Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a pre-reserved pipeline protection device for aluminum formwork convex boxes that does not require drilling. Background Technology

[0002] The main problem with traditional pre-installation of electromechanical pipelines in building construction is that the electromechanical professionals need to make holes in the formwork at the pipeline outlet, so that the pipeline extends 30-50mm beyond the bottom of the beam or slab. After the formwork is removed, the pipeline is completely exposed outside the structure, which can easily cause damage to the pipeline during later decoration and installation work, causing it to break from the root and making it impossible to extend the pipeline. The only solution is to chisel out the structure.

[0003] Given the drawbacks of the traditional method of pre-embedding electromechanical pipelines, it is essential to develop a pipeline protection device that can conceal the pre-embedded pipelines, prevent damage, and eliminate the need for drilling holes in the aluminum template. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a pre-reserved pipeline protection device for aluminum formwork convex boxes without drilling holes, so that it can form a groove on the surface of the structure after concrete is poured, and the pre-reserved pipeline is hidden in the groove and is not easily damaged. Moreover, there is no need to drill holes in the formwork, which extends the service life of the formwork and improves the turnover rate of the formwork, thereby overcoming the shortcomings of the prior art.

[0005] To solve the above-mentioned technical problems, this utility model provides a pre-reserved pipeline protection device for aluminum mold convex boxes without drilling holes, including a template and a convex box. The convex box is a rectangular empty box with an open top. The top is provided with outward-curved skirts around the four sides. Connection holes are opened at the four corners of the skirts for fixing to the template with screws. A first mounting hole is opened at the center of the bottom of the convex box to allow the conduit to pass through.

[0006] As an improvement of this utility model, the above-mentioned pre-reserved pipeline protection device for aluminum mold protrusion box without drilling also includes a back plate. The back plate is rectangular, and one side surface is provided with an annular protrusion that matches the position, number, and size of the first mounting hole. A second mounting hole is opened along the inner diameter of the annular protrusion, penetrating the back plate. The outer bottom of the protrusion box is provided with a rectangular back plate slot that matches the size of the back plate. The back plate is engaged and fixed in the back plate slot, the annular protrusion is engaged and fixed in the first mounting hole, and the conduit is inserted into the second mounting hole.

[0007] Furthermore, the template and the convex box are made of aluminum alloy.

[0008] With this design, the present invention has at least the following advantages.

[0009] 1. This utility model adds a protruding box to a standard aluminum template and makes a first installation hole on the protruding box according to the size and quantity of the pre-embedded pipeline. After the end of the conduit is inserted into the first installation hole, concrete is poured, thereby forming a groove on the surface of the structure after pouring. The conduit is hidden in the groove and is not easily damaged, which improves the quality of the pre-embedded pipeline and makes the positioning more accurate.

[0010] 2. The protruding box and the template are connected by screws, eliminating the need to drill holes in the standard template, thus extending the service life of the template and improving the turnover rate of the template.

[0011] 3. When the pre-embedded conduit uses a small diameter pipe, a back plate can be installed on the bottom surface of the convex box. The back plate is snapped into the back plate slot by a snap-fit ​​fixing method, and the annular protrusion is snapped into the first mounting hole. At this time, the small diameter conduit can be inserted into the second mounting hole for structural pouring. The back plate, the annular protrusion and the second mounting hole together play the role of reducing the diameter, which is suitable for the construction of small diameter conduits.

[0012] 4. It has a simple structure, is easy to construct, and is suitable for widespread application. Attached Figure Description

[0018] Please see Figure 1 The first embodiment of this utility model provides a pre-reserved pipeline protection device for aluminum mold convex boxes without drilling, including a template 1 and a convex box 2.

[0019] The convex box 2 is a rectangular empty box with an open top. The top is provided with outward-curving skirts 21 around the perimeter. The four corners of the skirts 21 have connecting holes for fixing to the template 1 with screws 3.

[0020] The bottom of the convex box has a first mounting hole 22 for allowing the conduit 5 to pass through. In this embodiment, there is one first mounting hole 22. In other embodiments, the number and size of the first mounting holes 22 need to be determined according to the construction drawings.

[0021] The template 1 and the convex box 2 are made of aluminum alloy.

[0022] During construction, the protruding box 2 is installed on the template 1 using screws 3 according to the design position, and the end of the conduit 5 to be embedded is inserted into the first mounting hole 22, so that the outer wall of the conduit 5 fits tightly with the first mounting hole 22. After assembling the templates, the concrete is poured. After the pouring is completed and the formwork is removed, a groove is formed on the surface of the structure, and the end of the conduit 5 is hidden in the groove, forming a protective layer to prevent damage.

[0023] Please see Figure 2 and Figure 3 In the second embodiment of this utility model, a back plate 4 is also included.

[0024] The back plate 4 is rectangular, and one side surface is provided with an annular protrusion 41 that matches the position, number and size of the first mounting hole 22, and a second mounting hole 42 that penetrates the back plate 4 is opened along the inner diameter of the annular protrusion 41.

[0025] The bottom of the convex box 2 is provided with a rectangular back plate slot 22 that matches the size of the back plate 4. The back plate 4 is engaged and fixed in the back plate slot 22. The annular protrusion 41 is engaged and fixed in the first mounting hole 21. The conduit 5 is inserted into the second mounting hole 42.

[0026] It should be noted that the back plate 4 is an optional component used in the construction of small-diameter conduit 5. During on-site construction, small-diameter conduits may be pre-embedded in certain areas due to construction limitations. In this case, the back plate 4 can be snapped into the back plate slot 22, and the annular protrusion 41 can be inserted into the first mounting hole 22 to reduce the diameter, allowing the small-diameter conduit 5 to be inserted into the second mounting hole 42 and fit tightly, facilitating subsequent structural pouring.

[0027] This utility model has a simple structure and is easy to use. It can effectively protect the pre-buried pipelines, improve construction efficiency and quality, and eliminate the need to drill holes in the template, thus extending the template's service life and increasing its turnover rate.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes or alterations made by those skilled in the art using the above-disclosed technical content shall fall within the protection scope of the present utility model.
