Description
Technical field
The present invention relates to the realm of building construction, relate in particular to a kind of girder steel through wires hole reinforced structure.
Background technology
In current the realm of building construction, especially, in long span building work progress, conventionally select girder steel to bear Main Load.
The cable that interior of building is buried underground need to get around girder steel conventionally, and in the time cannot getting around girder steel, need on girder steel, offer through wires hole.On girder steel, offer through wires hole, can impact the overall force-bearing situation of girder steel.The through wires hole diameter of offering is larger, and the impact of the overall force-bearing situation on girder steel is also larger, and through wires hole place easily produces distortion, thereby the cable in through wires hole is caused to extruding.Therefore, need to consider the reinforcement measure at through wires hole place.
Summary of the invention
Object of the present invention is to provide a kind of girder steel through wires hole reinforced structure that improves porous girder steel intensity.
Object of the present invention is achieved through the following technical solutions:
Girder steel through wires hole reinforced structure, comprises girder steel, offers multiple through wires holes on girder steel, and through wires hole inner surface offers internal thread; Also comprise reinforcing ring, reinforcing ring comprises outer shroud, interior ring and joint pin, interior ring is positioned at outer shroud scope and both are concentric, one end of joint pin is connected with the inner surface of outer shroud, the other end of joint pin is connected with the external surface of interior ring, the external surface of outer shroud is provided with external screw thread, outer shroud and through wires hole threaded engagement.
Offer the girder steel of through wires hole after coming into operation, due to the effect of load, through wires hole place can deform, and the inside crimp of hole wall of through wires hole, causes extruding to the cable in through wires hole.Therefore, reinforcing ring is set.Reinforcing ring comprises the double-layer structure being made up of outer shroud and interior ring.Outer shroud is for being threaded with through wires hole, easy to assembly.Interior ring, for maintaining the circular configuration in through wires hole, prevents because through wires hole distortion causes extruding to the cable in through wires hole.
Further, described joint pin is arranged in a crossed manner.
Joint pin is arranged in a crossed manner, can effectively improve structural strength and the supporting capacity of reinforcing ring.
Further, described outer shroud comprises to the annular channel-section steel A of internal recessing and the annular channel-section steel B outwards slotting, and the groove of annular channel-section steel A and annular channel-section steel B is oppositely arranged, and annular channel-section steel A and annular channel-section steel B are welded to connect; The external surface of annular channel-section steel A is provided with external screw thread, and annular channel-section steel A is threaded with described through wires hole, and the inner surface of annular channel-section steel B is connected with described joint pin.
In the time that through wires hole has distortion, through wires hole inwall can push outer shroud, causes stress to concentrate, and causes outer shroud to damage if extruding force is crossed senior general, and the load that outer shroud bears is passed to interior ring by joint pin, also may cause interior ring to damage.For this reason, outer shroud is arranged to the hollow-core construction being combined by annular channel-section steel A and annular channel-section steel B, make outer shroud easily deformable in the time of bearing load, thereby avoid load to be passed to interior ring, to maintain the circular configuration in through wires hole, further prevent because through wires hole distortion causes extruding to the cable in through wires hole.
Further, the both sides of described annular channel-section steel A and annular channel-section steel B expand outwardly.
The both sides of annular channel-section steel A and annular channel-section steel B expand outwardly, and outer shroud is subject in the time being subject to the extruding of through wires hole inwall, the generation radial deformation that can be more prone to, thereby the suffered load of ring in further reducing.
In sum, advantage of the present invention and beneficial effect are:
1. the present invention arranges reinforcing ring, reinforcing ring comprises the double-layer structure being made up of outer shroud and interior ring, and outer shroud is for being threaded with through wires hole, easy to assembly, interior ring, for maintaining the circular configuration in through wires hole, prevents because through wires hole distortion causes extruding to the cable in through wires hole;
2. joint pin is arranged in a crossed manner, can effectively improve structural strength and the supporting capacity of reinforcing ring;
3. outer shroud is arranged to the hollow-core construction being combined by annular channel-section steel A and annular channel-section steel B, make outer shroud easily deformable in the time of bearing load, thereby avoid load to be passed to interior ring, to maintain the circular configuration in through wires hole, further prevent because through wires hole distortion causes extruding to the cable in through wires hole;
4. the both sides of annular channel-section steel A and annular channel-section steel B expand outwardly, and outer shroud is subject in the time being subject to the extruding of through wires hole inwall, the generation radial deformation that can be more prone to, thereby the suffered load of ring in further reducing.
