Description

Technical Field

[0001] This utility model relates to the field of building technology, and in particular to an adjustable protective cover for expansion joints and openings. Background Technology

[0002] During the main construction phase of a construction project, construction joints and openings are left in the structure as required by the design drawings. Due to factors such as construction technology, the installation of the finished expansion joint cover plates is relatively delayed, which makes it easy for accidents such as falls from heights and falling objects to occur on site.

[0003] During the main construction phase of a project, temporary protection is needed for construction joints and openings. This is typically achieved using wooden formwork or planks for simple covering to ensure worker safety and prevent falling materials. However, this traditional approach has significant problems: First, wooden formwork usually requires steel nails for fixing, which can damage the building structure and affect the support of the formwork edges, making it unusable and increasing material costs. Second, wooden formwork and planks are prone to displacement, deformation, or even collapse when subjected to worker footsteps or heavy loads, especially at larger construction joints and openings. This greatly increases safety risks on the construction site, potentially leading to falls or other accidents. These problems not only affect construction efficiency and increase rectification time and costs but can also cause serious safety accidents, damaging project progress and the company's reputation.

[0004] Therefore, an adjustable protective cover plate for expansion joints and openings needs to be designed to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an adjustable protective cover for expansion joints and openings.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An adjustable protective cover for expansion joints and openings includes two symmetrically arranged angle iron pieces. The longitudinal section of the angle iron pieces is L-shaped. Threaded rods are fixed on the opposite sidewalls of the two angle iron pieces, and the threads of the two threaded rods are in opposite directions. Sleeves are threaded onto the threaded rods, and two connecting rods are fixedly connected between the two sleeves. A support assembly is provided on both angle iron pieces.

[0008] As a preferred technical solution of this utility model, the support component includes a cover plate and two extension plates. The lower surface of the extension plate is in contact with the top of the angle iron piece, and the longitudinal section of the extension plate has a transverse L-shaped structure. Two bolts are fixed at the edge of the upper surface of the extension plate. The cover plate is located on the two extension plates. Two adjustment ports are opened on the cover plate. The two bolts located on the same extension plate pass through the two adjustment ports respectively. Nuts are threaded on the bolts, and the bottom of the nuts abuts against the upper surface of the cover plate.

[0009] As a preferred embodiment of this utility model, a positioning plate is fixedly connected to the lower surface of the extension plate, and the positioning plate is in contact with the side wall of the angle iron.

[0010] As a preferred technical solution of this utility model, a protective cover is fixedly sleeved on the nut. The protective cover is made of rubber material and has a frustum-shaped structure.

[0011] As a preferred embodiment of this utility model, limiting plates are fixedly connected to the opposite ends of the two threaded rods.

[0012] As a preferred embodiment of this utility model, the connecting rod is provided with anti-slip texture.

[0013] This utility model has the following beneficial effects:

[0014] 1. Improve safety: The design of angle iron parts and threaded rods allows the protective cover to be firmly fixed at construction joints or openings, preventing displacement, deformation or collapse caused by stepping or heavy object pressure. In addition, the use of bolts and nuts, as well as the limiting effect of positioning plates, ensures a stable connection between the cover plate and the extension plate, reducing safety hazards and improving the level of safe and standardized construction.

[0015] 2. Improved flexibility and adaptability: The reverse thread design of the threaded rod and sleeve allows the two angle iron pieces to move towards or away from each other. The extension plate can adjust the covering area of ​​the cover plate, so it can be flexibly adjusted according to construction joints or openings of different sizes. This makes the device suitable for openings and construction joints of various sizes, improving the versatility and practicality of the device, and making it suitable for a variety of construction scenarios.

[0016] 3. Improved construction efficiency: The device has a simple structure and can be installed and adjusted with simple screwing operations, which greatly reduces installation time and labor costs. The device can also be easily disassembled and reinstalled in other locations, reducing material costs, improving resource utilization, and reducing the investment in safety measures. This also reduces the rectification time required due to the failure of protective measures and speeds up the construction progress. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-3 An adjustable protective cover for expansion joints and openings includes two symmetrically arranged angle iron pieces 1. The longitudinal section of the angle iron pieces 1 is L-shaped. Threaded rods 2 are fixed to the opposite sidewalls of the two angle iron pieces 1. The threaded rods 2 are fixed to the angle iron pieces 1 by welding, and the threads of the two threaded rods 2 are opposite in direction. This allows the two angle iron pieces 1 to move towards or away from each other during adjustment. Sleeves 3 are threaded onto the threaded rods 2. Limiting plates 12 are fixedly connected to the opposite ends of the two threaded rods 2 to prevent the sleeves 3 from detaching from the threaded rods 2 and to ensure the stability of the device structure. Two connecting rods 4 are fixedly connected between the two sleeves 3. The two connecting rods 4 are symmetrically arranged and have anti-slip textures, making it convenient for workers to adjust the position of the angle iron pieces 1 by turning the connecting rods 4.

[0023] Reference Figure 1 and Figure 3Both angle iron pieces 1 are equipped with a common support assembly, which includes a cover plate 6 and two extension plates 5. The lower surface of the extension plate 5 is in contact with the top of the angle iron piece 1, and the longitudinal section of the extension plate 5 is a transverse L-shaped structure. A positioning plate 10 is fixedly connected to the lower surface of the extension plate 5, and the positioning plate 10 is in contact with the side wall of the angle iron piece 1. In this way, the space formed between the positioning plate 10 and the extension plate 5 can be adapted to the top and side wall of the angle iron piece 1, that is, the angle iron piece 1 can limit the extension plate 5 and prevent the extension plate 5 from shifting during the construction personnel's stepping. The upper surface of the extension plate 5 Two bolts 8 are fixed at the edge. The cover plate 6 is located on two extension plates 5. Two adjustment ports 7 are opened on the cover plate 6. The two bolts 8 located on the same extension plate 5 pass through the two adjustment ports 7 respectively. Nuts 9 are threaded on the bolts 8, and the bottom of the nuts 9 abuts against the upper surface of the cover plate 6. A protective cover 11 is fixedly fitted on the nuts 9. The protective cover 11 is made of rubber material and has a frustum-shaped structure. Furthermore, the side walls of the extension plates 5 and the cover plate 6 are provided with slopes, which can improve the flatness of the device and prevent the device from affecting the movement of construction personnel.

[0024] The specific working principle of this utility model is as follows:

[0025] During construction, the workers limit the two angle iron pieces 1 in the horizontal direction to prevent them from rotating. Then, they rotate the connecting rod 4 to make the sleeve 3 rotate. Since the threads of the threaded rod 2 are opposite, the two angle iron pieces 1 will move towards or away from each other. This allows the distance between the two angle iron pieces 1 to be adjusted. Based on this adjustment method, the two angle iron pieces 1 are installed at the construction joint or opening so that the inner top surface of the angle iron piece 1 is in contact with the bottom surface, and the inner side of the angle iron piece 1 is in contact with the inner side of the joint or opening.

[0026] Subsequently, the extension plate 5 and the cover plate 6 are installed onto the angle iron 1, so that the inner top surface and inner side of the extension plate 5 are respectively attached to the upper surface and side wall of the angle iron 1, and the positioning plate 10 is attached to the other side wall of the angle iron 1. During the installation process, the bolt 8 can slide in the adjustment port 7. The nut 9 is screwed onto the bolt 8 so that the bottom of the nut 9 abuts against the upper surface of the cover plate 6, thus fixing the cover plate 6 and the extension plate 5. The cover plate 6 and the extension plate 5 can cover the opening and construction joint. The angle iron 1 can prevent the extension plate 5 from shifting. The threaded rod 2 and the connecting rod 4 play a role in strengthening the protection and improving the stability and support performance of the cover plate 6 structure, reducing the safety hazards in the construction process. In addition, the distance between the two angle irons 1 and the two extension plates 5 can be adjusted, which makes the device applicable to openings or construction joints of different sizes, improving the practicality and flexibility of the device, making the device reusable, and improving construction efficiency.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
