Description

[0001] The utility model relates to the technical field of tensile devices, and particularly relates to a gapless tensile device. Background Art

[0002] At present, the problem of the upper structure shape of high-rise buildings will lead to tension isolation bearings. Therefore, the method of increasing the diameter to share the vertical force for these bearings is not obvious. Therefore, a tensile device is installed near the bearings with serious tension here to assist in tensile force. There are many forms of tensile devices. Some use balls, cables, and steel. No matter which form, it cannot affect the normal displacement of the isolation bearing. Moreover, when the isolation bearing itself has tensile stress or exceeds the limit of 1 Mpa required by the specification, the tensile device can be quickly activated to offset part of the tensile force.

[0003] After the tensile device is installed, a compression gap will be generated after being subjected to the load of the upper structure. The current solution is to add a sleeve to the fixing bolt to solve the settlement gap problem. Another solution is to install the embedded part first and wait for the settlement of the overall structure to complete before installing the tensile device to eliminate the settlement gap problem of the tensile device. No matter which solution, it is relatively cumbersome, time-consuming and laborious. Summary of the Utility Model

[0026] Example

[0027] A gapless tensile device includes an upper structure, a lower structure, a tensile device 8, and a support part 14. The support part 14 is arranged on the lower structure to connect the lower end of the tensile device 8, the upper end of the tensile device 8 is connected to the upper structure, and an elastic body 6 for adapting to compression and compensating for gaps is provided above and / or below the tensile device 8.

[0028] In this solution, as Figure 1As shown in the figure, the upper structure includes frame beams 10 and upper frame columns 11, and the lower structure includes the basement top plate 9 and lower frame columns 12. The upper frame columns 11 are integrally cast with the frame beams 10, and the lower frame columns 12 are integrally cast with the basement top plate 9. The seismic isolation bearings 13 are arranged between the upper frame columns 11 and the lower frame columns 12, and the support part 14 is arranged on the basement top plate 9. The support part 14 is a concrete column integrally cast with the basement top plate 9.

[0029] The tensile device 8, as a key component connecting the upper structure and the lower structure, is responsible for transmitting and dispersing loads, and at the same time resisting the generated tensile force. The support part 14 is arranged on the lower structure and is used to fix and support the lower end of the tensile device 8 to ensure that the tensile device 8 can stably transmit loads. The elastomer 6 is a rubber body or a polyurethane body. In this embodiment, the elastomer 6 is arranged between the tensile device 8 and the support part 14 and is used to absorb and relieve the compression gap generated by compression. It can also protect the entire device from sudden impacts and damages, thus simply and quickly solving the problem of the compression gap of the tensile device 8, saving time and effort.

[0030] Furthermore, the tensile device 8 includes an upper plate 1, a lower plate 2 and a tensile body 3. The upper plate 1 is connected to the upper structure, the lower plate 2 is connected to the support part 14 and the elastomer 6 is arranged between the lower plate 2 and the support part 14. The tensile body 3 is located between the upper plate 1 and the lower plate 2. The upper end and the lower end of the tensile body 3 are respectively buckled with the upper plate 1 and the lower plate 2 to resist the vertical tensile force.

[0031] Specifically, as Figure 2 and Figure 3 shown in the figure, the upper plate 1 is connected to the upper structure through bolts 7. The upper plate 1 is responsible for effectively transmitting the loads of the upper structure to the tensile body 3. It usually has a large contact area and sufficient strength to ensure a firm connection with the upper structure and disperse the transmitted loads. The lower plate 2 is connected to the support part 14 through bolts 7. The tensile body 3 is located between the upper plate 1 and the lower plate 2 and is responsible for resisting the vertical tensile force and maintaining the stability of the structure. The upper end and the lower end of the tensile body 3 are respectively buckled with the upper plate 1 and the lower plate 2. This connection method helps to ensure the uniform transmission of loads and the stable operation of the tensile body 3. The elastomer 6 is arranged between the lower plate 2 and the support part 14 and is used to absorb and relieve the settlement gap generated by the tensile device 8 due to vertical loads. When the upper structure is subjected to vertical loads, the loads are transmitted to the tensile body 3 through the upper plate 1. The tensile body 3 resists the vertical tensile force through its high strength and stability and further transmits the loads to the lower plate 2. If the tensile device 8 sinks under compression, the elastomer 6 will be compressed, thereby absorbing and relieving the resulting displacement and tensile force, and then eliminating the compression gap.

[0032] Furthermore, there is a seismic isolation bearing 13 located on the outer side of the tensile device 8 between the upper structure and the lower structure.

[0033] Specifically, when the seismic isolation bearing 13 is arranged between the upper structure and the lower structure, the seismic isolation bearing 13 is usually placed on the outer side of the tensile device 8. The purpose of this is to utilize the seismic isolation performance of the seismic isolation bearing 13 to reduce the direct impact of the earthquake on the upper structure. At the same time, the tensile device 8 can provide additional support and stability to ensure the safety of the entire structure during the earthquake.

[0034] Furthermore, the bottom surface of the upper plate 1 has a pelvic cavity 5 with a downward opening, and the top surface of the lower plate 2 has a pelvic cavity 5 with an upward opening. A baffle 4 is provided at the open end of the pelvic cavity 5. The baffle 4 and the side wall of the pelvic cavity 5 form an L shape. The upper and lower ends of the tensile body 3 are respectively slidably assembled in the corresponding pelvic cavities 5.

[0035] Furthermore, the upper end of the tensile body 3 is T-shaped and the lower end is inverted T-shaped.

[0036] Furthermore, the upper end of the tensile body 3 and the upper plate 1 can be displaced relative to each other along the axis direction of the upper plate 1, and the lower end of the tensile body 3 and the lower plate 2 can be displaced relative to each other along the axis direction of the lower plate 2.

[0037] Furthermore, the axis of the upper plate 1 is perpendicular to the axis of the lower plate 2 in the horizontal plane.

[0038] Specifically, as Figure 2 and Figure 3 shown, the upper plate 1 and the lower plate 2 are respectively designed with pelvic cavities 5 with downward and upward openings. The pelvic cavities 5 provide a sliding assembly space for the tensile body 3. The design of the pelvic cavities 5 not only helps the stable installation of the tensile body 3 but also allows it to perform relative displacement within a certain range to adapt to the seismic isolation bearing 13. The open end of the pelvic cavity 5 is connected with a baffle 4 by screws. The baffle 4 and the side wall of the pelvic cavity 5 form an L-shaped structure. This design can prevent the tensile body 3 from slipping out of the pelvic cavity 5 during the sliding process, ensuring the overall stability of the tensile device 8. At the same time, the baffle 4 also plays a certain guiding role, enabling the tensile body 3 to slide along a predetermined path. The upper end of the tensile body 3 is designed as T-shaped and the lower end is inverted T-shaped. This special shape design enables the tensile body 3 to be more stably assembled in the pelvic cavities 5 of the upper and lower plates 2. At the same time, it increases the contact area with the upper and lower plates 2, improving the reliability of the connection. The upper and lower ends of the tensile body 3 are respectively slidably assembled in the corresponding pelvic cavities 5. The upper end of the tensile body 3 and the upper plate 1, as well as the lower end and the lower plate 2, can perform relative displacement along the axis directions of their respective plate members. The axis of the upper plate 1 is perpendicular to the axis of the lower plate 2 in the horizontal plane. This design helps to increase the stability of the tensile device 8 in the horizontal direction, preventing torsion or inclination caused by the action of horizontal forces. At the same time, the vertical axis direction also enables the tensile body 3 to distribute the load more evenly during the sliding process, improving the load-bearing capacity and safety of the entire device.

[0039] Installation method of the tensile device 8 in the present utility model: First, pour the support part 14 on the basement top slab 9, install the seismic isolation bearing 13 and the tensile device 8, then pour the superstructure. The bolts 7 of the tensile device 8 do not need to be tightened, just fix the position. After the subsequent compression settlement of the elastomer 6 is completed, then tighten them; after the upper floors are completely finished, it is necessary to monitor the overall settlement of the overall seismic isolation layer, generally 2 to 3 months after completion; after the upper floors complete the overall settlement, then tighten the bolts 7 of the tensile device 8, and control it within the initial gap range required by the design. The whole installation process is simple and fast, saving time and effort.

[0040] Tensile principle: Under minor or moderate earthquakes, the displacement of the seismic isolation layer (seismic isolation bearing 13) is not large, and the overturning force is not greater than the self-weight of the seismic isolation bearing 13. Therefore, the structure is in a compression-shear state, and the tensile device 8 does not work; under major earthquakes or near-major earthquakes, the displacement of the seismic isolation layer is relatively large, and the overturning force is greater than the self-weight of the seismic isolation bearing 13. Therefore, the seismic isolation bearing 13 and the tensile device 8 are in a tension-shear state, and the tensile device 8 and the bearing jointly resist tension.

[0041] The above are only the preferred embodiments of the present utility model, and do not impose any form of limitation on the present utility model. Based on the technical essence of the present utility model, any simple modifications, equivalent replacements, and improvements made to the above embodiments within the spirit and principles of the present utility model still fall within the protection scope of the technical solution of the present utility model.
