Its purpose is in order to increase the whole bending modulus of edge of a wing connecting plate 5 and the area of being connected of girder steel 2 and steel-pipe column 1, also is used for obtaining great bending section modulus promptly to and stronger welding seam is connected.
The size of rectangular plate 7 is less, and especially the part that edge of a wing connecting plate 5 is located girder steel 2 above has less size, has very big meaning to the floor construction, especially industrialization floor product construction, not only is favorable to guaranteeing the protective layer thickness of floor reinforcing bar, makes things convenient for the reinforcing bar to set up, has still reduced the influence of laying to the industrialization template of floor.
Of course, the flange connecting plate 5 can be provided with no reinforcing plate 8 and only comprises the rectangular plate 7, so that the structure is more compact.
In the concrete scheme, one end of the reinforcing plate 8, which is far away from the steel pipe column 1, is an inclined plane or a curved surface, the section of the reinforcing plate 8 is gradually reduced through the inclined plane or the curved surface, and the section is gradually changed to a smaller shape according to a bending moment attenuation curve so as to ensure the anti-seismic target of a strong node, a strong connection and a weak member.
In the concrete scheme, reinforcing plate 8 can set up two, is located the both sides of rectangular plate 7 respectively, and the rectangular plate 7 structure and the same, the symmetry setting of size of both sides, perhaps, reinforcing plate 8 only sets up one, is located one side of rectangular plate 7, makes things convenient for same type node to obtain the flange connecting plate 5 of four the same specifications, the industrialization preparation of being convenient for.
In the further scheme, with two edge of a wing connecting plates 5 of one side can be structure as an organic whole, applicable in the less girder steel 2 of size, perhaps for the components of a whole that can function independently structure that the interval set up, applicable in the great girder steel 2 of size, can be applicable to not unidimensional girder steel 2 respectively, use more in a flexible way.
In the specific scheme, the reinforcing plate 8 is in a right trapezoid shape, as shown in fig. 7, the side surfaces of the flange connecting plates 5 can be overlapped end to form an integral plate, that is, the flange connecting plates 5 can be processed by using strip-shaped steel plates similar to rectangles, and an optimal processing mode is adopted, so that materials can be saved and processing is convenient.
When the span of the I-shaped steel beam 2 is within a certain range, the flange connecting plate 5 can determine the fixed specification and size of the steel beam 2 with a certain specification, so that the strong connection of weak components is conveniently ensured;
because the national standard beam specification is fixed, and the beam specification in the 'guide for the size of main components of steel structure dwelling house' proposed by the ministry of construction is fixed, and the beam specification is relatively fixed, the flange connecting plate 5 can be manufactured into an industrialized product, and the standard specification connecting plate is manufactured by matching with the standard specification beam aiming at the directional manufacture of the standard specification beam, so that the building industrialization process is promoted.
In one embodiment, at least one reserved gap 9 is reserved between the end face of the flange plate 4 and the outer side face of the steel pipe column 1, the reserved gap 9 is arranged between the flange connecting plate 5 and the steel pipe column 1 and used for enabling a pipeline to penetrate from the upper side of the steel beam 2 to the lower side of the steel beam 2, for example, a switch control wire of a lamp needs to be arranged in a floor slab or a ceiling, the installation can be carried out through the reserved gap 9, the wiring is more reasonable and convenient, and the building is more compact and attractive;
in the further scheme, the reserved gap 9 is located at the end part of the flange plate 4, the beam web plate 3 penetrates through the middle part of the reserved gap 9 and separates the reserved gap 9 into two pipe penetrating channels, the reserved gap 9 can be used as an unstressed part, and the welding of the beam web plate 3 or the transition plate and the steel pipe column 1 is facilitated while the pipeline is conveniently penetrated and arranged.
In a further scheme, the reserved gap 9 is sealed by concrete or elastic sound insulation materials after a pipeline is penetrated, so that the sound insulation problem is solved.
When there is not the infilled wall below the beam column node, should set up articulated node, avoid influencing the building function.
