Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a concrete embedded pipe fixing device. Background Art

[0002] When pre-buried wire pipes are poured in concrete, the conventional method is to use templates to make holes, insert pipes, wrap with tape, excavate later, and smooth and repair the mortar surface. The conventional method has the following problems:

[0003] 1. The on-site hole-drilling method of the template requires high manual operation, and the hole-drilling accuracy is greatly affected by the template quality and drilling tools. In addition, the drill head heats up after a long period of work, as well as operator operation problems, can easily cause the template to crack. At the same time, the current project schedule is tight and the design cycle is short, so there are often drawings to be modified and holes to be adjusted. The template may need to be drilled multiple times, which is prone to leakage and quality risks.

[0004] 2. The method of opening holes in the template and passing pipes has high requirements for demolding. Due to the large size of the template, it is difficult to ensure that the template is perpendicular to the pipeline when demolding. If the on-site pipeline is forgotten to be cut off in time, the embedded pipeline is easy to break when demolding, and the subsequent interface processing is difficult, which is easy to cause quality risks such as leakage.

[0005] 3. When wrapping pipelines with tape on site, it is easy to cause point misalignment due to problems with concrete vibration and the completion of the binding.

[0006] 4. Excavation and repair is not applicable to projects that require one-time forming, such as plain concrete, which limits the scope of application of pre-buried wire pipe installation.

[0007] Therefore, it is necessary to provide a concrete embedded pipe fixing device that can solve the above problems. Summary of the invention

[0008] The utility model aims to provide a concrete pre-buried pipe fixing device which can solve the above-mentioned problem.

[0009] The utility model is achieved in this way:

[0010] A concrete pre-buried pipe fixing device comprises a pre-buried pipe fixing joint, a connecting piece and a template; the diameter of the pre-buried pipe fixing joint is consistent with the inner diameter of the pre-buried pipe, so that one end of the pre-buried pipe fixing joint is matched and inserted into the pre-buried pipe, and the other end of the pre-buried pipe fixing joint is fitted on the inner wall of the template and fixedly connected to the template through the connecting piece, so that the template and the pre-buried pipe are connected into a whole.

[0011] A guide joint is formed at one end of the embedded pipe fixing joint. The guide joint is in a truncated cone structure, and the diameter of the guide joint gradually decreases in the direction away from the template.

[0012] The diameter of the end of the guide joint away from the template is 0.8 times the diameter of the embedded pipe fixed joint.

[0013] The length of the guide joint is 0.5 times the diameter of the embedded pipe fixed joint.

[0014] A flange is formed at the edge of one end of the embedded pipe fixing joint which is fitted with the template. The cross section of the flange is an L-shaped structure, so that the end of the embedded pipe is clamped in the flange.

[0015] The horizontal section length of the flange is equal to the wall thickness of the embedded pipe, so that the inner wall of the embedded pipe is pressed tightly against the outer wall of the embedded pipe fixing joint, and the vertical section inner wall of the flange is pressed tightly against the outer wall of the embedded pipe.

[0016] The flange, the embedded pipe fixing joint and the guide joint are an integrated structure.

[0017] The length of the embedded pipe fixing joint is equal to the diameter of the embedded pipe fixing joint.

[0018] Compared with the prior art, the utility model has the following beneficial effects:

[0019] 1. The utility model is provided with a pre-buried pipe fixing joint and a connecting piece. The pre-buried pipe fixing joint is inserted into the end of the pre-buried pipe and then connected and fixed to the template through the connecting piece. There is no need to pre-drill a hole on the template, which not only simplifies the construction process and ensures the construction efficiency and service life of the template, but also ensures the accurate connection position and connection reliability of the pre-buried pipe and the template, and will not be offset or misaligned during the concrete pouring and vibration process.

[0020] 2. The utility model is provided with embedded pipe fixing joints and connectors, and the embedded pipe fixing joints are tightly fitted to the template with a small gap, thus avoiding the risk of leakage. No tape binding is required, and no subsequent grooving and repair is required. The utility model can be applied to projects that require one-time forming, such as plain concrete, and has a wider range of applications.

[0021] 3. The utility model has a simple structure, and the embedded pipe fixing joint can be customized according to the specifications of the embedded pipe. It is easy to install and easy to remove the mold. It can simplify the construction process of the concrete embedded pipe, which is beneficial to improving the construction efficiency and construction quality, and avoids damage to the template by opening holes.

[0026] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0027] Please see attached Figure 1 To Attachment Figure 3 A concrete embedded pipe fixing device comprises an embedded pipe fixing joint 1, a connecting piece 2 and a template 3; the diameter of the embedded pipe fixing joint 1 is consistent with the inner diameter of the embedded pipe 4, so that one end of the embedded pipe fixing joint 1 is matched and inserted into the embedded pipe 4, and the other end of the embedded pipe fixing joint 1 is fitted on the inner wall of the template 3 and fixedly connected to the template 3 through the connecting piece 2, so that the template 3 and the embedded pipe 4 are connected into a whole.

[0028] After the embedded pipe 4 is laid out, one end of the embedded pipe fixing joint 1 is first inserted into the embedded pipe 4. When installing the template 3, the template 3 is attached to the other end of the embedded pipe fixing joint 1 and fixed by the connecting piece 2, so that the embedded pipe 4 and the template 3 are connected into a whole. There is no need to pre-drill a hole in the template 3, and the accurate positioning of the embedded pipe 4 can be ensured.

[0029] Preferably, the size of the embedded pipe fixing joint 1 is customized according to the size of the embedded pipe 4. The embedded pipe fixing joint 1 can be made of PU material, which has a certain plasticity and is resistant to high temperatures. It will not produce excessive deformation due to the heat of concrete hydration, and the PU material does not adhere to the pipe concrete, making it easy to demold when the template 3 is subsequently disassembled.

[0030] Preferably, the connector 2 can be a self-tapping screw to ensure the reliable connection between the template 3 and the embedded pipe fixing joint 1, prevent it from falling off during concrete pouring and vibration, and ensure the close fit between the template 3 and the embedded pipe fixing joint 1 to prevent concrete leakage. The self-tapping screw can slightly expand the embedded pipe fixing joint 1 when screwed in, making the insertion between the embedded pipe fixing joint 1 and the embedded pipe 4 more secure.

[0031] Please see attached Figure 1 To Attachment Figure 3 A guide joint 101 is formed at one end of the embedded pipe fixing joint 1. The guide joint 101 is in a truncated cone structure, and the diameter of the guide joint 101 gradually decreases in the direction away from the template 3.

[0032] By providing the guide joint 101 of the truncated cone structure, the inclined surface is used to play a guiding role, which facilitates the plugging and connection between the embedded pipe fixed joint 1 and the embedded pipe 4, and the operation is more convenient.

[0033] The diameter of the end of the guide joint 101 away from the template 3 is 0.8 times the diameter of the embedded pipe fixing joint 1.

[0034] The diameter of the small head end of the guide joint 101 can also be adaptively adjusted according to actual use requirements.

[0035] The length of the guide joint 101 is 0.5 times the diameter of the embedded pipe fixed joint 1 .

[0036] The length of the guide joint 101 can be adaptively adjusted according to the guidance and connection requirements.

[0037] Please see attached Figure 1 To Attachment Figure 3 A flange 102 is formed at the edge of one end where the embedded pipe fixing joint 1 is fitted and connected to the template 3. The cross-section of the flange 102 is an L-shaped structure, so that the end of the embedded pipe 4 is clamped in the flange 102.

[0038] By setting the flange 102, the area of ​​the end of the embedded pipe fixing joint 1 can be increased, so that it can fit more reliably with the template 3, and at the same time it is convenient to limit the end of the embedded pipe 4, further improving the connection reliability between the embedded pipe 4 and the template 3.

[0039] The horizontal section length of the flange 102 is equal to the wall thickness of the embedded pipe 4 , so that the inner wall of the embedded pipe 4 is pressed tightly against the outer wall of the embedded pipe fixing joint 1 , and the vertical section inner wall of the flange 102 is pressed tightly against the outer wall of the embedded pipe 4 .

[0040] The flange 102 clamps the end of the embedded pipe 4 to ensure that the embedded pipe fixing joint 1 is inserted into the embedded pipe 4 and will not fall off during the concrete pouring and vibration process.

[0041] The length of the embedded pipe fixing joint 1 is equal to the diameter of the embedded pipe fixing joint 1 .

[0042] The size of the embedded pipe fixing joint 1 can be adaptively adjusted according to actual plug-in requirements.

[0043] The flange 102 is an integral structure with the embedded pipe fixing joint 1 and the guide joint 101 .

[0044] The embedded pipe fixing joint 1 and its guide joint 101 and flange 102 can be manufactured by integrally forming with a mold, and have high structural strength, are not easily damaged, and have a long service life.

[0045] Please see attached Figure 1 To Attachment Figure 3 , the installation method of the utility model is:

[0046] The cylindrical pre-buried pipe fixing joint 1 can be made of PU material, the diameter of the pre-buried pipe fixing joint 1 is made according to the inner diameter of the pre-buried pipe 4, and the horizontal section length of the flange 102 of the pre-buried pipe fixing joint 1 is made according to the wall thickness of the pre-buried pipe 4. The guide joint 101 and the flange 102 can be integrally formed with the pre-buried pipe fixing joint 1.

[0047] After laying out the embedded pipe 4 according to the construction drawings, one end of the embedded pipe fixing joint 1 is inserted into the end of the embedded pipe 4 through the guide joint 101, and the end edge of the embedded pipe 4 is matched and clamped in the flange 102. The template 3 is installed using conventional procedures, and the other end of the embedded pipe fixing joint 1 is fitted with the template 3, and then the template 3 is connected and fixed with the embedded pipe fixing joint 1 through the connector 2, so that the embedded pipe 4 and the template 3 are connected as a whole.

[0048] After the connector 2 is installed, the embedded pipe fixing joint 1 is slightly expanded, and the embedded pipe fixing joint 1 and the embedded pipe 4 are tightened to ensure reliable connection between the embedded pipe fixing joint 1 and the embedded pipe 4, and then concrete pouring and vibration construction can be carried out.

[0049] When the template 3 is disassembled, the embedded pipe fixing joint 1 is disassembled synchronously with the template 3 , and the embedded pipe fixing joint 1 can be removed from the template 3 after the connecting piece 2 is disassembled.

[0050] The above are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
