Description

Technical Field

[0001] The present invention belongs to the technical field of prefabricated buildings, and particularly relates to a composite wall panel and its structure. Background Art

[0002] The characteristic of prefabricated buildings is modularization. The walls that make up the structure are split into various standard-sized plates and connectors for connecting the plates. Then, all the base materials are customized according to requirements through factory prefabrication and transported to the site for installation, which improves efficiency. Existing prefabricated buildings mostly use precast concrete plates as the wall materials of the structure and screw bolts as the connectors. However, this kind of structure has a large self-weight and is not suitable for the installation requirements of light weight and simplicity. Moreover, the wall structure of container-type plates has low structural strength and poor heat insulation and sound insulation effects. Summary of the Invention

[0003] In order to solve the problems existing in the prior art, the present invention provides a composite wall panel and its structure, aiming to achieve convenient disassembly and light weight through the structural adjustment of the wall panel, and at the same time, to meet the requirements of good sound insulation, heat insulation and other functions.

[0004] The technical solution adopted by the present invention is as follows:

[0005] In the first aspect, the present invention provides a composite wall panel, including a plurality of plate bodies connected and limited by connectors to form a wall panel; each plate body includes at least two base plates, and the base plates forming the same plate body are detachably and limitedly fixed to each other through connectors.

[0006] It should be noted that the plate bodies are combined to form a wall panel, and the wall panels are surrounded to form a structure. The combination method of adjacent plate bodies is that the edges are connected to each other through connectors in a snap-fit manner.

[0007] There are various connection methods for this connector. In order to facilitate rapid assembly and disassembly, it can be set as a snap-fit limit method of groove-piece, that is, the installation direction is different from the main load-bearing direction, or it can also be set as a method of quickly connecting and fixing with bolts.

[0008] The difference from the prior art is that in this embodiment, the so-called plate body is a multi-layer plate structure, and at least two base plates are combined in the same plate body. The connection method between the base plates is different from the prior art, and the above-mentioned connectors are used to achieve snap-fit limit. That is, the same connector can not only realize the connection between the base plates, but also realize the connection between the plate bodies, so as to form the best combination effect.

[0009] It should also be noted that the connecting piece can refer to a general single connecting piece, or a combination of several cooperating connecting pieces, that is, it includes different types of connecting pieces to achieve corresponding functions. Among them, the general single connecting piece is convenient and simple, and has strong versatility, but its structural strength and functionality are poor, and it can only form the same type of plate body or wall panel. The cost of multiple types of connecting pieces is higher than that of single connecting pieces, but it can have more connection methods and functional modes. The core lies in the connection between the substrate and the substrate through the connecting piece, and the connection between the plate body and the plate body through the connecting piece.

[0010] Combined with the first aspect, the present invention provides a first implementation manner of the first aspect. A clamping structure that cooperates with the connecting piece is provided on one side surface of the substrate. The same plate body is formed by the surfaces of two substrates with clamping structures facing each other, and the connecting piece is located between the two substrates.

[0011] This implementation manner defines that a single plate body has two substrates, and the connecting piece is hidden between the two substrates. And a clamping structure is fixedly provided on one side of the substrate itself. That is, the substrate is divided into an inner side and an outer side. The outer side mainly faces the internal environment and the external environment. The regularity of the surface of the plate body can be improved by setting a finish or an ordinary flat surface, so that the plate body forming the wall has two relatively integral surfaces inside and outside.

[0012] Combined with the first aspect, the present invention provides a second implementation manner of the first aspect. The clamping piece has two groups of first enlarged ends that are respectively embedded in adjacent connected plate bodies to form a limit;

[0013] Two groups of second enlarged ends that are respectively embedded in the substrates forming the same plate body are provided on the first enlarged end.

[0014] It should be noted that the connection relationship between the plate bodies is essentially the connection relationship between two groups of substrates. Between the two groups of substrates of adjacent plate bodies, the two first enlarged ends of the same connecting piece are nested with each other to achieve clamping and limiting. The direction of this nesting is perpendicular to the main stress direction of the connecting piece, that is, the pulling force of the two plate bodies on the connecting piece, and the nesting direction is perpendicular to the pulling force.

[0015] And two groups of second enlarged ends that are respectively nested and cooperated with each substrate are also provided on each group of first enlarged ends. That is, the second enlarged end actually achieves clamping and limiting with each substrate. The stress direction of the second enlarged end is the same as the pulling force direction given by the two substrates of the same plate body to the connecting piece, and is also perpendicular to the nesting direction between the second enlarged end and the substrate. And the interaction force between the two substrates is also perpendicular to the interaction force provided by the connecting piece between the adjacent plate bodies.

[0016] In combination with the second embodiment of the first aspect, the present invention provides a third embodiment of the first aspect, wherein the connecting piece is a strip structure extending in the nesting direction of the substrate, and includes a middle connecting portion and a first bulged end arranged on both sides of the connecting portion in a cross-sectional shape taken perpendicular to the length of the connecting piece, and the second bulged end is a portion respectively arranged on both sides of the first bulged end and maintained parallel to the connecting portion.

[0017] It should be noted that the substrate does not limit its specific size. A single board can be composed of several groups of substrates, and two groups of substrates are a classification limitation of the basic structural characteristics of the board, that is, there are two groups of substrates arranged opposite to each other, which can be arranged in the same direction as a long substrate or several short substrates. The splicing method is to extend the length of the connecting piece, so that it is suitable for nesting and connecting multiple substrates arranged in the same direction.

[0018] The so-called cross-sectional shape taken perpendicularly to the length of the connector is because the connector, as a profile structure, has a long extension length, but its structural features are all in its cross-sectional shape, so it is defined with reference to the cross-sectional shape. The main cross-sectional shape of the connector is H-shaped, with the horizontal bar in the middle being the connecting part, and the vertical bars parallel on both sides being the first enlarged end. It should be pointed out that the so-called enlarged end refers to a shape with a certain cross-sectional area that is different from the connecting part, and it is not limited to a straight rod shape, and it only needs to form a certain extension in the direction perpendicular to the length of the connecting part, in order to provide a better limiting effect for the two side plates in the length direction of the connecting part.

[0019] Similarly, the second expanded end can be regarded as an H-shaped structure formed with the first expanded end as the main body. Since the two oppositely arranged substrates constituting the same plate body need to be tightened and limited to each other, the extension direction of the second expanded end is the same as the length direction of the connecting portion. That is, when a single substrate is subjected to a force perpendicular to its surface, the second expanded end provides a limiting effect. If it is subjected to a force parallel to its surface, the first expanded end provides a limiting effect, but the force is transmitted to the first expanded end through the second expanded end, that is, the second expanded end is also subjected to force.

[0020] In combination with the first aspect, the present invention provides a fourth implementation of the first aspect, wherein a filling space filled with a heat-insulating material is provided between adjacent base plates constituting a single plate body.

[0021] In combination with the first aspect or several embodiments of the first aspect, the present invention provides a fifth embodiment of the first aspect, further comprising connecting piles, and adjacent plates are detachably connected to the connecting piles via connecting pieces.

[0022] It should be noted that the plate body has a connection structure for connecting the connecting member, that is, a matching structure provided on the base plate, and adjacent plate bodies can be directly connected through the connecting member. The connecting pile is an additional strip-shaped member, which has two opposite connection structures for matching the connecting member. That is, a single connecting member has two connection ends. In this embodiment, one connection end is connected to the plate body, and the other connection end is connected to the connecting pile, and the transition is realized through the connecting pile.

[0023] It should also be noted that in the wall panel structure of this embodiment, the main base plate itself, as a lightweight material, mainly serves as an isolation function and has poor load-bearing performance. In order to meet the needs of hanging or connecting other structures inside and outside the structure, the provided connecting pile structure has relatively high structural strength, which can not only meet the connection stability requirements of the plate body, but also serve as a hanging point or connection point to provide other functional attributes.

[0024] Combined with the fifth embodiment of the first aspect, the present invention provides a sixth embodiment of the first aspect. The connecting pile includes a split connecting pile and an integral connecting pile. The split connecting pile includes an inner pile and an outer pile that are mutually clamped, and the inner pile and the outer pile are combined to form a clamping structure for connecting at least two plate members.

[0025] Combined with the sixth embodiment of the first aspect, the present invention provides a seventh embodiment of the first aspect. The outer pile includes at least two sub-parts, and the sub-parts are clamped and limited by the inner pile.

[0026] Combined with the sixth embodiment of the first aspect, the present invention provides an eighth embodiment of the first aspect. The clamping structure is separately provided on the inner pile or the outer pile.

[0027] It should be noted that the clamping structure itself, as a connection structure, needs to cooperate with the connecting member to achieve clamping and limiting. However, since the split connecting pile itself is also connected by clamping and limiting, there are two setting methods, that is, the inner pile and the outer pile respectively have a part of the connection structure, and a complete connection part is formed by combination. In this way, the design characteristics of a similar mortise and tenon structure can be adopted, that is, the inner pile and the outer pile cannot complete the mutual clamping connection method by themselves, but need to jointly form a clamping and limiting relationship among three components with at least one external connecting member. For example, a groove is used to wrap two enlarged ends, and only by embedding the two enlarged ends into the groove can a clamping relationship be formed.

[0028] The other way is the one mentioned in this embodiment, that is, either the inner pile or the outer pile has a complete clamping structure, which is only used as a connecting body between the two side plate bodies, and the other part of the split connecting pile can provide some additional functional uses, such as sound insulation and heat preservation, by increasing the thickness or other means.

[0029] Combined with the sixth implementation manner of the first aspect, the present invention provides a ninth implementation manner of the first aspect. A plurality of connecting piles are stacked along the length direction. At least one through strengthening hole is provided along the length direction of the connecting pile. Adjacent connecting piles are limited and connected by a strengthening rib passing through the through strengthening hole.

[0030] The connecting pile is used to connect the plate body, and the plate body can be a structure formed by stacking several base plates with different lengths or heights adjusted. In order to cooperate with the characteristics of quick disassembly, quick assembly, convenient transportation and carrying of prefabricated buildings, the connecting pile is also set as a stacked structure, that is, a plurality of connecting piles are stacked along the length direction, and then a whole is formed by passing through and connecting all the connecting piles with a strengthening rib.

[0031] Combined with the ninth implementation manner of the first aspect, the present invention provides a tenth implementation manner of the first aspect. When the split connecting piles are stacked, a strengthening piece is provided between several split connecting piles that constitute a single columnar structure, and the strengthening piece has a through hole for the strengthening rib to pass through.

[0032] In the second aspect, the present invention also provides a structure, which adopts the combined wall panel in several implementation manners of the first aspect above. The combined wall panel includes a side wall and a top wall formed by wall panels. The base plate includes a top plate forming the top wall and side wall plates forming the side wall. The connecting piece includes a top connecting piece connecting the top plate and a side plate connecting piece connecting the side wall plates; the side wall and the top wall are tightly fixed and connected by a screw passing through and contacting the top plate and the side wall plate.

[0033] Combined with the second aspect, the present invention provides a first implementation manner of the second aspect. After the top plate is connected to the top connecting piece, a water leakage hole extending along the nesting direction of the top plate and the top connecting piece is formed at the connection. The water permeable hole communicates with the external environment on two side surfaces of the top wall.

[0034] In the third aspect, the present invention also provides a structure, which adopts the combined wall panel in the fifth implementation manner of the first aspect above. The combined wall panel includes a side wall and a top wall formed by wall panels. The base plate includes a top plate forming the top wall and side wall plates forming the side wall. The connecting piece includes a top connecting piece connecting the top plate and a side plate connecting piece connecting the side wall plates; the side wall and the top wall are fixedly connected at the edge;

[0035] The plate bodies of the top wall are connected to each other through the top connecting piece, and the plate bodies of the side wall are connected through the connecting pile.

[0036] Combined with the third aspect, the present invention provides a first implementation manner of the third aspect. The connecting pile includes a direct connection pile and a corner connection pile. The corner connection pile connects two groups of plate bodies with a non-zero included angle, and the corner connection pile connects at least two groups of mutually parallel plate bodies.

[0037] Combined with the first embodiment of the third aspect, the present invention provides a second embodiment of the third aspect. The corner connection pile adopts a split connection pile, including a corner outer pile and a corner inner pile that are clamped and limited to each other. There are two connection grooves on the corner inner pile as clamping structures for nested connection with the side plate connectors, and the corner outer pile has a number of strengthening holes as strengthening holes.

[0038] Combined with the first embodiment of the third aspect, the present invention provides a third embodiment of the third aspect. The direct connection pile adopts a split connection pile, including a side inner connection pile, a side inner pile, and a side outer pile that are clamped and limited to each other;

[0039] The side outer pile and the side inner pile are connected and combined to form a direct connection pile for connecting two groups of parallel plates;

[0040] The side outer pile and the side inner connection pile are combined to form a direct connection pile for connecting three groups of plates, where two groups of plates are parallel to each other.

[0041] The beneficial effects of the present invention are as follows:

[0042] (1) Through the plate structure composed of double-layer substrates provided by the present invention, it is not only convenient for installation and disassembly, but also can set the materials and styles of the inner and outer substrates according to needs, that is, the replacement of the substrates of different orientations in the internal and external environments achieves different functional requirements;

[0043] (2) Through the same connector structure, the present invention can not only realize the mutual clamping and limiting between the substrates constituting the same plate body, but also realize the edge connection between adjacent plate bodies, with lower manufacturing cost, convenient installation, high efficiency, and convenient transportation;

[0044] (3) By providing a connection pile structure as an intermediate connector for the wall panel, the present invention can not only improve the connection stability, mainly as a load-bearing main body, but also provide a structure for attaching and supporting on both sides of the wall panel, thus avoiding the problem of poor hanging performance caused by insufficient structural strength of the substrate structure;

[0045] (4) Through the design of various split and integrated connection pile structures, the present invention cooperates with the connectors to form various forms of corners and connection transitions to meet different needs. At the same time, through the stacking setting method and the through strengthening rib structure, it can maintain sufficient structural strength while realizing modular structure design, and adaptively install according to the corresponding number of connection pile structures matching different wall panel heights;

[0046] (5) The structure of the structure formed by the wall panels in the present invention is divided into side walls and top walls. According to different functional requirements, the side walls are connected by connecting piles, while the top plates are directly connected by connecting pieces, so as to provide corresponding structural assembly according to the different wall characteristics of the structure, maintain the modular assembly design of the smallest unit while meeting the functional requirements, facilitate transportation, and improve the disassembly and assembly efficiency;

[0047] (6) The present invention directly tightens the side walls and the top walls through screws, further improving the structural stability and the convenience of disassembly and assembly. Leakage holes are formed through the gaps between the connecting pieces and the connecting structures in the top plates, facilitating the water vertically falling on the surface of the top wall to enter the leakage holes from the gaps between the top plates and flow to both sides, achieving a drainage effect.

Detailed implementation manners

[0068] The following further explains the present invention in conjunction with the drawings and specific embodiments.

[0075] Embodiment 1:

[0076] This embodiment discloses a combined wall panel for prefabricated buildings. The wall panel can be set independently as a wall structure, or several combined wall panels can be surrounded to form a semi-closed or closed structure. The feature is that through a novel combined structure design, the corresponding number of base materials can be prefabricated according to requirements and quickly assembled and formed on site.

[0077] Specifically, the combined wall panel is composed of several groups of plate bodies connected by sides, and each plate body is composed of at least two base plates. Among them, the adjacent plate bodies are connected by groove snap connections through the provided connecting pieces, and the two base plates forming the same plate body are also connected by snap connections through the connecting pieces.

[0078] Regarding the connection between the plate bodies, the plate bodies can be regarded as a whole sheet material. Each side of the plate body has a groove structure. The connecting piece is an intermediate structure between two plate bodies and has an end corresponding to the groove structure. The connection between the plate bodies is realized by fitting and clamping the end of the connecting piece with the groove structure of the plate body.

[0079] Each plate body is formed by snap - connecting two substrate surfaces. In this embodiment, in order to meet the requirements of modularization and unified base materials required for prefabricated buildings, the substrates used are all of the same standard. As a result, the groove structure of the plate body is formed by the cooperation of two substrates.

[0080] Therefore, the same connecting piece has two sets of ends. Each set of ends is respectively connected to two substrates that are abutted against each other. The same connecting piece can not only connect the substrates but also connect adjacent plate bodies. In essence, it is through two sets of oppositely arranged ends that are respectively connected to two sets of substrates of two adjacent plate bodies, which can not only provide a limiting force perpendicular to the substrate direction but also provide a limiting force parallel to the substrate surface between adjacent plate bodies.

[0081] Furthermore, the substrate is a rectangular structure. The substrate has two main oppositely arranged surfaces. By providing a snap - connection structure on one side surface that forms a snap - connection with the connecting piece, the substrate is divided into an inner side surface and an outer side surface. At least two substrates forming the same plate body are arranged with their inner side surfaces facing each other and fitting together. The connecting piece is arranged between the two substrates and is respectively connected to the snap - connection structures of the two substrates.

[0082] In this embodiment, the so - called snap - connection structure includes a snap - connection relationship formed by elastic deformation and a nested connection relationship realized through a groove connection structure. The snap - connection method realized by elastic deformation can provide a limiting force by setting a sufficiently large elastic structure, such as a spring clamp, etc. However, this structure is only applicable to temporary structures that require high - frequency disassembly and assembly. In this embodiment, it is only briefly described as a feasible method. The following content will be described with a more stable and equally convenient disassembly and assembly fixed - type groove connection structure.

[0083] Specifically, the end of the connecting piece and the connection structure of the substrate is a groove connection structure, that is, a special - shaped groove structure. The subordinate concepts include a T - shaped groove or a dovetail groove. In this embodiment, it is not limited to the specific characteristics of the groove connection structure, and the effects achieved are basically the same. It should be noted that, as a common cooperation and limitation between protrusions and groove structures in the field, it is not limited to the specific setting position. That is, in one way, the connecting piece is provided with a groove structure and the substrate is provided with a protrusion structure. In another way, which is detailed in this embodiment, the connecting piece is provided with a protruding end that can be slidably inserted into the groove structure on the inner side surface of the substrate.

[0084] This groove connection structure needs to run through the entire substrate, and openings are provided at two opposite edges of the substrate. The strip-shaped connecting piece is inserted into the opening of the groove structure on one side of the substrate for sliding fit, thereby providing a limiting effect in any direction with a non-zero angle with the sliding connection direction.

[0085] The same plate body can be composed of two groups of relatively arranged and stacked substrates, and several substrates are stacked, and the openings of the slot structures are aligned to form a slot structure connected along the stacking direction. The two groups of penetrating and corresponding slot structures of the same plate body share a connecting piece, that is, at least two opposite sides of the same plate body are penetrated by a connecting piece, and the two connecting pieces extend out of the plate body to form ends connected to the slot structure of another plate body.

[0086] In this embodiment, a plurality of stacked substrates are provided with concave-convex grooves on the side edge surfaces where the stack contacts, and adjacent substrates are fitted together to form a limit, and the limit force is perpendicular to the substrate surface to limit the relative movement of the two substrates. When adjacent plates are directly connected and fitted together through a connector, the limit can also be achieved by providing corresponding concave-convex grooves.

[0087] Furthermore, the cross section formed by cutting the strip-shaped connector from the side or perpendicular to the length direction is defined. The cross section of the connector in this embodiment is quasi-H-shaped, that is, it includes a middle connecting portion and first enlarged ends symmetrically arranged on both sides, the first enlarged ends are used to form ends connecting adjacent plates, and each first enlarged end has two ends, each of which is provided with a second enlarged end. Each substrate is provided with a connecting groove 13 for accommodating the second enlarged end to slide in and form a clamping limit, and the installation of a single-side substrate of a single plate body is achieved by aligning the second enlarged end along one end of the same connector and sliding it into the opening of the connecting groove 13.

[0088] Furthermore, in the present embodiment, both the first enlarged end and the second enlarged end are T-shaped structures, that is, the cross-section of a single connecting piece presents four symmetrically arranged T-shaped ends.

[0089] Furthermore, according to the different requirements for the structural strength of the wallboard, this embodiment adopts two types of panel connection methods. One is a lightweight wallboard with low connection strength, that is, all panels constituting the wallboard are connected by connecting pieces. The other is a wallboard with high connection strength, in which the panels are connected by connecting piles provided between the panels, and the connecting piles have at least two connecting grooves 13, which are used to correspond to the connecting pieces protruding from the panel on one side.

[0090] The connecting piles are divided into corner connecting piles and straight connecting piles according to their installation positions. Among them, the corner connecting piles are used for the wall panel structure at the corner, connecting two groups of plates with a spatial angle and the angle not being zero, so as to form a corner with a fixed angle. The straight connecting piles are used as the structure for connecting parallel plates in the whole flat wall panel. In some embodiments, for the flat wall panel structure, the connection method between the plates can be selected according to needs, that is, referring to Figure 2 the isometric view of the structure of the building in it, and two connection methods, namely, a single connector and a connecting pile, are used simultaneously between the same wall panels on the side to achieve connection.

[0091] Furthermore, the connecting piles are divided into integral connecting piles and split-type ones according to their shapes. Referring to Figures 11 - 18 , the figure shows the connecting pile structures of two shapes.

[0092] Among them, for the integral connecting piles, according to different installation positions, two symmetrically arranged connecting grooves 13 and two vertically arranged connecting grooves 13 are respectively provided. At the same time, according to the functional requirements of different inner and outer end faces, a flat and thick surface can be formed on the inner end face, that is, an integral double-connecting pile, which can provide a fixed point for punching and mounting equipment. Or an additional connecting groove 13 is provided to form an integral triple-connecting pile, which can connect three groups of plates, so as to form a plate partition inside the building structure. And on the outer side, an enlarged cavity is provided for inserting and arranging reinforcing bars or thermal insulation materials, so as to improve its structural strength or thermal insulation and sound insulation performance.

[0093] Among them, the split-type connecting piles also include two installation positions, namely, corner and straight connection, according to different installation positions. The split-type connecting piles include an outer pile and an inner pile. The split-type connecting piles have at least two connecting grooves 13. There are two ways to form the connecting grooves 13. One way is that the outer pile and the inner pile respectively have partial structures of the connecting grooves 13, and only when combined can a complete connecting groove 13 be formed. The other way is that the inner pile has two or more complete connecting grooves 13, and the outer pile is used as a reinforcing structure and a thermal insulation structure to be combined with the inner pile. Referring to Figure 17 and Figure 18 . The split connecting piles are connected by a groove connection structure provided additionally. During installation, after the inner pile and the outer pile are connected to each other, they are then connected in cooperation with the connectors on both sides.

[0094] In this embodiment, the connecting piles can adopt the stacking setting method of multiple pieces the same as the base plate to reduce the length of the whole connecting pile, which is convenient for transportation and flexible layout requirements. Among them, a number of reinforcing holes 10 are provided along the length direction of each connecting pile. The reinforcing holes 10 in this embodiment include Figure 11For the circular holes and square holes shown, after multiple connecting piles are stacked, the structural strength is enhanced by the reinforcing bars within the circular holes and square holes that penetrate all the connecting piles. Bolts can be provided for locking and fixing at both ends of the reinforcing bars, or bolts can be provided for locking and fixing at the joints between adjacent connecting piles.

[0095] It should be noted that steel bars with a cross-sectional diameter similar to that of the circular holes can be directly inserted into the circular holes as reinforcing bars, while rectangular steel is provided as the reinforcing bar in the rectangular holes, and heat-insulating materials are filled in the rectangular steel to improve its heat-insulating and sound-insulating effects.

[0096] Furthermore, in the solution where multiple connecting piles are stacked to form a strip structure, to enhance the structural strength of the split connecting piles, referring to Figure 17 and Figure 18 , a reinforcing sheet that completely covers the surfaces of the two adjacent connecting piles on both sides is also provided between two adjacent connecting piles. According to different installation positions, it is divided into a corner reinforcing sheet 17 and a straight connecting reinforcing sheet 18.

[0097] The reinforcing sheet structure is made of a metal material or other sheet materials with relatively high structural strength. Reinforcing holes 10 are reserved on the reinforcing sheet to facilitate the penetration of the reinforcing bars. In this embodiment, no connecting grooves 13 are provided on the reinforcing sheet, that is, the corresponding number of reinforcing sheets is set according to the length of the connecting piece, so as to form a multi-segment connecting groove 13 structure on a single connecting pile.

[0098] This embodiment also provides a structure, referring to Figures 1 - 10 , which is formed by enclosing with the above wall panel structure. The structure includes side walls that are vertically arranged on the ground and enclose to form a circular enclosure, and a top wall that is perpendicular to the side walls and covers and shields the upper part of the circular enclosure. Among them, several groups of connection structures of screws and bolts are respectively provided on the side edges where the top wall is connected to the side walls for edge connection, and fixation is formed by inserting screw structures into the ground at the bottom of the side walls.

[0099] Among them, the base plate includes a top plate 1 that constitutes the top wall and side wall plates 3 that constitute the side walls, and the connecting pieces include a top connecting piece 5 that connects the top plate 1 and a side plate connecting piece 7 that connects the side wall plates 3; the edges between the side walls and the top wall are fixedly connected; the plates of the top wall are connected to each other through the top connecting piece 5 and intermediate connecting pieces 6 provided between the base plates of the same plate, and the plates of the side walls are connected by connecting piles.

[0100] The connecting piles include straight connecting piles and corner connecting piles. The corner connecting piles connect two groups of plate bodies with a non-zero included angle, and the corner connecting piles connect at least two groups of parallel plate bodies.

[0101] The corner connection pile adopts a split connection pile, including a corner outer pile 4 and a corner inner pile 9 that are clamped and limited to each other. Two connection grooves 13 are provided on the corner inner pile 9 as clamping structures for nested connection with the side plate connector 7. The corner outer pile 4 has a number of reinforcing holes 10 as the reinforcing holes 10.

[0102] The direct connection pile adopts a split connection pile, including a side inner connection pile 8, a side inner pile 12 and a side outer pile 2 that are clamped and limited to each other; the side outer pile 2 and the side inner pile 12 are connected and combined to form a direct connection pile for connecting two groups of parallel plates; the side outer pile 2 and the side inner connection pile 8 are combined to form a direct connection pile for connecting three groups of plates, where two groups of plates are parallel to each other.

[0103] After the top plate 1 is connected to the top connector 5, a water leakage hole extending along the nested direction of the top plate 1 and the top connector 5 is formed at the connection. The water permeable hole communicates with the external environment on two sides of the top wall.

[0104] Further, referring to 11- Figure 18 , which shows several special integral connection pile structures.

[0105] Among them, referring to Figure 11 and Figure 12 , the structure of the integral corner pile 14 is shown. Referring to Figure 6 and Figure 9 , it can be seen that the split corner pile includes a corner inner pile 9 and a corner outer pile 4, and the groove connection is realized through a connector. Due to the split structure, in order to improve its structural strength, a corner lock groove 11 is also provided at the external connection of the two corner outer piles 4. The cross-section of the corner lock groove 11 is shown in the figure and is of a similar H shape, and the connection strength is enhanced by the structure inserted into the corner lock groove 11.

[0106] The integral corner pile 14 structure does not require disassembly and assembly, so more hollow areas can be set, that is, reinforcing holes 10 with larger cross-sectional dimensions can be set, and larger thermal insulation and sound insulation materials or thicker reinforcing structures can be filled in.

[0107] Referring to Figures 13 - 14 , the integral triple pile 15 is shown, which has three connection grooves 13 distributed in a T shape with three perpendicular opening directions, and can connect the side wall panels 3 on both sides and the inner wall panel in the middle. It has higher structural strength compared to the split structure.

[0108] Referring to Figures 15 - 16 , the integral double pile 16 is shown, that is, it has two connection grooves 13 with opposite openings.

[0109] Referring to Figures 17 - 18, is a special structure of the corner outer pile 4 and the corner inner pile 9. That is, the original way of splicing two corner outer piles 4 through connectors is converted into a corner inner pile 9 structure with two independent connecting grooves 13, and the corner outer pile 4 is fixed as a strengthening structure on the outer side of the corner inner pile 9. The splicing method is more convenient and the structural strength is greater. In this way, since the corner outer pile 4 and the corner inner pile 9 are divided into several sections in the vertical reverse direction, splicing can be achieved. For connection and structural strengthening, a corner strengthening piece 17 is provided in the middle, so as to improve the structural strength by arranging intervals in the middle.

[0110] It should be noted that referring to Figure 4 the structure, the specific dimensions are not limited in the figure. In this embodiment, it is mainly described in detail with respect to the structure of the building. However, in actual applications, this structure can also be used as a model toy. By adjusting its dimensions and materials, a structure similar to building blocks can be formed, which can be used for the educational building of children of a certain age group, so as to achieve the effect of guiding interests and developing intelligence, and can also be used as a display model.
