Description

Technical Field

[0001] The utility model relates to the technical field of building engineering, in particular to an integral combined finished product heat-insulating fixed support. Background Art

[0002] At present, the domestic centralized heating hot water pipeline network has achieved a maximum transmission distance of 70km, and the steam pipeline network has achieved a maximum transmission distance of 20km. When high-temperature water or steam pipelines are transported over long distances, the heat loss of the pipeline network is large and the transmission efficiency is low. In order to make the pipeline network transmission distance longer and more efficient, more technical measures are taken during the design, such as: using insulation supports to reduce heat conduction during overhead laying. Among them, the insulation pipe supports are divided into sliding supports and fixed supports. The fixed supports are usually designed by the design institute as concrete piers, with steel plates embedded on the piers, and the insulation supports are welded and fixed on the steel plates.

[0003] When the pipeline system is heated and expanded, the fixed support does not move as a fixed point. It is subjected to the axial thrust of the pipeline, which is transmitted to the embedded steel plate through the steel insulation support. However, during on-site construction, the traditional method is to directly spot weld the reinforcement to the bottom of the embedded steel plate. Since the spot welding force contact area is small, during the operation of the fixed support, it is easy to be subjected to a large thrust from the pipeline, causing damage to the embedded steel plate and the reinforcement welding point, resulting in the upper welded structure of the embedded steel plate falling off from the concrete pier, resulting in operational safety accidents.

[0004] Therefore, an integral combined finished thermal insulation fixed support with high support strength is needed to solve the above problems. Utility Model Content

[0006] The utility model provides an integrally assembled finished product heat-insulating fixed support, aiming to solve the problem proposed in the background technology that the traditional method is to directly spot-weld the tie rods to the bottom of the embedded steel plate. Since the force contact area of ​​the spot welding is small, it is easy to have a large thrust from the pipeline, causing damage to the welding points of the embedded steel plate and the tie rods, resulting in the upper welding structure of the embedded steel plate falling off from the concrete pier, resulting in an operation safety accident.

[0031] The utility model provides an integral combined finished heat insulation fixed support, such as Figure 1-Figure 3 As shown, the fixed support includes a concrete pier 1 cast on the ground, an embedded steel plate 2 and a tie bar 3 embedded in the concrete pier 1, a support steel plate 4 welded to the embedded steel plate 2, and a heat insulation component 5 arranged on the side of the support steel plate 4 away from the embedded steel plate 2 and connected to the pipeline; the fixed support also includes a bendable reinforcement rib 6 arranged on one side of the tie bar 3 and an adjustment component 7 arranged on the tie bar 3 for adjusting the bending angle of the bendable reinforcement rib 6; the embedded steel plate 2 is provided with a through hole 21 for plug welding of the tie bar 3.

[0032] When in use, the tie rod 3 is first plug-welded in the perforation 21 of the embedded steel plate 2 in the factory in advance, and the adjustment component 7 and the bendable reinforcement rib 6 are installed on the tie rod 3. Then, on-site construction is carried out. During on-site construction, the concrete pier 1 can be poured at a determined position first. However, while pouring the concrete pier 1, the bending angle of the bendable reinforcement rib 6 can be adjusted using the adjustment component 7 according to the actual construction conditions of the concrete pier 1. After the adjustment, the embedded steel plate 2 and tie rod 3, as well as the adjustment component 7 and the bendable reinforcement rib 6 that have been plug-welded in advance are placed in the concrete pier 1 and poured together to form a stable concrete pier 1 structure.

At this time, the insulation material pad 54 on the first half steel ring 51 and the insulation material pad 54 on the second half steel ring 52 can fully wrap the pipeline. Finally, use the bolts 53 to fix the first half steel ring 51 and the second half steel ring 52, and the pipeline can be installed on the insulation component 5, so that the insulation component 5 can play an insulation effect to reduce the heat dissipation loss of the high-temperature pipeline transportation system.

[0035] In addition, in order to facilitate welding of multiple reinforcement bars 3, multiple through holes 21 are provided; the design of multiple through holes 21 can provide multiple welding positions, thereby facilitating simultaneous welding of multiple reinforcement bars 3 to improve the supporting strength of the concrete pier 1.
