Embodiment Construction

[0022] The present invention will be further described below in conjunction with the accompanying drawings.

[0023] The present invention is a multi-chamber concrete-filled steel tube combined L-shaped column, which is directly welded into an L-shaped cross-section by a plurality of rectangular (square) thin-walled steel pipe profiles, and each square (rectangular) steel pipe forms an independent chamber, and then in each chamber Fill with concrete. The rectangular (square) steel pipe mentioned above is a steel pipe profile produced by a steel factory, and its size conforms to the national standard for rectangular (square) steel pipes. First, cut rectangular and / or square steel pipe profiles according to the design size, and then weld more than three rectangular and / or square steel pipe profiles into an L-shaped section according to the design size of the section. (GB50018-2002) design, using trumpet-shaped welds, arranged at the rounded corners of rectangular and / or square ...

Abstract

The invention discloses a multi-chamber type steel pipe and concrete combined L-shaped column. An L-shaped sectional steel pipe is formed by welding three or more rectangular and / or square steel pipes, and each rectangular and / or square steel pipe form a chamber; and concrete is poured into each chamber to form the multi-chamber type steel pipe and concrete combined L-shaped column. The steel pipes are steel pipe profiles produced by a steel factory, so that welded joints are few, is the machining is convenient, the cost is low, and the quality is easy to guarantee. The multi-chamber type steel pipe and concrete combined L-shaped column fully develops the characteristics of materials and sections, so that the mechanical property of the L-shaped column is improved. The multi-chamber type steel pipe and concrete combined L-shaped column is convenient to process and low in manufacturing cost and is suitable for wide popularization; and the economical benefit of the steel pipe and concrete combined L-shaped column is greatly improved.

Description

technical field [0001] The invention belongs to the field of construction engineering, and in particular relates to a multi-chamber steel pipe concrete composite L-shaped column. Background technique [0002] With the continuous development of society and economy, the requirements for green and environment-friendly buildings are constantly increasing. my country has a large population and needs a large number of residential buildings. For a long time, concrete structures have been the main structural form of residential buildings. With the continuous increase in steel production, it is the general trend for steel to be used in residential buildings. Compared with reinforced concrete columns, steel tube concrete columns have superior mechanical properties such as high bearing capacity and good ductility, and also have engineering advantages such as small footprint, light structure weight, no need for formwork and steel bar processing, and fast construction speed. Compared wi...
