Technical Field
The utility model belongs to the technical field of the building, specifically be movable roof beam atress indulges muscle joint device.
Background
Super high-rise building has been applied to the construction engineering field gradually today, building height is more and more high, building dead weight is bigger and bigger, the load that every post was born in the building is also bigger and bigger, the section that adopts reinforced concrete post is also bigger and bigger, influence the availability factor of architectural area, adopt shaped steel concrete post can effectively reduce the post section, improve the availability factor of architectural area, nevertheless because reinforced concrete roof beam atress is indulged the muscle and can't all pass from the post, there is the problem that the shaped steel in partial roof beam atress is indulged the muscle and is connected with shaped steel in the shaped steel concrete post.
The beam stressed longitudinal rib is connected with the section steel in the section steel concrete column by welding and fixing a steel sleeve on the section steel, and the beam stressed longitudinal rib is provided with straight threads and is connected with the straight threads. When the beam stressed longitudinal rib is connected with the steel sleeve welded and fixed on the section steel, the beam stressed longitudinal rib needs to be rotated, and the threads on the beam stressed longitudinal rib are rotated into the steel sleeve welded and fixed on the section steel. Some building beams are bent when stressed longitudinal bars are bent, are complex in structure and cannot rotate during connection, and cannot be connected with a steel sleeve welded and fixed on the section steel.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a muscle joint device is indulged to movable roof beam atress through rotating short connecting reinforcement and movable steel sleeve, can link together the unable pivoted roof beam atress that the shape is complicated on muscle and the shaped steel welded fastening steel sleeve.
The specific technical scheme is as follows:
the movable beam stressed longitudinal bar joint device comprises a movable steel sleeve, short connecting steel bars and a fixed sleeve, wherein straight steel bar threads are arranged at two ends of each short connecting steel bar; the inner wall of one end of the movable steel sleeve is provided with internal threads which are connected with straight threads of the steel bars at one end of the short connecting steel bars, and the inner wall of the other end of the movable steel sleeve is provided with an inner screw thread which is used for being connected with the stressed longitudinal bars of the beam; the other end of the short connecting steel bar is connected with a fixing sleeve, and the fixing sleeve is welded on the column inner section steel.
The middle part of the outer wall of the movable steel sleeve is provided with a groove.
The utility model provides a muscle piecing devices is indulged to movable roof beam atress, it is supporting with roof beam atress reinforcing bar, processing in mill accomplishes the back, the straight screw thread reinforcing bar connection piecing devices of short joint bar in movable area that the every steel column of production corresponds, fixed sleeve is on mill's accuracy welds the shaped steel post, piecing devices together send to the job site with the shaped steel post, has also reduced the secondary operation at scene, raises the efficiency, guarantees going on smoothly of engineering.
