[0002] Prefabricated concrete structure is a concrete structure formed by assembling and connecting prefabricated concrete components as the main load-bearing components. It is one of the important directions of the development of my country's building structure. It is conducive to the development of my country's industrialization, improving production efficiency and saving energy, and is conducive to improving and ensuring the quality of construction projects. Compared with cast-in-place construction methods, prefabricated concrete structures are conducive to green construction, because prefabricated construction can better meet the requirements of green construction such as land saving, energy saving, material saving, water saving and environmental protection, reduce the negative impact on the environment, and follow the principle of sustainable development.

[0003] When casting precast concrete parts, reserved holes are made by pre-embedded hole-forming molds. After the precast concrete parts are formed, operators are usually required to use tools to pry the hole-forming molds out of the reserved holes. The above method of disassembling the hole-forming molds has the following technical problems: 1. After the precast concrete parts are formed, the hole-forming molds are adhered to the reserved holes and are difficult to remove. It takes a lot of effort to pry them out, which wastes manpower and reduces work efficiency; 2. Using tools to pry the hole-forming molds can easily damage the reserved holes and affect the quality of the holes. In view of this, in-depth research was conducted on the above problems, resulting in this case. Utility Model Content

[0009] The utility model provides a sliding hammer for demoulding embedded parts. It has the following beneficial effects: the sliding hammer for demoulding embedded parts is mainly composed of a force transmission slide rod, on which a mold connection thread section, a front block thread section, a light rod section, a rear block thread section and a handle connection thread section are arranged from left to right, wherein the front block thread section, the light rod section, the rear block thread section and the handle connection thread section are respectively used to connect the front sliding hammer block, the sliding hammer assembly, the rear sliding hammer block and the handle ball. When in use, the operator holds the handle ball in one hand and the sliding hammer assembly in the other hand, and aligns the mold connection thread section at the end of the force transmission slide rod with the embedded mold in the concrete prefabricated part. The hole-forming mold is used, and the handle ball is turned to connect and fix the mold connecting threaded section with the hole-forming mold. The sliding hammer assembly is slid, and the sliding hammer assembly is used to impact the front sliding hammer block and the rear sliding hammer block. Under the action of impact force and vibration, a certain gap is generated between the hole-forming mold and the precast concrete component. The hole-forming mold is not damaged during the demoulding process, and the demoulding can be completed quickly, which reduces the labor of workers and improves the demoulding efficiency. At the same time, there is no direct contact between the sliding hammer and the precast concrete component during the demoulding process, which reduces the probability of damaging the reserved holes of the precast concrete component.
