Description

Technical Field

[0001] The utility model relates to the technical field of steel structure scaffolds, in particular to a steel structure scaffold which is easy to assemble. Background Art

[0002] Steel structure scaffolding is a structure mainly made of steel. It is mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates. The components or parts are usually connected by welds, bolts or rivets. It is one of the main types of building structures because of its light weight and simple construction.

[0003] The connection structure between the beams and columns of the existing steel structure scaffolding mostly adopts two methods: direct welding and bolt connection. Although the welding structure can meet the connection needs between the two to a certain extent, it is inconvenient to perform high-altitude welding operations in actual applications. When corresponding mounting holes are opened on the steel structure beams and columns and assembled and fixed by bolts, it is difficult to align the mounting holes between the steel structure beams and columns due to the shaking during lifting. The overall assembly requires a long time to complete the mounting hole alignment operation, which increases the construction difficulty. Based on this, a steel structure scaffolding that is easy to assemble is provided. Utility Model Content

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figures 1 to 4 In an embodiment of the utility model, a steel structure scaffold that is easy to assemble includes a column 1 and a combined steel beam 2. A splicing plate 3 and a connecting plate 4 are welded and fixed at both ends of the combined steel beam 2. The two combined steel beams 2 are butt-jointed through the splicing plate 3 and fixed with bolts to form a crossbeam. The combined steel beam 2 is attached to the end face of the column 1 through the connecting plate 4 and fixed with bolts. An auxiliary support assembly 6 is provided at a position near the top of the end face of the column 1. The auxiliary support assembly 6 is used to assist the alignment of the mounting holes on the connecting plate 4 with the mounting holes on the column 1.

[0019] The auxiliary support assembly 6 includes a horizontal transverse guide unit and a horizontal longitudinal guide unit; when a transverse displacement occurs during the lifting of the beam, the horizontal transverse guide unit is used to provide transverse adjustment guidance for the beam; the horizontal longitudinal guide unit is used to provide support and guide operations for the longitudinal movement adjustment of the beam.

[0020] The horizontal transverse guide unit includes an inclined frame 601 and a transverse roller 602; a triangular reinforcing rib 5 is welded and fixed to the lower surface of one end of the combined steel beam 2 located at the connecting plate 4; two inclined frames 601 are provided, and the two inclined frames 601 are symmetrically welded and fixed to the end surface of the column 1, and the transverse roller 602 is rotatably connected between the two inclined frames 601, and the upper surface of the transverse roller 602 protrudes from the upper end of the inclined frame 601; when the beam is hoisted, the inclined surface at the bottom of the triangular reinforcing rib 5 and the extrusion pressure of the transverse roller 602 can make the beam move horizontally and transversely, so as to realize the transverse adjustment operation of the beam.

[0021] The horizontal longitudinal guide unit includes a connecting frame 603, a fixed plate 604, and a longitudinal roller 605; the connecting frame 603 is fixed to the top of the inclined frame 601, and two fixed plates 604 are provided, and the two fixed plates 604 are symmetrically fixed in the middle of the two connecting frames 603, and the longitudinal roller 605 is rotatably connected in the middle of the two fixed plates 604, and the upper surface of the longitudinal roller 605 protrudes from the upper surfaces of the connecting frame 603 and the fixed plate 604; when the crossbeam is distributed in the middle of the two columns 1, the lower surface of the combined steel beam 2 is in contact with the upper surface of the longitudinal roller 605, and the longitudinal roller 605 is used to provide support and guiding operations for the horizontal and longitudinal movement of the crossbeam.

[0022] In this embodiment, it is necessary to add that: the scaffold is provided with multiple groups of columns 1 and combined steel beams 2 along the longitudinal direction, and corresponding connecting frames are provided between two longitudinally adjacent columns 1 and two combined steel beams 2, and structures such as scaffolding boards or rainproof cloths can be installed on the connecting frames. This structure is a conventional structure of existing scaffolds, so it will not be described in detail here.

[0023] When assembling the combined steel beam 2 and the column 1, the operation steps are as follows:

[0024] The two combined steel beams 2 are butted together on the ground through the splicing plate 3 to assemble into a crossbeam, and then the crossbeam is assembled and fixed by passing bolts through the mounting holes on the splicing plate 3 and tightening with nuts.

[0025] After the crossbeam is assembled, it can be lifted by a crane and transferred to the middle upper area between the two columns 1, and then the crossbeam is slowly placed downward. During this process, the crossbeam can be set horizontally as much as possible. However, in actual hoisting operations, it is difficult to make the crossbeam accurately located in the center of the two columns 1. At this time, the crane can be controlled to make the triangular reinforcement 5 at one end of the crossbeam close to the transverse roller 602 on the corresponding side (it should be noted that during the crossbeam hoisting operation, construction personnel will climb to the top of the column 1 to assist in adjusting the position of the crossbeam. For example, when the crane slowly lowers the crossbeam, the construction personnel can apply a certain thrust to the crossbeam when they come into contact with the crossbeam, so that the crossbeam can be better aligned with the transverse roller 602). When the lower surface of the triangular reinforcement rib 5 contacts the transverse roller 602, the crossbeam continues to be lowered. At this time, the extrusion of the inclined lower surface of the triangular reinforcement rib 5 and the transverse roller 602 can provide a transverse thrust for the crossbeam, so that this end of the crossbeam is further close to the column, and the construction personnel at the other end can further push the crossbeam longitudinally, so that the other end of the crossbeam is close to the transverse roller 602 on the other column 1, so that the crossbeam can be adjusted to a horizontal and transverse position and distributed in the center between the two columns 1.

[0026] Finally, the connecting plates 4 at both ends of the beam are attached to the end faces of the two columns 1, and the lower surface of the combined steel beam 2 is attached to the upper surface of the longitudinal roller 605. At this time, the horizontal and longitudinal movement of the beam can be adjusted according to the alignment state of the mounting holes on the connecting plate 4 and the column 1. At this time, a certain pulling force is applied to the beam by a crane, and the construction personnel can manually push the beam. The longitudinal roller 605 rotates synchronously to reduce the movement resistance of the beam and provide support for the beam to avoid the shaking caused by the beam being suspended in the air, making the movement of the beam more stable. In this way, the connecting plate 4 can be quickly aligned with the mounting holes on the column 1, and then the connecting plate 4 and the column 1 can be fixed by bolts. The overall operation is simple and convenient.

[0027] Please refer to Figures 1 to 4 When the two connecting plates 4 are respectively fitted with the end faces of the two columns 1, the upper surface of the inclined frame 601 is located below the lower surface of the triangular reinforcement rib 5, and the upper surface of the transverse roller 602 does not contact the lower surfaces of the combined steel beam 2 and the triangular reinforcement rib 5; the end surface of the triangular reinforcement rib 5 is flush with the end surface of the connecting plate 4, and the triangular reinforcement rib 5 is located at the center position of the junction of the combined steel beam 2 and the connecting plate 4.

[0028] In this embodiment: through this structure, the crossbeam can be adjusted in the longitudinal direction without colliding or interfering with the tilting frame 601 and the transverse roller 602; in addition, the triangular reinforcement ribs 5 can provide reinforced support for the movement and positioning of the combined steel beam 2.

[0029] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
