Description

Technical Field

[0001] This utility model relates to the field of rail transit engineering technology, and in particular to a pre-embedded component for rail steel structure. Background Technology

[0002] In rail transit construction, rail steel structures such as track beams, supports, and catenary columns need to be fixed in the concrete foundation using embedded parts.

[0003] The existing steel structure embedded parts generally use prefabricated steel plates to fix the embedded bolts to meet the positioning requirements of the embedded bolts. However, when there are multiple embedded parts of different sizes, multiple embedded parts need to be prefabricated to fix the steel plates. This makes it impossible to reuse the embedded parts multiple times, which not only wastes project costs but also does not meet the requirements of green construction.

[0004] An existing patent (publication number: CN213448903U) discloses a steel structure embedded component fastener. By using a combination of a fixing device and a connecting device, and with the help of a hexagonal nut, the embedded component is bolted to the site, fixing the fixing device and the embedded component into a whole to form a stable support. Moreover, the fixing device and the connecting device are fixed by a threaded connection, which allows the entire device to be reused multiple times, achieving the goal of green construction.

[0005] Existing patents offer solutions to the aforementioned problems, but their support effect is poor. In actual use, due to the lack of a supporting structure, the impact force generated during concrete filling cannot be offset, causing the embedded plate to tilt and shift. This results in the tilting of installed track beams and other items, seriously affecting the stability and safety of the building and reducing the practicality of the device.

[0006] To address this, a pre-embedded component for rail steel structure is proposed. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5 The present invention provides the following technical solution:

[0028] A pre-embedded component for a rail steel structure includes a fixing plate 1, a support component 2 fixedly connected to the bottom of the fixing plate 1, and a plurality of fixing holes 3 provided inside the fixing plate 1. A fixing component 4 is movably connected inside the fixing holes 3, and an anchor bolt 5 is fixedly connected to the bottom of the fixing component 4. The fixing component 4 includes a circular column 401, a connecting groove 402 provided at the top of the circular column 401, and positioning blocks 403 are slidably connected at the four corners of the bottom surface of the circular column 401.

[0029] The support assembly 2 includes a base 201. Rotating grooves 202 are provided at the four corners of the bottom of the base 201, and movable support legs 203 are rotatably connected inside the four rotating grooves 202. A connecting rod 204 is fixedly connected to the bottom of the base 201, and a moving block 205 is slidably connected to the surface of the connecting rod 204. A moving plate 206 is rotatably connected to the four corners of the bottom of the moving block 205, and the other end of the moving plate 206 is rotatably connected to the movable support leg 203.

[0030] In this embodiment: the circular plate 408 and the fixing bolt 409 work together to allow the circular column 401 to pass through the fixing hole 3, completing the initial fixing of the anchor bolt 5. Then, the fixing bolt 409 is rotated, causing it to move smoothly towards the moving circular plate 406 under the guidance of the connecting groove 402. This causes the moving circular plate 406 and the connecting plate 407 to move smoothly and compress the telescopic rod 404 and the spring 405, simultaneously pushing the positioning block 403 to move smoothly and accurately embed it into the fixing hole 3, forming a rigid lock. This facilitates the assembly of the embedded parts and improves the fixing assembly 4. The device is easy to use. Through the cooperation of the movable support leg 203 and the rotating groove 202, the movable support leg 203 can rotate smoothly in the rotating groove 202 under the constraint of the moving block 205 and the connecting rod 204. The angle of the movable support leg 203 can be adjusted to complete the unfolding of the movable support leg 203, increasing the contact area with the ground. At the same time, it can be used with the soil-breaking nail 8 to achieve strong anchoring, which can effectively disperse the impact force generated during the concrete filling process, avoid the phenomenon of tilting and displacement of the embedded parts, ensure the stability and safety of the building, and improve the stability of the device.

[0031] Specifically, such as Figure 5 As shown, a telescopic rod 404 is fixedly connected to the bottom of the inner wall of the connecting groove 402, and a spring 405 is provided on the surface of the telescopic rod 404. A movable circular plate 406 is fixedly connected to the top of the telescopic rod 404. A connecting plate 407 is movably connected to the four corners of the bottom of the movable circular plate 406, and the other end of the connecting plate 407 is movably connected to the positioning block 403.

[0032] Specifically, such as Figure 5As shown, a connecting circular plate 408 is fixedly connected to the bottom of the circular column 401, and the anchor bolt 5 is welded to the bottom of the connecting circular plate 408. A fixing bolt 409 is threadedly connected to the top of the circular column 401, and the bottom of the fixing bolt 409 extends into the interior of the connecting groove 402 and contacts the moving circular plate 406.

[0033] Specifically, such as Figure 5 As shown, each of the four corners of the bottom surface of the circular column 401 is provided with a movable hole 6 for use with the positioning block 403, and the movable hole 6 is connected to the connecting groove 402.

[0034] In this embodiment: the cooperation between the movable hole 6 and the connecting groove 402 allows the fixing bolt 409 to move smoothly within the connecting groove 402, simultaneously driving the movable circular plate 406 and the connecting plate 407 to move under the constraint of the connecting groove 402 and compressing the telescopic rod 404 and the spring 405. This, in turn, drives the positioning block 403 to move smoothly under the constraint of the movable hole 6, so that it is accurately embedded in the fixing hole 3, forming a mechanical lock and improving the ease of use of the fixing component 4.

[0035] Specifically, such as Figure 2 , Figure 4 As shown, the bottom of the movable support leg 203 is rotatably connected to a positioning plate 7, and the bottom of the positioning plate 7 is provided with several soil-breaking nails 8.

[0036] Specifically, such as Figure 4 As shown, the movable block 205 has a connecting hole 9 inside for use with the connecting rod 204, and the surface of the connecting rod 204 contacts the inner wall of the connecting hole 9. The front side of the movable block 205 is threaded with a positioning bolt 10, and the positioning bolt 10 extends into the interior of the connecting hole 9 on the side near the connecting rod 204.

[0037] In this embodiment: through the cooperation of the connecting rod 204 and the connecting hole 9, the moving block 205 moves smoothly under the constraint of the connecting rod 204, simultaneously restricting the movement of the moving plate 206 and the movable support leg 203, completing the unfolding of the movable support leg 203. At the same time, under the action of the positioning bolt 10, it passes through the moving block 205 and contacts the connecting rod 204, completing the fixation of the moving block 205, thereby fixing the movable support leg 203. Meanwhile, under the action of the positioning plate 7, it rotates smoothly under the restriction of the movable support leg 203. The angle of the positioning plate 7 can be flexibly adjusted, enabling the soil-breaking nail 8 to accurately break into the ground, achieving strong anchoring. It can effectively disperse and buffer external impact forces, avoid the phenomenon of tilting and displacement of the embedded parts, ensure the stability and safety of the building, and improve the ease of use of the support component 2.

[0038] Specifically, such as Figure 3As shown, positioning grooves 11 are provided at the four corners of the inner wall of the fixing hole 3 to cooperate with the positioning block 403, and the surface of the positioning block 403 is in contact with the inner wall of the positioning groove 11.

[0039] Specifically, such as Figure 2 , Figure 3 As shown, a fixing groove 12 is provided on the top of the fixing plate 1, a rubber buffer pad 13 is fixedly connected to the bottom of the inner wall of the fixing groove 12, and a magnetic block 14 is fixedly connected to the other end of the rubber buffer pad 13.

[0040] In this embodiment: the positioning block 403 and the positioning groove 11 work together to make the surface of the positioning block 403 contact the inner wall of the positioning groove 11 to form a mechanical lock. The fixing bolt 409 and the connecting circular plate 408 achieve double fastening, which can effectively resist external impact force and ensure that the anchor bolt 5 is tightly connected to the fixing plate 1, thus improving the stability of the device. Then, under the magnetic action of the magnetic block 14, the track component can be attracted and fixed to complete the pre-positioning, which facilitates the installation of subsequent components. At the same time, under the action of the rubber buffer pad 13, some of the impact force can be dispersed, reducing the impact force on the device and improving the ease of use of the device.

[0041] Working principle: When installing the embedded parts, firstly, the circular column 401 is smoothly passed through the fixing hole 3 to complete the initial positioning of the anchor bolt 5. Then, the fixing bolt 409 is aligned with the connecting groove 402 and manually tightened to make it move smoothly down along the connecting groove 402. This drives the moving circular plate 406 and the connecting plate 407 to move smoothly and compress the telescopic rod 404 and the spring 405. Simultaneously, the positioning block 403 is pushed to move smoothly, making it accurately embedded in the positioning groove 11, forming a rigid locking structure. This, together with the fixing bolt 409, forms a double fixation, realizing the installation of the anchor bolt 5. When disassembling, the fixing bolt 409 is rotated in the opposite direction to remove it. Under the action of the spring 405 and the telescopic rod 404, the anchor bolt 5 is lifted out of the groove. The movable plate 206 and the positioning block 403 are reset, releasing the fixed state of the fixing component 4. After the anchor bolt 5 is connected to the fixing plate 1, the movable support leg 203 is manually moved so that it rotates smoothly under the constraint of the movable block 205 and the connecting rod 204. The positioning bolt 10 can be used to fix the movable block 205, completing the unfolding of the movable support leg 203. At the same time, the positioning plate 7 is rotated so that the soil-breaking nail 8 can be accurately driven into the ground to achieve strong anchoring. This can effectively disperse the impact force generated during the concrete filling process, avoid the phenomenon of tilting and displacement of the embedded parts, and ensure the stability and safety of the building. After the embedded parts are placed, concrete is filled to complete the entire embedded part installation process.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
