Description

Technical Field

[0001] This utility model relates to the technical field of highway noise reduction facilities, specifically a spliced ​​sound barrier. Background Technology

[0002] With the rapid development of highway transportation, noise pollution has become a prominent environmental problem along the route. Traditional sound barriers are mostly installed using fixed integral structures or bolted connections, which have obvious drawbacks. For example, they have low installation efficiency, require on-site welding or individual bolt tightening, have long construction cycles, affect traffic flow, or have poor terrain adaptability, with the length of the support structure not being adjustable, making it difficult to cope with uneven roadbeds, and easily leading to barrier tilting or loose connections. In addition, when a sound barrier is partially damaged, it needs to be completely disassembled and replaced, which is not economical. Therefore, there is an urgent need for a sound barrier structure that can be quickly assembled and is easy to maintain. Utility Model Content

[0003] The purpose of this invention is to provide a modular sound barrier that improves installation efficiency, facilitates partial replacement, and reduces costs.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: a splicing sound barrier, comprising a barrier part, a connecting part, and a supporting part;

[0005] The barrier includes a barrier plate and a mounting base fixedly disposed at the bottom of the barrier plate, wherein a T-shaped groove is provided on the bottom surface of the mounting base;

[0006] The connecting part includes a splicing frame, with splicing grooves on both sides of the splicing frame, and a mounting groove connected to the bottom of the splicing groove; a T-shaped slide rail is fixed in one of the mounting grooves, and a short slide rail is fixed in the other mounting groove; the T-shaped slide rail and the short slide rail can be inserted into the T-shaped grooves of adjacent barrier parts respectively, so that the side of the barrier panel can be slidably inserted into the splicing groove;

[0007] One end of the support is fixed to the splicing frame, and the other end is fixed to the ground. The support is also telescopic.

[0009] In a further technical solution, the support part includes a first support rod and a second support rod. The top end of the first support rod is used to connect and fix to the splicing frame, and the bottom end of the second support rod is used to fix to the ground. The first support rod and the second support rod are telescopically connected.

[0010] In a further technical solution, the length of the T-shaped slide rail is greater than the length of the short slide rail, and the sum of the total lengths of the T-shaped slide rail and the short slide rail is equal to the length of the T-shaped groove.

[0011] A further technical solution is provided, wherein the first support rod has a slot, and the second support rod has a plug rod fixed thereon, the plug rod being inserted into the slot; the first support rod has a fastening threaded hole, into which an adjusting bolt can be inserted, and the adjusting bolt being screwed in can tighten the plug rod.

[0012] In a further technical solution, a splicing hole is provided at the top of the first support rod, and a splicing threaded hole is provided on the splicing frame. The splicing bolt passes through the splicing hole and is screwed into the splicing threaded hole to fix the first support rod to the splicing frame.

[0013] In a further technical solution, a fixing hole is provided on the second support rod, and a ground nail is driven into the ground through the fixing hole to fix the second support rod to the ground.

[0014] In a further technical solution, the bottom of the splicing frame is provided with holes for fixing bolts to pass through, and the splicing frame is fixed to the ground by the fixing bolts.

[0017] In summary, this utility model has the following beneficial effects:

[0018] By using the sliding fit between the T-shaped slide rail and the T-shaped groove, the barrier panel and the splicing frame can be quickly connected, reducing the amount of bolts used and improving the construction splicing efficiency.

[0019] Rubber strips are embedded in the splicing grooves to effectively absorb the vibration energy of the barrier panels, reduce collision noise caused by wind, and improve the noise reduction and vibration damping effect.

[0020] The support section adopts a telescopic structure of insert rods and slots, which is locked with adjusting bolts. The height difference can be flexibly adjusted to adapt to complex terrains such as slopes and soft foundations, and to achieve terrain-adaptive adjustment support.

[0021] Each barrier panel can be disassembled and replaced independently, eliminating the need for complete removal, thus reducing maintenance costs and improving ease of maintenance. Attached Figure Description

[0039] like Figures 1-10 The illustrated modular sound barrier includes a barrier section 100, a connecting section 200, a rubber strip 300, and a support section 400. The barrier section 100 includes a barrier panel 101, the top of which slopes towards the roadside. A mounting base 102 is provided at the bottom of the barrier panel 101, and the mounting base 102 is fixed to the barrier panel 101. This can be a single, integrated design. Figure 3 The mounting base 102 has a T-shaped groove 103 on its bottom surface, and the T-shaped groove 103 is in the shape of a "T".

[0040] In one embodiment, such as Figure 4 , Figure 6 and Figure 7 As shown, the connecting part 200 includes a splicing frame 201. Splicing grooves 204 are provided on both sides of the splicing frame 201. A mounting groove 203 is provided at the bottom of each splicing groove 204. A T-shaped slide rail 202 is fixed in one of the mounting grooves 203, and a short slide rail 205 is fixed in the other mounting groove 203. The T-shaped slide rail 202 and the short slide rail 205 form a "T" shape. The length of the T-shaped slide rail 202 is greater than that of the short slide rail 205. The length of 05, the sum of the total length of the T-shaped slide rail 202 and the short slide rail 205 is the same as the sum of the lengths of the T-shaped groove 103, the T-shaped slide rail 202 and the short slide rail 205 can be inserted into the T-shaped groove 103, so that the barrier plate 101 can slide on the T-shaped slide rail 202 and the short slide rail 205, so that the barrier part 100 and the connecting part 200 are slidably spliced ​​together, and the side of the barrier plate 101 is inserted into the splicing groove 204.

[0041] In one embodiment, the splicing groove 204 has an embedding groove 206 on both the side walls near the road and away from the road. A rubber strip 300 is embedded in the embedding groove 206. The rubber strip 300 can be made of rubber to reduce the noise generated by the shaking of the barrier plate 101 after it is inserted into the splicing groove 204. For example, when the wind blows, it may cause the barrier plate 101 to vibrate. The rubber strip 300 can absorb some of the vibration and reduce the noise.

[0042] In one embodiment, the support 400 includes a first support rod 401 and a second support rod 402, which can be spliced ​​together. Specifically, the first support rod 401 has a slot 406, and the second support rod 402 has a plug rod 405 fixed thereon. The plug rod 405 can be inserted into the slot 406. The first support rod 401 has a fastening threaded hole 407, which is threaded. After inserting an adjusting bolt 409, the plug rod 405 can be tightened, thus fixing the second support rod 402 and the first support rod 401. By inserting the plug rod 405 into the slot 406, the length of the support 400 can be adjusted to adapt to the length requirements of different installation terrain environments.

[0043] In one embodiment, the top end of the first support rod 401 can be attached to the side of the splicing frame 201 facing away from the road. A splicing hole 408 is also provided on the first support rod 401, and a splicing threaded hole 208 is also provided on the splicing frame 201. The splicing threaded hole 208 has threads inside. By inserting the splicing bolt 410 into the splicing hole 408 and tightening it into the splicing threaded hole 208, the first support rod 401 and the splicing frame 201 are fixed. In another embodiment, two splicing holes 408 and two splicing threaded holes 208 can be provided to increase the stability of the connection between the first support rod 401 and the splicing frame 201.

[0044] In one embodiment, the second support rod 402 has a fixing hole 404 for inserting a ground nail 403 to fix the second support rod 402 to the ground. The ground can be hardened by laying cement, and then the ground nail 403 can be inserted. The ground nail 403 can be an expansion screw to fix the second support rod 402 to the ground.

[0045] In one embodiment, the bottom of the splicing frame 201 can be fixed to the ground by at least fixing bolts 207.

[0046] The method for assembling a modular sound barrier according to this application is as follows:

[0047] First, cement was laid on both sides of the road.

[0048] Next, one of the splicing frames 201 is fixed in place. For ease of explanation later, this splicing frame 201 will be referred to as the first splicing frame 201. It is fixed to the ground with two fixing bolts 207. The T-slot 103 and the T-rail 202 are aligned so that the T-rail 202 is inserted into the T-slot 103. Then, the barrier plate 101 is pushed so that it slides along the T-rail 202, thereby inserting one side of the barrier plate 101 into the splicing groove 204, completing the docking of the barrier plate 101 with the first splicing frame 201. Then, the other splicing frame 201 is... This is defined here as the second splicing frame 201. The second splicing frame 201 is assembled with the other side of the barrier plate 101. The short slide rail 205 of the second connecting part 200 is inserted into the T-slot 103. The second splicing frame 201 is pushed so that the splicing slot 204 of the second splicing frame 201 is aligned with the other side of the barrier plate 101. After installation, the second splicing frame 201 is fixed to the ground with fixing bolts 207. Then, the second barrier plate 101 and the third splicing frame 201 are installed. The splicing is carried out in sequence according to the above splicing method.

[0049] Finally, the support part 400 and the connecting part 200 are assembled together. The length of the assembled first support rod 401 and second support rod 402 is adjusted according to the terrain. For example, if the ground where the second support rod 402 is installed is lower than the ground where the splicing frame 201 is installed, the splicing length of the second support rod 402 and the first support rod 401 can be adjusted appropriately. This means inserting the insertion rod 405 into the slot 406 by a shorter portion, so that the bottom end of the second support rod 402 can contact the ground. At this point, the first support rod... 401 is spliced ​​with the splicing frame 201 by inserting the splicing bolt 410 into the splicing hole 408 and then into the splicing threaded hole 208 and tightening it to fix the first support rod 401 to the splicing frame 201. Then, the insert rod 405 is inserted into the slot 406, with the bottom end of the insert rod 405 abutting against the ground. The ground nail 403 is inserted into the fixing hole 404 and driven into the ground. Then, the adjusting bolt 409 is inserted into the fastening threaded hole 407 to tighten the insert rod 405. At this time, the adjusting bolt 409 is tightened to complete the assembly.
