Garage roof bearing capacity calculation and construction method under engineering vehicle load effect

Abstract

The invention belongs to the building design and construction technology crossing field, and particularly relates to a garage roof bearing capacity calculation and construction method under the engineering vehicle load effect. The method is characterized by adopting the following steps of (1) confirming an underground garage roof bearing capacity checking calculation object; (2) checking and calculating the bearing capacity of a cast-in-place slab; (3) punching-resistance checking and calculating the cast-in-place slab; (4) checking and calculating the bearing capacity of a framed beam and a secondary beam; (5) selecting an engineering vehicle; (6) confirming a driving path of the engineering vehicle. According to the garage roof bearing capacity calculation and construction method under the engineering vehicle load effect provided by the invention, the bearing capacity checking calculation is carried out on the underground garage roof according to the most unfavourable condition of the engineering vehicle wheel-pressure function without considering the working condition of the accidental load and earthquake action. Under the condition of ensuring the structure safety, a building material transportation vehicle directly arrives at the destination from the garage roof, so that the secondary transportation of main building construction materials is avoided, the construction period is greatly shortened, the construction comprehensive cost is greatly saved, and the green construction requirements of high efficiency and energy conservation are met.

Description

technical field [0001] The invention relates to a calculation and construction method for the bearing capacity of a garage roof under the load of an engineering vehicle, and belongs to the cross field of architectural design and construction technology. It is applicable to the calculation and construction of engineering vehicles driving on all garage roof structural systems such as well-shaped beams, primary and secondary beams, membrane shells, and laminated dark boxes. Background technique [0002] The form of underground garages set up through the field area in the building complex has been widely used throughout the country. However, the fire exit area where 300KN engineering vehicles can drive on the roof of the underground garage is usually designed with a temperature post-casting zone, which makes it impossible to drive engineering vehicles in this area, and there is still a lack of scientific calculations for engineering vehicles driving on the roof of the undergroun...

AI Technical Summary

Problems solved by technology

Due to the super long horizontal pipeline for concrete conveying, the pumping phenomenon often occurs, which greatly reduces the efficiency of concrete pouring; because building materials and garage roof covering soil need to be transported twice to reach the destination, the comprehensive cost of construction and the construction period increase significantly. , has greatly affected the construction progress and economic and social benefits, and has become a national universal technical problem that needs to be solved urgently
