Abstract
The utility model relates to a save material's real abdomen girder steel and bracket roof beam connected node, including the bracket roof beam and by two girder steels of bracket roof beam connection, the node still includes two vertical steel sheets, and the longitudinal section of bracket roof beam is the I shape, including the riser with locate the riser both sides, be used for the supporting part that supports two vertical steel sheets respectively, the both sides of bracket roof beam are connected with two girder steels through two vertical steel sheets respectively. Compared with the prior art, the utility model discloses the bracket roof beam is almost on same horizontal plane with the overlap joint girder steel, and it is direct to pass power to only need bracket roof beam and vertical steel sheet to realize connecting promptly, save the material.
Description
Technical Field
The utility model relates to a bracket roof beam connected node especially relates to a save material's real abdomen girder steel and bracket roof beam connected node.
Background
The steel structure building of the portal rigid frame light house is more and more in form, the situation that a column needs to be drawn due to process and building requirements often occurs, and then a solid-web bracket beam is locally designed to connect the original solid-web rigid frame beam with the bracket beam.
In engineering, the common practice is to design the bracket beam below the rigid frame beam and connect the lower flange of the rigid frame beam with the upper flange of the bracket beam by using a high-strength bolt.
The advantage of doing so is to pass the power directness, but needs to add at bracket roof beam bottom flange and establish angle steel support, is connected with the bottom flange of rigid frame roof beam, guarantees bracket roof beam out-of-plane stability. In actual engineering, the construction of the node is not very convenient, the clear height of the building is greatly weakened, and the out-of-plane stability of the bracket beam is weak before the angle iron support is installed.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a material-saving solid web steel beam and bracket beam connected node in order to overcome the defects of the prior art.
The purpose of the utility model can be realized through the following technical scheme:
the utility model provides a material-saving's real abdomen girder steel and bracket roof beam connected node, includes the bracket roof beam and by two girder steels of bracket roof beam connection, the node still includes two vertical steel sheets, the longitudinal section of bracket roof beam is the I shape, includes the riser and locates the riser both sides, is used for supporting the supporting part of two vertical steel sheets respectively, the both sides of bracket roof beam are connected with two girder steels through two vertical steel sheets respectively.
The vertical plates are pre-provided with jointed plate connecting holes.
The central line of the vertical plate and the central line of the steel beam are at the same horizontal height.
And a stiffening plate is arranged on the vertical steel plate.
The stiffening plates are distributed around the steel beam.
The arrangement of the jointed board connecting holes preset on the vertical plate is I-shaped.
Compared with the prior art, the utility model discloses following beneficial effect has:
1) the bracket beam and the lap-joint steel beam are almost on the same horizontal plane, force transmission is direct, connection is achieved only through the bracket beam and the vertical steel plate, and materials are saved.
2) The linking mode is highly consistent with the stress of the model.
3) Out-of-plane angle supports are omitted.
4) The clearance in the building is not influenced by the height of the bracket beam, and no space height loss exists.

Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. The embodiment is implemented on the premise of the technical solution of the present invention, and a detailed implementation manner and a specific operation process are given, but the scope of the present invention is not limited to the following embodiments.
The utility model provides a solid web girder steel and bracket roof beam connected node of material saving, when the bracket roof beam design, just consider the vertical makeup height of rigid frame roof beam and installation reservation construction space, adopts vertical makeup with rigid frame roof beam and bracket roof beam web to be connected. The design is that the connection force transmission of the lap joint steel beam and the bracket beam is more direct, the construction is more convenient, the on-site secondary hoisting is avoided as much as possible, and the possibility of the out-of-plane instability of the bracket beam is reduced.
Specifically, as shown in fig. 1 to 3, the bracket comprises a bracket beam 1 and two steel beams 2 connected by the bracket beam 1, the joint further comprises two vertical steel plates, the longitudinal section of the bracket beam 1 is i-shaped, the bracket beam comprises a vertical plate 11 and supporting parts 12 arranged on two sides of the vertical plate 11 and used for supporting the two vertical steel plates respectively, and two sides of the bracket beam 1 are connected with the two steel beams 2 through the two vertical steel plates respectively.
The vertical plate 11 is provided with the jointed plate connecting holes 13 in advance, the jointed plate connecting holes 13 in advance in the vertical plate 11 are arranged in an I shape, so that the strength of the upper end and the lower end can be improved, the bending resistance is enhanced, as shown in fig. 1, the jointed plate connecting holes are divided into 9 rows arranged from top to bottom, and the number of the upper three rows and the lower three rows is larger than that of the middle three rows.
The central line of riser 11 is at same level with the central line of girder steel 2, in addition, is equipped with stiffening plate 41 on the vertical steel sheet, and stiffening plate 41 distributes around girder steel 2.
