Detailed Description

The technical solutions in the embodiments of the present invention will be described in detail below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-5, a vertical light gauge steel includes: a plurality of positive U-shaped recess 11 and a plurality of 12 recesses of falling U-shaped, characterized by: the plurality of regular U-shaped grooves 11 and the plurality of inverted U-shaped grooves 12 are combined into a whole in a continuous and staggered manner; the bottom surfaces of the plurality of regular U-shaped grooves 11 form one side connecting and fixing surface, the bottom surfaces of the plurality of inverted U-shaped grooves 12 form the other side connecting and fixing surface, and the fixing keel 1 and the connecting piece 2 are connected on the fixing and connecting surface by using a fastening piece; the spaces of the plurality of regular U-shaped grooves 11 and the spaces of the plurality of inverted U-shaped grooves 12 are used for placing the tails of the fasteners.

In the specific operation, the bottom surfaces of the plurality of regular U-shaped grooves 11 jointly form a side connecting surface which can be connected with the keel 1 and the connecting piece 2. The bottom surfaces of the inverted U-shaped grooves 12 jointly form the connecting surface at the other side, and also can be connected with the keel 1 and the keel 2. As shown in fig. 2, in the actual construction process of the light gauge steel suspended ceiling, the lower end of the vertical light gauge steel is required to be respectively connected with the keel 1 and the connecting piece 2 on two sides, and the rivet tail 4 used in hidden connection can be arranged in the space of the positive U-shaped groove 11 and the inverted U-shaped groove 12, so that the flatness of the connecting planes on two sides cannot be damaged, and the connection and fixation of two sides can be realized in a grading manner. Due to the structural characteristics of the U-shaped groove, the keel is naturally provided with the plurality of reinforcing ribs 31, so that the stress strength of the keel is enhanced, and the keel is not easy to deform. In the prior art, a common solution is to use a C-shaped cladding keel 5 and a square tube 6 as vertical keels. As shown in fig. 4, when using C shape clad can fossil fragments 5 to use as vertical fossil fragments, because its structural feature can only realize the unilateral and connect, when needs connect fossil fragments 1 and connecting piece 2 in 5 bottom both sides of C shape clad can only form the built-up piece after fixed with the folding connection of three, can carry out subsequent construction process again, will cause two drawbacks like this: firstly, as the size of the assembly part is increased (the length of the keel 1 can reach 3 meters), the working difficulty of the subsequent process is greatly increased; secondly, connect the three simultaneously and can increase the connection degree of difficulty, reduce the efficiency of construction. If 5 shows, use square pipe 6 to use as vertical fossil fragments, when needs connect fossil fragments 1 and connecting piece 2 in 6 bottom both sides of square pipe, though can realize two sides and connect in grades, nevertheless also cause two drawbacks because its structural feature: firstly, the consumption of materials is increased, and the use cost is high; secondly, if the upper end of the square pipe 6 only realizes the continuous force receiving of the single side, the whole force receiving of the square pipe 6 is uneven due to the fact that the lower end is stressed by the double sides, and the local position of the stress surface of the upper end has the risk of deformation. If the upper end and the two sides of the square pipe 6 are connected, the construction amount can be increased, the construction efficiency is reduced, and the labor intensity of constructors is improved.

Preferably, a vertical light gauge steel, characterized by: the thicknesses of the groove walls of the plurality of regular U-shaped grooves 11 and the plurality of inverted U-shaped grooves 12 are consistent; the two adjacent positive U-shaped grooves 11 and the two adjacent inverted U-shaped grooves 12 share one adjacent side edge;

in the specific operation, as shown in fig. 1, the wall thickness of the regular U-shaped groove 11 is consistent with that of the inverted U-shaped groove 12, and two adjacent regular U-shaped grooves 11 and two adjacent inverted U-shaped grooves 12 share one side edge, so that the same strip steel can be conveniently used for realizing the mechanized production of the structure, and the production cost is optimized and reduced. As shown in fig. 2, because two adjacent regular U-shaped grooves 11 and inverted U-shaped grooves 12 share one side, when the two side surfaces of the lower end of the vertical light steel keel are connected with the keel 1 and the connecting piece 2, the shared side can conduct and balance the stress on the two sides, and the stress imbalance caused by the stress conditions of the upper end and the lower end of the keel can be avoided, so that the risk of deformation of the vertical keel can be avoided.

Preferably, a vertical light gauge steel, characterized by: the bottom surfaces of the plurality of regular U-shaped grooves 11 and the plurality of inverted U-shaped grooves 12 are provided with connecting hole groups 21 which are distributed uniformly in a plurality of groups and are used for connecting the fixing keel 1 and the connecting piece 2 by using fasteners.

In the specific operation, as shown in fig. 2, the preset connecting hole group 21 helps the constructor to improve the construction efficiency and reduce the labor intensity. Because the connecting hole groups 21 are in a plurality of groups and are uniformly distributed, constructors can obtain the connecting hole groups by cutting the vertical light steel keel according to the actual required size, so that the construction is more convenient, and meanwhile, the material waste is reduced.

Preferably, a vertical light gauge steel is characterized in that: the difference between the total number of the regular U-shaped grooves 11 and the total number of the inverted U-shaped grooves 12 is 1.

In the specific operation, as shown in fig. 2, when the difference between the total number of the regular U-shaped grooves 11 and the total number of the inverted U-shaped grooves 12 is 1, the centers of the connecting hole groups 21 of the keels 1 and the centers of the connecting hole groups 21 of the connecting pieces 2 can be consistent and distributed in the center positions of the vertical light steel keels, so that the best stress of the whole keel connecting module is achieved.

Preferably, a vertical light gauge steel is characterized in that: the vertical light steel keel is made of metal; the production method of the vertical light steel keel is characterized in that strip steel is formed by mechanical continuous cold rolling.

In the concrete operation, the stress strength of the vertical light steel keel can be ensured by the metal material, and meanwhile, the material is relatively cheap and has excellent cost performance. In the current production technology, the strip steel is used for producing the light steel keel by mechanical continuous cold rolling forming, and the method has the advantages of high production efficiency and low labor intensity of workers. Compared with the production of the square tube 6, the complex processes such as welding and the like are omitted, so that the production cost is reduced, and the economic benefit is improved.

Preferably, a vertical light gauge steel is characterized in that: the fastener is a blind rivet 3.

In the specific operation, as shown in fig. 2, in the current technical process, the fasteners used for connecting the vertical light steel keel, the keel 1 and the connecting piece 2 are self-tapping screws and blind rivets 3. The reason why the blind rivet 3 is selected as the fastener is as follows: firstly, the connection strength and the stability of the self-plugging rivet are superior to those of a self-tapping screw; secondly, after fixed connection is completed, the tail length of the core pulling rivet is smaller than that of the self-tapping screw, so that the widths of the side edge of the positive U-shaped groove 11 and the side edge of the inverted U-shaped groove 12 are reduced, and the using amount of raw materials is reduced.
