Description

Technical Field

[0001] The utility model relates to the technical field of agricultural engineering, in particular to a single-tube skeleton. Background Art

[0002] Solar greenhouses are the most widely used type of vegetable production facilities in northern my country, and are of great significance for ensuring the supply of vegetables in northern China in winter. Solar greenhouses are a kind of civil structure. In addition to meeting the light and temperature requirements for crop growth, they should also have certain structural safety and stability, and be able to bear crop loads, wind loads and snow loads. The skeleton is an important component of the solar greenhouse to bear the load. Among them, the truss arch is one of the most common skeleton structures of the solar greenhouse. This structure can convert the internal force of the skeleton into the axial force of the rod, thereby improving the cross-sectional utilization efficiency and the structural stability of the arch. In recent years, due to the rising construction costs of solar greenhouses and the mechanization and scale development of vegetable production, the skeleton of the solar greenhouse has been continuously developing towards single-tube, column-free and large-span directions. However, compared with the truss arch, the existing single-tube arch has the problem of insufficient cross-sectional stiffness and strength, poor structural stability, and is prone to damage and collapse under load.

[0003] In order to solve the problem of low strength and insufficient wind and snow resistance of large-span single-tube arch frames, methods such as increasing the cross-sectional area of ​​steel pipes or setting up reinforced columns are generally used. However, with the rise in steel prices in recent years, the use of larger-section steel pipes for skeleton construction will greatly increase investment costs, and the installation of reinforced columns will hinder the operation of agricultural machinery and equipment and reduce production efficiency. In addition, current research and development is mainly focused on skeletons with a span of 8-10m. There is a lack of 12m-span single-tube skeletons with high wind and snow resistance, which makes it difficult to provide technical support for the development of large-span solar greenhouses.

[0004] Therefore, how to provide a low-cost, high-strength, large-span single-tube skeleton is a problem that technical personnel in this field need to solve urgently. Utility Model Content

[0005] In view of this, the utility model provides a single-tube skeleton to solve the problem that the cost, strength and production efficiency of the existing large-span single-tube skeleton cannot be effectively balanced.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0007] A single-tube frame includes a rear wall, a front roof, a rear roof and a plurality of groups of single-tube arch frames, each group of the single-tube arch frames includes:

[0010] The second support rod is obliquely arranged on the outside of the arch frame body, and the first end of the second support rod is fixed to the connection between the rear wall column and the roof frame, and the second end is fixed to the foundation embedded part.

[0014] Preferably, the first pull rod is connected to the rear wall column and the front roof frame through a connecting piece.

[0015] Preferably, it further comprises a second tie rod, wherein the second tie rod is fixed to the first end of the second support rod, and an extending direction of the second tie rod is consistent with an extending direction of the single-tube skeleton.

[0031] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0032] like Figure 1 As shown, an embodiment of the utility model provides a single-tube skeleton, including a rear wall, a front roof, a rear roof and a plurality of groups of single-tube arch frames, wherein the plurality of groups of single-tube arch frames are extended along the length direction of the rear wall to form the entire single-tube skeleton.

[0033] Among them, each group of single-tube arch frames at least includes an arch frame body 100, a first support rod 200 and a second support rod 300. The first support rod 200 is arranged on the inner side of the arch frame body 100, and the second support rod 300 is arranged on the outer side of the arch frame body 100. The first support rod 200 and the second support rod 300 work together to suppress the deformation of the arch frame body 100 and improve the overall strength and load of the single-tube arch frame.

[0034] In some embodiments of the utility model, the arch frame body 100 includes a rear wall column 110 and a roof frame connected to the top of the rear wall column 110. One end of the rear wall column 110 is fixed to the foundation embedded part close to the rear wall, and the other end extends upward along the direction perpendicular to the ground along the rear wall to connect with the roof frame.

[0035] Optionally, the roof frame includes a front roof frame 130 and a rear roof frame 120, and both ends of the rear roof frame 120 are respectively connected to the rear wall column 110 and the front roof frame 130, and the connection between the rear roof frame 120 and the front roof frame 130 is arched, and the arch height is higher than the highest point of the rear wall column 110, and the other end of the front roof frame 130 extends toward the ground away from the side of the rear wall column 110 and is fixed to the foundation embedded part, and the greenhouse frame is formed by the front roof frame 130, the rear roof frame 120, the rear wall column 110 and the ground.

[0036] Optionally, the rear wall columns 110, the rear roof frame 120, and the front roof frame 130 are spliced ​​or integrally formed, preferably integrally formed, which can effectively enhance the strength of the arch frame body 100 itself.

[0037] In some embodiments of the present invention, the first support rod 200 is arranged on the inner side of the arch frame body 100, and the first end of the first support rod 200 is fixed to the connection between the rear wall column 110 and the rear roof frame 120, and the second end is fixed to the middle of the front roof frame 130.

[0038] The "middle" is not the middle position of the front roof frame 130 in an absolute sense, but can be understood as a certain position of the front roof frame 130 close to the end of the rear roof frame 120. Preferably, the first support rod 200 is inclined, that is, the height of the first end of the first support rod 200 from the ground is lower than the height of the second end from the ground.

[0039] It is understandable that the front roof frame 130 of the single-tube frame is easily deformed by external pressure and may even collapse in severe cases. Therefore, by providing a first support rod 200, a support force opposite to the external pressure can be provided to the front roof frame 130, thereby preventing the front roof frame 130 from deforming due to external pressure and improving the overall strength and compressive resistance of the single-tube frame.

[0040] In some embodiments of the utility model, the second support rod 300 is obliquely arranged on the outside of the arch frame body 100, and the first end of the second support rod 300 is fixed to the connection between the rear wall column 110 and the rear roof frame 120, and the second end is fixed to the foundation embedded part.

[0041] It is understandable that if the roof frame of the single-tube frame is subjected to a large external pressure, the rear wall column 110 will also be affected and deformed. Therefore, by setting a second support rod 300, a force opposite to the external pressure can be provided to the rear wall column 110, thereby effectively avoiding deformation of the rear wall column 110 and further improving the overall strength and compressive resistance of the single-tube frame.

[0042] In some embodiments of the present invention, the arch frame body 100, the first support rod 200, and the second support rod 300 are all polygonal steel pipes, for example, they can be rectangular, pentagonal, hexagonal or other irregular shapes, preferably rectangular steel pipes.

[0043] It can be understood that compared with circular steel pipes, polygonal steel pipes have a larger cross-sectional coefficient, which can enhance the overall strength of the skeleton, reduce bending stress, and enable it to withstand higher compressive and load-bearing capacities. The use of polygonal steel pipes can effectively reduce the amount of steel used and reduce costs. At the same time, the combination of the first support rod 200 and the second support rod 300 can enhance the overall stability of the skeleton.

[0044] In some embodiments of the present invention, since the arch frame body 100 is the main force-bearing component and the first support rod 200 and the second support rod 300 are auxiliary force-bearing components, the cross-sectional areas of the first support rod 200 and the second support rod 300 do not exceed the cross-sectional area of ​​the arch frame body 100.

[0045] Optionally, the arch body 100 is formed by bending a rectangular steel tube with a cross-sectional size of 55 mm×38 mm×2.5 mm, and the first support rod 200 and the second support rod 300 are both made of a rectangular steel tube with a cross-sectional size of 35 mm×14 mm×2 mm. It should be noted that the sizes of the arch body 100, the first support rod 200, and the second support rod 300 are not limited thereto and can be adjusted according to actual conditions.

[0046] In some embodiments of the present invention, the single-tube arch frame further includes a first tie rod 400, which is located at the bottom of the first support rod 200, and the first end of the first tie rod 400 is fixed to the middle of the rear wall column 110, and the second end is fixed to one end of the front roof frame 130 close to the foundation embedded part. The "middle" is not the middle position of the rear wall column 110 in an absolute sense, but can be understood as a position between the two ends of the rear wall column 110.

[0047] Optionally, the first tie rod 400 is arranged parallel to the ground, and the height of the first tie rod 400 from the ground is 2-2.5m, preferably 2.2m. By arranging the first tie rod 400, a force can be given to the rear wall column 110 and the roof frame toward the inside of the single-tube frame to avoid deformation of the single-tube frame toward the outside caused by excessive supporting force of the first support rod 200 and the second support rod 300, so that the overall stability of the single-tube arch frame is better.

[0048] Optionally, the first pull rod 400 is connected to the rear wall column 110 and the front roof frame 130 through a connector 600. Specifically, the connector 600 may be an iron ring, and the first pull rod 400 may be a steel wire rope with a diameter of 10 mm. The iron ring is fixed to the rear wall column 110 and the front roof fixture, and the steel wire rope is connected to the rear wall column 110 and the front roof frame 130 through the iron ring. The operation is simple and convenient, and it is found through operation that when the single-tube arch frame is subjected to a large pressure, the use of the steel wire rope can maintain the stability of the single-tube arch frame, thereby avoiding the use of a large amount of steel and saving costs.

[0049] In some embodiments of the present invention, the single-tube arch frame further includes a second tie rod 500 , which is fixed to the first end of the second support rod 300 , and the extension direction of the second tie rod 500 is consistent with the extension direction of the single-tube frame.

[0050] The second tie rod 500 is provided to not only provide stability connection between adjacent groups of single-tube arch frames, but also further suppress deformation of the arch frame body 100, thereby reducing the probability of the arch frame body 100 being damaged by bending, and improving the overall strength and compressive resistance of the single-tube skeleton.

[0051] In some embodiments of the utility model, a plurality of connecting rods 700 are further included, and the extension direction of each connecting rod 700 is consistent with the extension direction of the single-tube skeleton. The plurality of connecting rods 700 are distributed on both sides of the second pull rod 500, and are used to connect adjacent rear wall columns 110, adjacent rear roof columns 120, and adjacent front roof columns 130, so that multiple groups of single-tube arch frames are connected to form a single-tube skeleton.

[0052] In some embodiments of the utility model, the span of the single-tube arch frame is 12m, there is no column inside, the ridge height is 5.5m, the arch frame body 100 is bent by a rectangular steel tube with a cross-sectional size of 55mm×38mm×2.5mm, the first support rod 200 and the second support rod 300 are both rectangular steel tubes with a cross-sectional size of 35mm×14mm×2mm, and the first pull rod 400 is a steel wire rope with a diameter of 10mm.

[0053] If a conventional single-tube arch frame consisting of only floor-standing steel tube arch frames and hollow-circular steel tubes is used to construct a single-tube arch frame, a Φ88.9mm×4.0mm hollow-circular steel tube is required to meet the same load as that of the embodiment of the utility model, but the amount of steel used is 47.5% more than that of the embodiment.

[0054] In summary, the single-tube skeleton and single-tube arch frame provided by the utility model has high structural stability, can effectively bear loads such as wind and snow, solves the problems of high steel consumption in large-span single-tube arch frames and the need to set up reinforced columns in the planting area, has the advantages of small steel consumption, low cost, high light utilization, and no hindrance to planting operations, and can provide technical support for the development of large-span single-tube skeletons.

[0055] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
