Among them, the interior of the cylinder 1 is hollow, and the cylinder 1 includes: a cylinder body and two side walls, the cylinder body is cylindrical, and the two side walls are respectively arranged at the two ends of the cylinder body to block the two ends of the cylinder body, and the two side walls of the cylinder body 1 form the two ends of the cylinder body 1.

[0027] The main shaft 2 extends along the length direction of the cylinder 1, and the main shaft 2 is rotatably disposed transversely in the cylinder 1. Specifically, the main shaft 2 is placed in the cylinder 1, and the main shaft 2 is transversely disposed between the two side walls of the cylinder 1, and the two ends of the main shaft 2 correspond to the two side walls of the cylinder 1 one by one, and each end of the main shaft 2 is perpendicular to the corresponding side wall of the cylinder 1 and is rotatably connected.

Specifically, the main shaft 2 and the handle 3 are fixedly connected, preferably welded.

[0029] The outer wall surfaces of the two side walls of the cylinder 1 are provided with scales, and the scales on the two side walls of the cylinder 1 are unified. The scales on each side wall of the cylinder 1 can be set according to the steel bar spacing. Specifically, the steel bar spacing requirements are generally 100mm, 150mm, and 200mm, then there are three scales, each of which is in a circular shape, and each scale is centered on the center of the side wall of the cylinder 1. The three scales are set at intervals of 100mm, 150mm, and 200mm respectively.

[0030] The barrel 1 is provided with a plurality of penetration openings according to the scale. Each marking mechanism 5 is arranged in the barrel 1, and the number of the marking mechanisms 5 is the same as the number of the penetration openings, and each marking mechanism 5 is arranged at each penetration opening in a one-to-one correspondence.

[0031] The color supply mechanism 4 is arranged in the cylinder 1, and is connected to each marking mechanism 5. The color supply mechanism 4 is used to provide dye to each marking mechanism 5. Each marking mechanism 5 positions and lays out the steel bars so that the dye is coated on the object to be marked, and the steel bars are installed according to the color on the object to be marked.

[0032] Preferably, an anti-skid layer 10 is provided on the outer wall of the barrel of the barrel 1. Specifically, the anti-skid layer 10 is provided on the barrel of the barrel 1 and other positions except the penetration openings. The anti-skid layer 10 can be made of rubber or other structures, and this embodiment does not impose any restrictions on this.

[0033] It can be seen that in the present embodiment, the barrel of the cylinder 1 is provided with a plurality of insertion openings according to the scale, each marking mechanism 5 is placed in the cylinder 1 and is arranged one by one at each of the insertion openings, and the color supply mechanism 4 provides dye for each marking mechanism 5, so that each marking mechanism 5 can position and lay out the steel bars according to the scale, saving time and effort, and there is no need to use a marking pen and a large ruler for positioning and laying out as in the prior art, which greatly improves the construction efficiency, speeds up the construction progress, and solves the problem that the steel bar positioning and laying out method in the prior art is time-consuming and labor-intensive and affects the construction progress, and the device can ensure the accuracy of the steel bar positioning and laying out, thereby ensuring the construction quality.

[0034] See also Figures 1 to 9 In the above embodiment, notches 6 are provided on the outer circumferential walls of the two side walls of the cylinder 1 at positions corresponding to each penetration opening, and each notch 6 is connected to the corresponding penetration opening. Specifically, the penetration opening is provided on the cylinder body of the cylinder 1. Multiple notches 6 are provided on the outer circumferential walls of each of the two side walls of the cylinder 1. In each side wall of the cylinder 1, each notch 6 corresponds to each penetration opening one by one, and the position of each notch 6 corresponds to the position of the corresponding penetration opening, and each notch 6 is recessed toward the center of the side wall of the cylinder 1, and the opening of each notch 6 is connected to the corresponding penetration opening. The positions of the notches 6 on the two side walls of the cylinder 1 correspond one by one, and the corresponding notches 6 on the two side walls of the cylinder 1 are connected to the corresponding penetration openings to form a marking channel, and there are multiple marking channels.

[0035] Each marking mechanism 5 corresponds to each marking channel one by one, and each marking mechanism 5 is arranged in the corresponding marking channel.

[0036] See also Figures 1 to 9 In the above embodiment, each marking mechanism 5 includes: a marking shaft 51 and a belt 52. The marking shaft 51 is horizontally arranged between the two side walls of the cylinder 1, and the two ends of the marking shaft 51 are respectively placed in the corresponding notches 6 of the two side walls of the cylinder 1. Specifically, the marking shaft 51 is parallel to the main shaft 2, and the two ends of the marking shaft 51 correspond to the two side walls of the cylinder 1 one by one, and each end of the marking shaft 51 is placed in the corresponding notch 6 of the corresponding side wall of the cylinder 1.

[0037] The belt 52 is wound around the marking shaft 51 and the main shaft 2, and the belt 52 is connected to the color supply mechanism 4, which provides dye for the belt 52, so that the dyed belt 52 can apply the dye to the object to be marked to achieve the positioning and laying out of the steel bars.

[0038] Preferably, the main shaft 2 is provided with a plurality of annular receiving grooves 21 at intervals along its length direction. Specifically, each receiving groove 21 is evenly provided along the length direction of the main shaft 2. The number of the marking mechanisms 5 is the same as the number of the receiving grooves 21. The belts 52 in each marking mechanism 5 correspond to each receiving groove 21 one by one. Each belt 52 can be rotatably wound in the corresponding receiving groove 21. Specifically, the belt 52 is wound around the bottom surface of the receiving groove 21.

[0039] Preferably, the bottom surface of each receiving groove 21 in contact with the corresponding belt 52 is provided with an anti-skid structure. Specifically, the bottom surface of each receiving groove 21 is provided with an anti-skid structure to increase the friction between the belt 52 and the receiving groove 21. In specific implementation, the anti-skid structure can be a friction surface with a preset friction degree set on the bottom surface of the receiving groove 21, or a plurality of anti-skid protrusions can be set on the bottom surface of each receiving groove 21. Of course, the anti-skid structure can also be other structures, and this embodiment does not impose any limitation on this.

[0040] The two opposite side surfaces of each accommodating groove 21 are both smooth, so that when the marking shaft 51 is adjusted to different spacings, the belt 52 will not fall off the main shaft 2.

[0041] Each notch 6 of each side wall of the cylinder 1 is provided with a marking position and a hidden position, and the marking shaft 51 is movably placed in the marking position and the hidden position, that is, the marking shaft 51 can be selectively placed in the marking position or the hidden position. When the marking shaft 51 is placed in the marking position, the belt 52 dyes the line-releasing position from the insertion opening, that is, the belt 52 contacts the object to be marked from the insertion opening, and the belt 52 is stained with the dye and coated on the object to be marked; when the marking shaft 51 is placed in the hidden position, the belt 52 is no longer dyed, that is, the belt 52 cannot contact the object to be marked, and cannot be coated and dyed on the object to be marked.

[0042] Each side wall of the cylinder 1 is provided with a groove 61 on the outer circumferential wall at each notch 6, and the groove is recessed toward the center of the side wall of the cylinder 1. One of the side walls of the groove 61 is provided with a V-shaped groove 62, and the opening of the V-shaped groove 6 faces the outer circumferential wall of the side wall of the cylinder 1. The V-shaped groove 62 and the groove 61 are arranged side by side and adjacent to each other, and the groove 61 and the V-shaped groove 62 are connected to form the notch 6.

[0043] Specifically, the structure of each notch 6 on each side wall of the cylinder 1 is the same. At each notch 6, a groove 61 is opened on the outer circumferential wall of the side wall of the cylinder 1 and is recessed toward the center of the side wall. The groove 61 and the V-shaped groove 62 are adjacently arranged and connected. When connected, the vertical side wall of the groove 61 adjacent to the V-shaped groove 62 is removed, so that the cross section of the groove 61 is "L"-shaped, and the bottom of the V-shaped groove 62 is closer to the center of the side wall of the cylinder 1 than the bottom of the groove 61. In addition, a part of the inclined side wall of the V-shaped groove 62 adjacent to the groove 61 is removed, so that the cross section of the V-shaped groove 62 is "√"-shaped, and the shorter hypotenuse in the "√" shape is connected to the horizontal bottom wall of the "L" shape of the groove 61. In this way, the connected groove 61 and the V-shaped groove 62 form a notch 6.

[0044] The bottom wall of the groove 61 is in a straight state, and the straight bottom wall forms a marking position. The bottom of the V-shaped groove 62 is in a "V" shape, and the bottom of the "V" shape forms a hidden position.

[0045] The opening 11 of the V-shaped groove 62 is not open, but is blocked by the outer circumferential wall of the side wall of the cylinder 1. However, the opening 11 of the groove 61 is open, and the opening 11 of the groove 61 is connected to the penetration opening. Specifically, the V-shaped groove 61 is dug from the side wall of the groove 61, and the opening of the V-shaped groove 62 is blocked by the outer circumferential wall of the side wall of the cylinder 1, so that the space between the V-shaped groove 62 and the outer circumferential wall of the side wall of the cylinder 1 forms a hidden space. The opening 11 of the groove 61 is not blocked by the outer circumferential wall of the side wall of the cylinder 1, and the opening 11 of the groove 61 corresponds to and is connected to the penetration opening.

[0046] The marking shaft 51 can be selectively placed on the bottom wall of the groove 61 or in the "V"-shaped bottom of the V-shaped groove 62. Specifically, the centers of the two ends of the marking shaft 51 are provided with protrusions 8 extending outward, and the two protrusions 8 are placed in the marking position or the hidden position at the same time. More specifically, there are two protrusions 8, which are respectively placed at the two ends of the marking shaft 51. Each protrusion 8 is cylindrical, and the center of each protrusion 8 corresponds to the center of the marking shaft 51. Each protrusion 8 is fixed to the marking shaft 51, and the outer diameter of each protrusion 8 is smaller than the outer diameter of the marking shaft 51. The two protrusions 8 are respectively placed in the corresponding notches 6 on the two side walls of the cylinder 1, and the two protrusions 8 are placed in the marking position or the hidden position in the corresponding notches 6 at the same time.

[0047] When the marking shaft 51 is placed in the marking position, part of the marking shaft 51 protrudes from the insertion opening. Specifically, the raised parts 8 at the two ends of the marking shaft 51 are placed on the flat bottom wall of the groove 61. However, the circumferential outer wall part of the marking shaft 51 protrudes from the outside of the insertion opening. In this way, the belt 52 wound on the marking shaft 51 also protrudes from the outside of the insertion opening 1. The belt 52 can contact the object to be marked from the insertion opening and then dye the object to be marked.

[0048] Since the bottom of the V-groove 62 is closer to the center of the disk body 1 than the bottom of the groove 61, and the opening of the V-groove 62 is blocked by the outer circumferential wall of the side wall of the cylinder 1, when the marking shaft 51 is placed in the hidden position, the circumferential outer wall of the marking shaft 51 is completely below the outer circumferential wall of the side wall of the cylinder 1. Since the barrel of the cylinder 1 matches the outer circumferential wall of the side wall of the cylinder 1, the circumferential outer wall of the marking shaft 51 is completely below the barrel, and the belt 52 is also placed below the barrel of the cylinder 1, so that when the marking shaft 51 is in the hidden position, the belt 52 will not contact the object to be marked, and the belt 52 will not dye the object to be marked.

[0049] Specifically, the circumferential distance of the opening of the groove 61 is equal to the circumferential distance of the penetration opening, wherein the circumferential distance is the distance in the circumferential direction. The outer diameter of the marking shaft 51 is greater than the circumferential distance of the penetration opening to prevent the marking shaft 51 from escaping from the barrel 1 from the penetration opening.

[0050] When the protrusion 8 is placed on the bottom wall of the groove 61, the depth of the groove 61 should be able to allow part of the marking axis 51 to protrude from the penetration opening to the outside of the cylinder 1. The specific value of the depth of the groove 61 can be determined based on actual conditions, and this embodiment does not impose any restrictions on this.

[0051] When the protrusion 8 is placed in the "V"-shaped bottom of the V-shaped groove 62, the dimension between the bottom of the V-shaped groove 62 and the outer circumferential wall of the side wall of the cylinder 1 at the opening of the V-shaped groove is larger than the outer diameter of the marking shaft 51, that is, the dimension of the hidden space is larger than the outer diameter of the protrusion 8 and larger than the outer diameter of the marking shaft 51, so that the protrusion 8 can be placed in the hidden space and the marking shaft 51 can be completely placed inside the cylinder body. In other words, the cylinder body of the cylinder body 1 is only open at the penetration opening, but is closed at the opening of the V-shaped groove 62, so when the protrusion 8 is placed in the "V"-shaped bottom of the V-shaped groove 62, the marking shaft 51 should be able to be completely placed below the cylinder body, and the penetration opening is exposed.

[0052] See also Figure 8 and Fig. 9The color supply mechanism 4 includes: a color supply cylinder 41 and a sponge. The color supply cylinder 41 is horizontally arranged between the two side walls of the cylinder 1, and the color supply cylinder 41 is rotatably sleeved on the outside of the main shaft 2. Specifically, the color supply cylinder 41 is parallel to the main shaft 2, and the two ends of the color supply cylinder 41 correspond to the two side walls of the cylinder 1 one by one. Each end of the color supply cylinder 41 is fixedly connected to the corresponding side wall of the cylinder 1, and the rotation of the cylinder 1 drives the rotation of the color supply cylinder 41. The interior of the color supply cylinder 41 is hollow, and the two ends of the color supply cylinder 41 are closed ends. The color supply cylinder 41 is sleeved on the outside of the main shaft 2, and there is a certain gap between the inner wall of the color supply cylinder 41 and the outer wall of the main shaft 2 to form an annular space. The color supply cylinder 41 is rotatably connected to the main shaft 2, so that the main shaft 2 and the handle 3 are relatively fixed, the main shaft 2 is fixed, and the color supply cylinder 41 rotates with the cylinder 1.

[0053] The interior of the color supply cylinder 41 is used to be loaded with ink, and a sliding opening is opened on the side wall of the color supply cylinder 41 corresponding to each belt 52, and each sliding opening is used for a corresponding belt 52 to be slidably inserted therethrough.

[0054] The sponge is filled inside the color supply cylinder 41 , and the sponge is filled sufficiently to ensure the ink painting effect on the belt 52 .

[0055] It can be seen that in this embodiment, the marking mechanism 5 and the color supply mechanism 4 have simple structures and are easy to implement.

[0056] Combined with Figure 1 To Attachment Fig. 9 The use process of the reinforcement positioning and setting-out auxiliary device is introduced: the process is introduced by taking the template or concrete surface as an example of the object to be marked. According to the reinforcement spacing requirements of the construction drawings, and according to the scales on the outer wall surface of the two side walls of the cylinder 1, the insertion opening that meets the reinforcement spacing requirements is selected, and the marking shaft 51 is moved to the marking position in the notch 6. At this time, part of the belt 52 protrudes outward from the insertion opening, so that the belt 52 can contact the template or concrete surface. However, the marking shaft 51 at the other insertion openings that do not meet the reinforcement spacing requirements is in a hidden position in the notch 6. The staff pushes the handle 3, and the handle 3 and the main shaft 2 are relatively stationary, then the cylinder 1 rotates, and then drives the marking shaft 51 at the marking position to rotate, and then drives the belt 52 on the marking shaft 51 to rotate, and the belt 52 passes through the interior of the color supply cylinder 41, and then the belt 52 is coated with ink by the sponge that absorbs ink in the color supply cylinder 41. The belt 52 coated with ink can leave marks when it contacts the template or concrete surface. The workers can place and tie the reinforcement according to the wear marks, thereby realizing the reinforcement positioning and setting-out.

[0057] In summary, in the present embodiment, the body of the cylinder 1 is provided with a plurality of insertion openings according to the scale, each marking mechanism 5 is placed in the cylinder 1 and is arranged one by one at each of the insertion openings, and the color supply mechanism 4 provides dye for each marking mechanism 5, so that each marking mechanism 5 can position and lay out the steel bars according to the scale, saving time and effort, and there is no need to use a marking pen and a large ruler for positioning and laying out as in the prior art, which greatly improves the construction efficiency and speeds up the construction progress, and the device can ensure the accuracy of the steel bar positioning and laying out, thereby ensuring the construction quality.
