Description

本発明は、例えば、閉鎖型の構造物に関する。   The present invention relates to, for example, a closed structure.

従来より、廃棄物の処分場や、建物の新築・解体工事の工事現場など、作業エリアを覆う閉鎖型の構造物が提案されている。(特許文献1参照)。   Conventionally, a closed structure that covers a work area, such as a waste disposal site or a construction site for new construction or demolition of a building, has been proposed. (See Patent Document 1).

例えば、建物の新築工事では、以下のような閉鎖型の仮設構造物が提案されている(特許文献1参照)。この仮設構造物は、セルフクライミング機構を備えた複数のタワークレーンマストと、このセルフクライミング機構同士の間に架設された受梁と、この受梁の上に設けられた仮設屋根と、を備える。この仮設屋根は、屋根フレームと、この屋根フレームに張られた屋根シートと、を備える。   For example, in a new construction of a building, the following closed type temporary structure has been proposed (see Patent Document 1). The temporary structure includes a plurality of tower crane masts provided with a self-climbing mechanism, a receiving beam constructed between the self-climbing mechanisms, and a temporary roof provided on the receiving beam. The temporary roof includes a roof frame and a roof sheet stretched on the roof frame.

このような構造物によれば、全天候環境下で作業できるうえに、日射を抑制できるので、作業環境が向上し、作業効率を向上できる。また、内部の粉塵が外部に飛散しないので、近隣の環境に与える影響を小さくできる。   According to such a structure, it is possible to work in an all-weather environment and to suppress solar radiation, so that the work environment is improved and work efficiency can be improved. Moreover, since the internal dust does not scatter outside, the influence on the surrounding environment can be reduced.

また、この閉鎖型の構造物の内部空間では、作業員や重機により作業が行われている。そこで、作業員に新鮮空気を供給したり、重機の駆動に伴って発生する粉塵、騒音、排気ガス、排熱等を外部に排出したりして、内部空間の作業環境を確保する換気設備が必要となる。
そこで、特許文献1に記載の仮設構造物では、屋根シートの一部を巻き取ることで、仮設屋根の一部に開口を設けて、この開口を通して自然換気により換気を行うようになっている。
In addition, work is performed by workers and heavy machinery in the internal space of the closed structure. Therefore, there is a ventilation facility that ensures the working environment of the internal space by supplying fresh air to workers and exhausting dust, noise, exhaust gas, exhaust heat, etc. generated by driving heavy machinery to the outside. Necessary.
Therefore, in the temporary structure described in Patent Document 1, an opening is provided in a part of the temporary roof by winding a part of the roof sheet, and ventilation is performed through natural ventilation through the opening.

特開平7−82897号公報JP-A-7-82897

しかしながら、屋根面に開口を設けて換気を行うと、この開口を通して粉塵が外部に飛散したり騒音が漏れたりする場合があるうえに、この開口を通して雨水が浸入するおそれがあった。また、開閉機構を設ける必要があるため、仮設コストが高くなるうえに、開閉作業に手間がかかる、という問題があった。   However, if ventilation is provided by providing an opening on the roof surface, dust may be scattered to the outside or noise may leak through the opening, and rainwater may enter through the opening. Further, since it is necessary to provide an opening / closing mechanism, there is a problem that the temporary cost is increased and the opening / closing operation is troublesome.

本発明は、簡易な構造で、粉塵の飛散、騒音の漏れ、および雨水の浸入を防止できる構造物を提供することを目的とする。   An object of the present invention is to provide a structure that can prevent dust scattering, noise leakage, and intrusion of rainwater with a simple structure.

請求項1に記載の構造物(例えば、後述の仮設構造物1)は、壁(例えば、後述の外周足場10)および屋根(例えば、後述の折板屋根20)を備え、前記屋根と壁との間には、開口(例えば、後述の開口21)が形成されており、前記壁には、前記屋根の屋根面(例えば、後述の屋根面20A)よりも上方まで延びる延出部(例えば、後述の延出部31)と、当該延出部から略水平に延びて前記開口を覆う庇部(例えば、後述の庇部32)と、が設けられることを特徴とする。   The structure according to claim 1 (for example, a temporary structure 1 described later) includes a wall (for example, a peripheral scaffold 10 described later) and a roof (for example, a folded plate roof 20 described later), and the roof and the wall An opening (e.g., an opening 21 described later) is formed between them, and an extension portion (e.g., an upper part) extends above the roof surface of the roof (e.g., a roof surface 20A described later) on the wall. An extension part 31, which will be described later, and a collar part (for example, a collar part 32 which will be described later) that extends substantially horizontally from the extension part and covers the opening are provided.

この発明によれば、庇部の先端と屋根との隙間が換気口となり、開口から換気口までの経路は、折り返した経路となる。よって、開口を覆うように庇部を設けたので、雨が開口から内部に浸入するのを防止できる。また、よって、多くの粉塵がこの経路の途中で捕集されるから、粉塵が換気口から外部に飛散するのを防止できる。また、騒音がこの経路を通過することで反射や回折により減衰されるので、騒音減衰性能を発揮して、騒音が換気口から外部に漏れるのを防止できる。したがって、簡易な構造で、粉塵の飛散、騒音の漏れ、および雨水の浸入を防止できる。   According to this invention, the clearance gap between the front-end | tip of a collar part and a roof becomes a ventilation opening, and the path | route from an opening to a ventilation opening turns into a return | turnback path | route. Therefore, since the collar portion is provided so as to cover the opening, it is possible to prevent rain from entering the inside from the opening. Accordingly, since a large amount of dust is collected in the middle of this route, it is possible to prevent the dust from scattering from the ventilation port to the outside. In addition, since noise is attenuated by reflection and diffraction by passing through this path, noise attenuation performance can be exhibited, and noise can be prevented from leaking from the vent. Therefore, it is possible to prevent dust scattering, noise leakage, and rainwater intrusion with a simple structure.

換気口が屋根の内側に向いているので、換気口から騒音が漏れる方向あるいは粉塵が飛散する方向は、屋根の内側つまり近隣とは反対方向となる。したがって、騒音や粉塵が近隣に到達するのをより確実に防止できる。   Since the ventilation port faces the inside of the roof, the direction in which noise leaks from the ventilation port or the direction in which dust is scattered is opposite to the inside of the roof, that is, the neighborhood. Accordingly, it is possible to more reliably prevent noise and dust from reaching the vicinity.

構造物の内部空間は、外部の風の影響を受けにくく、気流が静穏であるため、暖かい空気が内部空間を上昇して、内部空間上部ほど高温な温度の層が形成され、構造物の屋根の近傍が最も高温な熱気だまりとなる。
そこで、開口および換気口を壁の上端つまり構造物の最も高い位置に設けた。よって、外部の風の強弱によらず、内部空間上部の高温な空気と外気との温度差による自然換気が行われるから、構造物の内部空間で重機や設備機器が駆動しても、これら重機や設備機器からの排熱や排気ガスを自然に排出できる。
Since the internal space of the structure is not easily affected by the external wind and the airflow is calm, warm air rises up the internal space, forming a layer with a higher temperature at the top of the internal space, and the roof of the structure In the vicinity of is the hottest hot air pool.
Therefore, the opening and the ventilation opening were provided at the upper end of the wall, that is, the highest position of the structure. Therefore, natural ventilation is performed by the temperature difference between the hot air in the upper part of the internal space and the outside air regardless of the strength of the external wind, so even if heavy machinery and equipment are driven in the internal space of the structure, these heavy machinery And exhaust heat and exhaust gas from equipment can be discharged naturally.

請求項2に記載の構造物は、前記屋根のうち前記庇部の直下でかつ前記開口の近傍には、立ち上がり部(例えば、後述の立ち上がり部34)が設けられることを特徴とする。   The structure according to claim 2 is characterized in that a rising portion (for example, a rising portion 34 to be described later) is provided immediately below the ridge portion and in the vicinity of the opening of the roof.

この発明によれば、開口の近傍に立ち上がり部を設けたので、雨水が屋根面を流れて開口から内部空間に浸入するのを防止できる。   According to the present invention, since the rising portion is provided in the vicinity of the opening, it is possible to prevent rainwater from flowing through the roof surface and entering the internal space from the opening.

請求項に記載の構造物は、前記壁には、前記開口から前記構造物の内部空間に空気を送る給気装置(例えば、後述の給気装置40)が設けられることを特徴とする。 The structure according to claim 1 is characterized in that the wall is provided with an air supply device (for example, an air supply device 40 described later) for sending air from the opening to the internal space of the structure.

内部空間において溶接作業や重機作業を行う場合、排気ガスが局所的に発生するため、給気が必要となることが多いが、この発明によれば、給気装置により、このような局所的に発生した排気ガスを確実に外部に排出できる。   When welding work or heavy machinery work is performed in the internal space, exhaust gas is locally generated, so air supply is often required. However, according to the present invention, such a local supply is performed locally by the air supply device. The generated exhaust gas can be reliably discharged outside.

また、給気装置についても、折り返し構造による騒音減衰機能および雨水浸入防止機能が有効に機能する。したがって、給気装置に消音装置を設ける必要がなくなり、コストを低減できる。   In addition, the air supply device also effectively functions as a noise attenuating function and a rainwater intrusion preventing function by the folded structure. Therefore, it is not necessary to provide a silencer in the air supply device, and the cost can be reduced.

請求項に記載の構造物は、前記壁は、複数段の枠組足場(例えば、後述の枠組足場11)と、当該枠組足場の外側を覆う防音パネル(例えば、後述の防音パネル12)と、を備え、前記給気装置は、前記枠組足場に設けられることを特徴とする。 In the structure according to claim 3 , the wall includes a multi-stage frame scaffold (for example, a frame scaffold 11 described later), a soundproof panel (for example, a soundproof panel 12 described later) covering the outside of the frame scaffold, The air supply device is provided in the frame scaffold.

この発明によれば、枠組足場に給気装置を設置したので、給気装置を枠組足場と一体に移動できるから、給気装置を内部空間の床面に設置する必要がなく、給気装置の盛替作業の手間を軽減できる。   According to the present invention, since the air supply device is installed in the frame scaffolding, the air supply device can be moved integrally with the frame scaffolding, so there is no need to install the air supply device on the floor surface of the internal space. The time required for refilling work can be reduced.

本発明によれば、庇部の先端と屋根との隙間が換気口となり、開口から換気口までの経路は、折り返した経路となる。よって、開口を覆うように庇部を設けたので、雨が開口から内部に浸入するのを防止できる。また、よって、多くの粉塵がこの経路の途中で捕集されるから、粉塵が換気口から外部に飛散するのを防止できる。また、騒音がこの経路を通過することで反射や回折により減衰されるので、騒音減衰性能を発揮して、騒音が換気口から外部に漏れるのを防止できる。したがって、簡易な構造で、粉塵の飛散、騒音の漏れ、および雨水の浸入を防止できる。   According to this invention, the clearance gap between the front-end | tip of a collar part and a roof becomes a ventilation opening, and the path | route from an opening to a ventilation opening turns into a return | turnback path | route. Therefore, since the collar portion is provided so as to cover the opening, it is possible to prevent rain from entering the inside from the opening. Accordingly, since a large amount of dust is collected in the middle of this route, it is possible to prevent the dust from scattering from the ventilation port to the outside. In addition, since noise is attenuated by reflection and diffraction by passing through this path, noise attenuation performance can be exhibited, and noise can be prevented from leaking from the vent. Therefore, it is possible to prevent dust scattering, noise leakage, and rainwater intrusion with a simple structure.

以下、本発明の一実施形態について、図面を参照しながら説明する。
図1は、本発明の一実施形態に係る仮設構造物1の縦断面図である。図2は、図1のI−I横断面図である。
仮設構造物1は、既存建物2の解体に用いられるものである。具体的には、図1中白抜き矢印で示すように、仮設構造物1を下降させながら、この仮設構造物1の内部空間3で重機4を駆動して解体作業を行う。
Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a longitudinal sectional view of a temporary structure 1 according to an embodiment of the present invention. 2 is a cross-sectional view taken along the line II of FIG.
The temporary structure 1 is used for dismantling the existing building 2. Specifically, as shown by the white arrow in FIG. 1, while the temporary structure 1 is lowered, the heavy machine 4 is driven in the internal space 3 of the temporary structure 1 to perform the disassembly work.

この仮設構造物1は、既存建物2の外周に沿って設けられた壁としての外周足場10と、この外周足場10に支持される屋根としての折板屋根20と、外周足場10の上部に設けられた換気部30と、を有する。
外周足場10は、複数段の枠組足場11と、この枠組足場11の外側を覆う防音パネル12と、を備える。
折板屋根20は、矩形状であり、外周足場10の枠組足場11の内側面まで延びている。これにより、折板屋根20の外縁と外周足場10の防音パネル12との間には、開口21が形成される。つまり、この開口21は、折板屋根20の外周に沿って形成されることになる。
The temporary structure 1 is provided on the outer periphery scaffold 10 as a wall provided along the outer periphery of the existing building 2, the folded plate roof 20 as a roof supported by the outer periphery scaffold 10, and the upper part of the outer periphery scaffold 10. Ventilating part 30.
The outer periphery scaffold 10 includes a multi-stage frame scaffold 11 and a soundproof panel 12 that covers the outside of the frame scaffold 11.
The folded plate roof 20 has a rectangular shape and extends to the inner surface of the frame scaffold 11 of the outer periphery scaffold 10. Thereby, an opening 21 is formed between the outer edge of the folded plate roof 20 and the soundproof panel 12 of the outer periphery scaffold 10. That is, the opening 21 is formed along the outer periphery of the folded plate roof 20.

開口21は、間仕切り22により、給気エリア21Aと排気エリア21Bとに仕切られている。この給気エリア21Aは、折板屋根20の長辺の2箇所および短辺の1箇所に設けられており、残りの部分は、排気エリア21Bとなっている。なお、これら給気エリア21Aの位置については、特に限定されず、任意に設定されてよい。   The opening 21 is partitioned by a partition 22 into an air supply area 21A and an exhaust area 21B. The air supply area 21A is provided at two places on the long side and one place on the short side of the folded plate roof 20, and the remaining part is an exhaust area 21B. Note that the position of the air supply area 21A is not particularly limited, and may be set arbitrarily.

図3は、仮設構造物1の縦断面図である。
換気部30は、防音パネル12から折板屋根20の屋根面20Aよりも上方まで延びる延出部31と、この延出部31から略水平に内側に向かって延びて開口21を覆う庇部32と、この庇部32の先端から下方に延びる垂れ壁部33と、を備える。
FIG. 3 is a longitudinal sectional view of the temporary structure 1.
The ventilation part 30 extends from the soundproof panel 12 to the upper side of the roof surface 20A of the folded roof 20 and a flange part 32 extending from the extension part 31 substantially horizontally inward to cover the opening 21. And a hanging wall portion 33 extending downward from the tip of the flange portion 32.

折板屋根20の屋根面20Aのうち庇部32の直下には、立ち上がり部34が設けられる。ここで、垂れ壁部33と折板屋根20の屋根面20Aとの隙間を、換気口35とすると、この換気口35は、折板屋根20の中央部に向かって開放されている。   A rising portion 34 is provided immediately below the collar portion 32 in the roof surface 20A of the folded plate roof 20. Here, if a gap between the hanging wall portion 33 and the roof surface 20 </ b> A of the folded plate roof 20 is a ventilation port 35, the ventilation port 35 is opened toward the center of the folded plate roof 20.

これにより、開口21から換気口35に至る経路Sは、以下のようになる。すなわち、図3中矢印で示すように、開口21から上昇して庇部32に突き当たり、次に、この庇部32に沿って水平移動し、垂れ壁部33に突き当たって下降する。その後、屋根面20Aに沿って水平移動して、換気口35に至る。このように、開口21から換気口35に至るまで、二度折り返した経路となる。   Thereby, the path | route S from the opening 21 to the ventilation port 35 becomes as follows. That is, as shown by an arrow in FIG. 3, the lift rises from the opening 21 and hits the flange 32, then moves horizontally along the flange 32, hits the drooping wall 33 and descends. Then, it moves horizontally along the roof surface 20 </ b> A and reaches the ventilation opening 35. In this way, the path is folded twice from the opening 21 to the ventilation opening 35.

図4は、仮設構造物1の給気エリア21Aの縦断面図である。図5は、給気エリア21Aの斜視図である。
給気エリア21Aでは、外周足場10の枠組足場11には、開口21から内部空間3の重機4付近まで延びる給気装置40が取り付けられている。この開口21は、塞ぎ材23で塞がれている。
FIG. 4 is a longitudinal sectional view of the air supply area 21 </ b> A of the temporary structure 1. FIG. 5 is a perspective view of the air supply area 21A.
In the air supply area 21 </ b> A, the air supply device 40 extending from the opening 21 to the vicinity of the heavy machine 4 in the internal space 3 is attached to the frame scaffold 11 of the outer periphery scaffold 10. The opening 21 is closed with a closing material 23.

給気装置40は、開口21付近の空気を吸い込んで、重機4の近傍に吹き出すものである。この給気装置40は、送風機41と、この送風機41から開口21に至る一次側ダクト42と、送風機41から重機4の近傍に至るフレキシブルダクトである二次側ダクト43と、を備える。一次側ダクト42の先端は、開口21から上方に突出している。   The air supply device 40 sucks air in the vicinity of the opening 21 and blows it out in the vicinity of the heavy machine 4. The air supply device 40 includes a blower 41, a primary duct 42 that extends from the blower 41 to the opening 21, and a secondary duct 43 that is a flexible duct that extends from the blower 41 to the vicinity of the heavy machine 4. The distal end of the primary duct 42 protrudes upward from the opening 21.

本実施形態によれば、以下のような効果がある。
(1)開口21を覆うように庇部32を設け、この庇部32の先端に垂れ壁部33を設けたので、開口21から換気口35までの経路Sは、二度折り返した経路となる。
よって、図6に示すように、雨Aが換気口35に降り注いでも、この雨Aが開口21から内部空間3に浸入するのを防止できる。また、開口21の内側に立ち上がり部34を設けたので、雨水が屋根面を流れて開口から内部空間に浸入するのを防止できる。また、図6に示すように、粉塵Bの多くが経路の途中の枠組足場11上に捕集されるから、粉塵が換気口35から外部に飛散するのを防止できる。また、図7に示すように、騒音Cがこの経路を通過することで反射や回折により減衰されるので、騒音減衰性能を発揮して、騒音が換気口35から外部に漏れるのを防止できる。
したがって、簡易な構造で、粉塵の飛散、騒音の漏れ、および雨水の浸入を防止できる。
According to this embodiment, there are the following effects.
(1) Since the collar part 32 is provided so as to cover the opening 21 and the hanging wall part 33 is provided at the tip of the collar part 32, the path S from the opening 21 to the ventilation port 35 is a path folded twice. .
Therefore, as shown in FIG. 6, even if rain A pours into the ventilation opening 35, this rain A can be prevented from entering the internal space 3 from the opening 21. Further, since the rising portion 34 is provided inside the opening 21, it is possible to prevent rainwater from flowing through the roof surface and entering the internal space from the opening. Moreover, as shown in FIG. 6, since most of the dust B is collected on the frame scaffold 11 in the middle of the path, it is possible to prevent the dust from scattering from the ventilation port 35 to the outside. Further, as shown in FIG. 7, since the noise C is attenuated by reflection and diffraction by passing through this path, the noise attenuation performance can be exhibited and the noise can be prevented from leaking to the outside from the ventilation port 35.
Therefore, it is possible to prevent dust scattering, noise leakage, and rainwater intrusion with a simple structure.

(3)換気口35が折板屋根20の内側に向いているので、換気口35から騒音が漏れる方向あるいは粉塵が飛散する方向は、折板屋根20の内側つまり近隣とは反対方向となる。したがって、騒音や粉塵が近隣に到達するのをより確実に防止できる。   (3) Since the ventilation port 35 faces the inside of the folded plate roof 20, the direction in which noise leaks from the ventilation port 35 or the direction in which dust scatters is opposite to the inside of the folded plate roof 20, that is, the neighborhood. Accordingly, it is possible to more reliably prevent noise and dust from reaching the vicinity.

(4)開口21および換気口35を防音パネル12の上端つまり仮設構造物1の最も高い位置に設けた。よって、外部の風の強弱によらず、内部空間上部の高温な空気と外気との温度差による自然換気が行われるから、仮設構造物1の内部空間で重機を駆動しても、これら重機や設備機器からの排熱や排気ガスを自然に排出できる。   (4) The opening 21 and the ventilation port 35 are provided at the upper end of the soundproof panel 12, that is, at the highest position of the temporary structure 1. Therefore, natural ventilation is performed by the temperature difference between the hot air in the upper part of the internal space and the outside air regardless of the strength of the external wind. Even if the heavy machinery is driven in the internal space of the temporary structure 1, these heavy machinery and Exhaust heat and exhaust gas from equipment can be discharged naturally.

(5)枠組足場11に、給気エリア21Aの開口21から内部空間3に空気を送る給気装置40を取り付けた。
内部空間3において溶接作業や重機作業を行う場合、排気ガスが局所的に発生するため、給気が必要となることが多いが、この給気装置40により、このような局所的に発生した排気ガスを確実に外部に排出できる。
(5) The air supply device 40 that sends air to the internal space 3 from the opening 21 of the air supply area 21A is attached to the frame scaffold 11.
When performing welding work or heavy machinery work in the internal space 3, exhaust gas is locally generated, so air supply is often required. However, the air supply device 40 causes such locally generated exhaust gas. Gas can be reliably discharged outside.

(6)給気装置40の一次側ダクト42を開口21まで延ばしたので、給気装置40についても、折り返し構造による騒音減衰機能および雨水浸入防止機能が有効に機能する。したがって、給気装置40の一次側ダクト42内に消音装置を設ける必要がなくなり、コストを低減できる。   (6) Since the primary duct 42 of the air supply device 40 is extended to the opening 21, the noise attenuation function and the rainwater intrusion prevention function by the folded structure also function effectively for the air supply device 40. Therefore, it is not necessary to provide a silencer in the primary duct 42 of the air supply device 40, and the cost can be reduced.

(7)枠組足場11に給気装置40を設置したので、給気装置40を枠組足場11と一体に移動できるから、給気装置40を内部空間3の床面に設置する必要がなく、給気装置40の盛替作業の手間を軽減できる。   (7) Since the air supply device 40 is installed in the frame scaffold 11, the air supply device 40 can be moved integrally with the frame scaffold 11, so there is no need to install the air supply device 40 on the floor surface of the internal space 3. It is possible to reduce the trouble of refilling the air device 40.

(8)二次側ダクト43をフレキシブルダクトとしたので、局所的に新鮮空気が必要な箇所については、この二次側ダクトを所望の位置まで延ばして対応できる。   (8) Since the secondary duct 43 is a flexible duct, the secondary duct can be extended to a desired position for a place where fresh air is locally needed.

(9)折板屋根20を外周足場10の枠組足場11の内壁面までとしたので、折板屋根20を切断加工して開口を形成する必要がなく、施工手間を軽減できる。   (9) Since the folded plate roof 20 extends to the inner wall surface of the frame scaffold 11 of the outer periphery scaffolding 10, it is not necessary to cut the folded plate roof 20 to form an opening, and the construction labor can be reduced.

なお、本発明は前記実施形態に限定されるものではなく、本発明の目的を達成できる範囲での変形、改良等は本発明に含まれるものである。
例えば、本実施形態では、開口21から換気口35までの経路Sを二度折り返した経路としたが、これに限らず、一度だけ折り返した経路としてもよいし、三度以上折り返した経路としてもよい。
It should be noted that the present invention is not limited to the above-described embodiment, and modifications, improvements, etc. within a scope that can achieve the object of the present invention are included in the present invention.
For example, in the present embodiment, the route S from the opening 21 to the ventilation opening 35 is a route that is folded twice, but is not limited thereto, and may be a route that is folded only once, or may be a route that is folded three times or more. Good.
