[0002] During the masonry construction of the secondary structure wall of the concrete frame, the construction workers generally set up a full-length steel pipe scaffolding along the secondary structure wall to facilitate the construction workers to stand in position for masonry construction. The disadvantages of this scaffolding are: first, a large number of steel pipes need to be rented for the construction, and the rental fee is high; second, the installation and disassembly of the scaffolding is large in construction volume, time-consuming and labor-intensive, and the construction cost is high. Utility Model Content

[0003] The utility model aims to provide a secondary structure masonry rolling scaffold on a frame beam, which solves the problem of high construction cost.

[0004] The utility model places two sets of rolling scaffolds on the concrete frame beam, so that the upper sliding roller is against the top surface of the frame beam, and the side sliding roller is in contact with the side of the frame beam. The distance between the two sets of rolling scaffolds is 2000-3000mm; then the wooden springboard is placed on the two supporting rods and tied and fixed. At this time, the construction workers can stand on the wooden springboard between the supporting rods to carry out secondary structure masonry work. When the working height needs to be increased, it only needs to operate the handle to twist the bolt rod to lift it. When it needs to move left and right, it only needs to push the upper sliding roller, and the side sliding roller plays a role of stability and side rolling.

[0005] The utility model rolling scaffold comprises a supporting rod 1, an oblique rod 2, a bolt rod 3, a side roller shaft 4, a side sliding roller 5, a nut 6, a handle 7, an upper sliding roller 8, a cross brace 9, an upper roller shaft 10, and a connecting rod 11. The parts are used in combination. One end of the four oblique rods 2 is welded to the two ends of the two supporting rods 1 in pairs, and the other end is welded to the two sides of the lower end of the bolt rod 3; a nut 6 is screwed into the upper end of each bolt rod 3; a handle 7 is welded to the top of the bolt rod 3; the inner sides of the two nuts 6 are welded at the two ends of the cross brace 9; the middle of the cross brace 9 is horizontally welded Vertically welded above the middle of the connecting rod 11; two upper rollers 10 and four upper sliding rollers 8 form two rolling systems, the two upper sliding rollers 8 on each upper roller 10 are 200mm apart, and the upper sliding roller 8 rotates around the upper roller 10; four side sliding rollers 5 and four side rolling shafts 4 form four rolling systems, and the side sliding rollers 5 rotate around the side rolling shafts 4; the top ends of the four side rolling shafts 4 are respectively vertically welded to the two ends of the two upper rollers 10; the two ends of the connecting rod 11 are vertically welded to the middle of the two upper rollers 10 (see Figure 1 , Figure 2 ).

[0006] Among them, the support rod 1 is made of square steel with a cross-sectional size (length * width) of 40*40, and is 400mm long; the diagonal rod 2 is made of square steel with a cross-sectional size (length * width) of 40*40, and is 300mm long; the bolt rod 3 has a diameter of 40mm and a length of 3000mm; the side roller 4 has a diameter of 40mm and a length of 400mm; the side sliding roller 5 has an outer diameter of 100mm and an inner diameter of 40mm; the nut 6 has a diameter of 40mm; the handle 7 is made of a round tube with a diameter of 30mm and is 300mm long; the upper sliding roller 8 has an outer diameter of 100mm and an inner diameter of 40mm; the cross brace 9 is made of a square tube with a cross-sectional size (length * width) of 100*100, and is 1200mm long; the upper roller 10 has a diameter of 40mm and a length of 300mm-600mm; the connecting rod 11 is made of a square tube with a cross-sectional size (length * width) of 100*100, and is 600mm long.

[0007] When in use, place two sets of rolling scaffolds on the concrete frame beam 12, so that the upper sliding roller 8 is against the top surface of the frame beam 12, and the side sliding roller 4 is in contact with the side of the frame beam 12. The distance between the two sets of rolling scaffolds is 2000-3000mm; then place the wooden springboard 13 on the two support rods 1 and tie them up to fix them. At this time, the construction workers can stand on the wooden springboard 13 between the support rods 1 to carry out secondary structure masonry operations. When it is necessary to increase the working height, just operate the handle 7 to twist the bolt rod 3 to lift it. When it is necessary to move left or right, just push the upper sliding roller 8, and the side sliding roller 5 plays a role of stability and side rolling. When the rolling scaffold is dismantled after use, it can be reused (see Figure 3 , Figure 4 ).

[0008] The utility model has the advantages of simple assembly and convenient operation, which not only avoids the rental of a large number of steel pipes and reduces the rental costs, but also avoids the disassembly and assembly of a large number of scaffolding pipes, saves labor and reduces construction costs.

When it is necessary to move left and right, it is only necessary to push the upper sliding roller 8, and the side sliding roller 5 plays a role in stabilization and side rolling. When the rolling scaffold is dismantled after use, it can be reused.

[0017] When laying the secondary structure wall of the concrete frame of the office building, a secondary structure masonry rolling scaffold on the frame beam was adopted for the construction workers' standing operation, which not only avoided the rental of a large number of steel pipes, reduced the rental cost, but also avoided the disassembly and assembly of a large number of scaffolding pipes, saved labor, was convenient and fast, and had a good effect. The rolling scaffold is used in combination, and the four diagonal rods are welded to the two ends of the two support rods at one end, and the other end is welded to the two sides of the lower end of the bolt rod; a nut is screwed into the upper end of each bolt rod; a handle is welded at the top of the bolt rod; the inner sides of the two nuts are welded at both ends of the cross brace; the middle of the cross brace is welded vertically above the middle of the connecting rod in the horizontal direction; two upper rollers and four upper sliding rollers form two rolling systems, the spacing between the two upper sliding rollers on each upper roller is 200mm, and the upper sliding roller rotates with the upper roller as the center; four side sliding rollers and four side rollers form four rolling systems, and the side sliding rollers rotate with the side roller as the center; the tops of the four side rollers are vertically welded to the two ends of the two upper rollers respectively; the two ends of the connecting rod are vertically welded to the middle of the two upper rollers. When in use, place two sets of rolling scaffolds on the concrete frame beam, so that the upper sliding roller rests on the top surface of the frame beam, and the side sliding roller contacts the side of the frame beam. The distance between the two sets of rolling scaffolds is 2000-3000mm; then place the wooden springboard on the two support rods and tie them to fix. At this time, the construction workers can stand on the wooden springboard between the support rods to carry out secondary structure masonry operations. When the working height needs to be increased, just operate the handle to twist the bolt rod to lift it. When it is necessary to move left and right, just push the upper sliding roller. The side sliding roller also plays a role in stabilization and side rolling. When the rolling scaffold is used, it can be dismantled and reused. The rolling scaffold is simple to assemble and easy to operate. It not only avoids the rental of a large number of steel pipes and reduces the rental costs, but also avoids the disassembly and assembly of a large number of scaffolding pipes, saving labor and reducing construction costs.
