Embodiment 1

[0024] see Figure 1-2 , the variable cross-section frame beam is composed of a mid-span structural beam and a bearing segment structural beam.

[0025] According to the existing technical conditions of a building, the structural beam height is 0.8 meters, the beam width is 0.3 meters, and the pipeline height at the intersection is 0.2 meters. According to the existing technical solution, the building floor height = 2.2 (clear height requirement) + 0.8 (beam height) + 0.2 (pipeline height) + 0.2 (installation height) = 3.4 meters.

[0026] use figure 1 The variable section frame beam shown: the height of the structural beam in the mid-span section is 0.5 m and the width of 0.3 m, and the height of the structural beam in the support section is 0.9 m and the width is 0.5 m. The required building floor height at the intersection = 2.2 (clear height requirement) + 0.5 (beam height) + 0.2 (pipeline height) + 0.2 (installation height) = 3.1 meters, and the required building floor ...

Abstract

The invention provides a variable cross-section frame beam. The variable cross-section frame beam is composed of a mid-span section structural beam and a support section structural beam, and during use, the two ends of the variable cross-section frame beam are connected with frame columns, and an electromechanical pipeline is installed at the bottom of the mid-span section structural beam. The device has the beneficial effects that the space height occupied by pipeline installation can be effectively reduced at the pipeline intersection, and the beneficial purpose of reducing the building floor height is achieved.

Description

technical field [0001] The invention belongs to the technical field of construction, and in particular relates to a variable-section frame beam. Background technique [0002] With the development of the economy, the functions of buildings are becoming more and more perfect, and the mechanical and electrical systems are becoming more and more complex. The mechanical and electrical installation involves the coordination and cooperation of various professions. Cross-problems, resulting in a large building height, waste of resources and energy, is not conducive to energy conservation and environmental protection. The height of the building generally needs to meet the requirements of the height of the building, the installation height of the mechanical and electrical pipelines, and the height of the structure. Therefore, the purpose of reducing the floor height, energy saving and carbon reduction can be achieved by controlling the beam height. Under the existing technical condit...
