Abstract
Description
Technical Field
[0001] This utility model relates to the field of template clamping technology, specifically a lateral template reinforcement device for cantilever slabs in concrete structures. Background Technology
[0002] Structural cantilever slabs are an important element in architectural design, typically used to enhance both the aesthetics and functionality of a building. A cantilever slab refers to the outward extension of a building's exterior surface, often used for sun shading, improving lighting, and increasing the sense of space.
[0003] To meet the demand for diverse architectural styles, most buildings are designed with decorative structural cantilever slabs. Some of these cantilever slabs have relatively long cantilever lengths and widths. In such cases, reinforcing the side formwork of the structural cantilever slabs is difficult and time-consuming. Furthermore, traditional reinforcement methods result in significant wear and tear on the formwork. Consequently, the concrete on the sides of the cantilever slabs after construction is poorly formed, increasing the likelihood of secondary processing and compromising the quality of the concrete. Utility Model Content
[0004] The purpose of this utility model is to provide a reinforcement device for the side formwork of a concrete structure cantilever slab. By setting up a formwork support frame with steel keel, arc-shaped steel pipe, arc-shaped steel pipe, B-plate and steel internal bracing, it solves the problem that most buildings are designed with decorative structural cantilever slabs, and some structural cantilever slabs have relatively long cantilever lengths and widths. In these cases, the side formwork reinforcement of the structural cantilever slab is difficult, time-consuming, and traditional reinforcement methods cause significant wear and tear on the formwork. The concrete forming effect on the side of the cantilever slab after construction is poor, and there is a high possibility of secondary processing, which is not conducive to ensuring the quality of concrete forming.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a lateral formwork reinforcement device for a cantilever slab of a concrete structure, comprising a steel keel for a formwork support frame, an arc-shaped steel pipe sleeved on the surface of the steel keel for the formwork support frame, assembly plates fixedly connected to both sides of the arc-shaped steel pipe, multiple holes opened on the surface of the assembly plates, bolts inserted into the interior of each of the multiple holes, a nut for fixing a steel plate A threaded to one end of each bolt, a steel plate B welded to one side of the upper surface of the steel plate A, and an inner steel brace welded to one side of the steel plate B.
[0006] Preferably, the bottom end of the steel inner support is welded to the other side of the upper surface of steel plate A, and the diameter of the steel inner support is 20mm.
[0007] Preferably, the bottom end of the bolt is provided with a nut, which is welded to the lower surface of the assembly plate.
[0008] Preferably, a timber A is overlapped on one side of the upper surface of the steel keel of the template support frame, and a template is overlapped on the upper surface of the timber A.
[0009] Preferably, a B-shaped timber is overlapped on the other side of the upper surface of the template, and the B-shaped timber is in close lateral contact with the template.
[0010] Preferably, one side of the B timber is in close contact with the B steel plate, and the inside of the arc-shaped steel pipe is provided with anti-slip teeth.
[0011] This utility model provides a lateral formwork reinforcement device for cantilever slabs in concrete structures, which has the following beneficial effects:
[0012] This equipment allows for flexible adjustment of the reinforcement position of the side formwork. By loosening the nuts, the curved steel pipe and steel plate A can be moved flexibly on the steel keel of the formwork support frame. After adjusting to the appropriate position, tightening the nuts, in conjunction with the anti-slip teeth, fixes steel plate A to the steel keel of the formwork support frame. This enables efficient reinforcement of timber A and timber B during the construction of the cantilever slab, increasing the turnover rate of the formwork while ensuring the molding quality of the side concrete. This saves time on formwork reinforcement, reduces the input of construction personnel, ensures the stability of the side formwork, and guarantees the molding quality of the side concrete of the cantilever slab. Thus, it achieves the goals of saving construction time, reducing project personnel costs, increasing the turnover rate of the formwork, ensuring the stability of the side formwork, and guaranteeing the molding quality of the side concrete of the cantilever slab.

When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.
[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this embodiment proposes a lateral formwork reinforcement device for a cantilever slab of a concrete structure, including a formwork support frame steel keel 1. An arc-shaped steel pipe 2 is sleeved on the surface of the formwork support frame steel keel 1. The arc-shaped steel pipe 2 is made of steel pipe with a radius of 25mm. Assembly plates 3 are fixedly connected to both sides of the arc-shaped steel pipe 2. Multiple holes are opened on the surface of the assembly plate 3. Bolts 4 are inserted into the interior of each of the multiple holes. One end of the bolt 4 is threaded with a nut 6 for fixing steel plate A 5. Steel plate B 7 is welded to one side of the upper surface of steel plate A 5. Steel plate A 5 and steel plate B 7 are made of 3mm thick steel plate by cutting, pressing, and drilling. The length is 150mm, the width is 50mm, and the thickness is 3mm. Steel inner support 8 is welded to one side of steel plate B 7.
[0023] A simple reinforcement tool is made using steel plate A (5), steel plate B (7), bolts (4), and steel internal bracing (8). Personnel can manually control the tool's position and adjust the tightness of the reinforcement. This tool is used to reinforce the lateral formwork of structural cantilever slabs, quickly reinforcing the lateral formwork to improve construction efficiency and ensure the quality of the concrete forming on the slab's side. It also connects to the steel keel 1 of the formwork support frame to reinforce the lateral formwork of the structural cantilever slab, providing stable reinforcement and easy assembly and disassembly.
[0024] The bottom end of the steel inner support 8 is welded to the other side of the upper surface of steel plate A 5. The diameter of the steel inner support 8 is 20mm. The steel inner support 8 supports steel plate A 5 and steel plate B 7, ensuring that steel plate B 7 deforms when supporting the lateral template.
[0025] The bottom end of the bolt 4 is provided with a nut 9, which is welded to the lower surface of the assembly plate 3.
[0026] The A steel plate 5 and the assembly plate 3 and the arc-shaped steel pipe 2 are connected by bolts 4 and nuts 6 to form a template reinforcement tool. Bolts 4 are welded to the bottom of the assembly plate 3 by nuts 9, which makes it easy to align and connect the assembly plate 3 and the A steel plate 5, thus improving the installation efficiency.
[0027] A timber 10 is attached to one side of the upper surface of the steel keel 1 of the template support frame. A template 11 is attached to the upper surface of the timber 10. A timber 12 is attached to the other side of the upper surface of the template 11. The timber 12 and the template 11 are laterally pressed together.
[0028] The template 11 is supported and kept stable by placing A timber 10 on the steel keel 1 of the template support frame, while B timber 12 and B steel plate 7 are used to push and reinforce the template 11 laterally, thereby achieving the stability of the template 11, reducing the leakage of concrete caused by template tilting during the pouring process, and increasing the number of times the template 11 can be reused.
[0029] One side of the B timber 12 is tightly abutted against the B steel plate 7. The inside of the arc-shaped steel pipe 2 is provided with anti-slip teeth 13. The anti-slip teeth 13 ensure the tightness of the template support frame steel keel 1 after the nut 6 is tightened, and prevent the slippage effect after fixing.
[0030] Specifically, during operation / use, this concrete structure cantilever slab side formwork reinforcement device allows for flexible adjustment of the reinforcement position of the side formwork. By loosening nut 6, the arc-shaped steel pipe 2 and steel plate A 5 can be moved flexibly on the steel keel 1 of the formwork support frame. After adjusting to the appropriate position, tightening nut 6, in conjunction with anti-slip teeth 13, fixes steel plate A 5 to the steel keel 1 of the formwork support frame. This enables efficient reinforcement of timber A 10 and timber B 12 during the construction of the cantilever slab, increasing the turnover rate of formwork 11 while ensuring the molding quality of the side concrete. This saves time on formwork 11 reinforcement, reduces the input of construction personnel, ensures the stability of the side formwork 11, and guarantees the molding quality of the side concrete of the cantilever slab. Thus, it achieves the goals of saving construction time, reducing project personnel costs, increasing the turnover rate of formwork 11, ensuring the stability of the side formwork, and guaranteeing the molding quality of the side concrete of the cantilever slab.
[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
