Description

Auxiliary device for making chimneys

The construction of a fireplace will go along with the rest Masonry carried out «although no one knows afterwards how the chimney actually looks from the inside in its chimney draft * sees. Under the bricks there are many so-called field fires, which are because of their incorrect fire disgustingly thick and crooked are · These stones are often used to build the chimney «because they are here invisible, but often the stones by 1, 2, 3 or up to 4 cm inward protrude into the chimney and thus the chimney does not comply with regulations · The flue pipe in the chimney is thereby narrowed many times, and the chimney cannot be drawn due to constant pushing and swirling of the abdominal gases · Also with When the chimney is drawn in, the smoke pipe is mostly narrowed and It is also possible that a ladle of mortar should be used in the masonry the chimney falls, which is particularly disadvantageous when the mortar just stuck on a ledge and there hardened. It is also the case with chimneys with a smaller diameter not possible to remove all mortar that oozes out of the stone joints in the belly pipe. When the latter is crossed off it mostly falls into the chimney, so it often happens that a finished chimney of 8 or 10 m Height up to 1.50 m has been backfilled. If the Fireplaces that need to be cleaned with a smear board are that catch rough and form bus catchers · Interior plaster is also used

easily swept away by the chimney broom "

Pie hiring has set itself the task of the enumerated Hachteile, which so far in the manufacture toh Fireplaces, even when using τοη special chimney stones for the manufacture of chimneys, arise to eliminate and to simplify the amine production considerably.

The Beuerung concerns an auxiliary gate for the preparation. position τοη chimneys and consists of one over several Chimney stone layers extending and the chimney cross section adapted as well as height adjustable in the chimney foot Frame with surfaces for inserting layers of chimney stones arranged one on top of the other. The one through the The advantage achieved by the innovation can be seen in aarin that the bricklayer only sets up the frame in the rural area and put the chimney stones on the frame. When the building has grown, the frame is raised in height, whereby it is advantageously determined in a joint, after which you can roughen up without measuring the Chimney etc. «becomes necessary. You can use τοη usual bricks between each height graduation of the frame, for example 8, 9 or 10 layers, before loosening the frame from the joints and around another 10 layers higher

In the following the invention is based on only one Embodiment illustrative drawing explained in detail; show it :
