First notch, the second notch, are equipped with crossbeam between the first through hole, the second through hole, the crossbeam is through at the first notch,
Two notches.
Pass through above-mentioned technical proposal, only need first to open first through hole, the second through hole on the wallboard of both sides when crossbeam is installed,
Afterwards again by transverse slat from first through hole through in the second through hole, it is not necessary to crossbeam is lifted to fixation from staircase boards, just
In installation.
Preferably, support column is provided between the crossbeam and ground.
Pass through above-mentioned technical proposal, support column can ensure the stability of crossbeam, improve the support effect of crossbeam.
Preferably, state crossbeam and be provided with mounting hole, support column one end is located in mounting hole.
Pass through above-mentioned technical proposal, support column one end are located at the locating effect that support column can be improved in mounting hole.
Preferably, the support column is provided with extension, and extension is provided with the fixture mutually fixed with crossbeam.
Pass through above-mentioned technical proposal, extension is set on support column and fixed by fixture and crossbeam, can be improved
Support column is located at the fixed effect of crossbeam one end.
Preferably, one end that the support column is located in mounting hole is provided with circular arc chamfering.
Pass through above-mentioned technical proposal, one end of support column set circular arc chamfering, can be quick in order to one end of support column
Insert in mounting hole.
Preferably, the support column is provided with pad, and pad is fixed in mounting hole.
Pass through above-mentioned technical proposal, pad is set on support column, when support column is fixed in mounting hole, pad can subtract
Gap between small mounting hole and support column, so as to improve the support effect of support column.
Preferably, the pad is U-shaped.
Pass through above-mentioned technical proposal, pad are U-shaped, and when support column is fixed in mounting hole, pad can be inserted in branch
On dagger, the installation of mat piece.
Preferably, it is described support column bottom be provided with support base (.
Pass through above-mentioned technical proposal, support base can increase the contact area with ground, and the support that can improve support column is steady
It is qualitative.
The beneficial effects of the utility model are：The utility model only needs to open up first through hole, on the wallboard of both sides
Two through holes, afterwards again by crossbeam from first through hole through in the second through hole, it is easy to operate, it is not necessary to hang crossbeam
Dress is fixed, easy to operate.

Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
The prefabricated cantilever stair of a kind of two-part as shown in Figure 1, including two blocks of wallboards 1, two fixed on the ground vertically
Bar intersects the prefabricated cantilever stair plate 2 of setting.Offer first through hole 3, the second through hole 4 on two blocks of wallboards 1 respectively, two
The place of intersecting of precast stair plate 2 has the first notch 5, the second notch 6.Worn between the through hole 4 of first through hole 3 and second
There is a crossbeam 7, crossbeam 7 is by the first notch 5, the second notch 6 and supports two blocks of cross one another precast stair plates 2.
As shown in Figures 2 and 3, being stood between crossbeam 7 and ground has one piece of support column 8, and the lower surface of crossbeam 7 is provided with mounting hole 9,
