Description

Technical Field

[0001] This utility model relates to the field of building safety technology, specifically a safety protection device for openings. Background Technology

[0002] During building construction, after the main structure is completed, chimney openings are often left. Without proper safety measures, these openings pose significant safety hazards, with many construction workers potentially falling in and causing serious accidents. Current methods for protecting these chimney openings include: 1. Covering the opening with a wooden plank larger than the opening. However, this method allows the plank to move easily, and if a corner of the plank is suspended in the opening, it poses a significant safety risk to workers standing on it; 2. Using protective frames around the opening to warn workers not to approach and prevent falls. However, these frames are expensive, easily damaged during construction, and not very practical. Therefore, we propose a chimney opening safety protection device. Utility Model Content

[0003] The purpose of this utility model is to provide a safety protection device for openings, in order to address the shortcomings of the existing technology and solve the problems mentioned in the background.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a safety protection device for a flue opening, comprising a wooden board limiting clip and a wooden board installed at the edge of the flue opening. The wooden board limiting clip consists of a vertical plate A, a horizontal plate, and a vertical plate B. The top center of the horizontal plate is connected to the vertical plate A, and the bottom side of the horizontal plate is connected to the vertical plate B. Several wooden board limiting clips are provided, all installed on one side of the flue opening. One end of the wooden board abuts against the connection between the vertical plate A and the horizontal plate, and the other end of the wooden board abuts against the wall on the top side of the flue opening.

[0005] Furthermore, both vertical plate A and vertical plate B are welded to the horizontal plate.

[0006] Furthermore, the vertical plate A, the horizontal plate, and the vertical plate B are all made of carbon steel plates.

[0007] Furthermore, the width of the horizontal plate is greater than the height of the vertical plates A and B.

[0008] Furthermore, the height of the vertical plate B is greater than the height of the vertical plate A.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: The safety protection device consists of several clips and a wooden board. The clips only need to be placed at the edge of the hole, and then one end of the wooden board is pressed against the clips and the other end is pressed against the wall to limit and fix the wooden board. When the construction worker steps on the wooden board, the wooden board will slowly descend under the action of the person's weight, which will increase the squeezing force between the wooden board and the wall, making the wooden board more and more secure and preventing it from moving. This prevents the corner of the wooden board from being suspended in the air, thus ensuring strong safety. Attached Figure Description

[0010] Figure 1 This is a schematic diagram of the structure of this utility model; Figure 2 This is a structural schematic diagram of the wooden board limiting clip of this utility model.

[0011] In the diagram: 1. Wooden board limiting clip; 2. Wooden board; 3. Flue cavity; 101. Vertical board A; 102. Horizontal board; 103. Vertical board B. Detailed Implementation

[0012] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of the present invention.

[0013] Example: Please refer to Figure 1-2 This utility model provides a technical solution: a safety protection device for a flue opening, including a wooden board limiting clip 1 and a wooden board 2 set at the edge of the flue opening 3. The wooden board limiting clip 1 is composed of a vertical plate A101, a horizontal plate 102, and a vertical plate B103. The top center of the horizontal plate 102 is connected to the vertical plate A101, and the bottom side of the horizontal plate 102 is connected to the vertical plate B103. There are several wooden board limiting clips 1, all set on one side of the flue opening 3. One end of the wooden board 2 abuts against the connection between the vertical plate A101 and the horizontal plate 102, and the other end of the wooden board 2 abuts against the wall on the top side of the flue opening 3.

[0014] Both vertical plate A101 and vertical plate B103 are welded to horizontal plate 102.

[0015] Vertical plate A101, horizontal plate 102, and vertical plate B103 are all made of carbon steel plate.

[0016] The width of the horizontal plate 102 is greater than the height of the vertical plates A101 and B103.

[0017] The height of vertical plate B103 is greater than the height of vertical plate A101.

[0018] Working principle: This is a safety protection device for openings. When in use, several wooden board limiting clips 1 are placed at the edge of the flue opening 3, so that the bottom of the horizontal board 102 is in contact with the ground and the side of the vertical board B103 is in contact with the side wall of the opening. Then, one end of the wooden board 2 is pressed against the connection between the vertical board A101 and the horizontal board 102, and the other end of the wooden board 2 is pressed against the wall, thereby fixing the wooden board 2. When the construction worker accidentally steps on the wooden board 2, the wooden board 2 will slowly squeeze the wooden board limiting clips 1 and the wall due to the worker's weight. Since the wall cannot be moved and the wooden board limiting clips 1 cannot be moved, the wooden board will not move. It is highly safe, and it is very simple and convenient to assemble and disassemble, making it highly practical.

[0019] The above embodiments merely illustrate the implementation of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
