Description

Technical Field

[0001] This utility model belongs to the field of bridge construction technology, and relates to the construction of high bridge piers, specifically to a prefabricated ladder cage wall-attached connection device for high pier construction. Background Technology

[0002] When constructing high bridge piers, after the pier reaches a certain height, a ladder cage needs to be set up next to the pier as a safe passage for construction workers to go up and down. In accordance with the specifications, a wall-attached connection needs to be set between the ladder cage and the pier to increase the stability of the ladder cage.

[0003] In the conventional method of attaching ladder cages to the wall, embedded parts are installed on the side walls during the construction of each segment of the pier. As the pier rises, the ladder cage is raised accordingly, and wall-attaching rods are welded between the ladder cage and the embedded parts of the pier. This method requires high-altitude welding, and when the ladder cage is dismantled after the pier construction is completed, the wall-attaching rods need to be cut, which will damage the ladder cage and the wall-attaching parts, affecting its reuse. Summary of the Invention

[0004] The purpose of this utility model is to address the above-mentioned problems by providing a prefabricated ladder cage wall-mounted connection device, which improves the wall-mounted installation efficiency and avoids damage to the ladder cage.

[0005] The technical solution of this utility model is as follows:

[0006] A prefabricated ladder cage wall-mounted connection device is characterized by comprising a clamp, 1-2 wall-mounted rods, and a wall-mounted rod connecting bolt. The clamp includes two clamp plates, one of which has an upper limit plate and a lower limit plate welded to its outer wall. The two clamp plates are fastened to the uprights of the ladder cage and fixed by the clamp bolt. One end of the wall-mounted rod is located between the upper limit plate and the lower limit plate. The clamp connecting bolt vertically penetrates the upper limit plate, the wall-mounted rod, and the lower limit plate. The lower end of the wall-mounted rod connecting bolt is screwed with a wall-mounted rod fastening nut on the bottom surface of the lower limit plate.

[0007] This utility model adopts a detachable connection structure with the ladder cage, which is convenient for installation and disassembly without welding. It can reduce damage to the ladder cage and wall-mounted components, improve the turnover rate of the ladder cage and wall-mounted components, and can flexibly adapt to various specifications of wall-mounted rods, with good versatility.

[0009] Figure 2 This is a schematic diagram of the planar structure of this utility model;

[0010] Figure 3 yes Figure 1 A schematic diagram of the structure of the T-nut. Detailed Implementation

[0011] like Figure 1 , Figure 2 , Figure 3 The present invention includes a clamp 1, 1-2 wall-mounted rods 2, and a wall-mounted rod connecting bolt 3. The clamp 1 includes two clamp plates, one of which has an upper limit plate 4 and a lower limit plate 5 welded to its outer wall. The two clamp plates are fastened to the uprights 6 of the ladder cage and fixed by the clamp bolt. One end of the wall-mounted rod 2 is located between the upper limit plate 4 and the lower limit plate 5. The clamp connecting bolt 4 vertically penetrates the upper limit plate 4, the wall-mounted rod 2, and the lower limit plate 5. The lower end of the wall-mounted rod connecting bolt 3 is screwed to the bottom surface of the lower limit plate with a wall-mounted rod fastening nut 7.

[0012] The clamp 1 can be configured according to the cross-sectional structure of the ladder cage column. When the ladder cage column is a circular tube, a circular clamp is used, such as... Figure 1 , Figure 2 In the embodiment shown, the ladder cage column 6 is a square tube, and the clamp 1 is a square clamp.

[0013] When using this utility model, one end of the wall-mounted rod 2 is first connected and fixed to the embedded part on the pier body. Then, the installation height of the clamp on the ladder cage column is adjusted according to the height of the wall-mounted rod. The other end of the wall-mounted rod 2 is inserted between the upper limit plate 4 and the lower limit plate 5 on the clamp and then connected and fixed by the wall-mounted rod connecting bolt. Finally, the clamp 1 is fixed on the ladder cage column 6.

[0014] In actual construction, the wall-mounted rod 2 may have various specifications and sizes. In the specific implementation of this utility model, the distance between the upper limit plate 4 and the lower limit plate 5 on the clamp can be set according to the size of the largest wall-mounted rod. When installing the clamp, insert the wall-mounted rod between the upper and lower limit plates, and first ensure that the upper limit plate presses against the top surface of the wall-mounted rod. If there is a gap between the bottom surface of the wall-mounted rod and the lower limit plate, a pad 8 can be set between the lower limit plate 5 and the wall-mounted rod 2. The clamp connecting bolt passes through the lower pad and the lower pad 8 is pressed against the wall-mounted rod 2 to ensure the stability of the wall-mounted rod structure.

[0015] Furthermore, to ensure that the lower pad is tightly against the wall-mounted rod, such as Figure 3 and Figure 1 As shown, the wall-mounted rod fastening nut 7 can be a T-nut, with the diameter of one end being smaller than the diameter of the other end. The smaller diameter end of the wall-mounted rod fastening nut 7 is passed through the lower limiting plate 5 and pressed against the bottom surface of the lower pad plate 8.

[0016] In actual construction, one or two wall anchors may be used at the same location. For example... Figure 1In the embodiment shown, there are two wall-mounted rods 2, which are arranged parallel to each other with a certain gap. When installing this utility model, first press the upper limit plate 4 against the top surface of the upper wall-mounted rod 2, insert the middle pad 9 into the gap between the two wall-mounted rods, press the middle pad against the upper and lower wall-mounted rods, and then tighten the wall-mounted rod fastening nut 7 to press the lower pad 8 against the bottom surface of the lower wall-mounted rod 2.
