As shown in the figure, the reinforcing bar positioning and laying auxiliary device comprises a barrel 1, a main shaft 2, a handle 3, a color supply mechanism 4 and a plurality of marking mechanisms 5. Among them, the inside of the barrel 1 is hollow, and the barrel 1 comprises a barrel body and two side walls. The barrel body is in a cylindrical shape, and the two side walls are respectively arranged at the two ends of the barrel body to block the two ends of the barrel body. Thus, the two side walls of the barrel 1 form the two ends of the barrel 1.

[0027] The main shaft 2 extends along the length direction of the barrel 1 and is transversely arranged in the barrel 1. Specifically, the main shaft 2 is arranged in the barrel 1, and the main shaft 2 is transversely arranged between the two side walls of the barrel 1.

[0028] One end of the main shaft 2 extends to the outside of the barrel 1, i.e. one end of the main shaft 2 penetrates one of the side walls of the barrel 1, and this end of the main shaft 2 is connected with the handle 3. Specifically, the main shaft 2 is fixedly connected with the handle 3, preferably by welding.

[0029] The outer wall surface of the two side walls of the barrel 1 is provided with a scale, and the scales on the two side walls of the barrel 1 are uniform.

Specifically, the reinforcing bar spacing is generally required to be 100mm, 150mm or 200mm, and the scale is three, each scale is in the form of a ring, and each scale has the center of the side wall of the barrel 1 as the center. The three scales are set for spacing of 100mm, 150mm and 200mm, respectively.

[0030] The barrel body of 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 marking mechanisms 5 is the same as the number of penetration openings. 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 barrel 1, and the color supply mechanism 4 is connected with each marking mechanism 5, and the color supply mechanism 4 is used for providing dye for each marking mechanism 5, and each marking mechanism 5 is used for positioning and laying wire to make the dye coated on the object to be marked, and the wire is installed according to the color coated on the object to be marked.

[0032] Preferably, the outer wall of the barrel body of the barrel 1 is provided with an anti-skid layer 10. Specifically, the anti-skid layer 10 is arranged on the barrel body of the barrel 1 except the positions of the through holes. The anti-skid layer 10 can be made of rubber or other structures, and the embodiment does not make any limitation on this.

[0033] As can be seen, in the embodiment, the barrel body of the barrel 1 is provided with a plurality of through holes according to the scale, each marking mechanism 5 is arranged in the barrel 1 and corresponds to each through hole, and the color supply mechanism 4 provides dye for each marking mechanism 5. In this way, each marking mechanism 5 can position and lay wire according to the scale, which saves time and effort, and does not need to use a marking pen and a large ruler to position and lay wire as in the prior art, greatly improves the construction efficiency, speeds up the construction progress, solves the problem of time-consuming and labor-intensive and affecting the construction progress in the prior art, and ensures the accuracy of the positioning and laying of the wire, thereby ensuring the construction quality.

[0034] Referring to Figures 1 to 9 In the above embodiment, the outer circumferential wall of each of the two side walls of the barrel 1 is provided with a notch 6 corresponding to each through hole. Specifically, the through hole is arranged on the barrel body of the barrel 1. The outer circumferential wall of each of the two side walls of the barrel 1 is provided with a plurality of notches 6, and each notch 6 corresponds to each through hole in each side wall of the barrel 1. The position of each notch 6 corresponds to the position of the corresponding through hole, and each notch 6 is recessed towards the center of the side wall of the barrel 1. The opening of each notch 6 is connected with the corresponding through hole. The positions of the notches 6 on the two side walls of the barrel 1 correspond to each other, and the corresponding notches 6 on the two side walls of the barrel 1 are connected with the corresponding through holes to form marking channels, and the marking channels are a plurality of marking channels.

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

[0036] Referring to Figures 1 to 9In the above embodiment, each marking mechanism 5 comprises a marking shaft 51 and a belt 52. The marking shaft 51 is arranged horizontally between the two side walls of the barrel 1, and the two ends of the marking shaft 51 are respectively arranged in the corresponding notches 6 of the two side walls of the barrel 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 barrel 1, and each end of the marking shaft 51 is arranged in the corresponding notch 6 of the corresponding side wall of the barrel 1.

[0037] The belt 52 is arranged around the marking shaft 51 and the main shaft 2, and the belt 52 is connected to the color supply mechanism 4, which provides the belt 52 with dye. In this way, the dyed belt 52 can apply the dye to the object to be marked, so as to achieve positioning and laying of the reinforcing steel bars.

[0038] Preferably, a plurality of annular accommodating grooves 21 are arranged along the length direction of the main shaft 2, and specifically, the accommodating grooves 21 are uniformly arranged along the length direction of the main shaft 2. The number of the marking mechanisms 5 is the same as the number of the accommodating grooves 21, and the belt 52 in each marking mechanism 5 corresponds to each accommodating groove 21, and each belt 52 is rotatably arranged in the corresponding accommodating groove 21, and specifically, the belt 52 is arranged around the bottom surface of the accommodating groove 21.

[0039] Preferably, the bottom surface of each accommodating groove 21 in contact with the corresponding belt 52 is provided with an anti-skid structure, and specifically, the bottom surface of each accommodating groove 21 is provided with an anti-skid structure to increase the friction between the belt 52 and the accommodating groove 21. In specific implementation, the anti-skid structure can be a friction surface with a predetermined friction degree, or a plurality of anti-skid protrusions can be arranged on the bottom surface of each accommodating groove 21, and of course, the anti-skid structure can also be other structures, which are not limited in the present embodiment.

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

[0041] Each notch 6 of each side wall of the barrel 1 is provided with a marking position and a hidden position, and the marking shaft 51 is movably arranged in the marking position and the hidden position, that is, the marking shaft 51 is selectively arranged in the marking position or the hidden position. When the marking shaft 51 is arranged in the marking position, the belt 52 is dyed from the through hole to the laying position, that is, the belt 52 is in contact with the object to be marked from the through hole, and then the belt 52 is dyed and applied to the object to be marked. When the marking shaft 51 is arranged in the hidden position, the belt 52 is not dyed, that is, the belt 52 cannot be in contact with the object to be marked, so as to not apply dye to the object to be marked.

[0042] The outer circumferential wall of each side wall of the barrel 1 is provided with a groove 61 at each notch 6, and the groove 61 is recessed towards the center of the side wall of the barrel 1. One side wall of the groove 61 is provided with a V-shaped groove 62, and the opening of the V-shaped groove 62 is towards the outer circumferential wall of the side wall of the barrel 1. The V-shaped groove 62 is arranged adjacent to the groove 61, 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 barrel 1 is the same. At each notch 6, the groove 61 is provided on the outer circumferential wall of the side wall of the barrel 1 and is recessed towards the center of the side wall. The groove 61 and the V-shaped groove 62 are arranged adjacent to each other and are 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 in the shape of “L”. The bottom of the V-shaped groove 62 is closer to the center of the side wall of the barrel 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 in the shape of “√”. The shorter inclined side of the “√” shape is connected to the horizontal bottom wall of the “L” shape of the groove 61. In this way, the groove 61 and the V-shaped groove 62 connected to each other form the notch 6.

[0044] The bottom wall of the groove 61 is flat, and the flat bottom wall forms a marking position. The bottom of the V-shaped groove 62 is in the shape of “V”, 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 barrel 1. However, the opening 11 of the groove 61 is provided in an open manner, and the opening 11 of the groove 61 is connected to the through hole. Specifically, the V-shaped groove 61 is excavated from the side wall of the groove 61. Therefore, the opening of the V-shaped groove 62 is blocked by the outer circumferential wall of the side wall of the barrel 1, so that the space between the V-shaped groove 62 and the outer circumferential wall of the side wall of the barrel 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 barrel 1, so that the opening 11 of the groove 61 corresponds to and is connected to the through hole.

[0046] The marking shaft 51 is selectively arranged on the bottom wall of the groove 61 or in the “V” shaped bottom of the V-shaped groove 62. Specifically, the center of each end of the marking shaft 51 is provided with a protrusion 8, and the two protrusions 8 are arranged in the marking position or the hidden position at the same time. More specifically, the two protrusions 8 are arranged at the two ends of the marking shaft 51 respectively, each protrusion 8 is in the shape of a cylinder, 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 arranged in the corresponding notches 6 on the two side walls of the barrel 1 respectively, and the two protrusions 8 are arranged 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 through hole, specifically, the protruding portions 8 of the two ends of the marking shaft 51 are placed on the flat bottom wall of the groove 61, but the circumferential outer wall of the marking shaft 51 protrudes from the outside of the through hole, so the belt 52 wound around the marking shaft 51 also protrudes from the outside of the through hole 1, and the belt 52 can contact the object to be marked from the through hole to dye the object to be marked.

[0048] Since the bottom of the V-shaped groove 62 is closer to the center of the barrel 1 than the bottom of the groove 61, and the opening of the V-shaped groove 62 is shielded by the outer circumferential wall of the side wall of the barrel 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 barrel 1, and since the barrel body of the barrel 1 matches the outer circumferential wall of the side wall of the barrel 1, the circumferential outer wall of the marking shaft 51 is completely below the barrel body, and the belt 52 is also below the barrel body of the barrel 1, so that when the marking shaft 51 is in the hidden position, the belt 52 cannot contact the object to be marked, and the belt 52 cannot 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 through hole, where 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 through hole, so as to avoid the marking shaft 51 from being separated from the barrel 1 at the through hole.

[0050] When the protruding portion 8 is placed on the bottom wall of the groove 61, the depth of the groove 61 should be able to make part of the marking shaft 51 protrude from the through hole to the outside of the barrel 1, and the depth of the groove 61 can be determined according to actual conditions, which is not limited in the embodiment.

[0051] When the protruding portion 8 is placed in the "V" shaped bottom of the V-shaped groove 62, the size between the bottom of the V-shaped groove 62 and the outer circumferential wall of the side wall of the barrel 1 at the opening of the V-shaped groove is greater than the outer diameter of the marking shaft 51, that is, the size of the hidden space is greater than the outer diameter of the protruding portion 8 and the outer diameter of the marking shaft 51, so that the protruding portion 8 can be placed in the hidden space and the marking shaft 51 can be completely placed in the barrel body. That is, the barrel body of the barrel 1 is only open at the through hole, but closed at the opening of the V-shaped groove 62, so when the protruding portion 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 barrel body, and the through hole is exposed.

[0052] Referring to Figure 8 and Figure 9The color supply mechanism 4 includes a color supply cylinder 41 and a sponge. The color supply cylinder 41 is horizontally positioned between the two side walls of the cylinder body 1 and is rotatably fitted onto the outside of the main shaft 2. Specifically, the color supply cylinder 41 is parallel to the main shaft 2, and its two ends correspond one-to-one with the two side walls of the cylinder body 1. Each end of the color supply cylinder 41 is fixedly connected to the corresponding side wall of the cylinder body 1, so the rotation of the cylinder body 1 drives the rotation of the color supply cylinder 41. The interior of the color supply cylinder 41 is hollow, and both ends of the color supply cylinder 41 are closed. The inner wall of the color supply cylinder 41 and the outer wall of the main shaft 2 have a certain gap to form an annular space. The color supply cylinder 41 is rotatably connected to the main shaft 2. Thus, when the main shaft 2 and the handle 3 are relatively fixed, the main shaft 2 remains stationary, while the color supply cylinder 41 rotates together with the cylinder body 1.

[0053] The inside of the ink supply cylinder 41 is used to hold ink. The side wall of the ink supply cylinder 41 has a sliding opening corresponding to each belt 52. Each sliding opening is used for the corresponding belt 52 to slide through.

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

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

[0056] Combined with appendix Figure 1 To be continued Figure 9 The process of using the rebar positioning and marking auxiliary device is described below: Taking the template or concrete surface as an example, according to the rebar spacing requirements in the construction drawings and the scales on the outer walls of the two side walls of the cylinder 1, a suitable insertion port is selected. The marking shaft 51 is moved to the marking position within the notch 6. At this time, part of the belt 52 protrudes outward from the insertion port, allowing it to contact the template or concrete surface. However, the marking shafts 51 at other insertion ports that do not meet the rebar spacing requirements remain hidden within the notch 6. When the worker pushes the handle 3, which remains stationary relative to the main shaft 2, the cylinder 1 rotates, causing the marking shaft 51 at the marking position to rotate, which in turn causes the belt 52 on the marking shaft 51 to rotate. The belt 52 passes through the interior of the ink supply cylinder 41, where it is coated with ink by the ink-absorbing sponge. When the ink-coated belt 52 contacts the template or concrete surface, it leaves a mark. Workers can then place and tie the rebars according to these marks, thus achieving rebar positioning and marking.

[0057] In conclusion, in the embodiment, the barrel body of the barrel 1 is provided with a plurality of through holes according to the scale, each marking mechanism 5 is arranged in the barrel 1 and is arranged at each through hole one by one, the color mechanism 4 provides dye for each marking mechanism 5, so that each marking mechanism 5 can position and lay out the reinforcing steel according to the scale, which saves time and effort, and the marking pen and large ruler do not need to be used for positioning and laying out, the construction efficiency is greatly improved, the construction progress is accelerated, and the construction quality is ensured.
