Abstract
The invention discloses a critical edge and cave entrance protective device and a fixing method of the critical edge and cave entrance protective device. The critical edge and cave entrance protective device and the fixing method of the critical edge and cave entrance protective device comprise a steel pipe body. A protective steel pipe penetrates through the steel pipe body. A locking mechanism used for fixing the protective steel pipe is placed on one side of the middle of the steel pipe body, and comprises a fixing nut welded on the steel pipe body. A threaded hole of the fixing nut is communicated with a pipe hole of the steel pipe body. A locking bolt with a nut is placed in the threaded hole of the fixing nut. A screw is welded, relative to the other end of the locking mechanism, on the steel pipe body. The screw is placed perpendicular to the steel pipe body. A locking nut is placed at the end, away from the steel pipe body, of the screw. When in construction, the screw is inserted in a screw hole of a shear wall, and is locked by the locking nut. The critical edge and cave entrance protective device is simple in structure, convenient to fix, capable of being repeatedly used and low in cost.

By adopting technique scheme, during construction, screw rod is inserted in the screw rod hole of shear wall, lock by locking nut, simple in structure, convenient fixing can be reused, and cost is low.
The present invention further is set to: described screw rod is arranged in the middle part of the steel pipe body, and the screw rod center line overlaps with the center line of hold-down nut.By this setting, screw position arranges rationally, makes work of the present invention more reliable.
The present invention 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, works more reliable.
The present invention also further is set to: the diameter of described screw rod is 14mm.By this setting, screw size is reasonable in design, works more reliable.
The present invention 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, works more reliable.
The present invention has laterally and vertical two kinds of fixing meanss, and laterally fixing means is that protector laterally is fixed on shear wall screw rod hole, then passes horizontal protection steel pipe, fixes horizontal protection steel pipe; Vertical fixing means is that protector vertically is fixed on shear wall screw rod hole, then inserts vertical protection steel pipe, then adds horizontal case protection steel pipe, at last by laterally protecting steel pipe with fastener and vertical protection steel pipe is fixed.
Advantage of the present invention is: the present invention 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, then wear the protection steel pipe at the steel pipe body, to protect steel pipe and fix by a retaining mechanism is set on the steel pipe body, simple in structure, fixing reliable, can reuse, with low cost.
The invention will be further described below in conjunction with specification drawings and specific embodiments.
