Embodiment Construction

[0028] A connection structure between a prefabricated cap and a prefabricated bridge pier, characterized in that the pier includes a prefabricated pier body 2 and a post-cast belt 3 of a hollow section at the bottom of the pier body, a groove 4 is arranged on the top of the prefabricated cap 1, and a hollow section at the bottom of the pier body The post-cast belt 3 has the vertically protruding steel bars 8 of the prefabricated cap and the vertically protruding steel bars 7 of the prefabricated pier.

[0029] Taking the single-column pier as an example, the structural composition of the present invention is shown in Figure 1 (wherein Figure 1a It is the connection construction elevation of the prefabricated pier and cap, Figure 1b for Figure 1a side view), consists of the following eight parts: 1- prefabricated cap; 2- prefabricated bridge pier; 3- post-casting strip of hollow section at the bottom of prefabricated bridge pier; 4- groove at the top of prefabricated bridge p...

Abstract

The invention discloses a connection construction of a prefabricated bearing platform and a prefabricated pier and a butt joint type construction method for the connection construction. The connection construction comprises the prefabricated reinforced concrete bearing platform, the prefabricated reinforced concrete pier and a reinforced concrete post-cast strip. The connection construction of the prefabricated bearing platform and the prefabricated pier and the butt joint type construction method for the connection construction have the technical characteristics and effects that firstly, through a groove in the top of the prefabricated bearing platform, the shearing behavior of a joint is enhanced effectively, and the stress state of the joint is improved; and secondly, a hollow section post-cast strip construction at the bottom of a prefabricated pier body is convenient to construct, and the durability of the connection construction is improved. With the adoption of the connection construction of the prefabricated bearing platform and the prefabricated pier and the butt joint type construction method for the connection construction, connection of the pier and the bearing platform is reliable in stress, convenient to construct, simple to operate and easy to control, workload of field welding and concrete pouring can be reduced effectively, and the construction progress is quickened.

Description

1. Technical field [0001] The invention relates to the technical field of civil engineering design, in particular to a connection structure of a prefabricated bridge pier and a prefabricated cap and a butt joint construction method thereof. 2. Background technology [0002] At present, the construction of the substructure of urban bridges in my country usually uses the cast-in-place construction method, which not only prolongs the construction period of the bridge, but also brings more adverse effects on the urban environment. With the continuous advancement of my country's large-scale urban construction process at this stage, energy conservation, environmental protection, and low carbon have gradually become the theme of my country's economic development. [0003] One of the main challenges facing the current design of urban bridge structures is that in addition to the safety and durability of the bridge structure, owners and residents also require rapid construction to red...
