Description
Technical field
This utility model belongs to building structure field, is specifically related to the foot joint of a kind of shear key of setting up defences with two roads.
Background technology
Steel building compares traditional architecture, has that strength of materials height, anti-seismic performance be good, environmental protection, is easy to the aspect advantages such as industrialized production, has been widely used in industry, civil buildings.In steel building, foot joint, as the coupling part of superstructure Yu infrastructure, plays the effect formed a connecting link, and the safety of structure is particularly important.If foot joint destroys, will result in imponderable loss.Therefore not only to ensure that steel construction foot joint has enough degrees of safety in the design phase, and do special protection in construction and operational phase reply suspension column.
In recent years, terrorist activity spreads in the world, due to steel construction suspension column closely face, and is subject to Vehicular impact and the blast impulse of the attack of terrorism.And steel building is likely to in-service and meets with the rarely occurred earthquake higher than this area fortification intensity, geological process is the repeatedly reciprocating impact to structure, it will cause accumulating to destroy foot joint；
What adopt in conventional steel structure foot joint is welded to connect, and concentrates due to weld stress and material is uneven, under the reciprocating impact effect of above-mentioned extreme disaster, it is possible to bring out brittle fracture.If foot joint only has shearing resistance system of setting up defences together, once after destroying, will be unable to resist following one by one lasting earthquake or blast impulse.Therefore the applicant provides the foot joint of a kind of shear key of setting up defences with two roads, and this case thus produces.
Utility model content

For achieving the above object, this utility model specifically disclosed technical scheme is: the foot joint of a kind of shear key of setting up defences with two roads, including basis, is provided with built-in fitting in basis, built-in fitting is provided with finished product bearing, the upper bracket plate on finished product bearing is provided with steel column；Distribution has crashproof bracket and two roads to set up defences shear key in described steel column, and wherein, two roads shear key of setting up defences is positioned at crashproof bracket and leaves certain interval.
Further, shear key is set up defences and crashproof bracket cooperates connection in cross distribution in described two roads；Or, described two roads set up defences shear key be well word distribution, described crashproof bracket circumferentially disperses distribution.
Further, described finished product bearing includes the upper bracket of mutual clamping, undersetting, and is flexibly connected the middle spacer of upper bracket and undersetting；Wherein the arc surface of middle spacer is flexibly connected with the concave surface of undersetting, and the horizontal plane of middle spacer abuts with upper bracket.
The construction method of foot joint of a kind of shear key of setting up defences with two roads, specifically includes following steps: step one, completes burying underground of built-in fitting, and base concrete is built and maintenance completes；Step 2, finished product bearing and built-in fitting firm welding, and fix, set up defences the shear key upper bracket plate firm welding with finished product bearing in two roads temporarily；Step 3, steel column hoisted in position, and temporarily fixing, adjusts the crashproof bracket of steel column and sets up defences gap between shear key in two roads, it is ensured that gap meets design requirement, adjust complete after steel column and finished product bearing upper bracket plate are welded and fixed；Step 4, after structure integral installation completes, removes finished product bearing and fixes plate temporarily, and structure entirety unloads.In the design phase, shear key is set up defences in two roads should be completely disengaged with foot joint, and reserved appropriate clearance, it is ensured that both do not collide at serviceability limit stage；Two roads shear key of setting up defences can adopt single shear key, also can adopt scattered multiple shear key；Are set up defences in shear key cross section in two roads and attachment weld size should be determined according to designing and calculating；The gap set up defences between shear key in steel construction foot joint and two roads should be 5mm；Shear key correspondence position of setting up defences in two roads should arrange crashproof bracket or crashproof stiffener.
Shear key is set up defences before dispatching from the factory in two roads, should carry out pre-assembly with foot joint, it is ensured that field erected required precision；Shear key anticorrosion way is set up defences in two roads should be consistent with main body steel construction；Pre-assembly can adopt entity assembled in advance or virtual pre-assembly.
Two roads shear key of setting up defences has welded with bottom built-in fitting or finished product bearing, and weld size should meet design requirement；Two roads are set up defences after shear key welded, and should carry out acceptance of concealed work in time；Next process can be carried out after acceptance(check).
Steel construction foot joint hoisted in position, and temporarily fixing, adjusts foot joint and sets up defences gap between shear key in two roads, it is ensured that gap meets design requirement；After adjustment, foot joint is welded and fixed.
This utility model beneficial effect:
Second shear key of setting up defences does not undertake any load at serviceability limit stage；When foot joint meets with extreme disaster, first is set up defences after shearing resistance system goes to pot, and second shear key of setting up defences plays a role immediately, it is prevented that foot joint occurs to destroy continuously；
This technical scheme improves the unnecessary degree of safety of steel construction foot joint, another fixed power consumption effect；Set up defences in two roads simultaneously, and shear key processing and manufacturing is simple, it is convenient to install.
