Description

FIELD OF THE INVENTION

The present invention relates to the field of climbing scaffolding, specifically designed to facilitate formwork tasks, cleaning of modular panels, movement, and/or transportation of the same.

BACKGROUND

According to the latest technology, there are some related solutions, including disclosures such as international publication WO2009/127007, which shows a climbing mast assembly comprising a mast with multiple recesses along its length. Additionally, it includes a pair of ratchet housings that can slide longitudinally along the mast. These housings are equipped with mechanisms to mount one or more jacks, which are used to couple the housings and adjust their separation along the mast.

In each of the ratchet housings, there are first ratchet elements that enable an alternative sliding movement, transversal to the mast. These elements are selectively positionable to engage with recesses of the mast, limiting the return travel of the housing as it moves upward on the mast through the operation of the jack(s). Second ratchet elements have been integrated into the housings. These elements also have an alternative sliding movement, transversal to the mast, and can be selectively positioned to engage with the recesses. Their main function is to allow the mast to be raised by the jack(s) and, at the same time, limit the return travel of the mast when it is in the process of being raised in relation to the respective housings.

The patent U.S. Pat. No. 4,060,358 discloses a set of climbing scaffolds designed for the construction of in situ reinforced concrete walls, in overlapping layers with variable inclination, comprising a unit with an inverted U-shaped configuration. This unit consists of a support frame arranged laterally to the wall under construction, leaning against a single side of the wall. At the end of the support frame, there is a cantilever member that defines an upper space over the previously cast portion of the wall. Hanging from this cantilever member is a movable frame, parallel and spaced from the support frame, with operating means to adjust its position in relation to the support frame. The setup includes a first formwork panel and a first set of working platforms on the support frame, as well as a second formwork panel and a second set of platforms on the movable frame. These formwork panels correspond to the opposite sides of the wall portion to be molded.

First lockable means are incorporated on the underside of a previously molded wall portion and the second means are incorporated on the support frame. The second means cooperate with the first means and are associated with motor means mounted on the support frame. The second means cooperate with the first means and are associated with motor means mounted on the support frame, which allow the synchronous raising of the entire scaffolding unit, including the support frame, the mobile frame, the cantilever, the formwork panels and the platform sets, from the level corresponding to the last poured concrete layer to the level of the next layer to be poured.

Patent application publication US 2023/0134687 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. The system includes a series of connecting beams, where at least one of them can be connected to and released from the horizontal formwork element. This release capability allows the formwork system to be divided in a longitudinal direction and detached or sectioned from the concrete structure into two or more discrete parts.

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 releasably connected to at least one connecting beam. Jacks connected to a bridge pier which, when actuated, cause the vertical displacement of the main beams. This actuation may be associated with a gear assembly coupled to one of the jacks. Additionally, the system may feature a working platform, and at least one connecting beam can be releasably attached to this platform. A connecting element is introduced between the horizontal formwork element and at least one connecting beam, designed for releasable coupling.

Patent application publication US2015/0184402 discloses a scaffold system comprising first and second wall supports, each composed of a bar and at least one spring that directs the bar in a specific direction. Furthermore, there is a sliding post that includes a sliding hook, a sliding arm, and a hanging pad that is attached to the sliding arm. This sliding post can move vertically within at least one of the first and second wall supports. The system also features a main post that incorporates at least one post hook. This main post is designed to snugly fit complementarily within the sliding post. Additionally, there is a first cover that is securely attached to the main post. A ball screw jack consisting of a mounting plate and a lifting screw is used to allow controlled vertical movement. The mounting plate is secured to the first platform, while the lifting screw is secured to the hanging platform.

In terms of functionality, the sliding hook is adapted to securely engage and disengage with either the first wall mounting bar or the second wall mounting bar. Similarly, at least one post hook is designed to securely engage and disengage with either the first wall mounting bar or the second wall mounting bar.

Considering the above mentioned technology, there is a need to provide a device that allows the efficient transportation of a set supporting modular formwork panels, safe for outdoor work, implementing walkways and/or working platforms and safety features such as railings or others, with a sufficiently rigid structure that allows easy relocation along the construction site, modular in design, having a modular design, easy to clean the modular formwork panels, reducing or eliminating the need for cranes and/or hoists, also having a telescopic or extended structure fixed to the main anchoring structure, optimizing the grip and rigidity of the assembly, having a preferably fast and secure attachment mechanism, thereby favorably reducing assembly and disassembly times, and having a simplified anchoring method.

FIG. 1 reveals a first embodiment that includes a climbing scaffold (1) with a translation motion assisting mechanism (10), which is connected to a formwork unit (20), both of which are supported by an anchoring unit (30).

In a preferred embodiment, the assisting mechanism (10) comprises at least one translation carriage (102) connected to a tensioning device (101) and to a aligning frame (201) belonging to the formwork unit (20) and arranged in a triangular shape between their pivoting or connecting points; in addition, the translation carriage (102) is connected to a translation tensioning device (103); the translation carriage (102) moves and is supported on guides (104) fixed to a horizontal beam (307) of a main bracket body (300); the translation carriage (102) has extensions on which rolling elements are mounted which roll and guide on the lower guide (104a) and/or the upper guide (104b), as appropriate.

The preferred shape of the triangle is preferably a right triangle, where substantially the right angle of 90° is defined between the direction of movement of the translation carriage (102) and the aligning frame (201) or the contact surface against the wall (M) of the modular panels (203). In another configuration, the wall (M) and its associated components for forming it may include an inclination angle different from the right angle of 90°, where the range is between 60° to 120°, and preferably is 90°.

In this embodiment, the assisting mechanism (10), which includes the translation tensioning device (103), is in an active, loaded, or extended position, holding the assembly of components consisting of the translation carriage (102), the tensioning device (101), and the formwork unit (20) in a substantially vertical supporting position to form the poured wall (M), preferably made of concrete; the formwork unit (20) shown in FIG. 1 is only used to form the exterior part of the wall (M), while suitable formwork supports are arranged on the interior side of the wall (M), which are not shown. In this way, the wall (M) is formed by the total assembly of formwork supports.
