Description

Technical Field

[0001] The utility model relates to the technical field of steel tube concrete column or steel column construction, in particular to a pedestrian ladder used for square steel tube columns. Background Art

[0002] Vertical steel pipe columns are structures made of steel and are a major type of building structure. Steel pipe columns are generally tall and are widely used in large factories, stadiums, and high-rise buildings. Ladders are widely used during their construction. Traditional ladders are often difficult to install, are bulky, and are located far from the steel pipe columns. This makes installation very inconvenient for workers, requiring the construction of scaffolding and other operating platforms around the columns to carry out work at the top. This cumbersome construction process is costly and poses safety risks, placing increasingly stringent demands on the construction process.

[0003] The existing steel pipe column safety ladder has a large structure and is usually supported by hanging steel pipes, fasteners, and jacking into the pile and then setting up a frame inside the pile. Different fixed-size frames need to be set up for different pile diameters. It is not reusable, time-consuming, labor-intensive, and inefficient. The length of the steel pipe needs to be cut according to the size of the pile, which is not environmentally friendly.

[0004] Therefore, there is an urgent need for a pedestrian ladder for square steel pipe columns that is reusable, easy to assemble and disassemble, and has controllable costs. Utility Model Content

[0005] The utility model aims to provide a pedestrian ladder for square steel pipe columns, so as to solve the technical problems in the prior art that steel pipe column safety ladders have a bulky structure and are difficult to erect.

[0021] The utility model can also realize a reliable connection between the ladder unit and the steel pipe column through the second column holding member; when the lap height of the ladder unit is relatively high, the second column holding member and the support column are sleeved to fix the ladder unit and the steel pipe column more safely and reliably.

[0022] Optionally or preferably, the auxiliary support rod is a telescopic structure.

[0023] Optionally or preferably, the pedal is a retractable structure.

[0024] The telescopic structure of the utility model enables the pedestrian ladder to be applicable to steel pipe columns of different sizes, thereby improving the practicability of the ladder.

DETAILED DESCRIPTION

[0034] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0035] Example 1:

[0036] See also Figures 1 to 4 A pedestrian ladder for square steel pipe columns includes a plurality of connected ladder units 10, auxiliary support rods 20 for auxiliary supporting the above ladder units 10, and a column holding assembly 30 for fixing the ladder units 10 and the steel pipe columns 40.

[0037] In this embodiment, the steel pipe column 40 is a square steel pipe column. The ladder unit 10 includes a pair of support columns 11 and a pedal 12 disposed between the support columns 11. Both ends of the pedal 12 are fixedly connected to the support columns 11. The pedal 12 is used to fix the support columns 11 and provide support for stepping on. To better accommodate steel pipe columns 40 of different sizes and models, the pedal 12 in this embodiment is a retractable structure.

[0038] In this embodiment, the auxiliary support rod 20 is arranged corresponding to the support column 11. Specifically, the auxiliary support rod 20 is arranged on one side of the support column 11 and is reliably fixed to the ground. The support column 11 and the adjacent auxiliary support rod 20 are fixedly connected by a connecting piece 21.

[0039] In this embodiment, the auxiliary support rod 20 is also a retractable structure, and the overlapping height of the ladder unit 10 can be adjusted according to the actual height of the steel pipe column 40. Accordingly, the height of the auxiliary support rod 20 can also be adjusted with the overlapping height of the ladder unit 10.

[0040] In this embodiment, adjacent ladder units 10 are stacked by support columns 11 and fixed by connecting member 2 13 , which is also fixedly connected to connecting member 1 21 to achieve fixation between the support columns 11 and the auxiliary support rods 20 .

[0041] In order to further improve the stability and safety of the ladder unit 10, in this embodiment, a column assembly 30 is further provided, which is used to fix the ladder unit 10 and the steel pipe column 40; specifically, when 3-6 ladder units are provided, a group of column assemblies 30 should be provided accordingly, and each group of column assemblies 30 should include at least two column members 31.

[0042] The support column 11 is provided with a fixing hole 14 , and the column assembly 30 can be fixedly connected to the support column 11 through the fixing hole 14 .

[0043] See also Figure 4 In this embodiment, the column holding assembly 30 includes a column holding member 31. One end of the column holding member 31 that is connected to the support column 11 is in an arc-shaped hook shape, so that the column holding member 31 can better hook the support column 11. The other end of the column holding member 31 is in a right-angled hook shape, which is also used to hook the square steel pipe column 40.

[0044] Since one end of the column holding member 31 is in an arc-shaped hook shape, it is convenient for operators to quickly disassemble and assemble the column holding member 31, and is more suitable for fixing low and medium height ladder units 10.

[0045] In order to adapt to different sizes of steel pipe columns 40, in this embodiment, the middle section of the column holding member 31 is also a telescopic structure.

[0046] The retractable structure described in this embodiment can be a retractable rod structure including a spring buckle. Technicians can choose it according to actual work needs, so it is not described in detail.

[0047] Example 2:

[0048] The difference between this embodiment and the first embodiment is that a column assembly 30 suitable for a ladder unit 10 of a higher height is provided.

[0049] In this embodiment, the column holding assembly 30 is a column holding member 2 32, one end of the column holding member 2 32 is circular and is sleeved on the support column 11, and the other end is connected to the adjacent side column holding member 2 32 through a connecting member 33. The operator can adjust the clamping degree of the column holding members 2 32 on both sides by adjusting the connecting member 33.

[0050] Compared with the first embodiment, the second column holding member 32 proposed in this embodiment is more reliably fixed, but the disassembly and assembly is relatively complicated, and is suitable for fixing the ladder unit 10 at a higher height.

[0051] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
