Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to an H-shaped steel beam and a connecting plate straight hanging structure. Background Art

[0002] With the acceleration of urbanization, high-rise buildings and large infrastructure projects are increasing. Steel structure has become one of the preferred building materials due to its unique advantages. Steel structure is a structure made of steel materials, mainly composed of beams, steel columns, steel trusses and other components made of steel and steel plates. The components or parts are usually connected by welds, bolts or rivets. Because of its light weight and simple construction, it is widely used in large factories, stadiums, super high-rise buildings and other fields; in steel structure construction, H-shaped steel beams are the main components of steel components, with a large number and a large proportion.

[0003] However, the installation process of traditional H-beams and connecting plates is cumbersome and usually requires two hoisting operations: first hoisting the H-beams, then hoisting the connecting plates, and then installing the connecting plates at high altitude. This not only consumes a lot of time and human resources, but also increases the risk of operations, affecting the overall construction progress and cost control. In addition, the high-altitude working environment is complex and changeable, posing a challenge to the safety of operators.

[0004] For example, the utility model patent with the authorization announcement number CN 214935294 U discloses an H-beam lifting assembly for steel structure construction, including a steel wire rope and a clamping assembly that cooperates with the rope. The clamping assembly includes two mounting plates, one end of which extends obliquely to form a hook mounting portion, and the mounting plate has a plurality of parallel hook channels on the side away from the hook mounting portion to facilitate the adjustment of the spacing between the fixed hook and the adjustable hook. The device can slide with the H-beam to make the lifting of the H-beam more convenient, but it still needs to install the connecting plate during high-altitude operations, which reduces construction efficiency and poses safety hazards. Utility Model Content

[0005] In order to solve the above problems, the utility model provides an H-shaped steel beam and connecting plate straight lifting structure. After pre-assembly on the ground, the H-shaped steel beam and the connecting plate are lifted to a predetermined position, which reduces the burden of high-altitude operations and improves the overall construction efficiency.

[0006] The technical solution of the utility model to solve the above problems is as follows:

[0007] An H-shaped steel beam and connecting plate straight hanging structure comprises an H-shaped steel beam and a connecting plate, wherein the H-shaped steel beam comprises a web and flange plates arranged on both sides of the web, and the connecting plate is connected to the flange plates through a connecting piece.

[0008] Preferably, the connecting plate is provided with a plurality of mounting holes, the flange plate comprises an upper flange plate arranged above the web plate and a lower flange plate arranged below the web plate, and the connecting member passes through the mounting holes to overlap and assemble the connecting plate and the upper flange plate.

[0009] Preferably, the number of the connecting members is not less than two.

[0010] Preferably, the connecting member is a bolt and a nut matching the bolt, and the upper end of the nut abuts against the lower surface of the upper flange plate.

[0011] Preferably, the H-shaped steel beam is provided with a lifting lug for providing a connection point for the H-shaped steel beam.

[0012] Preferably, the lifting lug is fixedly disposed above the upper flange plate.

[0013] Preferably, a safety rope is provided between the connecting plate and the lifting lug to prevent the connecting plate from detaching.

[0014] Preferably, the lifting ear is provided with a lifting ear hole, and the safety rope passes through the lifting ear hole and the mounting hole of the connecting plate to connect the lifting ear and the connecting plate.

[0015] The utility model has the following beneficial effects:

[0016] The utility model pre-assembles the H-shaped steel beam and the connecting plate on the ground, and then directly lifts the steel beam and the connecting plate as a whole to a predetermined position through a single hoisting operation, thereby shortening the construction period, reducing the burden of high-altitude operations, and improving the overall construction efficiency; and uses a safety rope to connect the connecting plate to the lifting lug on the H-shaped steel beam, so that the connecting plate will not separate from the H-shaped steel beam during the hoisting process, thereby enhancing the safety of the operation and eliminating safety hazards to the greatest extent.
