Description

Technical Field

[0001] The utility model relates to the technical field of bridge construction, in particular to a bridge wet joint slab. Background Art

[0002] The bridge wet joint slab is a cover plate used in the construction process of the bridge wet joint. It is also called wet joint pedal, wet joint trench cover or expansion joint safety guard plate, etc. It is usually laid on the wet joint surface before pouring concrete in the wet joint. It has many functions and can ensure safety. It can effectively prevent construction workers from accidentally falling during construction, and tools or other objects from falling into the wet joints and affecting the traffic under the bridge. Construction workers can safely carry out construction operations on it, just like on flat ground, which not only ensures the safety of personnel but also speeds up construction.

[0003] During actual use, wet joint slabs of bridges are usually subjected to a lot of pressure. Most construction sites need to pass pedestrians and cargo trucks, which will pass through the wet joint slabs of bridges. The wet joint slabs of bridges are usually directly installed on both sides of the wet joints of bridges. The center of the bottom of the wet joint slabs of bridges is suspended. Since there is no support at the bottom, the middle section of the wet joint slabs of bridges will be subjected to great pressure when people and vehicles pass by. Over time, the center of the wet joint slabs of bridges will be deformed, and in severe cases, it will lead to fracture, causing safety accidents. Therefore, we propose a wet joint slab of bridges. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art. In actual use, the wet joint cladding of the bridge is usually subjected to more pressure. Since most construction sites need to pass pedestrians and trucks carrying goods, these will pass through the wet joint cladding of the bridge, and the wet joint cladding of the bridge is usually directly installed on both sides of the wet joint of the bridge. The center of the bottom of the wet joint cladding of the bridge is in a suspended state. Since there is no support at the bottom, the middle section of the wet joint cladding of the bridge will be subjected to great pressure when people and vehicles pass by. If things go on like this for a long time, the center of the wet joint cladding of the bridge will be deformed, and in severe cases, it will lead to fracture, causing a safety accident.

[0007] Preferably, the connecting and fixing seat can be slidably connected between a sliding block and a sliding groove of the supporting seat, and the connecting and fixing seat connects the two supporting seats.

[0008] Preferably, the two connecting blocks can slide in the two connecting grooves at the bottom of the butt plate body, thereby achieving rapid installation and disassembly.

[0009] Preferably, the bottom of the buffer support structure is fixed to the connecting and fixing seat, and the top of the buffer support structure is fixed to the butt plate body.

[0010] Preferably, the buffer support structure comprises an outer shell, an outer oil cavity is provided inside the outer shell, an inner shell is provided inside the outer oil cavity, and a through hole is provided at the bottom of the inner shell.

[0011] Preferably, a pressure rod is further provided on the top of the shell, a piston is connected to the bottom of the pressure rod, a plurality of damping holes are provided on the piston, and a buffer spring is provided on the outside of the shell.

[0025] Example 1

[0026] like Figure 1-5 As shown, the utility model provides a technical solution: a bridge wet joint spanning plate, comprising a spanning plate body 1, connecting grooves 2 are opened on both sides of the bottom of the spanning plate body 1, connecting blocks 3 are connected to the inside of the two connecting grooves 2, the bottoms of the two connecting blocks 3 are fixedly connected to support seats 4, sliding grooves 5 are opened on the inner side walls of the two support seats 4, sliding blocks 6 are connected to the inside of the two sliding grooves 5, a connecting fixed seat 7 is provided between the two sliding blocks 6, and a plurality of buffer support structures 8 are fixedly connected to the top of the connecting fixed seat 7. The device can realize auxiliary support and buffering of the spanning plate body 1 by the buffer support structure 8 on the basis of supporting the spanning plate body 1, thereby realizing protection of the spanning plate body 1, so that the spanning plate body 1 will not bear all the pressure alone during the downward pressing process, thereby prolonging the service life and improving the stability when passing by people and vehicles, and the various components of the device can be quickly disassembled and installed, thereby being more convenient during transportation.

[0027] Example 2

[0028] like Figure 1-5 As shown, the utility model provides a technical solution: the connecting fixed seat 7 can be slidably connected between the sliding groove 5 of the support seat 4 through the sliding block 6, the connecting fixed seat 7 connects the two support seats 4, and the strap body 1 is pulled outward to disengage the connecting groove 2 of the strap body 1 from the connecting block 3 of the support seat 4, so that the strap body 1 can be completely separated from the support seat 4, completing the disassembly of the strap body 1.

[0029] The two connecting blocks 3 can slide in the two connecting grooves 2 at the bottom of the strap body 1, thereby realizing quick installation and disassembly, and the sliding block 6 of the connecting fixing seat 7 can slide in the sliding groove 5 of the support seat 4, so that the connecting fixing seat 7 can be separated from the two support seats 4. After the connecting fixing seat 7 is separated, the two support seats 4 lose the connection support of the connecting fixing seat 7, and then the two support seats 4 can also be taken away separately, thereby realizing quick disassembly and installation of the device.

[0030] The bottom of the buffer support structure 8 is fixed to the connection fixing seat 7 , and the top of the buffer support structure 8 is fixed to the buttress body 1 .

[0031] The buffer support structure 8 comprises an outer shell 81 , an outer oil cavity 82 is provided inside the outer shell 81 , an inner shell 83 is provided inside the outer oil cavity 82 , and a through hole 84 is provided at the bottom of the inner shell 83 .

[0032] A pressure rod 85 is also provided on the top of the housing 81 . A piston 86 is connected to the bottom of the pressure rod 85 . A plurality of damping holes 87 are formed on the piston 86 . A buffer spring 88 is provided on the outside of the housing 81 .

[0033] The pressure rod 85 drives the piston 86 to move inside the inner shell 83. The bottom and top of the buffer spring 88 are respectively fixed between the connecting and fixing seat 7 and the board body 1. When a person or a bucket car passes over the board body 1, the middle part of the board body 1 will be squeezed downward and squeezed to the buffer support structure 8. The buffer support structure 8 is fixedly installed at the connecting and fixing seat 7, and the connecting and fixing seat 7 is fixed on the two support seats 4. Therefore, when the bucket car is pushed over, the above structure will share the pressure, making it more stable when passing through, and at the same time, the board body 1 can be protected. In addition, because the buffer support structure 8 is set When the buffer support structure 8 is subjected to pressure, it will reduce shock through the buffer spring 88. At the same time, the pressure rod 85 will be subjected to force and drive the piston 86 to move downward. The piston 86 is provided with a plurality of damping holes 87, so the buffer oil will move upward through the plurality of damping holes 87, thereby achieving preliminary shock absorption and pressure absorption. The outer oil chamber 82 and the inner oil chamber inside the inner shell 83 are both filled with buffer oil, and in the process of shock absorption, the buffer oil inside the inner oil chamber will move to the outer oil chamber 82 through the through hole 84, thereby absorbing the second part and slowing down the compression and reset rate of the buffer spring 88.

[0034] The working process of the utility model is as follows: when using a bridge wet joint spanning board, first, during installation and disassembly, it is necessary to first pull the spanning board body 1 outward to disengage the connecting groove 2 of the spanning board body 1 from the connecting block 3 of the support seat 4, so that the spanning board body 1 can be completely separated from the support seat 4, and the disassembly of the spanning board body 1 is completed. It should be noted that when the device is installed on the wet joint of the bridge, the two ends of the spanning board body 1 will be blocked by the bridge or the mounting fixtures, and thus during actual use, the spanning board body 1 will not be separated from the connecting block 3, and can only be separated when being taken down for disassembly or installation.

[0035] Then it is necessary to separate the two support seats 4 and the connecting and fixing seats 7. Since the strap body 1 has been detached, it is only necessary to pull the connecting and fixing seats 7. The sliding block 6 of the connecting and fixing seats 7 will slide in the sliding groove 5 of the support seat 4, so that the connecting and fixing seats 7 can be detached from the two support seats 4. After the connecting and fixing seats 7 are detached, the two support seats 4 lose the connection support of the connecting and fixing seats 7, and the two support seats 4 can be taken away separately, thereby realizing the rapid disassembly and installation of the device. During transportation, the disassembly method of this scheme is adopted, and the separate components are also more convenient to transport.

[0036] When a person or a bucket truck passes over the ramp body 1, the middle part of the ramp body 1 will be squeezed downward and squeezed to the buffer support structure 8, and the buffer support structure 8 is fixedly installed at the connecting fixing seat 7, and the connecting fixing seat 7 is fixed on the two support seats 4. Therefore, when the bucket truck is pushed over, the above structure will share the pressure, making it more stable when passing, and at the same time, the ramp body 1 can be protected. In addition, because the buffer support structure 8 is provided, the buffer support structure 8 will be shock-absorbing through the buffer spring 88 when it is under pressure. At the same time, the pressure rod 85 will be stressed and drive the piston 86 to move downward, and a number of damping holes 87 are opened on the piston 86, so the buffer oil will move upward through the damping holes 87, thereby achieving preliminary shock absorption and pressure absorption. The outer oil chamber 82 and the inner oil chamber inside the inner shell 83 are filled with buffer oil, and in the process of shock absorption, the buffer oil inside the inner oil chamber will move to the outer oil chamber 82 through the through hole 84, thereby absorbing the second part and slowing down the compression and reset rate of the buffer spring 88.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
