[0003] However, in actual applications, during most existing road and bridge construction operations, multiple baffles are usually spliced end to end by riveting to separate the construction area and the traffic area to improve safety. However, the riveted connection method is not only cumbersome during installation, but also causes permanent damage to the surface of the baffle, resulting in a situation where it cannot be reused later, which is not conducive to popularization and use.

[0004] Therefore, technical personnel in this field have provided a safety support and protection frame for road and bridge construction to solve the problems raised in the above background art. Utility Model Content

[0010] At the edges of the two protective plates, two threaded sleeves are fixedly connected. The installation positions of two of the four threaded sleeves are lower than those of the other two threaded sleeves. The four threaded sleeves are divided into two groups, and threaded rods are threadedly connected to the inner walls of each group of threaded sleeves.

[0011] Preferably, fluorescent paint is applied to the surfaces of the two protective plates.

[0012] The top end of the screw rod is fixedly connected with a hexagonal drive block.

[0013] Preferably, fluorescent paint is applied to the surfaces of the two protective plates.

[0014] In summary, the present application includes the following beneficial technical effects:

[0015] 1. By setting the protective plates, the base is fixed to the ground of the placement area using fixing bolts. At this time, the two protective plates are in an upright state, so that the construction area and the passage area can be effectively separated. In this way, an appropriate amount of protective plates can be selected according to the length of the construction area and arranged in a row to form a safety protection effect.

[0021] The following will be combined with the attached Figures 1 - 3The technical solution of the present utility model is clearly and completely described. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0022] An embodiment of the present application discloses a safety support and protection frame for road and bridge construction. Referring to Figures 1 - 3 , it includes a base 1. Four through holes are opened on the top side of the base 1. Fixed bolts are installed on the inner walls of the four through holes. A support rod 2 is fixedly connected to the top side of the base 1. A support sleeve 3 is slidably sleeved on the outer side of the support rod 2. Protective plates 4 are fixedly connected to both the left and right sides of the support sleeve 3; by setting the protective plates 4, the base 1 is fixed to the ground in the placement area by the fixed bolts. At this time, the two protective plates 4 are in an upright state, so that the construction area and the passing area can be effectively separated. In this way, an appropriate amount of protective plates 4 can be selected according to the length of the construction area and arranged in a row to form a safety protection effect. Compared with the method of riveting multiple baffles together, the purpose of repeated use can be effectively achieved, the use cost is reduced, and it is beneficial to promote the use.

[0023] In the present application, a screw rod 5 is rotatably connected to the center of the top side of the support sleeve 3. A screw groove is opened at the center of the support rod 2. The screw rod 5 is in screw transmission connection with the inner wall of the screw groove; by setting the screw rod 5 and the screw groove, when the screw rod 5 rotates, it will be gradually lifted upward under the limitation of the screw groove. The movement of the screw rod 5 drives the support sleeve 3 to move upward, and the support sleeve 3 drives the protective plate 4 to move upward, so that when the protective plate 4 is in a low-lying area, it can be lifted upward to avoid interference with the installation, thereby improving the convenience of use.

[0024] In the present application, two threaded sleeves 6 are fixedly connected to the edges of the two protective plates 4. The installation positions of two of the four threaded sleeves 6 are lower than the installation positions of the other two threaded sleeves 6. The four threaded sleeves 6 are divided into two groups, and the inner walls of each group of threaded sleeves 6 are threadedly connected with threaded rods 7; by setting the threaded sleeves 6 and the threaded rods 7, the threaded sleeves 6 and the threaded rods 7 can cooperate during installation to install multiple protective plates 4 in a head-to-tail connection manner, improving the convenience of use. When disassembly is required, the threaded rod 7 can be directly screwed out.

[0025] In the present application, a hexagonal drive block 8 is fixedly connected to the top end of the screw rod 5; by setting the hexagonal drive block 8, when the screw rod 5 is turned, the hexagonal drive block 8 can facilitate people to use tools to turn the screw rod 5, thereby achieving the purpose of saving effort.

[0026] In this application, fluorescent coatings are applied to the surfaces of both protective plates 4. By setting the surfaces of both protective plates 4 to be coated with fluorescent coatings, a certain warning effect can be achieved in a dim environment, avoiding the occurrence of danger.

[0027] All standard parts used in this utility model can be purchased from the market. Special-shaped parts can be customized according to the descriptions in the specification and the drawings. The specific connection methods of each part all adopt conventional means such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts, and equipment all adopt conventional models in the prior art. In addition, the circuit connection adopts the conventional connection method in the prior art, which will not be elaborated here.

[0028] The implementation principle of a road and bridge construction safety support and protection frame in an embodiment of this application is as follows: When in use, the base 1 is fixed to the ground in the placement area by fixing bolts. At this time, the two protective plates 4 are in an upright state, so that the construction area and the passage area can be effectively separated. By using this method, an appropriate amount of protective plates 4 can be selected according to the length of the construction area and arranged in a row to form a safety protection effect. Compared with the method of riveting multiple baffles together, the purpose of repeated use can be effectively achieved, reducing the use cost and being conducive to popularization and use. When the screw rod 5 rotates, it will gradually move upward under the limitation of the spiral groove. The movement of the screw rod 5 drives the support sleeve 3 to move upward, and the support sleeve 3 drives the protective plate 4 to move upward, so that when the protective plate 4 is in a low-lying area, it can be lifted upward to avoid interference with the installation, thereby improving the convenience of use. During the installation process, the threaded sleeve 6 and the threaded rod 7 cooperate to enable the multiple protective plates 4 to be installed in a head-to-tail connection manner, improving the convenience of use. When disassembly is required, the threaded rod 7 can be directly screwed out. When the screw rod 5 is turned, the hexagonal drive block 8 can facilitate people to use tools to turn the screw rod 5, thereby achieving the purpose of saving effort. Fluorescent coatings are applied to the surfaces of both protective plates 4, so that a certain warning effect can be achieved in a dim environment, avoiding the occurrence of danger.
