Definitions

  • a frangible ampoule can be inserted into a hole in which an object is to be anchored, and contains a first component of a two-component adhesive.
  • a second component of the adhesive is externally adjacent the ampoule and so arranged as to be intermixable with the first component upon breakage of the ampoule.
  • the present invention relates to adhesive cartridges, and more particularly to adhesive cartridges which utilize a two-component adhesive for the purpose of anchoring an object in a hole in a wall or the like.
  • an adhesive cartridge for anchoring of an object in a hole which cartridge briefly stated comprises a frangible ampoule adapted to be inserted into a hole, and a two-component adhesive.
  • a first component of the adhesive is accommodated in the ampoule, and a second component of the adhesive is externally adjacent the ampoule and so arranged as to be intermixable with the first component upon breakage of the ampoule.
  • the arrangement of the second component is such that it is permeable by and/or penetrable by the first component when the ampoule is broken. This assures a good admixture of the two components, because when the breakage occursas a result of the insertion into the hole of a special tool or else of the object which is to be anchored in the holethe adhesive component accommodated in the ampoule will necessarily be pushed from inwardly in outward direction, that is through the second adhesive component, so that a proper and uniform admixture will be obtained.
  • One of the components may for instance be in the form of a paste, and may be applied to the outer wall of the ampoule in form of a helical strip or the like.
  • the one component that is the outer one, may be in form of a layer or coating which is provided around the wall of the ampoule.
  • fibrous material which surrounds the outer or second component, or which is partly or completely impregnated with it.
  • the one component that is here the outer component
  • the one component is applied over a large area of the ampoule containing the other component. This is of great value in assuring proper admixture of the two components when the ampoule is broken.
  • the cartridge may utilize an outer envelope surrounding the ampoule and accommodating the second component.
  • This arrangement assures that the cartridge can be stored over prolonged periods of time without having to fear any damage or other deleterious influence upon any of its components. It is also desirable that steps be taken to prevent a shifting of the outer or second component relative to the ampoule in the event that the cartridge should be dropped or otherwise impacted.
  • This can be accomplished in an advantageous manner by providing the outer surface of the ampoule, and/or the inner surface of the envelope, with recesses which advantageously are more or less evenly distributed over the entire surface.
  • Such recesses may be depressions, they may be grooves such as helical grooves, or the like. This also facilitates the insertion of the ampoule into the envelope, because the second component is now located in these recesses and cannot be displaced or damaged as the ampoule is inserted into the envelope.
  • FIG. 1 is a partly sectioned side view of a cartridge according to one embodiment of the invention.
  • FIG. la is an enlarged sectional view in axial direction through a portion of one end of the cartridge in FIG. 1;
  • FIG. 2 is a partly longitudinally sectioned view of a further embodiment of a cartridge according to the invention, accommodated in a bore hole;
  • FIG. 3 is a section taken on line III-III of FIG. 2, with the wall having the bore hole therein being omitted;
  • FIG. 4 is a view of a further embodiment of the invention.
  • FIG. 5 is a view analogous to FIG. 4 but illustrating an additional embodiment of the invention.
  • FIG. 6 is a view of still another embodiment of the invention.
  • FIGS. 1 and la DESCRIPTION OF THE PREFERRED- EMBODIMENTS
  • an adhesive cartridge 1 having an outer envelope 2 which is shown in broken lines and may be made of glass or another suitable frangible material, and an inner ampoule 3 which also may be made of glass or another suitable frangible material and which is shown in broken lines.
  • the ampoule 3 accommodates the first or inner component 5 of a twocomponent adhesive, which is shown fragmentarily at 4.
  • the inner wall of the outer envelope 2 is provided with the second outer adhesive component 6 in form of a helical strip applied to this inner surface.
  • the spaces 7 between the individual convolutions 12 of the helical strip assure and make possible a proper admixture of the two components 5 and 6 because, when the inner ampoule (and of course the outer envelope) are broken, the component 5 can press outwardly uniformly through the spaces 7 and become admixed with the component 6.
  • FIG. 2 the cartridge is identified with reference numeral 1a and has an outer envelope 2 and an inner ampoule 3.
  • the latter again accommodates the adhesive component 5, whereas the adhesive component 6 is accommodated in a helical recess 12 provided in the outer wall of the outer envelope 2. This assures retention of the paste-like component 6 against displacement, especially during storage and transportation of the cartridge where otherwise this would not always be assured.
  • FIG. 2 also shows the cartridge la accommodated in a hole 8 formed in a wall or the like, and in which an anchoring member 9 is to be inserted and retained by the adhesive action of the two admixed components 5 and 6.
  • the insertion of the anchor 9, which results at the same time in the breaking of the envelope 2 and the ampoule 3, can be effected by the diagrammatically illustrated tool 10.
  • the fragmentarily shown apertured sleeve 11 facilitates further a uniform admixture and distribution of the two components 5 and 6. It will be appreciated that as the anchor 9 is inserted into the hole, the envelope 2 and the ampoule 3 will be broken, resulting in admixture of the components 5 and 6 and even distribution over the wall bounding the hole 8. This v is further facilitated, as pointed out before, by the sleeve 1 1.
  • FIG. 4 shows a cartridge lb utilizing only an ampoule 2 which accommodates the component 5.
  • the outer circumferential surface of the ampoule 2 is coated with the component 6a. This is a particularly simple construction requiring only the ampoule 2.
  • the cartridge is identified with reference numeral 1a.
  • This embodiment is advantageous if not enough of the second component can be applied in form of a coating, as in FIG. 4.
  • a single ampoule or envelope 2a is utilized, but here it is surrounded by a fibrous sliver or material V which can either be wrapped over a coating of the second component 6, or which can be impregnated with the second component.
  • the sliver V can be thick enough so that it can accommodate in its pores or interstices enough of the component 6 to make up the required quantity thereof.
  • FIG. 6 finally, shows in more detail the use of the perforated sleeve 11.
  • the sleeve is here shown fragmentarily in an axial section and the cartridge 1b is shown partially pushed into it.
  • a comparison of FIG. 6 with FIGS. 2 and 3 shows that the outer diameter of the sleeve 11 is accommodated to the inner diameter of the hole 8, and the inner diameter of the sleeve 11 to the outer diameter of the cartridge 1a or 1b.
  • the sleeve 11 has a multiple purpose, namely on the one hand to protect the wall surrounding the hole 8 from damage and undesired enlargement, which might occur on insertion of the cartridge and/or the anchoring element 9 if the material of the wall is of a readily damagable type, for instance porous concrete or the like.
  • sleeve 11 assures an even distribution and admixture of the components 5 and 6 over the entire circumferential wall bounding the hole 8, as already pointed out earlier. This is particularly advantageous if the wall bounding the hole 8 is not smooth but has voids or the like.
  • An adhesive cartridge for anchoring of an object in a hole comprising an outer frangible ampoule adapted for insertion into a hole and having an inner circumferential surface; an inner frangible ampoule received in said outer ampoule with radial clearance and having an outer circumferential surface; a first component of a two-component adhesive accommodated in said inner ampoule; and a strip of a second component of said adhesive helically convoluted on one of said surfaces, surrounding said inner ampoule and extending.
  • An adhesive cartridge for anchoring an object in l a hole comprising an outer frangible ampoule adapted said inner ampoule; and a strip of a second component having convolutions located in said recesses and spaced apart from one another so as to facilitate intermixing of said components upon fracturing of said ampoules.
