[0026] Figure 2 It is a schematic diagram of the connection between the buckle part and the steel wire rope according to one embodiment of the present invention. DETAILED DESCRIPTION

[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] like Figure 1 and 2 As shown, the present invention provides a protective cover plate for edge openings, comprising:

[0029] A cover plate 1 covering the edge opening;

[0030] A buckle portion is arranged at the lower part of the cover plate 1, and the buckle portion includes: a C-shaped steel 2 and a traction rope 3, wherein the C-shaped steel 2 includes a top wall, a side wall and a bottom wall which are vertically connected in sequence; wherein the top wall of the C-shaped steel is connected to the lower end of a first tension bolt 4 passing through the cover plate; and the traction rope 3, wherein the top end of the traction rope is connected to the lower end of a second tension bolt 5 passing through the cover plate;

[0031] The steel wire rope 6 is sleeved in the ring buckle portion, and the two ends of the steel wire rope 6 are respectively fixed on the wall surface 7 on the inner side of the adjacent hole.

[0032] Here, the present invention aims to solve the problems existing in the existing construction site edge opening anti-blowing protective cover plates, and provide a non-rigid shielding device that can not only effectively shield the edge opening, but also ensure rapid pressure release in strong wind conditions.

[0033] The connection between the anti-blowing protection cover and the C-steel, the C-steel beam can improve the strength of the cover, the C-steel can be evenly arranged under the cover, and the C-steel can be fixed under the cover by the first pair of tension bolts to form a stable supporting structure to enhance the stability and bearing capacity of the shielding plate, effectively prevent deformation or damage caused by strong wind or external force, and ensure the reliability of the shielding effect.

[0034] At the same time, a buckle is installed under the cover plate, the upper end of the buckle is fixed to the lower part of the cover plate by a second bolt, and the lower end of the buckle is connected to the C-shaped steel by bolts to form a ring structure, and the wire rope is inserted into the buckle. This design ensures that the buckle, the shielding plate and the C-shaped steel have good connection strength and stability, ensuring that when the cover plate is blown by strong winds, the buckle at the bottom restricts the wire rope, which can keep the cover plate stable and will not completely fall off from above the edge hole, thereby ensuring the safety and reliability of the entire shielding device.

[0035] The steel cable passes through the buckle to form a non-rigid connection. This connection method can provide a certain buffer and release pressure in strong wind conditions to prevent the entire edge hole protection cover from being damaged or falling off due to excessive wind force. It can also provide a stable protection effect under normal conditions, effectively preventing people from accidentally falling and objects from being blown off by the wind, ensuring the safety of the construction site.

[0036] The structure of the present invention is simple, easy to install and maintain, can effectively shield the edge opening, and can ensure the rapid release of structural pressure in strong wind conditions, reducing construction costs and time costs, and improving construction efficiency. At the same time, it has a convenient disassembly function, which is convenient for rapid installation and disassembly at different construction stages, improving construction efficiency and safety.

[0037] In one embodiment of the protective cover plate for edge openings of the present invention, the cover plate 1 is a rock wool core colored steel plate.

[0038] Here, the rock wool core color steel plate uses color-coated steel plate as the surface material and rock wool as the core material. It has the advantages of excellent fire resistance, good thermal insulation performance, good sound absorption and noise reduction effect, convenient installation and high construction efficiency.

[0039] In one embodiment of the protective cover plate for edge openings of the present invention, there are multiple buckle parts which are arranged in a straight line at intervals at the lower part of the cover plate, and each steel wire rope passes through all the buckle parts on the same straight line.

[0040] like Figure 2 As shown, in one embodiment of the protective cover plate for edge openings of the present invention, the traction rope 3 is in the shape of a fishhook, including a long end 33 and a short end 32 .

[0041] In one embodiment of the protective cover plate for edge openings of the present invention, the long end is connected to the lower end of the first tension bolt passing through the cover plate, and the short end is connected to the bottom wall of the C-shaped steel.

[0042] In one embodiment of the protective cover plate for edge openings of the present invention, embedded parts are fixedly installed on the inner sides of the edge openings, and both ends of the steel wire rope are connected to the embedded parts respectively.

[0043] Here, embedded parts are installed on the inner side of the edge opening at a position parallel to the C-shaped steel, and steel wire ropes are connected between the two embedded parts.

[0044] Preferably, Figure 2 As shown, the arc hook portion 31 of the fishhook-type traction rope 3 is lower than the bottom wall of the C-shaped steel, the horizontal height of the short end 32 connected to the arc hook portion 31 is close to the horizontal height of the bottom wall, and the horizontal height of the long end 33 connected to the arc hook portion 31 is close to the horizontal height of the top wall of the C-shaped steel. When the cover plate is blown up, the arc hook portion of the traction rope limits the steel wire rope.

[0045] Here, the range of the horizontal height difference is 1 to 2 centimeters.

[0046] When the cover is blown up by external forces such as strong wind, it will drive the steel wire rope connected to it to move upward. Due to the special fishhook shape and position setting of the traction noose, the steel wire rope will be blocked by the arc hook when it moves upward. The arc hook limits the upward movement range of the steel wire rope, making it impossible for the steel wire rope to escape its control, thereby limiting the height and displacement of the cover being blown up, preventing the cover from being completely blown away, playing a protective and limiting role, and reducing safety hazards.

[0047] like Figure 2 As shown, in one embodiment of the protective cover plate for edge openings of the present invention, a hook 10 is provided on the embedded part 9, and the hook is connected to one end of the steel wire rope.

[0048] Here, a hook 10 is provided on the embedded part to facilitate installation and removal of the wire rope, and to facilitate rapid adjustment and replacement according to actual construction requirements, thereby improving construction efficiency and flexibility.

[0049] After installation, the device can be debugged to ensure that it has good protection effect under normal circumstances and can effectively prevent people from accidentally falling and objects from being blown off by the wind; at the same time, check that the device can remain stable in strong winds and will not be easily damaged or fall off. After acceptance, it will be put into use to provide reliable safety protection for the construction site.

[0050] In one embodiment of the protective cover plate for edge openings of the present invention, polyurethane foam 8 is provided on the contact surface between the top of the edge opening and the bottom surface of the cover plate to play a role in buffering and shock absorption.

[0051] like Figure 2 As shown, in one embodiment of the protective cover plate for edge openings of the present invention, the long end of the traction rope 3 is connected to a second connecting plate 12, and the second connecting plate 12 is connected to the lower part of the second tension bolt.

[0052] like Figure 2As shown, in one embodiment of the protective cover plate for edge openings of the present invention, the short end of the traction rope is connected to a first connecting plate 11, and the first connecting plate 11 is connected to the lower wall of the C-shaped steel 2 by bolts.

[0053] In summary, the anti-blowing protection cover plate of the present invention achieves the following technical effects through the structural design of the ring buckle and the steel cable:

[0054] Safety: In strong wind conditions, the cover can maintain a certain controllable connection with the adjacent opening, ensuring that pressure can be effectively released under the action of wind, avoiding damage or falling off of the shielding device due to excessive wind, thereby protecting the safety of the building structure and the safety of personnel and equipment on the construction site.

[0055] Protection: Under normal circumstances, the cover plate and the buckle structure can effectively prevent the cover plate from being blown away by strong winds, and prevent people from accidentally falling into the edge hole, providing reliable safety protection for the construction site and reducing the risk of safety accidents.

[0056] Reliability: The use of bolt connection and embedded parts fixation ensures that the various components of the device are firmly connected and the overall structure is stable.
