Description

Technical Field

[0001] The invention relates to the technical field of building construction, in particular to an assembled road protection steel temporary bridge. Background Art

[0002] In modern society's road construction and emergency rescue and disaster relief scenarios, steel temporary bridges play a vital role.

[0003] With the rapid economic development and the continuous advancement of urbanization, the demand for road construction and maintenance is growing. During road construction, some sections of the road often need to be closed or renovated. In order not to affect the normal passage of traffic, temporary steel bridges need to be built to guide vehicles and pedestrians. In addition, after some natural disasters such as floods and earthquakes, roads may be damaged. In order to restore traffic as soon as possible, steel bridges have become important emergency rescue facilities.

[0004] However, there are many problems with the existing steel temporary bridges in practical applications. On the one hand, the installation process of traditional steel temporary bridges is often complicated and cumbersome. The connection methods used by many steel temporary bridges are not convenient enough and require a lot of time and manpower to install, which may delay the time for traffic restoration in an emergency and affect the rescue work. On the other hand, the firmness of the connection needs to be improved. During use, some steel temporary bridges are prone to loosening and shaking due to loose connections, posing safety hazards to pedestrians and vehicles. Moreover, when vehicles pass frequently, the existing steel temporary bridges have insufficient impact buffering capacity on the road surface, which can easily lead to damage to the steel temporary bridge and the road surface, shortening their service life and increasing the cost of maintenance and replacement.

[0005] To sum up, in order to solve the problems of existing steel temporary bridges such as inconvenient installation, loose connection and insufficient buffering capacity, there is an urgent need for a new type of assembled road protection steel temporary bridge to meet the needs of modern road engineering construction and emergency rescue and disaster relief. Summary of the invention

[0006] The purpose of the present invention is to solve the shortcomings in the prior art and to propose an assembled road protection steel temporary bridge.

[0007] An embodiment of the present invention relates to an assembled road protection steel bridge, which comprises a load-bearing base plate, a load-bearing frame, a frame cover plate, a load-bearing cover plate and a cover plate positioning block.

[0008] In certain embodiments of the present invention, one side of the load-bearing base plate is in contact with the ground, and the other side is threadedly connected to the load-bearing frame. The threaded connection facilitates installation and disassembly, thereby improving construction efficiency. After connection, the threaded connection is torsionally reinforced to enhance the stability and reliability of the connection.

[0009] In certain embodiments of the present invention, the load-bearing frame is connected to the frame cover plate above, also by threaded connection, and torsion reinforcement is performed at the threaded connection to ensure a firm connection between the frame cover plate and the load-bearing frame.

[0010] In certain embodiments of the present invention, a cover plate positioning block is provided between the load-bearing frame and the frame cover plate to ensure the accuracy of the installation position of the frame cover plate.

[0011] In certain embodiments of the present invention, the load-bearing base plate, load-bearing frame, frame cover plate, load-bearing cover plate, and cover plate positioning block are provided with a plurality of screw holes for threaded connection, and the screw holes correspond to each other, so as to facilitate accurate connection of various components.

[0012] In certain embodiments of the present invention, a slope cover is provided at the contact portion of the steel temporary bridge with the road surface, and a buffer block is provided between the slope cover and the road surface. The buffer block is arranged inside the slope cover by a threaded connection, which can effectively reduce the impact on the steel temporary bridge when vehicles pass by, thereby protecting the steel temporary bridge and the road surface.

[0013] Compared with the prior art, the advantages and positive effects of the present invention are:

[0014] 1. Strong connection and high stability

[0015] The present invention adopts a method combining threaded connection and torsion reinforcement, which greatly enhances the connection strength between the various components of the steel temporary bridge. The load-bearing base plate and the load-bearing frame are connected by threads and then reinforced by torsion, which ensures the stability of the bottom structure and can effectively withstand the pressure from above and various external forces. The load-bearing frame and the frame cover plate are also connected by threads and reinforced by torsion, making the entire frame structure more stable and reliable. This double connection method makes the steel temporary bridge less prone to loosening, deformation and other problems during use, and can withstand larger loads. Whether pedestrians, small vehicles or heavy vehicles pass by, the safety and stability of the steel temporary bridge can be guaranteed.

[0016] 2. Easy to install and disassemble, improving construction efficiency

[0017] Each component is provided with corresponding screw holes, which greatly facilitates the installation and disassembly of the steel temporary bridge. In situations where a steel temporary bridge is needed, construction workers can quickly connect the various components with screws, without the need for complex installation processes and a lot of installation time. When it is time to dismantle it after use, the screws can be easily unscrewed and the steel temporary bridge can be disassembled into various components for transportation and storage. This assembled design greatly improves construction efficiency, especially in emergency situations, such as disaster relief, road repair, etc., the steel temporary bridge can be quickly built to restore traffic, providing convenience for rescue work and people's production and life.

[0018] 3. Effectively reduce vehicle impact and extend service life

[0019] The slope cover and buffer block set at the part where the steel bridge contacts the road play an important protective role. The slope cover can protect the edge of the steel bridge and prevent debris and soil on the road from entering the structure of the steel bridge and affecting its normal use. The buffer block is set between the slope cover and the road. When a vehicle passes through the steel bridge, the buffer block can effectively absorb the impact energy brought by the vehicle and reduce the vibration and impact of the vehicle on the steel bridge. This can reduce the degree of wear and damage of the steel bridge during use, extend the service life of the steel bridge, reduce the cost of maintenance and replacement, and also improve the safety of the steel bridge.

Use a wrench or screwdriver to gradually tighten the nuts to ensure a firm connection between the slope cover and the steel bridge. During the tightening process, pay attention to even force to avoid over-tightening one side and loosening the other side.

[0109] Install the buffer block

[0110] Check whether the size and shape of the buffer block meet the requirements and ensure that it is not damaged or deformed.

[0111] Place the buffer block at the designated position inside the slope cover plate, ensuring that the buffer block is in close contact with the slope cover plate.

[0112] According to the design requirements, the buffer block is fixed inside the slope cover plate by threaded connection. It can be fixed by screws and nuts or other suitable connectors. During the installation process, it is necessary to ensure that the buffer block is installed firmly and reliably and will not loosen or fall off during use.
