5 Installation template for installing cladding bricks to a chimney

7 The invention relates to a setting template for setting mantle stones

&bgr; to a chimney having the features mentioned in claim 1.

10 A mantle stone has on its surface and its surface

11 facing away from the bearing surface, each has a through hole. The mantle stone

12 is hollow inside and forms the outer molding for the installation process.

14 It is known to stack several such casing stones on top of each other. is In this case, the casing stone on top always rests with its bearing surface ie with a layer of mortar in between on the surface of the casing stone below. The mortar layer serves as a joining agent to hold the casing stones together as firmly as possible. When mortar is mentioned here as a joining agent 19, it is the usual and preferred form of a joining agent for stacking casing stones. However, other types of joining agent are also possible.

21 Joining agents, such as adhesives, putty etc., are generally used to carry out the

22 procedure is usable and suitable.

24 One problem with the mortar layer is that it is not sufficiently

25 must be large in order to ensure lasting cohesion between the individual

26 mantle stones, and at the same time must not be so thick,

27 that under the pressure of the overlying mantle stone mortar from the joint

28 between two superimposed mantle stones and into the

29 mantle cavities.

3i It is known that a plate-shaped

µm placement template to be placed on the surface of the lower casing stone.

33 The template completely covers the cavity in the mantle stone and

34 additionally covers the side edge surrounding the cavity

35 partially. The uncovered, wreath-like enclosing of the template

This edge surface of the side edge serves as a surface for applying the mortar. The

37 The edge area is dimensioned in such a way that, on the one hand, the sufficient

16 January 1991

&igr; amount of mortar can be applied to hold the casing stones together and

2 on the other hand, no mortar can penetrate into the casing stone cavities.

4 The outer moulded pieces, the casing stones, are used in the well-known

5 Process the inner fittings formed by fireclay pipes under

&bgr; Intermediate layer of insulating material inserted into the casing stone cavities.

&bgr; The end section of the chimney protruding from the roof structure can

&bgr; either be clad with a prefabricated chimney head

&ohgr; or walled in on site. With such a walled chimney head

11, however, it is necessary to replace it with a slab of in-situ concrete on the top

12. This concrete slab will be manufactured on site.

13 Penetration of concrete into the cavities or the inner mould parts

u prevent it is necessary to install a spacer between the chimney and the concrete slab.

is lost formwork panel to be inserted. This formwork panel has the well-known

The process involves a cross-section of a pipe which is ultimately to be inserted into the outlet pipe

ir adapted through hole. To create a through hole

ie the same size in the concrete slab, it is necessary to use a

The formwork core is to be inserted into the cavity of the uppermost casing stone.

µ Such formwork cores are preferably made of expanded polystyrene.

22 After the concrete slab has been manufactured, both the superfluous template

23 and the superfluous formwork core must be disposed of.

25 The formwork core cannot be reused after use anyway

26 and the reusability of the positioning templates usually fails due to &zgr;? the different dimensions of different chimneys. The

28 Each building contractor is therefore required to always maintain a warehouse with various

2&bgr; large templates and with different sized formwork panels.

µ Simplification, especially to minimize planning and material

31 Control effort, mantle stones are used in the conventional process

32 together with a matching template and a matching formwork plate

33 delivered.

35 The invention is based on the object of providing a positioning template of the type

and in particular to reduce the amount of disposable parts

37. This object is achieved by the invention contained in claim 1.

This combination of features is solved.

16 January 1991

2 The inventive design of the template makes it possible to

3 to be used as a formwork panel when carrying out the process.

4 The material, which has to be disposed of after relocation and is therefore worthless,

5 template is thus sensibly recycled as a lost formwork panel. Compared to &bgr; known templates according to the state of the art, the

7 inventive template without disadvantages its primary task in the processing

8 mortaring the mantle stones.

io In the inventive design of the template according to claim 2,

ti compared to the inventive embodiment according to claim 1 in addition to the

i2 lost mold core, preferably made of expanded polystyrene. The

&eegr; inventive embodiment of the template according to claim 2 is thus with respect

14 its secondary function as a formwork and core element. The

The embodiment according to claim 2 combines the advantageous and consistent

the material savings with a reduction in the environmental impact of waste parts,

&igr;? The cost burden is therefore reduced as well as the environmental impact.

ie With regard to environmental impact, the elimination of the

20 Foam polystyrene mold core advantageous because foam polystyrene is not recyclable

21. Furthermore, the invention prevents such expanded polystyrene

22 mold cores are disposed of improperly and thus in an environmentally harmful manner. This

23 Eliminating the risk of improper disposal also reduces the

24 environmental liability reasons indispensable expenditure for

25 Control measures.

27 Claims 3, 4 and 5 teach particularly advantageous for the use

28 Further developments of the template. The template is according to this teaching both

29 the inner moldings as well as the outer moldings advantageous

Furthermore, the template with these features is easy to create in just a few

si manufacturing steps and can be produced cost-effectively.

33 The formation of a visible notch according to claim 6 on the upper, the casing stone

34 opposite opening edge of the pipe sleeve facilitates the production of the

35 In-situ concrete slab. With this design, the concrete layer no longer has to be piled up exactly to the edge of the pipe sleeve, whereby there is always the risk that concrete particles will penetrate into the inner mold parts. On the other hand, the visible notch prevents the thickness of the concrete layer from

16 January 1991

&igr; is too small from the outset. This measure allows the use

2 of the template also by semi-skilled workers and increases the

3 Safety in use. This makes concreting easier and saves time.

s The measures according to claims 7 to 11 ensure that the

&bgr; Usage properties of the template advantageously further developed.

7 In particular, the template is firmly centered during the installation process

β on the mantle stone surface. The use of preferably standardized

&bgr; Fastening screws according to claim 10 are, on the one hand, technically

10 advantageous and cost-effective. The costs associated with these measures

11 advanced template is on the one hand easy to handle and its use

12 does not require a high level of qualification. The particularly solid and

13 Firm fit during application of the mortar layer on the &eegr; chimney surface.

ie The addition of a handle bar according to claims 12

i7 to 15 facilitates the manipulation and handling of the template,

te The use of centering pins is particularly simple in terms of manufacturing technology

ie also serves as a holder for the handle bar. The already mentioned advantageous

20 Use of standardized fastening screws additionally supports the

21 bayonet-type fastening of the handle bar according to claim 14. The

22 The handle bar wedges itself into the threads of the

23 fastening screws. This wedging is explained by the teaching of the claim

24 15 advantageously further trained.

26 The inventive, clamping fixation of the handle bar according to claims 16

27 and 17 is used for both the production of the template and the

28 The process of placing the mantle stones is advantageous. When making the template

29 eliminates the need to drill through holes in the handle bar, thus reducing the µm main production time and thus the production costs.

31 The handle bar fixed according to claim 16 is displaceable after the

32 Move the topmost mantle stone slightly with a screwdriver or

33 can be levered out of the template using a similar tool. The handle bar is

34 can thus be quickly separated from the template.

3&bgr; Another advantage of the entire device is that only the

37 easily disposable and recyclable handle bar remains. Particularly

38 cost-effective, environmentally friendly and recyclable is the

16 January 1991
