Description

Technical Field

[0001] This utility model relates to the field of highway reconstruction technology, and more specifically, to a protective structure for the reconstruction of old asphalt pavements. Background Technology

[0002] Road reconstruction refers to the large-scale renovation of existing highways to improve their technical standards or technical grade. Asphalt pavement refers to various types of pavement constructed by mixing road asphalt materials into mineral materials. Asphalt binder improves the ability of paving aggregates to resist damage to the pavement from traffic and natural factors, making the pavement smooth, dust-free, impermeable, and durable. Therefore, asphalt pavement is one of the most widely used high-grade pavements in road construction.

[0003] Existing asphalt pavement reconstruction and protection typically employs multiple guardrails. However, the lack of a concrete connecting structure between adjacent guardrails makes them prone to shifting, thus compromising the overall structure of the entire row of guardrails and disrupting normal road operation.

[0004] A search revealed a Chinese patent with publication number CN218347063U that discloses a protective mechanism for the reconstruction of old asphalt pavements. This device solves the problem in the prior art where there is no specific connecting structure between two adjacent guardrails, which easily causes the guardrails on the road surface to shift, thereby damaging the overall structure of the entire row of guardrails and affecting normal road operation.

[0005] However, in actual use, the above-mentioned protective mechanisms often encounter the problem of inconsistent standards between old and new road sections during the renovation of old roads. The existing guardrails have fixed lengths, which means that the guardrails and road lengths cannot be accurately matched. This results in the guardrail posts on both sides not being aligned, reducing the applicability of the guardrail installation. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, this utility model provides a protective structure for the reconstruction of old asphalt pavement, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: The asphalt pavement reconstruction and protection structure includes two columns, each with a base fixedly connected to its bottom end, and a base column fixedly connected to the bottom end of each base. A telescopic mechanism is provided between the two columns. The telescopic mechanism includes a connecting part between the columns. The connecting part includes two support rods and two positioning frames, with the two positioning frames symmetrically arranged on both sides of the two support rods. Support rods two and three are fixedly connected between the two positioning frames. Support rods two and three are sequentially arranged between and on the bottom sides of the two support rods one. Each end of each support rod one is fitted with a crossbeam one and a crossbeam three from top to bottom. Both crossbeams one and three have a sliding groove one on their inner sides for sliding of the two support rods one, and both support rods two and three have a sliding groove two on their inner sides. Both ends of support rod 2 and support rod 3 are slidably connected to crossbeam 2. Crossbeam 1 and two crossbeam 3 are symmetrically arranged at both ends of two support rod 1. Multiple crossbeam 2 are symmetrically arranged at both ends of support rod 2 and support rod 3. One side of each of the two crossbeam 3 is threadedly connected to bolt 1, and the end of bolt 1 extends to the inner side of sliding groove 1. The upper and lower sides of support rod 2 and the top of support rod 3 are fixedly connected to blocking part 1. The bottom side of crossbeam 1 and the upper and lower sides of crossbeam 3 are fixedly connected to blocking part 2. Blocking part 1 is composed of multiple guard rod 1, and multiple guard rod 1 are symmetrically arranged on the upper and lower sides of support rod 2. Blocking part 2 is composed of multiple guard rod 2, and multiple blocking parts 1 and blocking parts 2 are staggered. Both of the column surfaces are provided with assembly mechanisms.

[0008] By adopting the above technical solution, the connecting part is used to cooperate with the sliding crossbeams on both sides to expand and contract, thereby enabling it to be assembled with columns at different intervals, thus improving the applicability of the protective structure.

[0009] As a further description of the above technical solution: the assembly mechanism includes multiple slot frames set on both sides of the column, and through holes are opened between the column and the multiple slot frames, and bolts are inserted into the inner side of the through holes. One end of the two crossbeams, crossbeam one and crossbeam three, is fixedly connected to a positioning seat, and the positioning seat is engaged with the slot frame. One side of the positioning seat is for the bolts to pass through through an opening.

[0010] By adopting the above technical solution: using multiple positioning seats to engage with the corresponding slot frame, and then combining the further positioning of the corresponding bolt two, the column and the connecting part, as well as the connected crossbeam one, crossbeam two and crossbeam three, can be quickly assembled and connected.

[0011] The technical effects and advantages of this utility model are as follows: 1. By setting up a telescopic mechanism, compared with the existing technology, the connecting part and the mutual sliding cooperation of the two side beams one, two and three can be adjusted by its own length to match different on-site road conditions and fit the different lengths of the spacing between the two columns, thereby improving the adaptability and flexibility of the protective structure. 2. By setting up an assembly mechanism, compared with the existing technology, multiple positioning seats and corresponding card slots are used to engage a damaged section of the guardrail, which can be disassembled separately without disturbing the intact structure on both sides. The damaged section can be replaced separately, improving construction efficiency and convenience. Attached Figure Description

Detailed Implementation

[0021] 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.

[0022] The embodiments disclosed in this application are as follows: Figures 1-5 The protective structure for the reconstruction of old asphalt pavement shown includes two columns 1, each with a base 2 fixedly connected to its bottom end, and a base column 14 fixedly connected to the bottom end of each base 2. A telescopic mechanism is provided between the two columns 1. The telescopic mechanism includes a connecting part between the columns 1. The connecting part includes two support rods 6 and two positioning frames 7, with the two positioning frames 7 symmetrically arranged on both sides of the two support rods 6. Support rods 8 and 9 are fixedly connected between the two positioning frames 7. Support rods 8 and 9 are sequentially arranged between and on the bottom sides of the two support rods 6. A crossbeam 3 and a crossbeam 5 are respectively sleeved at both ends of the two support rods 6 from top to bottom. The inner sides of both crossbeams 3 and 5 have grooves 12 for sliding the two support rods 6, and the inner sides of support rods 8 and 9 have grooves 2. Both ends of support rod 2 (8) and support rod 3 (9) are slidably connected to crossbeam 2 (4). Crossbeam 1 (3) and two crossbeam 3 (5) are symmetrically arranged at both ends of support rod 1 (6). Multiple crossbeam 2 (4) are symmetrically arranged at both ends of support rod 2 (8) and support rod 3 (9). One side of each crossbeam 3 (5) is threaded with bolt 1 (13), and the end of bolt 1 (13) extends to the inside of groove 1 (12). The upper and lower sides of support rod 2 (8) and the top of support rod 3 (9) are fixedly connected to a barrier part 1. The bottom side of crossbeam 1 (3) and the upper and lower sides of crossbeam 3 (5) are fixedly connected to a barrier part 2. The barrier part 1 consists of multiple protective rods 1 (10), which are symmetrically arranged on the upper and lower sides of support rod 2 (8). The barrier part 2 consists of multiple protective rods 1 (11), and the multiple barrier parts 1 and barrier parts 2 are staggered. Both columns 1 have assembly mechanisms on their surfaces. By utilizing the sliding cooperation between support rod 1 (6), support rod 2 (8), and support rod 3 (9) and the crossbeams 1 (3), 2 (4), and 3 (5) at both ends, the connecting part can be adapted to the expansion and contraction between the two columns 1 with different spacings. Combined with the interlacing of multiple barrier parts 1 and 2, effective barrier protection is achieved.

[0023] Reference Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, the assembly mechanism includes multiple slot frames 15 set on both sides of the column 1, and through holes are opened between the column 1 and the multiple slot frames 15. Bolts 16 are inserted into the inside of the through holes. One end of the two crossbeams 3, 4 and 5 are fixedly connected to positioning seats 17, and the positioning seats 17 are engaged with the slot frames 15. One side of the positioning seat 17 is for the bolts 16 to pass through. The positioning seats 17 at the ends of the crossbeams 3, 4 and 5 are engaged with the corresponding slot frames 15 on the side of the column 1, and the bolts 16 are used to position the connection points, so as to achieve stable assembly connection of the protective structure.

[0024] The working principle of this utility model is as follows: When modifying and protecting old asphalt pavement, the base 2 at the bottom of the two columns 1 is first placed on the pavement, and the base 2 is raised by the bottom column 14 on the bottom side of the two bases 2 to increase the contact surface between the base 2 and the pavement concrete. After the concrete at the installation point solidifies, the two columns 1 are kept fixed. First, move the two support rods 16 and the two positioning frames 7 between the two columns 1. Then, pull the multiple crossbeams 13, multiple crossbeams 24 and two crossbeams 35 on both sides of the two support rods 16, support rod 28 and support rod 39 toward the sides of the two columns 1. The sliding grooves 12 on the inner side of the two crossbeams 13 and crossbeams 35 assist them to move smoothly outward from both ends of the two support rods 16. At the same time, the sliding grooves 1 on the inner side of support rod 28 and support rod 39 can assist the two crossbeams 24 on both sides to be pulled to both sides, so that the positioning seats 17 at the ends of the crossbeams 13, the two crossbeams 24 and crossbeams 35 on both sides are moved above the multiple slot frames 15 on the sides of the two columns 1. Then, the positioning seats 17 at the ends of the two crossbeams 1-3, multiple crossbeams 2-4, and two crossbeams 3-5 are inserted into multiple slot frames 15, so that the openings on the side of the positioning seats 17 coincide with the through holes on the inside of the slot frames 15 and the columns 1. Then, multiple bolts 2-16 are inserted into the slot frames 15, columns 1, and positioning seats 17 in sequence, so that the two columns 1 and the connecting part, as well as the two crossbeams 1-3, multiple crossbeams 2-4, and two crossbeams 3-5 are assembled. Then, the bolts 1-13 on the side of the two crossbeams 3-5 are tightened, so that the ends of the two bolts 1-13 are pressed into the surface of the support rod 6 in the inner slide groove 12 for pressing and positioning, so that the connecting part and the crossbeams 1-3, crossbeams 2-4, and crossbeams 3-5 on both sides can extend and match the distance between the two columns 1. It is worth noting that by utilizing the interlocking of the first and second blocking parts on the upper and lower sides of the second support rod 8 and the top of the third support rod 9 with the second blocking parts on the bottom of the first crossbeam 3 and the upper and lower sides of the third crossbeam 5, the first and second guard rods can adaptively misalign themselves during the extension and retraction process, thus avoiding collisions and achieving the transformation and protection of old asphalt pavement.
