The bottom end of the rotating shaft 21 is fixedly connected with a gear 22. The two T-shaped grooves 23 respectively opened in the rectangular opening of the plate body 1 are perpendicular to each other, and the two T-shaped grooves 23 located on one side of the bottom end of the plate body 1 are perpendicular to each other. The tops of the first tooth plate 24 and the second tooth plate 25 are respectively provided with T-shaped grooves 23 matching the "T"-shaped structure. The ends slide on the inner walls of two mutually perpendicular T-shaped grooves 23, and the tooth surface of the gear 22 meshes with one side of the first tooth plate 24 and the second tooth plate 25. One end of the first tooth plate 24 and the second tooth plate 25 are respectively fixedly connected with a groove plate 26, wherein the back of the tooth surface of the first tooth plate 24 is vertically connected to the end of one of the groove plates 26, and the second tooth plate 25 is a "C"-shaped structure as a whole. One end of the second tooth plate 25 is provided with a tooth surface meshing with the gear 22, and the other end is vertically connected to the end of another groove plate 26, see Figures 6 to 9 A rectangular groove 27 is provided on the outer surface of the groove plate 26, a rubber plate 28 is fixedly connected to the inner wall of the groove plate 26, the upper and lower ends of the rubber plate 28 are fixedly connected to the inner wall of the groove plate 26, a plurality of rubber rods 29 are fixedly connected to the side of the rubber plate 28 facing the steel structure column, a sliding groove 210 is provided on the side of the groove plate 26 facing the steel structure column, an octahedral column 211 is slidably connected to the inner wall of the sliding groove 210, and a round rod 212 is fixedly connected to one end of the octahedral column 211, and the plate body 1 Two cylinders 213 are fixedly connected to the adjacent two sides of the rectangular opening, and the outer surface of the round rod 212 slides on the inner wall of the cylinder 213. Two rotating rods 214 hinged to the cylinder 213 are symmetrically arranged on the outer edge of one end. The cylinder 213 is provided with a convex ring at one end facing the groove plate 26. The rotating rod 214 is hingedly connected to the convex ring. The end of the rotating rod 214 away from the cylinder 213 slides on the inner wall of the groove plate 26. An abutting groove 215 is provided at one end of the rotating rod 214. Figure 4 , Figure 6 and Fig.10The middle part of the rotating shaft 21 is coaxially fixedly connected with a ratchet ring 216, and the ratchet ring 216 is located between the gear 22 and the plate body 1. The bottom end of the plate body 1 next to the ratchet ring 216 is respectively fixedly connected with a rectangular block 218 and a rotatable gear rod 217. A spring 219 is provided on one side of the rectangular block 218. The two ends of the spring 219 are respectively fixedly connected to one side of the rectangular block 218 and one side of the gear rod 217. By providing a slot plate 26, the rectangular opening of the plate body 1 is clamped on the surface corner of the steel structure column. After processing, the rotating shaft 21 can be rotated on both sides of the top of the plate body 1, and the gear 22 is controlled to rotate by the rotating shaft 21, so that the gear 22 drives the first The bottom ends of the tooth plate 24 and the second tooth plate 25 slide on the inner walls of the two mutually perpendicular T-shaped grooves 23 respectively, thereby driving the groove plate 26 on one side of the first tooth plate 24 and the second tooth plate 25 to move toward the rectangular opening of the plate body 1 and the steel structure column. When moving, the two groove plates 26 will drive the round rod 212 at one end of the octahedral column 211 to move along the inner wall of the cylinder 213 toward the direction of the groove plate 26. At this time, the two rotating rods 214 at one end of the cylinder 213 connected to the octahedral column 211 will slide in the limiting guide groove in the groove plate 26, and the end connected to the convex ring will rotate, so that the two rotating rods 214 are close to each other. The abutment groove 215 connected to the octahedral column 211 will gradually contact the two inclined surfaces at one end of the octahedral column 211 and push the octahedral column 211 to slide on the inner wall of the slide groove 210 toward the rubber plate 28. After one side of the octahedral column 211 contacts one side of the rubber plate 28, it continues to move and pushes the rubber plate 28 to deform so that a plurality of rubber rods 29 on one side of the rubber plate 28 protrude from the rectangular groove 27 on the outer surface of the groove plate 26. In the process of rotating the shaft 21, the convex teeth on the tooth surface of the ratchet ring 216 contact the gear rod 217 and push the gear rod 217 to rotate and compress the spring 219. When the shaft 21 stops rotating, the spring 219 will return to its original state and push the gear rod 217. A convex tooth on the tooth surface of the ratchet ring 216 is stuck in, so that the ratchet ring 216 and the rotating shaft 21 cannot rotate independently. By setting the supporting device 2, the groove plate 26 and the octahedral column 211 are controlled to move by rotating the rotating shaft 21, so that the rubber plate 28 is deformed to push the rubber rod 29 to protrude from the rectangular groove 27 of the groove plate 26, so as to limit the relative position and angle between the rectangular opening of the plate body 1 and the steel structure column, and support the contact between the two adjacent sides of the rectangular opening of the plate body 1 and the steel structure column. There is no need to support the bottom of the opposite side template by welding the support steel plate on the surface of the steel structure column, which increases the convenience of using the floor decking and saves construction costs.

[0022] Reference Fig.10 As shown, one side of the rectangular block 218 is fixedly connected to two baffles 220, and the two baffles 220 are respectively located on the left and right sides of the spring 219. By setting the baffles 220, the outer surface shape of the spring 219 can be reinforced to avoid the spring 219 from being distorted when deformed to affect normal use as much as possible. Figure 6One side of the first tooth plate 24 and the second tooth plate 25 is respectively fixedly connected with a positioning block 221, and one side of the positioning block 221 slides on one side of the plate body 1. The rotating shaft 21 controls the gear 22 to drive the first tooth plate 24 and the second tooth plate 25 to move so that the positioning block 221 on the back side of the tooth surface of the first tooth plate 24 and the second tooth plate 25 slides on the bottom surface of the plate body 1, further limiting the angle between the first tooth plate 24 and the second tooth plate 25 and the plate body 1, and avoiding the angle of the first tooth plate 24 and the second tooth plate 25 from being deflected when moving as much as possible.

[0023] Reference Fig.11 As shown, a slanted rod 222 is fixedly connected to the back of the tooth surface of the first tooth plate 24, and the slanted rod 222 connected to the first tooth plate 24 is fixedly connected to one side of the corresponding slot plate 26. Another slanted rod 222 is fixedly connected between one end of the second tooth plate 25 connected to the corresponding slot plate 26 and the slot plate 26. By setting the slanted rod 222, the connection between the slot plate 26 and the first tooth plate 24 or the second tooth plate 25 can be reinforced, and bending deformation of the connection between the slot plate 26 and the first tooth plate 24 or the second tooth plate 25 can be avoided as much as possible when one side of the slot plate 26 is subjected to force, see Fig.10 A plurality of first protrusions 223 are fixedly connected to the side of the tooth surface of the ratchet ring 216 facing the gear rod 217, and a second protrusion 224 is fixedly connected to the side of the gear rod 217 facing the ratchet ring 216. The edges of the first protrusion 223 and the second protrusion 224 are arc-shaped. The first protrusion 223 and the second protrusion 224 cooperate with each other. By setting the first protrusion 223 and the second protrusion 224, it is easier to push the gear rod 217 to rotate when the first protrusion 223 at the convex teeth on the outer surface of the ratchet ring 216 contacts the second protrusion 224 on the outer surface of the gear rod 217, and it is not easy to get stuck with each other. See Figure 4 A handle 225 is fixedly connected to the top of the rotating shaft 21, and a plurality of vertical protrusions are fixedly connected to the side wall of the handle 225. By holding the protrusions on the side wall of the handle 225, the handle 225 can be pushed more conveniently to control the rotation of the rotating shaft 21.

[0024] Example 2 Embodiment 2 is substantially the same as Embodiment 1, except that: Reference Figure 1 , Figure 2 , Figure 3 and Fig.12As shown, two sets of protection devices 3 are provided at the bottom of the rectangular opening of the plate body 1, and the protection device 3 includes a baffle plate 31 with an overall "L"-shaped structure. Two support rods 32 are fixedly connected to the top of the baffle plate 31, and rubber blocks 33 are fixedly connected to one end of the two support rods 32 away from the plate body 1. When transporting and stacking the floor decking, the rubber blocks 33 at one end of the two support rods 32 at the bottom of the plate body 1 can be inserted into the T-grooves 23 at the two T-grooves 23 on both sides of the bottom of the plate body 1, and the baffle plate 31 is fixed under the supporting device 2 at the bottom of the plate body 1 to protect the supporting device 2 and avoid collision at the supporting device 2 when transporting the floor decking as much as possible to affect normal use.

[0025] Reference Figure 2 , Figure 3 and Fig.12 As shown, a pull rope 34 is fixedly connected to the bottom end of the baffle 31. The pull rope 34 is an elastic rope with a certain elasticity. When installing the floor deck, the pull rope 34 can be pulled to facilitate the control of the baffle 31 to pull out the rubber block 33 at one end of the round rod 212 from the inside of the T-slot 23. A groove 35 is provided at the bottom end of the baffle 31. Both ends of the pull rope 34 are located inside the groove 35. After the protective device 3 is removed, the pull rope 34 can be inserted into the groove 35 to facilitate the storage of the baffle 31.

[0026] Example 3 See also Fig.13 The method for installing the assembled reinforced truss floor deck with support of the present invention (i.e., the operating principle of the present invention) comprises the following steps: S1. Pull the pull ropes 34 on both sides of the bottom end of the plate body 1, pull out the rubber block 33 on the top of the round rod 212 from the inside of the T-shaped slot 23, remove the baffle 31, and use the lifting equipment to fit the rectangular opening at the end edge of the plate body 1 to the edge corner of the steel structure column, and put the truss body 4 steel bars protruding from both ends of the plate body 1 on the two side surfaces of the steel structure column; S2, the rotating shaft 21 at the top end edge of the rotating plate body 1 controls the gear 22 to rotate, driving the top ends of the first tooth plate 24 and the second tooth plate 25 to move axially on the inner wall of the T-shaped slot 23 respectively, driving the slot plate 26 on one side of the first tooth plate 24 and the second tooth plate 25 to move toward the direction of the steel structure column, and when the two slot plates 26 move, the round rod 212 slides on the inner wall of the cylinder 213 toward the direction of the slot plate 26; S3, one end of the two rotating rods 214 where the grooves 215 are located moves toward the steel structure column, and the rotating rod 214 and the end hinged to the cylinder 213 rotate relatively, and the two abutting grooves 215 move closer along the two inclined surfaces of the octahedral column 211 and push the octahedral column 211 to move in the slide groove 210 toward the rubber plate 28, and the rubber plate 28 deforms and pushes the rubber rod 29 to protrude from the rectangular groove 27 of the groove plate 26; S4. The convex teeth of the ratchet ring 216 contact the gear rod 217, pushing the gear rod 217 to rotate and compressing the spring 219. When the rotating shaft 21 stops rotating, the spring 219 returns to its original state and pushes the gear rod 217 to get stuck in the tooth surface of the ratchet ring 216, so that the ratchet ring 216 and the rotating shaft 21 cannot rotate independently, and the relative position and angle between the rectangular opening of the plate body 1 and the steel structure column are restricted, and the contact between the rectangular opening of the plate body 1 and the steel structure column is supported, and the subsequent floor decking plates are placed on the surface of the steel structure columns, and the floor decking plates and the steel structure columns are welded and fixed.

[0027] Innovation 1) By setting the supporting device 2, the groove plate and the octahedral column 211 are controlled to move by rotating the rotating shaft 21, so that the rubber plate 28 is deformed to make the groove plate 26 and the rubber rod 28 with the protruding rectangular groove 27 press against the surface of the steel structure column, so as to limit the relative position and angle between the rectangular opening of the plate body 1 and the steel structure column, and support the contact between the rectangular opening of the plate body 1 and the steel structure column. It is not necessary to support the lower side formwork by welding the supporting steel plate on the surface of the steel structure column, which makes the truss floor deck more convenient to use and saves construction costs.

[0028] 2) By providing two sets of protection devices 3 on both sides of the bottom end of the plate body 1, when transporting and stacking the floor decking, the rubber blocks 33 at one end of the two round rods 212 at the top of the plate body 1 can be inserted into the two T-shaped grooves 23 on both sides of the bottom end of the plate body 1, and the baffle 31 can be fixed under the supporting device 2 at the bottom end of the plate body 1 to protect the supporting device 2, so as to avoid the supporting device 2 from being affected by collision when transporting the floor decking as much as possible.

[0029] 3) By providing the first protrusion 223 and the second protrusion 224, when the first protrusion 223 on the outer surface of the ratchet ring 216 contacts the second protrusion 224 on the outer surface of the gear rod 217, it is easier to push the gear rod 217 to rotate and is not easy to get stuck with each other.
