[0024] like Figure 2 As shown, at least two long steel pipes 4 are provided, and at least three socket steel pipes 5 are provided. The inclination angles of the vertical steel pipes 2 of the stair formwork frame of the socket steel pipes 5 are consistent, and one long steel pipe 4 is welded and installed every 0.6 meters of the socket steel pipe 5. The long steel pipe 4 and the inclined angle of the formwork 1 are consistent. By welding the long steel pipe 4 and the socket steel pipe 5 together, the edge protection can be played on one side of the stairwell of the concrete structure construction layer.

[0025] like Figure 2As shown, the bottom end of the socket-type steel pipe 5 is further welded with a socket-type sleeve 6, and the socket-type sleeve 6 is inserted into the vertical steel pipe 2 of the stair formwork. By inserting the socket-type sleeve 6 into the vertical steel pipe 2 of the stair formwork, the installation of the long steel pipe 4 and the socket-type steel pipe 5 after welding is facilitated, and this method is convenient for turnover use on the working floor of the stairwell.

[0026] like Figure 3 As shown, the two ends of the large-diameter circular steel bar 8 are movably installed in the two ends of the short steel pipe 7, and the two ends of the large-diameter circular steel bar 8 are rotated in the short steel pipe 7 to be used as a flip member;

[0027] like Figure 4 As shown, two rectangular steel bars 9 are provided, which are symmetrical on both sides, and at least three square steel bases 10 that can fit with the template 1 are welded and installed on the bottom surface of the rectangular steel bars 9. A number of horizontal steel treads 11 are also welded and installed between the rectangular steel bars 9. Through the steel treads 11 welded between the rectangular steel bars 9, construction workers can go up and down through the access stairs, and can also protect the finished templates constructed in the stairwell to avoid damage to the templates by humans.

[0028] like Figure 3 and Figure 4 As shown, the short steel pipe 7 is welded and fixed to the socket steel pipe 5, and the large diameter circular steel bar 8 is welded and fixed to the square steel base 10 on the right side. When the rectangular steel 9 is flipped, the two ends of the large diameter circular steel bar 8 will rotate inside the two ends of the short steel pipe 7.

[0029] It should be noted that the utility model is a staircase device for accessing the construction layer of a concrete structure, which is composed of at least three socket-type steel pipes 5 connected with two long steel pipes 4. Figure 2 The structure has two long steel pipes 4 with an inclination angle that is basically consistent with the angle of the stair slope. A stair formwork vertical steel pipe 2 is set every 0.6m high to ensure that the height of the guardrail can be ≥1.2m. The short steel pipe 7 is welded with a large diameter circular steel bar 8 to form a "circular disconnected" large diameter circular steel bar combination. Figure 3 The structure is composed of two rectangular steel bars 9 and a welded rectangular mesh of steel treads 11. The rectangular mesh of steel treads 11 is welded in a horizontal direction. At least three square steel bases 10 that can fit the template of the stairwell working layer are welded on each rectangular steel bar 9 to form a staircase. Figure 4 The structure uses horizontal steel pipes to connect the stair formwork fasteners to the stairwell, and the vertical steel pipes are connected to the horizontal steel pipes to form a "cross shape" from the stairwell. Figure 2 The number and spacing of the socket steel pipes 5 are consistent, ensuring that the socket steel pipes 5 can be directly inserted into the vertical steel pipes 2 of the stair formwork through the socket sleeves 6 at the bottom. Figure 2The structure is inserted into the vertical steel pipe 2 of the stair formwork extending out of the stairwell to form the edge protection of the stairwell working layer. Figure 4 The structure is placed on the slope of template 1, according to Figure 4 The height of the structure and formwork 1 will Figure 3 One side of the short steel pipe 7 in the structure is welded in sequence Figure 2 The socket-and-socket steel pipe 5 of the structure is finally Figure 4 Structure close to Figure 2 On one side of the short steel pipe 7 of the structure, check the position and Figure 4 One side of the rectangular steel 9 in the structure is connected to Figure 3 The large diameter circular steel bars 8 in the structure are welded in sequence.

It can also protect the finished formwork 1 of the staircase to prevent it from being damaged by human factors.

[0031] During the installation of staircase reinforcement, Figure 4 The access staircase structure is temporarily flipped to Figure 2 The guardrails of the structure are temporarily fixed to provide a working surface for the reinforcement workers to install the stair reinforcement. When people pass through, the guardrails can be temporarily fixed to provide a working surface for the reinforcement workers to install the stair reinforcement. Figure 4 The staircase structure is flipped to one side of the formwork to protect the finished steel bars of the stairs and prevent people from stepping on the steel bars;

[0032] During the stair tread formwork support period, the same method used during the steel bar installation is used to allow construction workers to pass up and down, which can protect the stair tread formwork and prevent people from stepping on the stair tread formwork.

At the same time, the upper staircase mechanism 3 that has been poured can be installed in time.
