Description

TECHNICAL FIELD

[0001] The utility model relates to the field of building, concretely relates to a membrane ceiling joint for stadium. BACKGROUND

[0002] The composite membrane of the stadium solves the huge visual space requirement that cannot be realized by traditional reinforced concrete, steel structure and the like because of its light weight. Meanwhile, the composite membrane has good flame retardant and high temperature resistant properties, and strong artistic plasticity, which can meet the various special-shaped and simple modeling requirements of architects. In recent years, with the large number of construction of steel cable structure stadiums, the composite membrane technology is becoming mature. The composite membrane in the prior art only plays a building decoration role by being attached to the steel structure and the like and being tensioned to form a special-shaped surface, and the membrane surface is flat after tensioning and is not suitable for secondary processing. The use of the composite membrane for the ceiling of the stadium can reduce the roof load, and can also meet the decorative and aesthetic effect of the daily stadium, and the stadium can be used for holding concerts, artistic performances and the like during non-match time. However, the composite membrane of the existing stadium cannot meet the sound insulation requirement, and the artistic performance often needs to be modified in terms of sound and lamps and lanterns on the top according to the performance content. The composite membrane that is installed once cannot meet the modification requirement of the ceiling for the artistic performance. For example, the stadium based on the combination structure of the hyperstatic ring truss and the cable dome disclosed in Chinese utility model patent CN207597594U includes a peripheral hyperstatic ring truss structure and a cable dome structure. The peripheral hyperstatic ring truss structure includes bearing piers, bearing columns, struts and truss bars. The cable dome structure includes upper chord ridge cables, lower chord inclined cables, outer ring beams, inner ring beams and compression bars. The peripheral hyperstatic ring truss structure is fixed to the ground to provide necessary constraint force to balance the huge tension generated by the roof of the cable dome structure. The cable dome structure forms a self-stress spatial structure system through the upper chord ridge cables, the lower chord inclined cables and the compression bars. The outer ends of the upper chord ridge cables and the lower chord inclined cables in the peripheral cable dome structure are fixed to the peripheral hyperstatic ring truss structure, and the outer ring beams, the inner ring beams and the compression bars in the cable dome structure fix the shape of the overall structure. For another example, the rigid roof combined type tension dome structure disclosed in Chinese utility model patent CN206928432U includes an external cable truss structure and an internal cable dome structure. The external cable truss structure includes an outer ring, cable truss ridge cables, cable truss upper ring cables, cable truss lower ring cables and cable truss inclined cables. The internal cable dome structure includes an inner pull ring and at least one ring of ring components arranged between the inner pull ring and the external cable truss structure. In the foregoing two patents, the composite membrane is once formed and cannot be secondarily installed after being installed on the top of the stadium. The composite membrane cannot be soundproofed and cannot be secondarily installed with sound and lamps and lanterns, so that the modification requirement of the artistic performance cannot be met.

[0003] Therefore, the utility model provides a stadium with membrane ceiling node, through setting up sound absorption cotton on the membrane surface to guarantee the sound effect and sound insulation function of the artistic performance, through setting up bearing part and membrane cover to add sound equipment, lamps and lanterns and other stage utensils load, so as to meet the reconstruction demand of artistic performance, simultaneously, after the whole composite membrane installation is completed, through bearing part directly load addition, need not to carry out on -the -spot secondary welding and other operations.
