[0002] The pipe gallery is used to arrange pipelines. Many pipelines are concentrated together and installed in an orderly manner in the pipe gallery. The pipe gallery is composed of columns, beams and trusses of steel or reinforced concrete structures, and can be divided into single-layer or multi-layer according to type.

[0003] In the related technology, it was found through searching that a solution of a multi-angle adjustable bracket for an arc-shaped pipeline corridor without pre-embedded and anchored bolts (Announcement No. CN214119177U) can support the double-piece 41*41 steel, making the whole structure more reliable and much safer. The structure of the multi-angle adjustable bracket for an arc-shaped pipeline corridor without pre-embedded and anchored bolts is simple and easy to operate, which is better than the traditional method.

[0004] However, the HALFEN channel of the above solution is circular, and the angle connector is approximately triangular. When the angle connector is fixed to the HALFEN channel by T-bolts and nuts, the nuts need to be tightened to prevent the angle connector from sliding down. The tightening force of the nuts is required to be high. If the pipeline is heavy or the nuts are loose, the angle connector will easily slide down along the HALFEN channel, and the support for the pipeline will decrease. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Example:

[0020] See also Figure 1-3 The utility model provides a technical solution: an adjustable arc-shaped embedded groove bracket system, comprising an embedded groove 1, a T-shaped back plate 2 is movably mounted on the embedded groove 1, a bracket 3 is fixedly connected to the T-shaped back plate 2, and the embedded groove 1 and the T-shaped back plate 2 are arranged in an arc shape, so that the T-shaped back plate 2 fits better with the embedded groove 1, and prevents the T-shaped back plate 2 from sliding down;

[0021] T-shaped rivets 7, wherein a plurality of T-shaped rivets 7 are provided and the T-shaped rivets 7 are fixedly connected to the embedded groove 1. The T-shaped rivets 7 extend deep into the concrete 8, and have a stronger fixing effect on the embedded groove 1, thereby improving the ability of the bracket 3 to carry the pipe;

[0022] The facing surfaces of the embedded groove 1 and the T-shaped back plate 2 are both provided with V-shaped teeth 6, and the teeth on the embedded groove 1 and the T-shaped back plate 2 are mutually engaged, thereby increasing the contact surface between the embedded groove 1 and the T-shaped back plate 2, improving the sliding friction, and better limiting the sliding of the T-shaped back plate 2.

[0023] In this embodiment, if Figure 3 As shown, the surface of the T-shaped rivet 7 is coated with concrete 8, and a steel frame 9 is provided in the concrete 8. The concrete 8 will generate temperature stress and shrinkage stress during the solidification process, which may cause the concrete 8 to crack. The steel frame 9 can effectively resist these stresses, reduce the risk of cracking, and thereby improve the supporting and fixing force of the concrete 8 on the embedded groove 1.

[0024] In this embodiment, if Figure 1 As shown, the embedded groove 1 has a slide groove, and the slide groove is provided with a T-shaped bolt 4, the T-shaped bolt 4 passes through the T-shaped back plate 2 and the T-shaped bolt 4 is installed with a fixing part, one end of the T-shaped bolt 4 is inserted into the embedded groove 1, and then the T-shaped back plate 2 is put on the T-shaped bolt 4, and the embedded groove 1 and the T-shaped back plate 2 can be connected using a nut 13, and the gasket 11 and the spring washer 12 are located on the same side of the T-shaped back plate 2.

[0025] In this embodiment, if Figure 1 As shown, the T-shaped back plate 2 has a hole seat 10, and the support arm 3 is sleeved on the outside of the hole seat 10. A hexagonal bolt 5 that passes through the hole seat 10 is inserted into the surface of the support arm 3, and a fixing part is also installed on the hexagonal bolt 5 to achieve a fixed connection between the support arm 3 and the hole seat 10. The gasket 11 and the spring washer 12 are respectively located on both sides of the support arm 3.

[0026] In this embodiment, if Figure 1As shown, the fixing member includes a gasket 11, a spring washer 12, and a nut 13. After the nut 13 is tightened, the spring washer 12 and the gasket 11 will give the nut 13 an elastic force, making it difficult to fall off, thereby enhancing the anti-loosening performance of the nut 13.

[0027] In this embodiment, if Figure 2 As shown, the surface of the support arm 3 is provided with a notch slide 14, and the clamp can be fixedly connected inside the notch slide 14, and the use of the clamp has a better fixing effect on the pipeline.

[0028] Specifically, when using, when pouring concrete 8, the embedded groove 1 and the T-shaped rivet 7 are deeply inserted into the steel frame 9, such as Figure 3 As shown, after the concrete 8 solidifies, the embedded groove 1 is supported and fixed, the T-shaped bolt 4 is inserted into the embedded groove 1, and the T-shaped bolt 4 passes through the T-shaped back plate 2, and the T-shaped back plate 2 and the embedded groove 1 are pre-fixed;

[0029] Next, adjust the height of the T-shaped back plate 2 as needed. When adjusting, first loosen the two nuts 13, then move the T-shaped back plate 2, and the T-shaped back plate 2 drives the T-shaped bolt 4 to slide in the embedded groove 1. When the height is appropriate, tighten the nut 13 to make it stably threaded with the T-shaped bolt 4, so that the V-shaped teeth 6 on the T-shaped back plate 2 and the V-shaped teeth 6 on the embedded groove 1 are firmly engaged to prevent the T-shaped back plate 2 from sliding down, which has a better supporting effect on the pipeline and is less likely to lose the supporting force.
