The width of the U-shaped clamping groove is equal to the thickness of the ladder step template, and the width of the inverted U-shaped rectangular clamping groove is equal to the thickness of the rectangular positioning block.
A combined dismantling method for an inserting and connecting combined type cast-in-place stair template system is characterized by comprising the following steps:
the method comprises the following steps that firstly, cuboid-shaped positioning blocks are arranged on the inner side surface of a stair inner side template at equal intervals according to stair steps, U-shaped clamping grooves are arranged on a stair outer side template at equal intervals according to the stair steps, the stair inner side template, the stair outer side template and a stair bottom template are combined and fixed together respectively, and the cuboid-shaped positioning blocks and the U-shaped clamping grooves are arranged correspondingly;
secondly, inserting the outer side end of the stair step template into a U-shaped clamping groove in the stair outer side template from top to bottom, and clamping the inner side end of the stair step template on a rectangular positioning block which is arranged on the inner side surface of the stair inner side template and corresponds to the U-shaped clamping groove through an inverted U-shaped rectangular clamping groove on the inner side end of the stair step template;
and thirdly, pouring stair concrete, after the concrete is solidified, upwards pulling the stair step template to enable the stair step template to be separated from the U-shaped clamping groove and the rectangular positioning block, and then sequentially removing the stair outer side template, the stair bottom template and the stair inner side template.
The construction process is simple to operate, the templates are convenient to install and disassemble, the template plates on the inner side and the outer side are subjected to lofting grooving in advance and positioning block installation, the step template plates are not required to be calibrated when being installed, the templates are not easy to damage after the templates are disassembled, the box-shaped step template can be repeatedly recycled, the construction speed of workers is greatly improved, the tenon-and-mortise type structure is adopted to ensure the stability of the step template, the forming quality of the step plate is improved, and the method can be widely applied to the erection construction of the cast-in-place concrete stair template.
