Description

Technical Field

[0001] This application belongs to the field of building construction formwork reinforcement technology, specifically involving a variable angle formwork reinforcement system that can be applied to the reinforcement of external corners of structural columns without penetrating walls. Background Technology

[0002] Reinforced concrete structural columns are reinforced concrete columns installed in masonry walls (such as brick walls and block walls) according to design requirements. They typically work in conjunction with ring beams and wall tie bars to enhance overall integrity, stability, and seismic performance. Structural columns are non-load-bearing components, primarily responsible for shear resistance, wall confinement, and preventing crack propagation.

[0003] From a construction perspective, the construction of structural columns in post-construction infill walls is prone to common quality problems due to the limited working space, such as grout leakage, formwork bulging, honeycombing, and large deviations in verticality. Particularly in areas where reinforcement is needed at the external corners of structural columns, issues such as formwork bulging, formwork displacement, and failure to protect the finished wall during formwork erection frequently lead to large deviations in wall flatness, increasing the thickness of the plaster layer and wasting raw material resources. Utility Model Content

[0004] The purpose of this application is to provide a variable-angle formwork reinforcement system that solves the problems of poor reinforcement effect and lack of adjustability of existing structural column formwork.

[0005] The objective of this application is achieved through the following technical solution:

[0006] A variable-angle template reinforcement system includes a first reinforcement rod, a second reinforcement rod, and a wall. One end of the first reinforcement rod is hinged to one end of the second reinforcement rod via a hinge connector. The other ends of both the first and second reinforcement rods are connected to tie rods. A template is provided on the outside of the pouring area of ​​the wall. Both the first and second reinforcement rods support the template with square timber back braces.

[0007] Furthermore, both the first reinforcing rod and the second reinforcing rod are hollow flat steel.

[0008] Furthermore, the hinge is a bolt assembly.

[0009] Furthermore, the tie rod is inserted into the toothed joint of the pouring area.

[0010] Furthermore, one end of the first reinforcing rod is provided with a first hinge plate, and one end of the second reinforcing rod is provided with a second hinge plate. Both the first and second hinge plates are provided with hinge holes for the hinge components to pass through.

[0011] Furthermore, the first hinge plate and the second hinge plate are each arranged in a plurality of pieces, the distance between two adjacent first hinge plates is equal to the thickness of the second hinge plate, and the distance between two adjacent second hinge plates is equal to the thickness of the first hinge plate.

[0012] Furthermore, both the other end of the first reinforcing rod and the other end of the second reinforcing rod are provided with screw holes for the tie rods to pass through.

[0013] Furthermore, the first and second reinforcing rods are arranged horizontally, while the square timber back braces are arranged vertically.

[0014] Furthermore, the template is a bending template.

[0015] Furthermore, the casting area formed on the wall is the casting area for structural columns.

[0016] The beneficial effects of this application are:

[0017] 1. It reduces the risk of wall cracking caused by wall penetration and avoids the risk of water seepage due to weak areas created by holes in the wall.

[0018] 2. It increases the applicability, convenience, and economy of formwork for external corners of structural columns, thereby improving construction efficiency and quality.

[0019] 3. The modular connection with adjustable angles can adapt to the construction needs of structural columns at different angles, thus improving construction flexibility.

[0020] 4. The hollow flat steel tube design reduces the weight of the components, making them easier to handle and install.

[0021] 5. The screw connection method is simple and reliable, easy to disassemble and reuse, and reduces construction costs.

[0028] The present application will be further described below with reference to specific embodiments and accompanying drawings.

[0029] Example

[0030] refer to Figures 1-4 As shown, a variable-angle template reinforcement system includes a first reinforcing rod 1, a second reinforcing rod 2, a hinge 3, a tie rod 4, a first hinge plate 5, a second hinge plate 6, a hinge hole 7, a screw hole 8, a square timber backing 9, a template 10, a wall 11, and a pouring area 12.

[0031] The first reinforcing rod 1 and the second reinforcing rod 2 are the main reinforcing support members. One end of the first reinforcing rod 1 is hinged to one end of the second reinforcing rod 2 through the hinge 3, so that the two reinforcing rods can open and close relative to each other and rotate to adjust and change their angles to match different support angles.

[0032] The other end of the first reinforcing rod 1 and the other end of the second reinforcing rod 2 are both connected to the tie rod 4. The tie rod 4 pulls on the reinforcing rod, so that the reinforcing rod has an inward supporting effect to meet the support requirements of the inner template and other components.

[0033] The wall 11 is a completed building structure, and a pre-reserved pouring area 12 is provided on the wall 11 to await subsequent pouring operations. A formwork 10 is provided on the outside of the pouring area 12 of the wall 11. Both sides of the formwork 10 are attached to the surface of the wall 11. The formwork 10 is used to enclose the pouring area 12 to ensure the sealing of the pouring area 12, so as to realize the subsequent grouting operation.

[0034] Both the first reinforcing rod 1 and the second reinforcing rod 2 support the template 10 through the square timber backing 9. That is, after the tie rod 4 pulls the reinforcing rod, the reinforcing rod then transmits the force to the inner template 10 through the square timber backing 9, thereby providing uniform and reliable support for the template 10 and preventing the template 10 from bulging or running.

[0035] Both the first reinforcing rod 1 and the second reinforcing rod 2 are hollow flat steel. The hollow flat steel tube design reduces the weight of the components and facilitates handling and installation. The hinge 3 is a bolt assembly, which achieves a reliable hinge between the two reinforcing rods through bolts and nuts, preventing the hinge from falling off.

[0036] The tie rod 4 is inserted into the toothed joint of the pouring area 12, that is, the end of the wall 11 is pre-reserved with toothed joints. Inserting the tie rod 4 into the toothed joint of the pouring area 12 (not into the wall) reduces the risk of the wall being disturbed and cracked later due to the penetration of the wall, and avoids the risk of water seepage due to weak areas caused by holes in the wall.

[0037] A first hinge plate 5 is welded to one end of the first reinforcing rod 1, and a second hinge plate 6 is welded to one end of the second reinforcing rod 2. Both the first hinge plate 5 and the second hinge plate 6 are provided with hinge holes 7 for the hinge component 3 to pass through. That is, the two reinforcing rods achieve specific hinge opening and closing through the hinge plates, avoiding the interference problem at the end of the reinforcing rod of the flat steel structure.

[0038] Several first hinge plates 5 and second hinge plates 6 are arranged in each group. The distance between two adjacent first hinge plates 5 is equal to the thickness of a second hinge plate 6, and the distance between two adjacent second hinge plates 6 is equal to the thickness of a first hinge plate 5. When a first hinge plate 5 is inserted between two second hinge plates 6, and a second hinge plate 6 is simultaneously inserted between two first hinge plates 5, the first and second hinge plates are stacked and fitted together. Tightening the hinge member 3 of the bolt assembly secures the hinge plates, fixing the hinge angle and ensuring angle stability during reinforcement. Similarly, even without locking the hinge angle of the reinforcement rod, the rod remains stable due to the pulling action of the pull screw 4; however, locking the angle makes it even more stable.

[0039] Both the other end of the first reinforcing rod 1 and the other end of the second reinforcing rod 2 are provided with screw holes 8 for the tie rod 4 to pass through, so as to realize the installation of the tie rod 4.

[0040] The first reinforcing rod 1 and the second reinforcing rod 2 are arranged horizontally. Several sets of reinforcing components formed by the first reinforcing rod 1 and the second reinforcing rod 2 are arranged at equal intervals along the height direction to ensure uniform support. The square timber back bracing 9 is arranged vertically, preferably with two bracing rods arranged on the inner side of both sides to ensure uniform support.

[0041] If template 10 is a one-piece bent template, then the first reinforcing rod 1 and the second reinforcing rod 2 need to adjust their opening and closing angles according to the bending angle. The pouring area 12 formed on the wall 11 is the pouring area for the structural column, thereby reinforcing the structural column template.

[0042] The workflow of this application is as follows: First, a formwork 10 and a square timber backing 9 are installed at the pouring area 12 of the wall 11. Then, the reinforcement components are assembled. The first reinforcement rod 1 and the second reinforcement rod 2 are combined and connected by hinges 3. Tie rods 4 are installed on the formwork 10 and positioned at the toothed joint. The first reinforcement rod 1 and the second reinforcement rod 2 are placed on the square timber backing 9 on the outside of the formwork 10. The angle between the two reinforcement rods is adjusted, and then the bolts on the tie rods 4 are tightened. Following the above method, several reinforcement components are arranged at equal intervals along the height direction. Finally, concrete is poured inside the formwork 10, and after pouring, each component is removed sequentially.

[0043] The foregoing basic examples and their further alternative examples can be freely combined to form multiple embodiments, all of which are embodiments that can be adopted and claimed in this application. In the scheme of this application, each alternative example can be arbitrarily combined with any other basic example and alternative example.

[0044] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
