Description
i 144182in 144182
Opfindelsen angår et vægelement for bærende eller ikke-bærende vægge i én- eller fleretages bygninger, hvilket vægelement er opbygget af kalksandsten, der er sammenføjet til en retvinklet begrænset enhed og er for-'-' 5 bundet med hinanden ved hjælp af en mørtel.The invention relates to a wall element for load-bearing or non-load-bearing walls in single- or multi-storey buildings, which wall element is constructed of limestone sand which is joined to a right angled limited unit and is connected to one another by means of a mortar.
Fra DE-OS nr.2.359.428 kendes der en vægelement-konstruktion af denne art, bestående af kalksandsten, der er beliggende med indbyrdes ens fuger over hinanden, og som før en hydrotermisk hærdningsproces er sammenføjet 10 ved hjælp af en i leje- og stødfugerne anbragt, ikke nærmere defineret mørtel. Den sammenføjede enhed hærdes derefter i en hærdekedel, hvorved såvel kalksandstenene som mørtelen bibringes den endelige styrke.From DE-OS No. 2,359,428 there is known a wall element construction of this kind, consisting of limestone sand, located with mutually identical joints over one another, and which before a hydrothermal curing process is joined together by means of a bed and a bed. the joints placed, not specified mortar. The joined unit is then cured in a curing boiler, providing the final strength of both the lime sandstones and the mortar.
Disse kendte vægelementer har den væsentlige u-15 lempe, at de kun er i besiddelse af en ringe styrke, at de har tendens til at slå sig under hærdningsprocessen/ og at de - ikke mindst på grund af håndteringen af de endnu ikke hærdede kalksandsten (under montagen) og på grund af den specielt afpassede hærdningsproces - med-20 fører betydelige byggeomkostninger, hvortil kommer, at de har tendens til målunøjagtigheder på grund af hærdningsprocessen i tilslutning til kalksandstenenes sammenføjning til vægelementet.These known wall elements have the major drawback that they possess only a slight strength, that they tend to settle during the curing process / and that they - not least because of the handling of the not yet cured limestone sand ( during assembly) and due to the specially adapted curing process - carries significant construction costs, in addition to tending to inaccuracies due to the curing process in connection with the lime sandstone joining to the wall element.
Opfindelsen har til formål at eliminere foran-25 nævnte mangler ved de kendte vægelementer.The invention aims to eliminate the aforementioned shortcomings of the known wall elements.
Med udgangspunkt i den indledningsvis omhandlede konstruktion tilsigter opfindelsen nærmere bestemt at skabe et vægelement, der kan fremstilles på en enkel, hurtig og billig måde, og som dels er i besiddelse af en 30 høj totalstyrke, der muliggør transport ved hjælp af en griber, som kun angriber den øverste stenrække, og dels tillader fremstilling med en høj målnøjagtighed, som ligger inden for snævre tolerancegrænser.More specifically, on the basis of the preamble of the invention, the invention aims to create a wall element which can be manufactured in a simple, fast and inexpensive manner and which, in part, has a high total strength, which enables transport by means of a gripper which only attacks the top row of rocks, and partly allows manufacturing with a high target accuracy that is within narrow tolerance limits.
Til opnåelse heraf er vægelementet ifølge op-35 findelsen ejendommeligt ved, at kalksandstenene har en specifik vandsugnings- 2 evne på ikke mere end 12 g/ (dm x min) og en fra de forud fastlagte stenudgangsmål begrænset afvigelse på 14-4182 2 + 1,0 mm og er muret i forbandt, at kalksandstenene i området af stød- og lejefugerne er beliggende med en fugetykkelse mellem sig på ca. 3 mm og er forbundet med hinanden ved hjælp af en 5 tyndtflydende mørtel, der medfører en adhæsionstrækstyr-ke mellem kalksandstenene på mindst 0,7 MN/m , at den tyndtflydende mørtel er tilberedt af en tør mørtel i form af en blanding, der består af ca. 74 vægtprocent sand 0-1 mm som tilslag, ca. 25 vægtprocent 10 portlandcement som bindemiddel og ca. 1 procent af et organisk stof som tilsætning, der forøger vandtilbageholdelsesevnen, og at der til den tørre mørtel - regnet ud fra tørblandingens vægt - er tilsat ca. 7,5 vægtprocent af en 15 anden tilsætning, der forøger adhæsionstrækstyrken, og ca. 11,5 vægtprocent vand.In order to achieve this, the wall element according to the invention is peculiar in that the limestone sandstones have a specific water suction capacity of not more than 12 g / (dm x min) and a deviation from the predetermined stone output dimensions of 14-4182 2 + 1. , 0 mm and is walled in connection that the limestone sandstones in the area of the impact and bearing joints are located with a joint thickness between them of approx. 3 mm and connected to each other by means of a thin-flowing mortar, which gives an adhesion tensile strength between the limestone sandstones of at least 0.7 MN / m, that the thin-flowing mortar is prepared by a dry mortar in the form of a mixture consisting of of approx. 74% by weight of sand 0-1 mm as aggregate, approx. 25% by weight 10 Portland cement as a binder and approx. 1 percent of an organic substance as an additive that enhances water retention and that to the dry mortar - based on the weight of the dry mixture - is added approx. 7.5% by weight of a second addition which increases the adhesion tensile strength and approx. 11.5% by weight of water.
Hed opfindelsens foranstaltninger er der skabt et vægelement, som opfylder de stillede krav.In accordance with the inventive measures, a wall element has been created which meets the requirements set.
Med udformningen ifølge opfindelsen opnås der 20 således et vægelement, der kan fremstilles manuelt eller maskinelt med en usædvanlig høj målnøjagtighed, og som har plane flader, der kun er afbrudt uvæsentligt af de smalle stød- og lejefuger, og som ikke kræver nogen afpudsning, hvortil kommer, at vægelementet ved høj form-25 stabilitet er i besiddelse af en sådan totalstyrke, at det uden videre kan gribes i området af den øverste stenrække respektive håndteres ved hjælp af en enkel gribertang. Den særlige tyndtflydende mørtel danner desuden en transportarmering, der fordelagtigt virker som en art 30 klemgitter, og der er samtidig skabt sikkerhed for, at der - til trods for de smalle stød- og lejefuger - ikke optræder termiske problemer i den tyndtflydende mørtel under afbindingen, hvorved vægelementernes ringe vandbelastning tillader anvendelse af disse umiddelbart efter 35 deres fremstilling.Thus, with the design according to the invention, a wall element is obtained which can be manufactured manually or mechanically with an exceptionally high target accuracy, and which has planar surfaces which are interrupted only insignificantly by the narrow bumps and bearings and which do not require any trimming, for which For example, the wall element at high form stability has such a total strength that it can easily be gripped in the region of the top row of stones and handled with a simple gripper tong, respectively. In addition, the special thin-flowing mortar forms a transport reinforcement, which advantageously acts as a type 30 clamping grid, while at the same time ensuring that, despite the narrow bumps and bearing joints, thermal problems do not occur in the thin-flowing mortar during the bonding, whereby the low water load of the wall elements permits their use immediately after their manufacture.
Ifølge opfindelsen kan der som den første tilsætning, der forbedrer vandtilbageholdelsesevnen, være anvendt f.eks. tylose eller celluloseæter, og der kan U4182 3 som den anden tilsætning, der forøger adhæsionstrækstyrken, være anvendt en blanding, som indeholder en latex fra saranrækken.According to the invention, as the first addition which improves the water retention capability, e.g. tylose or cellulose ethers, and as the second addition which increases the adhesion tensile strength, a mixture containing a latex from the saran row may be used.
