elated ~atents-
There are several patents concsrning the recycle of used tires such as ~aXinq liquld or solid ruels
20or shrstding tires to mix them with asphalt,or making dikes or dams by lyirg thsm ~lat and using thom as
soil retainers but the invention which makss the object of this patent is quits differsnt ~rom these products
becaus- of its unique design which make it useful for a great deal of applications in the military and in
the civil sectors without the need for heavy equipmer.t such as shreaders; fu~hormore,it will use a much
grsater number of tires thus reducing the environmental risks involYed in storing them.

~ack~round o~ th~ invention
The present invention pertains to solving A growin~ ers~ironmentQl threat which is fhe masslve
stockpilin~ of used tirss resulting in uncontrollable tire fires very dstrimen.tal to the er.vironment.~qkin~
good economic use of old tires will reduce this stockpiling and the risk associqted with it Even though thess
tires will be Srread all over the country they will represent a much lssser risk than b?ing concentrated
in monstrous quantities in the same area.
Descri~tion~ he.Prior art
To my knowledge there does not exist any composite material whic~ uses recyc~ed or ~eFsctive tires
in this manner.P.efer to the .section entitled "P.elated patents" abo~e for further dstails.
S~vm~v of the invention:
Tire strings:(dw~#A-#D)
This invention relates to a new composite material called in this ratent "rIRE ~I~IN~" used for
various applications or constructions illustrated herewith.
All applications described use conventional materials which when they reach the end of their life
cycle create more garba~e to dispose of.The advantage of the tire string over the latter is that its life
expectancy in so~e cases may be longer;it reduces significantly if widely ussd the pressnt tlrs disF~osAl
problem and will not gensrate more garbage than presently exists.On the other hand the labour cost for the
manufacture of such structures will be offset by the lower cost o~ the material The greatest ad~lntnge is
to the environment and the land presently used to stockpile old tires which will be free for other uses
particularly for countries which to not have much land to spare.
Tire strinqs consist of old or reject tires strung together with a or several cablss with thre_dsd
ends (steel nylon or m~de of any other material) or with chains w-th threaded sye-bolts q~t each end clamped
bstween two steel plates or any other material ref. dwg~D.(Note :the support for the tires can be obtainsd
by other means such as steel rods F~ipss or cables locatsd outside the tires (ex.tire rac~.s d-g#4~ or

6Q any other type of structural member using steel or uood beams.The threaded ends ~male or female;ref.dug#B)
are used for clamping and installation purposes.Other types of ~astening could be utilized such as steel
wed0es.The tires are coated uith a bonding agent such as asphalt ,tar, pitch, resin, stucco, mortar,
glue,epoxy,polymers,cement,urethane or any other type of bonding agent thersof uhich can be covered with
an aggregative m~terial such as granular colored stones used on roof shingles, small river stones, crushed
glas~, glass pellets made from recycled wine bottles, gravel or any other type of aggregative material
thereof or any decorative coating such as stucco,paint3,fiber glass, resins,polymsrs or roof sheeting with
colored granules .In the case of military usage, camouflage paints or nets or any other type thereof could
be used. ~ood studs or steel bars are inserted in the tires to preserve their original shape when they are
clamped together . me studs are nailed to keep them in place inside the tires and the steel bars are
bolted(ref.dwg #1-#~).Dspending on the wall height desired, one or more tire strings are mour.ted betueen
tuo colt,tmns which are made of steel "T" or ~H" beams,wood posts, concrets pillars or any other type
thereof.The steel beam i5 slotted (ref.dug#l,detail with steel beam) to enable the bolting of the tire
strings . As for the wood posts or concrete pillars,eteel brackets (ref .dwg~ ,detail with wood post ) are used
to hold the tire strings in placs.The columns (steel or wood~ are rammed into the ground or eath-covered
like electrical postEt or bolted on concrete foundations or poured in concrete . Tires can be oriented at
any angle in order to reducs the thickness of the as6embly ~ref.dwg#E~ this is accomplished by using wood
or welded steel plate assemoly end fillsr pieces which orient tires at any angle.Tire strings can be mounted
horizontally or vertically.Also filler material can be inserted inside the tires to improve accoustical
properties such as urethane,sand,any type of insulating foam or wool,concrete or any other type of material
~9 thereof . (ref .dwg#6~Filling is accomplished through holes in the endplates uhich are plugged with
threaded,bolted or wslded plugs.
To hold studs aligned from tire to tire, "~"shaped nails are used to clamp t~Q cables to the wood spacers
either press or loose fit ~ref.dwg#C~.~oose fit sssembly combines clamping action of endplates and proper
EstUt alignment . The use of "~"shaped nails crimping the cable can replace the clamping action of end
platss,thUs end plates are screwed to wood spacers in the end tires (ref.dwg#C vieu "B").Tire strings car.
oe clamped with female cable ends ar.d flat-head bolts to have flush ends which facilitates the assembly of
noise barrier walls to prevent air gaps caused by clamping nuts which protude and must be masked uith forenz
or plywood ref . dwg#B .

Noise barrier walls:
Noise barrier ~lalls consist of se~eral rows of tire strin~s bolted to columns.Waterproof plrwood
or sheets of recycled rubber are installed at each end with holes to enaole the passage of cables and fill
the gap cre?ted by the clampin~ nuts.(ref.dr!g#1 and#3).A roren~ ~ref.dwg#4A) or a tire ali~ned with sach
row at each end ~ref.dws#4C) can also be bolted to columns to fill the gap in lieu of ths plywQQd or the
use of female threaded cabls ends eliminates the ga~ and the need for filler material altogether.The strings
are bolted to columns with two ~emale cable ends ;the middle cable holds the strin~ to~ether with flat-head
bolts.~ref.dw~#4A).
Cables can be eliminated r1ith a tire rack mQdel in which end plates are screwed to end-tire studs ~sracers)
and clampin~ bolts are used with threaded holes in beam flanges ~ref.dwg~4B) to clamps tires together.
100 "V"shaped pieces of wQ~d ~ex.6x6 cut lon~itudinallr through tWQ opPosite corners (diagonally)) or vinyl
strips or any other filler and decorative material thereof are installed between tire rows for all barrier
wall models;they can be directly screrled to tires ~ref.dw~#~A) or to plywood end pieces ~ref.dw~#3).
Another model uses roQf sheeting with color granules.Strings ~re individually wrapped or draped together.
(ref.dwg#4)
Roadrail~:
Roadrails are made with a single row of tires(dwq#5).The ad~antage of such ? system is that the wood
posts are installed at greater distances thus reducin~ the nLmber re~uired.The posts are joined with the
tire string cables which transmit the 'orces of a colliding car to all the posts.The tires hold ths cables
110 togethsr and act as a barrier to hold the car back and prevsnt it from rolling over the cables or from
capsi7ing.This combination of tires and cables will have better shock absorption characteristics than the
conventional roadrail because it will have less tendency to be crushed dorm compared to the existing steel
pannel and WoQd post model and the cables will distribute the forces to Q greater r.umber of nQsts;also the
stsçl brackets to which cable ends are bolted can be made in one piece the bracket acts as a chain link
tying individual tire strin~s together;hence a tire string is not solely supported by one post but by all
posts and all other tire strings.Furthermore,to increase the strength of the asse~bly,wood posts are replaced
with concrete rillars;the latter are well protected by the tire strings th.l!s su~plying ri~idity to the
roadrails without increasin~ the risk oF damage or injury to a colliding car or ~n its passengers.

Tires strings are sQndfàlled to increase mass and inertia for increased stopping power.Tire strinqs can
120 also rest on the ground ~in s!hich case larger si2ed tires are used) and be strung to posts which are
installed at even qreater dictances.Earth ~ackinq could also ~e provided for increassd stopping powsr and
springs could be added for better shock absorption.(reÇ.dwq#5A).~or dead end applications, tire strinqs are
tied to an underqround concrete base with the use of eye bolts installed on cable ends; a cable and sprinq
arrangement ties the tire strinq to the concrete base( this arrangement is al~o used for roadrails with or
without the spring attachment~.This greatly enhances the shock absorption capabilities and integrety of the
system will be maintained throughtout the collision because of the solidity pro~Jided by the concrete
base.This syst~m behaves somewhat like the braking cables used on the decks of aircraft carrier
ships.(ref.dWg#5D)
In curves, strings ars made in shorther segments in order to follow the curved path (ref.dwq#58) or tire
130 spacers on the concave side are mads shorter and end spacers are wedgs shaped to comprsss to a greater
sxtsnt the concave side.(reÇ.dwg#5B-#5Ç)
Note:Hnndrail~ or ~uardrail~ are constructed in the same fashion as roadrails.
~ilitary barricades:
For the military, barrier walls for infantry mon and women are quickly installed with such a
material.Tire strings are prefilled with sand by puncturing holec on the sole of the tires ,filling them
with sand and patching the hole afterward or by inserting sand into them through the ~nd plates
(ref.dwg#6).8everal rous could be installed; some rous could have empty tires and have a tap hole on the
end plate to enable the quick inssrtion of a liquid conbustible material such as gasoline or a liquid
149 explosive to turn the row of tires into a Banqalore torpedo.This device could be inflamed to act as a fire
and smoke barrier or could be detonated locally or remotsly to Permit cafer retrieval of our troops while
infllcting casualtiss to ths ensmy.
For fast installation and minimal civil work tire strings ars assembled with female cable ends slith flat-
head bolts thus enabling butt end to end installations ;posts ars not rsquired and ars replaced uith woQd
wedgss or small steel or wood stakes or any other means of preventinq tire strinqs from rolling (dwg#6A).
Rtr$n~s are rolled fro~ transport trucks into their proper location s~hich facilitates the work compared to
~and bags or digging trenches.Truck tires are used for higher barricades;earth backinq is added for increased
protection against bullet penetration.
Also for ths military,sand fillsd barriers could be installed around heaYy artillery
150 equipment in a bunker typs fashion protectinq soldisrs from noiss,artillary prsssure and enemy fire.These

bu~kers could be installed and dismantlsd ~uickly.(ref. noise-b3rrier walls dun#1-#3)
Hindbreakers:
This neu matsrial is also used for windbreaker walls.Spacer pieces of wood or steel (r~f.dwg~7~
which could also be pieces of ~4 uood screued between tires hori70ntally (not illustrated) are inssrted
betueen the tires at a certain frequency which prevents the uind frsm hitting R solid uall de~lscting over
it and falling back to ground level fifty or one hundred feet further thus sweeping snow onto the
roadway.~.7ith the spacers the wind seeps through the voids loosing energy tnuS reducing the ~sts of uind
and snow sueeping onto the road.Another model of windbreaker uses different tire si~es (13 in.-l~in.
16g combination)thus creating voids betueen rows instead of using spacers.
Tunnel shaPed noiss barrier or small arm firing range:
P.ound or half-round shaped constructions (ref.dwg~78) are made and used as small arms firing rang~s
or as noise barriers.2his is accomplished uith inverted ~" shaped structures ~such as bent "~' or I' steel
bsams round or s~uare steel tubes) placed at intervals from five to ten feet ~more or less) to which tire
strinns are bolted.2he tires are sand-filled to increase mass and resistance to bullet penetration or filled
with any other type of insulating foam or material thereo4 in the case of a noise barrier to improve noise
insulation properties of the enclosure.
170 Roof for outdoor water bassin
Tire strings are anchored to angle irons uhich are bolted on top of ~he concrete water bassin ualls
(ref.dwg#9).This type of roof replaces concrete or wood roofs commonly used to provide shelter against
sunligth to prevent bacteria growth and against free7e in t~.e winter time.The main advantages of the tires
are durability and low cost compared to the conventional roofs.lf leakage is objecti3naole for a particular
application a sealing membrane can be added.The present patent does not limit itself to roo4s on water
bassins and is applicable to any type of roo4 rhich could be constructed in the sarme fashion.
~rikes:
This new material is also used 40r dikes or small water dams.A ~-ater-proof membrane is wrappsd
180 around the tire strin~s which can bs prefsrrably sandfilled and is nailed or staprlsd to ths tires
(ref.dug#lO).A filler material ~sarth sand clav or any landfilling material) is put in place ~ga ns~ the
tirs dike which has bsen previously anchored to the soil uith wood posts or stesl beams ha~nered irto the
