摘要:
A smoke discharging chimney (1) comprising a plate (3), a first tubular element (5) associated to the plate (3), and a second tubular element (9) apt to be coaxially coupled with the first one (5). The first tubular element (5) has a lateral surface (6) having at least one closed portion and, at least one protruding engagement portion ( 14) developing transversally along the respective lateral surface (6, 10) so as to mutually engage the two tubular elements (5, 9). The protruding engagement portion (14) can be interrupted and develops transversally on a lower portion of the lateral surface (6, 10) of the first (5) and/or of the second tubular element (9) with respect to the circumference thereof, so as to help the discharge outside the chimney (1) of condensate that has built up from smoke inside said tubular elements (5, 9).
摘要:
The present invention relates to an anchoring equipment (1), in particular for roofs (6), comprising two identical supporting elements (2, 3) having each an engagement portion (4, 5) that can be adapted to the shape of the roof (6) on which the equipment (1) has to be installed, and a fastening portion (7, 8) apt to be engaged by an end (20a, 20b) of a connecting rope (20) placed between said supporting elements. The equipment further comprises at least one retaining element (23) placed between the supporting elements (2, 3), provided with an engagement portion (24) that is identical to the engagement portion (4, 5) of each supporting element (2, 3). The retaining element (23) has a retaining portion (25) apt to retain possible transversal shifts of the connecting rope and to enable the sliding along the latter of at least one hooking and/or safety fixture used during maintenance operations carried out on the roof (6).
摘要:
A supporting device (1) for safety lines comprising a main body having a substantially plate-like conformation and rigidly fixed to a building structure (60) and an anchoring body having a substantially plate-like conformation and provided with a constrained end integrally fixed to the main body and a free end, wherein the plan area of the main body is greater than the plan area of the anchoring body, wherein the anchoring body has a series of folding lines interposed between the free end and constrained end, each pair of adjacent folding lines delimiting a respective sub-portion of the anchoring body so as to define a series of sub-portions each lying in a plane oblique to the lying plane of the adjacent sub-portions; wherein the anchoring body is structured for deforming at least at said folding lines due to a tensile force applied to said free end so that the free end changes its position relative to the constrained end.
摘要:
A rung (1) for fall-prevention ladders having a plate shape and a longitudinal development axis (2), the rung comprising a central wall (3), a first lateral wall (4) and a first bend (10) substantially parallel to the longitudinal development axis, the bend being interposed between, conjoining and demarcating, the central wall and the first lateral wall, the central wall and the first lateral wall being each provided with a respective external surface (3a, 4a) and a respective internal surface (3b, 4b), the rung comprising at least a through-hole (6), at least said central wall and defining an annular surface (7) of the hole provided with an external edge (8) on the side of the external surface, the external edge of the hole extending up to the first bend.
摘要:
An anchoring device (1) for a life line (100) comprising a first body (3) and a second body (4), where the first body comprises a fastening portion (5) intended to be fixed to a building structure and a connecting element (7) rigidly connected with the fastening portion, wherein the second body comprises an engaging portion (10) intended to be engaged by a cable (50) of the life line and a coupling portion (11) comprising a lateral wall (12) which delimits a housing cavity (13) conformed such as to at least partially receive the connecting element (7), where the second body is fixed in a pivoting manner to the first body and where the lateral wall of the coupling portion has a weakened line (20) structured in such a way that the lateral wall opens along the weakened line at a predetermined threshold value of a force applied on the engaging portion.
摘要:
A supporting device (1) for safety lines (100) comprises a supporting element (2) comprising a plate-shaped main body (3) and a portion (4) for mechanical coupling to a cable (101) of the safety line; - a first and a second wing (5) which are plate shaped, being rigidly fastened to a building structure, where at two opposite ends the main body (3) comprises a plurality of through slits (8) and where each wing has a plurality of protruding tabs (9) inserted in the slits of a respective side wall in order to produce a mechanical coupling between the main body and the respective wing, the wing being able to rotate about an axis of rotation (10) positioned along the main direction of extension of the slits.
