As preferably, the end of described support bar is fixed with cutting, and described crane span structure pipe is provided with slot, and described cutting is inserted slot and fixed.
As preferably, the two ends of described fastening strip are provided with longitudinally fixed bolt, and the corresponding longitudinally fixed bolt of described support bar is provided with vertical sliding elongated hole, and described longitudinally fixed bolt is fixing in vertical sliding elongated hole.
As preferably, being provided with vertical tightening bolt between neighbouring fastening strip.
As preferably, the both sides of described fastening strip be provided with cross section U-shaped tighten up groove, what the two ends of described vertical tightening bolt were each passed through neighbouring fastening strip tightens up groove.
This utility model adopts cable-stayed type cable testing bridge to cross over, and arranges pillar fixture on cable testing bridge cable protecting tube is fixed, it is ensured that pillar is fixing reliable, neat in crane span structure.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, this utility model is further described:
Fig. 1 is population structure schematic diagram of the present utility model.
Detailed description of the invention
A kind of cable protecting tube bridge structure, including the bridge pier being located in river and the cable testing bridge striding across river, described bridge pier is provided with arch-shaped steel frame, and described cable testing bridge is through arch-shaped steel frame, and described arch-shaped steel frame is fixed by oblique pull rope and cable testing bridge.
The advantage that employing cable-stayed type cable testing bridge is crossed over is: by being calculated analyzing to truss, arch drag-line, arch diagonal brace, 4 kinds of crane span structures of oblique pull; cable-stayed bridge cost is optimum; it addition, cable-stayed bridge two sides embedded depth of foundation is shallow, it is little to take up an area, the construction surface of two sides can be reduced; buried depth is more than the water surface; construction can evade river levee flood control protection problem largely, good with on-the-spot adaptability, and cable-stayed bridge is handsome in appearance; modern sense is strong, with environmental harmony.
As shown in Figure 1, cable testing bridge 2 is provided with the pillar fixture 1 that cable protecting tube 3 is fixed, described pillar fixture 1 includes some the fastening strips 11 be arrangeding in parallel up and down, described cable protecting tube 3 is fixed in side by side between neighbouring fastening strip 11, and described fastening strip 11 is provided with the circular arc locating slot 111 that cable protecting tube cylindrical is positioned.
Described cable testing bridge 2 includes the crane span structure pipe 21 being located at rectangle corner, is provided with support bar 22 in rectangle width both sides, and the two ends of described support bar 22 are fixed with crane span structure pipe 21.The end of described support bar is fixed with cutting 23, and described crane span structure pipe 21 is provided with slot, and described cutting 23 is inserted slot and realized fixing.
The two ends of described fastening strip 11 are provided with longitudinally fixed bolt 13, the corresponding longitudinally fixed bolt 13 of described support bar 22 is provided with vertical sliding elongated hole 221, described longitudinally fixed bolt 13 is fixing in vertical sliding elongated hole 221, and upper-lower position can be adjusted in vertical sliding elongated hole 221, to adapt to the cable protecting tube of different-diameter.This utility model adopts technique scheme, and cable protecting tube 3 rectangular array is fixed between Multilayer clamping bar, it can be ensured that cable protecting tube is fixing reliable, neat in cable testing bridge.
Vertical tightening bolt 12 it is provided with between neighbouring fastening strip 11.The both sides of described fastening strip 11 be provided with cross section U-shaped tighten up groove 112, what the two ends of described vertical tightening bolt 12 were each passed through neighbouring fastening strip tightens up groove 112, so neighbouring fastening strip is tightened up, thus cable protecting tube is fixed, it is to avoid cable protecting tube moves.
Additionally, the middle part of top side fastening strip is provided with the flange 113. that forward horizontal protrudes, the two ends of described flange are provided with stirrup 14, can fix cable protecting tube 3 by stirrup, and between this place's cable protecting tube and fastening strip, the cable effect of cable protecting tube diameter and carrying can be different.
