Abstract
The utility model relates to the technical field of anchor bolts, in particular to a combined anchor bolt. The combined anchor bolt comprises a hollow grouting anchor bolt body, a nut, a base plate, a grout stop plug, a solid anchor bolt body and an anchor head, the nut, the base plate and the grout stop plug are arranged on the hollow grouting anchor bolt body, an internal thread at the end of the hollow grouting anchor bolt body is connected with an external thread of the solid anchor bolt body in a matched mode, and the hollow grouting anchor bolt body is provided with a grouting hole and an exhaust hole. Due to the fact that thread connection is adopted in the combined anchor bolt, the combined anchor bolt is rapid to install and stable in structure, and intensity detection is convenient; the phenomenon that grout blocking of an anchor hole is caused by use of a connection sleeve is avoided, and grout is made to flow more smoothly.
Description
Technical field
The utility model relates to a kind of anchor pole, particularly a kind of combined anchor.
Background technology
combined anchor is because of rational in infrastructure, easy construction, technique, can guarantee that slip casting is full, consolidation, more and more be subject to the welcome of all kinds of operating mode industry concrete support operation, the combined anchor adopting is at present mainly by the hollow bolt body of rod, solid anchor rod body, anchor head and an adapter sleeve form, if the patent No. is disclosed a kind of combined anchor in the Chinese invention patent of ZL 01143077.X, mainly by nut, backing plate, stop grouting plug, the hollow bolt body of rod, slip casting passage, pulp passage, exhaust passage, linkage section, solid anchor rod body, anchor head and anchor hole form, because the hollow bolt body of rod is connected and constitutes anchor rod body integral body with solid anchor rod body through special linkage section, pulp passage is just on linkage section.In this invention, described linkage section is that inner surface is driven threaded sleeve pipe, when the external diameter of the hollow bolt body of rod and solid anchor rod body is different, linkage section also there will be reducer, the subject matter of such design is: linkage section internal thread is divided into two sections and connects respectively two sections of anchor bar bodies, can make the strength decreased of linkage section; The external diameter of linkage section is all larger than the external diameter of two bodies of rod, very easily causes the stifled slurry of anchor hole, affects the mobile patency of slurries.
Utility model content
The purpose of this utility model is: the problem existing for prior art, provides a kind of two sections of combined anchors that anchor rod body is directly threaded.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of combined anchor, comprise the hollow grouting anchor body of rod, nut, backing plate, stop grouting plug, solid anchor rod body and anchor head, described nut, backing plate and stop grouting plug are arranged on the hollow grouting anchor body of rod, the supporting connection of external screw thread of the end internal thread of the described hollow grouting anchor body of rod and solid anchor rod body, on the described hollow grouting anchor body of rod, have injected hole and steam vent.
As preferred version of the present utility model, injected hole on the described hollow grouting anchor body of rod and steam vent are arranged near hollow grouting anchor body of rod internal thread side, injected hole and steam vent are set directly on the hollow grouting anchor body of rod, have avoided the easily impact of stifled slurry of using adapter sleeve to bring.
As preferred version of the present utility model, the internal thread length of the described hollow grouting anchor body of rod is not less than 20mm, guarantees that this combined anchor integral body has enough connecting lengths and intensity.
Combined anchor of the present utility model, change the connecting jacket structure of prior art into direct screw connection structure, at the end of hollow grouting anchor body of rod machining internal thread, with it supportingly at the end of solid anchor rod body threading, be equivalent to the as a whole body of rod of the whole combined anchor body of rod, quick for installation, Stability Analysis of Structures, easy to detect; Do not use adapter sleeve, can than the external diameter of two bodies of rod, all not cause greatly the stifled slurry of anchor hole phenomenon because of the external diameter of adapter sleeve, slurries are flowed more unobstructed.
In sum, owing to having adopted technique scheme, the beneficial effects of the utility model are:
1, the combined anchor being threaded connection, quick for installation, Stability Analysis of Structures, detected intensity is also convenient;
2, avoided, because using adapter sleeve to cause the phenomenon of the stifled slurry of anchor hole, slurries being flowed more unobstructed.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model combined anchor.
Mark in figure: the 1-hollow grouting anchor body of rod, 2-nut, 3-backing plate, 4-stop grouting plug, the solid anchor rod body of 5-, 6-anchor head, 11-injected hole, 12-steam vent.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
embodiment 1
As shown in Figure 1, combined anchor, comprise the hollow grouting anchor body of rod 1, nut 2, backing plate 3, stop grouting plug 4, solid anchor rod body 5 and anchor head 6, described nut 2, backing plate 3 and stop grouting plug 4 are arranged on the hollow grouting anchor body of rod 1, the supporting connection of external screw thread of one end internal thread of the described hollow grouting anchor body of rod 1 and solid anchor rod body 5, on the described hollow grouting anchor body of rod, have injected hole 11 and steam vent 12.
As shown in Figure 1, injected hole 11 on the described hollow grouting anchor body of rod 1 and steam vent 12 are arranged near the hollow grouting anchor body of rod 1 internal thread side, injected hole 11 and steam vent 12 are set directly on the hollow grouting anchor body of rod 1, have avoided the easily impact of stifled slurry of using adapter sleeve to bring greatly because of adapter sleeve external diameter.
As shown in Figure 1, the internal thread length of the described hollow grouting anchor body of rod is not less than 20mm, guarantees that combined anchor integral body has enough connecting lengths and intensity.
In the utility model, described solid anchor rod body is selected screw-thread steel, at one end of solid anchor rod body threading; The described hollow grouting anchor body of rod is determined diameter according to the size of solid anchor pole, select suitable wall thickness, with solid anchor rod body link machining internal thread, after coupling together, such two sections of anchor rod bodies are equivalent to, for the holistic body of rod, guarantee the intensity of this combined anchor; Directly on the hollow grouting anchor body of rod, have injected hole and steam vent, little on the injecting cement paste structural integrity impact after slip casting, the stability of assurance injecting cement paste.
Combined anchor of the present utility model, changes the connecting jacket structure of prior art into direct screw connection structure, quick for installation, Stability Analysis of Structures, easy to detect; Do not use adapter sleeve, can than the external diameter of two bodies of rod, all not cause greatly the stifled slurry of anchor hole phenomenon because of the external diameter of adapter sleeve, slurries are flowed more unobstructed.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
