A construction element includes at least one module with a rectangular parallelepiped shape, hollow and made of a composite material. The module is delimited by an enclosure with four panels, two first opposing parallel panels and two second panels perpendicular to the first panels. The second panels include at least one groove parallel to the first panels. Each second panel is extended on one side by an L-shaped profile and on the other side by a flat profile. The profiles are elements protruding outwards, parallel to the groove.

The present disclosure relates to components and methods for a modular building system, used as mid-rise residential and office building, to pre-fabricate and assemble the system quickly, easily and simply. More particularly, it relates to a building temporal self-supporting panel system invention that includes formwork, structural rebars and insulated panels for the purpose of wall, floor and roof. The panel system is composed of a number of layers and a temporal-structural frame, integrating all constructive elements needed: temporal structural capacity, thermal and acoustical insulation, impermeability and pre-installations; designed considering operation, function, fabrication and assembling.

An object of the present invention is to provide a gypsum-based load-bearing board for wood structural load-bearing walls which is capable of increasing the co-efficient of effective wall length without additionally using reinforcement materials or stiffening materials, and without increasing the specific gravity and/or the thickness of the gypsum-based board. The gypsum-based load-bearing board (10) for wood structural load-bearing walls includes a main member or a core member formed from a board-shaped hardened gypsum containing an inorganic fiber and an organic-based strength enhancer that exert a lateral nail resistance of 500 N or more, and a paper covering at least front and back sides of the main member or the core member to constitute the load-bearing board. The load-bearing board has a surface density of 6.5 kg/m.sup.2 to 8.9 kg/m.sup.2, exhibits an ultimate displacement (?u2) of the load-bearing wall measured by an in-plane shear test of greater than 20?10.sup.3 rad (?u2), and exerts an ultimate strength (correction value) (Pu) of greater than 7.6 kN. According to the wooden structural load-bearing walls using the load-bearing board can obtain short-term reference shear strength (P.sub.0) greater than the wooden structural load-bearing walls using similar load-bearing board having a surface density of greater than 9.0 kg/m.sup.2.

Provided is a method of construction employing a prefabricated wall system. The method provides for assembly of the wall system on the construction site. Embodiments of the wall system and the methods of use thereof are provided for.

A system of structural interlocking panels for forming disaster-resistant buildings, comprising: a hollow, internally-braced, vacuum-insulated panel shell having at least two interlocking sides, the first side having a convex-inward single-curvature, the second side having a straight surface, the third side having a straight surface with at least one integral tongue with at least one head extending vertically-upward for receiving a complementary groove of a first side of an adjacent panel. Panels are thus vertically slide-locked along panel sides and faces, thereby triggering automatic snap joints that prevent backward movement of the panel. The system can assemble spheres, cylinders, toroids, tetrahedrons, flat shapes, and irregular shapes.

A wall panel includes a frame provided with vertical battens. The frame defines a plurality of holes. A connecting plate is formed by a mixture of a curable material in which organic plant-derived elements are embedded. The wall panel includes a thermal insulation layer. A facing layer is separated from the connecting plate by the frame and thermal insulation layer. A plurality of connectors are fixed to the frame. Each connector has a salient area spaced apart from the frame and embedded in the connecting plate. The connecting plate partially overlaps the vertical battens in the thickness direction, the connecting plate forming wood-concrete studs that partially fill the plurality of holes.

Partition system for assembling a partition (3) such as a wall, that is composed of wooden beams (4) with two side faces (8,9) opposite one another extending in the longitudinal direction that determine the width of the beam (4) and with which the beams (4) can be assembled adjacent to one another, wherein connecting pieces (5) are provided to be fitted between adjacent beams (4) in order to keep the beams (4) from one another with a certain clearance (S) in the assembled state and that the connecting pieces (5) are kept at a fixed or practically fixed distance from one another by spacers (6).

Implementations of the present invention relate to systems, methods, and apparatus for providing components of a wall module and a modular wall with the ability to shift or move relative to each other. The ability to shift can reduce or prevent damage to the wall modules during movement of support structures (ceilings, floors, permanent or structural walls) that secure the wall modules, which can shift or move relative to each other during seismic events or otherwise.
