Description

Technical Field

[0001] The utility model belongs to the technical field of road and bridge decks, and particularly relates to a reinforcement device for road and bridge deck joints. Background Art

[0002] The road and bridge deck refers to the deck slab of the bridge, which is regarded as an isotropic continuous slab supported on longitudinal ribs and diaphragms as an elastic body, and is a structure that directly bears the local wheel load. It is a part of the upper structure of the bridge and jointly bears the wheel load with the deck slab through longitudinal ribs and transverse ribs. At the head and tail splicing connection of the road and bridge deck, it is generally filled with a polymer filler. With the passage of vehicles, the connection of the bridge deck is prone to looseness and generate gaps, which need to be repaired regularly. After the repair, in order to further reinforce the protection of the gap filler at the connection of the bridge deck, a cover plate such as a steel plate is installed on the upper side of the gap at the connection node. At present, the connection method for the cover plate is generally direct welding or bolt connection by drilling holes in the road and bridge deck. This method of installing the cover plate is difficult to disassemble for secondary inspection and filling repair of the node gap during subsequent maintenance. With reasons such as water seepage, corrosion, and vehicle overload, the node gap will increase again, and a repair agent needs to be filled again. Forcibly disassembling it may even damage the road and bridge deck, resulting in an increase in the gap of the road and bridge deck. Content of the Utility Model

[0003] Aiming at the above problems, the purpose of the utility model is to provide a reinforcement device for road and bridge deck joints, which solves the problems that at the head and tail splicing connection of the road and bridge deck, it is generally filled with a polymer filler. With the passage of vehicles, the connection of the bridge deck is prone to looseness and generate gaps, which need to be repaired regularly. After the repair, in order to further reinforce the protection of the gap filler at the connection of the bridge deck, a cover plate such as a steel plate is installed on the upper side of the gap at the connection node. At present, the connection method for the cover plate is generally direct welding or bolt connection by drilling holes in the road and bridge deck. This method of installing the cover plate is difficult to disassemble for secondary inspection and filling repair of the node gap during subsequent maintenance. With reasons such as water seepage, corrosion, and vehicle overload, the node gap will increase again, and a repair agent needs to be filled again. Forcibly disassembling it may even damage the road and bridge deck, resulting in an increase in the gap of the road and bridge deck.

[0004] To achieve the above object, the technical solution adopted by the utility model is as follows: A road and bridge panel node reinforcement device includes a plurality of spliced road and bridge panels.

Connecting rods are respectively arranged on the upper sides of the clamping blocks. Installation plates are respectively arranged at the upper ends of the connecting rods. Mounting holes are symmetrically opened on the side faces of the installation plates.

At the upper ends of the connecting rods 7, mounting plates 10 are provided. Mounting holes are symmetrically opened on the side faces of the mounting plates 10. When subsequent maintenance is required, the mounting plate 10 can be directly removed from the beam frame, and then the long cover plate 2 can be quickly separated from the joint of the road and bridge panel 1, which is convenient for the subsequent repair work to be carried out quickly. After the repair is completed, the long cover plate 2 can be re-covered and fixed, without damaging the road and bridge panel 1, which provides great convenience for the subsequent repair and reinforcement of the road and bridge panel 1. The connecting rod 7 is a bidirectional threaded telescopic rod. The upper and lower output ends of the connecting rod 7 are respectively provided with a second connecting head 8 and a first connecting head 6. A first fixing block 5 is rotatably provided on the lower side of the first connecting head 6. The first fixing block 5 is fixedly connected to the clamping block 4.

The two sides of the upper surface of the unit cover plate 21 are inclined downward slopes, which reduces the impact force of the vehicle on the whole long cover plate 2 when passing through.

[0027] The working principle and usage process of the present utility model:

[0028] During use, after filling the gaps generated at the head and tail splicing joints of the road and bridge panel 1 with polymer filler and leveling the filler at the connection node gaps, place the long cover plate 2 on the upper side of the connection node gaps. The long cover plate 2 can cover the filler. The connecting rods 7 at both ends of the long cover plate 2 are fixed to the beam frames on both sides of the road and bridge by driving bolts through the mounting holes of the mounting plates 10. The connecting rods 7 will be fixed by the mounting plates 10 to keep the long cover plate 2 stable on the upper side of the joint. When subsequent maintenance is required, simply remove the mounting plates 10 from the beam frames to quickly remove the long cover plate 2 from the joint of the road and bridge panel 1, facilitating the rapid progress of subsequent repair work. After the repair is completed, re-cover the long cover plate 2 and fix it, without damaging the road and bridge panel 1, providing great convenience for the subsequent repair and reinforcement of the road and bridge panel 1.

A second fixing block 9 is rotatably arranged on the upper side of the second connector 8, and the second fixing block 9 is fixedly connected to the mounting plate 10. By turning the connecting rod 7, the upper and lower output ends of the connecting rod 7 extend to adjust the magnitude of the pressure of the connecting rod 7 on the clamping block 4, thereby facilitating the adjustment of the pressure of the long cover plate 2 on the surface of the road and bridge panel 1 after the long cover plate 2 is installed, ensuring that the long cover plate 2 can closely fit the upper side of the road and bridge panel 1. In addition, the long cover plate 2 is composed of multiple unit cover plates 21. Clamping grooves 3 are provided on the upper sides of both ends of the unit cover plates 21.

The bolts 11 all pass through the through holes and are threadedly connected to the connecting blocks 22, for freely assembling and lengthening the overall length of the long cover plate 2 to a certain extent according to needs. In addition, during use, corrosion-resistant rubber frames 12 are provided on the edges of the lower sides of the unit cover plates 21 to increase the sealing performance of the joint surface between the unit cover plates 21 and the road and bridge panel 1, reducing the penetration of water into the connection node gaps under the unit cover plates 21.
