Abstract
The utility model discloses a kind of metal resin anchoring rod body, is process left-handed coarse thread steep-pitch thread at the anterior anchoring section of metallic rod body, fastening section of rear portion processing dextrorotation coarse thread steep-pitch thread, and rear threads can direct assembling nut; Pitch and the rib of the utility model screw thread are tall and big, larger than the anchored force of existing thread steel type resin anchor, and this metallic rod body front portion is left hand thread, and rear portion is right-handed thread, can meet resin agitating and existing facility installation needs simultaneously, realize Fast Installation; The utility model is applicable to anchoring support metallic rod body in underground construction, mine working, construction of tunnel.
Description
Technical field
The utility model relates to the anchor pole in a kind of underground construction, mine working, construction of tunnel, particularly relates to a kind of metal resin anchoring rod body.
Background technology
In the geotechnical engineerings such as underground construction, mine working, tunnel, water conservancy culvert and side slope protection, for preventing stratum deformation, subside or unstability and need formation to reinforce, the main support technology of the one adopted is bolt support, mostly use metal-resin anchor pole at present, it is mainly divided into two kinds, one is that left-handed nothing indulges rib resin anchor, and another kind is the strong full thread resin anchors such as dextrorotation, all there is different problems during these two kinds of resin anchors use at the scene.The first left-handed nothing indulges rib resin anchor, and its body of rod makes by without vertical rib screw-thread steel, and screw-thread steel rib height is less, and resin agitating is insufficient, thus has a strong impact on the anchored force of anchor pole; Greatly, it is insufficient to add resin agitating, causes anchored force also unreliable for the strong full thread resin anchor body of rod such as the second dextrorotation and nut screw connection gap.
Summary of the invention
The purpose of this utility model is to overcome the defect existed in prior art, provide a kind of install fast and reliable, anchored force large, can meet a kind of metal resin anchoring rod body that clamp nut needs installed by resin agitating and existing facility simultaneously.
The purpose of this utility model is achieved through the following technical solutions:
A kind of metal resin anchoring rod body, it is made up of the left-handed coarse thread steep-pitch thread 2 on the body of rod 1 and the body of rod 1, dextrorotation coarse thread steep-pitch thread 3, described left-handed coarse thread steep-pitch thread 2 is positioned at the anterior anchoring section of the described body of rod 1, and described dextrorotation coarse thread steep-pitch thread 3 is positioned at fastening section of the rear portion of the described body of rod 1.
The utility model has the following advantages:
Pitch and the rib of screw thread described in the utility model are tall and big, larger than the anchored force of existing thread steel type resin anchor, and this body of rod front portion is left hand thread, rear portion is right-handed thread, can direct assembling nut, resin agitating can be met and needs installed by existing facility simultaneously, realize Fast Installation.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Detailed description of the invention
Below in conjunction with accompanying drawing, by specific embodiment, technical solutions of the utility model are described further.
As shown in Figure 1, Fig. 1 is the utility model structural representation.A kind of metal resin anchoring rod body, it is made up of the left-handed coarse thread steep-pitch thread 2 on the body of rod 1 and the body of rod 1, dextrorotation coarse thread steep-pitch thread 3, described left-handed coarse thread steep-pitch thread 2 is positioned at the anterior anchoring section of the described body of rod 1, and described dextrorotation coarse thread steep-pitch thread 3 is positioned at fastening section of the rear portion of the described body of rod 1.
Pitch and the rib of screw thread described in the utility model are tall and big, larger than the anchored force of existing thread steel type resin anchor, and this body of rod front portion is left hand thread, rear portion is right-handed thread, can direct assembling nut, resin agitating can be met and needs installed by existing facility simultaneously, realize Fast Installation.
Although the utility model with preferred embodiment openly as above; but they are not for limiting the utility model, anyly haveing the knack of this those skilled in the art, not departing from the spirit and scope of the utility model; can make various changes or retouch from working as, but same within protection domain of the present utility model.
Claims (1)
