When the reserved hole is located and rechecked, the reserved hole after the structure construction is finished is rechecked in detail according to a deepening drawing, the position of the reserved hole is measured by a total station, and the position deviation of the pre-controlled hole is checked. And measuring the diameter of the reserved hole by using a steel tape.
When the holes are processed, the positions and the sizes of all reserved holes are checked in detail according to a drawing, whether the positions and the sizes of all reserved holes are consistent with the drawing marks or not is judged, if errors exist, the holes are timely communicated with field construction personnel or owners to be solved, chiseling or repairing is timely carried out, the reserved holes and peripheral residues are cleaned, the holes are cleaned completely, the smooth construction is ensured, and no dust falls into all parts of the light guide lighting system when the holes are installed. And sleeving a rainproof plate in advance, putting a test tube down, and checking whether the adjustment of the hole wall is regular or not. And (4) arranging in time to enable the device to be regular, wherein the diameter D = D +50mm of the reserved hole, and D is the diameter of the sleeve.
When the fixed flashing board is subjected to waterproof treatment, the flashing board is firstly sleeved on the reserved hole, a circle of double-sided waterproof adhesive tape is adhered between the flashing board and the reserved hole, the double-sided waterproof adhesive tape is compacted and is tightly adhered to the cement surface of the reserved hole, then the flashing board is uniformly punched, expansion bolts are arranged on the flashing board, and the flashing board is fixed on the reserved hole, and the number of punched holes is 8.
The waterproof layer is externally provided with a heat-insulating layer made of sprayed and foamed polyurethane and having the thickness of 20 mm.
When the lighting tube is installed, firstly, a plurality of groups of light pipes 8 are assembled, then, the straight pipe installation and the bent pipe installation and the horizontal pipe installation of the light pipes 8 are carried out, and finally, the waterproof treatment and the embedding are carried out on the gap.
The light guide pipe 8 is assembled, the first light guide pipe 8 is horizontally placed, the seamed surface of the first light guide pipe is upward, one end with wrinkles of the first light guide pipe is inserted into one end of the second standard pipe, a circle is drawn at the joint by a knife, convenience is provided for tearing off the inner wall protection film later, the joint and the joint of the light guide pipe are sealed by 6 rivets and thin adhesive tapes, then the upper opening of the first light guide pipe is simply sealed by a plastic film, dust is prevented from entering the first light guide pipe, and the inner protection film of the second light guide pipe is torn off. The remaining light pipes are assembled in this way, the two ends of the last light pipe are of standard diameter, and the lower opening of the last light pipe is simply sealed by a plastic film.
The assembled light pipe 8 is slowly inserted into the light guide well from the upper opening of the flashing board, so that the lower end of the light pipe is aligned with the opening of the ceiling and extends out 10mm, and the top of the first light pipe is allowed to be 5mm higher than the upper opening of the flashing board. The method comprises the steps of firstly drawing a marking line and a cross center line on a light guide pipe by adopting a laser plummet instrument, aligning the marking line and the cross center line during installation, then adjusting the elevation of the marking line to accurately position so as to meet the design requirement, selecting more than three points on the surfaces of the center line and the marking line of the light guide pipe as installation positioning measurement points, carrying out computer-aided design and modeling on an installation drawing of the light guide pipe, numbering the specified measurement points, and listing three-dimensional coordinate values of the points on the drawing.
