Detailed Description
The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings. It is to be understood that the description of the embodiments herein is for purposes of illustration and explanation only and is not intended to limit the invention.
In the present invention, the use of directional terms such as "upper, lower and outer" in the absence of a contrary indication generally means upper, lower and outer as shown in the accompanying drawings.
The utility model provides a two limbs tilting bridge tower, please refer to fig. 1 to 2 and show, including bridge tower body 1, girder 2 and cable 3, bridge tower body 1 includes pylon 4, two limbs pylon 5 and lower pylon 6, two limbs pylon 5 comprises two single limbs, two single limbs of two limbs pylon 5 are located respectively go up the both sides of pylon 4 and with it is fixed to go up the pylon 4, the bottom of two single limbs of two limbs pylon 5 is located respectively the both sides of pylon 6 down and with pylon 6 is fixed down, be provided with bridge floor 7 on the girder 2, the middle part of bridge floor 7 is provided with the median strip, it is located to go up the pylon 4 the bridge floor 7 top, the pylon 6 is located down the bridge floor 7 below, two limbs pylon 5 passes the bridge floor 7 just the cable 5 is fixed to be set up in the median strip, the setting of the slope of bridge tower body 1 is in and pass on the bridge floor 7 with the girder 2 is fixed.
