Description

Heat exchange system

It relates to convectors for heating or cooling systems, which are installed in shafts, ducts, cavities, on walls, ceilings and floors, etc. In particular, it relates to mounts and fastenings from and to convectors and from their covers.

Convectors are heat exchangers made of pipes with fins, which are installed in single-pipe to multi-pipe versions, side by side and / or one above the other in wall or floor recesses or special cladding. Finned tubes are also used in the heating technology. The fins enlarge the heat-exchanging surface. If convectors are used as radiators, the air enters below the convector, heats up and exits the room through openings.

From WO 98/13651, a mounting device for heat exchangers and their cladding is known, which comprises a U-shaped support which both receives the heat exchanger and carries the cladding on the U-shaped upwardly projecting legs. The carrier can be picked up by a rail on its underside and held laterally displaceably in the rail.

In many cases, it is also necessary to place or attach or fasten lattice frames on troughs or shafts etc. for floor convectors and for other purposes and at the same time form a larger contact surface and / or at least one wall anchor on each side of the lattice frame and stiffen the To reach the grid frame.

The present invention has for its object to provide heat exchangers with brackets and with fastenings for their cover so that a) a largely uniform air circulation around the heat exchange elements is granted, b) the heat exchangers at small or larger distances from support surfaces such as floor, brackets, holding parts etc., are to be held and positioned with a certain freedom of movement in the longitudinal direction as well as in the transverse direction of the heat exchanger; c) if necessary, an air guide plate on one or both sides of the heat exchanger in various positions and preferably at different depths / heights in all necessary lengths can be attached; d) heat exchangers can be arranged one above the other, provided that they are not already formed one above the other; e) the grille covers of convectors mounted in trough-shaped recesses can be fastened to the walls or in the masonry with simple means.

All of these requirements are met by this invention in that both the attachable or clampable support parts on the heat exchange elements, which on the one hand keep the heat exchange elements at a distance from the support surfaces or walls or one below the other, enable the attachment of air baffle plates and / or bypass lines to the heat exchange elements, as well as new fastenings for the grille cover of the convectors are provided, wherein grille covers are also to be understood in the context of the invention.

Claim 1 indicates essential elements of the invention. Further features and designs according to the invention are set out in the remaining claims.

An advantage of the invention is that the individual support parts or fastening arrangements can be used together or separately and are compatible with one another. Thus, with several relatively small parts, heat exchangers in many variants and combinations of the same with different installation systems, heights, depths, lengths and also different claddings, covers, grid frame designs and air grilles can also be used individually, independently or in combination.

The support parts can be placed on the heat exchange elements in that they have insertion parts which can be inserted between the fins of the heat exchange elements and each provide at least one groove, each of which receives a tube of a heat exchange element. In further embodiments, the support part is preferably held by hooks or a clamp. Hook can also denote a straight part, which can be resilient or has a clamp. A groove can comprise two hooks, one or both hooks being clamped or at least one clamp being arranged between the hooks on the groove. Alternatively, a clamp or a ken be rigid and the clamping is carried out by a one-sided resilient clamping or a hook. The groove can be designed in such a way that heat exchangers with other pipe positions or pipe diameters can also be supplied with the same support part, the pipe not having to rest in the groove or free spaces between the pipe and groove or hook or clamp can remain open.

The insertion parts or hooks can have grooves, extensions, grooves, sliding parts, latching options, which cooperate with measures of the slats of the same type.

Through these support parts there is only a minimal support surface between the pipe support part, so that there is sufficient space for air to flow around the pipe. In order to obstruct air convection as little as possible, the components can also be designed in a streamlined manner or equipped with convection openings, insert parts, extension arms, sliding bands and sliding frames of the support parts and their extension parts being particularly suitable for this purpose.

In preferred embodiments, projecting cantilevers can be attached to the push-in parts, which lie on the outside of at least one, preferably several, lamellae and both bring about additional stabilization of the supporting parts and small differences in dimensions between the heat exchanger and supporting part can be compensated for by the cantilever is pressed against the slats. The heat exchanger is thus held or clamped by the hook or clamp, possibly on both sides of the tube, and rests with its fins on the brackets.

In addition, it is possible to mount air baffle plates and / or bypass lines etc. directly above / next to a heat exchanger with such support parts.

The various lattice frame designs can be connected to a guide wall using a mounting block or anchored in the masonry. The height of the lattice frame can optionally be adjustable and, in a special embodiment, have a cladding on the outer sides which can also be formed from the tub or a tub side part, etc., so that the lattice frame can also be adjusted after completion (concreting, etc.) . In all possible designs of heating and / or cooling systems - convectors etc. in connection with air baffle plates, a natural and or artificial air circulation can be carried out. For example, air ducts laterally assigned to the convectors or their duct covers can also cooperate with cross-flow blower covers or cladding for this purpose with modified air guide plates. Air ducts or duct covers that can also be used in the open part in the troughs of floor convectors can cooperate with air baffle plates also in combination with fresh air supply, air from heat recovery, air from solar collectors, etc.

In the designs according to the invention, heat exchangers in single-pipe to multi-pipe designs can also be used one above the other, positioned next to one another. The same applies to all duct, tub and shaft designs, even if the duct has air guiding plates on one or both sides for natural or artificial convection.

FIG. 1A shows a section through a heat exchanger 8 with a tube 1 for liquid media or electrical operation consisting of a tube 1, preferably made of metal, which is arranged thereon at spaced fins 13. An air baffle plate 6 is arranged on the left side.

1B shows a section through a heat exchanger 8 with two tubes 1 positioned horizontally. Fig. IC shows a heat exchanger 8 with three tubes 1; Fig. 1D one with four tubes 1, wherein more than 4 tubes can also be arranged.

1E shows four individual heat exchangers 8, each with a tube 1 horizontally next to one another, with alternatively more or fewer heat exchangers 8 being able to be arranged; Fig. IF a heat exchanger 8 with two tubes 1, shown vertically, alternatively more tubes can be provided and Fig. IG two individual heat exchangers 8 with a tube 1 but one above the other at a small distance from each other, also - not shown - obliquely or Heat exchangers 8 arranged at different angles are possible, and combinations of all the types shown / described next to and or above one another are also possible.

Fig. 1H shows a heat exchanger 8 shown obliquely from the front, an air guide plate 6 is positioned backwards.

FIG. 2 shows a cross section through a heat exchanger 8 according to FIG. IB. This heat exchanger 8 is positioned in a trough installed in the floor (floor convector) at a distance from the support surface of the trough. An air grille, roller grille, etc. is not shown. An air guide plate 6 is positioned to the left of the heat exchanger 8, and there is enough space left in the trough to repair convection under the air guide plate 6 via the heat exchanger 8. In order not to increase the height of the trough and yet achieve the necessary convection efficiency, the air guide plate 6 is not as high as the fins 13 of the heat exchanger 8. In addition to the heat exchanger 8, in the area of the tub or another wall or also free-standing, an air duct 27 is assigned. A tab 28, for example, which is attached continuously or at intervals, inserted therein with its preferably continuous legs 31, a channel cover 29, which can have different shapes. In this case, the channel cover 29 has a bevel 30 downwards in the direction of the heat exchanger 8. In another embodiment, the channel cover 29 is designed to be adjustable in height, and channel covers, which may be closable, may have openings, slots, etc. In the case of repairs or cleaning work, such duct covers 29 are easy to remove and reinsert.

In another embodiment, the channel cover 29 has a lower part (not shown), which rests on a support surface (floor), but it is necessary to fasten this channel cover here, which is not necessary when using the tab 28 leg 31 connection. An easily removable duct cover 29 is also necessary for the use of electrical heating elements which, if required, are accommodated in the longitudinal direction of the air duct 27.

The air duct 27 has at least in the direction of the heat exchanger 8 a through opening for the air flow L indicated by the arrow and cooperates with the air guide plate 6, the air guide plate 6 and the duct cover 29 having different, mutually coordinated shapes or air guide measures.

Fig. 3 shows another floor convector as in Fig. 2, but here the trough is formed higher and there are two heat exchangers 8, each with two pipes 1 arranged one above the other. Air guide plates 6 are positioned on both sides, which in this illustration extend as deep as the lower heat exchanger 8 or its fins 13 (lower edge) and higher than the upper heat exchanger 8. In another embodiment, the lower and upper heat exchanger 8 can be connected to one another.

In FIG. 4, a heat exchanger 8 according to FIG. IF is positioned next to a wall and held behind a cladding 17, an air baffle 6 is attached between the heat exchanger 8 and the front cladding 17. With such or similar designs, heat exchanger 8 held by consoles, holding parts, etc. A front cladding 17 is also possible on both sides of a wide variety of heat exchangers 8.

5A shows in cross section a heat exchanger 8, a tube 1, the lamella 13 with dashed lines. This heat exchanger 8 is kept at a distance from a support surface, by a support part 11, this is used in a heat exchanger with only one tube 1 and also in heat exchanger 8 with two or more tubes 1, with two tubes 1, the support parts 11 are used on both sides, in the case of more than two tubes, at least on both sides, even in the case of heat exchangers 8 one above the other according to FIGS. 1 F + G and 3, etc., these support parts 11 are to be used. The support part 11 consists of an insertion part 2 which has hooks 7 on both sides (extensions, terminal strip, etc.), which can also be designed to be resilient or adjustable, the shape of these hooks 7 being different. The height of the hooks 7 can also be made higher, from a trough formation to a clamp 9 and beyond. For reasons of stabilization, the insertion part 2 and or at least the hooks 7 and or the clamp 9 can also be formed higher, also from the center of the tube 1. The insertion part 2 is preferably at least 30% as wide as a single-tube heat exchanger 8 or a part of the heat exchanger 8 with a tube, at least on the lower base (end of the heat exchanger 8 or its lamella 13). The insertion part 2 can also have open or closed openings. The lower part of the support part 11 consists of at least one foot 12, the height of the foot 12 being at least 5% of the height of the heat exchanger 8. The foot 12 can also have knobs 12a in order to increase the sliding ability. On both sides inside and or outside the feet 12 have sliding edges 12b, which are described below in FIG. 6. Preferably, on both sides of the support part 11, at least one bracket 3a is formed, only one bracket 3a is formed in the necessary width, this preferably has convection openings, ventilation slots, etc. These brackets 3a can have a wide variety of shapes, the brackets 3a of this illustration hinder convection in the region of the support part 11 only very slightly. In yet another embodiment, the boom 3a can also be formed on both sides of a support part 11 in the lower region of the heat exchanger 8 and thus prevent the heat exchanger from tipping over. This version is only to be used for heat exchangers 8 with a pipe. Fig. 5B shows a support part 11 with its insertion part 2 and hook 7 inserted between slats 13 in cross section. The tube 1 is positioned between the hooks 7. The one or more feet 12 lie on a support surface. The boom (s) 3a are either formed only on one side of the support part 11 or preferably on both sides.

Fig. 5C shows the position of the boom 3 a, preferably on both sides of the tube 1 and on both sides of the insertion part 2, seen from above. In the case of heat exchanger 8 with more than one tube 1, the support parts 11 can also be used independently of one another at different points in the course of the heat exchanger, also offset from one another. The brackets 3a can also be mounted laterally, vertically of a one-pipe heat exchanger 8 and can also be made very narrow. Support parts 11 with brackets 3a on both sides, which can also be designed as a holder for air guide plates 6, can also be used for round, oval, etc. single-tube heat exchangers 8. In yet another embodiment, the groove 10 can be made deeper or the hook 7 higher so that heat exchangers 8 can also be supplied with different dimensions, the holding is then carried out mainly by straight hooks 7 on the inside (or slight bulges, clamps 9, etc., in the pipe positions) since there must be a limitation in different heights / depths of the pipe 1. (see also on Fig. 12,13)

FIG. 6A shows a heat exchanger according to FIG. 2. A heat exchanger 8 is shown above the tub 47, a sliding frame 21 is arranged on the bottom of a tub, this is factory-fitted, but can also be installed, glued, screwed, etc. on site. Two support parts 11 are positioned in the slide frame 21, these support parts 11 are preferably previously clipped, clamped or pushed onto the heat exchanger 8 below and can also be held only by the fins 13. The heat exchanger 8 is then placed with the support parts 11 on at least one sliding frame 21. The sliding frame 21 includes stop delimitations 23. Via this stop delimitation, at least one flat sliding band 22 is attached, which at least in the case of a support part 11 prevents it from being moved sideways by resting on at least one sliding edge 12b of a support part 11, preferably the sliding band 22 is positioned between feet 12, thus only one sliding band 22 is sufficient for heat exchangers 8 also with several tubes next to one another. In the case of heat exchangers 8, each with a tube attached next to one another, a sliding band is to be attached to each support part 11 and heat exchanger 8; in another particular embodiment, at least one sliding band 22 is arranged, as the illustration also shows as a loop, etc. The sliding band 22 has smooth, preferably thin, sides Sliding edges 12b ', which allow the support parts 11 with feet 12 to be provided with sliding edges 12b lengthways can be pushed or allow for thermal expansion. In order to allow a very good upward air flow also over the sliding band 22, convection openings 16 are provided on the sliding band 22. The sliding band 22 can be attached in short pieces or continuously and is connected with extension parts 24 'to the floor and / or fastening parts 25' or a sliding frame 21 etc. In special embodiments, the sliding band 22 can also be attached coming from a wall. The extension parts can have all possible shapes: webs / strips, columns, etc. The fastening parts 25 'can have all shapes. The sliding band 22 can also be narrow, thin, etc., for example also made of wire, strand, rods, etc., and can also be attached in pairs, etc.

A sliding band 22 with at least one extension part 24 'and possibly also a fastening part 25' in a corresponding embodiment can also be guided or held adjustably in a longitudinal guide (groove and / or extension) by a support surface (also holding part or trough), optionally also a Plugging, sliding, snapping, etc. possible. The recess 3, which is preferably arranged between the feet 12 on both sides, is somewhat wider than the width of the sliding band 22, but can be adapted very narrowly / thinly if very narrow sliding bands or also impact limiters 23 or other extensions are used. In special designs, more than one recess 3 can also be made on a support part 11, and guidance on both sides of the support part 11 or a foot 12 is also possible.

FIG. 6B shows a cross section through a floor convector positioned as in FIG. 6A. The sliding band 22 is arranged approximately in the middle from the contact surface to the fins 13 by the extension 3a and does not hinder the ventilation of the heat exchanger 8 either transversely or lengthwise. The stop limitation 23, if fitted, is also kept low and can also be interrupted, or be attached only in the area of a support part 11. The sliding frame 21 is as wide as it is necessary to be able to move the heat exchanger 8 during assembly and to allow expansion of the heat exchanger 8 as a result of the heat, for example a total of 100 mm. However, the slide frame 21 is preferably not deeper than the heat exchanger 8, in order to obtain a free channel on one side or, in other embodiments, also a free channel lying on both sides next to the heat exchanger 8, in order to also enable longitudinal ventilation and to carry out cleaning work without obstructions. There are therefore no overall foreclosures. In another embodiment, also in combination with at least one sliding band 22, the support part 11 can also be double, etc., that is to say designed for at least two pipes 1, brackets 3a can then be omitted. In another embodiment, the bracket 3a is omitted and the groove 10 is designed as a receptacle for the entire heat exchanger 8 (with fins, wire, etc.) and bracket 3a are attached to the side of the heat exchanger and can optionally have grooves 5 for the air guide plate 6 on one or both sides exhibit. The contact surface for the heat exchanger 8 is larger, deeper and the feet 12 are also formed in two rows, etc.

6C shows a heat exchanger 8 seen from the side. The sliding frame 21 consists of a support surface and a stop 23 at a distance from the lower support surface (bottom of the heat, etc.). The sliding band 22 is preferably attached to the stop delimiters 23, and a support part 11 with cantilevers 3a inserted between the slats 13 from below is positioned in the sliding frame 21. There is enough space in this to allow longitudinal displacements. The convection takes place from the front (air guide plate 6 not shown) or from both sides (FIG. 3) and is not hampered at all by the sliding frame 21, stop limitation 23 and sliding band 22. Slide frames 21 can also be used with other variants as well as with consoles, holding parts, etc.

7 shows a sliding frame 21 which is held by at least one extension part 24 at a distance from a support surface or a support part. The sliding frame 21 has at least one sliding band 22, optionally with at least one convection opening 16, even without a stop 23, and at least one longitudinal extension which is connected to the surface of the sliding frame, this extension preferably having at least one convection opening 16.

In yet another embodiment, the slide frame with its support surface and at least one slide belt or with a protruding edge that delimits the slide frame in the longitudinal direction is designed as a slide belt like a bracket for a wall fastening part. The sliding frame stands away from a wall and creates a desired distance from the floor or a support surface. The limiting slide band, which may be formed from the slide frame, brings about the necessary stability for such a design. The limiting edge protruding from the slide frame can also be used as an extension towards ten be formed and is only used for stability, and only at least one sliding band is attached above.

7, the heat exchanger 8 is brought into a higher position than the height of the feet 12 of the support part 11 allow (see FIG. 6). For this purpose, the sliding frame 21 is increased by extension parts 24 on one or both sides transversely to the heat exchanger 8, which preferably have fastening parts 25 with which they rest and can also be fastened. At least one convection opening 16 is preferably attached to the sliding frame, likewise to the extension parts 24. Instead of at least one extension part 24, for example made of sheet metal, various extension parts, spacers, supports, feet, columns, etc. can be used.

In another embodiment, at least one stop delimitation is arranged longitudinally to the heat exchanger and thus takes over the function of a sliding band (the stop delimitation preferably having at least one convection opening). Sliding frames are preferably open in the direction of convection, so that air can also pass over and under the sliding band or stop limitation, also supported by at least one convection opening in an embodiment with extension parts 24. Of course, a sliding frame 21 can also be designed without forming stop restrictions, a sliding band 22 is then connected to the extension parts 24 'or the support surface 25' to the sliding frame 21. Slide frames 21 with extension parts 24 can also be used for fixing or holding / guiding etc. of heat exchanger 8, for example when creating a fixed point.

8A, the cross section of a heat exchanger 8 is positioned at a distance from a support surface, on which pipe 1 is suspended between two fins 13 with a clamping hook 19, as in FIG. 8B. These clamping hooks 19 are hooked onto a heat exchanger 8 on both sides or on one side at intervals in order to be able to accommodate air guide plates 6. The clamping hook 19 consists of at least one insertion part 2 and at least one hook 7 and groove 10, and an extension arm 3a which has a side part 4 and thus forms a groove 5. A groove 5 can also be formed on both sides. The insertion part 2 is placed on the tube 1 with a hook 7, and a clamp 9 can be attached. The groove 10 is at such a distance from the arms 3a that there is a good fit, so that the arm 3a groove 5, side part 4 and then the used air baffle plate 6 coincides with the one or more vertical side fronts of the heat exchanger 8 or fins 13.

Fig. 9 shows a heat exchanger 8 seen from above with hooked or hooked or hooked-in or hooked-in hooks 19 and inserted air guide plates 6, wherein two air guide plates 6 are arranged in parallel in the area of the groove 5. The clamping hooks 19 are also used in multi-tube heat exchangers 8 on one or both sides, even in the case of heat exchangers 8 arranged side by side and one above the other, wherein the clamping hooks 19 can be inserted into a lower or upper, also into a centrally arranged, heat exchanger. In a special embodiment, a clamping hook can also have hooks on both sides, or at least one clamp. Air baffles 6 are formed in special designs as a U which is open at the bottom, one leg being in the groove 5 and the other leg having different shapes in order to direct or deflect air, to stop, etc. The part in the groove can also be short be, as well as the side part 4 can be short and adapted.

Fig. 10 shows a clamping hook 19, for example made of plastic as in Fig. 8, but with the difference that the side part 4 and the groove 5 are missing in this embodiment. Only the boom 3a is available. In this particular embodiment, an attachment part 19a with the side part 4 and the groove 5 is placed on the clamping hook 19 or at least one arm 3a, pushed, clamped, etc. (see above)

The attachment part 19a is, for example, loop-shaped, possibly in the form of a "lying S", made of sheet metal or plastic. A U open at the top forms a groove 5 for an air guide plate 6, a U open at the bottom forms a groove 5 'for sliding on the bracket 3a, the sheet-metal support surface 3b (also made of plastic, etc.) will at least partially rest on lamellae 13, a recess 3c may be provided, a slot for the insertion part 2 or the sheet-metal support surface is shorter, approximately up to the height of the insertion part 2. The set part 19a can be designed in such a way that a clamping part 3d clamps the air guide plate 6. The groove 5 for the air guide plate 6 is dimensioned such that two air guide plates 6 are to be used face to face in the joint or side by side, which is for reasons of Stability is advantageous In yet another embodiment, the attachment part 19a can also have a groove on the outside be allowed to sideways of the heat exchanger 8 to lead a tube. The attachment part 19a can be made of wire, sheet metal, metal, plastic, etc. and connections made of one or more parts.

11C shows a further heat exchanger 8, lamella 13 and tube 1 according to FIG. 10. In this particular embodiment, the extension 3a is shorter than the fins 13, for example 1/3 shorter, and is therefore also compatible with lateral extension 3a Support part 11 (see Fig. 5). An attachment part 19a is also shorter than the slats 13; this may be necessary, as described in FIGS. 1A and 2. The insertion part 2 has a slot 3c 'in order to be able to receive at least a continuous part of the sheet-metal support surface 3b if a snap-in device is dispensed with. The top part 19a of FIG. HD is deeper, to the lower edge of the heat exchanger 8 than in FIG. 11C and in FIG. 11E the top part 19a extends deeper than the fins 13 of the heat exchanger 8. The snap device 26 is always at the same height Depth as the lower edge of the bracket 3a of the clamping hook 19. This version of the clamping hook 19 or attachment part 19a can be used in different installation variants. Instead of a hook 7, two hooks 7 can also be formed horizontally with or without clamps 9 with connecting parts to the brackets 3a and the clamp hook 19 can also be snapped or pushed laterally onto the pipe 1. All insertion parts 2 in all figures can also be designed two or more times. In this case, the support surface 3b is assigned between the boom 3a and the slats 13; if necessary, the insert part can also have at least one boom at the top and be supported on the slats 13 at the top.

In Fig. HA, the boom 3a lies smooth on the slats 13 and adjacent to it, the insertion part 2 has a slot 3c 'at the top. The attachment part 19a, with its now shorter, continuous contact surface 3b, is inserted into this slot, both of which can also be designed as clamps or snaps. For example, at least one groove, extension opening, groove, etc. can be provided in the slot area on the insertion part 2 and a latching can take place by bulging out or bulging out of the now short continuous or only partially attached bearing surface 3b (and also in the case of the top part 19a and also the air guide plate 6) . 11A shows in the middle an air guide plate 6 with a support surface 3b 'for insertion into the slot 3c' and on the left an air guide plate 6 with an extension part 6a upwards. The formation of air baffle plates without attachment part 19a or groove (FIGS. 8-11) can also be deeper than the heat exchanger 8 and can also be formed in shafts, troughs, behind cladding, etc. in terms of airflow technology. With sales Using air guide plates 6 with a shorter contact surface 3b ', the attachment part 19a can be omitted. In FIG. 11B, the boom 3a has a slot 3c ″ executed to form slats 13.

In the case of heat exchangers with laterally arranged sheets or terminations, at least one hook 7 is formed from the brackets 3 a for resting on these terminations. If the air baffle plate 6 is higher than the heat exchanger 8, it can also have bends and cooperate with partition plates in hollow walls, ceilings and floors.

In another embodiment, such support parts 11 can have brackets 3a, which are designed to hold and / or clamp air guide plates 6 and also pipes on one or both sides.

Fig. 12 shows two heat exchangers 8 arranged one above the other at a distance from a support surface. If these heat exchangers 8 are not connected one above the other, at least one connecting part 20 must be arranged between two heat exchangers. Preferably in each case on the outer tubes in multi-tube heat exchangers. The connecting part 20 consists of two preferably identical insertion parts 2 with hooks 7, with extensions 3a preferably being arranged on both sides between the insertion parts 2; preferably also on both sides of the insert parts 2. Between the heat exchangers 8, connecting parts 20 connect / hold them immovably. The brackets 3a prevent the upper heat exchanger 8 from tilting or prevent the fins 13 from rubbing against one another. This version can also be used for a heat exchanger 8 and a bypass etc.

13 shows a heat exchanger 8 at a distance from a support surface and a bypass holder 1b inserted between fins 13 in the manner of operation as a connecting part 20, but the upper part is only for holding a pipe or other lines or a bypass 1a by a claw 15 educated.

Fig. 14 shows a heat exchanger 8 with a support part 11. Between the hooks 7 on both sides resilient clamps 9 are formed, these have support points 9a, which clamp the pipe 1 on both sides above the center of the pipe 1 and thus by the support of the fins 13 the boom 3 a hold the support part 11 and the heat exchanger 8 together. The tube 1 is not in the groove 10, it is a free space 9b recessed. The clamps 9 with the support points 9a can also be formed from the hooks 7, clamps 9 and or hooks 7 can also be used, for example made of plastic, spring plate, wire, etc.

FIG. 15 shows a trough 47 and an edge strip 42 which is formed or plugged in from the trough side part 48. A grating frame 32 with a grating (not shown) is positioned on this edge strip 42. Such lattice frames are attached at least on both sides of a tub, groove, recess, shaft, etc. This all-round or only two-sided frame is connected to the edge strip 42 during manufacture or on site. The lattice frame 32 consists of a lattice support 35 and a frame side part 33. On the underside of the lattice support 35 there is a T-groove 34, in which a fastening bracket 45 (in section, dashed lines) finds a guide with its insertion plate 39 and by means of a screw 46 is attached or fixed, the screw pushing the insertion plate 39 onto the extensions 43. The mounting bracket 45 consists of an insertion plate 39 and, offset downwards, a mounting plate 40. Both parts are connected by a central part. The lattice frame 32 is fastened with the edge strips 42 by fastening the insertion plate 39 in the T-groove 34 and the fastening plate 40 with the edge strips 42, the latter fastening by means of screws, rivets, clamps, welding, soldering, adhesives and other fastenings or else only lying on. The edge strip 42 is formed with its also extended part as a wall anchor 41 and can be smooth and also have necessary changes or mounted parts continuously or at intervals in order to function as a wall anchor or also as a fastening or as a support surface. If the edge strip 42 is not equipped with an extension or a wall anchor, or if this is not used as a wall anchor 41 or fastening or support, the fastening plate 40 takes over this function and can therefore also have wall anchors 41, extensions etc. or corresponding training , which is favored by the arrangement at intervals. The fastening of a lattice frame 32 with an edge strip 42 by means of a fastening bracket 45 makes it necessary to attach at least one web 36 and possibly also an enlargement part 37 to the inner part of the lattice frame 32 or the lattice support 35 from the underside of the extension 43, since otherwise as a result of the difference in height the mounting plate 40 and the lattice support 35, a continuous gap between the lattice support 35 or extension 43 and edge strips 42 or a support surface with the frame, etc. is formed, and as a result there would be no secure support surface. In another embodiment, the T-groove 34 is on the back of the Frame side part 33 formed, but here the mounting plate 40 is formed at an angle and continue to be used in the forms described.

The fastening bracket 45 from FIG. 15 is shown in detail in FIG. 16. The fastening plate 40 is formed or attached so that it is offset from the insertion plate 39 so that at least one extension 43 is positioned between the insertion plate 39 and the fastening plate 40 and the entire fastening bracket 45 can be clamped in a T-groove 34 by the screw action. The insertion plate 39 and optionally a central part 50 has a hole 38, preferably with a thread for a screw. The fastening plate 40 also has a hole, but can also be fastened in other ways.

17, an edge strip 42 is shown without a trough 47. A lattice frame 32 is mounted on such an edge strip 42, attached attached to reinforce the overall construction, therefore the lattice frame 32 can be relatively weak, and form a straight lower contact surface, namely to be able to use the edge strip, which then also attaches accordingly can be, and to have a training of a wall anchor 41 available. For wooden door structures, shafts with wooden frames or wooden parts, etc., the edge strip can be fastened, for example, by nailing, screwing, clamping, gluing, etc., or is only clamped when installed, etc. The use of edge strip 42 as wall anchor 41 becomes more widespread of the edge strip 42 reached. A groove 5 "between extension 43 and enlargement part 37 is provided for stiffening parts, fastening parts, corner connections or corner reinforcement. In another embodiment, the edge strip 42 is omitted and therefore the fastening bracket 45 with its fastening plate 39 as fastening part for documents or as a wall anchor 41, for example also by extending the fastening plate 40. The web 36 and possibly also the enlargement part 37 are at least as high as the fastening plate 40. A special embodiment is characterized as a fastening bracket 45 in which can be displaced along the lattice frame 32 and subsequently fixed guided a T-groove 34, and the fastening bracket 45 connected to an edge strip 42 acts as a wall anchor 41 or as a support part, a web 36 and possibly also an enlargement part 37 being as high or slightly lower than the distance from the underside of the forts etches 43 to the underside of the mounting plate 40 in the fixed state of the mounting bracket 45 on the lattice frame 32. In another special embodiment the T-groove 34 is attached to the outside of the frame side part 33 and the fastening plate 40 is angled at the level of the support (edge strips, support surface).

In Fig. 18, a mounting bracket 45 is formed from an insertion plate 39, a mounting plate 40 and between them a central part 50 (washer, sleeve, etc.). A screw 46, for example a worm screw, presses the insertion plate 39 onto the extensions 43 and subsequently the fastening bracket 45 is fixed to the lattice frame, as a next step the fastening bracket 45 can be connected to an edge strip 42. The edge strip 42 has an edge strip step 42a. Such a web 36 and also an enlargement part 37 can be omitted in certain designs. Lattice frames 32 with a continuous profile are made of metal or plastic.

19 shows a lattice frame 32, but instead of a frame side part 33 there is at least one, preferably continuous, spring 33a which holds push-on frame side parts 33b with or without a groove, for example made of wood, also by means of a tongue and groove connection by clamping, gluing, etc.; to match, for example, a wooden stick 33c of a roller grate. An edge strip 42 has on the inside a guide wall 48a which is angled out of the edge strip and which is delimited inside or outside a tub side part (48 from FIG. 15) and can be fitted with a necessary play (see FIG. 22). Staggered outwards shows a different position of the guide wall 48a. In another embodiment, this lattice frame can also be designed without a web 36.

In FIG. 20, instead of the web 36, a guide wall 48a is formed from the underside of the lattice support surface 35, which (and also in the embodiment according to FIGS. 19, 21, 22) can also be formed in pairs, on the outside or on both sides of the lattice frame 32 and which is compatible with at least one tub side part 48 (FIGS. 15, 22) or a frame 48b or an angular configuration and thereby finds a support and / or a guide, so that the grid frame 32 with the guide wall 48a also by means of an adjusting device (FIG. 22) The height can be varied, for which purpose, for example, a screw 46 is mounted in a sleeve 46a in FIG. 20, the height of the sleeve, the screw and the guide wall being dimensioned depending on the overall construction of the floor convector, shaft, channel, etc. The guide wall 48 a is slightly displaced outward to cover a tub side part 48, seen from above. The screw 46 is concreted or foamed, etc. In Fig. 21, the lattice frame 32 is placed on a frame 48b which forms a shaft, channel, etc. and is suitable for floor convectors. Here, too, the height of the lattice frame 32 can be adjusted by means of a screw 46, the screw of course having to be removed after the lattice frame has been fixed.

In FIG. 22, a lattice frame 32 with a guide wall 48a is placed outside a tub side part 48 and the height is adjustable by means of a screw 46 and a continuous or spaced screw rest 48c. The parallel guide wall 48a and the tub side part 48 (shaft, channel, etc., frame 48b, etc.) largely prevent the penetration of concrete and foaming agents into the shaft.

23 shows a lattice frame 32 with a spring 33a (two springs 33a are also possible). A web 36 is not provided in this type of attachment. An insertion plate 39 is inserted into the T-groove 34 and is fixed by means of a screw 46, then the fastening is carried out under the edge strip 42 by means of a nut 46a, and if necessary a washer 46b is arranged between the edge strip and the nut.

The exemplary embodiments described above in all the figures and their descriptions show preferred but not exclusive variants, and all variants can also be combined with one another.
