Description

Technical Field

[0001] This invention belongs to the field of roof panel connection and reinforcement technology, specifically relating to a convenient roof panel connection node. Background Technology

[0002] Metal roofing is a building envelope structure where the roof panel forms an angle of less than 75° with the horizontal direction and does not share the loads of the main building structure. It mainly consists of an upper metal panel and a lower support system. Metal roofing first appeared in European architecture and has a history of nearly 90 years, finding widespread application in various types of buildings abroad. my country began introducing metal roofing in the 1980s, leading to its rapid development and application domestically. However, with the continuous application of metal roofing, its problems have also become increasingly apparent, causing significant losses to national economic development and the safety of life and property.

[0003] Metal roofs, as lightweight building envelope systems, are highly sensitive to wind loads, especially under strong winds. The powerful suction and pulsating effects caused by wind loads often lead to the failure of connections between components, potentially causing them to be lifted or blown off in strong winds. For example, the roof of Terminal 3 at Beijing Capital International Airport was designed to withstand a once-in-a-century storm, but it was torn off three times in four years. The standing seam of the main terminal building at Wuhan Tianhe International Airport Phase II was also damaged by strong winds; subsequent inspections revealed that the damage was caused by insufficient negative wind pressure bearing capacity at the seam, leading to its detachment.

[0004] Metal roofing systems can be categorized by their connection method into two types: Overlapping roofing systems, characterized by panels naturally overlapping and then being connected to the structure via fasteners. Overlapping systems can be further divided into high-wave and low-wave connections. Low-wave connections involve directly connecting the roof panels to purlins or main structural joists using self-tapping screws. High-wave connections utilize special brackets, where the roof panels are riveted to the brackets with self-tapping screws, and then the brackets are connected to the structural purlins or joists using self-tapping screws. The advantages of this overlapping method are convenience, speed, and strong load-bearing capacity. The disadvantage is that the roof panels have holes, which may lead to roof leaks.

[0005] The snap-fit ​​roofing system is a concealed connection method. During roof panel installation, the panels are joined together by snap-fit ​​and connected to the structure using concealed fastener brackets. At the crests of the roof panels, clips are used to secure them, forming a mechanical connection.

[0006] Interlocking roofing systems involve naturally overlapping the longitudinal edges of pre-formed panels, then using specialized machinery to roll and interlock the edges along the length, and finally connecting them to the main structure using fixed brackets. Bracket-interlocking connections typically involve locking aluminum-magnesium-manganese or aluminum-zinc alloy roof panels to upright high-strength aluminum alloy brackets. Because it's a concealed roofing system, it offers good waterproofing. The fixed brackets allow for longitudinal expansion and contraction of the panels, effectively mitigating the effects of temperature stress. Its disadvantages are: firstly, because the roof panels are "suspended" above the purlins, they cannot provide lateral stability to the purlins, requiring additional supports to form a complete structural system; secondly, the mechanical interlocking method between the side seams of the roof panels can easily damage the coating. Continuous welded stainless steel roofing systems involve welding pre-formed and interlocked stainless steel roof panels using specialized fully automated welding equipment, with the welds located on the vertical edges of the panels. This effectively solves problems such as roof leaks and panel lift-off due to wind. However, significant temperature stress is generated during the welding process. Summary of the Invention

[0007] To overcome the shortcomings of existing technologies, this invention provides a convenient roof panel connection node that can improve the deficiencies of traditional roof panels, such as insufficient wind load-bearing capacity, while also taking into account factors such as temperature stress relief and waterproofing. While meeting various requirements, it also facilitates installation, speeds up construction, and reduces unnecessary human factors.

[0008] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0009] A convenient roof panel connection node is characterized by: including a support, the support being an I-shaped structure, the bottom of which is connected to a purlin; the support is rotatably connected to two clamping plates on both sides, and the top of the clamping plates on both sides forms an inverted trapezoidal cavity;

[0010] The top of the support is threaded with a bolt, and a wedge is provided on the bolt. The wedge has an inverted trapezoidal structure.

[0011] A roof panel is provided between the bottom of the clamping plate and the supporting column in the middle of the support.

[0012] The wedge's shape matches the inverted trapezoidal cavity formed at the top of the clamping plate. As the wedge moves downward, it causes the clamping plate to rotate inward, thereby clamping the roof panel.

[0013] Furthermore, the support and the clamping plate are connected by a hinge, and a pivot is provided at the hinge position.

[0014] Furthermore, a spring is provided between the top surface of the wedge and the bolt.

[0015] Furthermore, the support column in the middle of the support is provided with support concave surfaces on both sides, and the clamp plate is provided with clamp plate protrusions corresponding to the support concave surfaces.

[0016] Furthermore, the support column in the middle of the support has circular gaps on both sides at the top of the support.

[0017] Furthermore, the top of the supporting column in the middle of the support is provided with an upper groove, and a type I cover plate is provided at the position of the upper groove; the type I cover plate is inverted U-shaped and covers the roof panels on both sides.

[0018] Furthermore, a Type II cover plate is provided above the bolt, and the Type II cover plate has an inverted trapezoidal structure.

[0019] The beneficial effects of this invention are:

[0020] 1) This invention does not damage the panel layer and does not require drilling holes in the roof panel, thus enabling the installation of the roof panel;

[0021] 2) The support of the present invention has a concave surface and a gap in the middle, which can improve the wind resistance of the roof panel;

[0022] 3) This invention connects the roof panels using clamps, wedges, pivots, supports, and studs. It is easy to operate and convenient to install, and the installation method is simple, which can prevent roof panel quality problems caused by the worker's skill level. Attached Figure Description

Detailed Implementation

[0030] The present invention will now be described in detail with reference to specific embodiments.

[0031] This invention achieves the up-and-down movement of the bolts by rotating the three upper bolts. During the up-and-down movement of the bolts, the wedges will move. The wedges are narrow at the bottom and wide at the top. When the wedges move downward, they will cause the clamping plate to rotate around the pivot, thereby achieving the effect of clamping the roof panel. In use, when the roof panel is subjected to a load perpendicular to the roof panel, the clamping plate will rotate. Since the wedges cannot move up and down, the clamping plate is prevented from rotating.

[0032] like Figure 1 , 2 As shown in Figures 6 and 7, the present invention includes a support 4, which has an I-shaped structure and is connected to the purlin at the bottom. Clamping plates 2 are rotatably connected to both sides of the support 4. The top of the clamping plates 2 forms an inverted trapezoidal cavity, and the upper surface of the clamping plates is inclined. The support 4 and the clamping plates 2 are connected by hinges, and a pivot 5 is provided at the hinge position. A schematic diagram of the pivot 5 is shown below. Figure 4 As shown;

[0033] The top of the support 4 is threaded with three bolts 1, which are arranged at equal intervals. Each bolt 1 has a wedge 3, which is an inverted trapezoidal structure.

[0034] A roof panel 9 is installed between the bottom of the clamping plate 2 and the supporting column in the middle of the support 4;

[0035] The wedge 3 has the same shape as the inverted trapezoidal cavity formed at the top of the clamping plate 2. As the wedge 3 moves downward, it will cause the clamping plate 2 to rotate inward, thereby clamping the roof panel 9.

[0036] A spring 8 is provided between the top surface of the wedge 3 and the bolt 1. The spring is provided between the wedge and the bolt to prevent material creep.

[0037] The support column in the middle of the support 4 has concave surfaces a on both sides, and the clamp plate 2 has protrusions b on the clamp plate corresponding to the concave surfaces a. The support column in the middle of the support 4 has circular gaps c on the upper part of the support. When subjected to an inward load from the vertical roof panel, the concave surfaces on both sides of the middle of the support 4 will increase the friction distance, and the circular gap between the support and the upper part of the clamp plate will serve as a tie.

[0038] A type II cover plate 7 is provided above bolt 1. The type II cover plate 7 has an inverted trapezoidal structure, such as... Figure 5As shown;

[0039] The top of the supporting column in the middle of the support 4 is provided with an upper groove d, and a type I cover plate 6 is set at the position of the upper groove d of the support. The type I cover plate 6 is inverted U-shaped and covers the roof panels 9 on both sides. The cover plate is inserted into the groove and between the clamping plate to prevent rainwater from entering the room through the gap between the roof panels in the middle of the two supports, thus playing a waterproof role.

[0040] The installation method of this invention is as follows:

[0041] The first step is to place the support 4 on the purlin and connect it by welding or bolting.

[0042] The second step is to unscrew the three bolts on the top upwards. At this point, the wedge 3 can move up and down, and the clamp 2 can rotate left and right.

[0043] The third step is to roll the end of the roof panel into a circle and insert it into the circular gap. Then, place the two roof panels between the support 4 and the clamping plate 2.

[0044] Fourth step, insert the cover plate into the support through the d groove, and ensure that the cover plate covers the roof panels on both sides;

[0045] Fifth step, install the spring and insert the bolts into the wedges until they pass through the support bolt holes. Tighten the top three bolts to move them downwards until they are tightened.

[0046] Step 6: Install the Type II cover plate by placing the cover plate onto the clamp and using tools to engage them together.
