Inverse construction method for spoke type cable-supported grid structure
The invention discloses an inverse construction method for a spoke type cable-supported grid structure. The inverse construction method comprises the following implementation steps that S1, stiff steel-reinforced concrete columns are firstly mounted according to the structural design of a stadium, and then elastic supports are mounted after the stiff steel-reinforced concrete columns are arranged and mounted; S2, a box type outer compression ring beam is installed on the installation basis of the above step; S3, supporting jig frames are installed, specifically, the supporting jig frames are installed at the outer ends of radial main beams of the cable-supported grid structure and below the connecting points of radial cables and inner ring cables at intervals of two spans, and the supporting jig frames are fixed through cable wind ropes; and S4, radial cables at the supporting jig frame positions are installed, the radial cables at the supporting jig frame positions are hoisted, one ends of the radial cables are connected with lug plate plug pins on the box type outer compression ring beams, and the other ends of the radial cables are temporarily connected with the supporting jig frames. According to the method, inhaul cables are firstly installed and tensioned, the inhaul cables in a initial stress state are used as supports, then roof rigid grids are installed, and inverse construction of the spoke type cable-supported grid structure is achieved.
本发明公开了一种车幅式索承网格结构逆作施工方法，包括以下实施步骤：步骤S1：根据体育场结构设计首先安装劲性钢骨混凝土柱，劲性钢骨混凝土柱设置安装之后再进行弹性支座的安装；步骤S2：在上述步骤的安装基础上进行安装箱型外压环梁；步骤S3：安装支撑胎架，在索承网格结构径向主梁外端，径向索与内环索连接点下，隔两跨安装支撑胎架，用道缆风绳对支撑胎架进行固定；步骤S4：安装支撑胎架部位径向索，吊装设置支撑胎架部位的径向索，径向索一端与箱型外压环梁上的耳板插销连接，另一端与支撑胎架临时连接。本发明先安装拉索并进行张拉，以初始应力态的拉索为支撑，后安装屋面刚性网格，实现车幅式索承网格结构逆作施工。
