[0037] Reference Figure 4 A first fixing block 21 is fixedly connected to one side of the bottom of the left bottom plate 1, and a second fixing block 22 is fixedly connected to one side of the bottom of the right bottom plate 1. One side of the first fixing block 21 is in contact with one side of the second fixing block 22. A bolt 23 is threadedly connected to the inside of the second fixing block 22. One end of the bolt 23 is threadedly connected to the inside of the first fixing block 21. A thread groove 24 is provided in the middle of one side of the first fixing block 21, and one end of the bolt 23 is located inside the thread groove 24.

The first fixing block 21 and the second fixing block 22 can be fixed together by the bolt 23. By having one end of the bolt 23 located inside the thread groove 24, the fixing can be more convenient and quick, saving time and effort.

[0038] Working principle: When in use, first fix one end of the web reinforcement 18 in the fixing groove 19 opened on one side of the middle of the connecting piece 2, then place the connecting piece 2 on the bottom plate 1, then hold the handle 15, and insert the rod 3 through the bottom plate 1, so that the rod 3 slides into the groove 20 opened on the other side of the connecting piece 2. At this time, by rotating the rotating rod 14, the threaded rod 4 is driven to rotate, thereby driving the block 5 to move upward. At this time, the block 5 will drive the fixing rod 6 to move upward together, so that the fixing rod 6 is in the second slide groove 25 on both sides of the rod 3. When the fixing rod 6 is fully inserted into the plug rod 3, the block 5 drives the fixing rod 6 to move downward. When the fixing rod 6 is fully inserted into the plug rod 3, the fixing rod 6 will gradually slide out of the second slide grooves 25 on both sides of the plug rod 3. The spring 8 squeezed at the same time will gradually return to its original state and push the fixing rod 6 to rotate outward. When the bottom of the fixing rod 6 is fully extended out of the second slide groove 25, the handle 15 is pulled to adjust the position of the plug rod 3 so that the bottom of the fixing rod 6 is completely fitted with the top of the bottom plate 1, and then the grip rod 11 is held and the fixing piece 10 is rotated to fix the bottom plate 1 and the connecting piece 2 together, and then the upper chord steel bar 16 and the lower chord steel bar 17 are fixed together by the iron wire and the web steel bar 18, and then concrete is poured. When it is necessary to disassemble the bottom plate 1, it is only necessary to rotate the fixing piece 10 first, and then rotate the rotating rod 14 and the threaded rod 4 to make the fixing rod 6 retract into the inside of the plug rod 3, and then pull the handle 15 to remove the plug rod 3 and the bottom plate 1, which is convenient and fast and improves work efficiency. When multiple bottom plates 1 are needed, it is only necessary to fit the first fixing block 21 and the second fixing block 22 fixed at the bottom of the bottom plate 1 to each other, and then rotate the bolt 23 to fix the first fixing block 21 and the second fixing block 22 together to avoid a gap between the two bottom plates 1.
