[0002] To meet the requirements for indoor solar radiation in the building project, a continuous courtyard extending from ground level to the roof is planned. During the construction of the main building structure, the courtyard should be enclosed to ensure the safety of the construction work. The conventional solution is to erect a steel tube scaffold or a cantilevered I-frame scaffold as a working platform in the courtyard.

[0003] However, since the courtyard area is smaller, the height-to-width ratio of the scaffolding exceeds the limit as the scaffolding structure grows taller, leading to a decrease in the scaffolding's stability and an increased potential safety risk. Furthermore, there is a risk of the scaffolding falling and collapsing during subsequent dismantling. The costs for erecting and dismantling the scaffolding are high, the material rental period is long, and the overall economic viability is poor. Summary of the utility model

[0004] The purpose of the present utility model is to provide a protective platform for a courtyard by overcoming the disadvantages of conventional steel tube scaffolding as a working platform for courtyard areas, such as high safety risks and poor economic efficiency.

One end of the chain component 6 is welded to the platform plate body 1, and the other end is connected to the limiting component 5, so that after the limiting component 5 has been pulled out of the platform plate body 1, the limiting component 5 is connected via the chain component 6 to prevent it from falling. The limiting component 5 is a pin; the platform plate body 1 is provided with a limiting hole 7, and the pin is detachably connected to the limiting hole 7.

[0044] In one or more embodiments, the L-shaped components 2 are detachably connected to the platform plate body 1, and different sized support plates 100 are adapted by exchanging differently sized L-shaped components 2.

[0045] In particular, the protective platform is characterized by the fact that one end of the rectangular platform body 1 is provided with round steel lifting lugs as lifting components 4 to facilitate lifting and positioning of the platform body 1. Two L-shaped components 2 are arranged at the other end of the rectangular platform body 1. After being connected to the platform body 1, the L-shaped components 2 form a U-shaped bayonet 3. Two pins are arranged on the platform body 1, which penetrate the platform body 1 so that the ends of the two pins can each be inserted into the two U-shaped bayonets 3.

[0046] Specifically, a 40 mm × 40 mm × 3 mm rectangular tube, sized according to the courtyard dimensions, is used to weld a frame component 11 measuring 3000 mm in length and 1000 mm in width. A 2 mm thick sample steel plate is placed on the upper part of the frame component 11 as a support plate 12. One end of the platform plate body 1 is fitted with a Φ12 round steel lifting ring as a lifting component 4, and the other end is fitted with a rectangular tube at the bottom of the end position to form an L-shaped component 2. A Φ14 round steel pin is attached to the platform plate body 1 as a limiting component 5. After the installation of the protective platform is complete, the L-shaped component 2 can be clamped to the underside of the platform plate body 1 with the support plate 100 of the main structure, and the boundary of the platform plate body 1 is achieved by the bolt fastening to prevent the protective platform from tipping over and shifting during the construction process.

[0047] Specifically, a construction process flow for a protective platform for an inner courtyard is provided as follows. (1) Design

[0048] Depending on the courtyard size, a 40 mm × 40 mm × 3 mm rectangular tube is used to weld a frame component 11 with a length of 3000 mm and a width of 1000 mm. A 2 mm thick steel plate is placed on the upper part of the frame component 11 as a support plate 12, and a Φ12 round steel lifting ring is positioned at one end of the platform. At the other end, an L-shaped support plate 100 with a bayonet fitting is attached to the underside of the end position using a rectangular tube. A Φ14 round steel bolt is used, and the L-shaped bayonet fitting at the lower end of the device can be clamped to the main support plate 100 after completion of the protective installation. (2) Production A. According to the drawing, the courtyard measures 3300 mm × 1200 mm. After subtracting the size of the template for the surrounding components, the clear area of ​​the courtyard is 3200 mm × 1000 mm. Therefore, the manufactured size of platform slab 1 is 3000 mm × 1000 mm, and the 200 mm allowance at the front end of platform slab 1 is convenient for disassembling the platform slab 1 for handling. The platform consists of two rectangular tubes, each 3000 mm long and measuring 40 mm × 40 mm × 3 mm, and six rectangular tubes, each 1000 mm long and measuring 40 mm × 40 mm × 3 mm, welded together to form a frame component 11. B. Two L-shaped components 2 are manufactured by welding from four rectangular tubes with a length of 200 mm and a size of 40 mm × 40 mm × 3 mm. C. A Φ16 circular hole is opened on two corner parts of the frame component 11 with the L-shaped component 2 as a limiting hole 7 to facilitate the installation of a Φ14 round steel bolt.

[0049] The bolt is welded to the end of the platform plate body 1 via an iron chain (chain component 6) to prevent it from falling off during platform dismantling. A Φ12 round steel lifting ring is welded to the other end of the platform plate body 1.

[0050] D. 2 mm thick steel pattern plates are placed completely on the top of the frame element 11, and the steel plate element is welded to the frame element 11.

[0051] Specifically, a procedure for arranging a protective platform for a courtyard on site is provided as follows. A. The protective platform is lifted into place in the courtyard using a tower crane by passing a wire rope through the hoist ring. B. The protective platform is placed in the courtyard, and one end of the L-shaped component 2 is moved so that the underside of the platform plate body 1 is clamped to the support plate 100 of the main body structure. A pin is inserted from the top of the platform plate body 1 into the limiting hole 7, so that the support plate 100 is firmly connected to the platform plate body 1. C. After completion of the construction of the main structure of this layer, the protective platform is transported to the next layer. During the lifting process, the steel cable of the tower crane is guided through the lifting flange and secured, then the pin is pulled out and the protective platform is pushed forward to separate the L-shaped component 2 from the support plate 100 of the main structure, thus completing the lifting and rotation process.

[0052] The cost analysis is presented in detail as follows.

[0053] Four 26-story buildings (78 m high) are planned, each with four courtyards.

[0054] We use the traditional protective platform by constructing a steel tube frame for the ground: 8.8 (planned perimeter length) × 32 (unit price) × 78 (height) = 21964.8 Yuan; and 4 × 4 × 21965.8 = 351436.8 Yuan.

[0055] Use of a novel courtyard security device: The production cost for a single platform is 1400 RMB, the total cost is 4 × 4 × 1400 = 22400 RMB.

[0056] Cost reduction rate: (351436.8-22400) / 351436.8=93.62%.

[0057] In comparison, using the courtyard protective platform saves 329,036.8 yuan compared to a traditional ground scaffold, representing a significant economic advantage. The protective design is simple, easy to construct, extremely practical, easy to manufacture, and easy to assemble and disassemble. The materials are reusable, saving resources and costs.

[0058] The foregoing description is merely a preferred embodiment of the utility model and is not intended to limit the utility model. All modifications, equivalents, and improvements that are consistent with and within the scope of the principles of the utility model shall be included within the scope of the utility model.
