A PPVC connector is provided for joining a first PPVC (Prefabricated Prefinished Volumetric Construction) module and a second PPVC module. The PPVC connector is adopted for coupling or joining a first PPVC module and a second PPVC module together, comprising a first anchor for attaching to the first PPVC module; a second anchor for attaching to the second PPVC module; and a frame for coupling the first anchor and the second anchor together. The first anchor, the second anchor, the frame or a combination of any of these components comprise a plate having at least one side for attaching to one of the PPVC Module. Due to confinement effect, the first module and the second module are prevented from detachment so as to bind the first PPVC module and the second PPVC module together permanently to form a monolithic assemble.

A building module which is a sandwich panel comprising a first region which provides part of the roof structure of a building, a second region which provides part of the wall structure of the building, and a third region which provides part of the floor structure of the building.

The invention relates to a hollow board material comprising a first sheet and a second sheet. A first and a second lath are arranged in parallel between the first sheet and the second sheet along opposite edges of the hollow board material. The first lath and the first sheet are attached to each other by means of a first metal gripping lamina which at least partly covers the first lath. The second lath and the first sheet are attached to each other by means of a second metal gripping lamina which at least partly covers the first lath. Optionally, the first lath and the second sheet are attached to each other by means of a third metal gripping lamina and optionally the second lath and the second sheet are attached to each other by means of a fourth metal gripping lamina. The metal gripping laminas have a first face and a second face which are opposed to each other. Each face comprises a plurality of sharp projections extending substantially perpendicular therefrom and into the laths or the sheets respectively. The metal gripping laminas thereby provides a hollow board material and increases the bending strength of the hollow board material. The invention further relates to a furniture comprising said hollow board material and method for producing said hollow board material.

Disclosed is a method for forming a hollow pipe-sandwiching metal plate and applications thereof. The hollow pipe-sandwiching metal plate comprises a first panel, a second panel, and multiple hollow pipes between the first panel and the second panel; gaps are arranged among the hollow pipes, and the hollow pipes are connected to the first panel and the second panel by brazing. The present disclosure further includes the applications of the hollow pipe-sandwiching metal plate. The hollow pipe-sandwiching metal plate has advantages, such as light weight, high strength, low stress, high temperature resistance, pressure bearing, thermal insulation and vibration isolation. The metal plate will not deform due to thermal difference, thereby providing permanent service life of the metal plate.
