Through-bolts (3) pass vertically through the group (S). One end of the through-bolts (3) is provided with a flange (2) being formed by a pair of oppositely situated and mutually joined plates (21) having holes (22) for the through-bolts (2) that are coupled with said flange (2).

Description

Building block for chimney construction

Technical field

The invention is a building block for building a chimney made of mantle blocks that surrounds the chimney liner and wherein the mantle block body is typically filled with relief holes.

BACKGROUND OF THE INVENTION Normally, individual sheath blocks are stacked on top of each other, where the separating joints are provided with a mortar mixture. Such a chimney construction shows low productivity. Therefore, the individual sheathing blocks are assembled into groups where the sheathing blocks are also connected by a mortar mixture. The casing blocks are interconnected by bolts, where their ends, usually formed by screw connections, are seated in recesses. Such recesses are formed by separating the portions of the mantle block at the corners. After joining the individual groups of cladding blocks during the construction of the chimney, the separate parts of the cladding blocks are added to the mortar mixture. Such chimney construction is characterized by the difficulty of handling the prepared groups.

The essence of the solution

A building block according to the invention for the construction of a chimney consisting of mantle blocks, wherein at least two mantle blocks form a group of superimposed mantle blocks which are vertically interwoven by bolts. The shell blocks located at the end of the group are provided at one end with a flange to which the bolts are connected. The flange is formed by pairs of opposed and interconnected washers provided with bolt holes. With such a solution, there is no need to separate the portions of the end mantle blocks and, moreover, it facilitates the continuity of one group of mantle blocks to another.

In one case, the flanged bolts are welded together, and in another embodiment, the flanged bolts are bolted together. Both versions guarantee a compact assembly.

If the bolts are terminated by screw joints formed by a threaded end with a nut, where the washers in each of the pairs are joined by spacers, as well as the individual pairs of washers are reinforced and cast with concrete filling, the flange thus made becomes an integral part of the chimney.

If the stiffeners are interconnected, they also define the final dimension of the flange.

Suitably, the bolts, as well as the holes in the pairs of oppositely placed washers, are located at the corners of the cladding block group and the spacers are located closer to the center of the cladding block. The connection of the bolts to the flanges thus becomes more accessible, both for bolted assembly and welding.

For assembly, it is advantageous if the group is at the opposite end to that of the flange ending with a removable plate through which the bolts pass through the threaded end with the nut. Such a removable plate facilitates handling, especially when hinged.

DETAILED DESCRIPTION OF THE INVENTION

The building block is intended for the construction of a chimney consisting of groups S of cladding blocks 1. The cladding blocks 1 are longitudinally interwoven by bolts 3. The cladding blocks 1 located at the end of group S are provided at least at one end with a flange 2 to which the bolts 3 are connected. The bolts 3 are connected to the flange 2 by welds 33, see Fig. 3 or by bolted joints 31 see Fig. 2. The flange 2 is formed by pairs of opposed washers 21, where the washers 21 on the outside are provided with holes 22 for bolts 3. The washers 21 in each of the pairs are joined by spacers 23, as well as the individual pairs of washers 21 are provided with stiffeners 24 and embedded with concrete filler V. The stiffeners 24 are interconnected. The bolts 3 as well as the openings 22 in pairs of opposed washers 21 are located in the corners of the group S of the cladding blocks 1, where there are generally relief holes in the cladding blocks 1. The spacers 23 are located closer to the center of the skeleton block 1. The group S is at the opposite end of that provided with a flange 2 terminated by a removable plate 4 through which bolts 3 pass through a threaded end 311 with a nut 32. The removable plate 4 is provided with a hinge 44 for example.

The bolts 3 are fastened in the flange 2 by a screw connection 31 or by a weld 33. Individual bolt blocks 1 are slid onto the bolts 3, which are connected to each other by a mortar mixture. A removable plate 4 is applied to the last skirting block 1 and secured with bolted connections 31. The flange 2 is filled with concrete filler V. This makes the flange 3 an integral part of the whole group S. The assembled group S is hinged 41 with the crane and Group S is deposited on the previously established Group S, which is first provided with a mortar mixture. Flange 3 established groups

S is connected to the projecting bolts 3 by screw connections 31 or welds 33. Subsequently, the removable plate 4 is removed, the loose surface is provided with a mortar mixture and a further group S of the cladding blocks 1 can be seated.
