Embodiment Construction

[0035] With the construction method described in the present invention, the construction of the station house cover of the Beijing-Tianjin intercity Yujiabao Station has been completed. The specific description will be given below.

[0036]The design shape of the roof is a single-layer reticulated shell steel structure, which has a shell-shaped hyperboloid formed by cross-braiding 36 clockwise and 36 counterclockwise spatial spiral box-section rods, and its planar design size is 143m×80m, the design height is 25.8m, without any vertical support inside. Below the roof is the waiting hall on the first floor and the track area on the second floor. The height of the waiting hall and the track area are both 10 meters.

[0037] During construction, the single-layer reticulated shell steel structure is sequentially divided from top to bottom as follows: figure 1 , 2 The lifting area 1, interlocking area 3, and loose patching area 2 shown in the three areas are under construction, ...

Abstract

The invention provides a construction method of a large-scan single-layer latticed shell steel structure. According to the construction method, during construction, the single-layer latticed shell steel structure is sequentially divided into three areas, namely a lifting area, an inlaying area and a splicing area from top to bottom, wherein rod pieces in the lifting area are installed on a bed-jig group of the lifting area lower than a design height, and are entirely lifted after installation. Therefore, the installation precision and quality can be ensured, and the construction security is improved. The construction method avoids the problems in the traditional bed-jig support method that a mass of bed-jig need to be erected and large-tonnage hoisting equipment needs to be used, and the stability of the bed-jigs is difficult to ensure. The invention provides the safe and reliable construction method with lower cost.

Description

technical field [0001] The invention relates to a building construction method, in particular to a construction method of a large-span single-layer reticulated shell steel structure. Background technique [0002] With the progress of society and the development of economy and science and technology, people's pursuit of life and sensory requirements are getting higher and higher, and some more novel architectural forms have emerged as the times require. In recent years, a type of large-span single-layer reticulated shell steel structure with a shell-shaped surface appearance has gradually become a representative of many novel architectural shapes. [0003] Take the station roof structure of the Beijing-Tianjin intercity Yujiabao Station as an example. The roof is a shell-shaped single-layer reticulated steel structure with a maximum span of 143m and a height of 25.8m without any vertical support inside. For such a huge single-layer reticulated shell steel structure system, h...
