Abstract
The utility model relates to a frame platform for installing an electric cable flexible arc. The frame platform is arranged on a flanged beam, and consists of channel steel or joist steel; the top of the frame platform has a horizontal structure and is provided with an electric cable support device; and the bottom of the frame platform is provided with a support base, and is erected on the flanged beam. Compared with the prior art, the frame platform is simple and smooth in a structure, and the horizontal structure on the upper part of the frame platform play the role of 'leveling' to ensure that the benchmark of the installation of a system is horizontal. Simultaneously, the frame platform provides connection for the installation of members on the upper part, and the bottom of the frame platform is erected on the flanged beam firmly and conveniently.
Description
Technical field
The utility model relates to a kind of sole plate, especially relates to a kind of pallet that is used to install the flexible arc of cable.
Background technology
For the bridge cabling, lay high-tension cable and need consider to adapt to this particular surroundings of bridge, avoid factor affecting cable running safeties such as bridge is flexible, vibration.When this engineering 220kV power cable lays in the place, expansion joint,, therefore need to be used for power cable laying and to absorb the flexible absorption plant that stroke changes, be called for short the offset device in the installation of the position at expansion joint in order to tackle the flexible amplitude of bridge better.
Bridge produces flexible and knuckle owing to be subjected to the influence of dynamic loading of current, the wind, earthquake etc. of variation of temperature, vehicle at the two ends of bridge.For soft junction structure length bridges such as suspension bridge, cable-stayed bridges, consider this two kinds of factors simultaneously; And for rigid structure small bridge such as metal bridge, concrete bridges, because knuckle changes not quite, can ignore, so only consider the telescopic variation of length direction.Since these variations have been arranged, just need take measures necessary to the cable on the bridge that is laid at the influence of stretching and knuckle causes, eliminate or the flexible adverse effect that variation causes cable with knuckle of reduction farthest.Modern bridge generally adopts concrete or steel construction, and bridge because variations in temperature, humidity variation and load variations all will cause bridge structure to deform, therefore need be installed the flexible arc system of cable on bridge in running.In the both sides of bridge, the stroke that absorbs cable by retractor device is an efficient ways.If the stroke of cable is not absorbed and compensates, produce when shrinking at bridge, because the extreme bending of cable causes bending, or produce when stretching at bridge, will produce excessive tension force to cable.The result that this state repeatedly takes place repeatedly, the worst situation is to cause cable breakage (insulation breakdown takes place before this).Because the flexible often out-of-flatness of arc system installation base surface of the inevitable property cable of error in the operations such as construction, installation, the sole plate pallet mainly be exactly the effect of playing one " levelling ", the datum-plane that the assurance system installs, the installation for upper component simultaneously provides connection.
The utility model content
The purpose of this utility model is exactly to provide the pallet that a kind of structure is smooth, the flexible arc of cable is installed in firm being used to of installation for the defective that overcomes above-mentioned prior art existence.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of pallet that is used to install the flexible arc of cable is characterized in that this pallet is located on the I-beam, be made of channel-section steel or i-steel component, the top of pallet is a horizontal structure, and the pallet top is provided with cable support device, the bottom of pallet is provided with supporting base, is erected on the I-beam.
Described cable support device is connected the top of pallet through bolt.
Described supporting housing is located on the I-beam of bridge body.
Compared with prior art, the utility model is simple in structure smooth, and top is horizontal structure, can play the effect of " levelling ", the datum-plane that the assurance system installs, the installation for upper component simultaneously provides connection, bottom shelf is located on the I-beam, and firm convenience is installed.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
1 is that pallet, 2 is that bolt, 3 is that supporting base, 4 is that cable support device, 5 is that cable, 6 is I-beam among the figure.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Embodiment
A kind of pallet that is used to install the flexible arc of cable, its structure as shown in Figure 1, this pallet 1 is located on the I-beam 6 of bridge body, pallet 1 is made of channel-section steel or the bigger member of I-steel uiform section rigidity, the top of pallet 1 is a horizontal structure, is provided with cable support device 4 at the top of pallet 1, is used for carrying cable 4, simultaneously support loads is delivered on the pallet 1, cable support device 4 is connected the top of pallet 1 through bolt 2.The bottom of pallet 1 is provided with supporting base 3, and pallet 1 is erected on the I-beam 6 of bridge body by supporting base 3.
Because the inevitable property of error in the operations such as construction, installation, the cable often out-of-flatness of arc system installation base surface of stretching, a main purpose of the present utility model plays the effect of " levelling " exactly, guarantee the datum-plane that the flexible arc system of cable installs, the installation for upper component simultaneously provides connection.
