Description

Arrangement method of bent upright posts Technical Field The invention belongs to the technical field of building construction formwork support systems, and particularly relates to a bent upright rod arrangement method. Background In the construction engineering, the erection of bent is an important link for guaranteeing construction safety and quality. Although the conventional bent upright arrangement is generally based on a construction scheme, in actual construction, the conventional bent upright arrangement still depends on wood turning (carpenter turning) and team experience to perform on-site adjustment to a great extent, and the following main defects exist in the method: First, the degree of standardization is low. The flexibility of field arrangement is adapted to actual changes, but specific adjustment is different from person to person and from team experience to team experience, so that unified construction standards are difficult to form, and difficulties are brought to standardization management and accurate estimation of material consumption. Second, material waste is easily caused. The arrangement of the steel pipe is dependent on experience judgment, unreasonable dense arrangement is easy to generate, the usage amount of materials such as the vertical rods, the steel pipes, the fasteners and the like exceeds the actual demand, and the engineering cost is increased. The existing bent calculation software is lack of pertinence in the arrangement of the vertical rods, for example, when beam members are processed, the software cannot be subjected to fine design according to the cross-section size of the beams, and a beam-slab unified arrangement mode is generally adopted. This "one-shot" approach is difficult to balance between safety and economy, and insufficient support may raise safety concerns, while excessive support directly results in wasted material and increased cost.
