The invention discloses an anchoring device of a cantilever scaffold. The anchoring device comprises fastening parts, hanging frames, diagonal members and steel beams; the fastening pieces are fixedly connected to right-angled corners of walls of a building; two steel beams are respectively arranged on the outer sides of two adjacent walls of the building in parallel; one ends of the steel beams are connected to the fastening pieces, and the other ends are hung on the hanging frames; the hanging frames are hung on support steel beams perpendicularly inserted in the walls of the building and used for building the cantilever scaffold; one ends of the diagonal members are fixedly connected to the fastening pieces; and the other ends are fixedly connected to the walls of the building. The anchoring device uses lower support plates as support ends parallel to the building and with second clamping convex rib steel beams, uses upper pressing plates for limiting horizontal displacement of the support steel beams, and solves the difficulties of incapability of placing two steel beams in the corners of the building and the stability of erection points of vertical rods and the scaffold.
Description
Technical field：
The present invention relates to a kind of anchor of builder's jack.
Background technology：
Support steel beam is typically fixed on reinforced concrete girder slab by builder's jack using U-shaped reinforcing bar draw ring or anchor bolt
In structure, not less than 1.25 times of cantilever span, common practice has anchorage length at the corner post of framework and shear wall structure：
First, support steel beam passes through corner post, by the hole reserved on support steel beam longitudinal reinforcement is passed through, or
Longitudinal reinforcement is welded on support steel beam, the later stage cuts off the support steel beam that support steel beam is retained in column interior.The way
Disadvantage is to cause the loss and waste of support steel beam, all can be given in support steel beam using support steel beam perforate or reinforcement welding
Scaffold and the next certain potential safety hazard of this green tape of building structure.
2nd, support steel beam avoids corner post, and using oblique intersecting form, in building, corner sets up parallel with building
Girder steel installs requirement with the requirement and scaffold angle point for meeting vertical pole's span.The weak point of the way is angularly disposed
Support steel beam often collides with adjacent support steel beam, and the potential safety hazards such as anchorage length deficiency will be caused after blocking；And increase
If parallel girder steel the situation that cannot shelve or shelve off-axis occurs in intersection, bring certain tired to site operation
It is difficult.
