Definitions
- the present invention describes a new type of support hook and headboard where they insert, being the proper set to apply in the decks that are used in construction scaffold structures or in decks used as a stage floor or in similar technical metallic structures support that are used in several events.
- hooks or decks supports currently used can induce to accidents to its users, as much as for scratches or deep blows, as well as rips in the working clothes, that, generally are made by the hook tip used to support decks.
- This invention includes a new type of hooks to support the scaffold decks (no 1 of figure 1 ) by components used to position and fix the hooks at the headboard (no 2 of fig. 2 ) and the headboard where the support hooks are fixed (no 3 of fig. 3 ) solve globally the problems related previously, permitting the production of new decks, more resistance and more safe, in such way versatile, that it can be used in any well-known scaffold system. This represents the main advantages of this feature.
- This invention presents three types of different support hooks (17, 18 and 19 of figure 1 ), having these geometrical configurations that better adjust to the crosspieces of the scaffold system elements currently known, but the support hooks can always be produced with front geometrical configuration adaptable to any type of support crosspiece, without loosing the technical quality and capacity that are evident with the presented formats because the fixation method proposed at the headboard, is not modified.
- the support hooks in this invention are produced in massive steel pipe that can have a round, rectangular or octagonal sections or any other geometrical peripheral normalized form. As shown in the attached drawings, they are curved from a complete material section, do not present any welds or edges and are treated superficially after produced.
- the headboard As shown in figure (23 and 25 of fig. 3 ), ( fig. 4 ) and ( fig. 5 ) in the frontal part enhanced in the headboard, it is serve to support the crosspieces. It always ends with a curve (13), and the two terminals or hook tips (12) stay always protected in the headboard interior and do not cause damages.
- the headboard (no 3 of fig. 1 ) is all in steel with special superficial treatment with variable thickness, implying in its production the previous piece planning, due to its stamping, cut and its adequate technical perforations, being after sequentially bended.
- This deck headboard does not have any type of welds and presents a geometrical configuration that permits its coupling in any type of known decks and after applied in the deck, presents all its edges and exterior round corners.
- the headboard (no22 to 25 of fig. 1 ) can present fronts with little technical variations in order to adequate to the scaffold system or the type of hooks that can be applied. That is why the headboard can have or not a pipe of variable dimensions (16) in one of the sides, which main purpose is to equalize the deck support, when the support hooks do not permit an efficient nesting of the deck.
- This headboard can present two or more places to apply the same number of hooks, according with the decks' width. These places present an adequate inlaid inside to the outside (6 fig. n.
- the hooks are applied and positioned in the frontal headboard zone, being its two tips of the terminals (12) threaded by holes (7) of the inlaid (6).
- a security latch no 2 of fig. 2
- using security latches for each hooks in the headboard with two grooves lowered in half cane (n. 5 of fig. 2 ) to rabbet the two terminals (12) of the hook (1) and two or more faces in square angles, one of them presenting an enhance (no 2 of fig. 2 ) that adjusts in the interior inlaid of the headboard face (no 14 of fig. 5 ), permitting that after to press the fixation screw (no 8 of fig.
- the security latch is positioned (no 11 of fig. 5 ) by adjusting the rabbet (14 of fig. no 5), without oscillation, positioning correctly the two terminals (12) of the support hook.
- the parquet blocks (2), the squeezing screw (8), with the use of two bolts and nuts, guaranties the solid adjustment of the hooks in the headboard structure does not permit any involuntarily recess or landslide between the headboard and the hook.
- This type of support hooks with pieces that permit its fixation to the headboard structure presents the security positioning and squeezing latches (2) and the screw (8) that after inserted in its place does not wheel and permits an easy and correct squeezing of the nut (9) applied by the headboard interior and the easy application of these components to the scaffold decks, are surely one added technical value for scaffold users safety, clearly much superior to the hooks currently used in the market.
- This new type of hook has also the particularity to be removable, this is a characteristic that in case of deterioration, motivated per example, by the decks' fall or by its bad utilization, permits to the hooks to be substituted by others similar, having has immediate consequence a huge reduction of financial costs, when compared with the immobilization costs and welding used until now, and having still more value for the decks' instalment therefore the quality remains the same, as well as its safety.
