The stair can be divided into single-run stair, double-run stair and multi-run stair according to the bench, and the plane shape of bench has sharp, broken line and curved, has that what a lot of prefabricated stairs adopted is wooden, and present prefabricated stair most all do not possess the function of adjusting the size, reducing the volume to inconvenient concatenation and dismantlement.
SUMMERY OF THE UTILITY MODEL
To solve the problems set forth in the background art described above. The utility model provides a prefabricated staircase of convenient concatenation has solved present prefabricated staircase most and has not possessed the regulation size, reduces the function of volume to the problem of inconvenient concatenation and dismantlement.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a prefabricated staircase of convenient concatenation, includes first stair tread, the equal sliding connection in both sides of first stair tread has second stair tread, the top fixed mounting of second stair tread has the spliced pole, the bottom fixed mounting of second stair tread has the connecting sleeve, one side fixed mounting of second stair tread has the mounting panel, the surface of mounting panel evenly is provided with fixing bolt.
Preferably, the first stair plates are connected with the second stair plates through fixing bolts, and the number of the second stair plates is two.
Preferably, the connecting column and the connecting sleeve are connected through a fixing bolt.
Preferably, a fixed disc is fixedly mounted at one end of the connecting sleeve.
Preferably, the surfaces of the first stair plate and the second stair plate are provided with anti-skid grains.
Preferably, the diameter size of connecting sleeve is greater than the diameter size of spliced pole.
Compared with the prior art, the beneficial effects of the utility model are that:
this prefabricated stair of convenient concatenation, the mode that utilizes first stair board and second stair board sliding connection has played the effect of adjusting stair board length on the one hand, on the other hand can reduce the volume of device, it is connected with the spliced pole on another stair board to utilize the connecting sleeve on one of them stair board, the effect of making things convenient for the concatenation of prefabricated stair has been played on the one hand, thereby can adjust the overall height of prefabricated stair according to the quantity of concatenation, thereby on the other hand control the length of being connected between spliced pole and the connecting sleeve plays the effect of adjusting interval between two stair boards, the suitability of improving the device, the effectual inconvenient regulation size of prefabricated stair in the past of having solved, be difficult to reduce the volume, the problem of inconvenient concatenation.
