People who have cottages or country houses, very often do a lot of things themselves. And there comes a time when there is a need to do something worthwhile and necessary.
For example, it occurred to you to make an attic from an attic to an attic.
Then you have to build a ladder yourself.
This is not an easy task, which requires careful preparation.
Develop a scheme of the ladder, execute its workdrawing. All this can be done both with traditional drawing tools, and with the help of computer programs. Calculate the characteristics, the optimal number of steps and the distance between them.
Cut out of the boards steps, the number of whichPre-select, and two strings, to which the boards will be attached. Do not forget to leave an oblique cut on top of the bowstring, for a tight connection of the ladder with the highest surface. The second bowstring you do not need if there are no gaps on the stairs.
Cut out the supporting bars. Their number should be exactly twice as many steps. Please note that their length should be slightly smaller than the length of the string. When connecting the beams with the string, see that they pass through the same intervals, take into account the height of the steps.
Try on the strings where you will find yourselfConstruction of stairs. Dig two holes with a depth of about 20 cm. Screw the strings to the highest horizontal platform, making sure that the distance between them is equal to the width of the ladder.
Prepare the concrete mortar, and pour the bottomEnd of the string, which in advance set in the pit. Now wait about 12 hours until the concrete hardens. Secure the steps with the screws that are on the uneven bars, and the ladder is ready.
