Description

Technical Field

[0001] This utility model relates to the field of building structure engineering technology, and in particular to a waterproof joint for a dormer window. Background Technology

[0002] The exterior finish of a conventional dormer window is directly fixed to the window's own posts, which are then fixed to the roof purlins.

[0003] With exposure to sun and rain, the exterior finish and waterproofing materials of dormer windows age rapidly, making it easy for rainwater to seep in and run along the posts to the horizontal roof purlins, or even drip down, at which point the entire roof waterproofing system essentially fails. In addition to the aforementioned water leakage risks, it can also lead to severe corrosion of the dormer window posts and roof purlins. Utility Model Content

[0004] The purpose of this utility model is to provide a waterproof joint for dormer windows, so as to improve the waterproofing capability of the dormer window waterproof joint and reduce the safety risks caused by water leakage.

[0005] To solve the above-mentioned technical problems, this utility model provides a waterproof node for dormer windows.

[0006] The waterproof joint of the dormer window of this utility model includes:

[0007] Roof;

[0008] The interior columns of the window are fixedly connected to the roof at their base.

[0009] The external pillar is located on the outside of the internal pillar of the window;

[0010] A first waterproof support layer is fixedly laid on the outer surface of the roof. A first waterproof layer is fixedly laid on the outer surface of the first waterproof support layer. There is a gap between the bottom of the window cantilever column and the first waterproof support layer for the first waterproof layer to pass through.

[0011] The second waterproof support layer is fixed to the outer surface of the window cantilever column, and the surface of the second waterproof support layer is covered with a second waterproof layer.

[0012] Furthermore, the inner pillar and the outer pillar are fixedly connected.

[0013] Furthermore, the inner pillar and the outer pillar are fixedly connected by a horizontal support member.

[0014] Furthermore, the bottom surface of the second waterproof support layer is bonded to the top surface of the first waterproof layer.

[0015] Furthermore, an isolation cavity is formed between the inner pillar and the outer pillar, and a water-blocking block is provided in the isolation cavity, the water-blocking block being fixed to the upper surface of the first waterproof support layer.

[0016] Furthermore, the first waterproof layer covers the outer surface of the water-blocking embankment.

[0017] Furthermore, one side of the water-blocking embankment is fitted with the inner column of the window.

[0018] Furthermore, the water-blocking embankment block is a trapezoidal wooden block.

[0019] Furthermore, a water-draining slope is provided at the junction of the second waterproof support layer and the first waterproof layer.

[0020] Furthermore, the first waterproof support layer and / or the second waterproof support layer are wooden planks.

[0021] Compared with the prior art, the present invention has at least the following beneficial effects:

[0022] By employing a separate internal and external column structure and a layered waterproofing system, the problem of roof waterproofing system failure due to rainwater leakage at traditional dormer window waterproofing joints is effectively solved. The internal columns and external cantilever columns form a double-layer structure. The internal columns support and stabilize the dormer window, while the external cantilever columns serve to install the waterproofing layer and decorative surface of the dormer window's sidewalls. The external cantilever columns, located on the outer side, prevent rainwater from directly contacting the internal columns. A gap exists between the bottom of the external cantilever columns and the first waterproofing support layer, allowing the first waterproofing layer to extend inwards and ensuring continuous application. This prevents further intrusion of rainwater that may be present on the external cantilever columns. Therefore, the continuous application of the first waterproofing layer at the gap blocks the path of rainwater seepage along the external cantilever columns, while the second waterproofing layer forms a waterproof barrier on the outer facade.

[0023] The first waterproof support layer and the first waterproof layer constitute the waterproofing system for the outer surface of the roof, while the second waterproof support layer and the second waterproof layer form a waterproof barrier for the outer facade. The roof waterproofing layer and the facade waterproofing layer are interconnected, forming a three-dimensional waterproofing network. Through the layered design and gap fit of the double-layer waterproofing system, rainwater penetration paths are blocked, preventing rainwater from intruding into the roof structure and significantly improving the reliability and durability of the waterproofing system. Compared with existing technologies, this avoids direct contact between rainwater and the main load-bearing structure, reducing the risk of leakage and extending the service life of the waterproofing system.

[0032] The present invention will be described more specifically by way of example in the following paragraphs with reference to the accompanying drawings.

It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0033] The following is in conjunction with the instruction manual appendix. Figure 1 This paper introduces the waterproof joint of the dormer window of this utility model.

[0034] This utility model proposes a waterproof joint for dormer windows, such as... Figure 1 As shown, it includes a roof 1, window inner pillars 2, window outer hanging pillars 3, a first waterproof support layer 4, and a second waterproof support layer 5.

[0035] The bottom of the inner window pillar 2 is fixedly connected to the roof 1. The outer window hanging pillar 3 is located on the outside of the inner window pillar 2. The first waterproof support layer 4 is fixedly laid on the outer surface of the roof 1. The outer surface of the first waterproof support layer 4 is fixedly laid with a first waterproof layer 6. There is a gap between the bottom of the outer window hanging pillar 3 and the first waterproof support layer 4 for the first waterproof layer 6 to pass through. The second waterproof support layer 5 is fixed on the outer surface of the outer window hanging pillar 3. The surface of the second waterproof support layer 5 is laid with a second waterproof layer 7.

[0036] Specifically, the first waterproof support layer 4 can be made of wooden plywood or other waterproof boards, and its thickness can be adjusted according to actual needs. The first waterproof layer 6 can be made of waterproof membrane or waterproof coating, laid by adhesive or mechanical fixing. The gap width is usually 5-20mm to ensure that the first waterproof layer 6 can pass smoothly and maintain continuity. The second waterproof support layer 5 can also be made of wooden plywood, and its installation angle can be adjusted according to the building facade design. The second waterproof layer 7 can be made of the same or different waterproof materials as the first waterproof layer 6, and fixed by nailing or adhesive.

[0037] By setting up a separate internal and external column structure and a layered waterproofing system, the problem of roof waterproofing system failure due to rainwater leakage at traditional dormer window waterproofing joints is effectively solved. The internal column 2 and external cantilever column 3 form a double-layer structure. The internal column 2 supports and stabilizes the dormer window, while the external cantilever column 3 installs the waterproofing layer and decorative surface 8 on the dormer window sidewalls. The external cantilever column 3, located on the outside, prevents rainwater from directly contacting the internal column 2. A gap exists between the bottom of the external cantilever column 3 and the first waterproofing support layer 4, allowing the first waterproofing layer 6 to extend inwards, ensuring continuous installation and blocking further intrusion of rainwater that may be present on the external cantilever column 3. Therefore, the continuous installation of the first waterproofing layer 6 at the gap blocks the path of rainwater seepage along the external cantilever column 3, while the second waterproofing layer 7 forms a waterproof barrier on the outer facade.

[0038] The first waterproof support layer 4 and the first waterproof layer 6 constitute the waterproofing system for the outer surface of the roof 1, while the second waterproof support layer 5 and the second waterproof layer 7 form a waterproof barrier on the outer facade. The roof 1 waterproofing layer and the facade waterproofing layer are interconnected, forming a three-dimensional waterproofing network. Through the layered design and gap fit of the double-layer waterproofing system, the path of rainwater penetration is blocked, preventing rainwater from intruding into the roof 1 structure, significantly improving the reliability and durability of the waterproofing system. Compared with existing technologies, this avoids direct contact between rainwater and the main load-bearing structure, reducing the risk of leakage and extending the service life of the waterproofing system.

[0039] Furthermore, in some embodiments, the inner window pillar 2 and the outer window cantilever pillar 3 are fixedly connected.

[0040] Specifically, fixed connections can be achieved through mechanical connection methods such as welding, bolting, or riveting. Welding can achieve permanent rigid fixation, bolting facilitates later maintenance and adjustment, and riveting is suitable for connecting components of different materials.

[0041] As a preferred embodiment, a horizontal support member 9 can be installed between the inner window column 2 and the outer window cantilever column 3. This support member can be made of angle steel, channel steel, or I-beams, and is fixed to the inner window column 2 and the outer window cantilever column 3 by welding or bolting at both ends to form a stable support structure. Specifically, the horizontal support member 9 can be configured as a cross-shaped or X-shaped structure to enhance the torsional resistance of the connection node. Alternatively, it can be configured as a straight line to reduce structural complexity. Specifically, the installation position of the horizontal support member 9 is preferably at 1 / 3 to 2 / 3 of the column height; this arrangement effectively disperses the bending moment generated by wind loads. The cross-sectional dimensions of the horizontal support member 9 should be determined based on the column spacing and the expected load.

[0042] By rigidly connecting the inner window column 2 and the outer window cantilever column 3 to form an integrated load-bearing system, the relative displacement between the two can be effectively eliminated. The inner window column 2, as the main load-bearing component, transfers the load to the roof structure 1, while the outer window cantilever column 3 undertakes the installation and fixing functions of the waterproof structure and decorative surface 8. When subjected to wind loads or temperature deformation, the fixed connection ensures coordinated deformation of the two components, avoiding tearing of the waterproof layer due to displacement differences, significantly improving the joint stiffness and stability, and providing a continuous and reliable support foundation for the waterproof layer.

[0043] Furthermore, in some embodiments, the bottom surface of the second waterproof support layer 5 is attached to the upper surface of the first waterproof layer 6.

[0044] Specifically, the second waterproof support layer 5 can be made of metal plate, engineering plastic plate, or anti-corrosion treated wood board, and its bottom surface is mechanically fixed or adhesively bonded to the first waterproof layer 6 to achieve a seamless fit. In a preferred embodiment, the bottom surface of the second waterproof support layer 5 can be processed into a flat surface or have a slightly raised structure. A pre-compression process ensures uniform pressure distribution on the contact surface with the first waterproof layer 6, preventing damage to the first waterproof layer 6. The first waterproof layer 6 is preferably made of polymer waterproof membrane, and its surface can be roughened to enhance the interfacial friction coefficient.

[0045] A continuous sealed interface is formed through direct physical contact between two layers of waterproof material. The second waterproof support layer 5 serves as a rigid support, while the first waterproof layer 6 serves as a flexible seal. The combination of the two ensures both structural stability and interface sealing.

[0046] In addition, the upper surface of the second waterproof layer 7 is also covered with a waterproof membrane flange 10 to protect the second waterproof layer 7.

[0047] Furthermore, in some embodiments, an isolation cavity is formed between the inner window pillar 2 and the outer window cantilever pillar 3, and a water-blocking block 10 is provided in the isolation cavity, the water-blocking block 10 being fixed to the upper surface of the first waterproof support layer 4.

[0048] The isolation cavity refers to the gap space reserved between the inner window pillar 2 and the outer window cantilever pillar 3, and its width can be adjusted according to actual waterproofing requirements. The water-blocking block 10 can be made of waterproof materials such as trapezoidal wooden blocks, rubber blocks, or foamed polyethylene, among which the trapezoidal cross-section design is conducive to guiding rainwater outward. The water-blocking block 10 is fixed to the upper surface of the first waterproof support layer 4 by waterproof adhesive or mechanical fasteners, and its height must exceed the bottom of the cavity by at least 20mm to ensure effective water blocking. As a preferred embodiment, a sealing strip can be installed on the side of the water-blocking block 10 near the inner window pillar 2 to enhance the fit and sealing with the pillar.

[0049] Among them, trapezoidal wooden blocks refer to solid wood components with a trapezoidal cross-section, and the preferred slope angle is 45°-60°. In specific implementation, woods with natural preservative properties, such as fir and pine, can be used and shaped after preservative treatment. When the long side of the trapezoid contacts the inner window column 2, an elastic sealing strip can be installed on the contact surface, and the contact surface between the short side and the waterproof layer can be processed into an arc transition. The surface can be coated with a waterproof coating to enhance durability.

[0050] By forming a physical barrier inside the cavity through the water-blocking block 10, rainwater is forced to flow downward along the outer surface of the water-blocking block 10, preventing it from seeping down along the inner column 2 of the window. This not only extends the rainwater infiltration path, but also improves the local waterproof performance through the water-repellent properties of the material itself.

[0051] Preferably, in some embodiments, the first waterproof layer 6 covers the outer surface of the water-blocking block 10. Specifically, the outer surface of the water-blocking block 10 can be covered by: tightly wrapping the modified bitumen waterproof membrane onto the surface of the water-blocking block 10 using a hot-melt method; or applying multiple coats of polyurethane waterproof coating to form a continuous film layer; or using pre-formed rubber waterproof kits for fitting and fixing.

[0052] By completely enclosing the water-blocking embankment 10 with the first waterproof layer 6, a continuous waterproof barrier is formed, blocking the path of rainwater seepage along the interface between the water-blocking embankment 10 and the waterproof layer. This completely isolates rainwater from the outside of the waterproof system, effectively protecting the isolation cavity and internal structure from erosion. In specific implementation, the upper edge of the waterproof layer needs to extend to the inside of the window cantilever column 3 and be fixed.

[0053] Preferably, in some embodiments, one side of the water-blocking block 10 is abutted against the inner window pillar 2. The contact surface between the water-blocking block 10 and the pillar can be processed into a flat surface or a structure with a sealing groove. As a preferred embodiment, the water-blocking block 10 is fixed to the side of the pillar by structural adhesive or mechanical snap-fit ​​to ensure airtightness. The tight fit between the water-blocking block 10 and the inner window pillar 2 forms a continuous physical water-blocking barrier in the isolation cavity. This effectively eliminates the assembly gaps between components in traditional structures, preventing rainwater from seeping into the room through capillary action.

[0054] Furthermore, in some embodiments, a water-draining slope 11 is provided at the junction of the second waterproof support layer 5 and the first waterproof layer 6.

[0055] The water diversion slope 11 can be formed by concrete casting, with its inclination angle controlled within the range of 15-50 degrees. The surface needs to be smoothed to ensure smooth drainage. As an alternative implementation, the slope can also be formed by bending metal sheets, and the joints of the sheets need to be waterproofed and sealed. Anti-slip textures or drainage channels can be added to the slope surface to enhance drainage efficiency. The joint between the slope and the waterproof layer should be filled with elastic sealant and covered with reinforced waterproof membrane as an additional protective layer.

[0056] A sloping structure is set at the junction of the waterproof layers. The gravity gradient generated by the slope causes the accumulated rainwater to flow in a directional manner, effectively eliminating the phenomenon of water accumulation at the junction and shortening the rainwater retention time. This significantly reduces the performance degradation of the waterproof material caused by long-term immersion, extends the service life of the waterproof material, and reduces the frequency of maintenance.

[0057] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
