Definitions

  • the invention relates to assembly blocks for building construction with recesses for inserting insulating material for thermal insulation and to a method for producing such assembly blocks.
  • the invention is also concerned with the appropriate use of the blocks.
  • Hollow blocks with pockets are known (DE-PS 1 946 869; DE-OS 2 508 151 or DE-OS 2 553 123), into which comb-shaped insulating plates, e.g. in the form of rigid foam pieces to improve thermal insulation. It is unfavorable for the thermal insulation to regularly interrupt the insulating plate inserts on the stone crosspieces due to the construction (in the longitudinal direction between the individual plate parts), which creates so-called cold bridges. The insulation is also usually interrupted on the abutting surfaces of the stones. In addition, the introduction of the preformed rigid foam pieces in the known mounting blocks is associated with considerable effort.
  • Wall blocks are also known which contain two slot-like recesses filled with insulating material, which can penetrate the entire stone horizontally parallel to the direction of the wall and which extend over a considerable vertical distance from the top and bottom into the stone (BE-PS 710 667). In these blocks, too, an interruption in the thermal insulation on the abutting surfaces of the stones is practically unavoidable.
  • the production of the known wall blocks is associated with considerable effort, especially if stones of different lengths or designs are desired in accordance with the requirements for construction.
  • To produce assembly blocks that should have an exact stone height in the edge area it was previously customary to manufacture the stones on the vibrating machine in the horizontal position corresponding to their later laying, and the height deviations that were unavoidable due to the vibrating process by milling the bearing surfaces, e.g. balance with a machine according to DE-PS 1 427 712. Apart from the effort required for this, the horizontally lying stones take up a lot of space on the base of the vibrating machine.
  • the invention solves the problem of creating easily and quickly relocated mounting blocks with integrated thermal insulation, which enable almost uninterrupted thermal insulation and can be produced with less effort than before.
  • the assembly block described here has the advantage, among other things, that the insulating plates in all areas of the wall (both in the stone material itself and in the vertical and horizontal mortar joints) can achieve consistently high thermal insulation and there are no cold bridges. Thanks to the possibility of being able to move the insulating plates horizontally in the recesses, this advantage also applies to walls with non-standard, i.e. more or less any, longitudinal dimensions.
  • the movability of the insulation panels also allows them to be or door openings are preferred so that windproof heat insulation takes place. Small cavities that may arise contain standing air, which is known to provide similar thermal insulation to the insulating inserts themselves.
  • the horizontal, continuous arrangement of the insulating plates means that the assembly blocks can be produced both on vibrating machines with vertical production and on extrusion presses with horizontal production.
  • the assembly block described here is preferably to be manufactured standing on its abutting surface. Due to the conically tapering cross-sectional shape of a preferred embodiment of the stone, the removal of the shape used for production, which has correspondingly inclined inner surfaces, is facilitated by the freshly shaken stone, since the unavoidable frictional forces, especially with larger ones, on a sheet a plurality (for example, 12 or 16) of stone-forming shapes can be significantly reduced.
  • This "vertical production” in turn has the advantage that the tolerances of the stone height, i.e. a precise spacing of the plane-parallel bearing surfaces (provided only at the edge regions of the stone) can be maintained without the previously required complex milling process. Only these contact surfaces, which touch without mortar, determine the position of the stones during dry installation.
  • the mounting block shown in Figs. 1 and 2 has two horizontally in the longitudinal direction, i.e. parallel to a wall to be erected, the entire stone continuously penetrating recesses 1 or 2, of which the one recess 1 extends vertically downwards starting from the top of the stone at a given distance from the one side surface of the stone.
  • the other recess 2 has the same given distance from the other side surface and extends vertically upwards starting from the underside of the stone.
  • Insulation plates 4 such as e.g. rigid rigid foam panels used.
  • the special mutual arrangement of the cutouts 1 and 2 or of the insulating plates 4 also allows the insulating plates 4 of the two layers to be aligned vertically when the blocks are also mutually laid in two vertically successive layers, as can be seen in FIG. 6.
  • the respective panels touch each other on their end faces and thus interrupt a cold bridge on the entire, relatively large mortar joint.
  • the two recesses 1, 2 extend vertically beyond the center of the stone to such a depth that they overlap in the central region of the stone over a considerable vertical distance. This interrupts the horizontal "cold flow" in the central area of the stone or in any case forces it to take a larger route through the stone material, which is also insulating.
  • the stone material can consist of pumice, leca, brick material, etc.
  • the special mutual arrangement of the insulating plates 4 according to FIG. 2 and according to FIG. 6 also makes sense. With regard to the vapor pressure gradient which arises in every building due to the temperature differences and which practically always runs obliquely from the top downwards to the outside. With the described assembly block, the vapor diffusibility of the wall remains in everyone Get trap because the insulating plates 4 form a resistance, but the remaining insulating stone material has sufficient diffusion ability.
  • the cutouts 1, 2 taper conically from the top and bottom of the stone to the center of the stone, and at their inner end they are preferably dimensioned so narrow that the insulating plates 4 can be clamped there. If the insulating plates 4 are inserted into the recesses 1, 2 in the construction, which is facilitated by a width of the recesses at the outer end of which slightly exceeds the plate thickness, and the plates are then pressed lightly towards the center of the block, they are clamped by the conical taper.
  • the described shape of the recesses also initially facilitates any horizontal displacement of the insulating plates 4 in their recesses in accordance with the particular needs of the building.
  • insulating plates 3 located on the side surfaces of the recesses 1, 2 e.g. in the form of vertical bead-like webs.
  • the insulating plates are used so that they protrude laterally from their recess at one end and engage in an adjacent block when erecting a wall.
  • 1.2 insulating plates 4 with the same dimensions are used in the two recesses.
  • insulating plates with the length of several assembly blocks can also be used.
  • the cutouts 1, 2 are expediently approximately triangular in cross section at their inner end. This improves the static stability of the stone and also favors the flow of material when it is poured into the molds.
  • the resulting cavities are not filled by the generally rectangular insulating plates 4, but they contain standing air, which also achieves an insulating effect and the "cold flow" is further diverted or extended.
  • the triangular shape can also be modified up to an approximately semicircular cross section.
  • the assembly blocks shown in FIGS. 1 to 4 can be produced on normal production machines for hollow trestles, the horizontal recess 1 being produced by a mold core and the recess 2 by pulling a sword.
  • the core and the sword are slightly conical towards the center of the stone in accordance with the shape of the recesses described.
  • the beads 3 mentioned can also be formed.
  • the described arrangement of the recesses 1, 2 or the continuous insulating plates 4 also allows the use of stone production machines which, e.g. working in the brick industry in the strand process.
  • the assembly block can be produced from a perforated stone material on an extrusion press, as shown in FIG.
  • a mortar bed 6 can be pressed in and shaken during production with a complaint plate.
  • the webs 7 which remain here can first be produced to a height exceeding the desired stone height and, after the mounting block has hardened, machined plane-parallel with a special milling machine (e.g. according to DE-PS 1 427 712) and milled by a few millimeters.
  • the assembly blocks are preferably produced without milling in the manner explained in more detail below with reference to FIGS. 9-13.
  • the invention can also be applied to assembly blocks which are produced in the region 10 without extremely precise height tolerances of the webs 7 and the support surfaces. Stone height tolerances are then compensated by applying the appropriate thickness of bedding mortar, which, however, requires the use of a cord and spirit level for each layer laid. The special insulating effect by the plates 4 is essentially retained in this case too; only in the area of the bed joints could smaller mortar areas become visible due to the stone height deviations.
  • the longitudinal recess 11 In order to lighten the weight and as a grip hole, which facilitates the laying of the assembly block, there is a longitudinal recess 11 in the top or bottom of the stone.
  • the longitudinal recess 11 also serves to accommodate mortar that may have been filled in too much, i.e. of the mortar bed 6.
  • the mounting block at the four corners in the butt joints receives recesses 12 for receiving the butt joint mortar. The depth of these recesses 12 is such that superfluous bedding mortar can escape from the mortar bed 6 downwards.
  • FIG. 4 shows an assembly block which, in addition to the features already described, has a plurality of separating grooves 13.
  • the separating grooves facilitate sawing or hitting the block on the building if special stones are required, e.g. those with vertical slots 19 according to FIG. 7 or stones for wall connections according to FIGS. 5 and 6.
  • special stones e.g. those with vertical slots 19 according to FIG. 7 or stones for wall connections according to FIGS. 5 and 6.
  • a piece of insulating plate 14 which has been sawn out can be laterally reinserted, so that the thermal insulation is not interrupted.
  • the insulating plates 4 according to FIGS. 3 and 4 can be moved horizontally according to the needs of the building, as indicated by the arrow 15.
  • This is in contrast to known assembly blocks, which have crossbars in their recesses for holding the outer stone shell and thereby hold the insulating inserts, and to blocks whose insulating inserts consist of fillings which are not readily removable.
  • these can be pulled sideways, for example when erecting a wall with an uneven length, in such a way that larger distances arise between the individual blocks, as shown in FIG. 3 at 16.
  • both insulating plates 4 are pulled forward so that they engage in the next block and thus seal the butt joint with a high thermal insulation effect.
  • the assembly block is mainly used for erection in front of external walls and should usually be laid in rows in a whole layer of stone. Because of the required stone height precision, the first layer of stone is placed cleanly and horizontally in mortar on a ceiling or foundation. At the butt joints, the individual assembly blocks are put together dry (without mortar), the insulating plates 4 engaging in the next assembly block. Then the bedding mortar is brought into the prepared mortar bed 6 of the entire row of stones and pulled off with a board over the webs 7.
  • next stone layer is simply laid on top of one another in a row laying with respect to the previous layer, the surface areas 10 being placed on the webs 7. Due to the dead weight of the assembly blocks, they are sufficiently pressed into the mortar bed 6 with the elevation 18 remaining between the areas 10. Possibly. superfluous mortar is pressed into the longitudinal recess 11 or into the recesses 12 of the butt joints. An alignment of each stone layer with a cord and spirit level is not necessary when using the milled (or according to FIGS. 9 to 13 precisely manufactured) assembly blocks, and the mortar bed of the bed joints is isolated and sealed from the outside by the webs 7. When the assembly blocks are laid alternately, the bearing mortar joints, which are otherwise susceptible to a "cold flow", are interrupted and insulated by the mutual contact of the insulating plates 4.
  • the insulating plates 4 are inserted into the assembly blocks during manufacture. However, it is also possible to supply the insulating plates 4 loosely and to have them used on construction sites. A particularly interesting possibility with regard to optimal insulation is to use insulating plates 4 in double height and e.g. to be used continuously when laying on the building, the mounting blocks of the next row being placed over the insulating plates 4 above. Such insulating plates 4 then avoid any interruption of the insulation in the area, the mortar bed 6.
  • the assembly blocks can be quickly installed in rows by specialists as well as laypersons, and by simply filling the bed joints with mortar and then pulling them off with a board, there is minimal effort and a considerable saving in time and material costs. This could largely remedy the current shortage of skilled workers.
  • the assembly block described below largely corresponds to the one described above, that is to say it has plane-parallel lower and upper openings made to an exact stone height (arrow 25 in FIGS. 13 and 17) in the edge region of the stone bearing surfaces 20, 21 (FIGS. 1 and 13) and two recesses 1, 2 (FIG. 11) formed from the top and bottom of the stone for inserting insulating plates 4 (FIG. 14, etc.) for thermal insulation and 12), which in the longitudinal direction running parallel to the wall direction, ie parallel to the support surfaces and perpendicular to the abutting surfaces, normally penetrate the entire stone continuously.
  • the longitudinal surfaces which determine the width of the support surfaces 20, 21, the cutouts 1 and 2 and the strips which protrude on the underside of the block (in FIG. 11 above) become without laying further compensated by the bedding mortar.
  • the side surfaces 40 may possibly be less inclined or, if necessary, even run plane-parallel.
  • retaining strips 26 for the insulating plates 4 are integrally formed on the walls of the cutouts 1, 2 which are conically inclined towards one another and which run in the longitudinal direction with their edges facing the insulating plates parallel to one another and to the bearing surfaces 20, 21.
  • the widening of the recesses 1 and 2 corresponding to the cross-sectional taper facilitates the insertion of the insulating plates 4, while the non-conical strips 26, which increasingly project relative to the walls 1 ′ of the recesses, facilitate a longitudinal displacement of the insulating plates with reliable holding in the transverse direction.
  • the reverse is the case.
  • the outer surface remains closed and the cutouts 1, 2 in the inside of the stone end so shortly before this outer surface that the remaining bottom 33 is used for Wear plaster on the end of a wall or pillar required thickness of e.g. 1 to 2 cm.
  • These blocks usually serve as corner stones or end stones.
  • a form forming a plurality of blocks is used, in addition to the three types of stone for a wall dressing in the same form, a small number, e.g. with 16 or 20 blocks two slit stones (Fig. 19) are also produced.
  • the blocks in question are pressed in adjacent to their upper abutting surface, vertical knife-like steel cores 36, with which slots are formed which, if necessary, allow stone parts 37 to be cut off.
  • the slots are pressed in at a point such that the separable stone parts 37 are located on one side of one block or on the opposite side of the other block, so that a "right” and a "left” slot stone are available.
  • These slit stones are designed so that they can also be processed as a normal block without separation if no special blocks are required.
  • the shape used to manufacture the blocks can be at least partially smoothed on their surfaces by a coating.
  • chrome plating avoids Areas corresponding to the support surfaces 20, 21, especially when the shape is used for a long time. Deviations in the stone height from the nominal size. All surfaces of the mold that are at risk of wear are preferably chrome-plated or provided with another coating.
  • the chrome plating also significantly increases the lubricity of the mold when it is lifted from the stone blank, ie it is easier to remove from the mold.
  • FIGS. 15 and 14 show the bottom, first stone layer of the wall or its second stone layer.
  • a gap 30 penetrates the other block row over its entire cross section in the longitudinal direction of one row of blocks, abutting the abutting surface of the last block thereof, and a continuous insulating plate 31 is inserted into this gap.
  • the gap 30 is located between the last normal block 41 and a block 39 forming the outer corner of the same block row, which has a smaller, namely 1/3 the length of the other blocks.
  • the short block 39 is held at the corner by the bearing and butt joint mortar and bound in the transverse direction by the next stone layer.
  • the insulating plate 31 is cut somewhat smaller as a plaster base and mortared at 32 in the outer area.
  • a 1/3 stone is offset flush on the outside, creating a 5 cm wide cavity through the entire wall thickness in the form of the gap 30 in the manner explained above, which is filled with a 5 cm thick insulating plate 31.
  • a central dressing is of course also possible.
  • the block 39 shown in Figure 21 with 1/3 of the normal length can not only be used for the particularly thermally insulating corner bandage according to Figures 14 and 15, but it can also stand on its butt surface (i.e. in its production position) for the bottom or top layer of stone a wall for the purpose of height compensation with good thermal insulation.
