Embodiment

[0033] refer to figure 1 , this embodiment provides a BIM technology-based design and optimization method for the single-side formwork support system of the side wall, and the specific steps are as follows:

[0034] 1) Basic data assumptions

[0035] According to the previous construction experience, the relevant material structure size of the side wall unilateral formwork support system is assumed, mainly including the size and spacing of the sub-keel square timber, the unilateral steel truss bracket size assumption, and the pre-embedded steel bar pull ring size assumption. Among them, the sub-keel square timber is assumed to be 100×100mm, the spacing is 40cm, and it is arranged horizontally; the single-side steel truss support is assumed to be welded by 12# channel steel and 10# angle steel, and the single-side steel truss spacing is 1.0m. The steel bars are processed, assuming that 32 round steel is used, and the layout spacing is assumed to be 50cm.

[0036] 2) Parametri...

Abstract

The invention provides a side wall single-side formwork supporting system design and optimization method based on the BIM technology. The method is characterized in that a side wall single-side formwork is established based on three-dimensional modeling software, and the establishment of the side wall single-side formwork mainly comprises the steps of establishing a long fiber reinforced thermoplastic composite form panel, establishing a back arris square timber and establishing a single-side steel truss support; the established three-dimensional model is assembled, and the assembled three-dimensional model is exported into an stl format; and the exported file is imported into stress analysis software, material characteristics are input, connection and boundary conditions are created, stress analysis is carried out, scheme optimization and structure size optimization are carried out according to a calculation result, and finally, the final design scheme is exported to be a constructiondrawing to guide field construction. According to the method, the problems that an existing side wall single-side formwork supporting system is low in design efficiency, complex in design, low in precision and tedious in modification, adjustment and optimization are solved. The invention belongs to the field of constructional engineering.

Description

technical field [0001] The invention relates to a BIM technology-based design and optimization method for a single-side formwork support system of a side wall, which belongs to the field of construction engineering. Background technique [0002] With the rapid development of national infrastructure construction, the construction safety of the project construction is particularly important, especially in the construction process of the side wall of the urban rail transit underground station, how to ensure the safety and reasonableness of the side wall unilateral formwork support system is very important. In particular, the construction method of combining the single side steel truss support of the conventional side wall with the square wood and long fiber reinforced thermoplastic composite formwork is extremely rare. The efficiency is low, the calculation is complex, error-prone, and the calculation accuracy is not high. Contents of the invention [0003] The present inven...
