Description

Technical Field

[0001] This utility model relates to the field of floor waterproofing technology, specifically a waterproof structure for the connection point of prefabricated walls, floors and precast balconies. Background Technology

[0002] Prefabricated construction refers to transferring a large amount of on-site work from traditional construction methods to factories. Building components and accessories (such as floor slabs, wall panels, stairs, balconies, etc.) are prefabricated in factories, transported to the construction site, and assembled on-site using reliable connection methods. However, in actual installation, joints often exist between prefabricated balcony / exterior wall panels and floor slabs. If water accumulates on the balcony, it can easily seep into the floor below through these joints. The usual solution is to install waterproofing measures at the joints. However, existing waterproofing measures generally use waterproof gaskets at the joints, but simply using waterproof gaskets is not very effective and allows water to easily seep in. Therefore, improvements are urgently needed.

[0003] Application number CN202122051046.4 discloses a waterproof structure for the connection between a prefabricated floor slab and a precast balcony, including a balcony slab, and an upper floor slab and a lower floor slab respectively snapped onto the upper and lower ends of the balcony slab; a water collection trough is provided on the upper floor slab, an upper fastening block is provided at the bottom of the upper floor slab, an upper snap-fit ​​groove is provided at the bottom of the upper fastening block, and a waterproof pad is provided in the upper snap-fit ​​groove; a lower fastening block is provided at the top of the lower floor slab, a lower snap-fit ​​groove is provided at the top of the lower fastening block, and a waterproof pad is also provided in the lower snap-fit ​​groove; a drainage pipe communicating with the outside is provided inside the balcony slab, and a drainage pipe communicating with the water collection trough is provided on the upper fastening block, with the outlet end of the drainage pipe penetrating through the surface of the balcony slab and communicating with the drainage pipe.

[0004] The aforementioned prior art can absorb water by setting up a waterproof pad, but it is difficult to prevent water seepage from the floor slab from entering the balcony using the waterproof pad. Utility Model Content

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This utility model discloses a waterproof structure for the connection point of prefabricated walls, floors, and precast balconies. During operation, a water-resistant component is installed to drain water from the floor slab, preventing it from seeping into the balcony slab on the next floor. Furthermore, an L-shaped waterproof gasket reduces rainwater seepage into the wall at the connection point. Even if water does seep into the wall, it is drained into a drainage channel through the drainage holes, thus preventing prolonged water infiltration within the wall and improving the waterproofing effect.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example:

[0024] Please see Figures 1 to 4 This utility model provides a technical solution:

[0025] A waterproof structure for the connection point of prefabricated walls, floors, and precast balconies includes a wall 1, a balcony slab 2, a waterproof component 3, a waterproof board 4, a waterproof pad 5, and a floor slab 6, wherein:

[0026] Balcony slab 2 and floor slab 6 are located on both sides of wall 1. Wall 1 is connected to balcony slab 2 and floor slab 6 through waterproof component 3. The upper and lower walls 1 are connected to waterproof component 3 by cement pouring. Waterproof component 3 is connected to balcony slab 2 by cement pouring. Waterproof component 3 is connected to floor slab 6 by cement pouring.

[0027] A water-proof board 4 is provided at the connection between the balcony slab 2 and the floor slab 6, and a waterproof pad 5 is provided between the water-proof component 3 and the balcony slab 2 and the floor slab 6.

[0028] In a preferred embodiment, the waterproofing component 3 includes a connecting plate 31, a drainage channel 32, and a water pipe 33. One end of the connecting plate 31 is fitted onto the wall 1, and the other end is secured to two balcony slabs 2. A waterproof gasket 5 is provided at the connection point between the connecting plate 31 and the balcony slabs 2. The connection is then reinforced with cement. The connecting plate 31 has a drainage channel 32, which collects water seeping into the wall 1. One end of the water pipe 33 is connected to the outlet of the drainage channel 32, and the other end serves as the outlet on the outside of the wall 1. The water pipe 33 drains water from the drainage channel 32. By installing the waterproofing component 3, water from the wall 1 can be drained through the waterproofing component 3, preventing water from seeping into the balcony slabs 2.

[0029] In a preferred embodiment, the guide channel 32 is higher at the perimeter and lower at the center, with the center of the guide channel 32 serving as the water outlet. This configuration of the guide channel 32 allows water within it to be collected at the central outlet, thereby achieving rapid drainage.

[0030] In a preferred embodiment, the waterproof component 3 further includes an L-shaped waterproof pad 34 and drainage holes 35. The L-shaped waterproof pad 34 is disposed between the connecting plate 31 and the wall 1 and is located on one side of the balcony slab 2. The L-shaped waterproof pad can reduce rainwater seepage into the wall from the connection between the wall and the waterproof component during rainy days. The connecting plate 31 has drainage holes 35 arranged in an array on one side of the balcony slab 2. The inlet of the drainage holes 35 is located at the connection between the connecting plate 31 and the wall 1, while the outlet faces the drainage channel 32. The drainage holes 35 can drain water seeping from the connection between the wall and the waterproof component into the drainage channel 32.

[0031] In a preferred embodiment, the balcony slab 2 has protrusions, and the floor slab 6 has grooves. The balcony slab 2 and the floor slab 6 are connected by the protrusions and grooves. This arrangement increases the connection strength between the balcony slab 2 and the floor slab 6, preventing water on the balcony slab 2 from seeping into the floor slab.

[0032] As a preferred embodiment, a one-way valve 36 is provided on the water pipe 33 to prevent water from flowing back into the wall from the water pipe 33.

[0033] The working principle of this utility model:

[0034] When this device is in use, if water seeps into the wall 1, the water will accumulate in the diversion channel 32, and the water in the diversion channel 32 can be discharged from the water pipe 33.

[0035] When rainwater flows into the connection between the wall and the waterproof component during rainy days, the water can be drained into the drainage channel through the drainage holes, thus preventing rainwater from seeping into the wall for a long time and improving the waterproof effect.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
