Definitions

  • This invention refers to a complete safety system applicable to construction sites of the type that consist of a number of support pieces with tubular configuration, intended to be fixed permanently to the structure of the construction by incorporating them into the frame and/or by welding them to the metal structure of the frame, leaving one of the openings of these tubular parts accessible.
  • safety nets For example, in the field of construction, widespread use is made of safety nets to prevent workers falling long distances, with these nets and their supports frequently fixed by cords to the columns or structure of the building.
  • the fixing points for safety cables for form setters are fixed to metal posts that are mounted on sleeves or supports built into the concrete or soldered to the metal structure of the structure under construction. In other cases, these cables are fixed to posts that have a perforated plate at the lower end so that they can be screwed on to the frame, or support clamps that grip onto a floor of the frame.
  • Protective canopies to prevent rubble or other materials falling down to the pavement below are usually positioned using a number of horizontal brackets positioned to jut out and fixed using screws and/or welded to the frame or to the facade of the building on which work is being carried out, with the edges of the consecutive plates of the cover then fixed onto the abovementioned brackets. This leads to a high level of instability, with the consequent risk of falling of the plates that have been screwed/welded in a jutting out position and the resultant fall of the materials that have accumulated on them.
  • support pieces in tubular form are used. These are fixed permanently to the structure, allowing the attachment of a specific safety element.
  • safety guard bars are fixed to a support that partially emerges from the inbuilt support piece, to which it is fixed using an internal bolt.
  • inbuilt support pieces can constitute a problem for worker safety, particularly during repair and/or building conservation tasks, as the strength of the mounting of the safety guard bar depends on internal pieces (supports and bolt) the state of preservation of which cannot be checked.
  • the safety guard railing is fixed to the inbuilt support piece using an end tooth which is inserted into a cavity to the back of the support and which is immobilised in this position with a "U"-shaped wedge that is also inserted into the support and fixed using an external screw.
  • the mounting of the safety guard involves significant risk for the worker, as he or she must go beyond the frame in order to insert the edge of the bar into the front of the support piece and then for the positioning of the wedge and the tightening of the screw.
  • the safety guard itself is moved towards the edge of the frame, which obviously means that it provides insufficient safety protection.
  • the safety system that is the subject of this invention is of the type that consists of a number of support pieces that are tubular in configuration, intended to be fixed permanently to the structure of the construction by incorporating them into the frame and/or by welding them to the metal structure of the frame, leaving one of the openings of these tubular parts accessible.
  • This safety system has certain specific construction characteristics intended to allow the stable and reliable fixing of different safety devices onto these support pieces, such as safety guard rails, safety cables, safety nets, protective canopies, suspended scaffolding, harnesses or any other safety element required, using interchangeable supports of different configurations for this.
  • a special feature of this invention is that all of the interchangeable supports have the same measurements to allow them to be coupled to the inbuilt support pieces.
  • This safety system provides a series of advantages, among which the following should be highlighted: appropriate protection for workers during the installation of the system itself and particularly during the installation of the support pieces that are incorporated into the perimeter area of the frame, allowing one or more safety elements to be mounted on these support pieces using a single interchangeable support, according to the requirements of each case, allowing platforms to be fitted to the perimeter of the frame that enable the comfortable and safe operation of workers and the formation of extendible auxiliary railings for those areas that are a significant distance apart on the horizontal and that are not as a rule covered by the main railings.
  • this system consists of a number of interchangeable supports intended to be fixed temporarily to support pieces that are fixed permanently by incorporation, welding, etc. to the structure of the building.
  • These interchangeable supports provide the means for fitting certain safety devices, such as: safety guard with baseboard and railing, head pieces for lifelines or safety cords for form setters, angled brackets for the upper fastening of safety nets, supports for the lower fastening of safety nets, supports for safety canopy coverings, telescopic supports for the support of scaffolding or tubular structures and supports for platforms.
  • the abovementioned interchangeable supports are fitted with a fixing device to allow them to be fitted to and retained on the support pieces.
  • This fixing device consists of: a tubular section partially housed in a tubular configuration of the interchangeable supports and two folding retention feet that partially jut out beyond the tubular section at the end of the support and that have two side claws facing in opposite directions jutting out over the front edge.
  • These feet are fitted at the rear to a common axis associated with the corresponding interchangeable support and which can be turned between an operating position in which the claws jut out to the side over the lengthwise projection of the external tubular section in order to fit onto the corresponding support piece and a non-operative position in which said side claws remain within the space delimited by the lengthwise projection of the external tubular section, allowing them to be freed from the support piece.
  • the interchangeable supports provide a transverse passage for fitting an extractable wedge that, in the position of use, is hosted in the transverse passage and is positioned between the two retention feet, keeping them in the operating position of fixing the corresponding interchangeable support to one of the support pieces.
  • the support pieces internally define two side cavities which are set face to face to house the respective claws of the support piece when in the abovementioned operating position, with the two feet providing double anchoring for the interchangeable support on the support piece.
  • the fitting of the wedge requires the separation of the anchoring feet, which prevents the insertion of the wedge if the feet are not correctly positioned inside the support pieces and prevents the incorrect fixing of the interchangeable supports with respect to the support pieces.
  • the turn axis of the retention feet is mounted on the transverse holes cut out of the interchangeable supports and fixed to this support using nuts that are accessible from the outside, which allows the axis to be dismounted and substituted should it show any sign of deterioration.
  • transverse holes for mounting the axis of the retention feet are slightly lengthened in the lengthwise direction of the support, which means that higher fabrication tolerance can be used without reducing the effectiveness of the anchoring, taking into account the fact that the wedge acts against the front side of the windows mentioned and against the jutting out additions on the internal sides of the retention feet, ensuring on the one hand the separation or opening of the retention feet and on the other the correct mounting of the interchangeable support on the support piece, making all of these parts into a stable and unmovable grouping.
  • the system has several interchangeable supports, which are fitted with the corresponding fixing device for their coupling to the inbuilt support pieces.
  • These interchangeable supports offer the appropriate configurations for allowing diverse safety elements to be fitted to them, either directly or with the help of intermediate supports.
  • the protective elements intended to be fixed directly or with the help of intermediate supports are: angled brackets for the upper fastening of safety nets, safety guards with railings, protective canopy coverings.
  • the intermediate supports allow the attachment of the abovementioned protective elements and other elements, such as suspended loads or tubular structures, to the interchangeable supports.
  • the system consists of a number of positioning bases for fixing the support pieces which are intended to be incorporated into the frame, so that said support pieces remain static during the pouring of cement, which guarantees their correct positioning, and of auxiliary supports for the mounting of safety guard railings on the formwork boards.
  • Two support pieces (1, 1a) can be seen in the figures that are of tubular configuration in a "T" shape. These are intended to be incorporated or fixed definitively to the construction so that the mouth of the central wing remains accessible from the outside in order to allow the coupling of different interchangeable supports (30a, ... 30f).
  • the support pieces (1a) consist of a steel rope or cable (11) intended to remain in a protruding and visible position in order to provide a coupling and permanent fixing point for workers implementing a safety system.
  • These support pieces (1a) also have tubes (12) on the sides to allow them to be fixed to the beams of the frame assembly. These support pieces (1a) will preferably be positioned vertically and corresponding with the pillars of the frame.
  • the support pieces (1 and 1a) allow certain interchangeable supports (30a, ... 30f) shown in figures 8 to 16 to be coupled and fixed to them.
  • Each of said interchangeable supports has a fixing device (4) on one of its ends, to allow it to be immobilised on the support pieces (1, 1a).
  • this fixing device (4) consists of: an external tubular section (41) that can be coupled internally to the support pieces (1, 1a) and two retention feet (43) which at the front end have two side claws (44) facing opposite directions.
  • These retention feet (43) are mounted at the rear end on a common axis (42), which can be turned between: an operating position in which the claws (44) jut out to the side over the lengthwise projection of the external tubular section (41) to in order to fit onto the corresponding support piece (1) and a non-operative position in which said side claws (44) remain within the space delimited by the lengthwise projection of the external tubular section (41), allowing them to be freed from the support piece (1).
  • the feet (43) are immobilised in the open or anchoring position by a wedge (45) that is inserted into a transverse passage (46) to remain in position between the two retention feet (4).
  • this invention consists of a number of positioning bases (2) shown respectively in elevation and section plan in figures 6 and 7.
  • the tops of these positioning bases (2) define the routing (21) for the stable, horizontal support of the support pieces (1) and support feet (22). Both the routing (21) and the feet (22) have holes (23) to allow the mounting of fixing elements such as nails, screws or similar.
  • the interchangeable support (30a), shown in Figure 8, has a straight tubular section (301) which has a number of elements fixed to it: at one end is the corresponding fixing device (4), to the top is a diagonal tubular section (302) for coupling various protective elements and at the front end, a ring (305) for anchoring cables, tensioners or similar elements.
  • the diagonal tubular section (302) is facing the frame, which allows the worker to have easy access to it from the frame, reducing the risk of falling accidents.
