The upper end surface of the steel support platform 210 is welded to the steel stiffening rib 310, the steel shear plate 320 and the truss steel pipe 100, so that when the truss steel pipe 100 transmits the shear force to the steel stiffening rib 310 and the steel shear plate 320, the steel stiffening rib 310 and the steel shear plate 320 can be fixed on the steel support platform 210, so that the steel stiffening rib 310 and the steel shear plate 320 can be welded to the steel support platform 210. The shear plate 320 can jointly resist the shear force transmitted by the truss steel pipe 100; the lower end face of the steel support platform 210 is fixedly connected to the plastic cushion layer 220, the plastic cushion layer 220 is fixedly connected to the upper end face of the steel support 230, and the lower end face of the steel support 230 is fixedly connected to the anchor body 20, so that the interaction force between the truss steel pipe 100 and the anchor body 20 can be effectively buffered by the plastic cushion layer 220, thereby enabling the seismic buffer assembly 200 to reduce the impact force between the truss steel pipe 100 and the anchor body 20.

[0042] like Figures 4 and 5 As shown, in one embodiment, the seismic buffer assembly 200 also includes an elastic telescopic member 240, which is arranged on the lower end surface of the steel support platform 210 along the outer edge of the steel support 230, so that the interaction force between the truss steel pipe 100 and the anchor body 20 can be further buffered by the elastic telescopic member 240, thereby further weakening the impact force between the truss steel pipe 100 and the anchor body 20.

[0043] like Figure 6 As shown, in one embodiment, the angle is 90° to improve the shear resistance of the shear resistant component 300 .

[0044] like Figure 2 As shown, in one embodiment, the number of the steel stiffening ribs 310 is two, and the two steel stiffening ribs 310 are relatively spaced apart along the second direction Y on both sides of the truss steel pipe 100 so that the steel stiffening ribs 310 can better resist the shear force transmitted by the truss steel pipe 100.

[0045] like Figures 1 to 3 As shown, in one embodiment, there are two shear through holes 110, and the two shear through holes 110 are arranged opposite to each other along the first direction X, so that the steel shear plate 320 passes through the truss steel pipe 100, so that the steel shear plate 320 can better resist the shear force transmitted by the truss steel pipe 100.

[0046] like Figure 1 As shown, in one embodiment, the height of the steel shear plate 320 is at least 1 m, so that the shear resistance of the steel shear plate 320 is further improved.

[0047] like Figure 2 As shown, in one embodiment, the adjacent two ends of the steel stiffening rib 310 are connected to the truss steel pipe 100 and the steel support platform 210 respectively by butt welds to improve the connection strength of the steel stiffening rib 310 with the truss steel pipe 100 and the steel support platform 210, thereby further improving the shear resistance of the steel stiffening rib 310.

[0048] like Figure 2 As shown, in one embodiment, the steel shear plate 320 is connected to the truss steel pipe 100 and the steel support platform 210 respectively by butt welds to improve the connection strength of the steel shear plate 320 and the truss steel pipe 100 and the steel support platform 210 respectively, and further improve the shear resistance of the steel shear plate 320.

[0049] The present disclosure further provides a building node connection device, comprising the seismic and shear resistant mechanism 10 described in any one of the above embodiments.

[0050] Compared with the prior art, the present disclosure has at least the following advantages:

[0052] 2. Since the shear assembly 300 includes steel stiffening ribs 310 and steel shear plates 320, the steel stiffening ribs 310 are arranged on the outer peripheral side of the truss steel pipe 100 along the second direction Y, and the steel stiffening ribs 310 are welded to the truss steel pipe 100 and the seismic buffer assembly 200 respectively, and the steel shear plates 320 are passed through the shear through holes 110 along the first direction X, and the steel shear plates 320 are welded to the truss steel pipe 100 and the seismic buffer assembly 200 respectively. There is an angle between the first direction X and the second direction Y, so that when an earthquake occurs or under the action of external loads, the shear force on the truss steel pipe 100 increases rapidly, and the steel stiffening ribs 310 and the steel shear plates 320 can simultaneously resist the shear force transmitted by the truss steel pipe 100 in two directions, so that the shear capacity of the seismic shear mechanism 10 is improved, thereby further improving the safety of the building.
