Rapidly mountable and dismountable four-pin conical die and operation method

Abstract

The invention relates to the technical field of shore protection engineering and particularly relates to a rapidly mountable and dismountable four-pin conical die and an operation method. The rapidly mountable and dismountable four-pin conical die comprises an upper die, a bottom die and sealing plates, wherein the upper die, the bottom die and the sealing plates are correspondingly arranged to form the four-pin conical die; the upper die is fixedly connected with the bottom die through a fixing mechanism; the upper die comprises a side die I, a side die II and a side die III; the side die I and the side die II are fixedly connected with the side die III through fixing mechanisms; the side die I, the side die II, the side die III and the bottom die are same in contour structures; each of the side die I, the side die II, the side die III and the bottom die is provided with three ends; the section of each end is a 120-degreen fan-shaped structure. According to the rapidly mountable and dismountable four-pin conical die, when die plates are assembled and dismounted, a hammer head is only needed and other tools are not needed; the sealing plates are mounted and dismounted by simply striking; fan-shaped lifting rings are designed and cooperate with the die plates in use, so that the four-pin cone can be lifted up, and the demolding operation of the bottom die is completed; the rapidly mountable and dismountable four-pin conical die is simple in structure and convenient to operate.

Description

technical field [0001] The invention relates to the technical field of revetment engineering, in particular to a rapidly assembled and disassembled tetrapod cone mold and an operation method. Background technique [0002] Prefabricated concrete tetrapods are widely used in coastal protection. The prefabricated molds for tetrapods are generally divided into two types. One is the loose formwork. Many formworks are combined with bolts, and the disassembly process is very complicated. , the commonly used mold at present is that the upper limb mold of the four-legged cone and the upper half mold of the three lower limbs form a rigid integral structure. When removing the mold, use a jack to support the concrete top surface of the three lower limbs of the four-legged cone to strongly support the upper mold. This kind of formwork has better integrity, but it wastes a lot of steel, and when pushing the upper formwork, it will become very difficult due to the slight deformation of the...

[0002] Prefabricated concrete tetrapods are widely used in coastal protection. The prefabricated molds for tetrapods are generally divided into two types. One is the loose formwork. Many formworks are combined with bolts, and the disassembly process is very complicated. , the commonly used mold at present is that the upper limb mold of the four-legged cone and the upper half mold of the three lower limbs form a rigid integral structure. When removing the mold, use a jack to support the concrete top surface of the three lower limbs of the four-legged cone to strongly support the upper mold. This kind of formwork has better integrity, but it wastes a lot of steel, and when pushing the upper formwork, it will become very difficult due to the slight deformation of the upper formwork. Sometimes the upper limbs of the tetrapod will be torn, which will affect the prefabrication of the tetrapod. quality
