Description

Technical Field

[0001] This utility model relates to the field of multi-span greenhouses, and more specifically, to a multi-span greenhouse based on the principle of sealed air insulation. Background Technology

[0002] Chinese patent publication number CN115152484A discloses "a multi-span greenhouse structure and an installation method for the multi-span greenhouse structure." This multi-span greenhouse structure includes multiple rows of central columns and multiple arch truss modules. Each row of central columns supports two rows of opposing arch truss modules. Each arch truss module includes multiple first spacer members and multiple arch frame units. The multiple arch frame units are spaced apart along the extension direction of the first spacer members. Each arch frame unit includes a web member and an arch frame. The web member is connected to the bottom end of the arch frame. At least two first spacer members are spaced apart vertically and connected to the web member, forming the truss section of the arch truss module, replacing the original truss structure built on the central column structure. This greenhouse structure eliminates the need for a separately installed truss structure, facilitating rapid assembly, but it still has the following drawbacks:

[0003] (1) The existing greenhouse roof is a plastic film structure, which has poor light transmission performance and cannot provide effective sunlight to the greenhouse. Moreover, the single-layer plastic film insulation structure has poor protection effect in winter.

[0004] (2) The existing greenhouse has a single support structure, which cannot provide a firm and stable support when encountering strong winds.

[0005] Therefore, we have made improvements and proposed a multi-span greenhouse with a sealed air insulation principle. Utility Model Content

[0006] In view of the problems and defects existing in the prior art, the purpose of this utility model is to provide a multi-span greenhouse based on the principle of sealed air insulation. This greenhouse not only has good light transmission and heat preservation, but is also sturdy and stable when encountering strong winds.

[0007] To achieve the aforementioned objectives, this utility model provides a multi-span greenhouse based on the principle of sealed air insulation: It includes main columns, with a construction assembly between the main columns, and an insulation component mounted on the outer side of the construction assembly; the construction assembly includes auxiliary columns mounted inside the main columns, with surrounding beams alternately installed on the lower outer sides of the auxiliary and main columns, and guy wire beams installed on the upper sides of both the auxiliary and main columns; the insulation component includes an insulation curtain mounted above and below the guy wire beams, with a sealing layer inside the insulation curtain; longitudinal chords are mounted on both sides of the upper side of the guy wire beams, with truss sub-members alternately mounted between the longitudinal chords; external shading columns are mounted on the upper side of the guy wire beams, with external shading longitudinal beams mounted between the external shading columns, and a glass roof mounted on the external shading longitudinal beam assembly; a sealed air layer is mounted on the outer side of the main columns, and a covering film is laid on the outer side of the sealed air layer.

[0008] The surrounding beams are provided in at least four sets.

[0009] The glass roof has an isosceles triangle cross-sectional shape.

[0010] The sealed air layer is an inflatable thermal insulation blanket.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. The greenhouse is constructed by interlacing main columns, auxiliary columns, surrounding beams, and tie beams, which makes the main frame firm and stable. The top of the greenhouse is effectively supported by the truss sub-bars and longitudinal chords. The glass roof is fixedly installed on the upper side of the tie beams to achieve efficient light transmission and ensure the light and temperature inside the greenhouse. The interlacing of the external shading columns and external shading longitudinal beams also facilitates the firm and stable installation of shading cloth on the upper side of the greenhouse to block sunlight as needed.

[0013] 2. The double-layer insulation curtain installed on the west side of the guy wire beam and the sealed air layer inside the double-layer insulation curtain are used to achieve insulation at the top of the greenhouse. The sealing control material layer installed on the side and the overall covering film on the outside are used to improve the insulation effect of the greenhouse side and the whole.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0020] like Figure 1-3 As shown, this embodiment proposes a multi-span greenhouse with a sealed air insulation principle, including main columns 1, a building assembly between the main columns 1, and an insulation component on the outer side of the building assembly.

[0021] The building assembly includes an auxiliary column 201 installed inside the main column 1. The auxiliary column 201 and the main column 1 are interleaved with surrounding beams 208 installed on the lower outer side. Both the auxiliary column 201 and the main column 1 are equipped with tie beams 202.

[0022] The thermal insulation component includes a thermal insulation curtain 301 erected on the upper and lower sides by a tie beam 202. A sealing layer 302, which is a plastic film, is provided inside the thermal insulation curtain 301.

[0023] like Figure 3 As shown, longitudinal chords 203 are provided on both sides of the upper side of the tie beam 202, and truss sub-bars 204 are interlaced between the longitudinal chords 203. The truss sub-bars 204 and the longitudinal chords 203 effectively support the top of the greenhouse.

[0024] like Figure 1 As shown, an external shading column 206 is provided on the upper side of the guy wire beam 202, and an external shading longitudinal beam 207 is provided between the external shading columns 206. The staggered arrangement of the external shading columns 206 and the external shading longitudinal beam 207 also facilitates the firm and stable installation of the shading cloth on the upper side of the greenhouse.

[0025] like Figure 1As shown, the external shading longitudinal beam 207 assembly is equipped with a glass roof 205. Installing the glass roof 205 achieves efficient light transmission, ensuring the light and temperature inside the greenhouse.

[0026] like Figure 1 As shown, a sealing air layer 303 is provided on the outside of the main column 1, and a covering film 304 is laid on the outside of the sealing air layer 303. The sealing control layer on the side and the covering film 304 covering the whole outside improve the heat preservation effect of the greenhouse side and the whole. The covering film 304 is an inflatable heat preservation blanket, which improves the heat preservation effect of the greenhouse side and the whole.

[0027] like Figure 2 As shown, the surrounding beams 208 are provided in at least four sets. The greenhouse is constructed by the main columns 1, auxiliary columns 201, surrounding beams 208 and tie beams 202 in an alternating manner, which makes the main frame firm and stable.

[0028] like Figure 1 As shown, the cross-sectional shape of the glass roof 205 is an isosceles triangle. Installing the glass roof 205 achieves efficient light transmission, allowing light to effectively illuminate from different angles.

[0029] Specifically: The greenhouse, constructed by the staggered main column 1, auxiliary column 201, surrounding beam 208, and tie beam 202, ensures a sturdy and stable main frame. The truss sub-rods 204 and longitudinal chords 203 effectively support the top of the greenhouse. A glass roof 205 is fixedly installed on the upper side of the tie beam 202 to achieve efficient light transmission, ensuring adequate light and temperature inside the greenhouse. The staggered arrangement of the external shading columns 206 and external shading longitudinal beams 207 facilitates the secure and stable installation of shading cloth on the upper side of the greenhouse for sunshading as needed. The double-layer insulation curtain 301 installed on the west side of the tie beam 202, along with the sealed air layer inside the double-layer insulation curtain 301, achieves insulation at the top of the greenhouse. The sealing control material layer on the side and the overall covering film 304 improve the insulation effect of the greenhouse sides and the whole structure.

[0030] All technical features in this embodiment can be freely combined according to actual needs.

[0031] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
