[0002] With the development and promotion of precast concrete assembly technology, more and more bridge engineering components are being constructed using factory prefabrication and on-site assembly methods instead of on-site casting. Factory prefabrication of bridge structural components can improve construction quality, component manufacturing precision, and thus enhance the durability of the structure.

[0003] However, the construction process for connecting and installing precast cap beams and piers is quite complicated and difficult. The construction period is greatly affected by the site environment and climate, resulting in low construction efficiency. The construction of high piers is also more difficult, making it hard to guarantee the overall construction quality of the project. Utility Model Content

[0006] Furthermore, there are two steel sections, the steel sections are L-shaped, the short plate of the steel section is close to the pier column, and the long side of the steel section is close to the bearing section.

[0007] Furthermore, the top surface of the pier column is evenly provided with screw holes, and bolts are evenly installed on the short side surface of the steel section corresponding to the screw holes, and the bolts are threadedly connected to the pre-embedded holes.

[0008] Furthermore, the receiving section has first through holes evenly distributed on both sides, and the long side of the steel section has second through holes evenly distributed. Tie bolts are installed in the first and second through holes, and the receiving section and the steel section are fixedly connected by the tie bolts.

[0009] Furthermore, the bolt is an M20 high-strength bolt.

[0010] Furthermore, the top surface of the pier column is provided with outward reinforcing bars, and the outer side of the connecting section is filled with post-cast concrete. After filling, the cross-section of the connecting section is the same as that of the standard section.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. The connection process between the pier and the precast cap beam is simple and not easily affected by the site environment and climate, which improves the overall construction efficiency of the project.

[0032] Example:

[0033] like Figures 1-8 As shown, the present invention provides a precast cap beam socket connection structure, including a pier column 1 for installation on the ground;

[0034] Multiple steel sections 2 are symmetrically fixedly installed on the top surface of the pier column 1, and the radial steel sections 2 form a receiving groove 3;

[0035] The precast cap beam 4 is divided into a standard section 401 and a receiving section 402. The receiving section 402 is adapted to the receiving groove 3 and inserted into the receiving groove 3.

[0036] Both sides of the receiving section 402 are fixedly connected to the steel section 2.

[0037] In this way, when connecting the pier 1 and the precast cap beam 4, the precast cap beam 4 is hoisted to directly above the pier 1, and the receiving section 402 is aligned with the receiving groove 3 formed by the radial steel section 2. After aligning with the receiving groove 3, the precast cap beam 4 is lowered. After the precast cap beam 4 is lowered to a certain height, the receiving section 402 is inserted into the receiving groove 3, and the receiving section 402 and the receiving groove 3 are engaged. Finally, the receiving section 402 is fixedly connected to the steel section 2, thus completing the fixed connection between the pier 1 and the precast cap beam 4. The process is simple, not easily affected by the site environment and climate, and improves the overall construction efficiency of the project.

[0038] In this embodiment, there are two steel sections 2. The shape of the steel section 2 is L-shaped. The short plate of the steel section 2 is close to the pier column 1, and the long side of the steel section 2 is close to the receiving section 402. Thus, the receiving groove 3 formed by the radial steel section 2 is a rectangular groove, which facilitates the insertion of the receiving section 402 and the receiving groove 3 and reduces the construction difficulty.

[0039] In this embodiment, the top surface of the pier 1 is evenly provided with screw holes 101, and the short side surface of the steel section 2 is evenly provided with bolts 201 corresponding to the screw holes 101. The bolts 201 are threadedly connected to the pre-embedded holes 101. With this structure, the fixed connection between the pier 1 and the steel section 2 can be completed.

[0040] In this embodiment, the receiving section 402 has first through holes 403 evenly opened on both sides, and the long side of the steel section 2 has second through holes 202 evenly opened. Tie bolts 404 are installed in the first through holes 403 and the second through holes 202. The receiving section 402 and the steel section 2 are fixedly connected by tie bolts 404. With this structure, the fixed connection between the receiving section 402 and the steel section 2 can be completed.

[0041] In this embodiment, bolt 201 is an M20 high-strength bolt, which strengthens the connection between the pier column 1 and the steel section 2 and reduces the possibility of the steel section 2 being misaligned.

[0042] In this embodiment, the top surface of the pier column 1 is provided with an outward reinforcing bar 5, and the outer side of the connecting section 402 is filled with concrete after pouring. After filling, the cross section of the connecting section 402 is the same as the cross section of the standard section 401, thereby ensuring the integrity of the structure and reducing the possibility of defects at the connection between the pier column 1 and the precast cap beam 4.

[0043] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
