The invention provides a method of constructing a modular multi-storey building including: assembling first and second building modules in a vertical arrangement at an 5 installation location to form a multi-storey building structure, wherein temporary support members between the first and second building modules vertically support at least part of the second building module above the first building module; installing a permanent support structure 10 and connecting it to the first and second building modules to vertically support the second building module above the first building module; and removing the temporary support members.

The invention relates to a method for the cambering of a wooden element, comprising the steps of: cutting to form at least one incision in a surface of the wooden element; inserting an expansive material into the at least one incision of the wooden element; letting the expansive material expand in the at least one incision so that a cambering of the wooden element is achieved.

A steel-structure building envelope includes a building body, floor slabs, and external walls. The building body has H beams and decks. The decks are assembled onto the H beams. The floor slabs have RC slabs laid on the decks. The external walls each have an RC curb formed on the RC slab by means of casting, two steel C profiles, one of which is installed on the RC curb with an opening thereof facing upward, and the other of which is mounted on the deck with an opening thereof facing downward; and an outer wall panel and an inner wall panel, attached to opposite sides of the RC curb and the two steel C profiles, respectively, so that a hollow space is formed between the outer wall panel and the inner wall panel. Thereby the external walls have a two-layer structure and are affixed directly to the floor slabs.

The invention provides a method of forming a concrete floor of a multistorey building, the method including: installing a first building module having a first precast concrete floor slab adjacently spaced from a second building module having a second precast concrete floor slab, at least the first precast concrete floor slab supporting an upstanding support member for supporting an upper floor; forming a channel between the spaced first and second precast concrete floor slabs by providing supporting formwork between the floor slabs for supporting poured concrete; and pouring concrete into the channel to form a concrete connection between the first and second precast slabs, thereby forming a concrete floor of a building.

A connector for connecting a wood substrate to a concrete layer. The connector comprising a shank adapted to engagement with a bore in the wood substrate with a length of the shank aligned with a central axis of the bore, the shank having at least an external portion made of a cement-based composition. In the built-up system, the connectors can have transversal ductile collapse characteristics providing a structural ductility of at least 50% to the built-up system with the wood substrate and concrete layer maintaining an elastic behavior upon the transversal ductile collapse of the plurality of connectors.

The present invention relates to a composite floor, typically a wood/concrete composite floor. The composite floor comprises a support structure being adapted to be attached to a concrete layer. The support structure comprises a top portion being made of at least one support panel comprising at least one opening through which the concrete layer may flow into the inner portion of the support structure once the top portion of the support structure is being disposed on the top of the concrete layer. The upward flow of the concrete creates at least one anchor point, which, once being harden in the inner portion of the support structure, improves the adhesion between the support panels and the concrete and ensures better mechanical rigidity and resistance of the assembly made of the panels and the concrete.

A method of manufacturing a pre-stressed beam or panel and the resulting beam or panel are described. The method includes providing a timber-based component (1); providing a pre-stressing member (9) arranged along the timber-based component; applying a tensile force to the pre-stressing member (9); providing concrete anchors (11a, 11b) at locations that are spaced apart along the timber-based component (1); coupling the pre-stressing member (9) to the concrete anchors (11a, 11b); and releasing the tensile force on the pre-stressing member (9) to transfer a compressive force to the timber-based component (1) through the concrete anchors (11a, 11b) to form a pre-stressed beam or panel.
