Embodiment Construction
[0025] refer to Figure 1 to Figure 2 Further description will be made on the embodiment of the stereotyped composite formwork and its construction technology of the present invention.
[0026] A construction process for a stereotyped composite formwork for a shear wall at an expansion joint, including channel steel 1, steel pipe 2, plank, steel bar, release agent, double-sided adhesive, wall-penetrating screw 4, pull nut 51, fastening Nut 52, fastener 6, PVC casing 7, comprise following construction steps:
[0027] 1) Make a stereotyped combination template:
[0028] a. According to the size of the wall body 9 at the expansion joint, use wooden planks to form a formwork 3 of corresponding size, and initially fix the planks with nails; the planks are 18mm thick clad wood plywood commonly used on the construction site, and the joints are planed with a woodworking saw , to ensure that the patchwork is dense;
[0029] b. Arrange a number of steel pipes 2 in parallel on the spl...
