Civil engineering projects are a branch of civil engineering, mainly involving the design, construction and maintenance of buildings.

[0003] In the existing civil construction process, it is necessary to first excavate the foundation pit. When the excavation depth of the foundation pit is deep, in order to facilitate the construction of the workers, a ladder needs to be built between the foundation pit and the slope. The Chinese authorized patent announcement number: CN217001630U records "a safety protection ladder for civil construction safety construction". A support seat is provided at the bottom ends of the two connecting steel columns of the ladder body. The support seat can adjust the angle formed relative to the ladder body under the connection of the rotating member, so that the ladder body can adjust different inclinations. At the same time, a contact piece is provided on the support seat. The bottom end of the ladder body can be made to be in stable contact with the foundation pit ground by adjusting the insertion depth of the anchor rod, thereby further ensuring the stability and safety of the ladder body in connecting the foundation pit and the slope; however, in the application process, there are the following defects and shortcomings: the anchor rod provided can be inserted into the soil to fix the bottom of the ladder, but it is limited to the soil area. If it is used on some cement floors or other sites with hard textures, the anchor rod cannot be used normally; therefore, it is necessary to provide a new safety protection ladder for construction to solve the above technical problems.

[0025] In this structure, a bottom fixing assembly 2 is provided at the lower end of the ladder body 1, and a bite plate 3 is movably installed under the bottom fixing assembly 2. Therefore, when the ladder is used, the bite plate 3 can bite the ground surface, thereby ensuring the stability of the device and preventing sliding. The ladder is not only suitable for soil sites, but also can be used in some cement sites, and has a wider range of applications. Moreover, the bite plate 3 can rotate in any direction to adapt to uneven sites, further improving the scope of application of the device.

[0026] An anti-damage component 6 is also installed at the upper end of the ladder body 1. The anti-damage component 6 serves as a supporting contact structure, so that when the ladder is used, the wear of the ladder body 1 itself can be reduced, its service life can be increased, and the stability will also be higher.

[0027] like Figure 4 As shown, the specific structure of the anti-damage component is as follows: the anti-damage component 6 includes a second mounting plate 61 and a connecting frame 62, the second mounting plate 61 is adapted to the upper end of the side column of the ladder body 1 and is fixedly connected as a whole by bolts, the connecting frame 62 is a D-shaped ring structure, and the middle part of the straight side of the connecting frame 62 is fixedly connected to the upper end of the second mounting plate 61.

[0028] A plurality of anti-skid ridges 7 are evenly distributed on the outer arc surface of the arc-shaped plate 63 of the connecting frame 62, and the anti-skid ridges 7 are in contact with the supporting wall.

[0029] The second mounting plate 61 is a second U-shaped plate with its opening facing upward, and the upper end of the side column of the ladder body 1 is adapted to the U-shaped groove of the second mounting plate 61, and the second mounting plate 61 is detachably fixed to the upper end of the side column of the ladder body 1 by multiple bolts.

[0030] In the anti-damage component 6, the arc plate 63 can replace the ladder body 1 to contact the supporting wall, thereby preventing the ladder body 1 from being worn and increasing its service life. In addition, anti-slip ridges 7 are also provided on the arc plate 63, so when in contact with the wall, the friction is greater and the stability is higher.

[0034] like Figure 2-3 As shown, the engaging disk 3 is an inverted disk-shaped structure, and the lower end of the engaging disk 3 is provided with teeth 4 for engaging with the ground.
