Description

Technical Field

[0001] The present invention belongs to the technical field of prefabricated buildings, and particularly relates to a combined connection module and a combined plate structure for prefabricated buildings. Background Art

[0002] A prefabricated building refers to a building in which a large amount of on-site work in the traditional construction method is transferred to a factory. Building components and fittings (such as floor slabs, wall panels, stairs, balconies, etc.) are processed and manufactured in the factory and transported to the construction site, where they are assembled and installed on-site through reliable connection methods. Prefabricated buildings mainly include precast prefabricated concrete structures, steel structures, modern timber structures, etc. Because they adopt standardized design, factory production, assembly construction, information management, and intelligent application, they are representatives of modern industrial production methods.

[0003] Among them, the panel assembly building is assembled by precast large-scale internal and external wall panels, floor slabs, roof panels, etc., also known as a large panel building. It is the main type of fully prefabricated building in the industrialized building system. Panel buildings can reduce the structural weight, improve labor productivity, expand the usable area of the building, and enhance the earthquake resistance. The inner wall panels of panel buildings are mostly solid or hollow slabs of reinforced concrete; the outer wall panels are mostly reinforced concrete composite panels with thermal insulation layers, and can also be made of lightweight aggregate concrete, foam concrete or large-pore concrete to form wall panels with external finishes. Equipment in the building often adopts centralized indoor pipe fittings or cassette toilets, etc. to improve the degree of assembly. The key problem of large panel buildings is the joint design. Structurally, the integrity of the connection of components should be ensured (the main connection methods between panels are welding, bolt connection and integral connection with post-cast concrete). In terms of waterproof structure, the waterproofing of the joints of the outer wall panels, as well as the thermal treatment of floor joints and corners, etc. should be properly solved. The main disadvantage of large panel buildings is that they have great restrictions on the shape and layout of the building. The internal partition of large panel buildings with transverse load-bearing bays lacks flexibility (the interior of longitudinal wall type, inner column type and large-span floor type can be flexibly partitioned).

[0004] The main advantage of prefabricated buildings is that the modular production and processing method can improve the construction efficiency. In the existing technology, most prefabricated buildings need to reserve steel bar positions for casting connection on-site, and using this method cannot effectively reduce the construction period. At the same time, in order to adapt to different installation positions, most of the components of some prefabricated buildings use non-standard products, and special structures are provided at the connection parts for fixation. This method requires multiple sets of molds for casting and forming of precast parts. Not only the production cost is relatively high, but also due to the special structural design, the space occupancy rate of a single component is relatively high, the transportation is difficult, and the single transportation volume is small. Summary of the Invention

[0005] In order to solve the problems existing in the prior art, the present invention provides a combined connection module for prefabricated buildings and its combined plate structure. The module is made of natural materials or composite materials processed from multiple materials. The module board is composed of module plates, and the module board includes wall panels, floor bearing plates, etc.; it realizes building houses like building blocks. According to different uses, it can be used for rapid construction of various types of emergency houses such as rescue, as well as in conventional industrial and civil buildings.

[0006] The technical solution adopted by the present invention is as follows:

[0007] A combined connection module for prefabricated buildings, including module boards, a plurality of the module boards are spliced with each other to form a board surface, and further includes a connecting piece for connecting the module boards and forming the board surface.

[0008] A connecting piece for connecting and tightening adjacent module boards is arranged in the module board, and the connecting piece is arranged in a connecting hole opened in the module board.

[0009] The present invention is a plate structure for prefabricated buildings. As the most basic unit of a building, prefabricated plate structures and connection mechanisms are often used for on-site assembly in prefabricated buildings. Compared with the casting molding method of existing fixed structures, it can not only improve the assembly efficiency, speed up the construction progress, but also be adjusted according to actual needs, and can form various different forms of building structures.

[0010] The main problem of existing prefabricated buildings assembled with plates is that the existing connecting pieces cannot adapt to long-term use. At present, in order to cope with short-term use, some prefabricated buildings adopt connection structures that are easy to disassemble. However, due to improper later maintenance, the buildings formed have cracks at the joints before reaching the service life. If casting or other fixed connection methods are adopted, the high-efficiency advantage of prefabricated buildings will be lost.

[0011] The present invention provides a new plate module and a connection structure cooperating with the plate module. The module board, as the smallest unit, forms a whole wall by splicing with each other, and then the wall forms a single building structure. In order to connect adjacent module board structures and avoid affecting the integrity by setting them outside, at least two connecting holes are provided on the module board to accommodate the connecting pieces.

[0012] Since the module boards of the present invention can form a plate structure with a large area by splicing with each other, the module boards are tightened and fixed by connecting pieces. In order to improve the integrity, the same penetrating connecting piece is used to fix multiple module boards, and combined connecting pieces can also be used to facilitate installation.

[0013] Among them, the shape of the module board is not limited. Generally, it includes special quadrilateral structures such as squares and rectangles, and can also adopt regular polygon structures such as hexagons. Then, the connecting pieces are set according to the number of other module boards adjacent to the single module board, and at least one connecting piece is used to tighten and fix between two adjacent module boards in the same board structure.

[0014] Further, the connecting piece includes a steel cable. The steel cable is inserted into the corresponding module board, and a lock is used to tighten the end of the steel cable inserted into the inner wall of the sinking groove.

[0015] In the above solution, the connection holes adopted are through-hole structures that penetrate the entire module board, but generally are straight-hole structures to adapt to rigid straight connecting pieces. If the through connection holes are arc-shaped line structures, in order to adapt to this arc-shaped hole structure, a soft and bendable steel cable material can be used for connection, which can not only improve the conforming effect, but also meet the connection of the connection holes of multiple module boards to form a longer and multi-directionally bent spline curve. And even when the connection holes on the same module board are in the same plane, in at least two intersecting connection holes, the situation of the connecting pieces crossing may occur, and the soft steel cable can also be used for fixed connection, so it has high flexibility.

[0016] Further, the connecting piece is a screw. When the screw is inserted into the module board, a bolt is used to tighten the end of the screw inserted into the inner wall of the sinking groove.

[0017] Further, at least two cross-connected connection holes are provided in the module board, and a complete connecting piece is provided in one of the connection holes;

[0018] In the other connection hole, two connecting pieces are respectively provided on both sides of the cross-connection, and an avoidance piece for connecting the connecting pieces on both sides is provided at the cross-connection, and an avoidance hole for the complete connecting piece to pass through is provided on the avoidance piece.

[0019] Regarding the problems mentioned in the above steel cable solution, if rigid connecting pieces are used and the connection holes in a single module board are in the same plane, there will be a problem of cross-interference of the through-type connecting pieces in a single sinking groove, which will cause it unable to be installed. Because the thickness of a single module board is limited, and in order to ensure the connection effect, the cross-sectional area of the connecting piece for connection is at least guaranteed to reach a certain value, so the connection holes are generally set in the same plane to avoid affecting the entire module board structure.

[0020] To accommodate the installation of rigidly connected screw-type connectors, a structure of a relief member with relief holes is adopted at two intersecting connection holes. When the connector uses a screw, the relief member is a threaded sleeve, and a relief hole with a width greater than the cross-sectional radius of the screw is provided in the middle position thereof. Thus, when connecting two connectors, the other penetrating screw perpendicular to the intersection can pass through the relief hole.

[0021] Further, a sink is formed by inward depression on one side end face of the module plate. Connection holes with axes parallel to this end face and penetrating the module plate are provided on the inner wall of the sink. For each adjacent module plate correspondingly connected on a single module plate, connection holes are provided, and the adjacent module plates are connected by connectors arranged in the connection holes.

[0022] Further, a plurality of sinks are provided on the same side end face of the module plate. A plurality of connection holes are provided on a single module plate, and a sink is provided at the intersection of every two connection holes at the intersection point;

[0023] At least one screw penetrating two corresponding connection holes is provided in the sink, and a relief sleeve for connecting the screw ends of a corresponding set of connection holes is provided in the sink. A relief hole is provided in the middle of the relief sleeve, and the screw penetrating the entire sink in the sink passes through the relief hole.

[0024] The opening of the sink faces inward, while the opening of the connection hole faces the adjacent module plate. Each single sink communicates with a plurality of connection holes, and the specific number depends on the actual shape of the module plate.

[0025] For example, if the end face shape of the module plate is quadrilateral, a single sink on the same module plate communicates with four connection holes, and the included angle between adjacent connection holes is a right angle. Such a conventional plate shape includes an end face and side faces. The end face is the inner and outer surfaces with a larger area, while the side faces are four surfaces with a smaller area and in contact with adjacent module plates. Then the connection holes are provided corresponding to each side face. In this case, at least one sink is provided on each module plate, and four connection holes are provided. Each connection hole corresponds to an adjacent module plate, and then they can be connected by arranging strip-shaped connectors with a certain length in the connection holes. The corresponding sink is used to fix the end of the connector. That is to say, at least the same connector exists in the sinks of two adjacent module plates. By fixing the end of the connector with a fixing member, the function of tightening two adjacent module plates is achieved.

[0026] Or, the module plate structure is in a polygonal shape, such as a triangle, a hexagon, etc. other than a quadrilateral. Then, there are as many adjacent module plates as there are sides, and at least one connection hole for connection is provided corresponding to each adjacent module plate, and the end of the connector penetrating into the sink in the sink of each module plate is fixed.

[0027] The connecting holes are hole structures that penetrate the entire modular board. Since at least one connecting hole is provided for each adjacent modular board, and the included angle between the axes of the connecting holes between adjacent modular boards is not zero, there must be at least two intersecting connecting holes on each modular board. And the connecting holes may not be in the same plane, so the so-called intersection positions include actual intersection or projection intersection. In order to avoid opening multiple counterbores, setting a counterbore only at the intersection position of the axes of its two connecting holes can at least fix two penetrating connecting holes in the counterbore.

[0028] It should be noted that the so-called penetrating connecting hole refers to a through-hole structure that is continuous and open on two sides. Then, if a counterbore is provided at the intersection position, the ends of the connecting pieces connecting different adjacent modular boards can be fixed in the counterbore, thus saving processes, avoiding opening multiple counterbores, and improving integrity.

[0029] Furthermore, a hollowed-out area is provided on the modular board, and a light-transmitting plate for transmitting light is provided in the hollowed-out area.

[0030] Furthermore, the connection surface between the modular boards is designed with a concave-convex structure, and a tape is provided on the connecting end faces of adjacent modular boards.

[0031] A combined board structure is a planar structure composed of the above-mentioned combined connection modules, and a profile board for edge wrapping is provided on the side of the board surface. The connecting piece passes through the profile board and is fixed by a fastener.

[0032] Among them, the profile board includes various types, such as angle steel profiles, T-shaped profiles, etc. Fixing holes are provided on the side wall of the profile board corresponding to the connecting holes for the connecting pieces to pass through and be fixed at the ends. Since the profile board is used for edge wrapping, it is generally set at the corner position. The corners between the boards are generally right angles, so the inner angles of the angle steel profiles and T-shaped profiles are all adapted right angles.

[0033] Furthermore, window openings and door openings are formed on the board surface by adjusting the number of modular boards, and profile boards are provided on the sides of the window openings and door openings for edge wrapping.

[0034] The beneficial effects of the present invention are as follows:

[0035] The present invention is a building structure composed of prefabricated parts processed and compounded from various materials or board types formed by processing a single material. For the convenience of disassembly and assembly, all components are connected by detachable connecting pieces. Compared with the existing method of connecting adjacent boards by bolts or steel bars, the present invention combines and assembles the connecting pieces and the modular board structure, which can not only be quickly fixed but also has relatively stable connection strength. Then, using profile boards or strip boards as the connection structure between the combined board structures can also cooperate with the connecting pieces to achieve fixation.

[0067] Embodiment 1:

[0068] In prefabricated buildings, prefabricated plate structures and connection mechanisms are often used for on-site assembly. Compared with the casting and forming method of existing fixed structures, it can improve the assembly efficiency and speed up the construction progress. The main problem of existing prefabricated buildings with plate assembly is that the existing connectors 2 cannot adapt to long-term use. At present, some prefabricated buildings adopt detachable connection structures for short-term use. However, due to improper later maintenance, the joints of the formed buildings crack before reaching the service life. If casting or other fixed connection methods are used, the high efficiency advantage of prefabricated buildings will be lost.

[0069] This embodiment is specifically a combined connection module for a prefabricated building, including module plates 1. A plurality of the module plates 1 are spliced with each other to form a plate surface, and further includes a connector 2 for connecting the module plates 1 and forming a plate surface therewith; a connector 2 for connecting and tensioning adjacent module plates 1 is provided inside the module plate 1, and the connector 2 is arranged in a connection hole 4 opened in the module plate 1.

[0070] As Figure 1 shown, the module plate 1 adopted therein is a square plate structure. Four adjacent module plates 1 are provided around each module plate 1. Then, connection holes 4 are opened in each module plate 1 along two median line directions, and the two connection holes 4 communicate with each other at the center of the module plate 1. And in Figure 1 、 Figure 2 and Figure 3 it can be seen that the connector 2 adopted therein is a screw structure. And it includes a long screw and two short screws. Only part of the structure is shown in the figure, so the long screw and the short screws are used to refer to them. The actual long screw is a horizontal rod passing through a plurality of module plates 1, and the length of the short screw is equal to the side length of the module plate 1, and is used to connect the central positions of two vertically adjacent module plates 1.

[0071] This conventional plate shape includes an end face and side faces. The end face is the larger inner and outer surfaces, while the side faces are four smaller surfaces that contact the adjacent modular plate 1. The connection holes 4 are provided corresponding to each side face. Two connection holes 4 are provided, and each opening of each connection hole 4 corresponds to an adjacent modular plate 1. Then, they can be connected by providing a strip-shaped connecting member 2 with a certain length in the connection hole 4. And at least one same connecting member 2 exists in two adjacent modular plates 1. By fixing the end of the connecting member 2 with a fixing member, the effect of tightening the two adjacent modular plates 1 is achieved.

[0072] As Figure 4 shown, which not only shows the structure of the modular plate 1 with cross-shaped connection holes 4 in this embodiment, but also a hollowed-out area is provided on the basis of this modular plate 1. Thus, a large hollowed-out area is dug on the modular plate 1 to facilitate the setting of a transparent plate, thereby facilitating light transmission and increasing the light intensity inside the building.

[0073] However, because the connection hole 4 structure is provided in each modular plate 1, after the hollowed-out area is opened, the openings of the connection holes 4 remain on the inner surface of the hollowed-out area. Because a transparent plate structure needs to be set, the original long screw is also adopted as a short screw structure, and an enlarged cavity is directly provided at the opening of the connection hole 4, and the short screw is tightened and fixed by a bolt. Thus, a good fixing effect can be ensured without setting the avoidance sleeve 5 and the long screw.

[0074] In Figure 4 it also shows the structures of the modular plates 1 with and without the hollowed-out area, and the setting situation of the connection holes 4 of the two modular plates 1 can be seen in the perspective view part. And in Figure 6 it shows the state diagram of a partial combined plate body structure composed of this modular plate 1.

[0075] Embodiment 2:

[0076] This embodiment discloses a combined connection module for an assembled building, including a modular plate 1. A plurality of the modular plates 1 are spliced with each other to form a plate surface, and further includes a connecting member 2 for connecting the modular plates 1 and forming a plate surface therewith; a connecting member 2 for connecting and tightening adjacent modular plates 1 is provided in the modular plate 1, and the connecting member 2 is arranged in a connection hole 4 opened in the modular plate 1.

[0077] As Figure 5 shown, which shows the structure of the modular plate 1 in this embodiment. The difference from Embodiment 1 is that two mutually parallel connection holes 4 are provided in the horizontal direction, and a connection hole 4 extending along the midline is also provided in the vertical direction.

[0078] In this embodiment, the connectors 2 used include two types: screw rods and steel cables, and generally the screw rod structure is adopted. During installation, similar to Embodiment 1, first, the modular plates 1 in the same column are installed vertically. And in the vertically arranged connection holes 4, there are short screw rods and avoidance sleeves 5. Each avoidance sleeve 5 is located at the center of each modular plate 1, and the orientations of the avoidance holes 5.1 are the same, all facing the connection holes 4 on both sides. Then, the columns of modular plates 1 are connected and abutted against each other, and multiple horizontally arranged long screw rods are installed through them. Compared with Embodiment 1, two connection holes 4 are provided on each modular plate 1 in the horizontal direction, which can ensure a better stability effect.

[0079] And in Figure 5 and Figure 7 it also shows the structure of the modular plate 1 with a hollowed-out area opened on the modular plate 1 of this embodiment. When the hollowed-out area is arranged between two horizontally arranged connection holes 4, it can avoid affecting the installation of the connectors 2 in the horizontal direction. At the same time, on the modular plate 1 with the hollowed-out area, the avoidance sleeve 5 is not adopted, but the short screw rods on the upper and lower sides are directly fixed by bolts.

[0080] In Figure 8 and Figure 9 it respectively shows the schematic diagrams of the combined plate body structure formed by splicing the modular plates 1 of this embodiment. Among them, Figure 8 is a flat-top structure, and its top surface is also formed by splicing modular plates 1. And at the corner, profile plates or construction columns are provided for connection. Then, the connectors 2 of the two combined plate bodies connected at a vertical angle can fix their ends on the same profile plate or construction column through bolts, so as to achieve better connection stability. And in Figure 10 it shows a partial house structure formed by splicing with the combined plate body structure in this embodiment.

[0081] This embodiment is specifically a combined connection module for an assembled building, including modular plates 1. A plurality of the modular plates 1 are spliced with each other to form a wall surface, and it also includes connectors 2 for connecting the modular plates 1 and making them form a wall surface; a sink 3 is recessed inward on one end surface of the modular plate 1, and connection holes 4 with axes parallel to this end surface and passing through the modular plate 1 are provided on the inner wall of the sink 3. For each modular plate 1, the adjacent modular plates 1 corresponding to it are all provided with connection holes 4, and the adjacent modular plates 1 are connected through the connectors 2 arranged in the connection holes 4.

[0082] Among them, the modular plate 1 is used as the smallest unit, and forms an entire wall surface through mutual splicing, and then forms a single building structure from the wall surface. In order to connect the adjacent modular plate 1 structures and at the same time avoid affecting the integrity when it is set outside, at least one sink 3 and a plurality of connection holes 4 communicated with the sink 3 are provided on the modular plate 1 to place the connectors 2.

[0083] The opening of the sunk groove 3 faces inward, while the opening of the connecting hole 4 faces the adjacent modular board 1. Each single sunk groove 3 communicates with a plurality of connecting holes 4, and the specific quantity depends on the actual shape of the modular board 1.

[0084] As Figure 11 shown, if the end face shape of the modular board 1 is quadrilateral, then each single sunk groove 3 on the same modular board 1 communicates with four connecting holes 4, and the included angle between adjacent connecting holes 4 is a right angle. This conventional plate shape includes an end face and side faces. The end face is the larger inner and outer surfaces, while the side faces are four smaller surfaces that contact the adjacent modular board 1. Then the connecting holes 4 are arranged corresponding to each side face. In this case, at least one sunk groove 3 is provided on each modular board 1, and four connecting holes 4 are provided. Each connecting hole 4 corresponds to an adjacent modular board 1, and then they can be connected by arranging a strip-shaped connecting piece 2 with a certain length in the connecting hole 4. The corresponding sunk groove 3 is used to fix the end of the connecting piece 2. That is to say, at least the same connecting piece 2 exists in the sunk grooves 3 of two adjacent modular boards 1. By fixing the end of this connecting piece 2 with a fixing piece, the function of pulling tight two adjacent modular boards 1 is achieved.

[0085] A plurality of sunk grooves 3 are provided on the same-side end face of the modular board 1. A plurality of connecting holes 4 are provided on each single modular board 1, and a sunk groove 3 is provided at the intersection point at the intersection position of every two of the connecting holes 4. At least one connecting hole 4 is provided corresponding to each adjacent modular board 1, and the included angle between the axes of the connecting holes 4 between adjacent modular boards 1 is not zero. Then there will definitely be at least two intersecting connecting holes 4 on each modular board 1. The connecting holes 4 may not be in the same plane, and its so-called intersection position includes actual intersection or projection intersection. In order to avoid opening a plurality of sunk grooves 3, only setting a sunk groove 3 at the intersection position of the axes of its two connecting holes 4 can at least fix two penetrating connecting holes 4 in the sunk groove 3.

[0086] Embodiment 4:

[0087] This embodiment is a combined connection module for a prefabricated building. Its basic module is the modular board 1. As Figure 11 shown, a plurality of modular boards 1 are spliced with each other to form a wall surface. The modular board 1 has a square structure, and a connecting piece 2 for connecting and forming the wall surface is also provided between adjacent modular boards 1.

[0088] A sunk groove 3 is formed by inward depression at the central position of one side end face of the modular board 1. The sunk groove 3 is a circular blind hole structure. A connecting hole 4 with an axis parallel to this end face and passing through the modular board 1 is provided on the inner wall of the sunk groove 3. Each single modular board 1 is correspondingly provided with a connecting hole 4 for the adjacent modular board 1 to be connected, and the adjacent modular boards 1 are connected by the connecting piece 2 arranged in the connecting hole 4.

[0089] Among them, the connecting member 2 in this embodiment is a steel cable and a locking device. The steel cable is inserted into the corresponding module plate 1, and the end of the steel cable inserted into the inner wall of the sink 3 is tightened by the locking device.

[0090] Because in the above-mentioned Embodiment 3, the connecting hole 4 adopted is a through-hole structure that penetrates the entire module plate 1, but generally it is a straight-hole structure, so as to adapt to the rigid straight connecting member 2.

[0091] If the through connecting hole 4 is an arc-shaped line structure, in order to adapt to this arc-shaped hole structure, a flexible and bendable steel cable material can be used for connection, which can not only improve the conforming effect, but also meet the connection of the connecting holes 4 of multiple module plates 1 to form a long and multi-directionally bent spline curve. And even when the connecting holes 4 on the same module plate 1 are in the same plane, the situation where the connecting members 2 may cross in a single sink 3 may occur, and the flexible steel cable can also be used for fixed connection, thus having high flexibility.

[0092] Embodiment 5:

[0093] This embodiment is a combined connection module for an assembled building, and its basic module is the module plate 1. As Figure 11 shown, multiple module plates 1 are spliced together to form a wall surface. The module plate 1 is a square structure, and a connecting member 2 for connecting and forming a wall surface is also provided between adjacent module plates 1.

[0094] A sink 3 is formed by inward depression at the center position of one end face of the module plate 1, and the sink 3 is a circular blind hole structure. A connecting hole 4 whose axis is parallel to this end face and penetrates the module plate 1 is provided on the inner wall of the sink 3. For each adjacent module plate 1 corresponding to the connection on a single module plate 1, a connecting hole 4 is provided, and the adjacent module plates 1 are connected by the connecting member 2 arranged in the connecting hole 4.

[0095] Among them, the connecting member 2 is a screw rod. When the screw rod is inserted into the module plate 1, the end of the screw rod inserted into the inner wall of the sink 3 is tightened by a bolt. In this embodiment, two types of screw rod structures are provided. One is a long screw rod that penetrates the entire wall surface composed of the module plates 1, and the other is a short screw rod that connects two adjacent or multiple module plate 1 structures on the same straight line.

[0096] At least one screw rod penetrating through two corresponding connection holes 4 is provided in the sinking groove 3, and an avoidance sleeve 5 for connecting the end part of the screw rod corresponding to a group of connection holes 4 is provided in the sinking groove 3. An avoidance hole 5.1 is provided in the middle of the avoidance sleeve 5, and the screw rod penetrating through the entire sinking groove 3 in the sinking groove 3 passes through the avoidance hole 5.1. As mentioned in the above steel cable scheme, if a rigid connecting piece 2 is adopted and the connection holes 4 in a single module plate 1 are in the same plane, there will be a problem of cross influence for the penetrating connecting piece 2 in a single sinking groove 3, resulting in its inability to be installed.

[0097] In this embodiment, when setting the connection holes 4, they are generally set in the same plane to avoid affecting the structure of the entire module plate 1. In order to adapt to the installation of the screw-type connecting piece 2 with rigid connection, a structure of an avoidance sleeve 5 with an avoidance hole 5.1 is adopted in the sinking groove 3. The sleeve is a threaded sleeve with an avoidance hole 5.1 formed in the middle position, and the width of the avoidance hole 5.1 is greater than the radius of the cross section of the screw rod. Thus, when connecting two connecting pieces 2, the other penetrating screw rod perpendicular and intersecting with it can pass through the avoidance hole 5.1.

[0098] Embodiment 6:

[0099] This embodiment is a combined connection module for a prefabricated building, and its basic module is the module plate 1. As Figures 12 - 14 shown, a plurality of module plates 1 are spliced with each other to form a wall surface. The module plate 1 is of a square structure, and a connecting piece 2 for connecting and forming a wall surface is further provided between adjacent module plates 1.

[0100] A sinking groove 3 is formed by inward depression at the central position of one end face of the module plate 1, and the sinking groove 3 is of a circular blind hole structure. Connection holes 4 with axes parallel to this end face and penetrating through the module plate 1 are provided on the inner wall of the sinking groove 3. For each adjacent module plate 1 correspondingly connected to a single module plate 1, connection holes 4 are correspondingly provided, and the adjacent module plates 1 are connected through the connecting pieces 2 arranged in the connection holes 4.

[0101] In this embodiment, the module plate 1 is provided with four mutually perpendicular connection holes 4, and all are communicated with the sinking groove 3, so that the module plate 1 is divided into four square structures with equal areas by the axes of the connection holes 4 inside. And the connecting pieces 2 in this embodiment are all of the same kind of screw rod structure with the same length, and the length is greater than or equal to the sum of the lengths of two collinear connection holes 4 in adjacent module plates 1. That is to say, the screw rod length in this embodiment is only enough to connect the structures of two mutually attached module plates 1.

[0102] Moreover, since the axis of the connection hole 4 divides the entire module board 1 into four small square structures of equal area from the inside, when constructing the entire wall panel, there will be window openings left blank on multiple module boards 1 locally. In this embodiment, four small hollow areas are opened on a single module board 1 in the four small square areas divided, and a light-transmitting acrylic board or a light-transmitting board 6 made of glass is embedded in the hollow area. Then, multiple module boards 1 with hollow areas in the same area can not only increase the light transmittance but also will not block the light due to the internal connecting piece 2.

[0103] Embodiment 7:

[0104] This embodiment is specifically a combined connection module for an assembled building, and its basic module is the module board 1, as Figures 15 - 18 shown. Multiple module boards 1 are spliced together to form a wall surface, and at the same time, multiple wall surfaces form a building structure.

[0105] The module board 1 is a square structure, and a connecting piece 2 for connecting and forming a wall surface is also provided between adjacent module boards 1. Two sink grooves 3 formed by inward depressions are symmetrically arranged with the center as the origin on the vertical center line of one end face of the module board 1, and the sink groove 3 is a circular blind hole structure.

[0106] Two connection holes 4 with intersecting and perpendicular axes and passing through the module board 1 are provided corresponding to each sink groove 3, and the vertical directions of the two sink grooves 3 in the figure share one connection hole 4. That is, one connection hole 4 is provided along the vertical center line, and the connection hole 4 continuously passes through the inner walls of the two sink grooves 3. And one connecting piece 2 is provided corresponding to the openings of the four connection holes 4 in each sink groove 3, and the connecting piece 2 is used to connect adjacent module boards 1 or the adjacent sink groove 3 structures on the same module board 1.

[0107] Among them, the connecting piece 2 is a screw rod, and when the screw rod penetrates into the module board 1, the end of the screw rod penetrating into the inner wall of the sink groove 3 is tightened by a bolt. And in the connection holes 4 for connecting two adjacent sink grooves 3 on the same module board 1, a separate short screw rod does not need to be provided, but a through-type long screw rod is used for connection. And in the horizontal direction, short screw rods are used for connection, and the ends of the short screw rods in the sink grooves 3 can be connected and fixed by bolts or a relief sleeve 5 with a relief hole 5.1.

[0108] At the same time, a combined plate structure is formed by the above-mentioned multiple module boards 1, and a profile board for edge wrapping is provided on the side surface of the wall surface. As Figure 23 shown, it is a schematic diagram of two combined plate structures in this embodiment, one of which is a flat top structure design and the other is a pitched roof design.

[0109] Among them, the connecting member 2 passes through the profile plate and is fixed by fasteners. The end faces on one side of the sunken groove 3 are all oriented towards the inner side of the building, and after the building is formed, it is filled and covered with a plug made of rubber material. The connection surface between the module plates 1 is designed with a concave-convex structure, that is, a male-female groove structure, which can not only perform pre-positioning, but also prevent cracking between adjacent module plates 1 after being tightened by the connecting member 2. At the same time, in order to improve the connection stability and prevent relative rubbing, tapes are provided on the connecting end faces of adjacent module plates 1. Figure 20 Figure 2 shows a perspective view of a building formed by the combined plate structure, in which it can be seen that all the walls of the building are formed by the combined plate structure in this embodiment. At the same time, each combined plate structure is also connected by a profile plate, and mounting holes for connecting the connecting members 2 between adjacent two combined plate structures are provided on the profile plate.

[0110] As Figure 17 shown, in a single wall, window openings and door openings are formed by adjusting the number of module plates 1, and profile plates are provided on the sides of the window openings and door openings for edge wrapping.

[0111] The window opening is formed by dividing the module plate 1 into left and right two regions along the center line connecting the two sunken grooves 3 vertically on a single module plate 1. Hollow regions with the same area are provided in each region, and light-transmitting plates 6 made of acrylic material are provided in each hollow region.

[0112] Embodiment 8:

[0113] This embodiment is specifically a combined connection module for an assembled building. Its basic module is the module plate 1, as shown in Figure 19 , 21 and 22. Multiple module plates 1 are spliced together to form a wall surface, and at the same time, a building structure is formed by multiple wall surfaces. The module plate 1 has a square structure, and a connecting member 2 for connecting and forming a wall surface is also provided between adjacent module plates 1.

[0114] Four sunken grooves 3 formed by inward depressions are uniformly arranged on one end face of the module plate 1. The sunken groove 3 has a circular blind hole structure. The center line connecting two adjacent sunken grooves 3 only includes two directions, horizontal and vertical, so that a through-type screw can be used for connection. Each of the sunken grooves 3 in the figure is communicated with two groups of connection holes 4 with collinear axes, and the same connected connection hole 4 is provided between adjacent sunken grooves 3. A connecting member 2 is provided in each connection hole 4.

[0115] Among them, the connecting member 2 is a screw rod. When the screw rod penetrates into the module plate 1 and the end of the screw rod penetrating into the inner wall of the sinking groove 3 is tightened by a bolt. In the connecting hole 4 on the same module plate 1 for connecting two adjacent sinking grooves 3, a short screw rod does not need to be separately arranged, but a through-type long screw rod is used for connection. Horizontally, a short screw rod is used for connection, and the end of the short screw rod in the sinking groove 3 can be connected and fixed by a bolt or a avoiding sleeve 5 with an avoiding hole 5.1.

[0116] Meanwhile, a plurality of the above-mentioned module plates 1 form a combined plate body, and a profile plate for edge wrapping is provided on the side surface of the wall surface. The connecting member 2 penetrates through the profile plate and is fixed by a fastener. The connection surface between the module plate 1 and the module plate 1 is designed with a concave-convex structure, that is, a male-female groove structure, which can not only perform pre-positioning, but also prevent cracking between adjacent module plates 1 after being tightened by the connecting member 2. Meanwhile, in order to improve the connection stability and prevent relative rubbing, a tape is provided on the connecting end surfaces of adjacent module plates 1. As shown in the figure, in a single wall surface, window openings and door openings are formed by adjusting the number of module plates 1, and profile plates are provided on the sides of the window openings and door openings for edge wrapping.

[0117] Among them, the window opening is provided with a relatively large hollow area in a single module plate 1 within the single area formed by the central connection lines of the four sinking grooves 3, and a light-transmitting plate 6 made of acrylic material is provided in each hollow area.

[0118] It should be noted that in this embodiment, only the wall surface composed of the same module plates 1 is used as the top plate, and the top plate is arranged horizontally, but it can also be arranged obliquely. When arranged obliquely, two of the four vertical wall surfaces will be cut, so that the top plate presents an inclined state during installation.
