[0040] The embodiments of the present invention are described below with reference to the accompanying drawings.

[0041] The present invention proposes a surface layer steel bar winding device, which can roll up the surface layer steel bars and transport them to the construction site for laying in rolls. Compared with the manual positioning and adjustment of each steel bar one by one in the prior art, the operation difficulty of the workers is reduced and the workload is greatly reduced, thereby significantly improving the efficiency of steel bar construction and reducing construction costs.

[0042] like Figure 1 , Figure 2 As shown, the present invention provides a surface layer steel bar winding device, including an axial support 1, and winding discs 11 are provided at both axial ends of the axial support 1. The edges of the winding discs 11 are provided with a plurality of fixing grooves 111 with openings. The two corresponding fixing grooves 111 on the two winding discs 11 can fix a steel bar 21, and the steel mesh 2 composed of a plurality of steel bars 21 can be wound by rotating the winding discs 11.

[0043] like Figure 3 As shown, the steel mesh 2 includes a plurality of steel bars 21 arranged in parallel at set intervals, and the steel bars 21 are connected together by ties 22. The surface steel bars 21 usually arranged in a building structure such as a floor slab or a foundation raft are distributed in layers along the thickness direction of the structure, and each layer of steel bars 21 includes a plurality of parallel steel bars 21. The steel bars 21 maintain a preset spacing, and can be evenly arranged at equal intervals, or can be arranged at different intervals according to different needs. In a specific embodiment of the present application, the surface steel bars 21 used for the building structure are arranged at equal intervals, the steel mesh 2 includes a plurality of steel bars 21, and the ties 22 are evenly arranged along the length direction of the steel bars 21, and each ties 22 connects a plurality of steel bars 21; the ties 22 are made of galvanized steel wire or flame-burned iron wire, which has good strength and corrosion resistance, and can firmly bind the steel bars 21 together to prevent the steel bars 21 from falling off.

[0044] like Figure 2 As shown, the axial support 1 in the present application also includes a central connecting rod 12, and the two ends of the central connecting rod 12 are respectively connected to the two winding disks 11, so that the fixed grooves 111 on the two winding disks 11 correspond to each other, and the line between the fixed grooves 111 is parallel to the length direction of the central connecting rod 12; the central connecting rod 12 is located on the inner side of the winding disk 11 relative to the fixed groove 111, and has good rigidity, so that the two parts of the steel bar 21 along the length direction are respectively embedded in the two fixed grooves 111 and are parallel to the central connecting rod 12, and at the same time, the binding piece 22 is fixed around the outer side of the central connecting rod 12, so that when the steel bar 21 is subsequently wound, it can be tightly attached to the inner steel bar 21 and the binding piece 22, so as to effectively limit the inner steel bar 21. Furthermore, through this design, the steel bars 21 on the same winding disk 11 are kept in parallel arrangement, ensuring the stability and accuracy of the winding process.

[0045] In the present application, the central connecting rod 12 can be a rod-shaped component with a larger diameter or multiple rod-shaped components connecting different parts of the middle part of the central winding drum 11. When multiple rod-shaped components are used, the rod components are evenly distributed around the axis of the winding drum 11 so that the two winding drums 11 are evenly stressed, ensuring the overall stability of the axial support 1.

[0046] In the present application, the steel mesh 2 is rolled up by rotating the axis support 1. To realize the rotation of the axis support 1, manual rotation or electric rotation devices such as servo motors can be used for rotation, which is not limited here. In a specific embodiment, in order to ensure that the rotation process is accurate and controllable, the axis support 1 is rotated manually, such as Figure 4 As shown, the surface layer steel bar 21 winding device proposed in the present application also includes a rotating member 3 for driving the winding drum 11 to rotate; the rotating member 3 includes a handle 32 and a positioning pin 31 arranged at one end of the handle 32, the positioning pin 31 can be plugged into the winding drum 11, and the handle 32 can be extended to the outside of the winding drum 11, and by manually rotating the handle 32, the axial support 1 can be driven to rotate around its axis, thereby rolling up the steel mesh 2 layer by layer.

[0047] like Figure 1 , Figure 4 The locating pins 31 are symmetrically arranged at the center, and the winding drum 11 is provided with a plurality of limiting holes 113 that are compatible with the locating pins 31. The locating pins 31 can be selectively inserted into some of the limiting holes 113 to stagger the handle 32 and the steel bar 21. Specifically, the number of the locating pins 31 is at least two. When in use, the two locating pins 31 are respectively inserted into the corresponding limiting holes 113. At this time, the handle 32 is perpendicular to the steel bar 21. When the positions of the handle 32 and the steel bar 21 conflict during the winding process, the rotating member 3 can be pulled out, and the locking member can be rotated and the locating pin 31 can be inserted into the replacement hole to continue to drive the winding drum 11 to rotate; or when the locking member drives the winding drum 11 to rotate 180 degrees, the handle 32 conflicts with the ground and cannot continue to rotate, the rotating member 3 is pulled out, and the handle 32 is rotated in the opposite direction by 90 degrees or 180 degrees and then inserted into the limiting hole 113 again, and the winding drum 11 can be driven to rotate again by turning the handle. The operation is simple and quick, and continuous winding operation is realized.

[0048] In a specific embodiment, Figure 5 As shown, five positioning pins 31 are provided at one end of the rotating member 3, wherein four positioning pins 31 are centrally symmetrically arranged around a positioning pin 31 located in the center. Such a design enables the five positioning pins 31 to still be accurately aligned with the limiting holes 113 on the winding disk 11 respectively when the rotating member 3 rotates 90 degrees or 180 degrees in the forward or reverse direction, thereby realizing the continuous winding operation.

[0049] The above-mentioned winding drum 11 includes a well grid frame 112, which includes a plurality of parallel horizontal bars and a plurality of parallel vertical bars. The horizontal bars and the vertical bars are staggered and connected to form limiting holes 113; the limiting holes 113 are also centrally symmetrical, so that the rotating member 3 can still align with different limiting holes 113 when rotating forward or reverse at a set angle, thereby realizing hole replacement insertion and continuous operation.

[0050] Furthermore, the winding drum 11 also includes an arcuate edge 114, which is circumferentially spaced apart on the grid frame 112, and an opening of a fixed groove 111 is formed between adjacent arcuate edges 114. By setting the arcuate edge 114, the outer contour of the overall winding drum 11 presents a circular structure with an opening, which facilitates the shaping and rotational winding of the steel mesh 2.

[0051] Furthermore, the fixing grooves 111 are evenly arranged along the circumference of the winding drum 11, the depth of the fixing grooves 111 is adapted to the diameter of the steel bars 21, and the circumference of the arc-shaped edges 114 between the fixing grooves 111 is the same as the spacing between the steel bars 21, so that when the winding starts, the four steel bars 21 can accurately enter the corresponding fixing grooves 111 respectively, thereby significantly improving the shaping effect of the winding drum 11 on the steel mesh 2, ensuring that the steel mesh 2 can remain neat and flat during the winding process, and effectively preventing the steel mesh 2 from being scattered and deformed during the winding process.

[0052] The winding reel 11 in the present application can be designed in different forms according to the needs. Figure 6-Figure 7 Two types of winding reels 11 that can be adapted to the rotating member 3 having five positioning pins 31 arranged in a centrally symmetrical manner are disclosed; Figure 6 As shown, the cross frame of the winding drum 11 includes two horizontal bars and two longitudinal bars, the horizontal bars and the longitudinal bars are vertically connected, and an arc edge 114 is correspondingly arranged at each vertical angle, so that the horizontal bars, the longitudinal bars and the arc edge 114 surround a limiting hole 113 adapted to the positioning pin 31; at the same time, a connecting rod is arranged between adjacent horizontal bars and adjacent longitudinal bars, so that the opening depth of the fixing groove 111 meets the requirement of embedding the steel bar 21; Figure 7 As shown, the well grid 112 of the winding drum 11 includes three horizontal bars and three vertical bars, the horizontal bars and the vertical bars are vertically connected, the two horizontal bars in the middle and the two vertical bars in the middle form two fixed grooves 111 respectively, and a connecting rod is provided to limit the opening depth of the fixed groove 111; the horizontal bars and the vertical bars surround a plurality of limiting holes 113 adapted to the positioning pins 31, which makes it easier to insert the rotating member 3 into the replacement hole after rotation.

[0053] Furthermore, the winding drum 11, the central connecting rod 12 and the rotating member 3 in the present application are all made of steel bars 21, which can be made of steel bar 21 surplus or steel bar 21 waste commonly found on construction sites, and the cost is low.

[0054] A method for rolling up a surface steel bar 21, Figure 8-Figure 10As shown, the above-mentioned surface layer steel bar 21 winding device is used, which specifically includes the following steps:

[0055] S1, arranging the steel bars 21 according to the set intervals;

[0056] Specifically, the surface steel bars 21 can be divided into several groups according to the size of the laying range of the surface steel bars 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 bars 21 are placed on a fixed plane to ensure that the distance between the steel bars 21 is consistent with the design;

[0057] S2, using a binding member 22 to connect a plurality of steel bars 21 together to form a steel mesh 2;

[0058] In the present application, steel wires are used as binding members 22 to bind the same group of steel bars 21. When the length of the steel bars 21 is long, several steel wires are evenly arranged along the length direction to ensure that the binding is firm;

[0059] S3, placing at least two surface layer steel bar 21 retracting devices on the steel bar 21 at one end of the steel mesh 2, tying the end of the binding member 22 to the surface layer steel bar 21 retracting device, so that the steel bar 21 is embedded in the fixed groove of the retracting disk 11;

[0060] Specifically, a steel bar 21 at one end of the steel mesh 2 is selected as the starting position of the winding operation, so that the steel bar 21 is embedded in the fixed grooves of several winding drums 11; at least two surface steel bar 21 winding devices are respectively arranged near the end parts of the steel bar 21, and several other surface steel bar 21 winding devices can be arranged between the two according to the length of the steel bar 21.

[0061] S4, insert the positioning pin of the rotating member 3 into the limiting hole 113 of the winding disk 11, and turn the handle 32 toward the other end of the steel mesh 2;

[0062] Specifically, each rotating member 3 is operated by one worker to ensure that the plurality of winding reels 11 rotate synchronously, so as to avoid the steel bars 21 being twisted due to inconsistent winding progress of different parts of the steel mesh 2 .

[0063] When the handle 32 of the rotating member 3 is rotated to an angle that is inconvenient to operate, the rotating member 3 is removed and inserted into the limiting hole 113 in another direction that is convenient for operation, so as to drive the winding disk 11 to rotate continuously until the steel mesh 2 is completely wound around the surface steel bar 21 winding device;

[0064] S5, transporting the rolled steel mesh 2 to the construction site, and laying the steel mesh 2 at a preset position by rotating the rotating member 3 in the reverse direction.
