[0030] Example one:
[0031] As Figures 1-4 As shown, a reinforcing steel positioning device for building construction, including the base 1, the upper portion of the base 1 is provided with a limiting plate 4, the surface of the limiting plate 4 is provided with a plurality of positioning grooves, and the second positioning column 11 is provided in the positioning groove, the surface of the second positioning column 11 is provided with a positioning sleeve 5, the inner side of the positioning sleeve 5 is provided with a clamping ring 9, and the second positioning column 11 is clamped through the clamping ring 9, the surface of the positioning sleeve 5 is provided with an adjusting bolt 10, the top of the positioning sleeve 5 is provided with a guide ring 6 through the clamping groove 7 and the clamping block 8, the positioning sleeve 5 is sleeved on the second positioning column 11, and the position is fixed through the adjusting bolt 10, at the same time, the guide ring 6 is installed on the top of the second positioning column 11 by using the clamping groove 7 and the clamping block 8, then the reinforcing steel is inserted into the guide ring 6 and passes through the first positioning column 2 and the second positioning column 11, then the reinforcing steel is positioned by tightening the fastening bolt 3, and the stability of the reinforcing steel in the construction process is ensured. In this process, due to the existence of the positioning sleeve 5, the reinforcing steel positioning device can accurately position reinforcing steel of different lengths, thereby improving the positioning accuracy of the reinforcing steel, and further improving the use convenience and practicality of the reinforcing steel positioning device for building construction.
[0032] Referring to Figure 1 , Figure 2 , the positioning grooves and the second positioning columns 11 are provided in multiple groups and correspond to each other, and are arranged in a rectangular array, which improves the construction efficiency. At the same time, these positioning grooves and second positioning columns 11 are arranged in a rectangular array, which ensures the uniform distribution and accurate alignment of the reinforcing steel in the three-dimensional space, avoids the mutual interference between the reinforcing steels, and improves the overall structural stability of the reinforcing steel cage. The arrangement of multiple groups of positioning grooves and second positioning columns 11 also enhances the versatility of the device, so that it can adapt to the requirements of reinforcing steel cage preparation of different sizes and shapes.
[0033] Referring to Figure 1 , Figure 2 , the guide ring 6 is in the shape of a horn, and the material of the guide ring 6 is aluminum alloy, which can effectively guide the reinforcing steel to be smoothly inserted into the positioning column, reduce the friction and resistance of the reinforcing steel in the insertion process, and improve the construction efficiency.

At the same time, the cooperative work of the plurality of electric push rods 12 ensures the stability and safety of the device during lifting.
[0036] Referring to Figure 1 , Figure 2 A plurality of first positioning columns 2 are arranged on the top of the base 1, and the first positioning column 2 and the second positioning column 11 are arranged at the same center, so that the steel bars can maintain concentricity when inserted into the positioning column, ensuring the overall structural stability and symmetry of the reinforcement cage during the preparation process.
