Problems solved by technology
These two types of steel tie rods are widely used in the installation process of existing small buildings. However, in the process of bridge installation, the installation angle is not constant. This type of steel tie rods cannot well meet the installation needs in special cases. Therefore the present invention aims to develop a brand-new steel tie rod to better meet the needs of bridge installation

A steel tie rod structure applied to bridge installation comprises a base rod and at least one supporting rod, the base rod and the supporting rod are connected through a connecting piece, one end of the connecting piece is fixedly connected with the base rod, the other end corresponding to the connecting piece is provided with limiting blind holes with the number corresponding to that of the supporting rod, and openings of the limiting blind holes face the extending direction of the base rod. The bottom of the limiting blind holes is arranged to be in a spherical inner hole shape, the inner diameter of the spherical inner hole-shaped part on the limiting blind hole is larger than that of other parts of the limiting blind hole, the spherical inner hole-shaped part on the limiting blind hole is further provided with a rotating ball matched with the limiting blind hole in size, the rotating ball is connected with a rotating shaft, and the rotating shaft penetrates through the limiting blind hole to be fixedly connected with an external supporting rod. The steel tie rod structure is unique in structure, convenient and fast to install and maintain, adjustable in installation angle and suitable for more complex bridge installation.
Description
Technical field[0001]The present invention relates to the field of bridge mounting techniques, and more particularly to a steel tie rod structure applied to a bridge mounting.Background technique[0002]Steel pull rods are the necessary components such as the construction of the bridge. The steel pull rod can be pre-tightened. In the prior art, it is authorized to disclose the No. 20,590,7900u to disclose a steel pull rod, including two The rod body is provided in the sleeve of the intermediate end of the two rods and the U-shaped joints provided on the top of the two rods. The U-shaped joint is provided with a pin shaft, and the surface of the steel pull rod is provided or a galvanized layer. The paint coating includes the bottom. Paint layer, middle lacquer layer and topcoat layer, high tensile strength, strong carrying capacity, can achieve large span connection, simple structure, easy to lift installation, publication publication code to cn206346498u patent document disclosed a bu...
