Problems solved by technology

Furthermore, the resulting formwork lacks structural rigidity, and when the formwork is poured into concrete it suffers from a "banana effect", causing the walls of the formwork elements to bulge outward
This makes it difficult to secure wall finishes or cladding

Embodiment Construction

[0024] Referring to Figure 1, a set of generally concave elongate formwork elements 1 is provided. The elements are preferably made of a material such as polyvinyl chloride like the other components described herein. The elements have a surface 50 which may be three-sided or they may have more sides, be round or any other suitable shape, as long as the elements are substantially open so that the edges are not closed to each other. In this specification and in the claims, such a shape is referred to as "concave" for simplicity. The adoption of this shape gives the formwork a cylindrical appearance. The concavity also allows easy access to the inner surface 2 of the element 1 for placing or adhering various types of insulation (insulation) or linings inside the element before erecting the formwork or while making the elements 1 within the surface. Foam insulation as indicated at 3 may be used, or composite insulation or a thinner lining may be bonded to the inner surface of t...

Abstract

A modular assembly for creating formwork for casting vertical concrete structures is characterized by elongated, generally concave elements which are disposed in edge to edge relationship in two facing rows, and which are simultaneously retained in edge to edge relationship and in facing relationship by connecting members. The connecting members have spaced ribs allowing the flow of concrete across the plane of the connecting member.

Description

technical field [0001] The present invention relates to formwork assemblies and methods of assembly for pouring concrete to form vertical structures. [0002] The invention takes the form of elongated modular elements (members) adapted to be connected to each other along their long sides to form formwork for creating poured concrete to form walls or other vertical structures. Background technique [0003] It is known in the prior art to provide modular formwork elements which can be stacked end-to-end with a set of horizontal rows stacked one above the other to produce a formwork wall. Examples of such elements are disclosed in US Patent 2,172,052 to Robbins and US Patent 3,788,020 to Gregori. [0004] It is also known to provide modular formwork elements forming a set of vertical substantially closed forms which can be nested side by side with each other to produce a series of adjoining concrete columns. US Patent No. 5,216,863 to Nessa et al. discloses such elements havi...
