Attached scaffold capable of dispersing stress

Abstract

The utility model discloses an attached scaffold capable of dispersing stress, and belongs to the technical field of attached scaffolds. According to the utility model, the climbing frame is fixed on the floor through the plurality of connecting assemblies, so that constructors can conveniently construct the exterior of a stair; specifically, a cantilever beam is fixed to a floor slab through fixing bolts, and secondary fixing is conducted through preset floor slab bolts; secondly, the floor bolts are connected with the telescopic pull rods through the connecting plates. When a load is applied to the scaffold, one end of the cantilever beam bears downward pressure, the other end of the cantilever beam bears upward force, and therefore the floor bolt bears upward force; and meanwhile, the telescopic pull rod is subjected to downward pulling force, so that the floor bolts are subjected to downward pulling force. Due to the balance of the upward force and the downward force, the force of the connecting assembly and the telescopic pull rod in the vertical direction is uniformly dispersed, so that the problem that the stress distribution of a traditional attached scaffold is not uniform is solved, and the safety and the stability of the scaffold are improved.

[0030] Stress dispersion attached scaffold embodiment:

[0031] As Figures 1-3 shown, the stress dispersion attached scaffold comprises a climbing frame 7 and a scaffold 8 vertically and slidingly connected with one side of the climbing frame 7. Here, the sliding connection between the scaffold 8 and the climbing frame 7 is realized by existing lifting devices or sliding devices. That is, the scaffold 8 can move upwards within a certain range relative to the climbing frame 7. The scaffold 8 is provided with scaffold boards 9 at intervals, which provide a platform for the construction personnel to walk and work.

[0032] The other side of the climbing frame 7 is fixedly connected with the floor slab 1 through a plurality of connecting assemblies 2. That is, the scaffold 8 is indirectly fixed relative to the floor slab 1. The connecting assemblies 2 are provided with two in the horizontal direction and three in the vertical direction. By fixing the connecting assemblies 2 with the floor slab 1 in the horizontal and vertical directions, the overall stability of the scaffold 8 can be effectively enhanced.

[0033] In order to realize uniform dispersion of stress, the connecting assemblies 2 in the vertical direction are connected through telescopic pull rods 3.

[0034] Specifically, the floor slab 1 is provided with a floor bolt 6 penetrating the floor slab 1. The floor bolt 6 is fixed in advance, and has better stability than that of a hole drilled later. The floor bolt 6 can tightly connect the scaffold 8 with the building structure, form a stable and reliable support system, effectively improve the stability and load-bearing capacity of the scaffold 8, and thus ensure the safety of the construction personnel. In addition, the scaffold 8 does not need to be drilled later, and the fixing efficiency of the scaffold 8 is improved.

[0035] The connecting assembly 2 includes a horizontal cantilever beam 21, a connecting plate 22, a connecting bolt 23 and a fixing bolt 24. The connecting bolt 23 and the connecting plate 22 are matched to fix the telescopic pull rod 3 and the floor bolt 6. The fixing bolt 24 is used to fix the cantilever beam 21 and the floor slab 1. Specifically, the connecting plate 22 includes a horizontal plate 221 and an inclined plate 223 connected with the horizontal plate 221. The horizontal plate 221 is provided with a first connecting hole 222, and the inclined plate 223 is provided with a second connecting hole 224. One end of the cantilever beam 21 is fixedly connected with the climbing frame 7, and the other end is fixedly connected with the floor slab 1 below through a plurality of fixing bolts 24. The floor bolt 6 above the floor slab 1 penetrates the connecting hole of the cantilever beam 21 and is screwed with a nut to fix the cantilever beam 21 on the floor slab 1. The floor bolt 6 below the floor slab 1 penetrates the first connecting hole 222 and is screwed with a nut to fix the connecting plate 22. One end of the telescopic pull rod 3 is vertically rotatably connected with one end of the cantilever beam 21. The other end is fixedly connected with an extension plate 4 parallel to the inclined plate 223. The extension plate 4 is provided with a third connecting hole 5. The connecting bolt 23 penetrates the second connecting hole 224 and the third connecting hole 5 and is screwed with a nut to fix the other end of the telescopic pull rod 3 with the floor bolt 6.

[0036] When the scaffold 8 has a load, the end of the cantilever beam 21 close to the scaffold 8 is subjected to a downward pressure, and the end away from the scaffold 8 is subjected to an upward force, so that the floor bolt 6 is also subjected to an upward force. When the scaffold 8 has a load, the telescopic pull rod 3 is subjected to a downward tension, so that the floor bolt 6 is subjected to a downward tension. At this time, the upward and downward forces of the floor bolt 6 are balanced, that is, the forces of the connecting assembly 2 and the telescopic pull rod 3 in the vertical direction are balanced, and the stress is uniformly dispersed.

[0037] In order to improve the adaptability of the attached scaffold 8, the cantilever beam 21 includes a cross beam 211 and a rectangular high-rise member 212. A plurality of fixing bolts 24 penetrate the cross beam 211 and the high-rise member 212 to be fixedly connected with the floor slab 1. The connecting hole is formed in the bottom plate of the high-rise member 212. That is, as shown in FIG. 4, the cross beam 211 is fixedly connected with the high-rise member 212 through the fixing bolts 24, and the telescopic pull rod 3 is fixedly connected with the high-rise member 212 through the connecting bolt 23 and the fixing bolt 24. Figure 1As shown, the existing building is provided with a cantilever balcony; because the bearing of the cantilever balcony is generally, when the cantilever beam 21 is fixed, the stress point is arranged on the deeper floor 1; because the balcony is higher than the internal floor 1, in order to ensure that the cantilever beam 21 can be horizontally arranged, the cantilever beam 21 with the heightening piece 212 is designed to avoid the damage of the existing building by the scaffold 8.

[0038] In order to enhance the connection stability, the square steel gasket is arranged between the fixing bolt 24 and the cantilever beam 21. The square steel gasket can uniformly disperse the stress of the bolt, avoid local stress concentration, thereby enhancing the connection stability between the cantilever beam 21 and the fixing bolt 24.

[0039] In order to ensure the structural strength, the horizontal plate 221 and the inclined plate 223 are integrally connected.

[0040] The extension plate 4 comprises clamping pieces and connecting pieces, the clamping pieces and the connecting pieces are integrally formed, the clamping pieces are used for fixing the end of the telescopic pull rod 3, and the connecting pieces are used for connecting with the inclined plate 223. The telescopic pull rod 3 and the floor bolt 6 are fixed conveniently. The design of the integrally formed clamping pieces and connecting pieces can effectively improve the structural strength, connection reliability and construction efficiency of the extension plate 4, and reduce the deformation risk and maintenance cost.

[0041] In actual use, the connection assembly 2 is assembled and installed on the floor 1 of the building according to the above content; when the height of the climbing frame 7 and the scaffold 8 needs to be increased, the telescopic pull rod 3 is installed on the basis of the installed connection assembly 2, the other end of the telescopic pull rod 3 is fixed on the corresponding floor bolt, the connection assembly 2 is installed on the upper floor 1, and finally the new climbing frame 7 and the scaffold 8 are connected through the connection assembly 2.

[0042] The above is only a preferred embodiment of the present application, and does not limit the present application, any simple modification, change and equivalent structure change according to the technical essence of the present application are still within the protection scope of the technical scheme of the present application.
