Description

Technical Field

[0001] The utility model relates to the technical field of assembled steel structures, in particular to an assembled steel structure multifunctional agricultural ecological cabin. Background Art

[0002] At present, aquaculture models mainly include: traditional pond farming below the ground, artificial box farming half above the ground and completely above the ground. Depending on whether there is a shelter on the top, it can be divided into greenhouse farming and open-air farming.

[0003] Pond farming (including semi-exposed box farming) requires land excavation, which not only destroys the original topography, but also affects the stability of the soil. Geological landslides and ecological environmental damage caused by pond excavation are not uncommon.

[0004] Artificial box farming that is completely exposed to the ground usually requires hardening of the land, which will lead to the destruction of the original soil ecological environment and natural resources. At the same time, whether it is open-air farming or greenhouse farming, its ability to resist natural disaster risks is weak. Disasters such as typhoons, rainstorms, floods or mudslides can have a devastating impact on them; and the excrement in the farming process is often discharged directly into the surrounding environment without treatment, causing serious pollution to the groundwater.

[0005] In addition, whether it is aquaculture or crop planting, the output varieties per unit area of ​​land are often too single, the land is not used efficiently, and the economic benefits cannot be maximized.

[0006] Although in the prior art, prefabricated steel structures have been widely used in various industries, for example, a Chinese patent published on March 28, 2023 with patent publication number CN218739439U discloses a lightweight, detachable oxygen chamber with the characteristics of disassembly, light weight, simplified assembly, modularity, high durability, corrosion resistance, acid and alkali resistance, etc.; however, the current prefabricated steel structures are usually used in construction, and it has not been found that prefabricated steel structures are used in agriculture to take into account both aquaculture and crop planting per unit area of ​​land to increase the added value of agricultural production.

[0045] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0046] Example: Figure 1-7 As shown:

[0047] The main body of the agricultural ecological cabin adopts a steel frame structure. The steel material is cold-bent thin-walled steel. The various components are connected by bolts. It has the advantages of light weight and easy installation and disassembly.

[0048] The agricultural ecological cabin includes a base module 1, a steel frame column network module 2, a mezzanine module 3, a side maintenance module 4, a roof structure module 5, and a roof photovoltaic system module 6. The base module 1 and the roof structure module 5 are formed with a breeding area and a working area 73 through the steel frame column network module 2. The breeding area includes two functional areas, namely, an upper breeding area 72 and a lower breeding area 71. Figure 2 , Figure 3 shown.

[0049] like Figure 4As shown, the base module 1 includes a base support system 11 and a bottom slope structure 12. The base support system 11 has high rigidity, which can provide sufficient overall anti-deformation capacity for the agricultural ecological cabin and avoid the necessity of hardening the land; the bottom slope structure 12 provides convenience for sewage discharge and cleaning of aquaculture.

[0050] The base support system 11 includes a longitudinal main truss structure 111 and a transverse support secondary truss structure 112 that are crisscrossed to form a grid structure. The longitudinal main truss structure 111 and the transverse support secondary truss structure 112 are plug-in connected by an inserted non-directional splicing structure, and then the two are fixed together by bolts. A short core column 1121 is welded on the top of the longitudinal main truss structure 111 / transverse support secondary truss structure 112, and an upper chord member is arranged on the top of the longitudinal main truss structure 111 / transverse support secondary truss structure 112. The bottom slope structure 12 is welded by square steel pipes, and a clamp 121 is arranged at the bottom of the bottom slope structure 12. The clamp 121 is clamped and matched with the upper chord member of the longitudinal main truss structure 111, and then the two are fixed together by bolts. The space above the bottom slope structure 12 corresponds to the breeding area.

[0051] The longitudinal main truss structure 111 and the transverse supporting secondary truss structure 112 are both frame structures, leaving space in the horizontal direction. This space can provide necessary space for laying pipelines. The pipelines do not need to be buried underground, which reduces construction complexity and various problems that may arise in subsequent use.

[0052] The steel frame column grid module 2 is mainly composed of a plurality of independent and vertically arranged steel frame columns 21. Each steel frame column 21 bears vertical and horizontal loads and is the main load-bearing component of the agricultural ecological cabin.

[0053] The sandwich module 3 divides the breeding area into two functional areas, the upper breeding area 72 and the lower breeding area 71, which are mainly used to enrich / expand the product types of the agricultural ecological cabin and can be flexibly set according to needs in actual applications. The lower breeding area 71 is mainly used for breeding aquatic products, while the upper breeding area 72 is mainly used for planting crops, placing breeding feed, hatching aquatic seedlings, etc. The working area is mainly used to place the corresponding equipment such as the water circulation system equipment 731 and the constant temperature system equipment 732 required for breeding and for the daily work of the breeding personnel.

[0054] like Figure 5As shown, the side maintenance module 4 includes an upper maintenance subunit 42 and a lower maintenance subunit 41, which are combined with the wall panels to form the outer protective wall and inner partition wall of the eco-cabin. The side maintenance module 4 is connected to the steel frame column 21 by bolts or screws, which can not only provide lateral support for the steel frame column 21, reduce the calculated length of the steel frame column 21 around the weak axis, and thus improve the overall bearing capacity of the steel frame column 21, but also form a lateral resistance whole with the frame column 21 and the wall panels to jointly resist the horizontal load including internal water pressure and external wind load.

[0055] The lower maintenance subunit 41 has vertical ribs, mainly to ensure stronger resistance to lateral pressure (especially water pressure). In specific applications, the design scheme can be appropriately adjusted according to the actual use scenario. The side maintenance module 4 forms the breeding area 71, 72 / working area 73 into an independent space.

[0056] The roof structure module 5 is mainly used to bear the dead loads such as roof beams, purlins, and ceilings, live loads such as snow loads and construction loads, and part of the loads transmitted by the suspension cables 32 of the mezzanine module 3; it can also serve as a supporting structure for the roof photovoltaic system module 6. The roof structure module 5 is mainly composed of roof beams and purlins, and both of the roof beams and purlins are square steel tube sections. Small short columns are welded at the lower flanges of the roof beams to be plugged and installed on the steel frame columns; small square tubes are welded at a certain distance on the upper flanges of the roof beams to connect and fix the purlins.

[0057] The main purpose of the roof photovoltaic system module 6 is to convert solar energy into electrical energy, which can not only achieve energy conservation and emission reduction, green and low-carbon goals, but also the stored electricity can play an emergency role when a large area of ​​power outages occurs in the region, avoiding the loss of farmers caused by the death of aquatic products due to long-term lack of oxygen. This module can be selected independently according to the actual needs of the project.

[0058] Figure 6 The insertion type heterogeneous splicing structure is given by taking the connection between the frame column 21 and the transverse supporting secondary truss structure 112 as an example, and other similar heterogeneous connections can adopt this structure. The short core column 1121 is pre-welded at the end of the transverse supporting secondary truss structure 112, and the steel frame column 21 is inserted into the short core column 1121, and then fixed together by bolts, thereby realizing the rigid assembly connection between the heterogeneous components.

[0059] like Figure 6 As shown, the sandwich module 3 is a floor system mainly composed of a "non"-shaped sandwich beam 31. One end of the sandwich beam 31 (with a short column welded thereto) is inserted into the hollow corbel 211 of the steel frame column 21, and the other end (free end) of the sandwich beam 31 is connected to the roof structure module 5 through a sling 32. Adjacent sandwich beams 31 are connected by multiple C-shaped small steel beams, thereby forming an orthogonal "sandwich beam 31 + C-shaped small beam" main and secondary beam floor system.

[0060] In order to achieve the purpose of lightweight transportation, large components (such as beams, columns, etc.) are usually split into sub-components that meet the transportation (or handling) conditions, and the sub-components are connected by an inner core type same-direction splicing structure. Figure 7 As shown, the inner core type same-direction splicing structure includes a same-direction sub-component 81, an inner core splicing piece 82 and a bolt 83. The same-direction sub-component 81 and the inner core splicing piece 82 are pre-opened at corresponding positions. After the two same-direction sub-components 81 are close to each other at one end and are respectively inserted into the inner core splicing piece 82, the bolts 83 are passed through the pre-opened holes to connect the same-direction sub-components 81 on both sides with the inner core splicing piece 82 respectively, thereby realizing the rigid connection of the fully assembled same-direction components.

[0061] The above-mentioned embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
