The abutment piles 2 are arranged in the fill and compaction area 1; the concrete cushion 4 is arranged above the fill and compaction area 1, and the bottom of the concrete cushion 4 is connected to the upper end of the abutment pile 2; the embedded connection device 200 is arranged in the concrete cushion 4 along the left and right directions; the two connection parts 9 are respectively abutted on the left and right sides of the concrete cushion 4; the two locking parts 7 respectively pass through the two connection parts 9 and are connected to the left and right ends of the embedded connection device 200 to lock the connection parts 9 on the concrete cushion 4; the two side formworks 10 are respectively connected to the opposite inner sides of the two connection parts 9, and the two side formworks 10 are respectively supported on the concrete cushion 4, and a casting space for casting the cap beam 3 is enclosed between the two side formworks 10 and the concrete cushion 4. The embedded connection device 200 can be embedded within the concrete cushion layer 4, but is not limited thereto. Specifically, the abutment piles 2 can be located in the center of the compacted fill area 1 to provide support. More specifically, drilling, installing the steel cage, pouring concrete, removing the pile head, installing the pier column reinforcement, and performing the pier column pouring can be performed on a pre-set pile foundation construction platform to form the abutment piles 2. High-quality plain fill is then backfilled to form the compacted fill area 1 around the abutment piles 2.

[0024] See also Figure 3 and Figure 4In one embodiment, the embedded connection device 200 includes a tensioning steel bar 5 and a steel bar connector 6. The two steel bar connectors 6 are respectively mounted on the left and right ends of the tensioning steel bar 5, and two locking members 7 are respectively connected to the two steel bar connectors 6. Furthermore, the locking members 7 are inserted into the steel bar connectors 6 and threadedly connected to them. However, this is not limited to this. For example, the locking members 7 and the steel bar connectors 6 may also be connected by a snap-fit ​​connection.

[0025] See also Figure 3 and Figure 4 In one embodiment, the embedded connection device 200 further includes protective sleeves 11, which are respectively mounted on the two rebar connectors 6. The protective sleeves 11 are used to prevent concrete from entering the inner cavity of the rebar connector 6. By providing the protective sleeves 11 to protect the rebar connector 6 and prevent concrete from entering the inner cavity of the rebar connector 6, the locking member 7 can be effectively removed from the embedded connection device 200, allowing the connector 9, the locking member 7, and the side formwork 10 to be recycled, thereby reducing construction costs.

[0026] See also Figure 3 、 Figure 5 、 Figure 6 and Figure 8 In one embodiment, the connector 9 includes a first connecting portion 93, a second connecting portion 94 formed by bending and extending horizontally from the lower end of the first connecting portion 93, and a third connecting portion 95 formed by bending and extending downward from the distal end of the second connecting portion 94.

By securing the side formwork 10 to the inner side of the connecting member 9 through the connecting nail holes 931, the side formwork 10 can be easily removed after construction is completed.

[0028] See also Figure 2 and Figure 3In one embodiment, the thickness of the concrete cushion layer 4 is 100 mm. The concrete cushion layer 4 serves as an isolation layer between the cap beam 3 and the fill compaction area 1, but the thickness of the concrete cushion layer 4 is not limited thereto.

[0029] In summary, the columnar pier cap beam construction structure 100 of the present invention provides a stable support platform by setting the abutment piles 2, ensuring the stability of the construction platform, and reduces the dependence on the cap beam clamp device by setting the concrete cushion layer 4, the embedded connection device 200, the connector 9, the locking piece 7 and the side formwork 10, thereby reducing the construction cost. At the same time, it simplifies the construction process, reduces the construction time and improves efficiency. The columnar pier cap beam construction structure 100 of the present invention can flexibly cope with the special situation of the oblique intersection of the abutment cap beam and the river bank, and can achieve precise construction and adapt to complex construction site conditions by adjusting the layout of the side formwork 10. The simplification of the construction method reduces the time for equipment installation and commissioning, speeds up the construction progress, and ensures that the project is completed on time with a faster construction speed. In addition, the present invention provides a connector 9, which is clamped on the end of the concrete cushion 4 through a clamping position 91, and the side formwork 10 is provided above one end of the concrete cushion 4 and fixedly connected to the connector 9, thereby positioning the side formwork 10 and limiting the displacement of the side formwork 10. The tensioning steel bars 5 are then fixed to the connector 9 at both ends of the concrete cushion 4 through the locking piece 7, forming a whole, thereby fixing the bottom of the side formwork 10. The tensioning steel bars 5 do not need to pass through the connector 9, but can be connected to the turning connector. The protective cover 11 is used at the connection to protect the steel bar connector 6 to prevent concrete from filling the inner cavity of the steel bar connector 6. The removed connector 9, locking piece 7 and side formwork 10 can be recycled. Therefore, the column-type pier cap beam construction structure 100 of the utility model has the characteristics of simple and convenient installation, effective construction period saving and reduced construction cost.
