Title:
BOX FOR PASSING COMPRESSED FLUID THROUGH STONE CONSTRUCTION STRUCTURE
Document Type and Number:
Japanese Patent JPS63241266
Kind Code:
A
Abstract:
Disclosed is an improvement to the passage of pressurized liquids through masonry work using hollow plastic material boxes (17) embedded in pairs in a masonry work (2) and connected together by sheaths (3) also embedded in the masonry work (2) and fixed to the boxes (17). The pressurized liquid plastic material pipes (4), pass through the masonry work (2) through boxes (17) and sheaths (3) in which they are installed by axial sliding motion with diametrical play. The boxes (17) have wheels with a curved profile (11, 13) which hold each pipe (4) in position and bend it while it is guided laterally in a deep grooved curved over a 1/4 of a circle (17i), without friction. With rolling contact of the pipe (4) on the wheels (11, 13), the pipes (4) pass through and are bent from the horizontal position to the vertical position with a minimum axial thrust. Through the free rolling of the wheels (11, 13), it is easy to install them or change them. The boxes are sealed with respect to liquid cement.
