Problems solved by technology

[0002] At present, the ladders used in building construction are mostly composed of steel pipes and fasteners. Since the fasteners and steel pipes rely on friction, the safety is low, the cost is high, the installation is complicated, and the stability is poor, especially when the height is high.
Another kind of ladder is composed of portal scaffolding, which covers a large area and can only be used within a height of 10 meters. Although the cost is low, the stability is poor, the safety is poor, and it cannot be disassembled. One use is not easy to be unlucky, and there are great limitations in use

Embodiment 1

[0051]As shown in Figures 1 to 8, the safety ladder of this embodiment includes a ladder foundation 1, and the ladder foundation 1 can be a 2.5×3.5×0.2m C25 concrete floor, or four 0.5×0.5×0.4m C25 concrete columns, And keep the surface level. The ladder foundation 1 is connected to the main body of the ladder through the base 2, and the base 2 and the ladder foundation 1 are anchored by expansion bolts. The base 2 includes an anchor plate, and the middle part of the anchor plate is provided with two fastened main rods and inner rods, both of which are L-shaped metal rods, and an outer end plate is arranged on the upper part of the fastened main rod and the inner rod , the middle part is provided with an inner end plate for fixing the main body of the ladder. The main body of the ladder includes a standard section 4, an entrance section 3 and a staircase 5 arranged inside the standard section and the entrance section.

[0052] The entrance section 3 includes four rectangular...

Embodiment 2

[0063] Such as Figure 9 , 10 As shown, the structure of the safety ladder in this embodiment is basically the same as the structure of the safety ladder in Embodiment 1, the difference is that it also includes an anti-throwing net 13 arranged outside the main body of the ladder, and the anti-throwing net 13 is preferably a steel wire mesh . In the middle of the first upper cross bar 8-1, the first mid-slope bar 8-3, the second upper cross bar 9-1 and the third mid-slope bar 9-3, there are steel mesh connection holes for bolts to pass through. The top of the pole 7 is also provided with wire mesh connection holes for bolts to pass through, and the wire mesh is fixed on the outside of the ladder through these wire mesh connection holes by bolts.

[0064] By arranging the enclosure anti-throwing net 13 around the ladder, falling objects can be avoided, and at the same time, people on and off the ladder can be prevented from falling, which improves the safety of the present inv...

Embodiment 3

[0073] Such as Figure 11 , 12 As shown, the structure of the safety ladder of this practical example is basically the same as that of the safety ladder of Embodiment 1, the difference is that it also includes an attachment 14 arranged on the standard section 4 . When climbing ladder every rises 4-6m, can be provided with a connecting wall member, utilize building pull bar to be connected with attachment 14, if connecting wall member is not done well, cable wind rope can be set on the pole. The safety and stability of the present invention are further enhanced by providing the attachment 14 for attachment and connection with surrounding buildings.

[0074] In this embodiment, on the premise of ensuring the stability of the safety ladder, the safety ladder can be attached to the building by setting the attachment to prevent the safety ladder from tilting.

[0075] The installation method of the safety climbing ladder of this embodiment is as follows:

[0076] a. Install the ...
