<p>#CMT# #/CMT# The method for the preparation of a building construction uses a hardenable material and an inflatable body. The construction is a cross arch. It involves four anchoring points (1) at the angle points of a four-sided basic surface reciprocally connected by means of tension wires (2) via the intermediary of a connecting plate (3). Centrally located between the anchoring points of the tension wires is an inflatable body (4). #CMT# : #/CMT# The anchoring points can be directly fixed to a floor surface, but can also be fixed to a heightened component, such as a column at a distance from the floor. Optionally, the volume of the inflated body can be further limited by positioning a casing which works in conjunction with the tension wires, for formation of side walls (5). #CMT#USE : #/CMT# For the preparation of a building construction i.e. a cross arch. #CMT#ADVANTAGE : #/CMT# The method is less labor-intensive than prior art and in a simple way a building construction of hardenable material is obtained. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The figure displays a possible preferred version of the method. 1 : anchoring points 2 : tension wires 3 : connecting plate 4 : inflatable body 5 : side walls #CMT#METALLURGY : #/CMT# The tension wires can be of steel. #CMT#POLYMERS : #/CMT# The tension wires may be of plastic. The inflatable material can be fiber-reinforced polyvinylchloride, polyurethane, polyethylene or polypropylene. Its inner layer can be a rubber-type material, such as butyl sheeting. On its exterior, is a water-repellent layer, such as polytetrafluoroethylene.</p> |
