Stair step template supporting device provided with shear wall at two sides and supporting method

Abstract

The invention discloses a stair step template supporting device provided with a shear wall at two sides and a supporting method. Existing problems of a current template that the structure size deviation of a stair step is oversize and a construction procedure is complicated are solved. The stair step template supporting device comprises a left shear wall (10), a right shear wall (11) and a lower-layer stair step (1). The top surface of an upper-layer stair bottom plate template (4) is provided with a support sleeve (17). Transverse horizontal bracing steel pipes (9) are alternately between theleft shear wall (10) and the right shear wall (11). Slantwise bracing steel pipes (8) are alternately welded on the transverse horizontal bracing steel pipes (9). Step tooth-shaped steel bars (7) arewelded on the slantwise bracing steel pipes (8). The step tooth-shaped steel bars (7) are provided with a support rod (16). The support rod (16) is actively sheathed in the support sleeve (17). A step template (12) is inserted on the step tooth-shaped steel bars (7). The stair step template supporting device is capable of improving the manufacturing quality of the stair step.

Description

technical field [0001] The invention relates to a high-rise staircase formwork support device, in particular to a stair formwork support device and a support method with more standard floors in a shear wall structure scissors staircase. Background technique [0002] There are two forms of stair steps in general shear wall structure buildings, one is stairs with shear walls on one side of the steps, the other is stairs with shear walls on both sides of the steps; The construction process of the stair steps of the force wall is: on the stairs after the concrete strength of the next stair meets the requirements for supporting the upper frame body, set up the stair formwork support of the upper floor, and then support the bottom plate formwork of the stairs of this floor, and bind the stairs Reinforcement, according to the elevation and the size of the steps, the steps of the stairs are evenly separated, and the step formwork is independently supported. A steel pipe is crimped o...
