Embodiment Construction

[0044] Below in conjunction with accompanying drawing, the concrete steel formwork support construction method of the present invention is described in detail below.

[0045] As shown in the accompanying drawings, the concrete steel formwork support construction method of the present invention, the steps of the construction method include:

[0046] A. Load calculation

[0047] 1. The relevant parameters are selected according to the specific gravity of concrete 24 KN / m3, the specific gravity of steel bar 1.5KN / m3, the template 0.15KN / m2, the support 0.1KN / m2, and the vibration load 2 KN / m3

[0048] 2. Concrete load N1=57.6 KN, steel load N2=3.6 KN, support load N3=4.8KN, vibration load N4=4.8KN

[0049] 3. Single-layer combined load, the load factor is 1.2, N=(57.6 KN+3.6 KN+4.8 KN+4.8)×1.2KN =84.96KN

[0050] 4. The load acting on the simply supported steel beam is calculated according to the uniform load, and the uniform load q is calculated (four steel beams are preset to...

Abstract

The invention provides a concrete steel formwork support construction method. The construction method comprises the following steps: load calculation, support system selection, steel beam type selection, anchor bar calculation, construction, H-shaped steel mounting, formwork arch camber and steel beam platform removal. The concrete steel formwork support construction method successfully solves the problems in the bottom frame erection, fixation, construction and the like of an ultrahigh suspended concrete beam. The method is suitable for the construction of an ultrahigh large-span courtyard reinforced concrete beam slab structure. The method has the advantages of convenience in construction and operation, simple construction technology, easiness in mastering, high production efficiency and relatively good applicability. Compared with tradition frame scheme, the method has high safety factor and does not cause potential safety hazard.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a construction method for supporting a concrete steel formwork. Background technique [0002] In general, the atrium in a building has significant functions such as introducing natural light, creating a comfortable environment and good ventilation, which has a certain impact on people's vision. Therefore, buildings with an atrium structure are favored by designers. Atrium structures often have the characteristics of large span, large height, and large space, which often bring great challenges to construction companies during construction. Contents of the invention [0003] The technical task of the present invention is to solve the deficiencies of the prior art, and provide a construction method for concrete steel formwork support. [0004] The technical scheme of the present invention is realized in the following manner, the concrete steel formwork supports t...
