Abstract
The invention discloses a sliding support for a large power transformation structure frame composed of at least vertical and horizontal two spherical supports respective joint with the sliding plates of the bottom and lateral. At least a cover board is arranged on the spherical support and at least one side of the cover board and the sliding plate is respectively connected with a frame pole and a beam principal end plate. The spherical support comprises a graphite plate connected with the sliding plate, a spherical bearing on the cover board is connected with the graphite plate by a sliding disk. Bolt holes are arranged on at least one side of the sliding plate, bolts are connected with the frame pole, while bolt holes are also arranged on at least one side of the cover board and connected with the beam principal end plate, which together constitutes of connecting components of the main body. The sliding support has advantages of simple structure, convenient installation and independent sliding support inwhich the beam can again erected just after arranging the sliding support on the improved pole joints plate basically without changing the original mounting means.
Description
Technical field
The present invention relates to be a kind of be used for the design of large-scale framework in the electric substation, to solve the sliding support of large-scale power transformation framework temperature stress.
Background technology:
The above electric substation of 220kV grade, modal form is that the outdoor open type of equipment arranges that framework at this moment often be designed to elongated bent structure form, and entire length is bigger for satisfying technological requirement.
Variations in temperature can make object expand with heat and contract with cold, and at the length direction of trussed member, because the accumulation of length direction, it is especially outstanding that the absolute deformation value seems.When the hold-down support restriction was arranged in bar section end, the bar section can not produce distortion, just is converted into rod member internal force, is called temperature stress.Stipulate according to " electric substation's Architectural Structure Design technical stipulation " 3.3.4 bar: " continuous bent of rigid support is established at two ends, when its length overall above 150 meters; Or be continuous rigid frame, when its total length surpasses 100 meters, should consider the influence of temperature action.”
By calculating relatively: with the 750kV framework is example: when adopting three Span Continuous frameworks (framed bent length overall 135m), temperature action is less to the influence of framework, the control operating mode of framework length travel is the strong wind operating mode, that is to say that the length travel of framework is not controlled by temperature action; When adopting five Span Continuous frameworks (framed bent length overall 225m), temperature action and the length travel of big wind load composite condition control framework, so temperature action is very big for the influence of total.Therefore, often by the expansion joint form is set, disconnect the overlength framed bent in designing at present, solve the influence of temperature action; The structure floor space will enlarge, steel using amount increases but this design will make.
Summary of the invention
The objective of the invention is to overcome the deficiency of above-mentioned existence, can be out of shape by release temperature, eliminate the sliding support that be used for large-scale power transformation framework of temperature action the restriction of framework length and provide a kind of.It is joined with the slippage base plate of bottom and side direction respectively by vertical and two ball-types supports of level at least and forms, described ball-type is provided with a cover plate on supporting at least, and at least respectively has a side to link to each other with beam master material end plate with the framework post respectively on this cover plate and the described slippage base plate.
Described ball-type supports and comprises a graphite cake that links to each other with the slippage base plate, and this graphite cake joins with the spherical bearing that links to each other on the cover board by a sliding disc.
At least one side of described slippage base plate is provided with bolt hole, and is connected with the framework post with bolt; And at least one side of cover plate, equally also be provided with bolt hole, and be connected with beam master material end plate, they have constituted the main body link jointly.
The present invention reaches the restriction of elimination temperature action to framework length by designing a kind of sliding support, in three-dimensional cartesian coordinate system, this sliding support should be out of shape with release temperature in the flexible direction (being assumed to be the Y direction) of the temperature distance about 200mm of can sliding; Can transmit at other both directions (X and Z direction) again and transmit 10t respectively, the 20t left and right sides is stressed, to satisfy technological requirement.
The present invention can cancel intrinsic expansion joint, dwindles electric substation's floor space (with the 750kV power transformation example of doing, dwindle 3.6 mu of floor spaces, close 720,000 yuan of investments), saves the good farmland, reduces investment outlay.The present invention also can cancel a row framework, saves steel 100t, closes 1,000,000 yuan of construction investments.It has simple in structure, and is easy for installation, and sliding support has a style of one's own, and only needs just can continue to set up crossbeam after adding sliding support on the improved post gusset plate, does not change characteristics such as original mounting means substantially.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the A-A schematic diagram of Fig. 1.
Embodiment
The present invention will be described in detail below in conjunction with accompanying drawing: shown in the accompanying drawing 1,2, the present invention is joined with the slippage base plate 2 of bottom and side direction respectively by vertical and two ball-types supports 1 of level at least and is formed, described ball-type is provided with a cover plate 3 on supporting at least, and at least respectively has a side to link to each other with beam master material end plate 5 with framework post 4 respectively on this cover plate 3 and the described slippage base plate 2.
Ball-type shown in the figure supports 1 and comprises a graphite cake 11 that links to each other with slippage base plate 2, joins with spherical bearing 13 on being connected in cover plate 3 mutually by a sliding disc 12 on this graphite cake 11.
At least one side of slippage base plate 2 of the present invention is provided with bolt hole 32, and is connected with framework post 4 with bolt 32; And at least one side of cover plate 3, equally also be provided with bolt hole, and be connected with beam master material end plate 5 (not shown) with bolt, they have constituted the main body link jointly.
Specific embodiments of the invention are example with the 750kV framework:
One, through calculating 750kV framework three span length's degree 45 * 3=135m, temperature deformation (Y to) 61mm, according to technological requirement: beam-ends is vertically to (Z to) bearing load 6T, and level is to (X to) load 9T.
Two, according to the beam form of fracture of rectangle lattice, reach stressing conditions, designed beam end sliding support layout plan.At four main materials of lattice beam, one group of 4 sliding support is set respectively, four main materials all can be along beam axis direction (Y to) slip 100mm; Main material can transmit X, Z bidirectional stress down, goes up main material and only transmits X to stressed.
Three, according to sliding and force request design sliding support section and profile.Sliding support divides 3 parts: 1, ball-type support section, 2, slipper, 3, with the coupling part of main body.The ball-type support section comprises spherical bearing 13, the graphite cake 11 of sliding disc 12 and disk bottom is formed, because will guarantee enough spaces slides, generally 380mm is long at least for slippage base plate 21, parallel all the time for guaranteeing graphite cake 11 with slippage base plate 2, between cover plate 31 and sliding disc 12, establish spherical bearing 13.Comprise that the slippage base plate is connected with the framework column bolt, cover plate is connected with beam master material end plate bolt etc. two with the coupling part of main body.
Four, the sliding support of finishing according to design, original beam-column connection has been adjusted in the part, to satisfy the needs that add sliding support.
