A simplified framing system with two or more arches which are joined together into a unitary structure by means of connector elements. Each arch is joined to a base by means of connector elements herein termed “base frame connectors”. The angle frame connectors and base frame connectors are preferably fabricated from sheet metal by conventional die cutting and press-forming or stamping techniques. The simplified framing system of this disclosure is particularly designed for assembly using nominal 2×4 inch lumber. The system does not require cutting the lumber except for straight, perpendicular cutting of the lumber to the desired lengths.

A modular system for the dry building of structures for constructions, such as walls, floors, balconies, roofs or the like, includes a plurality of planar modular beams that define a respective plane and that are mutually jointed, and a plurality of planar panels anchored thereto at least at or in proximity of the end portions of the same planar modular beams.

A wooden house includes a roof, a wooden frame mechanism, a base, and a fixed wall panel, wherein the wooden frame mechanism with the roof mounted on the top is inserted on the base; the present invention realizes the quick mounting and dismounting of the first main cross beam and the upright post through the matching of the vertically movable wedge block and the first wedge that fixes the wedge tenon to the wedge mortise. At the same time, because the wedge mortise is connected to the common mortise, after dismounting the first main cross beam, the second wedge and third wedge are pushed into the wedge mortise through tools, to achieve the removal of the sub-cross beam from the upright post, thereby improving the efficiency of mounting and dismounting of the entire house.

A building and construction method include improved workability not causing variation in quality of buildings, by easily joining materials without special processing by forming mortises. A wooden building constructed by fitting horizontal and vertical members includes lower frames, first upper frames, second upper frames, and side joists as horizontal members; and pillars as vertical members, wherein the lower, first upper and second upper frames, and side joists include mortises at part of the lower, first upper and second upper frames, and side joists in longitudinal direction, the first upper frames include an entire length recessed groove in longitudinal direction, the second upper frames include an entire length protrusion in longitudinal direction, the mortises at the lower frames and the first upper frames are through holes, and the pillars include protrusions at both ends, fitting into the mortises at the lower, first upper and second upper frames, and side joists.

An engineered wood structural system including multiple vertical structural elements (10) including first seats (11) comprised between parallel vertical struts (12) made of successive aligned vertical strut segments (13) connected to each other, multiple horizontal structural elements (20, 120), supported on the said first seats (11), each including an upper horizontal board (21) and a lower horizontal board (22) with at least one second spacer (23) placed in between, and optionally slab members (30) supported on the said horizontal structural elements (20, 120) defining at least one structure floor (1).

A construction having generalized and alternative joints, capable of making pillar materials self-stood at in horizontal direction of lower frame materials. Upper and lower frame materials formed by laminating three sawn plates with two or more different plate width in plate thickness direction, and a recessed groove or a protruding stripe of the alternative joints is formed between outer layer plate width of outer layer sawn plates interposing an intermediate layer of laminated layers and an intermediate plate width of intermediate sawn plate interposed as the intermediate layer. The pillar materials are formed by laminating three sawn plates with same length in plate thickness direction, and a protrusion or a recess, which can be fitted closely to the recessed groove or the protruding stripe, are formed at both ends by deviating an intermediate sawn plate in a longitudinal direction for a distance of the difference to outer layer sawn plates.

An engineered wood structural system including multiple vertical structural elements (10) and multiple horizontal structural elements (20, 120) wherein multiple horizontal structural elements (20, 120) of the same floor level are laterally adjacent slabs connected to each other through a perimetral region of the upper horizontal board of one slab attached to a perimetral region of the upper horizontal board of other laterally adjacent slab directly, through complementary staggered steps or through a joint connector, to transfer horizontal loads.

A construction system includes a set of constituent elements, at least one of which includes at least two superimposed folds each including at least two wooden structural boards. In this system, at least two constituent elements are fixed together by a non-adhesive fixing device and at least two adjacent folds are held against each other by non-adhesive holding device. The faces in contact with two structural boards are at least partially provided, at their contact interface, with a set of grooved patterns arranged so as to prevent the structural boards from sliding one relative to the other along at least one first immobilisation axis. A method for manufacturing such a construction system is also disclosed.
