Abstract
The utility model relates to a double-S-shaped steel band for anchoring. The utility model is suitable for support and protection of underground laneway in mines. Both ends of the same surface of a band body are made into a double-S shape, and through holes used for connecting anchor rods are arranged in the double-S shape. The utility model is manufactured in the way of brake forming and pressure hole punching. The S shape arranged on both ends of the utility model is contracted under the action of the deformation pressure at the existence of the deformation pressure. At this point, wall rock moves towards the passage space, the wall rock breaks and the volume of the wall rock is enlarged after the break. Simultaneously, because the integration of the steel band with the double-S shape is appressed with the wall rock, oversize deformation caused by the waste rock after the break can be restricted. The broken waste rock is tightly squeezed instead of falling. The supporting capacity of the wall rock is sufficiently exerted. The utility model has the advantages of large contact area with the wall rock, large flexibility, leakage prevention of the waste rock and supporting capacity of large deformation earth pressure. The utility model reaches the goal that self-support capacity of the wall rock is exerted.
Description
Affiliated technical field
The utility model relates to the two S steel band of model of a kind of tunnel anchoring, be about mine underworkings supporting steel band, especially big with the country rock contact area, flexible big, anti-leak-stopping cash, can support large deformation ground and press, the anchoring of performance country rock self-supporting ability is with two S steel band of model.
Background technology
At present, known Xishan coal electricity Co., Ltd " anchoring W steel band of model ", the patent No.: ZL00264256.5, this steel band is shaped on the reinforcing rib on outstanding belt body surface on belt body, with corresponding connection anchor pole than large through-hole, can change the belt body structure of loosing, it is shared to be suitable for many bars, and the entire combination supporting is strengthened.Though have certain flexibility, allow country rock to produce a certain amount of distortion, limit country rock again and produce excessive distortion, to give full play to the self-supporting ability of country rock.But, cause contact area little owing to have only the reinforcing rib on outstanding belt body surface to contact with country rock.After surrouding rock deformation produces the crack, make the country rock that breaks produce excessive deformation, cause anchor pole to get loose or produce that cash makes whole supporting inefficacy with Louing in the place of not contact.
Summary of the invention
The purpose of this utility model provides a kind of big, flexible big with the country rock contact area, prevents the leak-stopping cash, and can give full play to the two S steel band of model of anchoring of the self-supporting ability of country rock.
The technical scheme that its technical problem that solves the utility model adopts is: this anchoring is to make two S types at the same surperficial two ends of belt body with two S steel band of model, and the through hole that connects anchor pole is arranged in two S types.This pair of method manufacturing that the S steel band of model is brake forming and pressure punching.
The beneficial effects of the utility model are that owing to adopted such scheme, when rock deformation pressure, the S type at two S steel band of model two ends shrinks under the effect of rock deformation pressure.This moment, country rock moved to lane space, and country rock breaks, and the country rock volume after breaking increases.Simultaneously, thereby the spoil of being close to after the country rock restriction is broken owing to two S steel band of model integral body produces excessive distortion, and the spoil that breaks tightly is crowded together and does not collapse, and so just becomes structure by load, not only can support the pressure that oneself can also support overlying rock.That is to say the self-supporting ability of having given full play to country rock.Thereby reach with big, flexible big, the anti-leak-stopping cash of country rock contact area, press the purpose of performance country rock self-supporting ability with supporting large deformation.Only become two S types in the structure, and the through hole that connects anchor pole is arranged in two S types in the steel band bending two ends, simple in structure.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the elevation of the anchoring of the utility model embodiment with two S steel band of model.
Fig. 2 is the elevation of prior art anchoring with the W steel band of model.
1. basic steel bands among the figure, the 2. through hole of connection anchor pole, 3. two S types on outstanding belt body surface, the 4. reinforcing rib on outstanding belt body surface.
The specific embodiment
In the embodiment shown in fig. 1, basic steel band 1 same surperficial bending two ends becomes two S types 3 on outstanding belt body surface, and has in two S type and the joining through hole 2 of anchor pole, and this steel band is that the method for brake forming and pressure punching is made.During use, country rock is close on another surface of unparalleled S steel band of model.
Claims (2)
1, a kind of anchoring is made up of the hole of belt body and connection anchor pole with two S steel band of model, and it is characterized in that: the bending two ends on the same surface of steel band becomes two S types.
2, anchoring according to claim 1 is characterized in that: connect in the Kong Zaishuan S type of anchor pole with two S steel band of model.
