[0035] The present invention will be further described in detail below in conjunction with the accompanying drawings so that those skilled in the art can implement the invention with reference to the description.

[0036] It should be understood that terms such as “having”, “including” and “comprising” used herein do not specify the existence or addition of one or more other elements or combinations thereof.

[0037] like Figure 1 , Figure 2 and Figure 3 As shown, the utility model provides a tall template support structure for a passage of a convention and exhibition center, which includes:

[0038] The support frame body 1 comprises a vertical steel pipe 11, a transverse steel pipe, a horizontal scissors brace, a vertical scissors brace, a diagonal brace 12 and a diagonal tie rod, wherein the diagonal brace is arranged perpendicularly to the diagonal column formwork, and the diagonal tie rod is arranged parallel to the diagonal column formwork;

[0039] The screw 2, the lower end of which is inserted into the vertical steel pipe 11 or the diagonal brace 12;

[0040] A screw adjuster 3, which is arranged at the top end of the vertical steel pipe 11 and fixes the screw 2 to the vertical steel pipe 11 or the diagonal brace 12;

[0041] A U-shaped bracket 4, which is arranged at the top end of the screw rod 2;

[0042] A square timber main rib 5, which is clamped on the U-shaped bracket 4;

[0043] And a triangular adjustment block 6, which is fixed above the square wood main rib 5, and the inclined surface of the triangular adjustment block 6 is parallel to the surface of the inclined column formwork 7.

[0044] The inclined column formwork uses 15mm thick coated multi-layer board, and the formwork height is 50mm above the bottom of the beam.

[0045] After the inclined column formwork is installed, 50×100mm wooden squares, Φ48 steel pipes and Φ16 bolts are used to tighten the column hoop locking formwork, with a spacing of 300 along the inclined column direction. Use steel pipes to make diagonal braces (spacing 600mm) from the small crossbar at the bottom of the board to support the side formwork, and pull the top formwork column hoop to ensure overall stability.

[0046] The frame is continuously equipped with longitudinal and transverse sweeping rods and horizontal rods. The longitudinal sweeping rod is fixed to the vertical rod at a distance of no more than 200mm from the top of the base with a right-angle fastener, and the transverse sweeping rod is fixed to the vertical rod just below the longitudinal sweeping rod. The distance between the top horizontal rod and the U-shaped support at the top of the vertical rod is no more than 300mm, and the horizontal tie rod step is 1.5m. Each longitudinal and transverse step must be pulled in place; a horizontal reinforcement layer is set at the top of the high-support formwork frame. When the floor height is 8 to 20 meters, a horizontal tie rod is added between the two horizontal tie rods at the top step; the high-support formwork frame longitudinal and transverse horizontal tie rods are tied together in high and low spans, and the horizontal tie rods of the template brackets reserved for the adjacent layers are pulled together as a whole, and are pulled through and span at least more than two spans.

[0047] A longitudinal brace is set every 4 rows of bracket poles on the four sides and in the middle of the bracket, and it is set continuously from bottom to top. Every 4 rows of poles are set every 2 steps from the top skin downward. The inclined column support system adopts a full-floor scaffolding set on the outside of the structure, with a pole spacing of 600mm and a horizontal bar spacing of 1500mm. There are five columns of vertical poles under the inclined column, one column at 200mm on both sides of the inclined column, and three columns under the inclined column. At 600mm on both sides of each inclined column, the vertical poles are encrypted along the inclined column direction as the inclined column support, with a spacing of 600mm along the inclined column direction. And it is connected to the full-floor scaffolding as a whole with a horizontal rod. The horizontal rod step is 1500mm, and the small horizontal rod and the top support are fixed on the inclined column support pole according to the slope of the inclined column and the angle of the bottom template, with a spacing of less than 600mm. After the small horizontal rod and the top support are installed, the hanging line is used to check the distance between the plumb bob and the edge line of the inclined column foundation to ensure the overall slope of the inclined column. After inspection, install the bottom formwork and temporarily fix it with short wooden planks. After tying the inclined column reinforcement, install the side and top formwork, and install the column hoop. Finally, use steel pipes to add diagonal braces on the side of the inclined column, and fix the diagonal braces on the overall external frame to ensure the lateral stability of the inclined column. And add support rods under the inclined column along the direction of the inclined column, with a spacing of 400mm. Under the premise of ensuring that the overall size and slope of the inclined column meet the design requirements, the inclined column is tilted 10mm inward as a whole. This is to offset the overall sinking caused by the deadweight of the concrete when pouring concrete.
