Spiral compound post

Abstract

The invention provides a spiral compound post, belonging to the technical file of civil building and bridge, mainly comprising building blocks, embedding reinforcing steel bars, overlapping reinforcing steel bars, and adhesive; wherein each of the building block is provided with one embedding reinforcing steel bar; four building blocks can form a base layer of the post according to four sides of the rectangle on the same horizontal plane; each base layer is overlapped vertically to form an integral post. Each embedding reinforcing steel bar and each building block form an integer through a connection action of the overlapping reinforcing steel bars. The juncture of each building block is coated with the adhesive. The spiral compound post preferably uses energy-saving and environment-friendly main materials, and has the advantages of rational stress, small steel usage, good ductility, industrial production, short construction period, low comprehensive cost, etc., can be widely applied to various building structures and bridges, and has obvious technical meanings and social benefits.

Description

a technical field [0001] The invention relates to a column structure in the construction field, in particular to a spiral composite column based on block materials and steel bars. Two background technology [0002] Columns (including piers) are one of the main components of industrial and civil buildings and bridges, and their safety, economy, and manufacturing convenience directly affect the performance indicators of the entire structure. Existing column types mainly include steel columns, reinforced concrete columns, steel tube concrete columns (for example, "square, rectangular or polygonal steel tube concrete columns reinforced with steel bars", patent No. 200610151197.4), composite steel concrete columns (for example, "combined steel and Concrete Column and Construction Method thereof”, Patent No. 98805134.6), composite material column (for example, “Concrete Column Wrapped in Glass Fiber Cloth PVC Tube”, Patent No. 200720060234.0; “High Density Polyethylene Tube Concre...

AI Technical Summary

Problems solved by technology

These column structures can meet the requirements in terms of strength and rigidity, but consume more steel or concrete, and the production of steel and cement requires a lot of natural resources and energy

Although the introduction of columns made of glass fiber, polyethylene and other materials can improve this problem, it is difficult to popularize due to problems such as cost.
