Description

1 / 35 JOINT IN PRESTRESSED FLOOR TECHNICAL FIELD OF THE INVENTION

[0001] The technical field of the invention relates to a joint in prestressed flooring. BACKGROUND OF THE INVENTION

[0002] A prestressed floor, also known as a prestressed slab or prestressed concrete, is a structural construction technique used in building floors and other horizontal elements, such as bridges and parking structures. It involves the use of high-strength steel cables or tendons, which are tensioned after the concrete has been poured and cured. This process provides several advantages, including increased load-bearing capacity, reduced cracking, and improved structural performance.

[0003] The construction process begins with the creation of formwork, which is a temporary mold that defines the shape and dimensions of the concrete slab. Reinforcing steel, usually in the form of a mesh or rebar, is placed inside the formwork to provide additional strength and help distribute loads evenly. Once the formwork and reinforcement are in place, concrete is poured into the mold. The concrete mix is ​​carefully designed to meet structural requirements and achieve the desired strength. Before the concrete hardens, plastic or metal ducts are inserted into the slab. These ducts serve as channels for the prestressed tendons. The ducts are positioned according to the engineering design, which considers factors such as load distribution and structural integrity. High-strength steel cables or tendons are inserted through the Petition 870260054515, dated 05 / 06 / 2026, page 13 / 64 2 / 35 ducts. These tendons are typically composed of several strands of high-strength steel wire wound together. They are designed to withstand significant tensile forces. At each end of the tendon, there are specialized anchors. These anchors are securely fastened to the concrete structure. The tendons are stretched and anchored at one end, while the other end remains free. Once the concrete has cured sufficiently (usually after a few days or weeks), the tendons are tensioned using hydraulic jacks or other tensioning equipment. This process involves applying a significant amount of force to the tendons, which compress the concrete slab. After the tendons have been tensioned to the desired level, they are locked to maintain tension. Sometimes, grout, a special high-strength cementitious material, is injected into the ducts to encapsulate the tendons and protect them from corrosion.

[0004] Joining two adjacent prestressed concrete floors is challenging due to the need to maintain the structural integrity and continuity of the prestressed system while accommodating differential movements between the two adjacent structures. This is particularly important in multi-story buildings or structures where different parts of the building must settle, expand, or contract differently. Expansion joints are commonly used to accommodate differential movements between adjacent concrete structures. These joints can be either mechanical, such as expansion joint assemblies, or structural, such as a gap filled with compressible material. The design of the expansion joint must consider the paths of the prestressed tendons and ensure that they are not compromised by the joint. Petition 870260054515, dated 05 / 06 / 2026, page 14 / 64 3 / 35 Load transfer mechanisms need to be designed to distribute loads from one floor to another efficiently. Proper load transfer ensures that prestressed slabs work together as a unified structure.

[0005] Currently, there are no reliable joints for prestressed floors that bridge the gap between two adjacent prestressed floors, accommodate differential movements between the two adjacent prestressed floors, and are strong enough to effectively transfer a substantial amount of load from one floor to another, for example, when a forklift passes over the joint. SUMMARY OF THE INVENTION

[0006] The objective of the embodiments of the present invention is to provide a reliable and easily installable prestressed floor joint that covers the gap between two adjacent prestressed floors.

This feature is advantageous in ensuring that the second floor profile 400 can be precisely positioned in relation to the dividing member 200 and the first floor profile 300. In addition, the mobility of the second floor profile 400 accommodates the natural expansion and contraction of the poured concrete.This dynamic feature ensures that the concrete can withstand thermal variations and other environmental factors without imposing undue stress on joint 1000. By allowing controlled movement in response to these changes, the 1000 assembly maintains its structural integrity over time, contributing to the longevity and stability of prestressed floors. Furthermore, the second floor profile 400 is equipped with a second flange 410. This acts as a boundary or edge that confines and defines the perimeter of the second prestressed floor, designated as F2 in Figure 1, specifically on the second side of joint 1000. This ensures that the concrete material for the second floor F2 is contained within the designated area.
