[0022] Reference Figures 1 to 6 From the structure in the figure, we can understand the implementation process of reducing the volume to facilitate collection in this utility model.

[0023] The utility model provides a kind of construction ladder, including two mirror image setting side column 01, and the inside of each side column 01 is rotatably connected with multiple treadle 04, corresponding two treadle 04 inner end are mutually hinged and the inner end upside of one of treadle 04 is shaped with the limiting piece 06 that face contacts another treadle 04, and the end portion downside of each treadle 04 and side column 01 connection place is the right angle edge 05 that can face contact on the inside of side column 01;By mutually extruding two side column 01, make two side column 01 to the hinged two treadle 04 by outside to inside receive thrust, to make two treadle 04 utilize the hinge of inner end and rotate, and make the hinge of inner end of two treadle 04 and move upward, to make two treadle 04 fold, can make the interval of two side column 01 reduce and multiple treadle 04 are clamped in the middle, to reduce volume, can conveniently store construction ladder, to facilitate carrying and storage, when using, two side column 01 are pulled apart, to make the two treadle 04 that fold up and expand, utilize the right angle edge 05 on treadle 04 and stick to side column 01, to make treadle 04 rotate to the state of being perpendicular to side column 01 side and be limited not to continue rotating again, simultaneously can utilize the limiting piece 06 on one of treadle 04 and contact on another treadle 04, to make two hinged treadle 04 and expand to the same plane and keep consistent, can when user is stepped on two treadle 04 can stably support user.

[0024] Refer to Figures 1 to 6 , can be understood from the structure in the drawing that one implementation process in the utility model is stably supported on ground,

[0025] The side column 01 is provided with an inner groove 02, the inner wall outside the upper end of the inner groove 02 is rotatably connected with a vertical plate 07, the inner wall inside the lower end of the inner groove 02 is rotatably connected with a horizontal plate 08, the vertical plate 07 and the horizontal plate 08 can be retracted into the inner groove 02, and the end portions of the vertical plate 07 and the horizontal plate 08 are hinged by a pin shaft 09; when in use, the vertical plate 07 and the horizontal plate 08 in each inner groove 02 can be rotated out, and the end portions of the vertical plate 07 and the horizontal plate 08 are aligned before the pin shaft 09 is connected, so that the positions of the vertical plate 07 and the horizontal plate 08 are fixed, which can make the horizontal plate 08 contact the ground when in use to incline the construction ladder, and the vertical plate 07 can be used to support and increase the stability of the side column 01, which can avoid the construction ladder from falling down after erection, and avoid the safety hazard caused by the end portion sliding and making the construction ladder fall down when the traditional construction ladder is used by inclining against the wall;

[0026] The vertical plate 07 and the horizontal plate 08 in the same inner groove 02 are rotated out and hinged with the pin 09 to be perpendicular to each other; after the horizontal plate 08 contacts the ground, the vertical plate 07 can be kept perpendicular to the ground, and the vertical plate 07 can be kept in a vertical state to increase the stress-bearing strength of the vertical plate 07, thereby further improving stability and stress-bearing capacity;

[0027] After use, the pin 09 is pulled out, and the vertical plate 07 and the horizontal plate 08 can be rotated and retracted into the inner groove 02, so that the vertical plate 07 and the horizontal plate 08 and the side column 01 are kept in the same straight line for storage.

[0028] Reference Figures 1 to 6 From the structure in the figure, we can understand the implementation process of increasing the stabilization effect of the utility model.

[0029] The cross brace 10 further includes a clamping slot 11 at both ends. The two clamping slots 11 can be clamped on the two vertical plates 07 respectively to mount the cross brace 10 on the two vertical plates 07. When in use, the two clamping slots 11 at both ends of the cross brace 10 are clamped on the two vertical plates 07 respectively, so that the cross brace 10 restrains the two vertical plates 07 in the horizontal direction, thereby preventing the two vertical plates 07 from bending in the horizontal direction and being damaged.

[0030] Two protrusions 03 are formed on the outer wall of the side column 01, and two card slots 11 can be clipped onto the two protrusions 03 to hang the cross brace 10 on the outer side of the side column 01; after use, the two card slots 11 are clipped onto the two protrusions 03 to achieve the effect of hanging the cross brace 10 on the side column 01, which is convenient for carrying and storage.

[0031] Reference Figures 1 to 6 From the structure in the figure, we can understand the implementation process of increasing the anti-slip effect of the utility model.

[0032] The upper surface of the pedal 04 is paved with a non-slip rubber pad to prevent the user's feet from slipping and causing safety hazards;

[0033] The upper surface of the pedal 04 is provided with anti-skid grooves to increase the friction between the pedal and the sole of the user, thereby playing an anti-skid role.

[0034] Reference Figures 1 to 6 From the structure in the figure, we can understand the implementation process of reducing weight in the utility model.

[0035] The side columns 01, pedals 04, uprights 07, cross plates 08 and cross braces 10 are all made of aluminum alloy. Utilizing the characteristics of aluminum alloy, which is light in weight and high in strength, the overall weight can be reduced while still maintaining better strength to avoid deformation.
