Column and beam construction

Abstract

The objective is to obtain a reusable column-beam joint structure that allows for the joining of multiple beams of different heights. [Solution] The column-beam joint structure comprises a first precast joint member 30X having a lower precast column member 20L, a first concrete joint portion 40X detachably joined to the upper surface of the lower precast column member 20L, and a first steel beam bracket 50X embedded in the first concrete joint portion 40X with its end protruding from the first concrete joint portion 40X; and a second precast joint member 30Y having a second concrete joint portion 40Y detachably joined to the upper surface of the first concrete joint portion 40X, and a second steel beam bracket 50Y embedded in the second concrete joint portion 40Y with its end protruding from the second concrete joint portion 40Y in a direction different from that of the first steel beam bracket 50X.

Claims

1. Concrete pillars and A first precast joint member having a first concrete joint portion detachably joined to the upper surface of the concrete column, and a first steel beam bracket embedded in the first concrete joint portion with its end protruding from the first concrete joint portion, A second precast joint member having a second concrete joint portion detachably joined to the upper surface of the first concrete joint portion, and a second steel beam bracket embedded in the second concrete joint portion, the end of which protrudes from the second concrete joint portion in a direction different from that of the first steel beam bracket, A column-beam joint structure equipped with this feature.

2. The second precast joint member has a plurality of second steel beam brackets, each of which protrudes from the second concrete joint portion in a direction different from that of the first steel beam bracket. The column-beam joint structure according to claim 1.

3. A PC steel member extends from the upper surface of the concrete column and passes through the first concrete joint and the second concrete joint so as to be slidable in the vertical direction, A fixing device for fixing the tensioned PC steel material to the upper surface of the second concrete joint and for press-fitting the lower surface of the second concrete joint and the upper surface of the first concrete joint via a joint material, A column-beam joint structure according to claim 1 or claim 2, comprising the above.
