[0003] The existing temporary supports for bridge expansion joint construction usually involve first installing the support plates on the bridge, then fixing the joints of the left and right support plates with bolts and nuts, and then fixing the front and rear support plates with screws and nuts. Since the joints are fixed with bolts and nuts, the disassembly speed is slow and labor-intensive, and the screws and nuts between the front and rear support plates are exposed on the surface. When pouring concrete, it is easy for a portion of the concrete to fall on the screws and solidify, making it inconvenient to disassemble the screws.
[0004] Therefore, it is necessary to design a temporary support device for bridge deformation joint construction that can quickly disassemble the joints of the support plates to save manpower, and can shield and protect the screws to prevent concrete from solidifying on the screws, thereby improving the convenience of disassembling the device. Utility Model Content
[0005] In order to overcome the shortcomings of the existing temporary support for bridge deformation joint construction, the joints are fixed by bolts and nuts, the disassembly speed is slow, and it consumes manpower, and the screw rod and nut between the front and rear support plates are exposed on the surface, which easily causes a part of the concrete to fall on the screw rod and solidify when pouring concrete, making it inconvenient to disassemble the screw rod. The utility model provides a temporary support device for bridge deformation joint construction that can quickly disassemble the joints of the support plates, save manpower, and can shield and protect the screw rod to prevent concrete from solidifying on the screw rod, thereby improving the convenience of disassembling the device.
[0006] The technical solution of the utility model is: a temporary support device for the construction of bridge expansion joints, including a first support plate, a second support plate, a support frame, a screw, a nut, a steel plate and a connecting bolt. The first support plate is provided with two left and right plates, and the second support plate is provided with two left and right plates. The second support plates are both located at the rear side of the first support plate. The upper sides of the left and right parts of the first support plate and the upper sides of the left and right parts of the second support plate are both connected with support frames. The upper parts of the support frames on the rear side are rotatably connected with screws, and the screws are in contact with the support frames adjacent to the front side. The front parts of the screws are threadedly connected with nuts, and the nuts are in contact with the support frames adjacent to the front side. A plurality of steel plates are detachably connected between the first support plate on the right and the right side of the second support plate through a plurality of connecting bolts.
[0007] In one of the embodiments, a shielding cover is also included, and the shielding cover is rotatably connected to the rear support frame.
[0008] In one of the embodiments, a fixing plate is also included, and the lower side of the second supporting plate is connected to the fixing plate.
[0009] In one of the embodiments, a support rod is also included, and both the left and right parts of the first supporting plate are rotatably connected to the support rod.
[0010] In one embodiment, it also includes a connecting frame, a support block, a limiting frame, a guide rod and a telescopic spring. The upper and lower parts of the first supporting plate and the second supporting plate on the right are connected to the connecting frame, and the upper and lower parts of the first supporting plate and the second supporting plate on the left are connected to the support blocks. The connecting frames pass through adjacent support blocks, and the front and rear parts of the support blocks are slidably connected to the guide rods. A limiting frame is connected between two adjacent guide rods, and the limiting frames are in contact with adjacent connecting frames. Telescopic springs are connected between the lower sides of the front and rear parts of the limiting frames and the adjacent support blocks.
[0011] In one embodiment, a pull ring is provided on the upper side of the limiting frame.
[0012] Beneficial effects: The utility model rotates the shielding cover and then pours concrete. When the concrete solidifies, the limiting frame is moved upward, and the first support plate and the second support plate are taken out, so that the joints of the support plates can be quickly disassembled, saving manpower, and the screw can be shielded and protected to prevent concrete from solidifying on the screw, thereby improving the convenience of disassembling the device.
