[0032] As Figures 2 - 5 shown, this embodiment provides an extension rack, which includes a vertical rod 1, a bearing plate 2, a working plate 3 and a ladder 4. The vertical rod 1 extends along the vertical direction. There are multiple vertical rods 1, and the multiple vertical rods 1 enclose to form a passage space 11. The bearing plate 2 is arranged on the vertical rod 1 with adjustable height. The working plate 3 can slide vertically within the passage space 11 and is detachably connected to the vertical rod 1. The working plate 3 and the bearing plate 2 are parallel to each other and arranged at intervals. A passable opening 31 that can be opened and closed is provided on the working plate 3. The ladder 4 is arranged on the vertical rod 1.

[0033] In this embodiment, the vertical rod 1 extends along the vertical direction to ensure the stability and load-bearing capacity of the entire extension rack. There are multiple vertical rods 1, and the multiple vertical rods 1 enclose to form a passage space 11 to facilitate the up-and-down passage of operators. The bearing plate 2 is arranged on the vertical rod 1 with adjustable height to facilitate adjusting the height of the bearing plate 2 according to actual working requirements to ensure the load-bearing capacity of the extension rack and the working requirements of the operators. The working plate 3 can slide vertically within the passage space 11 and is detachably connected to the vertical rod 1, thereby providing a flexible working area for the operators and being convenient for assembly, disassembly and later maintenance. The working plate 3 and the bearing plate 2 are parallel to each other and arranged at intervals to ensure the safe passage and operation of the operators. A passable opening 31 that can be opened and closed is provided on the working plate 3 to be opened when the operators need to enter and exit and closed in time after the construction is completed to ensure the safety of the construction area. The ladder 4 is arranged on the vertical rod 1 to facilitate the operators to enter and exit the passage space 11 and perform high-altitude operations. Through the above settings, the extension rack of this embodiment can facilitate the operators to adjust the working height, facilitate construction, and is stable and safe.

[0034] Specifically, as Figure 2 shown, the multiple vertical rods 1 jointly enclose to form a cuboid, that is, the passage space 11 is in the shape of a cuboid. Adjacent two vertical rods 1 are connected by connecting rods to ensure the stability and load-bearing capacity of the entire frame structure.

[0035] Specifically, as Figures 2 - 4As shown in the figure, the extension frame further includes a diagonal brace 5. The diagonal brace 5 is arranged between two adjacent vertical poles 1, making the structure of the extension frame more stable. The two ends of the diagonal brace 5 are respectively detachably connected to the two vertical poles 1, making the erection and disassembly process of the extension frame more convenient and fast. The operator can quickly install or disassemble the diagonal brace 5 according to the actual construction requirements to adapt to different construction environments and height requirements. Among them, the above-mentioned detachable connection can adopt snap connection, threaded connection, etc., and will not be limited too much here.

[0036] More specifically, as Figure 2 shown in the figure, a plurality of vertical poles 1 together form a load-bearing frame 12. At the opposite ends of the load-bearing frame 12, two diagonal braces 5 are arranged at an angle. A stable triangular structure is formed between the two diagonal braces 5 and the vertical poles 1, which can improve the wind resistance, earthquake resistance, etc. of the extension frame, ensure the safety of construction workers, and further enhance the stability of the extension frame, making the extension frame more stable when bearing heavy loads or external forces.

[0037] Specifically, as Figures 2 - 4 shown in the figure, in this embodiment, the extension frame further includes a first fastener. The vertical pole 1 is provided with a plurality of connection holes 13 at intervals along its own extension direction. The bearing plate 2 extends in the horizontal direction and can pass through the vertical pole 1 in the vertical direction, so that the bearing plate 2 can slide on the vertical pole 1 in the vertical direction. By selecting appropriate connection holes 13 for fixation, the first fastener passes through the bearing plate 2 and the connection holes 13, and can lock the bearing plate 2 on the vertical pole 1, ensuring that the bearing plate 2 will not shake or displace during construction, and guaranteeing the safety and stability of construction. In addition, in order to adjust the height of the bearing plate 2 itself, the operator can disassemble the first fastener, slide the bearing plate 2 to the required position, and fix the bearing plate 2 by tightening the first fastener, improving the construction efficiency. Among them, the first fastener can adopt screws or pins to achieve the above functions, and will not be limited too much here. Through the above settings, the height of the bearing plate 2 on the vertical pole 1 is adjustable and stably fixed, improving the practicability and adaptability of the extension frame, and enabling the extension frame to flexibly adjust and work stably under different construction environments and height requirements.

[0038] In other embodiments, the bearing plate 2 can be made height-adjustable through a hydraulic cylinder. The bearing plate 2 is slidably connected to the vertical pole 1 in the vertical direction. The output end of the hydraulic cylinder is connected to the bearing plate 2 and can drive the bearing plate 2 to move in the vertical direction. It can be understood that the implementation method of making the bearing plate 2 height-adjustable is not limited here.

[0039] Specifically, as Figures 2 - 4As shown in the figure, the extension frame further includes a second fastener. Along the first horizontal direction, the working board 3 is arranged between two adjacent vertical rods 1. The working board 3 can be locked to the vertical rod 1 through the second fastener, effectively preventing the working board 3 from shaking or displacing during construction, ensuring the safety of construction workers, and thus enhancing the safety and stability of the extension frame during use. In addition, when the operator needs to adjust the height of the working board 3 itself, the position of the working board 3 relative to the vertical rod 1 can be adjusted by disassembling and connecting the second fastener, so as to meet different construction requirements. Among them, the second fastener can be a pin or a screw, and no further limitation is made here.

[0040] Specifically, as Figures 2 - 4 shown in the figure, a cover plate 32 is rotatably arranged on the working board 3. The cover plate 32 covers the passage opening 31, facilitating the operator to open the cover plate 32 and pass through the passage space 11. By closing the cover plate 32, it can effectively prevent operators or tools from accidentally falling from the passage opening 31, improving the safety during construction. Among them, the rotational connection between the cover plate 32 and the working board 3 can adopt methods such as hinge connection or pivot connection, and no further limitation is made here.

[0041] More specifically, as Figures 2 - 4 shown in the figure, a handle 321 is provided on the cover plate 32, facilitating the operator to hold and operate, which is more convenient and fast.

[0042] Specifically, as Figures 2 - 4 shown in the figure, the extension frame further includes a connecting member 6. The connecting member 6 is arranged on the vertical rod 1 and can be detachably connected to the climbing formwork, enabling the extension frame to be stably connected to the climbing formwork, enhancing the stability and safety of the entire construction platform. At the same time, by setting the connecting member 6, the extension frame can be conveniently and quickly connected or disassembled from the climbing formwork to adapt to the changing requirements under different construction environments.

[0043] More specifically, as Figure 2 shown in the figure, in this embodiment, the connecting member 6 includes a U-shaped rod and an angle steel. The two ends of the U-shaped rod are respectively connected to the vertical rod 1 and the climbing formwork through the angle steel. The angle steel and the vertical rod 1 and the climbing formwork can be detachably connected through methods such as screwing or clamping, facilitating the assembly and disassembly of each component. The above components not only have high strength and good stability, but also are convenient for obtaining materials locally. In other embodiments, the connecting member 6 includes a connecting rod, and the two ends of the connecting rod are respectively screwed to the vertical rod 1 and the climbing formwork. That is, the specific structure of the connecting member 6 is not limited, as long as the above functions can be achieved.

[0044] More specifically, to ensure the connection strength and stability between the extension frame and the climbing formwork, a connection part is provided at the top of the column. The connection part is used to connect to the beam structure of the climbing formwork. The connection part includes two flat plates arranged at intervals facing each other. One end of the flat plate is connected to the column, and a through hole is opened at the other end. The connection between the connection part and the climbing formwork is achieved by matching the bolt with the through hole.

[0045] Specifically, as Figures 2 - 5 shown, the climbing ladder 4 includes a plurality of cross bars 41. The plurality of cross bars 41 are arranged at intervals in the vertical direction between two adjacent vertical rods 1, effectively increasing the structural stability of the climbing ladder 4. Each cross bar 41 plays a role in supporting and strengthening, so that the whole climbing ladder 4 can be more stable when bearing the weight of people going up and down.

[0046] More specifically, the climbing ladder 4 further includes connecting plates. The connecting plates are arranged at both ends of each cross bar 41. The connecting plates are screwed to the vertical rods 1 by bolts to increase the contact area between the cross bar 41 and the vertical rod 1, and further ensure the stability of the climbing ladder 4.

[0047] Obviously, the above-mentioned embodiments of the present invention are only examples for clearly explaining the present invention, and are not intended to limit the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to enumerate all the implementation manners here.
