Abstract:
The invention comprises a concrete form. The form comprises a first concrete forming panel having a first primary surface adapted for forming and contacting plastic concrete and a second primary surface opposite the first primary surface; a layer of insulating material contacting and substantially covering the second primary surface of the first concrete forming panel; and an insulating blanket adjacent the first concrete forming panel. A method of using the concrete form is also disclosed.
Abstract:
Various implementations described herein are directed to a formwork system. In one implementation, the formwork system includes aluminum extrusions and aluminum castings. The aluminum castings and the aluminum extrusions can be assembled by being pressed and riveted together.

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:
A structurally supportive backer panel formed to fit within the recesses of a form liner to support the form liner when casting textured surfaces into concrete. The backer panel has a series of protrusions which fit within the recesses of the form liner in order to prevent the concrete pressure from deflecting and buckling the form liner. When the wet concrete is poured into a form fitted with the backer panel and form liner, the concrete fills the form and contacts the form liner, wherein the backer panel ensures that the shape of the form liner is not affected by the pressure and weight of the concrete.
Abstract:
A modular panelized form wall include a first wall panel and a second wall panel; and a support panel having vertical steel rails which frame the vertical sides of the support panel. The support panel is arranged between the first and second wall panels. The first wall panel, the second wall panel and the support panel are connected together to form a portion of the modular panelized form wall. Wide head brackets can be connected to a top of the support panel for an overhead self-lifting grid system to be attached to the modular panelized form wall. Wide landing brackets can be connected to a bottom of the support panel to transmit the loads from the support panel to the underlying support. Shear pins can be inserted through the vertical steel rails at various locations in the support panel and through corresponding holes in the first and second wall panels, the holes to receive the shear pins to distribute the vertical loads away from the support panel to the first and second wall panels.
Abstract:
The invention relates to a wall formwork (1) for concrete structures, comprising a basic body (12), an outer face configured as a formwork facing (19), and anchor holes (5) for the detachable connection to other wall formworks. It is proposed that the anchor holes (5) be disposed with a substantially uniform grid spacing (4) relative to each other, and to dimension the wall formwork (1) in such a way that the spacing (4) of the anchor holes (5) to the outer vertical (7) and/or horizontal (6) boundary of the wall formwork (1) corresponds to no more than half of the grid spacing (4), preferably substantially half of the grid spacing (4).
Abstract:
A recyclable formwork can suitably detect temperature of concrete cast contacting with the formwork in a field without spoiling the other functions of the formwork. The recyclable formwork is provided with: a main unit (1) including a plurality of ribs (3) and (4); a case (7) being housed between the ribs (3) and (4), the case (7) being fixed on a non-contact surface (1a); and a circuit housed in the case (7). A through-hole (16) is opened at a position corresponding to where the case (7) is fixed, the through-hole (16) penetrating the main unit (1) from the non-contact surface (1a) to a contact surface (2). A sensor-housing case (17) is provided with a lower portion of the case (7), the sensor-housing case (17) being inserted into the through-hole (16), a bottom face of the sensor-housing case (17) facing concrete. And, a concrete temperature-detecting sensor (19) for detecting surface temperature of the concrete is housed in the sensor-housing case (17).
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 present invention provides a half panel having on its back ribs defining symmetrically complimentary closed wall open faced cells and ribs having spaces there between. The half panel may be placed in back to back relationship and rotated through a required degree of rotation so that the open faced closed wall cells and ribs having spaces there between interlock so the open faced closed wall cells have at least one diagonal cross member. This provides a rigid panel suitable for a number of applications including forms for pouring concrete.
