Technical Field

[0001] This utility model relates to the field of building formwork technology, and in particular to a quick-installation formwork for construction. Background Technology

[0002] In the field of building construction, formwork engineering is an important part of concrete structure construction. Traditional building formwork is usually made of wood or steel. The installation process requires a large number of bolts, nails and other connectors. Not only is the installation process cumbersome and consumes a lot of manpower and time, but it also requires high technical skills from construction workers and has low installation efficiency.

[0003] Meanwhile, the fixed height and size of traditional formwork make it difficult to adapt to the needs of different building components and construction scenarios. When encountering components with special sizes or heights, it is often necessary to customize the formwork, which increases construction costs and time.

[0004] In addition, traditional formwork connection methods are prone to problems such as loosening of the connection points and deformation of the formwork during the concrete pouring process, which affects the molding quality of concrete components and may even cause safety accidents.

[0005] With the rapid development of the construction industry, the requirements for construction efficiency, project quality and cost control are getting higher and higher. There is an urgent need for a new type of building formwork that can be quickly installed, flexibly adjusted, structurally stable and low cost to meet the diversified needs of modern construction. This quick-installation formwork for construction is developed and designed based on this background. Utility Model Content

[0006] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a quick-installation template for construction that can solve the above-mentioned problems.

The use of terms like "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the quantity or sequence of the indicated technical features.

[0031] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0032] Please see Figure 1-4 This utility model provides a technical solution: a quick-installation template for construction, including a base 1, a sleeve 2 fixedly connected to the base 1, an inner rod 3 slidably connected inside the sleeve 2, and through holes 4 on both the inner rod 3 and the sleeve 2, with a round pin 5 snapped into the through hole 4;

[0033] The inner rod 3 is provided with a support plate 6 at the top. The support plate 6 is L-shaped and is threaded with an internal hex bolt 7. The support plate 6 is fixedly connected to the top of the inner rod 3 by the internal hex bolt 7. Threaded rods 8 are fixedly connected to both sides of the support plate 6. The threaded rods 8 are L-shaped and are threaded with positive and negative thread tubes 9. The distance between the support plates 6 can be adjusted by rotating the positive and negative thread tubes 9.

[0034] A template 10 is snapped into the support plate 6. One side of the template 10 has a tenon 11 and a mortise block 12 is fixedly connected to the other side. The template 10 is spliced ​​together by the tenon 11 and the mortise block 12. After splicing, one side of the template 10 is provided with a protruding plate 13 that fits into the tenon 11 of the template 10, and one side is provided with a concave plate 14 that fits into the mortise block 12 of the template 10, thereby connecting and fixing the templates 10 on both sides. A reinforcing plate 15 is snapped into the outside of the template 10 and the protruding plate 13. A reinforcing plate 15 is also snapped into the outside of the template 10 and the concave plate 14. The reinforcing plate 15 is L-shaped.

[0035] Working principle: During installation, the base 1 is first placed at the designated construction position as a basic support. According to the required construction height, the inner rod 3 is pulled up and down to adjust the height within the sleeve 2. When the inner rod 3 and the through hole 4 on the sleeve 2 are aligned, the round pin 5 is inserted into the through hole 4 to fix the height of the inner rod 3, thereby determining the reference height for the installation of the template 10.

[0036] Next, the L-shaped support plate 6 is installed on the top of the inner rod 3 using the hex socket head cap screw 7. According to the width of the template 10, the positive and negative thread tube 9 is rotated. Since the threaded rods 8 on both sides are L-shaped and threaded to the positive and negative thread tube 9, the rotation of the positive and negative thread tube 9 will drive the threaded rods 8 on both sides to move towards or away from each other, thereby adjusting the distance between the two support plates 6 to fit the size of the template 10.

[0037] Then, the template 10 is snapped into the support plate 6 and spliced ​​by the tenon 11 on one side of the template 10 and the mortise 12 on the other side. After splicing, on both sides of the adjacent template 10, the protruding plate 13 is fitted with the tenon 11 of the template 10 and the concave plate 14 is fitted with the mortise 12 of the template 10, thus completing the initial connection and fixation of the templates 10 on both sides.

[0038] Finally, L-shaped reinforcing plates 15 are snapped onto the outside of the template 10 and the convex plate 13, and onto the outside of the template 10 and the concave plate 14, respectively, to further enhance the stability of the template 10 connection and prevent displacement, deformation and other situations during concrete pouring, thus completing the entire installation process of the template 10.

[0039] During disassembly, first remove the reinforcing plate 15, then separate the connection between the convex plate 13, the concave plate 14 and the template 10, take the spliced ​​template 10 out of the support plate 6, reduce the spacing of the support plate 6 by rotating the positive and negative threaded tube 9, unscrew the internal hex bolt 7 to remove the support plate 6, pull out the round pin 5, and put the inner rod 3 into the sleeve 2 to complete the disassembly and storage of the template 10.

[0040] By sliding the inner rod 3 within the sleeve 2 and positioning the round pin 5, the installation height of the template 10 can be flexibly adjusted within a certain range, which can adapt to the construction needs of different floor heights and different building components. There is no need to customize the template 10 separately for a specific height, which improves the versatility and scope of use of the template 10.

[0041] The template 10 adopts the splicing method of mortise and tenon 11 and mortise block 12, and is equipped with convex plate 13, concave plate 14 and reinforcing plate 15. The installation process is simple and convenient, without complicated operation and professional tools. Construction personnel can quickly complete the splicing and fixing of the template 10. Compared with the traditional template 10 installation method, it greatly shortens the construction time and improves the construction efficiency.

[0042] By utilizing the cooperation of the positive and negative threaded tube 9 and the threaded rod 8, the distance between the support plates 6 can be precisely adjusted, which can adapt to templates 10 of different widths. Whether it is a standard size template 10 or a specially customized template 10, it can be installed stably to meet the needs of diverse construction scenarios.

[0043] The support plate 6, threaded rod 8, and positive and negative threaded tube 9 constitute a stable support and adjustment structure. The convex plate 13, concave plate 14 and reinforcing plate 15 strengthen the connection between the template 10. During the concrete pouring process, it can effectively resist lateral pressure, prevent the template 10 from deforming, bulging and other problems, and ensure construction safety and the forming quality of concrete components.

[0044] The template 10 is easy to disassemble, and each component can be quickly separated. After disassembly, the inner rod 3 can be retracted into the sleeve 2, reducing the overall volume, making it easy to store and transport, reducing storage space occupation and transportation costs. At the same time, the template 10 and its components have a simple structure, are not easily damaged, and can be reused multiple times, reducing construction costs.

[0045] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
