Description

Technical Field

[0001] This utility model belongs to the field of road and bridge expansion joints, and specifically relates to a road and bridge expansion joint protection device. Background Technology

[0002] Road expansion joints are the connecting parts between buildings, bridges, and road surfaces. They are important components that play a buffering role in preventing deformation and damage caused by different coefficients of thermal expansion of different parts. Expansion joints play a crucial role in protecting road and bridge structures from damage. They can absorb the expansion and contraction deformation of bridges caused by temperature and load changes. Without expansion joints, excessive stress would be generated when the road and bridge pavement expands and contracts with temperature changes, leading to structural damage. Expansion joints can effectively protect the integrity and safety of roads and bridges. However, existing expansion joints are often too narrow during use, leading to increased internal stress and loss of free expansion and contraction capacity. In addition, the lack of protection makes expansion joints prone to damage.

[0003] Therefore, in view of the shortcomings of the above-mentioned solutions in actual production and implementation, modifications and improvements have been made. At the same time, in the spirit and concept of seeking excellence, with the assistance of professional knowledge and experience, and after much ingenuity and experimentation, this utility model was created to provide a road and bridge expansion joint protection device to solve the problem. Utility Model Content

A connecting cylinder is connected to the upper part of the end fixing block. An adjusting block is installed inside the connecting cylinder. An end sealing ring is provided on the inner side of the connecting cylinder.

[0006] In a preferred embodiment, the first protective beam and the second protective beam are symmetrically distributed, and the interior of the first protective beam and the second protective beam is provided with a circular through hole, which facilitates the installation of the end fixing block inside the first protective beam and the second protective beam.

The upper part of the end fixing block 8 is connected to the connecting cylinder 9. An adjusting block 10 is installed inside the connecting cylinder 9 so that the adjusting block 10 can move inside the connecting cylinder 9, thereby achieving the purpose of protecting the expansion joint of the first protective beam 1 and the second protective beam 2. An end sealing ring 11 is provided on the inner side of the connecting cylinder 9. The end sealing ring 11 can improve the sealing between the connecting cylinder 9 and the adjusting block 10.

[0020] Furthermore, the first protective beam 1 and the second protective beam 2 are symmetrically distributed, and the interior of the first protective beam 1 and the second protective beam 2 is provided with circular through holes, which facilitates the installation of the end fixing block 8 inside the first protective beam 1 and the second protective beam 2.

[0021] Furthermore, the first protective beam 1 and the second protective beam 2 are fixedly connected to the ends of the first support rod 3 and the second support rod 4, so that the first support rod 3 and the second support rod 4 can be fixed to the lower part of the protective beam.

[0022] Furthermore, the interior of the connecting cylinder 9 is hollow, and the connecting cylinder 9 is movably connected to the adjusting block 10, so that the adjusting block 10 can move inside the connecting cylinder 9.

[0023] Furthermore, the end of the adjusting block 10 is connected to the connecting cylinder 9 through a buffer mechanism, which can reduce the force between the adjusting block 10 and the connecting cylinder 9.
