Description

TECHNICAL FIELD

[0001] This practical innovation concerns the field of bridge construction, in particular a flexibly replaceable tension seam between bridge plates with a multi-stage waterproof belt. BACKGROUND OF THE INVENTION

[0002] The bridge stretch joint is a reserved gap in the bridge structure, mainly used to accommodate the natural stretching deformation of the bridge due to temperature changes, material contraction, vehicle load, or soil settlement. The presence of these gaps can effectively release the compression stress of the bridge parts caused by external forces, preventing structural cracks, deformation, or even damage due to extrusion or strain. A water barrier tape is usually installed in the stretch joint. Its key function is to seal the gap and prevent rainwater, melting snow, or other liquids from penetrating the internal structure of the bridge, thus protecting key parts of the bridge, columns, beam bodies, and others.

[0003] Long-term exposure to the external environment, due to extreme temperature cycles such as high temperatures in summer and low temperatures in winter, these factors accelerate material aging, resulting in gradual hardening, fracture or even cracking of rubber or synthetic materials, losing its original elasticity and sealability; secondly, the bridge will be subjected to the dynamic load from vehicle traffic every day, especially heavy vehicles, causing strong shaking and impact, which over time will lead to mechanical wear, resulting in seam failure or local cracking; once the water barrier tape fails, the moisture will penetrate into the bridge along the gap, triggering steel rust, triggering concrete, which may threaten the stability and safety of the bridge; therefore, regular inspections and timely replacement of the aging or damaged water barrier tape,Maintain the bridge's watertightness and extend its service life. Avoid important maintenance measures with high repair costs. SUMMARY OF THE INVENTION

[0004] In view of the above situation, this practical new model provides a flexible replaceable multi-stage waterproof bridge plate stretch seam: with a multi-stage waterproof unit, the waterproof unit can be protected in multiple stages, if a single part is damaged, can still avoid water intrusion into the bridge gap, and has a guide unit to facilitate the replacement of the parts of the waterproof unit, so as to effectively improve the efficiency of maintenance replacement and enhance the user experience;

[0005] This practical new type is a multi-stage waterproof belt that is flexibly replaceable, with a tensile seam between bridge plates, consisting of an F-steel, an F-steel mirror set, an F-steel pair with multiple anchor steel (units) on the outside, an F-steel pair with drain pipes below, an F-steel pair with a multiple water plug unit in the chamber and an F-steel pair with a guide unit, which facilitates maintenance and replacement of the water plug unit.

[0006] The advantages of the above technologies are: (1) This practical new type can provide multiple protection by establishing a multi-stage waterproof unit, in case of damage to the first water holder, the second water holder can replace the first water holder to gain time for maintenance, so as to avoid the water flow directly into the interior of the bridge and damage the bridge in case of damage to the first water holder; (2) This practical new type by setting a guide unit to facilitate the maintenance replacement of the second end belt and the water drainage channel, the guide unit can guide the second end belt and the water drainage channel in the sliding block direction of the F steel under limited visibility, thus facilitating the installation of the second end belt and the water drainage channel for users.
