DE202006007037U1 - Floor drain for installing in floor coverings has a cover over a standpipe and a spacer to adjust clearance between the cover and the standpipe - Google Patents

Abstract

A cover (13) lies over a standpipe (17) with a clearance. Fitted between the cover and the standpipe, a spacer (14) adjusts a defined clearance between the cover and the standpipe or other parts in a floor drain. The cover has a protruding part, a peg, a pin, or something similar on its underside top wall, onto which the spacer can be fixed with a center hole.

Description

The The invention relates to a floor drain, in particular for installation in Floor slabs, with a distance above a standpipe Bell, and at least one spacer, which defines a Distance between the bell and the standpipe or other parts of the floor drain established.

at in buildings occurring fires can Flames and smoke can also reach floors on the floor through floor drains. Usually The floor drain is provided with an odor trap. there The wastewater is up to an upper peripheral edge of a standpipe. Above the standpipe is held a bell whose lower peripheral edge and the Level of the wastewater or the upper peripheral edge of the standpipe lies.

task The invention is the creation of a floor drain with fire protection. In particular, it should be prevented that smoke through the floor drain or even flames can get into the room in question.

Of the Floor drain according to the invention is characterized in that the spacer under the action of heat yields, especially at less than 100 ° C. In high heat, this lowers the Bell on the standpipe and closes this. The spacer is constructed, also by suitable material selection, that preferably already heavily heated water is sufficient to the spacer to yield. Possible is a training of thermoplastic. It can also be sufficient if the spacer is only partially off when exposed to heat is yielding plastic. Is appropriate a material that is more than 80 °, especially more than 90 ° sufficient becomes soft, leaving only very heated water in the standpipe or even only water vapor arising to soften the spacer.

advantageously, the spacer between bell and standpipe is arranged, in particular between a bottom of a wall of the bell and an upper peripheral edge of the standpipe. Alternatively, you can the spacer also between bell and a heel of a drain body of the Floor drain arranged. The important thing is that at least indirectly a defined distance between bell and standpipe results.

advantageously, is the spacer at an underside of the top wall of the bell arranged, in particular kept. Preferably, the bell has on the bottom of a projection, pin or the like, on the spacer with a particular central bore is pluggable. The easiest is a vote between pins and bore such that no additional fasteners required are. Possible but is also a fixture on a pin with a locking ring or a screw or the like. Especially useful a centering of the spacer on the bell. The lead or pin on the bottom of the bell allows this.

advantageously, the spacer is at least partially on the upper circumferential Edge of the standpipe on. Also can Means be provided for centering the spacer relative to the standpipe, about heels or recesses on the spacer.

advantageously, the spacer is star-shaped formed, in particular with three arms, the ends preferably rest on the upper peripheral edge of the standpipe, and with a central part, which in particular the already mentioned bore having. The arms are as thin as possible, around the for the effluent water does not reduce effective cross section.

Conveniently, the spacer is arched formed with a central upper area attached to the bell abuts and an outer lower Area (eg, the arms or their ends), at least partially rests on the standpipe.

advantageously, The spacer is made of polyethylene or another Heat yielding Material. Preference is also given to materials that in the further Heat or even burn as little toxins as possible or in conjunction with water and / or air none or as possible form little toxins.

advantageously, the bell is particularly heavy trained, especially with a Weight of at least one kilogram. Preferably, the Bell made of stainless steel and machined at the bottom. As a result, a good sealing effect on the standpipe is possible.

advantageously, the bell has an axial distance with its lower edge a paragraph on the drain body the floor drain, this distance the axial distance between the standpipe and top wall of the bell corresponds. Once the spacer is soft will reduce both distances down to zero, so that a double seal is given.

The idea of the invention also includes a floor drain, in particular for installation in floor slabs and preferably in conjunction with one of the preceding features, wherein means are provided for closing the floor drain or for changing the distance between the floor drain closing parts, and wherein these means are resilient under heat, in particular at less than 100 ° C. Preference is given to a soaking of the agent on contact with highly heated water or by steam. Due to the softening, the said compliant means can close the floor drain immediately or be effective as an aid. In this case, the non-softened means act, for example, as spacers between parts of the floor drain, which close the floor drain at softening agents, wherein the closing effect, for example, comes from a weight, a pressure or a spring force.

Further Features of the invention will become apparent from the description of the remainder and from the claims. embodiments The invention will be explained in more detail with reference to drawings. It demonstrate:

1 an exploded view of all parts of a floor drain or related parts,

This in 2 based on a water level 20 shown water runs from the outside under the bell 13 and passes through an annular gap 21 between a bottom edge 22 the bell 13 and an upper edge 23 of the standpipe 17 from above into the standpipe. The water level 20 results from the height of the upper edge 23 ,

So the bell 13 not with its upper wall 24 the standpipe 17 closes, rejects the bell 13 in the already used execution of a floor drain in the area of the lower edge 22 Brackets on which allow a distance of the lower edge 22 to a paragraph 25 on the drain body 19 will be produced. The brackets are not shown in the figures and at the same time the position of the bell 13 on the standpipe 17 Center.

The floor drain according to the invention 10 points between standpipe 17 and bell 13 between the top edge 23 and the upper wall 24 or an underside of the same, the spacer 14 on. This is star-shaped with three arms 26 and a round center piece 27 , The poor 26 have equal distances to each other. The middle piece 27 is with a central hole 28 provided and sits with the same on a pen 29 at the bottom of the upper wall 24 , drilling 28 and pen 29 are dimensioned and formed so that the spacer 14 inside the bell 13 is held. Optionally, locking means or fastening means may be provided.

The poor 26 are at their free ends with downward notches 30 provided on the circumferential upper edge 23 rest. Here is the spacer 14 arched, so that the middle part 27 on the upper wall 24 the bell rests and the arms 26 arcuate slightly downwards until it touches the standpipe 17 ,

The spacer 14 is made of a material that becomes yielding when heat is applied. Preferred is a softening temperature of 80 to 100 ° C. Deviations are possible. If in a fire in the standpipe 17 standing water is strongly heated, the spacer loses 14 Stability due to its heat-resistant material. The bell sinks 13 on the standpipe 17 until the upper wall 24 on the upper edge 23 rests and so the standpipe 17 closes.

The axial dimension of the spacer and the axial dimension of the bell 13 and the arrangement of the standpipe 17 in a lower narrow tube 31 of the drain body 19 are chosen so that the distance between the top edge 23 and the upper wall 24 with the distance between the bottom edge 22 and the paragraph 25 essentially coincides. As a result, the bell not only closes the standpipe in case of fire 17 but also in the area of paragraph 25 ,

The bell 13 is designed to improve the sealing function particularly heavy, preferably with a mass of one kilogram and more. Made the bell 13 especially made of stainless steel and with a machined underside of the upper wall 24 to improve the sealing effect described.

Paragraph 25 turns out to be a radially directed transition between the narrower tube 31 and one up at the heel 25 subsequent wider pipe 32 ,
