Description

Uppfinnare: D J Stern Denna uppfinning avser armerade betongTor. Inventor: D J Stern This invention relates to reinforced concrete.

Anvandningen av stalhylsor inbaddade i ett betongrors gods är kand och Okar i hiig grad vattentatheten av raret. Ett andam.fil med foreliggande uppfinning ar att uppna vattentathet betydligt lattare och billigare in med stalhylsor och vidare att fOrminska naekdelarna med stalhylsan, sasom benagenhet for korrosion i narvara av vissa vfitskor. The use of steel sleeves embedded in the goods of a concrete gutter is kand and Okar to a large extent the water resistance of the raret. An object of the present invention is to achieve water tightness much more easily and more cheaply with steel sleeves and further to reduce the naked parts with the steel sleeve, as well as to be prone to corrosion in the presence of certain white shoes.

Det ar ett ytterligare andamal med uppfinningen att astadkomma lamplig armoring for roret annorledes an genom .staihylsor. It is a further object of the invention to provide suitable armor for the pipe differently than through steel sleeves.

Enligt foreliggande uppfinning bestar ett satt att forma ett betongfOremal av dot ifragavarande slaget i att en betongkarna omgives med en betong- eller cementhylsa, sa att det lamna_s ett mellanrarn mellan dam, och att i mellanrummet forlagges en lamell air kon.sthartsmassa bunden vid kfirnan och hylsan, varvid lamellen ar armerad fOr att meddela inneboende styrka at foremalet. According to the present invention, a method of forming a concrete form of the dot in question consists in that a concrete core is surrounded by a concrete or cement sleeve, so that an intermediate pipe is left between the dam, and in the space a lamellar air resin mass bonded to the concrete and the sleeve, the lamella being reinforced to impart inherent strength to the form.

Konsthartsmassan ar aTmerad med glasfiber eller armeringsstanger som ftirlaggas i mellanrummet mellan karnan och hylsan, innan hartset halles i detsamma. The synthetic resin mass is reinforced with fiberglass or reinforcing bars which are laid in the space between the core and the sleeve, before the resin is poured into it.

Uppfinningen innefattar aven ett f8remal av det ifragavarande slaget, nar det framstallts enligt det ovan angivna .sattet. The invention also comprises an article of the type in question, when prepared according to the above method.

Uppfinningen fortydligas pa bifogade ritning. Fig. 1, 2 och 3 aro bilder av de olika stegen av tiliverkningen av ett ror. The invention is elucidated in the accompanying drawing. Figs. 1, 2 and 3 are views of the various steps of the manufacture of a rudder.

I fig. 1 ser man ett vanligt cylindriskt betongror 10, t. ex. ett som tillverkats centrifugait. Fig. 1 shows an ordinary cylindrical concrete pipe 10, e.g. one manufactured centrifugally.

I fig. 2 ar rOret 10 insatt i ett liknande ror 12 av starre diameter, sa. att 'let fir lamnat kvar ett ringformigt mellanrum 14. Koren fast-lianas vertikalt, och den undre anden av mellanrummet 14 Or tillsluten medelst en propp 16. Harts, t. ex. ett polyester- eller ,ett epoxiharts, halles sedan i mellanrnmmet i ett flytande tillstand for att fylla detsamma samt bringas eller tillates att stelna och att hardna, da det haftar mycket sakert fast vid rOren 12 °eh 14 fOr att bilda en ringformig flerskiktkropp. In Fig. 2, the tube 10 is inserted into a similar tube 12 of rigid diameter, said. that the ring is left an annular gap 14. The cores are fixed vertically, and the lower spirit of the gap 14 is closed by means of a stopper 16. Resin, e.g. a polyester or, an epoxy resin, is then held in the intermediate space in a liquid state to fill it and brought or allowed to solidify and harden, as it adheres very securely to the tube 12 ° or 14 to form an annular multilayer body.

Innan hartset halles i mellanrummet 14, fOrlagges arrneringsstanger, sasom utvisas. vid 18, inuti mellanrummet. Before the resin is poured into the gap 14, decorative rods are placed, as shown. at 18, inside the space.

Flerskiktkroppen kan sedan omlindas med forspand trad spiralformigt for att forspanna konstruktionen, sdsom synes. i fig. 3, varvid traden 20 sedan tackes med ett lager 22 air cementmaterial. The multilayer body can then be wrapped with prestressed wire helically to prestress the structure, as it appears. in Fig. 3, the wire 20 then being thanked with a layer 22 of air cement material.

Roret enligt uppfirmingen kannetecknas air ,stor hallfasthet och motstandskTaft mot bristning. Lamellen Or intim ber8ring med betongen, med vilken den ar verkligt sammanhangande, ar korrosionsbestandig samt bildar ett utmarkt vattentatningsnaedel. The rudder according to the invention can be characterized by air, high hall strength and resistance to rupture. The lamella or intimate contact with the concrete, with which it is truly cohesive, is corrosion resistant and forms an excellent waterproofing needle.

Claims

Patent claim:

Concrete grooves, which carried an inner, hollow concrete core (10) and a riled denim-connected outer cement sleeve (12), characterized in that between the core and the cement sleeve lies a reinforcing sleeve consisting of synthetic resin, in which reinforcement is embedded, and that the reinforcing sleeve is intimately bonded to the heton core and the cement sleeve.

2. Concrete grout according to claim 1, characterized in that the reinforcement embedded in the reinforcing sleeve consisting of synthetic resin mass consists of fiberglass.

3. Betongror efter patentanspraket 1, Unneteekn, at darav, att den i den av konstharts- Dupl. at 47 f: 3/25; 80 a: 51; 80 b: 1/07; 80 b: 13/01; 80 b: 13/02 2 mass of existing reinforcement sleeve embedded reinforcement consists of reinforcement bars.

4. Set to disassemble a concrete pipe according to claim 3, in which an inner, hollow concrete core and an outer, hollow cement sleeve are set up so that an annular space is formed between the core and the sleeve and the space is filled with a material in liquid or plastic condition which then becomes solidified, characterized in that a plurality of reinforcing rods are arranged in the space at a circumferential distance from each other around the core, so that the rods are at a radial distance from both the core and the sleeve, and that synthetic resin mass. in • liquid or plastic condition is kept in the intermediate space.
