Preferably, the operation platform includes a transverse beam, a longitudinal beam, a secondary beam and a springboard, the transverse beam and the longitudinal beam are connected to form a horizontal frame structure, the secondary beam is connected between the transverse beams, and the springboard is laid on the the upper surface of the platform.

Preferably, railings are provided on both sides of the operating platform.

Preferably, the operating platform is 1.1-1.3m away from the corresponding steel box bridge bottom plate.

Preferably, a ladder is provided between the two hanging columns on one side.

The beneficial effects of the utility model are: the steel box bridge provided by the invention temporarily installs the hanger, the structure is simple, and its structure can be adjusted according to the cross-sectional size of the actual steel box bridge, and the efficiency is improved while reducing labor and construction costs. The safety risk is reduced, and it is worth promoting in more auxiliary measures for the installation of large steel box bridge structures.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described.

As shown in Figures 1 and 2, the steel box bridge temporary installation hanger disclosed by the utility model includes a suspension beam 1 located on both sides of the upper part, a suspension column 2 located on both sides, and an operating platform 3 located below. The hanging beams 1 on both sides are respectively connected with two hanging columns 2 , the operation platform 3 is connected to the lower ends of the hanging columns 2 , and the hanging beams 1 on both sides are connected by connecting members.

As shown in Figure 1, when erecting the temporary installation hanger, the suspension beam 1 is hung on both sides of the steel box bridge 12, and the operating platform 3 is placed under the steel box bridge 12, so that the entire steel box bridge 12 is framed Temporarily install the hanger in the hanger, and connect the hanging beams 1 on both sides through the connecting member to ensure the stability of the overlapping of the hanging beam 1. Two hanging columns 2 are set on each side, and the operation platform 3 is suspended by four The column 2 is hung, which can ensure the stability of the hanging. After the temporary installation hanger is installed, the workman can stand on the operation platform 3 and carry out the construction operation to the steel box bridge 12. The entire temporary installation hanger structure is relatively simple, easy to disassemble, and can be reused, which can reduce construction costs and reduce safety risks of high-altitude operations.

The role of the connecting member is to connect the hanging beams 1 on both sides to stabilize the hanging. It can use ordinary connecting parts, such as round steel, profiles, etc., but in order to ensure that it always maintains sufficient tension, as a preferred method, the connecting member It includes connecting round steel 4 and turnbuckle bolts 5 , the hanging beams 1 on both sides are connected with the connecting round steel 4 , and the connecting round steel 4 on both sides is connected by the turnbuckle bolt 5 . Using the connecting member with this structure, by adjusting the turnbuckle 5, the connecting member can be kept in sufficient tension, and then the hanging crossbeam 1 and the steel box bridge 12 can maintain sufficient contact surface force contact, thereby improving the stability of the hanging .

In order to make the hanger easier to assemble and disassemble, as a preferred method, the hanging beams 1 on both sides are connected to the hanging columns 2 on both sides through high-strength bolts. The use of high-strength bolts can ensure that the connection between the hanging beam 1 and the hanging column 2 has relatively high strength, and at the same time, it is convenient for disassembly and assembly, and can be reused.

There are many specific structural forms of the operating platform 3, which can refer to the erection of each existing construction platform specifically, and as a preferred mode, the operating platform 3 includes a transverse beam 6, a longitudinal beam 7, a secondary beam 8 and a springboard 9, and the transverse The beams 6 and the longitudinal beams 7 are connected to form a horizontal frame structure, the secondary beams 8 are connected between the transverse beams 6 , and the springboard 9 is laid on the upper surface of the operation platform 3 . Among them, the transverse beam 6, the longitudinal beam 7 and the secondary beam 8 form the load-bearing skeleton of the platform, and the springboard 9 is laid on it to facilitate the placement of equipment and the construction work of workers.

In order to improve the safety of the operation platform 3 , as a preferred manner, railings 10 are provided on both sides of the operation platform 3 . The height of the railing 10 is preferably 1m, and the railing 10 is mainly composed of a crossbar and a column, and the railing columns are arranged at a distance of 1m to ensure the safety of people and objects on the platform.

Workers need an appropriate distance to carry out construction operations on the steel box bridge 12 on the operation platform 3 , therefore, as a preferred mode, the distance between the operation platform 3 and the corresponding steel box bridge 12 bottom plate is 1.1-1.3m. And in order to make things easier for workers to pass back and forth between the steel box bridge 12 bridge deck and the operating platform 3, as a preferred mode, a ladder 11 is provided between the two hanging columns 2 on one side. Ladder 11 can be made of round steel, and the spacing between each layer of round steel is preferably 300mm.
