External structure suitable for prefabricated assembled pier stud connection and construction method thereof

Abstract

The invention discloses an external structure suitable for prefabricated assembled pier stud connection and a construction method thereof. The external structure comprises a bearing platform, a pier body and a cover beam which are sequentially arranged from bottom to top; pouring spaces are formed between parts, corresponding to the cover beam and the bearing platform, of the upper end and the lower end of the pier body and are used for pouring concrete, and the cover beam, the pier body and the bearing platform form a fixed whole; the portions, correspondingly connected with the cover beam and the bearing platform, of the upper end and the lower end of the pier body are provided with reinforcing components respectively, and the reinforcing components arranged at the upper end and the lower end of the pier body are both located in the pouring spaces of the corresponding ends of the pier body. The external structure has the technical effects of being stable in structure, reliable in connection, convenient to adjust and capable of being rapidly installed, and can be widely applied to the field of building construction.

Description

technical field [0001] The invention relates to the technical field of building construction. More specifically, the present invention relates to an external structure suitable for the connection of prefabricated assembled pier columns and a construction method thereof. Background technique [0002] At present, the assembly construction of the substructure of highways, municipal bridges and other engineering projects widely adopts the grouting sleeve connection form of pier columns and caps (cover beams), in addition to grouting bellows, socket type, "expanding head" and other types Connection Type. Although the grouting sleeve connection has excellent mechanical properties, the sleeve is expensive, the positioning accuracy is high, the level of the grouting personnel is uneven, and the grouting density detection is difficult, so its application is limited to a certain extent. The grouting bellows also has similar problems. Although the socket-type connection between the p...

AI Technical Summary

Problems solved by technology

Although the grouting sleeve connection has excellent mechanical properties, the sleeve is expensive, the positioning accuracy is high, the level of the grouting personnel is uneven, and the grouting density detection is difficult, so its application is limited to a certain extent. The grouting bellows also has similar problems.

Although the socket-type connection between the pier column and the cap is fast in construction, the amount of cast-in-place connection is large, and it is difficult to control the construction quality; the "expanding head" connection is difficult in both the prefabrication of the shell and the adjustment and sealing of the construction process, and the shape is also poor. unsightly

[0003] With the in-depth implementation of my country's construction industry assembly policy and the increasing demand for rapid construction in various provinces and cities, in view of the current bridge substructure assembly construction connection problems such as unreliable connection, difficult adjustment, slow installation speed, etc.
