Custom Steel Truss Bridge with Hot-Dipped Galvanized Finish

Site Assembly Short Construction Period Environmental Protection With Steel Structure Bridge

Product Description:

Main structural components: Generally composed of main beams (such as steel box girders, steel truss beams, steel arch ribs, etc.), deck systems (steel bridge panels or composite deck combined with concrete), supports, piers (or abutments) and connecting nodes (bolts, welding, etc.). Among them, the main beam is the core load-bearing member that bears the loads of vehicles, people, etc. and transmits them to the foundation. Advantages of material characteristics: The high tensile and compressive strength of steel enables it to achieve long spans in scenarios such as crossing wide waters and canyons (for example, suspension bridges and cable-stayed bridges often use steel structural main beams); its strong toughness makes it difficult to brittle fracture under loads such as earthquakes and strong winds, making it safer; compared with concrete structures, the deadweight is lighter, which can reduce the difficulty and cost of foundation construction.

Product Use

1.Highway bridges: This is one of the most important uses of steel bridges. Whether it is urban expressways, highways, or main roads connecting urban and rural areas, steel bridges can be competent. Especially when it is necessary to span wide rivers (such as the Yangtze River and Pearl River), lakes, canyons and other terrains, long-span steel bridges (such as cable-stayed bridges and suspension bridges) can achieve unimpeded passage and ensure the continuity of highway traffic. For example, the Runyang Yangtze River Highway Bridge adopts a steel box girder cable-stayed bridge structure, which effectively connects Zhenjiang and Yangzhou and improves regional road transportation efficiency.

2.Highway-rail dual-use bridges: In order to save space and costs, many bridges across rivers and channels are designed to be shared by roads and railways. The high strength and versatility of the steel structure make it an ideal choice. The Wuhan Yangtze River Bridge is a typical dual-use steel truss beam bridge for highways and railways. The upper layer is a highway and the lower layer is a railway, taking into account the needs of both transportation modes.

3.Crossing canyons and deep ditches: In mountainous areas or areas with steep terrain, canyons, deep ditches and other terrains will hinder traffic, and steel bridges can achieve "flying over one bridge" by virtue of their ability to span. For example, Guizhou's Beipanjiang Bridge (partially made of steel structure) spans a 565-meter-deep canyon. It is the world's largest high bridge and solves the problem of traffic congestion in mountainous areas.

4. Crossing existing traffic lines: In cities, if new traffic lines need to span existing railways, highways, subways, etc., steel bridges can be quickly constructed through prefabrication and hoisting to reduce the impact on existing traffic. For example, urban expressways crossing railways often use steel box girders to shorten on-site construction time.

5.Rigid-frame bridge: A structural system between beams and arches. It is a structure that is integrally combined with the upper beam structure under bending and the lower column under pressure. The beams and columns are rigidly connected. The entire system is a bending structure and a structure with thrust. The clearance under the bridge is larger than that of an arch bridge. It is generally used for overpass bridges and overpasses in cities or highways with small spans

Company Introduction

​​Since its founding in 2004, we have always prided ourselves on providing high-quality, customizable and environmentally friendly products-products that are sufficient to meet the diverse needs of customers around the world. "Becoming the trusted and preferred brand supplier of customers" is the goal that our company has always pursued and the criterion that we always encourage ourselves. Adhering to the development philosophy of "providing the most excellent products at the most reasonable prices and the most comprehensive services", we are steadily moving towards the vision of "making steel structures add beauty to the world" without stopping!

The quality control measures of steel structure project are as follows:
1,Strengthen the management of technical personnel
In the construction process of the construction site, the construction personnel occupy the main position in the steel structure operation.In this case, it is necessary to carry out specialized management for the participants of steel structure projects.In the actual management of steel structure project participants, it is found that the actual management work often fails to achieve the expected effect.Firstly, due to the uneven level of professional knowledge and comprehensive quality of the construction personnel involved in steel structure construction, they are not specialized steel structure construction personnel.Secondly, there are many problems in the management of steel structure construction personnel.The employees have loose attitude and poor discipline, which is not easy to be managed in a unified way.Facing this problem, the construction unit should formulate a corresponding management system to restrain them, and should not use conventional management methods.In addition, the pre-service education and training of employees should be strengthened to give full play to the enthusiasm of employees so that they can naturally comply with the rules and regulations.
2, improve the construction control mechanism
In the process of engineering construction, more attention should be paid to the construction of construction quality control mechanism, to ensure the overall quality of engineering construction by perfecting the construction mechanism.First of all, the relevant units should improve the existing construction quality management mechanism, combine the problems that may occur in different construction links, and establish corresponding management and processing mechanisms.Secondly, pay attention to the construction supervision of steel structure.In the process of steel structure construction, many different types of problems may be encountered, and the corresponding processing mechanisms may be different.In order to save the construction time and reduce the construction difficulty, some construction personnel may adopt unreasonable construction methods in the construction process, but these methods cannot meet the construction requirements.Under the supervision of the supervisory unit.All the work can be carried out scientifically and reasonably, the probability of non-standard construction problems is greatly reduced, and the overall quality of the steel structure can be effectively guaranteed.The construction party should establish a sound supervision and management mechanism, encourage the relevant construction personnel to supervise each other, cultivate their sense of crisis and rigorous work attitude, and ensure the rationality of construction.
3,Strengthen construction material management
The quality of materials is directly related to the construction quality and is an important content of construction quality control.In the construction of steel structure project, the cost of steel structure material is very high.Strengthening the construction material management reduces the construction cost while ensuring the subsequent steel structure construction activities are carried out in an orderly manner.This requires comprehensive consideration of construction needs and selection of high quality and inexpensive materials.Specialists conduct in-depth market research, compare and analyze the materials, lay the foundation for more orderly implementation of subsequent steel structure construction activities, and effectively improve the construction quality of steel structure projects.
4,Strengthen the quality control of on-site steel structure components
At the same time, the quality control of on-site steel structure components should be strengthened.First of all, check the samples provided by the permanent representatives and supervisors.If any problem is found, the factory should be notified at one time for correction and to ensure the quality of steel structure components can be transported.On the other hand, the steel structural members need to be inspected by the quality inspector of the supervisory unit upon arrival at the site.
