Description

Technical Field

[0001] The utility model relates to a snow-resistant skeleton vault structure of a greenhouse which is convenient for disassembly and assembly, belonging to the technical field of greenhouses. Background Technique

[0002] With the rapid development of modern agriculture, greenhouses, as an important means to adjust the growth environment of crops and improve the yield and quality of crops, have been widely used. As the support system of the greenhouse, the stability and durability of the greenhouse skeleton structure directly affect the overall performance and economic benefits of the greenhouse. Therefore, the research and optimization of the greenhouse skeleton structure have always been important topics in the field of agricultural engineering.

[0003] At present, square steel or steel pipes are commonly used to build the skeleton structure of greenhouses. Generally, the greenhouse is built with steel pipes to form a skeleton space with a span of 8 to 12 meters and a length of 60 to 120 meters; in order to save costs, thin-walled pipes with a wall thickness of 1-2 mm are mostly used for the steel pipes. Generally, a single steel pipe at the top of the greenhouse is bent into an arch shape. However, due to the low bending strength of a single thin-walled steel pipe, when there are severe weather conditions such as strong winds and heavy snow, it is very easy to collapse the greenhouse, causing huge losses to farmers. In addition, most of the existing greenhouse skeletons are welded on-site, with great on-site construction difficulty, difficult installation, low efficiency, and high installation and construction costs. Summary of the Invention

[0004] The technical problem to be solved by the utility model is: the utility model provides a snow-resistant skeleton vault structure of a greenhouse which is convenient for disassembly and assembly, to solve the problem that the greenhouse is easily crushed under severe weather conditions such as strong winds and heavy snow; the utility model adopts a modular design structure, and the connection part is connected by a sleeve and a pin connection structure to ensure easy disassembly and assembly, and solve the problems of large on-site construction difficulty, difficult installation, low efficiency, and high installation and construction costs of most of the existing greenhouse skeletons.

[0005] The technical solution of the utility model is: a snow-resistant skeleton vault structure of a greenhouse which is convenient for disassembly and assembly, including a first arched steel frame 1, a second arched steel frame 2, side brackets 3, inclined brackets 4, a main bracket 5, cross beams 6, main connectors 7, and pin assemblies 8; the second arched steel frame 2 is connected to the left and right first arched steel frames 1, the left and right first arched steel frames 1 are respectively connected to the left and right cross beams 6, both sides of the second arched steel frame 2 are respectively connected to the left and right cross beams 6 through side brackets 3 and inclined brackets 4, the middle of the second arched steel frame 2 is connected to the main connector 7 through the main bracket 5, and the main connector 7 is further respectively connected to the left and right cross beams 6.

[0006] Furthermore, there are two first arched steel frames 1, with the same structure, symmetrically arranged on the left and right about the center of the second arched steel frame 2. The upper ends of the left and right first arched steel frames 1 are respectively sleeved with the left and right ends of the second arched steel frame 2 through first connecting sleeves 21, and are respectively connected and fixed with pin assemblies 8.

[0007] Further, there are two crossbeams 6, with the same structure, one on each side, symmetrically left and right. The lower ends of the left and right first arched steel frames 1 are respectively connected to the left and right crossbeams 6 through first connection blocks 13, and are respectively connected and fixed with pin assemblies 8.

[0008] Further, there are two side brackets 3, with the same structure, one on each side, symmetrically left and right. The upper ends of the left and right side brackets 3 are respectively sleeved on the left and right sides of the second arched steel frame 2 through second connection sleeves 23, and are connected and fixed with pin assemblies 8.

[0009] The lower ends of the left and right side brackets 3 are respectively sleeved on the left crossbeam 6 and the right crossbeam 6 through third connection sleeves 18, and are connected and fixed with pin assemblies 8.

[0010] Further, there are two inclined brackets 4, with the same structure, one on each side, symmetrically left and right. The upper ends of the left and right inclined brackets 4 are respectively sleeved on the left and right sides of the second arched steel frame 2 through fourth connection sleeves 26, and are connected and fixed with pin assemblies 8.

[0011] The lower ends of the left and right inclined brackets 4 are respectively sleeved on the main connector 7 through fifth connection sleeves 30 and eighth connection sleeves 34, and are connected and fixed with pin assemblies 8.

[0012] Further, the upper end of the main bracket 5 is sleeved on the second arched steel frame 2 through a sixth connection sleeve 27, and is connected and fixed with a pin assembly 8.

[0013] The lower end of the main bracket 5 is sleeved on the main connector 7 through a seventh connection sleeve 32, and is connected and fixed with a pin assembly 8.

[0014] Further, the left and right crossbeams 6 are respectively sleeved on the main connector 7 through an upper connection sleeve 36 and a lower connection sleeve 39, and are connected and fixed with pin assemblies 8.

[0015] The beneficial effects of the present utility model are as follows: Since the arch top and the crossbeam of the present utility model adopt a truss skeleton structure, its bending resistance and compressive strength are greatly improved. Through simulation verification, its bending strength and compressive strength are more than 6 times greater than those of round tubes or square tubes of the same model size, thereby improving the overall stability of the greenhouse and greatly enhancing its snow and wind resistance. Secondly, due to the increase in bending strength, the wall thickness of the pipe can be appropriately reduced to save steel and reduce the overall weight. In addition, by adopting a modular design structure, the greenhouse skeleton is divided into several pieces, which is convenient for transportation. The sleeve plus pin connection structure is adopted to ensure easy disassembly and assembly, solve the problem of difficult on-site construction, improve the installation and construction efficiency, and reduce the installation and construction cost.
