Description

Technical Field

[0001] The invention relates to the technical field of construction template accessories, and in particular to an adjustable connecting device for a curved beam template. Background Art

[0002] In the field of building construction, curved beams are increasingly used. Curved beams not only add unique aesthetic effects to buildings, but also provide better mechanical properties in the structure.

[0003] The curved beam adopts the construction method of cast-in-place concrete. Usually, the curved beam template is roughly bent into an arc shape along the required arc surface, and then concrete is poured directly on the upper part to form an arc structure similar to the required arc beam. After that, it is corrected into the required arc beam template through plastering or hammering. The existing Chinese invention patent with announcement number CN106382004B discloses an adjustable connection device for a curved beam formwork, including a threaded fixing sleeve with an internal thread, a screw with an external thread, a smooth fixing sleeve, and a guide rod. A fixing rod is provided between the threaded fixing sleeve and the smooth fixing sleeve, a limiting rod is provided between the screw and the guide rod, and one end of the limiting rod is fixedly connected to the guide rod, and the other end is provided with a limiting ring. A flange is provided on the screw, and the screw passes through the limiting ring and is threadedly connected to the threaded fixing sleeve. An operating part is provided on the screw, a support a is provided on the smooth fixing sleeve, a support b is provided on the guide rod, and connecting holes are provided on both the support a and the support b. The curvature of the curved beam formwork can be adjusted, and the curvature can be kept stable during construction.

[0004] The above-mentioned device bends the curved beam template by applying force to both ends of the curved beam template. It is suitable for shorter curved beam templates. The common curved beam radius is 1-10 meters. The radius of the curved beam in large buildings may exceed 10 meters, such as large gymnasiums, airport terminals, etc. When bending large curved beam templates, the required device specifications are also large, which is not convenient for operation. The bent curved beam template is prone to bounce up and fall off under the action of elastic force, causing certain safety risks to surrounding operators. Summary of the invention

[0028] Working principle:

[0029] The movable sleeve 9 is driven to slide along the top rod 8 by the electric telescopic rod 10, and the elastic adjustment plate 11 is driven to bend by the connecting rod 12, so as to adjust the curvature of the elastic adjustment plate 11, so that the elastic adjustment plate 11 is adjusted to a specified curvature, and the rotating block 13 is rotated so that the spherical surface of the top rod 8 abuts against the bottom of the elastic adjustment plate 11, providing support for the middle part of the elastic adjustment plate 11;

[0030] Then, the curved beam template is placed between the vertical plates 5 on both sides and above the elastic adjustment plate 11, and a force is applied downward to bend the curved beam template so that the curved beam template fits the elastic adjustment plate 11, so that the curved beam template can be in a specified curvature;
