Description

Floor drain with foam block

Technical field

The present invention relates to it is a kind of for exporting to waste pipe from the ground Jiang Shui that can be passed through in floor drain, such as drenching The floor drain of bath equipment.

Background technology

Generally, what the water for occurring in shower was collected by discharger and and then stood relative to the people for taking a shower Ground continues guiding downwards.Discharger is referred to as floor drain below.The discharger is not required to be forced herein Property be arranged in the ground region stood of people of shower, but ground region side can also be for example arranged on, with the ground Region is adjacently built into wall, otherwise referred to as wall leakage.When in water on the wall drainage arrangement downwards rather than laterally leading When going out, drainage arrangement can also regard floor drain as here on this wall.

Additionally, the floor drain in following meaning should be discussed here, i.e. be to derive water from the ground that can be passed through, that is example If not being to derive water from wash basin or kitchen sink.The ground that can be passed through includes that fountain or Shower treadle are considered as what can be passed through Ground；The bottom of bathtub is not the ground that can be passed through.

Floor drain is exactly for a long time known and wide variety of.These floor drains are acted as in " point-like " Floor drain, this floor drain includes the horizontal zone with finite size, is wherein typically provided with around ground and directs water towards floor drain Inclined-plane.Common also has so-called slot type drainage arrangement, and this slot type drainage arrangement is along a horizontal direction ratio edge and the water Square prolong to vertical direction and to project farther, and water is collected by groove.

For the present invention, the design that water flows into the region of drainage arrangement on ground is unimportant.Term " floor drain " or " draining Device " even only relates to the element below such as groove of groove drainage arrangement here, and these elements for example set depending on concrete condition There are groove or other parts flowed into for water

Floor drain is installed in ground between floors, wherein below part interested be located at floor surface level it Under.As a rule, floor drain is directly integrated in the material of jointless floor.Particularly there is vertical inflow region and be connected to The pipeline of the elbow region of level thereon in jointless floor, for example receive from groove draining by the inflow region The water of the groove of device and by its downward guiding.What is be previously mentioned that is that may be present for making what water collected to drainage arrangement During slope is built into the jointless floor when jointless floor is laid.Alternatively it is known that the so-called plate being made of a foam material Part, this plate can accommodate floor drain and substitute jointless floor in the region of shower position.The plate can be laid on hair On the base ground and surface of the plate provides desired ramp structure；Plate correspondingly must add below when needed Lining.

The content of the invention

It is an object of the present invention to the integrated aspect in floor drain in earth construction provides a kind of favourable solution.

In order to realize the purpose, a kind of drainage arrangement for deriving water from the ground that can be passed through, the row are set Water installations have：Pipeline, the pipeline extends to horizontal ell region from vertical inflow region；Foam block, for accommodating The pipeline with inflow region and ell region, it is characterised in that foam block is in an ell region perpendicular to level Horizontal direction on be limited on the overall width for being 300mm to the maximum.

That is, the present invention relates to the installation of the drainage arrangement in foam block with least one duct section, the pipe Road section has the ell region of vertical inflow region and level.Other floor drain parts can with but be not required must set, example Such as it is arranged on the inflow funnel and/or blowoff basin and/or groove of inflow region upstream.Installation in foam block allows to reality The good combination of existing following aspect：The pipeline of drainage arrangement is simply for example maintained on blank ground, pipeline is protected And pipeline is integrated in jointless floor.Different from first known plate, foam block of the invention should be integrated in and set Put in the jointless floor in shower bath region (or other application environment of floor drain) and do not substitute jointless floor.Accordingly Situation be applied to other ground attachment elements.

Therefore, foam block at least (connects in the Longitudinal extending perpendicular to pipeline in the ell region of level and possible other It is connected in the conduit region on ell region) it is substantially narrower than plate on the direction in direction.The upper limit is 300mm, preferably 250mm, 200mm, 175mm are even only 150mm.In a specific embodiment, this value is 130mm.Lower limit certainly floor drain (not including foam block) width of itself.

That is, jointless floor (or other earth constructions) is laterally provided with beside foam block, so that foam block is not Predefine shower bath position or other around drainage arrangement space basic geometry.Particularly preferably installing completely In the state of, also above foam block set jointless floor (or other alternative earth constructions), that is foam block be not across Connect whole interior thickness between blank ground and floor covering, such as ceramic tile.But this is desirable in sheet material, because as above As confirmation, sheet material is also used for the gradient of prespecified corresponding shower floor.

Thus, the present invention is allowed advantageously and has protecting field that pipeline is anchored in ground, without thus causing on ground The limitation in the design on periphery is leaked, particularly because the prespecified height of sheet material (and gradient) and horizontal expandable aspect cause Limitation.

Additionally, foam block can be configured to so that foam block substantially surrounded by pipeline and therefore ensuring that realize it is good every Sound is protected.That is, abutted directly against at the position of pipeline in jointless floor, flowing occurs in drainage arrangement according to the present invention The strong introducing of noise, the hydrodynamic noise can be eliminated by foam block.

Smell envelope is generally provided with the duct, and the smell envelope works according to siphon principle.The smell envelope can pass through Wall portion that is being sunk to inside inflow region and being not entirely to bottom constitutes or can also partly from inflow region Stretch out, that is, the ell region of level is a part for siphon pipe.All be preferably in each case, siphon pipe or All siphon pipe levels are all in foam block in the case of multistage siphon pipe.Because the flow path of water is curved and meeting There is water-air mixing, so noise can be sent in general siphon pipe.

On the other hand, due to the Longitudinal extending perpendicular to pipeline in above for horizontal direction direction explanation already The reason for, the compact structure of foam block be it is favourable (that is, in order to individually and not have in the outside of foam block Geometry limitation ground manufacture earth construction).In this sense, foam block overall elongation length in this direction is up to 400mm. It is also preferred that the following upper limit：375mm, 350mm or even 325mm.Embodiment has the value of 300mm here.At least When smell envelope siphon pipe is set, preferred lower limit is in 200mm or so.

Foam block is essentially one, can particularly surround pipeline and foam to be formed., but it is preferred that at least two parts Design.One possible advantage (except the advantage that other are illustrated below) is, even if foam block is (in the shape of assembling Under state) surround pipeline in itself, the pipeline still has the property of can be taken off.Situation described above is preferred, reliably to keep Pipeline simultaneously ensures good sound insulation protection.But due to this manifold configuration, therefore also retains separability.

Another possible advantage of many part configurations is that it is possible in a straightforward manner enter different (foam) shells The different optimization of row.Especially as the setting of preferred form of implementation, lower shell and top casing element are provided with, lower shell is from following support Pipeline simultaneously makes it be carried on blank ground, and top casing element covers pipeline and supports pipeline at least in part upwards.In such case Under, lower shell is made up of the foamed material softer than top casing element, so as to realize optimal sound insulation between pipeline and blank ground Protection and can realize improved anti-trampling intensity between pipeline and floor covering.

In addition each shells can be encoded by different colors, so that installation personnel very well and can be closed rapidly Information where should be partly installed in which.For example lower shell can be light gray or white, and top casing element can be grey Or Dark grey, due to blank ground on step puigging and color similarity with the color of jointless floor, this is right It is directly perceived and obvious for installation personnel.

Another advantage of foam block of the invention may is that, (particularly can be integrated with siphon with " floating " During pipe) or simplify pipeline geometry complex in itself.Particularly, foam block can have simple in a horizontal plane Rectangle elementary contour and other relatively simple and rough structures can also be configured to.This is for example easy to pour seamlessly Face simultaneously causes the cavity for being easy to avoid occurring unintentionally.This also cause with the combination of other surface structures materials and with step every The combination of sound and provision for thermal insulation is more easy.

One favourable form of implementation is, at least two adjacent corners of rectangular base outline with predetermined separation unit The form of position sets the corner that can be separate, particularly for setting up 45 ° of seamed edges of chamfered edge shape.Thus, foam block can need When at an angle, particularly 45 ° are moved to very close to other regions, such as vertical wall.Particularly when elongated Vicinity on the corner of the elementary contour of rectangle in the narrow side of the upside of foam block is provided with the opening of the inflow region for pipeline When and when part (the i.e. ell region or in downstream that drainage arrangement side for pipeline is provided with the end face on opposite narrow side The part that position is connected thereto) opening when, it is particularly the case.

In principle, when foam block is in-site installation, foam block is not required to be fixed in itself, because foam block is usual Fixation is realized by the connection of pipeline and other pipeline members.But independent fixed part is preferred.For example it is contemplated that It is bonded on infrastructure.While being not excluded for bonding alternatively, can set continuous for fixing in foam block The opening of bolt, particularly vertical opening.The opening can be by sleeve, such as in the press-in foamed material being made of plastics Sleeve obtain stabilization.This shows in embodiment.

Another preferred embodiment is provided with clamp, and the clamp keeps together at least two shells.Clamp example Can such as have substantially U-shaped section bar, e.g. be made of metal or fiber strengthened plastics are made, and with a leg Acted on lower shell from below, and acted in top casing element from above with another leg.For the ease of it is smooth and without incline branch Hold in base foundation, in acting on the recess during the leg on lower shell can be embedded in lower shell from below here, so that it is not Must insert between the shells and following bottom, see embodiment.It is that upper leg can be configured to special large area and for example cover At least the 75% of the area in the highest level of top casing element of top casing element, and thus improve and anti-trample intensity.Top casing element it is whole If individual upside is not required so to do --- miscellaneous part sinks and therefore for anti-intensity of trampling does not play main work With (such as because the jointless floor thickness above it is a lot).Additionally, when the uppermost region of upper component passes through clamp leg It is such as lattice-shaped or other be provided with the structure in opening or gap and when obtaining stablizing, the area of the highest zone of upper component Also it is sufficient that.Fine structure below the common-size of this 20mm to 30mm --- to trample intensity inessential for anti-for it --- it is not counted in the quantitative measurement of covering part.

Additionally, clamp can have laterally projecting part, the part can be connected to jointless floor or other ground In construction material and thereby assist in and realize grappling.This will also be described in detail according to embodiment.For example it is considered as along level side To bending and/or prominent part.

In the grappling in considering (such as) jointless floor, to consider that jointless floor can shrink in drying and hardening.It is logical Certain elasticity substantially is crossed, foam block of the invention is in this respect favourable.Additionally it may be advantageous that pipeline Transition part in the vertical direction between inflow region and ell region be designed to it is somewhat resilient, for example by elasticity ripple Line tubular construction.When the drainage arrangement part for for example being connected in the upstream of inflow region, for example, funnel or drainage groove are flowed into, itself It is connected in jointless floor and only simple (or being attached in the inflow region of pipeline) attached thereto well, then passes through Shrink and cause vertical power to act on, the power for example may act on the bellows structure.

Finally, already here it should be pointed out that, foam block is preferably covered by jointless flooring when mounted, that is, be not as passing The plate of system extends to ceramic tile bond like that.

Specific embodiment

Fig. 1 shows the perspective view of drainage arrangement of the invention.Here the foam being made up of two parts is represented with 1 Block, described two parts are bottom and top, and so-called bottom is lower shell 2, and so-called top is top casing element 3, the two portions Divide and shown with separate state in Figure 5.Foam block 1 have rectangle elementary contour shape (viewed from above in Fig. 1) and And the end face of the sensing right front of foam block from Fig. 1 of waste water pipe joint 4 is protruded.On the opposite side of rectangular base outline Project upwards receiving pipe 5, the receiving pipe upper end terminates at visible flat peviform flange 6 in Fig. 2, placed on flange have compared with The lid 7 of circular collar 8 wide.

Lid 7 covers a sealing gasket being moulded on flange 6, and the sealing gasket is foldedly located at below lid, collar 8 Limit the height level of the upside of subsequent jointless floor.Therefore, figure 1 illustrates integrally-built downside be placed on blank ground Fixed on face and in the form of it will be illustrated that below herein, and pipe 5 is accommodated come certainly by being truncated on the lower end for accommodating pipe 5 Highly, the receiving pipe is inserted in inflow region 9 according to Fig. 2 for fixed desired jointless floor.The inflow region slightly expands upwards Exhibition, to accommodate seal profile 10 (Fig. 2), the seal profile is kept using the retainer ring 11 of buckle-type.Thus, pipe is being accommodated Sensing under insertion end be positioned on correct height after, by retainer ring 11 also can fix accommodate pipe 5 position Put.

Accommodate why pipe 5 is referred to as accommodating pipe, because setting up jointless floor and setting up in lid 7 sealing After the connection of the composite seal on the upside of pad and covering jointless floor originally, can will such as trench drain device from above The insertion of inflow funnel accommodate pipe 5, that is, the inflow funnel with accommodate pipe 5 identical mode itself and have downwards The insertion end (but with less diameter) of sensing.These details only belong to the content of secondary concern for the present invention；With reference to Fig. 1 and Fig. 2 may further determine that, under completion status, jointless floor extends to the plane of collar 8 and by all under it The part embedment (each accompanying drawing shows to accommodate the height do not truncate and thus particularly pertinent of pipe 5) in face.Additionally, drainage arrangement The top that collar 8 is arranged on for the visible part of user.The last part shown in Fig. 3 to Fig. 6 is not (including element 5 to 8,10 and the drainage arrangement that 11) is also regarded as in each claim meaning.

As the decomposition view in Fig. 4 especially clearly shows, lower shell 2 and top casing element 3 are shape-ordinatedly surrounded From inflow region 9 until the duct section of the waste water pipe joint 4 in downstream.Therefore, the pipeline can be placed into lower shell 2, See Fig. 4, then, first insert below retainer ring 11 top casing element 3, its opposite end is reduced and thus overall real Now it is set with, sees Fig. 6.Fig. 3 shows assembled state, wherein showing for convenience, saves the half portion to left front orientation of top casing element 3. In addition Fig. 2 also helps reference, wherein, lower shell 2 and top casing element 3 are shown with different hacures.Elementary contour rectangle has The size of 300mm × 130mm, only need to be slightly larger than pipeline.

Here, pipeline is generally close to S-shaped.From the inflow region 9s with vertical main flow direction, under it Face connects to the right more prominent bending section in the horizontal direction in fig. 2, and thus pipeline is in the position being vertically aligned with receiving pipe 5 In extend laterally.Here, this is referred to as ell region 12.From ell region 12s, pipeline is raised by common siphon arrangement To a height level, in this height level, the lower edge of pipeline substantially reaches the height level of the top edge of retainer ring 11. In this peak regions 13, pipeline have the bending section in opposite direction relative to ell region 12 and therefore from peak regions to Downstream declines.Therefore, in peak regions 13, the bottom of cross-section of pipeline limits the water seal height of siphon pipe, wherein, water seal exists Inflow side approximately reaches the top edge of retainer ring 11.

In pipeline section in ell region 12 and peak regions 13 and between them, pipeline has wider and more flat Cross section, sees Fig. 4, the cross section peak regions 13 downstream then continuously narrow and uprise, so as to thus substantially from Common circular cross section with drainpipe before opening the outlet of foam block 1.Therefore, foregoing drainage arrangement side is useless End face of the water pipe head 4 circularly from foam block 1 stretches out.

Fig. 2 shows this relation, and the right lower quadrant region and its right for accommodating pipe 5 are shown with longitudinal sectional view, namely in The structure through Fig. 1 is entreated, its left side and top are illustrated with side-looking, wherein, the transition part between each several part is illustrated with meander line Property is represented.Also with such zigzag, with cuing open for being biased relative to remaining longitudinal profile in the lower right area of Fig. 2 Face shows a small part, such as explained below.Fig. 3 to Fig. 6 is illustrated with oblique vertical view pressed from inside respectively Enter the upside of the plastic sleeve 14 in the lower shell 2 of foam block 1, the plastic sleeve has substantially T-shaped longitudinal profile.Fig. 2 The longitudinal profile and free space thereon are shown, for (unshowned) fixing bolt, foam form are being placed according to Fig. 6 Before top casing element 3, the lower shell 2 of foam form can be first screwed on the ground using the fixing bolt.Fig. 2 is also The tortuous structure of shark's fin shape on the periphery of sleeve 14 is shown, sleeve 14 is maintained in the lower shell 2 of foam form using the structure.

In addition Fig. 3 to Fig. 5 shows that the interior shape of the lower shell 2 of foam form is mutually fitted with having deviation with the shape of pipeline Match somebody with somebody；This is applied equally to the interior shape of the top casing element 3 of foam form.Two foam shells are particularly jointly complete encirclement Pipeline, in addition to following：Be first pipeline in itself by mouth；Followed by the region below ell region 12, in the region In, in order to be conducive to generally flat planform and smaller in view of the wall thickness for leaving, there is breach；And be finally The breach reserved for similar reasons above peak regions, the two breach show in figures 4 and 5.Here, pipeline is relative Bounced back slightly inward in the corresponding external reference face of foam block 1, so as not to sound are directly delivered into blank via foam block 1 On ground or jointless floor.

The lower shell 2 and top casing element 3 of foam form are kept together by metal clamp 15, see Fig. 1 to Fig. 4, the gold Category clamp substantially has the U-shape of 90 ° of upset on the direction of observation in Fig. 2.Downside leg here according to Fig. 4 includes two Thus individual single shelf 16, remain in corresponding recess and in the lower surface of the lower shell 2 of the two shelves insertion foam form With the interval on ground.Thus, even if the lower shell 2 of foam form is already fixed to when on ground, clamp 15 can also be inserted.On Side leg 17 be large area and almost covering foam form top casing element 3 whole uppermost part, can mutually comparatively Referring to Fig. 1 and Fig. 3 in Fig. 4 and Fig. 5.

Here, metal clamp 15 is configured to strong so that wall thickness is not the top casing element 3 of very big foam form sometimes Stabilized, load is trampled with anti-, in the case that jointless floor particularly thereon is relatively thin.Along the watcher according to Fig. 2 To or opposite to that direction, the bent angle section 18 of L-shaped is stretched out from upside leg 17 respectively, the bent angle section has horizontally outward Prominent lath and the clamping shelf 19 in vertical side leg.Metal clamp 15 is locked in foam form by clamping shelf 19 Top casing element 3 recess in, see Fig. 4 and Fig. 1.By clamp 15 and thus the side leg 18 of level is used to also having that Fig. 1's to be whole Structure is connected in jointless floor.Additionally, in being provided for being connected to jointless floor in the region of described flange 6 Structure.

If jointless floor is shunk in drying and solidification, certain residual elasticity of foam block 1 and clamp 15 absorbs Corresponding tolerance, without the damage or the formation in crack that cause pipeline occur.Additionally, be able to will be accommodated when vertical force is larger Pipe 5 is in seal 10 gently towards pushing.Additionally or for safety reasons (for example accommodating the insertion end of pipe 5 In the case of being located below), resilient bellows knot is set in the transition part between the inflow region 9 of pipeline and ell region 12 Structure 20, as Fig. 2 section views are illustrated, and it is visible in figs. 3 and 4 in addition as.

Last Fig. 1, Fig. 4 to Fig. 6 show, the part of foam block 1 be designed to by predetermining fracture position it is separable, just It is to say, two corners adjacent with inflow region 9 are separable.Predetermining fracture position is represented with 21 and can be in phase here 45 ° of seamed edges of chamfered edge formula are realized on the corner answered, due to the seamed edge, foam block 1 and thus also have figure 1 illustrates it is whole Structure can also close proximity be moved with above-mentioned angle to for example vertical wall.Here will it is considered that flange 6 and lid 7, It is in fig. 2 rotatable including collar 8, and the part for protruding from flange 6 of collar 8 again may be by predetermined fracture Position disconnects.In Fig. 1, predetermining fracture position shows in the left end of collar 8, and Fig. 1 collars 8 the left back part energy of sensing It is enough to disconnect.

Because these accompanying drawings are lines figure, therefore it is not shown, the lower shell 2 of foam form is designed to white or very shallow Grey, and upper foam shells is designed to Dark grey, so that as described above, these foam shells can be in case obscure ground Directly it is mutually matched.Here the lower shell 2 of foam form is softer than the top casing element 3 of foam form and thus ensure that relative to blank The particularly preferred sound insulation in ground and side, and upper foam shells optimized in intensity in anti-being trampled.
