Abstract

The production relates to the finishing of large concrete areas with large glazings and polishers. The production are new in that the generation further relates to a locking mechanism in the form of a splintlås that optimizes the application, stability, flexibility, safety and durability of components, by glitteskiven, polishing disc and the fixing ring is locked relative to each other.

Title

Grinding and polishing system for mounting on a trowel.

Frembringelsens scope

The production is directed to a grinding and polishing system for a trowel. The overall area of the creation is in the construction industry. Subordinate it in after treatment of cast concrete and cement areas, which are typically large industrial and warehouse halls and other large molded areas. Common to these is that there are areas containing a large number of square meters.

Background art

The prior art is an abrasive system for mounting on a trowel, wherein the system comprises a glitteskive for mounting on a glittemaskines wings substrate held fixed to the metal disc, a polishing disc fixed to the substrate latch, a flexible fixing ring mounted along the periphery of the polishing disc and a plurality of sieve i be / po lerskiver mounted on the polishing disc.

Grinding and polishing concrete is well known and not new. The technique used is dependent upon the size of the area as well as the type of equipment. For very small areas used everything from hand machines. The need for larger and more efficient machines grows with the area and in relation to the material to be ground and polished. Basic sledge used the same machines functionally and tools and techniques for both small and large areas.

There are three general types of personal operated grinders. For small areas are typically hand with one of a small rotary sander. For medium land used a floor sander and smaller floats, and for large areas used grinding and floats. Common to all types is that they have a rotating shaft on which the grinding or polishing disc is locked. Locking a sanding / polishing pad at the small machines, so it does not fall off when grinding and polishing, typically secured by means of an attachment bolt or hex nut. This method is used because there typically is a need for transfer of high power through high speed from the machine for grinding / polishing disc, and thus to the topic, and there arises thus a need for the best possible clamping of the disc to the machine. It is the forces from the machine's revolutions, as viewed in a relationship with a combination of man, machine and the material results in inducing a risk that there may be a damage to a three objects being performed by a grinding and / or polishing.

During polishing, the same tool is used, with a flange påspændes / backing pad in the same manner described above, but it did a velcro. In the sanding pad is mounted a polishing pad on which on one side is glued to a disc having a non-woven wire, which ensures the maintenance of the polishing disc to the adapter. This nut and Velcro locking system also provides a flexible operating mode to quickly switch to a new or different grinding or polishing wheel.

Using the big machines, gulvsliberne and glittemaskinerne vary this technique know that there are differences in how the grinding and polishing discs mounted and lock style engines.

It is in this difference lies the problem, and is described under "technical problem". There is also talk that the grinding and polishing function are combined into a single coherent system, which can both grind and polish at the same time.

For small areas, the standard grinding and polishing discs. A - The standardized grinding wheels are very rigid in their structures and with the grinding wheels, which are embedded in a material. The material contains a graduated amount and size of the grinding discs. This modulation is used in relation to the hardness and gravity of the area, sanding, and in relation to the desired end result. B - Polishing discs also have a graduation in relation to their gravity in relation to how smooth and shiny a surface, you want the end result to be. Common to the standard products is that they have a smaller size and thereby surface that is adapted to the need to grind and polish small areas.

The diameter of these products thus adapted to the area as they can grind and polish on, designed for small needs and tasks and can not be used to solve large areas. They are therefore not functionally practical and thus not economically viable in large areas.

The method used, is also well known. The method is based on a starting point, which is the gravity of the surface area which is to be cut and polished. It compares that with the desired end result. From there it then selects appropriate a grinding and polishing wheels, which gradually cut and polish towards the desired end result - ranging from coarse to fine grinding and polishing of the area.

The technical problem

How can glitteskiven, polishing disc and the fixing ring is locked relative to one another?

The new technique

What is new is that the grinding and polishing system comprises a splintlås (2e) for the passage through glitteskiven (2a), the polishing disk (2c) and the flexible fixing ring (2d) for fixing the entire system relative to each other.

With the new technique will ensure a secure locking of the grinding and polishing system in a practical and functional manner, so that the same safety and well-known function is achieved at the same time can be made as well as grinding polishing in one process.

The tekmske effect / new technology

As described in the above, there are challenges associated with increasing grinding and polishing area. This is due to the fact that a specific need in order to apply a well-known, safe, functional and cost-effective solution to post-process large concrete and cement areas.

In order to better maintain, center and stabilize and secure grinding and polishing function during operation is compared to previously known technique applied; 1. A unique splintlås (2e) of stainless steel, for the passage through glitteskiven (2a), the polishing disk (2c) and the flexible fixing ring (2d), for fixation of these (2a, 2c, and 2d) with respect to each other, which ensures all grinding and polishing system from harm by a flexible but strong, locking of the grinding and polishing system for glitteskiven (2a).

Splint lock (2e) provides a much more efficient locking feature that allows the effect of increased durability, flexibility, usability, security and strength for polishing and grinding system.

There must be applied several splinter lock depending on glitteskivens size for optimum stability.

With the new technique achieves merits of a combination of well-known techniques without compromising, but enhance safety, durability and stability when cutting, polishing and large concrete areas in one process.
