Description

Technical Field

[0001] This utility model relates to the field of light steel keel, and more particularly to a structural keel for light steel houses. Background Technology

[0002] With the rapid development of prefabricated buildings, light steel frame houses have been widely used in residential buildings, villas, and temporary structures due to their advantages such as short construction cycles, environmental friendliness, energy efficiency, and high space utilization. The structural frame, as the load-bearing skeleton of a light steel frame house, directly affects the overall quality of the building due to its structural stability, ease of installation, and seismic performance.

[0003] Currently, traditional light steel frame houses mostly use C-shaped or U-shaped steel keels. When fixing two keels, it is usually necessary to cut a short section of keel and insert it between the two keels. Before inserting the short keel, it is also necessary to manually adjust the shape of the short keel so that it can be smoothly inserted into the two keels, and then fix it by bolts or welding. However, the above connection method is not only time-consuming and labor-intensive, but also has the problem of insufficient connection strength. At the same time, stress concentration is prone to occur at the connection nodes, which may loosen or deform after long-term use, making it impractical. Therefore, a structural keel for light steel frame houses is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a structural keel for light steel houses, which aims to improve the traditional keel connection method in the prior art, which is not only time-consuming and labor-intensive but also has the problem of insufficient connection strength. At the same time, stress concentration is prone to occur at the connection nodes, which may lead to loosening or deformation after long-term use and make it impractical.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a structural keel for a light steel house, comprising two keel bodies, with a connector installed between the two keel bodies. The keel bodies and the connector are movably connected by bolts. The connector includes a connecting plate, with mounting plates fixedly connected to the left and right sides of the connecting plate. Mounting grooves are provided on the front and rear sides of the mounting plates, and the keel bodies are movably connected to the mounting grooves.

[0006] As a further description of the above technical solution:

[0007] The connecting plate and the mounting plate are fixedly connected by four reinforcing ribs.

[0008] As a further description of the above technical solution:

[0009] An auxiliary hole is provided in the middle of the connecting plate.

[0010] As a further description of the above technical solution:

[0011] The lower left and right sides of the keel body are fixedly connected to a base plate, and the keel body and the base plate are integrally formed.

[0012] As a further description of the above technical solution:

[0013] The keel body has multiple mounting holes in the middle, and the base plate has multiple wire holes on both the left and right sides.

[0014] As a further description of the above technical solution:

[0015] The upper left and right sides of the inner wall of the keel body are fixedly connected with multiple reinforcing ribs, and the lower part of the reinforcing ribs is set in an arc shape.

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

[0017] 1. In this utility model, by setting up the mutual cooperation between components such as the keel body and connectors, the connection between keels is more time-saving and labor-saving, and the connection nodes are more stable, which can effectively improve the practicality of the keel structure.

[0018] 2. In this utility model, by setting reinforcing ribs inside the keel and reinforcing ribs on the connectors, the bending stiffness of the keel and connectors can be improved, thereby further improving the service life of the keel structure and making it more practical.

[0024] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only part of the embodiments of the present utility model, not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Reference Figure 1 - Figure 3 , the present utility model provides an embodiment: a structural keel for a light steel house, comprising two keel bodies 1, which is a light steel house structure. A connecting member 2 is jointly installed between the two keel bodies 1, which is used for cooperating with the connection between the two keel bodies 1. The keel bodies 1 and the connecting member 2 are movably connected by bolts.

[0026] Further, the connecting member 2 comprises a connecting plate 21 for cooperating with connecting various components. The left and right sides of the connecting plate 21 are both fixedly connected with mounting plates 22 for cooperating with the connection of the keel bodies 1. Reinforcing ribs 23, the number of which is four, are fixedly connected between the connecting plate 21 and the mounting plates 22, for improving the strength of the connecting member 2. An auxiliary hole 24 is formed in the middle of the connecting plate 21 for reducing the weight of the connecting member 2. Mounting grooves 221 are formed on the front and rear sides of the mounting plates 22 for cooperating with the keel bodies 1, and the keel bodies 1 are movably connected with the mounting grooves 221.

[0027] Still further, bottom plates 12 are fixedly connected to the left and right sides of the lower part of the keel body 1, which are matched with the keel body 1 and integrally formed with the keel body 1. The cross-section of the keel is in a "Ω"-shape. A plurality of mounting holes 11 are formed in the middle of the keel body 1 for cooperating with the installation of the keel. A plurality of wire passing holes 121 are formed on the left and right sides of the bottom plate 12 to facilitate subsequent pipeline arrangement. A plurality of reinforcing ribs 13 are fixedly connected to the left and right sides of the upper inner wall of the keel body 1, and the lower parts of the reinforcing ribs 13 are arranged in a circular arc shape, which can better disperse stress and improve the strength of the keel.

[0028] Working principle: During keel installation, connector 2 is installed between two keel bodies 1, and the side of the keel body 1 can be locked in the mounting groove 221 of the mounting plate 22. The mounting groove 221 can tightly wrap the side of the keel body 1. Then, the keel body 1 and connector 2 are fixed together by bolts, etc., to ensure that the two keel bodies 1 do not wobble relative to each other in the horizontal direction and form a synchronously stressed overall frame. At the same time, four reinforcing ribs 23 are set between the connecting plate 21 and the mounting plate 22 to prevent breakage due to stress concentration at the connection between the mounting plate 22 and the connecting plate 21, which significantly improves the bending and tensile resistance of connector 2. When the keel body 1 is installed, it can be connected to the house wall panel, floor slab or roof structure by bolts, rivets and other fasteners through multiple mounting holes 11 opened in the middle. At the same time, by setting reinforcing ribs 13 in the keel body 1, the top of the keel body 1 can be prevented from collapsing or deforming when bearing the roof load.
