Abstract:
A method for forming integrally insulated concrete sandwich walls or wall components is disclosed. The walls are fabricated by casting the walls vertically and pumping the concrete from the bottom of the form or from sides near the base. Walls fabricated thus can be used in commercial, industrial, residential, and agricultural buildings. These walls can be cast on-site or in a manufacturing plant.
Abstract:
Selon ce procédé : - on réalise au moins une première paroi (1), - on applique contre celle-ci au moins un organe intercalaire (20), comprenant un corps (30) en un matériau rigide entouré par une enveloppe périphérique souple (40), - on réalise la seconde paroi (2) et - on extrait l'organe intercalaire, en le soulevant par des moyens de préhension (44), prévus sur l'enveloppe, de façon à réaliser cet intervalle. L'opération de levage est simplifiée, puisque les moyens de préhension sont facilement accessibles pour l'engin de levage. De plus ce dernier n'a pas à être déplacé au voisinage immédiat des parois en béton. Enfin, il n'est pas nécessaire de déchirer au préalable l'enveloppe.
Abstract:
A through-insulation connector assembly for use in the construction of insulated concrete sandwich wall. The connector assembly includes a spool-shaped connector body (10) comprised of two, interconnecting pieces (12, 14) and a tie (50) that engages the connector body (10). The two pieces (12, 14) of the connector body (10) are installed at the place of manufacture in a sheet of foam insulation board (48) that will be used as the insulation layer (46) in the construction of an insulated concrete sandwich wall.
Abstract:
The present invention concerns a shuttering (100) for the formation of a wall or similar, comprising a first wall formwork device (10) of an insulating material and a second wall formwork device (20), which are formed to be arranged in parallel so that a space (x) is formed between them intended to be filled with flowing concrete. A number of form ties (30) are arranged to connect the first and second wall formwork devices (10,20). The first wall formwork device (10) comprises a number of building or plastic foam blocks (11), and the second wall formwork device (20) comprises a number of sheathings (21). Each form tie (30) is provided with a first end having a fastening element (40) formed for connection with the first wall formwork device (20), and in its second end provided with a clamp tie device (50) for locking to the second wall formwork device upon temporary mounting and retention/clamping of said second wall formwork device (20) during the concreting, and releasing/unlocking after casting for allowing the wall formwork device (20) to be removed, form stripping. The invention also concerns a procedure for forming, for instance, a wall as well as a support for a said shuttering.
Abstract:
A composite concrete shear wall for heat insulation comprises a wall (1) and a link beam (2). The wall (1) is composed of a prefabricated concrete wall for heat insulation (11) and a cast-in-place concrete wall. The prefabricated concrete wall (11) is a concrete panel (5), one surface of which is covered with heat insulation layer (4), and steel members (14) are embedded in the prefabricated concrete wall (11). One end of the steel members is embedded in concrete panels, and the other is projected from the heat insulation layer. The steel members are connected and located along the prefabricated concrete wall to form a framework of steel reinforcement. The prefabricated concrete wall (11) and the cast-in-place concrete wall (12) are cast and folded to be an integral.
Abstract:
By using a thermal insulation foam/film laminate wherein each major planar surface of a foam panel has a facer film bonded thereto that meets certain performance criteria rather than a foam panel by itself, composite walls that have a foam panel sandwiched between concrete layers can be made with fewer steps.
Abstract:
The present invention relates to a cast-in-place wall construction method comprising the steps of: determining the wall line; forming kicker along the determined wall line; providing at least one of heat protection material or sound protection material or water protection material inside the formwork; installing the formwork along the wall line such that there is a gap between the two panels of the formwork or a gap between one panel of the formwork and a rigid body located on the opposite side of said panel; filling the binder into the gap of the formwork; leaving said binder to harden and to cure within the formwork; and removing the formwork. According to the invention, the filling of binder into the gap of the formwork is carried out by positioning an end of at least one binder filling tube above the slurry surface level at which the binder is to be filled, with at least one binder filling tube being moved vertically or horizontally or with at least one binder filling tube being moved both vertically and horizontally in a relative manner.

Abstract:
L'invention concerne un procédé pour la réalisation d'un mur avec deux parois en béton entre lesquelles est emprisonné au moins un panneau isolant (4), les deux parois étant réalisées de façon simultanée par coulage de béton entre le panneau isolant (4) et deux banches interne (6) et externe (7). Le procédé consiste par la mise en place; sur chaque panneau isolant (4) avant leur positionnement, de systèmes de positionnement (13) comportant chacun au moins un crochet orientable angulairement, d'un ferraillage de structure interne (9) du côté de la face interne de la banche interne (6), de chaque panneau isolant (4) avec passage à travers du ferraillage de structure interne (7), des systèmes de positionnement (13), pour chaque dispositif d'assemblage (14), avant le positionnement de la banche externe (7), d'une entretoise tubulaire traversant le panneau isolant (4) et traversée par une tige de serrage (41) s'étendant à l'extérieur des banches pour recevoir à chaque extrémité un organe de serrage (42).
