Definitions

  • the invention relates to a prefabricated Wall element made of chipboard.
  • Wood chip concrete is one Mixture of wood chips and cement as a binder.
  • the Wood chips are due to the penetration of mineral Fine materials pre-mineralized in the wood pores.
  • known concrete wall which from Chipboard panels exist as lost formwork set up at a distance from each other in the vertical direction and be filled with concrete.
  • Formwork blocks made of chipboard known, which with a Internal or external insulation is provided, see Lohmeyer building physics, Edition 1995, page 135, publisher B.G. Teubner, Stuttgart.
  • the known wall systems are still in need of improvement regarding the thermal insulation value and Vapor diffusion.
  • the known systems not ecological in production. They are too expensive and therefore uneconomical and have a high Volume weight.
  • the object of the invention is a prefabricated Wall element to create that the recorded defects does not have.
  • the invention provides a solution to this problem
  • Prefabricated wall element made of chipboard consisting of a mixture of cement and pre-mineralized wood chips with a pre-mineralized timber frame as static load-bearing part in the composite system.
  • the wooden truss frame is preferred Poured inside in the chipboard concrete.
  • Portland cement is preferred as the cement (Blast furnace cement) used.
  • the wood chips and the Wooden truss frames are preferably made of softwood.
  • swarf with a Diameter from 1 to 4 mm and a length of 20 to 50 mm used to achieve high pile porosity for good insulation.
  • the above mentioned chips are mixed with fine chips to Example sawdust from 0.1 to 1 mm in diameter and one maximum length of 3 mm.
  • the vertical connection to the vertical End faces of the wall elements are preferably made via groove and Spring connections with the insertion of a hardwood strip in aligned grooves in the exposed Outer surfaces of the adjacent vertical posts of the Truss framework. Similarly, the Corner connections are carried out.
  • the Wood chip concrete preferably over the horizontal Upper chord of the truss frame pulled up to form a Paragraph for receiving the ceiling beams and for Avoidance of thermal bridges.
  • the wall elements are manufactured horizontally.
  • the wooden truss frame at a distance from the floor in one Formwork bolted to form the groove and Spring connections and paragraph for the Ceiling construction is shaped.
  • the wood chip concrete is then filled into the formwork around the truss frame and after the formwork frame is removed after hardening.
  • Suitable wood chips are used to manufacture the chipboard concrete from coniferous wood pre-mineralized by penetration of mineral fines in the wood pores (absolutely without Pollutants). Corrosion-promoting components, such as Chlorides must not be used.
  • As a binder only normal cement according to DIN 1104 is added.
  • Pre-mineralization is carried out in aluminum sulfate Mixing ratio 10kg aluminum sulfate to 1000 ltr water used. In the same way, the Pre-mineralized timber frame.
  • a Formwork piece bevelled on both sides on the side facing surface of a post of the truss frame be attached to form a laterally opening, bevelled on both sides in one Side surface of the wall element for producing a Corner connection between two adjacent wall elements. It can wall elements with door cutouts and Window cutouts can be made with roller shutter boxes.
  • the top, bottom and side formwork for the Roller shutter box are preferably made in two parts bevelled by 45 ° at their abutting ends, so that the formwork can be easily removed.
  • This formwork preferably remains as a transport lock in the finished part and is only opened after assembly the construction site away.
  • the wall elements according to the invention are suitable for vapor diffusion, breathable and fire resistant, she are economical to manufacture and assemble can be made quickly and without complicated equipment become.
  • the wall elements according to the invention a low volume weight and are therefore characterized through good logistics.
  • Wall elements according to the invention have a k value of 0.285 W / qm x K with a thickness of 30 cm in comparison to a k-value of 0.474 W / qm x K with a thickness of 30cm of the jacket concrete walls mentioned at the beginning. Weigh also the wall elements according to the invention with a thickness of 30 cm about 160 kg / sqm while the well-known shell concrete walls weigh about 450 kg / sqm at a thickness of 30 cm.
  • Figure 1 shows a wall element W with a Window cutout F and a door cutout T. Vertical sections along the lines A-A, B-B, C-C and D-D are also shown as well as a horizontal section along the line E-E.
  • the timber frame frame R consists of a lower flange 3 and an upper flange 2 and the post 4.
  • the truss frame R also has a window parapet 5 as well as middle horizontal intermediate struts 6.
  • the Truss frame R is dashed in the elevation of Figure 1 shown because it is poured into the wood chip concrete B. As can be seen, the wood chip concrete B is on the outside pulled up at 7 with respect to the top chord 2 to a to create a suitable support for the ceiling beams 18 and To avoid thermal bridges.
  • Figures 2 and 2a show a prefabricated wall element in elevation (Figure 2) and in section along the line A-A ( Figure 2a).
  • the vertical posts are labeled 4.
  • 5 is the Recess for the ceiling beams 18.
  • 4 is that Balustrade wood.
  • the roller shutter box is labeled 9 and 8 are the wood chip concrete infills.
  • Figures 3 and 3a show the formwork for the Roller shutter box 9 in vertical section ( Figure 3) and in Cross section ( Figure 3a).
  • the vertical posts of the Timber framework are designated 4. 8 denotes the Wood-concrete fills.
  • the shutter box formwork has an upper formwork panel 16, a lower formwork panel 11 and side formwork panels 17. This Formwork panels are each made in two parts and on their joints inclined by 45 °. Holding strips 15 are on the upper ends of the side formwork panels 17 and the underside of the upper formwork panel 16 screwed tight, for example using self-tapping screws 14.
  • the lower one Formwork panel 11 for the roller shutter box also in Longitudinally divided into two pieces, which on their Joints are inclined at 45 °.
  • the top formwork panel 16 is also bevelled on both sides. Also are the upper ends of the side formwork panels 17 beveled at the top. Through these bevels, the Simply remove formwork panels 11, 16, 17.
  • reference numerals 13 show the side shuttering panels for the window opening 8.
  • Figure 4 shows the attachment of the Truss frame R in the outer formwork for filling the liquid chipboard concrete.
  • the truss frame R is in Distance from the floor using screws 17 on the formwork S attached.
  • the wall elements are at their vertical ends joined together via tongue and groove connections 18, such as the 5 shows, for the wall elements W1, W2, W3.
  • a Hardwood ledge 20 is in grooves aligned with one another the exposed vertical surfaces of the vertical posts 4 used.
  • a corner connection is shown between the wall elements W1 and W3 and between the wall elements W1 and W2 is a connection between the end faces of the Wall elements shown.
  • the outer formwork S is designed to form the Tongue and groove parts, see Figure 4.
  • a formwork element S1 is on the top surface of the left post in Figure 4 attached to form a groove in the upper side of the Wall element W1 for the corner connection.
  • the tongue and groove parts are chamfered on the side, e.g. B. at an angle of 45 ° so that the finished wall element can be easily switched off.
