Modular stair tread and construction method

Abstract

The present invention relates to a modularized stair tread and its construction method. It is characterized by that the underside of stair-tread is equipped with fixedly-connected solefplate and locking plate, the stair tread is placed on the surface of stairs, and the soleplate is positioned outside of surface of stairs, and the locking plate is placed against the vertical surface of the stairs, and the horizontal block of a connecting plate is fixedly connected with soleplate, and the top block of the level-regulating plate is fixedly connected with vertical block of connecting plate, when the stair tread is fixedly connected on the surface of stairs, and the bottom block of the level-regulating plate is fixedly connected on the vertical surface of stairs, so that the above-mentioned method can be used for making the invented stair tread.

Description

【Technical field】 [0001] The invention relates to a stair tread and a construction method thereof. 【Background technique】 [0002] Because there are many high-rise buildings everywhere, the construction and quality of the stairs are very important. Such as figure 1 , 2 As shown, the general stair tread and its construction steps are as follows: 1. First fill the gasket 20 in the recess 111 of the stair tread 11 of the cement stair 10 formed by grouting to correct the level, and then place a three-ply board 21 on the stair tread 11 Lay the bottom; 2. Drill several through holes 221, 211 with the wooden stair tread 22 together with the plywood 21, and simultaneously drive the corresponding number of geckos 23 into the through holes 221, 211 and the stair tread 11, so that the stair tread 22 is fixed Three, put the timber button 24 corresponding to the through hole 221 size and shape into the through hole 221; four, paint the stair tread 22, and then adopt the same construct...

AI Technical Summary

Problems solved by technology

The gravity exerted virtually on the stair treads 22 every day, in hot and humid climates, coupled with the thermal expansion and contraction characteristics of wood, will cause the stair treads 22 and stair risers 25 to deform, crack, and fall off. In severe cases, it will be like a domino effect. In addition to complete refurbishment, professional construction and renovation are required

[0004] 2. Due to the habit of stepping on stairs, most people habitually step on the outer edge of the stair tread 22 when stepping on the stairs, so the outer edge of the stair tread 22 bears the largest force, that is, the stress on the stair tread 22 is uneven, plus the damp heat as mentioned above Climate and wood have characteristics of thermal expansion and contraction. The stair treads 22 and stair kick boards 25 will be deformed, cracked, and fall off, and they need to be completely refurbished

[0005] 3. Due to the improvement of people's quality of life and the popularity of DIY products nowadays, the general construction structure of stair treads cannot meet the needs of many enthusiasts.
