Description

Technical Field

[0001] The utility model relates to the technical field of ocean engineering, and more specifically to a pier multi-span concrete beam integral heightening pier cushion block. Background Art

[0002] Basically, the design wave elements of the pier elevation in China are all once in 50 years. However, in recent years, extreme weather has occurred frequently in China. The extreme weather has caused the tide level to far exceed the design extreme high water level of the pier. There have been many cases where the pier has been damaged by extreme weather or the pier surface layer has been flooded by the tide. Many port piers, due to being in disrepair for years and being affected by extreme weather, have caused the pier to shift or have insufficient elevation, seriously affecting the safe operation of the pier.

[0003] In order to ensure the safe operation of the pier, it is necessary to repair the pier. During the repair process, it is necessary to lift the concrete beam, and during the lifting process, it is necessary to support the concrete beam. The existing pier cushion blocks mostly use steel plates, but there are many problems with them and they need to be improved. Content of the Utility Model

[0004] The utility model overcomes the deficiencies in the prior art and provides a pier multi-span concrete beam integral heightening pier cushion block.

[0005] The purpose of the utility model is realized by the following technical solutions.

[0006] A pier multi-span concrete beam integral heightening pier cushion block includes: a top plate, a bottom plate and a support plate assembly. The top plate and the bottom plate are rectangular plates with the same structure. A plurality of connection and fixing holes are provided at the same positions on the top plate and the bottom plate. The top plate and the bottom plate are fixedly connected through the support plate assembly, and the space between the top plate and the bottom plate is communicated with the outside.

[0007] The support plate assembly includes a central support plate and two side support plates. The central support plate is a cross-shaped support plate structure and is respectively connected to the transverse center line and the longitudinal center line of the top plate and the bottom plate. The two side support plates are correspondingly arranged at the positions of the short sides of the top plate and the bottom plate.

[0008] The number of the connection and fixing holes is 4, and the connection and fixing holes are symmetrically arranged in pairs.

[0009] Each cushion block is connected by arranging fixing pieces on the connection and fixing holes of the adjacent top plate and bottom plate.

[0010] The distance between the top surface of the top plate and the bottom surface of the bottom plate is 10 - 20 cm.

[0011] The top plate, the bottom plate and the support plate assembly are made of steel material.

[0012] The beneficial effects of the present utility model are as follows: The pier cushion block disclosed in this solution optimizes the existing cushion block structure. The open design structure enables it to have spacing strength and positioning functions, and at the same time, it can be cast into a pier in cooperation with the existing repair process, optimizing the heightening operation process, effectively increasing the construction efficiency, and facilitating popularization and use.

[0017] Embodiment

[0018] A pier cushion block for overall heightening of multi-span concrete beams of a wharf, comprising: a top plate 1, a bottom plate 2 and a support plate assembly. The top plate 1 and the bottom plate 2 are rectangular plates with the same structure. A plurality of connecting and fixing holes 3 are provided at the same positions on the top plate 1 and the bottom plate 2. The top plate 1 and the bottom plate 2 are fixedly connected through the support plate assembly, and the space between the top plate 1 and the bottom plate 2 is communicated with the outside.

[0019] The support plate assembly includes a central support plate 4 and side support plates 5. The central support plate 4 is a cross-shaped support plate structure and is respectively connected to the horizontal center line and the vertical center line of the top plate 1 and the bottom plate 2. The side support plates 5 are correspondingly arranged at the positions of the short sides of the top plate 1 and the bottom plate 2.

[0020] The number of the connecting and fixing holes 3 is 4, and the connecting and fixing holes 3 are symmetrically arranged in pairs.

[0021] Each cushion block is connected by arranging fixing parts 6 on the connecting and fixing holes 3 of the adjacent top plate 1 and bottom plate 2.

[0022] The distance between the top surface of the top plate 1 and the bottom surface of the bottom plate 2 is 10 - 20 cm.

[0023] The top plate 1, the bottom plate 2 and the support plate assembly are made of steel material.

[0024] As Figure 1 shown, the working principle of the present utility model is as follows.

[0025] In the overall heightening and repair process of a concrete beam, a jacking device is used for gradual jacking. After each jacking stage, an appropriate number of cushion blocks are set at the bottom of the concrete beam to replace the jacking device as a support. In this solution, the cushion blocks are positioned and fixed by setting fixing parts 6 on the corresponding connection and fixing holes 3. The top plate 1 and the bottom plate 2 play the role of bearing force up and down, and the central support plate 4 and the two side support plates 5 play the role of support. Compared with conventional cushion blocks, the inside and outside of the cushion blocks in this solution adopt a connected design. After the jacking process is completed, concrete can be directly poured to form a heightened pier structure, which can effectively save additional processes, reduce maintenance costs, and is also more convenient for positioning and fixing during operation. The cushion block at the uppermost position in the figure is provided with a rubber bearing to contact the concrete beam. The cushion block at the lowermost position contacts the original cushion stone 7 through a positioning steel plate.

[0026] As Figures 2 - 3 shown, the central support plate 4 is a cross-shaped support plate structure for uniform stress, and the two side support plates 5 are used to further enhance the support function. The central support plate 4 and the two side support plates 5 connect the space between the top plate 1 and the bottom plate 2 to the outside, facilitating later pouring and forming.

[0027] Preferably, the overall thickness of the cushion block is preferably 10 cm and 20 cm, which is suitable for the jacking dimensions in stages.

[0028] The embodiments of the present invention have been described in detail above, but the above content is only the preferred embodiments of the present invention and cannot be considered as limiting the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of the application of the present invention should still fall within the scope covered by the patent of the present invention.
