Description

Technical Field

[0001] This utility model belongs to the field of building steel formwork technology, and in particular relates to a wedge-shaped fastening combined steel formwork for construction. Background Technology

[0002] In building construction, wedge-shaped fastening combined steel formwork adopts a wedge structure design. Through wedge-shaped locking parts, formwork units are quickly and accurately spliced ​​and fixed. Utilizing the wedge self-locking principle, high-strength locking can be achieved without complicated tools, resulting in tight splicing, effectively preventing grout leakage and misalignment, and improving the quality of concrete molding.

[0003] When installing wedge-shaped fastening combined steel formwork, back ribs need to be assembled on the back, which makes it difficult to flexibly adapt to the height requirements of different working scenarios and makes it impossible to directly achieve locking between the wedge plates and the back ribs. Therefore, we need to design a wedge-shaped fastening combined steel formwork for construction, an adjustable height boltless wedge-locking construction steel formwork, which can be quickly assembled and disassembled without bolts, simplifying the process and improving efficiency. The height adjustment is flexible and adaptable to different construction scenarios. It can accurately control the position of the formwork, and the wedge locking is stable and reliable, with strong resistance to lateral pressure, ensuring the quality of concrete molding and contributing to high-quality construction.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A wedge-shaped fastening combined steel formwork for construction includes a steel formwork. Two symmetrical template back ribs 1 are welded to the left and right sides of the steel formwork. Two symmetrical template back ribs 2 are engaged with the surfaces of the two template back ribs 1. Wedge plates are locked to both ends of the template back ribs 1 and 2. The template back ribs 1 and 2 are fastened to the template back ribs 2 through the wedge plates. A bottom plate is provided on both the front and rear sides of the steel formwork. The bottom plate is welded to the ground. A column is fixedly connected to the central axis at the top of the bottom plate. Horizontal support rods are fixedly connected to the central axis on both sides of the column through steel plates. Four fixing seats are fixedly connected to the left and right sides of the side fixing column through bolts. A connecting rod is fixedly connected to the opposite side of two fixing seats.

[0013] In the following description, embodiments of the wedge-shaped fastening combined steel formwork for construction according to the present invention will be described with reference to the accompanying drawings.

[0014] Figure 1-4 This invention illustrates an embodiment of a wedge-shaped fastening combined steel formwork for construction, comprising a steel formwork 1. Two symmetrical template back ribs 2 are welded to the left and right sides of the steel formwork 1. Two symmetrical template back ribs 3 are engaged with the surfaces of the two template back ribs 2. Wedge plates 4 are locked to both ends of the template back ribs 1 and 2. The template back ribs 1 and 2 are fastened together via the wedge plates 4. A lower base plate 5 is provided on both the front and rear sides of the steel formwork 1, welded to the ground. A column 6 is fixedly connected to the central axis of the top of the lower base plate 5. Horizontal support rods 8 are fixedly connected to the central axes of the left and right sides of the column 6 via steel plates. Fixed columns 7 are welded to the left and right sides of the top of the lower base plate 5. The two opposing sides of the two fixed columns 7 are fixedly connected to the two horizontal support rods 8. The horizontal support rods 8 serve as transverse back ribs, cooperating with the template back ribs 1 and 2. It can strengthen the stability of the connection structure at the template back rib 12, disperse the lateral pressure, prevent the template back rib 12 from deforming and loosening due to concentrated force, and ensure the overall rigidity of the template back rib 12 side. The horizontal support rod 8 is provided with diagonal rods 9 on both the upper and lower sides. The column 6 is fixedly connected to the four diagonal rods 9 by steel plates. The four diagonal rods 9 are fixedly connected to the two side fixed columns 7. Two symmetrical reinforcing rods 10 are provided at the top of the two upper horizontal support rods 8. The two reinforcing rods 10 are fixedly connected to the top of the side fixed columns 7. Four fixing seats 11 are fixedly connected to the left and right sides of the side fixed columns 7 by bolts. A connecting rod 12 is fixedly connected to the opposite side of the two fixing seats 11. A connecting seat 13 is fixedly connected to the end of the connecting rod 12 away from the fixing seat 11. The connecting seat 13 is fixedly connected to the template back rib 12 by bolts. The shape of the horizontal support rod 8, diagonal rods 9 and reinforcing rods 10 is rectangular.

[0015] Working Principle: During construction, the lower base plate 5 is first welded and fixed to the ground, serving as the foundation support for the entire template system. The uprights 6 are vertically installed at the top center of the lower base plate 5, providing vertical support for the template 1 and the back support structure. The side fixing columns 7 are symmetrically arranged on both sides of the top of the lower base plate 5, forming a stable vertical support frame together with the uprights 6. After the template 1 is hoisted into place, the template back supports 2 welded to its left and right sides serve as the main lateral load-bearing components. Together with the template back supports 3 engaged on its surface, they form a multi-layered lateral support structure. The horizontal support rods 8, diagonal rods 9, and reinforcing rods 10 are connected to the uprights 6 and side fixing columns 7 via steel plates. The horizontal support rods 8 enhance lateral stiffness, the diagonal rods 9 utilize a triangular stabilizing structure to disperse lateral pressure, and the reinforcing rods 10 further improve the stability of the top structure. These three components work together to provide multi-dimensional support for the template back supports. The support enhances the overall load-bearing capacity. The fixing seat 11 is installed on the left and right sides of the side fixing column 7 by bolts. The connecting rod 12 connects to the fixing seat 11 and transmits the force to the connecting seat 13. The connecting seat 13 is fixed to the template back rib 1 2 by bolts, realizing the locking and fixing of the template back rib. At the same time, thanks to the height adaptability of the side fixing column 7 and the column 6, the height of the template system can be flexibly adjusted through the prefabricated installation holes and the locking adjustment of the template back rib 1 2 and the template back rib 2 3. Finally, the wedge plate 4 clamps the two ends of the template back rib 1 2 and the template back rib 2 3. Using the wedge self-locking principle, high-strength locking can be achieved without bolts, making the template joint tight, effectively resisting the side pressure of concrete, preventing grout leakage and misalignment, and ensuring the quality of concrete molding. The entire system achieves the construction effect of boltless quick assembly and disassembly, flexible height adjustment, and stable and reliable locking through the synergy of various components.

[0016] In summary, this wedge-shaped fastening combined steel formwork for construction, through the coordinated use of the fixing seat 11, connecting rod 12, and connecting seat 13, allows the two connecting seats 13 to fix the two template back ribs 1-2, and the two template back ribs 2-3 to be machined and clamped onto the surfaces of the two template back ribs 1-2. This then allows the wedge plate 4 to clamp the ends of the template back ribs 1-2 and 2-3, and finally locks and fixes the template back ribs 1-2 and 2-3. This achieves adjustable height, boltless wedge-shaped locking construction steel formwork, enabling quick assembly and disassembly without bolts, simplifying the process, improving efficiency, providing flexible height adjustment, stable and reliable wedge locking, strong resistance to lateral pressure, ensuring concrete molding quality, and contributing to high-quality construction.
