Description

Technical Field

[0001] This utility model belongs to the field of metal roofing connection technology, specifically relating to a floating and fixing connection device between stainless steel panels and aluminum keel. Background Technology

[0002] Stainless steel panels are widely used in metal roofing. Stainless steel has high strength, durability, and excellent corrosion resistance. The panels are not easily deformed or damaged, which greatly extends the service life of metal roofing. Stainless steel panels have a unique metallic luster and texture, a simple and smooth appearance, and strong lines, which can add a modern and industrial aesthetic to buildings. Moreover, this aesthetic effect is durable and will not fade or change color over time, always maintaining a new look.

[0003] Problems with existing technology:

[0004] Conventional metal roof panels are directly fixed to roof purlins or joists using self-tapping screws or rivets. However, metal roof panels expand and contract with temperature changes, and nail fixing restricts the free expansion and contraction of the roof panels, which may lead to stress concentration, deformation, or even cracking of the roof panels, affecting the normal use and durability of the roof system. Therefore, it is not recommended to use direct nailing for installation. Utility Model Content

[0005] The purpose of this invention is to provide a floating and fixed connection device between a stainless steel panel and an aluminum keel, which can expand and contract when the panel frame deforms, thus avoiding the deformation of the stainless steel panel under large temperature differences and preventing damage to the connecting parts, thereby increasing structural safety.

[0006] The specific technical solution adopted by this utility model is as follows:

[0007] A floating fixing connection device for stainless steel panel and aluminum keel, including aluminum alloy keel and keel, wherein the aluminum alloy keel is connected to two keels by a pressing connector or a floating connector;

[0008] The pressure-holding connector includes an aluminum alloy keel whose top center is fixed to a T-shaped pressure plate by bolts. The T-shaped pressure plate is composed of a vertical block and a first horizontal plate. The bottom center of the first horizontal plate is integrally provided with a first vertical block. The outer wall of the first horizontal plate and the two sides of the first vertical block form two outward-facing first sliding grooves with the top of the aluminum alloy keel. The outer walls of the two keels are fixed with first T-shaped connectors that cooperate with the first sliding grooves by screws. The first T-shaped connector is composed of a second vertical plate and a second horizontal plate. The top center of the second horizontal plate is integrally provided with the second vertical plate. One side of the second horizontal plate extends into the first sliding groove.

[0009] The bottom side of the second horizontal plate is provided with a first mounting groove, and the interior of the first mounting groove is provided with a first pad that slides in contact with the top of the aluminum alloy keel.

[0010] The bottom sides of the first horizontal plate are provided with second protrusions, and the top edge of the second horizontal plate is fixed with a first protrusion located in the first sliding groove, which is used to limit the movement of the first T-shaped connector.

[0011] The floating connector includes a second T-shaped connector disposed on the top of the aluminum alloy keel and connected to one of the keel screws. The second T-shaped connector is composed of a third vertical plate and a third horizontal plate. The top of the third horizontal plate is integrally disposed with the third vertical plate. A limiting plate is fixed on one side of the third vertical plate. The bottom of the limiting plate and the top of the third horizontal plate cooperate with the third vertical plate to form a second sliding groove. A first L-shaped connector is disposed on the top of the aluminum alloy keel and on one side of the second T-shaped connector and fixed to the keel screw. A fixing plate inserted into the second sliding groove is fixed on one side of the first L-shaped connector.

[0012] Two second mounting slots are provided on one side of the fixing plate within the second sliding groove, and a second pad block that mates with the inner wall of the second sliding groove is provided inside the second mounting slot.

[0013] The technical effects achieved by this utility model are as follows:

[0014] This utility model uses a pressure block for fixing, and the panel frame can expand and contract when deformed, which avoids damage to the connecting parts under large temperature differences and increases structural safety.

[0015] In this invention, at the joints where nails cannot be used for fixing, the connectors are fixed by one part nailing and the other part inserting, which can meet the effect requirements of different joint widths.

[0016] This utility model adopts a floating fixed connection method, which not only solves the problem of panel expansion and contraction caused by temperature deformation, but also meets the needs of more different effects, resulting in better overall effect and appearance, and improving aesthetics.

[0026] The pressure-holding connector 3 includes a T-shaped pressure plate 34 fixed to the top center of the aluminum alloy keel 1 by bolts. The T-shaped pressure plate 34 is composed of a vertical block and a first horizontal plate. The bottom center of the first horizontal plate is integrally provided with a first vertical block. The outer wall of the first horizontal plate and the two sides of the first vertical block form two outward-facing first sliding grooves 37 with the top of the aluminum alloy keel 1. The outer walls of the two stainless steel frames 2 are fixed with first T-shaped connectors 31 that cooperate with the first sliding grooves 37 by screws. The first T-shaped connector 31 is composed of a second vertical plate and a second horizontal plate.

The second T-shaped connector 45 is composed of a third vertical plate and a third horizontal plate. The top of the third horizontal plate is integrally disposed with the third vertical plate. A limiting plate 46 is fixed on one side of the third vertical plate. The bottom of the limiting plate 46 and the top of the third horizontal plate cooperate with the third vertical plate to form a second sliding groove 47. A first L-shaped connector 41 is disposed on the top of the aluminum alloy keel 1 and on one side of the second T-shaped connector 45 and screwed to the keel 2. A fixing plate 42 inserted into the second sliding groove 47 is fixed on one side of the first L-shaped connector 41. Two second mounting grooves 43 are disposed on one side of the fixing plate 42 in the second sliding groove 47. A second pad 44 that cooperates with the inner wall of the second sliding groove 47 is disposed inside the second mounting groove 43.

[0030] According to the above structure, the second T-shaped connector 45 is connected to one of the stainless steel frames 2 by screws and fixed to the top of the aluminum alloy keel 1.
