[0054] 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.
[0055] like Figures 1-5 As shown, this embodiment provides a safety fence for construction projects, including a fence body. The fence body includes a frame formed by a top plate 1, a bottom plate 2, a first connecting post 3, and a second connecting post 4. A plurality of equally spaced uprights 5 are arranged within the frame. The first connecting post 3 and the second connecting post 4 each have a plurality of fixing holes. It also includes connectors 6 that can be selectively connected to preset positions of the first connecting post 3 or the second connecting post 4, and support legs 7 that are detachably connected to the bottom plate 2. It further includes plug-in connectors 8, which are used to connect two vertically distributed connectors 6 in adjacent frames.
[0056] Among them, in the main body of the fence, such as Figure 1 and Figure 2As shown, the first connecting post 3 and the second connecting post 4 have the same structure, both being hollow posts. The first connecting post 3 is provided with several sets of vertically distributed fixing holes, including two opposing first fixing holes 31, two opposing second fixing holes 32, two opposing third fixing holes 33, and two opposing fourth fixing holes 34. Specifically, the two first fixing holes 31 and the two third fixing holes 33 are located on the same horizontal plane, and the lines connecting the two first fixing holes 31 and the two third fixing holes 33 are perpendicular to each other and pass through the central axis of the first connecting post 3. The two second fixing holes 32 and the two fourth fixing holes 34 are located on the same horizontal plane, and the lines connecting the two second fixing holes 32 and the two fourth fixing holes 34 are perpendicular to each other and pass through the central axis of the first connecting post 3; furthermore, the angle between the lines connecting the two first fixing holes 31 and the two third fixing holes 33 is 45°. The design of the fixing holes on the first connecting post 3 and the second connecting post 4 allows for eight installation positions for the connector, which can meet the needs of fence installation and connection in most cases.
[0057] In the main body of the fence, the base plate 2 has several equally spaced first through holes 21. The support leg 7 is a convex plate, and its protruding part forms a connecting platform. The connecting platform has a second through hole 71. By using bolts passing through one of the first through holes 21 and the second through hole 71 in the base plate 2, the base plate 2 can be fixedly connected to the support leg 7. The part of the support leg 7 that contacts the ground also has a third through hole 72. By using anchor rods or anchor bolts passing through the third through hole 72, the support leg 7 can be fixed to the ground. In practical applications, at least two sets of support legs 7 are arranged, and the two sets of support legs 7 are symmetrical about the vertical centerline of the main body of the fence.
[0058] In this embodiment, as Figures 1-4 As shown, the connector 6 includes a sleeve 61 fitted onto the first connecting post 3 or the second connecting post 4 and a connecting cylinder 62 for connecting adjacent fence bodies. A connecting plate 63 is fixedly connected between the sleeve 61 and the connecting cylinder 62.
[0059] Specifically, sleeve 61 has two opposing fourth through holes 611 and two opposing fifth through holes 612. The line connecting the two fourth through holes 611 and the line connecting the two fifth through holes 612 are perpendicular to each other and pass through the central axis of sleeve 61. Connecting cylinder 62 has two opposing sixth through holes 621 and two opposing seventh through holes 622. The line connecting the two sixth through holes 621 and the line connecting the two seventh through holes 622 are perpendicular to each other and pass through the central axis of connecting cylinder 62. Sleeve 61 in connecting member 6 is fitted onto the first connecting post 3 or the second connecting post 4. When the fourth through hole 611 coincides with the first fixing hole 31 and the fifth through hole 612 coincides with the third fixing hole 33, bolts are used to pass through the corresponding fourth through holes 611 and the first fixing hole 31 to fix connecting member 6 to the first connecting post 3 or the second connecting post 4. When it is necessary to extend the fence in the length direction, remove the bolts, and then rotate connector 6 180° to install the adjacent fence body to extend the fence in the length direction.
[0060] In this embodiment, the connector 8 is used to connect two vertically distributed connecting cylinders 62 in adjacent frames.
[0061] Specifically, the connector 8 includes a top cap 81 and a tube 82 fixedly connected to each other, with the top cap 81 located at the top end of the tube 82. The tube 82 has two sets of vertically distributed socket groups, each socket group including several equally spaced sockets 821. In this embodiment, each socket group includes eight equally spaced sockets 821.
[0062] In this embodiment, diagonal bracing 9 is also provided to maintain the overall stability of the fence after it extends in the row length or height direction. For example... Figure 13 and Figure 14 As shown, the two ends of the diagonal brace 9 are each provided with an eighth through hole 91. Different lengths of diagonal braces 9 can be used for auxiliary support depending on the height of the fence. The diagonal braces 9 can be installed on one side of the fence or on both sides. The bottom end of the diagonal brace 9 is connected to the bottom connecting plate 10, which is detachably connected to the ground. The bottom connecting plate 10 is a flat plate with a ninth through hole 101 for fixing to the ground. A bottom connecting lug 102 is fixed to the upper end of the bottom connecting plate for connecting to the bottom end of the diagonal brace 9. The top end of the diagonal brace 9 is connected to the top connecting plate 11, which is detachably connected to the connecting cylinder 62. The top connecting plate 11 is an arc plate adapted to the outer wall of the connecting cylinder 62, with a tenth through hole 111 for connecting to the connecting cylinder 62. A top connecting lug 112 is fixed to the outer side of the top connecting plate 11 for connecting to the top end of the diagonal brace 9.
[0063] The construction safety fence provided in this embodiment can extend in a straight line in the length direction, and can also form a preset angle between two adjacent fence bodies during the extension, such as 135°, 90°, etc.; it can also extend in the height direction.
[0064] The fence body in this embodiment can be used independently. When used independently, the sleeve 61 in the connector 6 is fixed to the first connecting post 3 and the second connecting post 4 by bolts. At the same time, each connecting sleeve 62 is located between the first connecting post 3 and the adjacent upright post 5, or between the second connecting post 4 and the adjacent upright post 5.
[0065] like Figures 5-8 As shown, when multiple fence bodies are used together and extended linearly along their length, the bolts are loosened, and some connecting parts 6 are rotated 180°. For example, the third and seventh connecting parts 6 on the second connecting post 4 in the left fence body are rotated 180°, and the second and sixth connecting parts on the first connecting post 3 in the second fence body are rotated 180°. At this time, the adjacent fence bodies are on the same straight line. Then, the connecting cylinders 62 of the two adjacent connecting parts are overlapped, and the inserts 8 are inserted through them. Bolts are then passed through the corresponding holes on the corresponding connecting cylinders 62 and inserts 8 and fixed with bolts. When multiple fence bodies are extended and connected, the connection method is similar, thus achieving a linear extension of the fence, which is suitable for construction projects where length is required. It is worth noting that each fence body is provided with supporting legs 7 at its bottom.
[0066] like Figures 9-11 As shown, when the fence needs to be extended and make a certain degree of turning or change of direction, for example, when two adjacent fence bodies are at a 135° angle during extension, the bolts are loosened, and some connecting parts 6 are rotated 180°. For example, the third and seventh connecting parts 6 on the second connecting post 4 in the left fence body are rotated 180°, and the second and sixth connecting parts on the first connecting post 3 in the second fence body are rotated 180°. At this time, the adjacent fence bodies are at a 135° angle. Then, the connecting cylinders 62 of the two adjacent connecting parts are overlapped, and the inserts 8 are inserted through them. Bolts are passed through the corresponding holes on the corresponding connecting cylinders 62 and inserts 8 and fixed with bolts. When multiple fences are extended and connected, the connection method is similar, thus realizing the extension of the fence in a bending type, which is suitable for the situation in construction projects where the fence layout requires bending. It is worth noting that each fence body is provided with supporting legs 7 at the bottom.
[0067] like Figure 12As shown, when it is necessary to extend the fence in the height direction, the top connector 6 in the lower fence body is rotated 90°, and the bottom connector in the upper fence body is rotated 270°. Then, the connecting cylinders 62 of the two adjacent connectors are aligned vertically, and a plug-in 8 is inserted through them. Bolts are then passed through the corresponding holes on the connecting cylinders 62 and plug-in 8 and fixed with bolts. This achieves the extension of the fence in the height direction.
[0068] In the above-mentioned types of extended fences, in order to maintain the overall stability of the fence, diagonal bracing rods 9 of corresponding length are used for auxiliary support; diagonal bracing rods 9 can be installed on one side of the fence, or diagonal bracing rods 9 can be installed on both sides of the fence.
[0069] The construction safety fence provided in this embodiment features a detachable installation structure design for the fence body, connectors 6, and plug-in connectors 8, enabling flexible extension and connection of the fence in either the length or height direction. Connectors 6 are installed on the corresponding fixing holes of the first connecting post 3 or the second connecting post 4. By rotating connectors 6 and connecting adjacent connectors 6 using plug-in connectors 8, the fence can be extended in a straight or bent direction. The construction safety fence provided in this embodiment can achieve straight and bent extension in the length direction, as well as extension in the height direction, making it suitable for various construction scenarios, including areas requiring complex fence layouts. The multi-angle installation design of connectors 6 allows for flexible connection between fence bodies without the need for additional fixing feet or flipping the fence, simplifying the installation process. The structural design of connectors 6 and plug-in connectors 8 makes the installation and disassembly of the fence easier and faster.
[0070] The supporting legs 7 are detachably connected to the base plate 2 of the fence body and can be fixed to the ground to maintain the overall stability of the fence; at the same time, diagonal braces 9 are provided to enhance the overall stability of the fence. The design of the supporting legs and diagonal braces provides stability to the fence after it is extended, preventing the fence from tilting or collapsing during construction and improving safety.
[0071] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
