Description

Technical Field

[0001] This application relates to the field of fastening device technology, and in particular to a bracing and tensioning integrated opposing template fastening device. Background Technology

[0002] In civil engineering construction, formwork engineering is a crucial step in ensuring the dimensional accuracy of concrete structures, including their length and width. Opposite formwork sections need both support to prevent inward movement or collapse, and tie rods to prevent outward movement or collapse, especially during concrete pouring.

[0003] Traditional opposing formwork fastening systems, comprising supports and tie rods, typically consist of high-rigidity steel sections or pipes supported between the formwork or reinforcing ribs welded to it. Tie rods secure the opposing formwork reinforcing ribs. The supports and tie rods are either installed separately or the steel pipes are simply sleeved around the tie rods, failing to form a stable fixed structure. This results in low efficiency during formwork installation and removal, and the supports are prone to instability, causing the formwork to shift inward or even collapse. Furthermore, after tightening the tie rods, a certain length of the rod protrudes beyond the formwork reinforcing ribs, posing a risk of scraping and injury to personnel, thus compromising construction safety. Utility Model Content

[0004] Therefore, it is necessary to provide a bracing and tensioning integrated opposing template fastening device to overcome the defects mentioned in the background art.

[0005] The integrated support and tensioning counter-tempering device includes: Reinforcing ribs; Support rod, disposed between a pair of said reinforcing ribs; and A tensioning assembly is symmetrically arranged at both ends of the support rod. One end of the tensioning assembly passes through the reinforcing rib and is connected to the end of the support rod, while the other end is connected to the reinforcing rib.

[0006] As a preferred embodiment of the anti-tempering device integrating support and tension in this utility model, the end of the reinforcing rib is provided with an installation groove.

[0007] As a preferred embodiment of the anti-formwork fastening device integrating support and tension in this utility model, the mounting groove extends along the length direction of the reinforcing rib, and its bottom height is higher than the top height of the formwork.

[0008] As a preferred embodiment of the anti-formwork fastening device integrating support and tension in this utility model, the end of the support rod is provided with a groove, and a fixing component is provided in the groove.

[0009] As a preferred embodiment of the anti-tempering template fastening device integrating support and tension in this utility model, the tensioning component includes a bolt, a connecting part is provided between the thread and the head of the bolt, the thread of the bolt is connected to the fixing component in the groove, the connecting part is located in the mounting slot, and the head abuts against the reinforcing rib.

[0010] As a preferred embodiment of the anti-tempering template fastening device integrating support and tension in this utility model, a washer is provided between the head of the bolt and the reinforcing rib.

[0011] The beneficial effects of this utility model are: This utility model integrates the support rod and tensioning component into one unit, completing the support and connection simultaneously. It allows for one-time installation or dismantling, enabling construction personnel to operate quickly, improving work efficiency, reducing construction costs, and avoiding the instability risk caused by separate installation of the support and tensioning components in existing technologies. This enhances the stability of the formwork during construction, and prevents excessively long screws from extending from both sides, thus improving safety. Attached Figure Description

[0020] According to one aspect of this application, embodiments of this application provide a support-and-tension integrated opposing template fastening device, please refer to the following: Figures 1 to 4 The fastening device includes reinforcing ribs 1000, support rods 2000 and tensioning components 3000. A pair of reinforcing ribs 1000 are spaced apart. The support rods 2000 are disposed between the pair of reinforcing ribs 1000 and their ends abut against the reinforcing ribs 1000. One end of the tensioning components 3000 passes through the reinforcing ribs 1000 and is connected to the end of the support rods 2000, and its other end is connected to the reinforcing ribs 1000.

[0021] In this embodiment, the reinforcing rib 1000, the support rod 2000, and the tensioning assembly 3000 work together to both tension and support the template, avoiding the risk of instability caused by separate installation of the support and tensioning, and enhancing the stability of the template during construction.

[0022] In one embodiment, see Figure 1 and Figure 2 The reinforcing rib 1000 is set on the outside of the template, and its lower part is integrated with the template. Its upper part is provided with an installation slot 1100. This structure facilitates the installation of the support rod 2000 and the tensioning assembly 3000.

[0023] In one embodiment, the mounting slot 1100 extends along the length of the reinforcing rib 1000, and its bottom height is higher than the top height of the template, so as to avoid the support rod 2000 from contacting the concrete inside the template after installation.

[0024] In one embodiment, the end of the support rod 2000 is provided with a groove, and a fixing component is provided in the groove to facilitate the fixing of the tensioning component 3000. Hollow steel pipe can be used as the support rod 2000 on the construction site. A pull plate 2100 with a diameter slightly smaller than the inner diameter of the hollow steel pipe is processed. A circular hole slightly larger than the outer diameter of the screw is drilled in the center. Nut 2200 is concentrically welded to the pull plate 2100. The pull plate 2100 with the nut 2200 is inserted into the hollow steel pipe from the side. The pull plate 2100 is fixed by electric welding at a certain distance from the end of the hollow steel pipe. The pull plate 2100 and the nut 2200 are connected to the tensioning component 3000 as a fixing component.

[0025] In one embodiment, see Figure 3 and Figure 4 The tensioning assembly 3000 includes a bolt comprising a threaded portion 3100, a connecting portion, and a head 3200 arranged sequentially. The threaded portion 3100 connects to a fixing component within a groove, the connecting portion is located within a mounting slot 1100, and the head 3200 abuts against a reinforcing rib 1000. When the tensioning assembly 3000 is initially tightened, the threaded portion 3100 is completely within the groove and connected to the mounting slot 1100 via the connecting portion, thus preventing damage from collision between the threaded portion 3100 and the mounting slot 1100 during installation. Replacing the original threaded rod with a bolt allows for tightening or loosening using an electric wrench, facilitating installation and disassembly and significantly improving efficiency.

[0026] In one embodiment, a washer 4000 is provided between the bolt head 3200 and the reinforcing rib 1000 to ensure connection stability.

[0027] The fastening device connects the support rods 2000 and tensioning components 3000 at both ends of the reinforcing rib 1000, replacing the continuous threaded rods used in existing technologies, thus saving on the amount of threaded rods used. Simultaneously, the connection between the support rods 2000 and the tensioning components 3000 is concealed within the support rods 2000, preventing frequent corrosion due to concrete contamination from exposure, and minimizing bolt wear. Furthermore, the absence of excessively long threaded rods on both sides enhances safety.

[0028] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0029] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
