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.

[0029] The purpose of the utility model is to provide a construction work platform to solve the problems existing in the prior art. The work platform is built by using scaffolding and scaffolding boards, and tower materials can be assembled on the work platform at the tower construction site, thereby improving the current problem that it is difficult to assemble tower materials on a steep mountain, and improving the work efficiency of tower construction.

[0030] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0031] like Figures 1 to 7 As shown, the utility model provides a construction platform, including a scaffold and a scaffolding board, wherein the scaffold includes a horizontal rod 3 and a vertical rod 2, the vertical rod 2 is used for vertical support, and the horizontal rod 3 is used for horizontal support. The bottom of the vertical rod 2 is supported on the slope of the mountain 10 through a base 6, and the base 6 can stably bear and support the vertical rod 2 on the slope. The heights of the vertical rods 2 set at different positions of the slope are different to adapt to the changes in the slope. When the length of the vertical rod 2 is not enough, it can be overlapped. The horizontal rod 3 is fixedly installed on the vertical rod 2, and different fasteners can be selected according to needs during connection to ensure the reliability and stability of the connection. The horizontal rod 3 can be installed at multiple locations at different height positions in the height direction of the vertical rod 2, and a sweeping rod 33 is set near the slope. Multiple vertical rods 2 and multiple horizontal rods 3 are combined into a frame structure, so that the scaffold forms a solid whole. The horizontal bar 3 installed near the top of the vertical pole 2 is provided with a scaffolding board. A plurality of scaffolding boards are assembled and overlapped to form a working platform 1 for assembling tower materials. The scope of the working platform 1 should be large enough not only for people to walk, but also for assembling tower materials. The scaffolding board in the middle of the working platform 1 can be provided with a vertical pole 2 at the bottom of the scaffolding board, that is, the vertical pole 2 may not protrude the height of the scaffolding board, so as to be able to form a support for the scaffolding board at the bottom of the scaffolding board, thereby forming a flat working platform 1. The working platform 1 is also provided with a tower body space 11 for the iron tower 20 to pass through. The tower body space 11 can be set within the internal area of ​​the working platform 1, and can also be set in the edge area of ​​the working platform 1.

[0032] The utility model utilizes the vertical pole 2 to support the slope of the mountain 10, utilizes the vertical pole 2 to support the scaffolding board, and the scaffolding board forms the working platform 1, so that the working platform 1 can be built by using the scaffolding and the scaffolding board. At the same time, a tower body space 11 is provided on the working platform 1, and the tower body space 11 can allow the iron tower 20 to pass through, so that the working platform 1 can be used to assemble the tower materials at the construction position of the iron tower 20, which improves the current problem that it is difficult to assemble tower materials on the steep mountain 10, and improves the work efficiency of the construction of the iron tower 20.

[0033] The base 6 may include a pad 62. When supporting the upright pole 2, the upright pole 2 is not directly inserted into the soil layer, but supported by the pad 62 to ensure safety and stability. When the pad 62 is provided, the pad 62 may be provided on the soil surface or the bottom of the pit 30.

[0034] like Figure 5As shown, further, when the pad 62 is set on the top of the pit 30, the pit 30 is provided with a bottom beam 61, and the bottom beam 61 is used to form a support that crosses the pit 30 horizontally, so that the bottom beam 61 can be used to support the pad 62, thereby improving the bearing capacity of the pad 62 and avoiding the pad 62 from breaking. The bottom beam 61 can be made of materials such as sleepers or steel beams.

[0035] Combination Figure 3 As shown, when installing the horizontal rods 3, if different horizontal rods 3 intersect, the long horizontal rod 3 can be placed below the short horizontal rod 3. The horizontal rod 3 can include a crossbar 31 and a longitudinal rod 32 according to the different directions of installation with the vertical rod 2, and the crossbar 31 and the longitudinal rod 32 are connected to the vertical rod 2 in a horizontal and vertical distribution. It should be noted that: the crossbar 31 and the longitudinal rod 32 do not have a definite length relationship, that is, the crossbar 31 can be a long horizontal rod 3 or a short horizontal rod 3, and similarly, the longitudinal rod 32 can also be a long horizontal rod 3 or a short horizontal rod 3.

[0036] like Figure 1 and Figure 2 As shown, the tower space 11 can be set inside the working platform 1. In this case, the tower space 11 is built by a plurality of scaffolding boards around the iron tower 20, so that, through the setting of the working platform 1, construction workers can work around the iron tower 20. More specifically, the tower space 11 can be a hole through which the legs of the iron tower 20 pass.

[0037] like Figure 1 , Figure 3 and Figure 4 As shown, the scaffolding may further include a first diagonal brace 4 and a second diagonal brace 5. The first diagonal brace 4 and the second diagonal brace 5 are different from the vertical poles 2 in that they are arranged diagonally to further enhance the stability of the scaffolding. The first diagonal brace 4 is arranged crosswise to form a scissor brace. The scissor brace may be a single scissor unit, where a single scissor unit is two first diagonal braces 4 arranged crosswise, or may be a plurality of scissor units, such as Figure 3 The form shown. When installing the first diagonal brace 4 in the scissors brace, taking a single scissors unit as an example, one first diagonal brace 4 is buckled on the vertical pole 2, and the other first diagonal brace 4 is buckled on the end of the horizontal pole 3, and is fixed at least at both ends of the first diagonal brace 4. In addition, the first diagonal brace 4 vertically spans at least two layers of horizontal poles 3, so that connections are established between the multiple layers of horizontal poles 3, thereby improving the strength of the overall structure of the scaffolding. The second diagonal brace 5 is arranged slightly differently from the first diagonal brace 4. The second diagonal brace 5 can be connected to the diagonal of the rectangular space enclosed by the vertical pole 2 and the horizontal pole 3, and does not need to span multiple layers of horizontal poles 3, so that it can be set in relatively low-height areas where multiple layers of horizontal poles 3 are not set or in areas that require further structural reinforcement.

[0038] Combination Figure 7As shown, when the horizontal rod 3 is not long enough and the first diagonal brace rod 4 is not long enough, they can be overlapped to extend the length to meet the needs of scaffolding construction. When the horizontal rod 3 overlaps the horizontal rod 3, the overlap length is not less than 1m, and at least two rotating fasteners 41 are used to fix. When the first diagonal brace rod 4 overlaps the first diagonal brace rod 4, the overlap length is not less than 1m, and at least two rotating fasteners 41 are used to fix.

[0039] A guy 51 may also be provided, one end of which is connected to the upright pole 2 and the other end of which is supported on the slope, so as to support the scaffold and avoid and prevent the scaffold from overturning.

[0040] Combination Figure 6 As shown, it can also include a wall connecting piece, which is used to further fix the scaffolding to the slope of the mountain 10. The wall connecting piece includes a wall connecting rod 9 and an embedded rod 91. The embedded rod 91 is fixed to the slope through an embedded foundation 92. The embedded foundation 92 can be a permanent foundation for pouring concrete, which can improve the stability of the connection with the slope. When connecting, one end of the wall connecting rod 9 is connected to the vertical rod 2, and the other end of the wall connecting rod 9 is connected to the embedded rod 91.

[0041] like Figure 1 and Figure 3 As shown, the part of the vertical pole 2 that is higher than the working platform 1 can be used as a vertical protective rod. The vertical protective rod is vertically connected with at least two layers of horizontal rods 3. The horizontal rods 3 serve as horizontal protective rods. The vertical protective rods and the horizontal protective rods are combined to form a protective structure to prevent workers and tower materials from falling.

[0042] A footboard 8 can be provided near the vertical protection bar near the working platform 1, and a protective net 7 is provided within the range of the vertical protection bar. The combination of the footboard 8 and the protective net 7 further ensures the safety of the workers on the working platform 1, while effectively avoiding the risk of tower materials or other equipment falling.

Taking the CN6 pile position as an example, the front side of the pile position is a canyon with a drop of more than 300 meters. The height difference between the highest C leg and the lowest A leg is 11 meters. Due to the large slope, it is very difficult for personnel to stand. The left side of the tower position is the 110kV Hu Lihe line, the right side is the 110kV Lihe line, and the right front side is the 35kV He Tianrui line. It is located in a narrow strip sandwiched between three operating lines.

Through overall planning, the project department set up the construction platform of the pile position one week before the tower assembly. After the tower assembly team entered the site, it took only 3 days to hoist and overhaul the tower. If the tower assembly is not carried out by loose hoisting with a facility work platform, the tower assembly is expected to be completed in 9-11 days.
