[0028] The present invention will be described in detail below with reference to specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but are not intended to limit the present invention in any form. It should be noted that, for those skilled in the art, several changes and improvements can be made without departing from the scope of the present invention. These all fall within the scope of protection of the present invention. Example

[0029] This embodiment provides a truss type pile leg resting seat, such as Figure 1-6As shown, it is mainly composed of a base plate 1, a vertical plate 2 and a web 3. The lower surface of the base plate 1 is used to fit and connect with the surface of the foundation, and the vertical plate 2 and the web 3 are fixedly connected to the upper surface of the base plate 1. In some embodiments, a plurality of connecting holes 11 are provided along the circumference of the base plate 1, and the connecting holes 11 are used to allow connecting bolts to pass through and connect to the foundation, thereby achieving a stable connection between the base plate 1 and the foundation, that is, achieving a tie between the shelf and the foundation. The vertical plate 2 includes a first vertical plate 21 and a second vertical plate 22, and the first vertical plate 21 and the second vertical plate 22 are fixedly connected to the upper surface of the base plate 1 in a manner that they are spaced a predetermined distance apart and are parallel to each other. The first vertical plate 21, the second vertical plate 22 and the base plate 1 are all fixedly connected by welding.

[0030] The lower end surface of the web 3 is seated and connected to the upper surface of the base plate 1. Opposite side surfaces of the web 3 are connected to the first and second upright plates 21, 22, respectively. The first and second upright plates 21, 21, 22 are connected to form an I-shaped structure. The web 3 is welded to the base plate 1, first and second upright plates 21, 22, respectively. Some embodiments further include a reinforcement plate 7, which is welded to the outer sides of the first and second upright plates 21, 22, facing the front side surfaces of the web 3. This enhances the overall structural strength and torsional resistance of the upright plate 2.

[0031] The upper end surface 31 of the web 3 is a zigzag structure. The height of the first vertical plate 21 is greater than that of the second vertical plate 22. The web 3 forms a step-like structure from the end connected to the second vertical plate 22 to the end connected to the first vertical plate 21. This structure significantly improves the ease of entry into the truss leg and the stability of the leg placement. The zigzag structure of the upper end surface 31 can be a single-stage zigzag or a multi-stage zigzag. A single-stage zigzag means that the upper end surface 31 has only one bend, while a multi-stage zigzag means that it has multiple bends. A multi-stage zigzag structure provides multiple support points for the truss leg.

[0032] The working principle of the truss leg support provided in this embodiment is as follows: an open, I-shaped support is formed by welding a base plate 1, a first vertical plate 21, a second vertical plate 22, and a web plate 3. The support is then arranged and fixed to the foundation. The main side tube 6 of the truss leg is placed at the bend of the upper end surface 31. At this time, the semicircular tube 61 of the main side tube 6 maintains two contact surfaces with the profile of the bend of the upper end surface 31. The two contact surfaces are two angled surfaces at one bend, ensuring the stability of the truss leg support. Compared to the box-type structure surrounded by two vertical plates, two web plates, and a base plate in the prior art, the truss leg support provided in this embodiment changes the box-type structure to an open, I-shaped structure formed by a single web plate. This allows the truss leg support to be fully welded, solving the problem of the box-type structure being unable to be fully welded internally. While meeting the strength requirements of the box-type structure, it also saves materials and improves manufacturing efficiency. In addition, by using a broken line structure to support the main side tube, the contact surface can always maintain close contact. Compared with supporting the main side tube with an arc surface, the difficulty of manufacturing the web profile is greatly reduced, and the manufacturing efficiency is improved. Example

[0033] This embodiment 2 is formed on the basis of embodiment 1, and improves the placement accuracy of the truss-type pile legs by providing an adjustment pad. At the same time, the adjustment pad and the pressure plate are coordinated to achieve a locking effect on the pile legs, thereby improving the stability of the pile legs. Specifically:

[0034] As shown in Figures 1-6, the upper end surface 31 of the web 3 has a multi-step zigzag profile, and the semicircular tube 61 of the main side tube 6 is not placed at the lowest bend. After the main side tube 6 is placed at a bend in the upper end surface 31, an adjustment pad 4 is installed at the bend below the main side tube 6. The upper surface of the adjustment pad 4 abuts the lower portion of the rack 62 of the main side tube 6. The adjustment pad 4 adjusts the horizontal and vertical position of the main side tube 6 to a predetermined point, thereby improving the placement accuracy of the pile leg. Once the position of the main side tube 6 is adjusted using the adjustment pad 4, the adjustment pad 4 is firmly connected to the web 3 by welding.

[0035] Furthermore, a clamping plate 5 is included. After the adjustment pad 4 is fixedly connected to the web 3, the lower surface of the clamping plate 5 is pressed against the upper portion of the rack 62, and then the clamping plate 5 and the web 3 are fixedly connected by welding. The clamping plate 5 and the adjustment pad 4 cooperate to clamp the rack 62 between them, that is, the main side tube 6 is clamped and locked, thereby improving the stability of the pile leg. Example

[0036] This embodiment 3 is a truss type pile leg placement platform formed on the basis of embodiment 1 or embodiment 2. Figure 1-6 As shown, it is formed by the truss-type pile leg placement seat described in Example 1 or Example 2, and also includes connecting bolts 8.

[0037] like Figure 6 As shown, there are multiple truss-type pile leg resting seats, and the multiple truss-type pile leg resting seats are arranged in an array on the foundation 9. A plurality of connecting holes 11 are evenly distributed along the circumference of the base plate 1, and the connecting bolts 8 are connected to the foundation 9 through the connecting holes 11, thereby achieving a stable connection between the resting seat and the foundation 9, ensuring the stability of the pile legs after they are placed on the resting seat. In some embodiments, the foundation 9 is cast with multiple layers of materials, which are, from top to bottom, a concrete base layer 91, a plain concrete cushion layer 92, a fly ash three-slag base layer 93, and a gravel cushion layer 94. In some specific embodiments, the thickness of the concrete base layer 91 is 200 mm, the thickness of the plain concrete cushion layer 92 is 100 mm, the thickness of the fly ash three-slag base layer 93 is 350 mm, and the thickness of the gravel cushion layer 94 is 150 mm. The height of the connecting bolts 8 implanted in the foundation 9 should preferably reach the bottom of the plain concrete cushion layer 92 to ensure the connection strength. The truss-type pile leg placing platform provided in this embodiment realizes the connection between the placing seat and the foundation by embedding connecting bolts into the foundation, thereby solving the problem that the placing seat is difficult to use on the foundation without embedded iron, and expanding the applicable scenarios of the placing seat.

[0038] In some embodiments, a hole is drilled at a corresponding location in foundation 9, with the diameter of the drilled hole being larger than the outer diameter of connecting bolt 8. After one end of connecting bolt 8 passes through connecting hole 11 and enters the bottom of the drilled hole in foundation 9, epoxy resin is poured into the hole, forming an epoxy resin bonding layer 10 between connecting bolt 8 and the inner circumference of the drilled hole in foundation 9. Epoxy resin bonding layer 10 effectively strengthens the structural strength of the connection between connecting bolt 8 and foundation 9, further enhancing the stability of the shelf. In some specific embodiments, connecting bolt 8 is M32 hot-rolled ribbed rebar with a length of 340 mm, an inner diameter of 30.5 mm, and an outer diameter of 34.5 mm. The diameter of the drilled hole in foundation 9 is 36 mm. After connecting bolt 8 is driven into plain concrete cushion layer 92, epoxy resin is poured to form epoxy resin bonding layer 10.
