Claims

1. A chimney wall construction ladder characterised in that: The system includes several embedded parts (1) embedded in the cylinder wall, a construction ladder (2) installed on the embedded parts, and a guardrail (3) installed on the side of the construction ladder away from the cylinder wall. The embedded parts (1) are arranged in two rows along the height direction of the cylinder wall, and the two rows of embedded parts (1) are symmetrical. The embedded parts (1) include an embedded plate (101), multiple L-shaped embedded steel bars (102) welded to one side of the embedded plate, a square steel pipe (103) welded to the other side of the embedded plate, and positioning blocks (104) welded to the top and bottom surfaces of the steel pipe. The embedded steel bars (102) are embedded in the cylinder wall. The construction ladder (2) is located between two rows of embedded parts (1). Several first sliding sleeves (4) are slidably connected on both sides of the construction ladder (2). The first sliding sleeve (4) has a first screw hole on the side near the positioning block. The first sliding sleeves (4) are in pairs. The two first sliding sleeves (4) in the same group are connected to the two positioning blocks (104) of the same steel pipe (103) by bolts. Several second screw holes are opened on the side of the construction ladder (2) away from the cylinder wall. The guardrail (3) has an arched cross section, and one end of it is connected to the construction ladder (2) through the cooperation of bolts and a second screw hole.

2. A chimney wall construction ladder according to claim 1, characterised in that: The positioning block (104) has a strip hole (105) that matches the first screw hole.

3. A chimney wall construction ladder according to claim 2, characterised in that: The guardrail (3) includes several arched rods (301) arranged vertically, and connects all the arched rods to multiple vertical rods (302). The two ends of the arched rods are connected to connecting plates (303), and the connecting plates (303) are provided with third screw holes that match the second screw holes.

4. A chimney wall construction ladder according to claim 3, characterised in that: The construction ladder (2) is also slidably connected to the two sides of the second sliding sleeve (5), and the side of the second sliding sleeve (5) near the cylinder wall is connected by bolts to a support mechanism (6) that contacts the cylinder wall.

5. A chimney wall construction ladder according to claim 4, characterised in that: The support mechanism (6) includes an outer tube (601), an inner tube (602) slidably connected to the outer tube, a first flange (603) connected to one end of the outer tube, and a second flange (604) connected to one end of the inner tube. The first flange (603) is bolted to the second sliding sleeve (5). A fourth screw hole is provided on the outer side of the embedded plate (101), and the second flange (604) is bolted to the fourth screw hole.

6. A chimney wall construction ladder according to claim 5, characterised in that: The outer tube (601) has a fifth screw hole, and the inner tube (602) has multiple sixth screw holes that mate with the sixth screw hole. The inner tube (602) is fixed to the outer tube (601) by bolts, the fifth screw hole and the sixth screw hole.
