DE3326621C2 - Method for producing the topsoil of a cavity floor and measuring device for carrying out this method - Google Patents

Abstract

In order to be able to control the adherence to a minimum thickness of the upper floor of a cavity floor, auxiliary devices with a foot adapted to the indentations of the shuttering sheet, to which a measuring stick is attached, are distributed across the indentations corresponding to the supporting feet of the upper floor.

Description

A marking 22 is attached to the dipstick 20, by which when the screed compound is later applied to the shuttering film 10, compliance the minimum thickness specified in advance is guaranteed will.

Claims (14)

1 2 would be based on a related method and claims: to propose a suitable measuring device for its implementation. 1. Process for the production of the topsoil with regard to the process, the solution is Nes cavity floor, which by means of support feet on the 5 task in that distributed over the formwork sheet a sub-floor rests, with the topsoil with the individual measuring devices, which are attached to the one-book support feet by pouring in a foot that is initially adapted to the flow and a vertically oriented one condition processable and later solidify- scale exist, inserted into the indentations the screed mass on one of the supporting feet, after which the flowable screed mass is at least equivalent Shuttering film 10 having indentations is formed on the shuttering film at least in such a thickness is marked by the fact that its level goes up to that of the individual e t that measuring rods distributed over the formwork foil (10) determine the minimum thickness Measuring devices (16) which reach from one to the lowing marking. The inventive Indentations adapted foot (18) and a ver measuring device consists of a prefabricated foot vertically directed dipstick (20) exist in the indentations 15 and one protruding from the top, indentations (14) are used, after which the kai-directed dipstick. flowable screed mass at least in such a way that over the entire extent of the screed floor Thickness is applied to the formwork film that dens ensures compliance with a minimum thickness its level is up to that of the individual measuring rods, the screed mass is up to the level of the awning, the marking, which defines the minimum thickness, is applied to those measuring devices which are after tion (22). the distribution of the measuring devices over the 2. The measuring device for the implementation of the process foil occupies the highest position Ren according to claim 1, characterized in that the minimum thickness is then determined according to the distance it consists of a marking of the dated and fitted in front of the dipstick, which is adapted to the indentations manufactured foot (18) and one from the top 25 feet of this measuring device. Provided, outstanding, vertically directed measuring stick (20) that the measuring devices used in individual cases if the feet have the same height, the marking is included 3. Measuring device according to claim 2, characterized in that all measuring devices are at the same height above the foot, that the foot (18) from the same Ben. Screed as the top floor consists of 30 The use of the measuring device according to the invention 4. The direction of measurement according to one of the two devices has the advantage that when walking in one direction Claims 2 u "d 3, characterized in that the feet are marked in the indentations of the shuttering film distinguishes that the measuring stick (20) from the same this under the weight of the feet, which expediently Screed as the top floor consists of the same screed compound as the top floor, 5. The measuring device according to one of the preceding 35 must be pressed firmly against the sub-floor. at the claims 2 to 4, characterized in that formwork foils with a greater formality it is formed in one piece, it can be in the case of larger unevenness of the subfloor it can happen that the film closes in individual areas. next before the onset of the measuring devices 40 in the indentations of the shuttering foil, not on the Sub-floor rests The invention relates first of all to a method Production of the top of a cavity floor, measuring device according to the invention from the same which rests on the subfloor by means of supporting feet, with screed like the upper floor and is more advantageous The top floor with the support feet is formed in one piece with the foot by pouring it in. Through this They can initially be processed in the flow state and later difficulties arise due to different solidifying screed mass on one of the supporting material properties between the poured Shea measuring device with corresponding indentations and the screed of the top floor liner is trained. Such a procedure is in void. the DE-OS 31 03 632 described. In this case, problems can arise that protrude from the screed mass, with the frequently encountered un- measuring rods are removed after completion of the top floor regularities or unevenness on the top, for example by pinching
of the subfloor. Since the generally in the drawing is an embodiment of the NEN made of plastic formwork film later inventive measuring device and its use under the weight of the screed applied in the method according to the invention is pressed against the subfloor and is illustrated table. With 10 a plastic is thereby adapts to the irregularities mentioned, referred to film, which lies on the sub-floor 12 and If the screed is aligned at the right level, the screed is retained as lost formwork for a still-to-be-made formwork ner top in the individual areas a sub-top panel is used. In an indentation 14 of the different thickness. This brings about that particularly in the case of an eo shuttering film 10 that is designated as a whole by 16 more marked irregularities of the sub-floor measuring device used which has a foot 18, side with it the risk that for static reasons with which a vertical dipstick 20 was required in one piece Minimum thickness for the screed, generally the is. The height of the foot 18 is expediently below 20-25 mm, in the areas where the film is higher than that of the indentation 14. As in the drawing only comes to rest, is fallen short of. 65 a section from the formwork film is shown A suggestion that compliance with such a min- only one of the measuring devices was shown by dedestdicke can ensure in a simple manner, lies, NEN several arranged distributed over the entire film as far as can be seen, not before. The invention is on the rise.
