Abstract
The utility model relates to a novel tail fastening device for a thread anchor rod. The novel tail fastening device is characterized by comprising a nut and a tray, wherein the nut sleeves the threaded anchor rod and is inserted into a through hole at the center of the tray. The inner surface of the nut is of a threaded structure for achieving threaded connection with the threaded anchor rod; the appearance of the lower section of the nut is of a hexagonal prism shape, which is convenient to fasten by rotating, and the appearance of the upper section of the same is in the shape of a cone which achieves wedge-shaped conical surface fastening with the conical inner surface of the through hole at the center of the tray. The inner surface of the through hole at the center of the tray is conical in shape; the appearance of the tray is in the shape of an inverted cone with a small end down and a large end up, and the outer plane of the tray is tightly attached to the periphery of an anchor eye in rock. Threaded connection between the nut and the threaded anchor rod can be achieved by only rotating the nut, and the nut is fastened with the wedge-shaped conical surface of the tray, so that the three components are closely connected together. The tail fastening device for the threaded anchor rod is simple in structure, convenient to operate, low in cost and strong in practicability.
Description
Technical field
The present utility model relates in safety support engineering field, a kind of Novel threaded anchor pole afterbody fastener adopting while taking threaded anchor rod supporting.Take the threaded anchor rod supporting of this threaded anchor rod afterbody fastener, can be widely used in mining, the support engineering in tunnel in the old work progress such as engineered of highway, railway, water conservancy, municipal engineering, danger, tunnel, ramp, and the reliability and the safety that significantly improve support engineering, for safety in production provides reliable guarantee.
Background technology
Bolt support is a kind of its support reinforcement mode adopting in the underground chamber constructions such as the earth's surface engineerings such as side slope, ground deep foundation ditch and tunnel, stope.Make roofbolt with metalwork, wooden part, polymer member or other materials, squeeze in the pre-drilled hole of earth's surface rock mass or chamber surrounding rock body, utilize the special tectonic of its body of rod and afterbody supporting plate, and the cementation of Anchor Agent combines country rock and rock mass stability and produce suspension effectiveness, compound beam effect, reinforcing effect, to reach the object of supporting.Have that cost is low, supporting effect good, easy and simple to handle, use flexibly, take the advantages such as construction area is little.
The anchoring effect of bolt support depends on the load resistant power of anchor rod body and the load resistant power of anchor pole afterbody fastener.Wherein the current general way of anchor pole afterbody fastener is that nut, tray combination are fastening.But nut external surface is wedge shape taper seat, the inner surface of pallet via hole is prismatic face of cylinder.There is following defect or deficiency in secure fit between the two:
Nut external surface and pallet center are crossed and between internal surface of hole, can not be realized face-face and entirely contact, and are only line contacts, and both contact area areas are little, and stress is concentrated, and easily causes nut or pallet and produces damage inactivation because stress concentrates.
Summary of the invention
The purpose of the present utility model is to invent the threaded anchor rod afterbody fastener of wedge shape taper seat close contact between a kind of nut (1) and pallet (2), and this device can avoid nut (1) or pallet (2) to produce damage inactivation because stress concentrates.Fundamental technics principle of the present utility model is simple in structure, compact, easy to operate, safe and reliable, cheap, is convenient to promote the use of.
According to the basic principle of foregoing invention, the present utility model is taked following technical solution: threaded anchor rod afterbody fastener is made up of nut (1) and pallet (2), and nut (1) is worn threaded anchor rod (3) and pallet (2) center via hole.Between nut (1) and threaded anchor rod (3), adopt and be threaded.Nut (1) external surface and pallet (2) center cross that between internal surface of hole, to take taper seat wedge shape to contact fastening.Pallet (2) upper end outerplanar is close to crag anchor hole surrounding.Rotating nut (1), can realize nut (1) and be threaded with threaded anchor rod (3), and nut (1) contacts fastening with pallet (2) taper seat wedge shape, and three closely links together.
Adopt a kind of Novel threaded anchor pole afterbody fastener of the present utility model, can realize:
1. nut (1) inner surface is helicitic texture, and realization is threaded with threaded anchor rod (3); Nut (1) profile presents two sections, and hypomere is hexagonal prism shape, realizes convenient rotation fastening; It is conical that epimere is, and the taper shape of crossing internal surface of hole with pallet (2) center carries out wedge shape taper seat and contact fasteningly, and face-face of realizing between the two contacts.
2. internal surface of hole is crossed for conical in pallet (2) center, realizes wedge shape taper seat to contact fastening with the taper shape of nut (1) epimere external surface; Pallet (2) profile is back taper, and the less one end of area is downward; Upwards, outerplanar is close to crag anchor hole surrounding to the larger one end of area, realizes more large area contact crag.
The technique effect that the present utility model is brought is:
1. wedge shape taper seat close contact between nut (1) and pallet (2), because be that face-face contacts and avoided stress to concentrate, can significantly improve both supporting capacitys.
2. between nut (1) and threaded anchor rod (3), adopt and be threaded, nut (1) and pallet (2) center cross that between internal surface of hole, to take wedge shape taper seat to contact fastening, pallet (2) upper end outerplanar is close to crag anchor hole surrounding, rotating nut (1) can make three closely link together, thereby significantly improves the anchored force of threaded anchor rod afterbody entirety.
Brief description of the drawings
Accompanying drawing is apparatus structure schematic diagram of the present utility model.
The symbol relating in figure represents respectively: 1. nut; 2. pallet; 3. threaded anchor rod.
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further.
Detailed description of the invention
Device of the present utility model carries out anchor pole afterbody when taking threaded anchor rod supporting and is fastened securely.Concrete implementation process is: nut (1) is worn threaded anchor rod (3) and pallet (2) center via hole.Nut (1) inner surface is helicitic texture, between nut (1) and threaded anchor rod (3), adopts and is threaded.Nut (1) profile presents two sections, and hypomere is hexagonal prism shape, and convenient rotation is fastening; It is conical that epimere is, and the taper shape of crossing internal surface of hole with pallet (2) center is realized wedge shape taper seat and contacted fastening.Internal surface of hole is crossed for conical in pallet (2) center, realizes wedge shape taper seat to contact fastening with the taper shape of nut (1) epimere external surface; Pallet (2) profile is back taper, and the less one end of area is downward; Upwards, outerplanar is close to crag anchor hole surrounding to the larger one end of area.Rotating nut (1), can realize nut (1) and be threaded with threaded anchor rod (3), and nut (1) contacts fastening with pallet (2) taper seat wedge shape, and three closely links together.
