Description

Technical Field

[0001] This utility model relates to the field of wind pressure resistance reinforcement technology for vegetable greenhouses, and in particular to a wind pressure resistance reinforcement device for vegetable greenhouses. Background Technology

[0002] Vegetable greenhouses are agricultural facilities built using solar energy and insulation materials. They are mainly used for growing off-season vegetables and achieve year-round production by regulating temperature and light. With the development of high-yield production, the application of greenhouses has become more and more widespread. Currently, greenhouses are used for potted flowers and cut flowers, fruit tree production for cultivating grapes, strawberries, watermelons, melons, peaches and citrus fruits, etc., and forestry production for seedling cultivation and ornamental tree cultivation.

[0003] An existing wind-resistant and pressure-resistant greenhouse (publication number: CN211322255U) has multiple arched frames connected to T-shaped frames by reinforcing ribs. However, under strong external forces, the adjacent frames have weak synergistic force and limited pressure resistance, making them prone to relative displacement and resulting in a decrease in overall stability. Furthermore, the counterweight bucket is only weighted by adding water, and the fluidity of the water makes its center of gravity unstable, making it prone to swaying and tipping over in strong winds, thus failing to provide stable counterweight support. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a wind-pressure-resistant reinforcement device for vegetable greenhouses.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A wind-pressure-resistant reinforcement device for vegetable greenhouses includes several arched supports. A triangular truss is installed on the inner top of each arched support using fasteners. Angle bracing plates are fixed to both outer walls of each arched support using bolts. A counterweight box is fixedly installed at the bottom of each of the two angle bracing plates. The counterweight boxes on both outer walls of the arched supports are connected by a steel wire rope, and a second steel wire rope is provided between each pair of adjacent counterweight boxes using metal clips.

[0007] As a further embodiment of this utility model, a diagonal brace is fixedly installed on the upper end of the corner brace, and a hinge seat is provided at the end of the diagonal brace away from the corner brace.

[0008] As a further embodiment of this utility model, the corner brace is movably connected to the hinge seat, and the hinge seat is fixedly installed on the outer wall of the arched bracket.

[0009] As a further embodiment of this utility model, each set of counterweight boxes is embedded with sandbags, and a diagonal reinforcing rod is fixed between the bottom of the triangular truss and the inner wall of the arched support.

[0010] As a further embodiment of this utility model, each group of two adjacent arched supports is fixedly connected by an I-beam tie rod.

[0011] As a further embodiment of this utility model, the middle section of the steel wire rope is connected to the triangular truss by a buckle, and the diagonal reinforcing rods are symmetrically distributed on the triangular truss.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] During the use of vegetable greenhouses, not only are the bending resistance of the top of the arched support reinforced by triangular trusses and diagonal bracing, but also the longitudinal wind resistance of multiple arched supports are improved by connecting them into a whole with I-beam tie rods. Furthermore, the combination of counterweight boxes and ground anchor plates enhances the foundation's grip, and the diagonal bracing effectively transmits lateral wind pressure to the counterweight system to offset the thrust. In addition, the first steel wire rope enables the lateral connection of the counterweight boxes on both sides of a single arched support to balance the force and prevent unilateral overturning. The second steel wire rope enables the longitudinal connection of adjacent counterweight boxes on the same side, forming an overall counterweight belt to resist wind pressure along the arrangement direction and prevent overall slippage. This provides stable and reliable protection for vegetable greenhouses and reduces crop losses caused by wind disasters. Attached Figure Description

[0022] Reference Figures 1-4 A wind-pressure-resistant reinforcement device for vegetable greenhouses includes several arched supports 1. A triangular truss 102 is installed on the inner side of the top of the arched support 1 by fasteners. Angle bracing plates 4 are fixed to the outer walls on both sides of the arched support 1 by bolts. A counterweight box 2 is fixedly installed at the bottom of each angle bracing plate 4. The counterweight boxes 2 on the outer walls on both sides of the arched support 1 are connected by a steel wire rope 202. A steel wire rope 7 is provided between each pair of adjacent counterweight boxes 2 by a metal buckle.

[0023] By adding diagonal reinforcing rods 6 between the inner sides of the two pillars of the triangular truss 102 and the arch support 1, and firmly connecting the three with bolts to strengthen the top structure, the triangular trusses 102 on each group of arch supports 1 are then connected laterally with I-beam tie rods 101. Multiple groups of arch supports 1 are connected into a whole using the I-beam tie rods 101 to improve longitudinal wind resistance. Next, counterweight boxes 2 filled with sandbags 5 are symmetrically placed on both sides of the arch support 1, ensuring that the ground anchor plates 3 at the bottom of the counterweight boxes 2 are embedded in the ground and compacted. At the same time, L-shaped corner bracing plates 4 are installed on the top of the counterweight boxes 2. One end of the diagonal bracing rod 201 is connected to the outer wall of the arch support 1 through a hinge seat 203, and the other end... Fixed to the L-shaped corner support plate 4, the connection is kept taut by adjusting the length of the diagonal brace 201 to achieve effective transmission of lateral force. Then, the two ends of the steel wire rope 202 are connected to the counterweight boxes 2 on both sides of the same set of arched supports 1 with metal clips and pre-tightened to form a lateral tie to balance the force on both sides. Then, the two ends of the steel wire rope 7 are connected to the counterweight boxes 2 on the same side of the two adjacent sets of arched supports 1 with metal clips. All counterweight boxes 2 are connected in series along the longitudinal direction to form an overall counterweight belt. Finally, the installation and fixation of the entire structure are completed. Even in strong winds, it can effectively reduce the risk of swaying, deformation or even collapse of the greenhouse and ensure the stability of the growing environment of vegetables in the greenhouse.

[0024] In this embodiment, a diagonal brace 201 is fixedly installed on the upper end of the corner brace plate 4, and a hinge seat 203 is provided at the end of the diagonal brace 201 away from the corner brace plate 4.

[0025] The triangular truss 102 is composed of multiple structures. The middle section of its bottom rod is connected to the inner wall of the arched support 1 through vertical rods, and diagonal rods are provided on both sides of the vertical rods to form a triangular shape to enhance stability.

[0026] In this embodiment, the corner brace 4 is movably connected to the hinge seat 203, and the hinge seat 203 is fixedly installed on the outer wall of the arched bracket 1.

[0027] The diagonal reinforcement rod 6 is installed at an angle between the bottom end of the triangular truss 102 and the inner wall of the arched support 1, and is firmly connected to both by bolts to form a triangular support structure to enhance the overall stability.

[0028] In this embodiment, each set of counterweight boxes 2 is embedded with sandbags 5, and a diagonal reinforcing rod 6 is fixed between the bottom of the triangular truss 102 and the inner wall of the arched support 1.

[0029] The I-beam tie rod 101 is made of high-strength I-beam steel and is bolted to the triangular truss 102 at both ends by flanges. It is laterally connected to multiple sets of arched supports 1 to enhance the overall longitudinal stiffness.

[0030] In this embodiment, each pair of adjacent arched supports 1 are fixedly connected by an I-beam tie rod 101.

[0031] Filling the counterweight box 2 with sandbags 5 allows the sandbags to provide a stable and flexibly adjustable vertical load for the counterweight box 2 through their own weight, thereby enhancing the positive pressure between the counterweight box 2 and the ground. Combined with the ground anchor plate 3, this further improves the overall structure's anti-slip and anti-overturning capabilities. At the same time, the amount of sandbags 5 can be increased or decreased according to different wind pressure requirements, making it suitable for diverse wind resistance scenarios.

[0032] In this embodiment, the middle section of the steel wire rope 202 is connected to the triangular truss 102 by a buckle, and the diagonal reinforcement rods 6 are symmetrically distributed on the triangular truss 102.

[0033] Use metal clips to connect steel wire rope 1 202 to the counterweight boxes 2 on both sides of the same group of arched support 1, and connect steel wire rope 2 7 to the counterweight boxes 2 on the same side of the adjacent group. By pre-tightening, a horizontal balance and a longitudinal overall counterweight belt are formed to enhance the anti-overturning and anti-slipping capabilities.

[0034] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: During the use of the vegetable greenhouse, by pre-installing triangular trusses 102 on the arched support 1, and adding diagonal reinforcing rods 6 between the triangular trusses 102 and the inner sides of the two pillars of the arched support 1, and firmly connecting the three with bolts to strengthen the top structure, then using I-beam tie rods 101 to connect the triangular trusses 102 on each group of arched supports 1 laterally, and using turnbuckles to pre-tighten multiple groups of arched supports 1 to form an overall frame, improving the longitudinal wind resistance stiffness, then placing counterweight boxes 2 filled with sandbags 5 symmetrically on both sides of the arched support 1, ensuring that the ground anchor plate 3 at the bottom of the counterweight box 2 is embedded in the ground and compacted, and at the same time, in the counterweight box 2. Install L-shaped corner bracing plate 4 at the top. Connect one end of the diagonal brace 201 to the outer wall of the arch support 1 through the hinge seat 203, and fix the other end to the L-shaped corner bracing plate 4. Adjust the length of the diagonal brace 201 to keep the connection in a tight state to achieve effective transmission of lateral force. Then, use metal buckles to connect the two ends of the steel wire rope 202 to the counterweight boxes 2 on both sides of the same arch support 1 and pre-tighten them to form a lateral tie to balance the force on both sides. Then, use metal buckles to connect the two ends of the steel wire rope 7 to the counterweight boxes 2 on the same side of the two adjacent arch supports 1. Connect all the counterweight boxes 2 in series along the longitudinal direction to form an overall counterweight belt. Finally, complete the installation and fixation of the entire structure.
