Abstract
The invention provides an improved formwork assembly for erecting a concrete or other similar material wall. The assembly includes a plurality of elements to form varying thicknesses and varying heights of wall with or without rigid insulation. Each element is interconnecable to its counterpart to form two parallel rows of formwork into which the concrete or other similar material is poured. The connecting elements have holes in their length to facilitate the flow of the concrete or other similar substance and for the placing of reinforcing rod for initial strength and stability. The assembly also provides for the construction of corners so that walls can be joined at a 90 degree angle on both sides of the parallel rows of elements as well as a means of replacing damaged wall elements after construction.
Description
Description Modular Formwork System For Concrete or Other Similar Material Comprising a Plurality of Interconnectable Formwork Components This invention provides an improved formwork assembly method for erecting a concrete or other similar material wall.
Background of the invention Concrete formwork assembly has long been used in construction of all types of buildings. This type of modular formwork first was invented in Norway as an octagonal form interconnected longitudinally and is widely used in Europe. The Canadian version is shown in the following Canadian patents:
Background of the invention Concrete formwork assembly has long been used in construction of all types of buildings. This type of modular formwork first was invented in Norway as an octagonal form interconnected longitudinally and is widely used in Europe. The Canadian version is shown in the following Canadian patents:
2,218,600 1999/08/31 Octaform Systems Inc.
2,215,939 1999/08/24 Octaform Systems Inc.
and though such formwork assembly systems have been mildly successful there has been a continuing need for improvement.
Summary of the Invention Considered broadly, formwork assembly systems are a plurality of elements with sliding connection methods along longitudinal edges so as to form parallel rows of wall elements. These formed cavities are then filled with concrete or other similar material with reinforcing bar interconnected inside the formwork. Other formwork assembly systems have had problems in erection with too many elements (Octaform Systems requires 4 extra elements per cylinder to strengthen the outer wall) required to complete the wall section and if any of the elements are missed the flat wall is pushed out by the concrete filling. Our system negates the need for these four elements by changing and strengthening the flat wall element and the connection method.
Further our system provides for a method of replacing damaged wall elements in some cases that have heretofore been unremovable and irreplaceable even after damage. Our connection method allows different siding finishes by using a "snap" connector system to easily change styles.
In the drawings, which form a part of this specification, Figure IW2-lOIR is an enlarged view of the connection detail of the flat wall elements and the connector.
Figures IW2-1008, IW2-1028 are full wall section details of the 4" and 6"
walls respectively.
Figure IW2-1038 is a full wall section detail including a rigid insulation element.
Figures IW2-113, IW2-1048, IW2-lOSR are views of the 4", 6" and 8" wall connectors respectively.
Figures IW2-108, IW2-107, IW2-1068 are full wall section details of the 4", 6"
and 8"
walls respectively showing inside and outside corner details.
Figure IW2-109 shows flat wall panel detail Figures IW2-112, IW2-111, IW2-110 are views of the 4", 6" and 8" walls inside corner elements respectively.
Figure IW2-114 shows outside corner element for all wall systems Figure IW2-115 shows "snap" connector detail.
Detailed Description of the Invention The particular advantages of the invention illustrated are ease and quickness of erection, strength, ease of change of style, the ability to add insulation factors and the ability to erect varying tlucknesscs of wall.
The elements are of extruded PVC or other similar material for ease of handling and shipping The longitudinal connecting elements have holes (figure IW2-113) spaced throughout their length to facilitate the flow of concrete or other similar material and the placement of reinforcing rod to strengthen the wall. Their connectors consist of two parts (figure 1W2-10182) 1. A sliding connector along the longitudinal length for a connection method to the flat wall elements 2. A "snap" connector for a connection method for a cap or other style of siding element.
The flat wall elements (figure IW2-109) is a universal flat wall element for use in all wall applications and can be of any color and is changeable after construction and pouring of the concrete or other similar material.
The inside and outside comer elements facilitate ease of transition in changing wall direction (figures IW2-108, IW2-107, IW2-1068) As best seen in figures IW2-10082, IW2-1028 and IW2-1038 the formwork assembly system connects along the longitudinal length of the elements to form a cavity that when filled with concrete or other similar material makes an impenetrable wall system impervious to water and weather.
