Description

Technical Field

[0001] The utility model relates to the technical field of prefabricated concrete parts, in particular to a prefabricated bridge slab. Background Art

[0002] Prefabricated bridge slabs play an increasingly important role in production and construction. Prefabricated bridge slabs are also commonly called prefabricated hollow slabs, prestressed bridge slabs, hollow slabs, etc. They are divided into hollow slab beams, box beams, T-beams, etc. according to the cross-sectional form. They are the upper components of bridges made of reinforced concrete. In the construction of bridges, sometimes the bridge slabs are prefabricated with reinforced concrete first, and then the piers and abutments are constructed on site, and then the bridge slabs are fixed to the piers to form a bridge.

[0003] However, the bridge deck is only suitable for some smaller bridges and rivers with slow water flow. Some existing bridge decks are installed on the top of the piers in sequence with bolts when in use. There is no connection effect between each bridge deck. After long-term use, the bridge deck is prone to deviation, which leads to cracks at the connection of the bridge deck, which not only affects the normal use, but also affects the stability of the bridge.

[0004] At the same time, when the existing bridge deck is in use, water will flow over the bridge during the rainy season, causing the water flow to have a greater impact on the bridge deck, and the bridge deck is prone to position displacement, which affects the service life of the bridge and reduces the safety of the bridge. Utility Model Content

[0005] The purpose of the utility model is to provide a prefabricated bridge deck to solve the problems raised in the above background technology.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-4As shown, a prefabricated bridge deck comprises a bridge deck body 1. The bridge deck body 1 is composed of a concrete and steel bar structure, so that the bridge deck body 1 has a high strength, thereby improving the service life of the bridge deck. Both sides of the bottom of the bridge deck body 1 are fixedly connected with reinforcement blocks 11. The reinforcement blocks 11 can increase the strength of the bridge deck body 1, thereby making the strength of the bridge deck body 1 higher and preventing the bridge deck body 1 from being easily broken. A mounting groove 2 is provided on one side of the bridge deck body 1, and moving mechanisms 3 are installed on both sides of the inner cavity of the mounting groove 2. The inner wall of the mounting groove 2 is slidably connected with a moving block 4, which can be driven to move under the action of the moving mechanism 3. A connecting groove 5 is provided on the other side of the bridge deck body 1, and the inner wall of the connecting groove 5 is slidably connected to the surface of the moving block 4. Under this action, when the bridge board is spliced ​​and used, the moving block 4 can be embedded in the inside of another bridge board, so as to improve the connection effect of the bridge board. The bottom and top of the inner cavity of the installation groove 2 and the connecting groove 5 are fixedly connected with guide blocks 12, and the bottom and top of the moving block 4 are provided with guide grooves 13. The surface of the guide block 12 is slidably connected with the inner wall of the guide groove 13. Under this action, the moving block 4 can be guided when it moves, so that the moving block 4 can be more stable when moving, and the contact area of ​​the moving block 4 entering the connecting groove 5 can be increased, thereby improving the strength of the bridge board after splicing and use. The width of the connecting groove 5 is half the width of the moving block 4. Under this action, one side of the moving block 4 can remain in the inside of the installation groove 2, and the other side can be embedded in another The inside of the connecting groove 5 of the bridge plate makes the force of the moving block 4 more stable, avoiding the situation that the moving block 4 is unevenly stressed and affects the connection effect. Positioning grooves 6 are opened at two places on both sides of the bridge plate body 1. The inner wall of the positioning groove 6 on one side is slidably connected with a positioning block 7, and one side of the positioning block 7 is fixedly connected with a diverter block 8. The diverter block 8 is designed as a wedge-shaped structure. The top of the diverter block 8 is on the same horizontal line as the top of the bridge plate body 1, and the bottom of the diverter block 8 is on the same horizontal line as the bottom of the reinforcement block 11. Under the action of the diverter block 8, when the water flow submerges the bridge plate, the water can be diverted under the action of the shape, thereby reducing the resistance between the bridge plate body 1 and the water, avoiding the bridge plate from being impacted to other positions under the action of the water flow. The positioning block 7 and the fixed The cross-sectional shape of the positioning groove 6 is a T-shaped structural design. One side of the diverter block 8 is slidably connected to the surface of the bridge plate body 1. Under the action, the positioning block 7 is embedded in the interior of the positioning groove 6 and will not be easily moved out from the interior thereof, thereby improving the stability of the positioning block 7 and preventing the positioning block 7 from moving out of the interior of the positioning groove 6 and affecting the diversion of water by the diverter block 8. Nuts 9 are embedded at two locations on both sides of the surface of the bridge plate body 1, and a bolt 10 is provided on one side of the diverter block 8. The other end of the bolt 10 penetrates to the other side of the diverter block 8 and is rotatably connected to the inner wall of the penetration point. The surface of the bolt 10 is threadedly connected to the inner wall of the nut 9. Under this action, the diverter block 8 can be easily disassembled, so that the staff can adjust the position of the diverter block 8 according to the actual installation situation.

[0023] The moving mechanism 3 includes a positioning rod 31 arranged in the inner cavity of the mounting groove 2, one end of the positioning rod 31 passes through the outer side of the bridge plate body 1 and is rotatably connected to the inner wall of the penetration point, and a bevel gear set 32 ​​is installed at the bottom of the positioning rod 31, and the bevel gear set 32 ​​is composed of two bevel gears of the same size that mesh with each other, and a threaded rod 33 is installed on one side of the bevel gear set 32, and a sleeve 34 is embedded on one side of the moving block 4, and the surface of the threaded rod 33 is threadedly connected to the inner wall of the sleeve 34. After the staff rotates the positioning rod 31, the threaded rod 33 can be driven by the bevel gear set 32 ​​to make the sleeve 34 adjust the position of the moving block 4, so as to facilitate the splicing of the two bridge plates, and one side of the surface of the threaded rod 33 is rotatably connected to the support plate 14, and the bottom of the support plate 14 is fixedly connected to the inner wall of the mounting groove 2. Under this action, the threaded rod 33 can be supported, so that it can be more stable when rotating.

[0024] It is worth noting that the technical features such as the bridge deck body 1 proposed in this technical solution should be regarded as prior art. The specific structure, working principle, and possible control method and spatial layout method of these technical features can be selected according to conventional methods in the field, and this technical solution will not be further elaborated.

[0025] Working principle: First, when the bridge board needs to be installed, the bridge boards are placed in sequence, and then the staff uses an auxiliary tool to rotate the positioning rod 31 to drive the bevel gear set 32 ​​to rotate. Under the action of the bevel gear set 32, the threaded rod 33 can move the moving block 4 through the cooperation of the sleeve 34, so that the moving block 4 is embedded in the connecting groove 5, so as to connect the two bridge boards, and then all the bridge boards are connected in this way. When the diverter block 8 does not correspond to the direction of the water flow, the staff uses an auxiliary tool to rotate the bolt 10 to release the limit on the diverter block 8, and then use the diverter block 8 to move the positioning block 7 out of the inside of the positioning groove 6 and place it in the inside of the positioning groove 6 on the other side, and then use the bolt 10 to fix the diverter block 8 so that the position of the diverter block 8 corresponds to the direction of the water flow.
