Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please see Figures 1 to 4 , Figure 1 A schematic diagram of a preferred embodiment of the adjustable bridge shield mold provided by this utility model; Figure 2 for Figure 1 The top view of the first and second template structures shown; Figure 3 for Figure 2 The diagram shows an enlarged view of the structure at point A. Figure 4 for Figure 1 The diagram shows a side view of the internal structure of the support plate. The adjustable bridge shield mold provided by this utility model includes a bottom mold 7, with support plates 3 symmetrically installed on both sides of the bottom mold 7. A limiting plate 31 is symmetrically fixedly connected to the bottom end of each support plate 3, and the limiting plate 31 is fixed to the surface of the bottom mold 7 by bolts. A screw 9 is slidably connected to the side wall of the support plate 3, and a second template 4 is provided at one end of the screw 9. A first template 2 is symmetrically placed on the surface of the bottom mold 7. The side wall of the support plate 3 is slidably connected to an adjusting rod 12, and the adjusting rod 12 is threadedly connected to a fixing column 14. A clamping plate 15 is fixedly connected to one end of the fixing column 14. Multiple first ribs 5 are fixedly connected to the surface of the first template 2, and the side walls of the first ribs 5 engage with the clamping plate 15. During the installation of the first template 2 and the second template 4, the second template 4 is first installed between the two support plates 3. The second template 4 is connected to the support plate 3 using the screw 9, thereby fixing the second template 4 with the support plate 3 as a support. The first template 2 is installed on the bottom mold 7. The adjusting rod 12 is threaded through the support plate 3 and the fixing column 14. The fixing column 14 is located outside the first template 2, so that the fixing column 14 and the support plate 3 protect the first template 2 and prevent the first template 2 from tilting outward.

[0022] The first template 2, the second template 4, and the bottom mold 7 are combined to form a mold for casting the shielding plate 1. A rubber strip 16 is engaged at the edge of the side wall of the second template 4, and the rubber strip 16 abuts against the side wall of the first template 2. In order to increase the sealing of the connection between the first template 2 and the second template 4 and prevent grout leakage, the rubber strip 16 is used.

[0023] The second rib 6 is fixedly connected to the center of the side wall of the second template 4. The side wall cross-sections of the second rib 6 and the first rib 5 are in the shape of a "T" and the first rib 5 and the second rib 6 are perpendicular to each other. The ribs are used to increase the stability and firmness of the first template 2 and the second template 4.

[0024] Multiple clamping plates 8 are slidably connected to the side wall of the second rib plate 6. The interior of the clamping plates 8 is slidably connected to the screw 9. The side wall of the support plate 3 is symmetrically provided with first sliding grooves 11. The screw 9 is slidably connected to the interior of the first sliding grooves 11. The side wall of the screw 9 is threadedly connected to the fixing cylinder 10. The fixing cylinder 10 abuts against the surface of the support plate 3, and the diameter of the fixing cylinder 10 is larger than the width of the first sliding groove 11. In order to facilitate the sliding connection of the clamping plates 8 to the side wall of the second rib plate 6 and align the clamping plates 8 with the first sliding groove 11, the screw 9 is threaded through the first sliding groove 11 and connected to the clamping plates 8. Then, the fixing cylinder 10 is rotated on the side wall of the screw 9 so that the fixing cylinder 10 abuts against the side wall of the support plate 3. Thus, by rotating the fixing cylinder 10, the screw 9 and the second template 4 are moved, and the position of the second template 4 is adjusted.

[0025] The support plate 3 has symmetrical second sliding grooves 13 on its sidewalls. The adjustment rod 12 with a "T"-shaped sidewall is slidably connected inside the second sliding groove 13. The maximum diameter of the adjustment rod 12 and the width of the fixing column 14 are both greater than the width of the second sliding groove 13. In order to allow the adjustment rod 12 to pass through the second sliding groove 13 and enter the interior of the fixing column 14, the fixing column 14 moves toward the position of the support plate 3, so that the fixing column 14 drives the clamping plate 15 to press the first rib 5 and fix the first template 2.

[0026] The side wall of the fixed column 14 is threadedly connected to the limiting rod 17, and the limiting rod 17 abuts against the side wall of the first template 2. In order to facilitate the rotation of the limiting rod 17, the limiting rod 17 squeezes the first template 2, thereby increasing the sealing at the connection between the first template 2 and the second template 4.

[0027] The adjustable bridge shield mold provided by this utility model operates on the following principle: Based on the width of the shield 1, a suitable second template 4 is selected. The length of the second template 4 is less than the length of the support plate 3, the length of the shield 1 is less than the length of the first template 1, and the length of the first template 1 is less than the distance between the two support plates 3, thus facilitating the adjustment of the first template 2 and the second template 4. The second template 4 is placed between the two support plates 3. At this time, the clamping plate 8 is slidably connected to the side wall of the second rib 6, aligning the clamping plate 8 with the first sliding groove 11. The screw 9 is threaded through the first sliding groove 11 and connected to the clamping plate 8. Then, the fixing cylinder 10 is rotated on the side wall of the screw 9, thereby initially fixing the second template 4. The first template 2 is placed on the bottom mold 7. The adjusting rod 12 is inserted through the second sliding groove 13 into the interior of the fixing column 14, causing the fixing column 14 to move towards the position of the support plate 3, fixing the fixing column 14 to the side wall of the support plate 3. The fixing column 14 and the second template 4 prevent the first template 1 from tipping over. Adjust the positions of the first template 2 and the second template 4 according to the length of the cover plate 1. After the first template 2 and the second template 4 are assembled, rotate the adjusting rod 12 into the interior of the fixing column 14, so that the fixing column 14 drives the clamping plate 15 to hook and press the first rib plate 5, thus fixing the first template 2. Rotate the fixing cylinder 10 to press the side wall of the support plate 3, thus fixing the second template 4. Rotate the limiting rod 17 on the side wall of the fixing column 14, so that the limiting rod 17 presses the first template 2, increasing the sealing at the connection between the first template 2 and the second template 4. After the templates are assembled, a reinforcing cage is overlapped inside the templates, and then concrete is poured to form the cover plate 1.
