Description

Technical Field

[0001] The utility model relates to the technical field of keels, in particular to a rust-proof light steel keel. Background Art

[0002] Lightweight steel keel is a metal skeleton material used in construction, mainly made of continuous hot-dip galvanized steel strip rolled by cold bending process. It has the characteristics of light weight, easy installation, fast construction, and stable structure, so it is widely used in the frame structure of indoor ceilings and non-load-bearing walls of buildings. The cross-section of lightweight steel keel is diverse, the most common ones are U-shaped, C-shaped, and square-shaped, all of which should comply with the provisions of the national standard GB / T 11981 for lightweight steel keel.

[0003] Among them, for the U-shaped light steel keel, most of them are formed into a U-shaped structure with a notch by cold bending and pressing the plate for many times, and then through welding technology, such as butt welding, the U-shaped plates on both sides of the notch can be welded together to form a complete and U-shaped light steel keel. However, the light steel keel obtained by this process has a larger cross-sectional opening, and the position of the welding notch only occupies a very small part of it. Therefore, when the entire light steel keel is subjected to force, the weld at the notch will bear the main force, which makes it easier for the position to break.

[0004] Therefore, a rust-proof light steel keel is proposed to solve or alleviate the above problems. Utility Model Content

[0005] The utility model aims to solve the shortcomings in the prior art and proposes a rust-proof light steel keel.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A rust-proof light steel keel comprises a keel body, wherein the keel body comprises an outer hollow keel circle and an inner hollow keel circle fixedly connected thereto, wherein the cross-sections of the outer hollow keel circle and the inner hollow keel circle are both in the shape of a square, and the outer hollow keel circle and the inner hollow keel circle are both welded by a plurality of hollow keels, and the cross-section of the hollow keel is a regular hexagon.

[0008] Preferably, a plurality of accommodating grooves located at the inner corners of the outer hollow keel circle are formed between the outer hollow keel circle and the inner hollow keel circle.

[0009] Preferably, a round tube keel is arranged in the accommodating groove, and the outer peripheral wall of the round tube keel is fixedly connected to the outer hollow keel circle and the inner hollow keel circle.

[0010] Preferably, the outer ring and the inner ring of the keel body are both provided with a blue-white zinc-plated layer.

[0011] Preferably, both the outer ring and the inner ring of the keel body are provided with an anti-corrosion coating located outside the blue-white zinc-plated layer.

[0013] Preferably, the anti-corrosion coating is an epoxy resin coating, and the waterproof membrane is a HDPE membrane.

[0014] The utility model has the following beneficial effects:

[0015] The surface of the keel of the utility model has been carefully designed and covered with a blue-white zinc-plated layer, an anti-corrosion coating and a waterproof film in sequence. The superposition of these layers not only significantly improves the waterproof and anti-corrosion performance, but also significantly extends the service life of the keel. In addition, the structure of the keel is composed of evenly welded regular hexagonal hollow keels. This design can achieve uniform dispersion of force when subjected to force. Its unique square shape and regular hexagonal structure further enhance the overall anti-bending performance. In particular, at each inner corner of the keel, a receiving groove is cleverly set and a round tube keel is embedded. This innovation significantly improves the structural strength of these key parts, effectively prevents deformation, and ensures the stability and durability of the entire structure.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] A rust-proof light steel keel, such as Figure 1 and 2As shown, it includes a keel body 1, which includes an outer hollow keel circle 2 and an inner hollow keel circle 3 fixedly connected thereto, the cross-sections of the outer hollow keel circle 2 and the inner hollow keel circle 3 are both in the shape of a U, and the outer hollow keel circle 2 and the inner hollow keel circle 3 are both welded by a number of hollow keels, and the cross-section of the hollow keel is a regular hexagon.

[0022] A plurality of receiving grooves 4 are formed between the outer hollow keel circle 2 and the inner hollow keel circle 3 at the inner corners of the outer hollow keel circle 2 . Circular tube keels 5 are arranged in the receiving grooves 4 . The outer peripheral wall of the circular tube keel 5 is fixedly connected to the outer hollow keel circle 2 and the inner hollow keel circle 3 .

[0023] like Figure 3 As shown, the outer ring and the inner ring of the keel body 1 are both provided with a blue-white zinc-plated layer 6, the outer ring and the inner ring of the keel body 1 are both provided with an anti-corrosion coating 7 located outside the blue-white zinc-plated layer 6, the outer ring and the inner ring of the keel body 1 are both provided with a waterproof membrane 8 located on the anti-corrosion coating 7, the anti-corrosion coating 7 is an epoxy resin coating, and the waterproof membrane 8 is a HDPE membrane.

[0024] The utility model has a blue-white zinc-plated layer 6, an anti-corrosion coating 7, and a waterproof membrane 8 sequentially arranged on its surface, so that the entire keel has a good waterproof effect, so that even if it encounters a water environment or a humid environment, it can also play a water-insulating effect, thereby preventing the keel from rusting, thereby extending its service life and having a good anti-rust effect. In addition, both the outer hollow keel ring 2 and the inner hollow keel ring 3 are welded by a number of regular hexagonal hollow keels. When they are subjected to force, the force is evenly distributed, and each hollow keel is welded, so there is no There is a situation where the strength is high in some places and low in some places. When the whole keel is bent under force, the whole keel can resist it through its U-shaped structure. In addition, when the force is distributed to each hollow keel, it can also be resisted by the regular hexagonal hollow keel. If the inner corner of the whole keel is subjected to external force and tries to deform, since there is a receiving groove 4 at the inner corner of the keel, and a round tube keel 5 is welded therein, the structural strength of the four inner corners of the keel is far superior to other positions, which makes it more difficult for the whole keel to deform, so that it can maintain its original shape and is not easy to deform.

[0025] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
