Description

Technical Field

[0001] The utility model relates to the field of light steel keel technology, in particular to a light steel keel with high bending resistance. Background Technique

[0002] Light steel keel is a kind of metal structural material widely used in the construction field. It is formed by cold bending a continuously hot-dip galvanized steel strip into products with different cross-sectional shapes such as U-shaped and C-shaped. This material has the characteristics of light weight, high strength, good corrosion resistance, and convenient construction and installation. Light steel keel is usually used as the skeleton of interior ceiling and non-load-bearing walls in buildings. It is connected with suspender rods to provide installation nodes for the surface facing board, playing a connecting role between the upper and lower. During the construction process, gypsum board or other facing board materials are placed on the light steel keel to complete the decoration, sound insulation, heat insulation and other functions of the ceiling or wall. In addition, the surface treatment process of light steel keel is also very important. Usually, cold rolling method and combined forming method are adopted, which can improve the performance and service life of the product. In modern architecture, the use of light steel keel not only improves the construction efficiency, but also provides more design flexibility and structural safety for the building due to its light weight and good mechanical properties.

[0003] The current light steel keel is essentially formed by cold rolling of plates, that is, it still achieves the existing different cross-sectional shapes such as U-shaped and C-shaped by destroying its original structure. In this way, in terms of its structural strength, it is certainly impossible to compare with the structure that is originally in the shape of U-shaped, C-shaped and other different cross-sections, and to a certain extent, it is also prone to bending.

[0004] Therefore, a light steel keel with high bending resistance is proposed to solve or alleviate the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to solve the deficiencies existing in the prior art, and to propose a light steel keel with high bending resistance.

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

[0007] A light steel keel with high bending resistance, comprising a U-shaped keel frame, a cross-shaped keel frame, and a central keel frame;

[0008] The cross-shaped keel frame is in an X shape, and the cross-shaped keel frame is fixedly connected inside the U-shaped keel frame;

[0009] The central keel frame is fixedly connected to the intersection of the cross-shaped keel frame.

[0010] Preferably, a reinforcing keel is fixedly connected to the back surface of the U-shaped keel frame.

[0011] Preferably, vertical reinforcing plates are fixedly connected to both sides of the U-shaped keel frame.

[0012] Preferably, a horizontal reinforcing plate located between the reinforcing keels is fixedly connected to the back of the U-shaped keel frame.

[0013] Preferably, the U-shaped keel frame, the reinforcing keels, and the cross-shaped keel frame are all welded by a number of sub-keels, and the cross-sections of the sub-keels and the central keel frame are both regular hexagons, and the cross-sectional area of the sub-keel is smaller than that of the central keel frame.

[0014] Preferably, both the sub-keel and the central keel frame include sheet plates and an epoxy resin penetration layer coated on the outside thereof.

[0015] Preferably, a polyurea elastic waterproof layer is coated on the outside of the epoxy resin penetration layer.

[0016] The utility model has the following beneficial effects:

[0017] When the utility model forms a U-shaped structure, it can form the structure through a number of sub-keels, changing the original thin sheet-like structure into a structure with a certain thickness. Since the cross-section of the sub-keel is a regular hexagon and is hollow, it does not excessively increase the weight of the entire keel, and it can also resist through the structure of the sub-keel when the entire keel is forced to deform. Among them, the cross-shaped keel frame will strengthen the structure of the U-shaped keel frame to resist deformation attempts from the outside to the inside or from the inside to the outside. Among them, the central keel frame is used as the main support object to support the cross-shaped keel frame, and when an external force is transmitted through the U-shaped keel frame and the cross-shaped keel frame, it can also be carried by the central keel frame and resist the external force, making it difficult for the entire keel to deform, having high bending resistance. The horizontal reinforcing plate and the vertical reinforcing plate not only provide further structural strength for the entire keel, but also provide a plane for the entire keel during subsequent installation, so that this keel can be in surface contact with other structures. The epoxy resin penetration layer and the polyurea elastic waterproof layer bring good protection performance to the entire keel, making it not easily damaged and having a relatively long service life.

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0023] A light steel keel with high bending resistance, as Figure 1 and 2 shown, includes a U-shaped keel frame 1, a cross-shaped keel frame 3, and a central keel frame 2;

[0024] The cross-shaped keel frame 3 is in an X shape, and the cross-shaped keel frame 3 is fixedly connected inside the U-shaped keel frame 1;

[0025] The central keel frame 2 is fixedly connected to the intersection of the cross-shaped keel frame 3.

[0026] A reinforced keel is fixedly connected to the back of the U-shaped keel frame 1.

[0027] Vertical reinforcement plates 5 are fixedly connected to both sides of the U-shaped keel frame 1, and a horizontal reinforcement plate 6 located between the reinforced keels is fixedly connected to the back of the U-shaped keel frame 1.

[0028] The U-shaped keel frame 1, the reinforced keel, and the cross-shaped keel frame 3 are all welded by a number of sub-keels, and the cross-sections of the sub-keels and the central keel frame 2 are both regular hexagons, and the cross-sectional area of the sub-keel is smaller than the cross-sectional area of the central keel frame 2.

[0029] As Figure 3 shown, both the sub-keel and the central keel frame 2 include a sheet 7 and an epoxy resin penetration layer 8 coated on the outside thereof, and a polyurea elastic waterproof layer 9 is coated on the outside of the epoxy resin penetration layer 8.

[0030] When the utility model forms a U-shaped structure, it can form the structure through a number of sub-keels, changing the original sheet-like structure into a structure with a certain thickness. Since the cross-section of the sub-keel is a regular hexagon and is hollow, it does not excessively increase the weight of the entire keel. Moreover, when the entire keel is forced to deform, it can resist through the structure of the sub-keel. Among them, the cross-shaped keel frame 3 will strengthen the structure of the U-shaped keel frame 1 to resist the deformation that attempts to occur from the outside to the inside or from the inside to the outside. Among them, the central keel frame 2 is used as the main supporting object to support the cross-shaped keel frame 3. And when the external force is transmitted through the U-shaped keel frame 1 and the cross-shaped keel frame 3, it can also be borne by the central keel frame 2 and resist the external force, making it difficult for the entire keel to deform, having high bending resistance. The horizontal reinforcement plate 6 and the vertical reinforcement plate 5 not only provide further structural strength for the entire keel, but also provide a plane for the entire keel during subsequent installation, so that the keel can be in surface contact with other structures. The epoxy resin penetration layer 8 and the polyurea elastic waterproof layer 9 bring good protection performance to the entire keel, making it not easily damaged and having a relatively long service life.

[0031] The above is only the preferred specific implementation manner of the utility model, but the protection scope of the utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the utility model, according to the technical solution of the utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the utility model.
