踏步不同于传统木模，踏步面采用铝合金模板封闭，边浇筑边封闭，在底部留置

The step is different from the traditional wooden mold. The step surface is closed with aluminum alloy formwork, closed while pouring, and the observation port is left at the bottom to ensure the integrity and size of the stairs. <br>(3) Door and window openings, reserved opening <br>floor slab reserved holes, and wall reserved holes: Because the aluminum alloy reserved hole frames are all tool-type and stereotyped, they are consistent with the upper and lower of the conventional floor or the size of the wall openings It is difficult to remove during the demolition of the reserved frame, and it is easy to damage the corners of the reserved hole. The existing floor adopts the method that the slope is large on the bottom and the wall is small on the outside and the inside is small

Step is different from the traditional wood mold, step surface using aluminum alloy template closed, side pouring edge closed, in the bottom of the retention observation port, to ensure that the integrity of the stairs and the same size.<br>(3) Doors and windows and reserved holes<br>Floor reserved holes, wall reserved holes: because aluminum alloy reserved hole frame stool is tool-type, stereotyped, according to the regular floor up and down small or wall hole inside and outside the size, in the reservation box demolition process is difficult to remove, and it is easy to destroy the corner of the reserved hole, the floor is now using the slope of large and small, the wall using the slope outside the large and small approach

The step is different from the traditional wooden formwork. The step surface is sealed with aluminum alloy formwork, pouring and sealing at the same time. An observation port is reserved at the bottom to ensure the integrity and size of the stairs.<br>(3) Door and window openings and reserved openings<br>Floor reserved holes and wall reserved holes: as the aluminum alloy reserved holes and frames are all tool type and stereotyped, it is difficult to remove the reserved frames according to the same size of the upper and lower floors or the internal and external sizes of the wall openings, and it is easy to damage the edges and corners of the reserved holes. Now the floor adopts the method of large upper and small lower inclined planes, and the wall adopts the method of large outer and small inner inclined planes<br>
