Description

A kind of mobile staying hook

Technical field

The utility model relates to a kind of ship building industry upper deck region hatch coaming steel mobile staying hook that is used in.

Background technology

The General provisions of Liftable type suspension scaffold.Scaffold is worked out by norm and is divided into three kinds: 1) comprehensive scaffold there is no actual pattern, if in building the peace construction, at same position, have multiple project need use scaffold, can use this scaffold project, just other scaffold installation project can not take place again.2) external scaffolding is the scaffold of external wall construction, and interior scaffold is that interior wall is working, but general civil construction, civil engineering can not be applied mechanically interior scaffold.3) highly not very too high, and the little place of load-bearing, single scaffold can be used.The construction of high-rise building if use scaffold, must be done safe accounting, because high-rise scaffold accident takes place time and again.But up till now for to also have to solve the hook problem of building movable footrest, promptly do not solve easy to use, safety, the well-set movable footrest of building is linked up with problem.So its structure awaits to improve.

Summary of the invention

Technical problem to be solved in the utility model is to provide a kind of movable footrest convenience, safety, sound construction and big hook of loading weight built at above-mentioned prior art present situation.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: this mobile staying hook, include Hook, it is characterized in that: described Hook is L-shaped, form by vertical edge and hook portion, described vertical edge is the steel tube body of hollow, the top of this vertical edge is provided with and hangs the hanging part, hook portion is positioned at the bottom of vertical edge, hook portion is made up of cross tube and sheer pole at least, one end of upper and lower cross bar is connected with vertical edge by welding with upper-lower position respectively, and the other end of upper and lower cross bar is welded to each other together with another vertical hollow steel tube that is provided with respectively.

As improvement, described cross tube and vertical edge be weld together mutual vertically.

Improve, described cross tube is that two steel pipes are close together mutually side by side again, and sheer pole and the position that hollow steel tube welds mutually are higher than the position of vertical edge bottom, and between the upper and lower cross bar setting of vertical compartment of terrain by some strut bars.

Improve, described strut bar can be preferably two again, the upper and lower side of these two strut bars respectively with the upper and lower cross bar weld together of correspondence position separately.

Improve, described cross tube and vertical edge weld liner have set square again.

Improve, the lateral surface of described vertical edge is welded with the reinforced plate of strengthening intensity again.

Improve, described extension hanging part is the steel plate piece that left part is provided with hook again, and the welded top of the bottom of this steel plate piece by welding and vertical edge is provided with on the steel plate piece and can be connected at screw with other object together.

Improve, the right-hand member of described steel plate piece is welded with back-up block again, and the top margin of this back-up block is a horizon, and the base of this back-up block is a hypotenuse.

Compared with prior art, it is big that advantage of the present utility model is to build movable footrest convenience, safety, sound construction and loading weight, under equal conditions builds the labour power contrast of foot rest; The labour power of building movable footrest descends 70%, take and execute long-pending about 30000～35000 sq ms of fixed type scaffold list deck, labour cost is taken and is executed 1 sq m and approximately need 40 fens clock times, now uses this mobile staying hook instead, takes to execute 1 sq m and only need the time about 10 minutes; Safety in the use can reach 100%.Economy under the equal conditions; Executed the fixed type scaffold and compared with taking originally, expense descends 80%, take and execute long-pending about 30000～35000 sq ms of fixed type scaffold list deck, about 400～600 yuans of every square meter of material price (down together), about 600～1000 yuan of the every sq m of labour cost, now use this mobile staying hook instead, the every sq m of the expense of materials used only needs 200～250 yuan, and the every sq m of labour cost only needs 300～450 yuan.
