Description

Technical Field

[0001] This utility model relates to the technical field of building construction, and in particular to a safety protection device for reserved openings in the main structure of a building. Background Technology

[0002] The main structure of a building refers to the load-bearing structural system built upon the foundation, which receives, bears, and transmits all superstructure loads of the construction project, maintaining the structural integrity, stability, and safety. The components of the main structure include concrete works, masonry works, and steel structure works.

[0003] During the actual construction of a building, it is usually necessary to reserve installation openings. After the openings are reserved, in order to prevent construction waste from falling from the upper layers and causing injury to people, a shield is usually placed above the opening. However, in actual use, the shield is prone to displacement, and people may accidentally step onto the shield, posing a certain safety hazard. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, the technical problem to be solved by this utility model is to provide a safety protection device for the reserved opening in the main construction of a building. This device can not only be firmly fixed in the reserved opening, improving the stability during use, but also serve as a warning to personnel.

[0005] To achieve the above objectives, this utility model provides a safety protection device for reserved openings in the main construction of a building, including a second protective plate for being placed inside the reserved opening and a first protective plate for covering the reserved opening. The second protective plate is centrally fixed to the lower end of the first protective plate. A through-hole installation cavity is horizontally opened inside the second protective plate, and abutment plates are provided at both ends of the installation cavity. The abutment plates are pressed against the inner wall of the reserved opening under the drive of a first driving mechanism located inside the installation cavity. A rectangular groove is opened in the center of the first protective plate, and two T-shaped sliding grooves are symmetrically opened on both sides of the rectangular groove. Two warning plates are slidably connected in the two T-shaped sliding grooves and rotatably connected together by a rotating shaft. A second driving mechanism is installed in the rectangular groove to drive the two warning plates upward so that the two warning plates are arranged in a triangle above the first protective plate.

[0006] Preferably, the first drive mechanism includes a first dual-axis motor, a threaded column connected to two output ends of the first dual-axis motor, and an internally threaded top cylinder threadedly connected to the threaded column, with the abutment plate installed at the end of the internally threaded top cylinder.

[0007] Furthermore, an elastic anti-slip pad is installed on the side of the abutment plate facing the inner wall of the reserved opening, and a pressure sensor is installed inside the elastic anti-slip pad.

[0008] Furthermore, two symmetrical limiting sliders are installed on the surface of the internally threaded top cylinder, and a limiting groove is provided on the inner wall of the mounting cavity to limit the sliding of the limiting sliders.

[0009] Preferably, the second drive mechanism includes a second dual-axis motor installed at the center of the rectangular groove, a lead screw connected to the two output ends of the second dual-axis motor, a sliding block threadedly connected to the lead screw, and a top rod rotatably connected to the top of the sliding block. The top ends of the top rods are rotatably connected to the lower surfaces of the corresponding warning plates.

[0010] Preferably, the inner walls of the two T-shaped grooves are slidably connected to T-shaped sliders, and the bottom ends of the two warning plates are rotatably connected to the T-shaped sliders located in the two T-shaped grooves.

[0011] Furthermore, the top and bottom walls of the mounting cavity are respectively equipped with a battery and a PLC controller, and the pressure sensor and the first dual-axis motor are both electrically connected to the PLC controller.

[0012] In summary, compared with the prior art, the safety protection device for reserved openings in the main construction of buildings of this utility model has at least the following beneficial effects:

[0013] 1. In actual use, the second protective plate is placed into the reserved opening, so that the first protective plate covers the reserved opening. Then, the first dual-axis motor is started. The rotation of the first dual-axis motor drives the threaded column to rotate. The rotation of the threaded column drives the clamping plate and elastic anti-slip pad of the internal threaded top cylinder to press against the inner wall of the reserved opening. When the pressure value sensed by the pressure sensor reaches the predetermined value, the pressure sensor transmits the signal to the PLC controller. The PLC controller controls the first dual-axis motor to shut down, thereby achieving the purpose of effectively fixing the device and improving the stability of the device in actual use.

[0014] 2. Under the action of the second dual-axis motor, the two lead screws are driven to rotate. The rotation of the two lead screws lifts the two warning plates upward through the two sliding blocks and the top rod, so that the two warning plates are set in a triangle on the upper surface of the first protective plate, so as to achieve the purpose of warning personnel.

Detailed Implementation

[0020] 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.

[0021] See below Figures 1-3 This utility model provides a detailed description of the safety protection device for reserved openings during the construction of the main building structure.

[0022] The safety protection device for the reserved opening in the main construction of the building structure of this utility model includes a first protective plate 1 and a second protective plate 2 which is fixedly connected to the lower surface of the first protective plate 1 in the center. The cross-section of the first protective plate 1 is larger than the reserved opening, and the cross-section of the second protective plate 2 is smaller than the reserved opening, so that during use, the second protective plate 2 can be placed into the reserved opening, and the first protective plate 1 can cover the top of the reserved opening.

[0023] An installation cavity is horizontally formed inside the second protective plate 2, and a first dual-axis motor 3 is installed in the center of the inner wall of the installation cavity. Threaded posts 4 are installed on both output ends of the first dual-axis motor 3. Internal threaded top cylinders 5 are threadedly connected to both of these threaded posts 4. Two symmetrical limiting sliders are installed on the surface of the internal threaded top cylinder 5. A limiting groove is formed on the inner wall of the installation cavity for the limiting sliders to slide. The limiting sliders cooperate with the limiting groove to prevent the internal threaded top cylinder 5 from slipping off the threaded posts 4.

[0024] The first dual-axis motor 3 can drive the threaded columns 4 at both ends of its shaft to rotate in opposite directions, so that the two internal threaded top cylinders 5 can move simultaneously toward each other or toward each other.

[0025] Furthermore, each of the two internally threaded top cylinders 5 is provided with a retaining plate 6 at its end. An elastic anti-slip pad 14 is installed on the side of the retaining plate 6 facing the inner wall of the reserved opening. A pressure sensor 15 is installed inside the elastic anti-slip pad 14. The retaining plate 6 and the elastic anti-slip pad 14 extend or retract into the mounting cavity under the action of the internally threaded top cylinder 5.

[0026] The aforementioned first dual-axis motor 3, threaded column 4, and internal threaded top cylinder 5 constitute the first driving mechanism. The first driving mechanism drives the clamping plate 6 and elastic anti-slip pad 14 to press against the inner wall of the reserved opening to fix the second protective plate 2 in the reserved opening.

[0027] Meanwhile, the present invention also provides a storage battery 12 and a PLC controller 13 on the top and bottom walls of the mounting cavity, respectively. The pressure sensor 15 and the first dual-axis motor 3 are electrically connected to the PLC controller 13. Specifically, the storage battery 12 supplies power to the motor, the PLC controller 13 and the sensor or is used as a backup power source.

[0028] In actual use, the second protective plate 2 is placed into the opening, so that the first protective plate 1 covers the reserved opening. Then, the first dual-axis motor 3 is started. The rotation of the first dual-axis motor 3 drives the threaded column 4 to rotate. The rotation of the threaded column 4 drives the clamping plate 6 of the internal threaded top cylinder 5 and the elastic anti-slip pad 14 to press against the inner wall of the reserved opening. When the pressure value sensed by the pressure sensor 15 reaches the predetermined value, the pressure sensor 15 transmits the signal to the PLC controller 13. The PLC controller 13 controls the first dual-axis motor 3 to shut down, thereby achieving the purpose of effectively fixing the device and improving the stability of the device in actual use.

[0029] To further enhance the warning effect of this device, a rectangular groove is provided in the center of the first protective plate 1, and two T-shaped sliding grooves are symmetrically provided on both sides of the rectangular groove. A second dual-axis motor 7 is installed in the center of the rectangular groove. Both output ends of the second dual-axis motor 7 are equipped with lead screws 8, and both lead screws 8 are threadedly connected to sliding blocks 9, which slide in the sliding grooves of the rectangular groove. The tops of the two sliding blocks 9 are rotatably connected to top rods 16, and the tops of the two top rods 16 are rotatably connected to the lower surfaces of the two warning plates 11, which are rotatably connected together by rotating shafts. T-shaped sliders 10 are slidably connected to the inner walls of the two T-shaped sliding grooves, and the bottom ends of the two warning plates 11 are rotatably connected to the T-shaped sliders 10 located in the two T-shaped sliding grooves.

[0030] The aforementioned second dual-axis motor 7, lead screw 8, sliding block 9, and push rod 16 constitute the second drive mechanism. The second drive mechanism drives the two warning plates 11 to be pushed upwards to achieve the effect of warning personnel.

[0031] Furthermore, both the second dual-axis motor 7 and the first dual-axis motor 3 are connected to an external handheld remote control. It should be noted that the second dual-axis motor 7 and the first dual-axis motor 3 of this invention can be TUNYO 100-7500W motors. The second dual-axis motor 7 can drive the lead screws 8 at both ends to rotate in opposite directions, causing the two sliding blocks 9 to move simultaneously towards or away from each other.

[0032] In actual use, after the device is fixed in the reserved opening, it can drive the two lead screws 8 to rotate under the action of the second dual-axis motor 7. The rotation of the two lead screws 8 pushes the two warning plates 11 upward through the two sliding blocks 9 and the top rod 16, so that the two warning plates 11 are set in a triangle above the first protective plate 1, so as to achieve the purpose of warning personnel.

[0033] Below, refer to Figure 1-3 Based on the above description of structural technical features, the working principle of the safety protection device for reserved openings in the main building construction of this utility model is introduced:

[0034] The second protective plate 2 is placed into the reserved opening, so that the first protective plate 1 covers the reserved opening. Then the first dual-axis motor 3 is started. The rotation of the first dual-axis motor 3 drives the threaded column 4 to rotate. The rotation of the threaded column 4 drives the clamping plates 6 and elastic anti-slip pads 14 of the two internal threaded top cylinders 5 to press against the inner wall of the reserved opening. When the pressure value sensed by the pressure sensor 15 reaches the predetermined value, the pressure sensor 15 transmits the signal to the PLC controller 13. The PLC controller 13 controls the first dual-axis motor 3 to shut down, thereby achieving the purpose of effectively fixing the device and improving the stability of the device in actual use.

[0035] Moreover, in actual use, when the device is fixed in the reserved opening, it can drive the two lead screws 8 to rotate under the action of the second dual-axis motor 7. The rotation of the two lead screws 8 pushes the two warning plates 11 upward through the two sliding blocks 9 and the top rod 16, so that the two warning plates 11 are set in a triangle on the upper surface of the first protective plate 1, so as to achieve the purpose of warning personnel.

[0036] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any transformations or substitutions that can be understood by those skilled in the art within the technical scope disclosed in this utility model should be included within the scope of this utility model.
