Abstract:
This invention relates to a set of pieces or parts making up a system of metallic adjustable formwork for concrete structures in civil Works which functions is to allow the assembly, junction and adjustment of the formwork system in the most efficient way with the use of a system of adjustable formwork which looks for to use the shorter quantity of metallic panels as accessory during the project execution. The way as the each element has characteristics of specially defined shape, size and function to get a rigid structure, which allow to build a mold over which the concrete is poured maintaining their characteristics and perform such functions rapidly, efficiently and securely.
Abstract:
The invention relates to an anchoring system for a wall formwork and to a method for an assembly of the anchoring system: the two wall formworks (1, 2, 3, 40) are set up opposite from each other, an anchoring rod (4) with a graduation (21) is pushed through anchoring rod bores of the two wall formworks (1, 2, 3, 40) in such a way that the end of the anchoring rod (4) that has not been pushed through has the graduation (21), the pushed-through end of the anchoring rod (4) is connected to a locking device (41) present on the rear side of the one formwork (40), the end of the anchoring rod (4) that has not been pushed through is connected to the locking device (5, 6, 7, 8, 13, 14, 15) provided here in such a manner that this connection is aligned with the selected graduation, the locking device aligned with the graduation is connected to the adjacent wall formwork (1, 2, 3).
Abstract:
The present invention is directed to a flexible concrete form system having both flexible and rigid parts that are easily assembled and disassembled using a multi-contact point connection system. The concrete form system can be extended or stacked in a wide variety of configurations to accommodate almost any desired concrete shape.
Abstract:
A formwork panel comprising at least one covering sheet comprising a concrete engaging front face, the at least one covering sheet being supported on a frame secured on a rear side thereof to support and reinforce the sheet, said frame comprising first and second elongate, spaced apart and substantially parallel side rails and first and second elongate, spaced apart and substantially parallel end rails, said first and second side rails and first and second end rails defining, between them, a peripheral boundary of the frame, respective ends of said first and second side rails being joined to respective ends of said first and second ends rails by respect corner members, each corner member defining a corner region of the frame.
Abstract:
The invention comprises a concrete form. The concrete form comprises a first panel having a first primary surface for contacting plastic concrete and a second primary surface opposite the first surface; and a second panel having a first primary surface and a second primary surface opposite the first surface, the second panel being attached to the first panel so that the first primary surface of the second panel is adjacent the second primary surface of the first panel. The concrete form also comprises a layer of radiant heat reflective material and a layer of insulating material disposed between and covering the second primary surface of the first panel and first primary surface of the second panel. A method of using the concrete form is also disclosed.
Abstract:
There is disclosed to provide a recyclable formwork that can add the new function without spoiling the other functions of the recyclable formwork. The recyclable formwork includes: a main unit including a contact surface contacting with cast concrete, a non-contact surface being parallel and opposite to the contact surface, and a plurality of ribs outstanding from the non-contact surface to a side opposite to the non-contact surface and reinforcing the main unit; a case being housed between the plurality of ribs and being fixed on a side of the non-contact surface; and a circuit being stored in the case. A first highest point of the case at the side of the non-contact surface is not higher than a second highest point of upper ends of the plurality of the ribs.
Abstract:
Disclosed herein is a form that includes a wall having a first surface and a second, opposing, material-receiving surface. The form further includes a slot extending substantially across the wall and between the first surface and the second surface. Furthermore, the form includes a first waler attached to the first side of the wall directly above or directly below the slot, the first waler including a plurality of openings spaced across the length of the first waler. The openings are each configured to receive an inserted wedge bolt.
Abstract:
Lightweight, reinforced, non-biodegradable, tubular plastic footing form members and assemblies which may contain stake-engaging bores and/or are nailable to each other and/or to supporting stakes. The form members are water-repellant to resist absorbing and bonding to wet concrete compositions so that they can be removed and cleaned for repeated reuse. Alternatively they can be left in place, since they are inexpensive and non-biodegradable, and can support a porous drain conduit adjacent the formed footing.
Abstract:
A wall form panel for use in constructing a poured concrete wall form is preferably extruded from aluminum and a plurality of sections which are joined together form the wall form panel. The outer side most sections of the wall form panel advantageously include integrally formed and extruded side flanges to provide enhanced load-bearing capability and reduce the likelihood of failure. The extruded panel sections are coupled together along longitudinally extending joint members and reinforced beams and struts are welded to the back face of the wall panel sections for added strength and rigidity. Advantageously, the wall form panel sections can be formed in a plurality of widths and joined together in various combinations to conveniently provide a variety of widths of wall form panels. The side flanges of the wall form panels includes holes for attaching pins and other associated hardware. Advantageously, a reinforced bushing is seated within the flange to provide increased strength and avoid material failure in this location.
