[0039] Example 2

[0040] According to some embodiments of the present application, the bottom ends of the first side formwork 4 and the second side formwork 12 are respectively provided with a first base plate 2, and the top end of the first base plate 2 is welded and fixed with a first slide rail 3, the bottom ends of the first side formwork 4 and the second side formwork 12 are respectively provided with slide grooves 13, and the two ends of the slide groove 13 in the length direction respectively penetrate the two ends of the first side formwork 4 and the second side formwork 12, the first side formwork 4 and the second side formwork 12 are respectively slidably connected to the first slide rail 3 through the slide grooves 13, the rear end of the first slide rail 3 is provided with a second slide rail 20, and the bottom end of the second slide rail 20 is welded and fixed with a second base plate 21, the rear ends of the tops of the first slide rail 3 and the second slide rail 20 are respectively provided with slots 17, and the front end of the second slide rail 20 is welded and fixed with an insert 18.

[0041] A first reserved hole 19 is provided inside the top of the plug block 18, and a connecting bolt 25 is provided inside the first reserved hole 19. A threaded hole 22 is provided at the bottom end of the slot 17, and the bottom end of the connecting bolt 25 penetrates the inside of the plug block 18, thereby fixing the plug block 18 in the slot 17. Second reserved holes 24 are provided at both ends of the top of the first slide rail 3, and a fixing bolt 23 is provided inside the second reserved hole 24. The bottom end of the fixing bolt 23 penetrates the inner holes of the first slide rail 3 and the first bottom plate 2 in turn, and is fixedly connected to the embedded parts on the bridge deck 1.

[0042] Specifically, Figure 1 , Figure 3 and Figure 4 As shown, when installing the sliding formwork device, two groups of holes can be opened at the top of the bridge deck 1, and embedded pipes can be buried in the holes. Then, two groups of fixing bolts 23 are used to penetrate the first slide rail 3 and the first bottom plate 2 from the second reserved holes 24 and screwed into the embedded pipes inside the bridge deck 1, so that the first bottom plate 2 and the first slide rail 3 can be fixedly installed at the top of the bridge deck 1. Then, when installing the second slide rail 20 and the second bottom plate 21 at the rear end of the first slide rail 3, the plug block 18 fixed at the front end of the second slide rail 20 is first inserted downward into the slot 17 inside the rear end of the first slide rail 3, and then the connecting bolts 25 are used to penetrate the plug block 18 from the first reserved holes 19 and screwed into the threaded holes 22, so that the second slide rail 20 and the second bottom plate 21 can be installed and fixed at the rear end of the first slide rail 3.

The second slide rail 20 and the second base plate 21 can be provided in multiple groups. During installation, only holes need to be drilled to install the first base plate 2 and the first slide rail 3. No holes need to be drilled during the subsequent extended installation, which makes it easy to extend the template according to the length of the anti-collision guardrail on the bridge.

[0043] Example 3

[0044] According to some embodiments of the present application, a bidirectional lead screw 8 is laterally movably connected inside the top seat 7, and threaded sleeves 9 are respectively threadedly connected to the bidirectional lead screw 8. Positioning plates 10 are respectively provided on both sides of the bottom end of the top seat 7. The two positioning plates 10 are respectively located on both sides of the width direction of the anti-collision guardrail. The right side of the bidirectional lead screw 8 passes through the right side of the outside of the top seat 7 and is fixed with a turning handle 11. The top end of the positioning plate 10 is installed and fixed between a bolt member and the bottom end of the threaded sleeve 9.

[0045] Specifically, Figure 1 and Figure 3 As shown, the handle 11 can be turned on the right side of the top seat 7 to drive the bidirectional lead screw 8 to rotate according to the width of the metal anti-collision guardrail. While the bidirectional lead screw 8 rotates, the threaded sleeve 9 connected by thread can be used to drive the two positioning plates 10 to move inward or outward at the bottom of the top seat 7 at the same time, that is, the distance between the two positioning plates 10 becomes smaller or larger. By using the two positioning plates 10, auxiliary positioning can be performed when installing the metal anti-collision guardrail on both sides in the width direction, so that it can be kept straight during installation. At the same time, by adjusting the spacing between the two positioning plates 10, auxiliary positioning can also be performed when installing metal anti-collision guardrails of different widths on both sides.

[0046] A handle 16 is fixedly installed on the top of the right side of the second side formwork 12. The handle 16 can drive the first side formwork 4 and the second side formwork 12 to slide along the first slide rail 3 and the second slide rail 20, thereby completing the installation auxiliary positioning work of the entire metal anti-collision guardrail in the length direction of the bridge.

[0047] Working principle: When the device of the utility model is installed and used, two groups of holes can be first opened at the top position of the bridge deck 1, and embedded pipes can be buried inside the holes. Then, two groups of fixing bolts 23 are used to penetrate the first slide rail 3 and the first base plate 2 from the second reserved holes 24 and screwed into the embedded pipes inside the bridge deck 1, so that the first base plate 2 and the first slide rail 3 can be fixedly installed on the top of the bridge deck 1. Then, when installing the second slide rail 20 and the second base plate 21 at the rear end of the first slide rail 3, first insert the plug block 18 fixed at the front end of the second slide rail 20 downward into the slot 17 inside the rear end of the first slide rail 3, and then use the connecting bolt 25 to penetrate the interior of the plug block 18 from the first reserved hole 19 and screw it into the threaded hole 22 accordingly. The second slide rail 20 and the second base plate 21 can be installed and fixed at the rear end of the first slide rail 3. The slot 17 and the plug block 18 can improve the accuracy of the combined connection between the first slide rail 3 and the second slide rail 20. There can be multiple groups of the second slide rail 20 and the second base plate 21. When installing, you only need to drill holes to install the first base plate 2 and the first slide rail 3, and there is no need to drill holes when extending the installation later. The first side template 4 and the second side template 12 can use the slide groove 13 to slide forward and backward on the first slide rail 3 and the second slide rail 20 to adjust their positions. The top seat 7 can be set to align the top of the guardrail during installation, so that the multi-section guardrail can be maintained at the same height as the bottom of the top seat 7 during installation to maintain the same height. At the same time, when the sliding template is installed and used, the locking rod 15 can be loosened from the inside of the screw hole 14 at the top of the left side of the first side template 4 and the top of the right side of the second side template 12 respectively, and the insert 6 can be unlocked inside the inner groove 5. After that, the top seat 7 can be lifted up at the top of the first side template 4 to drive the insert 6 to extend upward from the inside of the inner groove 5. After adjusting the height of the top seat 7 to match the height of the metal anti-collision guardrail, re-tighten the locking rod 15 inside the screw hole 14. Through the template device with adjustable use height, some metal guardrails of different heights can be assisted in installation and use. When the template device is in use, the turning handle 11 can be turned on the right side of the top seat 7 to drive the bidirectional lead screw 8 to rotate according to the width of the metal guardrail. While the bidirectional lead screw 8 rotates, the threaded sleeve 9 connected by the thread can be used to drive the two sets of positioning plates 10 to move inward or outward at the bottom of the top seat 7 at the same time. By using the two sets of positioning plates 10, auxiliary positioning can be performed on both sides of the metal guardrail during installation, so that it can remain straight during installation.
