Description

Technical Field

[0001] The utility model belongs to the technical field of steel structure installation, in particular to a connection structure capable of quickly installing steel beams. Background Art

[0002] Steel structure is a structure made of steel materials and is one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel and steel plates. Because of its light weight and simple construction, it is widely used in large factories, venues, super high-rise buildings, bridges and other fields. In particular, in industrial buildings and civil buildings involving structures with floors, most of them use "H"-shaped steel beams as the support of the floor slabs, and the number is particularly large. In the process of connecting and installing "H"-shaped steel beams to each other (such as the connection between the vertical support steel beam and the horizontal support steel beam), most of them use the hoisting method to lift the horizontal support steel beam and align its end with the connection on the vertical support steel beam. Then, multiple bolts are screwed into the corresponding screw holes one by one to connect and fix the vertical support steel beam and the horizontal support steel beam. Because the horizontal support steel beam is prone to shaking during the hoisting process, the lack of corresponding limiting mechanism at the joint makes it easy to cause the joint of the steel beam to be more troublesome, which is not convenient for the rapid installation and fixation of the steel beam, affecting the installation efficiency of the steel beam.

[0029] Example:

[0030] During the installation of the steel beam, the steel plate 3 is first welded to the side of the vertical steel beam 1, and then the transverse steel beam 2 is hoisted by hoisting. At the same time, the waist plate at one end of the transverse steel beam 2 is adjusted to fit into the avoidance groove between the two limit plates 20, so that the wing plate on the upper side of the transverse steel beam 2 abuts against the top of the limit plate 20. At this time, the bottom of the transverse steel beam 2 contacts the support plate 5. Under the action of the fixing rod 4, the bottom of the transverse steel beam 2 is supported and the transverse steel beam 2 is pushed toward the direction close to the vertical steel beam 1 until the end of the transverse steel beam 2 abuts against the steel plate 3.

[0031] Secondly, under the hinged action of the movable rod 6 and the steel plate 3, the movable rod 6 is adjusted to flip toward the direction close to the transverse steel beam 2 until the pressure plate 7 presses on the top of the transverse steel beam 2;

[0032] Then, the knobs 19 on the upper and lower sides are turned, and the corresponding active bevel gear 16 is driven to rotate under the action of the rotating rod 17. Under the meshing action of the active bevel gear 16 and the driven bevel gear 15, the screw rod 9 is driven to rotate synchronously under the rotation cooperation of the support shaft 14, the support plate 5 and the pressure plate 7. Under the thread cooperation of the screw rod 9 and the T-shaped block 10, the T-shaped block 10 is driven to move along the direction of the T-shaped groove 8 to the transverse steel beam 2. Under the action of the connecting plate 11, the upper and lower L-cards 12 are driven to move synchronously in the direction of the transverse steel beam 2 until the L-cards 12 and the wing plates of the transverse steel beam 2 are abutted, so as to achieve the purpose of limiting and clamping the wing plates at one end of the transverse steel beam 2, and then achieve the purpose of docking and limiting the end head of the transverse steel beam 2, so as to realize the rapid docking of the vertical steel beam 1 and the transverse steel beam 2, and ensure the stability of the transverse steel beam 2.

[0033] Finally, under the one-to-one correspondence between the positioning screw hole, the first screw hole and the through hole, combined with the one-to-one correspondence between the second screw hole and the locking screw hole, the transverse steel beam 2 is connected and fixed by bolts, so that the transverse steel beam 2 is fixedly connected together with the steel plate 3, thereby realizing the connection and fixation of the vertical steel beam 1 and the transverse steel beam 2, solving the problem that in the process of lifting the transverse steel beam 2 by hoisting in the prior art, there is a lack of corresponding limiting mechanism at the joint, and the transverse steel beam 2 is prone to shaking, which makes the jointing of the steel beam more troublesome, is not convenient for the rapid installation and fixation of the steel beam, and affects the installation efficiency of the steel beam.
