【Specific embodiment】
The utility model will be further described below in conjunction with the accompanying drawings, but protection domain of the present utility model be not limited to
Lower described.
As shown in Figures 1 to 6, the light prefabricated shears ladder of configuration butterfly beam of the present utility model, including upper platform beam
1st, butterfly beam 2, upper prefabricated waist slab 3, lower floor's landing beam 4, under prefabricated waist slab 5；Upper prefabricated waist slab 3 and upper platform beam 1
Junction and under prefabricated waist slab 5 be connected by fixed-hinged support 6 with the junction of butterfly beam 2；Described upper prefabricated ladder
Section plate 3 and 2 junction of butterfly beam and under prefabricated waist slab 5 connected by slip hinged-support 7 with the junction of lower floor landing beam 4
Connect.The characteristics of light prefabricated shears ladder of configuration butterfly beam of the present utility model has lightweight, easy construction.
Two ends as preferred, described upper prefabricated waist slab 3 are provided with much at the two ends of prefabricated waist slab 5 with
In two bolts hole 10, it is provided with and bolt hole on described butterfly beam 2, on upper platform beam 1 and on lower floor's landing beam 4
10 corresponding pre-embedded bolts 9, can conveniently install fixation.
As preferred, fixed-hinged support 6 using bolt by upper prefabricated waist slab 3 and upper platform beam 1 and under prefabricated
Waist slab 5 is connected with butterfly beam 2, then pours into grouting material in cavity, finally blocks cavity mouth with cement mortar；Slip hinged-support
7 using bolt by upper prefabricated waist slab 3 and butterfly beam 2 and under prefabricated waist slab 5 be connected with lower floor landing beam 4, in cavity not
