Description

Technical Field

[0001] The utility model relates to the technical field of steel pipe column-beam through-type partition node welding, in particular to a steel pipe column-beam through-type partition node welding structure. Background Art

[0002] In the prefabricated steel structure system, steel tube components and steel plate components are important components connecting the upper structure and the foundation of the steel structure, and are an important factor in determining the bearing capacity of the entire structural system. The fatigue problem of steel tube welding nodes between steel tube components and steel plate components is a long-standing problem at home and abroad. It widely occurs in structures such as building steel tube frames and bridge steel tube trusses that use steel tubes as force-transmitting components, threatening the safety and normal operation of the structure.

[0003] A steel pipe diagonal brace welded node structure subjected to large eccentric fatigue loads disclosed in publication number CN219364967U can reduce the stress concentration and fatigue stress amplitude of the welding details on the tensile side, improve the fatigue strength of the welding details on the compressive side, and generally improve the fatigue life of the steel pipe diagonal brace welded node under large eccentric fatigue loads.

[0004] However, this steel pipe bracing welded node structure subjected to large eccentric fatigue load has the following disadvantages:

[0005] (1) Direct butt joint of steel pipes lacks stability and strength. As the columns and beams are used, vibration will occur at the welds. In addition, the welds lack isolation protection, which leads to oxidation corrosion of the welds and reduces durability.

[0006] (2) The lack of welding pads causes the weld to corrode the inner wall of the steel pipe. At the same time, the lack of limit stops causes the steel pipe to be unable to align and misalign. Utility Model Content

[0007] 1. Technical issues to be solved

[0008] The technical problem solved by the utility model is to provide a steel pipe column-beam through-type partition node welding structure which is highly practical, can be simply operated and has a relatively simple structure. It solves the problems of lack of stability and strength raised in the above-mentioned background technology, and vibration will be generated at the welding point as the columns and beams are used. The welding point lacks isolation protection, which leads to oxidation corrosion of the weld and reduces durability. The lack of welding pads causes the weld to corrode the inner wall of the steel pipe. At the same time, the lack of limiters makes it impossible to align the steel pipes and causes misalignment.

[0009] (II) Technical solution

[0010] To achieve the above objectives, the utility model is implemented through the following technical solutions: a steel pipe column-beam through-type partition node welding structure, including a first steel pipe, a square steel ring is arranged on the top of the first steel pipe, a second steel pipe is sleeved on the top of the square steel ring, and a reinforcement component for reinforcement is sleeved at the connection between the first steel pipe and the second steel pipe.

[0011] Optionally, the reinforcement assembly includes a first square tube sleeved on a connection between the first steel tube and the second steel tube, the bottom of the first square tube is fixedly connected to the second square tube, and the bottom of the second square tube is fixedly connected to a third square tube.

[0012] Optionally, a plurality of threaded holes are provided on both sides of the first square tube and the third square tube, and the threaded holes are distributed in a rectangular array.

[0013] Optionally, two sides of the bottom end of the first square tube are fixedly connected with a first plane plate in an axisymmetric manner, and two sides of the top end of the third square tube are fixedly connected with a second plane plate in an axisymmetric manner.

[0014] Optionally, threaded holes are provided on both sides of the top end of the first steel pipe and on both sides of the bottom end of the second steel pipe, and the threaded holes are distributed in a rectangular array.

[0015] Optionally, a threaded bolt for fixing is arranged inside the threaded hole, and one end of the threaded bolt is threadedly penetrated through the interior of the threaded hole and is connected with the internal thread of the threaded hole.

[0016] Optionally, a first reinforcement plate is disposed inside the top end of the first steel pipe, and a second reinforcement plate is disposed inside the bottom end of the second steel pipe.

[0017] (III) Beneficial effects

[0018] The utility model provides a steel pipe column-beam through-type partition node welding structure, which has the following beneficial effects:

[0019] 1. The steel pipe column-beam through-type partition node welding structure, through the arrangement of the square steel ring, the first reinforcement plate and the second reinforcement plate, can align the first steel pipe and the second steel pipe when welding the steel pipe column-beam node, and sleeve the bottom of the second steel pipe on the surface of the square steel ring, and be limited by the square steel ring, so that the top of the first steel pipe and the bottom of the second steel pipe are aligned. When welding, since the square steel ring is located at the bottom of the weld, it acts as a welding pad to improve the stability of the welding. The presence of the first reinforcement plate and the second reinforcement plate improves the welding strength and stability, prevents internal stress and cracks from being generated at the welding point, and can also play a role in separating and isolating the inside of the two steel pipes, preventing impurities, moisture, etc. from entering the inside of the steel pipe, thereby extending the service life of the steel pipe.

[0020] 2. The steel pipe column-beam through-type partition node welding structure, through the setting of reinforcement components, after welding is completed, the first square tube, the second square tube and the third party tube can be inserted from the top of the second steel tube, and the threaded holes on the sides of the first square tube and the third party tube are aligned with the threaded holes on both sides of the top of the first steel tube and the bottom of the second steel tube. At the same time, the threaded bolts are screwed in to fix them, and the position of the weld is located inside the second square tube, which can further strengthen the connection, reduce vibration and stress at the weld, extend the service life, prevent external substances from invading the weld, reduce the possibility of oxidation and corrosion, and improve the stability and durability of the weld.
