Problems solved by technology
[0003] However, with the development of railway construction, in order to meet various needs, the section width of the upper chord member of the railway steel truss suspension bridge is relatively large, and the section width of the upper chord member is even much larger than the diameter of the main cable clamp. At this time, the connecting ear plate of the anchor head of the straddle sling cannot directly use the integral gusset plate of the top chord, and it is necessary to develop a new type of steel anchor box suitable for the large section width of the top chord

Embodiment Construction
[0026] The present invention will be further described in detail below in conjunction with test examples and specific embodiments. However, it should not be understood that the scope of the above subject matter of the present invention is limited to the following embodiments, and all technologies realized based on the content of the present invention belong to the scope of the present invention.
[0027] Such as Figure 1-Figure 2 As shown, a steel anchor box suitable for straddling slings of railway steel truss suspension bridges includes a top plate 1, a bottom plate 2, two webs 3, two side plates 4 and two sets of lugs connected with the slings plate 5. Each set of lugs 5 includes a first lug 5a connected to the sling and two second lugs 5b for changing ropes, and several lug pin holes 7 and lugs are arranged on each first lug 5a. Plate reinforcement plate 6; each second ear plate 5b is provided with an ear plate pin hole 7 and an ear plate reinforcement plate 6. Each of...

The invention discloses a steel anchor box suitable for riding a span type cable of a railway steel truss girder suspension bridge, Include top panel, Bottom plate, two webs and two side plates, top plate, 2 web plate and 2 side plates compose a box structure, wherein the two side plates are parallel to the upper chord integral node plate lug plate, and the side plate is detachably connected withthe lug plate of the upper chord integral node plate, The box is structurally provided with two lug plates, the distance between the two lug plates is smaller than the distance between the lug platesof the two upper chord rod integral node plates, and the distance between the two lug plates is matched with the main cable clip; the lug plate is provided with a lug plate pin hole for connecting thesling; and the middle part of the top plate is provided with a mounting hole. The invention shortens the distance between the two lug plates so as to meet the installation requirements of the main cable clamp. The invention designs the steel anchor box as an independent structure, which is convenient for factory manufacture and field installation, and also convenient for later maintenance and replacement.
Description
technical field [0001] The invention relates to a steel anchor box, in particular to a steel anchor box suitable for straddling suspension cables of railway steel truss girder suspension bridges. Background technique [0002] The connection between the suspension bridge suspension cable and the main cable has a straddle type and a pin connection type. For straddle slings, the anchor heads at both ends need to be connected with stiffening beams. For road steel truss suspension bridges, the section width of the upper chord is generally smaller than the diameter of the main cable clamp. Therefore, the anchor heads at both ends of the straddle sling are mostly directly connected to the ear plates extending from the integral gusset plates on both sides of the upper chord. [0003] However, with the development of railway construction, in order to meet various needs, the section width of the upper chord member of the railway steel truss suspension bridge is relatively large, and ...
