The invention relates to the field of construction, in particular to designs floating roofs used in vertical tanks for storage of oil and volatile oil. The design of the floating roof includes a box-shaped pontoons with shutter, diaphragm and prigozy. The membrane is made with the supporting poles and radial beams are rigidly connected with the peripheral box-like pontoons located below the membrane. Legs are attached to the radial beams and prigozy placed along these radial beams. The technical result of the invention is to improve the stability of the floating roof, the improvement of its operational properties. 2 C.p. f-crystals, 2 Il.
The invention relates to the construction of reservoirs, in particular to designs floating roofs used in vertical tanks for storage of oil and volatile oil.
Known floating roof tanks for oil and petroleum products (see model projects 704-1-183.86 704-1-190.86), the design of which has a Central single-layer membrane, the peripheral box-like pontoons and the support legs fixed in the membrane and boxes.
Cesti and depression, in which accumulated precipitation, which degrades performance of the roof leads to a gradual podlasian support stands when lowering the roof in the down position (on the rack).
Known designs of floating roofs in which to improve the form of the Central membrane on its surface are prigozy in the form of segments of pipe filled with sand or concrete blocks (see model projects 704-1-187.86704-1-189.86). However, as practice has shown the operation of such constructive design of roofs little helps maintain the conical shape of the membrane. In this case also the danger of pontaniana support stands fixed in the flexible membrane, when lowering the roof in the lower position resting on the bottom of the tank.
In the above-mentioned standard projects (see also reference the designer "Metal structures", ed. DIA, 1998, S. 410-411) to improve the form of the flexible membrane to the outside surface of the welded radial ribs. However, the legs were fixed only in the membrane, and additional rigidity radial ribs has not been used, and preserved all the disadvantages of the known odnomesnyh roofs.
Known rasl roofs, compared to odnoletnii roofs, 1.5-2 times higher, and the number of welds required for their installation can exceed the length of the weld seams of the hull of the tank.
Closest to the proposed solution to the technical essence is the design of the floating roof, including pontoons, steel diaphragm and weights (see ed. mon. 563469, class E 04 H 7/02; 66 D 87/18 from 17.03.1976 year).
In this decision, as the weights proposed to use concrete disc with a Central hole. The membrane also has a Central opening, the edges of which are sealed and connected with the edges of the holes in the concrete drive. In practice, this solution was not used due to the large complexity of installation of heavy concrete drive. In addition, the roof structure does not solve the problem of fixing posts in the flexible membrane in the presence of concrete drive.
The proposed floating roof differs in that its membrane is made with the supporting poles and radial beams are rigidly connected with the peripheral box-like pontoons and placed under the membrane, and the support legs are attached to the radial beams and prigozy placed along these radial beams.
Prigruzka solution is to increase the stability of the floating roof, improving its performance properties, including the effectiveness of storm water drain and extension of service without incurring excessive costs of metal and complexity of installation.
The invention is illustrated by drawings, where Fig.1 shows a plan of the floating roof; Fig.2 - section a-a in Fig.1.
Floating roof vertical tank consists of a peripheral box-like pontoons 1, shutter 2, the membrane 4 with radial beams 3, the support legs 5, which are attached to the radial beams 3.
In Fig. 2 shows that part of the support legs 5 is equipped with prigrozili 6. Prigozy 6 can be attached directly to the radial beams 3 or posted on the membrane 4 along the radial beams 3. In the drawings, it is shown that in the center of the roof has a hole 7 for the removal of water from the roof through the gutter system 8 out of the tank with the wall 9 and the bottom 10.
Radial beams 3 are rigidly connected to the peripheral box-like pontoons 1 and have a bias toward the center of the floating roof. The membrane 4 is connected with the radial beams 3, for example, by means of welded sealed seams, so the entire surface of the membrane 4 has a slope towards the center of the roof that provides guaranteed removal of precipitation as rain catechesi afflux of stored product curves a membrane 4 and through her influence on the radial beams 3, creating in them bending moments, which arches radial beams 3 against the design slope. To compensate for this effect, without increasing the cross section of the radial beams 3 are prigozy 6 arranged along the radial beams 3. Prigozy 6 can be placed on a part of the support legs 6, as shown in Fig.2, or be attached directly to the radial beams 3, or be placed on the membrane 4 along the radial beams 3 (not shown). Prigozy 6, thus, provide the necessary stability of the floating roof design and the slope of the membrane 4 to the center of the roof and reduce the consumption of steel in radial beams 3. The number of prigroziv 6, their weight and placement are calculated depending on the diameter of the tank, size of the design slope of the membrane 4 to the center of the roof and the density of the stored product. The total weight of prigroziv can reach several tens of tons, so they can gain from separate elements that can manually submit into the tank through the manhole 600 mm during installation of the floating roof without the use of lifting devices or install prigozy 6 on the membrane 4 along the radial beams 3 enlarged elements with rganizovannoy the drain to the center of the floating roof.
Known agnodice floating roof with peripheral box-like pontoons quite difficult to install, since in the bottom of the tank must first be laid in the Central membrane and connect it with the pontoons, partially fill the tank with water, mounted to the pontoons with the membrane was afloat, and only after that to mount the legs, it is very difficult to provide a design slope of the membrane to the center.
The proposed construction of floating roof vertical tank allows you to simplify its installation due to the presence of radial beams 3, rigidly connected with the peripheral box-like pontoons 1, due to the fact that boxes 1 with radial beams 3 are mounted on the supporting posts 5 at the desired elevation relative to the bottom.
Radial beams 3 are mounted on the supporting posts 5 with the necessary design bias toward the center of the roof and only after reconciliation mounted boxes 1, radial beams 3 and supporting racks 5 stacked on top parts of the membrane 4, which is hermetically attached to the radial beams 3, for example, by welding.
The proposed construction of a floating roof, thus, can significantly improve its shape, providing garantirovanno along the radial beams 3, allow to improve the stability of the floating roof and to maintain the desired surface of the membrane 4 in the position of the roof afloat without excessive costs of metal on the radial beams 3.
In the lower position of the floating roof when its resting on the bottom 10 of the tank through the support legs 5, the shape of the membrane 4 is also not distorted, because the rack 5 is attached to the radial beams 3, which are rigidly connected to the peripheral box-like pontoons 1.
Such a rigid roof structure allows to provide its bearing on the base plate 10 through all of the support legs 5, because they retain their vertical position.
Claims 1. Floating roof vertical tank containing peripheral box-like pontoons with shutter, diaphragm and prigozy, characterized in that the membrane is made with the supporting poles and radial beams are rigidly connected with the peripheral box-like pontoons and placed under the membrane, and the support legs are attached to the radial beams and prigozy placed along these radial beams. 2. Floating roof vertical tank under item 1, characterized in that prigozy installed on part of the support struts of the roof. 3. Floating cover
