Description

Technical Field

[0001] This utility model relates to the field of building technology, and in particular to an anti-disengagement anchoring connection device for large-span metal roof structures. Background Technology

[0002] With the widespread use of standing seam metal roofing systems in large-span public buildings, many instances of wind uplift damage have emerged. The wind uplift resistance of standing seam metal roofing systems has become a primary consideration in the use and promotion of this structure. Despite this, standing seam roofs in large-span structures still suffer large-area wind uplift and disengagement damage caused by strong winds within the allowable design wind load range.

[0003] A standing seam metal roofing system mainly consists of profiled metal roofing panels, a functional layer (insulation and waterproofing layer), fixed supports, and a support system, all connected by corresponding fasteners. Damage to a standing seam metal roofing system often occurs when the roof panel separates from the fixed supports at the seams, i.e., a disengagement failure. The connection between the supports and purlins remains largely intact. Disengagement failure will cause a section of the roof panel to be lifted, ultimately leading to the overall failure of the metal roofing system. This is because, over long-term service, the insulation and waterproofing materials in the functional layer of the standing seam metal roofing system will age or become damaged, resulting in gaps between the metal roofing panels and the support system. Prolonged service with these gaps can easily lead to abnormal vibrations in the metal roof, causing the fasteners to loosen or even disengage. Utility Model Content

[0004] Other features and advantages of this invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of this invention may be realized and obtained by means of the structures particularly pointed out in the description and other accompanying drawings.

[0005] The purpose of this utility model is to overcome the above-mentioned shortcomings and provide an anti-disengagement anchoring connection device for large-span metal roof structures to solve the existing problems.

[0006] To achieve the above objectives, the technical solution of this utility model is: a large-span metal roof anti-disengagement anchoring connection device, comprising a bottom support, on which a suspended top layer and a dustproof layer are installed sequentially from bottom to top. Multiple main purlins with equal spacing are horizontally installed on the top of the dustproof layer, with sound-absorbing cotton filled between them, thus covering the entire dustproof layer in a flat plane. Multiple secondary purlins with equal spacing are vertically installed on the top of the main purlins, and T-shaped fixing supports with equal spacing are installed on the top of each secondary purlin. After installing the T-shaped fixing supports, a metal mesh is laid on top, and then... The non-woven fabric, the metal mesh, and the non-woven fabric have openings corresponding to the T-shaped fixing bracket for passage. A support plate is laid on the non-woven fabric, and the end face of the support plate has a through groove corresponding to the fixing bracket. The vertical panel of the T-shaped fixing bracket has an installation groove, and an expansion joint is installed in the installation groove. The support plate passes through the installation groove through a connecting plate, so that the connecting plate is located on top of the expansion joint. Then, the two sides are fixed to the end face of the support plate with bolts. An insulation layer and a waterproof layer are installed on the top of the support plate from bottom to top. A metal roof is installed on top of the waterproof layer, and the metal roof is locked to the top of the T-shaped fixing bracket.

[0007] In some embodiments, the telescopic member includes a base with a placement groove on its end face, a connecting seat on the top of the base, a spring in the placement groove, a sliding plate on the top of the spring, the sliding plate being slidably connected to the placement groove, and a connecting rod in the middle of the connecting seat being connected to the sliding plate.

[0008] In some embodiments, the through groove is provided on both sides with fixing grooves that match the shape and size of the connecting plate.

[0009] In some embodiments, the connector has a threaded hole on its top, and is connected to the connector by bolts passing through the connector plate.

[0010] In some embodiments, the top two sides of the T-shaped fixed support are provided with locking grooves, and the locking grooves are provided with a plurality of sharp protrusions.

[0011] In some embodiments, the metal roof seam is provided with a plurality of surface-mounted clamps.

[0012] In some embodiments, each row of the clamps is connected in series by steel ropes.

[0013] By adopting the above technical solution, the beneficial effects of this utility model are:

[0014] 1. The expansion joints lift the support plate, allowing the metal roof, insulation layer, and waterproof layer to tighten. This prevents gaps caused by aging, extends its service life, and prevents vibration. The matching connecting plate passing through the matching mounting groove also provides a limiting effect, preventing the support plate from shaking. At the same time, the metal mesh covering the bottom of the T-shaped fixing bracket increases stability, and the non-woven fabric provides excellent waterproofing and delays rusting at the joints.

[0015] 2. By setting grooves and sharp protrusions on the lock edge support, the folded part at the root of the lock edge can be better embedded, thereby ensuring the tightness of the outer lock edge and the lock head. This design can also effectively prevent the loosening of the outer lock edge and the lock edge support, and enhance the tightness of the connection of the metal roof standing lock edge structure.

[0016] 3. Connect the clamps together with steel ropes to ensure that the spacing between the clamps allows for quick installation. At the same time, connecting the steel ropes together can connect the entire roof system into a whole, enhancing the overall stability of the roof under strong winds.

[0041] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0042] Reference Figure 1-4This utility model provides an anti-disengagement anchoring connection device for a large-span metal roof structure, including a bottom support 1. A suspended ceiling 11 and a dustproof layer 12 are installed sequentially from bottom to top on the bottom support 1. Multiple main purlins 13 with equal spacing are horizontally installed on the top of the dustproof layer 12, with sound-absorbing cotton 19 filling the spaces between them, thus covering the entire dustproof layer 12 in a flat plane. Multiple secondary purlins 14 with equal spacing are vertically installed on the top of the main purlins 13. T-shaped fixing supports 2 with equal spacing are installed on the top of each secondary purlin 14. After installing the T-shaped fixing supports 2, a metal mesh 15 is laid on top, and a non-woven fabric 16 is laid on top of the metal mesh 15. The metal mesh 15 and the... The non-woven fabric 16 has an opening corresponding to the T-shaped fixed support 2 for passage. A support plate 21 is laid on the non-woven fabric 16. The end face of the support plate 21 has a through groove 22 corresponding to the fixed support 2. The vertical panel in the T-shaped fixed support 2 has an installation groove 23. An expansion joint 3 is provided in the installation groove 23. The support plate 21 passes through the installation groove 23 through a connecting plate 24, so that the connecting plate 24 is located on top of the expansion joint 3. Then, the two sides are fixed to the end face of the support plate 21 with bolts. An insulation layer 18 and a waterproof layer 17 are installed on the top of the support plate 21 from bottom to top. A metal roof 5 is installed on the top of the waterproof layer 17. The metal roof 5 is locked to the top of the T-shaped fixed support 2.

[0043] The process involves sequentially installing the ceiling layer 11 and dustproof layer 12 onto the bottom support 1, followed by installing the secondary purlins 14 onto the main purlins 13. It's important to note that the horizontal and vertical installations are based on actual conditions. Next, sound-absorbing cotton 19 is installed, forming a plane with the main purlins 13. After installing the secondary purlins 14, T-shaped fixing supports 2 are bolted onto them. Then, metal mesh 15 and non-woven fabric 16 are sequentially placed, with the top of the T-shaped fixing support 2 passing through the metal mesh 15 and non-woven fabric 16 to fix it to the secondary purlins 14. Finally, the support plate 21 is installed, allowing the top of the T-shaped fixing support 2 to pass through the corresponding through-slot 22, and then connected with a connecting plate 24. This allows the connecting plate 24 to move the support plate 21 upwards. The top of the support plate 21 is covered with an insulation layer 18 and a waterproof layer 17. The top is then fixed by a metal roof 5. During long-term use, the insulation and waterproof materials will age or be damaged. The expansion joint 3 is used to lift the support plate 21, which tightens the metal roof 5, insulation layer 18 and waterproof layer 17. This prevents gaps caused by aging, extends its service life, and prevents vibration. The matching connecting plate 24 passes through the matching mounting groove 23 and can also limit the movement of the support plate 21. At the same time, the metal mesh 15 covers the bottom of the T-shaped fixing support 2 to increase the stability. The non-woven fabric 16 can effectively waterproof the area and delay rusting at the joint. Only the top of the T-shaped fixing support 2 needs to be exposed.

[0044] According to some embodiments of this utility model, optionally, the telescopic member 3 includes a base 31, with a placement groove 32 on the end face of the base 31, and a connecting seat 33 fitted on the top of the base 31. A spring 34 is provided in the placement groove 32, and a sliding plate 35 is provided on the top of the spring 34. The sliding plate 35 is slidably connected to the placement groove 32. A connecting rod 36 is provided in the middle of the connecting seat 33, and the connecting rod 36 is connected to the sliding plate 35. The spring 34 drives the sliding plate 35 upward, which in turn drives the connecting seat 33 to lift the support plate 21, thereby achieving the tightening function. At the same time, the sliding plate 35 is slidably connected to the placement groove 32 to increase the connectivity of the connecting seat 33.

[0045] According to some embodiments of this utility model, optionally, the through groove 22 is provided with fixing grooves 25 on both sides that match the shape and size of the connecting plate 24. In this way, when installing the connecting plate 24, the connecting plate 24 can be embedded in the support plate 21 without its surface protruding, so that the support plate 21 can fit well against the bottom of the insulation layer 18.

[0046] According to some embodiments of this utility model, optionally, the top of the connecting seat 33 is provided with a threaded hole 37, and a bolt is passed through the connecting plate 24 to connect the connecting seat 33. This can ensure the connectivity between the connecting plate 24 and the connecting seat 33, and can achieve a more stable connection.

[0047] According to some embodiments of this utility model, optionally, the T-shaped fixed support 2 has locking grooves 26 on both sides of its top, and the locking grooves 26 have multiple sharp protrusions 27. By providing grooves and sharp protrusions 27 on the locking support, the folded part at the root of the locking edge can be better embedded, thereby ensuring the tightness of the engagement between the outer locking edge and the lock head. This design can also effectively prevent the loosening of the outer locking edge and the locking support, and enhance the tightness of the connection of the standing seam structure of the metal roof.

[0048] According to some embodiments of this utility model, optionally, the metal roof 5 has multiple clamps 4 mounted on its surface at the seam edge. The clamps 4 can increase the connectivity of the metal roof 5, and can also be used to install brackets on top and then install a decorative layer to increase the decorativeness of the top.

[0049] According to some embodiments of this utility model, optionally, each row of clamps 4 is connected in series by steel ropes 41. Connecting the clamps 4 in series with steel ropes 41 ensures that the spacing between the clamps 4 allows for quick installation, and at the same time, connecting the steel ropes 41 in series can connect the entire roof system into a whole, enhancing the overall stability of the roof under strong winds.

[0050] Working principle:

[0051] The installed T-shaped fixed support 2 is connected to the metal roof 5 by locking the top, and then the expansion joint 3 is set on the support to be connected to the support plate 21. This can tightly fit the insulation layer 18 to the bottom of the metal roof 5 to prevent gaps from forming and causing it to sway in strong winds. The T-shaped fixed support 2 will then shake and come off.
