Description

Technical Field

[0001] This utility model relates to the field of air conditioning water riser support technology, specifically a sliding and guiding support for large-diameter ultra-high air conditioning hot and cold water risers. Background Technology

[0002] With the increasing number of super high-rise buildings, some traditional practices have gradually revealed their drawbacks and no longer meet the needs of construction and operation. Super high-rise buildings have large terminal load demands, and the required flow rate is even greater under conventional supply and return water temperature differences. Since pipe resistance is positively correlated with medium flow velocity, larger pipe diameters are required when the medium flow velocity cannot be increased. The ultra-large risers of each system occupy more area, reducing the effective usable area of ​​the building. In order to improve the building's area utilization and reduce the space occupied by pipe shafts, it is necessary to reduce the pipe diameter and increase the temperature difference to meet the terminal load demands. Therefore, large temperature difference air conditioning water systems have emerged.

[0003] The greater the difference between the operating temperature and the installation temperature of the air conditioning chilled and hot water risers, the greater the thermal expansion and contraction, and the greater the axial movement. Conventional wooden supports with flat steel profiles, which also function as guide and sliding brackets, are less suitable. Figure 1 As shown, the wooden support can easily detach from the flat steel and fall off as the pipe moves axially, causing the riser to tilt uncontrollably without support. If the tilt is severe, the interface between the riser and the branch pipe may leak or even crack and burst.

[0004] To avoid such situations, a new type of support is needed to ensure safety and reliability during axial movement of the riser. Utility Model Content

[0005] To address the technical problems in the prior art, this utility model provides a guide support for large-diameter air conditioning hot and cold water risers, ensuring the safe and stable operation of the pipeline.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A guide bracket for large-diameter air conditioning hot and cold water risers is used to support and guide the riser body. It includes a square steel frame fitted around the riser body. Ribs are welded to the outer side wall of the riser body at the four inner side walls of the steel frame. The ribs abut against the inner side wall of the steel frame. Heat-insulating and wear-resistant gaskets are provided on the inner side wall of the steel frame at the locations corresponding to the ribs. The heat-insulating and wear-resistant gaskets are fixed to the steel frame with bolts.

[0008] Preferably, a supporting plate is welded to one side of the rib corresponding to the heat-insulating and wear-resistant pad.

[0009] Preferably, the heat-insulating and wear-resistant gasket is U-shaped with the opening facing away from the riser body and is sleeved on the outside of the steel frame. The heat-insulating and wear-resistant gasket is provided with clamping steel plates on the upper and lower sides of the steel frame, and the bolts pass vertically through the clamping steel plates on the upper and lower sides of the steel frame to fix the heat-insulating and wear-resistant gasket to the steel frame.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] This utility model provides a guide support for large-diameter air conditioning hot and cold water risers, replacing the traditional wooden support with ribs welded to the riser body. This solves the problem that the wooden support is prone to falling off and causing operational instability when using traditional supports for risers with large thermal expansion and contraction. At the same time, the steel frame is equipped with heat-insulating and wear-resistant gaskets at the corresponding ribs to prevent temperature from being transferred to the steel frame along with the pipe, thus avoiding temperature differences and condensation. It also reduces the loss of heat and cold. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please refer to Figures 2-4. This application proposes a guide bracket for a large-diameter air conditioning hot and cold water riser for supporting and guiding the riser body 1. It includes a square steel frame 2 sleeved on the outside of the riser body 1. Ribs 3 are welded to the outer side wall of the riser body 1 at the four inner side walls of the steel frame 2 respectively. The ribs abut against the inner side wall of the steel frame 2. Heat-insulating and wear-resistant pads 4 are provided on the inner side wall of the steel frame 2 at the ribs 3. The heat-insulating and wear-resistant pads 4 are fixed to the steel frame 2 by bolts 5.

[0019] Specifically, ribs 3 are welded to the four inner side walls of the steel frame 2 on the outer side wall of the riser body 1, replacing the traditional wooden support. This prevents the riser body 1 from falling off when it expands and contracts due to the thermal expansion and contraction of the air conditioning water. At the same time, heat-insulating and wear-resistant gaskets 4 are provided on the inner side wall of the steel frame 2 at the ribs 3 to prevent wear on the steel frame 2 and to prevent temperature difference from forming on the steel frame 2 along with the pipe, which would cause condensation. This also reduces the loss of heat and cold.

[0020] Further details can be found here. Figure 2-4 A support plate 6 is welded to one side of the rib 3 corresponding to the heat insulation and wear-resistant pad 4 to increase the stress area and reduce the wear of the heat insulation and wear-resistant pad 4.

[0021] Further details can be found here. Figure 2-4 The heat-insulating and wear-resistant gasket 4 here is U-shaped with the opening facing away from the riser body 1, and is sleeved on the outside of the steel frame 2. The heat-insulating and wear-resistant gasket is provided with clamping steel plates 7 on the upper and lower sides of the steel frame 2 respectively. The bolts 5 pass vertically through the clamping steel plates 7 on the upper and lower sides of the steel frame to fix the heat-insulating and wear-resistant gasket 4 on the steel frame 2.

[0022] The setting of the clamping steel plate 7, together with the U-shaped heat-insulating and wear-resistant gasket 4, increases the stress area when it is fixed to the steel frame 2 by bolts 5, and avoids the bolts 5 from accelerating the damage to the heat-insulating and wear-resistant gasket 4. At the same time, the entire guide bracket is made of conventional materials that are easy to obtain, low in cost, and convenient for on-site fabrication and installation.
