Description
Technical field
The utility model relates to technical field of fastening, is that one is mainly useful in building specifically, the fixing crab-bolt in the fields such as decoration.
Background technique
Known, to install at equipment, highway bridge guardrail is installed, building strengthening, constructure screen wall, marble is cladding to be waited in construction, and fixing crab-bolt is usually for taking root on metope, ground.
In prior art, fixing crab-bolt mainly contains two kinds, one is expansion anchor, it mainly comprises nut, double-screw bolt, expansion tube and conical nose, when use, on concrete sill body, get out the hole with crab-bolt diameter corresponding size, again bolt, expansion tube packs in boring, then screw nut, conical nose and expansion tube move toward one another, in the time that conical nose enters expansion tube, expansion tube is extruded distortion and is full of and in hole, produces shearing force, thereby make bolt, expansion tube, between assembling set and concrete sill body, be fixed into and be integrated, the defect of this expansion anchor is that anchor force is less, in continuous vibration or alternating stress situation, easily get loose etc.The second is chemical anchor bolts, it comprises out threaded anchor pole, nut, the metal parts such as pad and with it supporting chemical glue part, when use, on concrete sill body, get out the hole than crab-bolt slightly larger in diameter with electric drill or other cutting instruments, then in hole, push chemical glue, crab-bolt is screwed in hole, after chemical glue solidifies, be fixed in the boring of concrete base material cementing screw rod.The anchor force of chemical anchor bolts is large, but its defect is before solidifying completely, must keep crab-bolt state of rest after chemical glue gel, in the time that chemical anchor bolts are used for the installation of end face workpiece, the top support body of for example subway tunnel is fixed, the lifting part of other building end faces is taken root etc., due to crab-bolt certainly focus on chemical glue gel before cannot in boring, keep static, in practice of construction, will go fixing crab-bolt with special bearing support or bar, cause like this installation efficiency of chemical anchor bolts very lowly loaded down with trivial details, and increase the cost of having constructed.
So the installation efficiency when how solving chemical anchor bolts and installing for end face workpiece is that those skilled in the art have practical problem urgently to be resolved hurrily.
Summary of the invention
For the defect of above-mentioned prior art and the technical problem of existence, the technical problem that the utility model solves is to provide a kind of pre-expansion chemical anchor bolts that end face anchoring is taken root that are applicable to.
The technological scheme of the utility model technical solution problem is: the chemical anchor bolts that expand in advance, comprise anchor pole, nut; It is characterized in that aforementioned anchor pole comprises Full Thread FT chemistry anchor pole portion, be set with expansion anchor rod portion and the conical nose of expansion tube, and aforementioned Full Thread FT chemistry anchor pole portion, expansion anchor rod portion and conical nose are solidly fixed successively.
Preferred technological scheme: the two ends of aforementioned conical nose comprise respectively the extruding conical surface and the guiding conical surface, and axially have at least one guiding gutter along it.
Preferred technological scheme: aforementioned guiding gutter is uniform three.
Preferred technological scheme: also comprise that locked spacer and pad are for coordinating with nut.
Preferred technological scheme: described anchor pole can adopt carbon steel, stainless steel or alloyed steel metallic material.
Technique effect of the present utility model is: the technical program is combined into one chemical anchor bolts and expansion anchor, in the time fixedly taking root for end face workpiece, before chemical glue gel, expansion anchor rod portion provides anchor force and has kept that crab-bolt is static is not subject to disturbance for fixture, after chemical glue gel, chemistry anchor pole and expansion anchor rod provide high-intensity anchor force to fixture simultaneously, compared to existing technology, the technical program is well suited for end face construction, not needing increases extra supporting bridge, and not only efficiency of construction is high but also cost-saving; Secondly, the technical program is not only applicable to end face and executes public affairs, is also applicable to metope, ground construction, and under same intensity, can provide than single chemical anchor bolts or the larger anchor force of expansion anchor, the prior art of comparing has outstanding technique effect.

Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is elaborated, further illustrate advantage of the present utility model and the outstanding contributions with respect to prior art, understandable, following embodiment is taking M14 crab-bolt as example, be only the detailed description to the better embodiment of the utility model, should not be construed as any restriction to technical solutions of the utility model.
The utility model mainly comprises anchor pole 1, nut 2, locked spacer 21, and packing ring 22 etc., above-mentioned parts can select the metallic material such as carbon steel, stainless steel or alloyed steel to make conventionally, and workpiece surface is hot galvanizing etc. on request.
As shown in Figure 1, anchor pole 1 is mainly one-body molded by three parts, maximum diameter is 14mm, wherein upper end is Full Thread FT chemistry anchor pole portion 11, long 115mm, the main generation anchor force that matches with chemical glue of this part, helical thread portion is conducive to increase the area of contact of chemical glue and the body of rod, and after gel, anchor force is stronger.With Full Thread FT chemistry anchor pole portion 11 seamless links be expansion anchor rod portion 12, it is that one section of optical axis outside wears expansion tube 14.As shown in Figure 2,3,13 one-tenth of the conical noses of end are olive-shaped, and the part coordinating with expansion tube 14 is the extruding conical surface 131, and the other end is the guiding conical surface 132, along axial uniform three guiding gutters 133 of conical nose 13.The chemical glue being used in conjunction with this crab-bolt can select conventionally gathers around anchoring adhesive, chemical pencil (glass tube, reacting resin, curing agent and quartz particles) or with plastics packed medicament pipe.
When use, open mounting hole in the concrete substrate body of end face, ground or metope with electric drill or other drilling tools, this mounting hole is offered into similar step hole, the aperture of its middle front part is used for and expansible anchor spigot 12 and conical nose 13 Spielpassung, it is substantially consistent with crab-bolt diameter that it offers diameter, and it is large to hold chemical glue compared with crab-bolt diameter that rear portion macropore is offered diameter.In practice, for example the present embodiment crab-bolt diameter 14mm, hole diameter is offered into 14mm substantially, macropore 16mm.After holding hole successfully, push chemical glue, then insert crab-bolt, now, the cone structure of the guiding conical surface 13 can prevent that crab-bolt is parked on large aperture joint, after the guiding conical surface 13 enters aperture, chemical glue is outwards extruded along guiding gutter 133, thereby prevent piston effect, so that crab-bolt is inserted mounting hole smoothly; Screw nut 2, produce anchor force thereby the extruding conical surface 131 extrusion expansion pipes 14 are out of shape swelling; Before chemical glue gel, crab-bolt transfixion, until produce bonding anchor force after chemical glue gel.
The utility model has solved existing crab-bolt and has been not suitable for the defect that end face is installed, and installation efficiency is high, saves construction cost, and the prior art of comparing has shown outstanding technological progress.
Below the preferred embodiment of the utility model having been created illustrates, but the utility model is created and is not limited to described embodiment, those of ordinary skill in the art also can make all modification being equal to or replacement under the prerequisite without prejudice to the utility model creative spirit, and the modification that these are equal to or replacement are all included in the application's claim limited range.
