DE3020405A1 - Underfloor heating system shaped floor panel - has cruciform slots in round knobs in eight separate sections - Google Patents

Abstract

The shaped panel provides sound insulation, load bearing capacity and fixture, in laying a hot water and heating system in a floor. It is divided into eight longitudinal and transverse units, in each case beginning and ending with cut-out semicircular knobs of 12.5 cm. dia., 20 mm. high. Cutouts in these run at right angles to the panel, producing cruciform slits 18 mm. wide and 20 mm. deep in circular knobs. Intervals between knob centres are 25 cm. Squares set on tips contain four knobs each, with axial intervals of 25 cm. between opposite knobs. A cutout measuring 40 x 5 mm. runs diagonally between knobs, providing optimal contact with the heating pipe when flooring is laid. This provides effective sound insulation, easy pipe laying without additional fixing elements, and good contact.

Molded plate for hot water underfloor heating

The invention relates to a molded plate made of rigid polystyrene foam, which is used to lay the Pußbodenheizrohres, without the need for additional fasteners.

Various types of polystyrene molded panels for underfloor heating are known, The invention consists in that the rigid foam board according to DIN 4108 with a coefficient of thermal conductivity of 0.04 W / mK circular knobs with a diameter of 12.5 cm and one Height of 20 mm. These circular knobs are cut out in a cross shape. The recesses run at right angles to the mold plate in such a way that the cross-shaped slots have a width of 18 mm and a depth of 20 mm. These are rounded at the tapering knob edges with a radius of R = 8 mm. The standard size of the mold plate is 50 χ 100 cm with a total height of 45 mm.

This shaped plate has a double function, as it is used for sound insulation and at the same time represents the support and fastening element for the heating pipe. As sound insulation, it has a total thickness of 20 mm. If the sound insulation is to be increased, a second layer of mineral wool or impact sound foam SE must be laid underneath, as is known. The weight of one mold plate is 0.485 kg. The compressive strength of the rigid foam is 1.4 kg / cm. The 16 mm thick BT pipe from Rhiatherm is ideally suited as a heating pipe. This pipe can be laid cold and needs at 293 K = 20 ⁰ C as "Uegeradius R = 6 χ outer pipe diameter,

In the invention it was assumed that a pipe spacing of 12.5 cm for even heating of a room.

enough. The reference size of the mold plate is 50 χ 100 cm. So devoted There are semicircles left open on all four sides, and those afterwards with the hollowed out semicircles when the tube is inserted the directly adjoining panels represent a solid composite system.

The circular knobs between which the pipe is laid in a straight direction clamped, all lie with their outer edge on a straight line with a distance of 2 χ 12.5 = 25 cm. That Pipe is inserted between the left and right circular knobs and runs in a slightly wavy line and jams firmly between the individual knobs. To perform the turning or end loops with the required bending radius can, the circular knobs have received the cross-like recess, so that a loop at every point in the room of the pipe can be done. The laying of the pipe is then as follows: The pipe runs in a slightly wavy shape between the individual knobs. As can be seen from the drawing, the pipe runs through the central axis of three recessed circular ones Knobs in order to obtain the required bending radius and is then returned in the opposite direction. This is repeated at all end points. The knob height of 20 mm is sufficient for a tube with a Diameter up to a maximum of 16 mm, as the clamping effect of the pipe is only in the central axis. This ensures, among other things, that touches as much of the pipe surface as possible with the screed to be applied later. There is also a diagonal between the circles a 40 mm wide and 5 mm deep recess is arranged so that the screed can also optimally connect under the pipe at these points can.

If a lower heating output per square meter of floor is to be achieved, a row of knobs is simply skipped over, and then will be relocated according to the description above. This knob arrangement also allows the heating pipe to be laid in a spiral from the center of the room.

The features of the invention are in particular:

- the sound insulation

- The arrangement, size and type of recess of the circular knobs on the plate for efficient laying of the heating pipe ■ With no additional fastening elements

- The recess running diagonally between the circles, which allows optimal contact between the screed and the heating pipe

- the possibility of turning or final grinding of the heating pipe to be laid in such a way that the bending radius of the pipe is always guaranteed

Claims (1)

Claim Molded board as sound insulation, carrier and fastening element for laying hot water underfloor heating, characterized in that that the square meter floor molding is divided into eight longitudinal and transverse units, beginning and ending each with recessed semicircular knobs of 12.5 cm Diameter and 20 mm height. The recesses in the circular knobs run at right angles to the mold plate, namely such that the cross-shaped slots have a width of 18 mm and a depth of 20 mm. These are at the expiring Knob edges rounded off with a radius of R = 8 mm. In the longitudinal direction and in the transverse direction, the distance is between the centers of successive knobs each 25 cm. This results in squares turned upside down, in which have four knobs recessed in the shape of a cross, whereby the opposing knobs have a center distance of 25 cm. Between the circular knobs there is a diagonal cutout of 40 χ 5, so that the floor screed to be applied later has optimal contact with the heating pipe. 130049/0426 ORIGINAL INSPECTED
