Also disclosed is a method for erecting one or more housing or storage structure in accordance with the modular building system.

There is disclosed a method of constructing a building, comprising installing: wall structure of the building, the wall structure comprising a panel having opposed skins and a core within which extends at least one cavity; and a ceiling structure of the building, such that the ceiling structure is adjacent the wall structure, and the wall structure bounds a space at a side of the space and the ceiling structure bounds the space at a top of the space, and such that: the space is sheltered and/or isolated from the elements; and/or lock-up is attained in respect of said space, the method further comprising: thereafter installing at least one service line through at least one said cavity of said panel and/or installing at least one service line which comprises at least one said cavity of that panel; and thereafter installing a roof structure of the building over the ceiling structure, wherein a connector is secured between the wall structure and the ceiling structure to form therebetween a connection which is such that the connector engages both the ceiling structure and at least one of the skins so as to direct, to the skin(s) engaged thereby, loading exerted by the ceiling structure, and wherein said at least one said cavity is accessed through said connector and/or through said ceiling structure, to install the service line(s).

A pipe shaft module and a method for mounting a pipe shaft module in a pipe shaft of a building, said pipe shaft module (1) comprising: —a pipe connection box (5); and—at least one pipe (7a, b, c) which is protruding into the pipe connection box (5) and which is provided to the pipe connection box such that it can slide along its length direction in relation to the pipe connection box, wherein said pipe connection box (5) comprises: —a pipe connection device (11) comprising at least one pipe connector (13a, b, c) for each pipe (7a, b, c) provided in the pipe shaft module (1), wherein said pipe connection device (11) is mounted within the pipe connection box (5) such that it can be moved within the pipe connection box (5) into at least two different positions where one position is a connection position in which the pipe connectors (13a, b, c) are positioned such that one pipe connector (13a, b, c) can be connected to each pipe (7a, b, c) of the pipe shaft module (1).

The present invention provides a modular wall assembly with prefabricated wires, comprising: a base and multiple modular wall frames. The base is provided with wires and extends out of the base, and at least one connecting groove and a plurality of convex rings are fixed on the base, and the connecting groove is provided with a plurality of conducting parts, and the conducting parts are in electrical communication with wires in the base. The modular wall frames are provided with wires, and comprising: at least one connecting stud, at least one upper connecting groove, a plurality of upper convex rings, a plurality of lower grooves, and a locking device. Through those structure, the workers can quickly build a wall with strength not much different from a normal wall, while also setting up the indoor devices by using the prefabricated wires in the modular wall frame.

Prefabricated wall panels simplify the constructive of building units and other structures. The prefabricated wall panels can include a set of conduits pre-installed within the wall panels that enable simplified installation and conduit routing within a building unit or structure. The set of conduits can include electrical conduit, plumbing conduit, HVAC conduit, networking conduit, fire alarm conduit, and fire sprinkler conduit. The prefabricated wall panels can include above-door cavities to assist with structure design and coupling conduits between prefabricated panels. The prefabricated panels can additionally include dual-headed fire sprinklers that enable one fire sprinkler conduit to spray into multiple rooms, reducing the overall number of fire sprinkler conduits required within a structure.

A construction system utilizes a post-and-beam structure that supports major gravity loads of a building in combination with prefabricated exterior and/or interior wall panels that are not required to support gravity loads beyond self-weight. Studs within the prefabricated wall panels are oriented such that a widest face thereof is other than normal to the wall surfaces attached thereto. Such an orientation of the wall studs reduces or eliminates thermal bridging in the structure without adding materials, thereby reducing embodied carbon and embodied energy content. The orientation of the wall studs also maximizes the available space within the wall panels to accommodate electrical and plumbing utilities and insulation material and utilizes the studs along their strong axis to resist lateral loads.

The invention provides a method of locating a position of an electrical fixture behind a panel by using an aperture cutting guide comprising a support plate and a guide tube having a longitudinal aperture. The support plate is formed with first holes and second holes. The selected second hole and the guide tube protruding through a cut-out of a panel are positioned at an axis of the fixture installation location. A hole cutting tool having a longitudinal rotatable element and a cutting member with cutting teeth is directed towards the cut-out. The rotatable element is movably received and guided by the tube's longitudinal aperture. An opening within the panel is cut by the cutting teeth, so that the guide tube is adapted to retain a proper orientation of the longitudinal rotatable element and to prevent the cutting teeth of the tool from drifting away from a predetermined orientation.

An article of manufacture is disclosed comprising a 3D-printed wall panel having an interior side and an exterior side. The exterior side comprises a textured surface formed by 3D printing the wall panel onto a textured form. In certain embodiments, the textured surface mimics at least one of natural stone, brick, and wood siding, and the medium printed onto the textured form is concrete. The interior side has 3D printed structural elements printed thereon designed to mimic conventional wood-stud framing in at least one of dimensions and spacing. A method for fabricating the 3D printed wall panel as described above is also disclosed.

A retail display table includes a table top with openings, and a modular display mat disposed over each opening. Each of the modular display mats is movable between a closed position in which it covers its respective table-top opening, and an open position in which it is lifted above the table top so that a cavity underneath the modular display mat is accessible. Also, each modular display mat has holes to accommodate a configuration of displayed items, and is removable and replaceable with another modular display mat having a different configuration of holes to accommodate a different configuration of displayed items. A retail display system may include such a retail display table, along with other modular retail fixtures such as display walls with modular display wall inserts and retail counter units with modular display mats interchangeable with those of the retail display table.

Systems and methods are described herein for a panelized building assembly. In one example, an assembly may include one or more of a first composite planar panel, and second composite planar panel, and a planar joining element. The first and second planar panels may include a core material sandwiched between two fiber-reinforced skin elements. Each of the panels may include a first block of fiber-reinforced material coupled to at least one of the skin elements, which may define two slots for receiving the planar joining element. In some cases, the planar joining element, when placed within the slots of two panels to be joined, may transfer a load between the fiber-reinforced material of the two panels. The resulting joint may form a water-tight and fire-retardant seal.
