The utility model provides a fine solution of interim strutting arrangement of steel case roof beam diaphragm with adjustable fixes inconvenient problem of child on the traditional diaphragm, the interim bearing structure of diaphragm with adjustable comprises pipe, flexible turnbuckle, rotary joint, fixing support etc. and flexible turnbuckle can adjust support member length, and rotary joint can change angle between support member and baffle, bottom plate, and fixing support can increase the stress area between support member and baffle, bottom plate, avoids arousing local deformation. The adjustable steel box girder diaphragm plate supporting device can effectively improve the construction efficiency and ensure the construction quality and safety.

Disclosure of Invention

The utility model aims to provide a device which is easy for positioning a tire on a diaphragm plate of a steel box girder and is beneficial to construction quality and construction safety.

In order to achieve the purpose, the utility model adopts the technical scheme that the temporary supporting device for the transverse clapboard of the steel box girder comprises a telescopic screw thread, a steel pipe, a rotary joint and a support base plate; the two groups of support base plates are provided; two ends of the telescopic screw buckle are respectively connected with two steel pipes, and one end of each steel pipe is welded on a group of support base plates; the middle of each group of support base plates is provided with a rotary joint.

Furthermore, a notch is formed in the connecting portion of the steel pipe and the telescopic screw thread, and the telescopic screw thread is inserted into the notch and welded.

Furthermore, each group of support base plates comprise a first support base plate and a second support base plate, and the end parts of the steel pipes are connected with the first support base plate in a welding mode; the second support base plate is arranged opposite to the first support base plate. A rotary joint is arranged between the first support base plate and the second support base plate.

Further, rotary joint includes support otic placode group, and support otic placode group is including first support otic placode and second support otic placode, and the welding of first support otic placode is at first support bottom plate lateral part, and the welding of second support otic placode is at second support bottom plate lateral part, and through round pin axle and split pin articulated connection between first support otic placode and the second support otic placode.

Compared with the prior art, the temporary supporting device for the diaphragm plates of the steel box girder can be used in combination to form an adjustable temporary supporting device for the diaphragm plates, and the construction quality and the construction safety of the diaphragm plates can be guaranteed by matching a plurality of adjustable temporary supporting devices for the diaphragm plates.
