[0002] 1. Field of the Invention
[0003] This invention belongs to the field of means for attachment for construction blocks and particularly crossed tics therefor.
[0004] Our research among patents revealed some systems that caught our
attention.
[0005] US 8,181,414 (Web Structure fir Insulating Concrete Block) filed on 2010/09/23 by David Michael Garrett (US) shows means of attachment of two parallel panels comprising web structures 16 placed perpendicularly to the panels in the space between them with means of interconnection.
US 7,415,804 Emulated Concrete Form Having Welded Tie) filed on 2003/09/04 by Jerry D. Coombs et al. (US) shows metal wire ties comprising horizontal and vertical members used to interconnect two opposing parallel panels.
[0007] 2. Objectives and Advantages
[0008] Light weight, concrete, rock, or wood blocks need a frame which maintains a spaced apart position of the construction blocks and avoids shifting when the blocks are subjected to oscillating during wind, storm, tornadoes, landslides, or earthquake. The present invention provides means for attaching blocks two by two and keep them stable in a spaced apart position resisting shear forces. The crossed ties interconnecting blocks are comprising a rectangular shape wherein opposite corners arc joined by straight links to avoid shifting when the blocks are subjected to oscillating. Pegs arc provided to mesh with critical positi ons in the blocks for stable junctions.
[0009] With such attachments, the blocks arc made with notches on upper and lower surfaces of the blocks and on their sides. The crossed ties arc then pressed tight into the notches of the block. Means of lifting can be provided to lift an assembly of blocks interconnected with crossed ties.
[0010] The present invention will be further understood from the following
description with reference to the drawings wherein like numbers refer to like parts for easy identification. BRIEF DESCRIPTION OF THE DRAWINGS

FIG.l shows an assembly 20 of blocks showing blocks 22,22' comprising exterior face 27,27' and interior face 25,25' comprising a number of notches 24 and a channel 26. A crossed tie 28 comprising a rectangular frame 30 has end members 31, side members 32, a pair of diagonal members, straight links 34, and a pair of means of lifting 36 acting as means of handles. A center transversal member 38 is also present. Pegs 40 complete end and center members, and they enter the notches 24,24' to ascertain a proper junction with each block 22,22'. The in between blocks 48 are filled with an insulated material to provide sound barrier as well as thermal shield. [0016] FIG.2 shows a block 22 with an interior face 25 and an exterior face 27. The block is provided with notches 24 all around the interior face and a channel 26 intended to receive rods to strengthen the whole assembly of blocks, when erecting a wall.

transversal member 38, diagonal straight links 34, and means of lifting 36.
[0018] FIG.4 shows a crossed tic 29 with round pegs 42 and a retainer hook 50 to attach rubber rings. Channels 52 are made in rectangular-shape end members 31 to pass the means of lifting 36 through, thus avoiding gap between two interconnected blocks pressed aside against each other, when erecting wall construction.
DESCRIPTION OF EMBODIMENTS
[0019] An assembly of at least two parts of blocks made of light weight, concrete, wood, or rock, parallel, angular, radius, T-shape, shaft-shape. Between the parts, a void channel or rilled channel with an insulating substance like mineral wool and/ or roxul or blown in spray insulation. The channels provide a sound barrier and insulati on. Crossed ties are used such as means of attachment to prefix or preassemble the blocks together in the construction of a double wall structure. The crossed ties are in a shape of a rectangle wherein opposite corners are joined by straight links for avoiding shifting when the blocks are subjected to oscillating during wind, storm, landslides, tornadoes, hurricanes or earthquake. The pegs are in a rectangular or a circular shape.
[0020] With such attachments, the blocks are made with notches on upper or low T er surfaces of the blocks and on their sides. The pegs of the crossed ties are then pressed tight into the notches of the block. The crossed ties are provided widi means of lifting, in a snake shape, to lift the assembled blocks with crossed ties fastened. [0021] Two blocks joined with means of attachment as crossed ti es could be of different materials, such as a marble block joined with a rock block, or a cement block joined with a colored cement block or a wood block. The rows of blocks are held by passing through metal rods which position any two blocks in a series to form a wall, with armoured rcbar rods.
[0022] The crossed ties can comprise a retainer hook destined to hook on rubber rings to keep parallel back and front blocks together when erecting sound barrier walls.
[0023] More precisely, our invention comprises a combination of parallel spaced apart blocks 22,22' interconnected with a rectangular-shape crossed tie 28. Each block comprises an interior face 25,25' comprising means of notches 24 on the periphery. The crossed tie 28 comprises:
• four pegs 40 extending out of the periphery and being pressed into the
notches 24 to interconnect both blocks;
• straight links 34 joining opposite corners of the rectangular-shape, thus
maintaining firmly the spaced apart position of the blocks and avoiding shifting of the blocks; and
• a center transversal member 38 to further reinforce the the to resist shear forces when blocks are subjected to oscillating; where, on the transversal member, pegs 40 extend out of the periphery, to be pressed into notches 24 of the blocks.
[0024] The pegs are provided to mesh with critical positions in the blocks for stable junctions.
[0025] The pegs may be round pegs 42 or flat pegs 41.
[0026] Means of lifting 36 are used in the crossed ties to lift the whole combination of interconnected blocks. The means of lifting are snake-shape transversal members tied by their ends. Channel 52 are made in rectangular-shape ends 31 to pass the means of lifting through, when one lifts them up, thus avoiding a gap between two interconnected blocks pressed aside against each other when erecting wall construction.
[0027] The crossed tics may comprise a retainer hook 50 to hook on rubber rings for keeping parallel back and front blocks together when erecting sound barrier walls.
[0028] The crossed ties are preferably made of plastic.
[0029] It is to be clearly understood that the instant description with reference to the annexed drawing is made in an indicative manner and that the preferred embodiments described herein are meant in no way to limit further embodiments realizable within the scope of the invention.
