Description

Utility Model Technical Area

This utility model relates to building formwork that are mounted before pouring concrete and are used to hold concrete and provide drying of the concrete, and which are mounted and maintained in the mounted state for some time after drying the concrete.

The present utility model relates to the production of said formwork forms based on flexible PVC having walls that will ensure uniform load distribution over them.

Utility Model Backgrounds and Known Technical Issues

Currently, concrete is poured during construction after installing the formwork forms of the girth of the floors and the completion of the laying of steel reinforcement. After some time, the formwork forms of the ceilings are dismantled, walls are erected and plastering works are carried out, as well as other construction works.

Typically, wooden and metal formwork are used as formwork forms of floors.

Formwork made of metal, preferably wood in terms of durability; however, the water contained in the coating causes corrosion of these formwork forms. For these formwork forms, corrosion is an undesirable situation. Only one side of these formwork is in contact with the coating; the other side does not allow an alternative

use. Since they are heavy, their transportation and carrying is heavier and more expensive compared to wooden forms. It is impossible to cut and change the shape of metal formwork, as in the case of wooden forms. Therefore, when the formwork form becomes unusable, it may be necessary to supplement some of it with elements of a wooden formwork. Therefore, users of metal formwork should also have a certain number of wooden formwork.

Wooden formwork does not have some of the above disadvantages. For example, they are lighter in comparison with metal ones; their transportation and carrying are easier and do not create any problems, as in the case of metal forms. Since they can be cut and their sizes can be changed, they are suitable for any size.

The disadvantage of wooden formwork is the operation of coating the surface of the formwork with tar before pouring concrete. This additional step prevents concrete from adhering to the mold surface. Since the coating contains water, wooden formwork swell and deform over time. Deformation of surfaces leaves permanent marks on concrete. To remove these marks, a thick layer of plaster is required. The result of this is an unjustified increase in value.

Sometimes, due to the uneven distribution of the load, the formwork cracks or breaks after pouring concrete. Effectively, you can use only one side of the formwork form - whether it is wooden or metal.

The problems that a real utility model is designed to solve, and solutions

The purpose of this utility model is to solve the above problems. In order to achieve this goal, it is proposed formwork, which has smooth surfaces, the mass of which is much less than

metal or wooden forms, which has the proper design to distribute the load along it, and which can be cut if necessary to amend the dimensions.

A construction formwork made of PVC with a flat surface is proposed. The outer surface of the formwork form (which will be in contact with concrete during pouring) can be provided smooth so that no permanent marks remain.

In one preferred embodiment of the utility model, a second flat surface is provided parallel to said flat surface. Moreover, the secondary surface does not require any secondary process (tar coating, etc.), and, therefore, the service life of the formwork is increased.

In one preferred embodiment of the utility model, walls are provided between the upper and lower levels. Vertical walls extend from one flat surface to another perpendicularly. Horizontal walls extend from one surface to another at certain angles. Thanks to these walls, damping of the load after pouring concrete is achieved.

Detailed Description of the Utility Model by the Example of Embodiment

A utility model relates to a construction formwork (1). The formwork form (1) was obtained by extrusion from a material based on PVC. On the upper and lower levels of the construction formwork form (1), flat surfaces (2) are provided. The surface onto which concrete will be poured is made using several building formwork forms (1) side by side.

Figure 1 is a General view of the proposed construction formwork form (1). There are walls (3) designed to bear the load that will arise after pouring concrete between the upper flat surface (2.1) and the lower flat surface (2.2).

These walls (3) are provided in order to bear horizontal and vertical loads and to prevent damage to the formwork form (1) by these loads. The lower and upper surfaces (2.1, 2.2) of the walls (3) are interconnected. The lower and upper surfaces (2.1, 2.2) are parallel. Walls (3) are provided as vertical walls (3.1) and horizontal walls (3.2). Vertical walls (3.1) pass from one flat surface (2) to another at an angle of 90 degrees, and horizontal

walls (3.2) pass from one flat surface (2) to another at a certain angle. This certain angle is preferably 45 degrees.

The utility model is not limited to the above explanations. It is clear that many changes in terms of size and construction are possible, but the basic idea of a PVC-based formwork form containing at least one flat surface remains unchanged.

Claims (5)

1. Construction formwork form (1), characterized in that it is made of PVC and has at least one flat surface (2). 2. Construction formwork form (1) according to claim 1, characterized in that it contains a second flat surface (2.1, 2.2) parallel to the specified flat surface (2). 3. Construction formwork form (1) according to claim 2, characterized in that it contains walls (3) provided between the upper flat surface (2.1) and the lower flat surface (2.2). 4. The construction formwork (1) according to claim 2, characterized in that it contains vertical walls (3.1) extending from one flat surface (2.1, 2.2) to another (2.1, 2.2) perpendicularly. 5. The construction formwork (1) according to claim 2, characterized in that it contains horizontal walls (3.2) extending from one flat surface (2.1, 2.2) to another (2.1, 2.2) at a certain angle.
