[0004] High labor intensity and low efficiency:

[0005] In the traditional method of laying steel bars, it is usually necessary to manually carry and position the steel bars, which is not only labor-intensive but also inefficient. Due to the heavy weight of steel bars, manual handling not only consumes a lot of physical strength, but also easily leads to operational errors due to fatigue, affecting the construction progress and quality. In addition, the manual laying of steel bars cannot achieve large-scale and rapid laying, and it is difficult to meet the speed and efficiency requirements of modern construction.

[0006] Safety hazards and construction accuracy issues:

[0007] The traditional method of laying steel bars manually has great safety hazards. When carrying steel bars manually, improper operation can easily lead to work-related accidents, posing a threat to the safety of construction workers. At the same time, it is difficult to ensure the accuracy of the spacing and position of steel bars when laying steel bars manually, and problems such as steel bar dislocation and uneven spacing can easily occur, affecting the stability and safety of the building structure.

[0008] Poor adaptability and high maintenance cost:

[0009] Traditional rebar laying equipment often lacks flexibility and is difficult to adapt to construction site requirements of different lengths and shapes. In addition, due to limitations in material selection and design, these equipment are often heavy and difficult to carry and operate, limiting their rapid movement and positioning on the construction site. At the same time, due to limitations in wear resistance and durability, these equipment have high maintenance costs and short service life, increasing construction costs.

Preparation: Check all parts of the steel bar rolling laying device, including the steel bar receiving barrel (1), the rolling bracket, the rolling gear (3), etc., to ensure that all parts are intact; According to the construction requirements, the length of the rolling bracket is adjusted; that is, the end guide rail (11) and the plurality of sections of the middle guide rail (12) on the strip guide rail (201) are fixedly connected by bolts to adapt to different construction sites and steel bar lengths; Spaces are provided between adjacent branch fixing rods (203), the branch fixing rods (203) are inserted into the existing steel bar structure, and then the branch fixing rods (203) are fixed to the existing steel bar structure by iron wires or the like, thereby achieving fixation of the rolling bracket; S2. Steel bar loading: When loading the steel bars, the rotating sleeve (102) is rotated until the rectangular notch 1 (17) corresponds to the rectangular notch 2 (18), that is, when the rectangular notch 2 (18) is rotated to the top, the rotation is stopped, and the retractable sealing cover (19) is opened by the handle (20), and the steel bars are loaded into the steel bar receiving barrel (1) according to the required length and quantity. At this time, the strip notch 1 (101) is blocked by the outer wall of the rotating sleeve (102) to prevent the steel bars from leaking out; After loading is completed, the retractable sealing cover (19) is closed; S3. Laying operation: The rolling gear (3) rotates, the gear meshes with the second rack (7) on the bar guide rail (201), so that the steel bar receiving barrel (1) moves horizontally on the rolling bracket; At the same time, the gear 1 (4) rotates to realize the rotation of the rotating sleeve (102), and when the strip slot 1 (101) corresponds to the strip slot 2 (1022), the steel bar falls from the bottom; During the rotation of the rotating sleeve (102), the strip-shaped slot 1 (101) and the strip-shaped slot 2 (1022) are intermittently matched, thereby achieving uniform distribution of the laid steel bars; During the laying process, the design of the support shaft (103) and the branch fixing rod (203) is used to ensure that the steel bars remain horizontal and avoid misalignment; S4. Finishing work: After laying, the device is folded and stored for easy storage and transportation; The equipment is inspected and maintained to ensure reliability the next time it is used; this includes inspecting the wear of the rolling gear (3) and whether the rotating mechanism between the rotating sleeve (102) and the steel bar containing barrel (1) is operating normally.
