[0025] Reference Figures 1 to 3 The post-casting strip formwork support device of the utility model is implemented as follows:

[0026] A post-cast strip formwork support device comprises: a plurality of support rods 100.

[0027] A plurality of support rods 100 are arranged parallel to each other. A connecting member 200 is arranged between adjacent support rods 100 .

[0028] The connecting member 200 includes a first connecting rod 210 and a second connecting rod 220. One end of the first connecting rod 210 and the second connecting rod 220 is hinged to each other, and the other end is hinged to two adjacent supporting rods 100 respectively.

[0029] In actual use, a plurality of the support rods 100 can jointly provide support for the post-casting strip formwork. Adjacent support rods 100 are connected by the connecting member 200. When the first connecting rod 210 and the second connecting rod 220 are flipped and unfolded, the distance between the two adjacent support rods 100 can be increased; when the first connecting rod 210 and the second connecting rod 220 are flipped and folded, the distance between the two adjacent support rods 100 is reduced. The plurality of support rods 100 are connected into a whole by the connecting member 200, and can be directly unfolded when in use, without measuring the distance between adjacent support rods 100. When transporting, the plurality of support rods 100 can be folded so that they are close to each other and gathered into a ball, which is convenient for storage and transfer.

[0030] In this embodiment, the first connecting rod 210 and the second connecting rod 220 are both in the shape of cylindrical rods, and the connecting member 200 further includes a connecting sleeve 230. The connecting sleeve 230 is in the shape of a cylinder. The connecting sleeve 230 is movably sleeved on the first connecting rod 210. The connecting sleeve 230 has a connecting end 231 that is detachably connected to the second connecting rod 220.

[0031] In actual use, by connecting the connecting end 231 with the second connecting rod 220, the connecting sleeve 230 is located at the hinge position of the first connecting rod 210 and the second connecting rod 220, and is simultaneously sleeved on the outside of the first connecting rod 210 and the second connecting rod 220, so that the first connecting rod 210 and the second connecting rod 220 can be kept in the same straight line, so that the two adjacent support rods 100 can be stretched to the farthest distance.

[0032] In order to keep the plurality of support rods 100 parallel to each other, a plurality of connecting members 200 are provided between each group of two adjacent support rods 100. The plurality of connecting members 200 are arranged at equal intervals in the up-down direction between the two adjacent support rods 100. In this embodiment, two connecting members 200 are provided between the two adjacent support rods 100, and the two connecting members 200 are connected to the upper part and the lower part of the support rod 100, respectively.

[0033] In this embodiment, the connection end 231 has an internal thread, the outer periphery of the second connecting rod 220 has a corresponding external thread 221, and the connection end 231 is threadedly connected to the second connecting rod 220. The connecting sleeve 230 is fixedly connected to the second connecting rod 220 through the thread, so that the connecting sleeve 230 can remain sleeved on the hinged position of the first connecting rod 210 and the second connecting rod 220.

[0034] In some other embodiments, the connection end 231 can tighten the second connection rod 220 by a machine screw threaded in the radial direction, so that the connection sleeve 230 is fixedly connected to the second connection rod 220. In some other embodiments, the connection end 231 and the second connection rod 220 can also be connected in a limited position by a latch 140 arranged in the radial direction.

[0035] Taking the extension direction of the support rod 100 as the up-down direction, the upper and lower ends of the support rod 100 respectively have a supporting end 110 for supporting the post-casting template 500 of the peripheral device and a fixing end 120 for fixing to a reference.

[0036] In this embodiment, the support end 110 is provided with a connecting skeleton 300. The connecting skeleton 300 is rotatably connected to the support rod 100 and fixedly connected to the external post-casting template 500. The rotation axis of the connecting skeleton 300 extends in the left-right direction. The support end 110 has a U-shaped installation groove 111, and the connecting skeleton 300 has a hinged portion arranged in the installation groove 111, and the left and right side groove walls of the installation groove 111 are respectively arranged on the left and right sides of the hinged portion and are rotatably connected thereto. The connecting skeleton 300 also has a connecting plate in the shape of a flat plate. The plate surface of the connecting plate is tightly fitted with the post-casting template 500.

[0037] The fixing end 120 is provided with a fixing plate 400. The middle part of the fixing plate 400 is connected to the fixing end 120. The lower side of the fixing plate 400 is plate-shaped and is provided with through holes or threaded holes arranged in pairs on the left and right. In actual use, the fixing plate 400 is fixed through the through holes or threaded holes.

[0038] In this embodiment, the middle portion of the fixing plate 400 is detachably connected to the fixing end 120 via a connecting screw. When the plurality of support rods 100 are brought close together, the fixing plate 400 can be removed to avoid obstruction.

[0039] In some embodiments, the lower end surface of the fixing plate 400 is perpendicular to the axial direction of the support rod 100, and needs to be fixed by a plane parallel to the post-casting template 500 when in use. In some embodiments, the lower end surface of the fixing plate 400 is inclined to the axial direction of the support rod 100, and the fixing plate 400 can be fixed on the ground to achieve oblique support for the post-casting template 500.

[0040] To facilitate the transfer and handling of the post-casting strip formwork support device, in this embodiment, the fixed end 120 is provided with a retractable roller 132. The middle of the fixed plate 400 has an avoidance hole corresponding to the roller 132, and the roller 132 can extend from the avoidance hole.

[0041] In this embodiment, the roller 132 is installed through the limiting rod 130. The fixed end 120 has a cylindrical receiving groove 121 extending in the axial direction, and the receiving groove 121 has a downward opening. The limiting rod 130 is inserted into the receiving groove 121, and the roller 132 is rotatably arranged at the lower end of the limiting rod 130.

[0042] In order to facilitate the adjustment of the extension and retraction of the roller 132, a limiting ring 133 fixedly connected to the limiting rod 130 is sleeved on the outer side of the fixed end 120. The limiting ring 133 is in the shape of a circular ring. The left and right sides of the accommodating groove 121 are provided with limiting grooves 122 extending up and down. The upper end of the limiting rod 130 is provided with a connecting shaft 131 extending left and right. The left and right ends of the connecting shaft 131 are respectively arranged on the left and right sides of the limiting rod 130. The left and right ends of the connecting shaft 131 respectively penetrate the two limiting grooves 122 and are fixedly connected to the limiting ring 133.

[0043] The limiting ring 133 and the limiting rod 130 are connected to each other via a connecting shaft 131 passing through the limiting groove 122 , so that the limiting rod 130 can be extended and retracted through the axial movement of the limiting ring 133 , thereby adjusting the position of the roller 132 .

[0044] The fixed end 120 has a plurality of pin holes 123 arranged in an up-and-down arrangement. The pin holes 123 are arranged along the radial direction of the fixed end 120. The stop ring 133 is provided with a plug 140 corresponding to the pin hole 123. By inserting the plug 140 into the pin holes 123 at different positions, the relative position of the stop rod 130 and the fixed end 120 can be adjusted, thereby adjusting the extension and retraction of the roller 132.

[0045] It is worth noting that the distance from the pin hole 123 to the opening needs to be set according to the length of the limiting rod 130. When the latch 140 is inserted into the uppermost pin hole 123, the limiting ring 133 is at the upper limit position, and the limiting rod 130 and the roller 132 can be completely in the receiving groove 121. When the latch 140 is inserted into the lowermost pin hole 123, the limiting ring 133 is at the lower limit position, and the roller 132 is exposed at the lower end of the receiving groove 121.

[0046] In a further embodiment, in order to facilitate the insertion of the latch 140, the latch 140 is elastically connected to the limiting ring 133. The limiting ring 133 has a plug hole extending in the radial direction, and the latch 140 is slidably inserted into the plug hole. The end of the latch 140 away from the support rod 100 is provided with a connecting flange. A tension spring 150 is sleeved on the outer side of the latch 140. The two ends of the tension spring 150 are respectively fixedly connected to the connecting flange and the limiting ring 133, so that the latch 140 has a tendency to move relative to the limiting ring 133 toward the direction close to the fixed end 120.

[0047] In actual use, the latch 140 is pulled out to disengage from the pin hole 123, so that the limit ring 133 can move axially relative to the support rod 100, and the limit rod 130 is adjusted to be telescopic, thereby adjusting the position of the roller 132. When the limit ring 133 moves to a specific position and the latch 140 is aligned with the corresponding pin hole 123, the latch 140 is released, and the latch 140 is inserted into the pin hole 123 under the force of the tension spring 150, so that the limit ring 133 is connected to the fixed end 120, and the telescopic adjustment is completed.
