Wooden floors for theater stages, but so far there is no unified norm or standard for builders to refer to, and different places and construction units have different practices. In the management of the entire theater construction project, the wooden floor for the stage can be regarded as the smallest sub-project, which often fails to receive sufficient attention from managers, or is omitted because other important project types need to be managed and coordinated. For example, in a certain theater in a certain place, in the general contract bidding, the stage wooden floor is included in the bidding, and there is no special technical requirement for the stage wooden floor in the bidding documents, and the winning bidder is based on the ordinary civil wooden floor. During the construction, it was found that the requirements of the stage wooden floor are quite different from that of the ordinary household wooden floor. At this time, the low quotation and high quality requirements for the stage floor make the winning bidder unacceptable and cause a fight; in addition, for the wood floor for theater stage process The unfamiliarity can not guarantee the quality, which has a great impact on the construction of the project.
Technical characteristics of wood floors for theatre stages
Different performance forms have different requirements for the stage floor, and even different dances have different requirements for the floor. For example, ballet should be non-slip, barefoot modern dance should be smooth, tap dance should not be too slippery but flexible, and rhythmic gymnastics uses a special elastic carpet and so on. As a comprehensive local theater, it should be considered from the perspectives of versatility, universality, stability, and practicality. exercise needs. Dramas and operas have no special requirements on the floor. In view of these characteristics of stage performances, the stage wooden floor must meet the following three aspects in terms of professional functions
(1) The performance (sports) function should meet the requirements of various performances as much as possible, especially dance, acrobatics and other sporty performances. Avoid excessive energy consumption by actors and maximize their acting skills. Therefore, the floor must have a certain elasticity, and the two indicators of vibration deformation and motion deformation comprehensively explain this movement performance. Of course, the wooden floor itself has good natural elasticity.
(2) Safety function
In order to avoid the injury of the actors when they are exercising on the stage, the floor is required to have a certain vibration absorption rate to fully absorb the impact on the body when jumping and falling, reduce muscle fatigue, protect the joints and ligaments of the legs and feet, and try to avoid stage performances. The most common ankle injury. At the same time, the floor surface is required to have a suitable friction coefficient,If it is too slippery or too astringent, it is easy to fall, and it will also increase the load on the legs, which can easily cause fatigue and cause injury.
(3) Technical function
The load-bearing load and firmness of the wooden floor for the theater stage must meet the requirements of various performances. A large number of sets, props, and equipment are transported on the stage. Requirements for the load-bearing load of wooden floors. The rolling load is a specific indicator to measure this performance. Actors performing on the stage (mainly refers to movements with a large amount of exercise) have similar requirements to the floor as athletes have on the basketball court. We can learn from the relevant standards for sports wooden floors. At present, the Technical Committee of Sports Flooring (OZST) quantifies the technical indicators, adopts the provisions of Chapter 2 of the German D IN 18032 standard, and makes detailed regulations on the technical requirements of sports wood floors. This standard is also used for sports wood floors in my country. . It is divided into 5 parts. It is worth noting that although it is close, the specific indicators are definitely different. As for how much is suitable for the stage, it remains to be tested and explored by relevant experts.
