The present invention relates to a pipeline sleeve which can connect a pipe by adjusting a height in accordance with the pipeline while being inserted when concrete is poured. A height adjustable sleeve of the present invention includes: an upper tank (10) which comprises a flange (11) at an upper part, and comprises outer wall parts (12, 13) which are extended to a lower part and while being penetrated inside; a lower tank (20) which is formed to be penetrated to accommodate the outer wall parts (12, 13) of the upper tank (10), and comprises a mounting part (21) having a fixing hole (22) able to be fixed to a lower part; and a height adjustment unit (30) comprising a first support part (36) having latching protrusions (33a, 33b) formed at an upper side in the lower tank (20) so that the upper tank (10) can be height-adjusted step by step from the lower tank (20) under the state that the upper tank (10) and the lower tank (20) are inserted to be installed and stepwise multi-stage protrusions (31a, 31b, 31c, 31d) on the outer wall part (12) of the upper tank (10) so as to be supported on the latching protrusions (33a, 33b), and a second support part (37) having protrusions (35a, 35b) formed in the lower tank (20) and L-shaped multi-stage accommodation protrusions (34a, 34b, 34c, 34d) on the outer wall part (13) of the upper tank (10) so as to accommodate and support the protrusions (35a, 35b). Therefore, the present invention provides the effect of being able to adjust height so as to perform height adjustment of the pipeline sleeve simply in accordance with pouring thickness of a concrete building, and has the effect of increasing convenience since a random position can be fixed by a fixing unit like a bolt on the fixing hole during work. |
