Description

Technical Field

[0001] The invention relates to the technical field of roof construction, in particular to a construction method of a modern traditional style wooden structure tile roof. Background Art

[0002] Ancient Chinese architecture is an important part of Chinese traditional culture, and its architectural color art is its most distinctive part. It always exudes magical charm, and through the historical development process of more than two thousand years, the understanding and application of ancient architecture has been continuously deepened. Traditional style wooden structure tile roofs are also often used in modern buildings to create a unique architectural style. However, there are many problems with the existing wooden structure tile roof construction methods.

[0003] In some large-scale modern traditional style antique buildings, temples, gardens and other projects, traditional thatching technology is used. With the development of modern material science and construction technology, some new materials and technologies are gradually applied to thatching. Despite the application of new materials, some materials still have some problems in actual use. For example, some new waterproof membranes are not compatible with traditional thatching materials, and are prone to delamination and peeling.

[0004] When laying tiles on the roof behind the thatch, due to the large inclination angle of the steep roof, the stability of the construction workers is poor when operating on it. At the same time, the steep slope makes the tiles more susceptible to gravity and wind force, making them prone to slipping and shifting. The traditional fixing method may not meet the requirements of steep roofs, resulting in loose fixing of tiles and potential safety hazards. Summary of the invention

[0005] The purpose of the present invention is to provide a construction method of a modern traditional style wooden structure tile roof, provide tiles and a laying method of tiles, increase the connection stability between tiles, and at the same time, avoid tiles slipping when laying tiles on a roof with a large slope.

[0029] The loess should be from deeper strata with uniform color and should be from the same stratum in the same area. The loess should be sieved before use to remove foreign impurities and larger loess particles to avoid inconvenience in construction caused by failure of moisture to fully penetrate during steaming. The steaming time should be no less than 2 days.

[0030] White lime is made by slaking quicklime with water and passing it through a fine sieve, and it should be simmered for 15 days before use.

[0031] Blue ash is the small mud brick powder after fine sieving.

[0032] The preservative includes one or more of asphalt oil, linseed oil, tung oil and mineral oil.

[0033] The additives include one or more of nano silicon dioxide, nano titanium dioxide, hemp blades, polypropylene fiber, wood fiber particles, bamboo fiber, wheat straw, cellulose ether and linseed oil.

[0034] The length of hemp knife should be not less than 80mm. It should be wetted with clean water one day in advance to make it thoroughly moist. Before use, it should be fluffed and shaken to remove impurities.

[0035] Wheat straw should be smoothed with lime water, piled up and smoldered until it becomes soft before use. It is advisable to flatten the wheat straw with an axe before pouring lime water.

[0036] Example 1 like Figure 1 As shown, the present invention provides a construction method of a modern traditional style wooden structure tile roof, comprising the following steps: S1. Re-lay the lookout boards that have been impregnated with preservative (mineral oil and fish oil mixed in a volume ratio of 1:1) on the roof, use hemp putty to fill the gaps between adjacent lookout boards, and evenly apply preservative (linseed oil and tung oil mixed in a volume ratio of 1:1) on the lookout boards.

[0037] S2. Apply 10-20mm thick protective plate ash on the lookout board and dry it in the sun for no less than 8 hours after application.

[0038] In S2, the guard plate ash includes white ash, blue ash and additives mixed in a mass ratio of 100:8:3, and the additives are nano-silicon dioxide, hemp knife and linseed oil.

[0039] After the guard plate mortar in S3 and S2 is slightly dry, the plaster back is applied layer by layer. After each layer of plaster is applied, it is dried, polished and compacted. The thickness of each layer of plaster back is not more than 50mm. When it is dried to 70% to 80% dry, it is patted with an iron round apricot paddle; In S3, the plaster backing includes lime and loess mixed in a mass ratio of 1:3.

[0040] In S3, when applying the plaster back, the eaves and ridges can be slightly thinner. When the plaster back at the middle waist section is too thick, the tiles can be turned upside down on the guard plate to reduce the roof load.

[0041] After the plaster backing in S4 and S3 is completely dry, the green ash backing is applied, and between the plaster backing and the green ash backing, the hemp knife ash or hemp knife moon white ash is applied. The thickness of each layer of green ash backing shall not exceed 30mm. After each layer of green ash backing is applied, it shall be repeatedly rolled to make it solid before applying the next layer. After each layer of green ash backing is applied, the surface shall be patted with hemp knife before applying the next layer. When the green ash backing is 80% dry, the hemp knife shall be glued and the crutch shall be tied. No one is allowed to go on the green ash backing or stack materials during the drying process.

[0042] In S4, the blue-ash backing includes white ash, blue-ash and additives mixed in a mass ratio of 100:8:3, and the additives are wood fiber particles, bamboo fiber and linseed oil. The surface of the blue-ash backing should be free of ash bursting, cracking, hollowing, water accumulation, alkali brittleness and freezing. The surface should not be cracked, and there should be no roughness such as hemp knife group, exposed hemp, fluffing, blistering, water marks, etc. The slurry must be firm when brushing and rolling, and there should be no excessive tenderness or softness.

[0043] In S4, the method of making the crooks is to use a wooden stick with a semicircular tip to make several round shallow holes on the back of the green ash. Every five of them form a group of crooks in the shape of a plum blossom, and the crooks in each group must be made of hemp. In some buildings, it is also possible to only make the crooks without sticking hemp.

[0044] The newly covered mortar and blue mortar backing should be covered in time when it rains to prevent rain from washing away. The contact surface between the ladder board (soft ladder) used for thatching and the mortar backing should not have nail tips or other hard objects that can easily scratch the mortar backing.

[0045] S5. After removing the loose particles on the back of the blue-gray, apply the interface agent. After drying, apply the nano-composite waterproof coating in the same direction. After drying, apply the second coat of nano-composite waterproof coating in a direction perpendicular to the last coat. The amount of nano-composite waterproof coating is 1.2kg / m². Naturally cure for 48 hours to obtain a nano-composite waterproof layer.

[0046] S6. Apply a flame retardant coating base layer (1 mm) evenly on the nano waterproof layer obtained in S5. The coating direction is the same as the second coating direction of the nano composite waterproof coating. After the flame retardant coating base layer is dry, apply a flame retardant coating surface layer (2 mm) in a direction perpendicular to the flame retardant coating base layer. After drying and curing at room temperature, a flame retardant layer is obtained.

[0047] S7. Apply shoulder putty on the ridge, lay tile strips and tiles on the flame retardant layer, connect the installation hole in the center of the tile with the corrosion-resistant steel wire on the tile strip, and connect the tiles with each other through installation blocks and installation grooves. Set anti-fall block on the roof at the bottom tile. After all are laid, grab the joints and clamp the ridges, and apply it tightly.

[0048] In S7, shoulder mortar is to tie a horizontal line on the ridge line where the two slopes intersect. The ridge bottom is based on this line and plaster is applied along the line on the ridge. The plastering height is level with the horizontal line and the plastering width is 300-500mm. Both sides of the horizontal line are vertically placed on the mortar back of the front and rear slopes.

[0049] Example 2 like Figure 3 As shown, in Example 1, a plurality of mounting blocks 2 are provided on one side of the top of the tile 1, and a plurality of mounting grooves 3 are provided on one side of the bottom of the tile 1, and the mounting blocks 2 are connected with the mounting grooves 3. A water hole 4 is provided at the bottom of the mounting groove 3, and the mounting grooves 3 are connected through the mounting blocks 2, so that when adjacent tiles 1 are laid, the tiles 1 are prevented from sliding on a roof with a large slope, and the safety of the tiles 1 after laying is increased. The provision of the water hole 4 prevents rainwater from accumulating in the mounting groove 3.

[0050] like Figure 2 As shown, according to the spacing of the tile hanging strips 7 set on the roof, when the tile 1 is laid on the flame retardant layer, the mounting hole 5 in the center of the tile 1 is connected to the corrosion-resistant steel wire 8 on the tile hanging strip 7. The tiles 1 are connected to each other through the mounting blocks 2 and the mounting grooves 3, and an anti-drop block 6 is set on the roof at the bottom of the tile 1. The height of the anti-drop block 6 is lower than the horizontal height of the concave surface of the tile 1, which ensures that the tile 1 can drain water smoothly and prevents the tile 1 from sliding off.

[0051] like Figure 4 and Figure 5 As shown, corrosion-resistant steel wires 8 are connected between adjacent tile hanging strips 7, corrosion-resistant steel wires 8 are hung on the ridge to cross the ridge, and the tile hanging strips 7 on both sides of the ridge are connected to the corrosion-resistant steel wires 8. Then, the corrosion-resistant steel wires 8 pass through the mounting holes 5 to connect the tile hanging strips 7 with the tiles 1, thereby increasing the tightness of the connection between the tiles 1 and the tile hanging strips 7, reducing the gap between the two, improving the waterproof performance, and preventing the tiles 1 from sliding off the roof.

[0052] Example 3 The method for preparing the nanocomposite waterproof coating in S5 in Example 1 comprises the following steps: T1. Weigh 70 parts of water-based acrylic emulsion, 1 part of nano-silane, 0.5 parts of nano-silicon dioxide, 0.5 parts of nano-zinc oxide, 2 parts of nano-fluorocarbon, 1 part of dispersant and 3 parts of plasticizer (citrate ester) by mass.

[0053] T2, mixing the aqueous acrylic emulsion and the dispersant, stirring at 300 rpm / min for 8 min, adding nano-fluorocarbon, nano-silicon dioxide and nano-zinc oxide in sequence, stirring at 900 rpm / min for 25 min until the mixture is evenly dispersed, and grinding to obtain a nanoparticle dispersion system; T3, at 300rpm / min, slowly add nano-silane to the nano-ion dispersion system in T2, stir until the nano-silane and the nano-ion dispersion system are evenly mixed, and continue to add plasticizer (citrate esters) under stirring to obtain a nano-composite waterproof coating.

[0054] Therefore, the present invention adopts a construction method of a modern traditional style wooden structure tile roof using the above steps, using a compound additive to reduce the porosity of the lime mortar and increase the tensile strength, toughness and adhesion.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that they can still modify or replace the technical solution of the present invention with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of the present invention.
