1., in the engineering plane of design raft plate, the distribution density of anti-float anchor rod is comparatively large, and after doing embayment anchor form, the space in the scope of operation uses and receives serious restriction, cannot provide basic plane operation environment for other plant equipment and personnel's material;
2. because anchor pole indulges the upper heights of roofs of muscle in 1/2 ~ 2/3 altitude range of raft plate, do not reach the absolute altitude of raft plate epithelium distribution bar, therefore in construction, needing, supporting steel bar is additionally set and temporary support is carried out to raft plate epithelium distribution bar;
3. longitudinal anchor pole muscle of anchor pole needs to carry out twice bending machining, and the forming face bent for twice requires to remain in same plane, and the technical standard of processing is higher, but the processing conditions at scene is not easy to the execution of this type of technical requirements.
In sum, need a kind of reliable drawknot that can either ensure between self and raft plate now, the novel raft plate anti-floating anchor rod structure that simultaneously can solve the problem again.
Summary of the invention
The present invention is the above-mentioned deficiency in order to solve existing for prior art, a kind of simple structure is proposed, design ingenious, under the prerequisite ensureing the technical requirements of building construction of bottom plates, the plane operation space in foundation construction stage can be increased, and do not need additionally to arrange supporting steel bar carries out temporary support raft plate anti-floating anchor rod structure to basic epithelium distribution bar.
Technical solution of the present invention is: a kind of raft plate anti-floating anchor rod structure, comprise anchor pole 1, it is characterized in that: in described anchor pole 1, be provided with two anchor pole muscle 2 elongated with anchor pole 1 symmetrically, anchor pole muscle 2 is exposed to anchor pole 1 top, adopt two-sided overlap welding technique to help to be welded with short dowel 3 in the upper end of anchor pole muscle 2, short dowel 3 is axially parallel with anchor pole muscle 2.
The part that described two symmetrically arranged anchor pole muscle 2 expose anchor pole 1 is that herringbone is arranged.
The weld length of described anchor pole muscle 2 is at least 7 times of self bar diameter of anchor pole muscle 2, and the weld length of described short dowel 3 is at least 7 times of short self bar diameter of dowel 3.
The diameter of described short dowel 3 is more than or equal to the diameter of anchor pole muscle 2, and the strength grade of short dowel 3 is identical with the intensity of anchor pole muscle 2.
Compared with the existing technology, advantage is as follows in the present invention:
The raft plate anti-float anchor rod of this form of structure, its structure is simple, and design ingenious, form is reasonable.The drawknot effect of traditional anti-floating anchor rod structure in order to reach and between raft plate, the elongated reinforcing bar longitudinally arranged need make horizontal curved anchor at raft intralamellar part, and cause foundation work space of planes not enough, slightly large plant equipment just cannot enter foundation construction region job; Secondly, in the raft plate reinforcing bar binding stage, traditional anchor structure design needs additionally to arrange supporting steel bar and supports raft plate epithelium distribution bar; Its three, the reinforcing bar section of anchoring into of anti-float anchor rod need do twice bending process in advance, and twice bending forming face requires to remain in same plane, and difficulty of processing is larger.For above-mentioned engineering disadvantage, the present invention discloses a kind of novel raft plate anti-floating anchor rod structure, this structure has abandoned the existing elongated anchor pole muscle engineering practice that horizontal curvature anchors in raft plate, the basis of original longitudinal anchor pole muscle straight anchor section increases by one section of short dowel, carry out the two-sided overlap joint of axis with anchor pole muscle to help to weld, utilize the bar splicing enlarged footing formed that misplaces to carry out anchoring compensation.This tectonic sieving has following advantage compared to traditional structure: one, and maximum optimization has been carried out in the plane operation space in foundation construction stage by this anti-floating anchor rod structure, solves the present situation of plane usefull space deficiency to a certain extent; Its two, the upper end of short dowel can be used to carry out temporary support to the epithelium distribution bar of raft plate, without the need to separately establishing special supporting steel bar, Simplified flowsheet, cost-saving; Its three, due to short dowel need be shorter by length, the tailing produced in reinforced bar engineering manufacturing process can be adopted to process, realize waste resource recycling, cost efficiency; Its four, longitudinal anchor pole muscle form of this anchor structure is simple, substantially can not consider the bending reprocessing of reinforcing bar, improve operating efficiency.In brief, the anti-floating anchor rod structure in the present invention has possessed multiple advantage, is particularly suitable for adding applying in anti-float anchor rod foundation structure field at raft plate, and its market prospects are very wide.
