DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a building exhaust structure.

[0002]

2. Description of the Related Art Conventionally, as a structure for exhausting indoor air from a building such as a factory building or an incinerator building having a combustion device installed therein, a roof fan or a monitor provided on a ceiling portion of the building is used. There was something. That is, there has been a type in which high-temperature air staying in the ceiling is forcibly discharged by a roof fan or naturally exhausted from a monitor in which the ceiling roof is formed in an uneven state.

[0003]

However, the above-mentioned conventional exhaust structure for a building has the following problems. For example, in summer, the temperature of the air stagnating in the ceiling of the building often reaches 40 ° C. or higher, and efficient exhaust of the building is required. However, when exhausting with a roof fan, the capacity of the roof fan affects the exhaust efficiency.If the capacity is small, sufficient exhaust cannot be performed, and if a roof fan with a large capacity is installed, Although the exhaust efficiency is improved, the initial cost and the running cost of the facility are required, which is uneconomical. On the other hand, it is possible to provide a large monitor without using a roof fan, but in this case, it is difficult to secure the monitor part itself due to restrictions on the height of the building, etc. Inconveniences such as damage occur.

SUMMARY OF THE INVENTION An object of the present invention is to solve such a drawback of the prior art and to provide a simple and economical structure which is excellent in building exhaust efficiency and which does not impair the design of the building. To provide.

[Means for Solving the Problems]

(Structure 1) A characteristic structure of the present invention for achieving this object is that, as set forth in claim 1, an upper communication portion for connecting and connecting the upper space of the building and the inner space of the outer cylinder is provided. is there. (Operation / Effect) According to the building exhaust structure of the present configuration, high-temperature building air accumulated in the upper part of the building can be efficiently exhausted without using a special forced exhaust device such as a motor fan. That is, in the present invention, the high-temperature air in the building is efficiently exhausted by utilizing the natural ventilation power of the chimney through the space between the outer cylinder and the inner cylinder of the chimney already provided. It is assumed that. When the upper part of the building and the outer cylinder of the chimney communicate with each other at the upper communication part, the higher the temperature of the exhausted building air and the higher the height of the chimney, the greater the natural ventilation force. If the natural ventilation power is large, the exhaust efficiency of the building air also increases. As a result, there is no need to provide a motor fan or monitor at the top of the building, so the cost of installing the motor fan and
The running cost of the equipment becomes unnecessary, which is economically advantageous. Further, even when the height of the building is restricted by height restrictions or the like, the space inside the building can be effectively used if a space for providing a motor fan or a monitor becomes unnecessary. It does not impair the design of the exterior view. Further, as another effect, exhausting the high-temperature air in the building through the outer cylinder of the chimney is a general combustion exhaust gas exhausted through an inner cylinder provided inside the outer cylinder. Can be expected to have the effect of keeping the temperature of the exhaust gas, which contributes to the prevention of white smoke when the combustion exhaust gas is released to the outside air.

(Structure 2) Further, according to the present invention, as described in claim 2, an inspection passage inside the outer cylinder and around the inner cylinder along the longitudinal direction of the inner cylinder. It is also characterized by the fact that it is provided with a. (Operation / Effect) With this configuration, an inspection passage for inspecting the outer cylinder, the inner cylinder, and the like can be used as it is as a building exhaust path. Therefore, it is possible to provide an efficient building exhaust structure only by making a simple improvement such as providing the upper communication portion.

Embodiments of the present invention will be described below with reference to the drawings. The present invention is mainly used when the room temperature inside the building 1 becomes high and it is necessary to exhaust the high-temperature air. The building 1 is, for example, a factory building or an incinerator building having a combustion device 2 provided therein. In the case of such a building 1, in summer, the temperature of the air near the ceiling often exceeds 40 degrees, and efficient exhaust of the building air is required. As shown in FIG. 1, a building exhaust structure of the present invention connects a building 1 and a chimney 3 attached to the building 1 with an upper communication portion 4. That is, the high-temperature air in the building 1
The exhaust is efficiently exhausted by the natural ventilation power of the chimney 3. The chimney 3 is composed of an outer cylinder 5 and an inner cylinder 6. The inner cylinder 6 is connected to the combustion device 2 and the like via a lower communication portion 7, and is for exhausting normal combustion exhaust gas to the outside. The number of the inner cylinders 6 is not limited to one. When a plurality of the combustion devices 2 are provided in the building 1, the inner cylinders 6 may be provided by the number of the combustion devices 2. The inner cylinder 6 is covered by the outer cylinder 5. The outer cylinder 5 is usually used as a structural body for supporting the inner cylinder 6, or
It has a function as a decorative member for covering and covering the inner cylinder body 6 and as an inspection passage 8 for inspecting the inner cylinder body 6. In the present invention, in addition to the above functions,
It has a function as an exhaust passage for exhausting high-temperature air in the building 1. The above-described natural ventilation force is such that the higher the temperature of the gas to be discharged, the higher the height of the outer cylinder 5, and the more the space between the outer cylinder 5 and the inner cylinder 6. It increases as the cross-sectional area increases. Therefore, if the chimney 3 is appropriately designed according to the capacity of the indoor space of the building 1 or the assumed maximum indoor temperature, the best exhaust efficiency can be obtained. As described above, according to the building exhaust structure of the present invention, it is possible to improve the design of the building 1 without using a roof fan, a monitor, or the like, and furthermore, economically reduce the internal air of the building 1 and ,
Exhaust can be performed efficiently.

[Other Embodiments] <1> As shown in FIG. 1, the upper communication portion 4 can be configured by providing an opening / closing mechanism 9. For example, if the opening / closing mechanism 9 is closed in winter to maintain the high-temperature air in the building 1, it can be used as heating for the equipment in the building 1 or for equipment attached to the building 1. Become. <2> Further, an inspection passage 8A can be provided inside the upper communication portion 4. With this configuration, the intermediate portion of the chimney 3 and the building 1 can be moved back and forth, and it is not necessary to perform the inspection work inside the outer cylinder 5 from the lower end portion of the chimney 3 without fail. Efficiency is improved.
