Description

Technical Field

[0001] The utility model relates to the technical field of building engineering construction, in particular to a waterproof building curtain wall. Background Art

[0002] During the construction of building projects, it is necessary to install curtain walls on reinforced concrete window sills. Curtain walls are lightweight walls with decorative effects commonly used in modern large and high-rise buildings. They are composed of panels and supporting structural systems, and can have a certain displacement ability relative to the main structure or a certain deformation ability of the building itself, and are not subject to the effects of the main structure. The building's external protective structure or decorative structure (the external wall frame support system is also a type of curtain wall system) does not bear the effects of the main structure.

[0003] In the prior art, when installing curtain walls on reinforced concrete window sills, waterproof mortar or polyurethane foaming agent combined with sealant is used to fill the space between the reinforced concrete window sill and the curtain wall. However, after long-term use, due to shrinkage cracks in the waterproof mortar or aging and cracking of the sealant, rainwater will leak into the room through the gap between the concrete window sill and the curtain wall, resulting in poor waterproof performance.

[0025] In order to make the purpose, technical solution and advantages of the implementation mode of the present invention clearer, the technical solution in the implementation mode of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the implementation mode of the present invention.

[0026] Example:

[0027] Reference Figure 1-Figure 5A waterproof building curtain wall is applied to a reinforced concrete window sill 1 of a building structure. The building curtain wall includes a curtain wall main board 3 arranged on the reinforced concrete window sill 1. Two angle iron connectors 4 are arranged on the top of the curtain wall main board 3, and two angle iron connectors 4 are also arranged on the bottom of the curtain wall main board 3 to ensure the stability of the top and bottom of the curtain wall main board 3 when connected. The angle iron connector 4 is a galvanized steel plate, which has the advantages of good reliability, corrosion resistance and strong toughness. The angle iron connector 4 is an L-shaped structure, and the two sides of any of the angle iron connectors 4 are respectively fitted with the curtain wall main board 3 and the concrete window sill, and the angle iron connector 4 is connected to the reinforced concrete window sill 1 by nailing to achieve the rapid installation of the angle iron connector 4. A concrete layer is arranged between the bottom of the curtain wall main board 3 and the reinforced concrete window sill 1. A plaster layer 5 is arranged on the inner side of the connection between the bottom of the curtain wall main board 3 and the reinforced concrete window sill 1. The two ends of the plaster layer 5 are respectively connected to the two side edges of the reinforced concrete window sill 1. The top side of the plaster layer 5 is an inclined surface, and the horizontal plane of the plaster layer 5 close to one end of the curtain wall main board 3 is higher than the horizontal plane of the plaster layer 5 away from one end of the curtain wall main board 3. The design of the concrete layer and the plaster layer 5 between the bottom of the curtain wall main board 3 and the reinforced concrete window sill 1 can prevent external rainwater from penetrating from the gap at the bottom of the curtain wall main board 3, and the design of the plaster layer 5 with high outside and low inside can further improve the waterproof performance.

[0028] The outer wall of the reinforced concrete window sill 1 is provided with a waterproof board 2, which is located above the curtain wall main board 3. The waterproof board 2 is a concave board, and the two vertical parts of the concave board are both connected to the outer wall of the reinforced concrete window sill 1. The concave board is relatively large in size, which can ensure that the distance from the outer side of the waterproof board 2 to the outer wall of the concrete window sill is greater than the distance from the curtain wall main board 3 to the outer wall of the concrete window sill. At the same time, it can also reduce the weight of the waterproof board 2, which is practical. By installing the waterproof board 2 above the curtain wall main board 3, rainwater on the outer wall of the reinforced concrete window sill 1 is prevented from flowing to the top installation gap of the curtain wall main board 3, effectively reducing the possibility of leakage from the top of the curtain wall main board 3.

[0029] Preferably, the plaster layer 5 is made of polymer waterproof mortar, and the slope of the top side of the plaster layer 5 is not less than 1%.

[0030] In some embodiments of the present invention, a drip line 6 is provided on the bottom side of the waterproof board 2, and the distance from the drip line 6 to the concrete window sill outer wall is greater than the distance from the curtain wall main board 3 to the concrete window sill outer wall.

[0031] In the above embodiment, the drip line 6 is designed to prevent rainwater from flowing along the lower surface of the waterproof board 2 to the top of the curtain wall, effectively reducing the possibility of leakage on the upper part of the curtain wall. The width of the drip line 6 is not less than 10 mm.

[0032] In some embodiments of the utility model, a first connecting member 7 is provided on the outer side of the connection between the top of the curtain wall main board 3 and the reinforced concrete window sill 1, the top of the first connecting member 7 is simultaneously connected to the waterproof board 2 and the outer wall of the reinforced concrete window sill 1, and the bottom of the first connecting member 7 and the curtain wall main board 3 are connected by bolts.

[0033] In the above embodiment, the first connecting member 7 realizes the connection between the top of the curtain wall main board 3 and the reinforced concrete window sill 1, further improving the stability of the installation of the curtain wall main board 3. At the same time, the first connecting member 7 shields the connection between the curtain wall main board 3 and the reinforced concrete window sill 1, and the waterproof performance is further improved.

[0034] In some embodiments of the present invention, a second connecting member 8 is provided on the outer side of the connection between the bottom of the curtain wall main board 3 and the reinforced concrete window sill 1, the top of the second connecting member 8 and the curtain wall main board 3 are connected by bolts, and the bottom of the second connecting member 8 is connected to the outer wall of the reinforced concrete window sill 1.

[0035] In the above embodiment, the second connecting member 8 realizes the connection between the bottom of the curtain wall main board 3 and the reinforced concrete window sill 1, further improving the stability of the installation of the curtain wall main board 3. At the same time, the second connecting member 8 blocks the connection between the curtain wall main board 3 and the reinforced concrete window sill 1, and the waterproof performance is further improved.

[0036] In some embodiments of the present invention, the gap between the first connecting member 7 and the curtain wall main board 3 and the gap between the second connecting member 8 and the curtain wall main board 3 are both sealed with glue.

[0037] In the above embodiment, glue seals the gap between the first connecting member 7 and the above curtain wall main board 3, and the gap between the above second connecting member 8 and the above curtain wall main board 3, which not only improves the connection stability between the curtain wall main board 3 and the first connecting member 7 and the second connecting member 8, but also improves the waterproof function of the curtain wall main board 3.

[0038] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
