Description

Technical Field

[0001] This utility model relates to the field of building repair technology, specifically to a drip edge structure for waterproofing a traditional Tibetan rammed earth roof. Background Technology

[0002] In some parts of Tibet, traditional dwellings use rammed earth (aka tu) to form earthen roofs. The ramming technique of aka tu is also called "da aga" and is known as "the dance on Tibetan construction sites." It is a traditional craft for building Tibetan-style roofs or interior floors.

[0003] However, due to the lack of effective waterproofing design in the roofs of traditional dwellings in some parts of Tibet, serious water seepage and leakage problems exist in the rammed earth roofs of these traditional houses. In particular, most traditional houses use unorganized drainage systems, meaning rainwater flows freely outwards from the roof. Due to the Coanda effect, this unorganized drainage can cause water to flow down the eaves and into the wooden roof structure or walls. This not only erodes the wooden roof structure, causing cracks and damaging interior paintings, but also erodes the rammed earth walls, threatening some with collapse. This problem not only affects the daily lives and production of the local Tibetan people but also poses a challenge to the protection and inheritance of their precious cultural heritage.

[0004] The main reasons are: 1. In an unorganized drainage system, rainwater has no fixed drainage pipes to guide it, and its flow path is relatively free, which increases the difficulty of waterproofing the eaves; in particular, roofs made of rammed earth without proper slope or finishing treatment are prone to leakage problems.

[0005] 2. When the drainage system is not organized, the water will flow down the eaves into the surface layer or the wood structure layer, causing water seepage at the edges, which will damage the wood structure layer in the long run.

[0006] 3. In the event of unorganized drainage, water will flow down the eaves to the wall, which will damage the rammed earth wall over time.

[0007] Therefore, the current waterproofing methods for rammed earth roofs cannot meet the requirements. Utility Model Content

[0008] This utility model discloses a TPO waterproof membrane combined with an eaves drip structure for an Aga rammed earth roof, which aims to improve the problem of easy leakage or seepage at the roof and edges of existing Aga rammed earth roofs.

[0009] The present invention adopts the following solution:

[0010] The eave drip structure of a TPO waterproof coiled material combined with an argali rammed earth roof comprises a roof wood structure layer, a waterproof layer formed by laying a TPO waterproof coiled material above the roof wood structure layer, and an argali rammed earth surface layer above the waterproof layer; the TPO waterproof coiled material extends outside the edge of the roof wood structure layer and is connected with a skirt-type drip structure suitable for guiding flow at the eave.

[0011] Further, the skirt-type drip structure is fixedly connected to the edge of the waterproof layer by hot air welding.

[0012] Further, the skirt-type drip structure comprises a connecting portion suitable for connecting the waterproof layer and a drip portion extending out of the eave and downwardly inclined, and the drip portion comprises a plurality of drip tips arranged at intervals.

[0013] Further, an arc-shaped flow guiding portion is arranged between the drip portion and the connecting portion.

[0014] Further, the waterproof layer extends to the eave of the roof wood structure layer and is bent downwardly at the eave to cover the side surface of the roof wood structure layer, and the skirt-type drip structure is arranged above the upper side of the waterproof layer.

[0015] Further, the skirt-type drip structure is made of TPO waterproof coiled material.

[0016] Beneficial effects:

[0017] The present scheme sets the TPO waterproof coiled material as the main waterproof layer, and the TPO waterproof coiled material has very high quality and high flexibility, high temperature resistance, weather resistance, corrosion resistance, and easy repair. The skirt-type drip structure arranged at the eave is above the waterproof layer, can guide the water flowing out of the waterproof layer, and can drip along the skirt-type drip structure, improve the hydrophobic efficiency, and prevent the roof rainwater from flowing back to the wood structure and the rammed earth wall, thereby further protecting the safety of the building structure.

[0023] Combined Figures 1 to 4 As shown in the embodiment, a kind of TPO waterproofing membrane combined with the eaves 5 drip structure of gat soil rammed earth roof is provided, including roof wood structure layer 1, the waterproof layer 2 of TPO waterproofing membrane laying is arranged in the upper of roof wood structure layer 1, the modified gat soil surface layer 4 is arranged in the upper of waterproof layer 2;The TPO waterproofing membrane extends the edge outside of roof wood structure layer 1 and is connected with skirt type drip structure 3 suitable for guiding at eaves 5.

[0024] In the embodiment, the roof wood structure layer 1 is the original wood structure of gat soil rammed earth roof, which is built by wood and board, and the board is placed on the upper of wood, which plays a supporting and stabilizing role.The waterproof layer 2 is laid on the upper of roof wood structure layer 1, specifically, TPO waterproofing membrane can be laid on the upper of board by hot air welding and other ways, so as to form waterproof layer 2.

[0025] The waterproof layer 2 adopts TPO waterproof coiled material. The TPO waterproof coiled material is produced by extrusion method with ethylene-propylene rubber and polypropylene as base material, and adding various modifiers, antioxidants, anti-aging agents and ultraviolet absorbers and other auxiliary materials. The TPO waterproof coiled material can still maintain its physical and chemical properties under direct sunlight, and can withstand a temperature difference range of -40℃ to 100℃. This coiled material shows good adaptability, not only can effectively resist the displacement change caused by the temperature difference between day and night, but also can maintain its excellent flexibility in low temperature environment, and can ensure the stability of mechanical strength even in high temperature conditions, so as to continuously show excellent waterproof effect in various climate conditions. At the same time, the TPO waterproof coiled material is a high-performance waterproof material with excellent hydrophobicity, which can effectively prevent water molecules from penetrating into the material, thereby ensuring the waterproof effect of the roof. The TPO material also has "super hydrophobicity", which can make water form a lotus effect on its surface (lotus effect refers to the fact that the lotus leaf has a hydrophobic and non-absorbing surface, and the rainwater falling on the leaf surface will form water droplets due to surface tension), which can be easily drained with very small slope. Therefore, it is particularly suitable for roof waterproof application in plateau areas. The lap joint of adjacent TPO waterproof coiled material is welded by hot air, the joint peeling strength is high, a safe and reliable waterproof layer 2 is formed; its dense molecular structure and super strong joint strength make it have excellent physical root resistance; when repairing, the TPO single-layer roof only needs to be welded in the form of patching, which is a one-time repair after repair, and the repair cost is much lower than that of metal roof; in addition, with the large use of TPO waterproof coiled material, its price is more and more affordable, and it has very high cost performance after comprehensive comparison.

[0026] In this embodiment, the surface layer 4 is a modified Agat surface layer 4 treated with regional materials. The modified Agat surface layer 4 here refers to mixing crops such as highland barley straw with Agat to enhance the stability and anti-erosion of the roof soil. Highland barley straw is rich in fiber, and the adhesion and plasticity of these fibers combined with Agat or loess can form a network structure. This structure can significantly increase the cohesion and internal friction of the soil, thereby enhancing the cohesion of the soil and forming a more stable soil structure. Using crops such as highland barley straw as a modified material not only has feasibility, but also is a rational use of resources. Specifically, during the construction of the modified Agat surface layer 4, first mix crops such as highland barley straw with Agat or loess in the coarse and medium particle size layer, then tamp the roof in layers, secondly compact the fine particle size Agat or loess after tamping, and finally polish and refine the roof surface layer 4 and perform finishing and maintenance. The traditional process of adding crops such as highland barley straw can significantly improve the compactness of the Agat surface layer 4.

[0027] In combination with Figures 1 to 4As shown, in the embodiment, the skirt-type water dripping structure 3 can be connected to the edge of the waterproof layer 2 by hot air welding. Specifically, the skirt-type water dripping structure 3 includes a connecting part 31 adapted to connect the waterproof layer 2 and a water dripping part extending out of the eave 5 and downwardly inclined, the water dripping part including a plurality of water dripping tips 32 arranged at intervals; and an arc-shaped flow guiding part 33 arranged between the water dripping part and the connecting part 31. Here, the water dripping tips 32 are arranged in a fan shape or a triangular shape, the edge lines are arranged in an arc shape, and the end parts are arranged in a circular arc shape, and the plurality of water dripping tips 32 form a wave shape. The arc-shaped flow guiding part 33 has an arc surface concave toward the eave 5, improves the flow rate, and makes the flow guiding effect better.

[0028] The skirt-type water dripping structure 3 is made of TPO waterproof coiled material, and the skirt-type water dripping structure 3 is formed in a skirt-like shape by hot plastic processing of the TPO waterproof coiled material, and the connecting part 31 of the skirt-type water dripping structure 3 is fixedly connected to the waterproof layer 2 by hot air welding, which has good sealing effect and strong adhesion effect. At room temperature, the TPO waterproof coiled material exhibits high elasticity like rubber, and at high temperature, it can be easily processed like plastic. This excellent plasticity makes it possible to shape the TPO waterproof coiled material into various shapes according to actual needs to meet different waterproofing requirements, such as circular building structures and square building structures. After the TPO coiled material is hot-plasticized into a skirt-like shape, it not only effectively prevents water, but also prevents roof rainwater from flowing back to the wooden structure and rammed earth wall, thereby further protecting the safety of the building structure.

[0029] In the embodiment, the waterproof layer 2 extends to the eave 5 of the roof wooden structure layer 1 and is bent downward at the eave 5 to cover the side of the roof wooden structure layer 1, preventing water from penetrating through the eave 5, and the skirt-type water dripping structure 3 is arranged on the upper side of the waterproof layer 2 to achieve secondary waterproofing at the eave 5 and further prevent water flow from penetrating into the roof wooden structure layer 1.

[0030] In another embodiment, the skirt-type water dripping structure 3 can also be connected to the edge of the waterproof layer 2 by a fixing part, specifically, a fixed connecting strip is arranged to fix the connecting part 31 of the skirt-type water dripping structure 3 to the waterproof layer 2 by cooperating with a screw, and then hot air welding is used for sealing connection.

[0031] In the embodiment, since the waterproof layer is spliced by TPO waterproof coiled material, the lap joint of the TPO waterproof coiled material can be fixedly connected by hot air welding, so that the sealing property of the lap joint is good, the peel strength is high, and a safe and reliable sealing waterproof layer 2 is formed.

[0032] During the construction repair, the Akat layer 4 of the eaves part to be repaired is first excavated, then the waterproof layer 2 is laid on the exposed roof wood structure layer 1, then the skirt type drip structure 3 is fixed at the eaves 5 around, then the mixed Akat and crop straw such as highland barley are re-laid, and the roof is layered and rammed, after the ramming, the fine-grained Akat is again rammed, then the roof surface layer 4 is polished, refined and polished according to the original traditional Akat process.

[0033] Through the scheme, the original roof features and cultural characteristics are retained, the Akat roof non-heritage ramming process is inherited, the excellent waterproof performance is embodied, the respect for regional traditional materials is embodied, the materials used have excellent environmental protection and sustainability, the construction has safety and implementability, the subsequent maintenance has feasibility and convenience, and the like.
