Problems solved by technology

[0003] In the current design and transformation of denitrification, the steel structure support structure in the denitrification area is mostly designed as a steel structure frame support structure. This force structure has greatly improved the horizontal lateral force resistance of high-rise steel structures compared with pure steel structure frames, but The steel used for the vertical support of the stressed structure is still not economical enough (steel structure investment is relative to process investment), and in the process of steel structure frame design, it is difficult for the designer to arrange the support, and the steel structure support is easy to affect the process function (such as Support arrangement affects maintenance access, etc.)

Embodiment 1

[0028] In a specific embodiment of the present invention, the denitration steel structure support includes a steel plate shear wall 1, a frame column 2 and a frame beam 4, and the steel plate shear wall 1 is arranged on the denitration steel formed by the frame column 2 and the frame beam 4 On both sides of the short axis of the structure, the shear wall 1 is located on the central line of the boiler. There are generally no requirements for process maintenance near the boiler centerline and on both sides of the blower maintenance support. Based on this, the invention arranges the steel plate shear walls on the boiler centerline and both sides of the short axis of the denitrification steel frame, such as figure 1 As shown, fully consider the requirements of process equipment layout and maintenance, and avoid process equipment and maintenance space. The steel plate shear wall 1 is connected to the steel plate shear wall side column 3, and the shear wall side column is specifical...

Embodiment 2

[0030] The present invention comprises a steel plate shear wall 1, a frame column 2 and a frame beam 4, and is characterized in that the steel plate shear wall 1 is arranged on both sides of the short axis of the denitration steel structure composed of the frame column 2 and the frame beam 4, The relative height of the denitration steel structure support is generally about 50 meters, and the plane frame support structure should be arranged every 7 meters or so. figure 1 , so that the slenderness ratio of the frame column 2 is within an appropriate range. Because the denitrification steel frame is sometimes limited by the process, some of the spans are relatively large, and the horizontal support 5 of the frame can be used to transmit the horizontal force and reduce the calculated length of the frame beam 4 and reduce the displacement between floors.

Embodiment 3

[0032]The length of the long axis side of the denitration steel structure support of the present invention is generally between 30 meters and 50 meters, and the width of the short axis side is generally about 15 meters. Generally, the stiffness of the long axis of the steel frame is much greater than the stiffness of the short axis. The horizontal lateral force on the short-axis structure of the denitration steel frame is also much greater than that on the long-axis. According to the above characteristics, the denitrification steel frame can be arranged with frame support on the short axis boiler center line and both sides of the steel frame-steel plate shear wall structure such as image 3 shown. Arrange the frame support structure in the long axis such as figure 2 , set on the boiler side and dust removal side such as figure 1 On both sides, vertical supports 7 transfer vertical loads and reduce the calculated length of frame beams and distribute horizontal lateral forces...

Abstract

The invention relates to a support with a denitration steel structure, comprising a denitration steel structure consisting of multiple frame columns (2) and multiple frame beams (4), wherein at least two steel plate shear walls (1) are arranged on the denitration steel structure, the steel plate shear walls are arranged on short shafts on two sides of the denitration steel structure and a central line between the short shafts towards a boiler. The support with the denitration steel structure provided by the invention is suitable for various industrial steel structure high-rise supports and various industrial steel structure high-rise factories. A shear wall is added in the denitration steel structure, so that integral steel dosage and foundation engineering quality of the support with the denitration steel structure can be effectively reduced; moreover, beam columns and a bearing surface can be effectively reduced, a whole framework is lightened, vertical supports are reduced, a process can be conveniently arranged, and a steel framework structure has a good antiknock characteristic. A stress structure is especially suitable for a tightly closed high-rise steel structure.

Description

technical field [0001] The invention relates to a steel frame structure, in particular to a denitrification steel frame structure. The structure proposed by the invention is applicable to various industrial steel structure high-rise supports and various industrial steel structure high-rise factory buildings. Background technique [0002] According to domestic environmental protection requirements, during the "Twelfth Five-Year Plan" period, NO X The peak of key governance. In the current denitrification design, the selective catalytic reduction (SCR) method is a relatively common denitrification technology in the industry. In this technology, denitrification is generally divided into ammonia area (or urea area) and SCR denitrification reaction area. Because most of the denitrification of power plants is a renovation project (the power plant has been built for many years, and no denitrification facilities have been installed before), the denitrification area is generally ar...
