Description

Technical Field

[0001] The utility model relates to the technical field of building construction, and particularly relates to a highly-sealed wire threading protection sleeve. Background Technique

[0002] During the construction of houses, bridges, etc., some pipeline conduits need to be embedded. There will be gaps or voids left between the pipeline conduits for the convenience of construction or wire threading. After the main project construction is completed, a connecting sleeve is required to connect and process the gaps and voids at both ends of the pipeline conduits and embed them in mortar or concrete. The traditional process is to directly put the sleeve on the port of the pipeline conduit and then carry out the embedding or filling treatment. During the construction process, the insertion part between the sleeve and the pipeline conduit is extremely likely to become loose, resulting in mortar entering the pipeline conduit through the gap between the sleeve and the pipeline conduit during the process of pumping mortar, causing the pipeline conduit to be blocked and affecting the use and maintenance of the later lines. Therefore, in order to solve this problem, the utility model proposes a highly-sealed wire threading protection sleeve. Content of the Utility Model

The connecting coiled plate 1 is curled into a tubular shape, and the tubular shape is used to wrap the wire threading pipe;

[0024] Specifically, the tightening component is arranged outside the connecting coiled plate 1. The tightening component includes a thermoplastic film 101 arranged outside the connecting coiled plate 1. The thermoplastic film 101 is used to shrink and extrude the connecting coiled plate 1 by heating. A filling part for closing the gap at the port of the wire threading pipe is arranged on the inner wall of the connecting coiled plate 1;

[0025] It should be noted that the thermoplastic film 101 and the connecting coiled plate 1 are adhesively fixed. The filling part includes filling strips 3 symmetrically arranged on the inner wall of the connecting coiled plate 1. A filling notch 301 for filling the gap is arranged on the side of the filling strip 3;

[0026] Specifically, the material of the filling strip 3 is styrene-based shape memory polymer, and it is integrally injection-molded with the connecting coiled plate 1. The filling notch 301 is used to fill the gap at the end of the wire threading pipe and block the concrete from entering the wire threading pipe;

[0027] Reinforcing parts for increasing the frictional force between the connecting coiled plate 1 and the surface of the wire threading pipe are arranged on the inner walls at both ends of the connecting coiled plate 1;

[0028] Specifically, the reinforcing parts include friction strips 2 symmetrically arranged on the inner walls at both ends of the connecting coiled plate 1. The shape of the friction strips 2 is rectangular strip-shaped;

[0029] It should be noted that the friction strips 2 are made of silica gel material, and they are adhesively fixed to the connecting coiled plate 1 with glue. Multiple friction strips 2 can increase the frictional force and prevent the connecting coiled plate 1 from sliding outside the wire threading pipe;

The adhesive strip 401 is made of high-temperature resistant glue. The isolation film 402 is used to isolate the adhesive strip 401, which facilitates tearing the adhesive strip 401 after the protective sleeve is used for pasting the adhesive strip 401.

[0033] During actual use, a thermoplastic film 101 is provided on the outer side of the connecting coiled plate 1. The connecting coiled plate 1 is unfolded to wrap the ends of the two conduit pipes. After the connecting coiled plate 1 is tightened due to elasticity, the filling strip 3 enters the gap at the end of the conduit pipe to achieve initial sealing. The adhesive strip 401 in the positioning assembly 4 fixes the crimping intersection of the connecting coiled plate 1. A hot air blower is used to generate hot air to heat the thermoplastic film 101, and the thermoplastic film 101 shrinks and adheres to squeeze and seal the connecting coiled plate 1 again. This design avoids concrete from entering the conduit pipe through the gap caused by the loosening of the sleeve.
