Description

Technical Field

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

[0002] In current building roofing systems, the ridge, as a key component of the roof structure, not only bears important functions such as waterproofing, windproofing, and structural connection, but also directly affects the overall durability and aesthetics of the roof. However, existing ridge end installation structures generally have several significant defects, making it difficult to meet the requirements of modern buildings for high-performance roofing systems.

[0003] Traditional ridge panels are often rigidly fixed to the supporting structure, failing to adequately consider the thermal expansion and contraction effects of metals or composite materials under diurnal temperature variations or seasonal temperature changes. This rigid constraint causes the ridge panel to accumulate internal stress during repeated deformation, easily leading to warping, cracking, and even loosening of connections, potentially causing roof leaks or structural failure. Secondly, while some existing solutions attempt to mitigate thermal deformation by leaving gaps, these gaps often lack effective dynamic sealing measures. They fail to prevent the intrusion of rainwater, dust, and other external media, and visually disrupt the continuity of the ridge lines, affecting the overall architectural appearance. Existing ridge end structures also suffer from insufficient connection stability. Most designs rely solely on static connections such as screws or welding to fix the panel to the end profiles, lacking effective mechanisms to constrain vertical displacement. Under strong winds or snow loads, the ends of the ridge panel are prone to warping or vibration, leading to seal failure and even the risk of detachment. Especially at the ridge ends with parapet walls, traditional construction often neglects the coordinated stress distribution and sealing between the cover plate and the wall, allowing rainwater to easily seep into the building along the junction of the wall and the ridge, causing secondary problems such as damp walls and insulation failure. Existing technologies often use rigid materials for covering expansion joints; while they offer some concealment, they cannot expand and contract synchronously with the thermal deformation of the ridge cover plate, potentially becoming obstacles to deformation and exacerbating structural stress.

[0004] In summary, existing ridge end installation structures have significant shortcomings in terms of thermal deformation adaptability, dynamic sealing performance, connection stability, and collaborative construction with the parapet wall. There is an urgent need for a new installation structure that can balance structural stability, deformation adaptability, and long-term sealing reliability in order to improve the overall performance and service life of the roof system. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, this utility model discloses a roof ridge end installation structure.

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

[0007] A ridge end mounting structure, comprising:

[0008] The ridge cap has a herringbone structure;

[0009] An end profile is installed at one end of the ridge cover plate, and an expansion joint is left between the end face of the ridge cover plate and the end profile; the end profile is used to support the end of the ridge cover plate.

[0010] A sliding assembly, installed between the end profile and the ridge cap; used to allow the ridge cap to slide against the end profile.

[0011] An elastic cap is placed over the end of the ridge cap plate to seal the expansion joint between the end face of the ridge cap plate and the end profile.

[0012] Preferably, the end profile includes:

[0013] The top structure of the support section corresponds to and is adapted to the shape of the ridge cover plate; both sides of the bottom of the support section are provided with bending structures.

[0014] There are two wing plates, which are respectively located on both sides of the support; the ridge cover plate has a groove bending structure on both sides that respectively engages with the two wing plates.

[0015] Preferably, the end of the support portion facing away from the ridge cover plate is provided with a connecting plate.

[0016] Preferably, the sliding component includes:

[0017] Two dovetail grooves are located on both sides of the end profile;

[0018] Two sliders are respectively slidably engaged with two dovetail grooves; the ridge cover plate is fastened to the two sliders by screws.

[0019] Preferably, both ends of the dovetail groove are sealed, and both ends of the corresponding slider inside the dovetail groove are filled with rubber blocks.

[0020] Preferably, the slider is a nylon block or a wooden block.

[0021] Preferably, the resilient cap is glued to the ridge cap or fastened with screws.

[0022] By adopting the technical solution described above, this utility model has the following beneficial effects:

[0023] (1) This utility model effectively adapts to the thermal expansion and contraction deformation of the ridge cover plate caused by temperature changes through the expansion joint reserved between the ridge cover plate and the end profile, avoiding structural stress concentration, warping or cracking caused by restricted deformation, thereby significantly improving the structural stability and service life of the roof system. The top of the support part of the end profile fits tightly with the bottom contour of the ridge cover plate, providing reliable support. The bending structure on both sides of its bottom not only enhances the overall rigidity and load-bearing capacity of the profile, but also facilitates a firm connection with the roof beam below through fasteners, ensuring stable installation. The wing plates set on both sides of the support part cooperate with the corresponding slot bending structure of the ridge cover plate to form a snap-fit ​​connection, effectively limiting the vertical displacement of the ridge cover plate and preventing it from warping under wind pressure or its own weight, thereby improving the roof sealing performance and wind resistance.

[0024] (2) In the case of a parapet wall, the connecting plate added to the end profile on the side away from the ridge cover plate can be reliably connected to the parapet wall, further enhancing the overall stability and effectively preventing rainwater from seeping into the wall along the gap.

[0025] (3) The introduction of the sliding component of this utility model realizes the sliding connection between the ridge cover plate and the end profile, so that the ridge cover plate can freely expand and contract during thermal expansion and contraction, avoiding structural damage. In particular, in the structure of using dovetail groove and slider, the slider is connected to the ridge cover plate by screws and slides along the dovetail groove. It has good guidance and is not easy to fall out. At the same time, the sealing structure at both ends of the groove and the rubber block inside work together to restrict the unexpected movement of the slider while not hindering its normal sliding during temperature deformation, thus taking into account both structural stability and deformation adaptability.

[0026] (4) The elastic cap covering the expansion joint of this utility model not only effectively covers the gap and prevents rainwater from seeping in, but also has good elastic deformation ability and can expand and contract synchronously with the ridge cover plate without hindering its free deformation. At the same time, it is fixed by adhesive or screws to ensure that it is not easy to fall off in wind or vibration environment, thus improving the overall aesthetics and durability of the ridge end.

[0035] Example 1:

[0036] Combined with appendix Figures 1-4 A ridge end installation structure includes a ridge cover plate 1, an end profile 2, a sliding component 3, and an elastic cap 4. The ridge cover plate 1 has a herringbone shape and its main function is to cover the top of the ridge and prevent rainwater from seeping into the roof system. An end profile 2 is installed at one end of the ridge cover plate 1, and an expansion joint is provided between the end face of the ridge cover plate 1 and the end profile 2. This expansion joint can effectively accommodate the thermal expansion and contraction deformation of the ridge cover plate 1 due to temperature changes, preventing structural deformation or damage due to stress concentration. The end profile 2 supports the end of the ridge cover plate 1, ensuring its structural stability during installation and use.

[0037] Specifically, as shown in the attached document Figure 4The end profile 2 includes a support portion 2-1 and a wing plate 2-2. The top structure of the support portion 2-1 matches the bottom contour of the ridge cover plate 1, allowing it to fit tightly against the ridge cover plate 1 and provide effective support. Both sides of the bottom of the support portion 2-1 are provided with bending structures. These bending structures serve two purposes: firstly, to enhance the overall rigidity of the end profile 2 and improve its load-bearing capacity; and secondly, to facilitate a reliable connection between the end profile 2 and the underlying roof beam structure using fasteners, ensuring the stability of the overall installation structure.

[0038] Wing plates 2-2 are provided on both sides of the support 2-1; corresponding slotted bending structures are provided on both sides of the ridge cover plate 1. These slotted bending structures cooperate with the wing plates 2-2 to achieve a snap-fit ​​connection between the ridge cover plate 1 and the end profile 2. This snap-fit ​​structure can limit the vertical displacement of the ridge cover plate 1 and prevent its end from warping under wind pressure or its own weight, thereby improving the sealing and durability of the roof system. If a parapet wall is provided at this end of the ridge cover plate 1, a connecting plate 2-3 is provided on the side of the support 2-1 away from the ridge cover plate 1. The connecting plate 2-3 is connected to the parapet wall structure by fasteners, further enhancing the overall stability of the ridge end and preventing rainwater from seeping into the wall along the gaps.

[0039] A sliding assembly 3 is installed between the end profile 2 and the ridge cover plate 1. The sliding assembly 3 is used to realize the sliding connection between the ridge cover plate 1 and the end profile 2, so that the ridge cover plate 1 can slide freely relative to the end profile 2 during thermal expansion and contraction, avoiding structural stress or damage due to deformation restriction.

[0040] An elastic cap 4 is installed above the end of the ridge cover plate 1. This elastic cap 4 covers the expansion joint between the end face of the ridge cover plate 1 and the end profile 2, serving to both conceal the gap and prevent rainwater seepage, while also improving the overall appearance of the ridge end. Depending on the actual installation requirements, the elastic cap 4 can be connected to the ridge cover plate 1 by adhesive or screw fastening to prevent accidental detachment due to wind or vibration during use. Furthermore, because the elastic cap 4 has a certain degree of elastic deformation capability, it can deform synchronously with the ridge cover plate 1 when it undergoes thermal expansion and contraction, without hindering the free expansion and contraction of the ridge cover plate 1.

[0041] Example 2:

[0042] Combined with appendix Figures 1-4 A roof ridge end mounting structure, which differs from Embodiment 1 in that: based on Embodiment 1, as shown in the attached... Figure 4As shown, the sliding assembly 3 specifically includes two dovetail grooves 3-1 and two sliders 3-2. The two dovetail grooves 3-1 are respectively located on both sides of the end profile 2, and their cross-section is dovetail-shaped, used to guide the sliding direction of the sliders 3-2 and restrict their disengagement. The two sliders 3-2 are slidably engaged with the two dovetail grooves 3-1 respectively. The ridge cover plate 1 is fastened to the two sliders 3-2 by screws, thereby indirectly connecting the ridge cover plate 1 to the end profile 2. When the ridge cover plate 1 undergoes thermal expansion and contraction due to temperature changes, it can drive the sliders 3-2 to slide along the corresponding dovetail grooves 3-1, realizing the free expansion and contraction of the structure and avoiding stress concentration. The sliders 3-2 can be made of materials with certain strength and easy processing, such as nylon blocks or wooden blocks, facilitating a reliable connection between the ridge cover plate 1 and the sliders 3-2 using self-tapping screws, while also considering sliding performance and ease of installation.

[0043] Furthermore, both ends of the dovetail groove 3-1 are sealed to prevent the slider 3-2 from detaching during sliding. Inside the dovetail groove 3-1, at the corresponding ends of the slider 3-2, rubber blocks 3-3 are respectively filled. The rubber blocks 3-3 are elastic, providing elastic restraint to the slider 3-2 when it is in its normal position, preventing it from sliding freely without external force, thus avoiding unexpected displacement of the roof cover 1. Simultaneously, when the roof cover 1 deforms due to thermal expansion and contraction, causing the slider 3-2 to slide, the rubber blocks 3-3 can be moderately compressed or rebounded, without hindering the normal sliding of the slider 3-2, ensuring the structure's free expansion and contraction function under temperature changes is realized.

[0044] 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.
