Description

Technical Field

[0001] The utility model relates to the technical field of comprehensive reconstruction of existing buildings, in particular to a connecting device for installing an elevator in an existing building. Background Art

[0002] According to current engineering practice, due to site space limitations and to reduce the impact on the original building, most of the elevator shafts are separated from the existing building, and the vertical force is borne by the foundation of the elevator shaft. However, due to the small plane size, large aspect ratio and low lateral stiffness of the elevator shaft, each floor of the installed elevator shaft needs to be connected to the beams or columns of the existing building to limit its lateral displacement. Usually, the installed elevator shaft and the existing building are rigidly connected together by anchor bolts or embedded steel bars.

[0003] Although this type of connection plays a certain role in restraining the lateral displacement and slight settlement of the elevator shaft, since the existing building has been built and put into use for many years, the foundation settlement has tended to be stable. The installation of the elevator is a new building, and after completion it will inevitably experience varying degrees of settlement, causing the rigid connection to tear and causing varying degrees of damage to the existing building.

[0032] refer to Figure 1-5 The utility model provides an existing elevator connection device, including an end plate 1, a damper 2 and a slider 3. The end plate 1 is provided with a lug plate 4. The slider 3 is vertically slidably connected to a guide rail 6 on the elevator shaft. The slider 3 can slide up and down relative to the guide rail 6. One end of the damper 2 is firmly connected to the slider 3, and the other end of the damper 2 is laterally hinged to the lug plate 4. The end plate 1 and the slider 3 are made of rigid materials such as steel plates or iron plates; the damper 2 is generally a viscous damper, and the damper is selected according to the lateral stiffness ratio of the elevator shaft and the existing building, and the local estimated maximum typhoon intensity and earthquake size.

[0033] Specifically, the slider 3 includes a connecting cavity 31 and a card slot 32 . The connecting cavity 31 includes a main board 311 . The card slot 32 is disposed on one side of the main board 311 .

[0034] The present application realizes a sliding connection between the existing building and the added elevator shaft structure by installing an elevator connection device on the existing building. The end plate 1 is rigidly fixedly connected to the existing building, one end of the damper 2 is hinged to the ear plate 4, the ear plate 4 is fixedly connected to the end plate 1, and the other end of the damper 2 is tightly connected to the slider 3. The slider 3 can slide up and down relative to the guide rail 6. When the added elevator sinks, the guide rail 6 slides down relative to the slider 3, and the slider is relatively still up and down. The damper 2 is basically not subjected to downward pulling force, and the end plate 1 fixedly connected to the existing building is basically not subjected to downward pulling force, so that the existing building is not affected when the added elevator shaft structure sinks, and the existing building will not be damaged by the settlement of the added elevator shaft structure; the damper 2 has the function of energy dissipation and shock absorption. When an earthquake or strong wind occurs, it can significantly reduce the damage to the added elevator shaft and the existing building, and at the same time, it can provide constraints on the lateral displacement of the elevator shaft during normal use.

[0035] Specifically, the slot 32 is vertically through, and the ear plate 4 is arranged horizontally. In the present application, the direction in which the slider 3 slides relative to the guide rail is vertical, that is, the direction perpendicular to the ground after the connecting device is installed, and the direction perpendicular to the vertical is horizontal. Specifically, the ear plate 4 is a flat block, and the horizontal arrangement of the ear plate 4 means that the flat surface is arranged in the horizontal direction, so that the damper 2 rotates horizontally relative to the ear plate 4.

[0036] In this embodiment, the slider 3 includes a slot 32, and a guide rail is provided on the elevator shaft. It can be understood that in other embodiments, the slider 3 includes a guide rail 6, and a slot 32 is provided on the elevator shaft. The slot 32 is connected with the guide rail 6 to achieve up and down sliding.

[0037] Specifically, the card slot 32 includes two connecting plates 321 and two side plates 322 perpendicular to the connecting plates 321 . The two side plates 322 are parallel to each other and arranged perpendicular to the main board 311 . The connecting plates 321 , the side plates 322 and the main board 311 form the card slot 32 .

[0038] In this embodiment, the slot 32 has a notch 323, and the two connecting plates 321 are spaced apart to form the notch 323. The width of the notch 323 is smaller than the spacing width of the two side plates 322, so that the guide rail 6 and the slider 3 are engaged. When the elevator is installed and sinks or shakes, the slider is not easily separated from the guide rail and can provide lateral constraints on the elevator shaft structure.

[0039] refer to Figure 2 , Figure 3 and Figure 5The connection chamber 31 further includes a partition 316, a first cover plate 312 and a second cover plate 313. One end of the partition 316 is vertically connected to the other side of the main board 311. Specifically, the partition 316 is arranged along the center line of the card slot 32 in the vertical direction. The other end of the partition 316 is connected to the first cover plate 312 and the second cover plate 313. The first cover plate 312 is provided with a first mounting hole 314, and the second cover plate 313 is provided with a second mounting hole 315. The first mounting hole 314 and the second mounting hole 315 are symmetrically arranged relative to both sides of the partition 316. The main board 311, the partition 316, the first cover plate 312 and the second cover plate 313 are enclosed to form the connection chamber 31. The connection chamber 31 is provided, and one end of the damper 2 partially extends into the connection chamber 31, which has a convenient installation space.

[0040] Specifically, the damper 2 includes a first damper 21 and a second damper 22, the ear plate 4 includes a first ear plate 41 and a second ear plate 42, the first damper 21 includes a first bolt joint 211 at one end, a first double-ear joint 212 at the other end, the first bolt joint 211 is installed in the first mounting hole 314, the first double-ear joint 212 is installed in the first ear plate 41, the second damper includes a second bolt joint 221 at one end, a second double-ear joint 222 at the other end, the second bolt joint 221 is installed in the second mounting hole 315, and the second double-ear joint 222 is installed in the second ear plate 42. In the present application, the first damper 21 and the second damper 22 have the same model and specification and have a large initial stiffness, and can also provide lateral constraints on the lateral displacement of the elevator shaft in daily use.

[0041] Specifically, the connection between the first cover plate 312 and the second cover plate 313 is higher than the two sides, and is higher in the middle and lower on both sides relative to the main board 311, so that the first cover plate and the second cover plate are arranged in an inclined plane, and a certain angle is formed between the first cover plate 312 and the second cover plate 313. It can be understood that when there are two dampers 2 distributed on both sides of the partition to form a triangular arrangement with the existing building, the dampers are basically perpendicular to the first cover plate and the second cover plate, and the first bolt joint 211 and the second bolt joint 221 are better fitted on the first cover plate 312 and the second cover plate 313.

[0042] In this embodiment, the first double-ear joint 212 and the second double-ear joint 222 are respectively clamped on the upper and lower surfaces of the first ear plate 41 and the second ear plate 42, and the anchor bolts 7 pass through the first double-ear joint and the second double-ear joint and the second ear plate 42 respectively, so that the damper 2 and the ear plate 4 can be rotatably hinged, the first bolt joint 211 is first screwed into the nut 8, and then the first bolt joint 211 is passed through the first mounting hole 314, and finally another nut 8 is screwed into the top of the first bolt joint 211 and fixed on the first cover plate 312. The second damper 22 fixes the second bolt joint 221 on the second cover plate 313 in the same way, and is installed in a triangular shape with the existing building wall as the base and the connecting cavity 31 as the vertex. The triangle has stability, making the connecting device more stable and reliable.

[0043] refer to Figure 1 In this embodiment, the first ear plate 31 and the second ear plate 32 are transversely welded to the same end plate 1. In this way, the end plate has a larger area, and more fastening screws 9 can be installed on the end plate, thereby increasing the fastening degree between the end plate and the existing building.

[0044] In other embodiments, the first ear plate 31 and the second ear plate 32 can be installed on the two end plates 1 respectively, which can reduce consumables to a certain extent and make installation and disassembly more convenient.

[0045] The end plate 1 is fixedly connected to the existing building by a plurality of screws 5. In this embodiment, four screws 5 are used and distributed at four corner positions of the end plate 1. The first damper 21 and the second damper 22 are in the same horizontal plane as the first ear plate 31 and the second ear plate 32, and the slider 3 is buckled with the guide rail 6 of the elevator shaft. When an earthquake or strong wind occurs, the damper 2 has the function of energy dissipation and shock absorption, which can significantly reduce the damage to the elevator shaft and the existing building, and at the same time, it can provide constraints on the lateral displacement of the elevator shaft during normal use; when the elevator shaft is subsided, the guide rail 6 slides down relative to the slider 3, and the slider 3 is relatively still up and down, and the damper 2 is basically not subjected to downward tension, and the end plate 1 fixedly connected to the existing building is basically not subjected to downward tension, so that when the elevator shaft structure is subsided, the existing building is not affected, and the existing building will not be damaged by the subsidence of the elevator shaft structure.

[0046] The above are only preferred embodiments of the present invention, and do not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the present invention.
