Description

Technical Field

[0001] This utility model relates to the field of prefabricated building technology, and in particular to a hanging structure for purlinless roof systems. Background Technology

[0002] As an important roofing form in the field of prefabricated buildings, purlinless roofing systems are mainly composed of secondary beams and Jingnuo composite panels. The Jingnuo composite panels are ribbed bimetallic sandwich panels with excellent ultimate bending strength, and the maximum span can reach 4-6 meters. This system integrates thermal insulation and waterproofing functions, not only providing a stable and reliable structure but also exhibiting excellent performance in core areas such as waterproofing, wind resistance, heat insulation, and sound absorption. It is currently widely used in industrial buildings, public venues, transportation hubs, and commercial buildings, becoming a preferred roofing solution for modern large-span, large-space buildings.

[0003] In practical applications of purlin-free roofing systems, hanging structures (such as sprinkler system hangers, pipe hangers, and lighting hangers) need to be installed according to the building's functional requirements. Taking sprinkler hangers commonly used in industrial buildings as an example, according to relevant specifications, the number of pipe hangers between two adjacent sprinkler heads should not be less than one, and the hanger spacing should not exceed 3.6m. This spacing requirement is smaller than the 4-6m span of the purlin-free roofing system and the spacing of secondary beams, which necessitates the direct installation of hanging nodes on the roof panels or secondary beams. Existing conventional hanging nodes are mostly installed using methods such as drilling holes and welding fasteners. However, drilling holes or welding operations will damage the integrity of the purlin-free roofing system's roof panels, resulting in impaired thermal insulation and waterproofing performance. At the same time, it will weaken the original structural load-bearing capacity of the roof panels and secondary beams, increasing the risk of roof system deformation and leakage.

[0004] Therefore, designing a hanging structure that does not damage the integrity of the roof panel, is compatible with its span and component structure, is easy to install, and has a reliable structure has become a key requirement for solving the current hanging problem of purlinless roof systems. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides a hanging structure for purlinless roof systems.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a hanging structure for a purlinless roof system, comprising connectors, fasteners, and hanging components. The connector is compatible with the structural components of the purlinless roofing system; The fastener is used to detachably and securely connect the connector to the structural components of the purlinless roof system, and the fastener as a whole does not penetrate the surface of the roof panel of the purlinless roof system. The hanging component is located at the bottom of the connector and is used to connect external hanging parts.

[0007] Furthermore, the connector includes an upward-opening grooved plate, the cross-sectional profile of which matches the cross-sectional profile of the inner rib of the roof panel of the purlinless roof system. Two through holes are spaced apart on the two sides of the grooved plate. The fastener includes two fixing bolts, which pass through the two through holes and the inner rib of the roof panel to fix the grooved plate to the inner rib of the roof panel. The hanger includes a hanging plate, the upper end of which is fixedly positioned at the middle of the bottom of the groove of the grooved plate. The hanging plate has mounting holes.

[0008] Furthermore, the connecting component includes upper angle steel and lower angle steel, the length directions of which are perpendicular to the length direction of the secondary beam of the purlinless roof system. There are two upper angle steels, respectively located on both sides of the top surface of the lower flange plate of the secondary beam, and one lower angle steel, located on the bottom surface of the lower flange plate of the secondary beam. The fixing component includes two connecting bolts, which are used to connect the two upper angle steels to the lower angle steel. The hanging component includes a fixing plate located on the vertical plate edge of the lower angle steel, and a hanging rod is provided on the fixing plate.

[0009] Furthermore, a spacer is provided between the upper angle steel and the lower angle steel, and the thickness of the spacer is the same as the thickness of the lower flange plate of the secondary beam. The connecting bolt passes through the upper angle steel, the spacer, and the lower angle steel to connect the upper angle steel and the lower angle steel.

[0010] Furthermore, the fixing plate and the lower angle steel are connected by fastening bolts.

[0011] Furthermore, the overlap length between the upper angle steel and the lower flange plate of the secondary beam is not less than 55mm.

[0012] Furthermore, the upper end of the hanging rod has a notch with the same thickness as the fixing plate, and the notch of the hanging rod is fitted with the fixing plate and connected by welding.

In this way, hanging components can be installed on the purlinless roofing system, solving the problem of mismatch between the hanging point spacing and the span of the panel. It can also fundamentally avoid damage to the metal surface layer of the roof panel and the internal thermal insulation and waterproofing structure, effectively preventing problems such as roof leakage and decreased thermal insulation performance caused by hanging installation, and ensuring the original structural load-bearing capacity and building function of the purlinless roofing system.

[0016] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0017] like Figure 1 As shown, this application discloses a hanging structure for a purlin-less roof system, including connectors, fasteners, and hangers. The connectors are adapted to the structural components of the purlin-less roof system; the fasteners are used to detachably and securely connect the connectors to the structural components of the purlin-less roof system, and the fasteners as a whole do not penetrate the surface layer of the roof panel of the purlin-less roof system; the hangers are located at the bottom of the connectors and are used to connect external hanging components. By setting connectors adapted to the structural components of the purlin-less roof system, and then connecting the connectors to the structural components of the purlin-less roof system through the fasteners, and ensuring that the fasteners as a whole do not penetrate the surface layer of the roof panel of the purlin-less roof system, hangers can be installed on the purlin-less roof system. This solves the problem of mismatch between the hanging point spacing and the slab span, and fundamentally avoids damage to the metal surface layer and internal insulation and waterproofing structure of the roof panel. It effectively prevents roof leakage and decreased insulation performance caused by hanging installation, ensuring the original structural load-bearing capacity and building function of the purlin-less roof system. Example 1

[0018] like Figure 2-4 As shown, this embodiment discloses a hanging structure for a purlinless roof system, including connectors, fasteners, and hanging components.

[0019] Specifically, the connector includes an upward-opening channel plate 1, the fastener includes two fixing bolts 3, and the hanger includes a hanging plate 4. The cross-sectional profile of the channel plate 1 matches the cross-sectional profile of the inner rib of the roof panel of the purlinless roofing system, thus ensuring that the channel plate 1 can be snapped onto the inner rib of the roof panel of the purlinless roofing system. Two through holes 2 are opened at intervals on both sides of the channel plate 1. During construction, two transverse holes need to be made at the positions on the inner rib of the roof panel where the channel plate 1 is installed, corresponding to the two through holes 2. Then, the channel plate 1 is snapped onto the inner rib of the roof panel of the purlinless roofing system. The screws of the two fixing bolts 3 are passed through the two through holes 2 and the inner rib of the roof panel, respectively. Then, the nuts of the fixing bolts 3 are tightened to fix the channel plate 1 onto the inner rib of the roof panel, thus installing the channel plate 1 onto the roof panel. In this way, the two fixing bolts 3 are located on the inner rib of the roof panel and will not penetrate the surface of the roof panel, thus effectively avoiding problems such as roof leakage and reduced thermal insulation performance, and ensuring the original structural load-bearing capacity and building function of the purlinless roof system.

[0020] The upper end of the hanging plate 4 is fixedly positioned at the middle of the bottom of the channel plate 1, ensuring uniform load distribution. The hanging plate 4 and the channel plate 1 can be welded together, ensuring a stable connection and strong resistance to loosening. The hanging plate 4 and the channel plate 1 can be pre-welded together before leaving the factory. Factory welding ensures welding accuracy and production efficiency, and eliminates the need for on-site welding, reducing construction costs. Mounting holes 5 are provided on the hanging plate 4 for bolting pipe hangers. Example 2

[0021] like Figure 5-6 As shown, this embodiment discloses a hanging structure for a purlinless roof system, including connectors, fasteners, and hanging components.

[0022] Specifically, the connectors include upper angle steel 11 and lower angle steel 12, the fasteners include two connecting bolts 13, and the hangers include a fixing plate 14 and a hanging rod 15. The length directions of both upper angle steel 11 and lower angle steel 12 are perpendicular to the length direction of the secondary beams in the purlinless roof system. There are two upper angle steels 11, respectively located on both sides of the top surface of the lower flange plate of the secondary beam, and one lower angle steel 12, located on the bottom surface of the lower flange plate of the secondary beam. Thus, the upper angle steels 11 and lower angle steel 12 clamp the lower flange plate of the secondary beam. Concentric bolt holes are provided on the upper angle steels 11 and lower angle steel 12. The two connecting bolts 13 are used to connect the two upper angle steels 11 to the lower angle steel 12. Under the tightening action of the connecting bolts 13, the upper angle steels 11 on both sides and the lower angle steel 12 below are tightly clamped onto the lower flange plate of the secondary beam, thereby fixing the upper angle steels 11 and lower angle steel 12 onto the lower flange plate of the secondary beam. The fixing process does not require drilling holes in the lower flange of the secondary beam, thus ensuring the structural integrity of the lower flange of the secondary beam and preventing damage to the original structural load-bearing capacity and building function of the purlinless roof system.

[0023] Furthermore, a spacer 16 is provided between the upper angle steel 11 and the lower angle steel 12. The spacer 16 has through holes corresponding to the bolt holes of the upper angle steel 11 and the lower angle steel 12. The connecting bolt 13 passes through the upper angle steel 11, the spacer 16, and the lower angle steel 12 to connect the upper angle steel 11 and the lower angle steel 12. The thickness of the spacer 16 is the same as the thickness of the lower flange plate of the secondary beam. The spacer 16 is positioned where the upper angle steel 11 and the lower angle steel 12 protrude from the lower flange plate of the secondary beam, filling the gap between the upper angle steel 11 and the lower angle steel 12 outside the lower flange plate of the secondary beam. This prevents tilting due to the gap between the upper angle steel 11 and the lower angle steel 12 when tightening the connecting bolt 13, thus reducing the clamping force on the lower flange plate of the secondary beam.

[0024] To further ensure the stability of the upper angle steel 11 and the lower angle steel 12 on the lower flange of the secondary beam, the overlap length between the upper angle steel 11 and the lower flange of the secondary beam shall not be less than 55mm.

[0025] A fixing plate 14 is installed on the vertical edge of the lower angle steel 12. The fixing plate 14 and the lower angle steel 12 are connected by fastening bolts 17 for easy installation and disassembly. A hanging rod 15 is installed on the fixing plate 14. The upper end of the hanging rod 15 has a notch with the same thickness as the fixing plate 14. The notch of the hanging rod 15 matches the fixing plate 14 and is welded together to ensure a tight connection between the hanging rod 15 and the fixing plate 14. The hanging rod 15 is used to connect pipe hangers.

[0026] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
