Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to waterproof structures for building engineering. Background Technology

[0002] With the development of building engineering technology, building waterproofing technology has emerged, mainly including two methods: structural waterproofing and material waterproofing. Structural waterproofing primarily involves optimizing the design of the building structure to guide water flow away from the protected parts of the building. Material waterproofing utilizes various waterproof materials to form a waterproof layer on the building surface. However, after long-term use, waterproofing materials will age and become damaged under the influence of ultraviolet rays, temperature, and external forces, thus failing to effectively perform their waterproofing function.

[0003] In related technologies, for example, patent number CN216892880U discloses a waterproof structure for building engineering, which is a planar waterproof membrane structure. Typically, after simple cleaning of the base layer of the roof or wall of a building, the waterproof membrane is directly laid in a certain order.

[0004] However, in actual construction projects, roof shapes are complex and diverse, including flat roofs, pitched roofs, and various irregular roofs. The aforementioned waterproofing structures cannot flexibly adjust their angles according to different roof shapes during installation. If splicing is used to adapt to different roof shapes, the splicing seams are prone to aging and water ingress after long-term use, which greatly reduces the waterproofing effect, increases the risk of building leakage, and seriously affects the overall waterproofing performance and durability of the building. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a waterproof structure for building engineering that can flexibly adjust the angle to closely fit the roof structure and enhance the waterproof performance.

[0006] The objective of this utility model is achieved through the following technical solution:

[0007] The waterproofing structure for building construction includes a first waterproofing membrane, which is a U-shaped membrane with its opening facing upwards; a plurality of the first waterproofing membranes are evenly spaced along the horizontal direction.

[0008] The second waterproofing membrane is a U-shaped membrane with its opening facing downwards. The second waterproofing membrane is disposed between two adjacent first waterproofing membranes. One horizontal side of the second waterproofing membrane is pivotally connected to one of the adjacent first waterproofing membranes, and the other horizontal side of the second waterproofing membrane is pivotally connected to another adjacent first waterproofing membrane. The second side baffle of the second waterproofing membrane overlaps with the projection of the groove of the first waterproofing membrane on the horizontal plane. The second side baffle of the second waterproofing membrane is used to introduce rainwater into the groove of the first waterproofing membrane.

[0009] Preferably, the main body of the second waterproof membrane covers the gap between two adjacent first waterproof membranes, and the second side baffle of the second waterproof membrane is set at an angle A with the main body of the second waterproof membrane, wherein 90° < A < 180°.

[0010] Preferably, a waterproof membrane is connected between two adjacent first waterproof membranes, and the waterproof membrane extends along the length of the first waterproof membrane.

[0011] Preferably, the inner bottom surface of the groove of the first waterproof membrane has a downward slope towards the horizontal opening ends located on opposite sides.

[0012] Preferably, the waterproof structure of the building project further includes a baffle device, which is disposed on the first waterproof board at both ends; the baffle device includes a baffle and a support rod; the baffle is hinged to a first side baffle of the first waterproof board; a rectangular groove is formed on the outer wall of the first side baffle of the first waterproof board, which is used to accommodate the baffle; the baffle has a receiving groove, which is used to accommodate the support rod; one end of the support rod is located in the receiving groove and is pivotally connected to the baffle; the other end of the support rod can abut against the bottom wall of the rectangular groove.

[0013] Preferably, the waterproof structure of the building project further includes a drainage device; the drainage device includes two water diversion channels; the two water diversion channels are respectively disposed below the horizontal opening ends on opposite sides of the first waterproof board; the water diversion channels extend along the arrangement direction of the plurality of first waterproof boards and are used to collect water falling from the plurality of first waterproof boards.

[0014] Preferably, the diversion device further includes an adjustment device corresponding to the water diversion trough; the adjustment device includes at least two vertically arranged telescopic rods; the two telescopic rods are respectively disposed at both ends of the water diversion trough; the telescopic rod includes a fixed part and a movable part, the fixed part and the movable part are telescopically connected; the end of the fixed part away from the movable part is connected to the bottom of the first waterproof plate, and the end of the movable part away from the fixed part is spherically hinged to the side wall of the water diversion trough.

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

[0016] 1. The first waterproofing membrane, as a basic supporting component, has a U-shaped design that effectively collects and guides rainwater towards the predetermined drainage direction, reducing the risk of rainwater accumulation on building surfaces. The opening of the first waterproofing membrane faces upwards, facilitating rainwater reception and drainage, while also forming a good drainage channel structure to improve drainage efficiency. Multiple first waterproofing membranes are evenly spaced horizontally to form the basic waterproofing component.

[0017] 2. The second waterproofing membrane, as a covering component, features a downward-facing U-shaped opening that protects the gaps in the first waterproofing membrane, preventing rainwater from directly bypassing it and reducing the risk of leakage. The second waterproofing membrane connects flexibly to the adjacent first waterproofing membrane via a pivot joint, allowing it to adapt to roof shapes while minimizing seams and reducing the risk of leakage due to aging gaps. The second side baffle is designed to guide rainwater directly into the grooves of the first waterproofing membrane, ensuring controlled water flow.

[0018] 3. The double U-shaped structure of the first and second waterproof membranes works together to form a multi-layered protection and precise drainage system, significantly improving waterproof performance and preventing rainwater leakage and diffusion. The evenly spaced first waterproof membrane and the covering second waterproof membrane complement each other, forming a robust and durable waterproof structure capable of resisting external forces and long-term UV radiation. The modular design and pivot connection method simplify the installation process, reducing construction difficulty and labor costs. Attached Figure Description

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the specification of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0028] See Figures 1-5 This invention illustrates a preferred embodiment of a waterproofing structure for building engineering, comprising: a first waterproofing plate 1 and a second waterproofing plate 2.

[0029] The first waterproof membrane 1 and the second waterproof membrane 2 are U-shaped panels made of waterproof roll material, which are wrapped with a sound insulation layer, a waterproof layer and a surface material layer in sequence. The material has good UV resistance and high temperature resistance, and can effectively resist the harsh outdoor environment of the building waterproof structure for a long time.

[0030] The first waterproofing membrane 1 is a U-shaped membrane with its opening facing upwards, and multiple first waterproofing membranes 1 are evenly spaced along the horizontal direction. The first waterproofing membrane 1 helps to collect and guide rainwater while enhancing structural strength.

[0031] The second waterproofing membrane 2 is a U-shaped plate with its opening facing downwards. It is positioned between two adjacent first waterproofing membranes 1, cooperating with them to guide rainwater into the grooves of the first waterproofing membranes 1. One horizontal side of the second waterproofing membrane 2 is pivotally connected to one of the adjacent first waterproofing membranes 1, and the other horizontal side is pivotally connected to the other adjacent first waterproofing membrane 1. Schematic, the second waterproofing membrane 2 is positioned between two adjacent first waterproofing membranes 1, with one side pivotally connected to one of the adjacent first waterproofing membranes 1 via a flexible and high-strength rubber hinge, and the other side pivotally connected to the other adjacent first waterproofing membrane 1 via the same rubber hinge. The rubber hinge allows the second waterproofing membrane 2 to rotate freely while providing good sealing, adapting to angle changes caused by different roof shapes.

[0032] The projection of the second side baffle 21 of the second waterproof membrane 2 onto the groove of the first waterproof membrane 1 on the horizontal plane overlaps. The second side baffle 21 of the second waterproof membrane 2 is used to introduce rainwater into the groove of the first waterproof membrane 1, ensuring that rainwater can be accurately introduced from the second waterproof membrane 2 into the groove of the first waterproof membrane 1.

[0033] As an illustration, stainless steel anchors can be used to fix the first waterproofing membrane 1 to the roof base layer to prevent the waterproofing structure of the building from shifting under the action of external forces such as wind. At the point where the anchors pass through the waterproofing membrane and are fixed to the base layer, butyl rubber sealing gaskets are installed, with an inner diameter matching the diameter of the anchors, to effectively prevent rainwater from seeping in through the anchor holes and enhance the waterproofing effect.

[0034] As an illustration, when installing waterproofing structures in building construction, the first waterproofing board 1 and the second waterproofing board 2 can be customized according to the specific shape of the irregular roof. Then, the first waterproofing board 1 is glued to the base layer of the irregular roof with sealant. Next, the angle of the second waterproofing board 2 is adjusted using a pivot shaft, and the next first waterproofing board 1 is fixedly installed. This process is repeated sequentially.

[0035] As an illustration, when installing a waterproof structure in a building project, the first waterproof membrane 1 can be fixed to the base layer of the pitched roof at the designed spacing using anchor nails and sealing washers. Then, the second waterproof membrane 2 can be pivotally connected to the adjacent first waterproof membrane 1 using flexible rubber hinges.

[0036] In this embodiment, preferably, refer to Figures 1-4 The main body of the second waterproof membrane 2 covers the gap between two adjacent first waterproof membranes 1. The second side baffle 21 of the second waterproof membrane 2 is set at an angle A with the main body of the second waterproof membrane 2, where 90° < A < 180°. The inclined second side baffle 21 helps to guide rainwater to the groove of the first waterproof membrane 1 more effectively, while increasing the residence time of rainwater on the second waterproof membrane 2 and reducing the possibility of rainwater leaking directly from the gap.

[0037] In this embodiment, preferably, refer to Figures 1-4 A waterproof membrane 3 connects two adjacent first waterproof membrane boards 1. The waterproof membrane 3 extends along the length of the first waterproof membrane board 1 and fits tightly against the edge of the first waterproof membrane board 1, further sealing the gap between the adjacent first waterproof membrane boards 1 and preventing rainwater from seeping through the gap. The waterproof membrane 3 is a flexible waterproof membrane to accommodate different displacements of the first waterproof membrane board 1 and the second waterproof membrane board 2 according to different roofs.

[0038] In this embodiment, preferably, the inner bottom surface of the groove of the first waterproof membrane 1 has a downward slope towards the horizontal opening ends located on opposite sides, so that the collected rainwater flows quickly to the horizontal opening ends on opposite sides of the first waterproof membrane 1, avoiding the accumulation of rainwater in the groove of the first waterproof membrane 1, and reducing the pressure and erosion risk to the waterproof membrane caused by long-term water accumulation.

[0039] In this embodiment, preferably, refer to Figure 5 The waterproofing structure of the building project also includes a baffle device 4, which is installed on the first waterproofing plate 1 at both ends, and plays a role in protecting and guiding the edges of the waterproofing structure. The baffle device 4 includes a baffle 41 and a support rod 42. The baffle 41 is hinged to the first side baffle 11 of the first waterproofing plate 1. The outer wall of the first side baffle 11 of the first waterproofing plate 1 has a rectangular groove 111 for accommodating the baffle 41. When the baffle 41 is not in use, it can be stored in it without affecting the appearance and other functions of the overall waterproofing structure. The baffle 41 has a receiving groove 411 for accommodating the support rod 42. One end of the support rod 42 is located in the receiving groove 411 and is pivotally connected to the baffle 41. The other end of the support rod 42 can abut against the bottom wall of the rectangular groove 111. When the baffle 41 is needed, the support rod 42 can be rotated out of the receiving groove 411 so that one end of it is supported on the bottom wall of the rectangular groove 111, thereby supporting the baffle 41, changing the direction of rainwater flow or preventing debris from entering the waterproof structure.

[0040] In this embodiment, preferably, refer to Figure 1 , Figure 2 and Figure 4 The waterproof structure of the building project also includes a diversion device 5 to guide water flow into a designated sewer or connect to the building's own sewage system. The diversion device 5 includes two water diversion channels, which are respectively located below the horizontal opening ends on opposite sides of the first waterproofing plate 1. The water diversion channels extend along the arrangement direction of the multiple first waterproofing plates 1, and the length is determined according to the arrangement length of the first waterproofing plates 1. The water diversion channels are used to receive water falling from the multiple first waterproofing plates 1.

[0041] In this embodiment, preferably, refer to Figure 4The drainage device 5 also includes an adjustment device corresponding to the water diversion channel. The adjustment device includes at least two vertically arranged telescopic rods 52, each located at one end of the water diversion channel. Each telescopic rod 52 includes a fixed part and a movable part, which are telescopically connected. The end of the fixed part away from the movable part is connected to the bottom of the first waterproof membrane 1, and the end of the movable part away from the fixed part is spherically hinged to the side wall of the water diversion channel. Through the telescopic movement of the telescopic rods 52 and the spherical hinge structure, the height and angle of the water diversion channel can be flexibly adjusted according to the actual roof conditions. When the first waterproof membrane 1, with its two connecting telescopic rods 52 at different heights, the angles of the two telescopic rods 52 and the spherical hinge can be adjusted to ensure the water diversion channel is in a horizontal position, thus ensuring that the water diversion channel can better receive rainwater flowing down from the first waterproof membrane 1 and improve drainage efficiency.
