筐体４を押付けることにより騒音測定を行っていた。That is, as shown in FIG. 1a, after constructing a large number of working floors 3 along the outer peripheral wall surface of a building 2 such as a factory that houses a housing 1 for noise-generating equipment, 1st
As shown in the figure, the noise measurement is carried out by a pair of working tools M riding on the housing housing 4 of the noise measuring device and pressing the housing 4 against the outer wall of the building 2 while supporting the housing 4 with their hands. was.
なお、作業床３は地上から順次組上げられる場合もある
が、第１図ａのように隣接する建屋５が建屋２に近接し
て設置されている場合には隣接建屋５の屋根上から作業
床３を組上げる場合もあった。The work floor 3 may be assembled sequentially from the ground, but if the adjacent building 5 is installed close to the building 2 as shown in Figure 1a, the work floor 3 may be assembled from the roof of the adjacent building 5. In some cases, 3 were assembled.
このような従来の騒音測定装置による騒音測定が非能率
であることは明らかである。It is clear that noise measurement using such conventional noise measurement devices is inefficient.
それ故、本発明の目的は従来の１騒音測定装置による非
能率を排し、能率的に建築物等からの発生騒音を測定で
きる改良された騒音測定装置を提供することにある。SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide an improved noise measuring device that eliminates the inefficiency of the conventional single noise measuring device and can efficiently measure noise generated from buildings, etc.

昇降動され、騒音測定が無人で行われる。According to the improved noise measuring device of the present invention, as shown in FIG. 2, the storage casing 4 of the noise measuring device is pressed against the outer wall surface via the arm 10A by the guide rope G stretched over the outer wall surface. At the same time, it is automatically moved up and down the outer wall surface of the building 2 by a hoist 6 placed on the ground or on the roof of an adjacent building 5, a rope R, and a fixed pulley 7 suspended from the roof of the building 2. , noise measurements are performed unattended.
第２図に於て、８は建屋２の屋根もしくは壁面頂部に着
脱可能に取付けられたブラケット、７はブラケット８に
吊下された固定滑車、９は地上もしくは隣接建設５の屋
根上に置かれた固定滑車、を示す。In Fig. 2, 8 is a bracket removably attached to the roof or top of the wall of building 2, 7 is a fixed pulley suspended from bracket 8, and 9 is a bracket placed on the ground or on the roof of adjacent construction 5. A fixed pulley is shown.
騒音測定機器の収納筐体４を昇降用ロープＨに支持させ
るために筐体４を把持するフレーム１０が第３図及び第
４図に示すように筐体４を包囲しており、このフレーム
１０には建屋２の外壁面上を転動するローラ１１が筐体
４の前面側に取付けられている。As shown in FIGS. 3 and 4, a frame 10 that grips the housing 4 of the noise measuring equipment so that the housing 4 is supported by the lifting rope H surrounds the housing 4. A roller 11 that rolls on the outer wall surface of the building 2 is attached to the front side of the housing 4.
フレーム１０にはまた、後方へ（つまり、ローラ１１の
取付位置に対して逆向きに）突出する一対の腕１０Ａが
設けられており、この腕１０Ａの先端にはそれぞれ一個
ずつの滑車１０Ｂが回転可能に取付けられている。The frame 10 is also provided with a pair of arms 10A that protrude rearward (that is, in the opposite direction to the mounting position of the rollers 11), and a pulley 10B rotates at the tip of each arm 10A. installed as possible.
腕１０Ａ及び滑車１０Ｂはローラ１１を建屋２の外壁面
に圧接させるだめのもので、建屋２の外壁の頂部と下部

プＧの中間部が滑車１０Ｂにかけられることにより、滑
車１０Ｂ及び腕１０Ａを介してローラ１１が建屋２の外
壁面に圧接されるようになっている。The arm 10A and the pulley 10B are used to press the roller 11 against the outer wall surface of the building 2, and are located in the middle of the guide rope G, which is stretched vertically with both ends attached to the top and bottom of the outer wall of the building 2. The roller 11 is brought into pressure contact with the outer wall surface of the building 2 via the pulley 10B and the arm 10A.
フレーム１０に周囲を把持された状態に於て筐体４の前
面は二個のローラ１１の周面を結ぶ線とほぼ一致し、従
ってローラ１１が建屋２の外壁面に圧接された状態では
筐体４の前面は建屋２の外壁面に極めて近接した位置に
位置決めされる。When the periphery of the casing 4 is gripped by the frame 10, the front surface of the casing 4 almost coincides with the line connecting the circumferential surfaces of the two rollers 11. Therefore, when the roller 11 is pressed against the outer wall surface of the building 2, the front surface of the casing 4 The front surface of the body 4 is positioned very close to the outer wall surface of the building 2.
従。って、筐体４は、外壁面に安定して位置決めされ、
精度の良い騒音測定を行うことができる。Follow. Therefore, the housing 4 is stably positioned on the outer wall surface,
Accurate noise measurements can be performed.

の間に騒音測定が行われる。With the above configuration, when the hoisting machine 6 installed on the ground or on the roof of the adjacent building 5 is operated, the housing 4 for the noise measuring equipment is moved along the guide rope G to the outer wall of the building 2. It is lifted and lowered unmanned along the guide rope G while being pressed, and noise measurements are performed during this time.
この結果、作業員による危険な高所における騒音測定作
業を々くすことかできる。As a result, it is possible to reduce noise measurement work performed by workers at dangerous high places.
