Description

Technical Field

[0001] This utility model belongs to the field of steel mold technology for pipe piles, specifically, it relates to a steel mold for pipe piles that is easy to assemble. Background Technology

[0002] Pipe pile steel molds are standardized molds welded and processed from high-strength steel. They are mainly used for pouring concrete and producing prestressed concrete pipe piles with circular cross-sections that meet national standards through prestressing tensioning. Their core function is to ensure that the concrete maintains its designed shape and dimensions during the forming process and withstands the external forces exerted during tensioning, centrifugation, and steam curing. The rollers on the outer ring of the pipe pile steel mold are components that facilitate mounting on centrifugal equipment to drive its rotation. They are usually welded to the outer ring of the pipe pile steel mold, which prevents adjustment of the roller position. Adjustable spacing between adjacent rollers would allow for adaptation to various centrifugal equipment. To improve ease of use, a pipe pile steel mold with convenient assembly is provided. Utility Model Content

[0003] In view of this, the technical problem to be solved by this utility model is to provide a pipe pile steel mold that is easy to assemble, which solves the problem that the position cannot be adjusted in the prior art due to the welding and fixing of rollers.

[0004] To solve the above-mentioned technical problems, this utility model discloses a conveniently assembled steel mold for pipe piles, comprising: an upper mold and a lower mold; the upper mold and the lower mold are fixed together to form a steel mold by screws and nuts; the steel mold is provided with multiple rollers, the rollers are divided into upper rollers and lower rollers, the outer surfaces of the upper mold and the lower mold are provided with reinforcing ribs, the reinforcing ribs have axially distributed arc-shaped reinforcing ribs and circumferentially distributed strip-shaped reinforcing ribs, the inner surfaces of the upper rollers and the lower rollers are provided with limiting plates, the two limiting plates are symmetrically arranged and are locked on both sides of the middle strip-shaped reinforcing rib, the upper rollers and the lower rollers are provided with countersunk threaded holes, the countersunk threaded holes are provided with locking screws, the locking screws are located on the side not of the middle strip-shaped reinforcing rib, the two ends of the upper rollers are provided with slots, the two ends of the lower rollers are provided with insertion parts, the insertion parts and slots are fixed by bolts.

[0005] Furthermore, the outer surfaces of the upper and lower molds are each provided with three circumferentially distributed strip-shaped reinforcing ribs, with the middle reinforcing rib perpendicular to the opening end face of the mold and the reinforcing ribs on both sides being symmetrical.

[0006] Furthermore, the reinforcing ribs on both sides are spaced 45° apart from the reinforcing rib in the middle.

[0007] Furthermore, the aforementioned locking screws are attached to the outer side of the two reinforcing ribs.

[0008] Compared with the prior art, this application can achieve the following technical effects: This invention features a limiting plate on the inner surface of the upper and lower rollers, allowing them to slide on the reinforcing ribs of the upper and lower molds. The locking screws on the upper and lower rollers restrict displacement, and the insertion part cooperates with the slot to lock the upper and lower rollers into a single roller, thus improving the ease of roller displacement.

[0009] Of course, any product implementing this application does not necessarily need to achieve all of the technical effects described above at the same time. Attached Figure Description
