Description

Technical Field

[0001] This utility model relates to the field of steel structure roofing technology, and in particular to a sliding and telescopic connection structure between a steel structure roof panel and a gable wall panel. Background Technology

[0002] In the field of steel structure construction, the connection structure design between the roof slab and gable slab is crucial to the overall performance of the building. Traditional connection methods often employ rigid fixing. While this method provides a certain level of structural strength, it is prone to a series of problems when faced with material expansion and contraction due to changes in ambient temperature, dimensional errors during construction, and material deformation after long-term use. For example, due to the high coefficient of thermal expansion of steel, the roof slab will undergo significant expansion and contraction along its length under the influence of different seasons and diurnal temperature variations. If a rigid connection is used, it may lead to large internal stresses between the slabs, which in severe cases may even cause cracking of the slabs or loosening of the connection, thereby affecting the building's airtightness and safety.

[0003] Furthermore, the conditions at construction sites are complex and variable, making it difficult to completely avoid manufacturing tolerances and installation deviations. Traditional connection structures typically lack effective adjustment mechanisms to compensate for these unavoidable errors. This not only increases installation difficulty but may also lead to component damage or weak connections due to forced mating. To overcome these problems, it is sometimes necessary to add extra elastic gaskets or other complex adjustment mechanisms, which undoubtedly increases material costs and construction complexity, and may reduce the reliability and durability of the system to some extent.

[0004] Therefore, designing a steel roof and gable wall connection structure that can effectively adapt to material deformation caused by environmental factors and easily and quickly resolve various errors that may occur during installation has become a pressing technical challenge in current steel structure building design. Existing solutions still have shortcomings in terms of flexibility, ease of use, and economy, and further improvements are needed to meet the needs of modern construction projects. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, this utility model discloses a sliding and telescopic connection structure between a steel roof panel and a gable panel.

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

[0007] A sliding and telescopic connection structure between a steel roof panel and a gable wall panel includes:

[0008] A gable wall panel is installed on a gable wall steel column; the surface of the gable wall panel is provided with a bent protrusion, and the bottom of the bent protrusion is provided with a right-angle mounting cavity;

[0009] The sliding connectors are arranged in multiple intervals along the gable panel; the bottom of each sliding connector is provided with an angle-adjustable hook; and the hook extends into the right-angle mounting cavity of the gable panel;

[0010] The roof panel has an upward-facing bend on one side corresponding to the gable panel. The edge of the bend has a downward-facing U-shaped bend that is hooked to the hook of the sliding connector. The installation or dimensional error of the roof panel can be compensated by adjusting the angle of the hook. The right-angle mounting cavity of the gable panel provides adjustment space for the error of the roof panel.

[0011] Preferably, the sliding connector includes:

[0012] Connecting plate, fixedly connected to the gable wall panel;

[0013] The curved bending plate is connected to the bottom of the connecting plate;

[0014] The hook head connects to the bottom of the curved bending plate; the hook head and the curved bending plate together form the hook part of the sliding connector; the angle of the hook part is adjusted by bending the curved bending plate.

[0015] Preferably, the arc-shaped bending plate has a C-shaped or S-shaped structure.

[0016] Preferably, the edge of the hook head is provided with a circular bend, which corresponds to and abuts against the top of the U-shaped bend of the roof panel.

[0017] Preferably, the connecting plate, the arc-shaped bending plate, and the hook are an integral bending structure.

[0018] Preferably, the connecting plate has mounting holes on its surface.

[0019] By adopting the technical solution described above, this utility model has the following beneficial effects:

[0020] (1) This utility model has a simple structure. The gable panel has a bent protrusion on its surface and a right-angle mounting cavity at the bottom to accommodate the hook part of the sliding connector. This design not only provides a stable support base for the hook, but also allows the hook to adjust its angle within a certain range to accommodate slight offsets in the position of the roof panel. In this way, even under manufacturing tolerances or on-site construction deviations, it can be ensured that the sliding connector can be smoothly attached to the U-shaped bend of the roof panel. In addition, the design of the right-angle mounting cavity enables the entire connection structure to absorb the thermal expansion and contraction deformation of the roof panel, effectively avoiding problems such as panel cracking, loose connection, or sealing failure caused by rigid constraints.

[0021] (2) Multiple sliding connectors of this utility model are spaced apart along the length of the gable panel, and each sliding connector has an adjustable hook at its bottom. This layout ensures that installation errors in the width direction of the roof panel can be effectively compensated. No additional elastic pads or other complex adjustment mechanisms are required, simplifying the installation process and improving the reliability of the connection. This structure can adapt to the needs of use under different environmental conditions, enhancing the overall safety and durability of the building.

[0022] (3) This utility model further refines the design of the sliding connector, comprising three parts: a connecting plate, an arc-shaped bending plate, and a hook. The connecting plate is fixed to the gable plate with self-tapping screws through mounting holes on its surface, ensuring the stability of the overall structure. In particular, the arc-shaped bending plate adopts a C-shaped or S-shaped structure, which enhances the overall rigidity of the connector under stress and also provides a uniform stress distribution during bending adjustment, avoiding local stress concentration that could lead to material fatigue or fracture. This feature not only extends the service life of the connector but also improves the safety of the entire system.

[0023] (4) The free end edge of the hook of this utility model is provided with a circular bend edge, which contacts the top of the U-shaped bend edge of the roof panel to form a sliding mating surface. The design of the circular bend edge effectively disperses the contact pressure, reduces frictional resistance, and ensures that the roof panel can slide smoothly under temperature changes or wind pressure, maintaining the expansion and contraction function of the structure. In addition, the connecting plate, the arc-shaped bend plate and the hook are integrally formed by continuous bending process from the same metal plate, which not only ensures the structural continuity and mechanical integrity between the components, but also simplifies the manufacturing process, reduces production costs and improves on-site installation efficiency.

[0028] 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.

[0029] 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.

[0030] 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.

[0031] Example 1:

[0032] Combined with appendix Figures 1-2 A sliding and telescopic connection structure between a steel roof panel and a gable wall panel includes a gable wall panel 1, sliding connectors 2, and a roof panel 3. The gable wall panel 1 is mounted on a steel gable wall column. The surface of the gable wall panel 1 has a bent protrusion, the bottom of which forms a right-angle mounting cavity to accommodate the hook portion of the sliding connector 2. Multiple sliding connectors 2 are spaced apart along the length of the gable wall panel 1. Each sliding connector 2 has an angle-adjustable hook portion at its bottom, which extends upwards into the right-angle mounting cavity of the gable wall panel 1 and can be adjusted within a certain range of angles within the cavity, as shown in the attached diagram. Figure 2 As shown by the arrow in the image.

[0033] The roof panel 3 has an upward-facing bend on the side near the gable panel 1. The edge of this bend is further bent downwards to form a downward-facing U-shaped bend. This U-shaped bend engages with the hook of the sliding connector 2, forming a slidable mechanical connection. During actual installation, due to manufacturing tolerances or on-site construction deviations, the position of the roof panel 3 may slightly shift. In this case, the angle of the hook of the sliding connector 2 can be adjusted manually or with tools to ensure smooth engagement with the U-shaped bend of the roof panel 3. The right-angle mounting cavity in the gable panel 1 provides the necessary space for the hook, enabling the entire connection structure to adapt and adjust. This effectively absorbs thermal expansion and contraction deformation of the roof panel 3 along its length and installation errors along its width, avoiding problems such as panel cracking, loose connections, or sealing failure caused by rigid constraints. This structure eliminates the need for additional elastic gaskets or complex adjustment mechanisms, simplifying the installation process and improving connection reliability.

[0034] Example 2:

[0035] Combined with appendix Figures 1-3 A sliding telescopic connection structure between a steel roof panel and a gable wall panel is disclosed. The difference from Embodiment 1 lies in the detailed design of the sliding connector 2, which is based on Embodiment 1. The sliding connector 2 includes a connecting plate 2-1, an arc-shaped bending plate 2-2, and a hook 2-3. The connecting plate 2-1 is fixed to the outer side of the bent protrusion of the gable wall panel 1 using self-tapping screws through mounting holes on its surface, ensuring a stable overall connection. The bottom of the connecting plate 2-1 extends downwards and is integrally connected to the arc-shaped bending plate 2-2. The arc-shaped bending plate 2-2 then connects downwards to the hook 2-3, and the three together constitute the complete sliding connector 2. The hook 2-3, combined with the arc-shaped bending plate 2-2, forms the aforementioned angle-adjustable hook portion. By manually bending the middle area of ​​the arc-shaped bending plate 2-2, the overall angle of the hook portion can be continuously adjusted to adapt to the position of the roof panel 3 under different installation conditions.

[0036] Furthermore, the curved bending plate 2-2 adopts a C-shaped or S-shaped structure. This structure not only enhances the overall rigidity of the connector under stress but also provides a uniform stress distribution during bending adjustment, avoiding localized stress concentration that could lead to material fatigue or fracture. Simultaneously, the C-shaped or S-shaped geometry endows the curved bending plate 2-2 with a certain degree of elastic recovery, maintaining a stable hook angle after adjustment and preventing accidental deflection due to vibration or wind load.

[0037] Furthermore, the free end edge of the hook 2-3 is provided with a circular bend, which contacts the inner top of the U-shaped bend of the roof panel 3 and forms a sliding mating surface. Since the edge of the U-shaped bend of the roof panel 3 may have burrs, minor unevenness, or dimensional fluctuations during processing, direct contact with a sharp or flat hook can easily cause jamming, wear, or increased sliding resistance. The circular bend, however, has a smooth, curved surface feature that effectively disperses contact pressure, reduces frictional resistance, and ensures that the roof panel 3 can slide smoothly along the hook under temperature changes or wind pressure, maintaining the structure's expansion and contraction function.

[0038] The connecting plate 2-1, the arc-shaped bending plate 2-2, and the hook 2-3 are integrally formed from the same piece of metal sheet through a continuous bending process, eliminating the need for welding or splicing. This ensures the structural continuity and mechanical integrity between the components and avoids performance degradation caused by loosening or corrosion of the connection nodes. The integrated structure also simplifies the manufacturing process, reduces production costs, and improves on-site installation efficiency, while ensuring that all sliding connectors 2 have highly consistent geometric accuracy and adjustability.

[0039] 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.
