Technical Field

[0001] The utility model relates to the technical field of building ventilation, in particular to a waterproof civil air-defense air supply shaft. Background Art

[0002] Air supply shafts for civil air defense are vertical shafts reserved in buildings, primarily used for ventilation. Waterproofing these shafts is a key issue, and traditional methods for waterproofing them have numerous drawbacks. Due to collapse prevention requirements, these shafts must be disconnected from the main structure by a seam. Consequently, improper waterproofing often results in poor waterproofing, leading to water leakage into underground structures.

[0003] In response to the above-mentioned deficiencies of existing air supply shafts, this application combines the design, construction and management experience in related fields to provide a waterproof civil air defense air supply shaft to avoid the waterproof drawbacks of existing ventilation shafts. Utility Model Content

[0010] According to the embodiment of the present application, the metal cover plate is fixedly connected to the vertical concrete flap and the building exterior wall using φ8 stainless steel plastic expansion bolts.

[0011] According to an embodiment of the present application, a waterproof layer is further provided at the connection between the vertical concrete flap and the air shaft top plate.

[0012] According to an embodiment of the present application, the leveling and sloping layer is an inclined cement mortar layer.

[0013] According to an embodiment of the present application, the length of the air shaft top plate is longer than the length of the air supply shaft opening.

[0014] According to an embodiment of the present application, a ventilation hole connected to the ventilation chamber is provided on the side wall of the air supply shaft body, and an automatic waterproof shutter is installed on the ventilation hole.

[0015] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0016] The utility model arranges rainproof louvers near the air shaft opening to effectively block rainwater; and a top cover with a leveling and sloping layer is provided above the air shaft opening, so that rainwater will not gather on the top cover when falling from above; at the same time, since the length of the top cover is longer than the air shaft outlet, rainwater will drip from the front end of the air shaft opening and will not affect the air shaft opening; waterproof materials are used to simplify the construction process, reducing manpower and time costs; the metal plate is firmly fixed to the exterior wall and the flap, and no gap is left between the metal plate and the slope and leveling layer, preventing rainwater from seeping in through the gap.

Similarly, terms such as "a" or "an" do not denote a limitation of quantity, but rather denote the presence of at least one.

[0024] according to Figure 1 、 Figure 2 As shown, a waterproof civil air defense air supply shaft as exemplified in the present invention includes an air shaft top plate 1, a leveling and sloping layer, a waterproof layer and a metal cover plate 6. Compared with the problems of complex construction, high cost and poor waterproofing effect of the waterproof method of the air supply shaft in the prior art, the present application simplifies the construction process through a series of designs at the opening of the air supply shaft 3, thereby ensuring the waterproof effect at the junction of the air supply shaft 3 and the main building.

[0025] In this embodiment, the air shaft top plate 1 is arranged at the top of the opening of the air supply shaft 3, and a vertical concrete flap 2 is provided on the side of the air shaft top plate 1 adjacent to the building outer wall 4.

[0026] Specifically, if Figure 1 As shown, the top of the vertical concrete flap 2 is provided with a slope in the shape of a right-angled trapezoid, which makes it easier for rainwater to drain down quickly.

[0027] Specifically, a waterproof layer is provided at the connection between the vertical concrete opening 2 and the air shaft top plate 1. In actual construction, a waterproof layer is added at the corner between the vertical concrete opening 2 and the air shaft top plate 1.

[0028] Specifically, the length of the air shaft top plate 1 is longer than the length of the opening of the supplementary air shaft 3 .

[0029] In this embodiment, a leveling and screed layer is applied to the outer surface of the air shaft roof 1. This layer is an inclined cement mortar layer. Rainwater falling from above does not accumulate on the air shaft roof 1. Furthermore, because the air shaft roof 1 is longer than the air shaft outlet, rainwater drips from the front of the air shaft opening without affecting it.

[0030] In this embodiment, the waterproof layer is coated on the leveling and sloping layer, and the waterproof layer is a double-layer waterproof layer.

[0031] In this embodiment, the metal cover plate 6 is installed at the junction of the vertical concrete flap 2 and the building exterior wall 4.

[0032] Specifically, a waterproof sealant is provided between the metal cover plate 6 and the surrounding structural layers, and waterproof mortar is used to fill the gaps between the metal cover plate 6 and the surrounding structural layers.

[0033] Specifically, the metal plate is slightly higher than the boundary line of the air supply shaft 3 in the horizontal direction.

[0034] Specifically, the metal cover plate 6 is fixedly connected to the vertical concrete flap 2 and the building exterior wall 4 using φ8 stainless steel plastic expansion bolts.

[0035] Specifically, a ventilation hole connected to the ventilation chamber is provided on the side wall of the main body of the air supply shaft 3, and a waterproof shutter 5 is installed on the ventilation hole.

[0036] In this embodiment, the waterproofing method of the air supply shaft 3 is implemented as follows: the top of the reinforced concrete flap of the air shaft adopts a right-angled trapezoid, which is convenient for rainwater to drain down quickly; the air shaft top plate 1 and the flap outer corridor structural plate are cleaned, and cement mortar is used for leveling and sloping; after the waterproof layer is completed, the metal plate is fixed at the same time, and the metal plate and the outer wall and the flap should be firmly fixed, and no gap should be left between the metal plate and the slope and leveling layer. The flatness of the outer wall surface layer and the metal plate must be ensured during the construction of the outer wall; during the waterproofing construction, a waterproof layer is added to the corner of the flap and the concrete slab; the metal plate is slightly protruding from the boundary line of the air shaft in the horizontal direction, and the metal cover plate 6 and the surrounding structural layers are filled tightly with waterproof mortar.

[0037] Construction process of the air supply shaft 3: 1. Clean the dust and debris on the surface of the base before construction; 2. Use cement mortar to level and slope; 3. Apply a waterproof layer; 4. Install and fix the metal cover 6 at the junction of the flap and the building's exterior wall 4; 5. Use φ8 stainless steel plastic expansion bolts to reliably connect the flap and the exterior wall; 6. Fill the space between the metal cover 6 and the surrounding structural layers with waterproof mortar.

[0038] In summary, the technical solution of this application has the following beneficial effects:

[0039] The utility model arranges rainproof louvers near the air shaft opening to effectively block rainwater; and a top cover with a leveling and sloping layer is provided above the air shaft opening, so that rainwater will not gather on the top cover when falling from above; at the same time, since the length of the top cover is longer than the air shaft outlet, rainwater will drip from the front end of the air shaft opening and will not affect the air shaft opening; waterproof materials are used to simplify the construction process, reducing manpower and time costs; the metal plate is firmly fixed to the exterior wall and the flap, and no gap is left between the metal plate and the slope and leveling layer, preventing rainwater from seeping in through the gap.
