Introduction of each department

Concert Hall

The concert hall of Hefei Grand Theater adopts the layout of classical rectangular concert hall, which provides a stable and guarantee basis for better sound quality. There are 975 seats in the concert hall, including 582 pool seats, including 51 VIP seats and 2 disabled seats in the front area. The concert hall adopts the long row method to save space, and the row spacing is 1.1 meters. The hall has a volume of 10000 cubic meters and can play organ.

The concert hall has an area of 184 square meters and 124 fixed chorus seats, which can provide more performances of three pipe bands. The side wall of the stage is inclined backward and downward, with diffusion treatment, reflecting as much sound energy as possible to the audience. The interior walls on both sides of the hall are designed to tilt downward, which not only improves the sound effect, but also makes the space effect of the hall more centripetal. A transparent reflector with diffusion treatment is arranged above the stage, which can coordinate with the reflection of the surrounding wall and achieve good acoustic effect.

There are four entrances and exits in the pool seat of the concert hall, two entrances and exits in the floor and eight entrances and exits in the box, two of which are shared with the pool seat. Each entrance and exit is equipped with a sound gate, and the interior of the sound gate is flat top and the wall is provided with strong sound absorption treatment.

Multifunction Room

The multi-function hall of Hefei Grand Theater is equipped with a lifting platform, and the stage can be flexibly changed according to the needs. view

The arrangement of seats and the rising height of seats can also be adjusted with the evolution of stage form. At the same time, seat storage space is set under each lifting platform to match the evolution of stage function. Through the combination of simple lifting platform configuration and seat platform, the theater can realize five main combination transformations, which can be used as flat hall, small theater, "convex" stage, "t" stage and central stage respectively. By making corresponding variable measures in acoustics, we can achieve the best acoustic effect of natural sound performance without using sound reinforcement system.

The multi-function hall is a plane hall

All the seats and trolleys are stored in the lifting platform. There are no seats in the auditorium. All kinds of sports activities, exhibitions and dances can be held in the hall.

The multi-function hall is a small theater

The lifting platform close to the fixed stage rises to the stage plane of 0.8m, which is flush with the fixed stage and is used as the stage. The rest of the lifting platforms are lowered to a certain height according to the requirements to form a ladder, which is used as the auditorium and a smooth entrance and exit channel for the audience. The theater can perform local opera, drama, drama, stage play, small concert, etc. When the sound reflecting board in the hall is lowered, it can meet the requirements of natural sound performance to achieve the best hearing effect.

Multi function hall as a "convex" stage: the lifting platform close to the fixed stage rises to 0.8m stage level, which is used as a stage, and the rest of the lifting platform rises to a certain height as required to form a ladder, which is used as an auditorium, and forms a smooth entrance and exit channel for the audience. As a large extended stage, the multi-function hall is convenient for actors to communicate with the audience.

As a "t" type stage, the multi-function hall:

The lifting platform close to the fixed stage rises to 0.8m stage level for stage use, and the other lifting platforms in each row rise to 0.4m level for auditorium. As a large extended stage, theater has a long extended stage, which can be used as fashion stage.

The multi-function hall is the center stage

The lift platform rises to 0.8 m level for stage use, and the rest of the lift platforms rise to 0.4 m level for auditorium. The Theater Center is the stage and the auditorium is around.

Opera Hall

The audience hall of Hefei opera house has 1515 seats and 1036 seats (with disabled seats and VIP seats). There are 6 entrances and exits in the pool seat, 2 entrances and exits in the VIP seat, and 4 entrances and exits in the building. All entrances and exits are located near the fire stairwell or elevator to facilitate arrival and evacuation. All entrances and exits are equipped with sound gates to avoid interference with the performance. The VIP lounge and special toilet are set behind the VIP seat, and the elevator leads directly to the underground garage. There is no intersection between the VIP streamline and the ordinary audience.

Stage mechanical system of Opera Hall

The stage of the Opera Hall is a "pin" shaped frame stage, with a fixed opening of 18m wide and 12m high, and a movable opening to adapt to different scale performances. The main abutment is 32.8m wide, 23.5m deep and 30m high. The stage is equipped with large-scale machinery, with lifting, rotating, moving and other functions to adapt to different requirements of the performance.

The orchestra pool is an open type, with a net area of 92.8m. It can be played by a large band composed of 120 people. The depth of the opening is 5m, and the front and rear parts of the orchestra can be lifted and lowered. When the small band is used, the depth of the opening can be reduced to about 2m. The lifting Orchestra pool can also be used as a vertical transport tool such as grand piano and seats, and can also be used as a stage to expand the performance area.

Energy saving design

sketch

Hefei Grand Theater is a national pilot demonstration project of building energy conservation. In the process of design and construction, it is carried out in strict accordance with the national standards for energy conservation design of public buildings. Its application of energy-saving technology is at the leading level in domestic theater construction.

First of all, double vacuum glass curtain wall will be used in the exterior wall of Hefei Grand Theater in the future to achieve the effect of heat insulation and energy saving. Secondly, the roof adopts thickened rock wool metal system to achieve good heat and sound insulation effect. During the visit, the reporter saw these thickened rock wool on the top floor and tried to light it with a lighter, but it couldn't be ignited. It seems that this material can not only keep heat and sound insulation, but also prevent fire.

The most striking thing is that the Grand Theater will be married to Swan Lake in the future. According to the engineers, the internal air conditioning system of the Grand Theater adopts the water source heat pump system. In the future, the natural water storage and heat storage function of Swan Lake will be used to save energy, which is one of the most advanced and environmentally friendly air conditioning methods at present. For Hefei citizens, what they are most concerned about is whether the interior of the Grand Theater will be comfortable in the future? It is understood that the Grand Theater will adopt the stage waste heat recovery system to recover a large amount of heat generated by the stage and lighting for the air dehumidification of the theater, so as to improve the air quality and increase the comfort; adopt the solar hot water system to solve the daily management and performance of the grand theater; adopt the solar photovoltaic system to effectively convert the solar energy into electricity
