Abstract
The utility mode discloses an anchor-fixing device, which includes an anchor bar, a fixed sleeve as well as connections. The fixed sleeve includes a cylindrical section and an expansion section. The conical bottom of the expansion section facing to the anchor bar is mounted on the anchor bar; the expansion section is processed with a plurality of gaps evenly distributed along the axis; the two adjacent gaps form an expansion slice; the connecting component can is formed by pouring the solidified molding liquid into an installing hole after the fixed sleeve expends. During application, the expansion section of the fixed sleeve of the utility model expands under an external force so as to clamp the conical bottom of the anchor bar and then pour the solidified molding liquid into the installing hole, which is solidified as a connecting component. The anchor fixing device of the utility model is simple in structure, which can reach a good anchor effect under the conditions of both shallower and deeper instillations. After the end of the anchor bar is connected with a connecting joint, the anchor bar can easily connected with steel rib or other connecting components in the mode of threading or welding.
Description
Technical field
The utility model relates to a kind of anchor.
Background technique
Existing crab-bolt normally utilizes the frictional force that produces between expansion sleeve and the mounting hole hole wall to realize anchoring, and the size of its anchor force and the length of expansion sleeve is closely related.When mounting hole was more shallow, expansion sleeve was shorter, and the anchor force that provides is less, was difficult to the anchoring effect that reaches good; When mounting hole was dark, enough big for making anchor force, required expansion sleeve was longer, if expansion sleeve is made an integral body, will be difficult to be inserted in the mounting hole, especially running under the crooked situation of mounting hole existence, can't install at all.If dwindle its external diameter for expansion sleeve being inserted in the tube, will cause rock bolt shank in mounting hole, to occur radially rocking, and then influence the anchoring effect that crab-bolt is treated the anchor object.Therefore, existing crab-bolt is unsuitable for using under the darker situation of mounting hole.
The model utility content
At the problem that existing crab-bolt exists, the purpose of this utility model provides a kind of anchor that can both reach good anchoring effect under any installation conditions.
For achieving the above object, the utility model anchor comprises: anchor pole, fixed muffle and connecting sleeve; Described fixed muffle comprises cylindrical section and spreading section, and the spreading section is sleeved on the anchor pole towards the anchor pole tapered bottom end, processes several on the described spreading section along its axial uniform breach, forms a spreading sheet between adjacent two breach; Described connecting sleeve is the fluid of curable moulding to be poured in the mounting hole to solidify to form behind the fixed muffle section of rising spreading.
Further, described connecting sleeve is solidified by resin fluid and forms.
Further, described connecting sleeve is solidified by cement slurry and forms.
Further, described anchor pole end also has jointing, and this joint one end is by welding or linking to each other with anchor pole threadably, and its other end links to each other with reinforcing bar or other members as anchor point.
The spreading section of the utility model fixed muffle is spreading under external force, and the anchor pole tapered bottom end is fixed in mounting hole, and the fluid with curable moulding pours into mounting hole again, and treats that it is frozen into connecting sleeve.The utility model anchor is simple in structure, no matter can both reach good anchoring effect under more shallow still darker installation conditions.After the anchor pole end is provided with jointing, can link to each other with screw thread or welding manner with reinforcing bar or other links easily.
Description of drawings
Accompanying drawing is depicted as anchor structural representation described in the utility model.
Embodiment
As shown in the figure, this anchor comprises: anchor pole 1, fixed muffle and connecting sleeve 2; Fixed muffle comprises top cylindrical section 3 and bottom spreading section 4, processes several on the spreading section 4 along its axial uniform breach, forms a spreading sheet between adjacent two breach; Connecting sleeve 2 behind fixed muffle spreading section 4 spreadings with resin fluid or grout in mounting hole and solidify to form; Jointing 5 is fixed on anchor pole 1 end threadably, also can be welded to connect with anchor pole.
During use, earlier anchor pole 1 and fixed muffle are put into the bottom and be the mounting hole of taper, the spreading section 4 that makes fixed muffle is spreading under pressure, with anchor pole 1 bottom tapered end fixing at the bottom of the cone shape hole; Pour into resin fluid or cement slurry from the aperture is installed again, make its solidifying around rock bolt shank, form connecting sleeve 2; With anchor pole fixing after, need the reinforcing bar that connects by being welded to connect on jointing, when the member that connects when needs is screw, also can be on jointing thread mill drilling, connected member is linked to each other with jointing threadably.Because of connecting sleeve 2 is fastened on around the rock bolt shank, thereby can guarantees that rock bolt shank does not postback to give birth to and radially rock in mounting hole, thereby reach good anchoring effect.
