Description

Technical Field

[0001] The utility model relates to the technical field of bridge construction equipment, in particular to a core rod fixing device used in bridge construction. Background Art

[0002] In bridge support construction, the through-rod method is a type of non-ground support. Due to its practicality and high safety, the through-rod method is widely used in the construction of cylindrical piers and rectangular pier cap beams. During bridge construction, through-rod installation holes are reserved at the predetermined locations of the piers. After the piers are cast, the through-rods are installed through these holes to form a stable support structure. Currently, the through-rods are typically fixed using steel sleeves or cutouts in channel steel. However, due to the inability to accurately determine the position of the through-rods, the cutouts in the channel steel are often relatively large, making it impossible to prevent the through-rods from rotating.

[0016] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0017] like Figure 1 As shown, an embodiment of the utility model proposes a through-rod fixing device for bridge construction, comprising: a fixing seat 1, a clamping seat 2 and a connecting assembly, wherein there are two clamping seats 2, both of which are arc-shaped, and the two clamping seats 2 are arranged opposite to each other, and the connecting assembly is arranged between the fixing seat 1 and one of the clamping seats 2, and both ends of the two clamping seats 2 are provided with extension parts 3, and the two mutually symmetrical extension parts 3 of the two clamping seats 2 are locked by a locking assembly, the fixing seat 1 is used to be connected to the bridge structure, and the length of the connecting assembly is adjustable.

[0018] By designing the two clamping seats 2 into an arc shape, the two clamping seats 2 can fit more closely on the through-rod 4, and then the locking assembly locks the extension 3 at the end of the two clamping seats 2, so that the two clamping seats 2 clamp the through-rod 4, thereby fixing the through-rod 4 and preventing the through-rod 4 from rotating; at the same time, by providing a length-adjustable connecting assembly, it is convenient to adjust the distance between the clamping seat 2 and the bridge structure, thereby facilitating the fixing seat 1 to be fixed on the bridge structure.

[0019] Further, such as Figure 1 As shown, the connecting assembly includes: at least one connecting column 5 fixedly arranged at the bottom of the fixing seat 1, the bottom of each connecting column 5 is recessed to form a slide groove, one end of a sliding column 6 is slidably arranged in each slide groove, and the other end of each sliding column 6 is fixedly connected to the top of one of the clamping seats 2, and the sliding column 6 and the connecting column 5 are locked by bolts 7.

[0020] like Figure 1 As shown, as a first embodiment, the locking assembly includes: a mounting block 8 and a screw 10. The mounting block 8 is provided with a channel 9 for the extension 3 at the end of the clamping seat 2 to pass through. The two extensions 3 at the opposite ends of the two clamping seats 2 are both inserted into the channel 9. The screw 10 is vertically inserted into the channel 9 from the top of the mounting block 8. The end of the screw 10 is pressed against the top of the extension 3. The screw 10 is threadedly connected to the mounting block 8. Specifically, when locking the two clamping seats 2, first insert the two extensions 3 at the same end of the two clamping seats 2 into the channel 9 of the mounting block 8, and then rotate the screw 10 so that the screw 10 moves vertically downward and presses against the top of the extension 3, while the other extension 3 is in close contact with the bottom of the channel 9, thereby achieving the goal of clamping the two extensions 3 in the channel 9.

[0021] like Figure 2 As shown in the second embodiment, the locking assembly includes a bolt 7 , and the two extensions 3 are locked by the bolt 7 .

[0022] Specifically, it also includes: a clamping tile seat 11, and the clamping tile seat 11 can be detachably provided on the opposite sides of the two clamping seats 2, and the clamping tile seat 11 is also arc-shaped. The inner surface of each clamping seat 2 is provided with a sliding groove, and the side wall of the corresponding clamping tile seat 11 is provided with a sliding block 12, and the sliding block 12 is slidably connected to the sliding groove. The side wall of each sliding groove is provided with a guide groove, and the side wall of the sliding block 12 is provided with a guide block 13 slidably connected to the guide groove. Through the design of the clamping tile seat 11, clamping tiles 11 with different inner diameters can be replaced, so that the inner diameter of the clamping tile seat 11 matches the diameter of the through-rod 4, that is, the clamping tile seat 11 can fit on the surface of the through-rod 4, thereby improving the clamping effect.
