Definitions

  • the invention relates to a method for insulation or for subsequent insulation, in particular of building walls, and an insert element for carrying out the method:
  • one- or two-layer wall insulation is used in the construction industry to prevent soil moisture from being absorbed.
  • the single-layer wall insulation is made by z. B. tar paperboard is placed dry on the wall surface to be insulated and the extension points are connected with hot bitumen, pitch, or with bituminous or pitch protection coating.
  • the insulation. panels on the wall surface and glued to each other with hot bitumen are insulated against moisture in a similar way.
  • the need for a subsequent waterproofing is not only apparent in old buildings, e.g. B. in those with an art object character, but also in buildings with brick walls, mud walls, even in buildings with concrete walls in an ever wider circle.
  • the subsequent waterproofing of buildings with brick walls is carried out by breaking out about four layers of brick in a length of 1 m and, after the insulating cardboard has been inserted, the dismantled material - as far as possible - is dismantled.
  • the strong dynamic loads associated with the expansion represent a not insignificant use for the building, which has largely perished anyway. ' This often damages the building structure.
  • the specialist is forced to carry out this work, which requires special expertise, under accident-prone conditions, since he has to work by hand in the removed cavities of the masonry, the binding agent of such masonry generally being quite fragile, and even often the brick itself being less strong having.
  • an electrical wall seal is also used, in the course of which the wall construction containing the absorbed moisture is electrically dried out with enormous energy consumption and technical effort.
  • wall sealing methods with a chemical character are known, in which materials such. B. in the trade under the names "VANDEX”, or “PENETRAT” or “WALLCO - or” SILIKOFOB-ANHYDRO "known chemicals can be injected into the wall, whereby the wall construction itself is impregnated and the walls are taught waterproof or water-repellent properties In this way, the capillary moisture absorption of the wall is abolished.
  • AT-B-228 987 relates to a method for the subsequent insulation of walls against rising damp as well as a device for carrying it out.
  • An insulating bag filled with tar, concrete, cement mortar or the like is placed in a joint made by a masonry saw in the masonry; however, this insulating bag has a pre-support function.
  • a method for draining damp walls is known from AT-B-335 689.
  • a masonry made of fired bricks which are arranged in droves and separated from each other by layers of mortar, corrugated insulating panels are then hammered into the masonry by hand or with the aid of a suitable tool and pressed in tightly. This is a very tedious process, which may damage the masonry.
  • the aim of the invention was to eliminate the deficiencies mentioned above.
  • the object of the invention is to develop a solution for waterproofing which can be implemented in a shorter time, in a simpler way, even with semi-skilled workers.
  • a further requirement is that damage to the building structure during the subsequent insulation can be avoided, the quality is better and the service life is longer than in the previously known solutions.
  • the task is solved by the further development of a known method used for wall insulation, in the course of which, during the performance of the wall, an insulating layer is placed on the surface to be insulated.
  • this method was further developed in that the insulating layer is made of load-bearing, prefabricated lattice-like insert elements, as well as of an insulating, optionally binding material that is introduced into the openings of the installed insert elements.
  • This method was further developed in accordance with the invention in that lattice-like insert elements, which were prefabricated from plastic, were advantageously used as load-bearing elements in the incision gaps, the insulating layer being designed by injecting a substance having insulation and binding properties into the part of the incision gaps provided with the insert element.
  • a post-curing substance advantageously a synthetic mortar with a polyester resin binder, is expediently used as the insulating and binding agent.
  • the insert element according to the invention is designed as a lattice-like element, prefabricated from advantageously thermoplastic, which has a support grate and adjoining, forming a uniform grid and load-bearing units, the load-bearing units protruding above the upper or lower level of the support grate.
  • the load-bearing units can be balls which are rotatably mounted in the carrier grate.
  • the ball can be used as a monolithic unit with the support grid, e.g. B. be made in plastic by injection molding.
  • the elements are provided on their end faces with projections and with the recesses receiving them, which in the installed position serve for releasable connection to the adjacent insert elements.
  • the insert element has a circumferential frame, the height of which falls below the height of the load-bearing element, is advantageously approximately 0.9 times that, but at the same time exceeds the height of the support grate, the frame being designed with at least one injection hole .
  • FIG. 1 shows the insulation of a load-bearing wall 1 made of brick over a top edge 2 of the floor, which was produced using the method according to the invention in the case of the wall not having a satisfactory water seal:
  • the wall 1 is made in the height to be insulated in a manner known per se (e.g. by a chainsaw), in the perfect horizontal cross-section, in a length between 60 and 110 cm - in the present case 100 cm - Cut through, whereby an incision gap 3 is formed with a uniform height H.
  • the height H was chosen to be 10.5 mm.
  • the incision gaps 3 in the mortar layer of the masonry 1 were designed. It seemed appropriate to design the subsequent insulation in the place of the previous insulation. If this is not available, it is proposed to design the incision gaps 3 at least 10 to 15 cm above the outer walking level.
  • the choice of the respective length of the incision gaps 3 depends on the quality, the material of the wall.
  • the width of the insert element 4 corresponds to the width of the wall 1. (Of course, with a wider wall, several insert elements 4 can also be arranged side by side in the width direction).
  • the insert element 4 has a carrier grate 5 made of a thermoplastic, injection molded, which is provided with the load-bearing units 6 at the nodes.
  • the load-bearing units 6 are independent balls, which can be manufactured from a plastic which has a corresponding compressive strength (for example from “DANAMID”) or from steel.
  • DANAMID compressive strength
  • the task of the load-bearing units 6 was that, after inserting the insert element 4 into the incision gaps 3, they absorb the vertical load on the wall 1 in an even distribution, and thus prevent the structural structure from becoming damaged during and after the post-insulation work.
  • the nodes of the carrier grate 5 of the insert element 4 are designed as nests 7 which rotatably support the load-bearing units 6 (FIG. 4).
  • the mutual distance L between the nests 7 was chosen to be 30 mm (FIG. 3).
  • the fact that the balls are embedded in the nest 7 makes it easier to insert the insert element 4 into the incision gap 3, since the balls can rotate freely during this. If the balls in advance z. B. immersed in water, the rolling resistance can be further reduced.
  • the height dimension (D) of the load-bearing units 6 is selected such that they protrude above and below the support grid 5.
  • the height H, of the support grid 5 in the present case became 0.7 times the spherical. diameter D, d. H. chosen to be 7 mm ( Figure 4).
  • the support grid 5 of the insert element 4 is enclosed with a ' circumferential frame 8, here its height H 2 was 0.9 times that Ball diameter D, ie chosen to 9 mm.
  • the frame 8 is provided with at least one press-in bore 9, which lies after the insertion of the insert element 4 on the outside of the wall 1 (FIG. 1).
  • the next step of the method according to the invention can follow, in the course of which via the press-in bore 9, into the part of the incision gap 3 provided with the insert element 4, under a relatively low pressure, for. B. a post-curing material with insulation and binding properties is injected.
  • the incision gap 3 is completely filled and the insert element 4 is also embedded. If the interior is already completely filled and the injected material overflows the side gaps, the injection can be stopped.
  • the insulating and binding agent can be any known substance that is generally used for waterproofing, e.g. B. a water-insulating cement mortar (with a commercially available additive, e.g. «TRICOSAL or « REZONIT •), or a synthetic mortar, advantageously with a polyester resin as a binder (e.g. commercially known synthetic mortar under the name «POLISOL) .
  • a water-insulating cement mortar with a commercially available additive, e.g. «TRICOSAL or « REZONIT •
  • a synthetic mortar advantageously with a polyester resin as a binder
  • a polyester resin e.g. commercially known synthetic mortar under the name «POLISOL
  • the big advantage of the latter is that it sets extremely quickly (in about 60-90 minutes), which can largely reduce the time required for insulation work.
  • the compressive strength of the synthetic mortar with polyester resin as a binder is 3,000 to 6,000 N / cm 2 , which largely exceeds the compressive strength of the hard tape stones (which is 2,000 N / cm 2 ), the adhesive strength being 300-400 N / cm 2 .
  • the insert element 4 according to the invention also takes part in the load carrying through its load-carrying units 6.
  • a ball ' as the load-bearing unit 6 is not only to be regarded as expedient because of the fact that it can be inserted more easily, but also because point-like contact with the surfaces of the incision gaps 3 is made possible in this way.
  • the material injected in this way is able to make contact with the cut surfaces of the wall 1 on the largest possible area, as a result of which the best possible adhesive bond is created.
  • the carrier grate 5 and the frame 8 of the insert element 4 have been produced from a single workpiece by injection molding.
  • FIG. 5 shows another version of the insert element 4 according to the invention, in which balls are also used as the load-bearing units 6, but these are not rotatably mounted in the carrier grate 5, but are instead injection molded into a monolithic unit.
  • balls instead of the balls in this case, for. B. conical or pyramidal plugs can be used as a load-bearing unit 6.
  • FIG. 1 we have labeled the already injected insulation and binder with the reference number 10).
  • the subsequent wall insulation is shown under the top edge of the floor.
  • the wall 1 is also made of bricks (the outer walking level was designated 11).
  • the notch 3 not only traverses the entire cross section of the wall, but also continues in the thickened part of a sub-concrete 12 next to the wall 1.
  • the width of the insert element 4 was also chosen accordingly. By pressing in the insulating and binding agent 10, a wider water seal is obtained in this embodiment. This way it can be avoided! that when the wall 1 and the sub-concrete 12 meet, the moisture can seep upwards.
  • the surface of the sub-concrete is provided in a manner known per se, for example with a bituminous insulation layer).
  • the solution according to FIG. 6 cannot be used for subsequent waterproofing, but also for new insulation.
  • the insert elements 4 are placed on the wall built up to the insulation height; the part to be manufactured later that protrudes into the sub-concrete 12 can e.g. B. be covered with a U-shaped sheet metal sleeve 13, which is denoted in the figure with a discontinuous line.
  • a new brick layer is placed on the insert cement.
  • the insulating and binding agent can also be injected here via a press-in bore 9, but for this purpose at least one brick layer must be laid on the insert elements 4.
  • the sub-concrete 12 reaching the filling 14 is produced.
  • FIG. 7 shows the waterproofing of a cellar, which can be carried out using the method according to the invention either as a subsequent insulation or as a new insulation.
  • the wall seal is in a cellar wall 16 - which holds the wall 1 above a cellar ceiling 15 -, and configured over a basement sole 17.
  • a working trench 18 In order to make the basement wall 16 accessible from the outside, a working trench 18 must be provided.
  • a sheet metal sleeve 13 on the outside as well as on the inside to encase the protruding ends of the insert element 4.
  • the course of the design of the water seal is the same as that of Figure 6. (The basement sole 17 is later provided with an insulating layer, not shown, in a manner known per se).
  • the basement wall 16 and part of the wall are provided on the outside with a vertical water seal according to the invention.
  • the insert elements 4 were also used, in such a way that the insert elements 4 placed one above the other and next to each other with z. B. screw or nail connection were attached to the masonry.
  • the outer surface of the insert elements 4 is closed with a dense synthetic screen fabric 19 in order to prevent the insulation material from escaping. At the same time, however, a possibility was given for the vapors to escape. If necessary, a plastic film can be spread out under the insert elements 4.
  • FIG. 8 Another exemplary embodiment of the invention can be seen in FIG. 8, which can be successfully used in the insulation of damp rooms.
  • the water seal can be carried out later or as a new insulation.
  • the insert elements 4 were placed on a sub-concrete 12, after which “POLISOL • ⁇ was filled in as the insulating material.
  • the insulation of the inner surface of the wall 1 was carried out as we have described in connection with FIG. H.
  • a synthetic sieve fabric 19 was used.
  • the horizontal and vertical inner surfaces were clad in a manner known per se with tiles 21 glued on by adhesive 20.
  • the invention is in no way limited to wall insulation, it can be used advantageously for any water-proofing purpose.
  • the insert element according to the invention realizes an even distribution of the load. In this way, the likelihood of damage to the building structure was reduced to a minimum. Thanks to this gentle character, the invention can be used with complete certainty with subsequent isolation of art objects, etc.;
  • the insulation according to the invention does not become plastic under the action of heat.
  • the solution according to the invention satisfies the strictest requirements in terms of insulation technology and strength.
  • the insert element 4 can be made of any useful material apart from the plastic. If e.g. B. for the subsequent wall insulation according to FIG. 6, the insert element according to FIG. 5 is used, the frame 8 of the insert element can be omitted. Since in this case only the outside of the incision gap 3 is to be closed off, the application of a layer of synthetic mortar is sufficient. The mortar sets. the injection hole is made through which the injection can be carried out. In order to be able to releasably connect the insert element 4 to the adjacent insert elements, they are provided on the edges with projections or with recesses receiving the projections (not shown in the figure).
  • the insulating and binding agent used should not necessarily be a post-hardening material, since the load bearing itself is sufficiently solved by the insert elements according to the invention.
