Embodiment 1

[0034] see Figure 2-8 , the supporting device includes a supporting square column 1 , and a cross base 2 is fixed at the bottom end of the supporting square column 1 . The top of the inner cavity of the supporting square column 1 is rotatably connected with a threaded sleeve 3 through a bearing, and the threaded sleeve 3 is threadedly connected with a lead screw 4 . The bottom end of the screw rod 4 is fixed with a moving block 5 , and the moving block 5 is slidably arranged in the supporting square column 1 . The top of one side of the supporting square column 1 is fixed with a motor 7 through a mounting seat, the output end of the motor 7 is fixed with a first cylindrical gear 8, one side of the first cylindrical gear 8 is meshed with a second cylindrical gear 9, and the second cylindrical gear 9 The inner ring is sleeved on the threaded sleeve 3. The top of the screw rod 4 is fixed with a support base 6, and the motor 7 is used to provide a driving source, so that the sc...

Abstract

The invention discloses a bridge construction supporting method which is characterized by comprising the following steps: S1, pre-adjustment before supporting: a supporting device is moved to a position needing to be supported in advance, then a motor is started, and the motor drives a supporting seat to quickly ascend until the bottom of an inner cavity of the supporting seat is in contact with I-shaped steel at the bottom of a steel frame bridge; s2, fixing between the supporting device and the bridge: starting an air pump, quickly pumping out air in a cavity, keeping a vacuum state, quickly and tightly sucking the bottom of the inner cavity of the supporting seat and I-shaped steel at the bottom of the steel-framed bridge, then moving a reinforcing plate towards the inner side until the reinforcing plate is in contact with the I-shaped steel, and finally rotating a locking bolt to fix the supporting device and the bridge. The I-shaped steel is rotated and moved downwards under the assistance of the nut, so that the sliding seat is limited, and the I-shaped steel is secondarily fixed; s3, protection work is carried out; and S4, protecting the protection mechanism.

Description

technical field [0001] The invention relates to the technical field of bridge engineering, in particular to a bridge construction support method. Background technique [0002] Bridge engineering refers to the work process of bridge survey, design, construction, maintenance and verification, as well as the science and engineering technology to study this process. It is a branch of civil engineering. There are many types of bridges, among which steel frame bridges are also more common. A kind of bridge, when the steel frame bridge is constructed, it is necessary to use the support device to pre-support the bridge body, so that the bridge docking and other work can be carried out normally. [0003] However, most of the traditional bridge construction support methods only have the support function and cannot protect themselves synchronously, so that external vehicles, etc. will directly hit the device, which is easy to break the device, which will directly affect the supporting ...
