Description
Technical field
The present invention relates to transformer substation foundation facilities protection device, specifically a kind of transformer station power distribution equipment steelframe suspension column protective cap.
Background technology
Transformer station's power distribution equipment structure (propping up) frame can be divided into steel work and concrete structure by material.Raising along with national macroeconomic strength and transformer substation voltage grade, structural meterials at transformer station's power distribution equipment structure (propping up) frame is selected, when considering safety, also need to consider the agility of economy, processing and manufacturing and the construction of structure, the aesthetic property of end product quality etc.
Along with China's rapid development of economy, the output of steel of China also increases substantially thereupon, and only in 2005, the annual output of steel of China is 3.42 hundred million tons of left and right, accounts for the nearly 1/3 of Gross World Product, becomes steel outlet big country.The quality of China's steel is also steadily improving, and simultaneously the market price also is tending towards rationally, and therefore in the last few years, in power transformation structure (propping up) shelf structure of 110 kilovolts and above, the equipment structure support of the centrifugal rod type of employing steel concrete was fewer and feweri.
The structure of steel structural form (propping up) frame be applied in recent years in obtained development at full speed.Steel structure (propping up) frame and basic type of attachment are divided into rim of a cup plug-in type and two kinds of forms of bolt connecting type; technological requirement due to transformer substation construction; structure (propping up) frame basis end face absolute altitude is generally lower than ground 200mm; suspension column part steel work is easily corroded by the surface water in soil if do not done protection; the way of GPF (General Protection False cap is the cast-in-place form of plain concrete, and site operation is more difficult.
Summary of the invention
Technical problem to be solved by this invention is to overcome the defect that above-mentioned prior art exists, and a kind of transformer station's power distribution equipment steelframe suspension column protective cap of each parts easy accessibility is provided, and to reduce difficulty of construction, shortens construction period, improves the recovery utilization rate of resource.
For this reason; the present invention adopts following technical scheme: a kind of transformer station power distribution equipment steelframe suspension column protective cap; comprise the plastic cap body; it is characterized in that; described cap body is formed by two and half cap body left and right sealing docking; the locating hole of center formation one be used to being tightly connected of cap body upper surface; the upper surface of each half cap body forms half described locating hole; on the upper surface of one of them half cap body, have one for toward the cap intracoelomic cavity, injecting the screwdown greaser of butter, the screwdown greaser place connects a seal.
When the present invention uses, by the butter that injects the cap intracoelomic cavity, transformer station's power distribution equipment steelframe suspension column is carried out to anti-corrosion protection; Cap body by sealing carries out waterproofing protection to steelframe suspension column and the butter of cap intracoelomic cavity; For locating hole and the steel frame columns be tightly connected, be sealed and matched, reach the sealing of both junctions.
Structure of the present invention can make each ingredient adopt on-the-spot mold processing, on-the-spot mounting means to complete, and has changed conventional concrete protective cap site operation difficulty large, the shortcoming that the later maintenance replacement cost is high.The present invention can adopt the clamping mounting means to be arranged on transformer station's power distribution equipment steelframe suspension column, remove all more convenient, well utilized the characteristic that Steel structure equipment structure (propping up) frame is easy to assemble, replacing is easy, can effectively reduce transformer station in the later stage workload during exchange device structure (propping up) frame more, shorten construction period.
Further, on the hole wall of two interfaces on one of them half cap body top and half locating hole, be embedded with the rubber fastening band of a continuous horizontally set; On the hole wall of half locating hole on another half cap body top, also be embedded with the rubber fastening band of a continuous horizontally set, two interfaces on this half cap body top also respectively have the waterstop expansion slot of a horizontally set; In 2 and half cap bodies whens docking, the rubber fastening band of the interface on half cap body top is placed in the waterstop expansion slot on second half cap body, makes the interface place on half cap body top reach the purpose of waterproof.
Further, during two and half cap body docking, the rubber fastening band that is positioned at locating hole forms a sealing collar in the same plane, has further improved the sealing of locating hole and steelframe suspension column junction.
Further, outside the docking section, both sides that two and half cap body docking form, equal clamping one is positioned at the connection card article on the external sidewall of cap, and two and half cap bodies combinations after making to dock by the connection card article firmly; The height that connects card article is consistent with the height of docking section, makes the combination of two and half cap bodies more firm.
Further, the docking section of described two and half cap bodies is adopted vertical convex tendon and is connected with the close-fitting longitudinal fluting of vertical convex tendon, and during two and half cap body docking, vertically convex tendon is placed in longitudinal fluting; Described rubber fastening band and waterstop expansion slot all are positioned at the inboard of vertical convex tendon and longitudinal fluting.
Further, on described connection card article, form one be used to holding the draw-in groove of vertical convex tendon and longitudinal fluting, two and half cap bodies after utilizing draw-in groove to make to connect card article will to dock are combined as a whole.
Further, the connecting sewing formed between the butt joint that described two and half cap body docking form and connection card article and docking section all is filled with water-tight glue, has effectively improved the sealing of cap body.
Further, described seal is bolt, and bolt is standard component, and the cost of seal is low, easy to process.
Further, the bottom opening of described cap body, lower surface is plane, is plane lower surface and the platform of steel frame columns foot bottom and is used in conjunction with.
Further, described cap body is up-small and down-big stage body shape, the good stability of cap structure.
Suspension column protective cap each several part of the present invention can be by on-the-spot mold processing, on-the-spot installation, easy accessibility; Have globality and watertightness preferably, on-the-spot installation procedure is simple, and the later stage can safeguard that convertibility is high, and resource recovery is high, has effectively saved the transformer substation construction overall life cycle cost.
