Abstract

The adaptor comprises a sleeve, one end of which receives a threaded reinforcing rod and the other end of which receives a threaded plug. When the first stage of a concrete structure has been cast and the shuttering removed, the plug is exposed inside its surrounding cover. - Upon removal of the plug, another reinforcing rod can be screwed into the sleeve, allowing successive stages to be cast. The arrangement improves the sealing and resistance to shear stresses between two successive stages of a cast concrete structure.(0/3)

  DEMANDE DE DEPOT DE BREVET DE PERFECTIONNEMENT -

ADAPTATEUR DE BOITE D'ANCRAGE POUR BARRES A BETON

  
A) ENONCE du domaine technique.

  
Mise en oeuvre de barres à béton de gros diamètres, devant être laissées en attente pour accrocher une phase ultérieure d'un ouvrage en béton armé.

  
B) DESCRIPTION de l'état actuel de la technique.

  
Différents systèmes de boîtes d'attente pour petits diamètres (8 à 12 mm) sont bien connus.

  
 <EMI ID=1.1> 

  
sont également connues, les manchons d'accouplement à visser ou à presser se fixant directement sur les coffrages.

  
Après décoffrage, les barres d'attente sont soit dépliées, soit vissées dans les manchons.

  
C) INCONVENIENTS de l'état actuel.

  
Seules les barres de petits diamètres peuvent être traitées au moyen de barres d'attente.

  
Les barres de gros diamètres doivent encore se visser

  
 <EMI ID=2.1> 

  
Aucune préfabrication n'est possible. Le coût de la

  
main d'oeuvre est élevé et l'exactitude du positionnement des manchons est aléatoire.

D) DESCRIPTION DE L'INVENTION.

  
Les barres d'ancrage (4) sont fixées dans des manchons (3)

  
de n'importe quelle origine. L'adaptateur (5) muni de deux ergots et vissé dans le manchon (3) peut aisément, par une rotation de 180[deg.], se bloquer dans la boîte en queue d'aronde (1).

  
La boîte, appelée "COUPLER BOX", possède un filet embouti dans lequel l'adaptateur se visse ou se clipse. 

  
E) AVANTAGES qu'apporte l'invention.

  
Une boite prémontée de manchons et de barres d'ancrage améliore grandement l'exactitude du travail et augmente considérablement la rapidité d'exécution.

  
- Les manchons encastrés 1/2 dans le béton première phase et 1/2 dans le béton deuxième phase, transforment radicalement les caractéristiques de l'ancrage au cisaillement.
- La boite perdue dans le béton, créant un assemblage tenon-mortaise, assure une reprise nette et en augmente fortement l'adhérence et l'étanchéité.



  REQUEST FOR DEPOSIT OF DEVELOPMENT PATENT -

ANCHORAGE BOX ADAPTER FOR CONCRETE BARS

  
A) STATEMENT of the technical field.

  
Implementation of concrete bars of large diameters, which must be left waiting to hang a later phase of a reinforced concrete structure.

  
B) DESCRIPTION of the current state of the art.

  
Different systems of waiting boxes for small diameters (8 to 12 mm) are well known.

  
 <EMI ID = 1.1>

  
are also known, the coupling sleeves to be screwed or pressed attaching directly to the formwork.

  
After formwork removal, the waiting bars are either unfolded or screwed into the sleeves.

  
C) DISADVANTAGES of the current state.

  
Only bars with small diameters can be processed using waiting bars.

  
Large diameter bars must still be screwed

  
 <EMI ID = 2.1>

  
No prefabrication is possible. The cost of

  
labor is high and the accuracy of the positioning of the sleeves is random.

D) DESCRIPTION OF THE INVENTION.

  
The anchor bars (4) are fixed in sleeves (3)

  
of any origin. The adapter (5) provided with two lugs and screwed into the sleeve (3) can easily, by a rotation of 180 [deg.], Lock in the dovetail box (1).

  
The box, called "COUPLER BOX", has a stamped thread in which the adapter is screwed or clipped.

  
E) ADVANTAGES brought by the invention.

  
A pre-assembled box of sleeves and anchor bars greatly improves the accuracy of the work and considerably increases the speed of execution.

  
- The sleeves embedded 1/2 in the first phase concrete and 1/2 in the second phase concrete, radically transform the characteristics of the shear anchor.
- The box lost in concrete, creating a tenon-mortise joint, ensures a clean recovery and greatly increases its adhesion and tightness.
