Modular building scaffold based on pipes filled with water

Abstract

 The present invention consists in a modular building scaffold based on transparent pipes filled with water. It means to have a structure very easy to transport and manage which becomes a heavy and stable structured when every element is mounted on and filled with water. All the scaffold can be imagined like a unique long pipeline so that it is very simple to fill it with water. The Three main elements of the modular frame are the ledgers (1), which are the sole element partially assembled forming a square pipeline, the screw couplers (3,4) and the standards (2). Tubes are made of transparent material to ensure every one can control water level in real time.

Description

Application field

[0001] The present invention concerns building scaffolds. A scaffold is a temporary frame used to support people and material in the construction or repair of buildings and other large structures, on a scaffold workers sit or stand when performing their tasks. It is usually a modular system of metal pipes (usually called tubes in Britain), although it can be made out of other materials, they are usually made of aluminium or steel. The main element of a scaffold are: tubes, couplers, boards, stairs and guard rails.

[0002] Tubes are divided into up-rights or vertical tubes (also called standards) which are the vertical tubes that transfer the entire mass of the structure to the ground; ledgers, which are horizontal tubes which connect between the standards. Couplers are the fittings which connect tubes. Boards are the base on which workers stand. Stairs allow to reach an higher floor of the scaffold and finally guard rails ensure safety for people working on the platform.

[0003] The main problem with scaffolds is that they must be very stable and safe structures and must be mounted on and dismantled very easily and quickly. Therefore every single element of the scaffold should be easy to transport. By now many kinds of scaffolds have been invented trying to satisfy all these needs.

Detailed description

[0006] The present invention consists in a modular building scaffold based on transparent pipes filled with waster. Once every element is assembled, the basic module is a sort of big cube. The main part are: a square ledger 1, which is the only element partially assembled, it has eight primary holes 7 in its four vertexes, four at the top and four at the bottom. In this way every ledger can act as superior ledger, middle ledger and bottom ledger of the cube frame. The superior ledger has four screw caps 8 on the top holes and four vertical screw couplers in the bottom holes, The middle ledger (which is between two cubes) has eight vertical screw couplers and finally the bottom ledger has four caps in the bottom holes and four vertical screw couplers on the top holes. The standards 2 are simple single pipes which are connected to the ledgers by vertical screw couplers. Vertical screw coupler 3, has a screw thread 9 to connect by a safe way ledger and standard, and also has a watertihgt gasket 10. Also the cap has a screw thread and a watertihgt gasket. To connect two cubes horizontally the ledger has four secondary holes 11 which can have a horizontal screw cap 4 or a caps if the ledger is connected or not connected to another ledger. The board 5 and the guard rails 6 doesn't strictly belong to the invention but are necessary requisites of every scaffold, the way by which they are fixed in the structure is not important to describe the present invention. The stairs too are not strictly part on the invention and aren't shown in the drawings.

[0007] Once assembled, regardless of the number of vertical or horizontal cubes, all the scaffold is a unique continuous pipe, easy to fill with water. The transparent pipes ensure a continuous control of water level in real time. It could be useful to use colored water to easier control water level.

[0008] Single elements are very light and easy to transport, as the matter of fact is the water which give stability to the scaffold once it is filled with.
