Description

Building steel construction fossil fragments connection structure Technical Field The utility model relates to the technical field of building keels, in particular to a building steel structure keel connecting structure. Background The keel is a building material for supporting a modeling and fixing structure, is widely applied to places such as hotels, passenger stations, theatres, markets, factories, indoor decoration settings, ceilings and the like, is a decorated framework and a base material, is very common in use, has various types, and can be divided into wood keels, light steel keels, aluminum alloy keels, steel keels and the like according to different manufacturing materials. The floor system is divided according to the use parts and can be divided into a suspended ceiling keel, a vertical wall keel, a ground laying keel, a suspended keel and the like; The steel structure keels are quite common in application and are fixed into different sizes and shapes through threaded connection, but bolts required by a conventional threaded fixing mode are more, disassembly and assembly are quite complicated, the reserved butt joint holes of the existing keels are formed in fixed positions when the existing keels are adjacently butted, the angles after the existing keels are butted are only vertical or horizontal, the requirements of multi-angle erection of the keels between different buildings cannot be met, and the applicability is poor. Disclosure of utility model The utility model aims to provide a building steel structure keel connecting structure which can flexibly erect steel frames at multiple angles and rotate, limit and fix the steel frames to finish quick butt joint, thereby being applicable to the requirements of multi-angle erection among different keels, improving the flexibility and comprehensiveness of butt joint, providing a more complex combination mode and being applied to more various erection environments. To achieve the above object, there is provided a construction steel structure keel connecting structure comprising: the right side frame of first steelframe is equipped with the second steelframe, the left side center department of first steelframe has seted up the annular, sliding fit has the locating shaft about in the annular, the right-hand member and the second steelframe fixed connection of locating shaft, a plurality of first angle modulation jack and second angle modulation jack have been seted up through annular array respectively in the center department of one side opposite to first steelframe and second steelframe, the left side frame of first angle modulation jack is equipped with the cardboard, symmetrical about the right side of cardboard is fixed with the locking lever, the locking lever all runs through first angle modulation jack and second angle modulation jack and runs through sliding fit about its right-hand member has the latch board, the torsional spring snap ring is equipped with to the top of latch board, the locking lever right-hand member opposite one side has all been seted up and has been stopped the back draw-in groove, the torsional spring corresponds to rotate the gomphosis and advance in the back draw-in groove and fix with the locking lever block, sets up annular groove and the locating shaft through the central point position cooperation at first steelframe and carries out preliminary calibration combination, annular array sets up a plurality of first angle modulation jack and second angle modulation jack on this basis respectively, the right side frame is equipped with the cardboard, the right side of the right side, the right side is fixed with the latch board, and can hold the angle through the cooperation of two angle modulation jack and can be held the angle and the complex and can support and the complex angle has been set up the angle and the complex and the angle has the jack and the complex and can support and the complex and the demand is more can be more and the complex and the overall and the needs to the angle and the jack to the needs to the overall and the needs to have.
