[0013] The present invention is further described below in conjunction with specific embodiments, the purpose of which is only to provide a better understanding of the content of the present invention. Therefore, the examples given do not limit the protection scope of the present invention.

[0014] A support device for a steel truss floor deck without formwork removal, such as Figure 1 As shown, it is composed of a plurality of support frame bodies, and two adjacent support frame bodies are connected by a cross bar 4.

[0015] like Figure 1 , Figure 3 As shown, the support frame body is composed of a top support 1, a vertical rod 2 and a support leg 3. The top support 1 is composed of a socket rod 101 and a U-shaped support 102. The bottom of the U-shaped support 102 is fixedly connected to the top of the socket rod 101. The U-shaped support 102 is used to clamp the keel under the floor deck. The vertical rod 2 is a hollow steel pipe structure, and the top of the vertical rod 2 is inserted into the lower end of the socket rod 101.

[0016] like Figure 1 , Figure 3 , Figure 4 As shown, the outer wall of the socket rod 101 is provided with a threaded structure, and an adjusting nut 201 is fixedly provided at the top of the vertical pole 2. The socket rod 101 is threadedly connected with the adjusting nut 201. Rotating the socket rod 101 can adjust the length of the socket rod 101 extending out of the top of the vertical pole 2 to adjust the height of the U-shaped support 102.

[0017] like Figure 5 As shown, the support leg 3 is composed of a support column 301, a hinged seat 302, a fixed rod 303 and an oblique hydraulic telescopic rod 304. The support column 301 is a hollow steel pipe, and the lower end of the rod 2 is plugged into the upper end of the support column 301.

[0018] The lower part of the support column 301 is evenly provided with four hinge seats 302 on its outer surface circumferentially, and each hinge seat 302 is fixedly connected to the support column 301 respectively; the upper end of the fixed rod 303 is hinged to the hinge seat 302, and the lower end of the fixed rod 303 is fixedly connected to the fixed end of the oblique hydraulic telescopic rod 304, and the end of the telescopic end of the oblique hydraulic telescopic rod 304 is fixedly connected with a pad 305, which is used to increase the contact area between the oblique hydraulic telescopic rod 304 and the ground, so as to protect the ground.

[0019] A plurality of horizontal hydraulic telescopic rods 306 are axially arranged at the bottom of the support column 301. In this embodiment, four horizontal hydraulic telescopic rods 306 are arranged, and the horizontal hydraulic telescopic rods 306 are arranged one-to-one with the oblique hydraulic telescopic rods 304. The fixed end of the horizontal hydraulic telescopic rod 306 is fixedly connected to the surface of the support column 301, and the telescopic end of the horizontal hydraulic telescopic rod 306 is hinged to the telescopic end of the oblique hydraulic telescopic rod 304. The horizontal hydraulic telescopic rod 306 can limit the opening angle of the fixed rod 303 and the oblique hydraulic telescopic rod 304, ensuring that the fixed rod 303 and the oblique hydraulic telescopic rod 304 will not slip due to the horizontal force being greater than the friction force, thereby improving the stability of the support leg 3.

[0020] like Figure 1 , Figure 2 , Figure 6 As shown, a perforated disc 5 is respectively provided on the supporting column 301 and the upright 2. When two adjacent supporting frames are connected, the connecting pieces 6 at both ends of the cross bar 4 are detachably connected to the perforated disc 5 at their respective corresponding positions. The specific structure is that the cross bar 4 is composed of a transverse sleeve 401 and a transverse telescopic rod 402, one end of the transverse fixed rod 303 is provided with an adjusting nut 2 403, one end of the transverse telescopic rod 402 penetrates the adjusting nut 2 403 and is plugged into the transverse fixed rod 303, and the transverse telescopic rod 402 is threadedly connected to the adjusting nut 2 403.

[0021] One end of the transverse sleeve 401 away from the transverse telescopic rod 402 and one end of the transverse telescopic rod 402 away from the transverse sleeve 401 are respectively fixedly connected with a connecting piece 6, and the connecting piece 6 is a square block structure. One end of the connecting piece 6 away from the transverse sleeve 401 (or the transverse telescopic rod 402) is respectively provided with a horizontal groove 601 and a vertical groove 602, and the horizontal groove 601 and the vertical groove 602 are vertically connected. When the cross bar 4 is connected to the support frame body, the perforated disc 5 is inserted into the horizontal groove 601, and then the limiting pin 7 is aligned with the through hole on the perforated disc 5 and inserted into the vertical groove 602, so that the limiting pin 7 limits the connecting piece 6 to prevent the connecting piece 6 from slipping and separating from the perforated disc 5.

[0022] When this device is used in construction, the specific steps are as follows: S1. Calculate the stress points according to the drawings, determine the arrangement spacing of the support frame body, and then measure and locate according to the stress points and arrangement spacing to determine the position of the support frame body at the construction site.

[0023] S2. Place the support legs 3 of each support frame body at designated positions respectively, and adjust the oblique hydraulic telescopic rod 304 so that the pad 305 falls to the ground and contacts the ground.

[0024] S3, insert the vertical pole 2 from the upper end of the supporting column 301, and connect the adjacent supporting columns 301 and the vertical pole 2 respectively through the cross bar 4.

[0025] S4. Screw the socket rod 101 into the top of the vertical rod 2, and then adjust the height of the U-shaped support 102 by rotating the socket rod 101 according to the height of the floor deck.

[0026] S5. Install the keel above the top support 1.

[0027] S6. Install the formwork-free steel truss floor decking on the keel and the installation is completed.
