Description

Technical Field

[0001] The invention relates to the technical field of special-shaped roof construction, in particular to a scaffolding fixing device for special-shaped roof construction. Background Art

[0002] With the continuous development and progress of construction technology, people have higher and higher requirements for the appearance of buildings. People are no longer satisfied with the flat design of the roof shape of duplex houses, but choose more fashionable special-shaped roof architectural styles. For example, the triangular design of the roof of a duplex house is more widely used in duplex buildings.

[0003] During the construction of special-shaped roofs, workers must use scaffolding and safety ropes. The existing scaffolding is generally built in a door shape, and the door-shaped scaffolding cannot fit the shape of the special-shaped roof well during the construction of the special-shaped roof. When constructing some roofs that are far away from the scaffolding, they can only use the protection of the safety rope and need to lean over before they can carry out construction and maintenance. The risk factor is relatively high and there are safety hazards. It also brings great inconvenience to the workers. Summary of the Invention

[0016] Beneficial effects

[0017] A special-shaped roof construction hand-scaffold fixing device manufactured by the technical solution of the present invention has the following advantages:

[0018] 1. This device uses support tubes and support rods to build a support frame that fits the special-shaped roof (i.e., triangular roof), so that the scaffolding can be fixed and installed on the special-shaped roof. The workers do not need to extend their bodies significantly out of the scaffolding, which greatly improves the safety of the workers and also provides better and more convenient conditions for the workers' construction.

[0019] 2. This device increases the connection stability between the support tube and the support rod by meshing the teeth one and two at the connection point between the two, providing a stable structural foundation for the fixed installation of the scaffolding and further enhancing the safety of the workers;

[0020] 3. When the long bolt passes through the threaded hole 1 and the threaded hole 2 and extends into the inner cavity of the support tube, the device can realize the fixed connection between the cannula and the support tube, and at the same time, it can also achieve the dual effect of driving the slide rod to slide in the support tube to cause the second tooth to engage with the first tooth, making the assembly and disassembly of the entire device more convenient and quick, and improving the work efficiency of the staff.

[0029] The third innovation of the present application is that a plurality of teeth 17 are provided on the outer circle of the connecting ring, and the teeth are arranged at equal angles on the outer circle of the connecting ring. A sliding rod 18 is provided in the support tube, and the shape and size of the sliding rod match the shape and size of the inner cavity of the support tube and ensure that the outer surface of the sliding rod forms an interference fit with the inner surface of the support tube. One end of the sliding rod is against the closed surface of one end of the support tube, and the other end of the sliding rod is aligned with the opening of the other end of the support tube.
