Floor bearing capacity checking calculation and formwork removal construction method under concrete construction load effect

Abstract

The invention belongs to the field of integration of building structure design and construction technology, and particularly relates to a floor bearing capacity checking calculation and form removal construction method under the concrete construction load effect, which is characterized by comprising the following steps of: 1, determining a floor bearing capacity checking calculation object; 2, determining a floor formwork supporting system scheme; 3, calculating a frame beam line load; 4, carrying out secondary beam line load calculation; 5, calculating the load of the cast-in-place slab surface; 6, carrying out floor modeling and bearing capacity checking calculation; 7, determining the formwork dismantling time; 8, dismantaling the formwork. The invention relates to a bearing capacity checking calculation and form removal construction method when concrete construction load orthographic projection of an upper-layer floor system is transmitted to a lower-layer floor system. Compared with the prior art, during multi-layer structure construction, the formwork configuration amount is saved by 1 / 3, the floor system support formwork removal time is shortened by 1 / 3, under the conditionthat the structure safety is ensured, a large number of formworks are saved, the construction period is greatly shortened, a large number of comprehensive expenses are saved, and the efficient and energy-saving green construction requirement is met.

Description

technical field [0001] The invention relates to a construction method for checking and calculating the bearing capacity of a floor under the action of a concrete construction load and removing the formwork, which belongs to the field of integration of structural design and construction technology, and is suitable for floor bearings of structural forms such as concrete well-shaped beams and primary and secondary beams in large-area public buildings Force checking and formwork demolition construction. Background technique [0002] At present, there are more and more large-scale public buildings such as teaching buildings, gymnasiums, libraries, and large shopping malls. However, the traditional construction methods use a huge amount of formwork and steel pipe supports, and are often forced to stop work due to the shortage of steel pipe rental market, and due to formwork purchase and production costs, The comprehensive construction costs such as steel pipe rental fees are high,...

[0002] At present, there are more and more large-scale public buildings such as teaching buildings, gymnasiums, libraries, and large shopping malls. However, the traditional construction methods use a huge amount of formwork and steel pipe supports, and are often forced to stop work due to the shortage of steel pipe rental market, and due to formwork purchase and production costs, The comprehensive construction costs such as steel pipe rental fees are high, often resulting in meager profits or even losses for the project
