Embodiment Construction

[0023] Next, the hybrid structure of the present invention and its construction method will be described with reference to the drawings.

[0024] Such as Figure 1 ~ Figure 3 As shown, concrete columns 10 are connected to column-to-beam connections 14 of steel beams 12 to form a hybrid structure 16 .

[0025] The concrete column 10 is erected on the ground 18, for example.

[0026] A plurality of PC steel rods 22 , which are PC steel, extend upward from the lower portion of the concrete column 10 , and protrude upward from a plurality of positions spaced apart along the circumferential direction of the outer peripheral portion of the upper end portion 10A of the concrete column 10 .

[0027] In this embodiment, the concrete column 10 has a rectangular cross section, and three PC steel rods 22 protrude upward from each of the four corners of the upper end 10A of the concrete column 10 . In addition, the number of the PC steel rods 22 can be appropriately determined according ...

Abstract

The purpose of the present invention is to make the cross section of a post smaller and improve the seismic performance of a building. PC steel wires (22) project upward from the four corners of an upper edge (10A) of a concrete post (10). A beam-to-post joint (14) has a steel beam section (12A), top and bottom band plates (30) attached to the top and bottom of the steel beam section (12A), an enclosing plate (32) that delimits the interior space and that is attached in between and around the top and bottom band plates (30), concrete (34) that is poured into the interior space, and a plurality of insertion holes (36A, 36B). For the beam-to-post joint (14), the bottom band plate (30) is mounted to the upper edge (10A) of the concrete post (10), and the PC steel wires (22) pass through the insertion holes (36A, 36B) and project upward from the top band plate (30). A tensile force is applied to the PC steel wires (22) on the top band plate (30), and the concrete post (10) and the beam-to-post joint (14) are pre-stressed.

Description

technical field [0001] The invention relates to a hybrid structure connected by prestressed concrete columns and steel beams and a construction method thereof. Background technique [0002] In the prior art, in buildings with hybrid structures, the columns are constructed of concrete and the beams are constructed of steel. [0003] [Patent Document 1] Japanese Invention Patent Laid-Open Publication No. 5-331912 [0004] Therefore, in the conventional hybrid structure in which the column is made of reinforced concrete, the cross-sectional area of ​​the column has to be increased in order to bear the weight of the building and the load during an earthquake. [0005] As a result, the weight of the building increases, which is not conducive to improving the seismic performance of the building. Contents of the invention [0006] In view of the above circumstances, the present invention has been proposed. The object of the present invention is to provide a hybrid structure con...
