[0042] Embodiment 4

[0043] As Figure 1 shown, the embodiment is further improved on the basis of embodiment 3, as follows:

[0044] The first row of steel pipes in the ladder-type steel pipe support 310 is the highest, and the heights of the other rows are sequentially reduced. The distance between the first row of steel pipes in the ladder-type steel pipe support 310 and the first formwork 1 is 30 cm, and the distance between the first row of steel pipes in the ladder-type steel pipe support 310 and the second formwork 2 is 30 cm. The horizontal, vertical and step distances of the other steel pipes can be set according to 1.5 m to 2 m, and three rows are arranged in a “ladder-type” manner. After the installation of the steel bars is completed, the formwork is installed, and the water stop counter-pulling screw rod 4 is simultaneously arranged at the center of the rectangular range of the support system. In addition, the inclined connecting rod is arranged in the rectangular support of the ladder-type steel pipe support 310 to form a “triangular” stable system support structure. The embedded part 330, the ladder-type steel pipe support 310 and the water stop counter-pulling screw rod 4 jointly form a combined formwork support system to ensure the stability of the formwork support system during the concrete pouring process.

[0045] Detailed description of the arrangement of the ladder-type steel pipe support 310:

[0046] Stand: According to the position of the embedded steel bar, the installation position of each floor stand is determined. In the longitudinal direction of the wall body, the innermost row (the first row) of stands is 300 mm away from the wall surface, and the height of the first row of stands is flush with or slightly higher than the top of the wall body. The height of the second row of stands is about 1.5 m lower than that of the first row of stands, and the height of the third row of stands is about 1.5 m lower than that of the second row of stands. The three rows of stands are arranged in a “ladder-type” manner.

[0047] If poles need to be extended, butt couplers must be used for connection. The butt couplers on the poles must be staggered. The joints of two adjacent poles should not be set in the same phase. The two adjacent joints of every other pole in the same phase should be staggered by a distance of not less than 500mm in the height direction. The distance from the center of each joint to the main node should not be greater than 1 / 3 of the step distance.

[0048] Sweeping rods: The support system must be equipped with longitudinal and transverse sweeping rods. The longitudinal sweeping rods are fixed to the uprights at a distance of no more than 200mm from the top of the bottom surface using right-angle fasteners. The transverse sweeping rods are fixed to the uprights immediately below the longitudinal sweeping rods using right-angle fasteners.

[0049] Longitudinal horizontal bars: Longitudinal horizontal bars are set inside the uprights and are no less than 3 spans in length. Longitudinal horizontal bars are connected by butt couplers or by lap joints. When using butt couplers, the butt couplers are staggered. The joints of two adjacent longitudinal horizontal bars cannot be set in the same span or at the same time. The horizontal distance between two adjacent joints in different spans or at different times is no less than 500mm. The distance from the center of each joint to the nearest main node is no more than 1 / 3 of the longitudinal spacing. When using lap joints, the lap length is no less than 1m. Three swivel couplers are set at equal intervals within the lap area for fixing. The distance from the edge of the end coupler cover plate to the end of the lapped longitudinal horizontal bar is no less than 100mm.

[0050] Horizontal bars: Horizontal bars must be installed at the main nodes, fastened with right-angle couplers and must not be removed. The center distance between the two right-angle couplers at the main node shall not exceed 150mm. As the main load-bearing component of the support system, the distance from the connection node between the horizontal bar and the vertical bar on the load-bearing side to the wall should be controlled between 200mm and 300mm.

[0051] Horizontal diagonal bracing: Within the same phase, horizontal diagonal bracing is installed. The upper end of the diagonal bracing is fixed to the upright on the wall side, and the lower end of the diagonal bracing is fixed to the upright on the far side, forming a "triangular" support. This is more conducive to transferring the stress of the formwork to the ground anchor steel bars, thus contributing to the safety and stability of the system.
