Detailed Description

The present invention will be described in further detail with reference to the following drawings and specific embodiments. The advantages and features of the present invention will become more fully apparent from the following description and appended claims. It should be noted that the drawings are in simplified form and are not to precise scale, and are provided for convenience and clarity in order to facilitate the description of the embodiments of the present invention.

Example 1

Referring to fig. 1 to 4, a technical solution of the outwardly inclined cast-in-place shear wall formwork tie system of this embodiment is as follows:

the utility model provides a basement outer wall post-cast strip assembled protection wall construction structures, include basement outer wall 200 and set up the post-cast strip 400 between basement outer wall 200, the middle part in the both sides of post-cast strip 400 is equipped with respectively along the stagnant water steel sheet 300 of its direction of height extension, be equipped with respectively in the both sides of stagnant water steel sheet 300 and cover the dense hole wire net 500 of establishing on the basement outer wall, still including the concrete precast slab 100 of shutoff in the post-cast strip outside, be equipped with waterproof retaining wall 600 in the outside of concrete precast slab 100, still be equipped with waterproof layer 800 between waterproof retaining wall 600 and concrete precast slab 100.
