Description

Technical Field

[0001] This application relates to the technical field of building waterproofing, and particularly to a waterproof structure at the wall root of an integrated panel facade. Background Art

[0002] In the traditional construction method for the side wall of a basement or the part where the basement roof meets the upper turning wall root of the main building, a waterproof layer is applied on the structural surface, and a brick protection wall or an extruded polystyrene insulation board protection layer is constructed and then backfilled and compacted. As a result, the connection part between the waterproof layer below the plus / minus zero elevation and the waterproof layer above the plus / minus zero elevation is usually a common area prone to later leakage. Due to reasons such as multi-trade cross-operation during the construction process, the waterproof lap at this part is often not in place. If the exterior facade is of an integrated panel structure, since the exterior wall waterproof layer is between the insulation layer and the coating layer and not on the same vertical plane as the basement waterproof layer, this problem will become more prominent. Therefore, providing a waterproof structure to solve the leakage problem caused by non-lap or incomplete lap of the waterproof layers above and below the plus / minus zero elevation has become an urgent technical problem for those skilled in the art. Utility Model Content

[0003] The purpose of this application is to provide a waterproof structure at the wall root of an integrated panel facade. By setting up the exterior wall waterproof structure and arranging a hardening layer and a bedding mortar layer at the lower end of the integrated panel facade at the wall root, the waterproof layers at the upper and lower parts of the plus / minus zero elevation are completely lapped and water vapor is isolated from entering the exterior wall waterproof layer, thus avoiding leakage. The specific solution is as follows:

[0004] A waterproof structure at the wall root of an integrated panel facade includes an exterior wall, an exterior wall waterproof layer, an integrated panel, and a basement side wall waterproof layer. On the outer side of the exterior wall where the exterior wall waterproof layer above the plus / minus zero elevation and the basement side wall waterproof layer below the plus / minus zero elevation do not lap or incompletely lap, a first waterproof layer and a second waterproof layer are successively coated. A hardening layer is laid closely following the second waterproof layer, and a bedding mortar layer is laid between the hardening layer and the integrated panel.

[0005] Further, the integrated panel is bonded to the exterior wall waterproof layer through an adhesive layer, and the bedding mortar layer is connected and fixed to the lower end of the integrated panel to support the integrated panel.

[0006] Even further, the bedding mortar layer is a slow-setting leak stoppage king.

[0007] Further, the bedding mortar layer, the hardening layer, and the integrated panel are sealed by a sealing layer, or the hardening layer and the integrated panel are sealed by the slurry overflowing from the bedding mortar layer.

[0008] Further, the first waterproof layer is a polyurethane waterproof coating.

[0009] Further, the second waterproof layer is a cement mortar layer with waterproofing agent added, serving as an independent waterproof layer and a protection layer for the first waterproof layer.

[0010] Furthermore, the cross-section of the hardened layer thickness can completely cover the second waterproof layer.

[0011] Furthermore, the surface of the hardened layer inclines away from the integrated board.

[0012] Beneficial effects: Aiming at the water leakage problem caused by the non-lap or incomplete lap of the waterproof layers above and below the plus-minus zero elevation, through the setting of the external wall waterproof structure at the non-lap or incomplete lap of the waterproof layers above and below the plus-minus zero elevation and the setting of the hardened layer and the grouting layer at the lower end of the outer facade of the integrated board at the wall root, the waterproof layers at the upper and lower parts of the plus-minus zero elevation are completely lapped and the water vapor is isolated from entering the external wall waterproof layer. The structure is simple and the waterproof effect is good. Description of the Drawings

[0014] Figure 2 It is a partial enlarged view of the wall root waterproof structure of the outer facade of the integrated board in this application. Detailed Embodiment

[0015] Next, the technical solutions in the embodiments of this application will be clearly and completely described in conjunction with the drawings of this application. Obviously, the described embodiments of this application are only partial embodiments of this application, rather than all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of this application. The following describes this application in detail with reference to the drawings. It should be noted that the integrated board in this application is a thermal insulation coating waterproof integrated board, and the leak stoppage king is a product purchased on the market.

[0016] As Figure 1 shown, a wall root waterproof structure of an integrated board outer facade includes an external wall 6, an external wall waterproof layer 7, an integrated board 9, and an underground side wall waterproof layer 10.

[0017] Before construction, a position for the integrated board 9 is reserved within 1 m of the lower part of the external wall 6.

[0018] As Figure 2As shown, a first waterproof layer 1 and a second waterproof layer 2 are successively coated on the outer side of the exterior wall 6 where the exterior wall waterproof layer 7 above the plus-minus zero elevation and the underground side wall waterproof layer 10 below the plus-minus zero elevation do not overlap or do not completely overlap. The first waterproof layer 1 is a polyurethane waterproof coating with a thickness of 2 mm. The polyurethane waterproof coating can be directly constructed on various wet or dry base surfaces, has a strong bonding force with the base surface, the polymer substances in the coating film can penetrate into the micro fine cracks of the base surface, the coating film has good flexibility and weather resistance, and has both waterproof and air barrier functions, which is suitable for the construction and application scenarios here. The second waterproof layer 2 is a cement mortar layer with 5% waterproof agent added, which serves as an independent waterproof layer and a protective layer for the first waterproof layer 1.

[0019] Immediately after the second waterproof layer 2, a hardening layer 3 is laid. The thickness cross-section of the hardening layer 3 can completely cover the second waterproof layer 2 to enhance the waterproof effect of the exterior wall 6. The surface of the hardening layer 3 slopes away from the integrated board 9 to prevent water vapor from spreading along the hardening layer 3 to the exterior wall 6.

[0020] After the construction of the hardening layer 3 is completed, a mortar bedding layer 4 is laid on the surface of the hardening layer 3. Specifically, slow-setting leak stoppage king is plastered on the surface of the hardening layer 3 with a thickness controlled at 2 cm.

[0021] Before the mortar bedding layer 4 is laid and the mortar leak stoppage king is not dry and hardened, the integrated board 9 is laid within the 1 m range reserved at the lower part of the exterior wall 6. The integrated board 9 is bonded to the exterior wall waterproof layer 7 through an adhesive layer 8. The lower end of the integrated board 9 is pressed into the leak stoppage king of the mortar bedding layer 4. After the leak stoppage king is dry, the mortar bedding layer 4 is connected and fixed to the lower end of the integrated board 9 to support the integrated board 9.

[0022] When the lower end of the integrated board 9 is pressed into the mortar bedding layer 4, the leak stoppage king slurry is extruded. The overflowing slurry is used to seal the joints of the mortar bedding layer 4, the hardening layer 3 and the integrated board 9, or sealant is applied at the joints of the mortar bedding layer 4, the hardening layer 3 and the integrated board 9 and sealed by a sealing layer 5. This prevents water vapor from entering the exterior wall along the integrated board 9 and the hardening layer 3.

[0023] The wall root waterproof structure on the outer surface of the integrated board in this application is aimed at the water leakage caused by the non-overlap or incomplete overlap of the waterproof layers above and below the plus-minus zero elevation. Through the setting of the exterior wall waterproof structure at the non-overlap or incomplete overlap of the waterproof layers above and below the plus-minus zero elevation and the setting of a hardening layer and mortar bedding waterproof at the lower end of the outer surface of the wall root integrated board, the waterproof layers at the upper and lower parts of the plus-minus zero elevation are completely overlapped and water vapor is isolated from entering the exterior wall waterproof layer. The structure is simple and has a good waterproof effect.
