Technical Field

[0001] The utility model relates to the technical field of highway bridges, and particularly relates to an assembled highway steel bridge male end bridge end container unit. Background Technique

[0002] An assembled highway steel bridge is a decomposable, quickly erected standard bridge composed of prefabricated metal components. The steel bridge components are composed of four parts according to their uses, namely the main structure, the bridge deck part, the support connection structure and the bridge end structure. Among them, the main structure includes truss units, end columns, truss bolts, etc., the bridge deck part includes cross beams, edge materials, etc., the support connection structure includes diagonal braces, support frames, wind-resistant tie rods, etc., and the bridge end structure includes bearings, seat plates, and landing plates, etc. There are many types and large quantities of accessories involved. Currently, in situations such as traffic war preparedness and traffic emergencies, it is necessary to transport the selected steel bridge accessories to the construction site. When leaving the warehouse, a large number of operating personnel are required, the labor intensity is high, the operation time is long, the accessories are easily omitted, the safety risk is large, and the components are scattered. It is also difficult to give full play to the efficiency of power tools during on-site installation. Therefore, a highway steel bridge that is conducive to warehouse management, safe loading, road transportation and giving full play to the advantages of modern machinery is needed. Content of the Utility Model

[0003] The purpose of the utility model is to provide an assembled highway steel bridge male end bridge end container unit, which can carry out containerization treatment on steel bridge components in different parts through auxiliary containerization tools to form a container unit with modular, serialized and generalized characteristics. Thus, the problems raised in the above background technique are solved.

[0004] To achieve the above purpose, the utility model provides the following technical solutions:

[0005] An assembled highway steel bridge male end bridge end container unit includes a first truss unit and a second truss unit. The first truss unit and the second truss unit respectively include symmetrically arranged trusses. A support frame is arranged between the tops of the symmetrically arranged trusses. The bottoms of the symmetrically arranged trusses are connected through a fixing frame to prevent the upper support frame from being damaged after the symmetrically arranged trusses swing downward during hoisting. A spatial structure is formed with the trusses through the support frame and the fixing frame to arrange male end bridge end accessories such as wind-resistant tie rods, male end columns, and road edges. A truss male end spacer is arranged on one side between two adjacent trusses of the first truss unit and the second truss unit, and a truss female end spacer is arranged on the other side. The truss male end spacer and the truss female end spacer are respectively connected to the trusses through end column screw units to prevent the first truss unit and the second truss unit from scattering during hoisting and reduce the safety risk.

[0006] Further preferably, support frame bolt groups are arranged at the four corners of the support frame for fixedly connecting the trusses.

[0007] Further preferably, anti-wind tie rods are symmetrically arranged inside the first truss unit. Above the anti-wind tie rods, first bridge seats are symmetrically arranged. Between the symmetrically arranged first bridge seats, a first male end post is further arranged. A anti-wind tie rod sleeper is arranged between the first male end post and the anti-wind tie rods. A curb is arranged above the first male end post.

[0008] Further preferably, the first bridge seats and the anti-wind tie rods, and the anti-wind tie rods and the curb are respectively connected by binders.

[0009] Further preferably, a second male end post is arranged at one end inside the second truss unit, and a second bridge seat is arranged at the other end inside the second truss unit. A curb is arranged above the second male end post. A plurality of diagonal braces are arranged side by side at one end of the second bridge seat.

The other end of the screw penetrates through the truss and the male truss spacer or the female truss spacer. A flat washer and a first nut are arranged at the other end of the screw.

[0012] Further preferably, the female truss spacer is provided with a first through hole at one end of the upper surface, and the male truss spacer is provided with a second through hole in the middle of the upper surface. The sizes of the second through hole and the first through hole match the size of the screw for placing the screw.

[0013] Further preferably, the fixing frame includes a cross bar. A plurality of vertical bars are symmetrically arranged at both ends of the lower surface of the cross bar. A groove is arranged on one side of the vertical bar. A bolt and a second nut are arranged in the groove. The symmetrically arranged lower ends of the trusses are respectively arranged between the symmetrically arranged vertical bars and are fixed by screwing the bolts. Hoisting bolts are symmetrically arranged at both ends of the upper surface of the cross bar. A spring washer is arranged through one end of the hoisting bolt, and a second nut is arranged at the other end of the hoisting bolt.

[0014] Further preferably, the number of male bridge end fittings is four trusses, two support frames, two anti-wind tie rods, two first bridge seats, two first male end posts, two curbs, four diagonal braces, eight sets of support bolts, two second male end posts, two second bridge seats.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] (1) Reduce the proportion of personnel for outbound loading. There are many steel bridge fittings in the prior art with a large quantity. At least 8 people are required for outbound loading. After adopting the containerized structure of the present utility model, only 2 people are needed to complete it.

[0017] (2) Improve the safety factor during transportation. When transporting components in the prior art, the stacking method is adopted, and it is easy to slide off during loading and cause accidents. The utility model processes each component through containerization, which can avoid the occurrence of sliding.

[0018] (3) Improve the loading efficiency. When loading is completed through the component combination method of the prior art, it takes more than 40 minutes for 2 people, but it only takes 5 minutes to complete the loading with the containerized structure.

[0019] (4) Avoid omission of accessories and improve work efficiency. The existing single-piece components have a large quantity and variety, and are prone to omission. After containerization, there is only 1 piece, and there is no risk of omission of accessories.

[0020] (5) Reduce the labor intensity of personnel loading. When loading single pieces, there is repetitive labor for multiple loadings. After containerization, only 1 loading is required, reducing the intensity. Description of the Drawings
