Description

Technical Field

[0001] This utility model relates to the field of concrete construction technology, specifically to a magnetic tube opening rapid formwork lifting device. Background Technology

[0002] During the construction of building floor slabs, holes need to be pre-drilled for vertical pipes to pass through. To facilitate later pipe installation, the diameter of these holes is often larger than the actual pipe diameter. After the pipes are inserted into these holes, a gap of about 2-3 centimeters will remain around them, requiring formwork and concrete pouring. The traditional method involves cutting polyethylene foam boards to the appropriate size and binding them with wire as an outer formwork to fill the gap with concrete. This is not only time-consuming and labor-intensive, but also results in the inability to reuse materials and significant material waste. Furthermore, if the binding is not secure, the foam boards may detach before the concrete hardens. Utility Model Content

[0003] This utility model was made to solve the above-mentioned technical problems. One of its objectives is to provide a magnetic pipe opening quick formwork lifting device that can provide solid and reliable support for concrete construction at the pipe opening and can be reused.

[0004] To achieve the above objectives, this utility model provides a magnetic tube opening quick lifting mold device, comprising: a first template, which is semi-circular in shape, with a first magnet fixedly disposed at both ends of its lower side; a first liner, which is arc-shaped and disposed at the inner arc of the lower side of the first template; a first anti-slip pad, which is fixedly disposed on the inner side wall of the first liner; a second template, which is semi-circular in shape, with a second magnet fixedly disposed at both ends of its lower side that can attract the first magnet; a second liner, which is arc-shaped and disposed at the inner arc of the lower side of the second template; and a second anti-slip pad, which is fixedly disposed on the inner side wall of the second liner; wherein when the first magnet and the second magnet are attracted together, a circular hole is formed between the first template and the second template.

[0005] Preferably, a number of reinforcing ribs are fixedly provided on the side edges of the lower sides of the first template and the second template.

[0006] Preferably, the lower sides of the first template and the second template are provided with grooves formed by reinforcing ribs to accommodate the first magnet or the second magnet.

[0007] Preferably, a plurality of reinforcing ribs are fixedly provided in the middle of the lower side of the first template and the second template.

[0008] Preferably, the first template and the second template are PVC boards; the first liner and the second liner are PVC pipes.

[0009] Preferably, the first template, the first liner and the reinforcing ribs thereon are an integral structure.

[0010] Preferably, the second template, the second liner and the reinforcing ribs thereon are an integral structure.

[0011] Preferably, the diameter of the circular hole formed between the first template and the second template is equal to the diameter of the pipe at the pipe opening to be constructed.

[0012] Preferably, when the first magnet and the second magnet are attracted together, one end of the first liner extends to the bottom of the second template, and one end of the second liner extends to the bottom of the first template.

[0013] Preferably, when the first magnet and the second magnet are attracted together, the first liner and the second liner are spliced ​​together to form a circular tube.

[0014] Based on the above description and practical application, the magnetic pipe opening quick-lifting formwork of this invention uses two semi-circular ring-shaped templates that are magnetically attached together to quickly form a casting mold surrounding the pipe at the pipe opening to be constructed. The arc-shaped liner below the templates and its anti-slip pads further enhance the magnetic attraction, gripping the pipe tightly and increasing friction to prevent the templates from slipping down. This ensures stable support for the concrete during pouring operations at the pipe opening. After pouring and the concrete reaches a certain strength, applying a large lateral force to the two templates or removing the magnets allows the magnetic pipe opening quick-lifting formwork to be removed for easy reuse.

[0027] Unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] This embodiment discloses a magnetic tube opening quick lifting mold device; please refer to [reference needed]. Figures 1 to 4The magnetic pipe opening quick-lifting mold in this embodiment includes a first template 11, a first liner 21, a first anti-slip pad 31, a second template 12, a second liner 22, and a second anti-slip pad 32. Both the first template 11 and the second template 12 are semi-circular rings, and when joined together, they form a circular template, which can serve as a mold for pouring concrete at the pipe opening. A first magnet 41 is fixedly installed at both ends of the lower side of the first template 11, and a second magnet 42 is fixedly installed at both ends of the lower side of the second template 12. The opposite magnetic poles of the first magnet 41 and the second magnet 42 are arranged opposite each other, and when the ends of the two templates are close together, they can be firmly joined together under the action of magnetic attraction.

[0029] Both the first liner tube 21 and the second liner tube 22 are arc-shaped. For example, a circular tube can be cut along its longitudinal center to form the first liner tube 21 and the second liner tube 22. The first liner tube 21 is located at the inner arc of the lower side of the first template 11, and the second liner tube 22 is located at the inner arc of the lower side of the second template 12. A first anti-slip pad 31 is fixedly installed on the inner wall of the first liner tube 21, and a second anti-slip pad 32 is fixedly installed on the inner wall of the second liner tube 22. When the first template 11 and the second template 12 are joined together, the first liner tube 21 and the second liner tube 22 can be joined to form a circular tube. Figure 4 When the first magnet 41 and the second magnet 42 are attracted together, a circular hole is formed between the first template 11 and the second template 12, allowing the pipe 6 in the building to pass through. The first liner 21 and the second liner 22 can grip the pipe 6, and the friction between the anti-slip pad and the pipe 6 improves its stability, preventing the entire magnetic pipe opening quick-lifting formwork from sliding down.

[0030] This magnetic pipe opening quick-lifting formwork uses magnets to magnetically attach two semi-circular templates together, quickly forming a casting mold around the pipe at the point of construction. An arc-shaped liner beneath the templates, along with its anti-slip pads, magnetically grips the pipe, increasing friction and preventing the templates from slipping. This ensures stable support for the concrete during pouring. After pouring and the concrete reaching sufficient strength, the formwork can be removed by applying a large lateral force to the templates or by removing the magnets, allowing for easy reuse.

[0031] Furthermore, in this embodiment, a plurality of reinforcing ribs 5 are fixedly provided on the side edges of the lower surfaces of the first template 11 and the second template 12. These reinforcing ribs 5 can increase the overall rigidity of the first template 11 and the second template 12, preventing the templates from deforming and affecting the quality of concrete forming.

[0032] Furthermore, in this embodiment, the lower surfaces of the first template 11 and the second template 12 are provided with grooves formed by reinforcing ribs 5 to accommodate the first magnet 41 or the second magnet 42. The first magnet 41 and the second magnet 42 can be engaged in the grooves or fastened in the grooves by bolts. This structural form facilitates the installation and removal of each magnet during use, thereby facilitating the assembly and disassembly of the entire magnetic tube quick-lifting mold device during use. In other embodiments, the first magnet 41 and the second magnet 42 can also be directly fixedly connected to the first template 11 and the second template 12 respectively, for example, by adhesive or bolting to achieve the connection between the template and the magnet.

[0033] Furthermore, in this embodiment, a plurality of reinforcing ribs 5 are fixedly provided in the middle of the lower side surfaces of the first template 11 and the second template 12. These reinforcing ribs 5 can further increase the overall rigidity of the first template 11 and the second template 12, preventing the templates from deforming and affecting the quality of concrete forming.

[0034] In this embodiment, the first template 11 and the second template 12 are PVC boards, and the first liner 21 and the second liner 22 are PVC pipes. Both the templates and the liners are lightweight, facilitating processing, manufacturing, carrying, installation, and use. Furthermore, in this embodiment, the first template 11, the first liner 21, and the reinforcing ribs 5 thereon are all integrally formed, as are the second template 12, the second liner 22, and the reinforcing ribs 5 thereon. During manufacturing, they can be directly integrated using injection molding, further reducing the processing and manufacturing cost of this magnetic tube opening quick-lifting mold device while improving manufacturing efficiency.

[0035] It should be noted that the diameter models of pipe 6 on a building are usually not numerous. Therefore, in this embodiment, after the first template 11 and the second template 12 are joined together, the diameter of the circular hole formed in the middle is set to be equal to the diameter of pipe 6 at the pipe opening to be constructed. Accordingly, on the same building, only a small number of different models of this magnetic pipe opening quick-lifting formwork are needed, and the construction work at each pipe opening can be met by reusing them.

[0036] In one embodiment, the first liner 21 and the second liner 22 can also be non-semi-circular, for example, they can be one-third or one-quarter circular arcs. As long as they are circular arcs, their inner surfaces can rest against the pipe 6 at the pipe opening during actual use, and together with the anti-slip pad, they can increase the friction.

[0037] In one embodiment, when the first magnet 41 and the second magnet 42 are attracted together, one end of the first liner 21 extends below the second template 12, and one end of the second liner 22 extends below the first template 11. In this structure, the liner and template are staggered circumferentially during use, meaning that either liner is simultaneously located below both the first template 11 and the second template 12. This improves the stability of the connection between the first template 11 and the second template 12, ensuring that the magnetic tube quick-lifting formwork device provides stable support for the poured concrete. Furthermore, in this embodiment, when the first magnet 41 and the second magnet 42 are attracted together, the first liner 21 and the second liner 22 are joined into a circular tube. During use, this increases the friction between the magnetic tube quick-lifting formwork device and the pipe 6, further improving the stability of the magnetic tube quick-lifting formwork device.

[0038] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
