[0021] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.
[0022] Please refer to all the accompanying drawings below. It should be understood that the structures, proportions, sizes, etc., depicted in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of this invention. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of this invention, should still fall within the scope of the technical content disclosed in this invention. Furthermore, the terms such as "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and are not intended to limit the scope of this invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.
[0023] The following embodiments are for illustrative purposes only. These embodiments can be combined and are not limited to the content shown in any single embodiment below.
[0024] Please see Figures 1-2 This utility model provides a bridge cable saddle with high stability, comprising: an upper seat 1, a first fixed seat 2, a second fixed seat 3, a first connecting plate 4, a second connecting plate 5, multiple spaced connecting side plates 6, and multiple first anchor rods 7; the upper seat 1 is disposed on top of the first fixed seat 2; the multiple connecting side plates 6 are located between the first connecting plate 4 and the second connecting plate 5, and the connecting side plates 6, the first connecting plate 4, and the second connecting plate 5 are parallel and spaced apart; the tops of the first connecting plate 4, the second connecting plate 5, and the connecting side plates 6 are connected to the bottom of the first fixed seat 2, and the bottoms are connected to the top of the second fixed seat 3; one end of the multiple anchor rods is disposed on the first fixed seat 2, and the other end of the anchor rods is used to insert into the top of the bridge tower.
[0025] During construction, reinforcing bars can be placed in the gaps formed between the first connecting plate 4 and the adjacent connecting side plate 6, the gap formed between the second connecting plate 5 and the adjacent connecting side plate 6, and the gap formed between two adjacent connecting side plates 6. These reinforcing bars are then connected to the reinforcing cage of the bridge tower. Next, the first fixing seat 2, the second fixing seat 3, and the anchor rod are integrally cast into the bridge tower. During the casting process, the gaps formed between the first connecting plate 4 and the adjacent connecting side plate 6, the gap formed between the second connecting plate 5 and the adjacent connecting side plate 6, and the gap formed between two adjacent connecting side plates 6 are filled with concrete. Therefore, when uneven stress occurs at both ends of the main cable, because the cable saddle fixing seat is not only connected to the bridge tower via the anchor rod, but also because the first fixing seat 2, the second fixing seat 3, the connecting side plate 6, the first connecting plate 4, and the second connecting plate 5 are integrally cast into the bridge tower, the load on the main cable can be effectively transferred to the bridge tower, preventing relative displacement of the cable saddle relative to the bridge tower and thus avoiding any impact on the overall structural stability and safety.
[0026] Two sets of first support ribs 8 are also spaced apart at the bottom of the first fixed seat 2. Each set of first support ribs 8 may include multiple ribs, such as 4 or 5. One side of one set of first support ribs 8 is connected to the rear side wall of the first connecting plate 4, that is, the side wall of the first connecting plate 4 away from the connecting side plate 6; the other side of the first support ribs 8 is connected to the front side wall of the second connecting plate 5, that is, the side wall of the second connecting plate 5 away from the connecting side plate 6, to ensure the stability of the connection between the first fixed seat and the first connecting side plate 6 and the second connecting side plate 6. The bottom of each set of first support ribs 8 is also connected to the second fixed seat 3 to enhance the stability of the connection between the first fixed seat 2 and the second fixed seat 3. In addition, the arrangement of two sets of first support ribs 8 increases the contact area between the cable saddle and the retardant concrete, to ensure that the load on the main cable is effectively transferred to the bridge tower.
[0027] Please see Figures 1-3 The bridge cable saddle in this embodiment also includes multiple second anchor rods 9, one end of which is T-shaped. Multiple slotted holes 10 are spaced apart on the second fixing seat 3 for the T-shaped ends of the second anchor rods 9 to pass through. The slotted holes 10 are located between the first connecting plate 4 and the adjacent connecting side plate 6, the second connecting plate 5 and the adjacent connecting side plate 6, and between two adjacent connecting side plates 6. The top of the second fixing seat 3 is also provided with multiple first limiting members 11 for restricting the rotation of the T-shaped ends of the second anchor rods 9. The first limiting members 11 correspond one-to-one with the slotted holes 10.
[0028] Specifically, the second anchor rod 9 includes a shorter first metal piece and a longer second metal piece. One end of the first metal piece and the second metal piece are fixedly connected to form a second anchor rod 9 with one end in a T-shape. First limiting members 11 are spaced apart on two first limiting blocks in front of the waist-shaped hole 10 and on two second limiting blocks in rear of the waist-shaped hole 10. The gaps formed between the two first limiting blocks and the two second limiting blocks are used to accommodate the T-shaped end of the second anchor rod 9. In use, the first metal piece of the second anchor rod 9 is first passed through the waist-shaped hole 10, then the first metal piece is rotated, and one end of the first metal piece is placed into the gap between the two first limiting blocks, and the other end is placed into the gap between the two second limiting blocks. Thus, the first limiting members 11 can restrict the rotation of the second anchor rod 9.
[0029] The installation of the second anchor rod 9 increases the contact area between the cable saddle and the bridge tower. Simultaneously, the T-shaped end of the second anchor rod 9 abuts against the top of the second fixed seat 3, thus preventing the cable saddle from rotating towards the side where the main cable experiences uneven stress. Furthermore, the first limiting member 11 prevents the second anchor rod 9 from rotating during the pouring of the retarder, which could cause it to detach from the second fixed seat 3 through the waist-shaped hole 10.
[0030] The bridge cable saddle in this embodiment also includes a plurality of spaced connecting rods 12 and a plurality of fasteners 13, with at least one fastener 13 at each end of each connecting rod 12; an arc-shaped cable groove 14 is provided on the upper seat 1, and one end of the connecting rod 12 is detachably connected to the front side wall of the arc-shaped cable groove 14 through the fastener 13, and the other end is detachably connected to the rear side wall of the arc-shaped cable groove 14 through the fastener 13.
[0031] Specifically, the front and rear side walls of the arc-shaped cable groove 14 are provided with multiple mounting holes that correspond one-to-one with the connecting rod 12; the connecting rod 12 is a screw, the fixing member 13 is a nut, and the two ends of the connecting rod 12 pass through the mounting holes and are connected to the fixing member 13.
[0032] During construction, the screw can be removed from the upper seat 1 using the screw and nut, facilitating the installation of the main cable. After construction is completed, the screw is installed back onto the upper seat 1 to tension the two side walls of the arc-shaped cable groove 14, thereby increasing the load-bearing capacity of the cable saddle, preventing the main cable from slipping out of the arc-shaped cable groove 14, and avoiding damage to the two side walls of the arc-shaped cable groove 14.
[0033] The front and rear side walls of the upper seat 1 are each provided with a set of second support ribs 15; each set of second support ribs 15 may include multiple ribs, such as 4 or 5, and the bottom of each set of second support ribs 15 is connected to the top of the first fixed seat 2 to increase the load-bearing capacity of the cable saddle.
[0034] The top front and rear sides of the first fixed base 2 are respectively provided with first blocking members 16 for abutting against the corresponding second support ribs 15. Multiple third support ribs 17 are spaced apart on the side wall of each first blocking member 16 away from the second support ribs 15, and the bottom of the third support ribs 17 is connected to the top of the first fixed base 2. The top left and right sides of the first fixed base 2 are respectively provided with second blocking members 18 for abutting against the bottom side of the upper base 1.
[0035] Specifically, the upper seat 1 and the first fixed seat 2 can be connected by welding or other methods. The first blocking member 16 and the second blocking member 18 can be welded or integrally formed as blocking plates on the top of the first fixed seat 2. By setting the blocking plates, the upper seat 1 is limited before welding, and the load is also distributed during use.
[0036] In summary, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value.
[0037] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
