Abstract
Description
Technical Field
[0001] This utility model relates to building structures specifically for the livestock industry, and more specifically to a multi-story pigsty structure system with a simplified structure. Background Technology
[0002] With the large-scale and intensive development of my country's animal husbandry, pig farming is moving towards high density, high efficiency, environmental protection, and intelligentization. Increasingly scarce land resources and ever-rising environmental requirements have made multi-story, vertical pig houses an important choice for modern large-scale pig farms. Multi-story pig houses can significantly improve land utilization, achieve centralized management and disease control, and reduce unit farming costs.
[0003] However, the traditional multi-story pigsty construction model faces serious challenges in terms of efficiency, cost, quality, and environmental protection. These challenges are mainly manifested in:
[0004] (1) Low construction efficiency and long construction period: Traditional multi-story pig houses mostly adopt cast-in-place reinforced concrete frame structure or masonry structure. There are many wet operations on site (such as formwork, steel bar binding, concrete pouring, and wall construction), the procedures are complicated, and they are greatly affected by the weather, resulting in a long construction period (usually several months or even longer), which cannot meet the needs of rapid production, delays the breeding plan, and increases the investment recovery period.
[0005] (2) High costs: Labor costs continue to rise, wet operations on site require a large amount of labor, there is relatively more material waste, and the long construction period also brings higher financial and management costs.
[0006] (3) High difficulty in quality control: There are many on-site construction links and human factors have a significant impact. It is difficult to effectively guarantee the accuracy of component dimensions, concrete pouring quality, and reliability of connection nodes, which can easily lead to structural hazards or building quality problems (such as cracks and leakage).
[0007] (4) Significant environmental impact: The site generates a large amount of construction waste, sewage, dust and noise, which does not conform to the concept of green building and sustainable development.
[0008] (5) Increased structural complexity: Multi-story pig houses bear heavy loads (live load, equipment load, feed load) and require consideration of manure removal processes. However, the manure ditch, as a core functional component of multi-story pig houses, is usually only considered as a non-load-bearing maintenance or partition structure on its sidewalls. In order to bear the floor load and meet the requirements of structural integrity, it is often necessary to set up independent structural beams (such as lintels or transfer beams) in the manure ditch area, or to add beams between columns. This increases the complexity of the structure, the amount of materials used, and the construction cost, while also encroaching on valuable building space (especially floor height).
[0009] In recent years, prefabricated buildings have been widely used in industrial and civil construction due to their advantages such as fast construction speed, controllable quality, and green environmental protection. In agricultural construction, especially in the field of pigsty, prefabricated technology (such as light steel structure, precast concrete slab, etc.) has also begun to be applied. However, the existing prefabricated technologies applied to pigsty still have the following key problems: (1) The structural system is disconnected from the process requirements: The design focus of most existing prefabricated pigsty structural systems is on the rapid installation of the main structure, and it has failed to fully consider and deeply integrate the unique process requirements of pigsty, especially the core position of the manure treatment system. The manure ditch structure usually still adopts the traditional on-site casting or prefabrication method, and its side wall is still just a functional partition component, which has failed to participate in the main structure's load-bearing capacity; (2) Low standardization and poor versatility: Existing prefabricated pigsty components are often designed for specific projects, lacking a unified modular and standardized system, making it difficult to adapt to the flexible needs of pigsties of different scales and process layouts. The component reuse rate is low, resulting in high mold cost amortization.
[0010] In summary, the current status of prefabricated pig house technology is as follows: (1) Redundant structural system: In order to support the floor load, it is still necessary to set up independent structural beams above or next to the manure ditch, resulting in waste of materials and space; (2) Limited overall structure: The non-structural manure ditch sidewalls contribute little to the overall structural stiffness; (3) Complex connection: The connection nodes between the prefabricated manure ditch components and the main structural beams and columns are complex, affecting the construction speed and reliability; (4) Insignificant overall cost advantage: Due to insufficient standardization, the components are not multifunctional (such as the manure ditch only undertakes a single function), and the possible increase in transportation and hoisting costs, the overall cost advantage of existing prefabricated pig houses is sometimes not obvious, which hinders its large-scale promotion.
[0011] Therefore, there is an urgent need to develop an innovative, streamlined multi-story pigsty structure system. This system should be able to deeply integrate the needs of building structure and breeding process, especially by giving the core process component "manure ditch" a structural function, maximizing the use of component functions, achieving "multi-purpose use of one item", reducing redundant components, optimizing space utilization, and realizing the construction of truly efficient, low-cost, high-quality, and green prefabricated multi-story pigsties. Utility Model Content
[0012] In view of the technical problems existing in the prior art, the purpose of this utility model is to provide a simplified multi-layer pigsty structure system, which directly uses the manure ditch module as the load-bearing structure, thus simplifying the overall structure.
[0013] To achieve the above objectives, the present invention adopts the following technical solution:
[0014] A structurally concise multi - layer pigsty structure system includes a bearing platform arranged on a foundation and a load - bearing frame arranged on the bearing platform. The load - bearing frame includes structural columns, transverse ground beams, cross beams, longitudinal beams, structural slabs, and manure ditch modules that form a multi - layer frame structure. Among them, the transverse ground beam is located on the first floor and is laid on the bearing platform, and the cross beam is located on the second floor and above. The side walls of the manure ditch module are integrally arranged with the longitudinal beams of the load - bearing frame. The bottom plate of the manure ditch module and the channel bottom plate serve as the structural slabs of the load - bearing frame. The cross beam is laid on the structural column. The manure ditch module is laid on the transverse ground beam or cross beam. The manure leakage plate is arranged above the manure ditch module. At the connection node between the structural column and the side wall of the manure ditch module, a corbel is arranged on the side facing the manure ditch, and this corbel is used to lay the manure leakage plate. A corbel is also arranged on the side facing the channel at the connection node between the structural column and the side wall of the manure ditch module, and this corbel is used to lay the channel bottom plate.
[0015] As a preference, the manure ditch module is designed in two forms, namely the integral form and the assembled form, which are as follows.
[0016] The manure ditch module is an integral “mountain” - shaped structure, including three side walls and a bottom plate. The ends of the entire manure ditch module are directly placed on two transverse ground beams / cross beams. The manure ditch module forms two manure ditches along the longitudinal direction.
[0017] The manure ditch module is an assembled structure, including three side walls and two bottom plates. Among them, the three side walls are two side side walls and one middle side wall respectively. One side of the bottom of the side side wall extends out a wing, forming an L - shape, and both sides of the bottom of the middle side wall extend out a wing respectively, forming an inverted T - shape. The bottom plate is laid between the wings of the side side wall and the middle side wall. After assembly, it forms a “mountain” - shape. The ends of the side side wall and the middle side wall are both directly placed on two transverse ground beams / cross beams. The manure ditch module forms two manure ditches along the longitudinal direction.
[0018] As a preference, in each manure ditch module, the three side walls simultaneously serve as load - bearing longitudinal beams, and two steel bars extend out from the upper and lower parts of both end faces of each side wall. After the manure ditch module is hoisted and completed, the steel bars extend into the structural column and together with the vertical main bars and horizontal stirrups of the structural column form the steel bar framework of the connection node between the structural column and the side wall of the manure ditch module. The connection node is poured with slightly expanded concrete to realize the connection between the structural column and the manure ditch module.
[0019] As a preference, for the integral manure ditch module, two rows of steel bars extend out from both longitudinal ends of the bottom plate. After the manure ditch module is hoisted and placed on the transverse ground beam / cross beam, the steel bars extending out from the bottom plates of adjacent manure ditch modules are connected to each other, serving as the post - pouring belt of the bottom plate of the manure ditch module. Slightly expanded concrete is poured in the post - pouring belt of the bottom plate to realize the connection between the bottom plates of adjacent manure ditch modules.
[0020] As a preferred option, for the assembled manure trench module, each side wing has a steel bar extending from both ends, one above the other. After the side wall is hoisted and placed on the transverse ground beam / beam, the steel bars extending from adjacent side wings are connected to form a post-cast strip for the side wing. Micro-expansion concrete is poured into the post-cast strip of the side wing to connect adjacent side wings. The bottom plate is placed directly on the side wing of the side wall. The longitudinal adjacent bottom plates are sealed with high-performance concrete. The bottom plate and the side wall, as well as the bottom plate and the middle side wall, are also sealed with high-performance concrete.
[0021] As a preferred embodiment, the top surface of the corbel used for laying the manure slats is flush with the top surface of the side wall of the manure ditch module; the crossbeam uses a non-removable steel truss floor deck as the bottom formwork for pouring its concrete, and the non-removable steel truss floor deck is placed on the top surface of the lower structural column; the passageway bottom plate uses a non-removable steel truss floor deck as the bottom formwork for pouring its concrete, and the non-removable steel truss floor deck is placed on the corbel on the side of the structural column.
[0022] As a preferred embodiment, a row of longitudinally arranged L-shaped steel bars extends from the top of the side wall of the manure trench module near the bottom plate of the channel, and the L-shaped steel bars serve as the connecting key between the side wall of the manure trench module and the bottom plate of the channel.
[0023] As a preferred embodiment, the longitudinal length of a manure trench module is a standard module, and the longitudinal spacing of adjacent transverse ground beams / beams corresponds to the longitudinal length module of the manure trench module, which is also a standard module; the longitudinal spacing of the structural columns is the same as the spacing of the transverse ground beams / beams, and the transverse spacing corresponds to the width of a manure trench or the width of a channel; multiple manure trench modules are assembled longitudinally to form a complete manure trench.
[0024] As a preferred option, the transverse ground beams, crossbeams, and structural columns are cast-in-place structures.
[0025] The principle of this utility model is:
[0026] To address the disconnect between the building structure and technological requirements in traditional multi-story pigsties where the core process component—the manure trench—is merely a functional partition, a novel pigsty frame structure is proposed. This system is based on the idea of assigning structural functions to the manure trench sidewalls and floor slabs, respectively serving as structural beams and slabs within the pigsty's load-bearing framework. The system comprises structural columns, transverse ground beams / beams, longitudinal beams (manure trench module sidewalls), and the manure trench module floor slab / channel floor slab. This optimizes the multi-story pigsty structure, effectively reducing material usage and construction costs. The system achieves a deep integration of structural requirements and livestock farming process needs.
[0027] The core component of the pigsty, the manure ditch, is designed as a modular component—the manure ditch module. Based on this, the load-bearing frame is also modularly designed, with the spacing of structural columns and transverse ground beams / beams matching the dimensions of the manure ditch modules. This achieves standardization of the multi-story pigsty structural system, facilitating standardized design and construction.
[0028] The side walls and bottom plate of the manure trench module serve as both load-bearing longitudinal beams and structural slabs, which can simplify the load-bearing structural system of pigsty buildings.
[0029] This utility model has the following advantages:
[0030] 1. Multifunctional components: The core components of pig manure treatment—the sidewalls and bottom slabs of the manure ditch—are used as structural beams and slabs of the load-bearing frame structure of the pig house, respectively. This integrates the process requirements of the pig house with the structural system, making full use of all the components of the building, saving materials, and reducing the floor height of the pig house, resulting in significant economic benefits.
[0031] 2. Component Standardization: Based on the functionalization of the structural system, a modular and standardized multi-layer pig house prefabricated structural system has been created. The prefabricated components have a high degree of standardization and good versatility, which can adapt to the flexible needs of pig houses of different sizes and process layouts. The high component reuse rate significantly reduces the amortization cost of molds, resulting in obvious overall cost advantages.
[0032] 3. Prefabricated components: The construction process of prefabricated multi-story pigsties has been developed, which greatly reduces on-site wet work, lowers the difficulty of construction quality control, and reduces the impact on the surrounding environment, which is in line with the concept of green building.
[0033] 4. Simple and reliable component connection: The connection nodes between the prefabricated manure trench modules and the main structure's transverse ground beams / beams and columns are simple and reliable, effectively improving the efficiency of pigsty construction.
[0034] 5. To achieve the construction of efficient, low-consumption, high-quality, and green prefabricated multi-story pig houses. Attached Figure Description

Detailed Implementation
[0055] The present invention will be further described in detail below with reference to specific embodiments.
[0056] A simplified multi-story pigsty structural system includes a foundation platform and a load-bearing frame mounted on the foundation platform. The load-bearing frame includes structural columns forming the multi-story frame structure, transverse ground beams, horizontal beams, longitudinal beams, structural slabs, and manure trench modules. The transverse ground beams are located on the first floor and are erected on the foundation platform, while the horizontal beams are located on the second floor and above. The sidewalls of the manure trench modules are integrated with the longitudinal beams of the load-bearing frame. The bottom slab of the manure trench modules and the bottom slab of the passageways serve as the structural slabs of the load-bearing frame. The horizontal beams are erected on the structural columns. The manure trench modules are erected on the transverse ground beams or horizontal beams. A slatted floor is installed above the manure trench modules. A corbel is installed at the connection node between the structural column and the sidewall of the manure trench module on the side facing the manure trench, and this corbel is used to lay the slatted floor. A corbel is also installed at the connection node between the structural column and the sidewall of the manure trench module on the side facing the passageway, and this corbel is used to lay the bottom slab of the passageway.
[0057] The structural columns, transverse ground beams / beams, longitudinal beams (side walls of the manure trench module), and the bottom slab of the manure trench module / passageway bottom slab constitute the column, beam, and slab structural system of the entire building. This utility model only focuses on describing the improved parts of the multi-story pigsty; other structures of the multi-story pigsty structure, such as stairs, piping systems, electrical systems, and guardrails, are the same as those in existing technologies.
[0058] The manure collection ditch module, which serves as a collection point for pig manure, is a modular, prefabricated reinforced concrete component. It is designed in two forms: the integral type in Example 1 and the assembled type in Example 2, as follows: Figure 11 and Figure 17 .
[0059] Example 1
[0060] The manure ditch module is an integral “mountain”-shaped structure, including three side walls and a bottom plate, as shown in Figure 2 ; The ends of the entire manure ditch module are directly placed on two transverse ground beams / cross beams; Two manure ditches are formed along the longitudinal direction of the manure ditch module, specifically as shown in Figure 3 .
[0061] In each manure ditch module, the three side walls simultaneously serve as load-bearing longitudinal beams. At the upper and lower parts of both end faces of each side wall, two steel bars (diameter ≥ 14 mm) protrude, as shown in Figure 2 ; After the manure ditch module is hoisted in place, the steel bars extend into the structural column, and together with the vertical main bars and horizontal stirrups of the structural column, they form the steel bar framework of the connection node between the structural column and the side wall, as shown in Figure 3 ; Micro-expansion concrete is poured at this connection node. Through the construction of the connection node, the integrity of the connection node between the side wall of the manure ditch module and the structural column is ensured, as shown in Figure 4 .
[0062] In the integral manure ditch module, two rows of steel bars (diameter ≥ 8 mm, spacing ≤ 150 mm) protrude from both longitudinal ends of the bottom plate, as shown in Figure 2 ; After the manure ditch module is hoisted in place, the steel bars protruding from the bottom plates of adjacent manure ditch modules are connected, as shown in Figure 3 ; As the post-cast strip of the manure ditch module, micro-expansion concrete is poured in the post-cast strip to connect the adjacent bottom plates, as shown in Figure 4 .
[0063] At the connection node between the structural column and the side wall of the manure ditch module, a corbel is provided on the side facing the manure ditch. The corbel is flush with the top surface of the side wall of the manure ditch module and is used for laying the manure leakage plate, as shown in ) Figure 4 ; A corbel is provided on the side facing the passage at the connection node, which is used for setting the bottom formwork of the passage floor in the later stage (i.e., the non-removable steel bar truss floor slab), as shown in Figure 6 .
[0064] At the top of the side wall on the side of the manure ditch module close to the passage floor, a row of longitudinally arranged L-shaped steel bars (diameter ≥ 14 mm, spacing ≤ 150 mm) protrude. The L-shaped steel bars bend towards the passage side, and the L-shaped steel bars serve as the connection keys between the side wall and the passage floor, as shown in Figure 2 and 6 .
[0065] The longitudinal length of a manure ditch module is one standard modulus. The longitudinal spacing of adjacent transverse ground beams / cross beams corresponds to the longitudinal length modulus of the manure ditch module, which is one standard modulus; The longitudinal spacing of the structural columns is the same as the spacing of the transverse ground beams / cross beams, and the transverse spacing corresponds to the width of a manure ditch or the width of a passage respectively; Multiple manure ditch modules are assembled longitudinally to form a complete manure ditch.
[0066] The transverse ground beams, cross beams and structural columns are cast-in-place structures.
[0067] The crossbeams use precast steel truss floor slabs as the bottom formwork for poured concrete; the passageway floor slab also uses precast steel truss floor slabs as the bottom formwork for poured concrete, and is also cast in place on site. These precast steel truss floor slabs are placed on the corbels on the sides of the structural columns, forming a complete passageway after pouring. This construction method eliminates the need for erecting scaffolding to support the formwork.
[0068] Taking a two-story pigsty using an integral manure trench module with its structural columns and transverse ground beams / beams cast in place as an example, the construction process of this utility model is illustrated as follows: (1) foundation construction; (2) excavation of the foundation and transverse ground beams; (3) reinforcement binding, formwork installation, and concrete pouring of the foundation and transverse ground beams (longitudinal reinforcement of the columns needs to be reserved in the foundation), such as Figure 1 (4) The first-floor prefabricated manure trench modules are hoisted. The form of the manure trench modules is shown in the figure. Figure 2 (5) The stirrups at the connection points between the first-floor structural columns and the sidewalls of the manure ditch are tied (see...). Figure 3 (6) Post-pouring strip (including the overlap of the bottom plate of the first-floor manure trench module and the connection node between the manure trench sidewall and the first-floor structural column) micro-expansion concrete pouring, see Figure 4 (7) For the binding of the stirrups and installation of formwork and concrete pouring of the upper part of the first-floor structural columns, it is necessary to reserve the main reinforcement of the second-floor structural columns, see Figure 5 (8) Installation of the first-floor passageway without dismantling the steel truss floor deck (see...) Figure 6 ), rebar tying, side formwork installation and concrete pouring, see Figure 7 (9) Hoisting of the second-floor beam without dismantling the steel truss floor deck (see...) Figure 8 ), rebar tying, side formwork installation and concrete pouring, see Figure 9 (10) Hoisting of the second-floor prefabricated manure trench modules, see Figure 10 (11) Binding of stirrups and installation of formwork at the bottom of the second-floor structural columns; (12) Pouring of micro-expansion concrete for the second-floor post-pouring strip (including the overlap of the bottom plate of the second-floor manure trench module and the connection node between the side wall of the second-floor manure trench and the second-floor structural column); (13) Binding of stirrups, installation of formwork and pouring of concrete at the top of the second-floor structural columns; (14) Installation of the second-floor passageway non-removable steel truss floor deck, binding of steel bars, installation of side formwork and pouring of concrete; (15) Binding of steel bars, installation of formwork and pouring of concrete for roof beams and slabs.
[0069] Example 2
[0070] The manure trench module is a modular structure, comprising three side walls and two base plates. The three side walls consist of two edge side walls and one middle side wall. One side of the bottom of each edge side wall extends out in an L-shape, while each side of the bottom of the middle side wall extends out in an inverted T-shape. The base plate is placed between the side wings of the edge and middle side walls, forming a "mountain" shape after assembly. The ends of both the edge and middle side walls rest directly on two transverse ground beams / beams. The manure trench module forms two manure trenches along the longitudinal direction, as detailed below. Figure 12 and 13 .
[0071] In each manure trench module, three side walls simultaneously serve as load-bearing longitudinal beams. Two reinforcing bars (diameter ≥ 14mm) extend from the upper and lower ends of each side wall. Figure 12 As shown; after the manure trench module is hoisted, the reinforcing bar extends into the structural column, forming a reinforcing steel skeleton for the connection node between the structural column and the side wall together with the vertical main reinforcement and horizontal stirrups of the structural column. This connection node is then constructed with micro-expansion concrete. The construction of the connection node ensures its integrity, as shown... Figure 14 and 15 As shown.
[0072] For the modular manure trench, each side wing has a reinforcing bar (diameter ≥ 8mm) extending from both ends. After the side walls are hoisted, the reinforcing bars of adjacent side wings are connected to form a post-cast strip for the side wings. Micro-expansion concrete is poured into the post-cast strip to connect adjacent side wings. The base plate is placed directly on the side wings. High-performance concrete is used to encapsulate the longitudinal connections between adjacent base plates, between the base plate and the side walls, and between the base plate and the middle side walls. Figure 16 As shown.
[0073] At the connection point between the structural column and the sidewall of the manure ditch, a corbel is installed on the side facing the manure ditch. The corbel is flush with the top surface of the manure ditch sidewall and is used to lay the slatted floor. Figure 15 A corbel is set on the side of the connection node facing the passage for later setting of the bottom formwork of the passage floor slab (i.e., the non-removable steel truss floor slab).
[0074] A row of longitudinally arranged L-shaped steel bars (diameter ≥ 14mm, spacing ≤ 150mm) extends from the top of the sidewall of the manure trench module near the bottom slab of the passage. These L-shaped steel bars bend towards one side of the passage, serving as a key connecting the sidewall to the bottom slab of the passage. Figure 12 and 16 As shown.
[0075] The longitudinal length of a manure trench module is a standard module. The longitudinal spacing of adjacent transverse ground beams / beams corresponds to the longitudinal length module of the manure trench module, which is also a standard module. The longitudinal spacing of the structural columns is the same as the spacing of the transverse ground beams / beams, and the transverse spacing corresponds to the width of a manure trench or the width of a passage. Multiple manure trench modules are assembled longitudinally to form a complete manure trench.
[0076] The horizontal ground beams, crossbeams, and structural columns are cast-in-place structures.
[0077] The crossbeams use precast steel truss floor slabs as the bottom formwork for poured concrete; the passageway floor slab also uses precast steel truss floor slabs as the bottom formwork for poured concrete, and is also cast in place on site. These precast steel truss floor slabs are placed on the corbels on the sides of the structural columns, forming a complete passageway after pouring. This construction method eliminates the need for erecting scaffolding to support the formwork.
[0078] If modular manure trenches are used, the construction process is as follows: (1) foundation construction; (2) excavation of the foundation and transverse ground beams; (3) reinforcement binding, formwork installation and concrete pouring of the foundation and transverse ground beams (longitudinal reinforcement of columns needs to be reserved in the foundation), such as Figure 1 (4) Side wall hoisting of inverted T-shaped and L-shaped manure trench modules; see manure trench module form for details. Figure 12 and 13 (5) The stirrups at the joint between the first-floor structural column and the side wall of the manure ditch are tied (see...). Figure 14 (6) Installation of formwork; (7) Pouring of micro-expansion concrete at the joint between the side wall of the manure ditch and the first-floor structural column, and at the post-pouring strip of the manure ditch side wing, see Figure 15 (7) Laying of the bottom slab of the manure ditch, see Figure 16 (8) Binding of stirrups and installation of formwork and concrete pouring of the upper part of the first-floor structural columns, and the main reinforcement of the second-floor structural columns need to be reserved; (9) Installation of the first-floor passage's steel truss floor slab without dismantling, binding of steel bars, installation of side formwork and concrete pouring; (10) Hoisting of the second-floor beam's steel truss floor slab without dismantling, binding of steel bars, installation of side formwork and concrete pouring; (11) Hoisting of the second-floor inverted T-shaped and L-shaped manure trench sidewalls; (12) Binding of stirrups and installation of formwork at the joint between the second-floor structural columns and the manure trench sidewalls; (13) Pouring of micro-expansion concrete at the joint between the manure trench sidewalls and the second-floor structural columns, and the manure trench side wing post-pouring strip; (14) Paving of the second-floor manure trench bottom slab; (15) Binding of stirrups, installation of formwork and concrete pouring of the upper part of the second-floor structural columns; (16) Installation of the second-floor passage's steel truss floor slab without dismantling, binding of steel bars, installation of side formwork and concrete pouring; (17) Binding of roof beams and slabs, installation of formwork and concrete pouring.

Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.
