Description

Technical Field

[0001] The utility model belongs to the field of bridge construction, and particularly relates to a suspended decoration construction platform. Background Art

[0002] For the design of long-span bridges, the lower edges of the sidewalks on both sides often adopt an inverted arc shape to achieve the harmonious unity of aesthetics and structure. However, when the height of the bridge cross-section is relatively significant, the external decoration construction under the sidewalk becomes particularly difficult. Traditional hanging basket-type maintenance hanging scaffolds often fall short when dealing with such height problems and are difficult to meet the precise requirements of construction. In addition, although bridge inspection vehicles play a role in certain maintenance tasks, their limited construction area poses a significant challenge to the complex and delicate lofting of external decoration keels and the smooth connection of processes. This not only limits the construction flexibility but also leads to a reduction in construction efficiency. Facing this problem, if necessary modifications are considered to existing bridge inspection vehicles or hanging basket-type maintenance hanging scaffolds to meet higher construction standards, it will undoubtedly involve a considerable cost investment. Such modifications not only include the design update of equipment but may also involve additional expenses in aspects such as materials, labor, and subsequent maintenance.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present utility model. In addition, all the connection / connection relationships involved in the patent do not simply refer to the direct connection of components, but refer to the more optimal connection structure that can be formed by adding or reducing connection accessories according to the specific implementation situation.

[0050] For a long-span bridge, the lower part of the sidewalks on both sides of the bridge body 1 usually adopts an inverted arc-shaped structure. The cross-section of the bridge body 1 is relatively high, and the construction on both sides of the bridge body 1 is difficult, and the traditional maintenance platform cannot meet the requirements. A suspended decoration construction platform of the present utility model is arranged under the sidewalks on both sides of the bridge body 1. Through this construction platform, the needs of large-section construction at the bottom of the sidewalk can be met, and the construction of the bottom of the sidewalk, the side and the bottom of the bridge body 1 can be completed simultaneously, providing a large range of construction work surfaces and facilitating the cooperation of multiple people.

[0051] Refer to Figures 1-10, A suspended decoration construction platform, including a truss 2, the upper surface of the truss 2 is the construction platform, located at the bottom of the sidewalk on the side of the bridge body 1, and the truss 2 is provided with a first connector 201 and a second connector 202; one end of the first connector 201 is connected to the bridge body 1, and the other end is connected to the truss 2, and the length of the first connector 201 is adjustable, used to hoist the truss 2 to a predetermined position; one end of the second connector 202 is connected to the bridge body 1, and the other end is connected to the truss 2, used to suspend and support the truss 2 at a predetermined position. The truss 2 has high load-bearing capacity, high stability, durability, earthquake resistance, etc., making it an indispensable important part in modern architecture and engineering. In the present utility model, after the truss 2 is installed on the bridge deck, it is connected to both ends of the truss 2 through the first connector 201, and the truss 2 is suspended from the bridge deck to a predetermined position. Among them, the length of the first connector 201 is adjustable, and the height of the truss 2 can be adjusted at any time by adjusting the length of the first connector 201 to meet the construction requirements. When the truss 2 is suspended to a predetermined position, the truss 2 is fixedly connected to the bridge body 1 through the second connector 202, and the truss 2 can be stably suspended at the predetermined position. Among them, the length of the second connector 202 is fixed, and the length can be determined in advance according to the actual working conditions. The actual installation state can be referred to Figures 5-8 .

[0052] It should be noted that after the truss 2 is in the suspended position, workers can carry out construction work on the bridge body 1 on the construction platform on the upper surface of the truss 2. The second connector 202 is preferably connected to the four corners of the construction platform surface of the truss 2, so that the four corners of the construction platform are subjected to uniform tensile force, ensuring the stability of the construction platform during the construction process. In addition, since the first connector 201 only needs to hoist the installed truss 2 to a predetermined position, the first connector 201 can have only two, respectively connected to both ends of the truss 2, and the strength of the first connector 201 can be a steel rope with a lower strength. And the second connector 202 not only needs to bear the weight of the truss 2, but also subsequent scaffolds, materials, multiple workers, etc. built on the construction platform. Obviously, the second connector 202 needs to have sufficient mechanical strength, preferably a thicker steel rope, to meet the load-bearing requirements.

[0053] Refer to Figure 3 , 9, 10. In some embodiments, first lifting lugs 204 are provided at both ends of the truss 2. The first lifting lugs 204 are fixedly connected to the first connecting member 201 and the second connecting member 202. The first connecting member 201 and the second connecting member 202 are connected to the bridge body 1 through the anchor members 11. A length adjusting device 12 is provided between the first connecting member 201 and the anchor member 11 for adjusting the length of the first connecting member 201. It should be noted that during the use of the construction platform, the first connecting member 201 needs to be removed, and only the second connection bears the weight of the entire truss 2. Specifically, there are at least four first lifting lugs 204, which are respectively located on the opposite sides at both ends of the truss 2, that is, at the four corners of the construction platform. One end of the second connecting member 202 is connected to the first lifting lug 204, and the other end is connected to the anchor member 11 to ensure the stability of the construction platform. Among them, the anchor member 11 is preferably located at positions such as the anti-collision piers on the surface of the bridge body 1.

[0054] Referring to Figure 1 , 5 , further, the anchor member 11 includes a first anchor member 111 located at the edge of the bridge body 1 and a second anchor member 112 located on the bridge body 1. The line connecting the first anchor member 111 and the second anchor member 112 is perpendicular to the edge of the bridge body 1. The first connecting member 201 is fixedly connected to the second anchor member 112 and slidably connected to the first anchor member 111. The length adjusting device 12 is located between the first anchor member 111 and the second anchor member 112. The second connecting member 202 is fixedly connected to the first anchor member 111 and the second anchor member 112 respectively. It can be understood that first anchor members 111 and second anchor members 112 are provided at the positions corresponding to the bridge deck at both ends of the truss 2. Among them, when installing and lowering the truss 2, one end of the first connecting member 201 is fixed to the second anchor member 112, and the length adjusting device is adjusted. The first connecting member 201 acts on the first anchor member 111 through the sliding connection to adjust the length of the first connecting member 201. Among them, the first connecting member 201 and the first anchor member 111 are slidably connected through a pulley assembly 13 provided, and the pulley assembly 13 can make the length adjusting device 12 more labor-saving during the adjustment process. Preferably, the length adjusting device 12 is an electric chain hoist device.

[0055] In some embodiments, referring to Figure 2, at least one second lifting lug 205 may be provided between the two ends of the truss 2. The second lifting lug 205 is connected to the bridge body 1 through a third connecting member 203 to enhance the bearing capacity of the construction platform. That is to say, on the construction surface between the two ends of the truss 2, multiple second lifting lugs 205 can be provided. It should be noted that the first lifting lug 204 is an installation lifting lug for carrying the operation platform, and the second lifting lug 205 is a working lifting lug. The working lifting lug is connected to the bridge body 1 through a third connecting member 203 to enhance the bearing capacity of the operation platform. In addition, the working lifting lug is also used to support and suspend construction personnel or equipment to facilitate operations at high altitudes or specific positions.

[0056] In some embodiments, referring to Figure 9 , 10 , the truss 2 includes an upper chord 2061, a lower chord 2071, web members 208, and diagonal braces 209; there are at least two upper chords 2061, which are fixedly connected into an upper chord surface 206 through a first cross link 2062; there are at least two lower chords 2071, which are fixedly connected into a lower chord surface 207 through a second cross link 2072; the upper chord surface 206 and the lower chord surface 207 are arranged in parallel, and the web members 208 are vertically connected between the upper chord 2061 and the lower chord 2071 at opposite positions; the diagonal braces 209 are obliquely arranged between the upper chords 2061 and the lower chords 2071 at different positions. It can be understood that the truss 2 is mainly strengthened integrally by the diagonal braces 209 obliquely arranged between the upper chords 2061 and the lower chords 2071. That is to say, the diagonal braces 209 are cross arranged inside the truss 2, forming several triangular structures inside the truss 2. Due to the stable structure of the triangle, the truss 2 has extremely strong bearing capacity. Among them, the chord members, the lower chord 2071, the web members 208, the first cross link 2062, the second cross link 2072, and the diagonal braces 209 are all made of steel structures and are fixed by bolting or welding.

[0057] Furthermore, referring to Figure 9 , 10, springboards 210 are laid on both the upper chord surface 206 and the lower chord surface 207; after the springboards 210 are laid on the upper chord surface 206, a construction platform is formed; after the springboards 210 are laid on the lower chord surface 207, a storage platform 211 is formed for storing construction materials. After the springboards 210 are laid, a construction platform is formed above the truss 2. In addition, below the construction platform, that is, on the lower chord surface 207, a storage platform 211 is formed, which can be used to store some light construction materials, reduce the frequency of back-and-forth handling of materials, and improve construction efficiency. A manhole 212 is provided on the construction platform for accessing the storage platform 211. Workers can freely shuttle between the construction platform and the storage platform 211 through the manhole 212 to obtain construction materials. Specifically, the manhole 212 can be a through hole provided on the springboard 210, or a passage for the manhole 212 can be formed by removing the springboard 210.

[0058] In some embodiments, the storage platform 211 can also be used as a construction platform, that is, workers can construct the sides and bottom edges of the bridge body 1 on the storage platform 211.

[0059] In some embodiments, referring to FIGS. 1 and 2, since it is high-altitude operation and the construction conditions are relatively dangerous, in order to improve the safety during construction, guardrails 214 are provided on both sides along the extending direction of the truss 2 above the construction platform. That is to say, the guardrails 214 enclose the entire construction platform, so that when workers are working on the construction platform, the safety of the workers can be protected.

[0060] On the construction platform, scaffolding will be flexibly erected according to the specific internal structure of the bridge body 1 to make up for the height difference between the construction platform and the construction site. The operation platform may shake during use, which poses a certain safety hazard to the erected scaffolding. Therefore, referring to FIGS. 9 and 10, a plurality of positioning structures 213 are provided on the construction platform, and scaffolding is erected on the construction platform, and the scaffolding is positioned by the positioning structures 213. The scaffolding is positioned and fixed by the positioning structures 213, so that even if the construction platform shakes during use, the scaffolding will be firmly fixed on the platform, eliminating the risk of tipping over.

[0061] The above is a specific description of the preferred embodiments of the present invention, but the present invention is not limited to the above embodiments. Those skilled in the art can make various equivalent deformations or substitutions without departing from the spirit of the present invention, and these equivalent deformations or substitutions are all included in the scope defined by the claims of this application.
