Description
Technical Field
The utility model relates to the technical field of transportation or assembly of building components, in particular to an anti-tilting system for mounting a high-gravity-center upright post.
Background
In the building construction, the upright column is a very common bearing component and is responsible for transmitting the weight of the upper layer structure to the lower layer structure or even to the foundation, the installation position and the verticality of the upright column are indexes which have important influence on the bearing capacity of the upper layer structure, the verticality of the upright column has particularly serious influence on the bearing capacity of the upright column, and the upright column can ensure that the weight of the upper layer structure is smoothly transmitted to the lower layer structure only when the upright column is strictly vertical.
The column base is a structure for fixing the upright column on the installation foundation and is divided into a rigid connection column base capable of transmitting shearing force (namely, the bottom of the upright column is not disturbed on the installation foundation) and bending moment (namely, the upright column is not inclined) and a hinged column base capable of transmitting shearing force but not transmitting bending moment. The hinged column base cannot transfer bending moment, so that the column can be askew when the column is subjected to larger horizontal force. The rigid connection column base comprises three types of exposed type (the whole column is positioned on the installation foundation, and the lower end of the rigid connection column base is exposed), external wrapping type (the whole column is positioned on the installation foundation, but the lower end of the rigid connection column base is wrapped up) and embedded type (the lower end of the rigid connection column base is embedded in the installation foundation), the capacity of bearing bending moment is sequentially enhanced, and only one type of the hinged connection column base is exposed.
Due to the requirement of beauty or stress, high-gravity-center columns such as inverted cone columns are sometimes used in building construction, and the columns cannot be stably erected by themselves and cannot be inclined due to high gravity center and can only be installed by adopting rigid connection column feet. However, the rigid-connection column base needs to bear bending moment, so that the structure of the rigid-connection column base is more complex, the installation process of the column adopting the rigid-connection column base is longer, the high-gravity-center column such as an inverted-cone column is easy to tilt, temporary fixing is required in the installation process, the cable wind rope is adopted as a common temporary fixing means at present, the effect is not good, the positioning frame is poorer in effect, and the column cannot be basically prevented from tilting.
The applicant found in actual construction that the inverted-cone-shaped column temporarily fixed by using the guy cable is inclined to some extent again after the column base is completely installed even though the column base is adjusted to be in a vertical state, which is fatal to the concrete-covered column base or the embedded column base because the column base cannot be adjusted again. Increasing the number of guy cables by a large amount (by a factor of 4 or more) reduces the inclination, but this significantly increases the construction costs.
The applicant has also found that in the absence of strong winds, the direction of inclination of the inverted cone uprights is random.
