DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0018] Please refer to Figures 1-4, the present invention provides a technical solution: a plastic formwork laying-out positioning tool and its usage method, including a scale plate 1. At both ends of the scale plate 1, L-shaped brackets 2 are symmetrically arranged. On the upper crossbar of the L-shaped bracket 2, threaded rods 3 are correspondingly connected by threads. A plurality of threaded sleeves 4 connected by threads are equidistantly arranged on the threaded rod 3. Rotating rings 41 are movably arranged in the middle of the threaded sleeves 4. At the upper end of the rotating ring 41, limit hooks 42 are provided. Positioning shaft rods 5 are inserted through the limit hooks 42. At both ends of the positioning shaft rod 5, connection blocks 52 are symmetrically welded. Positioning columns 6 are movably inserted in the middle of the connection blocks 52. At the upper end of the positioning column 6, a connection head 61 integrally formed and connected is provided. A positioning spring 62 wrapped around the positioning column 6 is connected between the connection head 61 and the connection block 52.

[0019] Further, the lower end of the L-shaped bracket 2 is inserted into the scale plate 1, and a locking bolt 21 is installed at the lower end of the L-shaped bracket 2, and the locking bolt 21 is embedded at the bottom of the scale plate 1. When installing the L-shaped bracket 2, the L-shaped bracket 2 and the bottom of the scale plate 1 are locked by the embedded locking bolt 21, which is convenient for the scale plate 1 to be placed flat, so as to facilitate the next laying-out positioning of the plastic formwork.

[0020] Further, a scale positioning rod 43 is provided at the lower end of the rotating ring 41, and the end of the scale positioning rod 43 corresponds to the scale line on the scale plate 1. By rotating and adjusting the distance of a plurality of rotating rings 41 and comparing the scale line with the scale positioning rod 43, equidistant distribution is realized, which is convenient for equidistant laying-out of the plastic formwork and ensures that the cross-sectional dimensions of the ribbed beams are consistent after casting and forming.

[0021] Further, both the scale positioning rod 43 and the limit hook 42 are arranged in an integrally formed connection structure with the rotating ring 41. By providing the rotating ring 41 and the rotating connection between the rotating ring 41 and the threaded sleeve 4, when adjusting the distance between a plurality of threaded sleeves 4, it is convenient to ensure that the scale positioning rod 43 and the limit hook 42 are in a vertical state, so that the positioning shaft rod 5 can be inserted into the notch of the limit hook 42 for installation.

[0022] Further, limit rings 51 are symmetrically arranged in the middle of the positioning shaft rod 5, and the opposite ends of the limit rings 51 contact the limit hooks 42. The limit rings 51 with a symmetrical structure are clamped on both sides of the limit hooks 42 to ensure that the positioning shaft rod 5 is always in a horizontal state, and further facilitate the positioning column 6 to position the center line of the plastic formwork, so as to realize the consistency of the spacing of the plastic formwork laying-out.

[0023] Specifically, first, the scale positioning rod 43 is used to compare with the scale lines on the scale plate 1, and the plurality of threaded sleeves 4 are rotated to achieve equidistant placement. Then, the plastic formwork is paid out, and the limit ring 51 on the positioning shaft rod 5 is pulled up. Under the pulling force of the positioning spring 62, the positioning shaft rod 5 is positioned at the center line of the upper end of the plastic formwork, thereby realizing the pay-out of the plastic formwork. This pay-out positioning tool can simultaneously achieve the pay-out and positioning of two rows of plastic formworks, with simple operation, avoiding the problem of deviation in the cross-sectional size of the ribbed beam after casting and ensuring the appearance quality of the overall ribbed floor slab.

[0024] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
