MODULAR SCAFFOLD

Abstract

A modular scaffold, which includes parts to be joined to each other, which parts are at least standards, ledgers, working platforms and the necessary railings, and also ladders. The parts of the modular scaffold are fabricated mainly from plastic and/or fiber composite.

Claims

1. A modular scaffold, comprising: parts to be joined to each other, said parts being at least standards, ledgers, working platforms, railings, and ladders, wherein the parts are fabricated mainly from plastic and/or fiber composite.

2. The modular scaffold according to claim 1, wherein the fiber of the fiber composite is one or more of the following: wolfram, steel, glass fiber, carbon fiber, aramid fiber, other polymer fibers, boron fiber, graphite fiber, ceramic fibers (whiskers) and resin.

3. The modular scaffold according to claim 2, wherein the fibers of the fiber composite are mixed into the plastic material.

4. The modular scaffold according to claim 1, wherein at least some of the parts of the modular scaffold are fabricated by 3D printing.

5. The modular scaffold according to claim 2, wherein at least some of the parts of the modular scaffold are fabricated by 3D printing.

6. The modular scaffold according to claim 3, wherein at least some of the parts of the modular scaffold are fabricated by 3D printing.

Description

[0012] In the following, the invention will be described in more detail by the aid of some preferred embodiments with reference to the attached drawing, which presents an assembled modular scaffold.

[0013] The structure of a scaffold is per se known in the art and it comprises standards 1, to which are fastened ledgers/guardrails 4. Adjustable jacks 2 functioning as the lowest part of the scaffold are placed against the ground or against some other base, and base collars 3 are affixed to the jacks. The transoms/endrails are marked with the reference number 5 and the diagonal braces with the reference number 6. A working platform 7 is installed resting on the ledgers 4 and transoms 5. Ladders 8 are installed between the working platforms 7, which ladders enable climbing from one working platform to another. A scaffold can be further provided with toe boards 9.

[0014] The modular scaffold is fixed to the wall at certain intervals with ties 10. The figure also presents a bracket 11 and a platform clamp 12.

[0015] The structure of the modular scaffold according to the invention can thus be, per se, known in the art. The invention relates to the material of the scaffold, which is plastic or fiber composite. One or more of the following, for example, can be used as the fiber material of the fiber composite. wolfram, steel, glass fiber, carbon fiber, aramid fiber (Kevlar), other polymer fibers, boron fiber, graphite fiber, ceramic fibers (whiskers) and resin. The fiber composite according to the invention is obtained by mixing one/some of the aforementioned fibers into the plastic material.

[0016] The parts of the scaffold can be fabricated at the factory or they can be fabricated by 3D printing e.g. at the installation site of the scaffolding, in which case transportation of the parts to the installation site is completely omitted.

[0017] It is obvious to the person skilled in the art that the invention is not limited to the embodiments presented above, but that it can be varied within the scope of the claims presented below. Parts fabricated from plastic or fiber composite must, of course, meet all the strength properties required of scaffolding components.

[0018] At least most of the parts of a modular scaffold are fabricated from plastic and/or fiber composite. It is possible that some parts are also fabricated from conventional materials.

[0019] The modular scaffold presented in the figure is only one example of a scaffold meant by the invention. It can, of course, be of another shape and wider/narrower or higher/lower. What is essential is the modular structure, i.e. that it is assembled from parts at the construction site and it can be disassembled after use and transferred to a new location. A scaffold will comprise at least standards 1, ledgers 4, working platforms 7, railings 4, 5 and ladders 8.

[0020] The characteristic features possibly presented in the description in conjunction with other characteristic features can also, if necessary, be used separately to each other.
