Description

Technical Field

[0001] The invention relates to the technical field of building construction, in particular to a load-bearing steel bridge which is not easily deformed. Background Art

[0002] The surrounding municipal roads of urban building structures are usually completed when they enter the site. In order to facilitate the organization of materials and traffic on site, the gate of the construction site is often opened in the direction of the main road. In order to facilitate the entry of construction vehicles into the construction site, it is necessary to build a driving road in the direction of the gate of the construction site and the main road, which will inevitably interfere with the pedestrian passages on both sides of the road. There are two traditional methods for constructing a driving road. One is to cast a slope between the pedestrian passage and the roadway, and use the slope as a vehicle passage. However, due to the low bearing capacity of the pedestrian passage and the large mass of the construction vehicles, the ground settlement and cracking of the pedestrian passage will occur during the local (wheel) rolling process of the heavy vehicle. Another method is to chisel out the pedestrian passage at the entrance and exit to make the elevation of the roadway consistent and harden it again. However, after the construction is completed, the road needs to be repaved and a new pedestrian passage needs to be constructed. Both methods will cause damage to the pedestrian passage and municipal pipelines, generate additional construction waste, and require construction restoration at a later stage, which will increase the construction cost and extend the construction period. The existing Chinese patent with authorization announcement number CN213896718U discloses a load-bearing steel bridge that is not easy to deform, disperses the load-bearing pressure, and can avoid damage to the pedestrian walkway during construction. Its splicing process is simple, fast, and improves construction efficiency. It has high hardness, can be recycled, is easy to clean, and is suitable for wide promotion and application. However, in the above-mentioned disclosed scheme, the ramp plate is in a suspended state and is prone to deformation under heavy pressure. The greater the deformation of the ramp plate, the greater the impact force of the vehicle on the I-beam and the curbstone, and the easier it is to damage the curbstone. In addition, the ramp and the connecting plate are directly placed on the pedestrian walkway without being fixed. After the vehicle drives up the ramp, there is a horizontal component of force toward the pedestrian walkway, which further increases the impact on the pedestrian walkway. Summary of the invention

[0003] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a non-deformable load-bearing steel bridge which is not easy to deform, has strong impact resistance and is good in practicality.
