Description

Technical Field

[0001] This utility model belongs to the field of greenhouse building structure technology, specifically relating to wind-resistant steel structures for greenhouses. Background Technology

[0002] A utility model patent with patent authorization announcement number CN204443371U discloses a greenhouse frame, including an upper chord beam, a lower chord beam, a retaining spring, Z-shaped support ribs, and a chord beam fixing component. The chord beam fixing component of the greenhouse frame is fixedly connected to the lower chord beam by bolts and fixing holes. The chord beam fixing component is located below the upper chord beam and above the lower chord beam. The chord beam fixing component is perpendicular to the upper chord beam, the lower chord beam, and the Z-shaped support ribs that are simultaneously connected to the upper chord beam and the lower chord beam. The chord beam fixing component is fixed relative to the upper chord beam by two Z-shaped support ribs.

[0003] Currently, multi-span greenhouses are widely used in modern agricultural production, with the spacing between their transverse main steel frames typically around 5000mm. In practical use, the end walls need to withstand large-area wind loads, necessitating larger cross-sections for the end wall purlins to meet strength and stability requirements. Larger purlin cross-sections not only increase steel consumption and construction costs but also block sunlight, reducing the amount of light entering the greenhouse and negatively impacting crop growth.

[0004] To address the aforementioned issues, this application proposes a wind-resistant steel structure for greenhouses. Summary of the Invention

[0005] The purpose of this invention is to provide a wind-resistant steel structure for greenhouses. It solves the problem that in practical use, the end walls need to withstand large areas of wind load, which necessitates that the end wall purlins have large cross-sections to meet strength and stability requirements. Larger end wall purlin cross-sections not only increase the amount of steel used, leading to higher construction costs, but also block some sunlight, resulting in poor lighting in the greenhouse.

[0006] To achieve the above objectives, this utility model provides a wind-resistant steel structure for greenhouses, including a greenhouse foundation. A main steel frame column is bolted to the upper end of the greenhouse foundation, and a main steel frame beam is bolted to the back of the main steel frame column. End wall purlins are welded or bolted to the front of the main steel frame column. A wind-resistant column is bolted to the upper end of the greenhouse foundation, and the wind-resistant column is welded or bolted to the end wall purlins. A horizontal pressure beam is welded or bolted to the back of the wind-resistant column, and diagonal horizontal tie rods are welded or bolted to the horizontal pressure beam.

[0007] The principle of this utility model is as follows: wind-resistant columns are added between the main steel frame columns of the multi-span greenhouse, and the bottom of the wind-resistant columns is reliably connected to the greenhouse foundation and other components to ensure that the wind-resistant steel structure of the greenhouse has a stable supporting foundation. A horizontal pressure beam is set at the top of the wind-resistant column along the direction of force. Under the action of the horizontal pressure beam, the wind load can be effectively transferred and dispersed, enhancing the stability of the entire wind-resistant system. Diagonal horizontal tie rods are set on both sides of the wind-resistant column, with one end of the diagonal horizontal tie rod connected to the top of the main steel frame column and the other end connected to the end of the horizontal pressure beam to form a stable triangular structure. The wind load is transferred to the main steel frame column and main steel frame beam through the wind-resistant column and the diagonal horizontal tie rod, thereby reducing the wind load borne by the end wall purlins.

[0008] When the wind-resistant column is installed with bolts to the greenhouse foundation, the welded reinforcing ribs can be brought into contact with the greenhouse foundation. Then, the push end drives the screw and the extrusion head through the reinforcing ribs, bringing the screw into contact with the greenhouse foundation. The push end then drives the screw to rotate, causing the screw to make threaded motion, thus installing the screw. When the screw drives the extrusion head to rotate and advance, when the extrusion head contacts the inclined end of the clamping plate, the extrusion head can push the end plate to move, causing the spring to deform. Finally, the clamping plate comes into contact with the screw surface. Under the action of force, the clamping plate slides along the screw surface. When the clamping plate slides into the slot, the spring returns to its original deformation, pulling the clamping plate into the slot for end-connection. This limits the screw and prevents the screw from vibrating and loosening.

[0009] The beneficial effects of this utility model are as follows: This solution enhances the overall structural stability by using a combination of wind-resistant columns, horizontal pressure beams, and diagonal horizontal tie rods, effectively improving the wind resistance of the end walls of the multi-span greenhouse, ensuring the safe use of the greenhouse under severe weather conditions, and allowing for a reduction in the cross-section of the end wall purlins, significantly reducing the amount of steel used and directly lowering the construction cost of the multi-span greenhouse. Furthermore, the smaller end wall purlin cross-section reduces sunlight obstruction, increasing the amount of light entering the greenhouse and providing more ample light for the growth of crops, which is beneficial for improving crop yield and quality. The end caps and screws allow for locking the reinforcing ribs, providing auxiliary reinforcement to the wind-resistant columns. The slots and plates allow for limiting the end caps, preventing vibration, deflection, and loosening of the screws, thus ensuring the long-term stability of the wind-resistant column installation.

[0010] Furthermore, multiple wind-resistant columns are provided, and these columns are evenly distributed on the greenhouse foundation. The installation of these wind-resistant columns ensures that the wind-resistant steel structure of the greenhouse has a stable supporting foundation.

[0011] Furthermore, the other end of the inclined horizontal tie rod is welded or bolted with a turnbuckle, and the other end of the turnbuckle is bolted to the main steel frame column. By setting the inclined horizontal tie rod, a stable triangular structure can be formed, thereby reducing the wind load borne by the end wall purlin.

[0012] Furthermore, the wind-resistant column is equipped with a reinforcement mechanism, which includes a reinforcement rib. A reinforcement rib is welded to the left end of the wind-resistant column. The horizontal part of the reinforcement rib contacts the greenhouse foundation. An end is movably connected to the horizontal part of the reinforcement rib. A screw is fixedly connected to the lower end of the end. The screw is connected to the greenhouse foundation by bolts. A slot is formed on the surface of the end. A locking plate is slidably connected to the horizontal part of the reinforcement rib. The locking plate is slidably connected to the reinforcement rib and the slot. An end piece is fixedly connected to the left end of the locking plate. The end piece contacts the reinforcement rib and is slidably connected to the greenhouse foundation. Through the setting of the screw and the end, the reinforcement rib can be locked to improve the stability of the wind-resistant column. The slot, locking plate and other structures can limit the end, avoiding the problem of the screw loosening due to vibration.

[0013] Furthermore, a compression head is fixedly connected to the lower end of the screw. The compression head contacts the greenhouse foundation. By setting the compression head, the inclined end of the card plate can be compressed.

[0014] Furthermore, multiple card slots are provided, and the multiple card slots are arranged in a circular array on the end. The design of the card slots facilitates the insertion and use with the card plate.

[0015] Furthermore, a spring is welded to the right end of the end piece, and the other end of the spring is welded to a reinforcing rib. The end piece can be connected and used by means of the spring. Attached Figure Description

Detailed Implementation

[0023] The implementation examples are basically as follows Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, this embodiment provides a wind-resistant steel structure for a greenhouse, including a greenhouse foundation 1. A main steel frame column 2 is bolted to the upper end of the greenhouse foundation 1. A main steel frame beam 3 is bolted to the back of the main steel frame column 2. An end wall purlin 4 is welded to the front of the main steel frame column 2. A wind-resistant column 5 is bolted to the upper end of the greenhouse foundation 1. The wind-resistant column 5 is welded or bolted to the end wall purlin 4. A horizontal pressure beam 6 is welded or bolted to the back of the wind-resistant column 5. An oblique horizontal tie rod 7 is welded or bolted to the horizontal pressure beam 6.

[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, multiple wind-resistant columns 5 are set up, and the multiple wind-resistant columns 5 are evenly distributed on the greenhouse foundation 1. By setting up the wind-resistant columns 5, the wind-resistant steel structure of the greenhouse can be ensured to have a stable supporting foundation. The other end of the diagonal horizontal tie rod 7 is welded or bolted to a turnbuckle. The other end of the turnbuckle is bolted to the main steel frame column 2. By setting up the diagonal horizontal tie rod 7, a stable triangular structure can be formed, thereby reducing the wind load borne by the end wall purlin 4.

[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5As shown, a reinforcing mechanism 8 is provided on the wind-resistant column 5. The reinforcing mechanism 8 includes a reinforcing rib 81. The reinforcing rib 81 is welded to the left end of the wind-resistant column 5. The horizontal part of the reinforcing rib 81 contacts the greenhouse foundation 1. An end 82 is movably connected to the horizontal part of the reinforcing rib 81. A screw 83 is fixedly connected to the lower end of the end 82. The screw 83 is connected to the greenhouse foundation 1 by bolts. A slot 85 is opened on the surface of the end 82. A locking plate 86 is slidably connected to the horizontal part of the reinforcing rib 81. The plate 86 is slidably connected to the reinforcing rib 81, and the card plate 86 is slidably connected to the card slot 85. The left end of the card plate 86 is fixedly connected to the end piece 87, which contacts the reinforcing rib 81 and is slidably connected to the greenhouse foundation 1. The reinforcing rib 81 can be locked by the screw 83 and the end 82 to improve the stability of the wind-resistant column 5. The end 82 can be limited by the card slot 85, card plate 86 and other structures to prevent the screw 83 from loosening due to vibration.

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, a pressing head 84 is fixedly connected to the lower end of the screw 83. The pressing head 84 contacts the greenhouse foundation 1. The pressing head 84 can be used to press the inclined end of the card plate 86. Multiple card slots 85 are provided. The multiple card slots 85 are arranged in a ring array on the end 82. The card slots 85 facilitate the insertion and use with the card plate 86. A spring 88 is welded to the right end of the end piece 87. The other end of the spring 88 is welded to the reinforcing rib 81. The spring 88 can be used to connect the end piece 87.

[0027] The specific implementation process of this utility model is as follows: Wind-resistant columns 5 are added between the main steel frame columns 2 of the multi-span greenhouse, and the bottom of the wind-resistant columns 5 is reliably connected to the greenhouse foundation 1 and other components to ensure that the wind-resistant building steel structure of the greenhouse has a stable supporting foundation. A horizontal pressure beam 6 is set at the top of the wind-resistant columns 5 along the direction of force. Under the action of the horizontal pressure beam 6, the wind load can be effectively transferred and dispersed, enhancing the stability of the entire wind-resistant system. Diagonal horizontal tie rods 7 are set on both sides of the wind-resistant columns 5, and one end of the diagonal horizontal tie rod 7 is connected to the top of the main steel frame column 2, and the other end is connected to the end of the horizontal pressure beam 6 to form a stable triangular structure. The wind load is transferred to the main steel frame column 2 and the main steel frame beam 3 through the wind-resistant columns 5 and the diagonal horizontal tie rods 7, thereby reducing the wind load borne by the end wall purlins 4.

[0028] When the wind-resistant column 5 is installed with the greenhouse foundation 1 using bolts, the welded reinforcing rib 81 can contact the greenhouse foundation 1. Then, the push end 82 drives the screw 83 and the extrusion head 84 through the reinforcing rib 81, so that the screw 83 contacts the greenhouse foundation 1. Then, the push end 82 drives the screw 83 to rotate, so that the screw 83 performs threaded motion, thus installing the screw 83. When the screw 83 drives the extrusion head 84 to rotate and move forward, when the extrusion head 84 contacts the clamping plate 8... When the inclined end of 6 contacts, under the pressure of the extrusion head 84, the end piece 87 can be moved, causing the spring 88 to deform, and finally the clamping plate 86 contacts the surface of the screw 83. Under the action of force, the clamping plate 86 slides along the surface of the screw 83. When the clamping plate 86 slides into the clamping groove 85, the spring 88 returns to its original deformation, so as to pull the clamping plate 86 into the clamping groove 85, and use it to connect the end 82, thereby limiting the screw 83 and preventing the screw 83 from vibrating and loosening.

[0029] This solution enhances the overall structural stability by using a combination of wind-resistant columns 5, horizontal pressure beams 6, and diagonal horizontal tie rods 7. This effectively improves the wind resistance of the end walls of the multi-span greenhouse, ensuring its safe use in severe weather conditions. It also allows for a reduction in the cross-section of the end wall purlins 4, significantly reducing steel usage and directly lowering the construction cost of the multi-span greenhouse. Furthermore, the smaller cross-section of the end wall purlins 4 reduces sunlight obstruction, increasing the amount of light entering the greenhouse and providing more ample illumination for crop growth, thus improving crop yield and quality. The end caps 82 and screws 83 secure the reinforcing ribs 81, providing auxiliary reinforcement to the wind-resistant columns 5. The slots 85 and clamps 86 limit the movement of the end caps 82, preventing vibration, deflection, or loosening of the screws 83, ensuring the long-term stability of the wind-resistant columns 5.
