Description

Technical Field

[0001] This utility model relates to the field of bridge construction technology, and in particular to a prefabricated anti-fall platform for bridge girder construction. Background Technology

[0002] In the field of bridge construction, the cap beam, as the core load-bearing structure connecting the piers and the superstructure, directly determines the overall stability and service life of the bridge through its construction quality and safety. With the rapid advancement of my country's transportation infrastructure construction, a large number of bridges require the construction of cap beams above existing roads. In such construction scenarios, the cap beam supports need to cross existing roads, with continuous pedestrian and vehicle traffic below. The risk of falls from heights during construction has become a core challenge for safety management.

[0003] Currently, steel pipe Bailey bridges are commonly used as the support system for road-crossing girder construction. Due to their strong load-bearing capacity and ease of assembly and disassembly, these bridges can effectively meet the spatial requirements of road-crossing construction. However, significant technical shortcomings remain in the fall protection at the base of the support structure. Existing fall protection solutions mainly fall into two categories: one is the traditional method of using full-span scaffolding combined with safety nets. This method requires occupying road space below, leading to traffic disruptions or restrictions, which contradicts the requirement of "minimizing the impact on traffic" in road-crossing construction. The other method uses a protective platform, which involves fixing steel plates or safety nets to the bottom of the Bailey bridge. However, this method suffers from the problem of a fixed platform position, making it impossible to adjust the lateral or longitudinal position according to the girder construction sequence.

[0022] The construction of the cap beam is a crucial step in the substructure construction of a bridge. It primarily connects piers or columns and bears the load of the superstructure beam. Before construction, foundation treatment and the erection of cap beam supports must be completed. Commonly used cap beam supports include steel pipe Bailey bridges, full-span scaffolding, and clamp-type supports. For cap beam construction involving roads, steel pipe Bailey bridges are generally used. However, to ensure passage underneath, a prefabricated fall arrest platform is one of the key aspects of ensuring safe cap beam construction.

[0023] like Figure 1 As shown in the figure, an embodiment of the present invention relates to a prefabricated anti-fall platform for cap beam construction, which is used to fix the bottom of the cap beam support to reduce the risk of falling objects injuring pedestrians during the cap beam construction process.

[0024] Combination Figure 1 and Figure 2 The prefabricated anti-fall platform for the construction of the cap beam includes a platform body 100 and a first support component 200. The first support component 200 is connected to the platform body 100. The first support component 200 includes a first channel steel 210 and a second channel steel 220 arranged parallel to and spaced apart from the first channel steel 210. A first gap 230 is formed between the first channel steel 210 and the second channel steel 220. Both the first channel steel 210 and the second channel steel 220 extend along a first direction.

[0025] Specifically, the first support component 200 is fixedly connected to the platform body 100. More specifically, the first channel steel 210 and the second channel steel 220 are both fixed to the upper side of the platform body 100. The first channel steel 210 and / or the second channel steel 220 can be fixed to the platform body 100 by welding or by means of fasteners such as bolts. Furthermore, both the first channel steel 210 and the second channel steel 220 extend along a first direction; in other words, the length direction of the first channel steel 210 and the length direction of the second channel steel 220 are both the first direction, which is substantially parallel to the horizontal plane. Further, the first channel steel 210 and the second channel steel 220 are arranged side-by-side and spaced apart along a second direction to form a first gap 230 between them. The second direction is perpendicular to the first direction and is also substantially parallel to the horizontal plane. It is understood that the first gap 230 formed between the first channel steel 210 and the second channel steel 220 also extends along the first direction.

[0026] It should be noted that a second support component 400 is provided at the bottom of the cap beam support. Specifically, the cap beam support is a steel pipe Bailey bridge, and the second support component 400 is installed on the Bailey bridge. The second support component 400 includes a third channel steel 410 and a fourth channel steel 420 arranged parallel to and spaced apart from the third channel steel 410. A second gap 430 is formed between the third channel steel 410 and the fourth channel steel 420, and both the third channel steel 410 and the fourth channel steel 420 extend along a second direction.

[0027] Specifically, the second support assembly 400 is fixedly connected to the Bailey beam. More specifically, both the third channel steel 410 and the fourth channel steel 420 are fixed to the Bailey beam. The third channel steel 410 and / or the fourth channel steel 420 can be fixed to the Bailey beam by welding or by means of fasteners such as bolts. Furthermore, both the third channel steel 410 and the fourth channel steel 420 extend along a second direction; in other words, the length direction of both the third channel steel 410 and the fourth channel steel 420 is the second direction. Further, the third channel steel 410 and the fourth channel steel 420 are arranged side-by-side and spaced apart along a first direction to form a second gap 430 between them. It is understood that the second gap 430 formed between the third channel steel 410 and the fourth channel steel 420 also extends along the second direction.

[0028] The prefabricated fall arresting platform for girder construction is used to be installed below the second support component 400 so that the first support component 200 is located below the second support component 400; the prefabricated fall arresting platform for girder construction also includes a connecting component 300, which passes through the first gap 230 and the second gap 430 and connects the first support component 200 and the second support component 400, and the first support component 200 can move relative to the connecting component 300 in a first direction and can move relative to the second support component 400 in a second direction.

[0029] It is understood that the first gap 230 extends along the first direction, and the second gap 430 extends along the second direction. Before connecting the first support component 200 and the second support component 400 using the connecting component 300, the position of the prefabricated fall arrest platform for the cap beam construction can be adjusted along the first and / or second directions as required, ensuring that a portion of the first gap 230 is aligned with a portion of the second gap 430. Then, the connecting component 300 is inserted into the first gap 230 and the second gap 430 to connect the first support component 200 and the second support component 400. Of course, after connecting the first support component 200 and the second support component 400 using the connecting component 300, the position of the prefabricated fall arrest platform for the cap beam construction can also be adjusted along the first and / or second directions.

[0030] In some embodiments, the slots of the first channel steel 210 and the second channel steel 220 are arranged opposite to each other. Additionally, the slots of the third channel steel 410 and the fourth channel steel 420 are also arranged opposite to each other.

[0031] In some embodiments, the connecting assembly 300 includes a screw 310, a first nut, and a second nut 320. The screw 310 passes through a first gap 230 and a second gap 430. The first nut is sleeved on the screw 310 and abuts against the side of the first support assembly 200 away from the second support assembly 400. The second nut 320 is sleeved on the screw 310 and abuts against the side of the second support assembly 400 away from the first support assembly 200.

[0032] Understandably, the aforementioned connecting component 300 enables the connection between the first support component 200 and the second support component 400. Furthermore, it allows for adjustment of the installation height of the prefabricated fall arrest platform for the girder construction as required. It should be noted that to improve the safety of girder construction, multiple prefabricated fall arrest platforms can be installed to increase the protective area. Therefore, by making the height of each prefabricated fall arrest platform adjustable, each platform can be positioned at the same height and against each other, avoiding the risk of objects falling through gaps between adjacent platforms.

[0033] In some embodiments, there are multiple first support components 200, all of which are connected to the platform body 100 and spaced apart along a second direction. Each first support component 200 is connected to a second support component 400 via a different connecting component 300. This improves the uniformity of stress distribution on the prefabricated anti-fall platform for girder construction.

[0034] In other embodiments, there are multiple second support components 400, all connected to the cap beam support and spaced apart along the first direction, and each second support component 400 is connected to the first support component 200 via a different connecting component 300. This further improves the stress uniformity of the prefabricated anti-fall platform for cap beam construction.

[0035] Combination Figure 1 and Figure 3 In some embodiments, the platform body 100 includes a frame 110, supporting steel bars 120 disposed on the frame 110, and a fall arrestor plate 130 disposed on the supporting steel bars 120. The height of the frame 110 is higher than the height of the fall arrestor plate 130, so the frame 110 forms a barrier structure to prevent items on the fall arrestor plate 130 from falling from the side of the fall arrestor plate 130.

[0036] Furthermore, there are multiple supporting steel bars 120, which are arranged side by side and spaced apart, and together support the fall arrestor plate 130.

[0037] Furthermore, a kick plate 140 is provided on the platform body 100, which is used to prevent items on the fall arrestor 130 from falling.

[0038] Furthermore, the platform body 100 is provided with lifting holes 101, and the prefabricated anti-fall platform for the cap beam construction can be lifted by a crane and reach the predetermined position.
