Abstract
The utility model relates to an assembled grouting anchor rod which comprises an anchor head, a grout stopping plug, a shim plate and a screw nut. The utility model is characterized in that the anchor head is fixedly connected with a threaded steel pipe which is connected with a connecting sleeve, and the connecting sleeve is connected with a hollow threaded pipe on which the grout stopping plug is arranged; the end of the hollow threaded pipe is provided with the shim plate and the screw nut, a through hole is arranged on the connecting sleeve and the through hole is connected with an inner hole of the hollow threaded pipe. The utility model has the advantages that cement grout is overflowed and poured from the middle part, and the cement grout is perfuse towards both sides, so the construction time can be accelerated, the consumption of the hollow threaded pipes of the slurry injecting anchor rods is saved, thereby, the production cost can be reduced.
Description
Technical field
The utility model relates to a kind of grouted anchor bar, particularly a kind of combined type grouted anchor bar.
Background technology
On building site, heavy construction basis, often adopt grouted anchor bar to come massif slope or tunnel wall are reinforced at present, existing grouted anchor bar generally is to utilize the screwed pipe of a hollow to add anchor head, stop grouting plug, backing plate and nut constitute, after boring on the bodies that are fixed such as massif slope or tunnel wall, grouted anchor bar is inserted in the hole, screwed pipe by hollow grout injection inward then, but because cement paste is to enter into the hole that is poured from anchor head, the cement paste of high-pressure slip-casting back overflows from anchor head, it is full to be in the milk to whole hole, need long time, influenced the efficient of construction, and the screwed pipe material cost and the processing cost of hollow are higher, and the cost of grouted anchor bar is risen greatly.
Summary of the invention
The purpose of this utility model is to solve existing the problems referred to above of grouted anchor bar in the prior art, and the combined type that a kind of cost is low, efficiency of construction is high grouted anchor bar is provided.The box-like grouted anchor bar of the utility model design team, comprise anchor head, stop grouting plug, backing plate, nut, it is characterized in that: the fixedly connected threaded steel pipe of anchor head, threaded steel pipe is connected with adapter sleeve, adapter sleeve connects the screwed pipe of hollow again, on the screwed pipe of hollow stop grouting plug is arranged, and the end of the screwed pipe of hollow has backing plate and nut, through hole is arranged on the adapter sleeve, and through hole connects the cannulated threaded pipe orifice.The utility model has the advantages that cement paste by the excessive notes in middle part, pours into toward both sides, can accelerate the engineering time, and save grouted anchor bar cannulated threaded pipe use amount, thereby can reduce production costs.
Description of drawings
Below in conjunction with drawings and Examples the utility model is elaborated,
Accompanying drawing is a structural representation of the present utility model,
The specific embodiment
Comprise anchor head 1, stop grouting plug 2, backing plate 3, nut 4 among the figure, it is characterized in that: anchor head 1 fixedly connected threaded steel pipe 5, threaded steel pipe 5 is connected with adapter sleeve 6, adapter sleeve 6 connects the screwed pipe 7 of hollow again, on the screwed pipe 7 of hollow, stop grouting plug 2 is arranged, the end of the screwed pipe 7 of hollow has backing plate 3 and nut 4, and through hole 8 is arranged on the adapter sleeve 6, and through hole 8 connects the endoporus 9 of the screwed pipe 7 of hollow.During use the combined type grouted anchor bar is inserted in the boring on the body that is fixed, insert a stack 10 simultaneously at the bottom of the hole, then slurry casting machine is twisted and be connected on the screwed pipe 7 of the hollow that exposes, with compression pump cement is injected in the endoporus 9, cement paste is entered by the endoporus 9 of the screwed pipe 7 of hollow, through hole 8 from the adapter sleeve 6 at combined type grouted anchor bar middle part gets out again, then from the past both sides slip casting simultaneously of the middle part of through hole 8, the air at the boring end is discharged by stack 10, has shortened the time of construction greatly.
