摘要:
The invention provides a retaining device for assembling two panels together. The device has a support and first and second pairs of spaced-apart parallel walls extending along the support and projecting outwardly therefrom for providing first and second holding channels extending angularly to each other, each channel being adapted to receive an edge of one of the panels therein in a snugly relationship to allow assembling of the two panels. The invention also provides a formwork for forming a polygonal upright concrete structure using a plurality of retaining devices and a plurality of panels arranged with the retaining devices for providing a forming cavity between the panels adapted to receive concrete therein. There is also provided a packaging assembly for packaging goods using a plurality of retaining devices and a plurality of panels arranged with the retaining devices for providing a protecting cavity between the panels adapted to receive the goods therein.

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).

A form work system is disclosed. The form work system may include a pair of fiberglass hollow-core sheets forming an internal cavity that receives concrete to form a structure. The pair of fiberglass hollow-core sheets includes a top fiberglass sheet and a bottom fiberglass sheet and a plurality of fiberglass vertical supports coupled between the top fiberglass sheet and the bottom fiberglass sheet to form a plurality of internal channels. The form work system rebar fasteners extend through the pair of vertical supports, the pair of fiberglass hollow-core sheets, the internal cavity and the concrete to form the form work system.

A lightweight and flexible concrete forming tube for columns and pads is disclosed, wherein the tube has a very thin wall of high strength fabric and a longitudinal fabric tab running the length of the tube. The tab is sandwiched between two vertical support members made of lumber. The vertical support members and attached fabric tube are then accurately located and braced. As the interior of the tube is filled with concrete, the hydrostatic pressure causes the tube to form a cylindrical shape, thereby accurately aligning itself across from the vertical support members. The use of fabric prevents the problems associated with using cardboard forms, which weaken when exposed to moisture.

摘要:
A concrete form (10) comprises a single insert assembly or a plurality of insert assemblies (20) within an outer tube (12). Each insert assembly (20) comprises a pre-formed polymer liner sheet (30), a pre-formed polymer backing sheet (40), and a plurality of prefabricated cellular material pieces (22). Each cellular material piece (22) has a first surface configured to form a portion of the non-round cross-section desired for the column and an opposite second surface formed substantially as an angular section of a cylinder. An insert assembly (20) is constructed by affixing the liner sheet (30) to the first surfaces of a plurality of the cellular material pieces (22). The cellular material pieces (22) are arranged in a plurality of laterally adjacent rows extending lengthwise along the liner sheet (30) for a length approximately equal to the length of the outer tube (12). The backing sheet (40) is affixed to the second surfaces of the cellular material pieces (22). The liner sheet (30) and backing sheet (40) together substantially fully envelope the cellular material pieces (22).
