Description

Technical Field

[0001] The utility model relates to the technical field of construction equipment, in particular to a construction protection device. Background Art

[0002] During the construction process, in order to facilitate the concrete delivery pipe to pass through the concrete floor, some horizontal holes will be reserved during the pouring of the concrete floor. However, when the concrete pouring operation is not in progress, the horizontal holes will be exposed. At this time, foreign objects are likely to fall from the horizontal holes and form falling objects. In order to avoid the above situation, it is necessary to cover the horizontal holes with covering plates for protection when the concrete pouring operation is not in progress to ensure that the construction can be carried out safely.

[0003] The above-mentioned and existing related technologies have the following defects: when installing the covering plate, the covering plate is firstly used to cover the horizontal hole, and then the covering plate is fixed to the concrete floor with the help of nails. Therefore, when the covering plate is frequently disassembled and installed, it is necessary to frequently drive the nails into and out of the floor, which can easily damage the floor and reduce the practicality of the covering plate.

[0004] To this end, we propose a construction protection device. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-4The utility model provides a technical solution: a construction protection device, including a covering plate 1, a cross hole 2 is opened on the surface of the covering plate 1, four sliders 3 are slidably connected to the inner wall of the cross hole 2, the lower surface of the slider 3 is rotatably connected to a rotating plate 4, the lower surface of the slider 3 is fixedly connected to a positioning plate 5, the lower end of the positioning plate 5 is against the surface of the rotating plate 4, the slider 3 is internally threaded with a bolt 6, the lower end of the bolt 6 is rotatably connected to a limiting plate 7, the limiting plate 7 is slidably connected to the slider 3, and the lower surface of the covering plate 1 is fixedly connected to a flexible ring 16.

[0022] like Figure 2 and Figure 3 as well as Figure 4 As shown, the surface of the rotating plate 4 is slidably sleeved with an adjusting tube 8, and a latch 9 is slidably connected inside the adjusting tube 8. A plurality of insertion holes 17 are opened on the surface of the rotating plate 4. The size of the latch 9 is adapted to the size of the insertion hole 17. After the latch 9 is inserted into the insertion hole 17, the insertion hole 17 reaches the position of limiting the latch 9, thereby limiting the position of the adjusting tube 8. By changing the position of the adjusting tube 8, the position of the covering plate 1 can be conveniently fixed on floors of different thicknesses. The arc surface of the latch 9 is sleeved with a spring 10, and the two ends of the spring 10 are respectively fixedly connected to the latch 9 and the adjusting tube 8. When the spring 10 contracts, the latch 9 will slide with the help of the pulling force of the spring 10, and the spring 10 can achieve the effect of automatically resetting the latch 9. A baffle 11 is fixedly connected to the surface of the adjusting tube 8, and the vertical section of the baffle 11 is "L"-shaped. When the latch 9 contacts the baffle 11, the baffle 11 will limit the moving distance of the latch 9 to prevent the latch 9 from being out of contact with the adjusting tube 8.

[0023] like Figure 1 and Figure 2 As shown, the upper surface of the cover plate 1 is rotatably connected to a cover plate 12, and the surface of the cover plate 12 is fixedly connected to a buffer strip 14, which is a rubber strip. The cover plate 12 is rotated to cover the cross hole 2 to prevent foreign matter from falling into the cross hole 2 and affecting the normal sliding of the slider 3 along the inner wall of the cross hole 2. The surface of the cover plate 12 is fixedly connected to a plurality of protrusions 13, which can increase the friction force on the surface of the cover plate 12 to prevent the staff from slipping when walking on the surface of the cover plate 12. The surface of the cover plate 1 is fixedly connected to an inclined frame 15, which can prevent the bulge of the cover plate 1 from affecting the normal walking of the staff.

[0024] Working principle: When the covering plate 1 is needed to seal the horizontal hole on the floor, first pull the latch 9 in the direction away from the adjusting tube 8. The latch 9 will slide and disengage from the socket 17. At the same time, the latch 9 will stretch the spring 10. When the latch 9 contacts the baffle 11, the baffle 11 will limit the movement distance of the latch 9 to prevent the latch 9 from disengaging from the adjusting tube 8. Then slide the adjusting tube 8 along the surface of the rotating plate 4. When the adjusting tube 8 slides to a suitable position, release the latch 9. At this time, the spring 10 begins to contract, and the latch 9 will be inserted into the socket 17 with the help of the tension of the spring 10. The plug hole 17 reaches the position of the limiting latch 9, thereby limiting the position of the adjusting tube 8. By changing the position of the adjusting tube 8, the position of the covering plate 1 can be conveniently fixed on the floor slabs of different thicknesses. Then, the covering plate 1 is covered on the top of the horizontal hole, and the horizontal hole is shielded and protected by the covering plate 1. At this time, the positioning plate 5 will limit the position of the rotating plate 4, so that the rotating plate 4 is in an inclined state, and then the cover plate 12 is rotated, and then the slider 3 is slid along the inner wall of the cross hole 2. The sliding of the slider 3 will drive the rotating plate 4 to move, and the movement of the rotating plate 4 will drive the adjusting tube 8 to move. When the adjusting tube 8 is aligned with the horizontal After the inner wall of the hole is in contact, the bolt 6 is rotated. The bolt 6 will drive the limit plate 7 to move upward with the help of the thread. The limit plate 7 moves and contacts with the cover plate 1. At this time, the limit plate 7 will limit the position of the bolt 6 with the help of the friction between the cover plate 1, thereby limiting the position of the rotating plate 4 and the adjusting tube 8. Then repeat the above operation to make the other three adjusting tubes 8 contact with the inner wall of the horizontal hole, and rotate the bolt 6 to fix the position of the adjusting tube 8. When the four adjusting tubes 8 are in contact with the inner wall of the horizontal hole, the position of the cover plate 1 can be fixed, and then the cover plate 12 is rotated in the opposite direction to make The cover plate 12 covers the cross hole 2 to prevent foreign matter from falling into the cross hole 2 and affecting the normal sliding of the slider 3 along the inner wall of the cross hole 2. The rotation of the cover plate 12 will cause the buffer strip 14 to contact the cover plate 1. The rubber buffer strip 14 can reduce the collision force between the cover plate 12 and the cover plate 1 to prevent the cover plate 12 from being damaged. At this time, the inclined frame 15 can prevent the cover plate 1 from bulging and affecting the normal walking of the staff. The protrusion 13 can increase the friction force on the surface of the cover plate 12 to prevent the staff from slipping when walking on the surface of the cover plate 12.
