Construction technology of wood structure roof tile disclose .
"Contents of disclosure: I. Material requirements 1. The minimum diameter of round logs of various lengths and specifications (including 4m, 4.5m, 5m, 6m, etc.) shall not be less than 8cm. The sawing plane must be straight without bending. The round logs must be straight as a whole, free from cracking and decay. 2. The waterside strip shall be 2cm * 8cm wood strip, the tile hanging strip shall be 2cm * 3cm wood strip, and the tiger window frame strip shall be 4cm * 8cm wood strip. It is required that the waterside strip, tile hanging strip, and tiger window frame strip shall be square on all sides, without arc, bending, deformation, and decay. 3. The cornice hanging strip shall be 2cm * 13cm wooden strip, painted on one side. The cornice hanging strip shall be straight and square, without arc, bending, deformation and decay. The materials used for the cornice board and the dormer hull must be cut neatly according to the size to avoid waste. 4. Waterproof coiled material used at the lap joint of roof ditch tile must be laid in two layers, and no damaged holes are allowed. 5. The roof glazed tile shall be free of defects such as missing edge, missing corner, dark mark, crack, etc. 2、 Construction process 1. Construction process, The wiring in each compartment shall not be less than three. The circular saw plane shall be adjusted on one plane, and the overall flatness error shall be within ± 1cm. The ridge round wood must be adjusted horizontally or slightly downward toward the cornice (the slope shall not be greater than 5 ‰). The spacing of round timber erection is 60cm. 3. The brick joints must be filled with mortar when fixing round wood bricks, and the bricks used to pad round wood must be filled and reinforced with mortar. No holes shall be left between the wall and the log. 4. Each downstream strip node needs to be firmly connected. The downstream strip is perpendicular to the cornice. The spacing of downstream strip nails is 40cm. When the downstream strip is staggered and lapped, the dislocation direction must be consistent. 5. Use row nails or round nails to fix the tiles on the water strip, and the spacing is based on the tile overlapping distance. The joint shall be nailed firmly on the downstream strip without missing nails. The joints shall be staggered, and there shall not be more than three joints on the same downstream strip. 6. When nailing cornice strips, setting out must be made to ensure that the upper and lower sides of cornice strips are parallel and in a straight line, and no unevenness or bending is allowed. 7. The roof tile is firmly connected with the tile strip by screws, and the tiles are arranged from the cornice layer by layer upward. From left to right and from bottom to top, the upper and lower lapping between tiles shall be subject to the self-locking oblique triangle covering the tiles, and the left and right lapping shall be subject to the smoothness after the tiles are buckled, and the tile seams shall be aligned. When ridges and gutters are encountered during laying, the corners shall be cut with a grinding wheel saw to meet the requirements. 8. The ridge tile shall be correctly covered, evenly spaced, and tightly sealed. The surplus cement mortar shall be cleaned and the contaminated tile surface shall be cleaned with a sponge. The overlap between the ridge tile and the mortar shall be painted with a paint of similar tile color. The ridge of the roof shall be straight without fluctuation. 9. The cornice board must be nailed tightly against the wall without any gap. The horizontal length of the cornice (from the cornice strip to the wall, that is, the width of the cornice board) is 30cm in front of the dormer window, and 40cm in other general cases. "
