Description

Technical Field

[0001] The invention belongs to the technical field of building decoration and renovation, and particularly relates to the structure and construction method of a drip eave at a positive corner of a building. Background Art

[0002] For the convenience of construction, the external corners of buildings are usually trimmed into right angles. For better waterproofing, waterproof materials are laid on the wall, and the laid waterproof materials cover the external corners. The patent with publication number CN208430641U provides a building waterproof material external corner structure. This patent has the advantages that the waterproof material is not easy to crack at the external corners of the building wall and has a good waterproof effect; the side of the circular arc structure of the liner has an extended inclined surface, and the inclined surface is tangent to the circular arc structure, which also has the advantage of better bonding between the waterproof material layer and the outside of the liner; the liner is made of polyurethane material, and also has the advantages of aging resistance and elasticity at the external corners. The liner has a hollow structure inside and has the advantage of low cost.

[0003] The above-mentioned building waterproof material positive corner structure adopts a raised arc-shaped structure and a pad set on the outside of the waterproof material layer at the positive corner of the building. Since the protrusion is set at the top edge of the building, the accumulated water on the top of the building cannot be discharged, and the accumulated water accumulates on the upper end of the waterproof material for a long time, thereby shortening the service life of the waterproof material and the positive corner structure.

[0004] The rainwater on the top of the building gathers at the horizontal plane of the sunny corner and flows down the facade. After a long period of scouring, serious stains will be left on the facade, affecting the beauty of the building. Summary of the Invention

[0005] In order to solve the above problems existing in the prior art, the purpose of the present invention is to provide a structure and construction method for the drip eaves at the positive corners of a building to avoid water stains flowing down the facade of the building and water accumulation on the top of the building.

[0006] The technical solution adopted in the present invention is: The structure of a drip eave at a building's external corner includes a drip eave arranged at the building's external corner; the drip eave includes a cornice board, which is arranged horizontally, and is connected to a plurality of vertical boards and a plurality of horizontal boards, wherein the plurality of horizontal boards are respectively connected to the horizontal surface of the building's external corner by self-tapping screws, and the plurality of vertical boards are respectively connected to the vertical surface of the building's external corner by self-tapping screws; when a decorative layer is provided on the building surface, the upper surface of the cornice board is flush with the decorative layer on the horizontal surface of the building's external corner, and the outer end of the cornice board extends out of the vertical surface of the building's external corner; when no decorative layer is provided on the building surface, the upper surface of the cornice board is flush with the horizontal surface of the building's external corner, and the outer end of the cornice board extends out of the decorative layer on the vertical surface of the building's external corner.

[0007] The vertical and horizontal panels of the drip eaves of the present invention can be securely connected to the vertical and horizontal surfaces of a building's exterior corner, thereby ensuring the stable position of the eaves. When a decorative layer is applied to the building's surface, the upper surface of the eaves is flush with the decorative layer on the horizontal surface of the building's exterior corner; when no decorative layer is applied to the building's surface, the upper surface of the eaves is flush with the horizontal surface of the building's exterior corner. As a result, water on the horizontal surface of the exterior corner or on the decorative layer on the horizontal surface can flow smoothly onto the eaves, preventing water from accumulating horizontally on the exterior corner.

[0008] Furthermore, when a decorative layer is applied to the building's surface, the outer end of the cornice board extends beyond the vertical surface of the building's exterior corner. When no decorative layer is applied to the building's surface, the outer end of the cornice board extends beyond the decorative layer on the vertical surface of the building's exterior corner. This prevents water from flowing onto the exterior corner's facade or the decorative layer on the facade, preventing serious stains on the facade and ensuring the building's aesthetics.

[0009] As a preferred embodiment of the present invention, a decorative layer is provided on the building surface, with both vertical and horizontal panels embedded between the decorative layer and the building's exterior corner, and the cornice panels extend beyond the decorative layer. The top of the decorative layer on the vertical surface of the building's exterior corner abuts the cornice panels, and the upper surface of the cornice panels is flush with the decorative layer on the horizontal surface of the building's exterior corner. No other structures are provided on the cornice panel surface.

[0010] As a preferred embodiment of the present invention, the decorative layer is putty that is scraped onto the surface of the building.

[0011] As a preferred embodiment of the present invention, the vertical and horizontal panels on the drip eaves are each one piece. The eaves panel, vertical and horizontal panels are integrally formed. To allow space for a decorative layer, the eaves panel is taller than the horizontal panels.

[0012] As a preferred solution of the present invention, the material of the drip eaves is PVC material.

[0013] As a preferred solution of the present invention, no decorative layer is provided on the building surface, and the vertical panels and horizontal panels are respectively adhered to the vertical and horizontal surfaces of the building. There are at least two horizontal panels, and gaps are left between adjacent horizontal panels.

[0014] As a preferred embodiment of the present invention, the number of vertical panels is also at least two, and a plurality of horizontal panels are spaced apart from the vertical panels. The plurality of vertical panels and the plurality of horizontal panels are spaced apart on the eaves panel, so that rainwater on the horizontal surface of the building's exterior corners can flow through the gaps between adjacent horizontal panels to the eaves panel, thereby preventing water from accumulating on the building's roof.

[0015] As a preferred solution of the present invention, the drip eaves are made of stainless steel.

[0016] The construction method of the structure of the drip eaves at the positive corner of a building comprises the following steps: When installing a decorative layer on the surface of a building: fit the horizontal plate to the horizontal surface of the building's external corner and connect it with self-tapping screws, fit the vertical plate to the vertical surface of the building's external corner and connect it with self-tapping screws; install the decorative layer on the surface of the building until the upper surface of the horizontal plate is flush with the decorative layer on the horizontal surface of the building's external corner; When there is no decorative layer on the surface of the building: fit several horizontal boards to the horizontal surfaces of the building's outside corners and connect them respectively with self-tapping screws, fit several vertical boards to the vertical surfaces of the building's outside corners and connect them respectively with self-tapping screws; use glass glue to seal the connection between the drip eaves and the building.

[0017] As a preferred embodiment of the present invention, when a decorative layer is provided on the surface of a building, the drip eaves are integrally injection-molded; when no decorative layer is provided on the surface of the building, the drip eaves are formed by evenly cutting one side of a whole piece of stainless steel, staggeredly separating and bending several cut parts to form several horizontal plates and several vertical plates arranged at intervals, and the uncut side of the stainless steel is the cornice plate.

[0018] The beneficial effects of the present invention are: 1. The vertical and horizontal panels of the drip eaves of the present invention securely connect to the vertical and horizontal surfaces of a building's exterior corner, ensuring the stable position of the eaves. When a decorative layer is applied to the building's surface, the upper surface of the eaves is flush with the decorative layer on the horizontal surface of the building's exterior corner. When no decorative layer is applied to the building's surface, the upper surface of the eaves is flush with the horizontal surface of the building's exterior corner. This allows water on the horizontal surface of the building's exterior corner or on the decorative layer to flow smoothly onto the eaves, preventing horizontal accumulation of water in the building's exterior corner.

[0019] 2. When a building is decorated, the outer end of the cornice extends beyond the vertical surface of the building's exterior corner. When no decorative layer is applied, the outer end of the cornice extends beyond the decorative layer on the vertical surface of the building's exterior corner. This prevents water from flowing onto the exterior corner or the decorative layer, preventing serious stains on the facade and maintaining the building's aesthetics.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0023] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention. It should be noted that the embodiments of the present invention and the features therein may be combined with each other unless there is a conflict.

[0024] like Figures 1 to 6 As shown, the structure of the drip eaves of the building's external corner in this embodiment includes a drip eaves 2 arranged at the external corner of the building 1; the drip eaves 2 includes a cornice board 21, the cornice board 21 is horizontally arranged, and a plurality of vertical boards 22 and a plurality of horizontal boards 23 are connected to the cornice board 21, and the plurality of horizontal boards 23 are respectively connected to the horizontal surface of the external corner of the building 1 by self-tapping screws 3, and the plurality of vertical boards 22 are respectively connected to the vertical surface of the external corner of the building 1 by self-tapping screws 3; when a decorative layer 4 is provided on the surface of the building 1, the upper surface of the cornice board 21 is flush with the decorative layer 4 on the horizontal surface of the external corner of the building 1, and the outer end of the cornice board 21 extends out of the vertical surface of the external corner of the building 1; when no decorative layer 4 is provided on the surface of the building 1, the upper surface of the cornice board 21 is flush with the horizontal surface of the external corner of the building 1, and the outer end of the cornice board 21 extends out of the decorative layer 4 on the vertical surface of the external corner of the building 1.

[0025] The vertical panels 22 and horizontal panels 23 of the drip eave 2 of the present invention are securely connected to the vertical and horizontal surfaces of the exterior corner of the building 1, thereby ensuring the stable position of the cornice board 21. When the decorative layer 4 is installed on the surface of the building 1, the upper surface of the cornice board 21 is flush with the decorative layer 4 on the horizontal surface of the exterior corner of the building 1; when the decorative layer 4 is not installed on the surface of the building 1, the upper surface of the cornice board 21 is flush with the horizontal surface of the exterior corner of the building 1. As a result, water on the decorative layer 4 on the horizontal surface of the exterior corner of the building 1 can flow smoothly onto the cornice board 21, preventing water from accumulating on the horizontal surface of the exterior corner of the building 1.

[0026] Furthermore, when the decorative layer 4 is provided on the surface of the building 1, the outer end of the cornice board 21 extends beyond the vertical surface of the exterior corner of the building 1. When the decorative layer 4 is not provided on the surface of the building 1, the outer end of the cornice board 21 extends beyond the decorative layer 4 on the vertical surface of the exterior corner of the building 1. As a result, rainwater flows along the cornice board 21 to the ground, and water on the top surface of the building 1 does not flow onto the facade of the exterior corner of the building 1 or the decorative layer 4 on the facade, thus preventing serious stains on the facade and ensuring the aesthetics of the building 1.

[0027] The first solution of this embodiment: like Figure 1 and Figure 1 As shown, a decorative layer 4 is provided on the surface of building 1. Vertical panels 22 and horizontal panels 23 are embedded between the decorative layer 4 and the exterior corner of building 1. Cornice panels 21 extend beyond the decorative layer 4. The top of the decorative layer 4 on the vertical surface of the exterior corner of building 1 abuts against the cornice panels 21. The upper surface of cornice panels 21 is flush with the decorative layer 4 on the horizontal surface of the exterior corner of building 1. No other structures are provided on the surface of cornice panels 21.

[0028] The decorative layer 4 is a putty applied to the surface of the building 1. After the putty is applied to the surface of the building 1, the putty layer is flush with the cornice board 21 of the drip eaves 2, which can make the rain flow smoothly from the drip eaves 2 while ensuring the beauty of the building 1.

[0029] The vertical plate 22 and the horizontal plate 23 on the drip eaves 2 are each one piece. The cornice plate 21, the vertical plate 22 and the horizontal plate 23 are integrally formed. To leave space for the decorative layer 4, the cornice plate 21 is higher than the horizontal plate 23.

[0030] The material of the drip eaves 2 is PVC material, which has good adhesion to the putty layer. At the same time, the vertical plate 22 and the horizontal plate 23 of the drip eaves 2 are designed as porous bricks, which can further increase the adhesion between the drip eaves 2 and the putty layer and extend the service life.

[0031] The second solution of this embodiment: like Figures 3 to 6As shown, no decorative layer 4 (such as granite) is provided on the surface of the building 1 , and the vertical plates 22 and the horizontal plates 23 are respectively adhered to the vertical and horizontal surfaces of the building 1 . There are at least two horizontal plates 23 , and gaps are left between adjacent horizontal plates 23 .

[0032] There are also at least two vertical panels 22, and a plurality of horizontal panels 23 are spaced apart from the vertical panels 22. The vertical panels 22 and the horizontal panels 23 are spaced apart on the cornice panel 21, so that rainwater on the horizontal surface of the exterior corner of the building 1 can flow from the gaps between adjacent horizontal panels 23 to the cornice panel 21, thereby preventing water from accumulating on the roof of the building 1.

[0033] The drip eaves 2 are made of stainless steel, which can maintain structural stability and aesthetics in harsh environments. The cornice board 21 of the drip eaves 2 is slightly lower than the horizontal board 23. When installed, the cornice board 21 of the drip eaves 2 is flush with the horizontal surface of the exterior corner of the building 1, allowing rainwater to flow smoothly from the drip eaves 2 while preventing rainwater from pooling on the flat surface of the building 1.

[0034] The construction method of the structure of the drip eaves at the exterior corner of the building of the present embodiment comprises the following steps: When the decorative layer 4 is provided on the surface of the building 1: the horizontal plate 23 is aligned with the horizontal surface of the external corner of the building 1 and connected via self-tapping screws 3, and the vertical plate 22 is aligned with the vertical surface of the external corner of the building 1 and connected via self-tapping screws 3; the decorative layer 4 is provided on the surface of the building 1 until the upper surface of the horizontal plate 23 is flush with the decorative layer 4 on the horizontal surface of the external corner of the building 1; the drip eaves 2 are integrally injection molded; When the decorative layer 4 is not provided on the surface of the building 1: a number of horizontal plates 23 are attached to the horizontal surface of the outside corner of the building 1 and are connected respectively by self-tapping screws 3, and a number of vertical plates 22 are attached to the vertical surface of the outside corner of the building 1 and are connected respectively by self-tapping screws 3; the connection part between the drip eaves 2 and the building 1 is sealed with glass glue to prevent rainwater from flowing down from the gap; the drip eaves 2 is formed by evenly cutting one side of the whole piece of stainless steel, staggeredly separating and bending several cut parts to form a number of horizontal plates 23 and a number of vertical plates 22 arranged at intervals, and the uncut side of the stainless steel is the cornice plate 21.

[0035] The present invention is not limited to the above-mentioned optional implementation modes. Anyone can derive other forms of products under the inspiration of the present invention. However, no matter what changes are made in the shape or structure, any technical solution that falls within the scope defined by the claims of the present invention falls within the scope of protection of the present invention.
