Description

Technical Field

[0001] The utility model belongs to the technical field of protective structures, in particular to a road surface protective structure for highway and bridge construction. Background Art

[0002] The construction period of road and bridge pavement is generally long, sometimes even more than half a year, or the pavement needs to be repaired after being used for a long time. Generally, pedestrians or vehicles are not allowed to enter the pavement before the construction is completely completed. Therefore, warning signs, warning tapes, piles of soil and stones are used to warn pedestrians and vehicles to prevent pedestrians and vehicles from mistakenly entering the pavement to be improved, thereby improving the protection of the pavement.

[0003] In a Chinese patent with announcement number CN219118928U, a bridge construction pavement protection structure is mentioned. The utility model selects a suitable number of protection components according to the construction conditions of the pavement, and installs the first column and the second column. The shielding distance of the protection sheet should exceed the length of the construction pavement. After the protection sheet is installed, the upper extension plate and the lower extension plate are installed. If it is manually felt that the coverage of the protection sheet is not enough, the upper extension plate and the lower extension plate can be extended up and down to increase the area of ​​the protection sheet. After the construction is completed, the screw is reversed and the motor is started to retract the protection sheet. When the protection sheet is extended, the motor can also be used, but the extension of the protection sheet needs to be manually assisted to prevent the protection sheet from being stuck in the second column.

[0004] However, when the device is in use, a large number of bolts are required to sequentially install the first column, the second column, the upper extension plate and the lower extension plate of the protective sheet, which is inconvenient to install and reduces the installation efficiency of the protective structure. Secondly, the protective sheet is a hard plate, and it is difficult to adjust the angle. It is not suitable for curved roads, which reduces the applicability of the protective structure.

[0025] Embodiment 1: The utility model provides a road surface protection structure for highway and bridge construction, including a main body mechanism 100 and a fixing mechanism 200. The main body mechanism 100 includes a mesh frame 101, and a plurality of crisscrossing protection ropes 102 are fixedly installed inside the mesh frame 101.

[0026] There are two fixing mechanisms 200, which are respectively installed at the rear end of the screen frame 101 and the front end of the storage component. The fixing mechanism 200 includes two supporting columns 201 installed relatively to each other. The lower ends of the two supporting columns 201 are fixedly installed with support plates 202, and the upper ends of the two support plates 202 are opened with a plurality of installation holes.

[0027] The rear end of the screen frame 101 and the front end of the support plate 103 are both fixedly mounted with mounting plates 203 , and the two mounting plates 203 are respectively connected to the two support columns 201 via a plurality of connecting bolts 204 .

[0028] As can be seen from the above, during construction, the road surface is protected. In order to prevent pedestrians and vehicles from stepping onto the unfinished road surface, the road surface protection device is placed at the end of the road surface that needs to be protected, and the distance between the two support columns 201 is adjusted through the main mechanism 100 according to the width of the road surface. After adjusting to a suitable distance, the support plate 202 and the mounting holes provided therein are used to fix the support plate 202, thereby fixing the support column 201, that is, fixing the road surface protection structure, and protecting the road surface. The main mechanism 100 can be easily disassembled through the mounting plate 203 and the connecting bolt 204, which is convenient for storage, transportation, repair and replacement.

[0029] Embodiment 2: This is the second embodiment of the utility model, including a main body structure 100, the main body structure 100 includes a mesh frame 101, a plurality of criss-crossing protective ropes 102 are fixedly installed inside the mesh frame 101, and a storage component is fixedly installed at the front end of the protective rope 102, which is used to store the mesh frame 101 and the protective rope 102.

[0030] The net frame 101 and the plurality of protection ropes 102 are both made of soft materials, and the plurality of protection ropes 102 are elastic.

[0031] The storage assembly includes two relatively mounted support plates 103, with a rotating shaft 104 rotatably passing through the support plates 103, a storage tube 105 fixedly mounted on the outer surface of the rotating shaft 104, the outer surface of the storage tube 105 is fixedly connected to the front end of the net frame 101, and a handle 106 is fixedly mounted on the lower end of the rotating shaft 104.

[0032] A guide groove 107 is fixedly installed between the two support plates 103 , and the screen frame 101 and a plurality of protection ropes 102 pass through the guide groove 107 . Scrapers 108 are fixedly installed on both sides of the guide groove 107 , and the two scrapers 108 are in contact with the screen frame 101 and the protection ropes 102 .

[0033] As can be seen from the above, when in use, firstly, according to the width of the road surface, the handle 106 is rotated to make the rotating shaft 104 rotate forward, and the mesh frame 101 and the protective rope 102 wound on the storage tube 105 are loosened, so that the width of the loosened mesh frame 101 and the protective rope 102 is close to the width of the road surface, and the support column 201 is fixed on both sides of the road surface, so that the mesh frame 101 and the protective rope 102 are in a taut state, pedestrians and vehicles are intercepted, and pedestrians and vehicles are prevented from mistakenly entering the unused road surface and causing damage to the construction road surface, thereby protecting the road surface, and the mesh frames 101 and the protective rope 102 of different widths can be released according to the width of the road surface. Then it can be applied to roads of different widths. The mesh frame 101 and the protective rope 102 are flexible, so they can be bent at will, which is convenient for installation and adaptable to different installation environments, thereby improving the applicability of the device. Secondly, after use, by reversing the handle 106, the mesh frame 101 and the protective rope 102 are wound around the outer surface of the storage tube 105, thereby reducing the volume of the protective structure and facilitating storage and transportation. Finally, the protective rope 102 has a certain elasticity. When pedestrians or vehicles accidentally collide with it, the elastic properties of the protective rope 102 are used to deform it to prevent the pedestrians or vehicles from colliding with the hard board, thereby further reducing the damage to the pedestrians or vehicles.

[0034] After use, when the screen frame 101 and the protection rope 102 are stored, they pass through the guide groove 107 and the scraper 108, so that the screen frame 101 and the protection rope 102 can be cleaned of impurities such as dust and dirt.
