Description

TECHNICAL FIELD

[0001] The present application belongs to the field of building engineering, and particularly relates to a structure of a cross-structural-joint passage with energy-dissipation and shock-reduction devices between attached buildings. BACKGROUND

[0002] Attached buildings refer to several building units built together, and there is generally only a structural joint of a certain width between two building units. The structural joint refers to a gap set between attached buildings to avoid collision under the action of horizontal forces such as earthquakes and wind loads.

[0003] In order to facilitate plane traffic, a building passage connecting the attached buildings, i.e., a cross-structural-joint passage, is arranged at the structural joint. In the prior art, the two ends of the cross-structural-joint passage are generally fixed to the attached buildings.

[0004] Under the action of horizontal forces such as earthquakes and wind loads, movement of the attached buildings along the width direction of the structural joint or horizontal plane displacement of the attached buildings changes the distance between the two fixed positions of the cross-structural-joint passage, causing damage to the cross-structural-joint passage. The width direction of the structural joint and the displacement direction are perpendicular to each other in the plane. SUMMARY

[0005] In view of the above problems of the prior art, the present application provides a structure of a cross-structural-joint passage with energy-dissipation and shock-reduction devices between attached buildings. The present application solves the problems of damage to the cross-structural-joint passage caused by movement of the attached buildings along the width direction of the structural joint and damage to the cross-structural-joint passage caused by horizontal plane displacement of the attached buildings. The present application has the functions of ensuring the safety of the passage, energy dissipation and shock reduction, and collision prevention of the attached buildings.

[0006] The technical scheme of the present application is as follows: a structure of a cross-structural-joint passage with energy-dissipation and shock-reduction devices between attached buildings, a first building and a second building are attached, a structural joint is located between the first building and the second building, one end of a cross-joint member is fixed to a floor of the first building, the other end of the cross-joint member extends to a floor of the second building after crossing the structural joint and can slide along the floor of the second building; an energy-dissipation and shock-reduction device is located below the cross-joint member and in the structural joint, the energy-dissipation and shock-reduction device comprises a shear-type damper and a support member; the shear-type damper is fixed to the bottom of the cross-joint member; the shear-type damper is fixed to the second building through the support member; the horizontal distance between the energy-dissipation and shock-reduction device and the first building is greater than the maximum horizontal shear deformation of the shear-type damper in the maximum sliding direction; the overlap length of the cross-joint member on the floor of the second building is greater than the maximum horizontal shear deformation of the shear-type damper in the maximum sliding direction.

[0007] Based on the above technical features: the cross-seam member is provided with a wall body at the side of the second building floor, a dislocation groove is arranged at the contact position of the wall body and the cross-seam member, and the cross-seam member moves in the dislocation groove when the first building and the second building dislocate, and the dislocation direction and the sliding direction are perpendicular to each other in the horizontal plane.

[0008] Based on the above technical features: the shear type damper is multiple and is arranged along the width direction of the cross-structure seam passage.

[0009] Based on the above technical features: the support member is fixed outside the outer boundary structure member of the second building, and the lower end of the shear type damper is fixed on the support member.

[0010] In the above scheme, the floor should be understood in a broad sense, and also includes the roof. The cross-seam member can be a metal member or a concrete member, etc. The fixing mode of the cross-seam member and the floor of the first building can adopt any existing technology. The shear type damper can be a rubber damper or a mild steel damper, etc. The shear type damper itself belongs to the existing technology. The wall body can also be understood in a broad sense, including a fence plate or a handrail, etc.

[0011] The working principle of the structure is as follows: the cross-seam member is a component of the cross-structure seam passage of the attached building, one end is fixed on the floor of the first building as a fixed end, the other end is overlapped with the floor of the second building to form a sliding end, the cross-seam member can slide on the floor of the second building under the action of horizontal forces such as earthquake and wind load, the cross-seam member is connected with the shear type damper, and the shear type damper is a device that generates damping and dissipates energy through shear deformation. When the attached building dislocates in the plane under the action of horizontal forces such as earthquake and wind load, the cross-seam member moves in the dislocation groove at the root of the wall body of the second building, so as to avoid the collision and damage of the cross-seam member and the wall body.

[0012] The beneficial effects of the present application are as follows:

[0013] 1. Ensure the structural safety and building function of the cross-structure seam passage: under the action of horizontal forces, the cross-structure seam passage between the attached buildings can freely slide in two directions of the floor of the second building, so as to avoid the damage of the passage and ensure the smoothness of the building passage.

[0014] 2. Have the energy dissipation and vibration reduction effect: the shear type damper improves the damping of the building, and reduces the internal force of the attached building under the action of horizontal forces such as earthquake and wind load. BRIEF DESCRIPTION OF DRAWINGS

For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0026] Furthermore, in the description of the present application, the meaning of "a plurality of" is two or more, unless otherwise specified.

[0027] As shown in Figure 1 , the first building and the second building are adjoined, and a structural joint 10 is located between the first building and the second building. A structural joint passage 9 is provided between the first building floor 2 and the second building floor 3 to communicate the first building floor 2 and the second building floor 3 across the structural joint 10. The wall 11 on the second building floor 3 is arranged on both sides of the structural joint passage 9.

[0028] As shown in Figure 2 and Figure 3 , the structural joint is located between the first building and the second building. One end of the cross-joint member 1 is fixed to the first building floor 2, and the other end extends to the second building floor 3 across the structural joint, with an overlap length B. The cross-joint member 1 can slide on the second building floor 3 under the action of horizontal forces such as earthquake and wind load, i.e. slide in the x-axis direction as shown in Figure 1 . When the cross-joint member 1 is a metal member, the fixed connection between the cross-joint member 1 and the first building floor 2 can be as shown in Figure 2 , a pre-embedded part 8 is arranged on the first building floor 2, and one end of the cross-joint member 1 is fixed to the pre-embedded part 8; or as shown in Figure 3 , one end of the cross-joint member 1 is welded to the first building outer boundary metal member 4b of the first building floor 2.

[0029] The energy dissipation and seismic mitigation device is located in the structural joint. The energy dissipation and seismic mitigation device includes a shear type damper and a support member 7. The shear type damper includes a rubber damper 6a and a mild steel damper 6b, and the shear type damper can be fixed to the bottom of the cross-joint member 1. The shear type damper is fixed to the second building through the support member 7. The horizontal distance A between the energy dissipation and seismic mitigation device and the first building is greater than the maximum horizontal shear deformation in the sliding direction of the shear type damper. The overlap length B of the cross-joint member 1 on the second building floor 3 is greater than the maximum horizontal shear deformation in the sliding direction of the shear type damper.

[0030] As shown in Figure 4 and Figure 5 , the shear type damper is multiple and arranged at intervals along the width direction of the structural joint passage. The shear type damper can be a rubber damper 6a as shown in Figure 4 or a mild steel damper 6b as shown in Figure 5 . Figure 4 and Figure 5 The number of shear type dampers is only one example, and the shear type damper can be one or more.

[0031] The lower end of the shear type damper is fixedly connected to the support member 7, and the support member 7 is fixed to the second building outer boundary concrete member 5a (seeFigure 2 ) or the second building outer boundary metal member 5b (see Figure 3 ). As shown in Figure 2 , the support member 7 can be fixedly connected with the second building outer boundary concrete member 5b by using a pre-embedded member 8; or as shown in Figure 3 , the support member 7 can be directly welded on the second building outer boundary metal member 5b. The support member 7 can be a metal member or a concrete member.

[0032] The first building outer boundary member and the second building outer boundary structural member can be a wall, a concrete beam, a steel-concrete member or a metal member, etc. As shown in Figure 2 , the first building outer boundary member and the second building outer boundary structural member are respectively a first building outer boundary concrete member 4a and a second building outer boundary concrete member 5a; Figure 3 , the first building outer boundary member and the second building outer boundary structural member are respectively a first building outer boundary metal member 4b and a second building outer boundary metal member 5b.

[0033] The cross-seam member 1, the first building outer boundary member and the second building outer boundary structural member and the support member 7 have sufficient strength and rigidity to support the shear-type damper to undergo shear deformation.

[0034] As an optimization, as shown in Figure 1 and Figure 6 , the cross-seam member 1 is located at the side of the second building floor 3 and is provided with a wall 11, and a dislocation groove 12 is arranged at the contact position of the wall 11 and the cross-seam member 1, so that the cross-seam member 1 moves in the dislocation groove 12 when the first building and the second building dislocate. The dislocation direction and the sliding direction are perpendicular to each other in the horizontal plane, i.e. the dislocation direction is the y-axis direction shown in Figure 1 . The length C of the dislocation groove is greater than the horizontal dislocation distance of the attached building.

[0035] The advantage of arranging the dislocation groove 12 is that the wall 11 does not block the movement of the cross-seam member 1 in the y-axis direction of the second building floor.

[0036] The above is only the preferred embodiment of the present application, and it should be noted that for those skilled in the art, without departing from the technical principles of the present application, a number of improvements and replacements can be made, and these improvements and replacements should also be considered as the protection scope of the present application.
