Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and more specifically, to a device for marking the distance between steel bars. Background Technology

[0002] In the complex scenarios of modern building construction, rebar tying is a crucial step for structural safety, and its accuracy and efficiency directly affect the overall quality and progress of the project. In traditional construction, the placement of rebar often relies on manual marking, a step fraught with challenges and limitations. Workers must first use tools such as measuring tapes to measure and mark the placement points of each rebar on the formwork surface, and then connect these points with lines to form a reference line for rebar placement. This process is not only tedious but also highly dependent on the experience and skill level of the operators, thus having many shortcomings.

[0003] First, while the two-person collaborative model improves operational flexibility to some extent, it also increases the complexity of communication and coordination, and the possibility of errors, leading to low construction efficiency. This is especially true in large projects, where the increasing size of formwork and the density of rebar placement make this manual marking method increasingly inadequate. Second, the accuracy of manual marking is difficult to guarantee. Due to limitations in human visual judgment, hand stability, and the ability to read measuring tape, the drawn lines often have some deviation, which not only affects the accuracy of rebar tying but may also pose a potential threat to the structure's load-bearing capacity. Third, the randomness and time-consuming nature of manual marking are also significant issues. Determining each marking point requires multiple measurements and adjustments, consuming considerable time and manpower, and increasing uncertainty during construction. If adjustments to the design or rebar placement are needed, all completed markings may need to be redone, further exacerbating the pressure on the construction schedule. More importantly, the decline in construction quality and delays caused by these problems ultimately translate into increased construction costs. To compensate for the losses caused by insufficient accuracy and inefficiency, companies often need to invest more resources in subsequent repair and rectification work, which not only increases the economic burden but may also damage the company's reputation and competitiveness.

[0004] Therefore, there is an urgent need for a device for marking the distance between reinforcing bars to solve the problems of low efficiency, poor accuracy and high labor costs in the existing technology of reinforcing bar layout relying on manual marking. Utility Model Content

Detailed Implementation

[0033] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0034] In the description of this application, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0035] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0036] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0037] See Figure 1-4 As shown, this embodiment provides a distance marking device for steel bars, including an ink-dispensing roller 100 with an ink outlet 110 on its side wall and ink filling the inside of the ink-dispensing roller 100; two side wheels 200 are provided, which are detachably disposed on both sides of the ink-dispensing roller 100 and are used to drive the ink-dispensing roller 100 to rotate; and an operating lever 300, one end of which is hinged to the side of the side wheel 200 away from the ink-dispensing roller 100 and is used to drive the side wheel 200 to rotate.

[0038] It is understandable that using a distance marking device between rebars for binding can ensure uniform spacing between rebars, improve the quality of rebar binding, and significantly increase work efficiency; it avoids rework caused by uneven rebar spacing, thus avoiding wasted time; the distance marking device between rebars is reusable after manufacture and is easy to use; this utility model's distance marking device between rebars can not only save the marking time of two rebar workers, but also increase the workers' enthusiasm for work.

[0039] In some embodiments of this application, the ink output roller 100 includes a roller body 120 with a hollow internal structure, and the two ends of the roller body 120 are detachably connected to the side wheel 200; a sponge 130 is filled inside the roller body 120 and is used to absorb ink; and a control head 140 is movably disposed on the ink outlet 110.

[0040] It is understandable that when the sponge 130 is placed in the ink delivery roller 100, it can absorb ink. When the ink delivery roller 100 is rolling, the control head 140 located on the outside of the roller body 120 is squeezed by the ground. The control head 140 located on the inside of the roller body 120 will squeeze the sponge 130 inside the roller body 120, causing the ink absorbed in the sponge 130 to be squeezed out and flow out from the ink outlet 110 along the control head 140. The ink delivery roller 100 has a simple structure and can conveniently and accurately control the ink delivery distance of the ink delivery roller 100, making it highly practical.

[0041] In some embodiments of this application, the control head 140 includes an inner block 141 disposed inside the roller body 120. The inner block 141 contacts the sponge 130, and the contact area between the inner block 141 and the sponge 130 is larger than the area of ​​the ink outlet 110. The inner block 141 is used to squeeze the sponge 130. An outer block 142 is connected to the inner block 141 at one end, and the other end of the outer block 142 extends out of the ink outlet 110.

[0042] Understandably, the pressure of the ground on the outer block 142 will cause the inner block 141 to squeeze the sponge 130, thereby causing the ink in the sponge 130 to flow out from the ink outlet 110. The contact area between the inner block 141 and the sponge 130 is larger than the area of ​​the ink outlet 110, which can keep the inner block 141 in the roller body 120 and prevent it from falling out of the ink outlet 110.

[0043] In some embodiments of this application, the side of the side wheel 200 is provided with an ink inlet 210, and a sealing head 220 is detachably provided on the ink inlet 210. The ink inlet 210 is used to fill ink, and the sealing head 220 is used to block the ink inlet 210.

[0044] Understandably, the ink inlet 210 is provided on the side of the side roller 200, so that ink can be filled without removing the roller body 120, which is convenient and practical.

[0045] In some embodiments of this application, the operating lever 300 includes a connector 310 with three connecting ends, two of which are respectively connected to two side wheels 200; and a lever body 320, one end of which is connected to the end of the connector 310 away from the side wheel 200.

[0046] In some embodiments of this application, the connector 310 includes two connecting pieces 311, one end of which is connected to the end of the side wheel 200 away from the ink output roller 100; and a connecting piece 312, which is disposed between the two connecting pieces 311 and located at the end of the two connecting pieces 311 away from the side wheel 200, and is used to connect the two connecting pieces 311.

[0047] It is understandable that one end of the connector 310 is fixed to the operating lever 300, and the other two ends are hinged to the side wheel 200. The operator can control the operating lever 300 to make the side wheel 200 drive the ink roller 100 to roll, thereby achieving fixed distance marking. Preferably, the size of the side wheel 200 can be changed according to the operator's distance requirements, that is, a larger side wheel 200 can be replaced for long distances, which is convenient and practical.

[0048] In some embodiments of this application, the rod 320 is a telescopic rod 320, so that the length of the rod 320 can be changed.

[0049] Understandably, setting the pole 320 as a telescopic pole 320 can accommodate workers of different heights and improve the practicality of the device.

[0050] In some embodiments of this application, a handle 400 is provided at the end of the rod 320 away from the ink output roller 100.

[0051] Understandably, the 400 is designed with a handle for easy hand gripping and operation, making it highly practical.

[0052] The working principle of this utility model is as follows: Open the sealing head 220, pour ink into the ink outlet roller 100, and after completion, install the sealing head 220 on the side wheel 200. Place the ink outlet roller 100 at the position where the line needs to be marked. The operator holds the handle 400 and pushes the operating lever 300. The outer block 142 is squeezed by the ground, which pushes the inner block 141 to squeeze the sponge 130, so that the ink in the sponge 130 flows out from the ink outlet 110, and the marking is completed.

[0053] In summary, using a marking device for rebar spacing to tie rebars can ensure uniform rebar spacing, improve the quality of rebar tying, and significantly increase work efficiency; it avoids rework caused by uneven rebar spacing, thus preventing wasted time; the marking device for rebar spacing is reusable after manufacture and is easy to use; this utility model's marking device for rebar spacing not only saves two rebar workers' marking time but also increases workers' enthusiasm.

[0054] It will be understood by those skilled in the art that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
