[0001] SCAFFOLD ASSEMBLY WITH LIFTING SYSTEM

[0002] FIELD OF THE INVENTION

[0003] The invention relates to a load-bearing scaffold assembly that is positioned between a lower ground and an upper ground, which is located above the mentioned lower ground and on which concrete will be poured, allowing formwork placement on the upper ground and enabling concrete pouring

[0004] BACKGROUND OF THE INVENTION

[0005] Formwork scaffolds are temporary structural systems used in the construction industry to create building floors and provide a working platform for construction workers. These scaffolds are a critical component of construction projects and are of great importance in terms of both safety and functionality. During the construction process, tasks such as concrete pouring, formwork assembly, and reinforcement placement are carried out while constructing reinforced concrete building floors. Proper installation and use of formwork scaffolds are essential for worker safety and construction efficiency. Incorrectly installed or inadequately secured scaffolds can lead to workplace accidents and disruptions in the construction process. Additionally, the materials used for scaffolding must be of high quality and durable.

[0006] The concrete pouring process in high-ceiling buildings is a complex operation that involves technical and logistical challenges. Initially, an additive scaffold is used to transport the concrete to the desired height. As the height of the scaffold increases, ensuring its stability becomes more complicated. To guarantee safety, scaffolds must be properly secured and regularly inspected. During scaffold installation, ground conditions and the suitability of the surrounding area must be carefully evaluated. Additionally, transporting materials and equipment onto the scaffold poses extra risks for workers and causes time loss. When scaffolds need to be frequently relocated or reconfigured, this process can be both timeconsuming and labor-intensive.

[0007] As a result, all the abovementioned problems have made it necessary to make an improvement in the relevant technical field. SUMMARY OF THE INVENTION

[0008] The present invention relates to a load-bearing scaffold assembly designed to eliminate the aforementioned disadvantages and introduce new advantages to the relevant technical field.

[0009] One objective of the invention is to provide a scaffold assembly that reduces labor force requirements and saves time and cost.

[0010] To achieve all the objectives mentioned above and that will emerge from the following detailed description, the present invention relates to a load-bearing scaffold assembly that is positioned between a lower ground and an upper ground, which is located above the mentioned lower ground and on which concrete will be poured, allowing formwork placement on the upper ground and enabling concrete pouring. An improvement of the present invention is that it comprises at least one lower module positioned on the lower ground, at least one upper module allowing the placement of formworks, and a lifting system positioned between the mentioned lower module and the mentioned upper module, enabling the upper module to be elevated with respect to the lower module. Thus, in this way, the working scaffold is assembled while reducing labor force requirements and saving time.

[0011] A possible embodiment of the invention is characterized in that it comprises at least one cylinder providing actuation to operate the lifting system and enabling the upper module to move upward from the lower ground with the aid of hydraulic pressure. Thus, the movement of the lifting system is provided.

[0012] A possible embodiment of the invention is characterized in that the lifting system comprises multiple arms that are interconnected at their ends and centers, forming a scissor structure. Thus, space savings and equal distribution are provided, and a safe movement is achieved.

[0013] A possible embodiment of the invention is characterized in that it comprises at least one scaffold head extending towards the upper ground to be positioned under connected beams or other structural elements on the upper module. Thus, it allows the formwork where concrete is poured to be connected to the scaffold assembly. A possible embodiment of the invention is characterized in that the lifting system comprises at least one sliding rod positioned on both the lower module and the upper module, positioned parallel to the short edges connected to the long edges of the lower frame and the upper frame, enabling the movement of the scissor structure towards the upper ground with the power transmitted from the cylinder, and providing movement along the long sides of the lower frame and the upper frame. Thus, the movement of the scaffold assembly upward or downward with respect to the ground is provided.

[0018] DETAILED DESCRIPTION OF THE INVENTION

[0019] In this detailed description, the subject of the invention is described utilizing examples only for clarifying the subject matter such that no limiting effect is created.

[0020] A representative isometric view of the scaffold assembly in its closed state is shown in Figure 1. Accordingly, the formwork scaffold is a temporary structural system used in construction projects to support and secure formworks during concrete pouring. It comprises at least one scaffold assembly (10), which can be in an automatic or semiautomatic structure and can be installed beneath the surface where concrete is poured in construction sites. Construction sites include at least one lower ground (30) and at least one upper ground, which is located above the mentioned lower ground (30) and on which concrete will be poured. The mentioned scaffold assembly (10) comprises at least one lower module (31) positioned on the lower ground (30). The lower module (31 ) assumes the role of carrying the scaffold assembly (10).

[0021] The lower module (31 ) comprises at least one lower frame (32). The lower frame (32) is rectangular in its preferred configuration. The lower frame (32) includes at least one leg (34). In a possible embodiment of the invention, the mentioned leg (34) is fixed to all four ends of the lower frame (32). The lower frame (32) comprises four legs (34) and is secured parallel to the lower ground (30). The lower module (31 ) is made of high-strength and corrosion-resistant materials capable of supporting the scaffold assembly (10). The scaffold assembly (10) comprises at least one upper module (20) positioned parallel to the lower module (31 ) and allowing the placement of formworks.

[0022] The mentioned upper module (20) allows the molds to be placed on it. . The upper module (20) comprises at least one upper frame (21). In its preferred configuration, the upper frame (21) is rectangular. The upper frame (21 ) and the lower frame (32) are of the same dimensions in the preferred configuration. The upper module (20) is positioned parallel to both the lower module (31) and the upper ground. The upper frame (21) comprises at least one scaffold head (23) attached to all four ends. The scaffold head (23) is U-shaped in its preferred configuration. The mentioned scaffold head (23) extends towards the upper ground to be positioned under connected beams or other structural elements on the upper module (20). Thanks to its adjustable features, it can be used at different heights and allows workers to perform applications easily during the construction process. There are four scaffold heads (23) in the preferred configuration. The scaffold head (23) has a galvanized structure.

[0023] Two scaffold heads (23) located at the two ends of one short side of the upper frame (21) are fixed, while the two scaffold heads (23) at the ends of the other short side can be adjusted to the desired length by being connected to pipes (22) that are evenly spaced along the long side. The upper frame (21) comprises at least one pipe (22) positioned along its long sides. The inside of the pipes (22) is hollow and provides connection to the scaffold head (23). The pipes are positioned opposite each other in an equal manner on the long edges of the upper frame (21) and, in the preferred configuration, there are four of them. This allows the scaffold head (23) to be fixed to the desired pipes (22) and meet the operational requirements of the scaffold head (23).

[0024] A representative isometric view of the scaffold assembly in its open state is shown in Figure 2. Accordingly, the scaffold assembly (10) comprises a lifting system (11) positioned between the upper module (20) and the lower module (31 ), enabling the upper module (20) to be elevated relative to the lower module (31). The lifting system (11 ) is connected to the lower frame (32) on the lower module (31 ) and the upper frame (21 ) on the upper module (20). The lifting system (11) provides for the upper module (20) to reach the desired height. As the upper module (20) moves towards the upper ground, it rises perpendicularly relative to the lower module (31). The lifting system (11) essentially consists of a scissor mechanism. To form this scissor structure, the lifting system (11) includes at least one arm (13). As the upper module (20) approaches the upper ground, the arms (13) take an X form. The lifting system (11) is designed so that the number of arms (13) can be increased when the height increases. The arms (13) are interconnected at their ends and centers and are linked in a rotatable zigzag form. The lifting system (11) comprises at least one sliding rod (33) in its connection with the lower frame (32) and the upper frame (21 ). The sliding rod (33) provides movement parallel to the long edge on the long edge of the lower frame

[0025] (32) as the arms (13) open towards the upper ground. In this way, while the scissors are opening, the upper module (20) is raised to the upper ground, thanks to the sliding bar

[0026] (33). The sliding bar (33) provides movement on the long side of the upper frame (21) parallel to the long side, as the arms (13) open towards the upper floor. In its preferred configuration, the sliding bar (33) is in two pieces, one in the upper module (20) and one in the lower module (31 ).

[0027] A representative front view of the scaffold assembly is shown in Figure 3. Accordingly, opposite the sliding rod (33), there is a fixed rod connected to the short sides of the lower frame (32) in a rotatable manner and positioned parallel to the sliding rod (33). The ends of these fixed rods can rotate according to the movement of the scissor mechanism. When the scissor mechanism is in the closed position, it is partially parallel to the lower ground (30). As the scissor mechanism opens, the interconnected rods take an X shape, increasing their angle relative to the lower module (31). As the scissor mechanism closes, the angle of the interconnected arms (13) decreases, bringing them closer to the lower module (31). The scaffold assembly (10) comprises at least one cylinder (12) that activates the scissor mechanism to enable the movement of the lifting system (11).

[0028] The cylinder (12) is positioned between two parallel arms (13) located between the upper module (20) and the lower module (31). The cylinder (12) functions as the actuating element that activates the lifting system (11). In its preferred configuration, the cylinder (12) receives its motion from a manually operated single-acting hand pump or an electrically driven hydraulic power unit. Additionally, the cylinder (12) can also be powered by manually operated rack-and-pinion or trapezoidal screw systems. The incoming power opens the cylinder (12), and the movement of the lifting system (11) is provided. Thus, the upper module (20) is raised to the desired height, and the working scaffold can be assembled. Accordingly, instead of an additive scaffold structure in high-rise constructions, the invention provides a scaffold assembly (10) that includes a lifting system (11) operating on the "manlift" principle, allowing easy installation, reducing labor force requirements, and saving time. The protection scope of the invention is specified in the appended claims and cannot be limited to the description made for illustrative purposes in this detailed description. Likewise, it is clear that a person skilled in the art can present similar embodiments in the light of the above descriptions without departing from the main theme of the invention.
