Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a stack chimney.

[Conventional technology]

Conventionally, to construct a collective chimney, concrete blocks were joined together with mortar and stacked into a rectangular tube shape to form a frame wall, and the required number of chimney flue pipes were stacked in series within that frame. At the same time, reinforcing bars were placed between the frame wall and the ceramic pipes, and concrete was poured.

[Problem that the invention seeks to solve]

In the above-mentioned conventional collective chimney, if concrete is poured between the mortar and the ceramic pipe before the mortar has solidified and the frame wall has the required strength, the concrete blocks will shift and protrude or collapse. There was a problem in that the concrete was poured after waiting several days until the frame wall had the required strength, resulting in a long construction period.

In addition, in order to avoid the above problems, concrete is poured by attaching support panels, etc. to the outside of the frame wall, but it takes a lot of time and effort to attach and remove the support panels, etc. There was a problem of increased branch costs.

Furthermore, in any of the above cases, the ceramic pipes tend to shift when concrete is poured, so the concrete cannot be tamped down sufficiently, resulting in weak areas in the concrete layer, and the required strength is not achieved. There was a problem that I could not get it.

The object of the present invention is to eliminate the above-mentioned conventional drawbacks at once, and to enable efficient construction of a chimney stack with excellent durability.

[Means for solving problems]

In the collective chimney of the present invention, first, the ceramic pipe connects the outer pipe body and the inner pipe body located inside the outer pipe body at a required interval with a plurality of partition walls whose upper and lower ends coincide with the outer pipe body. , a plurality of hollow parts partitioned by the partition walls are formed between the outer pipe body and the inner pipe body, and a recess for placing the horizontal strip is provided at the upper end of each partition wall, and The upper end is positioned to protrude beyond the upper end of the outer tube, and the lower end of the inner tube is positioned inward than the lower end of the outer tube.

Then, a horizontal line is placed in the recess of the partition wall of the lower part of the ceramic tube, a packing is placed on the upper edge of the inner tube, joint mortar is applied to the upper edge of the outer tube, and the above-mentioned The upper tier of ceramic pipes is fitted and mounted.

Further, it is characterized in that the vertical reinforcements inserted into the vertically communicating hollow parts and the horizontal reinforcements are tied together, and the hollow parts are filled with concrete.

[Effect]

Vertical bars set up at predetermined positions are inserted into the hollow part, and the recess formed on the lower side of the upper tier ceramic tube fits into the upper end of the inner tube body of the lower tier ceramic tube to assemble it. Because it is fixed, it will not shift accidentally, and the assembly work can be carried out efficiently.

The horizontal striations are easily supported in a predetermined position by the recesses provided in each partition wall, and are tied to the vertical striations, and are supported by the inner and outer tube bodies and partition walls of each stacked ceramic tube. Concrete is poured into the hollow section into which the vertical reinforcements are inserted, so the overall structure is strong, and the outer tube does not accidentally shift and protrude. It can be easily constructed by pouring concrete immediately after assembling ceramic pipes without attaching support panels or the like to the outside of the pipe body.

In other words, concrete can be placed efficiently, the concrete can be sufficiently tamped to obtain the required strength, and a highly durable chimney can be constructed.

In this way, the efficiency of the porcelain pipe assembly work and concrete casting work is increased, and the work of attaching and removing support panels etc. can be omitted, thereby shortening the construction period and reducing construction costs.

The illustrated embodiment will be described below.

The ceramic tube 1 shown in FIGS. 1 and 2 is for constructing a collective chimney with a triangular cross section, and has an outer tube body 2, an inner tube body 3, and a partition wall 4 integrally formed.

As mentioned above, the outer tube body 2 has a triangular cross section, and the inner tube body 3 has a circular cross section, each having the same length, and the inner tube body 3 is coaxially arranged in the center of the outer tube body 2.
The upper end portion of the inner tube body 3 has a length corresponding to about 1/6 of the total length and protrudes upward from the upper end of the outer tube body 2, and the lower end portion of the inner tube body 3 has a length corresponding to about 1/6 of the total length of the outer tube body 2. They are arranged inward from the lower end of the body 2 and connected to each other by a partition wall 4.

Each partition wall 4 has the same length as the outer tube body 2 and is shaped like a gutter with a semicircular arc cross section, and is arranged along the axial direction at three corners of the outer tube body 2, and Both long edges connect to the inner surface of the outer tubular body 2, the central part connects to the third equal parts of the outer peripheral surface of the inner tubular body 3, and the upper and lower edges are flush with the upper and lower edges of the outer tubular body 2. It is molded into a state.

Moreover, semicircular notch recesses 5, 5 are formed on both sides of the upper edge of each partition wall 4.

Hollow portions 6 to 11 are formed between the outer tubular body 2 and the inner tubular body 3, which are partitioned by a partition wall 4.

In order to construct a collective chimney for a two-story house by stacking the ceramic pipes 1 having the above configuration, three reinforcing bars 13 are installed on a concrete foundation 12 installed along the outer wall of the building (not shown). The corresponding hollow parts 6, 7, and 8 are inserted, and the ceramic pipe 1a is placed on the concrete foundation 12 with one corner facing the outer wall of the building and with joint mortar 14 applied ( Figures 3 and 4).

Next, an annular packing 15 made of asbestos is placed on the upper edge of the inner tube body 3 of the ceramic tube 1a, and a horizontal strip 16 bent into a triangular shape is placed in each notch 5, and longitudinal strips are placed at important points. 13 with wire, apply joint mortar 17 to the upper edge of the outer tube body 2, fit the hollow portions 6, 7, 8 of the ceramic tube 1b into the vertical strips 13, and tighten the inner tube body 3.
While placing the lower edge of the on the packing 15,
The lower edge of the outer tube body 2 is placed on the joint mortar 17 and placed on the ceramic tube 1a (FIG. 3).

Stack 5 to 7 ceramic tubes 1 in the same way, 1
The floors are stacked at a height that connects the indoor chimneys (not shown), and the communicating hollow parts 6 to 11 of the ceramic pipes 1 are filled with concrete.

In this case, the outer tube 2 of each ceramic tube 1 is integrally tubular, and the upper end of the inner tube 3 and the lower end of the upper ceramic tube 1 are fitted. Therefore, each ceramic tube 1 does not shift or protrude, and the concrete can be sufficiently tamped. In addition, U-shaped formwork blocks are built around the conventional ceramic tubes, and the space between them is There is no need to separately install support panels to prevent the formwork blocks from protruding or shifting when filling with concrete.

Next, the ceramic pipes 1c for connecting the indoor chimney on the first floor are assembled in the same manner as the ceramic pipes 1a and 1b (fourth
figure).

This ceramic tube 1c is different from the ceramic tubes 1a and 1b by the inner tube body 3.
The difference is that a circular through hole 18 (the inner tube 3 is not shown) for connecting an indoor chimney is formed in the opposing part of the outer tube 2, and the other configurations are the same. It is. A joint pipe 19 made of ceramic or metal is fitted into both through holes 18.

Furthermore, on the ceramic tube 1c, ceramic tubes 1a and 1b are placed.
Assemble the required number of ceramic pipes 1 in the same manner as in the case of , and in the place where the indoor chimney on the second floor of the building will be connected, stack ceramic pipes of the same shape as the ceramic pipes 1c (not shown) in the same way. A joint pipe is attached, and the ceramic pipe 1 is further assembled on top of it. As a result, each ceramic tube 1
A collective chimney having a flue formed by communicating the inner pipe bodies 3 is constructed.

Ceramic pipe 1 of the collective chimney constructed in this way
The indoor chimney on the first floor is connected to the joint pipe 19 attached to c, and the indoor chimney on the second floor is similarly connected to the corresponding joint pipe. In addition, at the joint between the assembled chimney and the eaves, the corners of the ceramic pipes 1 face toward the ridge, so snow on the roof slides down along the slopes on both sides of the ceramic pipes 1. It's easy.

5 and 6 respectively show other examples of ceramic tubes, and the ceramic tube 20 shown in FIG. The position is different, but the other configurations are the same.

The ceramic tube 22 in FIG. 6 is different from the ceramic tube 1 in that the outer tube body 23a has a square cross section.
The shape and position of the partition wall 24 that connects the inner tube body 23b and the inner tube body 23b are different, but the other configurations are the same.

In addition, in the above embodiment, the inner tube body has a circular cross section,
Although a case has been described in which the outer tube has a triangular or square cross section, these shapes are not limited to the above shapes, and may be any other suitable shape such as a polygon of pentagon or more, or an ellipse.

In addition, in the above example, each ceramic tube is not glazed, but glaze is applied to the outer surface of the outer tube body and the inner surface of the inner tube body to enhance the decorative and waterproof effect and to prevent frost damage and smoke damage. It's okay.
