Detailed Description

In order to make the purpose, technical solutions and advantages of the present application clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the drawings in the embodiments, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all the embodiments. All other embodiments obtained by a person skilled in the art without making any inventive step, based on the given embodiments, fall within the scope of protection of the present application.

In the description of the present application, it is to be understood that the terms "upper", "lower", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, are only for convenience in describing the present application and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present application.

In the description of the present application, the terms "first", "second", and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implying any number of technical features indicated.

The utility model discloses a light gauge steel, it has higher intensity, and whole height is little, exquisite bending resistance, can be used for refuting the fossil fragments fastener of connecing outer edge formula.

This embodiment discloses a light gauge steel, which in this embodiment is substantially pi-shaped in cross-section. As shown in fig. 1, the plate comprises a connecting portion 1 and a ridge portion 2, wherein the connecting portion 1 and the ridge portion 2 are of an integral structure, the ridge portion 2 is formed by bending a plate body 100 downwards along the inner side to form a first plate layer 21 and a second plate layer 22, and the first plate layer 21 and the second plate layer 22 are mutually close to form a double-layer structure. In the description of the present invention, the term "close" may mean that the first board layer 21 and the second board layer 22 are completely attached together, or have a fine pitch therebetween, or have a portion attached together and a portion having a fine pitch therebetween.

In the present embodiment, the strip-shaped plate body 100 is processed into the light gauge steel by a roll forming process. The material of the plate body 100 is the same as that used in the conventional light gauge steel. Preferably, the plate body 100 is roll-formed to have the ridge 2, the connecting portion 1, the connecting portion 3, the groove 4, and the like.

As shown in fig. 3, the connecting portion 1 is provided at its middle portion with a longitudinally extending groove 4. The groove 4 is provided with a nail hole 5 which is matched with a special expansion bolt to be hung on a building. The recess 4 is configured to receive a nut to form a concealed fit. As shown in fig. 1 and 2, the nail holes 5 are provided in a plurality and are distributed discretely in the grooves 4. Therefore, as another assembly form of the light steel keel, the light steel keel can be fixed on the wall body by using the air nail, and specifically, the air nail is nailed into the wall body opposite to the part 10 of the connecting part 1 where the nail hole 5 is not arranged.

In this embodiment, the light gauge steel is further provided with a connection portion 3, the connection portion 3 is located outside the ridge portion 2, the connection portion 3 is integrally connected with the first slab 21, and the cross section of the light gauge steel is substantially pi-shaped. The connection part 3 can be used for connecting an outer edge type keel clamping piece (which is an integrated wall fitting and is not shown in the figure).

As shown in fig. 3, the lower end of the first sheet layer 21 and the lower end of the second sheet layer 22 are connected by an arc-shaped section 23. By providing the arc-shaped section 23, it is possible to avoid the plate body 100 from being excessively bent, thereby ensuring the strength of the ridge portion 2 and preventing the plate body 100 from being excessively machined and broken.

It should be noted that the light steel keel with the above structure can be used not only as a component of an integrated wall surface, but also as a component of a suspended ceiling.

The above-mentioned embodiment is only the preferred embodiment of the present invention, and does not limit the protection scope of the present invention according to this, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
