[0021] like Figure 1 As shown, a lattice column positioning device for supporting in a foundation pit of a preferred embodiment of the utility model is used to vertically install the lattice column in a steel cage and prevent the lattice column from tilting due to the external force of concrete when pouring concrete. The device includes a circular ring and a limiting ring, wherein the limiting ring and the circular ring are coaxially arranged with the lattice column, and the limiting ring is detachably arranged above the circular ring. Specifically, the circular ring is sleeved outside the steel cage and is generally fixed by welding and the steel cage. In order to facilitate the positioning of the lattice column, a square limiting hole corresponding to the shape of the lattice column is opened in the middle of the limiting ring, and the lattice column is inserted into the square limiting hole. Further, in order to facilitate the installation and fixation between the limiting ring and the circular ring, the circumferential side wall of the limiting ring extends radially outward along the limiting ring to form a connecting portion, a fixing hole is opened on the connecting portion, and a threaded hole corresponding to the fixing hole is opened on the circular ring. The circular ring and the limiting ring are detachably connected by screws.

[0022] In some embodiments, in order to facilitate the processing of the ring and reduce the processing cost, the ring includes two symmetrically arranged semi-circular ring bodies, and the two semi-circular ring bodies are detachably connected. Figure 2 , Figure 3 as well as Figure 4, the semicircular ring body includes a first ring body, a second ring body, a first ear plate, and a second ear plate, wherein the first ring body is located above the second ring body and is coaxially arranged with the second ring body, the lower end face of the first ring body is perpendicular to the side wall of the second ring body, a threaded hole is opened at the upper end of the first ring body, first ear plates are arranged at both ends of the upper end face of the first ring body, second ear plates are arranged at both ends of the outer wall of the second ring body, and connecting holes are arranged on the first ear plate and the second ear plate. When the two semicircular ring bodies are installed, the two first ring bodies are coaxially arranged, and the first ear plates of the two first ring bodies are fitted and aligned, the two second ring bodies are also coaxially arranged, and the second ear plates on the two second ring bodies are fitted and aligned, and they can be tightened and fixed by bolts, which is convenient for disassembly and assembly. Furthermore, in order to enhance the structural strength of the semicircular ring body, a reinforcing plate is connected between the lower end face of the first ring body and the outer wall of the second ring body. Refer to Figure 3 The reinforcing plate has a triangular shape. To ensure good structural strength, the number of reinforcing plates is at least 3. In this embodiment, the number of reinforcing plates is preferably 3. To ensure the connection strength of the overall structure of the semicircular ring body, in this embodiment, welding is used to fix the first ear plate and the first ring body, the second ring body and the second ear plate, and the first ring body, the second ring body and the reinforcing plate. Since the semicircular ring body and the steel cage need to be fixed by welding, in order to increase the welding area between the semicircular ring body and the steel cage and facilitate welding, in this embodiment, refer to Figure 3 The inner diameters of the first ring body and the second ring body are equal, that is, the inner wall of the first ring body and the inner wall of the second ring body are both in contact with the outer wall of the steel cage, which is convenient for simultaneous welding and fixing, increasing the welding area and enhancing the connection strength.

[0023] In this embodiment, in order to facilitate the design of the limit ring, refer to Figure 2 The shape of the limiting ring is rectangular, and the four side walls of the limiting ring partially extend outward along the radial direction of the circular ring to form a connecting portion. In some embodiments, the shape of the limiting ring can also be circular, and can be designed accordingly according to actual processing requirements. In some embodiments, in order to further improve the overall structural strength of the positioning device, the circular ring and the limiting ring are both made of stainless steel.

[0024] The installation process of the utility model is: first, two semi-circular ring bodies are sleeved outside the steel cage, and the two semi-circular ring bodies are fixedly connected by bolts, and then the circular ring is welded and fixed to the steel cage as a whole, and then the limit ring is fixed on the circular ring. The positioning device provided by the utility model can be evenly spaced outside the steel cage in the vertical direction, and the spacing is maintained at about 1m. The corresponding number can be adjusted according to the length of the lattice column to ensure the verticality of the lattice column during installation.

[0025] In summary, the embodiment of the utility model provides a positioning device for supporting lattice columns in a foundation pit, which is provided with a circular ring and a limiting ring. The limiting ring and the circular ring are coaxially arranged with the lattice column. The circular ring is fixedly sleeved outside the steel cage. A square limiting hole corresponding to the shape of the lattice column is opened in the middle of the limiting ring. The lattice column is inserted into the square limiting hole. The square limiting hole positions the installation position of the lattice column to ensure the verticality of the lattice column during installation. At the same time, the lattice column is prevented from tilting due to the external force of concrete during the concrete pouring process, thereby improving the construction quality of the lattice column. In addition, the circular ring and the limiting ring are detachably connected by screws, and the overall structure is simple, which is convenient for disassembly and assembly, and improves construction efficiency.

[0026] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention.
