Description

Technical Field

[0001] The invention relates to the technical field of construction engineering, in particular to a drainage gate rack full-length cantilever scaffold. Background Art

[0002] Cantilever scaffolding refers to a scaffolding whose structure unloads on a rigid cantilever beam attached to the building structure. It is used for main construction or decoration engineering operations and their safety protection needs.

[0003] Cantilever scaffolding can be divided into two types: one-cantilever per layer and one-cantilever per multiple layers. For the one-cantilever per layer method, the bottom of the vertical pole is placed on the floor, beam or wall and other building parts. After being tilted outward and fixed, a horizontal pole is set up on the upper part and a scaffolding board is laid to form a construction layer. The construction is completed at one layer height. After entering the upper layer, the scaffolding is re-erected to provide construction for the next layer. For the multi-layer cantilever scaffolding method, the full-height scaffolding is divided into several sections, with each section having a height of no more than 20m. The cantilever beam or cantilever frame is used as the scaffolding foundation to erect the scaffolding in sections. This method can be used to erect scaffolding of more than 50m. The facade of the cantilever scaffolding must be fully equipped with scissor braces.

[0004] During the construction of the tide gate opening and closing machine room, scaffolding is also required, and the scaffolding needs to be erected from the bottom plate of the gate to the upper part. However, it was found during the implementation process that there are at least the following defects in the existing technology: when encountering the flood season, due to the high water level of the river, it will cause the existing scaffolding to be difficult to ensure the stability of its structural foundation. Summary of the invention

[0005] The purpose of the present invention is to provide a full-length cantilever scaffolding for a drainage gate, which solves the technical problem that the stability of the scaffolding structure foundation is difficult to ensure during the flood season during the construction of a tide gate opening and closing machine room.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions:

Rod, longitudinal horizontal rod and diagonal rod, the vertical rod is vertically fixed on the pressure plate, the vertical rod is fixed with the transverse horizontal rod perpendicular to the cantilever beam, the transverse horizontal rod is fixed with a plurality of longitudinal horizontal rods, the longitudinal horizontal rod is parallel to the cantilever beam, U-shaped upper pull pieces are respectively provided near the two ends of the cantilever beam, one end of the diagonal rod is fixed to the cantilever beam through the U-shaped upper pull piece, and the other end is diagonally connected to the superstructure structure, the diagonal rod includes a tubular flower basket, the two axial ends of the flower basket have internal threads, the internal threads at the two ends of the flower basket are respectively connected with a positive wire pull rod and a negative wire pull rod, and the tension of the diagonal rod can be adjusted by rotating the flower basket.

[0008] Since the cantilever beam is located above the bridge deck and scaffolding is fixed at both ends of the cantilever beam, the cantilever beam can be stressed more evenly. When encountering flood season, the scaffolding can be guaranteed to have a strong structural foundation and stability.

[0009] Furthermore, the cantilever beam is installed on the bridge deck through U-shaped bolts, the bottom of the U-shaped bolts is embedded in the bridge deck, the opening of the U-shaped bolts faces upward and the cantilever beam is located in the opening of the U-shaped bolts, and a cover plate is installed at the opening of the U-shaped bolts through bolts, and the cover plate can press the cantilever beam to facilitate the fixation of the cantilever beam.

[0010] Furthermore, a pad is provided at the clamping and fixing position of the cantilever beam and the U-shaped bolt, and two sides of the pad are respectively fitted with the U-shaped bolt and the cantilever beam.

[0011] Furthermore, structural reinforcement ribs are symmetrically embedded in the bridge deck, and the structural reinforcement ribs penetrate the bottom contour of the U-shaped bolt and contact the bottom of the U-shaped bolt, which can make the U-shaped bolt more reliably fixed, thereby improving the stability of the overall structure.

[0012] Furthermore, a thread protection sleeve capable of protecting the thread is embedded in the exposed thread threads of the positive thread pull rod and the reverse thread pull rod connected to the flower basket.

[0013] Furthermore, the thread protection sleeve is made of rubber.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] The technical solution provided by the embodiments of the present invention is described in detail below with reference to the accompanying drawings.

[0028] like Figures 1 to 3 As shown, the full-length cantilever scaffolding of the drainage gate frame of this embodiment includes a cantilever beam 1, the end of the cantilever beam 1 extends to the outside of the bridge body and is fixed with a scaffolding, the scaffolding includes a vertical pole 2, a transverse horizontal rod 4 perpendicular to the cantilever beam 1 is fixed on the vertical pole 2, a plurality of longitudinal horizontal rods are fixed on the transverse horizontal rod 4, and the longitudinal horizontal rods are parallel to the cantilever beam 1, the cantilever beam 1 is located above the bridge deck 5, and the two ends of the cantilever beam 1 extend to the two sides of the bridge body respectively, and the two ends of the cantilever beam 1 are fixed with scaffolding.

[0029] Among them, since the cantilever beam 1 is located above the bridge deck 5 and the cantilever beam 1 adopts a conventional design, scaffolding is fixed at both ends of the cantilever beam 1, so that the cantilever beam 1 can be more evenly stressed. When encountering the flood season, the scaffolding can be guaranteed to have a strong structural foundation and stability.

[0030] Specifically, the cantilever beam 1 is an I-beam, located above the bridge deck 5, and fixed by a U-bolt 6. The profile of the U-bolt 6 is "U", the bottom of the U-bolt 6 is pre-buried in the bridge deck 5, the opening of the U-bolt 6 faces upward, and a cover plate 7 is installed at the opening of the U-bolt by bolts. The cantilever beam 1 is located in the U-shaped profile of the U-bolt 6 and is pressed by the cover plate 7. Such an arrangement can facilitate the fixing and disassembly of the cantilever beam 1.

[0031] Preferably, a pad 8 is provided at the fixing place of the cantilever beam 1 and the U-bolt 6. The pad 8 is located at the position where the U-bolt 6 and the cantilever beam 1 are clamped, and the two sides of the pad 8 are respectively fitted with the U-bolt 6 and the cantilever beam 1, thereby making the cantilever beam 1 and the U-bolt 6 more reliably fixed. In addition, structural reinforcement ribs are also pre-embedded in the bridge deck 5, and the structural reinforcement ribs penetrate the bottom profile of the U-bolt 6 and contact the bottom of the U-bolt 6, so that the U-bolt 6 is fixed on the bridge deck 5 more reliably.

[0032] In addition, movable positioning piles are installed at both ends of the cantilever beam 1. The movable positioning piles include a U-shaped plate 9 and a pressure plate 10. The U-shaped plate 9 has outer edges on both sides. The outer edges on both sides of the U-shaped plate 9 are fixed to the pressure plate 10 by bolts, and the vertical pole 2 is vertically fixed on the pressure plate 10. The pressure plate 10 is located above the U-shaped plate 9. The pressure plate 10 has a convex portion 11 facing downward. The convex portion 11 of the pressure plate 10 can cooperate with the opening at the upper end of the U-shaped plate 9 and can contact the cantilever beam 1. When the U-shaped plate 9 and the pressure plate 10 are fastened by bolts, the convex portion 11 of the pressure plate 10 can press the cantilever beam 1, so that the movable positioning pile can be fixed on the cantilever beam 1 more reliably, thereby ensuring that the stability of the vertical pole 2 is stronger.

[0033] In this embodiment, if Figure 4 , Figure 5 As shown, the scaffolding also includes a diagonal tie rod 12. Correspondingly, U-shaped upper pull members 13 are respectively provided on the cantilever beam 1 near its two ends. One end of the diagonal tie rod 12 is fixed to the cantilever beam 1 through the U-shaped upper pull member 13, and the other end of the diagonal tie rod 12 is diagonally connected to the superstructure structure, which can further ensure the stability of the cantilever beam 1 and the scaffolding.

[0034] The inclined tie rod 12 includes a tubular flower basket 14, a positive thread tie rod 15 and a negative thread tie rod 16. The two axial ends of the flower basket 14 have internal threads. The positive thread tie rod 15 and the negative thread tie rod 16 are respectively connected to the two axial ends of the flower basket 14. At this time, the tension of the inclined tie rod 12 can be adjusted by rotating the flower basket 14. In addition, a thread protection sleeve 17 made of rubber material is embedded in the thread exposed by the connection between the positive thread tie rod 15, the negative thread tie rod 16 and the flower basket 14, and the thread protection sleeve 17 can protect the thread.

[0035] The drainage gate frame full-length cantilever scaffolding of the present invention can make the cantilever beam bear the force more evenly because the cantilever beam is located above the bridge deck and scaffolds are fixed at both ends of the cantilever beam. When encountering the flood season, it can ensure that the scaffolding has a strong structural foundation and stability; at the same time, it avoids the factor of being unable to determine the stability of the scaffolding foundation due to the flooded part, and meets the needs of construction and structural maintenance.

[0036] The embodiments described above are only descriptions of the preferred modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
