Abstract
The utility relates to a support part of a coal mine tunnel, in particular to a support steel strip for assembled anchor bar, which solves the problems of an existing support steel strip for assembled anchor bar that the supporting strength is comparatively poor, and the strip is easily deformed during the use. The support steel strip for assembled anchor bar is characterized in that three projections whose length is equal to that of the metal strip are arranged on both sides of the central line of the flat steel strip along the central line, and holes are arranged on the projections along the central line. The projections are added along the central line based on the existing support steel strip for assembled anchor bar, the supporting strength and the deformation resisting ability of the support steel strip are added, and the service life of the support steel strip is improved.
Description
Technical field
The utility model relates to the colliery tunnel support parts, is specially assembled bolt supporting steel band.
Background technology
Having listed the existing assembled bolt supporting steel band of national coal industry standard in, is to be respectively equipped with the projection isometric with steel band in dull and stereotyped steel band center line both sides, along steel band center line uniform porose (as shown in Figure 1).The similar letter of the cross sectional shape of this existing steel band " W " therefore is called mining W steel band of model in the national coal industry standard.During use, anchor pole inserts the hole on the supporting steel band and the nut of screwing on respectively.Existing assembled bolt only is provided with projection in the center line both sides with the supporting steel band, and its support strength is relatively poor relatively, and steel band is easy deformation in use, influences application life.
Summary of the invention
The utility model is relatively poor relatively with supporting steel band support strength in order to solve existing assembled bolt, and the problem of easy deformation in the use provides a kind of improved assembled bolt supporting steel band.
The utility model is to adopt following technical scheme to realize: assembled bolt supporting steel band is to be provided with three projectioies isometric with steel band in the center line both sides of dull and stereotyped steel band and along center line, along uniform porose on the projection of center line.Anchor pole inserts the hole on the steel band respectively and screws on nut and form assembled bolt during use.
The utility model has been set up the projection along center line on the basis of existing assembled bolt with the supporting steel band, increased the support strength and the non-deformability of supporting steel band, has improved the application life of supporting steel band.
Description of drawings
Fig. 1 is the schematic cross-section of existing assembled bolt with the supporting steel band;
Fig. 2 is the structural representation of assembled bolt described in the utility model with the supporting steel band;
Fig. 3 is the schematic cross-section of Fig. 2;
The specific embodiment
Assembled bolt supporting steel band is to be provided with three projectioies 1 isometric with steel band in the center line both sides of dull and stereotyped steel band and along center line, along on the projection of center line uniform porose 2.During use, determine the length of supporting steel band as required, anchor pole inserts the hole on the steel band respectively and screws on nut and form assembled bolt.
