DE2904236A1 - Fixing industrial plastic tiles onto concrete base - using reinforced plastic cement in joints to allow for expansion and to protect the edges of the tiles - Google Patents

Abstract

Edges of expansion gaps an industrial floors are protected by a reinforced plastic cement. Floor is laid on a concrete base with expansion gaps at intervals. Over this is laid a covering e.g. in plastic. To allow for expansion but at the same time to protect the edges, the gap is filled with a plastic or synthetic resin with a steel filler for reinforcement. A polythene insert is fitted into the gap, and the joint is then made using a special tool which projects down into the slot. For use on industrial floors. Gives improved life to the floor by reducing wear and damage due to passage of trucks etc with metal wheels.

Description

1. Verbatim copy of the description and sponsorship

Proverbs Process for the production of stable and straight joint edges Floors for industrial buildings usually consist of a concrete substructure and a screed placed on top. To avoid the formation of cracks, these floors are provided with separating joints at certain intervals, which run through both the screed and the substructure.

However, the edges in the screed crumble under traffic - E.g. iron wheels from trolleys rolling over them - quickly.

At first glance, this looks ugly. Because of that, it becomes wider and wider The resulting separating joints also create a significant traffic hazard, e.g. loads fall off the truck.

To avoid this, the edges have already been reinforced with metal rails, which are fastened with screws or bolts in the concrete substructure, Over time however, the metal rails loosen.

This again leads to new inconveniences.

The invention aims to address this disadvantage in joint edges of floors for industrial buildings with a substructure made of concrete and overlaid with a screed layer and in certain Spaced joints to compensate for expansion, thereby avoiding that in the screed and joints arranged in the concrete substructure with a plastic or synthetic resin mortar or another suitable material with high edge strength intimately and inseparably are connected or reinforced. The extremely solid compared to the normal screed Plastic can withstand the traffic load at the edges, but can at the same time, in contrast to metal rails, due to its close bond with the concrete, do not shake loose.

According to a further proposal of the invention are in the for reinforcement serving plastic mortar in the same distributed deposits of steel fibers and electrocorundum grain incorporated.

This contributes to a further increase in edge strength. Through this horizontally and vertically impacting loads are elastically absorbed.

uie production of the joint edges takes place in that for their production a plane or slide-like tool is provided, which in the longitudinal direction with an exchangeable bar to fix the joint width and on both sides of the same The sword-like is provided with exchangeable and clampable height fixtures-the former Steg creates the joints in the plastic mortar when the tool is pulled through, while the laterally adjustable height fixing bars the width of the plastic mortar area determine.

It is also provided that for the longitudinal guidance of the slide-like Tool are arranged in the longitudinal direction on one or both sides guide bars, which will be removed after completion.

In this way, the rectilinear guidance of the tool is guaranteed. To save on expensive plastic mortar, there are PE pre-fill profiles in the corner of the concrete substructure inserted.

Otherwise the plastic mortar would down to the reason of the familiar building run through.

The drawings show an embodiment of the invention.

It denotes: FIG. 1: a cross section through a finished floor with reinforced joint edges Figure 2: a cross-section through the floor at the moment the production with the tool according to the invention.

Figure 3: a side view of the tool.

FIG. 4: a plan view of the tool in the direction of the arrow A of Figure 3.

FIG. 5: a plan view of the tool in the direction of the arrow B of Figure 3.

FIG. 6: a section through the tool along the dashed line D-D and viewing direction in the direction of arrow C in FIG. 3.

In Figure 1, 1 is the concrete substructure with the joint 2 and the screed 3 with the joint 4, in which the plastic mortar 5 is used for reinforcement.

The PE pre-fill profile is still located in the plastic mortar 5 8. With 9 ioage of steel fibers and corundum grains are distributed in the plastic mortar designated.

10 is a plane or sled-like one used to produce the joints 6 Tool, which can be made of metal or plastic, with the side-shiftable Height fixing web 1 and the sword-like web 12.

13 are guide bars for guiding the tool 10 in a straight line.

14 steep wing screws are used to clamp the laterally movable ones Height fixing webs 11, while the sword-like web 12 with the wing screw 15 is attached.

The carriage 10 carries the handle 16.

The height fixing webs 11 are in slots 17 in the tool @@ are located, arranged to be laterally displaceable.

18 is the thrust direction of the tool 10.

How it works: First, the concrete substructure 1 with the joint 2 in manufactured in a known manner, in which the PE pre-fill profile 8 is then inserted, then the guide bars 13 are fixed on the concrete substructure 1.

Then the Lir hem between the height fixing webs 11 and the pre-fill profile 8 filled with plastic mortar 5. The tool 10 is then attached to the guide bar 13 and the tool 10 is moved longitudinally in the thrust direction 18.

The sword-like web 12 is pressed into the soft PE pre-fill profile 8 in. Displaced by this longitudinal shift; n - rounded1 sword-like Web 12 the synthetic fabric mortar 5 and thus creates the joint 6.

After the joint 6 has been produced, the tool 10 is made from the plastic mortar 5 lifted out and the guide bar 12 removed.

After the plastic mortar 5 has hardened, the screed 3 is applied.

The invention relates not only to the exemplary embodiment described but also includes all other manufacturing methods that work according to the same principle of reinforced bow rims.
