[0024] 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.

[0025] Embodiment, this embodiment provides a dome construction frame, such as Figure 1 and Figure 3 As shown, the frame includes a supporting steel beam 1 and a supporting steel beam 2 5, a plurality of limiting cross beams 17 are fixed between the supporting steel beam 1 and the supporting steel beam 2 5, both ends of the supporting steel beam 1 and the supporting steel beam 2 5 are fixed with supporting pallets 13, the bottom ends of the supporting pallets 13 are fixed with longitudinal supporting members, four longitudinal supporting members are used to stably support both ends of the supporting steel beam 1 and the supporting steel beam 2 5, the supporting steel beam 1 and the supporting steel beam 2 5 are both bent upward to form an arch support structure, the supporting steel beam 1 and the supporting steel beam 2 5 are assembled together by the limiting cross beam 17, and are used for temporary support and for personnel to go up and down, without setting up a full-hall frame. Moreover, the longitudinal support members include two columns 14, between which a plurality of transversely distributed cross bars are fixed, forming a climbing structure for stepping on. Construction workers climb up along the cross bars to the end positions of supporting steel beam 1 and supporting steel beam 2 5, and they step on a plurality of limiting cross beams 17 as fulcrums for high-altitude standing.

[0026] like Figure 4 and Figure 5 As shown, it also includes a protective component, which includes a plurality of sliding seats 4 and an anti-falling plate 41. The plurality of slide seats are equally divided into two groups. The two groups of sliding seats 4 are respectively slidably clamped on the supporting steel beam 1 and the supporting steel beam 2 5. The bottom wall of the sliding seats 4 is provided with a sliding opening, and the sliding opening is a C-shaped structure, which can not only meet the requirements of sliding along the supporting steel beam 1 or the supporting steel beam 2 5 to adjust the protective position of the entire protective component, but also prevent the sliding seats 4 from being separated from the supporting steel beam 1 or the supporting steel beam 2 5, causing the protective component to fall from a high altitude and cause a safety accident. A pull rod 44 is fixed between two adjacent sliding seats 4 in the same group, and the two sliding seats 4 in the same group are connected together by the pull rod 44. The anti-falling plate 41 is fixed on the outer wall of the same group of sliding seats 4, and is extended to the side away from the frame. The two anti-falling plates 41 widen the support range on both sides of the frame. The anti-falling plates 41 are supported on both sides of the frame to widen the protection range of the entire frame. The position of the protective component can be adjusted at any time according to the high-altitude standing position of the construction personnel. The overall footprint is small and the adjustability is high.

[0027] At the same time, the construction personnel slide the sliding card seat 4 along the outer wall of the supporting steel beam 1 and the supporting steel beam 2 5 according to their own standing position requirements, and adjust the protective position of the entire protective component, so that the construction personnel can use it as a protective component at its side position during construction. Of course, since the supporting steel beam 1 and the supporting steel beam 2 5 are both bent upward, the sliding card seat 4 may slide due to its position in the bent part, causing the protective component to be misaligned with the construction personnel's position and unable to play a protective effect. Therefore, an inverted door frame 42 is fixed between the two groups of sliding card seats 4, and a limit card seat 45 is rotatably provided on the side wall of one of the inverted door frames 42, and a limit notch is provided on the upper end of the limit card seat 45 that can be stuck on the upper limit beam 17 at the corresponding position. The construction worker stands on a limiting beam 17 located on the side of the protective component, bends down and rotates the limiting clamp 45 to flip the limiting notch of the limiting clamp 45 from the upward state to the horizontal state. At this time, the height of the limiting clamp 45 is lower than the height of the limiting beam 17, so that the limiting notch is separated from the limiting beam 17. At this time, the sliding clamp 4 can be pushed to slide along the supporting steel beam 1 and the supporting steel beam 2 5 to the required position, and then the limiting clamp 45 is rotated in the opposite direction to flip the limiting notch from the horizontal state to the upward state. At the same time, the limiting notch can be stuck on the outer wall of the limiting beam 17 to realize the limiting of the protective component.

[0028] Moreover, two inverted door frames 42 are provided, and a supporting base plate 43 located below the limiting beam 17 is fixed between the two inverted door frames 42. When the limiting notch of the limiting clamping seat 45 can be stuck on the outer wall of the limiting beam 17, the construction workers can stand on the supporting base plate 43 to improve the standing stability.

[0029] In this embodiment, multiple supporting steel beams 1 and 2 are provided, and the multiple supporting steel beams 1 are located in the same vertical plane, and the multiple supporting steel beams 2 are located in the same vertical plane. A connecting column 11 is fixed between two adjacent supporting steel beams 1 and between two adjacent supporting steel beams 2 5, and a limiting cross beam 17 is fixed between the supporting steel beam 1 and the supporting steel beam 2 5 located at the lowest side, so as to enhance the supporting strength of the supporting steel beams 1 and 2 5 assembled together and improve the safety performance.

[0030] Preferably, there are two supporting steel beams 1 and two supporting steel beams 5, a reinforcing tube 12 is connected between two adjacent connecting columns 11, multiple reinforcing tubes 12 are distributed in an M-shaped structure, and a main beam 16 is fixed between two supporting plates 13 at the same end, and the supporting strength of the supporting steel beam 1 and the supporting steel beam 2 5 assembled together is further enhanced by the reinforcing tube 12 and the main beam 16.

[0031] like Figure 3 As shown, the present embodiment also includes a sliding seat 15 for adjusting the position by circular rotation, two longitudinal support members located at the same end are fixed to the upper end of the sliding seat 15, and a sliding track 2 of an annular structure is provided below the sliding seat 15. Specifically, a sliding frame 31 is embedded in the bottom end of the sliding seat 15, and both ends of the sliding frame 31 are bent downward to form a back plate, and multiple rollers 32 are provided on the opposite side walls of the two back plates for rotation, and the rollers 32 on the two back plates are rolled and stuck on the two side edges of the upper end of the sliding track 2, and a driving motor 3 is fixed on the outer wall of the sliding seat 15, and the output end of the driving motor 3 passes through the sliding seat 15 and the back plate and is fixedly connected to a corresponding roller 32, and the driving motor 3 can provide rotation power for the corresponding roller 32, and the remaining rollers 32 on the sliding frame 31 rotate synchronously with the rotating roller 32, so as to provide power for the entire sliding seat 15 to adjust the position along the sliding track 2.

[0032] An expansion portion 21 of an annular structure radially extends from the outer wall of the bottom end of the sliding track 2. By adding the expansion portion 21, the supporting stability of the sliding track 2 is enhanced.
