Description

Ceiling structure 72569

The invention relates to a ceiling structure in which acoustic or other interior panels are placed on a frame formed of inverted longitudinal and, if necessary, transverse T-lis-5, which frame is fixed to the roof structure or to the upper part of the walls.

The frame of the most commonly used ceiling structure is formed by metal T-strips. Using these known moldings, one is practically bound to a few interior-10 moldings. For example, attaching a wooden strip to this metal strip is a possible, but in practice quite cumbersome operation. A groove must be milled in the trim strip for the binding bracket of the trim strip and the T-strip. The entire frame is usually suspended from the roof structure by means of iron bars or strips.

DE 1926 685 discloses a type of roof and wall structure in which wooden slats are used as a support structure. The various parts are attached individually to the wall and to the structure to be manufactured, as is typically the case with wooden structures. According to this, a frame is formed from the separate strips and strips, on top of which and inside the shaped interior panels are placed.

Installing a ceiling, especially directly on a concrete ceiling, is very laborious using known working methods. 25For trim strips, the subfloors are first attached to the concrete roof, often by gluing, and often each trim panel is attached individually to the concrete, after which the trim strips are installed by screwing or nailing them to the subfloor. The method requires a lot of measurement and cutting of the strips during installation and causes bumps in them.

The present invention seeks to create a ceiling structure which is simple in terms of installation technology and offers in practice a wide range of possibilities for selecting the visible interior strip list 35 according to the rest of the interior design style. In particular, it is an object of the invention to give the designer a free hand to choose an interior molding from a wide range of available moldings without complicating the manufacturing and installation work. These advantages of the invention 2 72569 are achieved by implementing a ceiling structure according to claim 1. In addition, the two-part Τ'-strip, the combination of the rib plate and the strip plate claimed by the claim does not twist despite moisture fluctuations.

The invention does not only relate to the choice of material per se, but in practice it makes it possible to implement a large ceiling system with a simple manufacturing technique. Such a system only enables versatile material options, because the ceiling structure according to the invention does not waste material in order to achieve versatility, but both parts of the T-strip belong to the load-bearing structure.

The frame of the ceiling structure is most preferably formed as defined in claim 5 by milling teeth at the end of the transverse strip ribbed plate, one of which fits into a hole in the longitudinal strip ribbed plate and the other into a groove machined in the strip plate. First of all, the structure is advantageous from a manufacturing point of view, as there are few work steps required. In addition, such a structure has installation-20 technical advantages. The crossbars can be locked by turning them to their final position, where they bind the joints in all directions.

With the aid of the ceiling structure according to the invention, small standard dimensional differences between the devices to be installed on the ceiling, inside the frame, mainly the luminaires and the interior panels can be adjusted by choosing a sufficiently wide strip panel. In the past, this has not been possible in practice, as the wide list available in general could not be combined with other interior design styles due to small choices. A wide 30 metal T-rail would have required a separate set of interior moldings of this width, which would have caused an unreasonable cost to the system.

The ceiling structure according to the invention is particularly advantageous when it is fastened directly to the roof structure, e.g. directly to a concrete roof. In this case, ceiling-mounted U-brackets are used to fasten the frame, between the branches of which the ribs are pushed, whereby the teeth in the branches lock the rib plate to the U-bracket. In this way,

The invention will now be illustrated by reference to the accompanying drawings, which show some embodiments of the invention.

Fig. 9 shows a U-bracket for direct ceiling installation Figs. 10 and 11 show another embodiment of a ceiling structure corresponding to Figs. 1 and 2. 2 ° The ceiling structure consists of a frame assembled from T-strips and decorative panels 5 resting on it. Figure 1. The short transverse slats rest at their ends on the longitudinal slat and the whole frame is supported on the longitudinal slat by means of suspension members made of iron-25 wire or strip attached to the load-bearing roof structure.

; The T-strips of the ceiling structure consist of two parts, a vertical ribbed plate 1.3 and a horizontal ribbed plate 2.4, Fig. 2. The ribbed plate is most preferably plywood, which as a material offers good strength and machining properties. The height of the fin plate 1.3 is selected according to the span used.

; The strips are connected to each other by means of teeth 14 and 15 at the end of the transverse strip rib plate 3, which correspond to a hole 16 in the longitudinal strip rib plate 1 and a groove - 35 17 in the strip plate 2. The installation method is described below.

Both types of moldings are made of similar moldings; O-blank. The ribbed boards 1 and 3 consist of a narrow plywood board, into which holes 16 are drilled at regular intervals. When making a longitudinal strip, the strip blank is cut to a long extent and hole-pin arrangements 18 are further formed at the ends of the strip to center the extension strip. For the transverse-5 strip, the strip blank is cut to short dimensions and the end of the strip is milled as shown in Fig. 4. This is done on one machine in the same work step. This simple method of fabrication, which involves only a few steps, allows the designer to choose from a wide range of available interior moldings for the visible strip-10 winter board. Production can be adapted quickly, efficiently and at low cost to meet demand.

The connection 9 between the rib plate 1,3 and the strip plate is realized by some notch connection, Figures 3-6. The straight notched joint of Fig. 3 is the most economically advantageous from the manufacturing point of view, but requires a high strength of the gluing seam.

The two-part construction of the T-strip effectively prevents the strip from twisting in spite of fluctuations in air humidity. The 3-groove profile of the strip plate further reduces this 20 natural twisting of the wood.

The installation of the preferred ceiling according to Figures 1 and 2 takes place by first installing the suspension members on the ceiling and then attaching longitudinal strips to them. The transverse slats are first placed between the longitudinal slats 25 so that the tooth 14 at the end of the rib plate protrudes into the hole 16 in the longitudinal slat rib plate 1, Fig. 7. The transverse slat is then turned to its correct position. . In general, the interior panels 5 can be placed in a completely finished frame.

When installing the ceiling structure, it is usually necessary to adjust the different standard dimensions of the luminaires 7 of the interior panels 5 j, Fig. 8. The standard length of the previously used s t a n -35 is 120 cm, but in the luminaires it is 125 cm. Both can be fitted to the ceiling structure according to the invention without cutting the strip when a wide strip of more than 5 cm is used in the T-strips. This 2.4 "margin" of bandwidth

5,72569 can also be applied to other devices, such as air exchange components.

In direct ceiling mounting, the internal ceiling structure according to the invention offers a very simple installation 5, Fig. 9. U-brackets 10 with teeth 12 biting the ribbed plate are installed on the concrete roof. In the installation phase, the ribbed plate 1 is pushed into the first tooth 12, keeping the frame up . The ribs 1 are then pushed all the way to the bottom of the U-brackets and the ceiling is ready.

The U-brackets 10 are mounted on the ceiling with screws 13 for which holes have been drilled in the ceiling. The dimensional inaccuracy of these bores can be eliminated by means of a slot in the U-bracket 10, which allows the U-bracket 10 to be adjusted laterally with respect to the hole.

The ceiling structure according to the invention can be implemented in many ways. Figures 10 and 11 show another way of deviating from the structure of Figures 1 and 2 with respect to the locking structure of the slats. Here, the strips are locked to each other only by means of a dovetail notch connection between the rib plates 1 and 3, in which the notch 8 is machined into the rib plate 1 of the longitudinal strip.

; The transverse strips adjacent to the wall can also be supported f by means of a strip 6 fixed to the wall.
