Title:
PREFABRICATED BEAM COLUMN SLEEVED WITH CORRUGATED PIPE
Document Type and Number:
WIPO Patent Application WO/2022/021105
Kind Code:
A1
Abstract:
Disclosed is a prefabricated beam column sleeved with a corrugated pipe, the prefabricated beam column comprising a prefabricated concrete column (1) and a prefabricated concrete beam (4). The prefabricated beam column is characterized in that an inner groove A (3) is provided in the right side of the prefabricated concrete column (1), a positioning strip A (15) is fixedly connected to an inner side wall of the inner groove A (3), an inner groove B (6) is provided in the left side of the prefabricated concrete beam (4), a positioning strip B (16) is fixedly connected to an inner side wall of the inner groove B (6), a corrugated pipe (13) is clamped inside the inner groove A (3) and the inner groove B (6), the upper end and the lower end of the corrugated pipe (13) are fixedly connected to positioning seats (14), the positioning strip A (15) and the positioning strip B (16) are inserted into holes of the positioning seats (14), the right side of the prefabricated concrete beam (4) is connected to a push rod (7), the right side of the push rod (7) is fixedly connected to a lead screw (9), and the lead screw (9) is in threaded connection with a lead screw sleeve (8), such that forward positioning between an in-column embedded pipe (2) and the corrugated pipe (13) and forward positioning between an in-beam embedded pipe (5) and the corrugated pipe are completed; and a handle (10) is rotated to drive the lead screw (9) to perform threaded feeding movement along an inner wall of the lead screw sleeve (8), the lead screw (9) drives the push rod (7) to move forwards, and the push rod (7) pushes the in-beam embedded pipe (5) to perform transverse displacement in a hole groove, such that the orientations of the embedded pipes in the prefabricated beam column are adjusted, and the prefabricated beam column is suitable for being widely popularized and used.
