Description

  The present invention relates to a soundproof enclosure installation method and apparatus for installing a soundproof enclosure around a device that generates noise.

  For example, when a device that generates noise, such as a gas turbine power generator, is installed at an equipment installation site, the above gas is generally placed on the upper surface of a common base plate (base) made of H-section steel or the like installed on the foundation side. Equipment such as gas turbines, reducers, generators, etc. that constitute the turbine power generator are installed, and a rectangular parallelepiped soundproof enclosure that is open at the bottom covers the gas turbines, reducers, generators, etc. Installed to reduce the noise emitted to the outside.

  As a conventional method of installing this type of soundproof enclosure, as schematically shown in FIG. 5 as an example, the common base plate 1 and the gas of the gas turbine power generator installed on the upper surface of the common base plate 1 are used. The soundproof enclosure 3 is assembled by field work at the actual installation site so that the entire equipment (not shown) such as a turbine, a speed reducer, and a generator is covered with the soundproof enclosure 3 from above. In this state, the soundproof enclosure 3 is supported and installed on the floor of the foundation 2 in such a state.

  Further, as another method for installing the soundproof enclosure, as shown in FIGS. 6 and 7 (a) and (b), in the assembly plant, the gas turbine of the gas turbine power generation device on the common base plate 1, the deceleration Equipment (not shown) such as a machine and a generator is installed, and a panel material 7 is attached to a skeletal structure formed by a beam material 5 and a column material 6 made of a hollow square pipe, and the same as the common base plate 1 After the soundproof enclosure 4 having the planar shape is manufactured, and further, the soundproof enclosure 4 is disposed at the assembly plant so as to cover various devices such as the gas turbine installed on the common base plate 1 from above. A plurality of locations at the lower end of the soundproof enclosure 4 are attached to the upper side surface of the outer peripheral edge of the common base plate 1 via a vibration-proof support member 8 having a vibration-proof rubber 9, so that the common base plate 1 and the soundproof enclosure 4 to be integrated Then, the common base plate 1 and the soundproof enclosure 4 previously integrated in the assembly factory in this way are transported together to the equipment installation place using a vehicle or the like, and the base plate 1 is fixed on the foundation 2. A soundproof enclosure 4 is also proposed.

  Further, when the common base plate 1 and the soundproof enclosure 4 attached to the common base plate 1 via the vibration isolation support member 8 are integrated and transported, the soundproof enclosure 4 is shaken and the vibration isolation support member 8 In order to prevent the vibration-proof rubber 9 from being burdened, it is also proposed that the soundproof enclosure 4 is firmly fixed to the common base plate 1 via a transport bracket (not shown) during transport. (For example, refer to Patent Document 1).

JP 2003-138909 A

  However, as in the method shown in FIG. 5 described in Patent Document 1, the common base plate 1 and the entire device thereon are assembled in the soundproof enclosure 3 in the field work, and the device is assembled. When the lower end of the soundproof enclosure 3 is fixed and installed on the foundation 2 around the common base plate 1 fixed at the installation site, the assembly work is performed in an environment that is not equipped as compared with the assembly factory. There is a problem that quality and cost are problematic, and that the assembling work of the soundproof enclosure 3 requires a lot of labor and time, resulting in a long construction period.

  On the other hand, as shown in FIG. 6 and FIG. 7 (A) (B), the soundproof enclosure 4 is arranged on the common base plate 1 at the assembly factory, and the soundproof enclosure 4 is provided with the vibration-proof rubber 9. After mounting and supporting on the common base plate 1 via the vibration isolation support member 8, the common base plate 1 and the soundproof enclosure 4 are integrated and transported to the equipment installation site, and the common base plate 1 is mounted on the foundation 2. In the case of the installation method, the soundproof enclosure 4 can be manufactured at a well-equipped assembly plant, so that the quality and cost problems that have arisen when assembling the soundproof enclosure 3 at the site construction as described above are eliminated. This can be solved and the construction period can be shortened. However, even if the anti-vibration support member 8 including the anti-vibration rubber 9 is interposed, the solid vibration transmitted from the common base plate 1 through the anti-vibration support member 8 to the soundproof enclosure 4 is completely blocked. Is difficult. For this reason, it is possible to satisfy a noise guarantee value of about 85 dB (noise level) at a measurement of 1 m as conventionally required when installing a gas turbine power generation device, but recently it has been increasingly required. The actual situation is that it is difficult to satisfy a noise guarantee value of 75 dB (noise level) at 1 meter of measurement.

  In the case where the soundproof enclosure 4 is installed on the common base plate 1 described in Patent Document 1, the outer surface of the common base plate 1 cannot be covered with the soundproof enclosure 4. Is exposed to the outside, and reverberation is generated by the hollow portion of the H-shaped steel due to the vibration of the common base plate 1. Therefore, it is necessary to provide the sound insulating material 10 and to cover the sound insulating material 10 with the cover 11.

  In Patent Document 1, when the common base plate 1 and the soundproof enclosure 4 attached to the common base plate 1 via the vibration isolation support member 8 are integrally transported, the soundproof enclosure is provided to the common base plate 1. Although the idea of firmly fixing 4 is shown, this is because the soundproof enclosure 4 is shaken at the time of conveyance and the vibrationproof support member 8 interposed between the soundproof enclosure 4 and the common base plate 1 is prevented. In order to prevent the vibration rubber 9 from being burdened, the idea of completely separating the soundproof enclosure 4 from the common base plate 1 after the common base plate 1 is installed at the required installation location is completely shown. It is not even suggested.

  Therefore, the present invention can reduce the time and labor required for installing the soundproof enclosure, shorten the work period, and further improve the soundproof performance of the soundproof enclosure. Is to provide.

In order to solve the above-mentioned problem, the present invention allows the above- mentioned base plate to hold a soundproof enclosure that surrounds the base plate and covers the base plate and the entire apparatus installed on the top surface of the base plate . the soundproof enclosure transported to equipment installation site on SL base plate and one body, then, as installed by fixing each 該台plate and the soundproof enclosure basic side, the該台plate and the soundproof enclosure the temporary fixing and installation method of soundproof enclosure to insulate after the transportation, a soundproof enclosure so as to cover the entire equipment located on the upper surface of 該台plate and the base plate surrounds the periphery of the base plate to the upper Symbol bedplate to, a-proof sound enclosure transported to equipment installation site on the base plate and one body, then, as installed by fixing each 該台plate and the soundproof enclosure underlying side of the soundproof enclosure Temporarily fixed to the serial base plate and installation method soundproof enclosure for insulating the該台plate and the soundproof enclosure to release after the transfer.

Next, a conveyance fixing jig 17 is interposed between the common base plate 1 and the soundproof enclosure 12, and the soundproof enclosure 12 is temporarily fixed to the common base plate 1 so that they are integrated. This temporary fixing is performed by attaching one end side of the conveyance fixing jig 17 to the soundproof enclosure 12 with the bolt 20 and attaching the other end side to the common base plate 1 with the bolt 21. At this time, since there is a gap between the common base plate 1 and the soundproof enclosure 12 in which an operator can enter, the temporary fixing operation can be easily performed.

  Thereafter, as shown by a two-dot chain line in FIG. 1 (a), the suspension rope 25a from the conveying device 25 such as a crane is hung on the base plate hanging bracket 22 projected outside through the opening 24 of the soundproof enclosure 12. The common base plate 1 and the soundproof enclosure 12 are lifted up and loaded on a vehicle (not shown) as they are and transported to a position near the installation location of the gas turbine power generator, and then the common base plate 1 and the soundproof enclosure 12 are suspended. It is lowered from the vehicle and placed on the foundation 2 as a predetermined installation location.

  Next, the soundproof enclosure 12 is installed by fixing the common base plate 1 and the soundproof enclosure 12 to the foundation 2, and then the soundproof enclosure 12 is passed from the foundation 2 through the common base plate 1 and the transport fixture 17. In order to cut off the propagation of vibration to the soundproof enclosure 12, the transfer fixtures 17 temporarily fixed to the soundproof enclosure 12 are all removed to insulate the common base plate 1 from the soundproof enclosure 12. To complete. At this time, the temporary fixing is removed by removing the bolts 20 and 21 and removing the transport fixing jig 17 from the soundproof enclosure 12 and the common base plate 1 as shown in FIG. When loosening the bolt 20 that attaches the transport fixture 17 to the soundproof enclosure 12, for example, a receiving member 26 having a required thickness dimension is arranged below the soundproof enclosure 12. By providing it, the load of the soundproof enclosure 12 acting on the bolt 20 may be removed. As a result, the soundproof enclosure 12 is completely separated from the common base plate 1 and completely covers the various devices of the gas turbine power generator provided on the common base plate 1 together with the common base plate 1. It will be arranged on the foundation 2 of the installation place in the state.

  Further, the base plate hanging bracket 22 attached to the common base plate 1 is removed as shown in FIG. 2C by removing the bolt 23, and then the opening 24 of the soundproof enclosure 12 is closed with a lid 24a. , Make sure that noise does not leak outside. The common base plate 1 and the soundproof enclosure 12 may be fixed to the foundation 2 after the transfer fixture 17 and the base plate hanging bracket 22 are removed.

Since it can be transported and installed on the foundation 2 at the site, the quality of the soundproof enclosure 12 can be improved. Therefore, for example, when equipment such as a gas turbine, a speed reducer, and a generator of a gas turbine power generator is provided on the common base plate 1 as described above, a pipe (not shown) that supports the common base plate 1 is shown. Even if it is arranged so as to penetrate the soundproof enclosure 12 in the inner and outer directions, the pipe can be arranged in advance at a predetermined position of the soundproof enclosure 12 in the assembly factory or the like. Moreover, the soundproof enclosure 12 installed at the equipment installation site is completely separated from the common base plate 1 with a required gap, and can transmit solid vibration from the common base plate 1, and Since the gas turbine power generator is completely covered with the common base plate 1 on the foundation 2, the soundproof performance can be enhanced. In addition, since the high-quality soundproof enclosure 12 can be manufactured, the panel material 15 to be used is made thinner than the conventional soundproof enclosure 4 as shown in FIGS. However, sufficient soundproof performance can be obtained. Thus, in the soundproof enclosure 12 installed by the installation method of the present invention, 75 dB at a measurement of 1 m, which was difficult to achieve with the conventional soundproof enclosure 4 as shown in FIGS. It becomes possible to satisfy the noise guarantee value of (noise level).

  Further, since the soundproof enclosure 12 is directly installed on the foundation 2, the soundproof enclosure 4 and the common base plate 1 shown in FIG. 6 and FIGS. There is no need for a member that deteriorates with time like the vibration isolating rubber 9 of the intervening vibration isolating support member 8, and it is possible to reduce the labor required for maintenance of the soundproof enclosure 4.
