Reinforced concrete products anchor plates AP-1 are used in railway construction in cases of newly erected or reconstructed cantilever supports of the contact network, which are installed on complex sections and sections of railway tracks, for example, at large railway interchanges, on side and main tracks, in the necks of stations with lots of ways. The structures of cantilever supports have the most important advantage compared to other types of power transmission line supports - the absence of a mechanical connection between the suspensions of adjacent tracks. However, this advantage leads to an increase in the longitudinal and transverse loads experienced. Three-beam foundations with anchor fastening can significantly reduce the effect of these loads, due to three foundation beams, which evenly distribute and transfer loads to the ground, and the whole structure is rigid, providing the necessary margin of safety.
The foundation material - reinforced concrete - has significant advantages over other building materials: reinforced concrete structures are not subject to deformation; equally successfully resist both stretching and compression; high rates of strength and durability make it possible to use it in any corner of the globe, in any climatic conditions. Anchor plate products AP-1 are used in areas with aggressive climatic conditions, with an estimated outdoor temperature below -40 ° C, in ordinary soils and heaving soils of deep seasonal freezing, in areas with seismicity up to 9 points inclusive, with non-aggressive, weakly, medium and highly aggressive degree of aggressiveness of the environment.
Structurally, three-beam foundations include the upper glass and lower three-beam parts. The upper part is a reinforced concrete head with a square section of 670x670 mm, with a cylindrical cavity with a diameter of 530 mm, a depth of 800 mm or 1200 mm for installing pillars. The lower part has a three-beam section with the beams in plan at an angle of 120°. The beams have a wall thickness in the extreme upper part of the beam of 80 mm, and at the point of convergence of the beams - 90 mm. The connection of the upper glass and lower three-beam part is carried out in the form of a pyramid.
Reinforced concrete products anchor plates AP-1 are made according to one of three series: series 3.501.1-149 issue 2 "Foundations for centrifuged reinforced concrete supports of the railway contact network", series 3.501-130 or working drawings 4182I, exclusively from heavy concrete of increased density. Railway construction prescribes the use of high classes of concrete - for compressive strength - B30, for frost resistance - F200 and water resistance - W6 - allow the most efficient use of three-beam foundations in areas with unstable climatic conditions and in areas where the outdoor temperature reaches -50 ° C and below.
Anchor plate products AP-1 are reinforced with frames made of hot-rolled rod reinforcement of classes A-III (basic option) and A-II (additional). The main reinforcement at the design temperature of the outside air up to -40 ° C is carried out with reinforcement made of steel 25G2S in welded frames, grade 35GS - in knitted frames. At temperatures below -40°C, only 35G2S steel in knitted frames is used. Reinforcement according to an additional option is carried out at an estimated winter temperature of the outside air below -40 ° C with reinforcement made of steel grade 10GT in welded frames, steel grade VSt5 sp2 - in knitted frames. Instead of reinforcement of class A-III brand 35GS, it is possible to use reinforcement At-III C in accordance with GOST 10884-81 without recalculating the area of \u200b\u200bthe rods. The spiral in the foundations is taken from an ordinary reinforcing wire of a periodic profile of class Vr-1 according to GOST 6727-80. Other fittings are used from ordinary reinforcing wire of a periodic profile of class VR-I according to GOST 6727-80 and fittings of class A-I grade VSt3sp2 according to GOST 5781-82. Slinging loops are made of class A-I fittings of grade VSt3sp2 according to GOST 5781-82. All reinforcement elements and embedded products of three-beam foundations are covered with anti-corrosion and waterproofing compounds.
Slinging of products is carried out using holes and sling loops, which, after installing the foundations in the base soil, are cut off from the concrete surface. The cut points are then necessarily covered with waterproofing.
Being products that are used not only in the middle, but also in the northern latitudes, in areas not only with a temperate, but also with an aggressive climate, AP-1 anchor plates must meet the most stringent product quality requirements. Control is carried out at all stages of manufacturing products. Even a minor defect can lead to displacement of the support and, ultimately, to the destruction of the power line structure. Therefore, the foundations should not have cracks, defects in the concrete surface. Shrinkage cracks on the surface of products should not be wider than 0.1 mm. Shells, sags and chips in large quantities are not allowed. Reinforcement exposure is strictly prohibited.
Anchor plate AP-5 for installation of busbar portals for outdoor switchgear 500 kV– a monolithic slab of a special shape, which is designed for fastening guys in steel portals of 500 kV outdoor switchgear. Anchor plates for fastening supports on guys have a trapezoidal section - a form of a reinforced concrete rectangle with a rib in the center.
The massive slab is designed to increase the area of support and ensure the stability of the foundation in areas of weak soils. In addition, anchor plates according to the 3.407-102 series are sold together with mushroom-shaped foundations and outdoor switchgear supports. For fastening guys in the ground, the slab is securely buried in the ground on a sandy base. Design drawings and calculation diagrams are provided by Series 3.407-102.
The main tasks of the plate AP.5:
- Fastening guys
- Fixing anchor bolts
- And as a result, fixing the power transmission line support of a steel or reinforced concrete type, followed by overcoming wind, pull-out and dynamic loads.
How to buy high-quality anchor plates? Let's start with the specific requirements for concrete:
- Slabs buried in the ground must be waterproof and frost-resistant (F200);
- Plates must successfully pass tests for strength, stiffness and crack resistance;
- The geometry and reinforcement of the plates must comply with the requirements of series 3.407-102.
- Anchor plates should not have cracks, reinforcement exposure, deep chips and shells.
- Each plate must be marked in accordance with the requirements of state standards, the mass of the plate and the date of manufacture.
Guys are fastened through elongated Y-shaped anchor bolts to anchor plates, the installation location of which is given in the project. Plate designed in series 3.407-102, is made of medium-resistant concrete of heavy grades M200-M400, which, due to additives, has a reduced permeability. Modern construction is interested in modified materials that will allow slabs to last much longer than conventional reinforced concrete products. Therefore, special additives and hydrophobic compounds are used to improve the quality of anchor plates.
Reinforced concrete foundation elements with a protective layer thickness of less than 30 mm, installed in soils with an aggressive environment, must have reliable waterproofing. The mass of the anchor plate AP-5 is 7250 kg, lifting is carried out using the mounting loops included in the design.
The production of anchor plates is not an easy process, it can only be carried out by an experienced manufacturer who strictly follows the letter of international and domestic standards. An analogue of the AP.5 plate is the PAZ plate, which is also used in substation and network construction. Deliveries of anchor plates are carried out throughout the country, regardless of the location of your facility. You can order anchor plates in any configuration directly on our website. In addition, together with portal slabs, you can buy other reinforced concrete products for network construction: power line racks, universal racks, supports, etc.
