Detailed Description

The present invention will be further explained with reference to the accompanying drawings:

a500 kV transformer substation HGIS power distribution device framework with a cross-type cable support supporting system as shown in figures 1-2 comprises a framework main body 5 and a subsection framework 4 arranged in the middle section of the framework main body 5. The framework 4 at the subsection comprises a latticed steel beam 6 arranged transversely, a left latticed steel column 7 and a right latticed steel column 16 respectively and vertically arranged below the left end and the right end of the latticed steel beam 6, and a cross-type inhaul cable supporting system arranged between the left latticed steel column 15 and the right latticed steel column 16. And a framework gusset plate 8 is respectively arranged on the rear side walls of the upper ends of the left lattice type steel column 7 and the right lattice type steel column 16. The power distribution device framework is in a straight line shape and comprises a row of frameworks, wherein the row of frameworks are formed by sequentially connecting a plurality of framework beams and framework columns, adjacent framework columns and framework beams can form a unit which can also be called a subsection, and therefore the row of frameworks is formed by a plurality of units or subsections. Generally, the 500kV HGIS comprises more than 6 sections, when a row of frameworks comprises odd sections, a cross-type guy cable supporting system can be arranged at the middle section, when even sections are arranged, the number of the sections is 2n, n is a positive integer, and the cross-type guy cable supporting system can be arranged at the n +1 th or n-1 th position.

The crossed inhaul cable supporting system comprises an inhaul cable I and an inhaul cable II which are arranged in a crossed mode. In order to ensure enough lateral supporting force, the bottom of the lateral support needs to keep a certain distance with the bottom of a frame column, which is generally not less than one seventh of the height of the frame column, so that the bottom of the inhaul cable needs to keep a certain distance with a column base, and the distance between the column and the column is limited, so that the inhaul cable is crossed, the length of a row of frames is reduced, and the purpose of reducing the floor area is achieved. The first stay cable and the second stay cable are identical in structure and respectively comprise a steel strand 11, an upper steel strand anchorage device 10 connected with the upper end of the steel strand 11, an anchorage device node plate 9 connected with the upper steel strand anchorage device 10, a lower steel strand anchorage device 12 connected with the lower end of the steel strand 11 and an anchoring steel plate connected with the lower steel strand anchorage device 12. The anchor node plates 9 are detachably connected with the framework node plates 8. The anchor steel plate is embedded in the frame column foundation 15. In fig. 1, a node one 2 represents a connection point between the cross-type cable support system and the lattice-type frame beam and the lattice-type frame column. And the second node 3 represents the joint of the crossed cable support system and the frame beam column foundation. The lower ends of the left lattice type steel column 7 and the right lattice type steel column 16 are fixed in the framework column foundation 15.

Further, a first mounting hole is formed in the framework gusset plate 8; and a second mounting hole is formed in the anchor device node plate 9. The framework gusset plate 8 is connected with the anchor gusset plate 9 through bolts. For the convenience of linking to each other between cable and the framework, the cable needs link to each other with the node of lattice formula girder steel and lattice formula steel column, is used for bearing the horizontal thrust that the framework received, if lug connection on the framework, needs the trompil to produce the damage to former frame construction, therefore sets up the framework node board, makes things convenient for the installation of cable, still can set up the not framework node board of equidimension according to the thickness of cable simultaneously, and the installation is used comparatively in a flexible way. The cross-type inhaul cable supporting system is for increasing the lateral stability of framework, and the inhaul cable mainly bears the horizontal force of framework, and the upper end of inhaul cable, ground tackle gusset plate and framework gusset plate adopt bolted connection to be articulated in order to form, and articulated be in order that this place node atress remains unanimous with the direction of inhaul cable all the time, have increased the fastness of node, and use bolted connection to make the node have better intensity, and be convenient for construct.

Furthermore, the small size of the upper steel strand anchorage device is inconvenient for bolt connection, and the anchorage device node plate needs to be rigidly connected with the steel strand anchorage device, so that the anchorage device node plate 9 is welded and connected with the upper steel strand anchorage device 10.

Further, as shown in fig. 3 and 4, the anchoring steel plate comprises a steel plate 13 and a plurality of steel bars 14 uniformly distributed at the bottom of the steel plate 13; the reinforcing steel bar 14 comprises a first reinforcing steel bar section vertically connected to the bottom of the steel plate 13 and a second reinforcing steel bar section vertically connected to the outer side of the lower end of the first reinforcing steel bar section. As can be seen from fig. 4, a reinforcing bar 14 is connected to the lower of each of the four corners of the steel plate, and there are 4 reinforcing bars in total. The diameters of the first reinforcing steel bar section and the second reinforcing steel bar section are the same, d is set, and the sum of the lengths of the first reinforcing steel bar section and the second reinforcing steel bar section is larger than 40d, wherein d is a positive number. Have sufficient intensity in order to guarantee the node of two cable lower extremes, ensure that cable lower extreme node can not take place to destroy earlier than the cable, the utility model discloses an anchor steel sheet is fixed the lower extreme embedding of two cables in the framework column foundation, can provide sufficient bearing capacity for the cable like this, guarantees the lateral stability of framework. Steel sheet among the anchor steel sheet is for becoming a whole with steel strand wires ground tackle welded connection down, the cable can receive along the ascending power of self direction, produce the effect of drawing to its lower extreme node, steel strand wires ground tackle and steel strand wires easily produce with the concrete and slide and be pulled out the concrete down, the anchor reinforcing bar can firmly be fixed the anchor steel sheet in the framework column foundation, anchor steel sheet becomes an organic whole with steel strand wires ground tackle down, thereby ensure that steel strand wires and steel strand wires ground tackle down can not pulled out the framework column foundation, the intensity of node here has been increased, thereby can provide sufficient bearing capacity for the cable. The anchoring effect of the steel bar is positively correlated with the length of the steel bar, the longer the length of the steel bar is, the better the anchoring effect of the steel bar is, the node is less prone to being pulled out of the foundation to be damaged, and the size and comprehensive consideration of the foundation are taken into consideration to provide the regulation of being larger than 40 d.

The above-mentioned embodiments are only for describing the preferred embodiments of the present invention, and are not intended to limit the scope of the present invention, and various modifications and improvements made by those skilled in the art without departing from the design spirit of the present invention should fall into the protection scope defined by the claims of the present invention.
