Abstract
The invention belongs to the field of building structures and particularly relates to a column base joint with double defense shear-resistant keys and a construction method thereof. A steel structure column base joint consists of two shear-resistant split systems; a second defense shear-resistant key is free of load in the normal using stage; when the column base joint suffers from extreme disasters and a first defense shear-resistant system is damaged, the second defense shear-resistant key takes effect instantly, so that the continuous damage to the column base joint is avoided. Through the technical scheme, the safety redundancy degree of the steel structure column joint is improved; a certain energy-dissipation effect is also achieved; meanwhile, the second defense shear-resistant key is simple to process and manufacture and convenient to mount.
Description
Technical field
The invention belongs to building structure field, be specifically related to a kind of band two roads and set up defences the foot joint of shear key and construction method thereof.
Background technology
Steel building compares traditional architecture, has that the strength of materials is high, anti-seismic performance good, environmental protection, is convenient to the aspect advantages such as suitability for industrialized production, be widely used in industry, civilian construction.In steel building, foot joint, as the coupling part of superstructure and infrastructure, plays the effect of forming a connecting link, particularly important to the safety of structure.If foot joint destroys, imponderable loss will be caused.Therefore not only to ensure that steel work foot joint has enough degrees of safety in the design stage, and do special protection in construction and operational phase reply suspension column.
In recent years, terrorist activity spreads in the world, due to steel work suspension column closely face, and is subject to Vehicular impact and the blast impulse of the attack of terrorism.And steel building also may meet with the rarely occurred earthquake higher than this area fortification intensity in-service, geological process is the repeatedly reciprocating impact to structure, accumulating will be caused to destroy to foot joint;
What adopt in conventional steel structure foot joint is welded to connect, and because weld stress is concentrated with wood property uneven, under the reciprocating impact effect of above-mentioned extreme disaster, may bring out brittle fracture.If foot joint only has shearing resistance system of setting up defences together, once after destroying, following one by one lasting earthquake or blast impulse cannot be resisted.Therefore the applicant provides a kind of band two roads to set up defences the foot joint of shear key and construction method thereof, and this case produces thus.
Summary of the invention
The object of the present invention is to provide a kind of band two roads to set up defences the foot joint of shear key and construction method thereof, steel work foot joint is made up of a twice shearing resistance point system.
For achieving the above object, the concrete disclosed technical scheme of the present invention is: setting up defences the foot joint of shear key in a kind of band two roads, comprises basis, be 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; Be distributed with crashproof bracket and two roads in described steel column to set up defences shear key, wherein, two roads shear key of setting up defences is positioned at crashproof bracket and leaves certain interval.
Further, set up defences shear key and crashproof bracket of described two roads cooperatively interacts and is connected in cross distribution; Or, described two roads set up defences shear key be well word distribution, described crashproof bracket circumferentially disperses distribution.
Further, described finished product bearing comprises upper bracket, the undersetting of mutual clamping, 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.
Setting up defences the construction method of foot joint of shear key in band two roads, specifically comprises the steps: step one, complete burying underground of built-in fitting, and carry out pouring & maintenance to base concrete and complete; Step 2, finished product bearing and built-in fitting firm welding, and temporary fixed, set up defences the upper bracket plate firm welding of shear key and finished product bearing in two roads; Step 3, steel column hoisted in position, and temporary fixed, setting up defences gap between shear key in the crashproof bracket of adjustment steel column and two roads, ensures that gap meets design requirement, adjust complete after steel column and finished product bearing upper bracket plate are welded and fixed; Step 4, after structural entity installation, remove the temporary fixed plate of finished product bearing, structural entity unloads.In the design stage, two roads shear key of setting up defences should be thrown off completely with foot joint, and reserved appropriate clearance, both guarantees do not collide at serviceability limit stage; Two roads shear key of setting up defences can adopt single shear key, also can adopt multiple shear keies of dispersion; Set up defences shear key cross section and attachment weld size of two roads should be determined according to designing and calculating; The gap set up defences between shear key in steel work 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 assembled in advance with foot joint, ensure field erected required precision; The anticorrosion way of shear key is set up defences in two roads should be consistent with main body steel work; The assembled entity that adopts is assembled or virtual assembled in advance in advance in advance.
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 subsurface work acceptance in time; Next process can be carried out after acceptance(check).
Steel work foot joint hoisted in position, and temporary fixed, setting up defences gap between shear key in adjustment foot joint and two roads, ensures that gap meets design requirement; After adjustment, foot joint is welded and fixed.
Beneficial effect of the present invention:
Second shear key of setting up defences does not bear 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, prevents foot joint from occurring to destroy continuously;
This technical scheme improves the unnecessary degree of safety of steel work foot joint, another fixed power consumption effect; Simultaneously two roads set up defences shear key processing and manufacturing simple, install convenient.
