Description
Technical field
The utility model relates to building operations auxiliary security facility, is specifically related to a kind of hole, limit protector that faces.
Background technology
Stipulate according to " national construction safety check criteria " JGJ59-2011, do not build the floor periphery of enclosure wall, should adopt steel pipe or mao bamboon to set up the twice guard rail, existing project in construction adopts the steel pipe protection substantially, but how the steel pipe guard rail is fixed, how to do attractive in appearance is the problem that everybody studies always, what present stage often did is that the guard rail root is fixed on the concrete building plate with setscrew, need boring earlier because beating expands, and boring needs machinery and electricity consumption, cost height, construction is got up cumbersome, length consuming time causes a lot of units to be used inferior materials and turned out substandard goods, and has potential safety hazard.
Summary of the invention
At the deficiency that prior art exists, the purpose of this utility model is to provide a kind of simple in structure, with low cost, convenient fixing and can reusablely faces hole, limit protector.
For achieving the above object, the utility model provides following technical scheme: a kind of hole, limit protector that faces, comprise the steel pipe body, be equipped with the protection steel pipe in the steel pipe body, described steel pipe body middle part one side is provided with the retaining mechanism for the fixed protection steel pipe, described retaining mechanism comprises the hold-down nut that is welded on the steel pipe body, and the screw of described hold-down nut is communicated with the pore of steel pipe body, is provided with the lock bolt of band nut in the screw of described hold-down nut; Be welded with a screw rod on the steel pipe body with respect to the other end of retaining mechanism, described screw rod arranges with the steel pipe body is vertical, and screw rod deviates from the steel pipe body end and is provided with locking nut.
By adopting technique scheme, during construction screw rod is inserted in the screw rod hole of shear wall, by locking nut locking, simple in structure, convenient fixing can be reused, and cost is low.
The utility model further is set to: described screw rod is arranged on steel pipe body middle part, and the central lines of screw rod center line and hold-down nut.By this setting, screw position arranges rationally, makes the utility model work more reliable.
The utility model also further is set to: the diameter of described steel pipe body is 51mm, wall thickness 3mm.By this setting, the steel pipe body dimension is reasonable in design, and it is more reliable to work.
The utility model also further is set to: the diameter of described screw rod is 14mm.By this setting, screw size is reasonable in design, and it is more reliable to work.
The utility model also further is set to: the diameter of described protection steel pipe is 48mm, and wall thickness is 3mm.By this setting, the protection steel pipe sizes is reasonable in design, and it is more reliable to work.
The utility model has the advantages that: the utility model is by adopting steel pipe body welding screw rod, during construction screw rod is inserted in the screw rod hole of shear wall, by the locking nut tie down screw, wear the protection steel pipe at the steel pipe body then, to protect steel pipe and fix by a retaining mechanism is set at the steel pipe body, simple in structure, fixing reliable, can reuse, with low cost.
The utility model is described in further detail below in conjunction with specification drawings and specific embodiments.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
The specific embodiment
Referring to Fig. 1, a kind of hole, limit protector that faces that the utility model provides, comprise steel pipe body 1, be equipped with protection steel pipe 2 in the steel pipe body 1, described steel pipe body 1 middle part one side is provided with the retaining mechanism for fixed protection steel pipe 2, described retaining mechanism comprises the hold-down nut 3 that is welded on the steel pipe body 1, and the screw of described hold-down nut 3 is communicated with the pore of steel pipe body 1, is provided with the lock bolt 4 of band nut in the screw of described hold-down nut 3; Be welded with a screw rod 5 on the steel pipe body 1 with respect to the other end of retaining mechanism, described screw rod 5 and the 1 vertical setting of steel pipe body, and screw rod 5 deviates from steel pipe body 1 end and is provided with locking nut 51.
For making the utility model fixing more reliable, as preferably, the described screw rod 5 of present embodiment is arranged on steel pipe body 1 middle part, and the central lines of screw rod 5 center lines and hold-down nut 3.
As preferably, the diameter of described steel pipe body 1 is 51mm, wall thickness 3mm.The diameter of described screw rod 5 is 14mm.The diameter of described protection steel pipe 2 is 48mm, and wall thickness is 3mm.
During the actual use of the utility model, fixing means has crosswise fixed and vertically fixes two kinds,
Crosswise fixed: whole device lateral is fixed on the shear wall screw rod hole, being about to screw rod 5 laterally is located in the shear wall screw rod hole, be fixed by locking nut 51, on steel pipe body 1, laterally wear protection steel pipe 2 then, again by lock bolt 4 fixing i.e. mouths.
Vertical fixing: that whole device vertically is fixed on the shear wall screw rod hole, being about to screw rod 5 vertically is located in the shear wall screw rod hole, be fixed by locking nut 51, on steel pipe body 1, vertically wear protection steel pipe 2 then, fixing by lock bolt 4 again, add cross bar between adjacent two protectors, in position will protect steel pipe with fastener at last and fixedly connected with cross bar.
The utility model has reduced construction cost, has saved material, and the protector preparation method is simple, can freely dismantle during assembling and disassembling, and handled easily has improved the civilized construction operating efficiency greatly, has promoted enterprise's quality.
