Oblique beam for grandstand of stadium and construction process for oblique beam

Abstract

The invention belongs to the technical field of construction for oblique beams for grandstands of stadiums, and particularly relates to an oblique beam for a grandstand of a stadium and a construction process for the oblique beam. The oblique beam for the grandstand of the stadium is characterized by mainly comprising an oblique beam body; the lower end of the oblique beam body is connected with the upper end of a first-layer column through casting; the middle and the upper end of the oblique beam body are connected with a Y-shaped column through casting; two sides of the oblique beam body and the oblique beam body are provided with lugs through casting; the lugs are higher than the upper surface of the oblique beam body. The oblique beam can ensure the visual effect of upper-layer spectators under the condition of a certain inclination angle.

Description

technical field [0001] The invention belongs to the technical field of construction technology for a slanted beam of a stadium stand, and in particular relates to a slanted beam of a stadium stand and a construction process thereof. Background technique [0002] The 15,000-seat main stadium project of Wuhan Optics Valley International Tennis Center is a "bowl-shaped" stadium composed of 32 Y-shaped columns supporting the inclined beams of the stands. The engineering structure is relatively complicated. Because the stands are in the form of steps, there are many forms of lower supporting structures. The supporting structure of the tennis hall stands in this project is a cantilevered large inclined beam on a Y-shaped column. The stand is high from the ground and has a large span. The design size of inclined beam section is large. The oblique beam itself is an oblique member, and the overweight oblique member in space will generate a large horizontal thrust due to its own weig...

AI Technical Summary

Problems solved by technology

However, this construction technology will simultaneously construct the lugs and the inclined beams, which reduces the construction process; this method carries out segmental concrete pouring on the inclined beams, which effectively solves the problem of excessive horizontal thrust of the inclined beams; Vibrating the holes shortens the time for concrete pouring of inclined beams, solves the difficulty of concrete accumulation at the bottom of concrete pouring of inclined beams, avoids laitance on the surface of inclined beams, ensures the structural quality of inclined beams, and improves the overall quality of concrete sensory
