Description

Technical Field

[0001] This utility model relates to the field of precast concrete components, specifically to an integrated steel pile cap. Background Technology

[0002] Precast concrete piles are widely used in building construction, and end plates are typically installed at both ends of precast concrete piles. In existing technology, the traditional production of end plates involves many processes. Each end plate requires numerous tension holes and screw holes. First, the cut plates are drilled using a punching and drilling machine, then tapped, and finally planed and trimmed using an edge-cutting machine. Afterward, the end plate and skirt are welded together for the next stage of construction. This method is not only time-consuming, labor-intensive, and material-intensive, but the welding also introduces pollution and potential quality instability. Secondly, existing skirts are also welded together, resulting in a flimsy protective sleeve with weak joints and welds. These easily detach during construction, failing to provide the intended protection after damage and thus failing to adequately protect the ends of the precast concrete piles. Utility Model Content

[0003] The main purpose of this utility model is to provide an integrated steel pile cap to overcome or improve at least one technical problem of the prior art, or to provide a useful alternative.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

The skirt protective sleeve surrounds the outer side of the end plate, and multiple connecting steel bars are welded to the inner side of the end plate. The other end of the connecting steel bars extends into the pile body of the precast concrete pile. The end plate is provided with multiple first through holes, which match the connecting nuts of the main reinforcement bars in the precast concrete pile. The connection between the end plate and the skirt protective sleeve is smoothly transitioned by an arc.

[0006] Furthermore, the end plate has a square structure, the skirt protective sleeve has a rectangular frame structure, the center of the end plate is provided with a second through hole, and sixteen first through holes are distributed on the outside of the second through hole.

[0021] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0022] Combination Figures 1 to 8 This utility model provides an integrated steel pile cap, including an end plate 1 and a skirt protective sleeve 2. The end plate 1 and the skirt protective sleeve 2 are integrally formed structures. The skirt protective sleeve 2 surrounds the outer side of the end plate 1. Multiple connecting steel bars 3 are welded to the inner side of the end plate 1. The other end of the connecting steel bars 3 extends into the pile body of the precast concrete pile. Multiple first through holes 4 are provided on the end plate 1. The first through holes 4 match the connecting nuts of the main reinforcement bars in the precast concrete pile. The connection between the end plate 1 and the skirt protective sleeve 2 is smoothly transitioned by an arc.

[0023] The number of first through holes 4 is positively correlated with the size of the precast pile. The larger the precast pile, the more first through holes 4 there are, and vice versa.

[0024] Example 1

[0025] In this embodiment, the end plate 1 has a square structure, the skirt protective sleeve 2 has a rectangular frame structure, the center of the end plate 1 is provided with a second through hole 5, and sixteen first through holes 4 are distributed on the outside of the second through hole 5. The size of the second through hole 5 matches the size of the center hole of the precast concrete pile.

[0026] Specifically, the first through hole 4 can also be any number of 8, 12, 16, 20, 24, or 28.

[0027] Example 2

[0028] In this embodiment, the end plate 1 is a circular structure, the skirt protective sleeve 2 is a circular ring structure, the center of the end plate 1 is provided with a second through hole 5, and six first through holes 4 are distributed on the outside of the second through hole 5. The size of the second through hole 5 matches the size of the center hole of the precast concrete pile.

[0029] Specifically, the first through hole 4 can also be any number of 6, 7, 8, 10, 11, 12, 13, 14, 15, 16, 17, 20, 24, 26, 30, and 32.

[0030] Example 3

[0031] In this embodiment, the two opposite sides of the end plate 1 and the skirt protective sleeve 2 are both straight structures, and the other two opposite sides are recessed inward. The center of the end plate 1 is provided with a second through hole 5, and ten first through holes 4 are distributed on the outside of the second through hole 5.

[0032] Example 4

[0033] In this embodiment, both the end plate 1 and the skirt protective sleeve 2 are arc structures, with a protrusion at the end of the inner arc and seven first through holes 4 located between the inner arc and the outer arc.

[0034] This utility model features an end plate and skirt protective sleeve that are integrally stamped, forming a one-piece steel pile cap. The one-piece steel pile cap is a single component, stamped into various required shapes within a designed mold, and is not limited to the shapes described in the four embodiments above. In actual manufacturing, molds need to be designed according to the ends of various precast concrete components, precast piles, and irregularly shaped piles. The cut plates are placed in these molds, and mechanical equipment is used to stamp out the integrally formed pile head protective cap.

[0035] When manufacturing precast concrete piles, multiple reinforcing bars need to be welded to the inside of the integrated steel pile cap, extending into the pile body. These bars serve as connecting bars between the integrated steel pile cap and the precast concrete pile, providing better protection for the ends of the precast concrete pile. When multiple sections of precast concrete piles are connected, the integrated steel pile cap, in conjunction with a mechanical connection, reinforces the connection. The joints between the ends of the first and second integrated steel pile cap sections are welded together using electric welding, achieving a double-connection effect.

[0036] Traditional end plate manufacturing involves numerous steps. Each end plate requires many tension holes and screw holes, necessitating the drilling and punching of the cut plates, followed by tapping and edge trimming. This invention eliminates many of these steps, saving energy and materials, and improving the connection performance of multi-section precast concrete piles, achieving a strengthened double-connection effect. This product should be widely used in various fields of precast concrete components and piles.

[0037] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
