Definitions

  • the invention relates to a formwork block with two longitudinal walls, which form an outer wall and an inner wall, which are connected to one another by at least two transverse walls, which extend only over part of the stone height, with a cavity between the walls for concrete filling, and with one Insulation insert, which is arranged on the inside of at least one of the two longitudinal walls.
  • formwork blocks are increasingly used, especially for basements. They are usually made of concrete.
  • Formwork blocks can also be used very well for the complete walls of a house. In general, only the first layer of stone is placed in mortar and the rest of the wall is dry, raised like a modular system, so that even non-construction specialists can erect such buildings.
  • the formwork blocks are therefore made relatively accurately and are mostly provided with tongue and groove for joining them together.
  • It consists of lightweight concrete with an addition of foamed plastic particles and has an outer, inner wall, two end walls and a central connecting wall.
  • the cavities formed by the stone connections are shielded at least on one side with plates made of heat-insulating material. Inwardly projecting lugs or ribs can be used to hold these plates.
  • the top and bottom edges of the end walls and the connecting wall are provided with semicircular recesses in order to allow the concrete to be poured from one stone to the next in a horizontal direction.
  • Such a shuttering block is also disclosed in DE 34 32 925. It consists of an outer wall, an inner wall and two end walls. Even with this formwork block one uses an insulation insert to improve thermal insulation and sound insulation. This extends without interruption over the inside of the outer wall, the inside of the two end walls and along the recesses that are located in the end walls and are used for backfilling the concrete. This formwork block already has good thermal insulation properties, but there is still room for improvement. The same applies to sound insulation.
  • the present invention is therefore based on the object of providing a formwork block of the type mentioned at the outset which is easy to handle, has very good heat insulation properties and whose sound insulation properties are greatly improved.
  • this object is achieved in that the transverse walls - in relation to the lateral end faces of the stone - are set inwards, as a result of which the formwork block forms at least approximately an H-shape in a known manner, and in that a further insulation insert is placed over the transverse walls, which includes the transverse walls laterally and in the area of their reduced height.
  • the formwork block designed in this way is very well insulated against heat and, above all, soundproofed.
  • the basis for this is the creation of the inwardly offset transverse walls instead of the usual end walls. This creates evenly sized channels or cavities that offer ideal options for filling concrete. Because the transverse walls only extend over part of the stone height, the formwork blocks stand a row connected by the concrete backfilling. This ensures that the concrete pressure spreads evenly, thus ensuring a secure bond between the formwork blocks.
  • the improved thermal insulation of the formwork block according to the invention is achieved, inter alia, by the inwardly placed transverse walls with the insulation insert placed over them or comprising them.
  • the transverse walls of stones lying adjacent to one another on the outside of the longitudinal walls directly abut one another. In this way, there is a very large uninsulated area, with a further disadvantage that the abutting transverse walls can only be insufficiently insulated by insulation.
  • the so-called "tiled stove effect" can be particularly effective because the heat is stored in the interior of the concrete.
  • the outer wall is provided with the insulation insert and that the transverse walls on their underside are at least approximately flush with the underside of the stone, i.e. the underside of the longitudinal walls, with the further insulation insert being put over each transverse wall from above.
  • the insulation insert placed over the two transverse walls and attached to the inside of the outer wall ensures that the heat cannot be transported to the outside. In addition, almost optimal sound insulation is achieved.
  • the insulation insert for the longitudinal wall and for the transverse walls are formed in one piece. Both insulations can be done in one step.
  • the thickness of the insulation inserts for the transverse walls decreases on both sides of the transverse walls against the inside of the stone facing the building.
  • a further advantage of this reduction in width towards the inside of the stone is that at the same time there is still more space available for the concrete backfill and thus a higher static load-bearing capacity of the masonry made with it can be created.
  • a step shape, for example, would also be conceivable as a form for this.
  • the insulation inserts for the transverse walls taper in a wedge shape towards the inside of the stone facing the building. This makes it easier to manufacture the insulation inserts.
  • the width reduction of the insulation inserts for the transverse walls is at least approximately 2: 1 from the outside inwards in the area that laterally encompasses them.
  • a further advantageous embodiment of the formwork block according to the invention can consist in that, with a formwork block length of approx. 500 mm, the maximum width of each insulation insert for a transverse wall is approx. 20 to 40 mm for the area that projects laterally over a transverse wall.
  • the maximum width of each insulation insert for a transverse wall is at least approximately 30 mm for the area that laterally projects beyond a transverse wall.
  • the transverse walls each have a thickness of approximately 50 mm and a distance of 200 mm from each other, which always results in the same spaces for filling with concrete.
  • the wall thicknesses of the longitudinal walls are approx. 45 to 55 mm and the insulation insert, which extends along a longitudinal wall, approx. 50 to 60 mm.
  • each insulation insert covering the transverse walls on the upper side is approximately 10 to 30 mm.
  • each insulation insert covering the transverse walls on the upper side is approximately 15 mm.
  • the concrete filling to be filled can be made in the form of lightweight concrete.
  • a very advantageous development of the invention can be that the insulation inserts for the longitudinal wall and the transverse walls are made of polystyrene. While the filled concrete shrinks after a certain time, the polystyrene material used for the insulation inlays offers the opportunity to compensate for this shrinkage by first pressing it a bit when filling the concrete and expanding back into its old shape after the concrete filling has shrunk. In this way, cavities and thus sound and cold bridges are avoided.
  • a very advantageous embodiment of the invention can also consist in the fact that the transverse walls each have transition areas in the connection area with the longitudinal walls facing the stone top.
  • the transition area is possible in the form of a radius or in a simply beveled form for easier production.
  • the formwork block has two longitudinal walls, which form an outer wall 1 and an inner wall 2. Both longitudinal walls 1 and 2 are approximately 500 mm long, 250 mm high and have a wall thickness of approx. 45 to 55 mm. They are connected to each other at right angles by two transverse walls 3 (dashed line).
  • the transverse walls are each set approx. 100 mm inwards, so that the formwork block approximately forms the shape of an "H" and a total width of the formwork block of approx 300 mm results.
  • the transverse walls 3 are arranged at a distance of approximately 200 mm from one another in relation to the formwork block length of approximately 500 mm. This also results when laying the individual formwork blocks together, i.e. each row offset by half a side length, always the same distance of approx. 200 mm.
  • Both transverse walls 3 are connected flush with the underside of the stone on their underside and extend to a stone height of approx. 170 mm.
  • the transverse walls 3 In their connecting area, the transverse walls 3 have approx. 80 mm high, beveled transition areas 4 directed towards the top of the stone. Because the cross walls only reach the top of the stone in the transition areas, free spaces 5 are created which are useful later for the concrete filling horizontally in the longitudinal direction of the stone.
  • An insulation insert 6 is located on the inside of the outer wall 1. It has the same length and height as the outer wall and is approximately 50 to 60 mm thick Wall thickness.
  • Each insulation insert 7 covers the transverse walls 3 at the top with a height of approximately 15 mm. This dimension, which projects beyond the transverse walls 3, can also vary between approximately 10 and 30 mm.
  • the width of the insulation insert 7 decreases towards the inside of the stone facing the building, in each case on both sides of the transverse walls.
  • Each transverse wall 3 is also surmounted by the insulation insert 7 on both sides of the transverse wall 3 in a range of 20 to 40 mm, but at least approximately 30 mm.
  • the walls 1, 2 and 3 and the insulation inserts 6 and 7 enclose a cavity 8 formed in this way, which is connected to the free spaces 5 formed by adjacent formwork blocks. Due to the uniformly large cavities 8 and the free spaces 5, the concrete is poured in from the top, as is known, after the formwork blocks have been laid. This also makes the insulation inserts 6 and 7 in their position held and do not need to be attached separately to the formwork stone walls.
