Technical Field

[0001] The invention relates to the technical field of steel cages, in particular to a method for fixing and positioning a steel cage. Background Art

[0002] Steel cage is an important basic structure for foundation pit construction. The main function of steel cage is the same as the stress of the longitudinal steel bar of the column. During the construction process, the steel cage needs to be fixed inside the foundation pit to ensure its stability to ensure the pouring quality of concrete. However, in order to further improve the quality of construction, it is necessary to have higher requirements for the position of the steel cage relative to the center of the surroundings in the foundation pit. The existing steel cage adopts the center position positioning setting method, which is mostly carried out by manual visual inspection. However, the foundation pit is not a pure cylindrical foundation, which causes it to be relatively poor in the center position at the pit mouth. After searching the steel cage fixing device, some fixing device technologies are applied, such as a steel cage fixing device for building foundation pit (authorization announcement number CN212742553U), and it is found through the actual operation of on-site construction that the adjustment and fixation of its center position and other construction operability and practicality are still poor. Therefore, those skilled in the art provide a steel cage fixing device arranged at the foundation pit mouth and a steel cage fixing and positioning method based on the device to solve the problems raised in the above-mentioned background technology.

[0031] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the present embodiment proposes a method for fixing and positioning a steel cage, including a foundation pit 5 and a steel cage 4 arranged inside the foundation pit 5, and a steel cage fixing device, wherein the device includes a positioning sleeve 1 arranged at the inner foundation pit opening of the foundation pit 5 and outside the steel cage 4, a fixing groove 11 is symmetrically opened on the inner side of the positioning sleeve 1, and a first electric telescopic rod 21 is symmetrically arranged on the outer side of the positioning sleeve 1, a positioning plate 2 is arranged inside the fixing groove 11, and a positioning tooth 22 is symmetrically arranged on the inner side of the positioning plate 2, and a second electric telescopic rod 32 is also installed on the outer side of the positioning sleeve 1, and the second electric telescopic rod The telescopic end of 32 is provided with a fixing plate 3 outside the positioning sleeve 1, and the outer surface of the fixing plate 3 is symmetrically provided with positioning pins 31. The operation of the first electric telescopic rod 21 will make the positioning plate 2 telescopically move toward the inside of the positioning sleeve, and make the positioning teeth 22 embedded in the gap outside the steel cage 4, so as to achieve the purpose of positioning, fixing and connecting the steel cage 4, and through the extension and contraction of the second electric telescopic rod 32, the fixing plate 3 is brought into contact with the inner wall of the foundation pit 5 to ensure the center position adjustment operation and stability of the positioning sleeve 1, and finally facilitate the purpose of fixing the center position of the steel cage 4.

[0032] like Figure 1 and Figure 3 As shown, further, two locating pins 31 are arranged at symmetrical positions on the outside of the fixing plate 3, and the ends of the locating pins 31 are arranged in a conical shape. This arrangement utilizes the locating pins 31 to be inserted into the inside of the foundation pit, thereby ensuring the center position and stability of the fixing plate 3, thereby achieving the purpose of fixing the center position of the locating sleeve 1.

[0033] like Figure 3 As shown, a connecting sleeve 33 is provided at the middle position of the inner side of the fixed plate 3, the telescopic end of the second electric telescopic rod 32 is embedded in the connecting sleeve 33 and connected by bolts, and the fixed end of the second electric telescopic rod 32 is installed on the outer surface of the positioning sleeve 1 by bolts. This arrangement can connect the second electric telescopic rod 32 with the connecting sleeve 33 by bolts, so that the telescopic movement of the second electric telescopic rod 32 will cause the fixed plate 3 to move outward.

[0034] like Figure 1 As shown, as a preferred embodiment, on the basis of the above method, further, the fixing plate 3 is arc-shaped and the positioning sleeve 1 is hollow cylindrical. This arrangement utilizes the hollow arrangement of the positioning sleeve 1 to facilitate the insertion of the steel cage 4 into its center, further facilitating the purpose of fixing the center position of the steel cage 4.
