Description

Technical Field

[0001] This utility model belongs to the technical field of anti-pull-out technology for corrugated compensators in building air conditioning systems, and specifically relates to an anti-pull-out structure. Background Technology

[0002] In air conditioning water systems in the building industry, rows of pipes expand and contract due to temperature changes, causing axial, lateral, or angular displacements. To effectively absorb these displacements, release internal stresses, and ensure the safe and stable operation of the system, corrugated compensators are typically installed on the pipes. The corrugated compensators provide reliable flexible compensation for the pipes through their own elastic deformation.

[0003] However, the bellows compensator's own structure and simple support structure alone cannot ensure its safe operation under certain conditions. For example, abnormally high pressure generated during system pressure testing or operation may far exceed the compensation capacity of the bellows compensator and the constraint limits of the support, causing the bellows compensator to pull out, twist, shift, or even be damaged. Summary of the Invention

[0004] This utility model provides an anti-pull-out structure, which realizes the fixation and support of rows of pipes, and at the same time protects the safe operation of the corrugated compensator.

[0005] The technical solution of this utility model is as follows:

[0006] A pull-out prevention structure is used to fix multiple pipes arranged in a first plane. Each pipe is equipped with a corrugated compensator, and each pipe has a first section away from the corrugated compensator and a second section close to the corrugated compensator. The pull-out prevention structure includes:

[0007] A first connecting assembly is used to connect to a beam located below the floor slab or the bottom surface of the floor slab, and to fix the first section of the plurality of pipes;

[0008] The second connecting assembly is used to connect to the beam or the bottom surface of the floor slab located below the floor slab, and to fix the second section of the plurality of pipes.

[0009] Furthermore, in the aforementioned anti-pull-out structure, the first connecting component includes a first connecting beam and two second connecting beams.

One end of each second connecting beam is connected to the first connecting beam, and the other end of each second connecting beam is connected to a beam below the floor slab or a third connecting beam on the beam or the bottom surface of the floor slab.

[0010] Furthermore, in the aforementioned anti-pull-out structure, the first connecting assembly further includes a plurality of connecting pipes inclined relative to the pipe axis. These connecting pipes are used to connect one-to-one with a plurality of pipes. One end of each connecting pipe is connected to a beam below the floor slab, a third connecting beam on the beam, or the bottom surface of the floor slab. The other end of each connecting pipe is provided with an arc-shaped plate, which is used to connect to the top surface of the pipe; and / or,

[0011] The first connecting beam is provided with a plurality of first locking components, which are used to lock the pipe onto the first connecting beam; and / or,

[0012] A fourth connecting beam is vertically arranged between the two second connecting beams.

[0013] Furthermore, in the aforementioned anti-pull-out structure, the first locking assembly includes a clamp, a wooden clamp, and two bolt assemblies. The wooden clamp is sleeved on the pipe, the clamp is used to wrap around the wooden clamp, and the two bolt assemblies are respectively used to lock both ends of the clamp to the first connecting beam; and / or,

[0014] One end of the connecting pipe is connected to the beam below the floor slab or the bottom surface of the floor slab via fasteners, or welded to a third connecting beam on the beam; the other end of the connecting pipe is welded to the top surface of the arc-shaped plate, and the bottom surface of the arc-shaped plate is welded to the pipe; and / or,

[0015] The curved plate is made of metal.

[0016] Furthermore, in the aforementioned anti-pull-out structure, the first connecting beam, the two second connecting beams, and the third connecting beam constitute an integral rectangular frame structure; and / or,

[0017] The pipe is provided with insulation cotton and a protective shell, the insulation cotton is wrapped around the pipe, and the protective shell is fitted over the insulation cotton; and / or,

[0018] The connecting pipe is a seamless steel pipe; and / or,

[0019] The first connecting beam, the second connecting beam, and the third connecting beam are channel steel; and / or,

[0020] The fastener is an expansion bolt.

[0021] Furthermore, in the aforementioned anti-pull-out structure, the second connecting component includes two parallel U-shaped connecting frames and at least one fifth connecting beam. The bottom frames of the two connecting frames are connected by the fifth connecting beam. The bottom frames of the two connecting frames are located below multiple pipes and are used to support multiple pipes. The pipe axis and the plane where the connecting frames are located are perpendicular to each other. The tops of the two connecting frames are respectively used to connect to the floor slab or the beam below the floor slab. The corrugated compensator of the pipe is located between the two connecting frames.

This effectively improves the fixation and support of multiple pipelines in a row, protects the safe operation of the pipelines and bellows compensators, and provides reliable protection for the pipelines and bellows compensators, especially during pressurization or under excessively high pressure, thereby improving safety.

[0028] The first connecting component of this anti-pull-out structure uses a connecting pipe to diagonally pull the pipeline, which not only improves the reinforcement strength of multiple pipelines, but also absorbs the axial force of the pipeline, protecting the corrugated compensator from working within its normal compensation range.

[0029] The second connecting component of the anti-pull-out structure uses two U-shaped connecting frame structures to bear the weight of multiple pipes and clamp the corrugated compensators on multiple pipes, which can prevent the expansion segment from being pulled out and twisted or displaced.

[0030] The anti-pull-out structure uses commonly used construction materials, which not only simplifies the processing and operation but also saves on material costs. Attached Figure Description

[0036] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. The advantages and features of the present invention will become clearer from the following description and claims. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0037] like Figure 1 As shown, this embodiment provides an anti-pull-out structure for fixing multiple pipes 3. The multiple pipes 3 are arranged in a first plane, and the multiple pipes 3 are preferably arranged in parallel and spaced apart. A corrugated compensator 4 is provided on the pipe 3. The pipe 3 has a first section away from the corrugated compensator 4 and a second section close to the corrugated compensator 4. The anti-pull-out structure includes a first connecting component 1 and a second connecting component 2.

[0038] like Figure 1 , Figure 2 and Figure 3 As shown, the first connecting assembly 1 is used to connect to the beam 6 located below the floor slab 5 or the bottom surface of the floor slab 5, and to fix the first section of multiple pipes 3. The first connecting assembly 1 may include a first connecting beam 11 and two second connecting beams 12. The first connecting beam 11 is located below the multiple pipes 3 and is used to support the multiple pipes 3. One end of each second connecting beam 12 is connected to the first connecting beam 11, and the other end of each second connecting beam 12 is connected to the beam 6 below the floor slab 5 or a third connecting beam 13 on the beam 6 or the bottom surface of the floor slab 5. The first connecting beam 11, the second connecting beam 12, and the third connecting beam 13 are preferably channel steel.

[0039] Specifically, one end of each of the two second connecting beams 12 of the first connecting assembly 1 is welded to both ends of the first connecting beam 11, and the other ends of the two second connecting beams 12 are welded to both ends of the third connecting beam 13, forming a rectangular frame structure. Multiple pipes 3 laid in a row pass through the first connecting assembly 1 in their first section. The first connecting beam 11 is located below the multiple pipes 3, providing support. The third connecting beam 13 is installed on the beam 6 located below the floor slab 5 using fasteners 001. This first connecting assembly 1 strengthens the fixation of the row of pipes 3 and protects the corrugated compensator 4 within its normal compensation range.

[0040] like Figure 1 , Figure 2 and Figure 4 As shown, the second connecting component 2 is used to connect to the beam 6 located below the floor slab 5 or the bottom surface of the floor slab 5, and to fix the second section of multiple pipes 3. The second connecting component 2 may include two parallel U-shaped connecting frames 21 and at least one fifth connecting beam 22. The bottom frames of the two connecting frames 21 are connected by the fifth connecting beam 22. The bottom frames of the two connecting frames 21 are located below the multiple pipes 3 and are used to support the multiple pipes 3. The axial direction of the pipes 3 is perpendicular to the plane where the connecting frames 21 are located. The tops of the two connecting frames 21 are respectively used to connect to the floor slab 5 or the beam 6 below the floor slab 5. The corrugated compensator 4 of the pipes 3 is located between the two connecting frames 21.

[0041] Specifically, the bottom frames of the two U-shaped connecting frames 21 are welded together by two or three fifth connecting beams 22 to form an integrated structure. The second section of multiple pipes 3 laid in a row passes through the second connecting assembly 2. The bottom frames of the two U-shaped connecting frames 21 are located below the multiple pipes 3, supporting them. The tops of the two connecting frames 21 are installed on the floor slab 5 using fasteners 001 (e.g., expansion bolts). The corrugated compensators 4 of the multiple pipes 3 are located between the two connecting frames 21, spaced 200mm apart. The second connecting assembly 2 clamps the corrugated compensators 4, preventing the expansion sections of the pipes 3 from pulling off the corrugated compensators 4 and causing twisting or displacement.

[0042] In the above structure, the first connecting component 1 and the second connecting component 2 are combined to form a dual protection mechanism, which effectively improves the fixation and support of multiple pipes 3 in a row, and protects the safe operation of the pipes 3 and the corrugated compensator 4.

[0043] like Figures 1-3As shown, in a preferred embodiment, the first connecting assembly 1 further includes a plurality of connecting pipes 14 arranged obliquely relative to the axial direction of the pipe 3. The connecting pipes 14 are preferably seamless steel pipes. Each of the multiple connecting pipes 14 is used to connect to one of the multiple pipes 3. One end of each connecting pipe 14 is connected to the beam 6 below the floor slab 5, or to the third connecting beam 13 on the beam 6, or to the bottom surface of the floor slab 5. The other end of each connecting pipe 14 is provided with an arc-shaped plate 15, which is used to connect to the top surface of the pipe 3. The third connecting beam 13 is installed on the beam 6 using expansion bolts and is arranged parallel to the first connecting beam 11. The arc-shaped plate 15 is made of metal, such as stainless steel.

[0044] Specifically, after the rectangular frame structure of the first connecting component 1 reinforces the first section of the multiple pipes 3, one end of each of the multiple connecting pipes 14 is sequentially welded to the third connecting beam 13 of the beam body 6 along the laying direction of the pipes 3. Then, arc-shaped plates 15 are welded to the other ends of the multiple connecting pipes 14 respectively. Finally, the bottom surfaces of the multiple arc-shaped plates 15 are welded to the top surfaces of the multiple pipes 3 one by one. The use of diagonal bracing not only absorbs the axial force of the multiple pipes 3, but also, in conjunction with the first connecting beam 11 and the two second connecting beams 12, further improves the fixing strength of the multiple pipes 3.

[0045] like Figure 2 and Figure 3 As shown, furthermore, the first connecting beam 11 is provided with multiple first locking components 16, which are used to lock the pipe 3 onto the first connecting beam 11. The first locking component 16 may include a clamp 161, a wooden clamp 162, and two bolt assemblies 163. The wooden clamp 162 is sleeved on the pipe 3, the clamp 161 is used to wrap around the wooden clamp 162, and the two bolt assemblies 163 are used to lock the two ends of the clamp 161 onto the first connecting beam 11. When multiple connecting pipes 14 provide diagonal bracing for multiple pipes 3 arranged in a row, the wooden clamp 162 of the first locking component 16 is first wrapped around the outer wall of the pipe 3, then the clamp 161 is wrapped around the outer wall of the wooden clamp 162, and finally the two ends of the clamp 161 are locked onto the first connecting beam 11 by the bolt assemblies 163 to reinforce the pipe 3. The first locking component 16 can fix the first section of the pipe 3 to the first connecting beam 11, further improving the reinforcement effect of the pipe 3.

[0046] like Figure 3 As shown, a fourth connecting beam 17 is further vertically arranged between the two second connecting beams 12. One end of the fourth connecting beam 17 is welded to the middle position of the first connecting beam 11, and the other end of the fourth connecting beam 17 is welded to the middle position of the third connecting beam 13. The fourth connecting beam 17 is arranged parallel to the two second connecting beams 12. The arrangement of this fourth connecting beam 17 further improves the reinforcement effect of the multiple pipes 3.

[0047] like Figure 1 As shown, furthermore, one end of the connecting pipe 14 is connected to the beam 6 below the floor slab 5 or the bottom surface of the floor slab 5 via a fastener 001, or is welded to the third connecting beam 13 on the beam 6. The other end of the connecting pipe 14 is welded to the top surface of the arc-shaped plate 15, and the bottom surface of the arc-shaped plate 15 is welded to the pipe 3. The fastener 001 is preferably an expansion bolt. This welding connection method further improves the support and reinforcement strength of the first connecting assembly 1 for the multiple pipes 3 in a row.

[0048] like Figure 3 As shown, in a preferred embodiment, the first connecting beam 11, the two second connecting beams 12, and the third connecting beam 13 form an integral rectangular frame structure. This integral rectangular frame structure improves the reinforcement strength of the multiple pipes 3.

[0049] like Figure 2 As shown, furthermore, the pipe 3 is provided with insulation cotton 164 and a protective shell 165. The insulation cotton 164 wraps around the pipe 3, and the protective shell 165 is fitted over the insulation cotton 164. The insulation cotton 164 and the protective shell 165 work together to provide insulation and protection for the pipe 3.

[0050] like Figure 2 As shown, in a preferred embodiment, a plurality of second locking components 23 are provided on the top of the bottom frames of the two connecting frames 21. The second locking components 23 are used to lock the pipe 3 onto the bottom frames of the connecting frames 21. The structure of the second locking components 23 is the same as that of the first locking components 16, and can also be adjusted as needed. The provision of the second locking components 23 facilitates the fixing of the second section of the pipe 3 onto the bottom frames of the two connecting frames 21.

[0051] like Figure 4 As shown, in a preferred embodiment, the three fifth connecting beams 22 and the two connecting frames 21 are an integral structure. This integral structure of the second connecting assembly 2 significantly enhances the support strength of the multiple pipes 3 and the corrugated compensator 4.

[0052] like Figure 4 As shown, in a preferred embodiment, a connecting plate 24 is provided on the top of the two connecting frames 21. The connecting plate 24 is connected to the floor slab 5 or the beam 6 below the floor slab 5 by a fastener 001. The fastener 001 is preferably an expansion bolt. The provision of the connecting plate 24 and the fastener 001 facilitates the installation of the connecting frame 21 on the floor slab 5 or the beam 6 below the floor slab 5, increasing the reliability of the connection.

[0053] like Figure 4As shown, in a preferred embodiment, a sixth connecting beam 25 is vertically arranged on the bottom frame of the connecting frame 21, transforming the U-shaped connecting frame 21 into a mountain-shaped connecting frame 21. The sixth connecting beam 25 is close to and perpendicular to the fifth connecting beam 22 located in the middle. The arrangement of this sixth connecting beam 25 further enhances the reinforcement strength of the second section of the multiple pipes 3.

[0054] The above description is only a description of the preferred embodiment of the present utility model and is not intended to limit the scope of the present utility model in any way. Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the protection scope of the claims.
