Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a steel grating device that can be opened or closed. Background Technology

[0002] As is well known, large venue structures mainly adopt tubular truss or space frame structural systems. To ensure the smooth passage of maintenance personnel, walkways are arranged on the structure, and steel grating is laid on the walkways to ensure the smooth passage of personnel.

[0003] With the rapid development of architecture, the planning and use of building space are becoming increasingly sophisticated in order to achieve both functional and aesthetic effects. This includes fully utilizing the space beneath steel walkways to house mechanical, electrical, and wiring equipment, thus meeting the overall functional requirements of the building.

[0004] To meet the needs of subsequent equipment maintenance, the steel grating on the walkway needs to be openable and closable to meet diverse usage requirements. However, steel grating is lightweight, deforms easily, and lacks reliable connection points. Without proper fixing, it is very easy for it to be blown off from a height, affecting personnel safety. Therefore, achieving the opening and closing function is very difficult. Utility Model Content

[0005] This invention aims to at least partially solve one of the problems of the prior art. To this end, this invention proposes a steel grating device that can be opened or closed, suitable for steel structure walkways, which is not only convenient to open or close, but also structurally robust.

[0006] A steel grating device capable of being opened or closed according to certain embodiments of the present invention is applied to a steel structure walkway, comprising two main walkway beams, a crossbeam, a middle beam, and a steel grating; the two main walkway beams are arranged parallel to each other and spaced apart; the crossbeam connects the two main walkway beams; the middle beam is disposed between the two main walkway beams and is connected to the crossbeam, and is arranged parallel to and spaced apart from the two main walkway beams; the steel grating is disposed between the middle beam and one of the main walkway beams, with the side of the steel grating closest to the middle beam being a first... The first side of the steel grating is the side closest to the main beam of the walkway. The first side of the steel grating is rotatably connected to the middle beam of the walkway. The steel grating can rotate upward or downward relative to the middle beam of the walkway. When the steel grating rotates downward to a horizontal position, the second side of the steel grating can rest on the adjacent main beam of the walkway. A locking structure is provided between the second side of the steel grating and the adjacent main beam of the walkway. The locking structure can lock the steel grating and the main beam of the walkway together, or the locking structure can release the locking connection between the steel grating and the main beam of the walkway.

[0007] The steel grating device that can be opened or closed according to this utility model has the following beneficial effects: By setting a middle beam between two main walkway beams, the first side of the steel grating is rotatably connected to the middle beam, and the second side of the steel grating is locked to the adjacent main walkway beam. With this structure, when workers need to open the steel grating, they only need to unlock the locking connection between the steel grating and the main walkway beam using the locking structure. At this time, the steel grating can rotate upwards relative to the middle beam to open the steel walkway. When the steel grating rotates downwards relative to the middle beam and lowers, allowing the second side of the steel grating to rest on the adjacent main walkway beam, the locking structure locks the steel grating and the main walkway beam together to close the steel walkway. At this time, the first side of the steel grating is connected to the middle beam, and the second side is locked to the adjacent main walkway beam, thus firmly fixing the steel grating to the main and middle beams, effectively preventing the steel grating from being blown off the steel walkway. This ensures the safety of pedestrians and is simple and convenient to operate.

The square tube is arranged along the length direction of the middle beam of the walkway. A hinge is provided between the first side of the steel grating and the square tube. The first connecting member of the hinge is connected to the first side of the steel grating, and the second connecting member of the hinge is connected to the square tube.

[0010] In some embodiments of this utility model, a connecting piece is welded to the upper surface of the first side of the steel grating, the first connecting piece is welded to the connecting piece, and the second connecting piece is welded to the upper surface of the square tube.

[0011] In some embodiments of this utility model, the number of hinges provided between the first side of the steel grating and the square tube is two, and the two hinges are arranged at intervals along the length direction of the steel grating.

[0012] In some embodiments of this utility model, the locking structure includes a pin, a first pin hole, and a second pin hole. The first pin hole is located on the second side of the steel grating, and the second pin hole is located on the main beam of the walkway. When the steel grating is rotated downwards and the second side of the steel grating rests on the main beam of the walkway, the first pin hole and the second pin hole are aligned, and the pin can be inserted into the first pin hole and the second pin hole, or the pin can be withdrawn from the first pin hole and the second pin hole.

[0013] In some embodiments of this utility model, a side plate is provided on the upper surface of the main beam of the catwalk, the side plate is arranged along the length direction of the main beam of the catwalk, and the second pin hole is opened in the side plate.

[0014] In some embodiments of this utility model, one end of the pin is provided with a connecting chain, and the other end of the connecting chain is fixedly connected to the main beam of the walkway or the steel grating.

[0022] Figures 1 to 7This is a schematic diagram of one embodiment of a steel grating device capable of being opened or closed according to this utility model. A steel grating device capable of being opened or closed according to this embodiment (for ease of explanation, it will sometimes be referred to simply as "steel grating device" below).

[0023] Reference Figures 1 to 7 A steel grating device capable of being opened or closed, applied to a steel structure walkway, includes two main walkway beams 100, a crossbeam 200, a middle beam 300, and a steel grating 400. The two main walkway beams 100 are arranged parallel to each other and spaced apart, and the crossbeam 200 connects the two main walkway beams 100. To enhance the structural strength of the steel grating device, in this embodiment, both the crossbeam 200 and the two main walkway beams 100 are I-beams. The crossbeam 200 is arranged along a direction perpendicular to the two main walkway beams 100 and is welded and fixed together with them. The middle beam 300 is disposed between the two main walkway beams 100 and is welded and fixed together with the crossbeam 200. The middle beam 300 is arranged parallel to and spaced apart from the two main walkway beams 100. A steel grating 400 is arranged between the intermediate beam 300 and one of the main beams 100 of the walkway. The side of the steel grating 400 closest to the intermediate beam 300 is designated as the first side, and the side of the steel grating 400 closest to the main beam 100 is designated as the second side. The first side of the steel grating 400 is rotatably connected to the intermediate beam 300. The steel grating 400 can rotate upwards or downwards relative to the intermediate beam 300. When the steel grating 400 is rotated downwards to a horizontal position, the second side of the steel grating 400 can rest on the adjacent main beam 100. In this embodiment, when the steel grating 400 is rotated downwards to a horizontal position, the main beam 100 closest to the second side of the steel grating 400 is the adjacent main beam 100. A locking structure is provided between the second side of the steel grating 400 and the adjacent main beam 100 of the walkway. The locking structure can lock the steel grating 400 and the main beam 100 together, or the locking structure can release the locking connection between the steel grating 400 and the main beam 100.

[0024] By adopting the above structure, when workers need to open the steel grating 400, they only need to unlock the locking connection between the steel grating 400 and the main beam 100 of the walkway through the locking structure. At this time, the steel grating 400 can rotate upward relative to the middle beam 300 of the walkway to open the steel structure walkway. When the steel grating 400 rotates downward relative to the middle beam 300 of the walkway and lowers so that the second side of the steel grating 400 rests on the adjacent main beam 100 of the walkway, the locking structure can lock the second side of the steel grating 400 and the main beam 100 of the walkway together to close the steel structure walkway. At this time, the first side of the steel grating 400 is connected to the middle beam 300 of the walkway, and the second side of the steel grating 400 is locked to the adjacent main beam 100 of the walkway. Thus, the steel grating 400 is firmly fixed to the main beam 100 and the middle beam 300 of the walkway, effectively preventing the steel grating 400 from being blown off or accidentally falling off the steel structure walkway, ensuring the safety of personnel walking, and is simple and convenient to operate.

[0025] Reference Figure 1 , Figure 2 and Figure 3 In some embodiments of this utility model, the intermediate beam 300 of the walkway is positioned in the middle between the two main beams 100 of the walkway. There are two steel gratings 400, one positioned between the intermediate beam 300 and one of the main beams 100, and the other positioned between the intermediate beam 300 and the other main beam 100. By adopting this structure, the width of the steel structure walkway can be increased to facilitate worker movement. Furthermore, workers can freely choose to open either steel grating 400 while the other grating remains horizontal, making construction more convenient.

[0026] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5In some embodiments of this utility model, a square tube 310 is provided on the upper part of the crosswalk center beam 300. In this embodiment, the square tube 310 is a galvanized square tube or a stainless steel tube. Other materials can also be selected for the square tube 310 according to actual needs, and it is not limited to the aforementioned galvanized square tube or stainless steel tube. The square tube 310 is arranged along the length direction of the crosswalk center beam 300. A hinge 320 is provided between the first side of the steel grating plate 400 and the square tube 310. The first connecting piece 321 of the hinge 320 is connected to the first side of the steel grating plate 400, and the second connecting piece 322 of the hinge 320 is connected to the square tube 310. Further, a connecting piece 410 is welded to the upper surface of the first side of the steel grating plate 400. The first connecting piece 321 is welded to the connecting piece 410, and the second connecting piece 322 is welded to the upper surface of the square tube 310. The above structure facilitates the production and processing of the steel grating 400 and the intermediate beam 300 of the walkway, and makes the rotational connection between the steel grating 400 and the intermediate beam 300 of the walkway more secure and less prone to falling off or separating, thereby improving the safety performance of the steel grating device in this embodiment.

[0027] In some embodiments of this utility model, two hinges 320 are provided between the first side of the steel grating 400 and the square tube 310, and the two hinges 320 are arranged at intervals along the length direction of the steel grating 400. In this embodiment, the steel grating 400 is rotatably connected to the square tube 310 by two hinges 320, which can further enhance the reliability of the rotatable connection between the steel grating 400 and the crosswalk intermediate beam 300.

[0028] Reference Figure 1 , Figure 2 , Figure 3 and Figure 7 In some embodiments of this utility model, the locking structure includes a pin 500, a first pin hole 510, and a second pin hole 520. The first pin hole 510 is located on the second side of the steel grating 400, and the second pin hole 520 is located on the main beam of the walkway 100. When the steel grating 400 is rotated downwards and its second side rests on the main beam of the walkway 100, the first pin hole 510 and the second pin hole 520 are aligned, and the pin 500 can be inserted into the first pin hole 510 and the second pin hole 520. At this time, the pin 500 locks the second side of the steel grating 400 and the main beam of the walkway 100 together, and the steel grating 400 cannot be rotated upwards relative to the middle beam of the walkway 300 through the hinge 320. Alternatively, the pin 500 can be withdrawn from the first pin hole 510 and the second pin hole 520, at which point the locking connection between the second side of the steel grating 400 and the main beam 100 of the walkway is released, and the steel grating 400 can be rotated and raised relative to the middle beam 300 of the walkway through the hinge 320, thereby opening the steel structure walkway.

[0029] Reference Figure 1, Figure 2 , Figure 3 , Figure 6 and Figure 7 A side plate 110 is provided on the upper surface of the main beam 100 of the walkway, and the side plate 110 is welded and fixed to the main beam 100. The side plate 110 is arranged along the length direction of the main beam 100, and a second pin hole 520 is formed in the side plate 110. By adopting the above-mentioned arrangement, it is not only convenient to manufacture the second pin hole 520, but the side plate 110 can also serve as a protective plate or a kick plate, which helps to improve the safety performance of the steel grating device in this embodiment.

[0030] Reference Figure 1 , Figure 3 and Figure 7 In some embodiments of this utility model, one end of the pin 500 is provided with a connecting chain 530, and the other end of the connecting chain 530 is fixedly connected to the main beam 100 of the walkway or the steel grating 400. In this embodiment, the connecting chain 530 is an iron chain or a stainless steel chain. The pin 500 is fixedly connected to the main beam 100 of the walkway or the steel grating 400 by the connecting chain 530, which can effectively prevent the pin 500 from accidentally falling off or being lost, thereby improving safety performance.

[0031] Reference Figure 1 , Figure 2 , Figure 4 and Figure 6 In some embodiments of this utility model, a limiting structure is provided between the second side of the steel grating 400 and the adjacent main beam 100 of the walkway. This limiting structure restricts the movement of the second side of the steel grating 400 along the length of the main beam 100. Specifically, the limiting structure includes a positioning pin 600 fixedly disposed on the upper surface of the main beam 100. The positioning pin 600 is arranged vertically. When the steel grating 400 rotates downwards and its second side rests on the main beam 100, the positioning pin 600 is inserted into the grating hole of the steel grating 400. By adopting the above structure, the positioning pin 600 can engage with the grating hole of the steel grating 400, thereby restricting the movement and offset of the second side of the steel grating 400 along the length of the main beam 100. This facilitates the alignment of the first pin hole 510 and the second pin hole 520, and also makes the connection between the steel grating 400 and the main beam 100 more secure and reliable.

[0032] In some embodiments of this utility model, the limiting structure includes a plurality of positioning pins 600 fixedly disposed on the upper surface of the main beam 100 of the walkway, the plurality of positioning pins 600 being arranged sequentially and evenly at intervals along the length direction of the main beam 100 of the walkway. When the steel grating 400 is rotated downward and its second side rests on the main beam 100 of the walkway, the plurality of positioning pins 600 are inserted one-to-one into the plurality of grating holes of the steel grating 400, so that the limiting structure can better restrict the movement or offset of the second side of the steel grating 400 along the length direction of the main beam 100 of the walkway.

[0033] Although embodiments of this implementation have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this implementation, the scope of which is defined by the claims and their equivalents.
