Abstract
The utility model relates to a flexible pin locking formula stock comprises the body of rod, nut, tray gasket, tray, the sleeve pipe of taking the cotter hole, sleeve pipe gasket, eight parts of pin and spring washer. Body of rod outside sets up a plurality of conical bodies, and body of rod afterbody is equipped with the anchor head, and the anchor head is the cylinder, the inside out grouting holes that is equipped with of anchor head, and body of rod center is equipped with and leads to long slip casting pipe, out grouting holes and slip casting pipe UNICOM. The outside shape of sleeve pipe is the cylinder to be equipped with the cotter hole, the body of rod and sleeve pipe upper portion separate with spring washer.
Description
Technical field
The utility model relates to a kind of flexible pin locking type anchor, is particularly useful for geotechnical anchor engineering.
Background technology
Anchor pole is widely used in underground construction, but along with the increasing of engineering-environment complexity and difficulty of construction, accordingly to the requirement also corresponding raising of Soil Anchor Design, the increase of especially anchor rod anchored ability is most important.General anchor pole is all by the pressure that increases between loop bar and rock mass of expanding to reach anchoring ability, but this anchoring ability is often not enough to the needs meeting anchored force, and the anchored force that may exist locks not enough problem.
Summary of the invention
The present invention is a kind of flexible pin locking type anchor, is made up of the sleeve pipe of the body of rod, nut, shim tray, pallet, band pin hole, sleeve pipe pad, pin and elastomeric pad.Body of rod outside is provided with multiple bullet, and bullet matches with pin, and body of rod afterbody is provided with anchorage head, and anchorage head is cylinder, and body of rod center is provided with elongated Grouting Pipe, and anchorage head inside is provided with slurry outlet, slurry outlet and Grouting Pipe UNICOM.Described jacket exterior shape is cylinder, and is provided with pin hole.
During use, first carry out the assembling of anchor pole, after assembling, the present invention's entirety is sent in rock body drilled, by fastening nut, due to the effect of elastomeric pad, the body of rod can outwards have certain displacement relative to sleeve pipe, in moving process, bullet can extrude pin, make pin stretch out jacket exterior and arrive rock mass, then by Grouting Pipe slip casting, thus reach anchoring effect.
As improvement, between the body of rod and sleeve pipe, add elastomeric pad, thus sleeve pipe need not arrange gap also can not make casing failure.
As improvement, add bullet at the cylindrical body of rod.
As improvement, cooperatively interacting and easy slide of bullet and pin, makes pin can free-extension length.
The invention has the beneficial effects as follows: when anchor pole works, by design bullet and the cooperatively interacting of pin, reach the object of pin free-extension, just solve the anchored force problem of anchor pole, described device composition is simple simultaneously, easy for installation, efficiency of construction improves greatly, avoids the deficiency of traditional expansion type roof bolt.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present invention;
Fig. 2 is the anchor pole schematic diagram after stretching;
Fig. 3 is A-A sectional drawing;
Fig. 4 is B-B sectional drawing;
Wherein, sleeve pipe (8), Grouting Pipe (9), anchorage head (12), the slurry outlet (13) of the body of rod (1), nut (2), pallet (3), shim tray (4), sleeve pipe pad (5), pin (6), band pin hole.
Embodiment
With reference to the accompanying drawings 1, the utility model is that a kind of flexible pin locking type anchor is by the body of rod (1), nut (2), pallet (3), shim tray (4), sleeve pipe pad (5), pin (6), sleeve pipe (8) with pin hole and elastomeric pad (11) composition, the described body of rod (1) outside is made up of multiple bullet (7), the body of rod (1) afterbody is provided with anchorage head (12), anchorage head (12) is cylinder, the body of rod (1) center is provided with elongated Grouting Pipe (9), anchorage head (12) inside is provided with slurry outlet (13), slurry outlet (13) and Grouting Pipe (9) UNICOM, described sleeve pipe (8) outer shape is cylinder, pin (6) matches with the bullet (7) of the body of rod, after anchor pole assembles, be put in the boring of accomplishing fluently, now there is not pressure between pin (6) and bullet (7), pin (6) is positioned at pin hole, after fastening nut (2), pressure is produced between the bullet (7) of pin (6) and the body of rod, thus make pin (6) exposed to jacket exterior until extend in rock mass, then by Grouting Pipe (9) slip casting.
Claims (4)
1. a flexible pin locking type anchor, by the body of rod (1), nut (2), pallet (3), shim tray (4), sleeve pipe pad (5), pin (6), sleeve pipe (8) with pin hole and elastomeric pad (11) composition, the described body of rod (1) outside is made up of multiple bullet (7), it is characterized in that: the body of rod (1) afterbody is provided with anchorage head (12), anchorage head (12) is cylinder, the body of rod (1) center is provided with elongated Grouting Pipe (9), anchorage head (12) inside is provided with slurry outlet (13), slurry outlet (13) and Grouting Pipe (9) UNICOM, described sleeve pipe (8) outer shape is cylinder, pin matches with the bullet (7) of the body of rod.
2. to stretch pin locking type anchor according to the one described in claim 1, it is characterized in that: pin is hidden in sleeve pipe just when the bottom of bullet.
3. to stretch pin locking type anchor according to the one described in claim 1, it is characterized in that: the quantity of described slurry outlet is 4, and angle is each other 90 degree.
4. to stretch pin locking type anchor according to the one described in claim 1, it is characterized in that: pin can along with the displacement between the body of rod and sleeve pipe in pin hole free-extension.
