How to reserve the water pipe pressure trough in place at one time? This article summarizes the construction points of three common situations and provides front and back cases of the site for your reference.
(I)
Bathroom reverse sill water supply several words bending groove
(1) Bathroom reverse sill water supply several words bending groove must be made of aluminum alloy or steel mold, and the molding quality is good;
(2) The depth of the pressing groove is 30mm, the inner port width is 30mm, and the outer port width is 50mm. In a 100mm thick wall pressing groove, the inside and outside are staggered by 100mm, and the spacing between the hot and cold water pipe grooves is ≥200mm (when the wall thickness is ≥150mm, the positive pressure grooves are faced with the inside and outside).
Correct way to do:
Error way to do:
(II)
bathroom full cast-in-place wall water supply several-character bending groove
(1) bathroom full cast-in-place wall water supply several-character bending groove adopts aluminum alloy mold, pressing groove height 320mm higher than the structural floor slab, the groove spacing is ≥200mm, and the inner and outer grooves are 100mm apart;
(2) A 400*100mm rectangular square hole is reserved at the wall through the hot and cold water pipes, and a high-strength extruded polystyrene board is used as a mold. After the wall is removed, the polystyrene board should be removed in time and the pipe groove should be repaired.
Correct way:
Error way:
No holes through the wall
(III)
all cast-in-place shearing wall hot and cold water supply pipe pressing tank
(1) The wall pressing tank adopts aluminum alloy molding mold, with good molding quality;
(2) The pressing tank depth is 30mm, the inner port width is 30mm, and the outer port width is 50mm;
(3) The pressure tank spacing of hot and cold water vertical pipe pressing tank: balcony wall-mounted solar water heater 200mm, bathroom bathroom cabinet 280mm, shower shower 150mm, kitchen wash basin 200mm, the pressing tank molding quality is good, and the wall is strictly prohibited from being damaged.
