Description

Technical Field

[0001] This invention relates to tools for manually transporting steel formwork. Background Technology

[0002] Formwork is an indispensable temporary support structure in concrete construction. It must be fabricated according to design requirements to ensure that concrete structures and components are shaped in the specified positions and geometric dimensions, and to bear the self-weight of the formwork and external loads acting upon it. Commonly used formwork in building construction includes: wooden formwork, steel formwork, plastic formwork, and aluminum formwork. Steel formwork is widely used in various concrete structures, especially bridges, hydraulic structures, and high-rise buildings, due to its high strength, large combined rigidity, small deformation, good overall integrity, precise dimensions, high forming quality, high construction efficiency, and ability to be reused multiple times.

[0003] However, steel formwork also has a large weight, and its transportation and dismantling rely heavily on hoisting equipment. It cannot be operated manually alone. The installation, dismantling, and transportation of formwork all require the cooperation of lifting equipment, making it highly dependent on machinery. Construction is particularly difficult in situations such as small-section tunnels, small structures, multiple and scattered work areas, and poor access road conditions. When encountering poor road conditions and the transportation of scattered components, the method of manual pulling and carrying is often used, which is time-consuming, labor-intensive, and prone to safety accidents. Summary of the Invention

[0004] This invention addresses the problems of labor-intensive and safety concerns associated with manual transportation of steel templates. It provides a tool for manually transporting steel templates.

[0005] The technical solution for achieving the technical objective of this invention is: a tool for manually transporting steel formwork, comprising a portal frame with wheels installed on the bottom, and a traction rod with a front hook and a rear hook respectively installed at both ends on the crossbar of the portal frame, wherein the front hook and the rear hook suspend the steel formwork under the portal frame.

[0006] Furthermore, in the aforementioned tools for manually transporting steel formwork, handles for manual pulling are respectively provided at the front and rear ends of the traction rod.

[0007] Furthermore, in the aforementioned tools for manually transporting steel formwork: the portal frame is welded from steel pipes, and the traction rod is a steel pipe connected to the horizontal steel pipe of the portal frame by a channel steel connector.

[0008] Furthermore, in the aforementioned tools for manually transporting steel templates: the wheel is a single wheel with spokes, and a tire is also provided on the outer edge of the wheel.

[0009] Furthermore, in the aforementioned tools for manually transporting steel templates: the wheels are wooden wheels.

[0010] Furthermore, in the aforementioned tools for manually transporting steel templates: the wheels are swivel wheels.

[0011] In this invention, the device utilizes the lever principle for easy lifting; the entire device can be processed from existing waste materials on construction sites, requiring no additional investment and resulting in low cost; it reduces the use of hoisting equipment during temporary, small-scale, and fast-cycle steel formwork transportation.

[0012] Equipped with front and rear towing bars, it allows for multi-person collaborative transportation, greatly improving transportation safety, especially when going uphill or downhill, on rugged roads, or with heavy components.

[0013] The present invention will now be described in more detail with reference to the accompanying drawings and embodiments. Attached Figure Description

[0014] Appendix Figure 1 This is a schematic diagram of the tool used for manually transporting steel formwork in Embodiment 1 of the present invention. Detailed Implementation

[0015] This embodiment describes a tool for manually transporting steel formwork, such as... Figure 1As shown: A tool for manually transporting steel formwork includes a portal frame 1 with wheels 2 mounted on its bottom. A traction rod 5, with front hooks 3 and rear hooks 4 at both ends, is installed on the crossbar of the portal frame 1. The front hooks 3 and rear hooks 4 suspend the steel formwork below the portal frame 1. A horizontal steel pipe serving as a handle 6 is installed at the front and rear ends of the traction rod 5. In practice, the portal frame 1 is welded from steel pipes, and the traction rod 5 is also a steel pipe connected to the horizontal steel pipe of the portal frame 1 by channel steel connectors 7. The wheels 2 mounted on the bottom of the portal frame 1 can be single wheels with spokes 2-1 and tires 2-2 on the outer edge of the wheel. Alternatively, they can be wooden wheels made of round wooden planks. Rollers made of round wood can also be used, or omnidirectional wheel wheels. In this embodiment, the wheel 2 used is a single wheel similar to a bicycle wheel, which is lightweight, readily available, and generally used to transport steel formwork weighing around 200-400 kg. However, the service life is limited. In some other embodiments, wooden wheels can be selected, with a layer of rubber added to the outside of the wooden wheels. This makes the steel mold transport tool with wheels have a long service life and low cost. Of course, in many cases, casters can be installed under the vertical bar of the portal frame 1. This is suitable for transporting steel molds on relatively flat ground. In some other embodiments, the positions of the front hook 3 and the rear hook 4 can slide along the traction rod 5. This is suitable for handling steel molds of different sizes. In practice, some binding ropes or some long-handled hooks can be added to the front hook 3 and the rear hook 4 to facilitate the loading and unloading of steel molds. The traction rod 5 is generally installed on the top of the horizontal bar of the portal frame 1, basically in the middle of the horizontal bar of the portal frame 1, so that both sides are balanced. A channel steel connector 7 is used to fix the traction rod 5 to the middle of the horizontal bar of the portal frame 1.

[0016] The tool structure in this embodiment is simple, such as Figure 1 As shown: It is a simple vehicle-like frame, consisting of a metal pole portal frame 1 and two wheels. The metal pole portal frame 1 forms the frame structure, and the wheels 2 are mounted below via vertical bars on both sides of the portal frame 1. The overall design is simple, and it may be used for transporting steel formwork, showcasing a basic mechanical structure.

[0017] In this embodiment, the device adopts a gantry structure, utilizing the lever principle for convenient lifting and transportation. The main body of the gantry support 1 is made of φ48.3×3.6 steel pipes, which are connected by welding. Two hooks, a front hook 3 and a rear hook 4, are installed at the lower part of the device's traction rod 5 for hooking and lifting steel templates. Pull rods are installed at both ends for coordinated operation by multiple people. The traction rod 5 is reinforced and welded to the tire gantry crossbar using 50 channel steel. The tires are made of φ16 steel reinforcement rings encased in patterned steel plates, and the tire spokes are made of φ12 threaded steel.

[0018] The effects and benefits of this embodiment are as follows: The device utilizes the lever principle, which facilitates lifting; the entire device can be processed from existing waste materials on construction sites, requiring no additional investment and resulting in low cost; it reduces the use of hoisting equipment during temporary, small-scale, and fast-cycle steel formwork transportation; and the front and rear towing rods allow for multi-person collaborative transportation, greatly improving transportation safety, especially when working on slopes, rugged roads, or handling heavy components.
