Adjustable steel girder support device and system

Abstract

The invention discloses an adjustable steel girder support device and system; the support device comprises an upper beam, a lower beam, and a support adjusting bolt; the support adjusting bolt is threaded with a support nut; a support bar is rotatably connected on two ends of the upper beam; the distance between the support bar rotary point and the end portion is bigger than that between the support nut and the lower beam top surface; when the support nut height needs to be adjusted, the upper beam is pulled up, the support bars on two ends are rotated, so the long edge of the support bar is in a vertical state and can support the pulled upper beam, and the support nut is rotated and adjusted in positions; in operation, the upper beam does not need to be pulled at all time, so the adjusting operation can be easier and more convenient; the adjustable steel girder support devices can be connected via a shear-fork type structure so as to form the support system, thus ensuring the distanceuniformity between each adjustable steel girder support device; the adjustable steel girder support device is good and stable in support effect.

Description

technical field [0001] The present invention relates to a building construction device, more specifically, it relates to an adjustable steel beam support device and system. Background technique [0002] With the advancement of science and technology and the development of the construction industry, a variety of composite materials and tools that can not only ensure the quality of the project but also improve the construction efficiency have been gradually developed, such as laminated floor slabs, which are a combination of prefabricated and cast-in-place concrete. Better structural form, laminated slabs are the only important components for assembling monolithic buildings, and they are used in large quantities. In larger bays, cast-in-place slabs are often used to connect the laminated slabs. In the process of specific construction, it is necessary to Casting strips for support. [0003] For example, the Chinese patent with the announcement number 205857696U discloses an ad...

Problems solved by technology

[0003] For example, the Chinese patent with the announcement number 205857696U discloses an adjustable steel beam support device and system, which includes an upper beam and a lower beam, and the upper beam and the lower beam are connected by support adjustment bolts, the upper beam can be adjusted up and down, and the support adjustment The bolts are threaded to connect the support nuts supporting the upper beam, and then the upper beam is supported by setting the second corrugation and the film-coated board; but in the process of specific adjustment, the upper beam needs to be moved up first and then dragged and then supported by rotation After the nuts have adjusted the support height, place the upper beam on the support nuts. It is inconvenient to operate due to dragging the upper beam.
