Technical Field
[0001] The utility model relates to the field of building construction, in particular to a ladder for a sump. Background Art
[0002] A sump is a common construction method that needs to be set up when the groundwater level is high and the base elevation is below the groundwater level during the excavation of the foundation pit. During the construction process, a ladder is usually set up in the hanging sump, which is mainly used for personnel to climb up and down the sump for inspection and cleaning during the use of the building.
[0003] In the traditional construction process of ladders in sump, the ladders are usually installed and fixed by pre-buried methods. However, the pre-buried ladders must penetrate the waterproof layer, causing local weak points in the waterproof layer and posing a risk of leakage, which needs to be improved. Utility Model Content

[0012] In a preferred example, the utility model can be further configured as follows: the tripod is composed of three angle steels connected end to end and welded to each other.
[0013] In a preferred example, the utility model can be further configured as follows: mounting rods are provided on both sides of the hanging ladder, and mounting hooks and mounting rings are provided on the mounting rods for hanging and storing maintenance tools.
[0014] In a preferred example, the utility model can be further configured as follows: the installation rod is vertically slidably connected to the hanging ladder, and the lower end of the hanging ladder is rotatably connected to a locking rod for supporting the lower end of the installation rod.
[0015] In a preferred example, the present invention can be further configured as follows: a locking groove for the locking rod to be embedded in is provided at the lower end of the mounting rod.
[0016] In summary, the utility model has the following beneficial effects:
[0017] 1. By setting up a hanging ladder, the upper end of the ladder is fixed on the structural wall, and the lower part of the ladder is supported by the feet and against the inner wall of the sump. During the installation of the ladder, the waterproof layer will not be penetrated, which plays a role in protecting the waterproof layer. At the same time, the complete set of prefabricated components can improve the overall aesthetics of the ladder and make it easier to construct;
[0018] 2. All components of the ladder are welded and fixed with angle steel and steel bars, which are easy to obtain. Even discarded steel and steel bars on the construction site can be selected, making the ladder processing more convenient;
[0019] 3. By providing a mounting pole capable of storing maintenance tools, workers can enter the sump for inspection and maintenance anytime and anywhere, and it provides convenience for climbing the ladder as well as inspection and maintenance. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] Figure 2 is a schematic structural diagram of Example 2;
[0022] Figure 3 It is a schematic structural diagram of the mounting rod of Example 2.
[0023] Figure numerals: 1, tripod; 2, hanging ladder; 21, vertical beam; 22, horizontal beam; 3, support leg; 4, mechanical anchor bolt; 5, pad; 6, mounting rod; 61, locking groove; 7, mounting hook; 8, mounting ring; 9, locking rod. DETAILED DESCRIPTION
[0024] The utility model is further described in detail below in conjunction with the accompanying drawings.
[0025] Embodiment 1:
[0026] like Figure 1 As shown, a ladder for a sump includes a tripod 1, a hanging ladder 2, and a support leg 3. The tripod 1 is arranged in a right triangle shape with the hypotenuse facing outwards. The vertical right-angled side of the tripod 1 abuts against the structural wall and is fixed to the structural wall by a mechanical anchor bolt 4. The upper end of the hanging ladder 2 is fixed to the intersection of the horizontal right-angled side and the hypotenuse of the tripod 1, and extends downward into the sump.
[0027] like Figure 1 As shown, the support leg 3 is arranged at the lower end of the hanging ladder 2 and contacts the inner wall of the sump. The support leg 3 is divided into two layers and is distributed on both sides of the two lowest climbing positions of the hanging ladder 2. A pad 5 is arranged at one end of the support leg 3 contacting the inner wall of the sump to reduce the pressure on the inner wall of the sump, prevent pressure loss, and protect the waterproof layer from being airtight.
[0028] Therefore, by setting a hanging ladder, the upper end of the ladder is fixed on the structural wall, and the lower part of the ladder is against the inner wall of the sump through the support legs 3, so that the waterproof layer will not be penetrated during the installation of the ladder, thereby protecting the waterproof layer from being sealed. At the same time, the complete set of prefabricated components can improve the overall aesthetics of the ladder and make it easier to construct.
[0029] like Figure 1 As shown, the tripod 1 is composed of three angle steels connected end to end and welded to each other, and the hanging ladder 2 includes a pair of vertical beams 21 and multiple horizontal beams 22. The vertical beams 21 are angle steels, and the horizontal beams 22 are steel bars. The horizontal beams 22 are welded and fixed to the inner side of the vertical beams 21. The support legs 3 and the pads 5 are both angle steels and welded to each other.
[0030] Since all components of the ladder are welded and fixed with angle steel and steel bars, it is easy to obtain materials and convenient to produce and process. Even discarded steel and steel bars at the construction site can be selected, making the processing of the ladder more convenient.
[0031] Embodiment 2:
[0032] like Figure 2 , Figure 3 As shown, both sides of the hanging ladder 2 are provided with mounting rods 6, and mounting hooks 7 and mounting rings 8 are provided on the mounting rods 6 for hanging and storing maintenance tools. The mounting rods 6 are vertically slidably connected to the hanging ladder 2, and the lower end of the hanging ladder 2 is rotatably connected to a locking rod 9 for supporting the lower end of the mounting rod 6, and the lower end of the mounting rod 6 is provided with a locking groove 61 for the locking rod 9 to be embedded.
[0033] Therefore, during the installation of the ladder, various tools can be placed on the mounting hook 7 or the mounting ring 8 as needed to realize the hanging storage of the tools. Therefore, when the sump needs to be inspected or repaired, the workers can directly enter the sump without carrying heavy inspection tools, which provides convenience for the workers' climbing, inspection and repair.
[0034] And when it is necessary to carry out maintenance in the sump, the installation rod 6 can be pushed to slide upward, and then the locking rod 9 can be rotated to make the locking rod 9 detach from the lower end of the hanging ladder 2, and then the tools carried by the installation rod 6 can slide downward under the action of gravity, so that workers can take the tools conveniently without climbing to take the tools, which provides convenience for workers' inspection and maintenance.
[0035] And when the inspection and maintenance are completed, push the installation rod 6 to move upward, then rotate the locking rod 9 so that the locking rod 9 is located below the installation rod 6, and then loosen the installation rod 6 so that the locking rod 9 is embedded in the locking groove 61 at the lower end of the installation rod 6, so that the installation rod 6 can be supported and fixed to ensure that the tool will not fall.
[0036] The specific embodiments are merely explanations of the present invention and are not limitations of the present invention. After reading this specification, those skilled in the art may make modifications to the embodiments without any creative contribution as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
