Problems solved by technology

[0004] 1. Safety is not guaranteed: Before the steel bars of the stairs are installed, anti-skid strips are usually nailed at intervals on the stairs as the upper and lower support points. , people fall from time to time;
[0005] 2. The quality of the forming steel bars of the stair slab is affected: After the stair stair slab is installed, the operator uses the formed stair slab steel mesh as an anti-skid facility, tramples up and down, and the binding points, protective layer thickness, spacing, etc. of the steel bars are severely damaged ;
[0006] 3. The finished product of the riser formwork installation is damaged: after the riser formwork is installed, the workers step on the riser formwork up and down, which may easily cause displacement and fall off. During the process of concrete pouring and plastering of the stairs, workers step on the riser formwork to complete Pouring, vibrating, plastering and other processes lead to the displacement of the formwork, which is also one of the reasons for the deviation of the cross-sectional size of the stair steps after the formwork is removed, and the poor appearance of the surface of the stairway components

Embodiment Construction

[0051] Such as Figure 1 to Figure 25 As shown, the reversible stair construction plank road (referred to as "plank road") of the present invention includes a rotatable main beam, a fixed main beam, an upper column I, an upper column II, a lower column I, a lower column II, a step bearing frame, Stair treads, anti-overturn bracing device.

[0052] Such as figure 1 As shown, the upper end of the rotatable main beam is connected to the upper column I, the lower end of the rotatable main beam is connected to the lower column I, and the inner sides of the upper column I and the lower column I are respectively fixedly connected to the bearing I connected to the upper and lower ends of the rotatable main beam. In this embodiment, the rotatable main beam includes an upper rotatable main beam and a lower rotatable main beam, and a rotatable connector is connected between the upper rotatable main beam and the lower rotatable main beam. The lower outer wall of the rotatable connector ...

Abstract

The invention discloses a turnover stair construction plank road, and relates to a building construction technology. The turnover stair construction plank road comprises a rotatable main beam, a fixedmain beam, a first upper vertical column, a second upper vertical column, a first lower vertical column, a second lower vertical column, stepping force-bearing frames, stair pedals, and overturn-preventing support devices. The upper end and the lower end of the rotatable main beam are connected with the first upper vertical column and the first lower vertical column correspondingly; the inner sides of the first upper vertical column and the first lower vertical column are fixedly connected with first bearings which are connected with the upper end and the lower end of the rotatable main beamcorrespondingly; the upper end and the lower end of the fixed main beam are fixedly connected with the second upper vertical column and the second lower vertical column correspondingly; the stepping force-bearing frames are fixedly connected between the rotatable main beam and the fixed main beam; the stair pedals are positioned on the stepping force-bearing frames; the overturn-preventing supportdevices comprise main connecting shafts connected with the middle of the fixed main beam and supporting devices which are connected to the outer ends of the main connecting shafts and can rotate andswing relative to the main connecting shafts; and the rotatable main beam can drive the fixed main beam, the stepping force-bearing frames, the stair pedals and the overturn-preventing support devicesto rotate between the first upper vertical column and the first lower vertical column with the rotatable main beam.

Description

technical field [0001] The invention relates to building construction technology, in particular to a stair construction plank road used in construction. Background technique [0002] After completing the concrete construction of the nth floor of the project under construction, when entering the construction of the n+1th floor, the methods for the construction personnel to go up and down the floors include: using simple wooden ladders, or climbing formwork steel pipe support frames, but the more common The method is: use the building design stair formwork as the main channel for people to go up and down, portable materials and tools. [0003] There are following deficiencies in existing practice: [0004] 1. Safety is not guaranteed: Before the steel bars of the stairs are installed, anti-skid strips are usually nailed at intervals on the stairs as the upper and lower support points. , people fall from time to time; [0005] 2. The quality of the forming steel bars of the ...
