Socket and spigot joint type connecting structure based on T-shaped groove and construction method thereof

Abstract

The present invention discloses a socket and spigot joint type connecting structure based on a T-shaped groove and a construction method thereof. The construction method comprises the steps that a, a bearing platform is cast in place or prefabricated, a notch with the longitudinal section being in a T shape is formed in an upper end opening of the bearing platform, first anti-shear steel bars extending upwards are pre-buried in the bottom wall, corresponding to a large opening, of the bearing platform, first tensile steel bars extending towards the center of the large opening are pre-buried in the side wall, corresponding to the large opening, of the bearing platform, a pier column used for being inserted into the notch is prefabricated, and second tensile steel bars extending towards the outer side of the pier column are pre-buried in the side face of the pier column; b, a grouting material leveling layer is laid on the bottom wall, corresponding to the small opening, of the bearing platform, and the pier column is inserted and erected in the notch; c, the plane coordinates, the elevation and the perpendicularity of the pier column are adjusted; d, the first tensile steel bars and the second tensile steel bars are connected through tensile connecting steel bars; and e, concrete is poured into the notches. The socket type connecting structure based on the T-shaped grooves and the construction method of the socket type connecting structure aim at solving the technical problem that an existing socket type connecting structure is poor in durability and anti-seismic performance.

Description

Technical field [0001] The present invention relates to the field of inserted connection structures, and more particularly to a T-type groove-based connection structure and a construction method thereof. Background technique [0002] For the connection of the underlayer body body and jersey, there is a certain problem with the main connection technology: 1 steel welding or lap and adopt wet-suture joint: Mechanical performance is often similar to the traditional current pouring concrete bridge, but wet The seam will increase the construction time, but also more maintenance time; 2 post-bonded pre-stress connections: the pier body cost is much higher than the traditional current-casting concrete bridge pier, the construction process is complex, and the construction time is longer; 3 grout; 3 grout Metal bellows connection: At present, there are few bridges in foreign countries to use this connection structure for construction. There are few applications in high-earthquake dangerou...
