Abstract
The invention discloses a porous wire passing steel beam, which comprises a steel beam and reinforcing rings, wherein a plurality of wire passing holes are formed in the steel beam; each reinforcing ring comprises an inner ring and an outer ring; each outer ring outwards extends from one end of the corresponding inner ring in the radial direction; the two reinforcing rings are oppositely arranged in the wire passing holes; the outer circle surface of each inner ring is in contact with the inner circle surface of the corresponding wire passing hole; the side surface of each outer ring is in contact with the surface of the steel beam; and one ends, far away from the outer rings, of the two inner rings are welded and connected. The reinforcing rings are adopted for enhancing the strength in positions of the wire passing holes, and the deformation in the positions of the wire passing holes is prevented. The inner rings support the inner surfaces of the wire passing holes; the outer rings limit the positions of the inner rings; the relative movement of the inner rings and the wire passing holes is prevented; and the structural stability of the porous wire passing steel beam is improved.
Description
Technical field
The present invention relates to the realm of building construction, particularly relate to a kind of girder steel.
Background technology
In current the realm of building construction, especially in long span building work progress, girder steel is usually selected to bear Main Load.
The cable that interior of building is buried underground needs to get around girder steel usually, and when getting around girder steel, needs to offer through wires hole on girder steel.Through wires hole offered by girder steel, can impact the overall force-bearing situation of girder steel.The through wires hole diameter offered is larger, also larger on the impact of the overall force-bearing situation of girder steel, therefore, needs the reinforcement measure considering through wires hole place.
Summary of the invention
Namely object of the present invention is providing a kind of bulk strength much higher hole threading girder steel.
Object of the present invention is achieved through the following technical solutions:
A kind of porous threading girder steel, comprises girder steel, girder steel offers multiple through wires hole; Also comprise reinforcing ring, reinforcing ring comprises inner ring and by inner ring one end outward extending outer shroud in radial directions; Two reinforcing rings are relatively arranged in through wires hole, and the periphery of inner ring contacts with the inner headed face of through wires hole, the side of outer shroud and the surface contact of girder steel; Two inner ring are welded to connect away from one end of outer shroud.
The girder steel offering through wires hole is after coming into operation, and due to the effect of load, through wires hole place can deform, and the inside crimp of hole wall of through wires hole, causes girder steel bulk strength to decline.Therefore, reinforcing ring is set, to increase the intensity at through wires hole place, prevents through wires hole place to be out of shape.The inner surface of inner ring to through wires hole supports, and outer shroud carries out spacing to inner ring, prevents inner ring and through wires hole generation relative motion, improves structural stability of the present invention.
Further, described inner ring offers bevel for welding away from one end of outer shroud.
Further, the inner headed face of described through wires hole offers stopper slot, and the periphery of described inner ring is provided with in spacing preiection corresponding to stopper slot.
Stopper slot and spacing preiection are set, prevent inner ring and through wires hole from relatively rotating, improve structural stability of the present invention.
Further, described stopper slot is two groups, and two groups of stopper slots lay respectively at the two ends of described through wires hole.
Stopper slot is divided into two groups, reduces the area at through wires hole inner surface fluting, thus the impact of stopper slot on girder steel intensity is down to minimum.
Further, described outer shroud is provided with hemisphere jut near the side of described girder steel, and described inner ring offers triangular groove near the terminal interior surface of described outer shroud, and the cross section of triangular groove is triangle.
When installing reinforcing ring, the spacing on two reinforcing rings between outer shroud is difficult to accomplish that the thickness with girder steel is completely the same.In order to eliminate the gap between outer shroud and girder steel, offer triangular groove.When welding reinforcing ring, reinforcing ring expanded by heating, the weak section distortion that triangular groove place is formed, two outer shrouds slope inwardly, thus contact with girder steel.Hemisphere jut is set, avoids outer shroud periphery corner to contact the stress concentration phenomenon caused with girder steel and occur.
In sum, advantage of the present invention and beneficial effect are:
1. reinforcing ring is set, to increase the intensity at through wires hole place, prevents through wires hole place to be out of shape;
2. the inner surface of inner ring to through wires hole supports, and outer shroud carries out spacing to inner ring, prevents inner ring and through wires hole generation relative motion, improves structural stability of the present invention;
3. stopper slot and spacing preiection are set, prevent inner ring and through wires hole from relatively rotating, improve structural stability of the present invention;
4. stopper slot is divided into two groups, reduces the area at through wires hole inner surface fluting, thus the impact of stopper slot on girder steel intensity is down to minimum;
5. offer triangular groove.When welding reinforcing ring, reinforcing ring expanded by heating, the weak section distortion that triangular groove place is formed, two outer shrouds slope inwardly, thus contact with girder steel, eliminate the gap between outer shroud and girder steel;
6. arrange hemisphere jut, hemisphere jut contacts with girder steel, avoids outer shroud periphery corner to contact the stress concentration phenomenon caused with girder steel and occurs.
