[0014] The utility model is further configured as follows: the embedded sleeve is arranged in a common clamping area of ​​two short rods and two long rods.

[0015] By adopting the above technical solution, the embedded sleeve is positioned by the joint action of two short rods and two long rods, so that the embedded sleeve will not be offset during the casting process of the template.

[0016] The utility model is further configured as follows: the outer wall of the template body is coated with epoxy resin.

[0017] By adopting the above technical solution, a protective surface coating is formed on the outer wall of the template body. These coatings not only provide mechanical protection, but also form a barrier to prevent erosion by air, moisture and chemicals.

[0018] The utility model provides a rapid installation template for the pad stone of a rail transit elevated bridge.

[0019] Beneficial effects:

[0020] (1) The utility model slides a short rod from the end of the second slide groove onto the long guide block, and then slides the corresponding long rod from the end of the first slide groove onto the short guide block. Then, according to the construction drawing, the scale bar is compared, and multiple short rods and long rods are slid to the corresponding positions. Then, the embedded sleeve is placed in the area where the short rods and long rods are clamped together. Finally, the short rods and long rods are locked by bolts, thereby achieving the effect of precise positioning.

[0021] (2) The utility model makes it easy to disassemble and install the template body by cooperating with the convex block on the wide template and the convex groove on the long template, which greatly improves work efficiency. The outer wall of the template body is coated with epoxy resin, so that a protective surface coating is formed on the outer wall of the template body. These coatings not only provide mechanical protection, but also form a barrier to prevent erosion by air, moisture and chemicals. BRIEF DESCRIPTION OF THE DRAWINGS

The two short guide blocks 21 are opposite to each other and are respectively provided with a slide groove 23 and a through hole 24. The two short guide blocks 21 are slidably connected to two short rods 27 through the slide groove 23. The height of the short guide block 21 is higher than the height of the long guide block 22, which is convenient for the long rod 28 to slide into the short guide block 21 from the end of the slide groove 23 and the short rod 27 to slide into the long guide block 22 from the end of the slide groove 25. The embedded sleeve 3 can also be kept vertically downward. The two long guide blocks 22 are opposite to each other and are respectively provided with a slide groove 25 and a through hole 26. The long guide block 22 is slidably connected to two long rods 28 through the slide groove 25. The short rod 2 7. Bolts 29 are threadedly connected at both ends of the long rod 28, and the bolts 29 at both ends of the short rod 27 pass through the second through hole 26, and the bolts at both ends of the long rod 28 pass through the first through hole 24. The short rod 27 and the long rod 28 are fixed by the bolts 29 to prevent the short rod 27 and the long rod 28 from moving during the pouring process, thereby affecting the positioning accuracy. The embedded sleeve 3 is arranged in the common clamping area of ​​the two short rods 27 and the two long rods 28. The embedded sleeve 3 is positioned by the joint action of the two short rods 27 and the two long rods 28, so that the embedded sleeve 3 will not be offset during the pouring process of the template. The tops of the short guide block 21 and the long guide block 22 are engraved with scale bars 210;

[0031] The template body 1 is surrounded by a wide template 1003 and a long template 1001.
