Detailed Description
in order to more clearly illustrate the technical solution of the present invention, the drawings used in the description will be briefly introduced, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and it is obvious for those skilled in the art that other embodiments can be obtained according to the drawings without inventive labor.
as shown in fig. 1 and 2:
The invention provides a novel balsawood-concrete floor system. Provides a new idea and method for connecting the wood beam and the concrete slab.
There are two or more wood beams 1, in this embodiment 3 wood beams 1.
The top surface of the wood beam 1 along the grain direction is provided with a pin groove 11, the pin groove 11 is positioned in the middle of the top surface of the wood beam 1, the depth of the pin groove 11 is half of the height of the steel plate 2 with the row holes 21, and the width of the pin groove 11 is slightly larger than the thickness of the steel plate 2. The diameter of the row holes 21 of the steel plate 2 is slightly larger than that of the steel bars 3.
The lower part of the steel plate 2 is embedded in the pin groove 11 and is fixedly connected with the wood beam 1 with an adhesive layer filled in the pin groove 11.
