Description

Technical Field

[0001] The utility model relates to the field of building construction devices, and more specifically, to a high-altitude construction platform. Background Art

[0002] Eaves are often used in modern buildings. Eaves are the part of the roof that extends out of the building facade. Its main function is to facilitate the drainage of the building roof and prevent water from dripping on the facade. In addition to the anti-leakage function, it is often used in the aesthetic design of the building to ensure the overall beauty of the building.

[0003] As a cantilever structure, the eaves cannot be used as the main load-bearing structure to arrange the load. In addition, due to its structural design that extends out of the roof, the insulation and coating construction on the lower surface of the eaves and the building facade immediately below the eaves is relatively complicated, and it is often necessary to set up special scaffolding and other facilities to assist in the construction. Moreover, if construction work such as maintenance is still required after the scaffolding is removed, it is often necessary to rent large equipment such as a truck crane for assistance. It is not suitable for maintenance work with a long construction period and the overall cost is also high.

[0004] Patent publication number CN115370119A discloses a construction platform for a long cantilever concrete cantilever ceiling, which forms a stable construction platform by arranging a hanging basket device on the upper part of the cantilever and assuming fixed facilities on the top floor. However, this solution is suitable for buildings with cantilever having good bearing capacity, and it is necessary to use the top floor of the building to set up the construction platform, which is not convenient for conventional construction such as facade paint construction, plastering at the bottom of the cantilever, and is not suitable for later maintenance of the building facade. Therefore, it is necessary to propose a construction platform that does not need to be directly located on the cantilever and is suitable for most working conditions. Utility Model Content

[0005] One purpose of the utility model is to provide an aerial construction platform, which can avoid applying load to the overhanging eaves structure and can be applied to various building facade construction operations affected by the overhanging eaves.

[0006] In order to achieve these purposes and other advantages according to the utility model, according to one aspect of the utility model, the utility model provides an aerial work construction platform, which is arranged on the roof of a building with an overhanging eaves, including: a platform bracket, which is provided with a walking mechanism and a supporting structure, the walking mechanism drives the supporting structure to travel on the roof of the building, and the upper part of the supporting structure is horizontally connected to multiple lifting beams, one end of the lifting beam is connected to a counterweight, and the other end of the lifting beam is cantilevered out of the overhanging eaves; a hydraulic lifting mechanism, which includes a fixed arm and a rotating arm, one end of the fixed arm is connected to the end of the lifting beam, and the other end of the fixed arm is fixed with a first hinge block, and a second hinge block is fixed on the fixed arm, the second hinge block is rotatably connected to the end of a first hydraulic rod, the middle part of the rotating arm is rotatably connected to the first hinge block, one end of the rotating arm is rotatably connected to the other end of the first hydraulic rod, and the other end of the rotating arm is fixedly connected to a platform hanging column; a construction platform, which is fixedly connected to several platform hanging columns.

[0007] Preferably, the bottom end of the platform suspension column is rotatably connected to a platform bottom beam, the other end of the platform bottom beam is close to the building, and a second hydraulic rod is rotatably connected between the beam body of the platform bottom beam and the column body of the platform suspension column connected thereto.

[0008] Preferably, the bottom surfaces of two adjacent platform bottom beams are commonly connected to a plurality of bottom plate beams, and the upper surfaces of all the bottom plate beams are commonly fixed with grid plates.

[0009] Preferably, a plurality of connecting beams are connected between adjacent platform suspension columns, and steel meshes are fixed between the connecting beams.

[0010] Preferably, the bottom plate beam is perpendicular to the platform bottom beam, both ends of the bottom plate beam extend outwardly from the platform bottom beam, and the end of the bottom plate beam is fixedly connected upward with a guardrail.

[0011] Preferably, the column body of the platform suspension column and the beam body of the corresponding platform bottom beam are detachably connected to a suspension inclined beam.

[0012] Preferably, a ladder is fixed to a side of the connecting beam close to the building.

[0013] The utility model at least has the following beneficial effects:

[0014] First, the structure of the utility model occupies less space and requires less labor for support. The platform bracket is movable and can be moved along the edge of the roof as the construction progresses. The construction platform can cover a larger construction range.

[0015] Second, the hydraulic lifting mechanism adopted in the utility model can lift the construction platform out of the roof and then fold it down. The construction platform is also designed to be foldable. When the hydraulic lifting mechanism lowers the platform hanging column from a horizontal state to a vertical state, the second hydraulic rod can be used to unfold the construction platform, making it convenient for construction workers to stand on the construction platform to carry out construction on the bottom of the eaves and the part of the facade immediately adjacent to the eaves.

[0025] like Figures 1 to 4 As shown, the utility model provides an aerial work construction platform, which is arranged on the roof of a building 1 with an overhanging eaves 10, comprising: a platform bracket 2, which is provided with a walking mechanism 21 and a supporting structure 210, wherein the walking mechanism 21 drives the supporting structure 210 to travel on the roof of the building 1, wherein the upper part of the supporting structure 210 is horizontally connected to a plurality of hoisting beams 22, wherein one end of the hoisting beam 22 is connected to a counterweight 20, and the other end of the hoisting beam 22 is cantilevered out of the overhanging eaves 10; a hydraulic lifting mechanism 4, which comprises a fixed arm 40 and a rotating arm 44, wherein the One end of the fixed arm 40 is connected to the end of the lifting beam 22, and the other end of the fixed arm 40 is fixed with a first hinge block 41, and a second hinge block 42 is fixed on the fixed arm 40, and the second hinge block 42 is rotatably connected to the end of a first hydraulic rod 43, and the middle part of the rotating arm 44 is rotatably connected to the first hinge block 41, and one end of the rotating arm 44 is rotatably connected to the other end of the first hydraulic rod 43, and the other end of the rotating arm 44 is fixedly connected to a platform suspension column 31; a construction platform 3 is fixedly connected to several platform suspension columns 31.

[0026] In the present technical solution, the building 1 has conventional roofing structures such as an overhanging eave 10 and a parapet 11. The overhanging eave 10 extends out of the outer wall 12. The walking mechanism 21 is a trolley with multiple walking wheels with a certain steering function. The supporting structure 210 is a steel column or a steel frame. The hoisting beam 22 is connected to the supporting structure 210 by welding or high-strength bolts. Each platform bracket 2 includes two hoisting beams 22 of the same size. The hoisting beams 22 are parallel and aligned with each other. The hoisting beam 22 is located at one end of the roof of the building 1 and a counterweight 20 is hung by a steel cable or a frame. During the movement, the counterweight 20 does not contact the roof of the building 1, the hoisting beam 22 is higher than the parapet 11, and the other end extends out of the roof of the building 1, one end of the fixed arm 40 is fixedly connected to the end of the hoisting beam 22 extending out of the building 1 by bolts or welding, the other end of the fixed arm 40 is welded with a first hinge block 41, and the upper surface of the fixed arm 40 is welded with a second hinge block 42, the first hinge block 41 and the second hinge block 42 are both steel box structures, both of which are provided with through holes for pins to be passed through, and the integrity of the two fixed arms 40 can be improved by adding a cross beam.

[0027] In the present technical solution, the rotating arm 44 is a steel box structure, a through hole matching the first hinge block 41 is opened in the middle thereof, the middle part of the rotating arm 44 is rotatably connected to the first hinge block 41 through a pin shaft, a through hole is opened at one end of the rotating arm 44 and is parallel to the axis of the through hole on the second hinge block 42, the two ends of the first hydraulic rod 43 are rotatably connected to the through hole of the second hinge block 41 and the through hole of the rotating arm 44 through a pin shaft, the other end of the rotating arm 44 is connected to the platform hanging column 31, and the other end of the platform hanging column 31 is fixed with the construction platform 3, such as Figure 2 As shown, the construction platform 3 is a foldable platform so as to extend outward from the overhanging eaves 10 along with the platform hanging column 31 .

[0028] Before use, the first hydraulic rod 43 is retracted, so that the rotating arm 44 drives the platform hanging column 31 and the construction platform 3 to be lifted and fixed. At this time, the rotating arm 44 is in a state approximately horizontal, and the rotating arm 44 is extended out of the eaves 10 by the walking mechanism 21. The first hydraulic rod 43 is extended and pushed to rotate the rotating arm 44 around the hinge point between it and the first hinge block 41, driving the platform hanging column 31 and the construction platform 3 from the nearly horizontal state to a vertical state. At this time, the construction platform 3 is suspended by the platform hanging column 31 and close to the outer wall 12. Construction personnel can enter the construction platform 3 to construct the lower surface of the eaves 10 and the outer wall 12 at the junction with the eaves 10. After each construction is completed, the walking mechanism 21 is moved to the next construction position. The technical solution can be applied to the construction and maintenance of building facades, and there is no need to occupy the top floor space of the building. The construction is easier to operate than the conventional hanging basket device.

[0029] In another technical solution, the bottom end of the platform sling 31 is rotatably connected to the platform bottom beam 32, and the other end of the platform bottom beam 32 is close to the building 1. A second hydraulic rod 33 is rotatably provided between the beam body of the platform bottom beam 32 and the column body of the platform sling 31 connected thereto. In this technical solution, a sling pin block 311 is welded to the platform sling 31, and a bottom beam pin 321 is fixed to the platform bottom beam 32. The two ends of the second hydraulic rod 33 are rotatably connected to the sling pin block 311 and the bottom beam pin 321 respectively. The second hydraulic rod 33 can be extended to make the platform sling 31 and the platform bottom beam 32 in a vertical state. The platform bottom beam 32 is connected to The platform plate or frame can be used for construction workers to stand. Since the construction platform 3 must first extend outward from the roof of the building 1 and then be lowered by rotation, the size of the construction platform 3 also needs to meet the construction requirements of normal eaves 10 and exterior walls 12. In order for the construction platform 3 to not conflict with roof structures such as the parapet 11, the construction platform 3 needs to be folded to a certain extent. Each platform bottom beam 32 is rotatably connected to the corresponding platform suspension column 31 through a pin shaft. When the construction platform 3 is folded, the second hydraulic rod 33 is retracted to the shortest. At this time, the platform bottom beam 32 and the platform suspension column 31 form an angle, which facilitates the extension of the platform suspension column 31 and the construction platform 3 from the roof of the building 1 in this technical solution 1.

[0030] In another technical solution, the platform bottom beam 32 is horizontal, and the bottom surfaces of two adjacent platform bottom beams 32 are commonly connected to multiple bottom plate beams 35. The upper surfaces of all bottom plate beams 35 are commonly fixed with a grating plate 350. The bottom plate beams 35 can be connected to the platform bottom beam 32 by welding or bolts. The grating plate 350 can be in the form of a metal frame with a steel wire mesh to reduce the weight, and construction workers can stand on the grating plate 350.

[0031] In another technical solution, a plurality of connecting beams 36 are connected between adjacent platform columns 31, and steel meshes 360 are fixed between the connecting beams 36. The connecting beams 36 are steel sections to improve the stability between the platform columns 31. The steel meshes 360 are connected to the connecting beams 36 or the platform columns 31 by inserts, bolts or welding, and the steel meshes 360 serve as the enclosing structure of the construction platform 3.

[0032] In another technical solution, the bottom plate beam 35 is perpendicular to the platform bottom beam 32 , and both ends of the bottom plate beam 35 extend outward from the platform bottom beam 32 . The end of the platform bottom beam 32 is fixedly connected upward with a guardrail 38 , which is an enclosed structure of the construction platform 3 .

[0033] In another technical solution, the column body of the platform suspension column 31 and the beam body of the corresponding platform bottom beam 32 are detachably connected with a suspension inclined beam 34. In this technical solution, a suspension column fixing plate 312 is fixed on the column body of the platform suspension column 31, and a bottom beam fixing plate 322 is fixed on the beam body of the platform bottom beam 32. Bolt holes are provided on the suspension column fixing plate 312 and the bottom beam fixing plate 322. The suspension inclined beam 34 is a steel structure, and bolt holes matching the suspension column fixing plate 312 and the bottom beam fixing plate 322 are provided at both ends. When the second hydraulic rod 33 is propped up to make the platform bottom beam 32 and the platform suspension column 31 vertical, the suspension inclined beam 34 is manually bolted to improve the stability of the construction platform 3 and avoid failure of the second hydraulic rod 33 during use, thereby causing safety accidents.

[0034] In another technical solution, a ladder 37 is fixed to the side of the connecting beam 36 close to the building 1, and construction workers can enter the construction platform 3 from the eaves 10 via the ladder 37.

It can be fully applied to various fields suitable for the utility model. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the utility model is not limited to the specific details and the illustrations shown and described herein.
