PC PC SRC PC the SRC connection structure between precast concrete column and precast concrete beam the plate connection structure between precast concrete upper column and precast concrete lower column

摘要

According to an aspect of the present invention, there is provided a method of installing a PC beam on a vertically installed upper column, A column bracket 130 is installed at a lower end of the column concrete 110 of the upper column 100 and a column bracket 140 is installed at a side of the column steel frame 130 And a connection plate 150 is installed on the column bracket 140, A column main shaft 120 protrudes from the lower end of the column concrete 110 and is nut-coupled to the column lower plate 160, The PC beam 300 protruded from the upper end of the beam concrete 360 is bolted to the connecting plate 150 so that the beam 340 is bolted to the connecting plate 150, One end of the reinforcing bar 500 is inserted into the end of the PC beam 300, And the reinforcing bar 520 is joined to the other end of the reinforcing bar 500. The SRC coupling structure of the PC column and the PC beam is provided. 1. Inorder to realize an interior pillaras an embodiment, In order for the four PC beams 300 to be installed on four sides of the upper column 100, The column brackets 140 are respectively installed on four sides of the column steel frame 130, And the reinforcing bar (500) penetrates through the upper column (100). 2.As an example,To realize theexteriorcolumn, In order for the three PC beams 300 to be installed on three sides of the upper column 100, The column brackets 140 are respectively installed on three surfaces of the column steel frame 130, The reinforcing bars 500 of the two opposite PC beams 300 penetrate through the upper pillars 100, Anchor ribs 800 bent in a line are inserted into one surface of the upper column 100 where the PC beam 300 is not installed, One end of the anchor rib 800 and the other end reinforcement 500 of the PC beam 300 installed on the opposite side of one side of the upper column 100 where the PC beam 300 is not installed are connected to a coupler C) of the PC column and the PC beam. 3. Inorder to realize a corner postas an embodiment, In order to install the two PC beams 300 on two sides of the upper column 100 at right angles, The column brackets 140 are respectively installed on two surfaces of the column steel frame 130 on which the PC beam 300 is installed, Anchor ribs 800 bent in a line are inserted into two sides of the upper column 100 where the PC beam 300 is not installed, One end of the anchor rib 800 and the other end reinforcement 500 of the PC beam 300 installed opposite to two sides of the upper column 100 where the PC beam 300 is not installed are connected to a coupler C) of the PC column and the PC beam. 4. AndupperandlowerPC columnBy improving themutualcoupling structure, The upper pillars 100 are installed on the lower pillars 200, A column bracket 130 is installed at a lower end of the column concrete 110 of the upper column 100 and a column bracket 140 is installed at a side of the column steel frame 130 And, A column top plate 260 is installed at an upper end of the lower column 200, The upper and lower PC column-to-plate coupling structures are bolted to each other between the column lower plate (160) and the column top plate (260).
