Description

Technical Field

[0001] This utility model relates to a protective device for floor openings, specifically a novel adjustable protective device for floor openings. Background Technology

[0002] In construction projects, reserved openings in floor slabs have always been areas with significant safety hazards. As the number of building floors increases, the number of reserved openings on construction sites gradually increases, and falls from heights occur frequently. The safety hazards around reserved openings are significant, and sealing reserved openings plays an important role in preventing safety accidents.

[0003] However, while existing floor opening protection devices are structurally stable, they are not adjustable, and the reserved openings vary in size, sometimes resulting in the protection device failing to completely seal the opening. Therefore, this application designs a novel adjustable floor opening protection device. Utility Model Content

[0004] The main objective of this disclosure is to provide a novel adjustable protective device for floor openings, so as to effectively solve the problems raised by the inventors in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A novel adjustable protective device for floor openings includes adjustable positioning square steel and a telescopic protective plate. Two adjustable positioning square steels are provided, arranged in parallel. A linear slide rail groove is formed on the side of each of the two adjustable positioning square steels that is close to each other. The telescopic protective plate is slidably connected to the two linear slide rail grooves on both sides. Several evenly distributed mounting holes are formed on the top of each adjustable positioning square steel, each hole leading into a linear slide rail groove. Two stop bolts are screwed into the two mounting holes on each adjustable positioning square steel, and the two stop bolts are located on the front and rear sides of the telescopic protective plate within the linear slide rail groove.

[0007] Preferably, the bottom end of the stop bolt extends downward and contacts the inner bottom wall of the linear slide rail groove.

[0008] Preferably, locking bolts are screwed into the two mounting holes at the beginning and end of the adjustable positioning square steel, and alignment holes are opened at the front and rear ends of the bottom wall of the linear slide rail groove, with the two alignment holes corresponding to the two mounting holes at the beginning and end, and the locking bolts passing through the alignment holes.

[0009] Preferably, the telescopic protective plate consists of a first sliding plate, a telescopic plate, and a second sliding plate. The two sides of the telescopic plate are slidably connected to the inner cavities of the first and second sliding plates, respectively. The sides of the first and second sliding plates that are far apart from each other slide in two linear slide rail grooves.

[0010] Preferably, an observation tube is embedded in the middle of the telescopic plate.

[0011] Preferably, both sides of the telescopic plate are fixedly connected with protrusions, and the two protrusions are respectively limited and slidably connected in the cavities of the first slide plate and the second slide plate, and the size of the protrusions is larger than the inlet size of the cavity.

[0012] In view of this, compared with the prior art, the beneficial effects of this utility model are:

[0013] (i) In this application, the two sides of the telescopic protective plate are slid into the linear slide rail grooves on the two adjustable positioning square steels, and then placed at the floor opening. The position of the telescopic protective plate is adjusted so that it can completely cover the floor opening. The stop bolt is screwed into the installation hole so that the stop bolt blocks the telescopic protective plate and prevents large displacement. Then the adjustable positioning square steel is fixed by the locking bolt, thereby protecting the floor opening. The operation is simple and suitable for on-site installation.

[0014] (ii) In this application, since the distance between the No. 1 sliding plate and the No. 2 sliding plate can be adjusted, the length of the telescopic plate that is exposed changes, thereby changing the area of ​​the telescopic protective plate to adapt to different sizes of floor openings. The number of telescopic protective plates between the two adjustable positioning square steels can be selected according to the requirements, and multiple of the new type of adjustable protective devices for floor openings can also be neatly arranged and installed.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5 The present invention provides the following embodiments:

[0024] A novel adjustable protective device for floor openings includes an adjustable positioning square steel 1 and a telescopic protective plate 2. Two adjustable positioning square steel 1s are provided, arranged in parallel. A linear slide rail groove 3 is provided on the side of each adjustable positioning square steel 1 that is close to the other. The telescopic protective plate 2 is slidably connected to the two linear slide rail grooves 3 on both sides. Several evenly distributed mounting holes 4 are provided on the top of the adjustable positioning square steel 1, each hole leading into the linear slide rail groove 3. Two stop bolts 5 are screwed into the two mounting holes 4 on each adjustable positioning square steel 1, with the two stop bolts 5 located on the front and rear sides of the telescopic protective plate 2 within the linear slide rail groove 3, respectively. The bottom end of the stop bolt 5 extends downwards and contacts the inner bottom wall of the linear slide rail groove 3.

[0025] Specifically, locking bolts 6 are screwed into the two mounting holes 4 at the beginning and end of the adjustable positioning square steel 1. Alignment holes are opened at the front and rear ends of the bottom wall of the linear slide rail groove 3, and the two alignment holes correspond to the two mounting holes 4 at the beginning and end. The locking bolts 6 pass through the alignment holes.

[0026] Specifically, the telescopic protective plate 2 consists of a first sliding plate 7, a telescopic plate 8, and a second sliding plate 9. The two sides of the telescopic plate 8 are slidably connected to the inner cavities of the first sliding plate 7 and the second sliding plate 9, respectively. The sides of the first sliding plate 7 and the second sliding plate 9 that are far apart from each other slide in two linear slide rail grooves 3, respectively. Both sides of the telescopic plate 8 are fixedly connected with protrusions 11, and the two protrusions 11 are respectively limited and slidably connected to the cavities of the first sliding plate 7 and the second sliding plate 9. The size of the protrusions 11 is larger than the inlet size of the cavity.

[0027] Specifically, the telescopic plate 8 has an observation tube 10 embedded in its middle.

[0028] The specific implementation method of this embodiment is as follows: slide the two sides of the telescopic protective plate 2 into the linear slide rail grooves 3 on the two adjustable positioning square steels 1 respectively, then place it at the floor opening, adjust the position of the telescopic protective plate 2 so that it can completely cover the floor opening, screw the stop bolt 5 into the installation round hole 4 so that the stop bolt 5 blocks the telescopic protective plate 2 and prevents large displacement, and then fix the adjustable positioning square steel 1 with the locking bolt 6, thereby protecting the floor opening. The operation is simple and suitable for on-site installation and application.

[0029] Since the distance between the first sliding plate 7 and the second sliding plate 9 can be adjusted, the length of the telescopic plate 8 that is exposed changes, thereby changing the area of ​​the telescopic protective plate 2, so that it can be adapted to different sizes of floor openings. The number of telescopic protective plates 2 between the two adjustable positioning square steels 1 can be selected according to the needs, or multiple of these new adjustable protective devices for floor openings can be neatly arranged and installed.
