The scaffold main body 100 comprises a horizontal rod and a vertical upright rod, wherein the horizontal rod is horizontally arranged, the vertical upright rod is vertically arranged, the scaffold main body 100 is arranged on the outer side of a wall body of a building structure, and the bottom of the scaffold main body is supported on the ground or a cantilever beam. The tie rod assembly 200 includes a plurality of tie rods 210. The tie rods 210 may be rods (e.g., round tubes) of the same gauge as the scaffold structure 100 is constructed. One end of the tie rod 210 is connected to the structural beam 400 (including the cross beam and the side beam) of the lower layer of the construction layer 300 of the building structure, and the other end is connected to the scaffold body 100 to apply a pulling force (horizontal component) toward the wall and an upward supporting force (vertical component) to the scaffold body 100. And the distance H1 between the joint of the pull rod 210 and the scaffold main body 100 and the top of the scaffold main body 100 is not more than 400mm, thereby meeting the construction requirement. Since the structural beam 400 spans between the structural columns such that the number of tie rods 210 in the tie rod assembly 200 is not affected by the spacing of the structural columns, a plurality of tie rods 210 can be disposed between adjacent structural columns to improve the firmness of the scaffold, thereby improving construction safety.

In addition, in some embodiments, the scaffold further includes a clasping post, one end of which is connected to the structural post and the other end of which is connected to the scaffold body 100, to improve the firmness of the scaffold.

In general, in the construction process, after the tie rod 210 is removed, the embedded part 220 is cut off to be flush with the upper surface of the structural beam 400, and mortar is refilled for blocking, so that in order to avoid water on the upper surface of the structural beam 400 from penetrating to the lower surface of the structural beam 400 along a gap of the embedded part 220 at a concrete joint, the hidden danger of water seepage of a floor occurs. In some embodiments, the distance H3 between the bottom of the embedment 220 and the bottom of the structural beam 400 is not less than 100mm (as shown in fig. 2) to avoid floor infiltration.

In some embodiments, the tie rod assembly 200 includes a plurality of embedments 220, and the number of embedments 220 is greater than the number of tie rods 210. Therefore, in the construction process, the connection position of the pull rod 210 can be selected according to actual requirements, the situation that the connection of the pull rod 210 is blocked by other structures in the construction process is avoided, and the practicability is improved. And can make scaffold main part 100 have more stress points optional, when putting up to select suitable stress point, make scaffold main part 100 atress more reasonable, improve scaffold main part 100's fastness.

In some embodiments, the pull rod 210 is detachably connected with the embedded part 220, so as to facilitate connection of the embedded part 220 with the pull rod 210 and facilitate secondary use of the pull rod 210. In addition, the connection point of the tie rod 210 to the structural beam 400 is easily replaced during construction.
