DETAILED DESCRIPTION

[0019] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0020] like Figure 1-Figure 3 The disc-type scaffolding with adjustable rods shown in the figure comprises vertical poles 9, disc-fastening members 10 and adjustable rods 11; the adjustable rods 11 comprise adjustable cross bars and adjustable diagonal rods; a plurality of adjustable cross bars are connected at intervals along the height direction between two vertical poles 9 adjacent in the horizontal direction, and the two ends of the adjustable cross bars are respectively connected to two adjacent vertical poles 9 through the disc-fastening members 10; an adjustable diagonal rod is connected diagonally between two adjustable cross bars adjacent in the height direction through the disc-fastening members 10.

[0021] The adjustable cross bar includes a first cross bar group, a second cross bar group and a third cross bar group with adjustable lengths; the length range of the first cross bar group is 600mm to 900mm, the length range of the second cross bar group is 900mm to 1200mm, and the length range of the third cross bar group is 1200mm to 1500mm.

[0022] The adjustable diagonal rod comprises a first diagonal rod assembly, a second diagonal rod group and a third diagonal rod group, the lengths of which are adjustable.

[0023] For the sake of convenience of description, the first cross bar group is also called cross bar group 1, the second cross bar group is called cross bar group 2, the third cross bar group is called cross bar group 3, the first diagonal bar group is called diagonal bar group 1, the second diagonal bar group is called diagonal bar group 2, and the third diagonal bar group is called diagonal bar group 3.

[0024] like Figure 1 As shown, the applicable range of cross bar group 1 is 600mm~900mm, the applicable range of cross bar group 2 is 900mm~1200mm, and the applicable range of cross bar group 3 is 1200mm~1500mm. The specifications of the diagonal bar group are determined according to the step distance, including diagonal bar groups with three step distance specifications of 1000mm, 1500mm and 2000mm. Each diagonal bar group can be used in scenes with a horizontal distance of 600mm~1500mm.

[0025] Now, take a construction project that uses a disc-type full-frame as a support frame as an example. The building has a complex shape, inconsistent frame column spacing, most frame beams are not vertically crossed, and there are many secondary beams. For a disc-type full-frame with a standard modulus, the layout conditions are relatively complicated. It is necessary to use ordinary steel pipes and the disc-type frame to connect with fasteners for adjustment in areas around the columns and beam edges that do not meet the standard modulus. This treatment method is subject to modulus restrictions and is difficult to reflect the advantages of the disc-type frame. In addition, due to the mixed use of rods, it is difficult to ensure the accuracy of safety calculations during design. When using adjustable rods 11, the frame layout can be optimized, and the mixed use of steel pipe fastener frames and disc-type frames can be completely avoided, making the frame more stable, better stressed, and the efficiency of erection and dismantling is also improved.

[0026] Specific application cases such as Figure 4 As shown, Figure 4 This is an example of a conventional disc-type scaffolding without using adjustable rods 11. Due to the dense and messy structure of the beams and slabs, the disc-type scaffolding with a fixed module cannot be evenly arranged horizontally and vertically at the beam-column and beam-slab nodes, and a large number of steel pipe fasteners are required for connection and adjustment, resulting in a messy on-site rods, which is not conducive to erection and dismantling. Figure 5 As shown, after using the disc-type scaffolding with telescopic adjustable rods 11, the rods can be adjusted at various complex node positions, and the overall layout is horizontal and vertical, which is beneficial to construction and also improves the force-bearing performance of the rods.

[0027] In the utility model, the adjustable rod 11 is divided into an adjustable horizontal rod and an adjustable diagonal rod. When considering the arrangement of the frame, the adjustable rods 11 of different specifications are selected for adjustment according to the actual situation.

[0028] Among them, the adjustable cross bar includes a cross bar buckle joint 3, a cross bar with thickened wall 2, a cross bar threaded sleeve 4 and a cross bar screw 1; one end of the cross bar threaded sleeve 4 is threadedly matched with one end of the cross bar screw 1, and the other end is respectively provided with a cross bar with thickened wall 2 and a cross bar buckle joint 3.

[0029] For the three specifications of the adjustable cross bar, a combination of a cross bar screw 1 of the same length and a cross bar threaded sleeve 4 connected to a wall-thickened cross bar 2 of different lengths is actually used. In other words, the lengths of the cross bar screw 1 and the cross bar threaded sleeve 4 of the three specifications of the adjustable cross bar are the same. The difference is that the lengths of the wall-thickened cross bar 2 connected to the cross bar threaded sleeve 4 are different, resulting in different lengths of the final adjustable cross bar.

[0030] For example, the crossbar set 1 is a combination of a crossbar screw 1 with a fixed length of 350 mm and a crossbar threaded sleeve 4 with a length of 350 mm. In this combination, the length of the thickened crossbar 2 connected to the crossbar threaded sleeve 4 is 50 mm, and the adjustment range of the crossbar set 1 is 600 mm to 900 mm.

[0031] The crossbar set 2 is a combination of a crossbar screw 1 with a fixed length of 350 mm and a crossbar threaded sleeve 4 with a length of 350 mm. The length of the thickened crossbar 2 connected to the crossbar threaded sleeve 4 in the combination is 350 mm. The adjustment range of the crossbar set 1 is 900 mm to 1200 mm.

[0032] The crossbar group 3 is a combination of a crossbar screw 1 with a fixed length of 350mm and a crossbar threaded sleeve 4 with a length of 350mm. In this combination, the length of the thickened wall crossbar 2 connected to the crossbar threaded sleeve 4 is 650mm, and the adjustment range of the crossbar group 1 is 1200mm to 1500mm.

[0033] The three types of rod groups can achieve an adjustment range of 600mm to 1500mm, which can meet the non-standard module scenarios encountered in actual engineering.

[0034] The adjustable bevel rod includes a bevel rod buckle joint 7, a bevel rod with thickened wall 6, a bevel rod threaded sleeve 8 and a bevel rod screw 5; one end of the bevel rod threaded sleeve 8 is threadedly matched with one end of the bevel rod screw 5, and the other end is respectively provided with a bevel rod with thickened wall 6 and a bevel rod buckle joint 7.

[0035] For the adjustable bevel rod, for the three specifications of the adjustable bevel rod, a combination of a bevel rod screw 5 of the same length and a bevel rod threaded sleeve 8 connected with bevel rods 6 of different lengths with thickened walls is actually adopted.

[0036] The bevel rod group 1 is a combination of a bevel rod screw 5 with a fixed length of 627 mm and a bevel rod threaded sleeve 8 with a length of 627 mm. The total length of the thickened-wall bevel rod 6 and the bevel rod buckle joint 7 at its end in this combination is 232 mm. The bevel rod group 1 is suitable for scenes with a step distance of 1000 mm and a horizontal distance of 600 mm to 1500 mm.

[0037] The bevel rod group 2 is a combination of a bevel rod screw 5 with a fixed length of 627mm and a bevel rod threaded sleeve 8 with a length of 496mm. The total length of the thickened-wall bevel rod 6 and the bevel rod buckle joint 7 at its end in this combination is 704mm. The bevel rod group 2 is suitable for scenarios with a step distance of 1500mm and a horizontal distance of 600mm to 1500mm.

[0038] The diagonal rod group 3 is a combination of a fixed length of 627mm diagonal rod screw 5 and a length of 408mm diagonal rod threaded sleeve 8. The total length of the thickened diagonal rod 6 and the diagonal rod buckle joint 7 at the end of the combination is 1188mm, which is suitable for scenes with a step distance of 2000mm and a horizontal distance of 600mm to 1500mm. According to the step distance, the diagonal rod group of corresponding specifications is selected, and combined with the horizontal rod group, the module adjustment of the disc buckle frame can be realized.

[0039] In order to ensure that the crossbar screw 1 is screwed into the crossbar threaded sleeve 4 to a minimum depth of 50mm, the crossbar screw 1 is designed to be 350mm long, and the length of the diagonal rod screw 5 is also reserved for a minimum screw-in depth of 50mm according to the adjustment range. For this reason, this safety length is marked on the fixed-specification screw rod (crossbar screw 1 or diagonal rod screw 5). When the maximum adjustment length is reached, it should be ensured that this mark is screwed into the corresponding sleeve rod (crossbar threaded sleeve 4 or diagonal rod threaded sleeve 8). If it cannot be guaranteed, consider replacing the rod group according to the actual situation to meet the erection needs, thereby ensuring the stability of the connection.

[0040] For the design of the adjustable rod 11, due to the existence of the matching section between the screw and the sleeve, the internal wall thickness of the rod varies. Therefore, during processing, it is necessary to consider using a steel pipe with a thicker wall thickness to ensure that the wall thickness of the steel pipe at the thinnest part of the matching section meets the wall thickness required by the specification. At the same time, it is appropriate to use higher strength steel during processing.

[0041] When setting up a disc-type scaffold in an actual project and encountering a non-standard modulus scenario, the adjustable rod 11 described in the utility model can be used for setting up. The adjustable rod 11 of the utility model is simple to make and easy to set up. It is only necessary to design the standard span frame layout first, and select rods with an appropriate adjustment range for arrangement according to the rod length required for the non-standard section. The adjustable rod 11 is used in the form of a rod group, which is produced by the manufacturer and purchased in a unified manner. The required specifications of the horizontal rod group and the diagonal rod group can be selected and used in combination according to the design and production requirements. The rod group described in the present invention is suitable for most scenarios in actual engineering.

[0042] The above are only preferred implementations of the utility model. The protection scope of the utility model is not limited to the above embodiments. All technical solutions under the idea of ​​the utility model belong to the protection scope of the utility model. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the utility model should also be regarded as the protection scope of the utility model.
