Abstract
The utility model relates to a stone bolt device, comprising a stone bolt (1) and a cross arm (2); the other end of the stone bolt (1), which is far away from the screwed end, is a hook shape, and the minimum vertical distance from a short end (1.1) of the hook shape formed by the stone bolt (1) to a long end (1.2) of the hook shape is more than the diameter of the cross arm (2), and the stone bolt device can be easily installed.
Description
Technical field
The utility model uses when relating to a kind of built tunnel, house, communication tower is connected and fixed device, specifically is a kind of anchor bolt apparatus.
Background technique
Anchor bolt apparatus comprises stone bolt and cross-arm.At present, in our actual using process, stone bolt and cross-arm use as a whole set of, promptly earlier cross-arm are passed the dog hole of stone bolt, and cross-arm and stone bolt are put into pre-glove together then.But in the using process of our reality, because the reserved opening of some reservation thing is smaller, be difficult to stone bolt and cross-arm are put into pre-glove together, must earlier cross-arm be inserted, refill stone bolt then, but, the stone bolt of prior art holds the diameter of the minimum perpendicular distance d (being the opening length of hook) of the long end that constitutes hook-type less than cross-arm because constituting the weak point of hook-type, thereby in the limited space of pre-glove, be difficult in stone bolt is tangled cross-arm, so just the method that must adopt expansion to preset mouth is installed stone bolt, thereby has increased installation difficulty.In addition, also need sometimes, many lower margins are installed on a cross-arm, so just more increased installation difficulty according to actual conditions.
The model utility content
The technical problems to be solved in the utility model is to provide a kind of installation difficulty low stone bolt.
The technical solution of the utility model is, a kind of stone bolt is provided, comprise stone bolt and cross-arm, described stone bolt is a hook-type away from the other end of threaded end, and described stone bolt constitutes the weak point of hook-type and holds the diameter of the minimum perpendicular distance of the long end that constitutes hook-type greater than described cross-arm.
After adopting above structure, the utility model compared with prior art has the following advantages:
Because constituting the weak point of hook-type, the utility model stone bolt stone bolt holds the diameter (be the length of opening) of the minimum perpendicular distance of the long end that constitutes hook-type greater than described cross-arm, therefore can earlier cross-arm be inserted in the pre-glove easily, and then tangle cross-arm with stone bolt.In addition, according to actual conditions ground needs, many stone bolt can be installed on a cross-arm.Therefore, installation difficulty of the present utility model is low.
As improvement, the utility model hook-type stone bolt is circle hook-type stone bolt, thereby makes the easier cross-arm that tangles of stone bolt.
Description of drawings
Fig. 1 is the structural drawing of the utility model anchor bolt apparatus.
Fig. 2 is the plan view of the utility model anchor bolt apparatus.
Fig. 3 is the structural drawing of prior art anchor bolt apparatus.
Shown in the figure 1, stone bolt, 1.1, short end, 1.2, long end, 2, cross-arm, 3, apart from d.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1 and Figure 2, the utility model anchor bolt apparatus comprises stone bolt 1 and cross-arm 2, described stone bolt 1 is a hook-type away from the other end of threaded end, and the short end 1.1 that described stone bolt 1 constitutes hook-type arrives the diameter of the minimum perpendicular distance 3 of the long end 1.2 that constitutes hook-type greater than described cross-arm 2.Thereby stone bolt can tangle cross-arm 2 easily.
Described hook-type stone bolt 1 more helps stone bolt 1 and tangles cross-arm for circle hook-type stone bolt.
In the present embodiment, the long end 1.2 of stone bolt 1 is an elongated cylinder screw rod, short end is a stone bolt head 1.1, can earlier cross-arm 2 be inserted in the pre-glove during installation, tangling cross-arm with the opening of stone bolt head then gets final product, in addition, the utility model can increase cross-arm 2 length, thereby on cross-arm 2 many stone bolt 1 is installed.
Claims (2)
1, a kind of anchor bolt apparatus, comprise stone bolt (1) and cross-arm (2), it is characterized in that: described stone bolt (1) is a hook-type away from the other end of threaded end, and the short end (1.1) that described stone bolt (1) constitutes hook-type arrives the diameter of the minimum perpendicular distance (3) of the long end (1.2) that constitutes hook-type greater than described cross-arm (2).
2, anchor bolt apparatus according to claim 1 is characterized in that: described hook-type stone bolt (1) is circle hook-type stone bolt.
