A plurality of said branches (2) are evenly spaced in groups and fixed circumferentially on said main rod (1), wherein the bending section one (201) of one group is welded at one end of the main rod (1), flush with the end of said main rod (1), the other group is welded on said main rod (1) at a certain distance, said bending section two (202) forms an acute angle (3) with the axis of said main rod (1), and the fixed part is in the shape of a barb. The vertical distance between the end of said bending section two (202) and the main rod axis is equal, which is convenient for standard production and avoids the jamming phenomenon when implanting said anchor hole (5).

[0040] As shown, Figure 2 A plurality of said anchors and said connecting rod (4) are crosswise perpendicular welded, forming an anchor group with the same space direction, said connecting rod (4) is selected from threaded steel section, the welding distance between two adjacent anchors is equal to the distance between two adjacent said anchor holes (5). As shown, Figure 4 The connecting rod (4) is welded at the upper middle position of the beam reinforcement cage, and the said anchor is vertically upward, the distance between the first anchor and the column edge control line is half the width of the wallboard, after pouring the column and beam, the exposed part of each anchor of the anchor group on the beam is not greater than the depth of the anchor hole (5) drilled on the wallboard.

[0041] Pre-treatment before wallboard formwork: Before formwork, consider that the side with a tenon of the first wallboard is close to the edge control line of the column during installation, and plan the inner and outer surfaces of the wallboard accordingly. One said anchor hole (5) is drilled at the top and bottom end of the wallboard, and the spatial position of the anchor hole (5) at the lower end of the wallboard corresponds to the anchor in the beam, and the depth is not less than the exposed part of the anchor in the beam after pouring. From the inner or outer surface, drill said exhaust hole (6) at an angle of 0°≤ included angle with horizontal line <90°, said exhaust hole (6) opens at the bottom end of said anchor hole (5), as shown in the structure. Figure 3 The exhaust hole (6) at the top end of the wallboard is used for exhaust, and the exhaust hole (6) at the bottom end of the wallboard is used for separate grouting.
