Abstract
The invention discloses a method for manufacturing an aseismic structure column foot. The method includes the steps that four wedge blocks, four reverse wedge blocks, two flat head springs, two steel angles, a steel column foot base plate flange, four set screw nuts, four bolts and a section steel column are manufactured; two reverse wedge blocks constitute a group and are correspondingly and fixedly connected to the two sides of the steel angles through the flat head springs, the wedge blocks are placed on the reverse wedge blocks, the wedge blocks are arranged on the bolts in a sleeved mode through circular holes, and the reverse wedge blocks are arranged on the bolts in a sleeved mode through kidney-shaped holes; the four bolts are inserted into through holes of the steel column foot base plate flange and through holes of a base surface, and the four set screw nuts are screwed to enable the wedge blocks and the reverse wedge blocks to be fixed. By means of the aseismic structure column foot manufactured through the method, the gap between the steel column foot base plate flange and the base surface due to bolt plastic deformation caused by earthquakes can be effectively filled through a damping device which is composed of the wedge blocks and the reverse wedge blocks arranged on the bolts, the anti-pressure ability of a steel structure is greatly improved, the structure is simple, and mounting, using and popularizing are easy.
Description
Technical field
The invention belongs to steel work technique for fixing field, be specifically related to a kind of manufacture method of earthquake resistant structure suspension column.
Background technology
At present steel work, with its good ductility and shock resistance in earthquake region is built, occupied very large proportion, and its earthquake main manifestations is destruction, the destruction of member and 3 kinds of forms of the total Collapse of structure that node connects.The set bolt of common exposed type steel column foot bottom flange and base surface or joint face can rock and cause plastic strain because of earthquake, and then can make steel column pin and joint face occur gap, thereby it is moving in the seismic load of repeated action, to produce idle running, the destruction of causing steel column pin.
Summary of the invention
The object of the invention is for addressing the above problem, provide a kind of reasonable in design, scientific structure is simple, can effectively compensate the manufacture method of the earthquake resistant structure suspension column in the joint face gap causing because of earthquake.
Concrete steps are:
(1) make 4 wedges, 4 anti-wedges, 2 tack springs, 2 angle steel, bottom plate of steel column foot flange, 4 hold-down nuts, 4 bolts, shaped steel pillar.In the middle of wedge, be provided with a circular hole, in the middle of anti-wedge, be provided with a mounting hole.
(2) bottom plate of steel column foot flange and base surface are bolted, and angle steel is fixedly welded on bottom plate of steel column foot flange.
(3) two anti-wedges are one group, are fixedly connected on the both sides of angle steel by tack spring correspondence, wedge be positioned at anti-wedge above, wedge is placed on bolt by circular hole; Anti-wedge is placed on bolt by mounting hole.
(4) four bolts are inserted in the through hole of bottom plate of steel column foot flange and base surface, screw four hold-down nuts wedge and anti-wedge are fixed.
Antidetonation suspension column structure of the present invention is when design and installation, need to be applicable to according to the manufacture of steel column pin wedge and the anti-wedge in the hole of corresponding bolt size, according to distance between set bolt, manufacture the tack spring of the certain elastic force of certain length simultaneously, during installation, for guaranteeing that anti-wedge maximizes bottom plate of steel column foot flange that compensation produces because of earthquake and the gap between basic joint face, anti-wedge need be compressed to the limit of kidney-shaped piece mouth.An anti-seismic performance that can greatly improve steel column pin and even whole steel work integral body by antidetonation suspension column structure of the present invention, with respect to prior art, tool has an enormous advantage, and simple in structure, is convenient to implement.
Compared with prior art, it has following beneficial effect in the present invention:
Earthquake resistant structure suspension column of the present invention is by being arranged at wedge and this damping device of anti-wedge at steel column pin set bolt position, improved greatly the anti-seismic performance of steel column pin, after the plastic strain of earthquake hospital guide bolt, there is gap in steel column pin and base plate, anti-wedge is due to the effect of acting force of the spring, instant compensation, the in the situation that of having avoided in unloading and reloaded, the empty rotation situation that steel column pin occurs.
