Description
Technical field
The utility model relates to construction engineering technical field, especially relates to a kind of shaped steel and does not wait jowar beam jointing structure.
Background technology
Existing structural steel design; for reaching the design principles of economical rationality, safe and applicable, usually can carry out the uniform section form according to force request, different internal force adopts different cross sections; but, due to the needs that connect, the local deck-molding that usually can connect beam end is made the same.Like this, the height of beam end is exactly, according to the needs that connect structure, deck-molding has been set, and has caused unreasonablely economically, does not take full advantage of the strength and stiffness of beam.And, after depth of beam strengthens, because depth of beam strengthens, rigidity also increases thereupon, assigned moment of flexure will be increasing, causes connecting bolt too much, connects the blocked up situation of end plate, also increases larger difficulty in the construction simultaneously.If beam is made not contour direct connection, can cause moment of flexure effectively to transmit, cause beam stress inhomogeneous, even beam the phenomenons such as distortion occur after stressed.
The utility model content
The purpose of this utility model is exactly, in order to address the above problem, to provide a kind of simple in structure, easy for installation, and rigidity can continuous transition, moment of flexure can effectively be transmitted and economical rationality shaped steel do not wait jowar beam jointing structure.
To achieve these goals, the utility model adopts following technical scheme:
Shaped steel do not wait jowar beam jointing structure, it is located at the non-connecting portion that waits jowar, non-ly waits jowar to comprise:
Be located at the first beam of connecting portion one side;
Be located at the second beam of connecting portion opposite side, its deck-molding is greater than the deck-molding of the first beam;
The connecting portion of described first, second beam is provided with the connection end plate;
It is characterized in that, described the first beam bottom be provided with T shape transition piece, the horizontal component of this T shape transition piece is perpendicular to the connection end plate of the first beam end, and the vertical part of T shape transition piece is perpendicular to the bottom of the first beam.
Wherein, the height at the top of horizontal component to the first beam of described T shape transition piece is identical with the second depth of beam.
Wherein, described first, second beam shaped steel corrugated web girder steel for it.
Wherein, described T shape transition piece adopts flat web product.
Wherein, described T shape transition piece is T shape rebound, the frange plate that described horizontal component is T shape rebound, and described vertical portion is divided into the web part of T shape rebound.
Wherein, described web part is over against the first flange of beam center.
Wherein, described frange plate flushes with the flange of beam of the second beam bottom.
Wherein, the end, web part has the inclined plane of 45 degree.
Compared with prior art, the utlity model has following beneficial effect: with traditional flat web girder steel end plate, be connected and compare, connected mode of the present utility model has broken through traditional identical restriction of beam end height, different deck-moldings is connected and become possibility, the transition of T-shaped plate simultaneously, the rigidity that has also guaranteed beam is unlikely to produce sudden change, has guaranteed preferably the smooth transition of beam rigidity, thereby guarantees smooth transmission and the distribution of beam moment of flexure.
The accompanying drawing explanation
