Abstract

Abstract A masonry construction device useful for uniformly spacing adjacent masonry elements, for reinforcing the elements, and for tying the elements to an adjacent structure, comprises a pair of spaced sawtooth shaped members having a plurality of bearing surfaces for engaging the adjacent masonry elements, and a bridging member connected between the sawtooth shaped members such that the device has a substantially U-shaped configuration.

Claims Analysis

Total Claims: 13
Claim 1
Independent Claim 268 words
An interlocking spacer device adapted to be disposed between adjacent masonry elements for spacing the masonry elements a predetermined distance apart, the device being U-shaped and being formed by first and second elongated members which are corrugated over substantially their entire length and spaced apart in respective first and second parallel planes, and by a third straight member connected to the first and second members and extending substantially perpendicular to the first and second planes, the third member being formed of two telescoping sections so that the spacing between the first and second members may be varied, each member comprising a rod of circular cross-section and uniform diameter, and the first and second members each being formed to have in its respective plane a sawtooth shape which provides, on one side of the member, a plurality of first ridges and valleys alternating along the length of the member and, on an opposite side of the member, a plurality of second alternating ridges and valleys, the first and second ridges being spaced apart in the plane of the member by said predetermined distance and providing a plurality of bearing surfaces for engaging and spacing corresponding first and second adjacent masonry elements, and wherein the diameter of said members is less than a distance in said planes between the ridges and alternating valleys such that a member of another U-shaped device may cross one of the first and second members at an angle and be received within a valley between adjacent ridges to interlock the U-shaped devices together with the ridges of said U-shaped devices at substantially the same levels.
Claim 2
Dependent Claim 268 words
An interlocking spacer device adapted to be disposed between adjacent masonry elements for spacing the masonry elements a predetermined distance apart, the device being U-shaped and being formed by first and second elongated members which are corrugated over substantially their entire length and spaced apart in respective first and second parallel planes, and by a third straight member connected to the first and second members and extending substantially perpendicular to the first and second planes, the third member being formed of two telescoping sections so that the spacing between the first and second members may be varied, each member comprising a rod of circular cross-section and uniform diameter, and the first and second members each being formed to have in its respective plane a sawtooth shape which provides, on one side of the member, a plurality of first ridges and valleys alternating along the length of the member and, on an opposite side of the member, a plurality of second alternating ridges and valleys, the first and second ridges being spaced apart in the plane of the member by said predetermined distance and providing a plurality of bearing surfaces for engaging and spacing corresponding first and second adjacent masonry elements, and wherein the diameter of said members is less than a distance in said planes between the ridges and alternating valleys such that a member of another U-shaped device may cross one of the first and second members at an angle and be received within a valley between adjacent ridges to interlock the U-shaped devices together with the ridges of said U-shaped devices at substantially the same levels.
Claim 3
Dependent Claim 43 words
In combination, a plurality of spacer devices in accordance with claim 1, wherein the first and second members of a first one of said devices cross the first and second members of a second one of said devices to interlock such devices together.
Claim 4
Dependent Claim 266 words
A masonry construction comprising a plurality of masonry elements, a plurality of spacer devices disposed between the masonry elements for uniformly spacing adjacent masonry elements a predetermined distance apart, and a bonding material filling the spaces between the masonry elements to tie the masonry elements together with said devices therebetween, each spacer device being U-shaped and comprising first and second spaced elongated members which are corrugated over substantially their entire lengths in respective first and second substantially parallel planes which are normal to facing surfaces of the adjacent masonry elements between which the spacer device is disposed, and a third member connected between the first and second members, the first, second, and third members having a circular cross-section and a uniform diameter, and the first and second members each providing in their respective planes a plurality of first and second ridges spaced said predetermined distance for engaging and spacing corresponding first and second adjacent masonry elements said predetermined distance apart, the ridges alternating with valleys along the length of each member, and the diameter of the members being less than the spacing, in the direction of said predetermined distance, between the ridges and valleys, and a first one of said plurality of spacer devices being located with respect to a second one of said plurality of spacer devices such that a member of said first spacer device crosses one of the first and second members of the second spacer device with such member of said first spacer device received between adjacent ridges of the second spacer device to interlock the first and second spacer devices together.
Claim 5
Dependent Claim 266 words
A masonry construction comprising a plurality of masonry elements, a plurality of spacer devices disposed between the masonry elements for uniformly spacing adjacent masonry elements a predetermined distance apart, and a bonding material filling the spaces between the masonry elements to tie the masonry elements together with said devices therebetween, each spacer device being U-shaped and comprising first and second spaced elongated members which are corrugated over substantially their entire lengths in respective first and second substantially parallel planes which are normal to facing surfaces of the adjacent masonry elements between which the spacer device is disposed, and a third member connected between the first and second members, the first, second, and third members having a circular cross-section and a uniform diameter, and the first and second members each providing in their respective planes a plurality of first and second ridges spaced said predetermined distance for engaging and spacing corresponding first and second adjacent masonry elements said predetermined distance apart, the ridges alternating with valleys along the length of each member, and the diameter of the members being less than the spacing, in the direction of said predetermined distance, between the ridges and valleys, and a first one of said plurality of spacer devices being located with respect to a second one of said plurality of spacer devices such that a member of said first spacer device crosses one of the first and second members of the second spacer device with such member of said first spacer device received between adjacent ridges of the second spacer device to interlock the first and second spacer devices together.
Claim 6
Dependent Claim 25 words
A device according to claim 3, wherein the dimensions of the devices are less than the dimensions of the facing surfaces of said masonry elements.
Claim 7
Dependent Claim 14 words
A construction according to claim 3, wherein the devices are formed of steel wire.
Claim 8
Dependent Claim 13 words
A construction according to claim 3, wherein the devices are formed of plastic.
Claim 9
Dependent Claim 35 words
A masonry construction in accordance with claim 3, wherein one of said devices projects beyond the sides of said masonry elements to enable the third member of said device may be secured to another structure.
Claim 10
Dependent Claim 17 words
A masonry construction in accordance with claim 3, wherein said masonry elements comprise stones of different sizes.
Claim 11
Dependent Claim 38 words
A construction according to claim 3, wherein said ridges on each side of the first and second members are spaced the same distance apart along the members, and the second ridges are located midway between the first ridges.
