Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pipeline butt joint construction, in particular to an auxiliary device for butt joint of construction pipelines. Background Technique
[0002] The bonding butt joint method is a common construction butt joint method for non-metallic engineering pipelines such as plastics. When bonding and butt jointing two parts of pipelines, it is necessary to apply a chemical bonding agent at the interface, and after the chemical bonding agent is cured, the butt joint of the two parts of pipelines is completed.
[0003] What is often inconvenient in the above construction is that some pipelines are thin and there is no interface flange. If the bonding area is too small, no matter how good the bonding agent is, it cannot achieve a firm bonding effect.
[0004] In addition, although some chemical bonding agents have good bonding effects, the curing time is relatively long, which may take dozens of minutes to several hours. Some chemical bonding agents even require more than 24 hours to achieve the final bonding effect. However, the pipeline butt joint is constructed outdoors, and workers cannot stay beside the pipeline throughout the curing period. The uncompletely bonded interface is fragile and is easily damaged by human factors or outdoor natural environmental factors (such as strong wind), resulting in repeated use or bonding hidden dangers. Content of the Utility Model

The area expansion ring is used to be sleeved on the outer surface of the butt joint part of two pipelines and is connected to the outer surface of the butt joint part of the two pipelines in a bonding manner. The first clamping component and the second clamping component are integrally arc-shaped and form a circle after butt joint, and are sleeved on the outer ring of the area expansion ring to apply a pre-tightening force to the area expansion ring. Moreover, the first clamping component and the second clamping component can be reused.

[0009] Preferably, for the above auxiliary device for butt joint of construction pipelines, the clamping hoop is made of PC or ABS material, and the flexible pad is made of EPS material.
[0010] Preferably, for the above-mentioned construction pipeline butt joint auxiliary device, the flexible pad is made of a whole piece of material, or the flexible pad is formed by splicing multiple pieces of material.

[0017] The beneficial effects of the present utility model are as follows:
[0018] For the construction pipeline butt joint auxiliary device of the present utility model, by using the area expansion ring, the bonding area of the two pipelines is extended from the radial interface part to the outer surface, increasing the bonding strength between them. Then, by sleeving the first clamping assembly and the second clamping assembly on the outer ring of the area expansion ring to apply a pre-tightening force, on the one hand, the pre-tightening force can make the bonding surface of the area expansion ring and the pipeline contact more fully, improving the bonding effect; on the other hand, during the process of waiting for the chemical adhesive to completely cure, it plays a certain protective role, especially in the case of unattended operation, it can prevent some external factors from affecting.
[0019] The construction pipeline butt joint auxiliary device of the present utility model has low cost and a simple structure, but solves major problems in pipeline construction. Description of the Drawings

[0024] Figure 4 The figure shows the schematic diagram of the use principle of the construction pipeline docking auxiliary device of the present utility model.
[0025] The components represented by each reference numeral in the figure are:
[0026] The first clamping assembly 10, the first connecting portion 11, the second clamping assembly 20, the second connecting portion 21, the area expansion ring 30, and the pipeline 40. Specific embodiments
[0027] See Figures 1 to 3 , a construction pipeline docking auxiliary device of this embodiment is applied to the bonding docking construction of pipelines, and includes a first clamping assembly 10, a second clamping assembly 20, and an area expansion ring 30.
[0028] Combined with Figure 4 the schematic diagram of the use principle, the above-mentioned area expansion ring 30 is used to sleeved on the outer surface of the docking part of two pipelines 40 and is connected to the outer surface of the docking part of the two pipelines 40 in a bonding manner.
[0029] During construction, some pipelines 40 are relatively thin and there are no interface flanges. If the bonding area is too small, even the best adhesive cannot achieve a firm bonding effect. The first function of the area expansion ring 30 in this embodiment is to expand the bonding area of the two pipelines 40 from the radial interface part to the outer surface to increase the bonding strength between them. Therefore, the area expansion ring 30 is made of an adhesive-friendly material, and materials the same as or similar to those of the pipeline 40 are preferably considered.
[0030] Continue to refer to Figures 1 to 3 , the first clamping assembly 10 and the second clamping assembly 20 are integrally arc-shaped and form a circle after docking, and are sleeved on the outer ring of the area expansion ring 30 to apply a pre-tightening force to the area expansion ring 30.
[0031] Some adhesives used in construction have a relatively long curing time, which may take dozens of minutes to several hours. Some chemical adhesives even require more than 24 hours to achieve the final bonding effect. However, the pipeline docking is carried out outdoors, and workers cannot stay beside the pipeline throughout the entire curing cycle. The uncompletely bonded interface is fragile and vulnerable to being damaged by human factors or outdoor natural environmental factors (such as strong wind), resulting in repeated use or bonding hidden dangers. After bonding the area expansion ring 30 to the outer surface of the docking part of the two pipelines 40, by sleeving the first clamping assembly 10 and the second clamping assembly 20 on the outer ring of the area expansion ring 30 to apply a pre-tightening force to the area expansion ring 30, on the one hand, the pre-tightening force can make the bonding surface of the area expansion ring 30 and the pipeline 40 contact more fully, improving the bonding effect; on the other hand, during the process of waiting for the chemical adhesive to completely cure, it plays a certain protective role, especially in the case of unattended operation, which can prevent some external factors from affecting.
[0032] Obviously, the area expansion ring 30 is bonded to the pipeline 40, which has a permanent reinforcement and protection effect on the pipeline 40, and the first clamping assembly 10 and the second clamping assembly 20 can be reused.
[0033] In order to make it more convenient to manufacture and better achieve the above purposes, the first clamping assembly 10 and the second clamping assembly 20 in this embodiment are both made of multi-layer materials, including an outer clamping hoop and an inner flexible pad. After the first clamping assembly 10 and the second clamping assembly 20 are butted to form a circle, they are fixedly connected through the outer clamping hoop.
[0034] For example, the clamping hoop is made of PC or ABS material, which has the advantages of low cost, waterproof, sunscreen, anti-corrosion, and certain flexible mechanical properties, which is also convenient for construction operation.
[0035] The flexible pad is more prominent in flexibility and elasticity, which is convenient for applying a pre-tightening force to the inner area expansion ring 30. For example, EPS material is preferred. And the flexible pad can be made of a whole piece of material or spliced by multiple pieces of material.
[0036] The following is an example to illustrate the connection and fixing method of the first clamping assembly 10 and the second clamping assembly 20.
[0037] In the example of the drawings, the clamping hoop end of the first clamping assembly 10 has a first connecting portion 11, and the clamping hoop end of the second clamping assembly 20 has a second connecting portion 21. Specifically, the first connecting portion 11 is a through hole opened at the clamping hoop end, and the second connecting portion 21 is a connecting rod provided at the clamping hoop end. The connecting rod can pass through the through hole, and threads are also machined at the end of the connecting rod. After the connecting rod passes through the through hole, the first clamping assembly 10 and the second clamping assembly 20 can be firmly fixed to each other by using a nut that cooperates with the connecting rod.
[0038] As can be seen from the drawings, since the nut is installed outward and the material of the clamping hoop also has a certain elasticity, the installation and disassembly of the above connection structure are very convenient.
[0039] In the drawings of this embodiment, the area expansion ring 30 is shown as a closed circle. In this case, there is a sliding gap between the inner wall of the area expansion ring 30 and the outer wall of the pipeline 40. This sliding gap not only facilitates the sleeving of the area expansion ring 30, but also does not have an obvious impact on the applied chemical binder.
[0040] However, although not shown in the drawings, the present invention does not limit the area expansion ring 30 to be necessarily closed. For more convenient operation, the area expansion ring 30 can be a split arc. Moreover, in some cases, due to the operating conditions of the pipeline 40, it may also be required that the area expansion ring 30 is split.
[0041] Finally, the axial length (i.e., width) of the area expansion ring 30 can be manufactured or intercepted as needed, and generally should be less than or equal to the axial length of the first clamping assembly 10 and the second clamping assembly 20.
[0042] In summary, the present invention uses the area expansion ring 30 to expand the bonding area of the two pipelines 40 from the radial interface part to the outer surface, increasing the bonding strength between them. Then, by sleeving the first clamping assembly 10 and the second clamping assembly 20 on the outer ring of the area expansion ring 30 to apply a pre-tightening force to the area expansion ring 30, on the one hand, the pre-tightening force can make the bonding surface of the area expansion ring 30 and the pipeline 40 contact more fully, improving the bonding effect. On the other hand, during the process of waiting for the chemical binder to completely cure, it plays a certain protective role, especially in the case of unattended operation, it can prevent some external factors from affecting.
[0043] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
