Abstract
Description
Technical Field
[0001] The utility model relates to a novel horizontal adjustment device suitable for high-position drop beams, belonging to the technical field of prefabricated box beam erection construction. Background Art
[0002] At present, the width of the expansion joint of a large-span continuous beam is generally around 20cm. After the continuous beam is connected, there is insufficient construction space at the beam joint. In order to ensure the construction progress, high-position beam drop construction is often adopted. During the high-position beam drop construction process, the control of the horizontal position change of the beam body is a very important and extremely dangerous task.
[0003] At present, the construction of high-position beam drop is divided into top beam construction and beam drop. The top beam construction is to set up a high-position beam drop bracket under the beam body, and install a jack on the bracket. It is lifted by the jack, and a pad is installed after each lifting to a certain height, until the beam body falls on the pad after the lifting is completed. The beam drop construction is to remove a pad and use a jack to drop the beam body to a certain height, and repeat the cycle until it falls completely on the pad stone. The entire construction process relies entirely on the deadweight of the beam body. When the beam body undergoes horizontal displacement, the horizontal position of the beam body cannot be adjusted in a timely and effective manner, resulting in the beam body being unable to fall in the designed position, and even overturning accidents due to the shift of the center of gravity. Therefore, it becomes particularly important to limit and adjust the horizontal position of the beam body during the top beam drop construction process. It is urgent to invent a horizontal adjustment device suitable for high-position beam drop construction to ensure the safety and quality of high-position beam drop construction.
