Description

Technical Field

[0001] The invention relates to the technical field of elevator shafts, and in particular to a steel structure elevator shaft. Background Art

[0002] Installing an elevator outside a building is an important part of the renovation of an old building. It is done by strengthening the steel structure elevator shaft outside the building to ensure that the installed elevator can run smoothly. Although this renovation measure has brought great convenience to residents, there are still the following safety hazards:

[0003] 1. The steel structure elevator shaft is located outdoors and is directly subject to wind force. Since the shaft is directly connected to the old building through the steel structure, if the shaft shakes significantly, it will cause great safety hazards to the already fragile old building through force conduction. Although the impact is not obvious at the beginning of the installation of the elevator, as the old building further ages, the strength of the steel structure elevator will weaken over time, and this hidden danger will be further strengthened.

[0004] 2. Most of the existing steel elevator shafts are cubic structures, which have large wind resistance when subjected to wind force. In the long run, this will affect the structural stability of the shaft.

[0005] 3. Since the existing steel structure elevator shaft is set outdoors, it is inevitable that high temperatures will be generated in the shaft in summer. The lack of cooling measures will also reduce the comfort of riding the elevator. Utility Model Content

[0006] The present invention provides a steel structure elevator shaft, the purpose of which is to solve the problems described in the background technology section 1-3.

[0007] To achieve the above purpose, the technical solution of this novel invention is:

[0008] A steel structure elevator shaft comprises a cement seat, an elevator shaft, and a steel structure vibration damping cylinder. The elevator shaft is arranged in the steel structure vibration damping cylinder. The bottom ends of the elevator shaft and the steel structure vibration damping cylinder are both pre-buried in the cement seat. The cement seat is pre-buried in the soil outside the building structure. A plurality of vibration damping rods are evenly distributed between the outer wall of the elevator shaft and the inner wall of the steel structure vibration damping cylinder.

[0009] Preferably, the elevator shaft includes 4 vertical rods distributed in a rectangular shape and arranged longitudinally, a plurality of installation frames welded between adjacent vertical rods and stacked up and down, and tempered glass fixedly connected to the inner side of the installation frame, and the bottom ends of the vertical rods are pre-buried in a cement seat.

[0010] Preferably, a plurality of cross bars are evenly distributed between adjacent vertical bars and outside the tempered glass, both ends of the cross bars are welded to the corresponding vertical bars, and the cross bars on different sides of the elevator shaft are staggered.

[0011] Preferably, the inner wall of the steel structure vibration-damping cylinder is connected to the relative cross bars through a plurality of vibration-damping rods.

[0012] Preferably, the steel structure vibration damping cylinder comprises a cylindrical steel structure cage, a steel plate welded in the gap of the steel structure cage, the bottom end of the steel structure cage is embedded in a cement seat; a vibration damping rod is connected between the inner wall of the steel structure cage and the cross bar.

[0013] Preferably, the vibration damping rod is made of shape memory alloy, and both ends of the vibration damping rod are respectively welded to the cross bar and the inner wall of the steel structure cage.

[0014] Preferably, the vibration-damping rod is a viscoelastic damper, and both ends of the viscoelastic damper are respectively hinged to the cross bar and the inner wall of the steel structure cage.

[0015] Preferably, the steel structure vibration damping cylinder is a cylindrical structure, the steel plate is made of low-carbon steel material, and the steel structure cage is made of high-strength steel.

[0016] Preferably, a plurality of ventilation holes are evenly distributed on the steel plate, and a sealing plate is connected between the top end of the steel structure vibration damping cylinder and the outer wall of the elevator shaft.

[0017] Preferably, the height of the steel structure vibration damping cylinder is at least higher than 1 / 3 of the height of the elevator shaft, and the inner surface of the steel plate is provided with a thermal insulation layer.

[0018] The new steel structure elevator shaft has the following beneficial effects:

[0019] 1. The steel structure vibration damping cylinder of the new arrangement can, on the one hand, guide the wind direction through its cylindrical surface, and on the other hand, it can replace the elevator shaft in bearing the wind force when it is enclosed around the elevator shaft. Finally, the steel structure vibration damping cylinder is also connected to the elevator shaft through the vibration damping rod, which can effectively reduce the impact of strong winds on the elevator shaft, thereby protecting the safety of the building structure of old communities.

[0020] 2. This new model can reduce the heat conduction inside and outside the steel structure vibration damping cylinder by setting a thermal insulation layer. In summer, combined with the design of ventilation holes, it can reduce the temperature of the elevator shaft inside the steel structure vibration damping cylinder and improve the comfort of riding the elevator.

[0021] 3. The new steel structure vibration damping cylinder and the elevator shaft together constitute a brand-new steel structure elevator shaft. Compared with the traditional cubic elevator shaft, it has the characteristics of stable structure, vibration resistance and heat insulation, and is suitable for popularization and use.

[0029] The following embodiments may be understood as explaining part of the structure of the present invention individually, or may be understood as a combination of multiple embodiments to illustrate the structure of the present invention in a wider range.

[0030] Example 1

[0031] A steel structure elevator shaft, such as Figure 1 As shown, it includes a cement seat 1, an elevator shaft, and a steel structure vibration damping cylinder 2. The elevator shaft is arranged in the steel structure vibration damping cylinder 2. The bottom ends of the elevator shaft and the steel structure vibration damping cylinder 2 are both pre-buried in the cement seat 1. The cement seat 1 is pre-buried in the soil outside the building structure. A number of vibration damping rods 3 are evenly distributed between the outer wall of the elevator shaft and the inner wall of the steel structure vibration damping cylinder 2.

[0032] In this embodiment, by providing a steel structure vibration-damping cylinder, the elevator shaft can be subjected to vibration reduction and energy consumption, thereby preventing the vibration of the elevator shaft itself due to factors such as wind from having a significant impact on old buildings.

[0033] Example 2

[0034] like Figure 1 , 3As shown, the elevator shaft includes four vertical rods 4 distributed in a rectangular shape and arranged longitudinally, a plurality of installation frames 5 welded between adjacent vertical rods 4 and stacked up and down, and tempered glass 6 fixedly connected to the inner side of the installation frame 5. The bottom ends of the vertical rods 4 are pre-buried in the cement seat 1.

[0035] like Figure 2 As shown, a plurality of cross bars 7 are evenly distributed between adjacent vertical bars 4 and outside the tempered glass 6. Both ends of the cross bars 7 are welded to the corresponding vertical bars 4. The cross bars 7 on different sides of the elevator shaft are staggered.

[0036] like Figure 1 , 3 As shown, the inner wall of the steel structure vibration-damping cylinder 2 is connected to the relative cross bars 7 through a plurality of vibration-damping rods 3 .

[0037] In this embodiment, a plurality of cross bars 7 are provided and the cross bars 7 on different sides of the elevator shaft are arranged in a staggered manner, so that the steel structure vibration-damping cylinder can provide multi-directional support to the elevator shaft through the vibration-damping rods, thereby coping with vibrations from all directions.

[0038] Example 3

[0039] like Figure 4 As shown, the steel structure vibration damping cylinder 2 includes a cylindrical steel structure cage 9, a steel plate 10 welded in the gap of the steel structure cage 9, and the bottom end of the steel structure cage 9 is pre-buried in the cement seat 1; the vibration damping rod 3 is connected between the inner wall of the steel structure cage 9 and the cross bar 7.

[0040] Example 4

[0041] like Figure 1-4 As shown, the vibration damping rod 3 is made of shape memory alloy, and the two ends of the vibration damping rod 3 are welded to the cross bar 7 and the inner wall of the steel structure cage 9 respectively.

[0042] Example 5

[0043] like Figure 1-4 As shown, the vibration-damping rod 3 is a viscoelastic damper, and both ends of the viscoelastic damper are hinged to the cross bar 7 and the inner wall of the steel structure cage 9 respectively.

[0044] Example 6

[0045] like Figure 1-4 As shown, the steel structure vibration damping cylinder 2 is a cylindrical structure, the steel plate 10 is made of low-carbon steel material, and the steel structure cage is made of high-strength steel.

[0048] like Figure 4 As shown, the height of the steel structure vibration damping cylinder is at least higher than 1 / 3 of the height of the elevator shaft, and the inner surface of the steel plate is provided with a heat preservation layer. In specific implementation, it can be set to be equal to the height of the elevator shaft or higher than 1 / 3 of the height of the elevator shaft as needed. The heat conduction inside and outside the steel structure vibration damping cylinder can be reduced by providing a heat preservation layer. In summer, combined with the design of ventilation holes, the temperature of the elevator shaft inside the steel structure vibration damping cylinder can be reduced, thereby improving the comfort of riding the elevator.
