Description
Technical Field
[0001] The utility model belongs to the technical field of the offset of the fixed steel formwork for pier columns, and particularly relates to a positioning and reinforcement device for controlling the offset of the fixed steel formwork for pier columns. Background Art
[0002] The connection of the fixed steel formwork for pier shafts adopts bolt connection. During the construction process, it is inconvenient to align the hole positions. If there is a slight deviation, the bolts will not be able to pass vertically through the hole positions, and the process of tightening the bolts is time-consuming and laborious; there is a gap between the bolt holes and the bolts, which is likely to cause inaccurate hole positions. When the bolts are forcibly tightened, the formwork will be displaced, and the physical strength of workers is consumed relatively greatly during the process of tightening and removing the bolts. There are certain safety hazards in long-term high-altitude operations; during the construction, it is necessary to strictly control the formwork joints of the pier columns to ensure that there is no obvious offset after the formwork of the pier columns is removed and the appearance quality of the pier columns is guaranteed.
[0003] After retrieval, an engineering steel formwork offset adjustment device with the prior art publication number of CN215803253U includes a formwork clamping member, a formwork moving member and a moving limiting member. The formwork clamping member is used to clamp adjacent two formworks and fix the non-protruding formwork. The formwork moving member is slidably connected with the formwork clamping member and can move the protruding formwork towards the direction close to another formwork. The moving limiting member is slidably connected with the formwork clamping member. The moving limiting member includes an elastic member and a limiting block. The bottom wall of the limiting block is attached to the top wall of the protruding formwork, and the side wall of the limiting block is attached to the side wall of another formwork. One end of the elastic member is connected with the formwork clamping member, and the other end is fixedly connected with the limiting block. The formwork moving member is provided with a limiting groove for accommodating the limiting block, and the end of the limiting groove close to the formwork is open; its processing process has the following disadvantages: the formwork is moved and adjusted through the adjustment device to align adjacent formworks, but after the adjustment is completed, the formwork cannot be correspondingly positioned and fixed in time. Under the action of a certain external force, the formwork will be displaced again, resulting in an offset.
[0004] After retrieval, a pier fixed steel formwork joint adjustment device with the prior art publication number of CN213571556U includes: paired adjustment members; the adjustment members include: clamping members, fastening members and adjusting members; the clamping members are frame structures with openings for placing the respective connecting members of two spliced steel formworks; the fastening members are arranged on the top of the clamping members; the adjusting members are arranged on one side of the clamping members for tightly pressing the two connecting members from one side, so as to align the edges of the two connecting members; its processing process has the following disadvantages: there is a gap between the hanging members and the bolt holes, which is likely to cause inaccurate hole positions, resulting in forced tightening of the bolts and causing the formwork to be displaced.
