Detailed description of the invention
Below in conjunction with accompanying drawing illustrated embodiment, the present invention is further illustrated.
The present invention is in order to overcome the deficiencies in the prior art, and consider that tubular pillar-H-shaped girder connection is to the demand of ductility, power consumption, rigidity, oversized shape Memory Alloy member is applied to the connection of steel pipe column in steel framed structure-H-shaped beam, form a kind of tubular pillar-H-shaped beam connecting node had from recovery capacity and energy dissipation capacity, Figure 1 shows that its front view, Figure 2 shows that its top view.
Steel pipe column-H-shaped the girder connection comprising marmem bolt in the present invention comprises styletable assembly, beam-ends assembly, post connection end plate 7, beam connection end plate 8 and marmem bolt.Wherein, styletable assembly is the assembly including tubing string 2, is connected end plate 7 is connected with post; Beam-ends assembly is the assembly including H-shaped beam, is connected end plate 8 is connected with beam; Post connection end plate 7 connects in end plate 8 with beam corresponding installing hole, by loading marmem bolt wherein, styletable assembly is connected anchoring with beam-ends assembly, thus achieves the connection of steel pipe column 2 and H-shaped beam 13.Here beam connection end plate 8 is connected end plate 7 contact surface with post needs to do frosted process, meets design requirement to make contact surface friction factor.
Styletable assembly to be connected with tubing string by outer ring plate 1 or internal partition and to form, tubing string can be tubular pillar 2 and square tube post, coordinate circular or square through hole containing with the cross section of tubular pillar 2 or square tube post in outer ring plate 1 or internal partition, tubing string is welded in the through hole of outer ring plate 1 or internal partition; And the side that post connection end plate 7 is connected with beam-ends assembly at outer ring plate 1 or internal partition is attached thereto.
Beam-ends assembly can be H-shaped beam 13 itself, is connected end plate 8 is connected in the side that it is connected with styletable assembly with beam.
As can be seen from Fig. 1 and Fig. 2, this node side shown in front view comprises two marmem bolts, be respectively the first marmem bolt 4 and the second marmem bolt 12, corresponding connect end plate 8 at beam and to be connected this side in end plate 7 with post and to have two groups of corresponding installing holes, be respectively the first marmem bolt aperture 18 hole and the second marmem bolt aperture 21, as shown in Figure 4.The back side of side shown in this front view, connect at beam and sustained height that end plate 8 to be connected with post in end plate 7 comprises equally two groups of corresponding installing holes and two marmem bolts, be respectively the 3rd marmem bolt aperture 22 and the 4th marmem bolt aperture 25 and the 3rd marmem bolt 14 and the 4th marmem bolt.
Connect end plate 8 to prevent beam and is connected end plate 7 warpage with post, the both sides being connected end plate 7 at close beam connection end plate 8 with post are respectively provided with a slice stiffening rib, the first stiffening rib 3, second stiffening rib 5, the 3rd stiffening rib 9 and the 4th stiffening rib 11 as shown in Figure 1.
In the present invention, marmem bolt is positioned at beam and connects end plate 8 and to be connected on end plate 7 position outside the close beam wing with post, due to the super elastic characteristics of shape memory alloy material itself, these bolts have from recovery capacity, in order to resist the moment of flexure that girder steel passes over.
In order to strengthen the energy dissipation capacity of node of the present invention, in this steel pipe column-H-shaped girder connection, also comprise steel bolt.Corresponding, connect end plate 7 at post and to be connected installing hole end plate 8 is provided with for installing steel bolt with beam, be positioned at beam and connect end plate 8 and be connected position on end plate 7 inside the close beam wing with post, as the first steel bolt 6 and the second steel bolt 10 in Fig. 1.Under the external impacts such as seismic wave, allow steel bolt part to be destroyed, in repair process, only new steel bolt need be installed.
Outer ring plate 1 or internal partition are one of key members of the present invention, and its thickness can slightly higher than flange of beam thickness.
In the present invention, marmem bolt used comprises screw rod 17, nut 15 and packing ring 16, as shown in Figure 3.Wherein, screw rod 17 is processed by major diameter marmem; Nut and the very high steel (as No. 45 steel or 20 manganese titanium boron steels) of packing ring tensile strength make, and all will through Overheating Treatment to improve its intensity.Screw rod 17 pairs of Technologies for Heating Processing have higher requirement, and general needs carries out shrend after high temperature 400 DEG C insulation 30 minutes was to one hour.
In order to ensure that screw rod 17 has super-elasticity, the austenite phase transformation of the shape memory alloy material that screw rod 17 uses completes temperature should lower than environment temperature.The pretension of screw rod realizes by tighting a bolt.
In steel pipe column of the present invention-H-shaped girder connection, the welding that the welding of tubing string and outer ring plate 1 or internal partition, outer ring plate 1 or internal partition are connected the welding of end plate 7 with post, H-shaped beam 13 is connected end plate 8 with beam, beam connect end plate 8 is connected end plate 7 work such as bolt hole of opening with post and directly complete in factory, only need carry out tie-beam by marmem bolt and steel bolt at the scene and be connected end plate 8 and be connected end plate 7 with post.The order of connection of joint connection in site is: first connect steel bolt, then connect marmem bolt; Thus the assembling of beam column can be realized, form frame structure system.
Above-mentioned is can understand and apply the invention for ease of those skilled in the art to the description of embodiment.Person skilled in the art obviously easily can make various amendment to these embodiments, and General Principle described herein is applied in other embodiments and need not through performing creative labour.Therefore, the invention is not restricted to embodiment here, those skilled in the art, according to announcement of the present invention, do not depart from improvement that scope makes and amendment all should within protection scope of the present invention.
