Abstract
Description
Technical Field
[0001] The invention relates to the technical field of building construction, in particular to a simple construction method for an exhaust duct of a large roof insulation layer. Background Art
[0002] Roof structures are divided into upright roofs and inverted roofs. The upright roof consists of a structural layer, a leveling layer, an insulation layer, a mortar leveling layer, and a waterproof layer from bottom to top. The insulation layer is set below the waterproof layer. In order to discharge the water vapor accumulated between the insulation layer and the mortar leveling layer, thereby preventing the membrane from cracking, bulging, and other damages, a criss-cross exhaust duct must be set in the insulation layer of the upright roof.
[0003] The common exhaust duct is the left-pipe exhaust duct, such as Figure 1 , Figure 2 As shown, this type of exhaust duct 2 is arranged in a mesh within the roof boundary 1, and it is necessary to purchase a φ25-φ32 plastic pipe 8. In order to ensure that the exhaust duct can effectively collect water vapor, it is also necessary to use a hand drill on site to drill dense small holes on the exhaust duct to form a collection flower pipe; This type of exhaust duct requires the purchase of pipe materials separately. When performing large-area hole-turning processing, the construction period may be delayed and work may be delayed. The drilling workload of the collection flower pipe is large. During on-site processing, workers may be easily injured when operating flashlights. At the same time, the waterproof leveling layer applied above the insulation layer is mortar, which has fluidity and will enter the exhaust duct through the small holes, causing the exhaust duct to be blocked. Therefore, a simple construction method for the exhaust duct of the large roof insulation layer is proposed. Summary of the invention
[0004] The present invention aims to solve the above problems, thereby providing a simple construction method for the exhaust duct of a large roof insulation layer.
[0005] The present invention solves the above-mentioned problem by adopting the following technical solution: A simple construction method for the exhaust duct of a large roof insulation layer is carried out according to the following steps: Step 1: After the construction of the structural layer and the leveling layer is completed, the wood planks are arranged according to the designed exhaust duct line. The wood planks can be made of the remaining wood from the main structure construction stage; Step 2: construct the insulation layer and mortar leveling layer; lay the insulation board on the leveling layer, clamp the insulation board tightly around the wood, and after laying the insulation board, spread the mortar over a large area to make the mortar leveling layer; the insulation board clamps the wood to prevent the wood from moving when spreading the mortar; Step 3: Dig out the wood to form a spacing groove; after the mortar leveling layer has finally set and reached 5MPa, dig out the wood; when digging out the wood, avoid damaging the edges and corners of the mortar and protect the finished product; Step 4: Lay fine stones in the spacing grooves; spread the fine stones in the spacing grooves on site. After laying the fine stones, scrape the upper surface flat to the same height as the mortar leveling layer; Step 5: Construction of waterproof layer and air vents; Lay waterproof membrane over a large area. Before laying the waterproof membrane, evenly distribute several ventilation pipes above the spacing grooves.
[0006] Furthermore, before the waterproof layer is constructed, an additional waterproof layer is laid on top of the fine stones, and the width of the additional waterproof layer is greater than the width of the spacing groove to prevent the fine stones from breaking the main waterproof layer.
[0007] Furthermore, in step one, the size of the wood should be determined in advance, with the width equal to the designed width of the exhaust duct and the height exceeding the designed elevation of the mortar leveling layer.
[0008] Furthermore, in step 4, the particle size of the fine stone should be 10-25 mm to ensure the porosity.
[0009] Compared with the prior art, the present invention adopting the above technical solution has the following outstanding features: Use existing materials on site to save construction costs. Fine stone and wood are common materials on the construction site, and there is enough surplus material, so there is no need to purchase plastic round pipes separately and spend construction expenses.
[0010] Eliminate the need for on-site electric drill drilling, reducing safety hazards. Use fine stones in the spacing groove instead of collecting flower tubes, do not use a flashlight to operate, and reduce the risk of injury to workers when using electric drills.
[0011] Avoid blockage of the exhaust duct and improve the quality of construction. Fine stones are used to fill the interval grooves. There are a lot of gaps between the fine stones, which can meet the needs of water vapor circulation; at the same time, the fine stones play a role in supporting the additional waterproof layer, and the additional waterproof layer plays a role in preventing the fine stones from breaking the main waterproof layer.
[0012] The on-site operation is simple and convenient, which significantly improves the project efficiency. On-site workers pour fine stones into the spacing grooves and flatten the upper surface, and waterproof workers cover the upper surface with roll materials. The construction is fast, simple and effective. It can shorten the original on-site construction time by more than 90% and significantly reduce the on-site installation workload.
