Definitions

  • the invention relates, according to the preamble of claim 1, a supporting structure for the construction of buildings, preferably of buildings, in dry and self-construction with components from the timber industry, the structure is formed from a variety of individual wood components in skeleton construction, which makes it From a support structure of the timber frame construction and / or plastic construction differs gravely and can be clad as a new wooden structure with components from the plastic industry, preferably from the Dämmstoffbau, in the composite system.

  • construction refers to the construction of buildings and buildings. This includes both the design process and the result, ie the structure of the components in the finished structure, here in particular the wall construction.
  • structure refers to a man-made structure with a resting contact with the ground, while the term “building” is a sub-concept of a building.
  • a building is created by the construction of a permanent construction on the ground and consists of individual components. Components in construction are individual parts, individual elements or individual components that make up a building.

  • the building block assembly consists of a framework consisting of a plurality of individual building blocks connected by plastic material, e.g. Brick, is made.
  • the brick bricks are connected instead of mortar by means of adhesive and have a very small bond gap between the blocks.
  • the bricks have hollow chambers which are filled with a PUR foam or other insulating material.
  • the disadvantage of this design is that a large amount of environmentally harmful polyurethane foam must be used to connect the blocks and the use of low temperatures and frost is suitable only conditionally.
  • a kit of cubic plan blocks made of cellular concrete and rod-shaped connectors made of wood for the construction of structures is described in the disclosed composite system DE 298 04 074 U1.
  • the wooden connectors are used instead of mortar to connect the plan blocks with each other and for the construction of dry masonry.
  • the abutment surfaces of the plano blocks have corresponding profilings, which engage in a form-fitting manner in the wall composite and have slots for the connectors on the side surfaces.
  • This composite system is suitable for building a drywall support structure for cold-season buildings.

  • the scaffolding is constructed in dry construction, but its spaces are not.
  • the interstices are filled with a wood-clay composite or a brickwork.
  • Each space of a wooden framework represents a compartment, the so-called Gefach.
  • the Gefach comes in the half-timbered building (half-timbered house), the so-called skeleton structure made of wood in stand construction, often before.
  • this construction has the disadvantage that the compartments in the cold season can not be filled in mortar technique and the shell must therefore rest.
  • a further development of the stand construction is the so-called wood prefabricated house.
  • a prefabricated timber house is a building that is not industrially prefabricated on site but in a factory and partially delivered to the construction site where it is finally assembled in dry construction.
  • the term prefabricated house means that the building is not built on site, but prefabricated in a factory.
  • Two types of construction, the timber frame construction or the wood panel construction can be used in the production. Therefore, in the wood frame and wood panel construction, the prior art is to be understood to understand the inventive task and solution.
  • Timber frame construction is one of the most important modern timber construction systems and is a further development of timber frame construction. The features are the predominant use of two-inch planks.
  • a special form of timber frame construction is the Timber panel construction, in which the wall and ceiling elements in the manufacturing plant as far as possible, as described below, are prefabricated.
  • the timber frame construction is distinguished, in contrast to other timber structures, such as the block construction or the timber construction, the fact that a wooden frame with vertical beams and horizontal struts vertical support function takes over and the horizontal stiffening is done by plate-shaped wall building materials or diagonally applied boards.
  • Timber frame construction has long been known in North America, Canada and the Nordic countries as "Balloon Framing" and "Platform Framing".
  • the main feature of the "Balloon Framing" is the wall posts or columns that extend through the floors.As a support for the timber layer, a wooden screed is placed at ceiling height, the beam layer is laid on the side and fixed to the support stiffened or externally planked with boards diagonally
  • the outer wall inside, inner walls and ceiling undersides are usually covered with thin wooden strips, which serve as plaster base for gypsum plaster.Today mostly plasterboard, and gypsum fiber boards (eg known as Rigips plates) are used.
  • gypsum fiber boards eg known as Rigips plates
  • platform framing the raw construction - unlike the “balloon framing” - is constructed floor-to-floor and completed with a platform on which the next floor or the next storey is built.
  • the wooden supporting structure of the walls consisting of wall posts which support the structure form, together with upper and lower straps, is initially prefabricated lying on the respective floor, then set up and connected to each other by means of an additional upper chord.
  • On the outside and on the floor slabs are applied plywood or the like. The rest will be boarded with gypsum plasterboard after completion of the shell.
  • the degree of prefabrication is relatively high and such a timber stand construction can be done in the cold season.
  • these systems for building rough buildings in wood construction have the disadvantage that they are not suitable for DIY and too much machine and a staff effort in the construction of timber structures is necessary.
  • Wood construction is an old, independent field of expertise that distinguishes itself from other areas of construction, such as masonry construction, with its specific techniques and materials.
  • wood panel construction the flat, self-supporting wooden structures are referred to as panels.
  • the wooden panels are composite structures made of ribs, which are covered with nails, staples, screws or glue with different building materials, such as solid wood or wood-based materials.
  • a wooden frame which forms the structure, created. After the construction, the wooden frame becomes a wood panel through insulation, fixtures and final planking.
  • the spatial structure is composed of individual wooden panels. From the individual wooden panels, large panels in building dimensions are then assembled in the manufacturing plant, the sizes of which are determined by the standard formats of the paneling materials. They represent the supporting structures (walls) of the entire structure, including all essential installations, and are prefabricated at the manufacturing plant, as indicated above, and then transported to the construction site with heavy vehicles. After delivery to the construction site, the large panels are assembled during assembly using a crane to form a building. The Assembly of a prefabricated house can be done in the cold season.
  • DE 296 18 705 U1 discloses a building system with a support structure made of wood, wherein the interspaces of the support structure are filled with form stones.
  • the wooden stand of the support structure of parts of the neighboring mold blocks are covered to the outside on the outer walls of the building.
  • the arranged on both sides of a wooden stand shaped stones thus overlap the wooden stand on the outside.
  • a gap between the wooden stands and stones is avoided, which creates a direct connection between the building interior and the outside of the building.
  • the installation of the support structure is not possible in self-construction.
  • the state of the art does not include any real DIY that works without machines such as concrete mixers, cranes and similar machines.
  • Another disadvantage is that the compartments have no, in the vertical direction continuous cavity, but they form a variety of cavities, which are not suitable for the use of blow-in insulation, because the compartments do not allow a continuous insulation layer.
  • the invention is therefore based on the object to the above-mentioned disadvantages of the prior art, such as the use of structural engineering of the classic masonry building blocks with brick (sand-lime brick, aerated concrete stone, etc.) and their bonding materials (mortar, adhesive, polyurethane, seals between molded bricks etc.) and / or connecting elements (groove, spring, dovetail, metal pipes as columns, etc.) as a supporting structure to dispense, because these components, for example not be made from renewable resources and not in the cold season, z.

  • the invention solves these problems with the characterizing features of claim 1.
  • the invention therefore proposes a completely new construction system for structures constructed in timber construction.
  • the structure of the invention must dispense with the aforementioned disadvantages and should still be provided in dry and self-construction and with a continuous thermal barrier coating.
