Description

Building steel structure connecting piece Technical Field The utility model belongs to the technical field of steel structures, and particularly relates to a building steel structure connecting piece. Background When the construction engineering needs to span a large distance, the length requirement cannot be met by a single I-steel, and the I-steel needs to be lengthened through butt joint to form a continuous beam structure. In the prior art, chinese patent document with the authorized bulletin number of CN213204479U discloses a building steel structure connecting piece, after preliminary butt joint of two ends of I-steel or other connecting parts is carried out, the clamping piece is combined inwards, after the clamping piece passes through the connecting hole, a screw rod is inserted into the inner side surface of the clamping piece, the clamping piece is supported, the concave groove body part is clamped on the inner wall of the connecting hole, a flange column is rotated, threads are screwed on the inner surface of a spiral ring, further, a temporary fixing piece is quickly assembled and temporarily fixed, the two I-steel is connected through a connecting plate, in order to ensure the connecting strength, the ends of the two I-steel are abutted, the length of the butted steel beam is fixed, the small adjustment cannot be carried out according to the assembly requirement in the construction process, the length precision requirement of cutting of the single I-steel is high, and the I-steel can generate a thermal expansion phenomenon when the temperature changes, so that the I-steel is possibly bent or distorted, and the deformation is more obvious in a long-span structure. Therefore, it is necessary to design a building steel structure connecting piece which can slightly adjust the length of the spliced I-steel, reduce the length precision requirement for cutting the I-steel, and avoid bending of the I-steel due to expansion with heat and contraction with cold so as to solve the technical problems faced at present. Disclosure of utility model Aiming at the defects in the prior art, the utility model provides the building steel structure connecting piece which can be used for slightly adjusting the length of the spliced I-steel, reducing the length precision requirement on cutting the I-steel and avoiding bending of the I-steel due to expansion caused by heat and contraction caused by cold. The technical scheme includes that the building steel structure connecting piece comprises a first section bar, a second section bar and a connecting piece, slots matched with the first section bar and the second section bar are formed in the connecting piece in a penetrating mode, waist-shaped holes are uniformly formed in end webs, close to the connecting piece, of the first section bar and the second section bar, the long axis direction of the waist-shaped holes is matched with the extending direction of the slots, round holes matched with the waist-shaped holes are formed in the connecting piece, bolt and nut mechanisms are assembled in the round holes and the corresponding waist-shaped holes, a notch is formed in one end web, close to the connecting piece, of the first section bar, a sliding plate is arranged in one end web, close to the connecting piece, of the second section bar, and the sliding plate is arranged in the notch in a sliding mode. Further, the first section bar and the second section bar are I-steel with the same specification, the connecting piece is of an H-shaped structure matched with the first section bar and the second section bar, and side rib plates which are integrated with the connecting piece are arranged on two sides of the end part of the connecting piece. Further, the side rib plates are flush with the two sides of the connecting piece, the two sides of the connecting piece are detachably and fixedly provided with the partition plates, and the partition plates are in sealing connection with the side rib plates and the connecting piece.
