Overwhelming majority project perimeter defense all adopts the shaped steel suspension scaffolding, adopts traditional mode of setting up can form interior of building shaped steel in negative and positive angular position and intersects more, and girder steel, pre-buried ring difficulty location, causes shaped steel to install complicated, constructional difficulties; Jog bit-type steel need different in size, the constructor in such project will carry out shaped steel to cut (normal section steel length is all 6m or 9m).This way not only increases constructing operation difficulty and operating time, and the shaped steel after being simultaneously cut can not use at other positions or sundry item, cause larger waste of material.
Utility model content
The purpose of this utility model is: for the defect of prior art, and provide a kind of tool-type cantilever steel girder, it is easy for installation, and structure is simple, firmly, is easy to construction, to overcome the deficiencies in the prior art.
The technical solution of the utility model
A kind of tool-type cantilever steel girder, comprise i iron, in i iron one end, gripper shoe is set and this gripper shoe perpendicular to i iron, the connecting hole corresponding with embedded hole position on external wall is set on the supporting plate, connect embedded hole and connecting hole by bolt one to realize i iron and be vertically fixed on external wall, i iron upper surface arranges backstay.
In aforesaid a kind of tool-type cantilever steel girder, arrange connecting rod at i iron soffit, directly over gripper shoe, arrange suspension ring, suspension ring are fixed in embedded hole by bolt two and backing plate, are connected between suspension ring with connecting rod by wire rope.
In aforesaid a kind of tool-type cantilever steel girder, the distance of described connecting rod and gripper shoe is the 2/3-3/4 of i iron total length.
Owing to have employed technique scheme, compared with prior art, run into negative and positive angular position shaped steel and intersect many in the utility model solution prior art in builder's jack i iron installation process, girder steel, pre-buried ring difficulty location, difficult problem installed by steel I-beam; The utility model effectively solves problems, and girder steel can be made can to install in any position; Can also save the installation cost of cantilever steel girder, decrease material usage, installation rate also improves greatly simultaneously, and guarantee the duration of a project not by the impact that cantilever steel girder is installed, the utility model structure is simple, easy to make, practical.
