Embodiment Construction
[0032] The technical solutions of the present invention will be further illustrated and described below through specific embodiments.
[0033] Such as figure 1 and figure 2 As shown, a prefabricated assembled steel concrete column splicing joint structure includes an upper steel concrete column 1 and a lower steel concrete column 2 with square cross sections, the lower end of the upper steel concrete column 1 and the upper end of the lower steel concrete column 2 The area in between is connection area 3.
[0034] The upper steel concrete column 1 includes an upper cross-shaped steel 10 in the middle and reinforced concrete surrounding the upper cross-shaped steel 10. The lower end of the upper cross-shaped steel 10 protrudes from the lower end of the upper steel concrete column 1, and the upper cross-shaped The lower end of the concrete column 1 has several upper outwardly extending longitudinal bars 11 arranged on the outer periphery of the lower end of the upper cross-sha...

Abstract
The invention discloses a prefabricated steel-reinforced concrete column splicing joint structure and a construction method thereof. The prefabricated steel-reinforced concrete column splicing joint structure comprises an upper steel-reinforced concrete column and a lower steel-reinforced concrete column, and an area between the lower end of the upper steel-reinforced concrete column and the upperend of the lower steel-reinforced concrete column is a connecting area. Ultra-high performance concrete is poured in the connecting area to enable the upper steel-reinforced concrete column and the lower steel-reinforced concrete column to be connected as a whole. The prefabricated steel-reinforced concrete column splicing joint structure applies the ultra-high performance concrete between the prefabricated steel-concrete columns, and fully utilizes the excellent compression resistance and tensile performance of the ultra-high performance concrete, thereby solving the problem of weak connection in joint regions.
Description
technical field [0001] The invention belongs to the technical field of building structures, and in particular relates to a prefabricated assembled steel concrete column splicing node structure and a construction method thereof. Background technique [0002] The prefabricated steel concrete structure is one of the important directions for the development of building structures in my country. The prefabricated steel concrete column has the advantages of controllable product quality, green environmental protection and convenient construction. The column-column connection method is an important connection method in the prefabricated structural system. It directly affects the construction speed and the degree of assembly of the structure. Therefore, the construction method of the column-column splicing joint should be as simple as possible, and its strength should not be lower than that of prefabricated steel concrete. column strength. However, the existing prefabricated steel c...
