Description

Technical Field

[0001] This invention relates to the field of prefabricated foundation technology, and more particularly to a modular prefabricated foundation. Background Technology

[0002] Traditional transmission tower foundations suffer from long construction periods and high dependence on geological conditions, especially in soft soil foundations or complex terrain, where foundation stability is difficult to guarantee. Existing prefabricated foundations are mostly connected by bolts, which have insufficient pull-out resistance and are easily loosened by external forces. Summary of the Invention

[0003] To address the problem of insufficient pull-out resistance, this invention proposes a modular prefabricated foundation.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A modular prefabricated foundation includes a base with several connectors (N in number) pre-embedded within it. The connectors are arranged in a circular array, and each connector is equipped with a foundation module. These foundation modules form the prefabricated foundation. Each connector includes a web, with a wing plate fixed at both its upper and lower ends. Each wing plate has two connecting grooves with an included angle β (360° / N) between them. Each foundation module includes a base plate module, which is a fan-shaped plate. A mounting seat module is located at the end of the upper surface of the base plate, and its end has a mounting arc groove. The base module also has a T-slot at its end. The central angle of the fan-shaped plate of the base module is α (360° / N). During installation, the web and upper wing plates of the connectors are inserted into the T-slots of the foundation template. The mounting seat modules on the foundation module are arranged in a circular array to form a complete mounting base, and the mounting arc grooves at the ends of the mounting seat modules are arranged in a circular array to form complete mounting holes.

[0005] Furthermore, the upper surface of the base plate module is also provided with an annular protrusion module, the outer diameter of which is equal to the outer diameter of the fan-shaped plate of the base plate module, and a reinforcing rib is fixed between the annular protrusion module and the mounting base module.

[0006] Furthermore, the height of the annular protrusion module is less than the height of the mounting base module.

[0007] Furthermore, the end of the connector is provided with a positioning arc groove, and a positioning groove is provided in the positioning arc groove.

[0008] Furthermore, a positioning plate is fixed at each end of the web plate, and the upper surfaces of the two positioning plates overlap.

[0009] Furthermore, after the N connectors are arranged in a circular array, the positioning arc grooves on them form a complete positioning hole. The positioning hole is provided with a positioning rod of the positioning component. The diameter of the positioning rod is equal to the diameter of the positioning arc groove. The positioning rod is provided with a plurality of positioning plates II. There are N positioning plates II. The positioning plates II are arranged in a circular array on the positioning rod. The positioning plates II are set in the positioning groove of the positioning arc groove.

[0010] Furthermore, the height L1 of the connector is not less than the length L2 of the second positioning plate on the positioning member.

[0011] Furthermore, the height L1 of the connector is equal to the sum of the height L7 of the web and the thickness of the two flanges.

[0012] Furthermore, the width L3 of the upper part of the T-slot is equal to the width L6 of the wing plate of the connector, the height L4 of the upper part of the T-slot is equal to the thickness of the wing plate of the connector, and the height L5 of the lower part of the T-slot is equal to the distance L8 from the lower end face of the upper wing plate to the upper end face of the positioning plate.

[0013] Furthermore, when the connector is embedded in the base, the upper surface of the positioning plate coincides with the upper surface of the base.

[0014] Beneficial effects: In this invention, the web plate and the upper wing plate of the connector are inserted into the T-slot of the foundation template. After the connector is inserted into the T-slot, the first connection hole of the base plate module and the second connection hole on the wing plate of the connector are concentrically set. Then, the first connection hole and the second connection hole are connected together by connecting bolts, thereby restricting the horizontal movement of the connector in the T-slot. Through the cooperation of the wing plate of the connector and the T-slot, the longitudinal movement of the connector is restricted, and the pull-out strength of the foundation is improved.

The central angle of the fan-shaped plate of the base 1 template is α. The angle of α is 360 / N. When N=8, α is equal to 45°. During installation, the web plate 301 of the connector 3 and its upper wing plate 302 are inserted into the T-shaped groove 206 of the base template. The mounting base modules 204 on the base module 2 form a complete mounting base in a circular array. The mounting arc grooves 205 at the end of the mounting base module 204 form a complete mounting hole in a circular array. The base plate module 201 is provided with a first connection hole, which is connected to the T-slot 206. The wing plate 302 of the connector 3 is provided with a second connection hole, which is a threaded hole.

[0019] Reference Figure 9-12 The upper surface of the base plate module 201 is also provided with an annular protrusion module 202.

A reinforcing rib 203 is fixed between the annular protrusion module 202 and the mounting base module 204. The height of the annular protrusion module 202 is less than the height of the mounting base module 204.

[0020] Reference Figure 13-17The end of the connector 3 is provided with a positioning arc groove 304, and a positioning groove 305 is provided in the positioning arc groove 304. A positioning plate 306 is fixed at each end of the web plate 301, and the upper end surfaces of the two positioning plates 306 overlap.

[0021] After N connectors 3 are arranged in a circular array, N=8, the positioning arc grooves 304 on them form a complete positioning hole. The positioning hole is provided with a positioning rod 401 of the positioning component 4. The diameter of the positioning rod 401 is equal to the diameter of the positioning arc groove 304. A plurality of positioning plates 402 are provided on the positioning rod 401. There are N positioning plates 402, N=8. The positioning plates 402 are arranged in a circular array on the positioning rod 401. The positioning plates 402 are set in the positioning grooves 305 of the positioning arc groove 304.

[0022] During the assembly of connector 3, positioning component 4 is positioned at the center. The positioning arc groove 304 at the end of connector 3 is concentrically positioned with the positioning rod 401 of positioning component 4. Positioning plate 402 on positioning rod 401 is inserted into positioning groove 305 and welded to positioning groove 305. The connecting grooves 303 of two adjacent connectors 3 coincide and are fixed together by welding. After all connectors 3 are assembled, the assembled connectors 3 are embedded in the template of base 1, with the upper end face of positioning plate 306 coinciding with the upper end face of base 1.
