Description

Technical Field

[0001] The utility model relates to a positive angle closing structure of a building horizontal cantilever plate. Background Art

[0002] In addition to dry-hanging finishes, the outer sides of horizontal cantilevers such as building balconies generally use wet-work structures such as exterior wall tiles or exterior wall paints. The horizontal panels at this location are generally covered with latex paint and other ceiling methods. When the vertical wall and the horizontal ceiling surface meet at the corner, elastic sealants are often used to separate and seal the ends. This method also has many shortcomings: First, because sealants are used to seal the corners, a large amount of rainwater is sucked into the gaps after shrinkage, causing the base layer of the exterior wall tiles to expand and fall off; secondly, the ends of the tiles are suspended, and when the base layer is not fully adhered or hollows appear, the adhesive layer material shrinks with the temperature, which can easily cause it to fall off; horizontal cantilevers such as building balconies are the hot and cold bridges of the building, and are significantly affected by the ambient temperature. Cracks are easily formed at the corners where the two materials meet, affecting the overall appearance of the building. Utility Model Content

[0003] The purpose of the utility model is to overcome the above-mentioned deficiencies in the prior art and to provide a rationally designed building horizontal cantilever plate external corner closing structure to prevent the outer decorative layer from falling off while having both aesthetics and anti-deformation effects.

[0004] The technical solution adopted by the utility model to solve the above-mentioned problems is: a construction horizontal cantilever plate external corner closing structure, the horizontal cantilever plate is coated with a ceiling latex paint layer at the bottom, and an external decorative layer is fixed to the outer side surface; it is characterized in that: it also includes an aluminum alloy closing component, the aluminum alloy closing component is arranged at the external corner where the ceiling latex paint layer and the external decorative layer meet; the aluminum alloy closing component includes a reinforcing rib, a cantilever plate and a fixed plate; the fixed plate is arranged at the bottom of the horizontal cantilever plate, and the fixed plate is fixed to the horizontal cantilever plate by expansion bolts; the cantilever plate extends out of the outer side surface of the horizontal cantilever plate, one end of which is connected and fixed to the fixed plate, and the other end is connected to the external decorative layer; a reinforcing rib is fixed at the junction of the cantilever plate and the fixed plate, and a reinforcing rib is also fixed inside the cantilever plate; elastic sealant is filled between the aluminum alloy closing component and the ceiling latex paint layer, and elastic sealant is also filled between the aluminum alloy closing component and the external decorative layer.

[0005] The exterior decorative layer of the utility model is exterior wall tiles or exterior wall paint.

[0006] The fixing plate of the utility model is provided with bolt holes in advance, and the expansion bolts are arranged in the bolt holes.

[0007] One end of the cantilevered plate of the utility model is rotated inwardly to form a rotating reinforcement structure, and the rotating reinforcement structure is connected with the outer decorative layer.

[0008] The cantilevered plate of the utility model is U-shaped.

[0009] The utility model is provided with a drip groove at the bottom of the cantilevered plate.

[0010] Compared with the prior art, the utility model has the following advantages and effects:

[0011] First of all, it has good waterproof sealing properties, which can achieve the closing treatment of the positive corners of the horizontal cantilever slabs of the building to prevent rainwater from gathering and penetrating and destroying the bonding layer.

[0012] Secondly, the aluminum alloy closing component adopts a cavity structure, with reinforcing ribs set at certain intervals to give it a certain rigidity. It is connected to the horizontal cantilever plate through bolts, which can well withstand the vertical force of the local exterior wall finish and prevent the exterior wall material from cracking and falling off.

[0013] Finally, the aluminum alloy closing components are made of aluminum alloy, and elastic sealants can be used to close the exterior wall finishes and ceiling surface layers. The structural layers are clear and the material texture is good. The strong adaptability of aluminum alloy metal materials to environmental temperature deformation is utilized, while the sealing characteristics of traditional elastic sealants are brought into play. The combination of the two is both rigid and flexible and the force is evenly distributed, so that the structure can very well connect the two materials of the exterior wall and the ceiling, and adapt to their different deformation amounts, so as to better achieve sealing and waterproofing of the positive corners.
