Description

Technical Field

[0001] The present invention belongs to the technical field of construction, and particularly relates to an adjustable formwork device applied to an arch masonry system. Background Art

[0002] As a representative of the beauty of curves in architecture, the arch is one of the earliest forms used. Whether in Eastern civilization or Western civilization, the existence of the arch not only brings flowing changes to the building, but also carries the perceptual meaning of the combination of grandeur and softness. When the arch bears gravity, it can naturally transfer the pressure downward and outward to adjacent parts, and the arch bodies are squeezed against each other, combining more tightly. In modern construction, when facing an arch masonry structure, wooden formwork is often used for support, and the arch body is built with blocks such as bricks, stones, and adobe. The stability of the support structure will directly affect the construction quality of the arch structure. In mild cases, the appearance is not good, and in severe cases, problems such as dislocation and wall cracking will occur.

[0003] On-site template production is generally manual work, with low precision and a cumbersome process. The same project generally involves the same number or different numbers of arch structures. For the same number of arch structures, the formwork needs to be made or the previously used formwork needs to be removed multiple times, which is time-consuming and laborious; and to adapt to different arch structures, new formwork needs to be made again. Therefore, the on-site produced formwork has a small scope of application, cannot meet arch structures of various scales, and is troublesome to disassemble and assemble, which is not conducive to turnover use.

Then, the bearing assembly 6 is used to support the resilient strip 3. Finally, arch - shaped structure masonry can be carried out on the resilient strip 3. It is not only reasonable in structural design and convenient to use, but also does not require template making. Specific Embodiment Two:

[0032] On the basis of Specific Embodiment One, as Figure 2-7As shown in the figure, a plurality of guiding holes 401 are radially formed on the arc-shaped frame 4; the jacking assembly 5 includes a plurality of jacking rods 501 respectively and slidably inserted into the guiding holes 401; the plurality of jacking rods 501 are connected by a lifting driving member; the lifting driving member is installed on the inner side of the arc-shaped frame 4; one end of the jacking rod 501 abuts against the inner surface of the resilient strip 3; the lifting driving member includes a servo motor 503 fixed on the upper surface of the workbench 1; on one side of the servo motor 503, a pair of mounting seats 504 are fixed side by side along the axial direction of the arc-shaped frame 4; the two mounting seats 504 are respectively arranged on the opposite sides of the arc-shaped frame 4; a guiding rail 505 is fixed between the two mounting seats 504; a bidirectional threaded rod 506 is arranged in parallel below the guiding rail 505; the two ends of the bidirectional threaded rod 506 are respectively rotatably connected to the two mounting seats 504; one end of the bidirectional threaded rod 506 is connected to the output shaft of the servo motor 503 through a conventional belt driving member 507 in the art; the belt driving member 507 is composed of a protective shell, a pair of pulleys arranged side by side in the protective shell, and a belt for drivingly connecting the two pulleys; movable blocks 508 are in threaded engagement with both threaded sections of the bidirectional threaded rod 506; the upper part of the movable block 508 is slidably sleeved on the guiding rail 505; a plurality of transmission rods 509 corresponding to the jacking rods 501 are rotatably connected to the upper surface of the movable block 508; one end of the transmission rod 509 is rotatably connected to the lower end of the jacking rod 501; a pair of protective strips 5041 are arranged side by side between the two mounting seats 504; the two protective strips 5041 are respectively arranged on the opposite sides of the guiding rail 505; the two ends of the protective strip 5041 are respectively connected to the two mounting seats 504.
