Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a convenient template transfer cart for construction. Background Art

[0002] Formwork construction is widely used in the construction of highways and urban roads. Formwork is a temporary support structure, which is made according to the design requirements to ensure that the concrete structure and components form the required shape and size, maintain their correct position, and bear the weight of the building formwork and the external loads acting on it. The purpose of formwork construction is to ensure the quality and safety of concrete engineering, speed up the construction progress and reduce engineering costs.

[0003] In order to reduce resource waste and save costs, the formwork is generally designed to be recyclable and reusable. After the construction of one section is completed, the dismantled formwork will be transported to the next section for construction. During the transportation process, due to the heavy weight of the formwork, workers have to manually move and transport it, which is not only labor-intensive and inefficient, but also easy to cause damage to the formwork, which not only affects the quality of the concrete components, but also increases the construction cost. In view of this, some people have designed a construction formwork transfer device, and some construction formwork transfer devices have also been reported in public literature, for example, Chinese Patent: A Construction Formwork Transfer Device, Application Number: 202320088417.2, Application Date: 2023.01.31, Abstract: The utility model discloses a construction formwork transfer device, including a connecting rod, one side of the connecting rod is connected to a front frame, a steering mechanism is installed on the front frame, and one side of the front frame is connected to a connecting mechanism. The utility model discloses can adjust the overall length of the construction formwork transfer device by moving in the shaft sleeve and the fixed frame through the connecting rod, so as to adapt to construction formworks of different lengths. The trailer frame connected with the roller on one side of the front frame is connected with the external matching power vehicle equipment through the external connecting ring, so as to drive the construction formwork transfer device and the construction formwork to move. The steering is performed by the steering wheel in the front frame, so as to improve the working efficiency of the construction formwork transfer device, and avoid the problem of low construction formwork transfer efficiency caused by the inconvenience of adjusting the transfer device, the inability to adapt to formworks of different sizes, and the lack of special steering design when the existing construction formworks are transferred on the construction site.
