Further, in the template notch processing, the template is customized according to the size factory; the thickness of the tetrafluoroethylene plate is 5mm, and the height of the tetrafluoroethylene plate is 240 mm; the center distance of the U-shaped notches is 200mm, and the length of the U-shaped notches is 55 mm; arranging a specially-assigned person at a project department for actually measuring the smoothness and the size; the panel size is examined with the box chi to the panelist feels to handle and examines the smoothness of template arc department, uses the sense of touch smooth as judging the basis.

Furthermore, in the template purchase, the group qualified suppliers are preferably selected by the group members, the products are complete in three certificates, edges and corners are protected in the transportation process, the upper cover is arranged below, the stress points are not less than three positions, and the damage to the materials is guaranteed.

Further, the assembling process of the bidirectional fastening bracket holder is as follows:

s1, ejecting a post-cast strip control line on the template according to the position required by the drawing;

s2, installing the lower bracket in place according to the position of a control line, and connecting the two sections of bracket brackets through socket joints;

s3, mounting a lower row of steel bars, and paying attention to the fact that the lower skin of the steel bars is slightly higher than that of the lower support;

s4, inserting a tetrafluoroethylene plate;

s5, mounting upper-row steel bars;

s6, mounting an upper bracket;

s7, adjusting a knob, and adjusting the width of the post-cast strip;

and S8, after the concrete pouring is finished, sequentially detaching the components from top to bottom, and cleaning the components for the next use.

The invention has the following technical effects: convenient operation, template reuse, low labor intensity and high efficiency.
