Fastener type steel pipe scaffold framework support applicable to steel reinforced concrete beam

Abstract

The invention relates to a fastener type steel pipe scaffold framework support applicable to a steel reinforced concrete beam. The support is built by steel pipes with the specification Phi being 48*3.5, all nodes are connected with one another by fasteners, the support has 34 spans in the longitudinal direction and 4 spans in the transverse direction and is 10.3m high, the step of vertical rods is 1.2m, the longitudinal spacing of the vertical rods is 0.6m, the transverse spacing of the vertical rods is 0.6m, an adjustable support base is arranged at the upper part of the support, a dual-aluminum beam with the specification being 70mm*150mm serving as a main beam for supporting a framework is arranged on the adjustable support base, the bottom of the adjusting support base is inserted in the support to be fixed, and the adjustable support base extends out of the steel pipes of the vertical rods by 0.2m and is adjustable in the range of 0.2m. The upper part of the support is provided with a steel reinforced concrete beam framework, the dead load of concrete is loaded on the framework in a construction process, and the load, transferring to the vertical rods, of the framework, is half of the total dead load of the concrete. The fastener type steel pipe scaffold framework support is safe and stable in structure and is applicable to a large-section large-span and large-volume steel reinforced concrete beam framework support system.

Description

technical field [0001] The invention belongs to the field of civil engineering, and in particular relates to a formwork support for building site construction, in particular to a fastener-type steel pipe scaffold formwork support suitable for large-section, large-span, and large-volume steel-concrete beams. Background technique [0002] In recent years, with the development of the national economy, steel concrete structures have been widely used. Steel concrete engineering construction with large span, high support and heavy load often occurs. Due to the large self-weight and construction load of the long-span steel concrete structure, a reasonable formwork support scheme must be selected according to the actual situation of the project to ensure that the support system has sufficient strength, stability and reasonable engineering volume. During the construction process, the area enclosed by the formwork panels determines the shape of the steel concrete structure, and the f...

AI Technical Summary

Problems solved by technology

For steel concrete beam projects with long spans, high supports, and heavy loads, the design method of the lower support system usually refers to the design method of the formwork support of reinforced concrete beams, and some do not consider the ability of steel concrete beams to bear part of the concrete. The design of the formwork support is conservative, resulting in a waste of manpower and material resources during construction; some consider too much the role of steel beams, causing safety hazards, and some even cause major safety accidents
