Description

Technical Field

[0001] The utility model relates to the field of building construction, in particular to a fixing device for the bottom end of a steel pipe of a cantilever scaffold. Background Art

[0002] Nowadays, with the development of urban construction, cantilever scaffolds are often used for the edge protection of high-rise buildings, and a large number of I-beams are generally used in cantilever scaffolds. In order to fix the steel pipes of the cantilever scaffold, positioning steel bars are often welded on the I-beams, but this will increase the on-site welding workload, pollute the environment, and at the same time, the welding quality cannot be guaranteed. In addition, the spacing of the welded steel bars is generally fixed and cannot be adjusted according to the erection requirements of the on-site cantilever scaffold. For example, the spacing between the vertical poles of the on-site erected cantilever scaffold may be 700mm, 800mm, 900mm, 1000mm, etc. In this case, it is necessary to repeatedly weld the positioning steel bars, wasting a lot of manpower and material resources. At the same time, repeated welding on the cantilever scaffold will also damage the strength of the I-beam, bringing great potential safety hazards.

[0003] Therefore, there is an urgent need for a fixing device for the bottom end of a steel pipe of a cantilever scaffold, so as to improve the erection safety of the cantilever scaffold, reduce environmental pollution, shorten the construction period, and reduce the construction cost.

[0016] The following is a further detailed description of the present utility model in conjunction with the attached Figures 1-3 drawings.

[0017] An embodiment of the present utility model discloses a fixing device for the bottom end of a steel pipe of a cantilever scaffold.

[0018] Referring to Figure 1 , Figure 2 , Figure 3 , a fixing device for the bottom end of a steel pipe of a cantilever scaffold includes a connecting pipe, an upper connecting plate 8, a lower connecting plate 9 and a connecting member.

[0020] The upper connecting plate 8 has a convex portion, which is adapted to the top plate of the I-beam 6. The longitudinal section of the upper connecting plate 8 is approximately in the shape of a capital "J", so that the convex portion of the upper connecting plate 8 completely fits on the top of the top plate of the I-beam 6, making the connection more stable.

[0021] An upper gasket 5 is arranged on the upper connecting plate 8. The bolt 3 passes through the upper gasket 5 and is inserted into the upper connecting plate 8.
