[0002] During the construction of fair-faced concrete, the situation of post-cast construction of door piers often occurs. However, due to the small size of the door piers, the difficulty of post-cast formwork support is great, and the conventional formwork support method is difficult to meet the requirements of fair-faced concrete pouring.

[0003] The traditional formwork support for door piers is constructed by using tie rods or buckles to pass through the surrounding walls. However, in the construction of fair-faced concrete, this method will damage the integrity of the surrounding fair-faced concrete walls, resulting in secondary rework, greatly increasing the construction cost, and at the same time affecting the visual effect of fair-faced concrete. Therefore, it is very necessary to design a formwork support system that conforms to the post-cast door piers of fair-faced concrete and has a good finished product protection effect.

[0006] Further, the jacking mechanism includes: a screw rod fixed on one side support plate; a support rod fixed on the other side support plate; a connecting rod rotatably arranged between the screw rod and the support rod, one end of the connecting rod is provided with a thread groove corresponding to the screw rod, and the other end is provided with a groove sleeved with the support rod.

[0007] Further, the screw rod, the support rod and the connecting rod are on the same straight line and are perpendicular to the support plates on both sides.

[0008] Further, one end of each of the two support side plates is provided with a connecting part at a right angle, and a fixing part is arranged on the connecting part, and the fixing part penetrates through the connecting part and the support plate.

[0009] Further, a plurality of strip holes are horizontally opened on the support plates, a plurality of limiting holes corresponding to the strip holes are opened on the connecting parts of the support side plates, and the fixing part penetrates through the corresponding limiting holes and strip holes.

[0010] Furthermore, a tie bolt is arranged between the two supporting side plates, and bolt holes for passing through the tie bolt are arranged on the supporting side plates.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] By arranging a jacking mechanism capable of adjusting the length, the jacking mechanism is used to push the two side supporting plates away from each other, so as to support and fix the door pier formwork with the two supporting plates, avoiding drilling holes in the already cast fair-faced wall through tie bolts, ensuring the integrity and ornamental value of the fair-faced wall surface, and avoiding secondary rework.

[0013] By arranging a screw rod and a support rod matched with the screw rod, when the support rod is screwed, the end of the screw rod can extend out of or enter the support rod, so as to realize the adjustment of the length of the whole jacking mechanism. Description of the Drawings

[0020] The following further describes the utility model in conjunction with the drawings and specific embodiments.

[0021] Refer to Figure 1, the present utility model provides a formwork support structure for a post-cast door pier, which solves the problem that the existing formwork support for the door pier is prone to damage the surrounding walls. By setting a jacking mechanism capable of adjusting the length, the jacking mechanism is used to push the support plates on both sides away from each other, so as to realize the support and fixation of the two support plates on the door pier formwork, avoiding drilling holes in the already cast fair-faced wall through tie bolts, ensuring the integrity and ornamental value of the fair-faced wall surface, and avoiding secondary rework. By setting a screw rod and a support rod cooperating with the screw rod, when the support rod is rotated, the end of the screw rod can extend out of or enter the support rod, so as to realize the adjustment of the length of the entire jacking mechanism.

[0022] The following will describe a formwork support structure for a post-cast door pier of the present utility model with reference to the accompanying drawings.

[0023] Refer to Figure 1 , which shows a schematic diagram of the installation completion of a formwork support structure for a post-cast door pier of the present utility model. The following will describe a formwork support structure for a post-cast door pier of the present utility model in conjunction with Figure 1 , and will describe a formwork support structure for a post-cast door pier of the present utility model.
