The Contraband-shaped transition 23 includes an outer riser 42, a horizontal web, and an inner riser 41. The L-shaped support 26 comprises a vertical plate 47 of the L-shaped support and a horizontal plate 27 of the L-shaped support, and the vertical section of the vertical plate 47 of the L-shaped support is a trapezoidal plate which is thin at the top and thick at the bottom. Triangular reinforcing ribs 25 are fixed to the vertical plate 47 of the L-shaped support and the horizontal plate 27 of the L-shaped support. The support may also be referred to as a support.
The horizontal plate 31 of the connecting base is fixed on a horizontal plate 33 of a second steel embedded part connected with built-in steel bars of a floor slab, at least two vertical screws 29 are fixed on the horizontal plate 31 of the connecting base, the horizontal plate 27 of the L-shaped supporting part is provided with first long through holes 28 which are equal to the vertical screws 29 in number, are also three and extend along the inner and outer directions, the first long through holes 28 penetrate through the vertical screws 29 in one-to-one correspondence, the horizontal plate 27 of the L-shaped supporting part is attached to the horizontal plate 31 of the connecting base and locked by a first nut 35, and a square gasket 34 can be sleeved on the vertical screws 29. The Contraband-shaped transition piece 23 has at least one circular through hole 24 for passing a first bolt 43, the at least one first bolt 43 passes through the circular through hole 24 and is screwed into a threaded hole 44 of a first steel embedded piece 22 connected with the built-in steel bar of the external wall panel, and the first bolt 43 can be sleeved with a circular washer 34. The riser 47 of the L-shaped support is provided with at least two second long through holes 36 extending along the height direction, the inner riser 41 of the Contraband-shaped transition is provided with third long through holes 40 which are equal to the second long through holes in number, are also two and extend along the length direction, at least two second bolts 37 correspondingly penetrate through the second long through holes 36 and the third long through holes 40 one by one, the inner riser 41 of the Contraband-shaped transition 23 is fastened with the riser 47 of the L-shaped support through respective second nuts 39, and the second bolts 37 can be sleeved with circular washers 38.
Contraband font transition 23's outer riser 42 can be narrower than interior riser 41, and the horizontal connecting plate who connects Contraband font transition 23's outer riser 42 and interior riser 41 is the trapezoidal board of interior length short outward, and the circular through-hole 24 of threading bolt usefulness can only establish one, and this structure is guaranteeing under the prerequisite condition of joint strength, support dynamics, firm in connection, saves the material cost of connection relatively.
The vertical cross-section of the risers of the L-shaped support of the upper connecting element 1 can also be trapezoidal, with a thinner upper part and a thicker lower part, but in the opposite direction to that shown in the figures, i.e. the root of the upper part is thinner and the downward edge is progressively thicker, the function of which is the same as that of the trapezoidal plates of the upper connecting element. Of course, the vertical cross-section of the vertical plate of the L-shaped support of the upper connecting member 1 may also be an equal-thickness steel plate, i.e., a rectangular plate having an equal dimension from the root to the edge, i.e., a flat vertical cross-section.
It will be understood that all the components, i.e. all the parts, of the above-described connecting elements, i.e. the upper and lower connecting elements 5, are made of steel, to name a few: the Contraband-shaped transition piece 23 is a steel Contraband-shaped transition piece, the L-shaped support 26 is a steel L-shaped support, the connecting base 30 is a steel connecting base, the bolt is a steel bolt, and the nut is a steel nut.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
