Description

Technical Field

[0001] The utility model belongs to the technical field of road-spanning construction, and in particular relates to a safety protection hanging shed with a bottom-covering hanging basket for road-spanning construction. Background Art

[0002] With the increase of investment in infrastructure construction in my country, highway construction is changing with each passing day, especially involving more and more bridge and cross-line construction. When using hanging basket to construct cast-in-place beams, in order to prevent construction tools and materials from falling from heights and injuring pedestrians and passing vehicles on the ground, a safety protection scaffolding is usually set up in the area below the cast-in-place beam being constructed.

[0003] The existing patent (Announcement No.: CN212835008U) discloses an attached fully enclosed safety protection shed for the construction of a hanging basket across a highway, which belongs to the technical field of hanging basket protection devices and solves the problems of the existing ground-type protection sheds, such as long construction period, high cost, and difficulty in disassembly and inability to be reused. The patent includes a hanging basket, a bottom tray, a first bearing, and a first threaded pipe. The first threaded pipe is threadedly connected to the surface of the screw, and a nut is threadedly connected to the surface of the screw. Through the bottom tray, the first bearing, the first threaded pipe and the screw, it is convenient for the staff to disassemble the bottom tray; through the knob, the threaded column and other components, the staff can disassemble the embedded seat in the protection frame for secondary use.

[0004] The above prior art often has the following problems when used:

[0005] When the above device is used, the screw rod and the first threaded tube are manually adjusted to connect or disassemble the hanging basket and the bottom tray. In such a large-scale project, it is laborious and inconvenient to manually twist the first threaded rod for connection and disassembly, which also affects the construction efficiency.

[0006] When the above device is in use, the protective frame is fixed. The specific construction parameters of the cross-road construction will vary according to the road conditions and geographical location. The height and thickness of the constructed bridge will be different. To ensure safety, no matter how high and thick the construction bridge is, the height of the protective frame on both sides of the bridge should always exceed the bridge height within a certain range. Therefore, the use range of the fixed protective frame is relatively small. If the protective frame is customized according to the bridge height above different roads, the construction cost will increase accordingly and the practicality will be low. Utility Model Content

[0007] In view of the deficiencies in the prior art, the utility model provides a safety protection hanging shed with a bottom-covering hanging basket for cross-road construction.

[0031] Combined with the actual construction situation of the K65+767 Ji-Guang Expressway separated overpass construction of the S244 project, the K65+767.3 Ji-Guang Expressway Bridge is 299 meters long, and the main span across the G35 Ji-Guang Expressway is 70 meters long. The project department, in conjunction with a qualified company, designed and verified the hanging basket bottom safety protection shed based on the project characteristics. The design scheme of the hanging basket bottom safety protection shed was verified by experts. The main piers under construction are 5# and 6#, of which 6# pier will be constructed first and 5# pier will be constructed later.

[0032] After the tensioning of Pier 6# was completed on March 22, 2022, the assembly of the hanging basket and the bottom safety protection of the hanging basket began simultaneously, and the installation was completed on April 1, 2022, taking 10 days to complete the installation of the hanging basket and the bottom safety protection; the demolition work began on September 10, 2022, and on September 17, 2022, it took 7 days to complete the demolition of the left and right hanging baskets and bottom safety protection of Pier 6#.

The hanging basket and bottom safety protection of Pier 5# were successively dismantled from October 10 to 11, 2022, which took 7 to 8 days.

[0034] During the use of the hanging basket bottom safety protection, it was found that the hanging basket bottom safety protection is easy to install and dismantle, requires less consumables, has low cost, is easy to use, and has little impact on the highway. It has achieved the results of fast cast-in-place construction of the bridge box girder, low investment, excellent quality and good safety.

[0035] The functional principle of the utility model can be explained through the following operation modes:

[0036] When in use, the staff uses an electric torque gun to remove or install the first high-strength bolt 10 and the second high-strength bolt 11 on the bracket 5, folds or unfolds the No. 1 protective plate 8 and the No. 2 protective plate 9, and at the same time removes or installs the bottom plate 4 by adjusting the high-strength bolts on the bottom of the hanging basket 2, saving a lot of time before and after construction, improving construction efficiency and reducing construction costs.

The second bevel gear 18 drives the first bevel gear 16 and the screw 15 to rotate. Since the screw 15 is threadedly matched with the threaded hole in the telescopic plate 13, the lifting and lowering of the telescopic plate 13 can be controlled. When encountering different construction conditions, the top of the telescopic plate 13 in the No. 2 protective plate 9 can be extended to a certain distance from the top surface of the bridge, thereby improving the application range of the device and further reducing the construction cost of customized protective frames.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it.
