Abstract
Abstract Apparatus for anchoring slabs, such as natural stone slabs, masonry wall blocks or the like, to an anchorage base, e.g. a building, comprising an angular holder having two spaced struts. Each strut includes a vertical holding leg and a horizontal supporting leg. The struts are arranged perpendicular to the surface of the anchorage base. The struts are braced together and combined with an anchor for anchoring the holder in the base, and a support member for supporting the slabs or the like. The holder and connected elements can be mass produced inexpensively by punching or stamping flat material, require no complex shaping work, exhibit a minimum weight with high load-bearing capacity, and can be easily adjustable.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
203 words
An apparatus for the anchorage of loads such as slabs or the like to an anchorage base, comprising: (a) a holder assembly comprised of a pair of separately formed, spaced, angular shaped holders, each holder comprising a flat vertical holding strut adapted to be positioned generally perpendicular to the surface of the anchorage base, and an integrally formed flat, generally horizontal supporting strut extending generally perpendicular to said vertical strut toward the load to be supported, said holders being spaced from and generally parallel to each other, said vertical holding struts including rearwardly projecting means in the lower regions thereof for contacting said anchorage base; (b) means for securely bracing said holders in their spaced, parallel position, said bracing means comprising a pair of spaced, parallel bearing plates positioned between and secured to said horizontal supporting struts; (c) anchoring means operatively connected to said holders for anchoring the same to said base; and (d) generally horizontally outwardly extending load support means operatively connected to said bearing plates and thus to said horizontal supporting struts of said holders, said load support means being adapted to support such loads and transfer, through said bearing plates and said holders, the force thereof to said anchorage base.
Claim 2
Independent Claim
203 words
An apparatus for the anchorage of loads such as slabs or the like to an anchorage base, comprising: (a) a holder assembly comprised of a pair of separately formed, spaced, angular shaped holders, each holder comprising a flat vertical holding strut adapted to be positioned generally perpendicular to the surface of the anchorage base, and an integrally formed flat, generally horizontal supporting strut extending generally perpendicular to said vertical strut toward the load to be supported, said holders being spaced from and generally parallel to each other, said vertical holding struts including rearwardly projecting means in the lower regions thereof for contacting said anchorage base; (b) means for securely bracing said holders in their spaced, parallel position, said bracing means comprising a pair of spaced, parallel bearing plates positioned between and secured to said horizontal supporting struts; (c) anchoring means operatively connected to said holders for anchoring the same to said base; and (d) generally horizontally outwardly extending load support means operatively connected to said bearing plates and thus to said horizontal supporting struts of said holders, said load support means being adapted to support such loads and transfer, through said bearing plates and said holders, the force thereof to said anchorage base.
Claim 3
Dependent Claim
23 words
The apparatus as claimed in claim 1, wherein said horizontal supporting struts and said vertical holding struts are punched out of flat iron.
Claim 4
Dependent Claim
22 words
The apparatus as claimed in claim 1, wherein said vertical and horizontal struts of each holder are in the same vertical plane.
Claim 5
Dependent Claim
31 words
The apparatus as claimed in claim 1, wherein at least one of said bearing plates is formed with a threaded opening through which a threaded section of said support means extends.
Claim 6
Dependent Claim
49 words
The apparatus as claimed in claim 4, wherein a threaded bearing in the form of a freely rotatable adjustment screw nut is provided between said bearing plates and in threaded engagement with a threaded section of said support means, whereby said support means can be adjusted inwardly or outwardly.
Claim 7
Dependent Claim
27 words
The apparatus as claimed in claim 1, wherein said bearing plates are inserted firmly on said supporting struts by means of apertured extensions formed in said plates.
Claim 8
Dependent Claim
23 words
The apparatus as claimed in claim 6, wherein certain of said extensions have oblique edges running upward and inward toward the supporting struts.
Claim 9
Dependent Claim
28 words
The apparatus as claimed in claim 1, wherein, in the rear region of said supporting struts, a reinforcement plate is inserted in recesses formed in said supporting struts.
Claim 10
Dependent Claim
78 words
The apparatus as claimed in claim 1, further including means for vertically adjusting said holders, said adjusting means comprising a setting plate in the form of a continuous wedge plate with one border bent toward said holders, said holders being provided with supporting recesses on the edges of said vertical holding struts facing said base, said recesses receiving the edge of said border, said wedge plate having a lower edge which runs at an angle to the horizontal.
Claim 11
Dependent Claim
19 words
The apparatus as claimed in claim 9, wherein said border is bent at an angle of less than 90°.
Claim 12
Dependent Claim
31 words
The apparatus as claimed in claim 1, wherein said projecting means comprises a projecting lug formed in the lower region of each vertical holding strut for contact with the anchorage base.
Claim 13
Dependent Claim
19 words
The apparatus as claimed in claim 8, wherein said projecting lugs means comprise formed on said rear reinforcement plate.
Claim 14
Dependent Claim
31 words
The apparatus as claimed in claim 1, further including a clip extending over the vertical holding struts, said clip being formed with an elongated recess through which said anchoring means extends.
Claim 15
Dependent Claim
29 words
The apparatus as claimed in claim 1, wherein said load support means includes a flat mount portion having mounted theron a holding pin for the slabs to be supported.
