Description
- 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.
- In a general mode, the different types of scaffold decks in the market, present, to support the horizontal scaffold bars, in its normal use, claws, hooks or simply curved latches that, which in general, are produced with iron round pipes or with iron rectangular and flattened pipes that are, almost always, curved in one extremity, being the other welded on top of the deck or else fixed directly laterally in the deck.
- With the normal utilization of the decks in the scaffold floors, the weight of its users is totally supported by the support hooks which in case is too frail bends, or if not but welded or riveted directly in the deck, transmits the strength through the deck's zone where welds and rivets are. The constant variations of the load negative/positive, ends by deteriorate the molecules of the materials. It is very usual to find decks with hooks already twisted which when used, are repositioned or straightened with the use of a hammer or a vulgar pipe used as a handspike.
- Generally, when transporting those decks from the place of work to the warehouse and vice versa, when the decks hit there hooks in the metallic structures or walls where they are stored or when the decks fall involuntarily, the hooks that are currently used, break or twist easily in the welded or riveted zone.
- It is known that the deterioration of the decks' hooks with the type of support decks currently used, are a technical problem not only because of the immobilization of the decks for repairing and the financial costs inherent, but also the fragility of the welded zones can induce to ruptures causing accidents and life threatening situations for its users.
- Also, the type of 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.
- In the other hand, if necessary to increase the scaffold structure quantities and that implicate a change of the used scaffold system, which is, to change from tabular to linear or vice versa, the users are faced with the impossibility to use both decks in both systems, because it is not possible to adjust the decks to the horizontal elements in the new structure.
- Equally, when a user intends to acquire new decks to use jointly with the ones that he already has, the user is conditioned to the acquisition of the decks used in the same similar hooks system to the decks already obtained because the other decks in the market are incompatibles.
- 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 offig. 2 ) and the headboard where the support hooks are fixed (nº 3 offig. 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. - The technical studies and the long test made, permitted that this feature was endowed with evolved technical particularities, with optimized configurations and simplified functioning, that permits the adaptability of those decks in any scaffold system, both in the scaffold system with linear support crosspieces or tubular support crosspieces. It is also possible with this feature the easiness to differentiate hooks applications and to be adequate to different distances between the support crosspieces of the different scaffold systems or hooks forms adequate to peripheral configuration of the support crosspiece of those different scaffold systems.
- 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 (nº 1 of
figure 1 ) 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. After applying in the headboard, as shown in figure (23 and 25 offig. 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. º 3) with two holes (7) to introduce the two terminals (12) of the hooks (17, 18 and 19), and the two holes can be positioned higher that the inlaid, as shown (22 and 23), or medium zone of the inlaid as in (3.1 and 3.2 of the same figure). - 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). In the inside of the headboard (3), there is 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 offig. 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 offig. 2 ) that adjusts in the interior inlaid of the headboard face (nº 14 offig. 5 ), permitting that after to press the fixation screw (nº 8 offig. 4 ), the security latch is positioned (nº 11 offig. 5 ) by adjusting the rabbet (14 of fig. nº 5), without oscillation, positioning correctly the two terminals (12) of the support hook. This way, 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.
- Finally, it is a method extremely efficient and economic, because, since it can be used, in parallel with any type of common deck, it does not condition the customers that use this type of components to the use of one unique type of scaffold decks.
