[0016] The structure and principles of the present application are very clear to those skilled in the art. It should be understood that the specific embodiments described herein are only used to explain the present application and do not limit the present application.
[0017] Figure 1 FIG. 1 is a structural schematic diagram of one embodiment of a positioning fixture for reinforcing a concrete beam column according to the present application. In this embodiment, the positioning fixture can include a fixing part and a telescopic part. The fixing part can include a first clamping component, a first steel pipe 1, and a first circular steel plate 2, the first clamping component is fixedly connected to the first steel pipe 1, the first circular steel plate 2 is provided with a hole 3, the first circular steel plate 2 is fixedly connected and closes one end of the first steel pipe 1, the telescopic part can include a second clamping component, a second steel pipe 4, a lead screw 5, and a nut 6, the second clamping component is fixedly connected to the second steel pipe 4, the second steel pipe 4 is slidably arranged in the first steel pipe 1, the nut 6 is arranged outside the first circular steel plate 2, the lead screw 5 passes through the nut 6 and the hole 3, one end of the lead screw 5 is fixedly connected to the second steel pipe 4, and the other end is a free end, the nut 6 and the first circular steel plate 2 are used to adjust the distance between the first clamping component and the second clamping component. The object to be positioned in this embodiment can be a concrete formwork.
[0018] The basic structure of the large-size multifunctional positioning fixture provided in the present application includes a fixed part and an extension part. The fixed part is composed of a first clamping component, a first steel pipe 1, and a first circular steel plate 2, which together form a stable support structure. The extension part includes a second clamping component, a second steel pipe 4, a lead screw 5, and a nut 6, which allow the fixture to be adjusted in length to accommodate different sizes of formworks or construction requirements. By coordinating the nut 6 and the first circular steel plate 2, the distance between the first clamping component and the second clamping component can be precisely adjusted, thereby achieving firm positioning and reinforcement of the formwork. This design reduces the use of tie rods, reduces the generation of concrete holes 3, and improves the quality of concrete.
[0019] In addition, the extension part also includes a second circular steel plate 7, one side of which is fixedly connected to the lead screw 5, and the other side is fixedly connected and closed to one end of the second steel pipe 4. By adding the second circular steel plate 7 in the extension part, the structural strength of the extension part is enhanced, so that the fixture can still remain stable when subjected to greater pressure. At the same time, the second circular steel plate 7 also plays a role in further fixing the lead screw 5, preventing the lead screw 5 from loosening or falling off during use, thereby improving the reliability and safety of the fixture.
[0020] The first clamping component and the second clamping component each include a limiting steel plate 8 and a gasket 9, which is pasted to the limiting steel plate 8 for contacting the object to be positioned. One side of the gasket 9 is pasted to the limiting steel plate 8, and the other side is pasted with a contact steel plate for contacting the object to be positioned. This design allows the fixture to distribute pressure more evenly when clamping the formwork, preventing the formwork from being damaged due to excessive local stress. At the same time, the gasket 9 also plays a role in buffering and damping, reducing noise and vibration during construction. The presence of the contact steel plate further increases the contact area between the fixture and the object to be positioned, making the fixture more stable and reliable during positioning.

The first component can include the limiting steel plate 8, the gasket 9, the second circular steel plate 7 and the second steel pipe 4. The second component can include the lead screw 5 and the nut 6. The third component can include the limiting steel plate 8, the gasket 9, the first circular steel plate 2 and the first steel pipe 1. The difference between the inner diameter of the first steel pipe 1 and the outer diameter of the second steel pipe 4 is greater than 1 mm. The second component and the first component are welded together, and the connecting point is located at the axial position of the first steel pipe 1 and the second steel pipe 4. The lead screw 5 should not be too long, and the gasket 9 can be pasted with flexible material.
[0022] In addition, in optional embodiments, for an object to be fixed (for example, a concrete beam column in the shape of a cuboid) having four sides, the positioning fixture of the present application can include four positioning groups. One positioning group includes one fixing part and one telescopic part, and one positioning group is used to fix one side of the concrete beam column, thereby achieving reinforcement of the concrete beam column.
