[0046] The drip groove 103 is grooved on the top of the steel plate 1, and the drip groove 103 is provided with a "V" shaped groove;

[0047] The bracket 2 is threadedly connected to the lower front end of the steel plate 1;

[0048] Multiple sets of fixing plates 3 are provided, and the fixing plates 3 are welded to the top of the steel plate 1 respectively. The fixing plates 3 are provided with a slotted structure.

[0049] Multiple sets of connecting devices 4 are provided, and the connecting devices 4 are respectively installed on the top of the steel plate 1;

[0050] Multiple sets of connecting bolts 5 are provided, and the connecting bolts 5 are threadedly connected to the top of the steel plate 1.

[0051] The steel plate 1 includes: a left connecting block 101 and a right connecting block 102.

[0052] The left connecting block 101 is welded to the left side of the steel plate 1. The left connecting block 101 has a "U" shaped structure and is provided with threaded holes.

[0053] The right connecting block 102 is welded to the right side of the steel plate 1. The right connecting block 102 is provided with threaded holes. In use, when the width of the steel plate 1 is insufficient and connection is required, the right connecting block 102 of one set of steel plates 1 is inserted into the left connecting block 101 of another set of steel plates 1, and the threaded holes of the right connecting block 102 and the left connecting block 101 are aligned. At this time, the two sets of steel plates 1 are connected by connecting bolts 5, realizing the combination of steel plates 1, which facilitates operation, ensures the neatness of the connection, increases the quality of construction, and improves work efficiency.

[0054] The bracket 2 includes: a support threaded hole 201 and an anti-backflow component 202;

[0055] Multiple sets of support threaded holes 201 are provided, and the support threaded holes 201 are respectively opened and set on the top of the bracket 2;

[0056] Multiple sets of anti-backflow components 202 are provided. The anti-backflow components 202 are welded to the top of the bracket 2. The anti-backflow components 202 are provided with "V"-shaped grooves. The "V"-shaped grooves of the anti-backflow components 202 overlap and connect with the drip grooves 103. In use, the overlap and connection between the "V"-shaped grooves of the anti-backflow components 202 and the drip grooves 103 prevents rainwater from flowing back through the bottom of the steel plate 1 when it rains, increases the comfort of living, and ensures the quality of the project.

[0057] The fixing plate 3 includes: a front connecting block 301 and a rear connecting block 302;

[0058] Multiple sets of front connecting blocks 301 are provided. The front connecting blocks 301 are welded to the upper front side of the fixing plate 3 respectively. The front connecting blocks 301 are provided with slots and threaded holes.

[0059] Multiple sets of rear connecting blocks 302 are provided. The rear connecting blocks 302 are welded to the upper rear side of the fixed plate 3. The rear connecting blocks 302 are provided with threaded holes. In use, when the length of the steel plate 1 is insufficient and connection is required, the rear connecting blocks 302 of one set of steel plates 1 are inserted into the front connecting blocks 301 of another set of steel plates 1. The threaded holes of the front connecting blocks 301 and the rear connecting blocks 302 are aligned. At this time, the two sets of steel plates 1 are connected by connecting bolts 5, realizing the combination of steel plates 1, which facilitates operation, ensures the neatness of the connection, increases the quality of construction, and improves work efficiency.

[0060] The connecting device 4 includes: an operating pin 401 and a handle 403;

[0061] Multiple sets of operating pins 401 are provided, and the operating pins 401 are slidably connected to the slots of the fixed plate 3 respectively;

[0062] Multiple handles 403 are provided, and each handle 403 is welded to the back of the operating pin 401. During use, when the steel plate 1 is connected, the operator's hand is easily cut because the steel plate 1 is generally thin. The problem of cutting the hand can be effectively avoided by operating the handle 403. At the same time, it is convenient to operate and speeds up the work efficiency.

[0063] The connecting device 4 also includes: a limit plate 402 and an alert switch 404;

[0064] The limiting plate 402 is welded to the front of the handle 403;

[0065] The reminder switch 404 is fixedly connected to the front of the limit plate 402. In use, the limit plate 402 is inserted into the slot of the front connecting block 301. When two sets of steel plates 1 are connected, the rear connecting block 302 of one set of steel plates 1 enters the slot of the front connecting block 301 of the other set of steel plates 1. When aligned, the rear connecting block 302 touches the reminder switch 404. At this time, the connecting device 4 issues a reminder, which increases the efficiency of connecting the steel plates 1 and adds a reminder function.

[0066] The specific usage and function of this embodiment are as follows:

[0067] First, when the width of steel plate 1 is insufficient and connection is required, insert the right connecting block 102 of one set of steel plates 1 into the left connecting block 101 of another set of steel plates 1, aligning the threaded holes of the right connecting block 102 and the left connecting block 101. Then, connect the two sets of steel plates 1 using connecting bolts 5, achieving the combination of steel plates 1. This facilitates operation, ensures the neatness of the connection, increases construction quality, and improves work efficiency. Next, when the length of steel plate 1 is insufficient and connection is required, insert the rear connecting block 302 of one set of steel plates 1 into the front connecting block 301 of another set of steel plates 1. The rear connecting block 302 of one set of steel plates 1 enters the slot of the front connecting block 301 of the other set of steel plates 1. When aligned, the rear connecting block 302 touches the reminder switch 404, at which point the connecting device 4 issues a reminder to align the threaded holes of the front connecting block 301 and the rear connecting block 302. Then, connect the two sets of steel plates 1 using connecting bolts 5, achieving the combination of steel plates 1. This facilitates operation, ensures the neatness of the connection, increases construction quality, and improves work efficiency.

[0068] Then, the bracket 2 is also equipped with an anti-backflow component 202. The anti-backflow component 202 has a "V"-shaped groove that overlaps with the drip groove 103, which prevents rainwater from flowing back through the bottom of the steel plate 1 when it rains, increases the comfort of living, and ensures the quality of the project.
