Description

(54) Reinforced horizontal fiberglass winding vessel.

The subject of the invention is a reinforced horizontal fiberglass coil vessel.

The method of storing the container is one of the parameters that significantly influence the dimensioning of the entire container. Most often, it is used to mount on two or more seat supports. In this way, local deformation occurs at the support points, the vessel as a whole bends and changes its circular cross-section, resulting in stress peaks in the vessel walls due to both primary stresses from the load itself and secondary stresses due to shape changes cross-section. In plastic containers, these phenomena are much more pronounced than in steel containers, and the resulting stresses are more dangerous. In order to prevent such deformations from occurring in plastic containers, the seats are made wide with a large wrap angle, larger wall thicknesses are selected, or the containers are reinforced with thick circular ribs, sandwich construction of the container wall is provided, or the containers are provided with a whole system of reinforcing ribs. For the same reasons, the containers are also placed close to the fronts, which at least to some extent provide a circular cross-section at the location, although this method is not statically optimal. The result of all these phenomena is that the structure is made more expensive either by increasing the wall thickness of the container or by producing costly reinforcements, the formation of plastic reinforcements being poorly effective due to the low modulus of elasticity of these materials. The use of massive metal ribs encounters numerous technological difficulties in connection with the container, increasing the weight of the container during manufacture, and complicating the manufacturing process.

These disadvantages are overcome by the reinforced horizontal fiberglass container according to the invention, which is characterized in that it is provided with laminated fastening flanges with connecting legs at the mounting points, by means of which the container is fastened, for example, by bolts to supporting rigid frames. . These rigid support frames have a moment of inertia of the cross-section considerably greater than the fastening flanges with the connecting legs. This solution both maintains the circular cross-section of the container at the location of the container and substantially reduces the technological difficulties associated with manufacturing the container and reinforcing elements, i.e., rigid support frames and fastening flanges with connecting legs. lower wall thickness.

For example, the rigid support frame is made of metal or concrete with a high moment of inertia and is manufactured separately and, either alone or in conjunction with another structure, constitutes a support for the container following the foundation. The fastening flange with the connecting legs with low moment of inertia is laminated to the surface of the container, thereby firmly attached to the container. These reinforcing elements are connected to each other either directly or via other connecting parts, for example by screwing. The low flexural stiffness of the fastening flange allows it to be easily wrapped on the container, for example, by wrapping it into the container surface with a sufficient layer of glass laminate. It is therefore not necessary to fit the fastening flange! as a closed circular ring, which is very advantageous in terms of production technology.

The rigid supporting frame is dimensioned according to standard calculations to ensure the required rigidity of the vessel cross-section. The fastening flange with the connecting legs is designed essentially only for the transmission of relatively small radial forces and, unlike the conventional stiffeners associated with the vessel, which require the maximum moment of inertia of their cross-section, the bending stiffness is not required for its function.

An essential feature of this design is that, in the reinforcing elements, both the function and the support are separated from the function of the connection to the vessel, which simplifies the process; It enhances the manufacturing technology of the vessel itself and allows for a better connection of the metal parts to the laminate vessel and also allows the design of vessels with smaller wall thicknesses, which saves on material and reduces the cost of the vessels.

The attached drawing shows schematically examples of a reinforced horizontal fiberglass winding vessel and its reinforcing elements according to the invention, wherein in Fig. 1 is a longitudinal section of the vessel with reinforcing elements, Fig. 2 is a cross-section of the vessel before winding the fastening flange. Fig. 3 and Fig. 4 show two ways of joining the free ends of the fastening flange.

On the fiberglass container 11 (Fig. 1), the fastening flange 2 with the connecting legs 3 is laminated by additional rewinding of the fiberglass layer 4, by means of which the fiberglass container 1 is fastened by screws to a rigid support frame as a separate element which construction.
