[0001] The utility model relates to the field of special-shaped square piles, in particular to a spliced variable-section special-shaped solid square pile. Background Technique

[0002] The pile foundation is a deep foundation that connects the tops of several piles into a whole through a bearing platform to jointly bear static and dynamic loads. A pile is a vertical or inclined foundation member set in the soil. According to different shapes, it can be divided into flat square piles and special-shaped square piles. According to different internal structures, special-shaped square piles can also be divided into two types: solid and hollow.

[0003] However, compared with hollow square piles, solid square piles have greater bearing capacity, but they have too large self-weight, resulting in higher transportation costs and greater hoisting difficulty, and they are more troublesome to install. Content of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides a spliced variable-section special-shaped solid square pile, which solves the problems mentioned in the above background.

[0005] The utility model provides the following technical scheme: a spliced variable-section special-shaped solid square pile, including a solid square pile. One end of the solid square pile is provided with a steel plate slot, and a splicing steel plate is arranged above the steel plate slot. Angle steel slots are opened at the edge positions of the steel plate slot on the edges of the solid square pile. Stirrups are arranged inside the solid square pile at positions passing through the angle steel slots. Reinforcing angle steels are arranged outside the angle steel slots. Side welding perforations are opened inside the reinforcing angle steels corresponding to the positions of the stirrups. Connector bars are installed inside the solid square pile near one end of the angle steel slot. Longitudinal bars are installed inside the solid square pile on the inner side of the stirrups.

[0006] As a further scheme of the utility model: clamping protrusions are installed on the lower surface of the splicing steel plate corresponding to the positions of the steel plate slots, and upper welding perforations are opened inside the splicing steel plate corresponding to the positions of the connector bars.

[0007] As a further scheme of the utility model: the solid square pile includes a convex section and a concave section. An installation joint is installed at one end of the solid square pile away from the steel plate slot, and a plug rod is installed inside the installation joint.

[0008] As a further scheme of the utility model: the reinforcing angle steel is clamped with the angle steel slot, and the outer diameter dimension length of the stirrup is less than the inner diameter dimension length of the side welding perforation.

[0009] As a further scheme of the utility model: the convex section and the concave section are integrally cast, and the plug rod is meshed and fixedly connected with the installation joint.

[0010] As a further solution of the utility model: the splicing steel plate is clamped with the steel plate clamping groove through the clamping protrusion.

[0011] As a further solution of the utility model: the reinforcing angle steel and the stirrup are fixed by welding, and the splicing steel plate and the joint steel bar are fixed by welding.

[0012] As a further solution of the utility model: the stirrup and the longitudinal reinforcement are fixed by welding.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. After the stirrup is bound and welded on the outside of the longitudinal reinforcement, a certain protrusion is left as a whole at one end of the stirrup, and after filling the joint steel bar at the corresponding position, concrete is injected into the inside of the formwork. When the solid square pile is integrally formed, the reserved joint steel bar can be used for splicing of multiple solid square piles.

[0015] 2. After the two splicing steel plates are integrally welded, the reinforcing angle steel is integrally corresponding to the position of the angle steel groove on the outside of the two assembled solid square piles. After the stirrup is clamped into the inside of the side welding perforation, the reinforcing angle steel is integrally welded with the stirrup again, which can ensure the joint strength and flatness of the two butt-jointed solid square piles.

[0022] Next, in combination with the accompanying drawings in the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0023] As Figures 1-5 shown, this embodiment provides a spliced variable cross-section special-shaped solid square pile, including a solid square pile 1. One end of the solid square pile 1 is provided with a steel plate slot 103. Above the steel plate slot 103 is provided a splicing steel plate 6. At the corner position of the steel plate slot 103, an angle steel slot 101 is opened at the edge of the solid square pile 1. At the position where the angle steel slot 101 penetrates through the solid square pile 1, a stirrup 102 is provided. Outside the angle steel slot 101, a reinforcing angle steel 7 is provided. The reinforcing angle steel 7 and the stirrup 102 are fixed by welding. The splicing steel plate 6 and the joint steel bar 104 are fixed by welding. Inside the reinforcing angle steel 7, a side welding perforation 701 is opened corresponding to the position of the stirrup 102. The reinforcing angle steel 7 is clamped with the angle steel slot 101. The outer diameter dimension length of the stirrup 102 is smaller than the inner diameter dimension length of the side welding perforation 701. Inside the solid square pile 1 near one end of the angle steel slot 101, a joint steel bar 104 is installed. Inside the solid square pile 1 on the inner side of the stirrup 102, a longitudinal bar 105 is installed. The stirrup 102 and the longitudinal bar 105 are fixed by welding.

[0024] As Figures 2-3 shown, in this embodiment, a clamping protrusion 602 is installed on the lower surface of the splicing steel plate 6 corresponding to the position of the steel plate slot 103. The splicing steel plate 6 is clamped with the steel plate slot 103 through the clamping protrusion 602. Inside the splicing steel plate 6, an upper welding perforation 601 is opened corresponding to the position of the joint steel bar 104. The solid square pile 1 includes: a protruding section 2 and a recessed section 3. The protruding section 2 and the recessed section 3 are integrally cast. At one end of the solid square pile 1 away from the steel plate slot 103, an installation joint 4 is installed. Inside the installation joint 4, a plug rod 5 is installed. The plug rod 5 is fixedly connected with the installation joint 4 in a meshing manner.

[0025] The working principle of the utility model is as follows: during the casting process, after cutting the overall length of the casting mold, the stirrup 102 is tied and welded outside the longitudinal bar 105. Then, a certain protrusion is left at one end of the stirrup 102 as a whole, and the joint bar 104 is filled at the corresponding position. After injecting concrete into the inside of the formwork, when the solid square pile 1 is integrally formed, a whole special-shaped square pile can be formed by butt-jointing and installing multiple sections of the solid square pile 1, which can reduce the difficulty of hoisting and transportation. When the solid square pile 1 is spliced as a whole, the end of the solid square pile 1 with the steel plate slot 103 is placed face up, and the splicing steel plate 6 is integrally clamped inside the steel plate slot 103 by the clamping protrusion 602. The upper welding perforation 601 inside the splicing steel plate 6 is integrally sleeved outside the joint bar 104. After the joint bar 104 and the splicing steel plate 6 are integrally welded and fixed, the upper solid square pile 1 to be spliced is also welded and fixed by the splicing steel plate 6. After applying an anti-rust coating between the two splicing steel plates 6 and then butting them, the two splicing steel plates 6 are integrally welded. Then, the reinforcing angle steel 7 is placed at the position of the angle steel slot 101 outside the two assembled solid square piles 1 as a whole. After the stirrup 102 is clamped into the side welding perforation 701, the reinforcing angle steel 7 and the stirrup 102 are welded again, which can ensure the joint strength and flatness of the two butt-jointed solid square piles 1.
