Description

Technical Field

[0001] This utility model relates to the technical field of construction formwork system accessories, and in particular to a new type of protective sleeve that allows the hanging bracket cone to be reused. Background Technology

[0002] In modern high-rise building construction, advanced formwork systems such as cantilever climbing formwork and hydraulic self-climbing formwork are widely used. These systems achieve layer-by-layer climbing through a system of embedded parts attached to the already poured concrete walls. The hanging cone (also known as the climbing cone) in the embedded part system is a key component connecting the load-bearing bolts to the pre-embedded bolts in the wall. After the frame has climbed, it needs to be removed from the concrete so that it can be reused on new floors.

[0003] In existing construction practices, to prevent the metal cone from sticking directly to the concrete and causing disassembly difficulties, temporary measures such as applying grease, waste engine oil, or wrapping transparent tape on the cone surface are usually adopted.

[0004] However, these methods have obvious drawbacks: First, they are cumbersome to operate, increasing labor costs and preparation time; second, the results are unstable, and the cone often gets stuck in the concrete, requiring hammering or gas cutting, which damages the cone and renders it unusable; in addition, grease and tape contaminate the cone and the construction environment, making subsequent cleaning difficult. Utility Model Content

[0005] The purpose of this utility model is to provide a new type of protective sleeve that allows the hanging cone to be reused, aiming to solve the problems of the existing technology, such as cumbersome operation, increased labor costs and preparation time; secondly, unstable effect, where the cone is often still "seized" by concrete, requiring hammering or gas cutting, which damages the cone and makes it unusable; in addition, grease and tape will contaminate the cone and the construction environment, making subsequent cleaning difficult.

[0006] To achieve the above objectives, this utility model adopts a novel protective sleeve that allows the hanging bracket cone to be reused, comprising a sleeve body, the sleeve body having a conical structure, the inner and outer surfaces of the sleeve body being smooth surfaces, one end of the sleeve body being a large opening end, the other end of the sleeve body being a conical surface, and the large opening end being 5mm lower than the end face of the conical surface, and the wall thickness of the sleeve body being 1mm.

[0007] The sleeve is made of polyurethane material and is integrally molded using an injection molding process.

[0008] The sleeve is made of polyurethane material and is integrally molded using an injection molding process.

[0009] The taper of the sleeve body is consistent with the taper of the bracket body it is adapted to.

[0010] The operating temperature range of the sleeve is -20℃ to +80℃.

[0011] This utility model discloses a novel reusable protective sleeve for hanging bracket cones. This sleeve design replaces the cumbersome processes of applying grease and wrapping tape, requiring only a single "slip-on" action to complete the preparation, significantly improving construction efficiency. The differentiated design of the inner and outer surfaces ensures that the metal cone can be easily and without damage, avoiding damage and scrapping caused by forceful disassembly, and extending the cone's service life. Simultaneously, it reduces the cost of consumables such as grease and tape, lowering construction costs, and avoids oil pollution, making it more environmentally friendly.

[0017] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0018] Please see Figures 1 to 3This utility model provides a novel protective sleeve for reusable hanging bracket cones, comprising a sleeve body 1, wherein the sleeve body 1 is a conical structure, and both the inner and outer surfaces of the sleeve body 1 are smooth. One end of the sleeve body 1 is a large opening end 2, and the other end of the sleeve body 1 is a conical surface 3, wherein the large opening end 2 is 5mm lower than the end face of the conical surface 3, and the wall thickness of the sleeve body 1 is 1mm.

[0019] In this embodiment, the conical structure with smooth inner and outer surfaces allows the protective sleeve to fit tightly against the hanging cone, effectively isolating the cone from the concrete during concrete pouring and preventing adhesion. The design of the large end 2 being slightly lower than the cone surface 3 ensures that the protective sleeve can stably wrap the cone during concrete pouring, while also facilitating subsequent disassembly. The 1mm wall thickness ensures both the strength and elasticity of the protective sleeve, making it easy to put on and take off, thus improving overall construction efficiency and cone recovery rate.

[0020] Furthermore, the sleeve 1 is made of polyurethane material and is integrally molded by injection molding.

[0021] In this embodiment, the protective sleeve is integrally molded using injection molding, which ensures the structural integrity and dimensional accuracy of the protective sleeve, improves the durability and reliability of the product, reduces manufacturing costs, and the polyurethane material is environmentally friendly and non-toxic, meeting the requirements of green construction.

[0022] Furthermore, the inner diameter of the sleeve 1 in its natural state matches the outer diameter of the bracket cone it is adapted to.

[0023] In this embodiment, the design of the inner diameter of the sleeve fitting the outer diameter of the bracket cone in its natural state ensures that the protective sleeve can tightly wrap around the cone when it is put on, and it is not easy to loosen or slip off. It remains stable during the concrete pouring process, thereby effectively isolating the cone from the concrete and ensuring that the cone can be easily and without damage after pouring.

[0024] Furthermore, the taper of the sleeve 1 is consistent with the taper of the bracket cone it is adapted to.

[0025] In this embodiment, the design of the tapered body 1 matching the tapered body of the bracket ensures a perfect match between the protective sleeve and the cone. This not only improves the convenience and stability of installation, but also ensures that the protective sleeve can be evenly stressed during concrete pouring and disassembly, avoiding disassembly difficulties or cone damage caused by tapered mismatch, thus improving construction efficiency and cone recycling rate.

[0026] Furthermore, the operating temperature range of the sleeve 1 is -20℃ to +80℃.

[0027] In this embodiment, the design of the working temperature range of -20℃ to +80℃ enables the protective cover to adapt to various harsh construction environments, maintaining its elasticity and stability in both cold winters and hot summers.

[0028] In this utility model, construction workers need to take one of the aforementioned sleeves 1 (a polyurethane protective sleeve with a conical structure, smooth inner and outer surfaces, a wall thickness of 1mm, and an inner diameter that fits the outer diameter of the hanging frame cone in its natural state), and tightly fit it onto the outside of the metal hanging frame cone 5, ensuring that it fits to the bottom and the surface is flat. At this time, the large end 2 of the sleeve 1 is slightly lower than the end face 3 of the cone by about 5mm, ensuring a stable wrapping. Next, the cone with the protective sleeve fitted is assembled with other components such as the load-bearing bolt 4, the pre-embedded screw 6, and the embedded plate 7 to form a complete pre-embedded component system, and fixed in the predetermined position of the template. Then, the wall concrete is poured. During the process, the protective sleeve effectively isolates the metal cone from the concrete. When the concrete reaches a certain strength and the climbing frame system needs to climb, the construction workers use special tools to easily unscrew and pull out the metal hanging frame cone 5 from the protective sleeve, completing the recycling. The protective sleeve is left in the concrete wall as a consumable part. At this time, the remaining conical hole can be filled with cement mortar.

[0029] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
