Abstract
In a joint structure of steel beam structure, a bracket is coupled and fixed to the lateral side of a large beam or a pillar and a steel beam is coupled to the bracket such that the steel beam is coupled to the lateral side of the large beam or the pillar. One end of the bracket is coupled to the lateral side of the large beam or the pillar, and the other end is inclined such that the lower part thereof forms an acute angle, wherein a first attachment plate is coupled to the inclined end part of the bracket such that a fixed length thereof protrudes from the upper end of the bracket. The lower part of one end of the steel beam is inclined at an obtuse angle so as to correspond to the other inclined end of the bracket.
Claims9
A joint structure of steel beam for fixedly connecting a bracket to the side surface of a column or girder and a steel beam to the bracket so that the steel beam is connected to the side surface of the column or girder, the joint structure of steel beam comprising:
- the bracket having one end coupled to the side surface of the column or girder and the other end whose lower portion formed slantly to an acute angle;
- a first connection plate coupled to the slant end portion of the bracket in such a manner as to protrude from the top of the bracket by a given length;
- the steel beam having one end whose lower portion formed slantly to an obtuse angle in such a manner as to correspond to the slant other end of the bracket;
- and
- a second connection plate coupled to the slant end portion of the steel beam in such a manner as to protrude from the top of the steel beam by a given length,
- wherein the first connection plate has a pair of guide parts protruding from the steel beam side lower portion thereof in such a manner as to be spaced apart from each other, and the second connection plate has chamfered portions formed on both sides of the lower end thereof in such a manner as to allow the lower end thereof to be inserted into the pair of guide parts;
- and
- each of the bracket and the steel beam has an upper flange, a lower flange and a web connecting the upper flange and the lower flange with each other, so that the bracket and the steel beam are connected to each other by fastening the first connection plate and the second connection plate to each other by means of tension bolts TB above and under the upper flanges of the bracket and the steel beam to transfer tension forces between the upper flanges.
