Description
Technical field
The utility model relates to a kind of screw rod through walls, especially a kind of three-stage environmental protection water-proof bolt and dedicated assembly and disassembly set
Cylinder.
Background technique
Presently commercially available screw rod through walls is the externally threaded monoblock type screw rod of both ends band, is prevented when use on the set of the middle part of screw rod
Water cushion, both ends cover top cement plug, stopper, and wall is sliced off with gas cutting by wall part is exposed after pouring.It is this due to need by
The screw rod gas cutting for exposing wall part falls, and by wall sooting after not only rubber plug, stopper burn after gas cutting, causes wall unsightly,
And it is time-consuming and laborious, working efficiency is low, influences construction speed, wastes raw material, while also causing environmental pollution.Therefore, it designs
A kind of three-stage environmental protection water-proof bolt and dedicated assembly and disassembly sleeve without gas cutting, is the current technical issues that need to address.
Summary of the invention
The technical problem to be solved by the utility model is to provide a kind of three-stage environmental protection water-proof bolt without gas cutting and
Dedicated assembly and disassembly sleeve.
The technical scheme in the invention for solving the technical problem is:
Three-stage environmental protection water-proof bolt is made of I, two screw rod II of screw rod, collision mat, nut and mountain type card, screw rod I
There is external screw thread at both ends and middle part is polished rod, length≤wall thickness of screw rod I, one end band external screw thread other end band of screw rod II
The blind screw hole of blind screw hole, screw rod II is matched with the external screw thread of screw rod I, the externally threaded length and spiral shell at I both ends of screw rod
The depth of the blind screw hole of bar II matches, and two screw rods II distinguish spinning at the both ends of screw rod I, and collision mat is sleeved on screw rod I
Intermediate light bar segment on；Screw rod II is stepped stem, and the diameter with external thread section is less than the diameter with blind screw hole section,
There is outward flange in the end with blind screw hole section of screw rod II, is set with conical plastics in the band blind screw hole section of screw rod II
Set is equipped with outer-hexagonal section in the band blind screw hole section of screw rod II.
As a kind of technical solution (three-stage environmental protection water-proof bolt) of the utility model, screw rod II is chromium plating screw rod.Spiral shell
Bar II is reusable, and chromium plating is for antirust.
The dedicated assembly and disassembly sleeve of three-stage environmental protection water-proof bolt, including sleeve body, on the inner wall of one end of sleeve body
There is square hole, the Hexagon hole on the inner wall of the other end of sleeve body, square hole size is matched with the square toes size of electric wrench.
As a kind of technical solution (the dedicated assembly and disassembly sleeve of three-stage environmental protection water-proof bolt) of the utility model, in square hole section
There is camber annular groove, has on camber annular groove for extending radially through hole with short round steel manual teardown screw rod II.
Compared with prior art, since the utility model waits for directly unloading screw rod II down after wall pours,
Not only time saving and energy saving, work efficiency is high, and is not in the phenomenon that gas cutting screw rod is by wall sooting, belongs to environmentally friendly production
Product.
