Description

Technical Field

[0001] The utility model relates to the technical field of grouting devices, in particular to a PC sleeve grouting experimental device. Background Art

[0002] PC components are short for "prefabricated residential concrete components", also known as prefabricated components. They are finished concrete components made in factories by component processing units. They are assembled, connected and partially cast on site to form concrete structures. They are generally components made by pouring and curing concrete in fixed templates such as steel molds. They have the advantages of high quality, high efficiency, energy saving and environmental protection, and are an important way to achieve residential industrialization. With the advancement of residential industrialization in my country, prefabricated and assembled buildings are emerging. A large number of projects use prefabricated and assembled structures. A large number of grouting sleeves are required in prefabricated shear walls and prefabricated columns. When PC components are prefabricated in factories, it is necessary to ensure that the central axis of the steel bars in the sleeve coincides with the central axis of the sleeve, thereby ensuring the standard connection between the steel bars and the sleeve.

[0003] A grouting sleeve fixing assembly for PC components with a publication number of CN207332121U includes a sleeve body, a grouting cavity is provided inside the sleeve body, a grouting port and a grouting port are provided on the sleeve body, both of which are connected to the grouting cavity, and the assembly also includes a positioning rod arranged in the grouting cavity, the central axis of the positioning rod coincides with the central axis of the sleeve body, one end of the positioning rod is provided with a fixing member that fixes one end of the sleeve body to the fixed template, the other end of the sleeve body is provided with a rubber sealing plug, the other end of the positioning rod is provided with a positioning block, and one end of the steel bar passes through the rubber sealing plug and abuts against the positioning block. The assembly can reliably and accurately fix the grouting sleeve on the fixed template, so that the end face of the grouting sleeve fits tightly with the fixed template, ensuring that the position of the grouting sleeve does not move when producing PC components, and ensuring that there is no leakage of grout during the prefabrication process.

[0004] Although the device can accurately fix the grouting sleeve on the fixed template, it cannot fix sleeves with different outer diameters, which makes the applicability of the device poor. In view of this, we propose a PC sleeve grouting experimental device. Utility Model Content
