The present utility model will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present utility model more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.
The welded type back cable anchor beam comprises a cross supporting plate 1, wherein an anchor plate 2 arranged along the left-right direction is arranged on the rear side of the cross supporting plate 1, and a first mounting groove 21 penetrating upwards is formed in the anchor plate 2; an outer vertical supporting plate 3 and a reinforcing rib plate 4 which are arranged along the front-back direction are arranged in front of the anchor plate 2, and the outer vertical supporting plate 3 is arranged on the left side and the right side of the transverse supporting plate 1; the reinforcing rib plates 4 are arranged between the outer vertical supporting plates 3.
Specifically, the steel plates can be integrally connected to each other by the cross-brace plates 1, and the whole body can be supported; the back cable can be anchored at the anchor beam through the first mounting groove 21 and the anchor plate 2; the whole stress of the anchor beam can be ensured through the outer vertical supporting plate 3 and the reinforcing rib plate 4. Wherein, the cross brace plate 1, the anchor plate 2, the first mounting groove 21, the outer vertical brace plate 3 and the reinforcing rib plate 4 are all connected by welding. According to the scheme, the steel plates are welded, the installation of the whole structure of the back cable anchor beam is realized, the welding process adopts fusion welding, the density of welded parts can be ensured to be relatively high, and the defects of air holes, inclusions, shrinkage cavities and the like are reduced. In addition, the change of heating and cooling temperatures in the welding process is small, and the defects such as cracks and the like caused by large stress in the part are reduced. In addition, the weld is typically produced in small volumes, and the ease of equipment and process control is added to provide better control over the occurrence of defects. Welded structures are also more flexible than cast structures and can accommodate different shapes and sizes, while cast parts require a certain number of molds to be made, which increases cost and time.
As another specific embodiment, a front pressure plate 5 disposed in the left-right direction is provided on the front side of the cross brace plate 1. Through setting up front pressure plate 5 for whole atress is box, and main welding seam and steel sheet all are in the pressurized state, more are favorable to the pressure-bearing capacity of performance material, and the structure atress is more excellent reliable. Specifically, the front pressing plate 5 is connected with the transverse supporting plate 1, the outer vertical supporting plate 3 and the reinforcing rib plate 4 through welding.
As another specific embodiment, the front platen 5 is provided with a second installation groove 51 penetrating upward. Since the back cable needs to be clamped into the first mounting groove 21 through the anchor beam, the blocking of the back cable can be prevented by the second mounting groove 51, so that the back cable can be stretched all the way to the first mounting groove 21 along the mounting direction. Specifically, the second mounting groove 51 and the first mounting groove 21 correspond in the front-rear direction.
As another specific embodiment, two sides of the front pressing plate 5 are provided with connecting plates 6. Since the anchor beam is finally required to be connected with the cable saddle body in a closing way, a connecting plate 6 is required to be arranged for connection.
As another specific embodiment, the front pressing plate 5 is higher than the anchor plate 2. It can be ensured that the stress of the anchor plate 2 is more reasonable.
As another specific embodiment, the upper end surface of the outer vertical supporting plate 3 and/or the reinforcing rib plate 4 is an inclined surface. Because the front pressing plate 5 is higher than the anchor plate 2, the anchor plate 2 and the front pressing plate 5 can be better connected through the outer vertical supporting plate 3 and/or the reinforcing rib plate 4 with the inclined upper end face, and the stress of the back cable anchor beam is balanced. In particular, the outer vertical support plate 3 and/or the reinforcing rib plate 4 is/are higher at the front pressing plate 5 and lower at the anchor plate 2.
As another specific embodiment, the reinforcing rib plate 4 is provided on the left and/or right side of the first mounting groove 21. Because the reinforcing rib plates 4 are used for increasing the stability of the hollow part in the middle of the anchor beam, so that the anchor beam has better compression resistance and tensile resistance, and the anchor beam is used for anchoring the back cable, the reinforcing rib plates 4 are arranged on the two sides of the first mounting groove 21, so that a better stable structure can be realized.
As another specific embodiment, the first mounting groove 21 is located above the cross plate 1. The back rope can be conveniently installed from top to bottom, and an installer can smoothly fasten the back rope to the bridge by utilizing the help of gravity.
As another specific embodiment, the lower end portion of the outer vertical support plate 3 protrudes below the cross support plate 1. Since the closer the cross plate 1 is to the theoretical line of the external load, the closer the first mounting groove 21 is. If the lower end surface of the outer vertical stay plate 3 is flush with the wale plate 1, a bending moment is generated, and the structure is disadvantageous.
As another specific embodiment, the rear end surface of the first mounting groove 21 is provided with a positioning groove. The anchor head of the cable strand can be quickly positioned during installation through the positioning groove, and the anchor head can be effectively prevented from being shifted.
