[0030] See also Figure 1-4 A concrete truss floor deck support structure and construction method in this embodiment include a concrete truss floor deck body 1, two fixing rods 2 are fixedly connected to the bottom surface of the concrete truss floor deck body 1, a connecting rod 15 is fixedly connected between the two fixing rods 2, and a support column 3 is fixedly connected to the top surface of the connecting rod 15, and the support column 3 is fixedly connected to the concrete truss floor deck body 1.

[0031] The left and right sides of the connecting rod 15 are fixedly connected to the first articulated frame 14, the two first articulated frames 14 are hinged to the connecting blocks 13, the top surfaces of the two connecting blocks 13 are movably connected to the support rods 11 through bearings, and the bottom surface of the concrete truss floor deck body 1 is provided with two slide grooves 4, the two slide grooves 4 are slidably connected to the sliders 5, the bottom surfaces of the two sliders 5 are fixedly connected to the second articulated frame 9, and the two second articulated frames 9 are hinged to the first screw 10 with one end extending to the inside of the support rod 11.

[0032] The top surfaces of the two support rods 11 are each provided with a first threaded hole, and the two first screw rods 10 extend into the inside of the two first threaded holes and are threadedly connected thereto, respectively. The slide groove 4 and the slider 5 are both T-shaped, and the two support rods 11 are relatively inclined.

[0033] Specifically, the support rod 11 is rotated to rotate, and the slider 5 is driven to move through the threaded connection between the first screw rod 10 and the support rod 11. The support rod 11 is driven to flip over under the action of the first articulated frame 14. When the slider 5 is in a suitable position, the slider 5 is supported by the sliding connection between the slider 5 and the slide groove 4, thereby improving the stability of the concrete truss floor deck body 1.

[0034] In this embodiment, a connecting assembly is provided on the support column 3, and the connecting assembly includes two mounting rods 17, and the two mounting rods 17 are respectively fixedly connected to the opposite side surfaces of the two support rods 11, and two fixing grooves 16 are provided inside the support column 3, and the fixing frames 12 are placed inside the two fixing grooves 16, and the interiors of the two fixing frames 12 are movably connected with rotating rods 19 through bearings, and the left and right sides of the support column 3 are provided with yielding grooves 23, and the outer peripheral walls of the two rotating rods 19 are fixedly sleeved with a clamping rod 18 with one end passing through the yielding groove 23 and extending to the outside thereof, and the bottom surfaces of the two clamping rods 18 are provided with placement holes 20, and the two mounting rods 17 extend to the insides of the two placement holes 20 respectively, and the insides of the two placement holes 20 are fixedly connected with telescopic rods 21, and the two telescopic rods 21 are respectively fixedly connected to the two mounting rods 17, and the outer peripheral walls of the two telescopic rods 21 are sleeved with springs 22 that are respectively fixedly connected to the placement holes 20 and the mounting rods 17.

[0036] Specifically, when the support rod 11 flips, it drives the mounting rod 17 to move and then stretches the telescopic rod 21 and the spring 22, so that the mounting rod 17 moves. When the mounting rod 17 is at the maximum stroke, the sliding connection between the fixing frame 12 and the fixing groove 16 and the extrusion force generated between the mounting rod 17 and the support rod 11 push the fixing frame 12 to move, thereby avoiding interference with the movement trajectory of the support rod 11.

[0037] In this embodiment, a driving assembly is provided on the concrete truss floor deck body 1, and the driving assembly includes two driving rods 8, and the two driving rods 8 are movably connected to the inside of two slide grooves 4 through two bearings respectively.

[0039] Specifically, the driving rod 8 is turned to rotate, and the slider 5 is driven to move through the threaded connection between the second screw rod 7 and the driving rod 8 , and the stability of the slider 5 is improved through the fit between the rubber pad 6 and the slide groove 4 .

[0040] A construction method for a concrete truss floor deck support structure comprises the following steps:

[0041] Step 1: Fix the fixing rod 2 on the foundation support column by means of bolts.

[0042] Step 2: Rotate the driving rod 8 and the supporting rod 11 to rotate, drive the slider 5 to move, adjust the supporting angle of the supporting rod 11, and then adjust the supporting force.

[0043] Step 3: The support rod 11 moves to drive the mounting rod 17 to move, thereby supporting the support rod 11 .

[0044] Step 4: The fixing slot 16 and the fixing frame 12 are slidably connected to drive the clamping rod 18 to move, thereby stably supporting the support rod 11 .

[0045] The working principle of the above embodiment is:

[0046] The driving rod 8 and the supporting rod 11 are rotated to rotate the driving rod 8 and the supporting rod 11, and the slider 5 is driven to move through the threaded connection between the first screw rod 10 and the supporting rod 11 and the threaded connection between the second screw rod 7 and the driving rod 8. Under the action of the first articulated frame 14, the supporting rod 11 is driven to flip. When the slider 5 is in a suitable position, the slider 5 is supported by the sliding connection between the slider 5 and the slide groove 4. The fit between the rubber pad 6 and the slide groove 4 improves the stability of the slider 5, thereby supporting the concrete truss floor deck body 1 and improving the stability of the concrete truss floor deck body 1.
