[0002] During the construction of concrete building projects, it is often encountered that due to design requirements, construction conditions or structural characteristics, some structures or situations cannot be completed in one pouring, and thus a secondary pouring is required. This type of structural part formed by the second pouring after the main structure construction is completed is called a secondary structure.

[0003] Especially in masonry structures, the construction of secondary structures is particularly important. After the wall work is completed, key structural parts such as structural columns and ring beams need to be installed and reinforced with formwork to ensure that the subsequent concrete pouring can be accurately formed according to the design requirements. However, during the pouring of secondary structures, the reinforcement of the formwork often faces a series of technical challenges.

[0004] Existing formwork reinforcement methods usually require the configuration of a variety of different formwork fixing measures to adapt to secondary structures of different shapes, sizes and requirements. These operations are not only cumbersome but also time-consuming, seriously affecting construction efficiency. More importantly, some commonly used reinforcement measures may cause damage to the completed masonry walls during implementation, thereby affecting the stability and safety of the entire structure.

[0016] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0017] The following will clearly and completely describe the concept, specific structure and technical effects of the utility model in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, other embodiments obtained by technicians in this field without creative work are all within the scope of protection of the utility model. In addition, all the connection / connection relationships involved in the patent do not refer to the direct connection of components, but refer to the formation of a better connection structure by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the creation of the utility model can be combined interchangeably without conflicting with each other.

[0018] As mentioned above, the main method for fixing the existing masonry wall structural column formwork is: after the structural column reinforcement is tied and the wall is built, the formwork is fixed, and then wooden planks are used to connect and fix the formwork, and finally clamps or tension screws are used to penetrate the wall to fix the formwork.

[0019] However, this approach has the following disadvantages:

[0020] (1) The formwork fixing measure requires drilling holes in the completed masonry wall, which damages the masonry wall and creates quality risks for subsequent plastering and decoration. In particular, the structural columns of the exterior wall are prone to water seepage;

[0021] (2) Uneven tightening force during installation of through-wall bolts can easily lead to deformation and displacement of the formwork, which in turn can cause leakage of concrete during pouring of structural columns, causing quality defects in concrete molding;

[0022] (3) The tension screws are fixed with steel pipe supports, which are too complicated to operate, and the construction and installation efficiency is low. They are easy to miss during tightening, and the clamp fixing force is insufficient. The mold is very easy to expand during pouring and cannot be fully vibrated, resulting in poor pouring quality of the structural column and excessive honeycombing and rough surfaces.

[0023] Based on this, the utility model provides a masonry structural column formwork reinforcement device, such as Figure 1 As shown, it includes: a limit member 1, a fastening plate 2 and a tension screw 3, the limit member 1 is used to fit tightly with the template to ensure the stability of the reinforcement device, the limit member 1 is fixedly connected to the tension screw 3, a through hole is opened in the center of the fastening plate 2 for the tension screw 3 to pass through, and a rotating member 4 for adjusting the fastening plate 2 is provided on the fastening plate 2, and a nut 41 is provided at the center of the rotating member 4 opposite to the tension screw 3.

[0024] When a masonry structural column needs to be fixed by formwork, first assemble the formwork and the wooden planks, determine the pulling position for fixing the formwork and punch holes, and then perform a preliminary simple fixation; insert the pulling screw 3 of the reinforcement device into the sleeve, and then pass it through the hole on the formwork, the limit piece 1 on one side is in close contact with the formwork, and then install the fastening plate 2 on the other side for preliminary fastening; after the preliminary installation of the fixing device on the structural column is completed, the fastening plate 2 is driven close to the surface of the formwork by rotating the rotating part 4 to achieve final tightening and fixation.

[0025] In an exemplary embodiment, the limit member 1 comprises a 500 mm rectangular steel with a cross-section of 60 mm×60 mm×4 mm, the fastening plate 2 is a circular steel plate with a diameter of 500 mm and a thickness of 6 mm, the tension screw 3 is an M14 bolt, and the tension screw 3 is welded to the square steel.

[0026] Through the above embodiments, the reinforcement device provided by the present application avoids the disadvantages of opening holes in the wall in the existing measures, and effectively ensures the construction quality of the masonry wall; bolts are used for tightening and positioning, so that the tension screws can be freely adjusted according to the actual needs of the construction site, which greatly expands the scope of application and repeatability of the device.

[0027] In an exemplary embodiment, if Figure 2 As shown, the entire tensioning screw rod 3 is a threaded section. Based on this, the fastening plate 2 can be flexibly adjusted according to the actual construction situation, greatly improving the scope of application.

[0028] In an exemplary embodiment, if Figure 2-3As shown, the rotating member 4 is a circular hand wheel with a smooth surface, and the circular hand wheel is welded to the fastening plate 2 through three evenly distributed brackets. In another possible implementation, the rotating member can also be in other shapes, or in a disc shape, which is not specifically limited here.

[0029] Through the above embodiments, the rotating member 4 is used to extend the lever arm, thereby reducing the force required for adjusting the fastening plate 2, thereby greatly improving the construction efficiency.

[0030] In an exemplary embodiment, the nut 41 is welded to the rotating member 4 through three evenly distributed brackets, the nut 41 and the center of the fastening plate 2 are located on the same axis, and the tension screw 3 passes through the central through hole of the fastening plate 2 and is threadedly connected to the nut 41. In another possible implementation, the nut 41 can also be welded to the center of the disc-shaped rotating member 4, or the nut 41 can also be welded to the fastening plate 2 through evenly distributed brackets, which does not constitute a specific limitation here.

[0031] Through the above embodiments, the masonry structural column formwork reinforcement device provided by the present application only requires one person to complete the reinforcement of the structural column when reinforcing the masonry structural column formwork, thereby greatly improving the construction efficiency; at the same time, the use of tension screws for installation enables the tension screws to be flexibly adjusted according to the different sizes of the wall, and has strong applicability and reusability; the formwork is clamped by limit members and fastening plates without the need for directional adjustment, and in actual engineering use, the reliability of the fixation of the structural column formwork can be guaranteed, and the quality of concrete molding can be fully guaranteed.

[0032] The above is a specific description of the preferred implementation of the utility model, but the invention of the utility model is not limited to the described embodiments.
