Description

Technical Field

[0001] The utility model belongs to the technical field of parapets and relates to a protection structure for the flashing waterproof coiled material of a parapet. Background Technique

[0002] A parapet is a low wall around the roof of a building. In addition to maintaining safety, its main function is also to make a waterproof termination on the parapet to prevent the waterproof layer from seeping water or the rainwater on the roof from overflowing. The function of the parapet on a walkable roof is to protect the safety of personnel and play a decorative role in the building facade. The function of the parapet on a non-walkable roof, in addition to the decorative role of the facade, also fixes the asphalt felt. The parapet is erected perpendicular to the roof of the building. To avoid cracks at the horizontal and vertical intersection points, it is necessary to extend a section of the waterproof layer of the roof to continuously cover the intersection point and the parapet. This kind of anti-leakage design is called flashing. Before laying the waterproof layer, it is also necessary to plaster and level the horizontal and vertical interfaces first, then lay an additional waterproof layer, and finally cover the waterproof layer on the vertical surface and the joint.

[0003] Generally, waterproof coiled materials are used for the waterproof layer. Waterproof coiled materials are mainly used for building walls, roofs, tunnels, roads, landfills, etc., and can play a role in resisting the leakage of external rainwater and groundwater. Waterproof coiled materials are a kind of flexible building materials that can be curled into rolls. As a leak-free connection between the project foundation and the building, it is the first barrier for the waterproofing of the entire project and plays a crucial role in the entire project.

[0004] Due to the poor painting performance of the waterproof coiled material, the protective layer of the waterproof coiled material on the parapet is prone to falling off, making the waterproof coiled material directly exposed, resulting in waterproof failure and the aging of the coiled material due to sunlight exposure.

[0005] The common method for waterproof termination is as follows: Reserve a 20*60mm groove on the parapet at the waterproof termination part, the distance from the groove to the roof height ≥ 250 mm. After the waterproof coiled material is put into the groove, the end of the waterproof coiled material is fixed with cement nails, and at least two points of each waterproof coiled material are fixed. The joint is sealed with waterproof ointment. Waterproof ointment is not an environmentally friendly material, and the toxicity contained in it will cause certain harm to the human body. Therefore, during the construction process, it is necessary to take preventive measures as much as possible to avoid inhaling too much gas and causing harm.

Therefore, it should not be construed as a limitation to the present utility model. The terms "connected", "connected to", and "arranged" used in the present utility model should be understood in a broad sense. For example, it can be a fixed connection or a detachable connection; it can be directly connected or indirectly connected through an intermediate component; it can be a wired connection, a radio connection, or a wireless communication signal connection. For those of ordinary skill in the art, the specific meanings of the above terms can be understood according to specific circumstances.

[0042] Please refer to Figures 1-3 , the present utility model provides the following technical solutions: a flashing waterproofing membrane protection structure for a parapet, comprising: a parapet 2, a waterproofing membrane, and a fastening mechanism. The parapet 2 is a low wall around the roof of a building, such as Figure 1As shown, the parapet wall 2 is vertically located at the top of the building floor slab 1, which can protect the people on the floor slab 1 and also play a decorative role for the building. An installation groove 4 is formed on the inner wall of the parapet wall 2, and the specific position of the installation groove 4 can be freely set according to the actual construction needs on site. The waterproof coiled material covers the top of the floor slab 1 and extends to the parapet wall 2. The fastening mechanism is used to plug the end of the waterproof coiled material into the installation groove 4 of the parapet wall 2, that is, one end of the fastening mechanism and the end of the waterproof coiled material are squeezed in the installation groove 4, thus realizing the waterproof termination and preventing the waterproof coiled material from slipping off the parapet wall 2 and avoiding the leakage phenomenon at the root of the parapet wall 2. In this application, the fastening mechanism is used to fix the end of the waterproof coiled material on the parapet wall 2 to realize the flashing construction of the parapet wall 2. No toxic gas will be generated during the construction process, which is both environmentally friendly and safe and will not cause harm to the bodies of construction workers.

[0043] As a preference of the above embodiment, in this embodiment, the waterproof coiled material near the root of the parapet wall 2 is recessed downward to form a water collecting trough 3, and preferably the water collecting trough 3 is U-shaped. A drain pipe 13 is installed in the floor slab 1, and one end of the drain pipe 13 extends upward to the water collecting trough 5. The water collecting trough 5 and the drain pipe 13 form a funnel-shaped structure, which can reduce the generation of vortices and improve the drainage volume. When it rains, the water collecting trough 3 can collect the rainwater above the waterproof coiled material together and quickly divert it into the drain pipe 3, so that the rainwater is discharged to the outside along the drain pipe 13, thus avoiding the coating of the waterproof coiled material falling off due to long-term soaking of the rainwater.

[0044] Refer to Figure 1 As shown, the above-mentioned fastening mechanism includes: an L-shaped cover plate 8. The end of the waterproof coiled material is located below the installation groove 4 of the parapet wall 2. The horizontal plate of the L-shaped cover plate 8 is located above the installation groove 4 of the parapet wall 2, and at the same time, the L-shaped cover plate 8 presses on the waterproof coiled material, that is, the horizontal plate of the L-shaped cover plate 8 and the end of the waterproof coiled material fill the installation groove 4, so as to prevent the waterproof coiled material from slipping off the parapet wall 2. Preferably, the horizontal plate of the L-shaped cover plate 8 and / or the end of the waterproof coiled material are adhesively bonded to the inner wall of the installation groove 4 through a sealant 9, so as to fixedly connect the horizontal plate of the L-shaped cover plate 8 and / or the end of the waterproof coiled material with the inner wall of the installation groove 4 together.

[0045] In order to shield the parapet wall 2 from rain, the fastening mechanism further includes: a vertical plate 11, a coping 10 and a wall nail 12. The coping 10 is located at the top of the parapet wall 2, and at the same time, the top of the coping 10 is inclined. Figure 1In the shown picture, the coping 10 slopes from the upper right to the lower left, so that the coping 10 can shelter the top of the parapet wall 2 from rain and lead the rainwater into the water collecting trough 3. The vertical plate 11 is attached to the parapet wall 2 and can shelter the upper part of the parapet wall 2 from rain. One end of the vertical plate 11 is in contact with the upper surface of the horizontal plate of the L-shaped cover plate 8, and the other end of the vertical plate 11 is in contact with the bottom of the coping 10, that is, the vertical plate 11 is stuck between the coping 10 and the L-shaped cover plate 8. In this way (since the gravity of the coping 10 is mainly borne by the parapet wall 2 and the downward pressure of the coping 10 on the vertical plate 11 can be ignored), the vertical plate 11 presses down the L-shaped cover plate 8, and then the L-shaped cover plate 8 presses down the waterproof coiled material. The total gravity of the vertical plate 11 and the L-shaped cover plate 8 acts on the waterproof coiled material, which can prevent the waterproof coiled material from warping up from the parapet wall 3 and improve the fitting degree between the waterproof coiled material and the parapet wall 2. The wall nail 12 is used to connect the vertical plate of the L-shaped cover plate 8 and the vertical plate 11. At the same time, nailing the wall top 12 on the vertical plate 11 can reduce the damage to the parapet wall 2. Preferably, the width of the coping 10 is not less than the sum of the width of the vertical plate of the L-shaped cover plate 8, the width of the vertical plate 11 and the width of the parapet wall 2 (here, the parapet wall 2 outside the installation groove 4 is pointed out, which can also be understood as the maximum width of the parapet wall). The bottom of the coping 10 bulges downward to form a drainage eaves. In Figure 1 the shown picture, the drainage eaves is located at the lower left of the coping 10 and has the function of draining water.

[0046] Furthermore, the height of the vertical plate of the L-shaped cover plate 8 is less than the height of the vertical plate 11, which is convenient for construction. The top of the vertical plate of the L-shaped cover plate 8 is inclined outward. In Figure 1 the shown picture, the top of the vertical plate of the L-shaped cover plate 8 slopes from the upper right to the lower left, which is convenient for drainage; and / or the width of the horizontal plate of the L-shaped cover plate 8 is greater than the length of the waterproof coiled material bent towards the installation groove 4. In this way, the L-shaped cover plate 8 can shelter the waterproof coiled material from rain. A chamfer is provided at the bottom of the horizontal plate of the L-shaped cover plate, which can prevent the surface of the waterproof coiled material from being knocked during construction. Preferably, as shown in Figure 2 the figure, the vertical plate 11 and the horizontal plate of the L-shaped cover plate 8 are connected by a sealant 9. The sealant 9 plays a sealing role and can prevent rainwater from penetrating into the gap between the vertical plate 11 and the L-shaped cover plate 8.

[0047] As an embodiment of the specific structure of the above waterproof coiled material, in this embodiment, the waterproof coiled material includes: a waterproof coiled material matrix 5, an adhesive mesh layer 6, and a surface coating 7. Asphalt 16 is filled between the waterproof coiled material matrix 5 and the top plate 1 for fixing the waterproof coiled material matrix 5 on the floor slab 1. The adhesive mesh layer 6 (such as a steel mesh, alkali-resistant fiberglass mesh cloth, etc. When using a steel mesh, the general specifications are a spacing of 12.5*12.5 and a thickness of 0.9 mm, which can be flexibly set according to actual needs) covers the outer wall of the waterproof coiled material matrix 5. The surface coating 7 (such as cement mortar) is laid on the outer wall of the adhesive mesh layer 6. The adhesive mesh layer 6 provides an attachment surface for the surface coating 7, preventing it from falling off easily and also resisting cracking of the surface coating 7.

[0048] Referring to Figure 3 As shown, a sealing filler 15 is provided between the drain pipe 13 and the floor slab 1, and the sealing filler 15 prevents rainwater from entering the gap between the drain pipe 13 and the floor slab 1. The drain pipe 13 is detachably connected to a floor drain 14, so that the floor drain 14 can be taken out from the drain pipe 13 for easy cleaning and replacement. The floor drain 14 communicates with the inner cavity of the water collection tank 3, and sundries mixed in the rainwater can be discharged through the floor drain 14. Specifically, the floor drain 14 includes: an outer extension ring 141, a filter screen 142, and a connecting pipe 143. Among them, the diameter of the outer extension ring 141 is larger than the diameter of the drain pipe 13. The filter screen 142 is fixedly located inside the outer extension ring 141, and the specifications of the filter screen 142 can be selected according to actual needs. One end of the connecting pipe 143 is connected to the bottom of the outer extension ring 141, and the other end of the connecting pipe 143 is movably located inside the drain pipe 13. During installation, the connecting pipe 143 in the floor drain 14 is inserted into the drain pipe 13, and the outer extension ring 141 is located at the top of the drain pipe 13. It should be noted that an installation hole for the drain pipe 13 needs to be reserved in the waterproof coiled material.
