Description

The invention relates to the construction and can be used in the construction of vertical ventilation ducts, mainly for multi-storey buildings for industrial and auxiliary purposes.

Vertical ventilation ducts from masonry on bonding solution 1 are known.

The disadvantages of the known channels are the great labor intensity of the masonry of the channels and the impossibility of ensuring their high quality.

A lightweight construction block of polymeric material is known, with through voids and the sockets surrounding them, with which it enters the voids of blocks of the adjacent row 2.

However, in this building block, it is not possible to use drainage channels for ventilation ducts most often not made from polymeric materials, but from

stone and concrete, due to insufficient solidity of separately standing ventilation ducts, as well as due to insufficient sealing of the grooves between the blocks and great resistance to the air flow through the channel created by the ends of the sockets introduced into the voids of the channels.

Closest to the invention is a vent channel block, formed with a vertical through hole and a protrusion on the lower end surface on the side of the channel with a corresponding recess on the upper end surface to form a locking connection of the blocks 3.

The known block is characterized by insufficient sealing of the schvs between the blocks and the uncontrollability of their filling.

The purpose of the invention is to increase the quality and operational reliability of the channel and simplify the sealing of seams, as well as the formation of several vertical channels.

The goal is achieved by the fact that the vent duct block, made with a vertical through hole and a protrusion on the lower end surface to form a locking connection of the blocks, is made on the lower end surface with a bevel from the outer side surface of the block to the ledge, and vertical rebar grooves.

In addition, the blocks are equipped with an upper outer shelf corresponding to the gap between the channels.

FIG. 1 shows the proposed unit, a trodol vertical section along double channels; in fig. 2 shows section A-A in FIG. one; in FIG. 3 is a section BB in FIG. 1 (for single channel); in fig. 4 shows a section B-B in FIG. 1 (for dual channels); in fig. 5 is a cross-section of the FIG. 1 (for a group of three channels); in fig. 6 - axonometric blocks for a single channel.

The unit of the ventilation channel 1 is made with a vertical through hole 2 and a protrusion 3 on the lower end surface on the channel side with a corresponding recess 4 on the upper end surface to form a locking connection of the blocks. The block on the lower end surface is made with a bevel 5 from the outer surface of the block to the ledge 3. On the outer surface of the block, vertical grooves 6 for reinforcement are formed.

The blocks are equipped with an upper outer shelf 7 corresponding to the gap 8 between the channels.

In vertical furrows 6 during installation

channel at the construction site install the reinforcing channel rods, after which the seams between

the blocks and grooves with reinforcement fill

cementing solution (Fig. 1 and 3).

In the places of passage of the channels through the interfloor overlaps, there are holes 9 in the latter. The bore of the channel rests on the floor slab 10. The channel can be supported on the ceiling by double walls of the blocks on the plate edges at the hole (in this case, the size of the hole should correspond exactly to the dimensions of the block)

or through a gasket in the form of a support-coupling plate I. In the latter case, the washer 11 is provided with a socket 12, with which the washer passes through the hole 9 in the slab 10 to block the building. The upper end of the channel, which fits to the puck from the lower floor, is telescopically inserted into the socket 12. The washers are supported on the slab.

Excess gap between the top of the channel,

entered into the socket, and the washer itself, which is indicated by the sign D, serves as a means of extinguishing construction inaccuracies with deviations of the actual height of the floor from its nominal value for the project (Fig. 2 and 3).

The support-joint face 11 can be used to attach air intake or distribution grids 14 to it, or to connect downstream ventilation systems

floor. For this purpose, it is supplied with mortgage details 15 (Fig. 2).

The channels erected from the blocks may be single or executed in groups of two, three or more. To reduce the size of the gap 8 (Fig. 5)

between the trunks of the canals, the upper blocks of 16-storey canal chutes, included in the sockets of the shields, can be made with a quarter 17.

The installation of the channels from the blocks is carried out by laying them dry without mortar, using guide rails-patterns having a marking of rows of masonry, related to the height of the floor of the building. Bring the channel to the entire height of the floor, place the washer 11 on the overlap, while ensuring that the upper channel block 16 enters the washer socket, and fix the lock on the floor. After that, reinforcing rods fixed with wire clamps, which are placed in the horizontal joints of the masonry, are installed in the vertical grooves, and the grooves and grooves of the channel are rubbed with a cementing solution.

The sealing of difficult-to-reach horizontal seams in the adjacent walls of the channels during their matings is performed using long spatulas and a narrow scoop for feeding the solution into the gap 8 between the barrels of the channels. For the same purpose, the blocks of one of the pairing channels can be made with the upper outer shelf 7, which should correspond to the size of the gap between the channels.

The blocks can be ceramic and concrete of different composition, including gypsum concrete and lightweight aggregates.
