Abstract
Description
Technical Field
[0001] This utility model relates to the field of building information modeling technology, and in particular to a tool for collaborative construction of multi-disciplinary pipe networks in basements using BIM. Background Technology
[0002] With the widespread application of Building Information Modeling (BIM) technology in the collaborative construction of multi-disciplinary pipe networks in basements, it is necessary to accurately map the pipe network routes in the BIM model to the construction site before construction to facilitate collaborative work among construction personnel of various disciplines. In this process, marking tools become key equipment for transforming virtual models into actual construction guidelines. Traditional marking tools use chalk to draw lines directly, which has the following problems: Due to the complex ground conditions of basement construction sites, including gravel and uneven surfaces, chalk is prone to breakage due to uneven force during the marking process. This not only affects the construction progress but also increases labor costs due to frequent chalk replacements. In addition, it is difficult to ensure the verticality of the chalk during the marking process, leading to deviations in pipe network positioning, which affects the accuracy of subsequent construction and the overall project quality. Therefore, we have introduced a tool for collaborative construction of multi-disciplinary pipe networks in basements using BIM. Utility Model Content
[0003] The main purpose of this utility model is to provide a tool for collaborative construction of multi-disciplinary pipe networks in basements using BIM, which can effectively solve the problems in the background technology.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0005] A tool for collaborative construction of multi-disciplinary pipe networks in basements using BIM includes a hand-held marking frame. Two rollers are movably installed at the left and right ends of the hand-held marking frame. The outer surfaces of the four rollers are provided with anti-slip textures. A marking device is inserted and fixedly connected to the upper rear part of the hand-held marking frame.
[0006] Preferably, the marking device includes a mounting cylinder, a pressing rod is movably connected to the middle of the upper end of the mounting cylinder, a pressing head is fixedly connected to the upper end of the pressing rod, a rubber pad is fixedly connected to the upper end of the pressing head, a chalk sleeve is fixedly connected to the lower end of the pressing rod, a spring is fixedly connected to the upper end of the chalk sleeve, a fixing ring is fixedly sleeved on the upper part of the outer surface of the chalk sleeve, three T-shaped sliders are fixedly connected to the outer surface of the fixing ring, a marking chalk is movably sleeved inside the chalk sleeve, and three T-shaped grooves are opened on the inner wall of the mounting cylinder.
[0007] By adopting the above technical solution, pressing the pressing head can move the marking chalk inside the chalk sleeve downward to draw lines. After releasing the pressure, the spring automatically returns to its original position, eliminating the need for frequent manual adjustment of the chalk position. The operation is simple and labor-saving, greatly improving the efficiency of marking lines.
[0008] Preferably, the hand-held marking frame includes a frame body, a finger sleeve is fixedly connected to the upper front part of the frame body, a first rubber sleeve is fixedly sleeved inside the finger sleeve, a first finger groove is opened at the upper front part of the frame body, a second finger groove is opened at both the left and right ends of the frame body, a second rubber sleeve is fixedly sleeved in each of the two second finger grooves, and a fixing hole is opened at the upper rear part of the frame body.
[0009] By adopting the above technical solution, the first finger groove and two second finger grooves form a stable grip relationship between the hand and the hand holding the marking frame. When moving the marking frame in the complex basement environment, the construction personnel can better control the direction and force of the marking. In conjunction with the marking device, the accuracy of the lines is ensured, and the marking deviation caused by unstable grip is avoided, thus ensuring the accurate representation of the BIM model pipeline network on the construction site.
[0010] Preferably, the connection between the front end and the upper end of the frame is set as a rounded corner edge, and the first finger groove is set on the rounded corner edge.
[0011] By adopting the above technical solution: the first finger groove is set on the rounded edge, which perfectly fits the natural curvature of the human finger joint, improving the comfort of holding.
[0012] Preferably, the mounting sleeve is fixedly fitted inside the fixing hole.
[0013] Preferably, the upper end of the spring is fixedly connected to the upper inner wall of the mounting cylinder, and the pressing rod is located inside the spring and has a gap with the inner wall of the spring.
[0014] By adopting the above technical solution, when the construction worker releases the pressing head, the elastic restoring force of the spring can quickly pull the pressing rod and the chalk sleeve back to the initial position, so that the marking chalk can be lifted off the ground in time, control the marking length and start and end points, avoid line trailing or repeated marking, and improve marking efficiency and quality.
[0015] Preferably, the portions of the three T-shaped sliders that are away from the center of the chalk sleeve are respectively movably fitted into the corresponding three T-shaped grooves.
[0016] By adopting the above technical solution, the movable sleeve allows the T-shaped slider to have a certain amount of movement space within the T-shaped groove. Combined with the spring structure, it can effectively buffer the impact force caused by uneven ground. When encountering ground bumps or depressions, the T-shaped slider can be finely adjusted within the groove, preventing the marking chalk from breaking due to uneven force, reducing chalk wear, extending chalk life, and saving construction costs.
[0017] Compared with the prior art, the present invention has the following beneficial effects:
[0018] In this invention, the index and middle fingers are slipped into the finger sleeves with their tips resting on the first finger groove, the thumb is placed in the front second finger groove, and the ring and little fingers are placed in the rear second finger groove. The palm rests against the rubber pad on the pressing head. The first and second rubber sleeves provide a comfortable grip. When pushing the tool, four rollers with anti-slip textures create rolling friction with the ground, ensuring the tool moves smoothly in a straight line and avoiding wobbling caused by uneven ground. When drawing lines, the palm presses down on the rubber pad, and the pressing rod moves the chalk sleeve downward. At this time, the spring is compressed, and the three T-shaped sliders slide vertically within the T-shaped grooves, restricting the movement of the chalk sleeve. The direction ensures that the marking chalk is always perpendicular to the ground. Even with slight undulations in the ground, the spring's cushioning and the T-shaped slider's guiding action prevent the chalk from breaking due to sudden changes in force. Continuous pressing and uniformly pushing the tool completes the marking. Releasing the pressure causes the spring to return to its original position, lifting the chalk sleeve and detaching the chalk from the ground, thus stopping the marking process. This not only improves marking efficiency and reduces chalk wear, but also ensures line accuracy through roller guidance and a vertical positioning structure. This allows the pipeline network in the BIM model to be accurately represented on the construction site, providing a reliable guarantee for the collaborative construction of multi-disciplinary pipeline networks in the basement.

[0029] Please see Figure 1-6 This utility model provides a technical solution:
[0030] A tool for collaborative construction of multi-disciplinary pipeline networks in basements using BIM includes a hand-held marking frame 1. Two rollers 2 are movably installed at the left and right ends of the hand-held marking frame 1. The outer surfaces of the four rollers 2 are provided with anti-slip textures 3. A marking device 4 is inserted and fixedly connected to the upper rear part of the hand-held marking frame 1.
[0031] In this embodiment, the marking device 4 includes a mounting cylinder 41. A pressing rod 42 is movably connected to the middle of the upper end of the mounting cylinder 41. A pressing head 43 is fixedly connected to the upper end of the pressing rod 42. A rubber pad 44 is fixedly connected to the upper end of the pressing head 43. A chalk sleeve 45 is fixedly connected to the lower end of the pressing rod 42. A spring 46 is fixedly connected to the upper end of the chalk sleeve 45. A fixing ring 47 is fixedly sleeved on the upper part of the outer surface of the chalk sleeve 45. Three T-shaped sliders 48 are fixedly connected to the outer surface of the fixing ring 47. A marking chalk 49 is movably sleeved inside the chalk sleeve 45. Three T-shaped grooves 491 are opened on the inner wall of the mounting cylinder 41. The hand-held marking frame 1 includes a frame 11. A finger sleeve 12 is fixedly connected to the front of the upper end of the frame 11. A finger sleeve 12 is fixedly sleeved inside the finger sleeve 12. A first rubber sleeve 13 is attached. A first finger groove 14 is opened at the upper front end of the frame 11. A second finger groove 15 is opened at both the left and right ends of the frame 11, and a second rubber sleeve 16 is fixedly fitted in each of the two second finger grooves 15. A fixing hole 17 is opened at the rear upper end of the frame 11, which is open in both the inside and outside. The connection between the front end and the upper end of the frame 11 is set as a rounded edge, and the first finger groove 14 is set on the rounded edge. The mounting cylinder 41 is fixedly fitted in the fixing hole 17. The upper end of the spring 46 is fixedly connected to the upper inner wall of the mounting cylinder 41. The pressing rod 42 is located in the spring 46 and there is a gap between it and the inner wall of the spring 46. The three T-shaped sliders 48 are respectively movably fitted in the three corresponding T-shaped sliding grooves 491, with the part away from the center of the chalk sleeve 45.
[0032] It should be noted that this utility model is a tool for collaborative construction of multi-disciplinary pipe networks in basements using BIM. In use, the marking chalk 49 is inserted into the chalk sleeve 45, the index and middle fingers are inserted into the finger sleeves 12, with the fingertips resting on the first finger groove 14 on the rounded corner. The first rubber sleeve 13 increases the comfort of the index and middle fingers. The thumb is placed in the second rubber sleeve 16 of the second finger groove 15 at the front end of the frame 11. The ring and little fingers are naturally placed in the second finger groove 15 at the rear end of the frame 11. The second rubber sleeve 16 further increases the comfort of the thumb, ring, and little fingers. At this time, the spring 46 is in a naturally extended state, pushing the hand to grip the marking frame 1. The anti-slip texture 3 of the four rollers 2 forms rolling friction with the contact surface to prevent slippage and ensure the smooth movement trajectory. To ensure straightness, apply pressure with your palm facing down. Pressing lever 42 moves chalk sleeve 45 downward, compressing spring 46. T-slider 48 slides vertically within T-groove 491, ensuring chalk 49 contacts the ground vertically and preventing line deviation due to tilting. Continue pressing and pushing the tool at a constant speed, chalk 49 forms a marking line on the ground. Roller 2 rolls smoothly to prevent bouncing from affecting line quality. When a change of direction is needed, slightly rotate frame 11 with thumb as fulcrum, while the other fingers adjust in coordination. All four rollers 2 turn synchronously. After releasing the pressure, the elastic return of spring 46 causes chalk sleeve 45 to rise, chalk 49 disengages from the contact surface, and marking stops. Repeat this process to continuously draw parallel or intersecting pipeline markings.
