Abstract

The invention relates to a method of construction of concrete beams or walls using a formwork module comprising an elongate rectilinear front face, a peripheral border wall extending from the front face, two spaced pairs of bolt sockets extending through the rectilinear front face, and a plurality of opposed slots in the peripheral border wall.

Claims

1. A method of construction for concrete beams or walls comprising the steps of:

(a) setting rows of a plurality of boxing modules in an end to end relationship to create a formwork,

(b) fastening abutting ends of the modules, and

(c) spacing the formwork by a plurality of spacers which span between the module panels and are fixed by bolts, or push-in ties,

(d) bracing and straightening the formwork as required,

(e) setting reinforcing between the formwork as required, and

(f) pouring concrete into the formwork.

2. A method as claimed in claim 1 wherein the spacers may be hollow tubular members or push-in ties.

3. A method as claimed in claim 1 wherein the boxing modules are joined utilising slots in side and end walls of the modules.

4. A method as claimed in claim 1 wherein the quick release clamping devices are used to join the side and end walls of the modules.

5. A method as claimed in claim 1 wherein the quick release clamping device is a wedge.

6. A method as claimed in claim 1 wherein the quick release clamping device is a strap which joins respective ends of the modules and sets the spacings between the modules.

7. A method as claimed in claim 1 wherein the individual modules comprise a rectilinear front face, a peripheral border wall extending from the front face, two spaced pairs of bolt sockets in major surfaces of the modules and a plurality of opposed slots in the peripheral border walls of the modules.

8. A method as claimed in claim 1 wherein some of the panels of the formwork are joined and others are not.

9. A method as claimed in claim 1 wherein the inner walls of the modules or panels are used to create designs or patterns in a formed wall.

10. A method as claimed in claim 1 wherein the formwork is reinforced by elongate straps or beams.

11. A method as claimed in claim 10 wherein elements of the straps or beams are adjustable to increase the strength of same.

12. A method as claimed in claim 1 wherein the modules are joined together in a staggered formation.

13. A method of creating a formwork for a horizontal column from a plurality of modules, supporting the formwork from a surface below and integrating the columns with a floor slab.

14. A formwork comprising a plurality of joined boxing modules in an end to end relationship wherein each boxing modules has front and rear faces and a continuous peripheral flange about the rear face said flanges having openings therein so that the boxing modules can be united via the flanges using quick release clamping devices.

15. A formwork as claimed in claim 14 wherein the joined boxing modules are made parallel by a plurality of spacers spanning between the modules.

16. A formwork as claimed in claim 14 wherein the quick release clamping devices are wedges.

17. A formwork as claimed in claim 14 wherein the quick release clamping devices are straps.

18. A formwork as claimed in claim 14 wherein the formwork is braced and stiffened by elongate braces.

19. A formwork as claimed in claim 18 wherein the braces are vertical, horizontal or angular.

20. A formwork as claimed in claim 14 wherein the boxing modules are rota-moulded.

21. A formwork as claimed in claim 20 wherein two modules are formed together with rota-moulding and then separated on removal from a mould.

22. A formwork as claimed in claim 20 wherein the modules are provided with integral or external stiffening members.

23. A formwork as claimed in claim 14 including vertical and horizontal reinforcing bars which extend from the ends and top and bottom surfaces of the formwork.
