（産業上の利用分野）
本考案は、建造物における空調等のダクトの構
造に関するものである。[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to the structure of ducts for air conditioning, etc. in buildings.
従来、主に建物内に空調、冷暖房、排煙等のた

アングル鋼による枠を多数設けなければならない
等の欠点が多い。 Traditionally, it is difficult to process ribs in the direction of airflow for ducts built mainly for air conditioning, heating and cooling, smoke exhaust, etc. inside buildings, so when ribbing is done to strengthen the outer panel and prevent vibration, it is necessary to create ribs at right angles to the airflow. It is common to process horizontal ribs in the direction, but the horizontal rib type has a simple cross-sectional shape and only creates shallow ribs, so it is not effective in reinforcing the entire duct, and it is not perfect for plate vibration isolation. In addition, because the ribs are outwardly convex to avoid air resistance, dirt accumulates in the depressions formed on the inside bottom of the duct, and many angle steel frames must be installed to strengthen the duct. There are many shortcomings.
したがつて本考案はこの欠点を除くために考案
されたものであり、強度、性能、施工面において
も合理的な優れたダクトを提供するものである。 Therefore, the present invention was devised to eliminate this drawback, and provides a duct that is reasonably superior in terms of strength, performance, and construction.
（問題点を解決するための手段）
本考案は前述の問題点を解決するために、これ

組立を行うものである。(Means for solving the problem) In order to solve the above-mentioned problem, the present invention provides ribs in the vertical direction, which was thought to be difficult until now. In this cylindrical duct, as shown in FIGS. 2 and 3, a number of concave ribs 3 with high vibration resistance and bending stress are provided on each surface of the outer plate 2 in the same vertical direction as the air flow inside the duct using a special method. The block 1 is assembled by forming the block 1 by the following steps.
（作用、効果）
本考案は以上のような構造になつているので、
この方法により、ダクトの縦方向で形状も深く、
外板の歪みを吸収し耐振性に優れたものとなり、
補強性が高いためダクト全体の曲げ応力が増大す
る。(Action, Effect) Since the present invention has the structure as described above,
With this method, the shape of the duct is deep in the vertical direction, and
It absorbs the distortion of the outer panel and has excellent vibration resistance.
Due to its high reinforcing properties, the bending stress of the entire duct increases.

との結合ボルト穴のようなものがないため空気の
漏れがなく、又内部にごみが溜らない等の優れた
特性を有している。 Therefore, reinforcement with angle steel 7 at regular intervals in the longitudinal method is not necessary, so materials are saved and the overall weight is reduced.In terms of construction, workability is improved and the construction period is shortened, and in terms of performance, plate vibration is reduced. This completely prevents reinforcing angle steel in the conventional method.
It has excellent properties such as no air leakage and no dirt buildup inside because there are no bolt holes for connection.
