Abstract

A foundation for buildings temporarily erected on the ground comprises a row of plinths made up of spacer frames stacked on top of one another. These frames are made of identical plank sections whose ends are laid crosswise on each other and joined together by means of spikes, the hardened tips of which protrude from the timber in opposite directions. <IMAGE>

Description

20 25 b) UI 467 059 plan än de inbördes parallella undre plankorna 2l, 2a och sträcker sig vinkelrätt mot dessa senare. Ramens plankor är hopfästa medelst vertikalt riktade spikar 29, lämpligen 4 stycken vid varje hörn, vilkas härdade spetsar 3l skjuter ut växelvis uppåt och nedåt, så att de vid stapelns hoplägg- ning tränger in i angränsande ramar och därigenom säkrar sta- peln mot sidoförskjutning. Vid sammanläggning av stapeln orienteras ramarna växelvis åt olika håll, så att angränsan- de ramars plankor anligqor mot varandra endast vid stapolns hörn. B) UI 467 059 planes than the mutually parallel lower planks 21, 2a and extending perpendicular to these latter. The planks of the frame are fastened together by vertically directed nails 29, suitably 4 at each corner, the hardened tips 3l of which project alternately upwards and downwards, so that when the stack is assembled they penetrate into adjacent frames and thereby secure the stack against lateral displacement. When assembling the stack, the frames are oriented alternately in different directions, so that the planks of the adjacent frames abut each other only at the corners of the stack.

Grundplattorna 19 är kvadratiska och skjuter utanför sta- peln, d.v.s. deras horisontella mått är större än dis::nsra- marnas. De kan bestå av t.ex. fyra relativt tunna tätt lig- gande plankor 33 och två grövre tvärslåar 35 med samma inbör- des avstånd som i ramarna.The base plates 19 are square and project outside the pile, i.e. their horizontal dimensions are larger than those of the dis :: ns frames. They can consist of e.g. four relatively thin closely spaced planks 33 and two thicker crossbars 35 with the same mutual distance as in the frames.

Den översta ramen i stapeln orienteras företrädesvis så som fig. 9 visar, d.v.s. så att dess översta plankor blir Vinkelräta mot bärbalkarnas 13, 15 plankor, när dessa läggs på plats. Om höjdläget behöver justeras, inskjutes en eller flera mellanläggsplattor 37 under balkarna. Alternativt kan den översta distansramen vridas 90O, så att balkarna med eller utan mellanlägg kommer att vila mot de undre plankorna i den översta ramen och alltså helt eller delvis skjuter ned mellan dess övre plankor. Med enkla medel är det alltså möjligt att bygga upp ett stabilt och i höjdled noggrant justerbart mark- underlag.The top frame of the stack is preferably oriented as Fig. 9 shows, i.e. so that its uppermost planks become perpendicular to the planks of the supporting beams 13, 15, when these are laid in place. If the height position needs to be adjusted, one or more shims 37 are inserted under the beams. Alternatively, the upper spacer frame can be rotated 90 °, so that the beams with or without spacers will rest against the lower planks of the top frame and thus completely or partially slide down between its upper planks. With simple means, it is thus possible to build up a stable and in height accurately adjustable ground surface.

När i markunderlaget ingår flera i linje med varandra utlagda stödbalkar 13, 15, placeras en plint mitt under de' sammanstötande balkarnas ändytor och balkändarna förbindes medelst den i fig. 7 visade skarvsatsen, som består av två plåtbrickor 39, 41 och två mellan dem insatta bultar 43, 45, vilka vid hopmonteringen insättes genom tfärgående hål 47, 49, fig. 2 och 3,i balkändarna, och åtdrages så att plåtbrickorna uﬁf-d. anpressas mot deras motsatta sidor.When the ground base includes several support beams 13, 15 laid in line with each other, a plinth is placed in the middle under the end surfaces of the abutting beams and the beam ends are connected by means of the joint set shown in Fig. 7, which consists of two plate washers 39, 41 and two inserted between them. bolts 43, 45, which during assembly are inserted through through holes 47, 49, Figs. 2 and 3, in the beam ends, and tightened so that the plate washers u ﬁ f-d. pressed against their opposite sides.

Markunderlaget tillhandahålles som en i fabrik tillverkad standardiserad byggsats, varav man på platsen för den proviso- 10 l5 467 059 riska byggnaden tar ut erforderliga delar, beroende på mar- kens höjdförhållanden m.m., och manuellt lägger samman dessa samt efter avvägning justerar plintarnas höjd så att ett nog- grant horisontellt fundament för byggnaden erhålles. Efteråt skeende sjunkning av marken kan lätt kompenseras genom in- skjutande av extra mellanläggsplattor 37. Sedan byggnaden flyttats, kan underlagets delar lätt skiljas åt och oskadade användas på ett nytt ställe.The ground base is provided as a factory-manufactured standardized construction kit, of which the required parts are removed at the site of the temporary building, depending on the ground's height conditions, etc., and manually folded together and after balancing, the height of the plinths is adjusted so that a accurately horizontal foundation for the building is obtained. Subsequent subsidence of the ground can easily be compensated by inserting extra spacer tiles 37. After the building has been moved, the parts of the base can be easily separated and undamaged used in a new location.
