Embodiment 1

[0040] Embodiment one: by Figure 1 to Figure 8 Given, the conversion connection structure of the prefabricated reinforced concrete structural column with variable cross-section joint steel bars, including the upper section column 1 and the lower section column 3, the lower section column 3 is connected to the frame beam 9, the upper section column 1 and the lower section column A conversion steel plate 5 is arranged between the columns 3, and the first connection hole 6, the second connection hole 7 and the reserved hole 13 for pouring are reserved on the surface of the conversion steel plate 5. material, vibrating and exhaust to provide the cut-in, the grouting sleeve 11 corresponding to the second connection hole 7 is set in the upper section column 1, the grouting sleeve is assembled before the concrete pouring of the section column, the grouting sleeve 11 and the Short ribs 8 are arranged between the second connection holes 7, and the connection between the upper section ...

Embodiment 2

[0041] Embodiment 2: On the basis of Embodiment 1, there are multiple first connecting holes 6 and they are evenly distributed on the four corners of the conversion steel plate 5 corresponding to the lower section column 3, and there are multiple second connecting holes 7 And evenly distributed on the conversion steel plate 5 at the position corresponding to the four corners of the upper section column 1, the upper section column 1 is placed in the center of the lower section column 3 to keep concentric with the lower section column 3, and the frame beam 9 is in a ten-fold shape around the lower section column. This type of joint column connection is used for the middle joint column in the concrete frame system with variable cross-section columns. The two sides of the upper joint column 1 are respectively kept corresponding to the two sides of the lower joint column 3, and the frame beam 9 is in the lower joint. The two sides of the section column 3 that are not corresponding t...

Embodiment 3

[0042] Embodiment 3: On the basis of Embodiment 2, the first connecting hole 6 is a conical hole with a wide top and a narrow bottom, which facilitates the insertion of the second longitudinal steel bar 4 and converts the diameter of the first conical connecting hole 6 on the steel plate. According to the second longitudinal steel bar of the lower section column, the diameter is appropriately enlarged and reserved; the second connection hole 7 is a rounded table hole with a narrow top and a wide bottom, and is inserted with the short rib 8 to convert the second connection of the rounded table shape on the steel plate The aperture of the hole 7 is properly enlarged and reserved according to the diameter of the short rib, and the short rib 8 and the second connecting hole 7 are welded and fixed by means of perforated plug welding, and the second longitudinal steel bar 4 and the first connecting hole 6 are fixed by perforating Welding and fixing by plug welding.

Abstract

The invention relates to the technical field of building engineering and fabricated concrete structures, and in particular to a conversion connection structure of a fabricated structural column variable cross-section node steel bar and an implementation method. A traditional joint steel bar conversion connection structure needs to bend the steel bar. The conversion connection structure of the fabricated reinforced concrete structural column variable cross-section node steel bar comprises an upper section column and a lower section column, wherein a conversion steel plate is arranged between the upper section column and the lower section column, a first connecting hole, a second connecting hole and a pouring reserved hole are reserved on the surface of the conversion steel plate, a groutingsleeve is arranged in the upper section column, a short bar is arranged between the grouting sleeve and the second connecting hole for connection, a second longitudinal steel bar in the lower sectioncolumn is connected with the first connecting hole, concrete layers are among between the short bar, the conversion steel plate and the second longitudinal steel bar to form a whole, the steel bar does not need to be bent, a reasonable linear stress state of the steel bar is guaranteed, and a good development prospect is achieved in the technical field of building engineering combined structures.

Description

technical field [0001] The invention relates to the fields of construction engineering and assembled concrete structures, in particular to a conversion connection structure and an implementation method of steel bars at nodes with variable cross-sections of assembled structural columns. Background technique [0002] The construction industry is the pillar industry of the national economy. In recent years, my country has vigorously advocated the assembly of concrete buildings. Concrete structure has extremely important significance and function. [0003] In multi-story and high-rise reinforced concrete structures, with the change of vertical and horizontal loads, the vertical members will have the phenomenon of concrete variable section and vertical reinforcement diameter and root number. At present, in the prefabricated reinforced concrete structure , it is a technical problem to deal with and convert the joints of the steel bars at the variable cross-sections of the vertical...
