Benefits of technology

[0008] According to a preferred embodiment of the present invention, there is provided a tie assembly for a wall form unit. The tie assembly connects a first panel and a second panel which define a space to contain a portable, curable construction material, such as concrete, for forming a wall section. The tie assembly, first and second panels, and the cured construction material combine to form the final wall structure. A spacer member maintains the first and second panels in a predetermined relation. The spacer member has spaced apart, opposing edges, and each edge is provided with connecting means. A first and a second connecting member are each provided with a support for respective attachment to the first and second panels, and a coupling projecting from the support. The coupling defines a channel for sliding engagement with the connecting means. An abutment means permits the coupling and the connecting means to cooperate to detachably retain the connecting means.

Problems solved by technology

Furthermore, the removal of the form requires a significant amount of labour.
However, providing interconnections between form units which are effective, but which can quickly be engaged, is problematic.
Another difficulty in such systems is the lack of space efficiency in the transportation of pre-built form units to a construction site.
However, the connecting members described therein are expensive to manufacture since they are formed with a solid connecting channel.

Embodiment Construction

[0029] With reference to FIG. 1, a single form unit 20a is illustrated. In the construction of a structural component, for example a wall, several such form units 20a are utilized. Wall form units 20a are placed adjacent to, and in lateral alignment with, other form units to make a complete form structure, as illustrated in FIG. 10.

[0030] A single form unit 20a has a pair of spaced, generally 10 planar and transversely aligned panel members 22a and 24a. In one embodiment, panel members 22a and 24a are made from a lightweight, temperature insulating material such as polystyrene or an extruded form. The panels may however, be made of materials other than those which are particularly adapted to provide for temperature insulation, but which will retain the liquid material.

[0031] In FIG. 1, form unit 20a is shown with a single tie member 26a in detail. However, to provide greater stability for a form unit, a pair of tie members 26a and 28a may be employed.

[0032] As shown in FIGS. 2 an...

Abstract

A form system comprises several form units (100), each having a pair of panels (108) positioned in spaced relation to each other. A plurality of tie members (104) connects the panels, the tie member comprising a spacer member (112) disposed transversely between the panels. Each tie member further comprises a pair unit connecting members (116), one positioned on each of an outside surface of a panel. The spacer members are each connected to a first unit and a second unit connecting member through the first opening in the panels. The first and second unit connecting members have first and second connections respectively, to permit the first and second unit connecting members of a first form unit to be connected with corresponding first and second connecting members or a second form unit.

Description

FIELD OF THE INVENTION [0001] This invention relates to tie assemblies and wall form units and systems used to construct structural components such as walls. More particularly, the present invention relates to such tie assemblies, wall form units and form systems for walls formed of a pourable, curable construction material where the form system remains in situ. BACKGROUND OF THE INVENTION [0002] Construction components, such as walls and columns, are often made form castable materials such as concrete. As is well known, to make a specifically shaped component from such materials, a form is built or erected which functions as a mould for the castable material. In the past, forms were typically made form inexpensive materials such as wood. To make the component, the form is erected to create a cavity capable of holding the castable material (eg. concrete) in a liquid form. The concrete is then poured or otherwise fed into the cavity created by the form and then allowed to set. Once t...
