Abstract
The utility model relates to a hollow grouting anchor of high strength, comprising an anchor rod, a ball nut at the tail of the anchor rod and a ball type gasket. The utility model is characterized in that the anchor rod is a hollow tube and equipped with thread at outer surface, the inner top of the anchor rod is equipped with an anchor head of tubular shape. The front part of the anchor head is cracked to three pieces, and the outer surface of each piece is equipped with a plurality of barbs. The inner wall of the tube is equipped with thread corresponding to the thread of the anchor rod, and the inner wall is a cone from the back end to the top end. The back of the anchor rod is covered with a stop plug, and the stop plug is a rotary table with a through hole at the middle and equipped with a vent hole. The utility model has the advantages of not easily being pulled out and high strength of the anchor rod after grouting, simple construction, and reliable fixation of the anchor rod due to full grouting.
Description
Technical field
The utility model relates to a kind of anchoring piece, particularly a kind of hollow High strength bolt slip casting anchoring piece.
Background technology
In engineerings such as building site, tunnel, dam body, need at present to ground carry out radially, slope reinforcement, particularly in building foundation pit supporting, to the crucial especially construction task of the reinforcing of dell periphery, more existing reinforcement measures are to utilize the conventional method of soil nailing screw-thread steel slip casting, because the screw-thread steel that stretches in the ground does not have anchor head, so the anchor pole of screw-thread steel can not wrap up between two parties after piercing into grotto slip casting, reinforcing bar exposes corrosion and easily is pulled out, construction quality effect and duration that influence is reinforced.
Summary of the invention
The purpose of this utility model be solve in engineerings such as building site, tunnel, dam body, need in the prior art to ground carry out radially, slope reinforcement, particularly in building foundation pit supporting, to the crucial especially construction task of the reinforcing of dell periphery, more existing reinforcement measures are to utilize the conventional method of soil nailing screw-thread steel slip casting, because the screw-thread steel that stretches in the ground does not have anchor head, so the anchor pole of screw-thread steel can not wrap up between two parties after piercing into grotto slip casting, reinforcing bar exposes corrosion and easily is pulled out, mass effect that influence is reinforced and the problem of duration.The utility model design hollow High strength bolt slip casting anchoring piece, the spherical nut, the bowl-type pad that comprise anchor pole and anchor pole afterbody, it is characterized in that: anchor pole is a hollow tube, on the external surface of anchor pole screw thread is arranged, on the interior top of anchor pole, an anchor head is arranged, anchor head is a tubulose, its forward part is cleaved into three, several hangnails are arranged on the every external surface, have on the inner face tube wall and the corresponding screw thread of the screw thread of anchor pole, inwall is the conical surface by the rear end toward the top, is with a stop grouting plug on the rear portion of anchor pole, stop grouting plug has an air vent for the middle Rotary-table that through hole is arranged on the stop grouting plug.The utility model has the advantages that the anchor pole after the slip casting is difficult for the pull-out strength height, it is simple and direct to construct, and the full anchor pole of slip casting is fixing reliable.
Description of drawings
Below in conjunction with drawings and Examples the utility model is elaborated,
Accompanying drawing 1 is a structural representation of the present utility model,
Accompanying drawing 2 is an anchor head structural representation of the present utility model,
The specific embodiment
The spherical nut 2, the bowl-type pad 3 that comprise anchor pole 1 and anchor pole 1 afterbody among the figure, it is characterized in that: anchor pole 1 is hollow tube, screw thread 4 is arranged on the external surface of anchor pole 1, one anchor head 5 is arranged on the interior top of anchor pole 1, anchor head 5 is a tubulose, its forward part is cleaved into three 6, several hangnails 7 are arranged on every 6 the external surface, screw thread 4 corresponding screw threads 8 with anchor pole 1 are arranged on the inner face tube wall 9, inwall 9 is the conical surface by the rear end toward the top, be with a stop grouting plug 10 on the rear portion of anchor pole 1, stop grouting plug 10 has an air vent 11 for the middle Rotary-table that through hole is arranged on the stop grouting plug 10.To treat during use to hole on the ground stone of reinforcing place, put into anchor head 5, again anchor pole 1 is screwed on the anchor head 5, because the inwall 9 of anchor head 5 is the conical surface by the rear end toward the top is gradually thick, so three 6 of anchor head 5 front portions strut, and hangnail 7 hooks hole wall, in anchor pole 1, in the hole, be in the milk, air in the hole can be overflowed from the air vent on the stop grouting plug 10 11, guarantees that grouting is abundant, satisfies the needs of intensity.
