Description

Technical Field

[0001] This utility model belongs to the field of prefabricated building technology, specifically relating to an external connection tool for electrical conduits in prefabricated shear walls of prefabricated buildings. Background Technology

[0002] With the rapid development of prefabricated buildings, the installation technology of electromechanical pipelines in prefabricated buildings has been widely applied. In the construction of electrical pipelines in prefabricated buildings, some pipelines and junction boxes are installed in the cast-in-place structure, while others need to be pre-embedded or reserved in precast components. Junction boxes and pipelines in shear walls are embedded during the prefabrication of shear wall components; however, due to different construction times, some pipelines cannot be connected in one go. For example, the exposed parts of conduits in prefabricated shear walls need to be connected to the exposed conduits reserved on the cast-in-place slab surface. The traditional method is to reserve wiring space at the junction of the bottom of the prefabricated shear wall and the cast-in-place floor slab to facilitate the connection of pipelines in the shear wall and exposed joints on the cast-in-place slab surface. However, the traditional construction method has many problems, such as the short pipe length being greater than the net distance between sleeves, insufficient flexibility of the short pipes, poor connection quality, and failure to meet specifications. Poor connections can lead to loosening, and incomplete connections may even cause grout from the subsequent concrete pouring to enter the pipe connection gaps, clogging the pipes. Furthermore, the positions of the pre-embedded pipelines and cast-in-place pipelines in the precast shear wall cannot be perfectly aligned, causing the connection section to be skewed, affecting the connection quality and subsequent wiring efficiency. In actual construction, due to the difficulty of connection, the connecting sleeve is often omitted, and a heated PVC joint is used to soften it before connection. The precision of the joint is very low, the quality is difficult to guarantee, and it clearly does not meet the quality specifications. Utility Model Content

Finally, the joint is manually inspected to ensure the firmness and sealing of the connection, meeting the requirements of the construction specifications.
