Description

Technical Field

[0001] The utility model relates to the technical field of civil engineering, and particularly relates to a precast bridge member with uniform tensioning. Background Art

[0002] Precast bridge members are widely used in modern bridge construction. In order to ensure the quality and safety of bridges, it is necessary to tension the precast members to make them have sufficient strength and stiffness.

[0003] However, in the prior art, the tensioning of multiple groups of prestressed tendons in precast bridge members is not uniform. When the bridge is subjected to external tensile forces, the uneven tensioning will reduce the bearing capacity of the precast members and shorten the service life of the bridge. In addition, there is usually no buffer mechanism between traditional precast bridge members. Therefore, when the bridge shakes due to strong winds, the bridges will collide with each other, thereby damaging the bridge. Summary of the Utility Model

[0019] The buffer mechanism 2 includes a buffer pad 21, a connecting frame 23 is slidably connected to the inner wall of the buffer pad 21 through a through groove 22, and the through groove 22 is opened in the wall of the buffer pad 21, a honeycomb board 26 is fixedly connected to the inner wall of the connecting frame 23, and by passing the connecting frame 23 through the support column 38, all the support mechanisms 3 on the bridge body 1 are connected together, the outer wall of the buffer pad 21 is slidably connected to the inner wall of the bridge body 1, the inner wall of the bridge body 1 is in contact with the outer wall of the connecting frame 23, and the outer wall of the honeycomb board 26 is in contact with the inner wall of the bridge body 1.

[0020] The inner wall of the connecting frame 23 is fixedly connected to the outer wall of the support column 38 through a fixing groove 24, and the fixing groove 24 is opened in the wall of the connecting frame 23, a fixing block 25 is slidably connected to the outer wall of the connecting frame 23, and by sliding the fixing block 25 into the space between the connecting frame 23 and the buffer pad 21, the position of the connecting frame 23 is restricted, and the outer wall of the fixing block 25 is slidably connected to the inner wall of the buffer pad 21.

[0021] Working principle:

[0022] During use, before grafting the bridge body 1, the support mechanism 3 needs to be fixed in the bridge body 1. When preparing the bridge body 1, a circular groove 5 needs to be opened in the bridge body 1, and the support mechanism 3 is fixed in the circular groove 5. After the support mechanism 3 is fixed, the buffer mechanism 2 is slid into the installation groove 4 along the bridge body 1. The buffer mechanism 2 is used to create a movable space between the two bridge bodies 1, thereby preventing the bridge body 1 from being damaged due to external force torsion during use. At the same time, the support mechanisms 3 on the bridge body 1 are connected, so as to share the tensile force received by each support mechanism 3.

[0023] When preparing the bridge body 1, support rings 31 need to be linearly and arrayedly fixed in the circular groove 5, and then the connecting columns 32 are inserted along the circular groove 5. When installing the connecting columns 32, it should be noted that the small-diameter part of the cone in the connecting column 32 is inserted into the circular groove 5 first, so as to facilitate the installation of the connecting columns 32. After the connecting columns 32 are completely slid into the bridge body 1, the connecting columns 32 are restricted in position by the cones on the connecting columns 32 being stuck between the support rings 31. After the positions of the connecting columns 32 are fixed, the support ribs 34 are installed into the positioning frames 35 through the limit grooves 36 to ensure that the support ribs 34 are fixed in the positioning frames 35. Then, the positioning frames 35 are directly installed into the connecting columns 32 through the positioning grooves 33. After the positioning frames 35 are fixed in the connecting columns 32, the bridge body 1 is prepared. The connecting grooves 37 of the positioning frames 35 are fixed with support columns 38 by limit rings 39. Therefore, when the support mechanism 3 is installed into the bridge body 1, both ends of the support columns 38 need to extend out of the bridge body 1.

[0024] Then, when grafting the bridge body 1, the buffer mechanism 2 needs to be installed between the two bridge bodies 1. Just install the buffer pad 21 into the installation groove 4 first. After the position of the buffer pad 21 is fixed, then install the connecting frame 23 into the buffer pad 21 through the through groove 22. However, when installing the connecting frame 23, the fixing groove 24 on the connecting frame 23 needs to be aligned with the support column 38 in the support mechanism 3, so that the support column 38 passes through the connecting frame 23. And there is a fixing ring in the fixing groove 24. Therefore, when the support column 38 passes through the fixing groove 24, it is necessary to press the connecting frame 23 forcefully so that the support column 38 also passes through the fixing ring, thereby restricting the position of the support column 38.

[0025] Next, the fixed block 25 is slid into the buffer pad 21 along the through groove 22 on the buffer pad 21 to limit the position of the connecting frame 23. During the use of the bridge body 1, the tensile force generated by the outside world is transmitted to the connecting frame 23 along the support column 38, and then the tensile force is transmitted to the honeycomb panel 26 through the connecting frame 23, and then dispersed to all the support columns 38 on the connecting frame 23 through the honeycomb panel 26, so that each group of support columns 38 can be uniformly stressed. The force received by the support column 38 is transmitted to the positioning frame 35 along the support column 38, and then transmitted to the support ring 31 through the connecting column 32, so that the bridge body 1 can be uniformly stressed.

[0026] Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art and related fields without creative efforts shall fall within the scope of protection of the present invention.
