Description

Technical Field

[0001] The utility model relates to the field of steel formwork, in particular to a spliced cylindrical steel formwork. Background Art

[0002] After the existing spliced cylindrical steel formwork is assembled, especially before pouring concrete, a leveling operation is often required to ensure the verticality and horizontality of the formwork. However, this leveling process usually relies on manual use of tools such as crowbars, which is not only complex in operation but also laborious and time-consuming.

[0003] Moreover, when using a crowbar for leveling, it needs to be inserted under the steel formwork, which not only increases the operation difficulty but also may cause damage to the edge of the formwork, affecting the pouring quality. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a spliced cylindrical steel formwork, and solve the following technical problems: how to simplify and optimize the leveling process and how to improve the stability of the formwork.

[0005] To solve the problems existing in the prior art, the technical solution adopted by the utility model is as follows:

[0006] A spliced cylindrical steel formwork includes a curved steel plate, vertical ribs and side strips. Vertical ribs are fixedly connected to the outer side of the curved steel plate at equal intervals. Side strips are provided on both sides of the curved steel plate. Bolt holes are provided on the surface of the side strips at equal intervals. Fixed pieces are symmetrically provided on one side of the side strips. A curved rod is fixedly connected between the fixed pieces at the same level on both side strips of the curved steel plate on both sides. Reinforcing ribs are provided between the curved rods. Both ends of the reinforcing ribs are fixedly connected with U-shaped buckles. The U-shaped buckles are sleeved on the outer sides of the corresponding curved rods. A pressing piece is slidably connected to the outer side of the U-shaped buckle. Nuts are threadedly connected to the outer sides of both ends of the U-shaped buckle. Lever bars are fixedly connected to the opposite sides between the U-shaped buckles.

[0007] Preferably, the lever bar is in a curved and inclined shape, so that the lever bar can provide a stable supporting force when it is turned over and propped on the ground.

[0008] Preferably, spherical blocks are fixedly connected to the ends of the lever bars. The round shape of the spherical blocks makes the adjustment of the formwork smoother and not easily stuck.

[0009] Preferably, the middle part of the pressing piece is in an arched shape, and the arched radian fits the curved rod, ensuring the stability of the U-shaped buckle on the curved rod and preventing loosening or falling off during use.

[0010] Preferably, supporting pieces are fixedly connected to the outer side of the curved rod at equal intervals. The supporting pieces are fixedly connected to the corresponding vertical ribs. The supporting pieces strengthen the connection between the curved rod and the vertical rib, forming a stable supporting network.

[0011] Preferably, triangular plates are equidistantly arranged at the top and bottom of the curved steel plate to enhance the stability of the formwork in the vertical direction.

[0012] Preferably, protective sheaths are symmetrically sleeved outside the reinforcing ribs. While protecting the corresponding areas of the reinforcing ribs, it also makes it more comfortable to hold the reinforcing ribs.

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

[0014] 1. In the utility model, by removing the U-shaped buckle at one end of the reinforcing rib and loosening the nut at the other end, the construction worker can easily hold the removed end of the reinforcing rib. Using the rotation of the U-shaped buckle outside the curved rod as a fulcrum, the lever principle is used to make the lever flip and support the ground, so as to level the steel formwork. By adjusting the position of the strip-shaped reinforcing rib, the leveling area can be accurately controlled to meet the requirements under different construction conditions. This convenient leveling method not only improves the construction efficiency but also reduces the labor intensity of the construction workers.

[0015] 2. The combined design of the curved rod and the support piece, and the connection of the reinforcing ribs between the curved rods through the U-shaped buckle enhance the stability and strength of the formwork structure. This strengthened connection mechanism enables the formwork to maintain good shape stability when bearing the concrete pouring pressure, reducing the risk of deformation and overturning.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] In order to make the purpose, technical solutions and advantages of the utility model clearer, the following further describes the utility model in detail with reference to the drawings and embodiments.

[0021] The spliced cylindrical steel formwork has a curved steel plate 1, vertical ribs 2 and side strips 3;

[0022] Such as Figures 1 to 3As shown in the figure, vertical ribs 2 are fixedly connected at equal intervals on the outer side of the curved steel plate 1. Side strips 3 are provided on both sides of the curved steel plate 1. Bolt holes 31 are provided at equal intervals on the surface of the side strips 3. Fixed pieces 32 are symmetrically provided on one side of the side strips 3. A curved rod 4 is fixedly connected between the fixed pieces 32 at the same level on both sides of the curved steel plate 1. Reinforcing ribs 5 are provided between the curved rods 4. Both ends of the reinforcing ribs 5 are fixedly connected with U-shaped buckles 6. The U-shaped buckles 6 are sleeved on the outer sides of the corresponding curved rods 4. A pressing piece 7 is slidably connected to the outer side of the U-shaped buckle 6. Nuts 8 are threadedly connected to the outer sides of both ends of the U-shaped buckle 6. Lever rods 9 are fixedly connected to the opposite sides between the U-shaped buckles 6;

[0023] The steel formwork is mainly composed of the curved steel plates 1, which can be spliced with each other and are tightly connected by the bolt holes 31 on the side strips 3 and fixing parts, thus forming a complete cylindrical inner cavity. The curved rods 4 span between the side strips 3 on both sides of the curved steel plates 1 and are connected through the fixed pieces 32, enhancing the strength and stiffness of the upper and lower ends of the steel formwork;

[0024] The reinforcing ribs 5 are connected between the curved rods 4 through the U-shaped buckles 6, which not only enhance the connection strength between the curved rods 4 but also endow the formwork structure with a certain degree of flexibility. When it is necessary to adjust the flatness of the bottom of the formwork, the U-shaped buckle 6 at one end of the reinforcing rib 5 can be removed, the nut 8 at the other end can be loosened, and then the removed end of the reinforcing rib 5 can be held. With the rotation of the U-shaped buckle 6 on the outer side of the curved rod 4 as the fulcrum, the lever principle is used to make the lever rod 9 flip and support the ground. In this way, the corresponding part of the bottom of the steel formwork will be slightly lifted, facilitating precise leveling operations. By adjusting the position of the strip-shaped reinforcing rib 5, the leveling area can be flexibly controlled to meet different construction requirements.

[0025] As Figures 1 to 3 shown, the lever rod 9 is bent and inclined, so that the lever rod 9 can more effectively support the bottom of the formwork when flipping and supporting the ground.

[0026] As Figures 1 to 3 shown, ball blocks 91 are fixedly connected to the ends of the lever rods 9. The ball blocks 91 provide good stability and grip when supporting the ground, and at the same time reduce the damage to the ground.

[0027] As Figures 1 to 3 shown, the middle part of the pressing piece 7 is arched, and the arched radian fits the curved rod 4. The arched design of the pressing piece 7 can closely fit the outer side of the curved rod 4. Through the sliding connection and the fastening effect of the nut 8, the pressing and fixing of the U-shaped buckle 6 are realized, ensuring the stability of the U-shaped buckle 6 on the curved rod 4 and preventing loosening or falling off during use.

[0028] As Figures 1 to 3As shown, support pieces 10 are fixedly connected at equal intervals on the outer side of the curved rod 4. The support pieces 10 are fixedly connected to the corresponding vertical ribs 2. The support pieces 10 fixedly arranged at equal intervals on the outer side of the curved rod 4 further tightly connect the curved rod 4 and the vertical ribs 2, forming a stable support system that effectively resists the lateral pressure generated during the concrete pouring process.

[0029] As Figures 1 to 3 shown, triangular plates 11 are provided at equal intervals at the top and bottom of the curved steel plate 1. The triangular plates 11 play an additional role in stable support.

[0030] As Figures 1 to 3 shown, sheaths 12 are symmetrically sleeved on the outer side of the reinforcing ribs 5 to protect the reinforcing ribs 5 from being eroded and damaged by the external environment, such as corrosion, wear, etc. At the same time, the sheaths 12 can also provide a certain buffering effect to reduce the stress concentration phenomenon of the reinforcing ribs 5 when they are subjected to impact or vibration. Secondly, the sheaths 12 can also make it more comfortable to hold the reinforcing ribs 5.

[0031] 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 principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
