Abstract
The utility model relates to devices used for tightening or fixing elements or machine parts, in particular to a combination anchor bolt, which comprises a chemical rubber hose, wherein the chemical gum hose refers to a hose capable of placing chemical gum. The combination anchor bolt is characterized in that a thread rod matching with the chemical gum hose is an expandable thread rod. The combination anchor bolt has the advantages of simple structure, convenient and quick installation, which not only increases installation efficiency but meets the requirement of repeatedly detaching.
Description
Technical field
The utility model relates to the device class that fastening or fixed component or machine parts are used, and relates to a kind of assembly anchor bolt concretely.
Background technique
Traditional expansion anchor is when tightening hexagon nut, and the conical head of crab-bolt is advanced in the intumescent sheet by pull, makes it to expand and be pressed on the wall of a borehole, thereby produces frictional force and resist external force under the effect of external force.Be characterized in can being installed at once, save time by anchor, high working efficiency, but after being dismantled repeatedly by anchor, be easy to loosening and anchoring was lost efficacy.
Traditional chemical anchor bolts are with resin screw rod and concrete hole wall to be bonded together, and bear external force by bonding force.Be characterized in that anchoring is reliable, nut can be dismantled repeatedly, but it only just can be installed after anchor adhesive final set by anchor, thereby has wasted working efficiency, makes again inconvenience is installed.
Summary of the invention
The purpose of this utility model is according to above-mentioned the deficiencies in the prior art part, and a kind of assembly anchor bolt is provided, and the screw rod in this crab-bolt adopts inflatable screw rod, thereby has avoided the defective of prior art.
The utility model purpose realizes being finished by following technological scheme:
A kind of assembly anchor bolt comprises chemical sebific duct, it is characterized in that the screw rod that is used with chemical sebific duct is inflatable screw rod, and this chemistry sebific duct refers to the pipeline that can place chemical glue.
Described inflatable screw rod comprises conical head, intumescent sheet, screw rod, nut, and screw rod and conical head are connected as a single entity, intumescent sheet is that a ring-like thin slice encloses and binds round in screw rod and conical head joint, and wherein said conical head is the wedge shape conehead.Have groove on the described intumescent sheet.
The utility model has the advantages that simple in structure, easy for installation, rapid, anchoring is reliable, installation efficiency is improved greatly, satisfied the requirement of dismounting repeatedly again.
Description of drawings
Accompanying drawing 1 the utility model chemical glue tubular construction schematic representation;
Accompanying drawing 2 the utility model structural representations;
Accompanying drawing 3 is the A-A sectional view;
Embodiment
The utility model feature and other correlated characteristic are described in further detail by embodiment below in conjunction with accompanying drawing, so that technician's of the same trade understanding:
As Figure 1-3, label 1-9 represents respectively: chemical sebific duct 1, wedge shape conehead 2, intumescent sheet 3, intumescent sheet groove 4, screw rod 5, nut 6, pad 7, afterbody mounting groove 8, colloid mixture 9, aggregate 10.
Present embodiment is made of chemical sebific duct 1 and inflatable screw rod, contain in the chemistry sebific duct 1 colloid mixture 9 is housed, inflatable screw rod is made of wedge shape conehead 2, intumescent sheet 3, screw rod 5, nut 6, pad 7, wherein screw rod 5 is connected as a single entity with conical head 2, intumescent sheet 3 is a ring-like thin slice, this sheet encloses and binds round in screw rod 5 and conical head 2 joints, has intumescent sheet groove 4 at intumescent sheet 3.
Present embodiment is when using, the conehead of wedge shape conehead 2 is a wedge shape, makes it to be beneficial to blend the glass sebific duct, and colloid mixture 9 can flow to screw rod 5 by the groove 4 of intumescent sheet 3, utilize the aggregate 10 in the sebific duct 1 to prop up intumescent sheet 3, screw nut 6 and make wedge shape conehead 2 indentation intumescent sheets 3, bear imposed load thereby make intumescent sheet 3 distendings prop up the hole wall frictionally, this is a mechanism of intumescence, after treating colloid 9 final set, screw rod 5 bonds together with concrete wall, and this is a chemical adhesive mechanism, thereby realizes its double action.
Break up sebific duct 1 with screw rod 5 hammerings rotation, install at once by anchor, screw nut 6, this moment, its action principle was as expansion anchor by expansive force opposing external force, and along with solidifying of anchor adhesive, its action principle adds chemical anchor bolts as expansion anchor.Not only easy for installation but also anchoring is reliable, discard to fall the defective of the two simultaneously.
Present embodiment mechanism is the double action of expansion bonding, and obviously under the prerequisite that does not break away from the utility model protection domain, present embodiment can also following several mode of structure.
1. the wedge shape conehead 2 in the present embodiment is replaced with the crosspoint tip screwdriver head form, also can reach the effect same with present embodiment.
2. the chemical sebific duct 1 of present embodiment also can directly adopt concrete pore passage, injects anchor adhesive during installation in the hole, inserts with the common expansion anchor in aperture again, screws at once also and can realize the present invention.
3. when the screw rod 5 of common expansion anchor be steel pipe, can offer hole for injecting glue at its afterbody, crab-bolt screw in place after, still can inject the chemical anchoring glue hole depth place that goes directly by screw rod 5 afterbody apertures.
4. also can adopt ordinary cartridge formula expansion anchor and chemical anchor bolts chemical sebific duct combination accessory, conehead adopts wedge type, uses when installing and can blend chemical sebific duct, sleeve is covered with decorative pattern outward, and is by sleeve expansion, bonding by sleeve and concrete hole wall again simultaneously.
Claims (5)
1. an assembly anchor bolt comprises chemical sebific duct, it is characterized in that the screw rod that is used with chemical sebific duct is inflatable screw rod, and this chemistry sebific duct refers to the pipeline that can place chemical glue.
2. a kind of assembly anchor bolt according to claim 1, it is characterized in that, described inflatable screw rod comprises conical head, intumescent sheet, screw rod, nut, screw rod and conical head are connected as a single entity, intumescent sheet is that a ring-like thin slice encloses and binds round in screw rod and conical head joint, and wherein said conical head is the wedge shape conehead.
3. a kind of assembly anchor bolt according to claim 2 is characterized in that, has groove on the intumescent sheet.
4. a kind of assembly anchor bolt according to claim 1 is characterized in that, is placed with chemical glue in the described chemical sebific duct.
5. a kind of assembly anchor bolt according to claim 1 is characterized in that, has hole for injecting glue on the described inflatable screw rod.
