Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments. It should be noted that, in the present invention, the embodiments and features of the embodiments may be combined with each other without conflict. For convenience of description, the words "upper", "lower", "left" and "right" in the following description are used only to indicate the correspondence between the upper, lower, left and right directions of the drawings themselves, and do not limit the structure.
A concrete post-cast plate steel bar reserving device mainly comprises a groove 1, reserved plate steel bars 2, iron wire binding 3 and shear wall embedded steel bars 4. The notch of the groove 1 is flush with the shear wall template 5, namely the opening of the groove 1 is tightly attached to the shear wall template 5, so that the shear wall can be conveniently poured, the groove bottom of the groove extends into the pouring area of the shear wall, after pouring is completed, an opening area is formed at the groove 1, and the groove 1 is horizontally arranged in the length direction, namely transversely arranged.
