Part and protective sleeve phase attaching；Cooperate to regulate the length that adjusting rod stretches in protective sleeve by fixture and adjusting rod
Degree, and protective sleeve is fixedly connected with the test specimen to be measured being socketed in protective sleeve.
In one embodiment: described adjusting rod is screw rod, described fixture is nut.
In one embodiment: described some through holes height on protective sleeve is identical.
In one embodiment: described through hole is three, described positioning component is three.
In one embodiment: the external diameter of described protective sleeve is 65～75mm, internal diameter is 55～65mm, height be 145～
155mm。
In one embodiment: described through hole is arranged at protective sleeve distance upper port 45～55mm.
In one embodiment: described adjusting rod a diameter of 8～12mm, a length of 95～105mm.
In one embodiment: described protective sleeve is that metal is made.
The technical program is compared with background technology, and it has the advantage that
Safety device for steel concrete supporting tension test of the present utility model can be stretched into by adjusting screw rod
Length in protective sleeve so that it is fix with test specimen to be measured and test specimen to be measured is protected in protective sleeve, it is to avoid may go out
The risk that existing joint explosion fragment launches, prevents from testing crew is caused personal injury.This utility model is applicable to various rule
Lattice steel concrete supporting tension test security protection, material is simple, and Stability Analysis of Structures is easy to operate, low cost.
Accompanying drawing explanation
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings.

Detailed description of the invention
Content of the present utility model is illustrated below by embodiment:
In description of the present utility model, it is to be understood that term " on ", D score, "front", "rear", "left", "right",
Orientation or the position relationship of the instruction such as " horizontal ", " erecting ", " top ", " end ", " interior ", " outward " are based on shown in the axonometric chart in accompanying drawing
Orientation or position relationship, be for only for ease of and describe this utility model and simplify description rather than instruction or the dress of hint indication
Put or element must have specific orientation, with specific azimuth configuration and operation, therefore it is not intended that to this utility model
Restriction.
A kind of safety device for steel concrete supporting tension test, the protective jacket made including high duty metal
Cylinder 1 and three positioning components；Cylindrically, external diameter is 70mm to this protective sleeve 1, and internal diameter is 60mm, and height is 150mm；Anti-
On pretective sleeve pipe 1, at its upper port 50mm of distance, circumference uniform intervals is provided with three circular through holes 2；Described positioning component includes
Adjusting rod and fixture, among the present embodiment, adjusting rod is screw rod 3, and fixture is nut 4；This screw rod 3 diameter 8～10mm, long
Degree is 100mm, and screw rod 3 diameter is adaptive with through hole 2 size, and screw rod 3 is stretched in through hole 2 by protective sleeve 1 outside to inside, and by setting
Nut 4 outside protective sleeve 1 and protective sleeve 1 phase attaching, can be stretched into the adjusting screw rod 3 that coordinates of screw rod 3 by nut 4
Length in protective sleeve 1, it is achieved freely stretching of screw rod 3, thus by protective sleeve 1 be socketed in treating in protective sleeve 1
Test block is fixedly connected, and makes test specimen to be measured be protected.
This utility model onsite application mode is as follows:
Before steel concrete supporting tension test, it is only necessary to by rotating three screw rods 3 on metal protection sleeve 1 top, regulation
Screw rod 3 stretches into the length in protective sleeve 1, is then inserted in from the upper end of steel concrete supporting test specimen by this safety device,
Adjusting screw rod 3 again, make the junction of three screw rod 3 contacts joint at steel concrete supporting test specimen and reinforcing bar, tightening nuts 4
