Description

Technical Field

[0001] This utility model relates to the field of precast concrete pile production technology, specifically a high-strength concrete pile with reinforcing steel bars. Background Technology

[0002] Concrete piles are piles made of concrete, including ordinary reinforced concrete and prestressed concrete. They have advantages such as saving timber and steel, durability, and low cost, and are widely used in the foundation engineering of hydraulic structures, industrial buildings, civil buildings, and bridges. They are also often used for anti-sliding or water-proofing of slopes and foundation pits. Precast concrete piles, on the other hand, are pre-produced concrete piles that can be used directly in building construction, improving construction efficiency.

[0003] Most existing precast concrete piles are formed by fixing them at the four corners to create a steel reinforcement cage. However, because the inner wall of the concrete pile is relatively smooth, the bond strength between the filling concrete and the inner wall is poor, and the connection points are prone to separation.

[0004] Therefore, in view of this, we studied and improved the existing structure and its shortcomings, and proposed a high-strength concrete pile with reinforced steel bars in order to achieve a more practical value. Utility Model Content

[0005] The purpose of this invention is to provide a high-strength concrete pile with reinforced steel bars to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-strength concrete pile with reinforcing steel bars, comprising a concrete pile base, a skeleton plate, and a positioning plate. The skeleton plate is arranged inside the concrete pile base. Corner slots are provided around the corners of the skeleton plate, and an inner slot is provided through the center of the skeleton plate. Side slots are provided on the inner sides of the four sides of the skeleton plate. Inner protrusions are arranged around the inner sides of the inner slots, and protrusion slots are provided inside the inner protrusions.

[0007] An external reinforcing bar is placed horizontally on the inner side of the corner slot hole, and an internal reinforcing bar is placed horizontally on the inner side of the protruding slot hole. Positioning plates are provided on both sides of the two adjacent sets of skeleton plates. Side clamping plates are provided at both ends of the inner side of the positioning plates, and extension plates are provided on the inner side of the side clamping plates. An interlocking arc groove is opened at the bottom of the extension plates.

[0008] Furthermore, the concrete pile foundation is reinforced by corner slots and four sets of external reinforcing bars.

[0009] The inner convex plate cooperates with each other through the convex plate slot and the four sets of inner reinforcing steel bars.

[0010] Furthermore, the positioning plate and the two sets of adjacent skeleton plates are sized to match each other, and the positioning plate is engaged with the side plate and the side slot.

[0011] Furthermore, the extension plates are arranged symmetrically along the central axis of the positioning plate, and there are two sets of extension plates.

[0012] Furthermore, the extension plate is interlocked with the inner reinforcing steel bars through the interlocking arc grooves, and the positions of the interlocking arc grooves and the inner reinforcing steel bars are mutually coordinated.

[0013] Furthermore, the external reinforcing bars and the internal reinforcing bars are arranged in four sets in a surrounding manner.

[0014] This utility model provides a high-strength concrete pile with reinforcing steel bars, which has the following beneficial effects:

[0015] 1. This utility model improves the strength and production efficiency of precast concrete piles by replacing the traditional skeleton with a skeleton plate. The entire precast soil pile uses double-layer inner and outer reinforcing steel bars as a support. During installation, the outer reinforcing steel bars and the inner reinforcing steel bars are inserted into multiple sets of skeleton plates to form a skeleton structure. Then, the outer template is used to form the entire concrete pile as a whole, thereby ensuring the high strength of the entire concrete pile.

[0016] 2. In this utility model, the inner side of the skeleton plate is provided with a raised inner protrusion. The inner protrusion can increase the contact area with the concrete, so as to improve the adhesion effect, and together with the entire internal reinforcing steel bar, the connection is more compact.

[0017] Positioning plates are installed on both sides of adjacent skeleton plates. The positioning plates use their side clamping plates and the interlocking arc grooves on the inner side of the extension plate to lock the position of adjacent skeleton plates, making the skeleton plates more accurately arranged and the cement piles in each stage area more evenly and evenly distributed, making it less likely to break.

[0024] Please see Figure 1-3 This utility model provides a technical solution: a high-strength concrete pile with reinforced steel bars, including a concrete pile base 1, a skeleton plate 2 and a positioning plate 5. The skeleton plate 2 is arranged inside the concrete pile base 1. Corner slots 201 are opened around the corners of the skeleton plate 2, and an inner slot 202 is opened through the middle of the skeleton plate 2. Side slots 203 are opened on the inner sides of the four sides of the skeleton plate 2.
