Description

Technical Field

[0001] This utility model relates to a protective device, specifically a non-welded, easily installable and detachable temporary protective device for trestle bridge decks, mainly used for temporary protection during the construction of trestle bridge decks, and belongs to the field of building construction protection technology. Background Technology

[0002] As is well known, temporary protective devices during bridge deck construction serve multiple purposes, including ensuring site safety, preventing accidents, and protecting construction personnel and equipment. Their aim is not only to prevent accidents but also to ensure the smooth progress of construction and safeguard the surrounding environment and public safety.

[0003] For the Mingzhen Pier, Changyaoshan Pier, and Huzhi Bridge, whose bridge decks are more than 3 meters above the ground, the construction of the bridge deck system is considered high-altitude work. The construction period from the completion of the superstructure hoisting to the paving of the bridge deck is about 90 days. In order to ensure the safety of high-altitude construction, and considering the characteristics of the superstructure of the pier, temporary protective devices are often required during construction.

[0004] Temporary protective devices are often erected temporarily during bridge construction. This temporary nature in their design can lead to incomplete considerations, such as a lack of adaptability, failure to account for the needs of different construction stages, or the inability to flexibly adjust installation and removal based on bridge structure and environmental conditions. This can hinder construction progress. Some construction units may neglect the inspection and timely maintenance of temporary protective devices, resulting in potential safety hazards. On bridge decks, the absence or lack of clearly visible protective devices can easily lead to passing vehicles or pedestrians being unaware of the dangers in the construction area, causing pedestrians to mix with construction areas and potentially resulting in accidents.

[0005] Traditional temporary protection methods for steel bridges involve welding connectors onto the bridge deck and then specifying protective structures on these connectors. This extensive welding on the bridge deck leads to severe material damage, high labor costs, inconvenient installation and dismantling, and low material recycling rates. When using traditional formwork structures for protection, there is a significant fire hazard during dry seasons, corrosion in rainy or humid environments, or slippage due to ice and snow in cold regions, causing failure. In short, it is often very inconvenient.

[0006] Therefore, the key to solving the above-mentioned technical problems lies in developing a non-welded, easily installable and disassembled temporary protection device for trestle bridges that is highly practical and reliable. Summary of the Invention

[0007] In view of the many defects and shortcomings existing in the above-mentioned background technology, this utility model has made improvements and innovations, aiming to provide a temporary protective device for bridge decks that is simple in construction, novel and reasonable in design, and adopts a non-welded, easily detachable steel trestle. Its components are manufactured in the factory, installation is quick, labor costs are reduced, welding connections are not required, material damage is low, and the reuse rate is high. The use of a detachable protective structure in bridge deck construction can improve construction safety, increase efficiency, reduce costs, and has high flexibility and adaptability. While providing good protection, this protective structure not only meets the safety requirements during construction, but also provides convenience for subsequent bridge deck maintenance and environmental protection work.

[0008] To solve the above problems and achieve the above-mentioned invention objectives, this utility model provides a non-welded, easily installable and detachable temporary protective device for trestle bridge surfaces, achieved through the following design structure and technical solution:

[0009] As an improvement to the non-welded, easily installable and disassembled temporary protection device for the bridge surface of this utility model, it includes:

[0016] The tightening hole (11) is a bolt hole, and a tightening element (2) is provided inside the bolt hole.

[0017] As a further improvement of the present invention, the clamping member (2) is a common bolt.

[0018] As a further improvement of the present invention, the clamping member (2) is also connected to a limiting pressure plate (21), which is connected to the working end of the clamping member (2).

[0019] As a further improvement of the present invention, the limiting pressure plate (21) is a square or circular plate-shaped component;

[0020] A protective pad is also provided on the limiting pressure plate (21), and the protective pad is set at the contact connection between the limiting pressure plate (21) and the steel bridge (8).

[0021] As a further improvement of the present utility model, the mounting part (3) is a sleeve with an internal thread section. A through hole (31) is provided at the upper end of the sleeve. After the bolt passes through the through hole (31) and the pin hole (42) at the lower end of the protective column (4), the mounting part (3) and the protective column (4) are connected as a whole, and the end is limited and fastened by a locking nut.

[0022] A drainage hole (32) is also provided through the outer wall on one side of the lower end of the sleeve.

[0023] As a further improvement of the present invention, the protective column (4) is a solid rod-shaped body or a hollow tubular component, wherein:

[0024] A spherical or semi-circular protective cap (41) is provided at the top of the hollow tubular component.

[0025] A pin hole (42) is provided at the lower part of the protective column (4).

[0026] As a further improvement of the present invention, the retaining ring (5) is a ring structure, and an anti-detachment limiting member (51) is provided in the middle of the non-connecting end of the retaining ring (5). The anti-detachment limiting member (51) is a C-shaped, U-shaped or V-shaped structure with one end open, used to limit and fix the protective rope (6).

[0027] As a further improvement of the present invention, it also includes a reinforcing plate (7), one end of which is connected to the top of the upper end of the clamping member (1), and the other end is connected to the mounting member (3);

[0028] On the outer surfaces of the clamping component (1), the tightening component (2), the mounting component (3), the protective post (4), the retaining ring (5), and the protective rope (6), from the inside out, there are injection molding layers, anti-rust layers, waterproof layers, and warning layers, with fluorescent powder coated on the warning layers; wherein:

[0029] The protective rope (6) is a steel wire rope.

[0030] The working principle is as follows: Before using the above-mentioned non-welded, easy-to-install and dismantle temporary protective device for trestle bridges, construction personnel only need to prepare a reasonable number of protective devices of this utility model design and transport them to the designated construction location by manual labor or corresponding handling equipment for installation as backup.

[0031] During installation, firstly, the operator will install multiple of these utility models on the ends of the bridge deck on both sides of the steel bridge (8) by clamping the open ends of the clamping parts (1) at equal or unequal distances. After adjusting them to the appropriate positions, the operator will then use the tightening holes (11) to tighten and limit them, so that the clamping parts (1) and the steel bridge (8) are clamped and limited as a whole.

[0032] Then, after ensuring that the clamping part (1) is securely and reliably engaged with the steel bridge (8), the operator inserts the protective column (4) into the mounting part (3) in a plug-in manner. After the bolt passes through the through hole (31) on the mounting part (3) and the pin hole (42) at the lower end of the protective column (4), the mounting part (3) and the protective column (4) are connected as a whole, and the ends are locked and tightened by locking nuts. According to the above installation method, multiple protective devices of this utility model are installed in rows on both sides of the bridge deck end of the steel bridge (8).

[0033] Next, the operator uses the protective rope (6) to pass through the shackles (5) on each of the protective posts (4) arranged in a row at the same horizontal height, so as to fix the protective rope (6) securely and reliably to the protective post (4) and connect them to form a protective fence structure, which serves as a temporary warning and protection function. The operator can then carry out the corresponding subsequent construction work on the bridge deck of the steel bridge (8) to complete the protection work.

[0034] During the entire implementation process described above, the operator needs to periodically inspect each component of this utility model. If one or more components become loose, the operator only needs to tighten each component.

[0035] Finally, as time goes by, once all the construction work is completed, the operators only need to dismantle this utility model.

[0036] During dismantling, firstly, the operator only needs to remove the protective ropes (6) from the shackles (5) on the protective posts (4);

[0037] Then, loosen the locking nut, remove the bolt, and remove the protective post (4) from the mounting part (3);

[0038] Finally, the operator loosens the clamping part (2) set on the top of the clamping part (1), and then removes the clamping part (1) that is locked on the end of the bridge deck of the steel bridge (8). The above operation is repeated in this way to complete the removal of other protective devices until all the removal work of this utility model is completed.

[0039] Meanwhile, after the operators clean and repair the various components of this utility model, they transport them to the designated tool storage warehouse by hand or with appropriate handling equipment for storage, so that they can be reused in the next cycle.

[0040] The beneficial effects of this utility model compared with the prior art are:

[0041] 1. This utility model has a simple structure and a novel and reasonable design. It adopts a non-welded, easily detachable steel trestle bridge temporary protection device. Its components are manufactured in the factory, allowing for quick installation, reducing labor costs, eliminating the need for welding connections, minimizing material damage, and increasing reusability. The use of a detachable protective structure during bridge construction can improve construction safety, increase efficiency, reduce costs, and has high flexibility and adaptability. This protective structure not only meets the safety requirements during construction but also provides convenience for subsequent bridge maintenance and environmental protection work.

[0042] 2. Because the present invention has a limiting pressure plate on the tightening end of the tightening member, it can effectively prevent the tightening member from shifting or loosening during construction due to excessive pressure or other factors. By restricting the free displacement of the tightening member, the friction at the connection with the bridge deck is increased, ensuring its stability during the bridge deck construction process and avoiding the impact on the quality and safety of the entire structure due to the displacement of the tightening member.

[0043] 3. With the limit plate installed, the clamping parts can be held more precisely in the predetermined position, avoiding displacement caused by uneven materials or construction errors. This ensures precision control during construction, which helps to ensure the smooth assembly and stability of the bridge deck structure. It can reduce the need for frequent adjustment of the clamping parts during construction. Construction personnel do not need to frequently check or adjust the position of the clamping parts, thereby improving construction efficiency and reducing unnecessary downtime and operation time. At the same time, it also prevents the risk of loss of the clamping parts and ensures the reliability of construction.

[0044] 4. This utility model, by installing a protective cap on the top of the bridge deck protective column, can effectively prevent damage or wear to the top of the protective column. During the use of the bridge, the top will be exposed to the sun for a long time or be washed by rain. The protective cap can reduce the impact of these factors on the top of the protective column and extend its service life. At the same time, the protective cap can effectively block rainwater, snow water and other liquids from directly entering the interior of the protective column, preventing moisture from entering and causing the interior of the column to become damp. The installation of the protective cap can effectively avoid this situation.

[0045] 5. By installing protective caps, the tops of the protective posts present a cleaner and more aesthetically pleasing appearance, enhancing the overall visual effect of the bridge deck. Especially after the bridge has undergone long-term use, the protective caps not only serve a functional purpose but also improve the bridge's appearance, preventing the exposed post tops from looking rough or unsightly.

[0046] 6. This utility model, by incorporating an anti-slip limiting component on the shackle used for installing the protective rope, prevents the rope from accidentally falling off or slipping, ensuring that the rope remains fixed even in emergencies. The anti-slip limiting component, by ensuring a tight connection between the rope and the shackle, improves the reliability and stability of the entire protective system, reducing the hassle of multiple checks or adjustments required by operators during installation and disassembly. Operators can complete the installation and adjustment of the protective rope more quickly and conveniently.

[0047] 7. Due to the reinforcing plate, this utility model can enhance the stability of the overall structure of the clamping part (1) and the mounting part (3), extend the service life of the device, and save energy and protect the environment;

[0048] 8. The exterior of this utility model is coated with anti-rust paint and a waterproof layer, which can prevent rusting and extend the service life of the entire protective device. It is environmentally friendly and saves resources. At the same time, the exterior of the protective device is coated with a self-luminous fluorescent material, which can clearly mark the location of the protective device at night or in dark indoor and underground construction environments. It can effectively play a safety reminder role, improve visibility, make it easy for people to identify, and increase safety in construction and life. Attached Figure Description

The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0065] In summary, a more specific embodiment of this utility model is as follows:

[0071] Clamping ring 5, there are several clamping rings 5, and several clamping rings 5 ​​are connected to the outer wall of the protective post 4; used to install the protective rope 6.

[0072] Furthermore, the clamping member 1 is a U-shaped or C-shaped plate-like component with one end open, and tightening holes 11 are symmetrically opened on the top of the U-shaped or C-shaped plate-like component.

[0073] Furthermore, the tightening hole 11 is a bolt hole, and a tightening element 2 is provided inside the bolt hole.

[0074] Specifically, the clamping member 2 is a common bolt.

[0075] In this utility model, the clamping member 2 is a hexagonal bolt or a flat-head bolt.

[0076] Furthermore, the mounting component 3 is a sleeve with an internal thread section. A through hole 31 is provided at the upper end of the sleeve. After the bolt passes through the through hole 31 and the pin hole 42 at the lower end of the protective post 4, the mounting component 3 and the protective post 4 are connected as a whole, and the end is limited and fastened by a lock nut.

[0077] A drainage hole 32 is also provided through the outer wall on one side of the lower end of the sleeve.

[0078] In this utility model, the drainage hole 32 enables the water accumulated inside the mounting component 3 to be discharged in time during rainy weather, making the mounting component 3 and the protective column 4 less prone to rust and corrosion, thus extending their service life.

[0079] Before using this embodiment 1, construction personnel only need to prepare a reasonable number of protective devices with the design structure of this utility model, and transport them to the designated construction location by manual labor or corresponding handling equipment for installation as backup.

[0080] During installation, the operator first installs multiple of these utility models at equal or unequal distances on both sides of the bridge deck of the steel bridge 8 through the open end of the clamping part 1. After adjusting them to the appropriate position, the operator then uses the tightening hole 11 to tighten and limit them, so that the clamping part 1 and the steel bridge 8 are clamped and limited as a whole.

[0081] Then, after ensuring that the clamping part 1 is securely and reliably engaged with the steel bridge 8, the operator inserts the protective column 4 into the mounting part 3 in a plug-in manner. After the bolt passes through the through hole 31 on the mounting part 3 and the pin hole 42 at the lower end of the protective column 4, the mounting part 3 and the protective column 4 are connected as a whole, and the ends are limited and tightened by locking nuts. According to the above installation method, multiple protective devices of this utility model are installed in rows on both sides of the bridge deck end of the steel bridge 8.

[0082] Next, the operators use protective ropes 6 to pass through the shackles 5 on each of the protective posts 4 arranged in a row at the same horizontal height, thereby securing the protective ropes 6 to the protective posts 4 to form a protective fence structure, which serves as a temporary warning and protection function. The operators can then carry out the corresponding subsequent construction work on the bridge deck of the steel bridge 8 to complete the protection work.

[0083] During the entire implementation process described above, the operator needs to periodically inspect each component of this utility model. If one or more components become loose, the operator only needs to tighten each component.

[0084] Finally, as time goes by, once all the construction work is completed, the operators only need to dismantle this utility model.

[0085] During dismantling, the operator first only needs to remove the protective ropes 6 from the retaining rings 5 ​​on the protective posts 4;

[0086] Then, loosen the lock nut, remove the bolt, and remove the protective post 4 from the mounting part 3.

[0087] Finally, the operator loosens the clamping member 2 located on top of the clamping member 1, and then removes the clamping member 1 that is engaged with the end of the bridge deck of the steel bridge 8. The above operation is repeated in this way to complete the removal of other protective devices until all the removal work of this utility model is completed.

[0088] Meanwhile, after the operators clean and repair the various components of this utility model, they transport them to the designated tool storage warehouse by hand or with appropriate handling equipment for storage, so that they can be reused in the next cycle.

[0089] Example 2

[0090] This embodiment 2 is the same as embodiment 1, except that a protective pad is provided at the open end of the clamping member 1, and the protective pad is provided at the connection contact part between the clamping member 1 and the steel bridge 8.

[0091] Specifically, the protective pad is a rubber pad, and several integrated rubber protective protrusions are provided on the outside of the rubber pad.

[0092] When this embodiment 2 is used, because a protective pad that matches the clamping part 1 is provided at the connection contact point between the clamping part 1 and the steel bridge 8, it can not only play a protective role and ensure the integrity of the overall structure of the clamping part 1 and the steel bridge 8, but also increase the friction at the connection point, so that the clamping part 1 is engaged on both ends of the bridge deck of the steel bridge 8 and connected to the bridge deck of the steel bridge 8 into an integral structure, thereby making the connection and fixation more stable and reliable, and ensuring construction safety.

[0093] The specific usage is the same as in other embodiments, and will not be repeated here.

[0094] Example 3

[0095] This embodiment 3 is the same as other embodiments, except that the tightening member 2 is also connected to a limiting pressure plate 21, which is connected to the working end of the tightening member 2.

[0096] In this utility model, the limiting pressure plate 21 is used to increase the contact area between itself and the steel bridge 8, making its fixation more stable and reliable.

[0098] A protective pad is also provided on the limiting pressure plate 21, and the protective pad is set at the contact connection between the limiting pressure plate 21 and the steel bridge 8.

[0099] Specifically, the protective pad is a rubber pad, and several integrated rubber protective protrusions are provided on the outside of the rubber pad.

[0100] When this embodiment 3 is used, a protective pad that matches the contact connection between the limiting pressure plate 21 and the steel bridge 8 is provided. This not only provides protection and ensures the integrity of the overall structure of the limiting pressure plate 21 and the steel bridge 8, but also increases the friction at the connection, making the connection more stable and reliable, and ensuring more reliable and safe construction.

During bridge use, the tops are exposed to prolonged sun exposure and rain erosion; the protective caps reduce the impact of these factors on the pillar tops, extending their service life. Simultaneously, the protective caps effectively prevent rainwater, snowmelt, and other liquids from directly entering the pillar's interior, preventing moisture intrusion and internal dampness. Furthermore, the protective caps give the pillar tops a cleaner and more aesthetically pleasing appearance, enhancing the overall visual appeal of the bridge deck. Especially after prolonged use, the protective caps not only serve a functional purpose but also improve the bridge's appearance, preventing exposed pillar tops from appearing rough or unsightly.
