Description

Technical Field

[0001] This utility model relates to the field of steel structure roofing technology, and in particular to a parapet wall inner panel lower end installation structure. Background Technology

[0002] In modern architectural design, the parapet wall, as part of the building's external envelope, not only beautifies the building's appearance but also has a crucial impact on its overall waterproofing performance. Traditionally, the lower end of the parapet wall panel is installed using direct fixing. While simple and easy, this method presents several significant problems. First, regarding waterproofing, traditional methods often fail to adequately address the sealing of joints, allowing rainwater to easily seep into the interior space, especially under inclement weather conditions. Second, due to the lack of effective concealment measures, fasteners and joints are often exposed, affecting the building's overall aesthetics and potentially accelerating material aging due to prolonged exposure.

[0003] In addition, traditional installation techniques also face challenges in terms of construction efficiency and cost control. Because the fixing of interior panels and roof panels needs to be handled separately, on-site operations become complex and time-consuming, increasing both construction difficulty and labor costs. Moreover, without pre-set uniform supports and fixing bases, material waste is common, which is detrimental to environmental protection and resource conservation. Furthermore, with the impact of climate change, building materials, especially metals, undergo thermal expansion and contraction. Traditional installation structures lack sufficient flexibility to adapt to these changes, easily causing damage or deformation at connection points, thus affecting the safety and durability of the entire building structure.

[0004] Therefore, given the shortcomings of the existing technologies, it is particularly important to develop a new type of parapet wall inner panel lower installation structure that can effectively improve waterproofing performance, enhance aesthetics, simplify the installation process, and has good temperature adaptability. Such technological improvements will not only help solve current practical problems but also provide more flexible and diverse solutions for architectural design. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, this utility model discloses a parapet wall inner panel lower end installation structure.

[0006] To achieve the above-mentioned objectives, the present invention adopts the following technical solution:

[0007] A parapet wall inner panel lower end mounting structure, comprising:

[0008] The inner panel is laid along the inner side of the parapet wall columns;

[0009] The roof slab is laid along the roof beams, with one end extending to the parapet wall;

[0010] The connecting profile is installed on the bottom inner side of the parapet column; the connecting profile has a first bending structure and a second bending structure with staggered heights; the first bending structure is used to fix the inner panel, and the second bending structure is used to fix the roof panel.

[0011] Preferably, both the first bending structure and the second bending structure are sloping structures, and the first bending structure can block the second bending structure.

[0012] Preferably, the top of the second bending structure is spaced apart from the rest of the connecting profile; the edge of the roof panel is provided with a bending structure that engages with the top of the second bending structure.

[0013] Preferably, the connecting profile has a right-angle bend structure at the bottom corresponding to the second bend structure; the roof panel has an arc-shaped bend at the location corresponding to the right-angle bend structure.

[0014] Preferably, the bottom of the inner panel extends along the first bending structure or bends towards the second bending structure to press against the roof panel.

[0015] Preferably, the connecting profile is an aluminum profile or a sheet metal bending part.

[0016] By adopting the technical solution described above, this utility model has the following beneficial effects:

[0017] (1) This utility model achieves a stable connection and seal between the inner panel and the roof panel through the optimized design of the connecting profile. The connecting profile adopts an integral molding structure with a first bend and a second bend structure with staggered heights, which are used to fix the inner panel and the roof panel respectively, ensuring the stability of the overall structure and good sealing performance. The first bend can cover the second bend and the closing part of the roof panel at the parapet wall in the vertical projection, which not only improves the neatness of the appearance, but also forms a physical water barrier and enhances the rainproof effect.

[0018] (2) This utility model further designs the first and second bending structures as slopes, tilting downwards away from the parapet wall, thereby effectively guiding water flow outwards and preventing rainwater from accumulating at the connection point, significantly improving rainproof performance. The bottom of the inner panel is adjusted according to this slope design, either extending downwards along the slope of the first bending structure or bending inwards so that its end fits tightly against the upper surface of the roof panel. This not only reduces the possibility of rainwater infiltration but also enhances the aesthetics of the building facade. At the same time, in order to ensure the installation accuracy and stability of the roof panel, the "first snap-fit ​​then nail" installation method is introduced, that is, the snap-fit ​​part of the edge of the roof panel is first pre-positioned and snapped with the second bending structure, and then fastened with self-tapping screws, ensuring the accuracy and firmness of the installation.

[0019] (3) This utility model further considers the impact of temperature changes on the roof panel and incorporates a thermal expansion compensation mechanism. An inwardly extending right-angle bending structure is provided at the bottom position of the connecting profile corresponding to the second bending structure, while the roof panel is provided with a corresponding arc-shaped bending part. When the ambient temperature changes and causes the roof panel to elongate or contract, the arc-shaped bending part can slide moderately inside the right-angle bending structure, thereby releasing stress and preventing structural damage or sealing failure caused by thermal expansion and contraction.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0026] In the description of this utility model, it should be noted that the terms "upper" and "lower" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the utility model product is usually placed during use. They are only used to facilitate the description of this utility model and to simplify the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0027] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0028] Example 1:

[0029] Combined with appendix Figures 1-4 A parapet wall inner panel mounting structure includes an inner panel 1, a roof panel 2, and connecting profiles 3. The inner panel 1 is laid along the inner columns of the parapet wall to enclose the inner space of the parapet wall, forming part of the interior wall surface. The roof panel 2 is laid along the direction of the building's roof beams, with its end near the parapet wall extending to the base of the parapet wall to achieve a continuous transition between the roof and the wall.

[0030] A connecting profile 3 is pre-installed on the inner bottom of the parapet wall column. This connecting profile 3 serves as a shared support and fixing base for the inner panel 1 and the roof panel 2. The connecting profile 3 is a one-piece molded structure with a first bending structure 3-1 and a second bending structure 3-2 arranged at different heights. The first bending structure 3-1 is located at a higher position and is used to fasten it to the lower end of the inner panel 1 with screws. The second bending structure 3-2 is located at a lower position and is used to support and fix the end of the roof panel 2.

[0031] It is worth noting that the first bending structure 3-1, in its vertical projection, can cover the second bending structure 3-2 and the closing part of the roof panel 2 at the parapet wall, thus effectively concealing the seams and fasteners in that area. This not only improves the overall neatness of the appearance but also forms a physical water barrier, enhancing rainproof performance. The connecting profile 3 can be made of aluminum profile or sheet metal bending parts. Because it is a continuous linear component, it is easy to mass-produce and install on-site, which helps to reduce material waste and production costs.

[0032] During the installation process, the connecting profile 3 is first fixed to the designated position on the bottom of the inner side of the parapet column; then, the end of the roof panel 2 is aligned with the second bending structure 3-2 and fastened to the connecting profile 3 with self-tapping screws; after all the roof panels 2 are installed, the inner panel 1 is laid from top to bottom, and its bottom is aligned with the first bending structure 3-1. Finally, the inner panel 1 is reliably connected to the first bending structure 3-1 with screws to complete the overall assembly.

[0033] Example 2:

[0034] Combined with appendix Figures 1-4The parapet wall inner panel lower end installation structure described in this embodiment is an optimized version of Embodiment 1. The main difference from Embodiment 1 is that both the first bending structure 3-1 and the second bending structure 3-2 are designed as sloping structures, that is, both are inclined downwards away from the parapet wall to form a slope that guides water flow outwards.

[0035] Based on this, the first bending structure 3-1 is still higher than the second bending structure 3-2 in spatial position, and its extension length is sufficient to cover the upper surface of the second bending structure 3-2 and the end area of ​​the roof panel 2, thereby further enhancing the drainage guidance function, preventing rainwater from accumulating at the connection, and significantly improving the overall rainproof effect.

[0036] Furthermore, the bottom of the inner panel 1 can extend downward along the slope of the first bending structure 3-1, so that it forms a continuous shielding surface with the connecting profile 3, reducing the possibility of rainwater infiltration; or, the bottom of the inner panel 1 can also be bent inward so that its end abuts against the upper surface of the roof panel 2. This can not only further shield the edge structure of the roof panel 2 at the parapet wall, but also enhance the overall sealing and visual consistency of the connecting area, and improve the aesthetics of the building facade.

[0037] In addition, a gap is reserved between the top of the second bending structure 3-2 and the main body of the connecting profile 3, which is used to accommodate the special bending structure set at the end of the roof panel 2.

[0038] Specifically, the edge of the roof panel 2 is provided with a downwardly bent engagement part, which can first be pre-positioned and engaged with the top of the second bending structure 3-2, and then the roof panel 2 and the second bending structure 3-2 are finally fastened together with self-tapping screws. This "first engage, then fasten" installation method helps to improve the installation accuracy and stability of the roof panel 2 and avoid gaps or misalignment caused by positioning deviation.

[0039] Furthermore, the connecting profile 3 has an inwardly extending right-angle bend structure at the bottom position corresponding to the second bend structure 3-2, while the roof panel 2 has a matching arc-shaped bend in the corresponding area. The function of the arc-shaped bend is to accommodate the thermal expansion and contraction deformation of the roof panel 2 caused by temperature changes: when the ambient temperature rises and causes the roof panel 2 to elongate, the arc-shaped bend can slide further into the right-angle bend structure; when the temperature drops and causes the roof panel 2 to shrink, the arc-shaped bend can be appropriately withdrawn from the right-angle bend structure, thereby releasing stress and preventing the structure from warping, cracking, or loosening due to restricted deformation.

[0040] It is important to note that during installation, a reasonable initial gap must be maintained between the curved bend of the roof panel 2 and the vertical step surface of the right-angle bend structure. This gap should be sufficient to accommodate the displacement of the roof panel 2 under maximum thermal expansion. Otherwise, under high temperature conditions, the curved bend may press against the right-angle step surface, causing the compensation mechanism to fail and leading to structural damage or sealing failure.

[0041] The parts of this utility model not described in detail are prior art. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that this utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects, and are intended to include all changes that fall within the meaning and scope of equivalents within this utility model.
