Abstract
The utility model discloses an anti-seismic structure column foot. The anti-seismic structure column foot comprises four wedge blocks and four reverse wedge blocks, wherein the four wedge blocks are mounted at the lower ends of four fixing nuts, and the four reverse wedge blocks are connected with the wedge blocks in a matched mode; every two reverse wedge blocks are correspondingly and fixedly connected to the two sides of one face of a steel angle through one flat-head spring; the steel angles are welded and fixed to a steel column frame foot flange. According to the anti-seismic structure column foot, the wedge blocks and the reverse wedge blocks arranged on bolts form a damping device, so that the gap, generated by plastic deformation of the bolts due to an earthquake, between the steel column frame foot flange and a foundation plane is effectively filled up, and the anti-pressure capacity of a steel structure is greatly improved; moreover, the anti-seismic structure column foot is simple in structure and easy to install, popularize and use.
Description
Technical field
The utility model belongs to steel work technique for fixing field, particularly a kind 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 purpose of this utility model is for addressing the above problem, and provides a kind of reasonable in design, and scientific structure is simple, can effectively compensate the antidetonation suspension column structure in the joint face gap causing because of earthquake.
The utility model is achieved in that earthquake resistant structure suspension column comprises 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.Bottom plate of steel column foot flange and base surface are bolted, angle steel is fixedly welded on bottom plate of steel column foot flange, two anti-wedges are one group, by tack spring correspondence, be fixedly connected on the both sides of angle steel, wedge be positioned at anti-wedge above, in the middle of wedge, be provided with a circular hole, wedge is placed on bolt by circular hole; In the middle of anti-wedge, be provided with a mounting hole, anti-wedge is placed on bolt by mounting hole; Four bolts insert 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.
Compared with prior art, it has following beneficial effect to the utility model:
The utility model antidetonation suspension column structure 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.

The specific embodiment
Embodiment:
Earthquake resistant structure suspension column as shown in Figure 1, Figure 2, Figure 3 and Figure 4, comprises 3,2 angle steel 4 of 4 wedges, 2,2 tack springs of 1,4 anti-wedges, 6,4 bolts 7 of 5,4 hold-down nuts of bottom plate of steel column foot flange, shaped steel pillar 8.Bottom plate of steel column foot flange 5 is connected by bolt 7 with base surface 9, angle steel 4 is fixedly welded on bottom plate of steel column foot flange 5, two anti-wedges 2 are one group, by tack spring 3 correspondences, be fixedly connected on the both sides of angle steel 4, wedge 1 be positioned at anti-wedge 2 above, in the middle of wedge 1, be provided with a circular hole 11, wedge 1 is placed on bolt 7 by circular hole 11; In the middle of anti-wedge 2, be provided with a mounting hole 21, anti-wedge 2 is placed on bolt 7 by mounting hole 21; Four bolts 7 insert in the through hole 10 of bottom plate of steel column foot flange 5 and base surface 9, screw four hold-down nuts 6 wedge 1 and anti-wedge 2 is fixing.
The utility model antidetonation suspension column structure 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 the utility model antidetonation suspension column structure, with respect to prior art, tool has an enormous advantage, and simple in structure, is convenient to implement.
Embodiment recited above is described preferred embodiment of the present utility model, not design of the present utility model and scope is limited.Do not departing under the prerequisite of the utility model design concept; various modification and improvement that this area ordinary person makes the technical solution of the utility model; all should drop into protection domain of the present utility model; the technology contents that the utility model is asked for protection, is all documented in claims.
