The utility model relates to a device for elevator attaches wall, include: be fixed in a pair of extension frame that just extends towards the elevator standard festival on the girder steel of building, said extension frame includes: the roof, the top surface of roof is formed with the attachment point, a plurality of vertical supporting rod, support connect in said roof with between the said girder steel, locate to extend and attach the wall frame between frame and elevator standard festival, be connected with standard the saving of attachment point and elevator of extending the frame. The extension frame is adhered to in the installation on the building girder steel to adhere to extending the shelf location standard, thereby will be under construction the standard festival of elevator connecting on the building, effectively having solved because the indentation of building part floor, this part floor of building and distance between the guide rail of the elevator of being under construction are greater than the distance of other part floors, can not equally use the current wall frame that attaches to carry out adnexed problem with other part floors.
