Description

[0001] A PANEL KIT FOR PANEL BUILDING ON-SITE ASSEMBLY

[0002] DESCRIPTION

[0003] Field of the invention

[0004]

[0001] The invention relates to the field of construction of buildings, in particular to the construction of residential buildings from panel elements of high factory readiness.

[0005] Background of the invention

[0006]

[0002] A delay of construction schedule has become one of the main concerns in construction industry, especially in developed countries where labor cost is expensive. In order to finish construction project within schedule and budget, without inquiring any additional costs, the construction industry has made several efforts and attempted a number of methods reducing building construction time. One approach to addressing these challenges involves the use of prefabricated components, such as panels, for building construction, or even integral modules that constitute a significant portion of the structure.

[0007]

[0003] Building systems known from the prior art often face challenges related to structural integrity and adaptability to different architectural designs. Current modular construction methods typically require significant on-site work to integrate electrical wiring, heating, plumbing, and other communication systems. This results in extended construction times and increased labor costs.

[0008]

[0004] Existing modular construction systems often depend on complex assembly methods, parts that are difficult to transport, and cumbersome mounting techniques involving key elements, screws, bolts, or non-symmetric interlocking panel portions. Furthermore, the dimensions of buildings constructed with such systems are constrained, as the overall size is typically limited by the capacity of transportation vehicles.

[0009]

[0005] Another disadvantage of modular buildings is the complexity involved in their deconstruction. Due to the large number of detailed components and preinstalled systems, disassembling a panel structure is a challenging and time-consuming process. This complexity makes it nearly impossible to transport the building to another location without incurring substantial material losses. The intricate connections and integrated systems mean that parts of the building may be damaged or rendered unusable during the disassembly process, leading to increased waste and diminished economic viability for relocation or reuse.

[0010]

[0006] US Patent US 6,931,803 Bl discloses a system for modular building construction that contains a plurality of extruded plastic beams that are stacked and interlocked using a tongue and groove interengagement. Plastic connecting components are provided for interlocking the horizontal beams to a vertical column. A drawback of this system is the wide variety of elements, which differ in type and use different fastening systems. Additionally, it does not offer a solution for the structural integration of wall structures with floor and roof structures, leading to potential challenges in achieving a unified and stable construction.

[0011]

[0007] US Patent No. US 10,829,929 Bl discloses a system and method for the alignment, interconnection, and installation of structural insulated panels in on-site building construction. The system consists of a set of panels with channels that are interconnected and aligned using vertical and plate splines. Unlike traditional methods, this system eliminates the need for fasteners like screws or nails. However, a significant drawback of this system is that in some areas, the panels fail to provide the necessary load-bearing capacity due to the multiple elements that weaken the structure. Additionally, the spline-based interconnection requires numerous individual components to be transported to the construction site, complicating the process.

[0012]

[0008] US Patent application No. US 2004 / 182035 Al discloses an interlocking partition and panel system that consists of interlocking components designed for the on-site assembly of frames that securely hold panels made of any solid material or fabric. The system allows for customized, temporary or permanent partitioning to be achieved quickly and cost-effectively, making the system adaptable to diverse construction needs. This system has limited application, as it can only be used to create walls and partitions.

[0013]

[0009] A preconfigured set of panels for panel buildings, including floors, walls, ceiling, having a complete range of components with all systems and preinstalled equipment, is preferred due to its reduced costs, the higher quality achievable compared to performing similar work on an outdoor construction site and due to constructional variability of the ready building. The present invention addresses the shortcomings of modular or panel buildings known in the prior art by offering a more efficient and practical solution to the existing problem, by introducing panels for building constructions having different types of connectors that are simple in their assembly. It provides an optimized approach for the on-site assembly and disassembly of wall, floor, comer, and ceiling panels of various dimensions, configurations, and materials, resulting in a building that is ready for occupancy within a matter of days. A building constructed from panels is not limited by its dimensions, as the use of panels allows for the construction of structures of any size. This approach provides greater flexibility in design and scalability, enabling the creation of buildings that can be tailored to specific size requirements without the constraints typically imposed by other construction methods. The result is achieved with minimal additional work due to the incorporation of connectors in the design of each of the panels of the panel building. These connectors simplify the process, ensuring that panels can be quickly and securely joined or separated, enhancing both the speed and flexibility of construction and deconstruction activities.

[0014] Summary of the invention

[0015]

[0010] The aim of the invention is reached by designing panels of high factory readiness for panel building that comprise connectors and joints providing fast assembly or disassembly of the same. The panels are prefabricated wall, corner, floor, ceiling and roof panels with integrated electrical wiring, heating, plumbing, and other communication systems necessary for fully operational building. The connectors and joints used in the present invention do not restrict the use of materials for production of panels.

[0016] [Oil] The present invention discloses five types of prefabricated panels for wall, corner, floor, ceiling and roof construction. The wall panel of the present invention is an elongated, rectangular wall panel. The wall panel has an interior face and an exterior face, spaced apart from the interior face, two side edges, where each side edge extends between the interior face and the exterior face throughout the entire height of the wall panel, and a top edge and a bottom edge. The interior and the exterior faces are the widest faces compared to the side edges and the top and the bottom edge. The bottom edge is the edge on which the wall panel is supported on the base of the panel building. The base of the panel building can be either a foundation or the floor panel of the building. The top edge is the edge on which a ceiling panel and a roof may be supported.

[0017]

[0012] The corner panel is an integral panel having two parts that are indivisibly joint at a right angle during the manufacture process, therefore forming a comer part of the corner panel. Each part of the corner panel has an interior face and an exterior face, spaced apart from the interior face, side edges faced away from the corner part of the corner panel, where the side edges extend between the interior face and the exterior face throughout the entire height of each part of the corner panel, and a top edge and a bottom edge. The interior and the exterior faces of each part of the comer panel are the widest faces compared to the side edges and the top and the bottom edges. The bottom edge is the edge on which the corner panel is supported on the base of the panel building. The top edge is the edge on which a ceiling panel and a roof may be supported.

[0018]

[0013] The bottom edge of the wall panel and the corner panel has a T-type connector extending along the entire length of the bottom edge in the longitudinal direction. In cross-section, the T-type connector is configured to resemble the letter "T". The T-type connector is characterized by a rectangular protrusion directed towards the floor panel or the base of the building.

[0019]

[0014] The top edge of the wall panel and the corner panel has a Il-type connector extending along the entire length of the top edge in the longitudinal direction. In cross-section, the Il-type connector is configured to resemble a reversed Greek letter "II". The Il-type connector is characterized by an angular protrusion, having a vertical section and a horizontal arm connected under a right angle. The angular protrusion is directed towards the roof of the building. The horizontal arm of the angular protrusion of a Il-type connector is directed towards the interior of the panel building.

[0020]

[0015] The cavity of the Il-type connector is also configured to facilitate the connection of electrical wiring throughout a building. Wiring cables are routed through a cable channel, which is integrally arranged within the cavity of the Il-type connector. Standard terminal blocks and wiring connectors, as known in the prior art, are employed for the connection. The wiring from two different wall panels is directly connected and housed within a specially designed, enclosed space beneath the wall-mounted rack. This arrangement allows for easy access and repair in the event of a fault, enhancing both maintenance efficiency and system reliability.

[0021]

[0016] Each of side edges of the wall panel and the comer panel has a vertically aligned groove of a tapered profile, that is narrow at the outermost part of the side edge of the wall panel and the comer panel, and becomes progressively wider as it goes deeper into a body of the panel. The said groove is adapted to receive a X-type joint suitable for inteijunction of multiple wall panels and / or comer panels. In other embodiments the said groove is in the shape of a reversed dovetail, or is of a T-type groove. The widest section of the T-type groove is oriented towards a body of the wall panel or the corner panel. This design ensures that the broader portion of the groove faces inward, allowing for secure connections.

[0022]

[0017] The floor panel is an elongated rectangular panel having a frame along its perimeter. The frame of the floor panel has a recess configured to engage with a corresponding protrusion located on the bottom edge of the wall panel and the corner panel. The number of sides of the frame of the floor panel equipped with the recess varies from one to four, depending on the number of walls or comers to be connected with the floor panel. The sides of the frame of the floor panel that are faced towards the interior of the building do not have a recess, but instead a H-type metal connector that is employed to facilitate the interjunction of multiple floor panels inside the perimeter of the panel building. In cross-section, the H-type connector is configured to resemble the letter "H". The connector is made of metal, however, other embodiments known in the prior art are allowable.

[0023]

[0018] The present disclosure introduces the X-type j oint designed for an interjunction of multiple wall panels and / or the comer panels. Said connector is formed as beam of a cubic or rectangular cross-section having four side faces, a top edge, and a bottom edge. The X-type joint on each of its faces has a vertically aligned, tapered protrusion that is wide at its outermost part and becomes gradually narrower towards the body of the beam, designed to fit precisely into the grooves of the wall panel for secure and efficient assembly. The form of the protrusion corresponds to the form of the groove on the side edges of the wall panel and the comer panel.

[0024]

[0019] The choice of materials for the X-type joint is influenced by its design. Joints having tapered protrusions may be entirely made from solid wood, though other material combinations are also considered. For these joints, alternative materials such as wood or insulation may be used internally, with an external metal covering. Conversely, for joints having dovetail or T-type profile protrusions, the protrusions as well as the external part of the beam must be constructed from metal to withstand structural loads; however, the internal material of the beam may be made of wood, but is not limited to it. This ensures the required load-bearing capacity while allowing for diverse material options for the joint's body.

[0025]

[0020] The protrusions of the X-type joint might be covered with casings having a groove identical to that the wall panel and the comer panel has on their side edges. The casings are designed to cover protrusions that are not utilized for wall connections. This allows for the addition of extra walls and enables flexible building layouts, even in areas where walls were not originally planned, provided the floor panel includes a corresponding recess in its frame.

[0026]

[0021] The ceiling panel has an upper side facing towards the roof of the panel building, and a lower side facing towards the floor of the building, and four side edges facing towards the exterior of the building. Each of the side edges has a protrusion that forms an L-type recess on the lower side of the ceiling panel. The protrusion is intended for an engagement with the H-type connector of the top edge of the wall or the corner panels.

[0027]

[0022] The roof of the panel building, assembled using the panels disclosed in the present invention, is not restricted to any specific roof type. It may be flat, a hip roof, or of any other design, provided it incorporates a common feature for secure assembly. The roof comprises a frame running along its perimeter, with a protrusion extending continuously around the edge of the frame. The protrusion of the frame is placed in the outermost part of the frame that is facing towards the exterior of the building. Said protrusion is extending downwards and is designed to face the top edge of the wall panel and / or comer panels. The height of the protruding part is designed to match the height of the angular protrusion of the Il-type connector, while the width of the protrusion should be up to half the width of the wall panel.
