Abstract
The utility model relates to a support device used in a cable expansion arc, which comprises a cable backstop, a bracket cross arm and an upright column, wherein the cable backstop is arranged under cables of the cable expansion arc, and the cables are laid at the top; the bracket cross arm is arranged at the lower part of the cable backstop; and the upright column is connected with the lower part of the bracket cross arm. Compared with the prior art, the support device has the advantages of simple structure and convenience for use, the expansion cable arc can be well fixed and installed on a bridge, the support of the support device is firm, and unfavorable influences on the cables by expansion and fold angle changes are reduced to a maximal extent.
Description
Technical field
The utility model relates to a kind of support device, especially relates to a kind of support device that uses in the flexible arc of cable.
Background technique
Along with the development of regional economy and the refinement of zone location, domestic development and use to offshore island day by day heat up, pay attention to further in recent years.A plurality of islands, the whole nation have been warded off is shipbuilding base, generating base, combustion gas terminal, port and pier etc., wherein is no lack of the Changxing Island in Shanghai shipbuilding base is arranged, island harbour mouth base, mountain, small ocean etc.Establish and solve long-term goods and materials transportation problem for what cooperate these bases, local government is also often glad to build bridge to connect all islands and continent.This just provides a kind of new way for solving the long-term electric power transportation problem of scratching the island that is stranded.
Bridge produces flexible and knuckle owing to be subjected to the influence of dynamic load 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 structure, and bridge because temperature variation, 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.
But, 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 model utility content
The purpose of this utility model is exactly that a kind of firm supporting, the support device that uses in the flexible arc of cable simple in structure, easy to use are provided in order to overcome the defective that above-mentioned prior art exists.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of support device that in the flexible arc of cable, uses, it is characterized in that, this support device comprises cable bracket, support cross-arm and column, described cable bracket is located under the cable of the flexible arc of cable, the top is laid with cable, described support cross-arm is located at the bottom of cable bracket, and described column is connected the bottom of support cross-arm.
Described cable bracket is the typing anchor clamps of attached cable.
Described support cross-arm is located between cable bracket and the column, adopts square steel, angle steel or steel pipe to make.
Described column is a bending component, and the top is connected with the support cross-arm, and the bottom is located on the sole plate, adopts I-steel, square steel, steel pipe or channel-section steel member to make.
Described cable bracket by the support cross-arm with Load Transfer on column and sole plate.
Compared with prior art, the utility model is simple in structure, and is easy to use, can be good at the retractable cable arc is fixedly mounted on the bridge, and firm supporting, farthest reduce adverse effect flexible and that the knuckle variation causes cable.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
1 is that cable bracket, 2 is that support cross-arm, 3 is that column, 4 is that cable, 5 is sole plate among the figure.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Embodiment
A kind of support device that in the flexible arc of cable, uses, its structure as shown in Figure 1, this support device comprises cable bracket 1, support cross-arm 2 and column 3, cable bracket 1 is the typing anchor clamps of attached cable, be located under the cable of the flexible arc of cable, the top is laid with cable 4, support cross-arm 2 is located between cable bracket 1 and the column 3, adopt to connect easy and have the square steel of certain rigidity of section, member such as angle steel or steel pipe is made, column 3 is a bending component, the top is connected with support cross-arm 2, and the bottom is located on the sole plate 5, chooses the I-steel that rigidity of section is big and be convenient to connect, square steel, member such as steel pipe or channel-section steel 5 is made.Cable bracket 1 by support cross-arm 2 with Load Transfer on column 3 and sole plate 5.
