Description

Technical Field

[0001] The utility model belongs to the technical field of pre-reservation and pre-embedding, and in particular relates to a pre-embedded wire tube fixing device based on an aluminum alloy template. Background Art

[0002] A common practice for pre-embedded wire pipes in various types of buildings is to directly drill holes in the formwork, and the wire pipes pass directly through the holes. The diameter of the holes is larger than the diameter of the wire pipes. Drilling holes in locations where wire pipes are densely packed will create a larger hole in the formwork, which will not only cause permanent damage to the formwork, reduce the rigidity of the formwork, and even destroy the formwork. If the sealing is not tight, it will affect the quality of the concrete components. In addition, after the formwork is removed, the ends of the wire pipes will be exposed. In the subsequent construction process, the ends of the wire pipes will inevitably be damaged, which makes it more difficult to protect the finished products of the wire pipes.

[0003] Another common practice is to add a fixing block on the inside of the formwork and fix it to the formwork with nails, and then put the wire tube on the fixing block to fix the wire tube. In this way, the wire tube will be embedded in the concrete after the formwork is removed, thereby solving the related problems. However, this method will cause the wire tube to be not firmly fixed, and there is a high probability of damage to the fixing block and the formwork after the civil engineering formwork is removed, and it is not suitable for aluminum formwork or steel formwork.

[0004] Chinese patent CN218541525U "A pre-buried pipeline device without opening holes in an aluminum mold" discloses that the pre-buried wire tube is placed on a conical fixing piece fixed on the template to achieve a fixing effect. However, this method has a small contact surface between the wire tube and the fixing piece, which may cause the pre-buried wire tube to fall due to poor fixing. In addition, the pre-buried wire tube cannot extend to the template surface, which may cause the wire tube to be exposed too short, making it difficult to connect the wire tube. In addition, the fixing piece is embedded too deep, resulting in an unstable overall structure of the fixing piece, which may also have a certain impact on the concrete component.

[0005] In order to solve the above problems in the prior art, the purpose of the utility model is to provide a pre-buried wire tube fixing device based on an aluminum alloy template.

[0006] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is a pre-buried wire tube fixing device based on an aluminum alloy template, comprising a template and a conical connecting sleeve, the upper end of the conical connecting sleeve is open, a blind hole is provided on the inner side of the bottom of the conical connecting sleeve, a groove is provided on the inner side of the upper end side wall of the conical connecting sleeve, a sealing ring is installed in the groove, the pre-buried wire tube passes through the sealing ring and the bottom end is installed in the blind hole of the conical connecting sleeve; a bolt hole is provided at the bottom of the conical connecting sleeve, the template is located below the conical connecting sleeve, a fixing bolt is installed in the bolt hole, and the conical connecting sleeve and the template are fixed together by the fixing bolt and the fixing nut.

[0008] Preferably, the diameter of the blind hole is the same as the outer diameter of the pre-buried wire tube, and the pre-buried wire tube is placed in the blind hole to ensure that the pre-buried wire tube does not tilt.

[0009] Preferably, the inner diameter of the sealing ring is slightly smaller than the outer diameter of the pre-buried wire pipe; the sealing ring is used to seal the pre-buried wire pipe and the tapered connecting sleeve to prevent mortar from entering the interior of the device.

[0013] The technical solution of the utility model is further described below in conjunction with specific embodiments, but the protection scope of the utility model is not limited thereto.

[0014] Example 1

[0015] like Figure 1 As shown, a pre-buried wire tube fixing device based on an aluminum alloy template includes a template 5 and a conical connecting sleeve 1, the upper end of the conical connecting sleeve 1 is open, a blind hole is provided on the inner side of the bottom of the conical connecting sleeve 1, a groove is provided on the inner side of the upper end side wall of the conical connecting sleeve 1, a sealing ring 4 is installed in the groove, the pre-buried wire tube 6 passes through the sealing ring 4 and the bottom end of the pre-buried wire tube 6 is installed in the blind hole of the conical connecting sleeve 1; a bolt hole is provided at the bottom of the conical connecting sleeve 1, the template 5 is located below the conical connecting sleeve 1, a fixing bolt 2 is installed in the bolt hole, and a mounting hole is also provided on the template 5, the opening size of the mounting hole is slightly larger than the diameter of the fixing bolt 2, and the conical connecting sleeve 1 and the template 5 are fixed together by the fixing bolt 2 and the fixing nut 3 (the fixing nut 3 is located below the template 5).

[0016] The inner diameter of the sealing ring 4 is slightly smaller than the outer diameter of the embedded wire tube 6. The sealing ring 4 is used to seal the embedded wire tube 6 and the tapered connecting sleeve 1 to prevent mortar from entering the device. When tying the civil engineering steel bars, the tapered connecting sleeve 1 should be avoided so that the tapered connecting sleeve 1 is between the steel bars.

[0017] The diameter of the blind hole is the same as the outer diameter of the pre-buried wire tube 6 , and the pre-buried wire tube 6 is placed in the blind hole to ensure that the pre-buried wire tube 6 does not tilt.

[0018] When in use, the mold release agent is applied to the surface of the template 5 and the conical connecting sleeve 1, and then concrete is poured. After the concrete pouring reaches the strength, the fixing nut 3 is withdrawn before the civil construction template 5 is removed, and then the template 5 is removed; after the template 5 is removed, the conical connecting sleeve 1 and the fixing bolt 2 are removed together. The removed parts can be reused after being reassembled.
