Description

Technical Field

[0001] The utility model relates to a channel steel formwork, in particular to a channel steel formwork that can be quickly disassembled. Background Art

[0002] For the patent "A Channel Steel Formwork with a Built-in Support System" with the application number "202322480484.1", the support system is integrated with the formwork. This structure forms a whole. When a certain rod in the support system is bent and deformed due to impact, it will cause unstable support, and it is very inconvenient to replace the integral structure. In addition, the connection structure between the channel steel formworks in this device is very complex, which is not conducive to improving the assembly efficiency of the channel steel formworks. Summary of the Invention

[0003] The technical problem to be solved by the utility model is to provide a channel steel formwork that can be quickly disassembled, which can realize the integration of the splicing of the channel steel formwork and the installation of the support components, reduce the working procedures, ensure the reliability of the installation, and the support components can also be disassembled and replaced later.

[0004] To solve the above technical problem, the technical solution adopted by the utility model is:

[0005] A channel steel formwork that can be quickly disassembled includes a formwork body. On the inner sides of the left and right ends of the formwork body, perforated ear plates are fixed. The perforated ear plates at each end are distributed vertically. When adjacent formwork bodies are spliced, the first support component passes through the perforated ear plates and is locked.

[0006] The first support component includes upper and lower threaded sleeves. The left and right threads in each threaded sleeve have opposite helix directions. The left and right of each threaded sleeve are correspondingly threadedly connected with U-shaped screw rods. The other ends of the U-shaped screw rods pass through the corresponding perforated ear plates and are inserted into the positioning sleeves of the rotating shafts. When the threaded sleeves are rotated until the adjacent formwork bodies are tightly spliced, the other ends of the U-shaped screw rods are abutted against the bottom surfaces of the positioning sleeves. A second support component is installed on the rotating shaft, and the second support component supports the formwork body.

[0007] The second support component includes a connecting sleeve. The connecting sleeve is connected to the sleeve through a connecting rod. The pile column passes through the sleeve and is driven into the ground.

[0008] Perforated ear plates are welded at the middle section position on the inner side of the formwork body.

[0009] The utility model provides a channel steel formwork that can be quickly disassembled, having the following technical effects:

[0010] 1). By welding ear plates at both ends of the formwork body, the first support component is used for detachable installation of the formwork support components; at the same time, the splicing of the formwork body can also be realized, improving the assembly efficiency.

[0011] 2), By adopting a rotating shaft with a positioning sleeve, the first support component can be detachably installed, which is convenient for disassembling the formwork support component later, and is convenient for storage, transportation and replacement. Brief Description of the Drawings

[0018] As Figures 1-5 shown, a quickly detachable channel steel formwork includes a formwork body 1, and the formwork body 1 is a common channel steel with a height of 20 mm or 25 mm, which is selected according to the thickness of the road surface. Holed ear plates 2 are welded on the inner sides of the left and right ends of the formwork body 1, and the holed ear plates 2 at each end are distributed up and down. When adjacent formwork bodies 1 are spliced, the first support component 3 passes through the holed ear plates 2 and is locked. The first support component 3 can complete the splicing of adjacent formwork bodies 1, and at the same time, the formwork support component can be installed on the formwork body 1 to realize the support of the formwork body 1 later.

[0019] Specifically, as Figures 2-4 shown, the first support component 3 includes upper and lower thread sleeves 3.1, and the thread directions of the left and right in each thread sleeve 3.1 are opposite. A U-shaped screw rod 3.2 is threadedly connected to the left and right of each thread sleeve 3.1, and the other end of the U-shaped screw rod 3.2 passes through the corresponding holed ear plate 2. When the thread sleeve 3.1 is rotated, due to the opposite thread directions on both sides, the two U-shaped screw rods 3.2 can move relatively closer or relatively farther away. When the two U-shaped screw rods move relatively closer, the horizontal parts of the two U-shaped screw rods will squeeze the holed ear plate 2, causing the adjacent formwork bodies 1 to approach and fit tightly.

[0020] Meanwhile, positioning sleeves 3.4 are fixedly installed on the left and right of the upper and lower ends of the rotating shaft 3.3. The length of the rotating shaft 3.3 is less than the inner height of the template body 1, and the inner diameter of the positioning sleeve 3.4 is less than the end diameters of the two U-shaped screws. When the two U-shaped screws 3.2 can approach each other relatively, the ends of the two U-shaped screws 3.2 can be inserted into the positioning sleeve 3.4 of the rotating shaft 3.3. When two adjacent template bodies 1 are closely spliced, the U-shaped screw 3.2 just abuts against the inner bottom surface of the positioning sleeve 3.4, thereby realizing the installation of the template support assembly.

[0021] A second support assembly 3.5 is installed on the rotating shaft 3.3 in the template support assembly, and the second support assembly 3.5 supports the template body 1. The second support assembly 3.5 includes a connecting sleeve 3.5.1, which is sleeved on the rotating shaft 3.3 and can rotate relative to the rotating shaft 3.3. The connecting sleeve 3.5.1 is connected to a sleeve 3.5.3 through a connecting rod 3.5.2, and a pile column 3.5.4 passes through the sleeve 3.5.3 and is driven into the ground.

[0022] In addition, if the length of the template body 1 is relatively long, an ear plate 2 with holes can also be welded at a suitable position in the middle section of the inner side of the template body 1, and the template support assembly can be selectively installed, thereby improving the support strength.
