Abstract
Description
Technical Field
[0001] The utility model relates to the field of municipal engineering, and more specifically, it relates to a bridge structure. Background Art
[0002] A bridge is a structure erected over rivers, lakes and seas to enable vehicles, pedestrians, etc. to pass smoothly. To adapt to the modern rapidly developing transportation industry, a bridge is also extended to a building that is erected across mountain streams, poor geological conditions or to meet other traffic needs to make passage more convenient.
[0003] Bridges are generally divided into pier columns, capping beams and box girders. Among them, the capping beam is located at the top of the pier column, and both ends of the box girder are erected on the capping beam. To ensure the construction speed, the box girder is prefabricated in the factory and then transported to the construction site for assembly. To facilitate the transportation of the box girder, the number of box girders between two capping beams is multiple. And after the box girders between two capping beams are erected, people need to pour and connect several box girders together. Currently, it is mostly connected by concrete pouring. Therefore, several steel bars generally protrude from both sides of the box girder to ensure the strength of the pouring connection.
[0004] Before the pouring connection, people need to set a pouring plate between two capping beams. Both sides of the pouring plate are respectively in contact with the lower bottom surfaces of the two capping beams. The pouring plate is used to support the weight of the concrete. Therefore, the strength required for the connection between the pouring plate and the two capping beams is relatively high. Currently, the pouring plate is generally fixed on the box girder by bolts, and the number of bolts on both sides of the pouring plate is relatively large, which can ensure the degree of fit between both sides of the pouring plate and the box girder. After people fit the pouring plate to the bottom surface of the box girder, the bolts pass through the pouring plate from bottom to top and are fixed on the box girder. However, due to the large number of bolts, the time required for people to tighten the bolts is relatively long. During the process of tightening the bolts, since people are located between two box girders, the activity range of people is small and people's movement depends on the movement of the working platform, resulting in insufficient freedom of movement and inconvenience for people to operate.
[0005] Therefore, a new solution needs to be proposed to solve this problem. Summary of the Utility Model

In the process of rotating the bolts, the casting plate 5 is limited by the limiting parts, so that the casting plate 5 will not rotate. After all the bolts are tightened, both sides of the casting plate 5 are tightly attached to the lower side of the partition bar 3. Because the time required for pre-fixing the casting plate 5 is short, while the time required for tightening several bolts is long, people only need to use the mobile working platform in the process of pre-fixing the casting plate 5. In the process of tightening the bolts, people operate on the box beam. The range of activities on the box beam is large and people are more free to move without relying on the working platform. Therefore, it is convenient for people to install the casting plate 5.
[0022] like Figure 2 and Figure 3 As shown, a waist-shaped hole 8 is provided on the diaphragm 4 and runs through the thickness direction thereof, a sliding groove 9 is provided on the side wall of the casting plate 5, and the limiting member is an embedded rod 10 slidably connected in the sliding groove 9, one end of the embedded rod 10 can slide out of the sliding groove 9 and be embedded in the waist-shaped hole 8, people insert the embedded rod 10 into the waist-shaped hole 8 by sliding the embedded rod 10 in the casting plate 5, and the casting plate 5 is ensured not to fall by the cooperation of the embedded rod 10 and the waist-shaped hole 8, the width of the waist-shaped hole 8 is equal to the diameter of the embedded rod 10, the number of embedded rods 10 in the casting plate 5 is four, and the four embedded rods 10 are respectively arranged near the four corners of the casting plate 5, two of which are extended from the front side of the casting plate 5, and the other two are extended from the rear side of the casting plate 5, when the four embedded rods 10 are all embedded in the waist-shaped hole 8, the threaded hole 7 is aligned with the through hole 6, and the width of the waist-shaped hole 8 is equal to the diameter of the embedded rod 10, so that the embedded rod After 10 is embedded in the waist-shaped hole 8, the casting plate 5 is not easy to move in the horizontal direction, thereby ensuring the alignment of the through hole 6 and the threaded hole 7. The number of embedded rods 10 is four, thereby ensuring the stability of the pre-fixation of the casting plate 5. The length of the waist-shaped hole 8 is greater than the diameter of the embedded rod 10, and the upper end of the waist-shaped hole 8 is arranged close to the lower side of the inlay. This arrangement makes it easy for people to control the embedded rod 10 during the tightening of the bolts, until the two sides of the casting plate 5 are tightly attached to the lower side of the inlay, ensuring the installation effect of the casting plate 5. A toggle groove 11 connected to the sliding groove 9 is provided on the side of the casting plate 5 facing away from the partition bar 3, and a toggle rod 12 at one end connected to the embedded rod 10 is provided in the toggle groove 11. People control the sliding of the embedded rod 10 by sliding the toggle rod 12 in the toggle groove 11.
