Description

  The present invention relates to a support device for supporting a load-bearing beam and a floor slab, which is used during construction work, and more particularly to a bracket extending a part of a vertical pipe in the support device and a support device using the bracket.

  During the construction of the building, it is necessary to install a supporting device composed of a large number of vertical and horizontal pipes on the ground. Make the top. The required support target position above the support device includes two parts: a load-bearing beam and a floor slab between the load-bearing beams. Since the bottom surface of the floor slab is higher than the bottom surface of the load-bearing beam, the height of the vertical tube that supports the load-bearing beam is smaller than the height of the vertical tube that supports the floor slab when the support device is installed in these two portions. To solve this problem, in many cases, higher assembly brackets are installed separately to provide floor slab support, which requires more human and material resources and lowers construction costs. To increase.

  To overcome the disadvantages of the prior art, the present invention aims to provide a height adjustable bracket connected to the longitudinal tube of a conventional support device to increase the height of the longitudinal tube.
