Description

Technical Field

[0001] This utility model relates to the field of greenhouse construction technology, and in particular to a column installation structure suitable for multi-span greenhouses. Background Technology

[0002] Modern greenhouse facilities offer advantages such as intensification, technological sophistication, and high yield, making them crucial for improving agricultural production efficiency and decisively impacting the quality of agricultural products. Compared to advanced agricultural equipment technologies abroad, my country's greenhouse equipment technology started relatively late, initially relying heavily on imports. However, due to significant differences in climate and geological conditions, corresponding improvements are necessary to achieve better application results. In coastal areas of my country with high wind loads and areas with high seismic intensity, the use of imported large-scale multi-span greenhouses presents the following major drawbacks: the greenhouse structural columns are directly bolted together without considering specific conditions, and the friction between the column base plate and the concrete foundation is insufficient to meet horizontal shear resistance requirements, posing serious safety hazards. Summary of the Invention

[0003] To solve the above problems, this utility model provides a column installation structure suitable for multi-span greenhouses that can realize heating function, specifically adopting the following technical solution:

[0004] The column installation structure suitable for multi-span greenhouses described in this utility model includes a concrete foundation with a shear-resistant groove at the top; a base plate perpendicular to the bottom of the column is provided, the base plate is attached to the bottom of the shear-resistant groove and fixed by a positioning connecting component, and a backfill protective layer flush with the top surface of the concrete foundation is provided in the shear-resistant groove above the base plate.

[0005] The base plate is designed to mimic the shape of the column and is larger than the cross-sectional dimension of the column; the shear groove is a square structure larger than that of the base plate.

[0006] When the column is a cylinder, the positioning and connecting component includes a connecting pin that is set on the base plate and extends downward, and a connecting slot that is pre-embedded in the shear groove; the connecting pins are evenly arranged around the base plate, and the connecting slots correspond one-to-one with the positions of the connecting pins.

[0007] When the column is a square column, the positioning connection component includes right-angled bent parts arranged opposite each other on the side wall of the shear groove. The vertical plate of the right-angled bent part is attached to the side wall of the shear groove and connected by a horizontal anchor bolt and a fixing nut. The horizontal plate of the right-angled bent part is spaced apart from the bottom of the shear groove to form a slot that matches the thickness of the base plate.

[0008] The spacing of the horizontal plates is adapted to the side length of the column.

[0009] The backfill protective layer is made of rigid or flexible materials.

[0010] This utility model provides a column installation structure suitable for multi-span greenhouses. By placing the column base plate within a shear-resistant groove on the top of the concrete, it ensures friction between the column base plate and the concrete foundation while utilizing the concrete sidewalls of the groove to resist horizontal shear forces. This increases the shear resistance at the column-foundation connection, reducing the risk of shear failure in areas with high wind loads and high seismic intensity. A positioning connection component is installed between the column base plate and the shear-resistant groove, improving construction accuracy and convenience. The backfill protective layer seals the shear-resistant groove, increasing the reliability and durability of the column-foundation connection and embedding the positioning connection component within, enhancing the overall aesthetics of the greenhouse. Finally, the backfill material can be either rigid or flexible, depending on the project characteristics. Using flexible materials facilitates later maintenance and component replacement. This utility model has an ingenious structure, is easy to construct, improves column installation accuracy and efficiency, and strengthens the structural safety and stability of the greenhouse, making it significant for promoting the standardized construction of greenhouses.

[0014] Figure 4 yes Figure 3 Top view (without backfill protection layer). Detailed Implementation

[0015] The column installation structure suitable for multi-span greenhouses described in this utility model includes a concrete foundation with a shear-resistant groove at the top; a base plate perpendicular to the bottom of the column is provided, the base plate is attached to the bottom of the shear-resistant groove and fixed by a positioning connecting component, and a backfill protective layer flush with the top surface of the concrete foundation is provided in the shear-resistant groove above the base plate.

[0016] The embodiments of this utility model will be described in detail below with reference to the accompanying drawings. These embodiments are implemented based on the technical solution of this utility model and provide detailed implementation methods and specific construction processes. However, the protection scope of this utility model is not limited to the following embodiments.

[0017] Example 1:

[0018] like Figure 1 ,2 As shown, column 1 is a cylinder, with a base plate 2 welded to its bottom, which is shaped to match the column 1. The base plate 2 is perpendicular to the column 1, and the radius of the base plate 2 is greater than the cross-sectional radius of the column 1. To securely install the column 1, a shear groove 4 is provided on the top of the concrete foundation 3. The shear groove 4 has a square structure, and the side length of the shear groove 4 is greater than the diameter of the base plate 2.

[0019] The positioning and connecting components for connecting the base plate 2 and the shear groove 4 include connecting pins 5 disposed on the base plate 2 and extending downward, and connecting slots 6 pre-embedded in the shear groove 4. In this embodiment, there are four connecting pins 5, which are evenly installed around the periphery of the base plate 2; there are also four connecting slots 6, which are pre-embedded during the pouring of the concrete foundation 3, and their positions correspond one-to-one with those of the connecting pins 5.

[0020] During construction, the column 1 is moved above the concrete foundation 3, aligning the base plate 2 with the shear groove 4. Then, the orientation of the base plate 2 is adjusted according to the relative positions of the connecting pin 5 and the connecting slot 6. After alignment, the column 1 is pressed down, causing the connecting pin 5 to engage with the connecting slot 6. The two are mechanically locked together, at which point the base plate 2 is flush with the bottom of the shear groove 4. Finally, fine aggregate concrete (i.e., rigid material) is poured on top of the base plate 2, filling the shear groove 4. The top surface is smoothed, and after curing, it forms the backfill protective layer 7, flush with the top surface of the concrete foundation 3. Alternatively, the backfill protective layer 7 can also be constructed using flexible materials such as asphalt-impregnated hemp fiber.

[0021] Example 2:

[0022] like Figure 3 , 4 As shown, column 1 is a square column with a base plate 2 welded to its bottom, which is designed to mimic the shape of column 1. The base plate 2 is perpendicular to column 1, and the side length of the base plate 2 is greater than the cross-sectional radius of column 1. To securely install column 1, a shear groove 4 is provided on the top of the concrete foundation 3. The shear groove 4 is square and larger than the size of the base plate 2.

[0023] The positioning connection components for connecting the base plate 2 and the shear groove 4 include a pair of right-angled bends 8, which are fixed to the opposite sidewalls of the shear groove 4. Specifically, the vertical plate of the right-angled bend 8 is attached to the sidewall of the shear groove 4 and connected by a horizontal anchor bolt 9 and a fixing nut 10; the horizontal plate of the right-angled bend 8 is spaced apart from the bottom of the shear groove 4, thus forming a groove adapted to the thickness of the base plate 2. Preferably, the distance between the horizontal plates of the two right-angled bends 8 is adapted to the side length of the column 1. To ensure the smooth installation of the column 1, the length of the shear groove 4 is at least the sum of the length of the right-angled bend 8 and the side length of one side of the column 1. Typically, the right-angled bend 8 can be made of angle steel, which is simple and readily available, and can reduce construction costs.

[0024] One or more horizontal anchors 9 are installed on each side wall and are pre-embedded during the pouring of the concrete foundation 3. The ends of the horizontal anchors 9 extend into the shear groove 4. When installing the right-angle bent piece 8, it is first inserted through the horizontal anchors 9 and pre-tightened with the fixing nut 10 to pre-level the horizontal plate of the right-angle bent piece 8. Then, the column 1 is moved into the shear groove 4 outside the right-angle bent piece 8, so that the column 1 is aligned with the gap of the horizontal plate of the right-angle bent piece 8. Then, the base plate 2 is moved from the end of the groove formed by the horizontal plate and the shear groove 4 towards the center of the right-angle bent piece 8. After reaching the predetermined position, the horizontal plate is adjusted for levelness, and the fixing nut 10 is tightened to complete the installation. Finally, fine stone concrete (i.e., rigid material) is poured on top of the base plate 2 and fills the shear groove 4. The top surface is smoothed and cured to form the backfill protective layer 7 flush with the top surface of the concrete foundation 3. In addition, flexible materials such as asphalt hemp fiber can also be used for backfill protective layer 7.
