Description

“SUSPENDED SCAFFOLDING WITH TELESCOPIC STRUCTURE” Field of Technique

[0001] The present invention relates to the field of climbing scaffolds, specifically those that facilitate the tasks of formwork, cleaning of modular panels, movement and / or transfer thereof. Background

[0002] The prior art contains some related solutions that include disclosures, such as international publication WO2009 / 127007, which describes a climbing mast assembly comprising a mast with several recesses along its length. It also includes a pair of ratchet housings that can slide longitudinally along the mast. These housings are equipped with mechanisms for mounting one or more jacks, which are used to couple the housings and adjust their spacing along the mast.

[0003] Each ratchet housing contains first ratchet elements that allow for reciprocating sliding movement across the mast. These elements are selectively positionable to engage with the mast recesses, limiting the housing's return travel as it advances up the mast through the operation of the jack(s).

[0004] Additionally, second ratchet elements were integrated into the ratchets. These elements also have an alternating sliding motion, transverse to the mast, and can be selectively positioned to engage the recesses. Their main function is to allow the mast to be hoisted by the jack(s) while also limiting the mast's return travel when being hoisted relative to the respective housings.

[0005] US patent 4060358 discloses a climbing scaffold assembly designed for the construction of reinforced concrete walls in situ, in overlapping layers with variable inclination, comprising a unit with an inverted U-shaped configuration. This unit consists of a support structure arranged laterally to the wall under construction, supported on a single side of the wall. At the end of the support structure there is a cantilever element that defines an upper space above the previously cast wall portion.

[0006] Suspended from this cantilevered element is a movable structure, parallel and spaced from the supporting structure, with operating means to adjust its position relative to the supporting structure. The configuration includes a first formwork panel and a first set of working walkways on the supporting structure, as well as a second formwork panel and a second set of walkways on the movable structure. These formwork panels coincide with opposite sides of the wall portion to be cast.

[0007] Furthermore, the first fixable means are incorporated into the underside of a previously cast wall portion, and the second means are incorporated into the supporting structure. These second means cooperate with the first means and are associated with the motor means mounted on the supporting structure. The latter allow the entire scaffolding unit, including the supporting structure, the mobile structure, the cantilever element, the formwork panels, and the walkway assemblies, to be synchronously raised from the level corresponding to the last poured concrete layer to the height of the next layer.

[0008] Patent application US2023 / 0134687 discloses a formwork system used in the construction of concrete structures. The system includes at least one horizontal formwork element designed to support the concrete structure. Additionally, there is a series of connecting beams, at least one of which can be connected to and released from the horizontal formwork element. This release capability allows the formwork system to split in a longitudinal direction and detach or separate from the concrete structure into two or more discrete parts.

[0009] In a specific example, the system also includes main beams that support the horizontal formwork element; and at least one of these main beams can be freely connected to at least one tie beam. Jacks are connected to a bridge pier and, when activated, cause the main beams to move vertically. This actuation may be linked to a gearbox assembly coupled to one of the jacks.

[0010] Additionally, the system may include a working platform; and at least one connecting beam can be freely attached to this platform. A connecting element is inserted between the horizontal formwork element and at least one connecting beam, designed for a release coupling.

[0011] Patent application publication US2015 / 0184402 discloses a scaffolding system comprising first and second wall supports, each comprising a bar and at least one spring that directs the bar in a specific direction.

[0012] Additionally, there's a sliding post that includes a sliding hook, a sliding arm, and a hanging pad that attaches to the sliding arm. This sliding post can move vertically within at least one of the first and second wall brackets.

[0013] The system also features a main post with at least one post hook. This main post is designed to fit snugly inside the sliding post. There is also a first cap that is securely attached to the main post.

[0014] To allow controlled vertical movement, a hand-operated screw jack is used, which consists of a mounting plate and a lifting screw. The mounting plate is attached to the first platform, while the lifting screw is attached to the suspended platform.

[0015] In terms of functionality, the sliding hook is adapted to be securely coupled and released with the first wall mounting bar or the second wall mounting bar. Similarly, at least one pole hook is designed to be securely coupled and released with the first wall mounting bar or the second wall mounting bar.

[0016] When considering the aforementioned state of the art, there is a need to provide a device that allows the assembly that supports the modular formwork panels to be moved efficiently, which allows for safe outdoor work, implementing passage and / or work walkways, and means of safety, such as grids or others, that the structure is sufficiently rigid and allows it to be easily relocated throughout the construction, that it is of the modular type, that the modular formwork panels are easy to clean and that it frees up or reduces the time of use of cranes and / or pulley blocks, in addition to including a telescopic or extended structure that is fixed to the main anchoring structure, optimizing the form of support and firmness of the set, in addition to the support form being preferably quick to fix and safe; thus, reducing assembly and disassembly times favorably, in addition to including a simplified form of anchoring. Subject Matter of the Invention

[0017] The present invention discloses a suspended scaffold with one or more working levels, which includes an anchoring unit with main corbels supporting at least one assistance mechanism that is connected to a formwork unit; the anchoring unit is anchored to a wall, and a second level may also be attached, which includes a telescopic structure supporting a fall arrest mesh. The suspended scaffold includes platforms for passage or work with their safety devices, such as guardrails or railings; in addition, the suspended scaffold is structured primarily with crossbeams.
