Bamboo joint pile mold

Abstract

Disclosed is a bamboo joint pile mold. The bamboo joint pile mold comprises an outer mold body and an inner mold body. The outer mold body comprises a bottom mold plate, side mold plates and a supporting pull rod which is disposed at the top ends of the side mold plates. The exterior of the inner mold body is provided with fixing supporting grooves or connected with supporting nuts. Screw mounting holes are formed in the side mold plates. The inner mold body is fixed to the inside of the outer mold body through screws or supporting rods. The inner mold body includes at least two joints and comprises inner mold body thick sections and inner mold body thin sections, and the inner mold body thick sections and the inner mold body thin sections are arranged in an intersection mode. According to the design of the bamboo joint pile mold, the inner mold body and the outer mold body are combined, and moreover the inner mold body is fixed to the inside of the outer mold body through the supporting rods and the screws so that the function of replacing different inner mold bodies can be achieved and the production demand for bamboo joint piles with different shapes can be met; adjusting plates are mounted between the side mold plates of the outer mold body and L-shaped turnover plates so that the size adjustment of outer mold plates can be achieved, the manufacturing requirement for pipe piles with different sizes and specifications is met, and repeated investment is avoided; and the included angles of the L-shaped turnover plates are larger than 90 degrees, so that the mold and the pipe piles are conveniently taken out, and the work efficiency is improved.

Description

technical field [0001] The invention relates to a bamboo pile mold, which belongs to the technical field of construction. Background technique [0002] With the development of the construction industry, the building height continues to increase, and the requirements for the bearing capacity of the building foundation are also getting higher and higher. The bearing capacity of traditional concrete pipe piles is only affected by side friction resistance and pile end friction resistance. To increase the bearing capacity can only be achieved by increasing the diameter or length of the pipe, which increases the construction cost and difficulty. The prestressed bamboo piles that have appeared in recent years have protrusions on the surface of the body. After entering the soil, through the soil squeezing effect, the protrusions tightly and firmly bite together with the underground soil layer, which greatly increases the friction between the pile body and the soil. , which greatly ...

AI Technical Summary

Problems solved by technology

Its disadvantages: the bottom mold and the cover mold are welded and fixed by the inner steel mold and the outer steel mold, and the size and shape cannot be adjusted. One mold can only produce one specification of pipe piles. For pipe piles that require different shapes and sizes, it is necessary Equipped with multiple sets of molds, resulting in waste of resources

Its disadvantages: the specifications of square piles manufactured by this mold are limited and only square piles can be manufactured
