Description

Technical Field

[0002] In recent years, as the concept of green energy conservation continues to improve in society, prefabricated buildings have been more widely used in the construction industry. At present, in the prefabricated building structure system, the vertical steel bar connection of the building wall panel is usually connected by sleeve grouting. When constructing the transfer layer, it is necessary to reserve dowel bars in the cast-in-place wall or beam, and complete the transfer layer construction of the prefabricated components through the cast-in-place concrete nodes. However, during the concrete pouring process, horizontal displacement of dowel bars is prone to occur, and the exposed length and position of the reserved dowel bars are very likely to affect the installation quality of the prefabricated prefabricated wall panels; in particular, the corresponding hole position offset on the prefabricated prefabricated wall panels will also cause the prefabricated prefabricated wall panels to be misaligned with the cast wall panels as a whole, which directly leads to the scrapping of prefabricated prefabricated wall panels and increases production costs.

When it is fully positioned, the rotating seat rotates again and drives the inner frame rod to be fully extended. At this time, the inner frame rod is in a fully telescopic state, and the inner ring sleeve is in a polygonal structure under the stretching action, thereby realizing the preliminary positioning of the radial adjustment device.

[0074] As a preferred embodiment, the inner wall cross-section of one end of the sealing ring 33 is set to an arc-shaped structure, so that when the outer clamping plate 36 is in the arc-shaped cross-section of the sealing ring 33, the internal plug can be adjusted by lateral displacement relative to the inner jacket 32. In particular, it is preferred to roughly adjust the length of the internal plug penetrating into the inner jacket, and completely position and fix the internal plug in the inner jacket through the displacement of the shaft plug. At this time, the inner jacket can slide in for a short distance relative displacement, and then the main wall and the assembled wall panel are spliced.
