Summary of the invention

The utility model task provides a kind of wall attaching parts of novel building scaffold, reliable guarantee the scaffold construction safety in, also can reduce obstruction to greatest extent to each link of building operations, improve efficiency of construction.

The characteristic of the wall attaching parts of the design's building scaffold is: it is made up of keeper, bolt and supporting nut; Keeper is embedded in the body collar tie beam outside, building; There is elongated hole in its header board central authorities; Thereafter plate and header board and the pipe fitting between them are integrated, and the screw rod tail end is fixed in scaffold short transversal pipe end, screw rod bolt head and keeper header board pivot bush unit.

Has spring washer between nut and the screw rod bolt head.

What connect keeper header board and back plate is square pipe fitting.

The mode of installing and using of the design's wall attaching parts: 1, keeper is embedded in the body collar tie beam outside, building, and the header board of keeper is concordant with the outer side elevation of collar tie beam; 2,, again the screw rod tail end is fixed in an end of scaffold short transversal pipe with screw rod pack into successively spring washer, nut; 3, make screw rod bolt head insert header board central authorities' elongated hole and rotate 90 degree, screw nut again and pressing the keeper anter by spring washer, this moment, screw rod can not come off by self-align elongated hole, and the scaffold short transversal pipe of its connection is perpendicular to the building facade; 4, by existing building steel tube fastener short transversal pipe is fixed in the vertical steel pipe (or horizontal steel pipe of parallel building facade) of scaffold.As above then realized being fixedly connected of scaffold and building body.

The contrary dismounting that is this wall attaching parts by said process.

The good effect of the utility model: screw rod spare can be reused, and only keeper is an expendable part, obviously economical with materials; Keeper is embedded in the collar tie beam, and other parts all outside collar tie beam, do not hinder any middle operation construction, can not produce because of the scaffold factor and be interrupted construction and secondary reparation construction, promotes the smooth degree of constructing, and obviously practices thrift man-hour; Pre-buried keeper exposed area is little, in practical product, and 0.5 square decimeter of each junction exposed area less than, and building body metope post processing do not had difficulty, no negative effect; Parts are few, cooperate succinctly, and the reliable in structure when assembling is used, safety guarantee property obviously surmount present scaffold connecting mode in usefulness, and last top-down layering is removed also quite simple.
