Description

Technical Field

[0001] The invention relates to the technical field of special decoration equipment in building interior decoration, in particular to an outward-exploring cantilevered aerial platform used for side wall construction and applied to building floors. Background Art

[0002] In commercial projects, after the decoration construction is completed, the full-height scaffolding in the atrium will be removed, but the decorative surface of the side wall area of ​​the corridor needs to be repaired, rectified and cleaned. If the traditional full-height scaffolding or double-row scaffolding is installed in this area, there will be some problems. First, the load-bearing capacity of the stone on the ground cannot meet the requirements, which means that the stability of the traditional scaffolding cannot be guaranteed; secondly, the cost of traditional scaffolding is high, which will bring unnecessary economic burden to the project. On the other hand, although the new aluminum alloy scaffolding on the market has good stability, its cost is also relatively high. In view of this, it has become a problem to be solved to design an external cantilevered aerial platform with simple structure, low cost, convenient construction, and can be used for construction in this area. Summary of the invention

[0003] The purpose of the present invention is to solve the above-mentioned problems and propose an externally-explored cantilevered aerial platform which is simple in structure, low in cost, convenient in construction and applicable to building floors.

[0004] To achieve the above-mentioned purpose, the technical solution of the present invention is: an outward-expanding cantilevered aerial platform used for building floors, comprising: a body steel frame welded from a plurality of square tube keels, a cantilevered steel platform welded horizontally extending outward from the top edge of the body steel frame, an inclined steel ladder welded between the bottom square tube keel of the body steel frame and the square tube keel of the cantilevered steel platform, a lifting steel guardrail is arranged on the cantilevered steel platform, a plurality of scaffolding rollers are installed at the bottom of the body steel frame, and the top height of the body steel frame is lower than the corresponding building floor ceiling height so that the cantilevered steel platform can extend to the outside of the building floor.

[0005] The vehicle body steel frame comprises: four bottom rectangular square keels, four top rectangular square keels, four vertical supporting square keels and three horizontal reinforcing square keels in the middle.

[0006] The cantilever steel platform is a plane frame structure formed by welding a number of square keels, and a movable plate is laid on the cantilever steel platform.

[0007] The inclined steel ladder is welded by a plurality of steel keels, the top end of the inclined steel ladder is welded and fixed to the outermost square keel in the cantilevered steel platform, and the bottom end of the inclined steel ladder is welded and fixed to the transverse fixed square keel welded in the rectangular frame of the four bottom square keels.

[0008] A counterweight block is placed between the transverse fixed square keel and the bottom square keel to prevent overturning during construction.

[0009] The lifting steel guardrail includes a plurality of guardrail steel keels and a plurality of punching pins installed on the edge of the cantilevered steel platform. The guardrail steel keels are inserted into corresponding punching pins and are positioned after being adjusted up and down by the punching pins.

[0010] A safety net is provided in the space area between the four top rectangular square keels, the cantilevered steel platform and the three horizontal reinforced square keels in the middle.

[0011] After adopting the above structure, the new type is welded by several square keels, and the cost will be greatly reduced, thus saving a lot of money for the project; four scaffolding rollers are installed at the bottom of the body steel frame, which can be easily and flexibly moved in the corridor to quickly reach the area where construction is required; the counterweight block and safety settings ensure the construction safety of the new type; and the lifting steel guardrail drops to the bottom of the cantilevered steel platform during the movement, which is convenient for moving in the corridor. During construction, the lifting steel guardrail rises to the top of the cantilevered steel platform to protect the construction workers. It can be seen that the new type has the characteristics of simple structure, saving construction costs, easy movement, and high construction safety. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The following is combined with Figure 1-4 The specific implementation manner of the utility model is further described in detail.

[0017] The technical solution of the present invention is: an outward-expanding cantilevered aerial platform used for building floors, comprising: a body steel frame 10 welded by a plurality of square keels, a cantilevered steel platform 20 welded horizontally extending outward from the top edge of the body steel frame 10, an inclined steel ladder 30 welded between the bottom square keel of the body steel frame 10 and the square keel of the cantilevered steel platform 20, a lifting steel guardrail 40 is provided on the cantilevered steel platform 30, and a plurality of scaffolding rollers 50 are installed at the bottom of the body steel frame 10, and the top height of the body steel frame 10 is lower than the height of the corresponding building floor ceiling 60 so that the cantilevered steel platform 20 can extend to the outside of the building floor.

[0018] The vehicle body steel frame 10 includes: four bottom rectangular square keels 11 , four top rectangular square keels 12 , four vertical supporting square keels 13 , and three horizontal reinforcing square keels 14 in the middle.

[0019] The cantilever steel platform 20 is a planar frame structure formed by welding a number of square keels, and a movable plate 70 is laid on the cantilever steel platform.

[0020] The inclined steel ladder 30 is welded by a plurality of steel keels, the top end of the inclined steel ladder 30 is welded and fixed to the outermost square keel in the cantilevered steel platform 20, and the bottom end of the inclined steel ladder 30 is welded and fixed to the transverse fixed square keel 15 welded in the rectangular frame of the four bottom square keels 11.

[0021] A counterweight block 80 is placed between the transverse fixed square keel 15 and the bottom square keel 11 to prevent overturning during construction.

[0022] The lifting steel guardrail 40 includes a plurality of guardrail steel keels 41 and a plurality of punching pins 42 installed on the edge of the cantilevered steel platform 20. The guardrail steel keels 41 are inserted into corresponding punching pins 42 and are positioned after being adjusted up and down by the punching pins 42.

[0025] During use, the cantilever steel platform 20 extends to the outside of the building floor. After the workers reach the top via the inclined steel ladder 30, they raise the liftable steel guardrail 41, lay movable boards 70 on the cantilever steel platform 20, and set a safety net 90 under the liftable steel guardrail 40.
