Technical Field
[0001] The utility model relates to the technical field of bridge construction devices, in particular to a detachable connecting and attaching device for a ladder cage and a pier column. Background Art
[0002] During bridge construction, a ladder cage needs to be installed next to the pier to facilitate construction workers climbing to higher ground for construction. When using the ladder cage as a pedestrian safety passage, if the height exceeds 15 meters and is not connected to the pier, the ladder cage will shake significantly. To ensure safety, an attachment structure must be installed. The existing attachment structure uses steel bars for tensioning. The disadvantages of this method are: it is inconvenient to assemble and disassemble, has many welding points during installation, has poor performance, is costly, and requires cutting off the pier fixing points during disassembly, which is not only troublesome but also increases the risk of removing the fixing points. To this end, people have developed detachable ladder cage connection and attachment devices, such as the Chinese patent application "Ladder Cage Attachment Safety Connection Device," application number: 202222613518.5, application date: September 30, 2022. Abstract: The utility model provides a ladder cage attachment and safety connection device, characterized by comprising a connecting rod, a first connecting seat, and a second connecting seat. The middle section has threaded holes at both ends. The connecting rod comprises a first section, an middle section, and a second section, which are sequentially connected. One end of the first section is provided with a first screw that matches the threaded hole at one end of the middle section. The other end of the first section is provided with a first mounting portion that connects to the first connecting seat. The first connecting seat is connected to the ladder cage. One end of the second section is provided with a second screw that matches the threaded hole at the other end of the middle section. The other end of the second section is provided with a second mounting portion that connects to the second connecting seat. The second connecting seat is connected to the pier. By separating the connecting rod into the first, middle, and second sections, the length of the connecting rod can be easily adjusted, thereby adjusting the distance between the ladder cage and the bridge pier, making installation more convenient. The tightness of the connecting rod can also be easily adjusted during installation, facilitating construction.
[0003] In highway bridge design, double or triple piers are commonly used for piers below 40 meters in height. Square, thin-walled hollow piers are commonly used for piers between 40 and 80 meters. Solid piers are also available, with square, thin-walled hollow piers accounting for a larger proportion. Although the aforementioned attachment and connection device utilizes a detachable structure, it utilizes a clamp to connect to the pier column, making it inconvenient to connect to square, thin-walled hollow pier columns. Therefore, a new design of a detachable attachment and connection device for the ladder cage and pier column is needed. Summary of the Invention
