  • the second bracket 160 connected to the horizontal member is slidably fastened in the vertical direction, so that the first bracket 150 and the second bracket 160 made of iron or aluminum alloy are not provided without providing a separate cover member. Since the bottom surface and the tension material receiving sockets 170 and 180 are provided in a built-in structure that is not exposed to the outside, the aesthetics are beautiful and deformation from a fire can be prevented, thereby preventing secondary accidents such as collapse.
  • the structure of the double tension material-introduced column and beam according to the present invention is not limited to a built-in structure, and is constructed without forming a separate groove on the vertical member, so that separate cover members are attached to the exposed surfaces of the component parts. It can be provided in the form.
  • the structure of the double tension member-introduced column and beam according to the present invention is provided with an upper tension member and a lower tension member, so that the tension applied to the lower tension member can be increased, and as a result, the flexural strength of the structure can be improved. It has an advantage.
  • the vertical member and the horizontal member can be easily fastened by sliding in the vertical direction, and the tension member receiving sockets to which the prestressed tension member are coupled are fastened to the first bracket, so that the position is fixed and rotatable. It is possible to offset the transmitted rotational load and has the advantage of preventing secondary accidents such as collapse by providing a built-in structure in which components are not exposed to the outside.
  • the present invention can be applied not only to wooden buildings, but also to structures of pillars and beams of various buildings, and furthermore, it can be used as structures such as bridges.

Abstract

La présente invention concerne une structure de colonne-poutre et, plus particulièrement, une structure de colonne-poutre introduite par double tendon dans laquelle un élément vertical et un élément horizontal sont couplés coulissants et fixés par un connecteur, améliorant ainsi la facilité de fixation et de construction de l'élément vertical et de l'élément horizontal, et des tendons précontraints étant respectivement formés au niveau de la partie supérieure et de la partie inférieure de l'élément horizontal sous la forme de bois stratifié à la colle, améliorant ainsi la tension appliquée à l'élément horizontal, et permettant ainsi d'améliorer la résistance à la flexion.
