Problems solved by technology

[0002] The construction of stairs is essential in the construction of modern floor buildings. Although there are elevators installed in the floors, it is more convenient to go up and down the stairs, but if a fire occurs, the elevator cannot be used. At this time, the stairs become emergency passages. Therefore, the construction of stairs is very important, and when building stairs, it is necessary to paint the steps of the stairs, and put a cement mortar surface on the steps of the stairs. However, when the elastic or pull wire is used, the height of the stair steps will be inconsistent after the painting is completed, and the width of the stair steps will also be inconsistent after the painting is completed, the flatness is poor, and the construction efficiency is low, which increases the construction cost , the quality of painting and the appearance of painting are not easy to guarantee

Embodiment 1

[0028] Embodiment 1, the painting of the stair steps is an indispensable item in the construction process of modern buildings. When the steps of the stairs are painted, methods such as snapping wires and pulling wires are often used to determine the reference line. It may lead to inconsistent step heights of the stairs, and may also lead to inconsistent step widths of the stairs after painting, poor flatness, low construction efficiency, and difficulty in guaranteeing the quality of painting and the appearance of painting.

[0029] For the problems referred to above, the present invention proposes a kind of stair step painting tool, such as figure 1 , figure 2 As shown, the present embodiment device comprises two ladder-shaped supports 5, and the number of steps of the ladder-shaped supports is three layers, and the center of the ladder-shaped supports 5 is provided with a ladder-shaped guide rail 18, and the head end and the end of the ladder-shaped guide rail 18 There is a...

Embodiment 2

[0035] Embodiment 2, a stair step painting tool in this embodiment will be described centering on the differences from Embodiment 1.

[0036] In this example, if Figure 5 As shown, a pressing plate 14 is installed on the top of the lifting rod, and handles 13 are installed on both sides of the limit nut 7. When the limit nut 7 needs to be adjusted, there is no need to use tools such as wrenches, and the handle 13 can directly The stop nut can be adjusted, and a through hole is arranged in the middle part of the I-shaped pulley, and the anti-rotation limit pin 12 is matched and embedded in the through hole, and an anti-rotation card slot 11 is vertically provided on the side of the lifting rod, and the anti-rotation card The top of the groove 11 has a certain distance from the top of the elevating rod 3, and the anti-rotation stopper pin 12 is stuck in the anti-rotation draw-in groove 11 by the through hole in the middle part of the I-shaped pulley.

Abstract

The invention belongs to the field of building construction painting, and in particular relates to a stair step painting tool, which includes a ladder-shaped support, a support mechanism is arranged at the head end and the end of the ladder-shaped support, and a limit mechanism and a dust-scraping mechanism are arranged on the ladder-shaped support. In addition, pulleys are also set in the guide rails in the ladder-shaped bracket, and the ladder-shaped bracket is designed. It is not necessary to remove the spring wire and the pull wire on the wall to determine the reference line, and directly adjust the height of the support mechanism to carry out the fixed painting of the stair steps, and The support seat of the supporting mechanism can make the painting tool more stable when painting the steps of the stairs, so that it will not slip or move during the painting process. The operation is simple, time-saving and labor-saving, and it can be recycled to save resources. , has a good application prospect.
