Description

A steel box girder assembly frame structure

Technical field

The invention relates to the technical field of steel box girder, and in particular to a steel box girder assembly frame structure.

Background technique

The tire frame is a kind of mold, which refers to the scaffolding that mainly plays a load-bearing and force-bearing role. It is a special process equipment to facilitate the assembly and welding of mechanical equipment. It is widely used in formwork engineering, steel structure installation engineering, and bridge engineering. Different from commonly used single and double row scaffolding, due to the large difference in the structural form and weight of the support, the design of the tire frame is also very different. Different equipment has different processes, and the form of the tire frame is also different, especially in the construction process of bridges. The assembly of steel box girders requires the production of tire frames for effective support. According to the requirements for plate unit division and large segment manufacturing, a prefabricated steel box girder assembly tire frame is designed to meet the assembly requirements of 5 standard segments and the removal of the entire segment. Transshipment needs.

During the production of the tire frame, due to the requirements of bridge design, the bottom plate of the steel box girder is set in an arc shape. This requires that during the manufacturing process of the tire frame, an arc-shaped support beam needs to be processed as the top support beam to support the steel box girder. Box girders, but due to the different sizes of bridges and the large size of bridges, when processing arc-shaped support beams, it is necessary to bend the huge steel beam while ensuring that the curvature of the bent support beam is accurate. It consumes a huge amount of manpower and material resources. At the same time, once the processing accuracy cannot meet the requirements, it will cause the whole body to be scrapped, which will make the enterprise's production cost high and the processing difficulty high. Moreover, due to changes in the environment or various operations during construction, the longitudinal direction of the tire frame will be affected. Horizontal or longitudinal displacements easily occur between the beams, and these displacements cannot be adjusted. In severe cases, they may even cause damage to the entire frame. This will not only damage the steel box beams, but may even cause major production accidents.

It should be noted that the support of the reinforcing beam 601 effectively improves the stability of the connection between the supporting beam 3 and the adjusting seat 4. When the supporting beam 3 or the adjusting seat 4 is under pressure, the reinforcing beam 601 drives the push rod 603 Move, the push rod 603 moves in the spherical groove 605 through the spherical block 606, and forces the cylinder 602. Therefore, under the resilience of the cylinder 602, the reinforcing beam 601 effectively supports the support beam 3 or the adjustment seat 4. At the same time, It can provide lateral buffering force and ensure the safe connection between the support beam 3 and the adjustment seat 4;

Further, when the longitudinal beam 1 is impacted, the base 701 is driven to move, and the base 701 slides on the four sliding rods 704 through the four sliding holes 703, and drives the four buffer springs 705 to receive force. Under the rebound force, the settings of multiple buffer airbags 706 are combined to offset the impact caused by the longitudinal beam 1, thereby ensuring the safe use of the longitudinal beam 1, and by centrally controlling the buffer airbags 706, when a certain longitudinal beam 1 is vertically When displacement occurs in the straight direction, the adjustment of the longitudinal beam can be easily completed by inflating the buffer airbag 706, ensuring that the entire tire frame supports the steel box beam;

Furthermore, when installing the longitudinal beam 1 on the base 701, insert the longitudinal beam 1 on the connecting rod 801, so that the spreading rod 804 is stretched, and the spreading rod 804 is stuck on the bottom side of the longitudinal beam 1, After the initial fixation of the longitudinal beam 1 is completed, the insertion rod 810 is inserted into the insertion hole 809, and the longitudinal beam 1 can be easily installed on the base 701.

The above are only preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person familiar with the technical field can, within the technical scope disclosed in the present invention, implement the technical solutions of the present invention. Equivalent substitutions or changes of the inventive concept thereof shall be included in the protection scope of the present invention.
