Description
Technical field
The invention belongs to technical field of buildings, and in particular to a kind of novel anti-float anchor rod and its construction method.
Background technique
In building construction process, structure located underground usually requires to take measure of anti float, mainly uses at this stage
Measure of anti float is that anti-float anchor rod is set on ground.From the point of view of existing Construction Technology of Anti-floating Anchor, more conventional way
Be using regular reinforcement as shank member, in order to reach anchor pole resistance to plucking design value, often in a bolthole placement two or
Two or more regular reinforcements；Due to being influenced by reinforcing bar radical, reinforcing bar placement is more, and the frictional force generated inside grouting material is got over
Low, to reduce the withdrawal resistance of anchor pole, causing cannot be effectively ensured in quality in this way, while on amount of reinforcement
It is a kind of waste.Coefficient of friction is lower and not complete between the reinforcing bar body of rod and grouting material, foundation soil of the anchor pole of this construction method construction
Holotype is at enclosure space, and moisture easily penetrates the cement slurry corrosion reinforcing bar body of rod between soil, to reduce the anti-pulls coefficient of anchor pole.
Therefore, it is badly in need of a kind of anti-float anchor rod system, to solve the above technical problems.
Summary of the invention
The object of the present invention is to provide a kind of novel anti-float anchor rod and its construction methods, are replaced with fining twisted steel anchor pole former
Carrying out conventional regular reinforcement anchor pole, the breakout capacity enhancing of anchor pole can effectively solve the drawback in traditional construction quality, while
It is that a kind of reduction wastes, economizes on resources, reduces cost, builds a kind of green construction theory.
The technical solution that the present invention solves technical problem is as follows:
A kind of novel anti-float anchor rod of the present invention, it includes the fining twisted steel body of rod；The top of the fining twisted steel body of rod
It is arranged to be provided with water-swellable sealing ring in the bent anchor of bending, upper part, its underpart is provided with several hangnail type positioning
Bracket, bottom end are provided with disrance sleeve.
Further, the intensity setting value of the fining twisted steel body of rod is 1080N/mm2.
Further, the angle of the bent anchor in bending is 90 degree.
Further, the hangnail type locating support is made using regular screw threads steel, under the fining twisted steel body of rod
Portion is placed equidistant with.
Further, the material of the disrance sleeve is inertia rubber.
The construction method of a kind of novel anti-float anchor rod based on the above-mentioned technical proposal, includes the following steps:
1) bolthole, is drilled through using jumbolter at design position according to drawing requirement, clears up whole hole；
2), disrance sleeve is mounted on to the lower port of the fining twisted steel body of rod；
3), the fining twisted steel body of rod with hangnail type locating support is seated in bolthole and is fixed, guarantees finish rolling
The bent anchor of screw-thread steel body of rod upper port protrudes into bottom plate and anchorage length meets design requirement；
4) high-pressure slip-casting, is carried out in bolthole, it is ensured that grouting material is closely knit；
5), in bottom cushion and construction of waterproof layer, water-swellable sealing ring is sleeved on the fining twisted steel body of rod；
6) construction of ground house bottom plate, is finally carried out by drawing.
Further, the grouting material is high density pea gravel concreten.
Compared with prior art, the present invention need to only place a fining twisted steel, and fining twisted steel strength failure criterion is
1080N/mm2 is 3 times of regular reinforcement strength failure criterion, by reducing shank member quantity in hole and adding hangnail type positioning branch
Frame increases the tensile strength design value of single anchor rod part, increases its anti-float anchor rod pulling test strength, reinforces rubbing inside grouting material
Power, withdrawal resistance enhancing are wiped, while construction is more simplified.The characteristics of present invention has design rationally, construction is simple, reduces waste.
