The application discloses a movable bridge deck panel installation platform and a construction method thereof. The movable bridge deck panel installation platform comprises a steel plate leg, an angle steel leg and a steel panel, is installed on the upper side of a bridge deck panel, the steel plate leg and the angle steel leg are supported on a main force component of a steel beam, load is transmitted to the main force component of the steel beam, the safety of the steel beam structure is ensured, a caterpillar crane is moved to the steel panel to perform hoisting operation, direct contact with the bridge deck panel is avoided, bridge deck panel cracking is avoided, compared with a traditional automobile crane or a special frame plate machine, the efficiency is higher and the economy is better, through a construction method of cyclically adopting a hoisting bridge deck panel, installing the movable bridge deck panel installation platform, moving the caterpillar crane to the installation platform, hoisting the next bridge deck panel, space occupation of a construction site is less, and the construction method has the advantages of convenient construction, rapidness, convenience, safety and the like.

This invention discloses a bridge pot bearing and control system based on system conversion. A first bearing body and a second bearing body are stacked from top to bottom. The first bearing body has a first mounting plate, and an adjustment component is installed below the first mounting plate. The second bearing body has a second mounting plate, and a test component is installed on the second mounting plate. The test component connects with the adjustment component. While performing pressure testing, the test component, in conjunction with the adjustment component, enables the conversion between three states: fixed pot bearing, unidirectional movable pot bearing, and bidirectional movable pot bearing. This invention monitors the stress on the bearing in real time, calculates the bridge shear force based on the reaction force, and derives the bridge shear force amplification factor under dynamic loads, thus improving bridge design methods and making bridge design safer and more reliable. It can realize the functions of a fixed bearing, a unidirectional movable bearing, or a bidirectional movable bearing, and achieve mutual conversion between bearing types.

This utility model discloses a crane truss structure with a parallel crane beam as the lower chord, comprising: a lower chord structure, which includes two crane beams arranged in parallel and spaced apart, with multiple upper connecting plates connecting the upper flanges of the two crane beams and multiple lower connecting plates connecting the lower flanges of the two crane beams; the two ends of the crane beams are used to connect to corresponding factory building brackets; an upper chord structure, located above the lower chord structure; and a web member assembly, which includes multiple diagonal web members and multiple vertical web members connecting the upper and lower chord structures, with multiple node structures provided on both the upper and lower chord structures; the two ends of the diagonal web members are connected to the corresponding node structures, and the two ends of the vertical web members are connected to the corresponding node structures. This utility model can solve the problems of existing ultra-large span crane beams having large cross-sectional heights, occupying a large amount of space below the rail surface, affecting the air circulation inside the workshop, using a large amount of steel, having complex stress, and being inconvenient to install.

This invention discloses a composite transfer beam structure for easy development of depot superstructures, comprising a superstructure beam, a composite transfer beam, structural columns, at least two superstructure columns, column head reinforcement, and shear reinforcement. Column head reinforcement is pre-installed on the superstructure columns. The ends of the composite transfer beam are connected to adjacent superstructure columns via the column head reinforcement. Shear reinforcement is pre-installed on the ends of the superstructure beam. The composite transfer beam is connected above the superstructure beam via the shear reinforcement and column head reinforcement. The structural columns are connected above the composite transfer beam. This invention not only meets the requirements for subsequent development structures to connect with the superstructure over a relatively long time span, but also possesses strong seismic resistance. It also offers advantages such as convenient construction, high construction quality, low construction cost, low cost of superstructure pre-installation works, and flexible arrangement of the upper columns to meet the needs of later subway superstructure development.

This invention discloses the structure and construction method of an arch bridge viewing platform. The specific structure includes a main beam, with prefabricated platform sections symmetrically arranged on both sides of the main beam along the bridge's centerline. The outer walls of the prefabricated platform sections are connected to cantilevered splicing sections. The ends of the two cantilevered splicing sections furthest from the bridge's centerline coincide with the ends of the main beam. End caps are provided at the ends of the main beam. The inner walls of the prefabricated platform sections are connected to main arch ribs. This invention's arch bridge viewing platform structure solves the problem of poor overall structural integrity in existing arch bridge viewing platforms. The construction method of this invention is simple to operate and allows for rapid construction.

This utility model belongs to the field of construction engineering technology, and specifically relates to a triangular hanging basket device for cantilever construction of cable-stayed bridges. It overcomes the problems of heavy weight and complex operation of existing cable-stayed bridge cantilever casting hanging baskets. It is 1 / 4 lighter than the previous cable-stayed hanging baskets and is simple to operate. It includes a main truss system, an anti-locking wheel travel system, a sliding beam travel system, and a formwork system. The main truss system includes multiple triangular trusses. Each triangular truss includes a longitudinally distributed main beam. Vertically distributed main truss uprights are installed on the main beams. The top of each main beam upright is connected to the front and rear ends of the main beam by two diagonal tie rods. The front and rear ends of the main beams of the multiple triangular trusses are connected as one unit by transversely distributed front and rear upper crossbeams.
