Description

TECHNICAL FIELD

[0001] The utility model relates to agricultural facilities technical field especially relates to a stand hidden type sunlight greenhouse. BACKGROUND

[0002] The sunlight greenhouse is the abbreviation of energy-saving sunlight greenhouse, also called warm shed, which is composed of two side walls, maintenance back wall, support frame and covering material. It is a kind of greenhouse type unique in northern China. The heat is stored and released through the absorption of solar energy by the back wall, so that the indoor temperature can be maintained without heating, meeting the growth needs of vegetable crops.

[0003] The existing sunlight greenhouse frame has small bearing capacity. When snow disaster or strong wind weather occurs, the greenhouse frame may collapse. In order to make the greenhouse frame bear pressure better, a stand is usually added in the middle of the greenhouse frame. However, the stand brings inconvenience to the production of crops in the greenhouse, such as the movement of vehicles entering the greenhouse is very limited, and the layout of the site is also affected.

[0004] In order to solve the above technical problems, the technical scheme disclosed in the Chinese invention patent with the patent application number CN201810618510.3 is a triangular space truss and large-span non-column greenhouse, which comprises upper chord and lower chord and reinforcing rib assembly installed between the upper chord and the lower chord. The reinforcing rib assembly comprises V-shaped pieces and I-shaped pieces assembled into a spatial triangular structure with reinforcing rib grooves; the bottom support structure of the large-span non-column greenhouse adopts a plurality of triangular space trusses described above, and cold-proof trenches and ground piles for installing triangular space trusses are arranged around.

[0005] However, the above-mentioned prior art has the following technical problems: in the above-mentioned triangular space truss and large-span non-column greenhouse, the triangular space truss is used to enhance the bearing capacity and bearing span of the sunlight greenhouse structure, so that the sunlight greenhouse can be supported without setting up columns. However, when the pressure of the sunlight greenhouse roof is borne by the triangular space truss, each triangular space truss bears the pressure independently. In actual use, due to various reasons, such as snow covering the roof of the sunlight greenhouse, the actual pressure borne by each triangular space truss is different. When one of the triangular space trusses bends or subsides due to high pressure, the pressure originally borne by the triangular space truss will be dispersed to the remaining triangular space trusses to varying degrees, so that the weight borne by the other triangular space trusses increases, resulting in poor overall pressure bearing capacity of the sunlight greenhouse roof and affecting the stability of the sunlight greenhouse.

Detailed Implementation

[0022] The technical solutions and effects of the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0023] Please refer to Figures 1 to 2This utility model provides a column-mounted concealed solar greenhouse 10, including a greenhouse body 20, several supporting steel beams 30, and several crossbeams 40. The greenhouse body 20 includes a rear wall 21 and two side walls 22. One end of each supporting steel beam 30 is fixedly connected to the ground, and the other end is fixedly connected to the top surface of the rear wall 21. Both ends of each crossbeam 40 are fixed to the two side walls 22, so that the crossbeams 40 and supporting steel beams 30 are arranged in a grid pattern on the surface of the greenhouse body 20. Each crossbeam 40 is fixedly connected to all supporting steel beams 30, and all crossbeams 40 are along the side walls. The curved surface at the top of the 22 is designed to distribute the pressure borne by the supporting steel beams 30 to the greenhouse body 20 through each supporting steel beam 30 and the crossbeam 40. Since the crossbeam 40 is connected to all the supporting steel beams 30, when each supporting steel beam 30 is under pressure, the pressure can be distributed to the other supporting steel beams 30 through the crossbeam 40. This distributes the pressure from the greenhouse roof to the supporting steel beams 30 evenly to all the supporting steel beams 30. Furthermore, the two ends of the crossbeam 40 are fixedly connected to the side wall 22, which can also distribute the pressure borne by the supporting steel beams 30 to the side wall 22.

[0024] Please refer to Figure 3 Furthermore, each supporting steel beam 30 includes a first steel pipe 31, a second steel pipe 32, and several supporting steel pipes 33. The two ends of the first steel pipe 31 are fixedly connected to the two ends of the second steel pipe 32, and the first steel pipe 31 is located directly above the second steel pipe 32. The two ends of each supporting steel pipe 33 are fixedly connected to the first steel pipe 31 and the second steel pipe 32, and the end of any supporting steel pipe 33 connected to the first steel pipe 31 is fixedly connected to the end of the adjacent supporting steel pipe 33 connected to the first steel pipe 31. The end of any supporting steel pipe 33 connected to the second steel pipe 32 is fixedly connected to the end of the adjacent supporting steel pipe 33 connected to the second steel pipe 32, so as to disperse the pressure of the first steel pipe 31 through the second steel pipe 32 and the supporting steel pipes 33, thereby enhancing the compressive strength of the supporting steel beam 30.

[0025] In this embodiment, each supporting steel beam 30 is integrally cast to facilitate the construction of the column-concealed solar greenhouse 10 and reduce the cost of the column-concealed solar greenhouse 10.

[0026] Please refer to Figure 4 In this embodiment, each crossbeam 40 is located above the connection point of two adjacent supporting steel pipes 33 and the second steel pipe 32, and is fixedly connected to the two supporting steel pipes 33. When the crossbeam 40 is fixedly installed at the bottom of the first steel pipe 31 or the bottom of the second steel pipe 32, the crossbeam 40 can only disperse the downward pressure of the first steel pipe 31 or the second steel pipe 32. However, through the fixing method in this embodiment, the crossbeam 40 can not only disperse the downward pressure of the second steel pipe 32, but also disperse the inward squeezing force of the supporting steel pipe 33, thereby enhancing the bearing capacity of the supporting steel beam 30.

[0027] Please refer to Figure 3 Furthermore, the column-mounted concealed solar greenhouse 10 also includes several reinforcing steel beams 50. Each reinforcing steel beam 50 is fixed to the rear wall 21 at the connection position between each supporting steel beam 30 and the rear wall 21 of the greenhouse body, so as to increase the compressive strength of the rear wall 21. The top of each reinforcing steel beam 50 is fixedly connected to one end of the supporting steel beam 30 at the corresponding position, and the bottom end is fixedly connected to the ground, so as to distribute the pressure borne by the supporting steel beam 30 and enhance the compressive strength of the supporting steel beam 30.

[0028] Furthermore, the column-mounted concealed solar greenhouse 10 is also equipped with two cement bases 60. The two cement bases 60 are respectively set at the end where each supporting steel beam 30 is connected to the ground and at the end where each reinforcing steel beam 50 is connected to the ground, so as to prevent the soil strength of the ground from being insufficient to support the supporting steel beam 30 or the reinforcing steel beam 50. It can also connect the end of each supporting steel beam 30 connected to the ground into one piece, so that the pressure distributed on each supporting steel beam 30 is more even.

[0029] Please refer to Figure 5 In this embodiment, a first pressure plate 34 is provided at the connection between each supporting steel beam 30 and the cement base 60 to distribute the pressure borne by the cement base 60 to the surrounding area; a second pressure plate 35 is provided at the connection between each supporting steel beam 30 and the reinforcing steel beam 50 to distribute the pressure borne by the reinforcing steel beam 50 to the surrounding area; and a third pressure plate 51 is provided at the connection between each reinforcing steel beam 50 and the cement base 60 to distribute the pressure borne by the cement base 60 to the surrounding area.

[0030] In this embodiment, a protective layer is provided on the outer side of the rear wall 21 and the side wall 22. The protective layer is made of heat-insulating and corrosion-resistant materials, such as black cotton felt, to prevent the surface of the rear wall 21 and the side wall 22 from being corroded by weather such as rain and snow. A cement slurry layer is also coated on the protective layer to prevent the protective layer from catching fire and to improve the fire resistance of the protective layer.

[0031] This invention, based on a traditional pillarless greenhouse, connects all supporting steel beams 30 by adding crossbeams 40. This allows the pressure on each supporting steel beam 30 to be transferred to the others via the crossbeams 40, preventing bending or deformation of a single beam due to excessive pressure, which could increase the pressure on the remaining beams and affect the overall load-bearing capacity of the greenhouse. Furthermore, the addition of a cement base 60 not only enhances the load-bearing capacity of the supporting steel beams 30 but also prevents… The pressure exerted on the ground by each supporting steel beam 30 is different, resulting in different amounts of sinking of each supporting steel beam 30 into the ground. This leads to a height difference in the roof of the column-concealed solar greenhouse 10. Furthermore, due to the increased load-bearing capacity of the top of the column-concealed solar greenhouse 10, the curvature of the supporting steel beams 30 can be increased during the construction of the column-concealed solar greenhouse 10, increasing the space of the column-concealed solar greenhouse 10. In addition, the position of the condensate return flow of the roof of the column-concealed solar greenhouse 10 can be moved forward, increasing the space available for planting crops in the column-concealed solar greenhouse 10.

[0032] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
