DETAILED DESCRIPTION

[0023] The utility model embodiment is explained in detail below in combination with the drawings.

[0024] As Figs. 1-2 The utility model discloses a prefabricated T beam template cross slope adjusting device, including upper channel steel 1, lower channel steel 2, vertical channel steel 3, jacking mechanism 4 and reinforcing bar frame 5, the jacking mechanism 4 includes jacking piece 41, the bottom of jacking piece 41 is fixed on lower channel steel 2, the top of jacking piece 41 abuts on upper channel steel 1 and can realize the jacking of upper channel steel 1, one end of lower channel steel 2 is fixed on the side of vertical channel steel 3, and the side, away from lower channel steel 2, of upper channel steel 1 and vertical channel steel 3 is provided with reinforcing bar frame 5.

[0025] Jacking mechanism 4 is at least 2, and one jacking mechanism 4 corresponds to one upper channel steel 1, lower channel steel 2 and vertical channel steel 3, and the jacking mechanism 4 is connected with electric hydraulic pump 6 through pipeline, the opening of electric hydraulic pump 6 can realize the simultaneous jacking of several jacking mechanisms 4, and further make the corresponding upper channel steel 1 change position.

[0026] In the utility model, jacking piece 41 is preferably hydraulic jack, and of course jacking piece 41 can also be cylinder and other components that can realize jacking action;Jacking piece 41 includes cylinder body fixed on lower channel steel 2 and jacking rod that can act along the vertical direction of cylinder body.

[0027] Specifically, upper channel steel 1 is cut off between vertical channel steel 3, lower channel steel 2 is connected with vertical channel steel 3, the cylinder body of jacking piece 41 is fixed on lower channel steel 2, and the top of jacking rod of jacking piece 41 abuts on upper channel steel 1 and can realize the jacking of upper channel steel 1;Upper channel steel 1 changes position under the jacking of jacking piece 41, and cross slope value=(center point elevation - sideline point elevation) / (center point to sideline point distance) × 100%, thus, the position change of upper channel steel 1 and vertical channel steel 3 changes bridge deck cross slope value, and finally, the setting of bridge deck cross slope is determined.

[0028] In order to realize the jacking of jacking mechanism 4 to upper channel steel 1 better, and further realize the setting of bridge deck cross slope.

[0029] The jacking mechanism 4 comprises a connecting block 42 sleeved on the top of the jacking piece 41, and the upper surface of the connecting block 42 is flush with the top surface of the jacking piece 41.

[0030] The connecting block 42 comprises a circular hole 424, a first slot 421 and a second slot 422 which are arranged at intervals along the circumference of the connecting block 42, and the first slot 421 and the second slot 422 both extend from the outside of the connecting block 42 to the inside of the connecting block 42. The connecting block 42 is sleeved on the jacking rod through the circular hole 424.

[0031] The width of the first slot 421 is smaller than the width of the second slot 422, and a threaded hole 423 which penetrates the circular hole 424 is arranged in the second slot 422. The bolt passes through the second slot 422 and the threaded hole 423 to fix the connecting block 42 on the jacking piece 41. In order to ensure the higher connection strength of the connecting block 42 on the jacking piece 41, of course, a through hole corresponding to the threaded hole 423 can also be drilled on the jacking rod, and the bolt passes through the second slot 422, the threaded hole 423 and the circular hole of the jacking rod to fix the connecting block 42 on the jacking piece 41.

[0032] The jacking mechanism 4 comprises a limiting block 43, and one limiting block 43 is arranged on each side of the connecting block 42. The limiting block 43 is used for limiting the upper channel steel 1.

[0033] The limiting block 43 comprises a limiting threaded hole 431 which corresponds to the first slot 421. The bolt passes through the first slot 421 and the limiting threaded hole 431 and is locked by a nut to fix the limiting block 43 and the connecting block 42.

[0034] Specifically, the connecting block 42 increases the contact area of the jacking mechanism 4 and the upper channel steel 1 on the one hand, which helps the jacking mechanism 4 to stably jack the upper channel steel 1. On the other hand, the limiting block 43 is fixed on the jacking piece 41, which facilitates the limiting block 43 to limit and position the upper channel steel 1 and avoids the horizontal movement of the upper channel steel 1.

[0035] Further, since the upper channel steel 1 is not always jacked by the jacking mechanism 4 at the center position, in order to ensure the stability of the jacking of the upper channel steel 1, the limiting block 43 can be welded at the contact position with the upper channel steel 1. After the setting of the bridge deck transverse slope is completed, the bolt between the limiting block 43 and the connecting block 42 is removed, so that the jacking piece 41 and the limiting block 43 can be quickly removed, which facilitates the use of the jacking piece 41 next time.

[0036] The upper channel steel 1 comprises a first channel steel section 11 and a second channel steel section 12 which are arranged at an angle and are welded and connected. A gap is left between the second channel steel section 12 and the vertical channel steel 3.

[0037] The steel bar frame 5 comprises a support frame 51 arranged on the upper channel steel 1 and the vertical channel steel 3, and a panel 52 covering the support frame 51.

[0038] Specifically, the second channel steel section 12 realizes the transition between the first channel steel section 11 and the vertical channel steel 3, reduces the difficulty of subsequent installation of the steel bar frame 5, and makes the bridge deck transverse slope transition more natural.

[0039] The support frame 51 arranged on the upper channel steel 1 and the vertical channel steel 3 increases the strength of the bridge deck transverse slope, and the panel 52 arranged on the support frame 51 makes the bridge deck transverse slope convenient for pedestrians to travel, and if there is a misalignment between the horizontal panel and the vertical panel constituting the panel 52, the misalignment is polished and then leveled by adhesive.

[0041] Step 1: according to the drawings, the size of the upper channel steel 1, the lower channel steel 2, the vertical channel steel 3 and the steel bar frame 5 is determined, and then the height that the jacking mechanism 4 needs to adjust is calculated according to the set transverse slope value;
