Embodiment Construction

[0044] The construction method of the concrete steel formwork support of the present invention will be described in detail below with reference to the accompanying drawings.

[0045] As shown in the 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 value of the relevant parameters is 24 KN / m3 for concrete, 1.5KN / m3 for steel bar, 0.15KN / m2 for formwork, 0.1KN / m2 for support, and 2 KN / m3 for vibration load.

[0048] 2. Concrete load N1=57.6 KN, steel bar 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 in accordance with the uniform load, and the uniform load q is calculated (four steel beams are preset to form a force support platform)

[0051] q=84.96KN÷12m=7.0...

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 of concrete steel formwork support. Background technique [0002] Generally, the atrium in a building has significant functions such as the ability to introduce natural light, create a comfortable environment and good ventilation, and cause a certain impact on people's vision. Therefore, buildings with atrium structures are favored by designers. Atrium structures often have the characteristics of large span, large height, large space, etc., which often bring greater challenges to construction companies during construction. Summary of the invention [0003] The technical task of the present invention is to solve the shortcomings of the prior art and provide a construction method for supporting concrete steel formwork. [0004] The technical scheme of the present invention is realized in the following way. The concrete steel formwork supports the con...
