Description

Technical Field

[0001] This utility model relates to the field of support device technology, and in particular to a support device for spraying and curing concrete guardrails for bridges. Background Technology

[0002] Currently, reinforced concrete guardrails are the primary type used for bridge safety in China. The construction quality of these concrete crash barriers directly impacts bridge safety during operation. A crucial step in ensuring the quality of crash barrier construction is concrete curing. Inadequate curing can easily lead to concrete cracking, requiring secondary repairs, increasing workload, and compromising the quality of the crash barrier. Currently, the curing of concrete crash barriers in Chinese bridges is mostly done manually. Traditional manual curing requires regular, scheduled work and cannot provide 24-hour continuous maintenance, resulting in significant labor costs. Therefore, we propose a spray curing support device for bridge concrete crash barriers. Summary of the Invention

[0003] The purpose of this utility model is to address the problem that traditional manual maintenance in the background technology requires regular manual maintenance, which cannot achieve uninterrupted maintenance for hours and involves a large amount of manual labor.

[0028] Example

[0029] like Figures 1 to 4 As shown, the present invention proposes a bridge concrete crash barrier spray curing support device, including a concrete crash barrier 1 and a water tank 4. The construction length of the crash barrier 1 is generally 10m. The main water supply pipe 2, spray branch pipes 7 and omnidirectional nozzles 10 are installed on the bridge deck in advance. Each section is 2-3m long. When carrying out the next concrete curing, this device can be directly transferred to the corresponding position without repeated installation. The structure is simple and the operation is convenient. It also includes a main water supply pipe 2. One side of the main water supply pipe 2 is connected to a connecting pipe 3 connected to the water tank 4. A water pump 5 is installed on the connecting pipe 3. When the water pump 5 is started, the water in the water tank 4 enters the main water supply pipe 2 through the connecting pipe 3. Multiple sets of spray branch pipes 7 are fixedly connected to the main water supply pipe 2.

[0030] Each set of spray branch pipes 7 in the connecting pipe 3 includes an inner spray branch pipe 71, an outer spray branch pipe 72 and a wall-top spray branch pipe 73. On the side of the inner spray branch pipe 71, the outer spray branch pipe 72 and the wall-top spray branch pipe 73 away from the main water supply pipe 2, an omnidirectional nozzle 10 is fixedly connected. The water in the main water supply pipe 2 is sprayed out through the omnidirectional nozzle 10 fixedly installed at one end of the inner spray branch pipe 71, the outer spray branch pipe 72 and the wall-top spray branch pipe 73, so as to carry out all-round automatic spraying maintenance of the guardrail 1, reduce manual input, better protect the concrete curing quality of the bridge anti-collision wall, and effectively avoid the cracking of the concrete surface.

[0031] In addition, the spacing between the inner spray branch pipe 71, the outer spray branch pipe 72 and the wall top spray branch pipe 73 is preferably 10cm, the spacing between each group of spray branch pipes 7 is preferably 50cm, the main water supply pipe 2 is preferably a PVC pipe with a diameter of 48mm, and the spray branch pipe 7 is preferably a plastic hose with a diameter of 15mm.

[0032] In this embodiment, the top of the guardrail 1 is provided with several sets of bracket assemblies for supporting the main water supply pipe 2. The bracket assembly includes a snap-on bracket 6 and an mounting piece 12 fixedly installed on the top of the guardrail 1. The snap-on bracket 6 includes a semi-circular support piece 61 for placing the main water supply pipe 2, a connecting rod 62 fixedly installed at the bottom of the semi-circular support piece 61, and a connecting piece 63 movably installed on the top of the guardrail 1. The connecting piece 63 is fixedly installed at the bottom of the connecting rod 62.

[0033] The buckle bracket 6 is welded from waste round steel or threaded steel bars at the construction site. The buckle bracket 6 has a reinforcing frame 11 slidably installed on both sides. The mounting part 12 is provided with a locking block 13 for fixing the reinforcing frame 11. The connecting rod 62 has a sliding groove 64 fixedly installed on both sides. The sliding slider is slidably installed in the sliding groove 64 and fixedly connected to the reinforcing frame 11. The top of the mounting part 12 has a groove 121 for the reinforcing frame 11 to be inserted. The reinforcing frame 11 is slidable so that the bottom end of the reinforcing frame 11 is inserted into the groove 121 at the top of the mounting part 12.

[0034] In addition, the bottom of the reinforcing frame 11 has slots 111 on both sides for inserting the locking blocks 13. The bottom of each locking block 13 is fixedly installed with a sliding member 14. The sides of the groove 121 have a first rectangular groove 122 and a second rectangular groove 123 for the locking blocks 13 and sliding members 14 to pass through. A guide rod 9 is fixedly installed between the second rectangular grooves 123. The sliding member 14 is slidably sleeved on the guide rod 9. A spring 8 is fixedly connected between the sliding members 14. The spring 8 is sleeved on the outside of the guide rod 9. During the insertion of the reinforcing frame 11, the bottom of the reinforcing frame 11 presses against the locking block 13. Under the action of the spring 8, the locking block 13 enters the slot 111, thereby further fixing the buckle bracket 6, improving the stability of the buckle bracket 6 in supporting the main water supply pipe 2, enhancing the overall wind resistance of the bracket device, preventing the device from shaking or shifting in strong winds, and ensuring the normal operation of the spray maintenance.

[0035] The working principle of this embodiment is as follows: During the working process, the mounting component 12 is fixedly installed on the top of the guardrail 1 with bolts, and then the buckle bracket 6 is snapped onto the top of the guardrail 1. At the same time, the reinforcing frame 11 located on both sides of the buckle bracket 6 is slid, so that the bottom end of the reinforcing frame 11 is inserted into the groove 121 on the top of the mounting component 12. During the insertion of the reinforcing frame 11, the bottom end of the reinforcing frame 11 presses against the locking block 13 slidably installed in the first rectangular groove 122. Under the action of the spring 8, the locking block 13 enters into the locking groove 111 opened on both sides of the reinforcing frame 11, thereby further fixing the buckle bracket 6, improving the stability of the buckle bracket 6 in supporting the main water supply pipe 2, enhancing the overall wind resistance of the support device, preventing the device from shaking or shifting in strong winds, and ensuring that the spray maintenance is carried out normally.

[0036] Start the water pump 5 so that the water in the water tank 4 enters the main water supply pipe 2 through the connecting pipe 3, and then sprays out through the omnidirectional nozzles 10 fixedly installed at one end of the inner spray branch pipe 71, the outer spray branch pipe 72, and the top spray branch pipe 73 of the wall, so as to carry out comprehensive spraying and curing of the guardrail 1, which can better protect the curing quality of the bridge crash barrier concrete and effectively avoid the cracking of the concrete surface.

[0037] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
