Olympic Games table tennis namely very lofty requirements of air projects. Peking University Gymnasium was built specifically as the table tennis rivalries, so in the background of the stadium, the wind speed, lighting and other zones have rigid requirements. Peking University Gymnasium walls a light gray backdrop in full compliance with the requirements of table tennis, athletes can be in a comfortable visual context apt melodrama their competitive class.
According to the ITTF and the provisions of the pertinent design specifications, table tennis playing area of the wind speed ought be fewer than 0.2 m / sec. So, Peking University Gymnasium is how to more and more to international criteria? Designers in the design process using the built physical model measurement, the game hall the manifold ventilation delivery can be carried out reiterated forms of simulation to prophesy effects of its operation, effectively guiding the indoor ventilation distribution design, and in table tennis zone on both sides of the main stadium battlefield side by side to send back to the air conditioning system, both to assure the room has the right temperature, wind speed can also empower the stadium to meet international standards. Distributed intelligent lighting control system can be preset lighting scenes, relying on the petition requirements and easily make the appropriate switch lighting scenes, which seem to shirk lighting glare phenomenon. "Tony governance sub-Park" is a small courtyard Qing Dynasty architectural style. The designer said, ahead of, "Tony governance sub-Park" agenda into the venue of the planning area, the native intend was to this small yard as a whole broader shifted to a place to work. But access to packages and found this small courtyard appearance the six trees is this chapter of the Qing Dynasty gardens, one of the most archaic one bungeana extra than 100 years antique. In array to protect the age trees, the designer re-design, the stadium eastern from the east so namely the construction of Metro Line is closer, increasing the trouble of the project. Meanwhile, the design of the overall alteration venues, a lot of underground pipes had to docking,beijing travel service, the allowance also increased a lot.
Small construction site as the venue afterward to the west and the Millennium Park Governing beta sub-trees, on the construction site layout, civilian construction, environmental protection put forward a very high demand. Even so, the designers ascertain it very worth it, "After completion, everybody will watch first-class universities in China, the new Olympic Stadium and the people heritage of 100 years ago stand attach in harmony." The utilization of Olympic venues after the game pile up attention by people, Peking University Gymnasium during the design phase to converge on the issue. After the Olympics, Peking University Gymnasium Peking University Gymnasium will be converted to be table tennis,beijing city tour, handball, basket ball, badminton, volleyball, indohardly everccer competitions, but also for vocational exercising, students in physical schooling, performance and neatness of the location of gathering, Olympic venues after the Games 1 of the maximum malleable venues. Peking University Gymnasium is fully enclosed indoor stadium, project completion, the Olympic Games to be held ahead and after the three major multinational competitions: This annual 13 to 18 December of the Good Luck Beijing Table Tennis; afterward 8 to 20 August of the Olympic Games table tennis competition and the next 9 to 17 September the Paralympic table tennis competition.
Peking University Gymnasium in the maintenance of the framework is divided into inner and outer layers, outer floor of the spectators hall and the passageway wall with a considerable area of the real point of the skylight wall prologue. Between the internal and outer envelope formed Huanlang, sun chamber warm in winter play a role in the summer to play the character of ventilation and cooling to retention energy. Peking University Gymnasium steel roof truss with a prestressed steel shell. As construction moldings, roof architecture, the larger thrust of the substructure, substructure, deserving to space limitations, languid patronizing conditions, how to meet the architectural style, while also reducing the boost of the roof building on the base, a roof roof structural design of the difficulties. Through careful inquiry, using the seismic loosen of the ball bearing hinge sliding roof impulse,beijing one day tour, and prestressed cable to compensate by bearing stiffness after the loosen of the weakening of the roof. Ball bearing hinge sliding seismic simulation, beneath the roof of the earthquake, Prestressing simulation is the key issue.
Layer of the stadium is partial based aboard 2 sets of ground-source heat pump system. Buried are arranged aboard both sides of the building foundation in the north and south, the buried depth of 75 meters, set up 79 groups to the north side of pipe to cater chilly energy were 188KW/301KW; the south side of 42 teams set up to pipe to invest cold heat were 120KW/192KW. Adding antifreeze circulating pump cooling water through the allocation to the end of the two integral water source heat pump unit to control the water system to achieve two of 4 air-conditioning water system control features. Resulting in the use of economy, renewable energy, while greatly reducing the spend of the transformation behind the game. Large gymnasium roof used to siphon the main stadium roof drainage system, the recess of roof rainwater for the gravity system. Siphon system to collect rain water by seepage from underground wells and blind trench recharge, ground water and gravity rainwater collected in situ by the green behind ground infiltration and permeability. Buried rainwater runoff into the college storm sewer system.
Peking University Gymnasium in the swimming pool will be arranged upon the roof of solar vigor collection device, the heat used to lukewarm the circulating water swimming pond. The solar preheated water and then with water - water type heat exchanger beyond until the water approached the design temperature. Full use of solar vigor, to conserve energy. Solar energy: collector area by 300m2, the mean everyday accumulation of solar energy 2.4 million KJ. Distributed Intelligent Lighting Control System North Table Tennis Hall warm-up games, the main stadium and swimming pond, lighting control, lighting control systems with dispensed comprehension. Which can be preset lighting scenes, according to different use, broadcast, etc., can accessible make the proper alternate lighting scenes; of the intelligent lighting control appliance to control alternatively get status information divide, effortless to administer upkeep and troubleshooting.
