Chipboard for use in structures or buildings

The innovation concerns a chipboard., Preferably with Boil-proof glued material, for floor sub-floors, roof cladding or concrete formwork in building squares or buildings. For economic reasons, these panels are produced in uniform, Sizes that are difficult to transport and process and are made with butted edges processed and laid on appropriate supporting documents, with several workers for transport and laying are necessary. A lot of space is required for storing these plates until they are processed.

The purpose of the innovation is to eliminate these disadvantages and to create a chipboard that meets the requirements in practice to a much better extent.

- 1 -

This is achieved by the fact that in the case of a chipboard The aforementioned type in the respective purpose for a light, labor-saving processing, a light one Transport to the point of use and a space-saving storage of adapted sizes at two or all opposite side edges are alternately provided with tongue and groove. The tongue and groove are removed from the side opposite the usage side by about 1/22 to l / l ^ Center of the thickness of the chipboard is offset angularly. For the Use as concrete formwork is recommended, the chipboard at all or some corners with embedded in the side edges and hot-dip galvanized steel angles fastened by screws or the like to provide.

In the drawing are some exemplary embodiments of the subject matter of the innovation shown schematically. It shows;

Fig, 1 to 3 an embodiment of a chipboard in Top view, long side view and narrow side view,

Fig. 4 shows the same plate in cross section with a groove on one Side wall and feather on the opposite side edge on a slightly larger scale, with a one-sided offset of tongue and groove by about l / lj5 from the center of the cross-section,

Fig. 5i, 6 and 7 other embodiments of the chipboard in different wall thicknesses with degree of displacement of the groove and Spring by 1/26, l / 22 and i / 17 from the center of the cross-section

of the plate in edge cross-sections,

FIGS. 8, 9 and 10 show a further embodiment of the particle board for concrete formwork with stiffening angles at two corners in plan view, long side view and narrow side view.

In Fig. 1, 2 and 3 is 1, the wood particle board, which is provided at its edges 2 and 3 with springs 4 and on the edges 5 and 6 with longitudinal grooves ¹ J. The tongue and groove arrangement will vary depending on the thickness of the panel and its intended use.

For example, with a plate thickness of about 19-22 mm according to FIG. 4, it is about 1/13 off the middle of the plate after that of the load side opposite side offset. With a plate thickness of about 13 mm the same offset is according to Fig. 5 about 1/26, at 22 mm according to Fig. 6 about 1/22 and with a board thickness of 25 mm according to Fig. 7 about l / l? ·

3, 9 and 10 show a chipboard for concrete formwork in which the tongue and groove arrangement is provided as in the previous figures, but also with corner stiffening or corner protection by means of screws embedded in the full panel thickness 8 fixed angle 9 ^{made of} hot-dip galvanized steel is provided. Wood chips are preferably made from wood chips that are glued in a boil-proof manner with other additives and fillers. It turned out to be very

Proven useful, the panel size for floor sub-floors about 2., 050 / 92., 5 cm for roof boarding and about 40 / 6l, 5 cm up to 4lO / j54 and for concrete formwork with about 50/225 cm, 50/200 cm, 50-150 cm, 50/100 cm, 50/75 cm, 25 / 225cm, 25/200 cm, 25/150 cm, 25/100 cm to choose and to provide the plate sizes on opposite sides with tongue and groove. Using The panels for concrete formwork are then joined by the corner protection angles made of hot-dip galvanized steel, which are inserted into the side edges are let in. On the spring-loaded side edges, the protective angles are not in the springs, but in embedded in the full panel thickness of the panels. In the specified sizes, the chipboard is suitable for the respective purpose, easy handling by one man during transport, Adapted to take up as little space as possible for laying and storage »Secure the tongue and groove connections good cohesion of the panels, regardless of the type of their support, the possibility of gluing and ax avoidance of any noises when walking on or other loads, in particular with floor sub-floors. The handy ones Sizes allow easy handling by one man for all work to be carried out with the plates and save. thus working time and costs.
