Abstract
The utility model discloses a bolting yield component capable of improving the deformation resistant ability of a bolting, which is of a lantern-shaped shell with an upper orifice and a lower orifice, wherein the diameter of the orifice is matched with the diameter of the bolting. The utility model is mainly used for a bolting in an underground roadway, can reduce the impact of the change in stress on the bolting, so that the bolting always keeps the support strength for the roof.
Description
Technical field
The utility model relates to the support of underground tunnel material, relates in particular to support anchor rod.
Background technology
At present, the support of underground tunnel anchor pole all is that anchor bar body is anchored in the boring, tightens up at hole external application nut pallet.Its deficiency is: when increase was pressed on roadway deformation ground, anchor pole can be out of shape even break, and loses anchored force.
Summary of the invention
The utility model is in order to solve the problem of anchor stress distortion, provides a kind of anchor pole allow the pressure member.This member can be controlled anchor stress and change, and also can improve the ability of anchor pole opposing STRESS VARIATION and control bolt deformation, controls bolt deformation within certain pressure limit, makes anchor pole remain supporting intensity to top board.
For addressing the above problem, the technical scheme that the utility model is taked is: it is a bird-caging housing that has lower nozzle, and the diameter of the mouth of pipe matches with bolt diameter.
Described bird-caging is a general designation, comprises that section is the bird-caging of circle, oblong and flat ellipse.
Allow the pressure scope for what adapt to anchor pole, described housing is preferably spherical shell.
During use, it is installed between the damping nut and anchor pole pallet of anchor pole, during roadway deformation, allows and press member at first to be out of shape, allow after the pressure scope anchor pole redeformation exceeding.
The beneficial effects of the utility model are, can improve the non-deformability of anchor pole greatly, and reduce the impact of STRESS VARIATION to anchor pole, make anchor pole remain supporting intensity to top board.
Description of drawings
Fig. 1 is the schematic perspective view of the utility model embodiment one;
Fig. 2 is the sectional view of Fig. 1;
Fig. 3 is the schematic perspective view of the utility model embodiment two;
Fig. 4 is the schematic perspective view of the utility model embodiment three.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further specified.
Embodiment one, and as depicted in figs. 1 and 2, it is a spherical shell that has lower nozzle, and the diameter of the mouth of pipe matches with bolt diameter.
Embodiment two, and as shown in Figure 3, it is a prolate ellipsoid shape housing that has lower nozzle, and the diameter of the mouth of pipe matches with bolt diameter.
Embodiment three, and as shown in Figure 4, it is an oblate ellipsoid shape housing that has lower nozzle, and the diameter of the mouth of pipe matches with bolt diameter.
Add man-hour, intercept one section seamless steel pipe, the internal diameter of seamless steel pipe matches with bolt diameter, and the housing that forms as shown in the figure through forging forming, heat treatment gets final product then.
Claims (2)
1. an anchor pole allows the pressure member, it is characterized in that it is a bird-caging housing that has lower nozzle, and the diameter of the mouth of pipe matches with bolt diameter.
2. anchor pole as claimed in claim 1 allows the pressure member, it is characterized in that, described housing is spherical.
