Description

Technical Field

[0001] This utility model relates to the field of building construction, and in particular to a device for covering floor openings. Background Technology

[0002] During construction, openings are often left in floor slabs for pipeline installation, equipment installation, or temporary openings may be created during the construction phase. If these openings are not effectively covered in a timely manner, they can easily become safety hazards, potentially leading to accidents such as falls or falling objects, posing a serious threat to the personal safety of construction workers.

[0003] Currently, temporary measures, such as laying wooden boards or steel plates, are often used to cover floor openings on construction sites. However, these temporary covering methods have many shortcomings: Firstly, materials such as wooden boards and steel plates are often difficult to precisely match the size of the opening, resulting in either insufficient coverage or excessive material waste. Furthermore, the mismatch in size can lead to insecure fixing, making them prone to displacement or slippage under external forces. Secondly, temporary covering devices often lack a standardized fixing structure, relying mainly on weight or simple binding, resulting in poor stability and difficulty in coping with frequent disturbances during construction. They are also inconvenient for quick installation and dismantling, affecting construction efficiency. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a floor opening covering device.

[0005] The technical solution includes a rectangular fixing plate, with slots on the left and right sides of the fixing plate.

[0026] Example 1

[0027] See Figures 1 to 5 This utility model provides a floor opening covering device, including a rectangular fixing plate 1. Slots 8 are respectively opened on the left and right sides of the fixing plate 1. The projections of the two slots 8 on the vertical plane are staggered. A left cover plate 2 and a right cover plate 3 are respectively inserted into the slots 8. When both the left cover plate 2 and the right cover plate 3 are located in the fixing plate 1, they are stacked on top of each other.

[0028] A through hole is opened in the middle of the fixing plate 1, and a vertical rod 4 is movably installed in the through hole. The upper end of the vertical rod 4 is threaded, and a nut 5 is threaded on the thread. The nut 5 is located above the fixing plate 1.

[0029] A long strip-shaped lower clamping plate 6 is rotatably installed at the lower end of the upright 4, and the middle part of the lower clamping plate 6 is rotatably connected to the upright 4.

[0030] First, clean the floor slab opening and surrounding area to ensure that there is no garbage or foreign objects within the installation range of the opening 15 covering device, so as to provide a clean and flat working environment for subsequent installation;

[0031] Rotate the lower clamping plate 6 to a position parallel to the length direction of the opening 15, and then slowly place it into the opening 15 until the lower clamping plate 6 can be placed horizontally below the opening 15 to provide a lower support foundation for the device.

[0032] Rotate the upright 4 so that the lower clamping plate 6 is perpendicular to the length direction of the opening 15. Then pull the upright 4 upward to drive the lower clamping plate 6 to gradually rise and stick to the bottom of the opening 15, thus initially forming a stable clamping force below.

[0033] Hold the fixing plate 1 and slip it onto the top of the upright 4. During the process, hold the upright 4 tightly to maintain stability. Slowly lower the fixing plate 1 until it falls precisely to the upper edge of the opening 15 to form the covering base above.

[0034] One hand continues to hold the upper end of the upright 4 to maintain the overall tension, while the other hand slowly puts the nut 5 on the upper part of the upright 4. By rotating the nut 5, it is made to fall to the upper end of the fixing plate 1. Then tighten the nut 5. By using the compression of the nut 5 and the fixing plate 1, as well as the pressing force of the lower clamping plate 6 and the bottom of the opening 15, the entire device is firmly fixed.

[0035] Pull out the left cover plate 2 and the right cover plate 3 from both sides of the fixing plate 1 respectively, and adjust the extension length of the two according to the actual size of the opening 15 to ensure that the coverage area formed by the left cover plate 2, the right cover plate 3 and the fixing plate 1 is greater than the outer edge of the opening 15, so as to achieve complete coverage of the opening 15.

[0036] A support platform 7 is provided at one end of the left cover plate 2 and the right cover plate 3 away from the fixed plate 1. The lower surface of the support platform 7 on the left cover plate 2 and the right cover plate 3 is flush with the lower surface of the fixed plate 1.

[0037] The lower surfaces of the support platforms 7 on the left cover plate 2 and the right cover plate 3 are flush with the lower surface of the fixed plate 1, so that when the left cover plate 2 and the right cover plate 3 extend out of the fixed plate 1 to cover the opening 15, the lower surfaces of the three form a flat support surface, which can better fit with the surface of the floor slab 14, reduce shaking or gaps caused by uneven surfaces, and further improve the stability of the device coverage.

[0038] A slot 8 is opened in the middle of the left cover plate 2 and the right cover plate 3, and the upright 4 slides in the slot 8.

[0039] The slot 8 does not affect the movement of the left cover plate 2 and the right cover plate 3, ensuring the flexibility and continuity of the extension and retraction of the left cover plate 2 and the right cover plate 3, and facilitating the quick adjustment of the coverage area according to the size of the opening 15.

[0040] A sleeve 9 is fitted onto the lower end of the upright 4. A protrusion is provided at the lower end of the sleeve 9, and a groove is provided at the lower end of the upright 4. The protrusion slides in the groove.

[0041] A limiting block 10 is fixedly installed at the upper end of the sleeve 9. The limiting block 10 is rectangular, with two opposite corners being rounded.

[0042] A spring 11 is fitted on the outside of the sleeve 9. One end of the spring 11 is fixedly connected to the limiting block 10, and the other end is fixedly connected to the lower end of the upright 4.

[0043] Two limiting platforms 12 are provided on the lower surface of the fixed plate 1, and the two limiting platforms 12 are symmetrically arranged on both sides of the through hole.

[0044] During installation, after the upright 4 passes through the through hole of the fixing plate 1, the limiting block 10 is inserted between the two limiting platforms 12 on the lower surface of the fixing plate 1. At this time, when the upright 4 is rotated, the limiting block 10 will rotate between the two limiting platforms 12. Due to the obstruction of the limiting platform 12, the limiting block 10 can only complete a 90-degree rotation, which in turn drives the upright 4 and the lower clamping plate 6 to rotate 90 degrees synchronously, so that the lower clamping plate 6 rotates to a state perpendicular to the length direction of the opening 15. During the tightening of the nut 5, the limiting platform 12 can limit the upright 4, preventing the upright 4 from rotating with the nut 5 during the tightening process, thus ensuring that the upright 4 is installed firmly.

[0045] A threaded hole is made at each of the four corners of the fixing plate 1, and a fastening screw 13 is threaded into each threaded hole.

[0046] When the left cover plate 2 and the right cover plate 3 extend out of the fixing plate 1 to cover the opening 15, the positions of the left cover plate 2 and the right cover plate 3 are fixed by the fastening screws 13 to ensure safe use.

[0047] When using this utility model, the floor opening and surrounding area should be cleaned first to ensure that there is no garbage or foreign objects within the installation range of the opening 15 covering device, so as to provide a clean and flat working environment for subsequent installation.

[0048] Rotate the lower clamping plate 6 to a position parallel to the length direction of the opening 15, and then slowly place it into the opening 15 until the lower clamping plate 6 can be placed horizontally below the opening 15 to provide a lower support foundation for the device.

[0049] Rotate the upright 4 so that the lower clamping plate 6 is perpendicular to the length direction of the opening 15. Then pull the upright 4 upward to drive the lower clamping plate 6 to gradually rise and stick to the bottom of the opening 15, thus initially forming a stable clamping force below.

[0050] Hold the fixing plate 1 and slip it onto the top of the upright 4. During the process, hold the upright 4 tightly to maintain stability. Slowly lower the fixing plate 1 until it falls precisely to the upper edge of the opening 15 to form the covering base above.

[0051] One hand continues to hold the upper end of the upright 4 to maintain the overall tension, while the other hand slowly puts the nut 5 on the upper part of the upright 4. By rotating the nut 5, it is made to fall to the upper end of the fixing plate 1. Then tighten the nut 5. By using the compression of the nut 5 and the fixing plate 1, as well as the pressing force of the lower clamping plate 6 and the bottom of the opening 15, the entire device is firmly fixed.

[0052] Pull out the left cover plate 2 and the right cover plate 3 from both sides of the fixing plate 1 respectively, and adjust the extension length of the two according to the actual size of the opening 15 to ensure that the coverage area formed by the left cover plate 2, the right cover plate 3 and the fixing plate 1 is greater than the outer edge of the opening 15, so as to achieve complete coverage of the opening 15.

[0053] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
