Description

Technical Field

[0001] The utility model relates to the field of steel formwork, in particular to a steel formwork structure with high sealing performance. Background Art

[0002] In the existing steel formwork design, bolt holes are usually left on the four side walls, and two or more formworks are connected to each other through bolts. Although this design method is simple, the existence of bolt holes has become a weak link in the sealing between formworks. During the concrete pouring process, the slurry is likely to seep out from the bolt holes, resulting in slurry leakage, which not only affects the project quality but also increases the workload of later cleaning and repair.

[0003] Due to the gap existing in the bolt connection and the fact that the bolts themselves may fail due to loosening or damage, the connection stability between formworks is insufficient. When bearing the huge pressure during concrete pouring, the formworks are prone to deformation or displacement, affecting the forming quality of concrete. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a steel formwork structure with high sealing performance, and solve the following technical problems: how to improve the sealing performance between formworks and prevent slurry leakage during the concrete pouring process.

[0005] In order to solve the problems existing in the prior art, the technical scheme adopted by the utility model is as follows:

[0006] A steel formwork structure with high sealing performance includes a formwork body. There are two formwork bodies which are mutually attached to each other. On the inner walls around the formwork bodies, convex blocks are symmetrically and fixedly connected. Inside the convex blocks, inserting rods are fixedly connected. On one side between the formwork bodies, worm wheels are symmetrically arranged. On one side of each worm wheel, curved slideways are symmetrically opened. One ends of the two inserting rods corresponding to the worm wheels are respectively slidably connected inside the corresponding curved slideways. An embedding groove is opened at one end of the curved slideway. A rotating rod is fixedly connected to the center of the worm. A connecting seat is fixedly connected to the outer side of one end of the rotating rod. A worm is rotatably connected inside the connecting seat. The worm is meshed with the corresponding worm wheel.

[0007] Preferably, knobs are fixedly connected to both ends of the worm, so that it is convenient to drive the rotation of the worm by rotating the knobs, and then drive the movement of the worm wheel and the inserting rod.

[0008] Preferably, a U-shaped piece is rotatably connected to one side of the connecting seat through a hinge. The U-shaped piece is buckled on the outer side of the joint of the two formwork bodies. The addition of the U-shaped piece effectively prevents the relative movement between the formwork bodies, ensuring the overall stability and sealing performance of the formwork structure during the concrete pouring process and other processes.

[0009] Preferably, one end of the insertion rod is provided with a retaining piece, the curved slideway is arranged in a shape with a wider inner part and a narrower outer part, the retaining piece is slidably connected inside the curved slideway, and the retaining piece at one end of the insertion rod cooperates with the curved slideway with a wider inner part and a narrower outer part, ensuring that the insertion rod will not separate from the curved slideway during the sliding process.

[0010] Preferably, round holes are opened at the four corners of the surface of the plate body, facilitating the insertion of steel bars and enabling the high-sealing steel formwork structure to be more flexibly applied to various concrete structures requiring steel bar reinforcement.

[0011] Preferably, triangular pieces are symmetrically and fixedly connected to the peripheries of the inner walls of the plate body, enhancing the stability of the peripheries of the plate body and improving the stiffness and load-bearing capacity of the plate body.

[0012] Preferably, strip-shaped grooves are equidistantly opened on the outer side of the knob, providing a better grip and anti-slip performance.

[0013] Compared with the related art, the utility model has the following beneficial effects:

[0014] By canceling the bolt holes in the traditional steel formwork design and instead adopting the method of directly fitting two plate bodies, the structure significantly reduces the gaps between the formworks, thereby greatly improving the sealing performance, preventing the leakage of concrete during the pouring process, and contributing to the improvement of the project quality and construction efficiency.

[0015] This structure designs bumps and insertion rods on the peripheries of the inner walls of the plate body, and through the cooperation of the worm gear, worm, and curved slideway, realizes the tight fitting and small-scale adjustment between the plate bodies. At the same time, the U-shaped piece on the connecting seat further enhances the stability and reliability of the formwork structure, prevents the relative movement between the plate bodies, and ensures the overall stability of the formwork during use.

[0021] In order to make the purpose, technical solution and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0022] The high-sealing steel formwork structure has a formwork body 1;

[0023] As Figures 1 to 4 shown, there are two formwork bodies 1, and the two formwork bodies 1 are attached to each other. On the inner walls of the four sides of the formwork body 1, convex blocks 2 are symmetrically and fixedly connected. An insertion rod 3 is fixedly connected inside the convex block 2. On one side between the formwork bodies 1, worm wheels 4 are symmetrically arranged. On one side of each worm wheel 4, curved slideways 5 are symmetrically opened. One ends of two insertion rods 3 corresponding to the worm wheel 4 are respectively slidably connected inside the corresponding curved slideways 5. An embedding groove 6 is opened at one end of the curved slideway 5. A rotating rod 8 is fixedly connected to the center of the worm 7. A connecting seat 9 is fixedly connected to the outside of one end of the rotating rod 8. The worm 7 is rotatably connected inside the connecting seat 9, and the worm 7 is meshed with the corresponding worm wheel 4;

[0024] Different from the existing steel formwork design, the high-sealing steel formwork structure does not have bolt holes on the four side walls, but realizes the connection through the direct attachment of the two formwork bodies 1. This design significantly improves the sealing performance between the formworks and reduces the gaps generated by bolt connection;

[0025] During the process of the formwork bodies 1 being attached to each other, the convex blocks 2 on the inner walls of the four sides of the formwork body 1 and the insertion rods 3 inside them play a key role. When the two formwork bodies 1 are attached, the adjacent two insertion rods 3 will be inserted into the two symmetrically opened curved slideways 5 of the same worm wheel 4. This step ensures the correct alignment between the insertion rod 3 and the worm wheel 4 and lays a foundation for subsequent close attachment;

[0026] Next, by rotating the worm 7, the worm 7 starts to rotate and drives the meshed worm wheel 4 to rotate synchronously. The rotation of the worm wheel 4 further guides the curved slideway 5 thereon to rotate, thereby driving the insertion rod 3 inserted therein to slide along the curved slideway 5. During the sliding process, the insertion rods 3 can gradually approach, thereby reducing the distance between the two formwork bodies 1 and realizing closer and closer attachment.

[0027] As Figures 1 to 4 shown, the two ends of the worm 7 are fixedly connected with knobs 10, and the worm 7 is driven to rotate by rotating the knobs 10, making the adjustment more convenient.

[0028] As Figures 1 to 4As shown, one side of the connecting seat 9 is rotatably connected to a U-shaped piece 11 through a hinge. The U-shaped piece 11 is buckled on the outside of the joint where the two plate bodies 1 are in contact. To further enhance the stability and sealing performance of the formwork structure, the U-shaped piece 11 rotatably connected to one side of the connecting seat 9 through a hinge can be buckled on the outside of the joint where the two plate bodies 1 are in contact. The addition of the U-shaped piece 11 not only provides additional fixing force but also further prevents the relative movement between the plate bodies 1, ensuring the overall stability and sealing performance of the formwork structure.

[0029] As Figures 1 to 4 shown, a retaining piece 12 is provided at one end of the insertion rod 3. The curved slideway 5 is arranged in a shape with a wider inner width and a narrower outer width. The retaining piece 12 is slidably connected inside the curved slideway 5. Since the curved slideway 5 is designed in a shape with a wider inner width and a narrower outer width, and a retaining piece 12 is provided at one end of the insertion rod 3, after the insertion rod 3 is inserted into the curved slideway 5 through the insertion groove 6, the rotating worm gear 4 will guide the insertion rod 3 to slide towards the other end of the curved slideway 5. Through the cooperation of the retaining piece 12 and the curved slideway 5 with a wider inner width and a narrower outer width, the insertion rod 3 cannot be separated from the curved slideway 5. Only when the insertion rod 3 slides to the area of the insertion groove 6 can it be withdrawn from the curved slideway 5.

[0030] As Figures 1 to 4 shown, round holes 13 are provided at the four corners of the surface of the plate body 1, facilitating the insertion of steel bars through the round holes 13.

[0031] As Figures 1 to 4 shown, triangular pieces 14 are symmetrically and fixedly connected to the four surrounding sides of the inner wall of the plate body 1 to enhance the stability of the four surrounding sides of the plate body 1 through the triangular pieces 14.

[0032] As Figures 1 to 4 shown, strip-shaped grooves are equidistantly provided on the outside of the knob 10 to prevent slipping during rotation.

[0033] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
