Embodiment Construction
[0025] A single-sided steel plate concrete hollow composite roof proposed by the present invention is described in detail as follows in conjunction with the accompanying drawings and embodiments:
[0026] A single-sided steel plate concrete hollow composite roof proposed by the present invention is supported on the top of the side wall of the factory building, and its overall layout is as follows figure 1 As shown, the one-sided steel plate concrete hollow composite roof is spliced sequentially by several I-shaped steel reinforced concrete composite beams 1 with the same structure and arranged in parallel to form a flat cuboid box structure with multiple hollows in the middle. The axial direction of the bone concrete composite beam 1 is perpendicular to the long side wall 0-1 of the factory building, and the I-shaped steel reinforced concrete composite beam 1 is designed according to the requirement of one-way independent force, which provides guarantee for the temporary open...

The invention provides a unilateral steel plate and concrete hollow combined roof and belongs to the field of a large-span and large-space roof and floor system for nuclear power plants. The outer edges of the roof are connected with side building walls for supporting the roof. As for the roof, a plurality of I-shaped steel-reinforced concrete combined beams are sequentially spliced into a flat cuboid box-type structure with multiple hollow portions in the middle, all the I-shaped steel-reinforced concrete combined beams meet the requirement for one-way independent stress, and each I-shaped steel-reinforced concrete combined beam is of a combined structure that I-shaped steel-reinforced concrete half wraps an asymmetric I-shaped steel framework. By adoption of the formwork-free design, the purpose of cross-operation of construction and installation is achieved, meanwhile, the construction progress is accelerated, and the requirement of a project for the construction period is met. The unilateral steel plate and concrete hollow combined roof further has the characteristic that openings for suspension of large-scale equipment are formed temporarily without influencing integral stress of the roof, and meets the function requirements of roofs of nuclear power plants.
Description
technical field [0001] The invention belongs to the field of large-span and large-space roofs and floor systems of nuclear power plants, and in particular relates to the structural design of a single-side steel plate concrete hollow composite roof. Background technique [0002] High-temperature gas-cooled reactor (HTR-PM for short) is an advanced nuclear power reactor with independent intellectual property rights in my country and safety features of the fourth-generation nuclear energy system. It has inherent safety features, a wide range of applications, and broad prospects for commercialization. The high-temperature gas-cooled reactor nuclear power plant demonstration project is one of the major national projects, which is of great significance to promoting my country's entry into the forefront of fourth-generation nuclear power technology, promoting nuclear power manufacturing enterprises to increase scientific research efforts, and attracting cohesive nuclear power talent...
