Description

Technical Field

[0001] The invention relates to a tool for manually transporting steel templates. Background Art

[0002] Building formwork is an indispensable temporary support structure during concrete construction. It must be manufactured according to design requirements to shape the concrete structure and components into the specified positions and geometric dimensions, and to withstand the weight of the building formwork and the external loads acting on it. The formwork commonly used in building structure construction mainly includes: wooden formwork, steel formwork, plastic formwork, aluminum formwork, etc.

[0003] Steel formwork is widely used in various concrete structures, especially bridges, hydraulic structures, high-rise buildings, etc., due to its high strength, large combined stiffness, small deformation, good formwork integrity, precise size, high forming quality, high construction efficiency and multiple recycling uses.

[0004] However, steel formwork is also heavy, requiring heavy reliance on lifting equipment for transportation and disassembly, making it impossible to operate manually. The installation, disassembly, and transportation of formwork require the coordination of lifting equipment and are highly mechanically dependent. Construction is particularly challenging in small-section tunnels, small structures, multiple and dispersed working areas, and poor access roads. Transporting scattered structures in poor road conditions often relies on manual labor, which is time-consuming, labor-intensive, and prone to accidents. Summary of the Invention

[0005] The invention aims to solve the problems of labor-consuming and safety-prone manual transportation of steel templates at the current stage. The sachet is a tool for manually transporting steel templates.

[0006] The technical solution for achieving the technical purpose of the present invention is: a tool for manually transporting steel formwork, comprising a door-shaped bracket with wheels installed underneath, a traction rod with front hooks and rear hooks at both ends respectively provided on the cross bar of the door-shaped bracket, and the front hooks and rear hooks hang the steel formwork under the door-shaped bracket.

[0007] Furthermore, in the above-mentioned tool for manually transporting steel formwork: handles for manual dragging are respectively provided at the front end and the rear end of the traction rod.

[0008] Furthermore, in the above-mentioned tool for manually transporting steel formwork: the gate-shaped bracket is formed by welding steel pipes, and the traction rod is a steel pipe connected to the horizontal steel pipe of the gate-shaped bracket by a channel steel connector.

[0009] Furthermore, in the above-mentioned tool for manually transporting steel formwork: the wheel is a single wheel with spokes, and a tire is also provided on the outer edge of the wheel.

[0010] Furthermore, in the above-mentioned tool for manually transporting steel formwork: the wheels are wooden wheels.

[0011] Furthermore, in the above-mentioned tool for manually transporting steel formwork: the wheels are universal wheels.

[0012] In the present invention, the device utilizes the lever principle to facilitate lifting; the entire device can be processed by recycling existing waste materials at the construction site, without additional investment and low cost; and reduces the use of lifting equipment during temporary, small-scale, fast-cycle steel formwork transportation.

[0013] The front and rear towing rods are set up, which allows multiple people to cooperate in transportation, greatly improving the safety of transportation, especially when going up and down slopes, on rugged roads, and transporting heavy components.

[0014] The present invention will be described in more detail below with reference to the accompanying drawings and embodiments. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] Attachment Figure 1 This is a schematic diagram of the tool for manually transporting steel formwork in Example 1 of the present invention. DETAILED DESCRIPTION

[0016] This embodiment is a tool for manually transporting steel templates, such as Figure 1The figure shows a tool for manually transporting steel formwork, comprising a gantry 1 with wheels 2 mounted underneath. A traction rod 5 with front and rear hooks 3 and 4 at each end is mounted on the crossbar of the gantry 1. The front and rear hooks 3 and 4 respectively suspend the steel formwork from the bottom of the gantry 1. The front and rear ends of the traction rod 5 are provided with horizontal steel pipes for manual pulling, serving as handles 6. In practice, the gantry 1 is constructed from welded steel pipes, and the traction rod 5 is also a steel pipe connected to the cross pipe of the gantry 1 via a channel steel connector 7. The wheel 2 mounted underneath the gantry 1 can be a single wheel with spokes 2-1 and a tire 2-2 on the outer rim, or a wooden wheel made of a round plank. Alternatively, a roller made of logs or a universal wheel can be used. In this embodiment, the wheel 2 used is a single wheel similar to a bicycle wheel. It is lightweight and readily available, and is generally used to transport steel formwork weighing approximately 200-400 kg. But the service life is limited. In some other embodiments, wooden wheels can be selected, and a layer of rubber can be added to the wooden wheels. The steel mold transport tool with wheels has a long service life and low cost. Of course, in many cases, universal wheels can be installed under the vertical rod of the gate-shaped support 1. This is applicable to transporting steel molds in places where the ground is relatively flat. In some other embodiments, the positions of the front hook 3 and the rear hook 4 can slide along the traction rod 5. Like this, it can be suitable for carrying steel molds of different models. In practice, some binding ropes or some long hooks can be added to the front hook 3 and the rear hook 4 to facilitate the movement of the steel mold. The traction rod 5 is generally installed above the crossbar of the gate-shaped support 1, basically in the middle of the crossbar of the gate-shaped support 1, so that both sides are balanced. A channel steel connector 7 is utilized to fix the traction rod 5 to the middle of the crossbar of the gate-shaped support 1.

[0017] The tool structure of this embodiment is simple. Figure 1 As shown: It resembles a simple vehicle frame, consisting of a metal rod portal bracket 1 and two wheels. The metal rod portal bracket 1 forms the frame structure, and the wheels 2 are mounted below via vertical rods on both sides of the portal bracket 1. The overall shape is simple, possibly used for transporting steel formwork, and it shows the basic mechanical structure.

[0018] In this embodiment, the device utilizes a gantry structure, leveraging the principle of leverage to facilitate lifting and transportation. The main body of the gantry support 1 is fabricated from φ48.3×3.6 steel pipes, which are welded together. Two hooks are located at the front and rear of the lower portion of the device's drawbar 5, a front hook 3 and a rear hook 4, for hooking and lifting the steel formwork. Drag rods are located at both ends to facilitate coordinated operation by multiple personnel. The drawbar 5 is reinforced and welded to the tire gantry crossbar using 50 channel steel. The tires utilize φ16 steel hoops encased in patterned steel plates, and the tire spokes are fabricated from φ12 threaded steel.

[0019] The effects and benefits of this embodiment are as follows: the device utilizes the lever principle to facilitate lifting; the entire device can be processed by recycling existing waste materials at the construction site, without additional investment and low cost; the use of lifting equipment during temporary, small-scale, and fast-cycle steel formwork transportation is reduced; front and rear towing rods are set, and multiple people can cooperate in transportation, which greatly improves the safety of transportation, especially when going up and down slopes, rugged roads, and heavy components.
