Channel for underfloor installation

The innovation concerns a duct for underfloor installation, which is made up of wall and cover components in a modular design and is adjustable in height.

An underfloor duct on the market based on the modular principle consists essentially of a trough which is composed of profile elements. Arms attached to the sides lead to anchors embedded in the floor: with screw threads on which they are held between nuts, height-adjustable mounting. This means that the entire duct can be raised or lowered during assembly; .. CH-PS 504 600 relates to a similar but simplified duct. With such ducts, the space under the tub is lost when the duct is raised to the upper edge of the finished floor .

In another known housing for underground lines, side walls with end flanges are located on a base part on the upper face of which profile bars are supported by means of leveling screws (DT-GM 6 949 527). The side walls must therefore be made so massive over their entire length that they are exposed to loads, especially in the assembled state Can derive soil.

There is also known a cable duct for high-voltage and telecommunications installation, in which covers are held by profile rails ₅ which in turn are supported by jaws that are held vertically adjustable at the sides by stands. The stands are held displaceably in traverses. The inside of the ducts form walls between the trusses and the

Profile rails are clamped in (DT-OS 2 244 596). The saving of a rear wall by holding <5 'ο side walls and a front cover _J by means of support brackets or traverses is generally known (DT-AS 1 225 726).

The innovation is based on the task of “a duct for underfloor installation to improve according to the modular principle so that with a few basic parts and assembly handles an already in the assembly, i.e. if the duct is not yet embedded in the ground, a stable and resilient duct is created. Bs are therefore arrangements to avoid those from the support of the cover to the base part on the height-adjusting organs or the side walls Bending forces are to be transmitted.

The solution to the problem described is that height adjustment devices each with their foot, which is guided on cross rails on the floor, hold the side walls and on their Store the head profile bars, which overlap the side walls in height and accommodate duct covers on their upper side. As a result, the height adjustment devices derive loads from the support of a cover perpendicular to the base without Bending moments are to be taken over. In addition to its width, the channel can also be used on the construction site without any special additional parts can be slightly varied in height and uses the entire available space, for example in the screed. With the lateral overlap in height, the part made of stronger material is arranged on the outside, so that this Component can be supported by applying.

The height adjustment device can in principle consist of a threaded sleeve exist, which is held with its foot longitudinally displaceable a cross rail. It is advantageous if the height adjustment device a backward angled part of the side wall holds between its foot and the cross rail and on the head side receives a screw with a bearing surface.

Profile bars ©, which are located on the outside, are particularly favorable T-groove on>. "V.1 sen and a groove on the inside, which is from a imaginary way opposite T-groove remains when the profile is cut along the shaft of the T, and that a downwardly facing tab is formed on the inside of the channel. This profile is not only simple and clear, but offers a particularly wide range of possibilities for use for simply shaped carpet strips. On the outer T-slot bars can be used in a known manner To connect channel sections together.

Assembly is further facilitated if the cross rails are provided with dimension grooves that act as locking means with the angled Part of the sidewall work together.

The invention is to be further explained with reference to exemplary embodiments shown roughly schematically in the drawing:

In Figure 1, a channel is shown in the installed state in cross section.

In Figure 2, a single height adjustment device with its surroundings is shown on a larger scale.

In Figure 3 is a longitudinal section in a height adjustment device reproduced.

In Figure 4, a stepped cross section through a built-in channel is shown in perspective.

In the figures 5 to 10 cross sections are shown in a profile bar with different types of carpet edges.

In Figure 11, a cross section is shown in the manner of Figures 5 to 10, but with an inserted U-profile and a height adjustment screw in the profile bar, with which a lid or a cover to floor coverings of different thicknesses in his Height can be adjusted. -4-

In Figure 12 is the end engaging in a profile bar a bracket at a cut see the figures 5 to 11 reproduced.

The channel 1 of Figure 1 is made of the following components in Modular principle formed: Height adjustment devices 2 are each guided with their feet 3 on cross rails 4 on the floor. With their foot 3, the height adjustment devices 2 hold a backward angled part 5 of the side wall 6. On the Head of the height adjustment devices 2 store profile bars 7 which overlap the side walls 6 in height and on their Take up the top of the duct covers 8.

The floor can consist in the usual way of the bottom part 9 made of raw concrete and the bottom part 10 made of screed. A floor covering carpeting, for example, is denoted by 11. The carpet is placed on the edges of the duct cover 8 protected by carpet edges 12 and 13.

Partition walls or U-shaped troughs can be placed on the cross rails 4 14 to be installed in order to divide the channel 1 into different zones, for example in zones for power cables and in zones for telecommunication cables, to subdivide. The cross rails 4 can be fastened to the floor by means of screws 15.

During assembly, the height adjustment devices 2, which are guided on the cross rail 4, apart- oa ^ r move together and thereby adjust the channel width. The height adjustment devices can in principle consist of a threaded sleeve 16 exist in their foot by means of a screw or a bolt 17 in an elongated hole in the cross rail is held. On the head side, the threaded sleeve receives an adjusting screw 18 with a support surface for the profile bar 8.

The width of the channel can be adjusted particularly easily during assembly if the cross rails 4 with
