Description

Technical Field

[0001] This utility model relates to the field of roadbed engineering construction technology, and in particular to a mobile and portable steel formwork device for drainage ditch body. Background Technology

[0002] In highway construction, wooden formwork is a commonly used formwork method in the construction of concrete drainage ditches. However, this type of formwork has several significant drawbacks: First, the turnover rate of wooden formwork is quite low, typically exceeding five times. This means that in large-scale projects or those with long construction periods, the construction team has to frequently replace the formwork, causing construction costs to increase dramatically. Second, the installation and dismantling process of wooden formwork is extremely cumbersome and complex, with a significant amount of time consumed during the splicing process, which undoubtedly slows down the progress of the entire construction project. Third, the material properties of wooden formwork make it difficult to achieve a tight, seamless joint, which easily leads to grout leakage during concrete pouring. This not only results in unnecessary waste of raw materials but also inevitably causes defects such as honeycomb and pitting on the surface of the finished drainage ditch, severely affecting its appearance and quality. In addition, wooden formwork is relatively weak and is prone to deformation once it is subjected to the lateral pressure of concrete. This makes it difficult to accurately control the shape of the drainage ditch, often resulting in situations such as bending or twisting that do not meet design standards. Moreover, misalignment frequently occurs at the joints of the formwork, which seriously damages the regularity and aesthetics of the drainage ditch. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide a mobile and portable steel formwork device for drainage ditch body, which has a solid and stable structure, can be reused many times, has a long service life, is easy to move, reduces labor intensity and improves work efficiency during construction.

[0007] Furthermore, the caster is mounted on the lower end of the vertical screw.

[0008] Furthermore, the transverse support rod includes a central steel pipe and transverse screws fitted inside both ends of the central steel pipe. The central steel pipe has internal threads, and the transverse screws are threadedly connected to the central steel pipe and extend from the end of the central steel pipe.

Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0023] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0024] like Figures 1-7 As shown, a mobile and portable steel formwork device for drainage ditch bodies includes a steel frame with adjustable width and height. Side formwork plates 6 are installed on both sides of the steel frame, and casters 1 are provided at the bottom of the steel frame. In the drainage ditch body pouring process, steel formwork replaces traditional wooden formwork, solving the technical problems of high construction cost, weak formwork rigidity, poor appearance quality, and uneven lines associated with wooden formwork in building construction and highway engineering. This device allows for adjustment of the width and elevation of the side formwork plates by adjusting the width and height of the steel frame, thus adapting to drainage ditches of different structural dimensions. The casters at the bottom of the device facilitate movement, reducing labor intensity and improving work efficiency during construction. The steel structure provides good overall integrity, stability, high rigidity, high strength, high reusability, convenient maintenance, and resistance to deformation. Concrete drainage ditches formed using this device have good lines and appearance quality, ensuring higher overall quality.

[0025] In this embodiment, the steel frame includes four retractable vertical support rods 4 arranged in a rectangular pattern. A pair of retractable horizontal support rods 2 are connected between the two rear vertical support rods and between the two front vertical support rods. A pair of longitudinal support rods 5 are connected between the two left vertical support rods and between the two right vertical support rods. The steel frame has a grid-like shape, is structurally stable, and has high strength. Scaffolding boards can be laid on top of the steel frame to serve as a concrete pouring platform. The vertical support rods, horizontal support rods, and longitudinal support rods are assembled into the steel frame by welding.

[0026] In this embodiment, the vertical support rod 4 includes a vertical outer steel pipe and a vertical screw rod that are sleeved together. The vertical outer steel pipe has an internal thread, and the vertical screw rod is threadedly connected to the vertical outer steel pipe and extends from the lower end of the vertical outer steel pipe. By rotating the vertical screw rod, the extension length can be adjusted, thereby adjusting the height of the vertical support rod 4.

[0027] In this embodiment, the caster is mounted on the lower end of the vertical screw.

[0028] In this embodiment, the transverse support rod 2 includes a central steel pipe 201 and transverse screws 202 fitted inside both ends of the central steel pipe. The central steel pipe has internal threads, and the transverse screws are threadedly connected to the central steel pipe and extend from the ends of the central steel pipe. The threads of the transverse screws at both ends have opposite directions. By rotating the central steel pipe, the transverse screws at both ends can be retracted or extended, thereby adjusting the length of the transverse support rod. To facilitate the rotation of the central steel pipe using tools, nuts can be welded to the outside of the steel pipe.

[0029] In this embodiment, in order to facilitate the assembly and disassembly of the side mold steel plate, the end of the protruding end of the transverse screw is provided with a hanging groove 203, and the side mold steel plate is provided with a hanging hole 601 for hanging on the hanging groove.

[0030] In this embodiment, a locking collar 3 is fitted onto the transverse screw 202, allowing it to slide relative to the screw and fit onto the end of the intermediate steel pipe. The transverse screw has a groove 204 parallel to the axial direction. A protrusion 301 extends into the groove from the inner side of the locking collar. A limiting groove 205 is provided at the end of the intermediate steel pipe, and a limiting part 302 on the inner side of the locking collar matches the limiting groove. After the length of the transverse screw 202 is adjusted, sliding the locking collar 3 to fit onto the end of the intermediate steel pipe restricts its rotation.

[0031] In this embodiment, the caster is a swivel caster with a braking function.

[0032] During use, the device is placed in the excavated drainage ditch. Based on the width and height of the ditch on the construction drawings, the horizontal support rods 2 and vertical support rods 4 are adjusted, as are the distance and height between the two side formwork steel plates 6, thus aligning the side formwork steel plates to the design dimensions on the construction drawings. Then, the casters 1 are fixed in place, and scaffolding boards are laid on top of the steel frame as a construction platform for concrete pouring. Concrete is poured between the side formwork steel plates and the excavated drainage ditch walls to form the ditch body. Once the concrete strength of the ditch body on both sides reaches the design and specification requirements, the horizontal support rods 2 and vertical support rods 4 are loosened. The device is then manually pushed forward a distance to proceed to the next section of construction, making construction convenient.
