Description

Technical Field

[0001] This utility model relates to the field of pipeline construction technology, specifically to a tail gas pipeline support device. Background Technology

[0002] In industries such as fine chemicals, it is often necessary to install large-diameter exhaust gas pipelines between two buildings. Traditional construction methods require precisely marking the pipeline centerline and the installation positions of all supports on both building facades. Based on the marked positions, embedded parts or post-installed anchors are then installed on the building structure. Main load-bearing supports (such as brackets and triangular braces) and sliding / fixed supports are installed. It is crucial to ensure that all supports are securely installed and that their elevation and spacing are accurate. Double-row external wall scaffolding or a suspended platform for high-altitude operations is also required. The pipe section is then smoothly hoisted to the installation height, guided by high-altitude workers to position it on temporary or pre-installed supports, and temporarily secured. Traditional construction methods often suffer from long construction periods, high costs, and difficulties in guaranteeing safety. Therefore, there is an urgent need for a low-cost, fast, and reliable installation method. Utility Model Content

[0007] In some specific implementation schemes, the steel structure support is provided with fixing holes corresponding to the number of steel wire ropes for fixing the steel wire ropes, and multiple layers of protective rubber tubes are installed in the fixing holes.

[0008] In some specific implementation schemes, the two ends of the wire rope are fixed in the fixing holes by a return method and secured with wedge rope clamps.

[0009] In some specific implementation plans, the steel structure support adopts H-shaped steel supports, and the two ends of the H-shaped steel supports are firmly anchored to the reinforced concrete parapet wall and the floor slab by expansion bolts.

[0026] The present invention will now be described in detail with reference to the accompanying drawings and embodiments:

[0027] Example 1:

[0028] like Figures 1 to 4As shown, this embodiment provides a support device for an exhaust gas pipeline 4, including a pipeline support assembly 1 fixed between two buildings 3 for erecting the exhaust gas pipeline 4, and a bracket fixing assembly 2 fixed on the two buildings 3 for fixing the pipeline support assembly 1. The pipeline support assembly 1 includes a plurality of steel wire ropes 11 and support frames 12 spaced apart on the steel wire ropes 11 for the steel wire ropes 11 to pass through and be positioned. The two ends of the steel wire ropes 11 are respectively fixed on the bracket fixing assemblies 2 of the two buildings 3.

[0029] Specifically, such as Figure 2 As shown, the support fixing assembly 2 includes a steel structure support 21. One end of the steel structure support 21 is fixed to the reinforced concrete parapet wall 31 on the building 3, and the other end is fixed to the floor slab 32. The steel structure support 21, the reinforced concrete parapet wall 31, and the floor slab 32 are fixed in a triangular support structure. The steel structure support 21 is an H-shaped steel support, and both ends of the H-shaped steel support are firmly anchored to the reinforced concrete parapet wall 31 and the floor slab 32 by expansion bolts.

[0030] Specifically, this embodiment uses seven stainless steel-coated wire ropes 11 (the diameter of the wire ropes 11 is φ16 304 stainless steel). Correspondingly, seven fixing holes (7 φ20 holes drilled at designated locations on the support frame) are provided on the steel structure support 21 to secure the wire ropes 11. Multiple layers of protective rubber tubing are installed in the fixing holes to prevent wear between the wire ropes 11 and the holes. Where the seven φ16 304 stainless steel-coated wire ropes 11 pass through the H-shaped steel support, φ25×3 multi-layer rubber tubing is used for protection to prevent wear. When the wire ropes 11 are fixed in the holes, both ends of the wire ropes 11 are fixed using a "return" method and secured with wedge-shaped rope clamps to ensure a safe and reliable connection.

[0031] like Figure 3 As shown, several support frames 12 are evenly spaced in the middle area of ​​several steel wire ropes 11 between the two buildings 3, and each support frame 12 is a U-shaped support frame 12. Specifically, U-shaped support frames 12 with a spacing of 1m can be made of 304 stainless steel angle steel for the passage and positioning of the steel wire ropes 11. In order to enhance the overall rigidity and stability of the steel wire rope 11 bridge, the pipe support assembly 1 also includes several fixing reinforcement members 15. The fixing reinforcement members 15 are made of stainless steel flat steel in the shape of a door arch, and the two ends of the fixing reinforcement members 15 are respectively fixed on the support frame 12. Several fixing reinforcement members 15 are fixed at intervals within several support frames 12. More specifically, a 50×5 stainless steel flat steel is set every 2 meters in the steel wire rope 11 to enhance the overall rigidity and stability.

[0032] like Figure 4As shown, seven wire rope clamps 13 are fixed along the outer wall of the U-shaped support frame 12. Each wire rope clamp 13 has a through hole 14 for the steel wire rope to pass through. Each wire rope clamp 13 includes a U-bolt, the two ends of which are fixed to the stainless steel plate of the U-shaped support frame 12 by nuts. The seven wire rope clamps 13 are symmetrically arranged on the U-shaped support frame 12 to balance the forces on both sides of the pipe.

[0033] The usage process of this embodiment is as follows:

[0034] A φ1200mm stainless steel exhaust gas pipeline is to be installed between two buildings in the fine chemical plant area (assuming the roof elevation of Building A is +25.90m and the roof elevation of Building B is +24.30m, with a distance of approximately 20m). The steps for construction using the exhaust gas pipeline support device proposed in this application are as follows:

[0035] Using the existing reinforced concrete parapet walls on the rooftops of Buildings A and B as supporting foundations, H-shaped steel brackets were fabricated and installed. The H-shaped steel brackets were placed against the parapet walls and together with the parapet walls and floor slabs to form a triangular structure. The H-shaped steel brackets were then firmly anchored to the parapet walls and floor slabs using expansion bolts.

[0036] Before construction, the assembly and welding of the φ1200×1.5 stainless steel exhaust pipes were completed on the ground. Then, seven 304 stainless steel plastic-coated wire ropes were pre-assembled with U-shaped angle steel support frames to form the bridge structure. Two cranes were used in tandem to hoist the entire bridge to the design elevation. The two ends of the wire ropes were passed through φ20 holes on the H-shaped steel supports, then "returned" and secured with wedge-shaped rope clamps. During tensioning, the sag of the wire ropes had to be strictly controlled to ensure it did not exceed 100mm. The multiple layers of rubber tubing within the plastic coating effectively enhance the corrosion resistance and wear resistance of the wire ropes, extending their service life.

[0037] As a reliable support structure, the wire rope bridge can effectively bear the weight of the pipeline and external wind loads, ensuring the long-term stable operation of the pipeline. Calculations show that the breaking tensile force of a single wire rope is 31.15 kN, and the total load-bearing capacity of seven wire ropes is approximately 217 kN (about 22.1 tons). The total weight of the bridge is approximately 9 tons. The wind load, based on a 50-year return period gale of 1.84 kN / m, and the windward length of the pipeline being 25 meters, amounts to a total wind load of approximately 4.6 tons, far less than the load-bearing capacity of the wire rope bridge, indicating a safe and reliable structure. The use of 304 stainless steel plastic-coated wire ropes and U-shaped support frames further enhances the structure's durability and environmental adaptability. This significantly improves construction efficiency, shortens the construction period, and reduces overall costs.

[0038] It is understood that the above embodiments are merely exemplary implementations used to illustrate the principles of this utility model, and the utility model is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of this utility model, and these modifications and improvements are also considered to be within the protection scope of this utility model.
