Description

Field of technology

The floor slab will find application in the construction production in the construction of floor structures in residential construction, as well as for office buildings, shops and others, regardless of their number of storeys.

BACKGROUND OF THE INVENTION

It is known from the application floor slab, which includes load-bearing and distribution reinforcement, connected with load-bearing vertical elements, which load-bearing and distribution reinforcement are covered by monolithically poured concrete. This is how a floor slab with an upper and lower surface is formed. Under the lower surface of the slab, usually when it is first in height, a thermal insulation layer is mounted, by means of fixing means. In addition to bearing the loads from the respective floor, the floor slab is also used for thermal insulation of the building or the respective floor. The disadvantages of the known floor slab are that for its construction a significant amount of reinforced concrete poured on site is used, as it itself has a height determined by the load and the opening, and significantly increases the total weight of the building. Formwork is used for pouring the concrete on the slab, the installation of which slows down the construction process. The dismantling of the formwork also contributes to a significant delay, as the required strength of the poured concrete is expected to be reached. In addition, additional fixing means are used for the installation of the thermal insulation layer, which slows down the construction process or, in the case of the use of adhesive compositions, creates an opportunity for deterioration of the quality of the final product or leads to significant cost.

Technical essence of the utility model

The problem with this utility model is to reduce the consumption of concrete while maintaining the load-bearing capacity of the structure, as well as to provide the opportunity to install thermal insulation when necessary, including speeding up the construction process.

The problem is solved with a floor slab, which includes distribution reinforcement connected to load-bearing vertical elements and covered by monolithically poured concrete. According to the utility model, the floor slab also includes reinforced prestressed beams located parallel and at a distance from each other, the reinforcement of which is connected to the bearing vertical elements. In this case, the reinforced prestressed beams have a reverse T-section with a lower horizontal flange and a vertical stem. Between the reinforced prestressed beams are located filling elements mounted to their lower horizontal flange, and the distribution reinforcement, covered by monolithically poured concrete, is located above the reinforced prestressed beams and the filling elements.

It is recommended that the filling elements have an upper surface located lower than the upper end of the reinforced prestressed beams.

According to an embodiment, the vertical stem of the reinforced prestressed beams is reinforced concrete.

According to another variant, the vertical stem of the reinforced prestressed beams is made of reinforcing bars to which the distribution reinforcement is fixed.

The filling elements are made of thermal insulation material or of material from the group of plastic, pressed sawdust.

The advantages of the floor slab, according to the utility model, consist in the achieved reduction of the amount of monolithically poured concrete while maintaining the required load-bearing capacity, while reducing the total weight of the building. The construction process has been significantly accelerated, creating an opportunity for quality thermal insulation.

Example implementation of the utility model

The floor slab includes a distribution reinforcement 1 connected to load-bearing vertical elements 2 and covered by monolithically poured concrete 3. According to the utility model, the floor slab also includes parallel and spaced reinforced prestressed beams 4, whose reinforcement 5 is connected to the load-bearing vertical elements 2. The distance between the reinforced prestressed beams 4 and their reinforcement 5 are determined by the load on the floor slab and the distance between the supporting vertical elements 2, according to the knowledge of those skilled in the art. The connection of the reinforcement with the supporting vertical elements 2 is performed according to any of the known and applied in the construction schemes, for example by the reinforcement of the connected elements with subsequent monolithing. The reinforced prestressed beams 4 have a reverse T-section with a lower horizontal flange 41 and a vertical stem 42. Between the reinforced prestressed beams 4 are filling elements 6 mounted to their lower horizontal flange 41. Covered by monolithically cast concrete 3, distributor of reinforcement 1 is located above the reinforced prestressed beams 4 and the filling elements 6.

The filling elements have an upper surface 61 located lower than the upper end of the reinforced prestressed beams 4 to ensure the joint operation in the operating conditions of the elements of the floor slab. The specified difference in heights during the installation of the filling elements 6 can be determined, already in the design process, depending on various factors such as: diameter of the reinforcing bars, grain size of gravel for monolithically poured concrete, etc. It is recommended to be at least 1 cm.

The vertical stem 42 of the reinforced prestressed beams 4 can be made of reinforced concrete, according to the embodiment shown in Figure 1 to Figure 3, or formed, as shown in Figure 4, from reinforcing bars to which the distribution reinforcement 1 is fixed.

Depending on the specific design and requirements for the building, the filling elements 6 can be of different materials.

According to the exemplary embodiment shown in Figure 1, Figure 2 and Figure 4, the material of the filler elements 6 is thermally insulating. Thus, high-quality thermal insulation of the floor and / or the building is provided, as it is not necessary to perform additional thermal insulation works. At the same time, the filling elements 6 of thermal insulation material are also corrugated elements. The lower surface of the filling elements 6, as a variant shown in figure 2, is flush with the lower surface of the reinforced prestressed beams 4. According to another embodiment shown in figure 4, the lower horizontal flange 41 of the reinforced prestressed beams 4 is covered of the filling elements 6 of thermal insulation material, avoiding any thermal bridges in the floor slab.

According to the exemplary embodiment shown in Figure 3, the material of the filler elements 6 is of a type whose load-bearing capacity is sufficient to serve as a corrugated element. Such material may be from the group of plastic, pressed sawdust and others. Typically, in this embodiment, the filling elements 6 are trough-shaped, as shown in the figure, but can also be hollow with a closed contour. This option is applicable in cases where it is not necessary to provide thermal insulation.

The filling elements 6 and the space occupied by them can be used for installation of various types of installation elements required for the equipment of the building, such as: hot and cold water pipes, sewer pipes, corrugated pipes, power cables, etc.

Use of the utility model in industry

The floor slab can be applied in different storeys of buildings, as well as in different methods for construction of the vertical load-bearing elements of the buildings. In addition, the reinforced prestressed beams 4, dimensioned for the respective site, are produced outside the construction site № 03.2 / 30.03.2018 Descriptions to certificates for registration of utility models 651 on the landfill or in factory conditions. The filling elements 6, regardless of their type and material, are also produced outside the construction site, mainly in factory conditions.

All necessary elements are performed on the construction site, on which the respective floor slab is planned to be executed and in particular the bearing vertical elements 2 such as bearing walls, earthquake washers, elevator shafts, bearing beams, etc. The reinforced prestressed beams 4 are mounted on them, connecting their reinforcements 5 with the bearing vertical elements 2. The filling elements 6 are mounted, and depending on the specific location of the floor slab, they can be heat-insulating or not. On the installed reinforced prestressed beams 4 and filling elements 6 the reinforcement provided by the project, including the distribution reinforcement 1, is placed, the respective connections are made and the concrete 3 is poured.
