Description

Technical Field

[0001] This invention relates to the field of thermal gas pipeline technology, and in particular to a lateral anti-fall structure for thermal pipelines. Background Technology

[0002] Thermal pipelines are used to transport thermal energy media such as steam or hot water. They are characterized by high temperatures, high pressures, and high flow rates, resulting in significant expansion and impact forces during operation. Furthermore, installation errors can occur during pipeline installation, potentially causing the pipeline axis to shift. Especially during operation, the expansion and impact forces from the medium generate axial forces, easily leading to lateral displacement. In earthquake conditions, seismic forces perpendicular and parallel to the pipeline act, with the perpendicular force also causing lateral displacement. Therefore, lateral baffles are required on the outer side of thermal pipelines. In existing technologies, thermal pipelines are typically installed on steel supports using existing sliding brackets, with the lateral baffles welded to the supports. This method requires welding during installation, affecting construction progress, and the welded side baffles are prone to stress concentration at the weld points over long-term use, reducing their service life. Summary of the Invention

[0003] The purpose of this invention is to provide a method for laterally limiting the movement of a heating pipe by pre-casting a concrete support anti-fall component, thereby avoiding the need for welding side baffles during the later installation of the heating pipe.

[0004] The present invention is achieved through the following measures: a lateral anti-fall structure for a thermal pipeline, characterized in that it includes a concrete support and anti-fall components symmetrically arranged on both sides of the concrete support. The protective components include an upper vertical plate, a lower vertical plate, and an upper horizontal plate connecting the bottom end of the upper vertical plate and the top end of the lower vertical plate. A lower horizontal plate is provided on the outer side of the lower vertical plate facing the upper vertical plate and parallel to the upper horizontal plate. The lower horizontal plate, lower vertical plate, and upper horizontal plate are embedded in the concrete support; The upper slab is partially or completely exposed above the concrete support.

[0005] Furthermore, the exposed height of the upper plate is at least half the height of the sliding support.

[0006] Furthermore, the upper upright plate, lower upright plate, upper horizontal plate, and lower horizontal plate are integrally manufactured or welded together.

[0007] Furthermore, at least one sleeve is fixedly provided on the lower end surface of the upper horizontal plate. The sleeve can be inserted into the reinforcing bars of the concrete support. The sleeve can be designed according to the spacing of the main reinforcing bars of the reinforcing cage and is generally fixed by welding. Alternatively, at least one U-shaped clip is fixedly provided on the lower end surface of the upper horizontal plate. The U-shaped clip can be clipped into the reinforcing bars of the concrete support. The U-shaped clip can be designed according to the spacing of the main reinforcing bars of the reinforcing cage and is generally fixed by welding. The U-shaped clip is suitable for situations where the upper end of the main reinforcing bar is bent inward. The U-shaped clip can be made by opening a U-shaped groove in the middle of a steel pipe or by directly bending a steel plate into a U-shape.

[0008] Furthermore, the lower horizontal plate is fixedly connected to the reinforcing steel of the concrete support.

[0009] Furthermore, the contact length between the fall arrestor and the concrete support is at least one-third of the width of the sidewall of the concrete support.

[0010] Furthermore, it also includes an embedded plate located above the upper horizontal plate, the embedded plate being pressed onto the upper horizontal plate and connected to the reinforcing bars of the concrete support via vertical bars.

[0011] Furthermore, a support bar is provided on the steel reinforcement of the concrete support and below the lower horizontal plate.

[0012] Furthermore, the fall arrestor is generally made of metal, typically Q235B carbon structural steel or higher grade steel.

[0013] Usage: Tie the reinforcing cage to the concrete support, insert the sleeve onto the main reinforcement bars of the cage, and after installation, weld the support bars onto the main reinforcement bars below the lower horizontal plate to position the anti-fall component. Place the embedded plate on the upper horizontal plate and weld the vertical bars on the embedded plate to the reinforcing cage. Finally, install the formwork on the outside of the reinforcing cage for pouring. The spacing and number of main reinforcement bars depend on the actual situation.

[0014] When the sleeve is not available, the lower horizontal plate can be directly welded onto the reinforcing cage.

[0015] The beneficial effects of the technical solution provided by this invention are as follows: the fall arrestor is pre-cast onto the concrete support, and the fall arrestor is fixedly connected to the reinforcing steel bars in the pre-concrete support to form an integral load-bearing component, enhancing the combined load-bearing capacity of the fall arrestor components on both sides, and jointly limiting the lateral movement of the sliding support to prevent lateral displacement. The fall arrestor is a hook-shaped component formed by an upper vertical plate, an upper horizontal plate, a lower vertical plate, and a lower horizontal plate, increasing the bonding force with the concrete support to meet the requirements of load anchoring; it is easy to manufacture and install, and the fall arrestor can be made as a single piece or by welding two right-angle plates together; it can also be made directly by bending steel plates, which is convenient to process; after the construction plan is determined, the fall arrestor can be mass-produced in the factory; during installation, it only needs to be cast on both sides of the concrete support, and two fall arrestor components can be designed on one side according to the actual situation, and the protection effect can be increased by using four components; the fall arrestor can be mass-produced in the early stage of construction, and construction can be carried out very conveniently after entering the pipeline installation.
