Description

Technical Field

[0001] This utility model relates to the field of greenhouse technology, specifically a greenhouse with a reinforced structure. Background Technology

[0002] A greenhouse, also known as a hothouse, is a facility that allows light to pass through while maintaining warmth. Its purpose is to maintain a certain temperature for plant cultivation. During seasons unsuitable for plant growth, it provides a growing environment and increases yield. It is primarily used for cultivating or raising seedlings of warm-weather vegetables, flowers, and trees during cold seasons. Greenhouses come in many types, categorized by their roof frame materials, lighting materials, shape, and heating conditions. Because greenhouses are relatively large and cannot be moved or disassembled after installation, their stability is extremely important.

[0003] Chinese Patent CN221979637U discloses a greenhouse anti-deformation device, relating to the field of greenhouse technology. The device includes a greenhouse body with an anti-deformation device installed on its exterior. The device comprises a top support unit and protective units on both sides of the greenhouse body. The top support unit includes a top gantry plate, with both ends of the top gantry plate resting on an arc-shaped protective top plate. The arc-shaped protective top plate has mortises on both sides, with the top gantry plate located at these mortises. Tenons are located at both ends of the arc-shaped protective top plate, within the protective unit. This invention uses the arc-shaped protective top plate to protect the upper part of the greenhouse body, preventing plant death due to hail or other unexpected events. The mortise and tenon joint between the top gantry plate and the arc-shaped protective top plate enhances the overall rigid connection strength, and the stable triangular structure of the supporting vertical and diagonal support rods further improves stability, thus achieving greenhouse anti-deformation.

[0004] Chinese patent CN221011066U discloses a simplified multi-span greenhouse structure, including two support rods and a pressing rope. Each support rod has a fixed structure at its bottom end, and mounting holes are provided at the top of each rod. Two connecting rods are snapped onto one side of the top of each support rod, and connecting blocks are fixedly installed on each connecting rod. A crossbar is snapped between the other two top sides of the support rods, and locking blocks are fixedly installed at both ends of the crossbar. In this invention, the support rods, connecting rods, crossbars, vertical rods, and arches all form a mortise and tenon structure through mounting holes, connecting blocks, and locking blocks. This mortise and tenon structure effectively increases the greenhouse's wind and pressure resistance. The structure is stable, easy to disassemble, and facilitates repair of damaged areas, making the greenhouse structure more convenient to use and replace, and improving the ease of greenhouse operation.

[0005] Both of the aforementioned prior art patent documents utilize mortise and tenon structures to enhance the overall stability of greenhouses. Meanwhile, this utility model also proposes a new technical solution aimed at addressing the problem of insufficient overall stability in existing greenhouse technologies. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a greenhouse with a reinforced structure, which aims to achieve the technical effect of quick and convenient installation of the frame through mortise and tenon joints, and excellent overall stability of the frame.

[0007] A greenhouse with a reinforced structure includes a frame and a canopy fixed to the outside of the frame. The frame includes several frame members arranged at equal intervals from front to back. Each frame member includes a first crossbeam, a second crossbeam, two third crossbeams, two secondary columns, and two main columns.

[0008] The two auxiliary columns are symmetrically arranged on the left and right, and the two main columns are located between the two auxiliary columns and are symmetrically arranged on the left and right. The height of the main columns is higher than that of the auxiliary columns. The bottom ends of the auxiliary columns and the main columns are respectively provided with auxiliary bases and main bases. The front and rear sides of the auxiliary bases and the main bases are integrally formed with fixing plates. The fixing plates are provided with fixing rods for fixing the fixing plates to the bottom surface. The two main columns are provided with first slots on opposite sides.

[0009] The two third crossbeams correspond to the two secondary columns, and the third crossbeams extend laterally. One bottom end of the third crossbeam is mounted on the top of the secondary column, and the other side of the third crossbeam has an integrally formed first insert for insertion into the first slot in a mating connection manner. The second crossbeam extends laterally and is mounted between the tops of the two main columns. Two symmetrically arranged short columns are integrally formed at the top of the second crossbeam. The first crossbeam extends laterally and is mounted between the tops of the two short columns. A central column is integrally formed at the middle of the top of the first crossbeam, and a front-to-back lateral extension is formed at the middle of the central column. A first through slot runs through the central column. The top of both the secondary and main columns has a lower through slot extending laterally. The bottom of the first, second, and third crossbeams has an upper through slot corresponding to the lower through slot. The upper and lower through slots are joined to form a second through slot that is consistent with the first through slot. A connecting beam extending laterally is inserted into both the first and second through slots. The connecting beam is used to connect the various frames. Ridges are erected between the tops of several corresponding central columns, between the tops of several corresponding first crossbeams, between the tops of several corresponding second crossbeams, and between the tops of several corresponding third crossbeams.

[0010] By adopting the above technical solution, both the secondary base and the main base are fixed to the ground using fixing plates and fixing rods. The secondary column is fixed to the ground via the secondary base, and the main column is fixed to the ground via the main base. A connecting beam inserted between the second crossbeam and the main column allows the second crossbeam to be stably supported between the tops of the two main columns, thus connecting the two main columns. A connecting beam inserted between the third crossbeam and the secondary column allows one side of the third crossbeam to be stably supported at the top of the secondary column. Through the engagement of the first insert and the first slot, the other side of the third crossbeam is also stably connected to the main column. This ensures the third crossbeam is stably connected between the secondary and main columns, thus connecting the secondary and main columns. This integrates the two secondary columns and the two main columns into a single unit. By using connecting beams interlaced between the short uprights and the first crossbeam, the first crossbeam can be stably supported between the tops of the two short uprights. With the first crossbeam stable, the central column, integrally formed at the top of the first crossbeam, also remains stable. Therefore, a single frame can maintain relative stability, while the various frames are connected by several connecting beams, thus forming a highly stable skeleton.

[0011] Meanwhile, because the central column, first crossbeam, second crossbeam, and third crossbeam are at decreasing heights, the top of the frame forms a triangle, which further enhances the overall stability of the frame. Furthermore, laying the tarpaulin prevents rainwater from accumulating on it.

[0012] Furthermore, a ridge beam is installed, which on the one hand further connects the various frames, thereby improving the overall stability of the skeleton; on the other hand, the canopy is fixed to each ridge beam with nails, which improves the connection stability between the canopy and the skeleton.

[0013] This invention eliminates the need for welding during assembly; the frame can be quickly and easily assembled using mortise and tenon joints, resulting in excellent overall stability.

[0014] A further feature of this invention is that a first reinforcing beam extending laterally to the left and right is connected between the secondary column and the main column. A second insert block is integrally formed on both the left and right sides of the first reinforcing beam. A second slot is provided on both the secondary column and the main column for the second insert block to be inserted in a mating connection manner.

[0015] By adopting the above technical solution, the installation of the first reinforcing beam improves the connection stability between the secondary column and the main column, thereby enhancing the stability of the frame.

[0016] A further feature of this invention is that a second reinforcing beam extending laterally to the left and right is connected between the two main columns. A third insert block is integrally formed on both sides of the second reinforcing beam. A third slot is provided on both main columns for the third insert block to be inserted in a mating connection manner.

[0017] By adopting the above technical solution and setting the second reinforcing beam, the connection stability between the two main columns is improved, thereby enhancing the stability of the frame.

[0018] A further feature of this invention is that the top of the central column, the top of the first crossbeam, the top of the second crossbeam, and the top of the third crossbeam are all provided with semi-circular limiting grooves into which the bottom end of the spine can be inserted for a mating connection.

[0019] By adopting the above technical solution, when erecting the spine, the bottom end of the spine is inserted into the semi-circular limiting groove in a mating connection manner, thereby improving the stability of the spine.

[0020] A further feature of this invention is that the bottom ends of the first, second, and third crossbeams are all provided with positioning grooves, and the top ends of the auxiliary columns, main columns, and short columns are all integrally formed with positioning posts for insertion into the positioning grooves in a mating connection manner.

[0021] By adopting the above technical solution, when erecting the first, second, and third crossbeams, the positioning slots are aligned with the positioning posts. Inserting the positioning posts into the positioning slots improves the stability of the first, second, and third crossbeams.

[0022] A further feature of this invention is that the top of the sub-base has a first mounting groove into which the bottom end of the sub-column can be inserted in a mating connection manner, the depth of the first mounting groove being at least one-sixth of the length of the sub-column; and the top of the main base has a second mounting groove into which the bottom end of the main column can be inserted in a mating connection manner, the depth of the second mounting groove being at least one-sixth of the length of the main column.

[0023] By adopting the above technical solution, the bottom end of the secondary column can be inserted into the first mounting groove, allowing for quick installation of the secondary column onto the secondary base. Furthermore, since the depth of the first mounting groove is at least one-sixth of the length of the secondary column, the stability between the secondary column and the secondary base is ensured, preventing the secondary column from swaying under strong winds. Similarly, the installation of the main column is also quick, convenient, and stable.

[0024] A further feature of this invention is that the spine and the connecting beam are fixedly connected by fastening bolts.

[0025] By adopting the above technical solution, the installation of fastening bolts can improve the stability of the spine and connecting beams.

[0026] A further feature of this invention is that a positioning plate is integrally formed on one side of the bottom end of both the connecting beam and the spine.

[0027] By adopting the above technical solution and setting the positioning plate, the connecting beams and ridge beams can be quickly positioned and aligned with the threaded holes on the connecting beams and ridge beams when they are erected, thus facilitating the insertion of fastening bolts.

[0028] Compared with the prior art, the beneficial effects of this utility model are:

[0029] A greenhouse with a reinforced structure is disclosed. During assembly, no welding is required. The frame can be quickly and easily assembled by means of mortise and tenon joints, and the overall stability of the frame is excellent. Attached Figure Description

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] A type of greenhouse with a reinforced structure, such as Figures 1-4As shown, it includes a frame and a canopy 1 fixed to the outside of the frame.

[0037] The frame consists of several frame members arranged at equal intervals from front to back. The frame members include a first reinforcing beam 2, a second reinforcing beam 3, a first crossbeam 4, a second crossbeam 5, two third crossbeams 6, two secondary columns 7, and two main columns 8.

[0038] Two secondary columns 7 are symmetrically arranged on the left and right. Two main columns 8 are located between the two secondary columns 7 and are symmetrically arranged on the left and right. The height of the main columns 8 is higher than that of the secondary columns 7.

[0039] The bottom ends of the secondary column 7 and the main column 8 are respectively provided with a secondary base 25 and a main base 26. The top end of the secondary base 25 has a first mounting groove into which the bottom end of the secondary column 7 can be inserted for a mating connection. The depth of the first mounting groove is at least one-sixth of the length of the secondary column 7. The top end of the main base 26 has a second mounting groove into which the bottom end of the main column 8 can be inserted for a mating connection. The depth of the second mounting groove is at least one-sixth of the length of the main column 8. Fixing plates 9 are integrally formed on the front and rear sides of both the secondary base 25 and the main base 26. Fixing rods 10 are provided on the fixing plates 9 for fixing them to the bottom surface. The fixing rod 10 is a mature existing technology and will not be specifically described in this embodiment. The fixing rod 10 can be referred to as the "fixing structure" in a simple multi-span greenhouse structure in Chinese Patent No. CN221011066U, the "threaded limiting rod" in a greenhouse with a reinforced structure in Chinese Patent No. CN222442481U, and the "installation buried component" in a new type of greenhouse structure in Chinese Patent No. CN215582732U.

[0040] The first reinforcing beam 2 extends laterally from left to right, connecting the secondary column 7 and the main column 8. A second insert 11 is integrally formed on both the left and right sides of the first reinforcing beam 2. Both the secondary column 7 and the main column 8 have second slots for the second insert 11 to be inserted in a mating connection manner.

[0041] The second reinforcing beam 3 extends laterally from left to right and connects between the two main columns 8. A third insert 12 is integrally formed on both sides of the second reinforcing beam 3. Each of the two main columns 8 has a third slot into which the third insert 12 can be inserted for a mating connection.

[0042] Two third crossbeams 6 correspond to two secondary columns 7 respectively. The third crossbeams 6 extend laterally to the left and right. The bottom end of one side of the third crossbeam 6 is mounted on the top of the secondary column 7. The other side of the third crossbeam 6 has a first insert block 13 integrally formed. The main column 8 has a first slot into which the first insert block 13 can be inserted in a mating connection manner.

[0043] The second crossbeam 5 extends laterally and is positioned between the tops of the two main columns 8. The top of the second crossbeam 5 has two short columns 14 that are symmetrically arranged on the left and right sides.

[0044] The first horizontal beam 4 extends laterally and is positioned between the tops of the two short columns 14.

[0045] A central column 15 is integrally formed at the top center of the first crossbeam 4. A first through groove extending laterally and penetrating the central column 15 is provided at the center of the central column 15.

[0046] Both the secondary column 7 and the main column 8 have a lower through slot 16 extending laterally from front to back at their top ends. The bottom ends of the first crossbeam 4, the second crossbeam 5, and the third crossbeam 6 each have an upper through slot 17 corresponding to the lower through slot 16. The upper through slot 17 and the lower through slot 16 are joined together to form a second through slot that is consistent with the first through slot.

[0047] Both the first and second through slots are fitted with connecting beams 18 extending laterally. The connecting beams 18 are inserted between the frames to connect them.

[0048] A ridge beam 19 is installed between the tops of several corresponding central columns 15, between the tops of several corresponding first crossbeams 4, between the tops of several corresponding second crossbeams 5, and between the tops of several corresponding third crossbeams 6. The ridge beam 19 is installed between each frame. Several threaded through holes are provided on the ridge beam 19, and several threaded countersunk holes corresponding to the threaded through holes are provided at the top of the connecting beam 18. Several fastening bolts 20 are used to securely connect the ridge beam 19 and the connecting beam 18 through the threaded through holes and the threaded countersunk holes. A positioning plate 21 is integrally formed on one side of the bottom end of both the connecting beam 18 and the ridge beam 19.

[0049] The top of the central column 15, the top of the first crossbeam 4, the top of the second crossbeam 5, and the top of the third crossbeam 6 are all provided with semi-circular limiting grooves 22 into which the bottom end of the spine 19 can be inserted for a matching connection.

[0050] The bottom ends of the first crossbeam 4, the second crossbeam 5, and the third crossbeam 6 are all provided with positioning grooves 23, and the top ends of the auxiliary column 7, the main column 8, and the short column 14 are all integrally formed with positioning posts 24 for inserting into the positioning grooves 23 in a mating connection manner.

[0051] In this embodiment, the first reinforcing beam 2, the second reinforcing beam 3, the first crossbeam 4, the second crossbeam 5, the third crossbeam 6, the secondary column 7, the main column 8, the short column 14, the central column 15, the connecting beam 18, and the ridge beam 19 are all composed of inner rods and outer tubes. The inner tubes are made of wood, and the outer tubes are made of stainless steel. The outer tubes are fitted over the inner rods and fixed with nails. In this embodiment, the secondary base 25 and the main base 26 are both cast using cement and molds.

[0052] The assembly process of the frame is as follows: First, assemble each frame element sequentially, with each element spaced evenly from front to back. When assembling the frame, pour cement into the mold, and after it cools and solidifies, demold to form the sub-base 25 and main base 26. Then, place the two main bases 26 and two sub-bases 25 at approximately equal intervals. Next, insert the two main columns 8 into the two main bases 26 respectively, and insert the two sub-columns 7 into the two sub-bases 25 respectively. This allows for quick installation of the sub-columns 7 onto the sub-bases 25 and the main columns 8 onto the main bases 26. Since the depth of the first mounting groove is at least one-sixth of the length of the sub-column 7, and the depth of the second mounting groove is at least one-sixth of the length of the main column 8, stability between the sub-columns 7 and sub-bases 25, and between the main columns 8 and main bases 26, is ensured, preventing the sub-columns 7 and main columns 8 from swaying under strong winds. Then, the first reinforcing beam 2 is connected between the secondary column 7 and the main column 8 through the insertion and engagement of the second insert block 11 and the second slot. The installation of the first reinforcing beam 2 improves the connection stability between the secondary column 7 and the main column 8. The second reinforcing beam 3 is connected between the two main columns 8 through the insertion and engagement of the third insert block 12 and the third slot. The installation of the second reinforcing beam 3 improves the connection stability between the two main columns 8. The first reinforcing beam 2 and the second reinforcing beam 3 together improve the overall stability of the frame. In this embodiment, when actually inserting the first reinforcing beam 2 and the second reinforcing beam 3, the main base 26 and the secondary base 25 can be moved left and right to ensure that the first reinforcing beam 2 and the second reinforcing beam 3 can be smoothly inserted and installed.

[0053] Then erect the first crossbeam 4, the second crossbeam 5, and the third crossbeam 6.

[0054] When the second crossbeam 5 is erected, the positioning groove 23 at the bottom of the second crossbeam 5 is aligned with the positioning post 24 on the main column 8. When the second crossbeam 5 is laid flat between the tops of the two main columns 8, the positioning post 24 is inserted into the positioning groove 23.

[0055] When erecting the third crossbeam 6, the positioning groove 23 at the bottom of the third crossbeam 6 is aligned with the positioning post 24 on the secondary column 7. When the third crossbeam 6 is laid flat on top of the secondary column 7, the positioning post 24 is inserted into the positioning groove 23. Then, the first insert 13 is inserted into the first slot. In this embodiment, when actually erecting the third crossbeam 6, the secondary base 25 can be moved left and right to ensure that the first insert 13 can be smoothly inserted into the first slot.

[0056] When the first crossbeam 4 is erected, the positioning groove 23 at the bottom of the first crossbeam 4 is aligned with the positioning post 24 on the short column 14. When the first crossbeam 4 is laid flat between the tops of the two short columns 14, the positioning post 24 is inserted into the positioning groove 23.

[0057] The stability of the first crossbeam 4, the second crossbeam 5, and the third crossbeam 6 can be improved by the insertion and engagement between the positioning pin 24 and the positioning groove 23.

[0058] Next, connecting beams 18 are inserted between the frames through the first and second through slots until the positioning plates 21 at the bottom of each connecting beam 18 are engaged with the front side of the foremost frame. The positioning plates 21 serve to position the connecting beams 18.

[0059] Then, each spine beam 19 is erected between the frames. When erecting the spine beam 19, its bottom end is inserted into the semi-circular limiting groove 22 in a mating connection manner, thereby improving the stability of the spine beam 19. Furthermore, when erecting the spine beam 19, the positioning plate 21 at the bottom end of the spine beam 19 is secured to the front side of the foremost frame. The positioning plate 21 serves to position the connecting beam 18. This ensures that the threaded through hole aligns with the threaded countersunk hole, and a fastening bolt 20 is inserted between the threaded through hole and the threaded countersunk hole. The fastening bolt 20 enhances the stability of the spine beam 19 and the connecting beam 18.

[0060] Next, the auxiliary bases 25 and the main base 26 are fixed to the ground by the fixing rods 10.

[0061] Finally, the canopy 1 is laid, and the canopy 1 is fixed to the ridge beam 19 and the secondary column 7 with nails. In this embodiment, a through hole can be opened in the canopy 1, and a metal eyelet ring can be fixed in the through hole. The nail passes through the metal eyelet ring and is fixed to the ridge beam 19 and the secondary column 7, and the top cap is pressed on the canopy 1.

[0062] It is worth noting that in this embodiment, the first plug 13, the second plug 11 and the third plug 12 can be fixed with screws after they are plugged in.

[0063] This invention utilizes a connecting beam 18 inserted between the second crossbeam 5 and the main column 8 to stably support the second crossbeam 5 between the tops of the two main columns 8, thus connecting the two main columns 8. Similarly, the connecting beam 18 inserted between the third crossbeam 6 and the secondary column 7 allows one side of the third crossbeam 6 to be stably supported on the top of the secondary column 7. Through the engagement of the first insert 13 and the first slot, the other side of the third crossbeam 6 is also stably connected to the main column 8. This ensures the third crossbeam 6 is stably connected between the secondary column 7 and the main column 8, thus connecting the secondary column 7 and the main column 8. Ultimately, this integrates the two secondary columns 7 and the two main columns 8 into a single unit. By using connecting beams 18 intersecting between the short columns 14 and the first crossbeam 4, the first crossbeam 4 can be stably supported between the tops of the two short columns 14. With the first crossbeam 4 stable, the central column 15, integrally formed at the top of the first crossbeam 4, also remains stable. Therefore, a single frame can maintain relative stability, while the various frames are connected by several connecting beams 18, thus forming a skeleton with excellent stability.

[0064] Meanwhile, because the central column 15, the first crossbeam 4, the second crossbeam 5, and the third crossbeam 6 are at decreasing heights, the top of the frame forms a triangle, which further enhances the overall stability of the frame. Furthermore, laying the canopy 1 prevents rainwater from accumulating on it.

[0065] Furthermore, a spine 19 is provided, which on the one hand further connects the various frames through the spine 19, thereby further improving the overall stability of the frame; on the other hand, the canopy 1 is fixed to each spine 19 with nails, which can improve the connection stability between the canopy 1 and the frame.

[0066] This invention eliminates the need for welding during assembly; the frame can be quickly and easily assembled using mortise and tenon joints, resulting in excellent overall stability.
