Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0019] In the description of this utility model, "first feature" or "second feature" may include one or more of these features. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of technical features being described. Therefore, features specified as "first" or "second" may explicitly or implicitly include one or more of these features.

[0020] like Figure 1-Figure 3 A light steel keel connection structure shown includes a keel beam 1 and a connection piece 2.

[0021] like Figure 2 As shown, the keel beam 1 is a channel steel member with a bottom plate in the middle and vertical side plates on the left and right sides, and the upper ends of the side plates are curled inward and a spacing groove is formed between the side plates, that is, the keel beam 1 is an inwardly curled channel steel member.

[0022] like Figure 3 As shown, the connecting member 2 includes a U-shaped plate 3, an insert plate 4 and a clamping plate 5. The U-shaped plate 3 opens downward and extends in the front-to-back direction. The U-shaped plate 3 includes a left plate body and a right plate body arranged relatively to each other. The front and rear ends of the left plate body are respectively provided with an insert plate 4 bent to the left. The right plate body is provided with a avoidance opening 6, which passes through the U-shaped plate 3 upward. A vertical elastic clamping plate 5 is provided at the avoidance opening 6, and a protrusion 7 is provided on the left side of the clamping plate 5.

[0023] In specific use, such as Figure 1 As shown, there are two keel beams 1 arranged in a T-shaped intersection via a connector 2. The two insert plates 4 of the connector 2 are respectively inserted into the two spacing slots of one keel beam 1. Then, the U-shaped plate 3 is lowered onto the curled edge of the other keel beam 1. When the protrusion 7 hits the curled edge, it pushes the clamping plate 5 outward, causing it to elastically deform. When the U-shaped plate 3 moves downward until the protrusion 7 abuts the lower end of the curled edge at that location, the clamping plate 5 automatically returns to its original position.

[0024] At this time, one of the two keel beams 1 is limited by the inserting plate 4, and the other is limited by the protrusion 7, so that the two keel beams 1 can be effectively connected. This connection structure is easy to operate and use.

[0025] If disassembly and adjustment are required later, the clamping plate 5 can be manually moved outward to separate the protrusion 7 from the curling edge, and then the connecting piece 2 can be taken out upward and then slid outward to separate the two keel beams 1.

[0026] In a further configuration, the lower side of the protrusion 7 is an arc-shaped surface, and the length of the clamping plate 5 should be able to extend upward beyond the U-shaped plate 3, so that it is convenient to manually pry the clamping plate 5 outward.

[0027] In summary, this solution mainly utilizes a U-shaped plate 3 with an insert plate 4 and a protrusion 7 to connect two inner-curled keel beams 1. This connection method is simple, easy to assemble and disassemble, and highly practical.

[0028] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
