Description
Technical field:
The present invention relates to building field, relate in particular to supporting member in the civil engineering, particularly newly-built or reinforce used support member in the construction work, particularly a kind of all steel is made the buckling-restrained support of double hose.
Background technology:
In civil engineering; Guarantee rigidity, intensity and ductility through the wind resistance anti-seismic performance that strengthens braced structures itself in the wind resistance seismic design; But flexing takes place during this braced structures pressurized easily part-structure is deactivated, reduce the anti-side rigidity of structure, cause the load of other part to increase; Malformation increases, and is very unfavorable to structure.Thereby buckling-restrained braced structures is a kind of pressurized can flexing not drawn the braced structures that all can surrender with pressurized, has stable, full hysteresis performance.The application of lightweight buckling-restrained bracing member can improve when traditional supporting member receives axial compression the shortcoming of flexing can take place, in case efficiently solve the problem that the rigidity of structure is degenerated rapidly after the common support flexing, has guaranteed the anti-seismic performance of structure under big shake effect.In addition, utilizing steel after surrender, to have endergonic characteristic, make buckling-restrained support be not only supporting member, also is a kind of power consumption member of superior performance, the reaction in the time of can reducing structure effectively and receive earthquake.
The U.S. begins to gradually adopt buckling-restrained support after California north mountain range earthquake in 1994, buckling-restrained support frame system has been worked out method for designing and standard, with the seismic design foundation as this kind structural system.After Japan's nineteen ninety-five the big earthquakes in Osaka and Kobe, also begin widely with the power consumption member of buckling-restrained support as structural seismic.Ground such as the Shanghai of China, Beijing, Taiwan have many buildings now and have also adopted buckling-restrained support.The buckling-restrained U.S. and the Japan of being supported on is referred to as not have bonding and supports (Unbonded Brace), is referred to as buckling-restrained support or anti-flexing at home and supports (BucklingRestrained Brace).
In the prior art; The lightweight buckling-restrained bracing member is made up of kernel steel supporting component and outside steel pipe concrete; The kernel steel supporting component adopts yi word pattern or cross steel plate more; Concrete in the outside steel pipe concrete partly is after treating that kernel steel supporting component and outside steel pipe fix the position, to water, vibrate.Because the structure relative complex of self, traditional lightweight buckling-restrained bracing member comes with some shortcomings: (1) adopts concrete or mortar as packing material, and grouting operation is difficulty relatively.In the actual engineering, lightweight buckling-restrained bracing member length is generally all more than 4 meters.At this moment, should guarantee that concrete or mortar are closely knit, guarantee that again the relative position of outer steel pipe and kernel steel supporting component can not squint, be the comparison difficulty, checks and accepts, checks difficult especially; (2) from great, transportation, installation be difficulty relatively.The member that tonnage is bigger, because himself cross section is bigger, deadweight tends to reach more than 1 ton, even several tons, be not easy to transportation and engineering site installation.(3) the processing and fabricating cost is higher.
Summary of the invention:
The object of the present invention is to provide a kind of all steel to make the buckling-restrained support of double hose, described this all steel make the buckling-restrained support of double hose to solve lightweight buckling-restrained bracing member construction in the prior art inconvenient, be not easy to check, weight is big, cost is high technical problem.
This all steel of the present invention is made the buckling-restrained support of double hose and is made up of kernel steel supporting component, non-cohesive material layer and outer tube member; Wherein, Described kernel steel supporting component and outer tube member are made up of steel cylindrical tube respectively; The kernel steel supporting component is arranged on the inside of outer tube member; Described non-cohesive material layer covers and is bonded on the outer circle wall of kernel steel supporting component; Be provided with the gap between the inwall of non-cohesive material layer and outer tube member, be fixedly welded with a cross connection steel plate in the two ends of kernel steel supporting component separately, the radial section of any described cross connection steel plate all is cross; Any cross connection steel plate all along the kernel steel supporting component axially, outside the two ends of kernel steel supporting component, extend; The diameter of the radial section of cross connection steel plate extension is greater than the internal diameter of kernel steel supporting component, and the two ends of kernel steel supporting component and the two ends of outer tube member are welded with head plate, and cross connection steel plate extension is provided with the connecting bolt hole of two above numbers.
Further, the central axes of the central axis of described kernel steel supporting component and outer tube member.
Further, described non-cohesive material layer constitutes by polytetrafluoroethylene film, polyvinyl chloride film, polyethylene sheeting or grease release agent are compound.
Further, the gap between the inwall of non-cohesive material layer and outer tube member is 1～3mm.
Further; The axial middle part of kernel steel supporting component and outer tube member is provided with radially circular hole; Be provided with a steel cylinder in the described radially circular hole; Described steel cylinder runs through kernel steel supporting component and outer tube member along the diameter of kernel steel supporting component and outer tube member, and the outer wall welding of cylindrical two ends of steel and outer tube member is fixing.
Further, the steel pipe trade mark in described kernel steel supporting component and the outer tube member is Q235, Q345, Q390, Q420,10,15 or 20.
The present invention and prior art are compared, and its effect is actively with tangible.The present invention adopts the kernel steel supporting component to support as kernel, and inner tube portion is overhanging section, is made up of cross connection steel plate for overhanging section, and cross connection steel plate is near outer tunnel end location variable cross-section, and in extending in the pipe.In the pipe mid portion be constraint surrender section, the position that inner tube portion is strengthened by cross connection steel plate is the non-surrender section of constraint, overhanging section for not retraining non-surrender section.Interior pipe and outer tube are pipe, selection, buying, easy to process, and the process-cycle is short, and adding only needs the blanking cutting man-hour, and the welding job amount is little; From heavy and light, easy transportation and installation, comprehensive cost is lower than traditional lightweight buckling-restrained bracing member.Simple structure of the present invention, bearing capacity height, good looking appearance, easy to process, cheap can be used for civilian construction, industrial construction, public building and bridge engineering etc.
