[0002] Reinforcement engineering is a crucial aspect of building construction, and the quality of rebar fabrication and tying determines the quality of the building structure. In current technology, the surface reinforcement of structures such as floor slabs or foundations is typically processed in a factory and then transported to the construction site. The rebars are then manually placed one by one, and their position is adjusted along the truss reinforcement joists to meet design requirements. Simultaneously, the rebars are tied and secured. This process requires positioning, adjusting, and tying a large number of surface reinforcement bars, which is not only labor-intensive but also inconvenient and physically demanding, resulting in low construction efficiency. Consequently, it consumes significant manpower and time, severely impacting the progress and cost of the construction project. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a surface steel bar winding device, which reduces the difficulty of operation for workers, greatly reduces the workload, and thus significantly improves the efficiency of steel bar construction and reduces construction costs.

[0008] Furthermore, the positioning pin is centrally symmetrical, and the winding reel is provided with a plurality of limiting holes adapted to the positioning pin. The positioning pin can be selectively inserted into part of the limiting holes so that the handle is misaligned with the reinforcing bar.

[0009] Furthermore, the winding reel includes a grid frame, which includes several parallel horizontal bars and several parallel vertical bars, and the horizontal bars and vertical bars are connected in an alternating manner to form the limiting holes.

[0010] Furthermore, the winding reel also includes arc-shaped edges, which are circumferentially spaced on the grid frame, and openings of the fixing groove are formed between adjacent arc-shaped edges.

[0029] The embodiments of this utility model will now be described with reference to the accompanying drawings.

[0030] This utility model proposes a surface steel bar winding device, which winds up the surface steel bars into a coil and transports them to the construction site for laying. Compared with the existing technology of manually positioning and adjusting each bar one by one, this device reduces the difficulty of operation for workers, significantly reduces the workload, and thus significantly improves the efficiency of steel bar construction and reduces construction costs.

[0031] like Figure 1 , Figure 2 As shown, this utility model provides a surface steel bar winding device, including a central support 1, with winding discs 11 at both ends of the central support 1 along the axial direction, and a plurality of fixing grooves 111 with openings on the edge of the winding discs 11. Two corresponding fixing grooves 111 on two winding discs 11 can fix a steel bar 21. By rotating the winding discs 11, a steel mesh 2 composed of a plurality of steel bars 21 can be wound up.

[0032] like Figure 3 As shown, the reinforcing mesh 2 includes several parallel reinforcing bars 21 arranged at predetermined intervals, and the reinforcing bars 21 are connected together by binding members 22. Typically, the surface reinforcing bars 21, which are usually installed in building structures such as floor slabs or foundation raft slabs, are distributed in layers along the thickness direction of the structure. Each layer of reinforcing bars 21 includes several parallel reinforcing bars 21, and the reinforcing bars 21 maintain a predetermined spacing. This spacing can be uniform or evenly distributed, or it can be arranged at different intervals according to different needs. In a specific embodiment of this application, the surface reinforcing bars 21 used in the building structure are arranged at equal intervals. The reinforcing mesh 2 includes several reinforcing bars 21, and the binding members 22 are evenly distributed along the length direction of the reinforcing bars 21. Each binding member 22 connects several reinforcing bars 21. The binding members 22 are made of galvanized steel wire or flamed iron wire, which has good strength and corrosion resistance, and can firmly bind the reinforcing bars 21 together, preventing the reinforcing bars 21 from falling off.

[0033] like Figure 2 As shown, the axial support 1 in this application also includes a central connecting rod 12. The two ends of the central connecting rod 12 are respectively connected to two winding reels 11, so that the fixing slots 111 on the two winding reels 11 correspond one-to-one. The line connecting the fixing slots 111 is parallel to the length direction of the central connecting rod 12. The central connecting rod 12 is located inside the winding reel 11 relative to the fixing slots 111, and has good rigidity. This allows the two parts of the reinforcing bar 21 along its length to be embedded in the two fixing slots 111 and parallel to the central connecting rod 12. Simultaneously, the binding member 22 is fixed around the outside of the central connecting rod 12, so that during subsequent winding, the reinforcing bar 21 can be tightly fitted to the inner reinforcing bar 21 and the binding member 22, effectively limiting the movement of the inner reinforcing bar 21. Furthermore, through this design, the reinforcing bars 21 on the same winding reel 11 remain parallel, ensuring the stability and accuracy of the winding process.

[0034] In this application, the central connecting rod 12 can be a rod-shaped member with a large diameter or multiple rod-shaped members to connect different parts of the middle winding reel 11. When multiple rod-shaped members are used, the rod-shaped members are evenly distributed around the axis of the winding reel 11 so that the two winding reels 11 are subjected to uniform force and the overall stability of the axis support 1 is ensured.

[0035] In this application, the winding of the reinforcing mesh 2 is completed by rotating the central support 1. To achieve the rotation of the central support 1, it can be done manually or by using an electric rotating device such as a servo motor; no limitation is made here. In one specific embodiment, to ensure precise and controllable rotation, the central support 1 is rotated manually, such as... Figure 4 As shown, the surface steel bar 21 winding device proposed in this application also includes a rotating component 3 for driving the winding reel 11 to rotate; the rotating component 3 includes a handle 32 and a positioning pin 31 disposed at one end of the handle 32. The positioning pin 31 can be inserted into the winding reel 11 and extend the handle 32 to the outside of the winding reel 11. By manually rotating the handle 32, the axial support 1 can be driven to rotate around its axis, thereby winding up the steel mesh 2 layer by layer.

[0036] like Figure 1 , Figure 4As shown, the positioning pins 31 are arranged symmetrically at the center. The winding reel 11 is provided with several limiting holes 113 that are adapted to the positioning pins 31. The positioning pins 31 can be selectively inserted into some of the limiting holes 113 to make the handle 32 and the reinforcing bar 21 staggered. Specifically, there are at least two positioning pins 31. When in use, the two positioning pins 31 are inserted into the corresponding limiting holes 113 respectively. At this time, the handle 32 is perpendicular to the reinforcing bar 21. When the positions of the handle 32 and the reinforcing bar 21 conflict during the winding process, the rotating part 3 can be pulled out, and after rotating the locking part, the positioning pin 31 can be inserted into the other hole to continue driving the winding reel 11 to rotate. Alternatively, when the locking part drives the winding reel 11 to rotate 180 degrees, and the handle 32 conflicts with the ground and cannot continue to rotate, the rotating part 3 can be pulled out, rotated 90 degrees or 180 degrees in the opposite direction, and then inserted back into the limiting hole 113. The winding reel 11 can then be driven to rotate again by rotating the handle. The operation is simple and quick, realizing continuous winding operation.

[0037] In a specific embodiment, such as Figure 5 As shown, one end of the rotating component 3 is provided with five positioning pins 31, of which four positioning pins 31 are arranged symmetrically around a centrally located positioning pin 31. This design allows the five positioning pins 31 to still accurately align with the limiting holes 113 on the winding reel 11 when the rotating component 3 rotates 90 degrees or 180 degrees in the forward or reverse direction, thereby enabling continuous winding operations.

[0038] The aforementioned winding reel 11 includes a grid frame 112, which includes several parallel horizontal bars and several parallel vertical bars. The horizontal bars and vertical bars are connected in an alternating manner to form limiting holes 113. The limiting holes 113 are also centrally symmetrical, so that the rotating part 3 can still be aligned with different limiting holes 113 when rotating in the forward or reverse direction at a set angle, thereby realizing hole changing insertion and continuous operation.

[0039] Furthermore, the winding reel 11 also includes arc-shaped edges 114, which are circumferentially spaced on the grid frame 112. An opening of a fixing groove 111 is formed between adjacent arc-shaped edges 114. By setting the arc-shaped edges 114, the outer contour of the overall winding reel 11 presents a circular structure with an opening, which facilitates the shaping and rotation winding of the steel mesh 2.

[0040] Furthermore, the fixing grooves 111 are evenly arranged around the circumference of the winding reel 11. The depth of the fixing grooves 111 is adapted to the diameter of the reinforcing bars 21. The perimeter of the arc-shaped edges 114 between the fixing grooves 111 is the same as the spacing between the reinforcing bars 21. This allows the four reinforcing bars 21 to accurately enter the corresponding fixing grooves 111 when winding begins, thereby significantly improving the shaping effect of the winding reel 11 on the reinforcing mesh 2. This ensures that the reinforcing mesh 2 can maintain a neat and flat state during the winding process, effectively preventing the reinforcing mesh 2 from becoming scattered and deformed during the winding process.

[0041] The roll-up reel 11 in this application can be designed in different forms as needed. Figures 6-7 Two types of winding reels 11 are designed to fit the five locating pins 31 arranged in a centrally symmetrical manner; such as Figure 6 As shown, the grid frame of the coil receiving 11 includes two horizontal bars and two vertical bars, which are vertically connected. An arc-shaped edge 114 is provided at each vertical angle, so that the horizontal bars, vertical bars, and arc-shaped edges 114 form a limiting hole 113 that matches the positioning pin 31. Simultaneously, connecting rods are provided between adjacent horizontal bars and adjacent vertical bars, ensuring that the opening depth of the fixing groove 111 meets the requirements for embedding the reinforcing bar 21. Figure 7 As shown, the grid frame 112 of the reel 11 includes three horizontal bars and three vertical bars. The horizontal bars and vertical bars are vertically connected. The two horizontal bars and the two vertical bars in the middle each form two fixing grooves 111, and a connecting rod is provided to limit the opening depth of the fixing grooves 111. The horizontal bars and vertical bars form a number of limiting holes 113 that are adapted to the positioning pins 31, which makes it easier to insert the rotating part 3 into the new hole after rotation.

[0042] Furthermore, the winding reel 11, the central connecting rod 12, and the rotating component 3 in this application are all made of steel bars 21, which can be made from surplus steel bars 21 or steel bar waste commonly found on construction sites, resulting in low cost.

[0043] A method for coiling and unwinding surface reinforcement 21, such as Figures 8-10 As shown, the above-mentioned surface steel bar 21 winding device specifically includes the following steps:

[0044] S1. Arrange the steel bars 21 according to the set intervals;

[0045] Specifically, the surface steel reinforcement 21 can be divided into several groups according to the size of the laying range of the surface steel reinforcement 21 of the building structure to be constructed, so that the rolled steel mesh 2 formed by each group is easy to hoist and transport; when arranging, the surface steel reinforcement 21 is placed on a fixed plane to ensure that the distance between the steel reinforcement 21 is consistent with the design.

[0046] S2. Use tie-up 22 to connect several steel bars 21 together to form a steel mesh 2;

[0047] In this application, steel wire is used as binding material 22 to bind the same group of reinforcing bars 21. When the reinforcing bar 21 is long, several steel wires are evenly arranged along its length to ensure that the binding is firm.

[0048] S3. Place at least two surface steel bar 21 winding devices on the steel bar 21 located at one end of the steel mesh 2, and tie the end of the binding piece 22 to the surface steel bar 21 winding device so that the steel bar 21 is embedded in the fixing groove of the winding reel 11.

[0049] Specifically, a steel bar 21 at one end of the steel mesh 2 is selected as the starting position for the winding operation, and the steel bar 21 is embedded in the fixing groove of several winding reels 11; at least two surface steel bar 21 winding devices are respectively set close to the end of the steel bar 21, and several other surface steel bar 21 winding devices can be set between them according to the length of the steel bar 21.

[0050] S4. Insert the positioning pin of the rotating part 3 into the limiting hole 113 of the winding reel 11, and turn the handle 32 toward the other end of the steel mesh 2.

[0051] Specifically, each rotating component 3 is operated by a worker to ensure that several winding reels 11 rotate synchronously, so as to avoid the steel bars 21 from twisting due to inconsistent winding progress in different parts of the steel mesh 2.

[0052] When the handle 32 of the rotating part 3 is rotated to an angle that is inconvenient to operate, the rotating part 3 is removed and inserted into the limiting hole 113 in another direction that is convenient to operate, so as to drive the winding reel 11 to rotate continuously until the steel mesh 2 is completely wrapped around the surface steel bar 21 winding device.

[0053] S5. Transport the rolled steel mesh 2 to the construction site, and lay the steel mesh 2 in the preset position by rotating the rotating component 3 in the opposite direction.
