An adjustable anchor ear bracket of a cap beam of a single pier for bridge construction according to an embodiment of the present utility model is described below with reference to the accompanying drawings.
Referring to fig. 1 to 3, an adjustable anchor ear bracket of a cap beam of a single pier for bridge construction according to an embodiment of the present utility model includes an anchor ear 1, two beam bodies 2, four adjustable struts 3, and two supports 4. The anchor ear 1 can be fixed in on the pier stud, and it includes two halves staple bolt 5, and two halves staple bolt 5 all are half annular overall, and the both ends of two halves staple bolt 5 all outwards buckle to form the engaging lug, can be fixed in on the pier stud with two halves staple bolt 5 through the bolt.
The two beam bodies 2 are arranged above the anchor ear 1 and are used for jointly supporting the cast-in-situ capping beam construction platform. The beam body 2 may be i-steel, and two beam bodies 2 are horizontally arranged.
The four adjustable supporting rods 3 are obliquely arranged, the lower ends of the adjustable supporting rods are rotatably connected with the anchor ear 1, and the upper ends of the adjustable supporting rods are rotatably connected with the corresponding beam bodies 2. The adjustable support rods 3 support the same beam body 2 together, and the inclination angle of the beam body 2 can be adjusted by adjusting the length of the adjustable support rods 3. The capping beams with different gradients do not need to be refitted, the length of the supporting rod 9 can be directly adjusted to change the gradient of the construction platform, and the capping beam is convenient to use. In order to further improve the stability of the beam body 2, the adjustable hoop support may further include two pairs of tie rods 6, where the two pairs of tie rods 6 are arranged perpendicular to the beam body 2, and two ends of each pair of tie rods 6 are fixedly connected with the two beam bodies 2. The two pairs of pull rods 6 can be finish-rolled thread pairs of pull rods, the beam body 2 is provided with a through hole for the ends of the pairs of pull rods to extend out, and the two ends of the pairs of pull rods 6 are locked by using gaskets and nuts.
