Description
Technical Field
[0001] This utility model belongs to the technical field of reinforced frame based on the vertical long side of purlin, specifically relating to a reinforced frame based on the vertical long side of purlin. Background Technology
[0002] A reinforcing frame based on the vertical long side of a purlin typically refers to a reinforced structural frame installed along the long side of the purlin perpendicular to its length in a purlin structure. This frame is generally fixed to the purlin body by welding, bolting, or other methods, and is often made of materials such as angle steel, channel steel, or steel plates. Its function is to enhance the purlin's bending and torsional resistance in the direction perpendicular to the span, improving the overall stiffness and stability of the purlin. Especially when subjected to large loads or needing to resist external forces such as wind loads and snow loads, it can effectively reduce purlin deformation and prevent structural safety from being compromised due to local instability. It is commonly used in the reinforcement design of purlin systems for steel structure roofs and walls.
[0003] Photovoltaic modules are mounted with beams, and purlins are located on the back of the module, directly contacting the frame. The beams are perpendicular to the long side of the module, and two beams support one module. Frame modules generally have two mounting methods: fixing with four screw holes along the two long sides, or fixing with four module clamps along the two long sides. The thickness and width of the bottom surface of the frame remain consistent from end to end, without reinforcement at the contact point with the beams. After the module is fixed to the bracket purlins, under prolonged wind or snow pressure, the distance from the screw holes to the edge of the frame is typically only 4.5 to 5 mm, and the bottom surface area for screw hole mounting is only 1.6 to 1.9 mm. The screw hole mounting method suffers from screw torque and beam pressure. The reverse force of the frame makes the screw holes very easy to tear. The frame wall thickness is only 1.6 to 1.9 mm. Under the torque of 16 to 22 NM of M8 bolts, the contact area with the beam is concave downward, keeping the frame under constant stress. The frame holes are also easy to tear. The bottom surface of the frame forms a 90-degree angle with the vertical surface in the height direction of the frame. The chamfer of the chamfer is generally designed to be R0.5 to R1 mm. During the up and down movement of the component, fatigue occurs, and the chamfer is torn at this chamfer position. From the stress analysis of the component, the contact position between the frame and the beam is the stress concentration point of the component. Under a certain super strong force, the component frame is very easy to break at this position. Utility Model Content
[0004] The purpose of this invention is to provide a reinforced frame based on the vertical long side of the purlin, to solve the problem mentioned in the background art where photovoltaic modules are installed with beams, the purlins are on the back of the module and directly contact the frame, the beams are perpendicular to the long side of the module, two beams support one module, and the frame assembly generally has two installation methods: fixed with four screw holes on the two long sides, or fixed with four component pressure blocks on the two long sides. The thickness and width of the bottom surface of the frame are consistent from end to end, and there is no reinforcement at the contact point with the beams. After the module is fixed on the bracket purlin, under long-term gusts of wind or snow pressure, the distance from the screw holes to the edge of the frame is generally only 4.5 to 5 mm, and the bottom surface including the screw holes is only 1.6 to 1.9 mm. Due to the torque of the screws and the reverse force of the beam on the frame, the screw holes are easily torn. The frame wall thickness is only 1.6 to 1.9 mm. Under the torque of 16 to 22 NM of M8 bolts, the contact area with the beam is concave downward, keeping the frame under constant stress. The frame holes are also easily torn. The bottom surface of the frame forms a 90-degree angle with the vertical surface in the height direction of the frame. The chamfer of the chamfer is generally designed to be R0.5 to R1 mm. During the up and down movement of the component, fatigue occurs, and the chamfer is torn at this chamfer position. From the stress analysis of the component, the contact position between the frame and the beam is the stress concentration point of the component. Under a certain super-strong force, the component frame is very easy to break at this position.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a reinforced frame based on the vertical long side of a purlin, comprising a component long side, component short sides installed at the left and right ends of the component long side, thickened support surfaces provided at the left and right sides of the inner end face of the component long side, bolt mounting holes provided at the upper end of the thickened support surfaces, a through groove provided at the inner side of the component long side, connecting rods fixed at the four corners of the inner wall of the through groove, a stainless steel spring fixed at the other end of the connecting rod, and a connecting plate fixed at the other end of the stainless steel spring.
[0006] Preferably, the front end of the thickened support surface is provided with sharp corners at the left and right sides, and the left and right ends of the thickened support surface are provided with small rounded corners.
[0007] Preferably, the upper end of the thickened support surface has a large rounded corner at the rear position.
[0008] Preferably, the long side of the component is installed at the lower inner side of the short side of the component.
[0009] Preferably, the long side and short side of the component are connected by a corner bracket, and the splicing of two long sides and two short sides of the component forms a complete component structure.
[0010] Preferably, the purlin body is installed on the long side of the component at the upper position through bolt mounting holes.
[0011] Preferably, the connecting rod is fixed at the inner wall position of the long side of the component, and the connecting rod is connected to the connecting plate by a stainless steel spring.
[0012] Preferably, stainless steel springs are fixed at the four corners of the connecting plate.
[0013] Compared with the prior art, this utility model provides a reinforced frame based on the vertical long side of the purlin, which has the following beneficial effects: 1. The C-side of the long side frame of a normal component typically extends vertically from the main body of the frame by about 18 to 25 millimeters, with a thickness of about 1.5 to 2 millimeters. The small C-side in the diagram extends outward by about 10 millimeters, with a wall thickness of 1.2 to 1.5 millimeters. Its function is to enhance the lateral bending resistance and longitudinal cross-sectional strength of the frame. After the packaging section cuts at 45 degrees at both ends of the long side, a section of the frame bottom surface about 50 to 80 millimeters in length is left for later use in limiting and fixing after the paper corner protectors are bent. The mounting section presents a non-standard trapezoidal structure that is wider on the inside and narrower on the outside. It is thickened and widened based on the small C-side. Its main features are thickened support surface, mounting holes, small rounded corners, large rounded corners, sharp edges, etc. The total thickness of the thickened support surface is increased to about 3 millimeters to ensure that it is the original The C-side is about twice the size of the original frame. The large rounded corner is the chamfer between the inner side of the frame and the thickened support surface, with a size greater than or equal to R-mm. The small rounded corner is the chamfer transition between the support surface and the small C-side, which facilitates the transmission and extension of force. The sharp corner is used to smooth out the original 90-degree sharp corner to prevent injury to operators during contact. The mounting holes are the same as the original frame, which are 9*14 mm oblong holes. In the third mounting part dimension drawing, L1 width is greater than 80 mm, L2 size is 12 to 15 mm, L3 size is 24 mm to 30 mm, and L4 width is greater than 120 mm. The larger the L1 and L4 sizes, the stronger the bending resistance of the component frame. The larger the L2 and L3 sizes, the lower the risk of the screw holes being torn after installation.
[0014] 2. The inner groove reinforcing ribs are designed as four connecting rods to fix stainless steel springs, and the springs are connected to the middle connecting plate. The stainless steel springs have elastic deformation capabilities, which can effectively buffer and absorb the energy generated by the structure under load, avoiding stress concentration and damage to the frame. The four connecting rods are reasonably arranged, which can work with the springs to evenly distribute the load to the frame and purlins, enhancing local stiffness and overall stability. The flexible connection of the springs allows the structure to adapt to displacement through its own deformation under conditions such as temperature changes and uneven foundation settlement, reducing additional stress. At the same time, the combination of springs, connecting plates, and connecting rods provides elastic support and limit for the frame, improving adaptability and durability under complex working conditions. It is especially suitable for scenarios that require vibration reduction and deformation adaptation, contributing to structural safety and performance optimization. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. The utility model provides, for example Figure 1-5 The illustrated reinforced frame based on the vertical long side of the purlin includes a component long side 1, component short sides 2 installed at the left and right ends of the component long side 1, thickened support surfaces 3 provided at the left and right ends of the inner end face of the component long side 1, bolt mounting holes 7 provided at the upper end of the thickened support surfaces 3, a through groove 8 provided at the inner side of the component long side 1, connecting rods 9 fixed at the four corners of the inner wall of the through groove 8, a stainless steel spring 10 fixed at the other end of the connecting rod 9, and a connecting plate 11 fixed at the other end of the stainless steel spring 10.
[0024] The small C-face in the diagram extends outward by about 10 millimeters, with a wall thickness of 1.2 to 1.5 millimeters. Its function is to enhance the lateral bending resistance and longitudinal cross-sectional strength of the frame. After the packaging section is cut at a 45-degree angle at both ends of the long side, a section of the frame bottom surface with a length of about 50 to 80 millimeters is left for later use to limit and fix the paper corner protectors after bending. The installation section presents a non-standard trapezoidal structure that is wider on the inside and narrower on the outside. It is thickened and widened based on the small C-face. Its main features are the thickened support surface 3, mounting holes, small rounded corners 6, large rounded corners 5, and sharp edges 4. The total thickness of the thickened support surface 3 is increased to about 3 millimeters, ensuring that it is about twice the thickness of the original C-face. The large rounded corner 5 is the chamfered angle between the inner vertical surface of the frame and the thickened support surface 3. The small rounded corner 6 is the chamfered transition between the support surface and the small C-face to facilitate the transmission and extension of force. The sharp edges 4 are used to remove the sharp edges of the original 90-degree angle to prevent personnel from being injured during contact.
[0025] like Figure 2 and Figure 4As shown, the front end of the thickened support surface 3 has sharp corners 4 at the left and right sides, and small rounded corners 6 at the left and right ends of the thickened support surface 3. The upper end of the thickened support surface 3 has a large rounded corner 5 at the rear position. The long side 1 of the component is installed at the lower inner side of the short side 2 of the component. The long side 1 of the component and the short side 2 of the component are connected by corner brackets. The splicing of the two long sides 1 of the component and the two short sides 2 of the component forms a complete component structure. The purlin body 12 is installed at the upper position of the long side 1 of the component through the bolt mounting hole 7. The connecting rod 9 is fixed at the inner wall of the long side 1 of the component. The connecting rod 9 is connected to the connecting plate 11 through the stainless steel spring 10. The stainless steel spring 10 is fixed at the four corners of the connecting plate 11.
[0026] The four connecting rods 9 are arranged in a reasonable manner, which can work with the springs to evenly distribute the load to the frame and purlins, enhance local stiffness and overall stability. The flexible connection of the springs allows the structure to adapt to displacement through its own deformation under conditions such as temperature changes and uneven foundation settlement, thereby reducing additional stress. At the same time, the combination of the springs, connecting plates 11, and connecting rods 9 provides elastic support and limit for the frame, improving adaptability and durability under complex working conditions.
