In order to achieve the purpose, the technical scheme adopted by the invention is as follows: the utility model provides a cup-shaped slot-in type joint construction of prefabricated bridge pier stud and pile foundation one to one, the joint construction is established at its characterized in that pile foundation top, reserves the slot of pier stud in the joint construction, and the hoist and mount of prefabricated pier stud insert in the slot, around the pier stud and fill the concrete in the space between the slot, realize firm connection.
Further, the pile foundation is a reinforced concrete bored pile, and a vertical main steel bar of the bored pile is anchored in the connecting structure.
Furthermore, a cup-shaped slot is arranged at the top of the pile foundation to serve as a connecting structure, and the cup-shaped slot is of a reinforced concrete structure.
Further, the prefabricated pier stud is a reinforced concrete member or a steel structure upright post.
Further, the cross section of the pillar inserted into the slot may be circular, square, rectangular or other polygonal shapes.
Further, the cup-shaped slot type connecting structure is a cylinder with a circular, square, rectangular or other polygonal section. The inner slot is a cavity with a round, square, rectangular or other polygonal cross section, the cross section of the slot is matched with that of the inserted part of the pier stud, and a gap with proper width is reserved between the inner slot and the pier stud.
Furthermore, in order to make the prefabricated pier stud closely attached to the bottom of the slot, cement mortar base mortar with proper thickness is arranged between the prefabricated pier stud and the slot.
Furthermore, the outer wall of the reinforced concrete column in the connection range is roughened or/and a reserved tooth key is reserved, or a shear key is welded on the outer wall of the steel structure column in the connection range.
Further, when one pier comprises a plurality of prefabricated pier columns which are connected with the pile foundations in a one-to-one mode, the connecting structures at the top of the pile foundations can be connected through the tie beams.
Compared with the prior art, the invention has the following advantages and effects: the cup-shaped slot type connecting structure has the advantages of being simple in structure, convenient to construct, reliable in stress and economical in manufacturing cost.
Drawings
Fig. 1 is a schematic sectional elevation view of a prefabricated pier stud and pile foundation cup-shaped slot-in type connection structure and construction sequence.
Fig. 2 is a schematic sectional elevation view of a plurality of prefabricated pier studs and a cup-shaped slot-in type connection structure for pile foundations with additional tie beams.
The figure includes: 1. the cast-in-situ bored concrete pile comprises a cast-in-situ bored pile 2, vertical main reinforcing steel bars 3, a connecting structure 4, slots 5, pier studs 6, joint filling concrete 7, seat grout 8 and tie beams.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
As shown in the figure, the one-to-one prefabricated assembling bridge pier column and pile foundation connecting structure is characterized in that the cup-shaped slot type connecting structure between the top of the pile foundation and the bottom of the prefabricated upright column achieves the purposes of simple structure, reliable connection, convenient construction and low cost.
In detail, referring to fig. 1, a connecting structure 3 is constructed at the top of a cast-in-situ bored pile, a vertical main steel bar 2 of the cast-in-situ bored pile 1 is anchored in the connecting structure 3, and a slot 4 of a pier column is reserved in the connecting structure 3 to form a cup-shaped slot type connecting structure. And paving cement mortar base slurry 7 with proper thickness and a reserved cushion block at the bottom of the slot. After the pier stud 5 is hoisted into the slot 4, the position and the verticality of the upright post are finely adjusted, the upright post is fixed, gap filling concrete 6 is poured into the gap between the periphery of the pier stud and the slot, and firm connection is realized after the bottom base mortar 7 and the gap filling concrete 6 in the slot reach strength.
Furthermore, prefabricated pier stud is steel construction stand, for increase connection anchor effect, can weld shear force keys such as short steel bar, welding nail, short shaped steel at steel construction stand side.
Furthermore, in order to increase the connection anchoring effect, the inner wall of the slot can be roughened or/and a tooth key can be reserved.
Further, when a pier comprises a plurality of columns connected to the pile foundations one-to-one, the connecting structures 3 at the top of the cast-in-situ bored pile may be connected to each other by tie beams 8.
