Description

Technical Field

[0001] The present invention relates to the technical field of assembled formwork, and in particular to an assembled wall column formwork fixing device. Background Art

[0002] Compared with traditional building structures, prefabricated concrete structures have a series of application advantages such as fast construction speed and guaranteed construction quality. The connection method between prefabricated walls and structural columns has gradually become the focus of the design and construction of prefabricated concrete structures.

[0003] There are many ways to connect prefabricated walls and structural columns, including sleeve connection, steel bar overlap, etc. The steel bar overlap connection method is to tie the wall steel bars and the column steel bars together for cast-in-place connection after the prefabricated wall is installed. This connection method combines the stability of traditional buildings with the rapid characteristics of prefabricated buildings. The traditional formwork support method is still used for the columns, that is, the column formwork is fixed by clamps and screws. This formwork fixing construction method continues the shortcomings of the traditional construction method of complex operation, time-consuming and labor-intensive. At the same time, the fixed support points of the column formwork in the prefabricated components are greatly restricted by the environment, which makes it inconvenient to fix the column formwork, and the positioning of the formwork is difficult to control. Summary of the Invention

[0004] In response to the shortcomings of the prior art, the present invention provides a prefabricated wall column formwork fixing device, which solves the shortcomings of the prior art formwork fixing construction method that continues the traditional construction method of complex operation, time-consuming and labor-intensive. At the same time, the fixed support points for fixing the column formwork in the prefabricated components are greatly restricted by the environment, making it inconvenient to fix the column formwork, and the positioning of the formwork is difficult to control.

[0005] According to an embodiment of the present invention, an assembled wall column formwork fixing device includes two assembled walls arranged in a straight line, a steel mesh is installed between the walls, and a column formwork is installed outside the steel mesh. It also includes a support frame, a support column, a connecting piece, a clamping plate and a rotating component. The support frames are respectively fixedly mounted on the walls on both sides of the formwork, the support columns are slidably mounted on the support frames and can be fixed on the support frames as needed, the connecting pieces are symmetrically slidably mounted on the support columns, the clamping plate is fixedly connected to the connecting piece, and the rotating component acts on the two connecting pieces to move in the same direction or opposite direction at the same time to clamp and fix the formwork.

[0006] The technical principle of the present invention is: utilize the pre-buried connection holes on the prefabricated assembled wall to fix the support frame on the prefabricated wall, slide the support column on the support frame, align the center of the support column with the center of the column, and then fix the support column on the support frame, adjust the rotating member, so that the rotating member acts on the two connecting parts to move in the same direction at the same time, driving the splint fixed on the connecting part to clamp the formwork, so that the formwork is located in the center position between the two walls, so that a cast-in-place space for the column is formed between the formwork and the wall. The installation and disassembly operations of the formwork on the prefabricated wall are more convenient and easier to operate than the traditional formwork erection. At the same time, the erection of the support frame relies on the prefabricated formwork, is less restricted by the on-site environment, the fixation of the formwork is more firm and reliable, and the positioning of the formwork is easier to locate and better controlled.

[0007] Compared with the prior art, the present invention has the following beneficial effects: fixing the support frame on the prefabricated wall, sliding the support column on the support frame, aligning the center of the support column with the center of the column, and then fixing the support column on the support frame, adjusting the rotating component, so that the rotating component simultaneously acts on the two connecting parts to move in the same direction, driving the splint fixed on the connecting part to clamp the template, which solves the shortcomings of the traditional construction method of complex operation, time-consuming and labor-intensive operation of the template. At the same time, the fixed support point of the column template in the assembled component is greatly restricted by the environment, which is inconvenient to fix the column template, and the positioning of the template is not easy to control. The technical problem results in that the installation and disassembly operations of the template on the prefabricated wall are more convenient and the operation is more convenient than the traditional template erection. At the same time, the erection of the support frame relies on the prefabricated template, which is less restricted by the on-site environment, the fixation of the template is more firm and reliable, and the positioning of the template is easier to locate and better controlled.
