Abstract
The utility model discloses a kind of steel beam flange opening strengthening construction using welding riser.Including girder steel and riser, in the equal perforate in the top flange of girder steel and lower flange, riser is fixed with opening porose flange surfaces, by carrying out reinforcement at riser device to hole；The outer of top flange lower surface on the outside of hole is equipped with riser, and the outer of the lower flange upper surface on the outside of hole is equipped with riser.The utility model simple structure, girder steel is set to have obtained reinforcement by welding riser near the hole of lower flange on girder steel, ensure that the girder steel bearing capacity after punching is not less than the bearing capacity before punching, while local buckling occurs in the edge of a wing for alleviating the stress concentration phenomenon of hole location and avoiding being weakened.
Description
Technical field
A kind of steel beam flange opening strengthening construction using welding riser is the utility model is related to, belongs to architectural engineering neck
Domain, can be widely applied to all kinds of steel buildings.
Background technology
To meet requirement of the building using function, it will usually in the steel beam opening of agent structure.The presence of hole makes steel
Beam net section reduces, and reduces the bearing capacity of girder steel, and common processing method is to carry out reinforcement to the position that punches in engineering.It is existing
《Technical Specification for Steel Structure of Tall Buildings》(JGJ99-2015) circular hole is opened steel beam web plate to give using annular ribbed stiffener
Strengthen, the measure that casing is strengthened or annular stiffening plate is strengthened；Open web rectangular opening and give orifice edge using longitudinal direction and horizontal stroke
The measure strengthened to ribbed stiffener.In residential housing, equipment installation generally requires exposed with guarantor so as to avoid through steel beam flange
It is beautiful to demonstrate,prove interior architecture, since specification does not have relevant regulation, directly punches in most cases on the edge of a wing without taking
Any technical measures, this stress performance to girder steel bring adverse effect.
Utility model content
In order to solve the problems, such as present in background technology, the utility model provides a kind of girder steel wing strengthened using riser
Edge reinforcement for openings constructs, and can effectively reduce the influence that the edge of a wing punches to girder steel stress performance, while simple structure, facilitate scene to apply
Work.
The technical solution adopted in the utility model is：
The utility model includes girder steel and riser, in the equal perforate in the top flange of girder steel and lower flange, to meet equipment installation
The needs passed through；Riser is fixed with opening porose flange surfaces, by carrying out reinforcement at riser device to hole.The edge of a wing is compensated with riser
Punch lost area, and riser is arranged on side of the hole edge away from steel beam web plate.
The riser is welded to flange surfaces.
In the top flange of girder steel the same side and lower flange perforate, and the hole of top flange is located at directly over the hole of lower flange.
The outer of top flange lower surface on the outside of hole is equipped with riser, and the outer of the lower flange upper surface on the outside of hole is equipped with
Riser.
The riser is more than bore dia along the length of girder steel extending direction.
The girder steel uses H profile steel beam.
The technical principle of the utility model is：1st, punch to the edge of a wing area of loss of riser is compensated, girder steel section
It is strong before can accomplishing and punching etc..2nd, the presence of riser can mitigate the stress concentration phenomenon on hole periphery.3rd, the weakening on the edge of a wing can
Flange plate can be caused local buckling occur, and the riser for being arranged on overhanging section of the edge of a wing has certain bending stiffness, can play
The effect put more energy into the edge of a wing, therefore can effectively prevent the local buckling for the position flange plate that punches.
The beneficial effects of the utility model are：
1st, simple structure, site operation fast and easy are quality controllable.
2nd, girder steel is made to have obtained reinforcement by welding riser near the hole of lower flange on girder steel, it is ensured that the steel after punching
Load bearing beam power is not less than the bearing capacity before punching, while can alleviate the stress concentration phenomenon of hole location and avoid the wing being weakened
There is local buckling in edge.
Brief description of the drawings
Fig. 1 is structure chart at the girder steel section of the utility model construction.
Fig. 2 is view at the 1-1 of Fig. 1.
Fig. 3 is view at the 2-2 of Fig. 1.
In figure：Girder steel 1, riser 2, hole 3.
Embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples.
As shown in Figure 1, the utility model includes girder steel 1 and riser 2, girder steel uses H profile steel beam, in the upper of 1 side of girder steel
The equal perforate 3 in the edge of a wing and lower flange, and the hole 3 of top flange is located at directly over the hole 3 of lower flange, face above and below holes.
Be fixed with riser 2 in the flange surfaces for being provided with hole 3, as shown in figure 3, hole 3 compared to riser 2 closer to 1 web of girder steel,
Riser 2 is arranged parallel to 1 web direction of girder steel.
Riser 2 specifically is welded with the outer of the top flange lower surface in the outside of hole 3, the lower flange upper table in the outside of hole 3
The outer in face is welded with riser 2, as shown in Fig. 2, riser 2 is more than 3 diameter of hole along the length of 1 extending direction of girder steel.
Thus structure is implemented, the area for the loss that punched with riser to the edge of a wing is compensated, and can mitigate hole periphery
Stress concentration phenomenon.The riser being arranged on has certain bending stiffness, plays the role of putting more energy into the edge of a wing, can effectively prevent
Only punch the local buckling of position flange plate.
