Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of anchoring pieces, in particular to an underground station structure anchoring device. Background Art
[0002] Underground stations are a common type of railway station. With the large-scale development of underground railways, the number of underground stations has increased. Underground stations have many disadvantages, such as difficult construction, high construction costs, many safety hazards, long operation time, inconvenient entry and exit, poor air circulation, small expansion space, and easy water accumulation. They are themselves a large and complex construction project. The direct reason for choosing an underground station is that the track route where the station is located is underground, so an underground station is a last resort. However, underground stations have many special uses, such as sheltering from wind and rain, preparing for air defense, and saving ground space.
[0003] When constructing an underground station, the construction of the insulation layer of the underground station is particularly important. In the prior art, when constructing the insulation layer, a plurality of anchors are usually used to fix the insulation board in the underground space. The traditional anchor is a combination of an anchor rod and a pressure plate, and the insulation board is directly pressed and fixed by the pressure plate. However, during the use of the underground station, not only will the underground train cause vibration to the underground station stalks when it is running, but cars on the ground will also transmit vibration to the underground station structure when passing over the underground station. Therefore, the vibration wave to which the underground station structure is subjected is much larger than that to traditional ground buildings. Under the action of this vibration force, since the existing anchors are only fixed by pressing, this method has a poor limiting effect on the insulation board, and the insulation board is easily offset under the action of various vibration forces, which may cause the gap between adjacent insulation boards to become larger, thereby making the insulation performance of the underground station structure worse. Utility Model Content
[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose an underground station structure anchoring device, thereby solving the problems of the prior art.
[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0006] A structural anchoring device for an underground station comprises a first pressing plate and a second pressing plate. The first pressing plate is provided with a first anchoring hole, the second pressing plate is provided with a second anchoring hole, the first pressing plate is fixedly connected to a first limiting plate, the first limiting plate passes through a giving way groove of the second pressing plate, and the second pressing plate is detachably connected to the second limiting plate.
[0007] Furthermore, a sliding groove is provided on the second pressing plate, a sliding block is slidably connected in the sliding groove, and the second limiting plate is fixed on the sliding block.
[0008] Furthermore, the first pressing plate and the second pressing plate are detachably fixed together.
[0009] Furthermore, a first conical portion is provided at one end of the first limiting plate.
[0010] Furthermore, a second conical portion is provided at one end of the second limiting plate.
[0011] The beneficial effects of the utility model are as follows: an underground station structure anchoring device provided by the utility model limits the corners of four insulation boards through a second limiting plate and a first limiting plate, and the second limiting plate and the first limiting plate are both inserted into the gaps between the insulation boards, so that anchoring devices are arranged at the four corners of the insulation boards, and the insulation boards are limited from four directions, completely restricting the degrees of freedom of the insulation boards, ensuring that the insulation boards will not be offset due to vibration force during use.

[0016] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0017] like Figure 1-3 As shown, the utility model provides an underground station structure anchoring device, including a first pressing plate 1 and a second pressing plate 2, the first pressing plate 1 and the second pressing plate 2 can be circular plates or rectangular plates, and the first pressing plate 1 and the second pressing plate 2 can be detachably fixed together. The specific detachable fixing is as follows, see Figure 2 and Figure 3, a countersunk hole 14 is provided on the first pressing plate 1, and a threaded hole 27 is provided on the second pressing plate 2, so that a screw is passed through the countersunk hole 14 and threadedly connected in the threaded hole 27, thereby realizing a detachable connection between the first pressing plate 1 and the second pressing plate 2. A first anchoring hole 13 is provided on the first pressing plate 1, and a second anchoring hole 25 is provided on the second pressing plate 2. When the first pressing plate 1 and the second pressing plate 2 are fixed together, the first anchoring hole 13 and the second anchoring hole 25 are coaxial, and at this time, the rivet can pass through the first anchoring hole 13 and the second anchoring hole 25 and be fixed on the structural layer of the underground station.
[0018] In order to limit the insulation board in multiple directions, two first limiting plates 11 are fixedly connected to the first pressure plate 1. The two first limiting plates 11 are symmetrically arranged with the first anchor hole 13 as the center, and the two first limiting plates 11 are on the same plane. A first conical portion 12 is provided at one end of the first limiting plate 11. The purpose of providing the first conical portion 12 is to facilitate the insertion of the first limiting plate 11 into the gap between two adjacent insulation boards.
[0019] The first limit plate 11 passes through the give way groove 26 of the second pressure plate 2. On the one hand, this arrangement allows the first limit plate 11 to give way through the give way groove 26, so that the second pressure plate 2 will not interfere with the first limit plate 11. On the other hand, the first limit plate 11 is inserted and matched in the give way groove 26 to form a positioning between the first pressure plate 1 and the second pressure plate 2, thereby preventing position displacement when the first pressure plate 1 and the second pressure plate 2 are connected together.
[0020] The second limiting plate 23 is detachably connected to the second pressing plate 2. A second conical portion 24 is provided at one end of the second limiting plate 23. The purpose of providing the second conical portion 24 is to facilitate the insertion of the second limiting plate 23 into the gap between two adjacent insulation plates. At the same time, the second limiting plate 23 is perpendicular to the first limiting plate 11. A sliding groove 21 is provided on the second pressing plate 2. A slider 22 is slidably connected in the sliding groove 21. The second limiting plate 23 is fixed on the slider 22. During use, whether to install the second limiting plate 23 is selected according to actual usage.
[0021] During use, after the first pressing plate 1 and the second pressing plate 2 are fixed together, and the second limiting plate 23 is installed on the second pressing plate 2, the second limiting plate 23 and the first limiting plate 11 are arranged in a "cross" shape, see Figure 4, so that the corners of the four insulation boards 100 can be limited by the second limiting plate 23 and the first limiting plate 11, and the second limiting plate 23 and the first limiting plate 11 are inserted into the gap 200 between the insulation boards 100. In this way, anchoring devices are set at the four corners of the insulation board to limit the insulation board from four directions, completely restricting the degree of freedom of the insulation board, and ensuring that the insulation board will not be offset due to vibration force during use. At the same time, in order to increase the anchoring points, multiple anchoring points are set at the gap 200 between the insulation boards 100. At this time, there are two ways to install. The first way is to separate the first pressing plate 1 from the second pressing plate 2, and use the first pressing plate 1 or the second pressing plate 2 alone for anchoring. At this time, the second limiting plate 23 or the first limiting plate 11 is inserted into the gap 200, so that the insulation board can still be limited. Another method is to remove the second limiting plate 23, so that only the first limiting plate remains, and insert the first limiting plate into the gap 200 to limit the insulation board. The choice of the two methods is based on the thickness of the insulation board and the distance between adjacent anchor points. When the thickness of the insulation board is too large or the distance between adjacent anchor points is too large, the first method is selected, otherwise the second method is selected.
