Description

225 243

The invention solves new types of assembled lightweight wood shelves based on wood and plastics with increased load-bearing capacity and method of their production.

Previously known materials used for the production of cabinet shelves, in particular veneered chipboard, blockboard and plywood have a number of disadvantages. Including production effort · All the above materials require hot gluing, the use of adhesives and high-quality covering veneer on the surface. common use ⁱⁿ wardrobe, but under heavy load, eg in libraries, their deflection is greater than 5 mm, which in turn is not allowed. Layers · Their disadvantage yeah raw material intensity and complex machinery ·

These drawbacks of the previously used cabinet shelves are largely eliminated by the assembled wooden shelf according to the invention, which consists in that the horizontal part of the depth of 10 to 45 mm is formed from a hollow profiled beam made of structural tormoplastics, into which cavities alternately wedged profiled wood slats, the horizontal part is sheathed and has a right vertical clamp inserted at one end, a vertical vertical clamp at the other end, and a vertical vertical clamp inserted at the back ·

The production method consists in that the profiled wooden slats are wedged into the hollow profiled beam of structural thermoplastics under pressure of 0.02 to 1.0 MPa without the use of glue and the surface is

225 243 casing, then the vertical clips are pushed onto the ends and back of the middle thatch ·

The main advantage of the assembled wooden shelves according to the invention is their low weight »increased load capacity» »reduced deflection at long and long-term pulling, easy production without the use of glue and simple yet rigid mounting on the walls or cabinet backs * Wood and non-wood materials used for the production of prefabricated shelves are easily accessible, raw and cost-effective, because they are practically waste materials. · Adhesive-free and hot-press mounting saves both adhesive and thermal energy · Another advantage of the invention is the possibility? their retrofitting into pre-fabricated skeleton cabinets and increasing the rigidity of shelf attachment to the sides and cabinet back ·

The overall composition and arrangement of prefabricated lightweight wooden shelves with increased load capacity is shown in the accompanying drawings, in which Fig. 1 is an overall view and Figs. 2, 3, 4, 5 and 6 represent different embodiments of shelf details.

Example 1:

The supporting structure of the horizontal part 1 is formed from a hollow profiled beam 5, which is made of tough polystyrene of the KRASTEN-562 type. Pressed 0.02 to 1.0 MPa profiled wooden slats 6 of 8 to 16 mm thick, made of dried spruce wood, are pressed into the recesses in the sections. The construction and covering layer of beech three-layer thin plywood 9 is fixed to the surface. The right vertical clip 2 is slid to one end, the vertical clip 3 is slipped to the other end, and the side vertical clip 4 is slid onto the rear wall. The clips can be? made of metal sheet or polyamide or tough polystyrene · Pushing the clips creates an assembled, lightweight wooden shelf with increased load capacity, fig.

Example 2;

The horizontal part 6 in this case is made of two hollow profiled beams 5 of tough polystyrene, preferably

225 243 of KRÁSTENU-562, forming a load-bearing structure. The hollow profiled beams 5 used form holes of hexagonal shapes, fig. 5, or hexagonal shapes with horizontal bars, fig.4. ^M in which the cavities pushed together. the resulting solid central panel without the use of glue, which is sheathed on the sides samolopiacou mikrodyhou 7 * Hrabkov 0.2 to 0.8 mm, Figure 4. the resulting lightened joint board is assembled according to FIG. 1 per shelf according to the invention Example 3:

In the case of a hollow profiled beam 5 of tough polystyrene, preferably of KRASTEN-562, according to FIG. 6, two solid profiles of synthetic material 11, preferably of S1LAMID, 8 are inserted into the hollow base profile of the horizontal part 1, preferably of S1LAMID, 8 ”U”, rakes 5 to 35 mm without the use of glue. A rigid combined hollow board is formed which is coated with a self-adhesive micro-fabric 2 or a self-adhesive foil 8, e.g. wallpaper with wood imitation, fig.6. Further assembly of the shelves is done in the same way as in example 1 ·

The assembled wooden shelves according to the invention can be used? to a greater extent in the manufacture of furniture, e.g. in the production of bookshelves and kitchen cupboards that are exposed to prolonged heavy loads.

Claims (3)

OBJECT OF THE INVENTION 225 243 1 «Prefabricated wooden shelf and method of manufacture based on lumber and structural thermoplastics, shaped as a double-sided and centrally supported beam, consisting of a horizontal section of vertical, lava and lateral clamps, characterized in that the horizontal section (1) of depths 10 to 45 mm is made of a hollow profiled beam (5) made of structural thermoplastics, into which cavities are alternately wedged profiled wooden slats (6), while on the horizontal part (1) the right vertical clip (2) is pushed on one horse, on the other end the vertical lava clamp (3) is slid in and the rear vertical lace clamp (4) is slid on the back. An assembled wooden shelf, characterized in that the horizontal part (1) with the wedged profiled wooden slats (6) is coated with a self-adhesive micro-ply (7) or a self-adhesive foil (8) or a thin plywood (9) or a synthetic material (10). 3.
