BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connection structure of beams, such as yoke beams, for use on the floor of a building.

In general, in a building such as a collective house, a floor partitioning the space above the floor and the space below the floor is constructed by horizontally fixing a plurality of yoke beams in parallel to a body such as a concrete body, and a joist on the floor. The upper plate is formed by sandwiching a base plate, etc., but when using the space under the floor as a space for storing an object, it is necessary to open the opening so that the floor can be opened and closed by a hatch. have. In such a case, in order to reinforce the free end of the yoke beam that is cut and cantilevered to form the opening, another yoke beam is arranged in the direction crossing the yoke beam. The yoke beam is integrally coupled to the yoke beam using a connector to reinforce the yoke beam around the opening.
