Disclosed is a half-face respirator-type mask, which comprises: a mask body with at least two identical circular openings; and at least one inhalation port and at least one exhalation port, positioned in the openings. Each port comprises at least one tubular element having a longitudinal passage for air to pass, with a first end for the inlet of air and a second end for the outlet of air, the second end of the tubular element being received by the first opening, and the first end of the tubular element projecting towards the outside of the mask body. The tubular elements of each port are identical tubular elements, arranged according to the air flow direction determined by inhalation and exhalation, respectively.
The invention relates to a construction system formed by wood panels (600) and plastic connectors, which comprises: female connectors (100), male connectors and wood panels, wherein the female connectors comprise a pair of plates (101) having a rectangular surface (102) with rounded distal corners (103), with a first perforation (104) in the distal area, said first perforation being rectangular with rounded ends (105), and a second perforation (106) at the proximal end, said second perforation being rectangular with rounded distal ends (107) and adjacent to a curved raising border (108) running along its distal perimeter and which extends to form lateral sections (109) adjacent to the proximal end of the rectangular surface, both plates being connected by the top edges (110) of the lateral sections. The wood panels include one or more recesses (602) that fit together with the border of each female connector, one or more female connectors being assembled to one or more male connectors.
