The specific embodiment
The present invention is further illustrated below in conjunction with the accompanying drawing illustrated embodiment.
The present invention is in order to overcome the deficiencies in the prior art, and consider the demand of tubular pillar-H ellbeam node to ductility, power consumption, rigidity, oversized shape memorial alloy member is applied to the connection of steel pipe column in the steel framed structure-H ellbeam, form a kind of tubular pillar-H ellbeam connected node that has from recovery capacity and energy dissipation capacity, Figure 1 shows that its front view, Figure 2 shows that its vertical view.
Steel pipe column-H ellbeam the node that comprises the marmem bolt among the present invention comprises that styletable assembly, beam-ends assembly, post connect end plate 7, beam connects end plate 8 and marmem bolt.Wherein, the styletable assembly is the assembly that includes tubing string 2, is connected end plate 7 with post and links to each other; The beam-ends assembly is the assembly that includes the H ellbeam, is connected end plate 8 with beam and links to each other; Post connection end plate 7 connects in the end plate 8 with beam corresponding installing hole, by the marmem bolt of packing into therein the styletable assembly is connected anchoring with the beam-ends assembly, thereby has realized being connected of steel pipe column 2 and H ellbeam 13.Here beam connection end plate 8 is connected the contact surface of end plate 7 with post need do the frosted processing, so that the contact surface friction factor meets design requirement.
The styletable assembly is linked to each other with tubing string by outer ring plate 1 or internal partition and constitutes, tubing string can be tubular pillar 2 and square tube post, the cross section of containing in outer ring plate 1 or the internal partition with tubular pillar 2 or square tube post cooperates circular or square through hole, and tubing string is welded in the through hole of outer ring plate 1 or internal partition; And post connects end plate 7 and is attached thereto in the side that outer ring plate 1 or internal partition link to each other with the beam-ends assembly.
The beam-ends assembly can be a H ellbeam 13 itself, and side that links to each other at itself and styletable assembly is connected end plate 8 with beam continuous.
From Fig. 1 and Fig. 2 as can be seen, this node comprises two marmem bolts in side shown in the front view, be respectively the first marmem bolt 4 and the second marmem bolt 12, corresponding connect end plate 8 at beam and be connected the installing hole that this side in the end plate 7 has two groups of correspondences with post, be respectively the first marmem bolt aperture, 18 holes and the second marmem bolt aperture 21, as shown in Figure 4.The back side in side shown in this front view, connect end plate 8 at beam and be connected installing hole and two the marmem bolts that comprise two groups of correspondences on the sustained height in the end plate 7 equally with post, 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.
In order to prevent that beam from connecting end plate 8 and being connected end plate 7 warpages with post, respectively be provided with a slice stiffening rib, as shown in Figure 1 first stiffening rib 3, second stiffening rib 5, the 3rd stiffening rib 9 and the 4th stiffening rib 11 in the both sides that are connected end plate 7 near beam connection end plate 8 with post.
The marmem bolt is positioned at beam connection end plate 8 is connected the close beam wing outside on the end plate 7 with post position among the present invention, because 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, also comprise the steel bolt in this steel pipe column-H ellbeam node.Corresponding, connect end plate 7 at post and is connected with beam and is provided with the installing hole that is used to install the steel bolt on the end plate 8, be positioned at beam and connect end plate 8 is connected close beam wing inboard on the end plate 7 with post position, as the first steel bolt 6 among Fig. 1 and the second steel bolt 10.Under external impacts such as seismic wave, allow steel bolt part destroyed, only need that in repair process new steel bolt is installed and get final product.
Used marmem bolt comprises screw rod 17, nut 15 and packing ring 16 among the present invention, as shown in Figure 3.Wherein, screw rod 17 is processed by the major diameter marmem; Nut and packing ring are made of the very high steel of tensile strength (as No. 45 steel or 20 manganese titanium boron steels), and all will be through Overheating Treatment to improve its intensity.17 pairs of Technologies for Heating Processing of screw rod have higher requirement, generally need carry out shrend after 400 ℃ of high temperature insulation 30 minutes was to one hour.
In order to guarantee that screw rod 17 has super-elasticity, the austenite phase transformation of screw rod 17 employed shape memory alloy materials is finished temperature should be lower than environment temperature.The pretension of screw rod is realized by tighting a bolt.
In steel pipe column of the present invention-H ellbeam node, tubing string and welding, outer ring plate 1 or the internal partition of outer ring plate 1 or internal partition are connected the welding of end plate 7, H ellbeam 13 is connected end plate 8 with beam welding, beam and connect end plate 8 is connected end plate 7 with post the work such as bolt hole of opening and directly finish in factory with post, a need comes tie-beam to be connected end plate 8 by marmem bolt and steel bolt to be connected end plate 7 with post and to get final product at the scene.The on-the-spot order of connection that connects is: connect the steel bolt earlier, connect the marmem bolt again; Thereby can realize the assembling of beam column, form frame structure system.
The above-mentioned description to embodiment is can understand and apply the invention for ease of those skilled in the art.The person skilled in the art obviously can easily make various modifications to these embodiment, and needn't pass through performing creative labour being applied in the General Principle of this explanation among other embodiment.Therefore, the invention is not restricted to the embodiment here, those skilled in the art are according to announcement of the present invention, and not breaking away from the improvement that category of the present invention makes and revise all should be within protection scope of the present invention.
