Description

Technical Field

[0001] This utility model belongs to the technical field of pipe fixing devices, and in particular relates to a fixing device for bridge pipes. Background Technology

[0002] In bridge construction, the bridge deck drainage system is an important component to ensure the durability of the bridge structure and traffic safety. Therefore, after the bridge construction is completed, drainage pipes are installed in places such as the bridge beams and slabs to guide rainwater and snowmelt from the bridge deck to drain out in a timely manner, preventing water from seeping in and corroding the bridge structure or affecting traffic safety.

[0003] Currently, bridge drainage pipes are mostly fixed using clamps, which are metal clamps used to secure the pipes to the bridge beams. This installation method has advantages such as simple construction and low cost. However, during long-term use, due to factors such as vehicle vibration, wind load, temperature deformation, and slight displacement of the bridge structure itself, the clamps are prone to loosening, slippage, or even falling off; thus, the bridge drainage pipes are prone to loosening after being fixed. Utility Model Content

[0004] The purpose of this utility model is to provide a fixing device for bridge pipelines, so that the bridge drainage pipelines will not loosen as much as possible after fixing.

[0005] The aforementioned bridge pipeline fixing device includes a vertically arranged clamp body, a horizontally arranged fixing plate on the front side of the clamp body, and a plurality of first mounting holes that are interconnected front and back on the fixing plate; the middle part of the fixing plate has a U-shaped cross-section with the opening facing backward; the fixing plate is provided with a connecting component for connecting its middle part to the mounting hole position of the clamp body.

[0006] Furthermore, the connecting assembly includes a second mounting hole, which is connected front to back and located in the middle part of the fixing plate; the center lines of the second mounting hole and the mounting hole on the clamp body are on the same straight line; the same expansion bolt is inserted into the second mounting hole and the mounting hole on the clamp body.

[0007] Furthermore, a retaining ring is fixed to the rear side wall of the middle portion of the fixing plate to facilitate positioning between the second mounting hole and the mounting hole on the clamp body.

[0008] Furthermore, the clamp body is a U-shaped clamp.

[0009] Furthermore, fixing plates are provided on both the upper and lower wing plates of the U-shaped clamp.

[0010] Furthermore, the fixing plate is made of carbon steel.

[0011] Furthermore, the clamp body is a circular clamp.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This utility model features a fixing plate on the front side of the clamp body, with several first mounting holes that communicate with each other. The middle portion of the fixing plate has a U-shaped cross-section with the opening facing backward. The fixing plate is equipped with a connecting component for connecting its middle portion to the mounting holes of the clamp body. After the fixing plate is fixed to the clamp body by the connecting component, because the fixing plate has several first mounting holes, expansion bolts can be driven into the bridge beam through these holes to achieve multi-point fixing, increasing the stability of the clamp during fixing and preventing loosening and slippage when using the clamp on the bridge, which could lead to loosening of the bridge drainage pipes after fixing.

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

[0024] Example 1

[0025] This embodiment describes a fixing device for bridge pipelines, such as... Figure 1 , Figure 2 and Figure 5 As shown, the clamp body is vertically arranged and is a U-shaped clamp 1. The U-shaped clamp 1 consists of a clamp plate 1.1 and two upper and lower flanges 1.2. The clamp plate 1.1 is the main part of the U-shaped clamp and is usually made of metal. It is used to hold or clamp the drainage pipe. The flanges 1.2 are located on both sides of the clamp plate and play a role in strengthening and fixing. Each flange 1.2 has a mounting hole. When using the U-shaped clamp 1 to fix the drainage pipe, first place the drainage pipe inside the U-shaped clamp 1, and then drive expansion bolts 6 into the bridge beam through the mounting holes on the flanges 1.2. This will fix the flanges 1.2 to the bridge beam. Since the drainage pipe is located inside the U-shaped clamp 1, the purpose of fixing the drainage pipe can be achieved.

[0026] like Figure 1 As shown, a fixing plate 3 is horizontally arranged on the front side of the clamp body, and the fixing plate 3 has several first mounting holes 2 that are interconnected front and rear; as Figure 1 In terms of orientation, when the clamp body is a U-shaped clamp 1, the U-shaped clamp 1 is vertically set and the fixing plate 3 is horizontally set, so the U-shaped clamp 1 and the fixing plate 3 are perpendicular to each other; because the fixing plate 3 has a first mounting hole 2, the expansion bolt 6 can be driven into the bridge beam plate through the first mounting hole 2 to fix the fixing plate 3 to the bridge beam plate; because there are several first mounting holes 2, the fixing plate 3 can be fixed to the bridge beam plate more stably; because the fixing plate 3 and the U-shaped clamp 1 are perpendicular to each other, when the first mounting hole 2 is located on the left and right parts of the fixing plate 3, the U-shaped clamp 1 will not block the first mounting hole 2 on the fixing plate 3, so it is convenient to drive the expansion bolt 6 into the first mounting hole 2;

[0027] like Figures 1-5 As shown, the middle portion of the fixing plate 3 has a U-shaped cross-section with the opening facing backward; the structure of the fixing plate 3 is as follows. Figure 3 As can be seen from the orientation, it is preferable that its top is on the same straight line as the top of the wing plate 1.2, with the bottom of the middle part concave downwards in a "U" shape; when the clamp body is a U-shaped clamp 1, the "U" shape of the fixing plate 3 is designed according to the size of the wing plate 1.2, so that the size of the "U" shape in the middle part of the fixing plate 3 is slightly larger than the length and width of the wing plate 1.2, according to Figure 3 As can be seen from the orientation, the "U"-shaped structure in the middle of the fixing plate 3 can fit snugly against the outer side of the wing plate 1.2; therefore, the above design facilitates the clamping of the fixing plate 3 to the mounting hole position on the wing plate 1.2; corresponding to Figure 3 When fixing the wing plate 1.2 to the bridge beam plate, the top of the fixing plate 3 and the top of the wing plate 1.2 are the side walls that contact the bridge beam plate. Since the tops of the fixing plate 3 and the wing plate 1.2 are on the same straight line, the fixing plate 3, except for the middle part, can directly contact the bridge beam plate. After contact, it is convenient to drive the expansion bolt 6 into the bridge beam plate from the position of the first mounting hole 2, thus making it easier to fix the fixing plate 3 to the bridge beam plate.

[0028] like Figure 1 , Figure 2 and Figure 5 As shown, the fixing plate 3 is provided with a second mounting hole 4, which is connected front and rear and located in the middle part of the fixing plate 3; the center line of the second mounting hole 4 and the mounting hole on the clamp body are on the same straight line; the same expansion bolt 6 is installed in the second mounting hole 4 and the mounting hole on the clamp body; this section of the scheme constitutes a connecting component for connecting the middle part of the fixing plate 3 to the mounting hole position of the clamp body; when the clamp body is a U-shaped clamp 1, the mounting hole on the clamp body is located on the wing plate 1.2; in use, firstly, the second mounting hole 4 on the fixing plate 3 is aligned with the position of the mounting hole on the wing plate 1.2, and then the expansion bolt 6 is driven into the bridge beam plate from the position of the second mounting hole 4 and the mounting hole. This not only fixes the fixing plate 3 to the position of the mounting hole on the wing plate 1.2, but also fixes the wing plate 1.2 and the fixing plate 3. This design, fixed to the bridge beam, serves a dual purpose, eliminating the need to first fix the fixing plate 3 to the wing plate 1.2 and then fix the wing plate 1.2 to the bridge beam, reducing operational steps and increasing convenience during use. After the wing plate 1.2 and fixing plate 3 are fixed to the bridge beam, expansion bolts 6 can be driven into the bridge beam through the first mounting hole 2 on the fixing plate 3, achieving multi-point fixing. Traditionally, when the U-shaped clamp 1 is installed on the bridge beam, expansion bolts 6 are driven into the bridge beam through the mounting hole on the wing plate 1.2. Therefore, compared to the traditional method of fixing with only one mounting hole, this design improves the stability of the wing plate 1.2 during use, thereby improving the stability of the drainage pipe fixing and preventing the drainage pipe from loosening after fixing.

[0029] In practice, the expansion bolt 6 in the connecting assembly can also be an expansion screw;

[0030] like Figure 1 , Figure 3 , Figure 4 and Figure 5As shown, a retaining ring 5 is fixed to the rear side wall of the middle part of the fixing plate 3 to facilitate positioning between the second mounting hole 4 and the mounting hole on the clamp body; when the clamp body is a U-shaped clamp 1, the retaining ring 5 specifically achieves positioning according to... Figure 4 and Figure 5 In the center position, the retaining ring 5 is fixed at the top of the middle position of the fixing plate 3. The bottom of the wing plate 1.2 has an annular groove for the retaining ring 5 to be inserted. When the retaining ring 5 is engaged in the annular groove, the center lines of the second mounting hole 4 and the mounting hole on the wing plate 1.2 are on the same straight line. In use, after the retaining ring 5 is put into the annular groove, it is easy to align the mounting hole on the wing plate 1.2 with the second mounting hole 4, and it is easy to insert the expansion bolt 6 through the aligned hole, thus increasing the convenience of use.

[0031] like Figure 1 As shown, fixing plates 3 are provided on the upper and lower wing plates 1.2 of the U-shaped clamp 1. Because the U-shaped clamp 1 has two wing plates 1.2, and the positions of the two wing plates 1.2 are equipped with mounting holes, the design of the two fixing plates 3 can strengthen the fixing of the upper and lower wing plates 1.2 respectively, and further improve the stability of the fixed drainage pipe.

[0032] The fixing plate 3 is made of carbon steel. Carbon steel has many advantages, such as high strength and strong load-bearing capacity, making it suitable for heavy-duty scenarios (such as pipe fixing and bridge structures).

[0033] In practical use: When the clamp body is a U-shaped clamp 1, first place the drainage pipe inside the clamp plate 1.1 of the U-shaped clamp 1. Then, align the second mounting hole 4 on the fixing plate 3 with the mounting hole on the wing plate 1.2. Next, drive expansion bolts 6 into the bridge beam plate from the second mounting hole 4 and the mounting hole, thus fixing the wing plate 1.2 and the fixing plate 3 to the bridge beam plate. Then, drive multiple expansion bolts 6 into the bridge beam plate again from the first mounting hole 2 on the fixing plate 3. Because the drainage pipe is located inside the clamp plate 1.1, once the clamp plate 1.1 is fixed to the bridge beam plate via the wing plate 1.2, the drainage pipe can be fixed to the bridge beam plate. When fixing the wing plate 1.2, because the wing plate 1.2 is clamped with the fixing plate 3, and the fixing plate 3 is provided with several first mounting holes 2, the design of driving expansion bolts 6 into the bridge beam plate again from the position of the first mounting holes 2 can achieve the purpose of auxiliary fixing and increase the stability of the wing plate 1.2 during fixing; thus avoiding the problem that the clamps are prone to loosening, slippage or even falling off when fixing bridge pipes due to factors such as vehicle vibration, wind load, temperature deformation and the slight displacement of the bridge structure itself; therefore, this design avoids the problem of loosening of bridge drainage pipes after being fixed by clamps through multi-point fixing.

[0034] Example 2

[0035] This embodiment will further illustrate the technology. As Figures 6-8 shown, the hoop body is a circular hoop 7; the circular hoop 7 is mainly composed of a hoop band 7.1 and fastening bolts; according to Figure 8 the orientation in, there are two hoop bands 7.1 on the left and right. A circular structure is formed between the two hoop bands 7.1 for wrapping around the outer periphery of the drainage pipe to provide fastening force; the fastening bolts are used to connect the two ends of the hoop band 7.1 to generate a clamping force by tightening; when the hoop body corresponds to the circular hoop 7, the middle position of the left hoop band 7.1 is in a "C" - shaped structure, and the mounting holes on the hoop body are located at the position of the "C" - shaped structure and are connected left and right; when the traditional circular hoop 7 is installed on the bridge beam slab, only expansion bolts 6 are driven into the bridge beam slab at the position of the mounting holes in the "C" - shaped structure; in this design, when the circular hoop 7 is fixed to the bridge beam slab in cooperation with the fixing plate 3, first align the second mounting holes 4 on the fixing plate 3 with the mounting holes on the hoop band 7.1, then drive expansion bolts 6 into the bridge beam slab from the positions of the second mounting holes 4 and the mounting holes, so that the hoop band 7.1 and the fixing plate 3 can be fixed to the bridge beam slab. Then drive expansion bolts 6 into the bridge beam slab again from the position of the first mounting holes 2 on the fixing plate 3 to achieve the purpose of multi - point fixation; finally, place the drainage pipe between the two hoop bands 7.1 on the left and right and fix them together with fastening screws; during the above - mentioned operation process, compared with the traditional method with only one mounting hole for fixation, this design can improve the stability of the hoop band 7.1 during fixation, thereby improving the stability of the drainage pipe during fixation; avoiding the problem that the bridge drainage pipe is prone to looseness after fixation; after fixation, as Figure 8 the orientation in can be seen; the principle of the cooperation between the fixing plate 3 and the hoop band 7.1 is the same as the principle of the cooperation between the fixing plate 3 and the wing plate 1.2 on the U - shaped hoop 1, so it will not be elaborated too much.

[0036] When using the fixing plate 3 for the corresponding circular hoop 7, it is preferably fixed with a snap ring 5 on the fixing plate 3, and an annular groove is also provided at the position of the mounting hole of the hoop band 7.1. The cooperation mode between the snap ring 5 and the annular groove is the same as that when using the U - shaped hoop 1, so it will not be elaborated. Therefore, through the above design, it is also convenient to align the second mounting holes 4 on the fixing plate 3 with the mounting holes on the hoop band 7.1.

[0037] In the actual operation process, as long as the hoop body is installed on an object (bridge beam slab) with one mounting hole, this design's fixing plate 3 can be applicable to hoop bodies of different structures, not only applicable to the U - shaped hoop 1 and the circular hoop 7, but also applicable to flat - iron hoops and double - top - hat hoops, thus increasing the practicality during the use of this design.
