Description

Technical Field

[0001] The utility model relates to the technical field of acceptance devices, and in particular to a steel structure construction acceptance device based on BIM technology. Background Art

[0002] BIM, or Building Information Modeling, is a new tool in architecture, engineering, and civil engineering. It describes computer-aided design (CAD) that utilizes 3D graphics and object-oriented design. BIM enables the pre-design of 3D drawings for multi-point layout systems for drainage ditches, allowing for evaluation and production.

[0003] In practice, steel structures require inspection and acceptance to ensure their strength in the future. Currently, these inspections are mostly performed using a square or spirit level, which can only determine whether the verticality between adjacent steel structures meets the requirements. However, complex steel structures often have diverse diagonal bracing mechanisms, which are not perpendicular to adjacent steel structures. Furthermore, complex steel structures must also be inspected for deformation to prevent damage during transportation that could cause stress changes in the steel structure and lead to load-bearing failure.

[0004] Therefore, in order to achieve comprehensive inspection of complex steel structures, we believe that a steel structure construction acceptance device is needed that has diversified inspection methods and can leave traces in time for later processing. Summary of the Invention

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0026] Please refer to Figure 1-6A steel structure construction acceptance device based on BIM technology is consistent with the existing technical device. It includes a fixed plate 1, and a U-shaped fixing frame 10 is provided on the rear side of the fixed plate 1. In practice, the fixed plate 1 can be clamped on the steel structure at a specific position through the U-shaped fixing frame 10. This can facilitate the device to detect steel structures in complex positions.

[0027] At the same time, if Figure 2 As shown, each U-shaped fixing frame 10 has a bolt screwed to its side end. By rotating the bolt to change the length of the bolt embedded in the U-shaped fixing frame 10, the device can adapt to steel structures of different widths and sizes, ensuring that the U-shaped fixing frame 10 can actually fix the entire device.

[0028] Unlike the prior art devices, this device is provided with a positioning plate 4 on the front side of the fixed plate 1, and a bearing II 11 is provided between the positioning plate 4 and the fixed plate 1. In addition, the positioning plate 4 is fixedly connected to the outer ring of the bearing II 11, and the fixed plate 1 is fixedly connected to the inner ring of the bearing II 11. This can utilize the bearing II 11 to realize the rotational connection between the positioning plate 4 and the fixed plate 1, and minimize the friction resistance between the fixed plate 1 and the positioning plate 4.

[0029] At the same time, the device is provided with a follower plate 3 on the front side of the positioning plate 4. The follower plate 3 is slidably connected to the positioning plate 4, and the follower plate 3 performs linear motion relative to the positioning plate 4 along its length direction.

[0030] At this time, by setting the corresponding drawing paper 2 on the front side of the follower plate 3, setting the corresponding drawing pen 12 on the front side of the drawing paper 2, and constraining the drawing pen 12 to be movably connected to the fixed plate 1 through the fixed rod 13, the writing end of the drawing pen 12 is in contact with the drawing paper 2, then in practice, by sliding the follower plate 3 left and right and swinging it up and down, the drawing pen 12 that remains stationary can be used to leave corresponding marks on the drawing paper 2.

[0031] Therefore, in this device, a follower plate 7 is fixedly connected to the right end of the follower plate 3. A handle 8 is fixedly connected to the front end of the follower plate 7, and a roller 16 is rotatably connected to the rear end of the follower plate 7. This allows the operator to hold the handle 8 to make the roller 16 abut the bottom edge of the steel structure. Through the relative movement between the roller 16 and the steel structure, the curvature and flatness of the bottom edge of the steel structure can be reflected on the drawing paper 2 as a clear mark. This method not only facilitates on-site accountability by leaving a mark on the drawing paper 2, but also provides a more intuitive display of the condition of the bottom edge of the steel structure, making it easier to judge its flatness.

[0032] Furthermore, in order to enhance the observation of small deformations and small curvature changes, the present device constrains the drawing paper 2 to be grid paper. At the same time, by utilizing the characteristic of the fixed plate 1 remaining stationary, the horizontal lines on the drawing paper 2 are further constrained to be parallel to the width side of the fixed plate 1, and the vertical lines on the drawing paper 2 are parallel to the length side of the fixed plate 1. This can use the criss-cross lines on the drawing paper 2 to compare the drawn curves, thereby facilitating observation by the operator.

[0033] Furthermore, the device constrains the roller 16 to be rotatably connected to the driven plate 7 via the bearing Ⅰ 9, which can reduce the friction resistance encountered by the roller 16 during rotation and thus reduce friction loss.

[0034] It should be noted that since the driven plate 7 is located on the right side of the follower plate 3, in order to achieve a larger displacement distance of the follower plate 3 and avoid the overall size of the device being too large and causing inconvenience in use, the constraint bearing II 11 of the device is located at the lower end of the right side of the positioning plate 4.

[0035] Therefore, in order to ensure convenience in each use, the device is provided with a corresponding recovery mechanism 5 at the upper left end of the positioning plate 4 to enable the follower plate 3 to have a leftward movement trend relative to the positioning plate 4.

[0036] The draw rope 504 is wound around the outer side of the rope roller 502, and a spring 501 is provided on the inner side of the rope roller 502. The fixed end of the spring 501 is fixedly connected to the bottom shell 505, and the movable end of the spring 501 is fixedly connected to the rope roller 502. At this time, by penetrating a through groove at one end of the bottom shell 505 close to the follower plate 3, the pull rope 504 is constrained to pass through the through groove away from the rope roller 502 and fixedly connected to the follower plate 3, the spring 501 can be used to cooperate with the pull rope 504 to apply a leftward pulling force to the follower plate 3. This can make the follower plate 3 automatically move leftward relative to the positioning plate 4 and reset after the use of the device is completed, thereby reducing the storage size of the device.

[0037] Furthermore, the device constrains the rope roller 502 to be rotatably connected to the bottom shell 505 through the bearing III 503. This, in conjunction with the bearing I9 and the bearing II 11, can minimize the frictional resistance encountered by the user when pulling the follower plate 3, so that the resistance encountered by the operator during actual use is as small as possible, which facilitates use.

[0038] Specifically, in order to realize a convenient connection process between the follower plate 3 and the drawing paper 2, the present device is provided with a spring clip 6 on the front side of the follower plate 3. The two spring clips 6 are symmetrically arranged on the left and right, and the spring clips 6 are in the shape of a dovetail clip. This enables the follower plate 3 to be movably connected to the drawing paper 2 through the spring clip 6.

[0039] Specifically, in order to realize a convenient connection process between the drawing pen 12 and the fixed plate 1 and to ensure that the drawing pen 12 is always in contact with the drawing paper 2 during actual use, the present device is fixedly connected to a limit block 14 at the part of the fixed rod 13 located in front of the follower plate 3, and a front-to-back axial through hole is opened on the limit block 14, and the drawing pen 12 is inserted into the through hole.

[0040] At this time, by opening an internal threaded hole through the lower end of the limit block 14, and screwing a butterfly screw into the threaded hole, it is possible to fix drawing pens 12 of different sizes in the process of constraining the tail of the butterfly bolt 15 to abut against the drawing pen 12, ensuring that the drawing pen 12 is always in contact with the drawing paper 2.

[0041] During actual use, the utility model:

[0042] First, the operator uses a U-shaped fixing frame 10 to fix the device on the steel structure adjacent to the position to be detected. At this time, the projection of the follower plate 3 on the vertical plane and the projection of the positioning plate 4 on the vertical plane overlap the largest area;

[0043] Then, the operator holds the handle 8 and at the same time, places the roller 16 against the lower edge of the steel structure at the corresponding detection position;

[0044] Afterwards, the operator pulls the driven plate 7 to the right using the handle 8, during which the roller 16 is ensured to abut against the steel structure;

[0045] Finally, as the follower plate 3 continues to move rightward, relative friction occurs between the drawing paper 2 and the drawing pen 12, thereby forming a curve consistent with the shape of the steel structure.

[0046] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
