In Fig. 1, the top of the U-shaped fixed bracket 2 is installed on the structural floor 9, and the beam at the bottom is used to bear the weight from the steel pipe. The two ends of the beam of the U-shaped fixed support 2 are respectively connected with a fixed support diagonal brace 3, and the other end of the fixed support diagonal brace 3 is also connected on the structural floor 9; The nine beams and the structural floor form a stable triangular structure.

In the utility model, the directional top brace 1 of suitable size is designed according to the shape and position of the structural steel 7 and the U-shaped fixed bracket 2, and then four directional top braces are individually welded on the upper and lower parts of the pipeline. The upper directional support unit, that is, the second directional support assembly 102, clamps the left and right sides of the structural steel 7 along the pipeline axis direction, while the lower directional support unit, that is, the first directional support assembly 101, clamps the U-shaped The left and right sides of the crossbeam of the fixing bracket 2 along the direction of the pipe axis are fixed, so as to realize the fixing of one end of the pipe.

Fig. 5 is a schematic diagram of installation of the guide bracket assembly 6 in the present invention; Fig. 6 is a partially enlarged schematic diagram of Fig. 5; Fig. 7 is a sectional view of IV-IV in Fig. 5 . As shown in Figures 5 to 7, the guide bracket assembly 6 is installed on the structural steel 7 or the structural floor 9, and it includes a U-shaped bracket channel steel 64 for carrying the weight of the steel pipe 4 and the internal fluid. On the crossbeam of steel 64, and is positioned at horizontal plane and is vertical with the crossbeam of U-shaped bracket channel steel 64, is provided with slide bearing bottom channel steel 61. The bottom channel steel 61 of the sliding support is one or more. 61 are parallel and close to each other. Two angle steels 62 are arranged symmetrically on both sides of the bottom channel steel 61 of the sliding support on the crossbeam length direction line of the U-shaped support channel steel 64, and the two angle steels 62 can be arranged next to the bottom channel steel 61 of the sliding support. But more preferably, there is a certain gap 63 between the angle steel 62 and the bottom channel steel 61 of the sliding support. In a specific implementation manner, the distance of the gap 63 on the longitudinal direction of the beam of the U-shaped bracket channel steel 64 is 0.1-3 mm. Pipeline 4, wooden bracket 8, flat steel hoop 8a, steel belt 8b and bolt 8c are arranged above the bottom channel steel 61 of the sliding support, wherein wooden bracket 8 is used for heat insulation of pipeline 4, and flat steel bracket The setting of the hoop 8a, the bolt 8c and the steel belt 8b makes the wooden bracket 8 closely connected with the pipeline 4, and the steel belt 8b at the bottom facilitates its welding with the channel steel 61 at the bottom of the sliding support. In FIG. 5 , multiple pipes 4 and corresponding guide bracket assemblies 6 are arranged in parallel on the same U-shaped bracket channel steel 64 . Those skilled in the art can understand that only one pipeline 4 can also be arranged on one U-shaped bracket channel steel 64 .

The bottom channel steel 61 of the sliding support is fixedly connected with the steel belt 8b, such as welding. When the pipeline expands with heat and contracts with cold, the bottom channel steel 61 of the sliding support drives the pipeline 4 to slide on the crossbeam of the U-shaped bracket channel steel 64, and the most important sliding way is to stretch back and forth along the axis of the pipeline. Of course, due to the existence of the gap 63, the bottom channel steel 61 of the sliding support can drive the pipeline 4 to move slightly in other directions on the horizontal plane. But in general, because of the setting of the guide bracket assembly 6, the pipeline in a certain distance near the pipeline connected by the guide bracket assembly 6 basically performs telescopic movement along the length direction of the pipeline when the pipeline expands with heat and contracts with cold, and does not Vibrates sharply at any angle on the horizontal plane.

In a specific embodiment, the bracket system includes a fixed bracket assembly M and N arranged in front of and behind the telescopic section 5 of the pipeline along the axial direction of the pipeline, and one fixed bracket assembly N and the telescopic section 5 are located between the fixed bracket assembly N and the telescopic section 5. One or more guide bracket components 6 between the fixed bracket component N and the telescopic joint 5 (in the direction of the pipeline axis) (for example, 30 to 50 meters) is much larger than the distance between the fixed bracket component M and the telescopic joint 5 The distance between them (for example, 1 to 5 meters). The bent pipe is connected near the end of the fixed bracket assembly M away from the telescopic joint 5. Due to the existence of the fixed bracket assembly M, this section of the pipe will not perform telescopic movement along the pipeline axis direction, and thus will not cause any damage to the bending section. Excessive horizontal thrust for pipes perpendicular to it, thereby avoiding damage to the pipe system and support system. Similarly, the bent pipe is connected near the end of the fixed bracket assembly N away from the telescopic joint 5. Due to the existence of the fixed bracket assembly N, this segment of the pipe will not perform telescopic movement along the pipeline axis direction, and thus will not be bent. Excessive horizontal thrust of the pipe perpendicular to it in the bend, thus avoiding damage to the pipe system and support system. And one or more guide bracket assemblies 6 between the fixed bracket assembly N and the expansion joint 5 can make a section of longer pipeline only roughly in the direction along the pipeline axis to do telescopic movement, but can not shake freely on the horizontal plane, This is thus conducive to the stability of the pipe system, the entire support system, as well as the structural steel 7 and the structural floor 9 .

In the present utility model, it is also preferable to keep all the exposed metal parts together with the pipelines insulated, so as to achieve the optimal design effect.
