Description

A kind of anti-lateral deflection anti-float anchor rod of retardation setting type and construction method thereof
Technical field
The present invention relates to field of civil engineering, particularly relate to a kind of anti-lateral deflection anti-float anchor rod of retardation setting type and construction method thereof。
Background technology
Anti-float anchor rod is conventional a kind of structural elements to underground structure, underground structure offer anti-floating ability。Its body of rod is made by reinforcing bar, steel strand wires, steel pipe etc., and major part is implanted in foundation soil, and upper end anchors into basis。When underground structure, structures suffer water buoyancy upwards, anti-float anchor rod will retrain building, structures, it is prevented that it floats。
In construction period owing to adopting precipitation means, basement is also not affected by the effect of upwards water buoyancy;Along with the progressively construction of upper building, downward pressure incrementally increases, and basis is inevitable produces downwards certain sedimentation。And the anti-float anchor rod body of rod is elongated metallic member, it is possible to produce bigger anti-pulling capacity but pressure cannot be born, therefore along with setting of ground, anchor rod body certainty compressive buckling。
When construction completes, precipitation terminates, basement start to bear upwards water buoyancy time, be only possible to after the anti-float anchor rod of lateral deflection stretches to basement provide constraint。So not only anti-float anchor rod is poor to basement anti-floating binding effect, and the anti-float anchor rod body of rod is under pressure is drawn repeatedly, and intensity also can decline to some extent。
Therefore, it is necessary to prior art is improved。
Summary of the invention
It is an object of the invention to provide a kind of anti-lateral deflection anti-float anchor rod of retardation setting type and construction method thereof, it is prevented that construction period anti-float anchor rod compressive buckling, and then weaken anti-floating binding effect and lever strength。
For achieving the above object, the present invention is by the following technical solutions:

Further, described metal tube is metal bellows。
Further, described cock body is that the middle part of rubber stopper is provided with mean for the through hole of body of rod traverse in round table-like rubber stopper。
Further, the upper end of described metal tube is provided with aspirating hole。
The construction method of the anti-lateral deflection anti-float anchor rod of more than one described retardation setting types, including:
S1, by metal tube be inverted, in metal tube inject retarding mortar;
S2, cock body is enclosed within the body of rod, and body of rod top is inserted in metal tube;
Metal tube and the body of rod are together just put after being blocked by metal tube lower ending opening by S3, use cock body;
S4, treat that retarding mortar flow to metal tube bottom, in formation gap, metal tube top;
S5, implant in foundation soil internal drilling and by the bottom of the body of rod, then be cased with metal tube place on body of rod top and water and smash construction basis。
Further, described S4 also includes: extract the air in gap out。
The present invention utilizes the characteristic of retarding mortar, by above-mentioned structure, starts sedimentation along with upper load strengthens basis in work progress, and during retarding mortar ot-yet-hardened, the body of rod can freely-movable in metal tube, it is ensured that the body of rod is not by lateral deflection;To be onstructed complete, after foundation settlement is stable, retarding mortar solidifies, and the body of rod plays anti-floating effect。
Compared with prior art, basement is had better anti-floating binding effect by retardation setting type provided by the present invention anti-lateral deflection anti-float anchor rod, also ensure that lever strength is not because pressure repeatedly is drawn and reduced。

Detailed description of the invention
Below in conjunction with accompanying drawing and specific embodiment, technical scheme is described in detail。
As depicted in figs. 1 and 2, the problem weakening anti-floating binding effect and lever strength for solving construction period anti-float anchor rod compressive buckling, the invention provides a kind of anti-lateral deflection anti-float anchor rod of retardation setting type。Specifically, it includes the body of rod 1, metal tube 2, retarding mortar 3, cock body 4;Described metal tube 2 is anchored in basis 5, the inner hollow of metal tube 2 and be perfused with retarding mortar 3, the upper end closed of metal tube 2 and lower ending opening;The bottom of the described body of rod 1 is implanted in foundation soil 6, and the top of the body of rod 1 is through cock body 4 and stretches in metal tube 2;Described cock body 4 is arranged at metal tube 2 lower ending opening place, is blocked by metal tube 2 lower ending opening and metal tube 2 and the body of rod 1 is relatively fixed;An intersegmental gap 10 is left between upper end and the upper end inwall of metal tube 2 of the body of rod 1。
Retarding mortar 3 is by extraordinary mortar through suitable proportioning of cement, compound retarder and sand, can not solidify within a longer time period, and higher-strength can be reached after solidifying, how to be applied in prestressed concrete engineering as grouting material at present。
By above-mentioned structure, along with upper load strengthens in work progress, basis 5 is when starting to settle, retarding mortar 3 ot-yet-hardened, and the body of rod 1 can freely-movable in metal tube 2, it is ensured that the body of rod 1 is not by lateral deflection。To be onstructed complete, after basic 5 settlement stabilities, retarding mortar 3 solidifies, and the body of rod 1 plays anti-floating effect。
Further, as it is shown on figure 3, in the embodiment of the present invention, described metal tube 2 preferably employs metal bellows, ripple can strengthen and is engaged ability between metal tube 2 and retarding mortar 3 and basis 5。
Further, as shown in Figure 4, described cock body 4 is in round table-like rubber stopper, and the middle part of rubber stopper is provided with mean for the through hole 41 of the body of rod 1 traverse。The Main Function of cock body 4 is to prevent retarding mortar 3 from leaking down and the motion of the body of rod 1 is play the guiding role, the compressibility of the above-mentioned shape cooperation rubber of cock body 4, when basis 5 sinks, cock body 4 is progressively clamp-oned in metal tube 2, to reduce the obstruction that the body of rod 1 freely-movable is produced。
Further, as it is shown on figure 3, the upper end of described metal tube 2 is provided with aspirating hole 20。After the anti-lateral deflection anti-float anchor rod of retardation setting type provided in the embodiment of the present invention is completed, it is possible to extract the air in gap 10 by aspirating hole 20, it is compressed to and to a certain degree produces to hinder to the freely-movable of the body of rod 1 afterwards reducing this partial air。
The embodiment of the present invention additionally provides the construction method of the anti-lateral deflection anti-float anchor rod of more than one described retardation setting types, and specifically, described construction method includes:
S1, metal tube 2 is inverted, metal tube 2 injects retarding mortar 3;
S2, cock body 4 is enclosed within the body of rod 1, and the body of rod 1 top is inserted in metal tube 2;
Metal tube 2 and the body of rod 1 are together just put after being blocked by metal tube 2 lower ending opening by S3, use cock body 4;
S4, treat that retarding mortar 3 flow to metal tube 2 bottom, behind formation gap, metal tube 2 top 10;The air in gap 10 is extracted out by aspirating hole 20;
S5, according to general anti-float anchor rod work progress, implant in foundation soil 6 internal drilling and by the bottom of the body of rod 1, then be cased with on the body of rod 1 top metal tube 2 place water smash construction basis 5。
Embodiment described above only have expressed the several embodiments of the present invention, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention。It should be pointed out that, for the person of ordinary skill of the art, without departing from the inventive concept of the premise, it is also possible to making some deformation and improvement, these broadly fall into protection scope of the present invention。Therefore, the protection domain of patent of the present invention should be as the criterion with claims。
