A mold for making prestressed concrete pipe piles

Abstract

The invention relates to a prestressed concrete pipe pile production mold, which relates to the technical field of prestressed concrete pipe pile preparation, which includes a mounting frame, and the mounting frame is provided with a lower forming die and an upper forming die corresponding to the lower forming die , both ends of the upper forming die and the lower forming die are provided with fixed end plates, and fixing devices are arranged between adjacent upper forming dies and adjacent lower forming dies, and the end plates are connected to the lower forming dies. An installation device is arranged between the forming dies, the upper forming die and the lower forming die are connected through a connection structure, and the inner cavities of the upper forming die and the lower forming die cooperate with each other to form a pile cavity. The present invention has the ability to produce multiple This type of pipe pile can improve the actual production efficiency and reduce the production cycle.

Description

technical field [0001] The invention relates to the technical field of preparation of prestressed concrete pipe piles, in particular to a mold for making prestressed concrete pipe piles. Background technique [0002] Concrete pipe piles play a pivotal role in the existing building construction process. It is mainly used to drive concrete pipe piles into the foundation before the construction of the main body of the building to improve the strength of the foundation and thereby improve the bearing capacity of the foundation; among them In the process of preparing the prestressed pipe pile, it is necessary to use a mold to make the steel cage into the mold, and then inject high-strength concrete into the mold to form the concrete pipe pile by centrifugal means. [0003] The existing Chinese patent with publication (announcement) number CN 206796169U discloses a mold for concave-convex prefabricated piles. The mold for concave-convex prefabricated piles includes an outer mold a...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned existing technical solutions have the following defects: although the above-mentioned concave-convex prefabricated pile mold can be used to make variable-section piles with improved uplift bearing performance through concave-convex molding plates, in the actual use process, the length of the prepared pipe piles needs to be , size, etc. are often different, so it is necessary to prepare pipe piles of different specifications with different types of molds, which will easily cause a large backlog of molds and occupy a lot of factory space; in addition, the weight and length of the molds are relatively large, so changing The mold process is complex and time-consuming, which reduces production efficiency, so there is still room for improvement
