Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sealing structures for capping expansion joints of greenhouses, in particular to a soft connection structure for expansion joints of greenhouses. Background Art
[0002] In recent years, glass greenhouses have been increasingly used for growing high-quality fruits and vegetables. Due to the different temperature requirements of fruit and vegetable cultivation and the greenhouse's supporting plumbing and heating equipment, large glass greenhouses are typically divided into growing and service areas, covered with different materials, and expansion joints are installed in the gap between the growing and service areas. However, uneven foundation settlement or sudden temperature changes can create height differences and gaps at the top of the expansion joints, reducing the greenhouse's sealing. This can lead to heat loss within the greenhouse and increased air flow between the interior and exterior, increasing the risk of plant diseases.
[0003] Most greenhouse expansion joints now use galvanized steel plates as flexible joints, creating a fixed angle between the two sides of the steel plates, which are then fixed to the water channels on either side. While this method can create a tight seal and adjust the expansion joint to accommodate slight temperature fluctuations, the inherent limitations of the steel plates can lead to insufficient expansion and contraction when the foundation settles or the temperature fluctuates dramatically. The significant temperature and humidity differences between indoor and outdoor greenhouses can cause condensation on the inner surface of the steel plates, which can adversely affect production personnel and the greenhouse environment.
[0004] Therefore, in response to the current problems, how to provide a greenhouse expansion joint soft connection structure that can ensure the sealing of the greenhouse and avoid the adverse effects of dripping caused by temperature difference on production personnel and the internal environment of the greenhouse is an issue that technical personnel in this field urgently need to solve. Utility Model Content

[0009] The thermal insulation layer is located on the upper surface of the support frame and is fixed on the upper surface of the support frame.
[0010] Through the above technical solution, the utility model provides a soft connection structure for a greenhouse expansion joint. The arc-shaped support frame increases the expansion and contraction ductility of the expansion joint, so that the greenhouse expansion joint can cope with the movement of the greenhouse structure in the case of foundation settlement or sudden temperature change; at the same time, an insulation layer is provided on the upper surface of the support frame to help reduce the temperature difference between the inside and outside of the greenhouse, solve the problem of dripping at the expansion joint position, and ensure that the internal environment of the greenhouse is not affected.
[0011] Preferably, the above-mentioned greenhouse expansion joint flexible connection structure further comprises a thermal insulation fixing layer, wherein the thermal insulation fixing layer is located on the upper surface of the thermal insulation layer and fixed to the upper surface of the thermal insulation layer to ensure the fixation of the thermal insulation layer.
[0012] Preferably, the greenhouse expansion joint flexible connection structure further includes a sealing layer, located between the support frame and the insulation layer and fixed to the upper surface of the support frame. This ensures the sealing of the expansion joint, preventing outside air from entering the greenhouse through the gap and causing changes in the greenhouse temperature and air environment.
[0013] Preferably, the greenhouse expansion joint flexible connection structure further includes a plurality of mounting plates, each of which is grouped in pairs. Each mounting plate is fixed to the side wall of the water tank at the top of the greenhouse, and both ends of the support frame, the sealing layer, and the thermal insulation fixing layer are fixed to a group of mounting plates to ensure the stability of the support frame installation.
[0014] Preferably, in the above-mentioned greenhouse expansion joint flexible connection structure, the mounting plate and the vertical direction of the water tank have a preset angle to achieve sufficient drainage of rainwater.
[0015] Preferably, in the above-mentioned greenhouse expansion joint flexible connection structure, the interval between each group of mounting plates is 30 cm.
[0016] Preferably, in the above-mentioned greenhouse expansion joint flexible connection structure, the sealing layer is made of rubber.
[0017] It can be seen from the above technical solutions that, compared with the prior art, the present invention provides a greenhouse expansion joint flexible connection structure, which has the following beneficial effects:
[0018] The utility model increases the expansion and ductility of the expansion joint by making the supporting frame arc-shaped, so that the greenhouse expansion joint can cope with the movement of the greenhouse structure in the case of foundation settlement or sudden temperature change; at the same time, arranging an insulation layer on the upper surface of the supporting frame helps to reduce the temperature difference between the inside and outside of the greenhouse, solves the problem of dripping at the expansion joint position, and ensures that the internal environment of the greenhouse is not affected.
