[0023] See also Figures 1 to 3 The present embodiment provides a bridge guardrail reserved platform construction device, comprising a first hanger 1, a second hanger 2 and a template seat 3. The second hanger 2 is arranged opposite to the first hanger 1 and is spaced apart by a preset distance, which is slightly smaller than the length of the template seat 3.
[0024] The two ends of the template seat 3 are respectively arranged on the first hanger 1 and the second hanger 2, and the template seat 3 is suspended in the air by the first hanger 1 and the second hanger 2. The first end of the template seat 3 is rotatably connected to the lower part of the first hanger 1, and the second end of the template seat 3 is fixedly connected to the lower part of the second hanger 2. The second hanger 2 can drive the second end of the template seat 3 to rotate around the first end of the template seat 3. Specifically:
[0025] The first hanger 1 comprises a first bottom bar 11, a movable sleeve 12 and two first vertical bars 13. The first bottom bar 11 is connected between the lower parts of the two first vertical bars 13. The movable sleeve 12 is movably sleeved on the first bottom bar 11 and can rotate around the first bottom bar 11. The first end of the template seat 3 is fixedly connected to the movable sleeve 12, so that the template seat 3 can rotate around the first bottom bar 11 following the movable sleeve 12.
[0026] The second hanger 2 includes a second bottom bar 21 and two second vertical bars 22, and the second bottom bar 21 is connected between the lower parts of the two second vertical bars 22. The second end of the template seat 3 is fixedly connected to the second hanger 2. Specifically, the bottom wall 31 of the template seat 3 is fixedly connected to the second bottom bar 21, and the side wall 32 of the template seat 3 is fixedly connected to the corresponding second vertical bar 22, so that the construction personnel can drive the template seat 3 to rotate around the movable sleeve 12 through the second hanger 2.
[0027] The template base 3 includes a bottom wall 31 and two side walls 32. The two side walls 32 are arranged opposite to each other. The bottom wall 31 is connected between the two side walls 32. The bottom wall 31 and the two side walls 32 form a U-shaped structure with two open ends. The first end of the template base 3 is detachably connected to a baffle 4, which blocks the open end of the template base 3. The second end of the template base 3 is provided with an opening 33, which is arranged opposite to the baffle 4, and a casting cavity is formed between the template base 3 and the baffle 4. When it is necessary to cast concrete, the end of the template base 3 with the opening 33 is directed toward the bridge guardrail 7 so that the opening 33 is closely fitted with the side wall 32 of the bridge guardrail 7, and the opening 33 is blocked by the side wall 32 of the bridge guardrail 7.
[0028] The baffle 4 is connected to the bottom wall 31 through the connecting assembly 5 and is arranged between the two side walls 32. Specifically, the connecting assembly 5 includes a threaded rod 51, two pressing blocks 52 and two nuts 53. The two ends of the threaded rod 51 extend toward the two side walls 32 respectively, and the threaded rod 51 is arranged on the outside of the baffle 4 and adjacent to the baffle 4; the two pressing blocks 52 are respectively connected to the two ends of the threaded rod 51, and the nuts 53 lock the corresponding pressing blocks 52 on the threaded rod 51. In this embodiment, the distance between the two pressing blocks 52 is adjustable, and the two pressing blocks 52 are respectively arranged on the outside of the two side walls 32. The distance between the two pressing blocks 52 is manually adjusted to clamp and fix them on the two side walls 32, and the threaded rod 51 is used to prevent the baffle 4 from tipping outward.
[0029] When the mold needs to be removed, first loosen the two nuts 53 and move the two pressing blocks 52 relatively away from each other, then remove the entire connecting assembly 5, and then remove the baffle 4 to prepare for the subsequent rotation of the mold base 3.
[0030] In order to facilitate the removal of the baffle 4, the upper part of the baffle 4 protrudes from the top surface of the side wall 32, so that after pouring the concrete, the upper part of the baffle 4 protrudes from the concrete surface, making it convenient for construction workers to knock the baffle 4 outward with tools such as hammers to separate the baffle 4 from the concrete.
[0031] The template base 3 and the baffle plate 4 can both be made of wooden boards, or the template base 3 and the baffle plate 4 can both be made of metal plates.
[0032] See also Figures 4 to 6 , and combined with Figure 1 The first hanger 1 and the second hanger 2 are erected between two adjacent bridge guardrails 7 through two parallel supporting rods 6, the two ends of the supporting rod 6 are respectively overlapped on the two bridge guardrails 7, and the template seat 3 is suspended between the two bridge guardrails 7.
[0033] A first cross beam 14 is disposed on the upper portion of the first hanger 1 , and a second cross beam 23 is disposed on the upper portion of the second hanger 2 . Both the first cross beam 14 and the second cross beam 23 are overlapped on the two support rods 6 .
[0034] Before pouring concrete, the construction device of this embodiment is suspended between two bridge guardrails 7 by the support rod 6, and one end of the opening 33 of the formwork seat 3 is directed toward one side of the bridge guardrail 7 so that the opening 33 is tightly fitted with the side wall 32 of the bridge guardrail 7 on that side, and the opening 33 is blocked by the side wall 32 of the bridge guardrail 7; then the concrete is poured; when the formwork needs to be removed after the concrete solidifies, the connecting assembly 5 and the baffle 4 can be removed first; then the support rod 6 is removed, at which time the construction personnel can stand on the bridge, hold the upper part of the first hanger 1, and then apply a downward force to the upper part of the second hanger 2, and drive the second end of the formwork seat 3 to rotate downward through the second hanger 2, so as to separate the formwork seat 3 from the concrete, and then the construction personnel carry the first hanger 1 by hand, first move it horizontally and then lift up the entire construction device.
[0035] In order to facilitate construction workers to hold, a protrusion 15 is also provided on the upper part of the first hanger 1. The protrusion 15 is higher than the first cross beam 14. The two ends of the protrusion 15 are respectively fixedly connected to the upper parts of the two first vertical rods 13, or the protrusion 15 and the two first vertical rods 13 are integrally formed.
[0036] In summary, the utility model provides a first hanger and a second hanger for suspending the formwork seat on the outside of the bridge guardrail so that the open end of the formwork seat is in close contact with the side wall of the bridge. After concrete is poured in the formwork seat, the concrete will form a reserved platform on the side wall of the bridge. By providing a baffle, the concrete can be blocked from flowing outward when pouring concrete. When removing the formwork, the baffle is first removed to prevent the baffle from blocking the rotation of the formwork seat. By providing the second hanger, the formwork seat can be driven to rotate. When removing the formwork, the construction personnel can stand on the bridge and hold the first hanger to lift the entire construction device. Then, by applying a downward force to the upper part of the second hanger, the second hanger and the formwork seat are both rotated downward around the lower part of the first hanger to separate the formwork seat from the concrete. At this time, the construction personnel can drive the formwork seat and the second hanger to translate through the first hanger to move out from under the reserved platform, so as to facilitate the lifting of the entire construction device and the construction operation of the next reserved platform.
