Description

Technical Field

[0001] The invention relates to the technical field of seismic isolation buildings, and in particular to a slide rail type isolation joint device and a seismic isolation building. Background Art

[0002] For buildings with complex appearance and built in high-intensity areas, it is often necessary to divide the building into several relatively regular structural units during design. The structural periods of each structural unit are often quite different. If seismic isolation technology is used at the same time, there will be a large relative displacement between two adjacent structural units when an earthquake occurs. In order to prevent the structural units from interfering with each other during vibration and affecting the seismic isolation effect, a wide isolation gap needs to be set between each structural unit. As a building functional whole, each structural unit often needs a certain degree of connection.

[0003] In the commonly used isolation joint connection technology, the isolation joint cover plate is placed directly in an L-shaped U-shaped groove with two ends open, and the vertical constraint is only the building surface layer on the other side. When an earthquake occurs, the isolation joint cover plate is easy to be separated from the U-shaped groove. Summary of the invention

[0026] The embodiment of the present invention provides a slide rail type isolation gap device, such as Figure 1-Figure 3 As shown, it includes a horizontal sliding groove 1, an isolation seam cover plate 2, a vertical sliding groove 3, and a sliding device 4.

[0027] The horizontal sliding groove 1 is a U-shaped groove, and includes a first surface and a second surface adjacent to the opening of the horizontal sliding groove 1 , and a side surface opposite to the opening, and the first surface is opposite to the second surface.

[0028] The isolation seam cover plate 2 extends from the opening into the horizontal sliding groove 1, and there is a distance between it and the side surface; the lower surface of the isolation seam cover plate 2 is fixed on the sliding device 4, and the sliding device 4 is used to make the isolation seam cover plate 2 move along the first direction in the vertical sliding groove 3, and the first direction is the distance direction between the first surface and the second surface.

[0029] Here, the slide rail type isolation joint device can be applied to a seismic isolation building, which includes a plurality of building units arranged at intervals, and the slide rail type isolation joint device is fixed to adjacent building units. On this basis, there is an isolation joint between adjacent building units, and the slide rail type isolation joint device is at least partially located in the isolation joint.

[0030] In some embodiments, Figure 2 As shown, the first surface and the second surface are two opposite surfaces perpendicular to the paper surface.

[0031] The isolation gap cover plate 2 can move along the first direction, but the first surface and the second surface can limit the movement of the isolation gap cover plate 2 along the first direction. The spacing between the isolation gap cover plate 2 and the first surface and the second surface can be 10-20 mm.

[0032] In some embodiments, the horizontal sliding groove 1 further includes a third surface and a fourth surface opposite to each other, and the third surface and the fourth surface are both adjacent to the first surface and the second surface. Figure 2 As shown, the third surface and the fourth surface are the upper and lower surfaces.

[0033] The isolation gap cover plate 2 can be completely attached to the third surface and the fourth surface, and the isolation gap cover plate 2 cannot move along the second direction, wherein the second direction is the distance direction between the third surface and the fourth surface.

[0034] In some embodiments, the isolation gap cover plate 2 extends into the horizontal sliding groove 1 and can move along the second direction, but the side of the horizontal sliding groove 1 can limit the isolation gap cover plate 2 along the second direction.

[0035] There is a distance between the side of the horizontal sliding groove 1 and the isolation gap cover plate 2. When an earthquake occurs, the isolation gap cover plate 2 can move along the third direction in the horizontal sliding groove 1. The third direction is the distance direction between the opening of the horizontal sliding groove 1 and the side.

[0036] In some embodiments, the fixing method of the isolation gap cover plate 2 and the sliding device 4 is not limited.

[0037] For example, after the sliding device 4 is manufactured, the sliding device can be fixed to the lower surface of the isolation joint cover plate 2 by anchor bolts. On this basis, the sliding device 4 is also fixed to the vertical sliding device.

[0038] In some embodiments, the thickness of the horizontal sliding groove 1 may be 10-20 mm.

[0039] In some embodiments, the length of the isolation joint cover plate 2 inserted into the horizontal sliding groove can be the net width of the isolation joint to prevent the isolation joint cover plate 2 from falling off from the horizontal sliding groove 1 during an earthquake.

[0040] The embodiment of the present invention provides a sliding rail type isolation joint device, comprising a horizontal sliding groove 1, an isolation joint cover plate 2, a vertical sliding groove 3, and a sliding device 4. When the sliding rail type isolation joint device is applied between buildings, on the one hand, the isolation joint cover plate 2 extends into the horizontal sliding groove 1 and has a spacing with the side of the horizontal sliding groove 1, so that when an earthquake occurs, the movement in the third direction is always in the horizontal sliding groove 1, with a certain movement space, and will not cause the building surface to bulge or dent; on the other hand, the isolation joint cover plate 2 can move along the first direction on the vertical sliding groove 3 with the sliding device 4, and the movement in the first direction is also always in the horizontal sliding groove, so that when an earthquake occurs, the movement in the first direction is always in the horizontal sliding groove 1 and on the vertical sliding groove 3, so it will not cause the building surface to bulge or dent.

[0041] Optionally, the isolation seam cover plate 2 is movably fixed on the vertical sliding groove 3 through an anti-fall structure 6 .

[0042] That is, the isolation gap cover plate 2 is fixed on the vertical sliding groove 3 through the anti-fall structure 6, and the isolation gap cover plate 2 can also move within a certain distance range.

[0043] In some embodiments, the number of the anti-fall structure 6 can be one or more.

[0044] For example, the number of the anti-fall structures 6 may be two, and the two anti-fall structures 6 are respectively disposed at two ends of the sliding device 4 .

[0045] In some embodiments, the specific structure of the anti-fall structure 6 is not limited.

[0046] For example, the anti-fall structure 6 may be an iron chain or the like.

[0047] In some embodiments, one end of the iron chain is fixed on the isolation gap cover plate 2 and the other end is fixed on the vertical sliding groove 3, and the movable length of the iron chain is greater than or equal to the width of the isolation gap, which is used to limit the maximum movement distance of the isolation gap cover plate 2 along the first direction to prevent the isolation gap cover plate 2 from detaching from the vertical sliding groove 3.

[0048] In some embodiments, the iron chain can be fixed to the isolation seam cover plate 2 and the vertical sliding groove 3 respectively by means of embedded parts or welding.

[0049] In the embodiment of the present invention, the isolation seam cover plate 2 is fixed to the vertical sliding groove 3 by the anti-fall structure 6, which can prevent the isolation seam cover plate 2 from falling and becoming ineffective on the one hand; on the other hand, it can also ensure that the isolation seam cover plate 2 moves within a certain distance range.

[0050] Optionally, the vertical sliding groove 3 includes a first sub-sliding groove and a second sub-sliding groove, and both the first sub-sliding groove and the second sub-sliding groove are L-shaped.

[0051] The first sliding groove includes a long surface and a short surface which are perpendicular to each other, the long surface is used to carry the sliding device 4, and the short surface is used as a retaining wall. The second sub-sliding groove is fixedly connected to the long surface.

[0052] In some embodiments, the material and thickness of the first sub-sliding groove and the second sub-sliding groove are not limited, as long as the first sub-sliding groove and the second sub-sliding groove are sufficient to be fixed on the building unit and can carry the sliding device 4.

[0053] For example, the material of the first sub-sliding groove and the second sub-sliding groove can be galvanized steel plate with a thickness of 10-20 mm.

[0054] In some embodiments, the second sub-sliding groove is fixed to the building unit by embedded parts, and the first sub-sliding groove is fixed to the second sub-sliding groove by welding.

[0055] In the embodiment of the present invention, the first sub-sliding groove can carry the sliding device 4 and prevent the sliding device 4 from falling off, and the second sub-sliding groove can be used to fix the vertical sliding device 3 as a whole on the building unit.

[0056] Optional, such as Figure 4 As shown, the sliding device 4 includes a slide rail 9, a tetrafluoroethylene filler 10, and a slide rail support 11. The upper surface of the slide rail 9 is fixedly connected to the isolation seam cover plate 2; the tetrafluoroethylene filler 10 is fixed in the slide rail support 11, and the upper surface of the slide rail support 11 has a groove, and the slide rail 9 is located in the groove; the groove is used to fix the slide rail 9 along the second direction and the third direction.

[0057] In some embodiments, the groove is used to fix the slide rail 9 along the second direction and the third direction, that is, the slide rail 9 located in the groove cannot move along the second direction and the third direction, and thus the isolation seam cover plate 2 fixedly connected to the slide rail 9 cannot move along the second direction and the third direction in the vertical sliding groove 3.

[0058] In some embodiments, the height of the vertical sliding slot 3 should be adapted to the size of the sliding rail 9 so that the height of the building unit does not need to be adjusted to accommodate the configuration of the insulation joint.

[0059] In the embodiment of the present invention, the sliding device 4 includes a slide rail 9, a tetrafluoroethylene filler 10, and a slide rail support 11. The tetrafluoroethylene filler 10 can be used to limit the movement direction of the slide rail 9, thereby limiting the movement of the isolation seam cover 2 in the vertical sliding groove 3.

[0060] An embodiment of the present invention further provides a seismic isolation building, which includes a plurality of building units arranged at intervals and the slide rail type isolation joint device described in any of the above embodiments; the horizontal sliding groove 1 and the vertical sliding groove 3 are respectively fixed on adjacent building units.

[0061] In some embodiments, when the vertical sliding groove 3 includes a first sub-sliding groove and a second sub-sliding groove, the second sliding groove can be overlapped on one building unit by bolts; and the horizontal sliding groove 1 can be overlapped on another building unit by bolts.

[0062] Other explanations of the embodiment of the present invention are the same as those of the aforementioned slide rail type isolation gap device and will not be repeated here.

[0063] An embodiment of the present invention provides a seismic isolation building, including the slide rail type isolation joint device described in any of the above embodiments. On the one hand, the isolation joint cover plate 2 extends into the horizontal sliding groove 1 and has a spacing with the side of the horizontal sliding groove 1, so that when an earthquake occurs, the movement in the third direction is always in the horizontal sliding groove 1, with a certain movement space, and will not cause the building surface to bulge or dent; on the other hand, the isolation joint cover plate 2 can move along the first direction on the vertical sliding groove 3 with the sliding device 4, and the movement in the first direction is also always in the horizontal sliding groove. In this way, when an earthquake occurs, the movement in the first direction is always in the horizontal sliding groove 1 and on the vertical sliding groove 3, so it will not cause the building surface to bulge or dent.

[0064] Optional, such as Figure 3 As shown, the isolation joint is also provided with a flexible fireproof isolation belt 8 and a flexible waterstop belt 7 located above the flexible fireproof isolation belt 8.

[0065] Among them, the flexible fire isolation belt 8 and the flexible water stop belt 7 can be arranged between two adjacent building units, and both are located below the sliding rail type isolation joint device.

[0066] In some embodiments, in order to further ensure the safety of residents, the fire resistance limit of the flexible fire isolation belt 8 may be no less than 1.5 hours.

[0067] In the embodiment of the present invention, the safety of residents can be ensured by providing a flexible fire isolation belt 8 and a flexible water stop belt 7.

[0068] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto.
