Background

The protective shed is a horizontal protective facility which is usually arranged in the high-rise building construction for preventing falling objects, and the width of the protective shed is usually between 4 and 6 m. Generally, with the continuous rise of building height, need every certain high back of interval, set up a protection canopy of encorbelmenting outward. The protection network mode of setting up of encorbelmenting is pre-buried good built-in fitting on the floor, and steel pipe one end is encorbelmented, and the steel pipe other end is connected with the built-in fitting, sets up the protection canopy support body at the section of encorbelmenting of steel pipe, and it forms to seal to pull up pocket net last, however, this kind of mode of setting up has a great deal of limitation. For example: the longer the cantilever length is, the more floors can be covered, the larger the cantilever distance is due to the use of steel pipes, so that the bearing capacity requirement of the common steel pipes is difficult to meet, the distance between the upper part and the lower part of the cantilever protection shed is small, and the material consumption is increased; secondly, the positioning requirement of the embedded part is high, and the setting of a protective net is influenced by overlarge deviation; and thirdly, the protection shed with the adjacent height needs to be dismantled, and the material of the protection shed is used for erecting the protection shed on the upper layer, so that the erection construction is time-consuming and labor-consuming.

Consequently, a large amount of integral type protection networks of encorbelmenting outward have appeared among the prior art, realize accomplishing to assemble on ground, wholly suspend in midair again to upstairs installation in midair, realize integral installation and demolish construction operation, reduce constructor's danger coefficient. For example: patent No. 202121727575.5 discloses a promotion formula protection network of encorbelmenting outward, including the protection network body, lower connecting piece and last connecting piece, the protection network body includes the frame, connect the rope, it sets up on the frame to connect rope one end, be equipped with the net subassembly on the frame, lower connecting piece is used for installing on the building, be formed with connecting portion between lower connecting piece and the building or on the connecting piece down, connecting portion one end opening, connecting portion and frame looks adaptation, connecting portion are used for the location frame, it is used for installing on the building to go up the connecting piece, go up the connecting piece and be used for connecting the connection rope, through setting up connecting portion, the one end of frame is gone into the realization location in the connecting portion from the opening card, the other end of frame is through connecting the rope and connecting the connecting piece of connection, the protection network body fixed column under the action of gravity, the protection network body has been hoisted, the frame can conveniently break away from connecting portion from the opening, be convenient for install and remove the promotion formula.

For another example: patent application No. 201911258558.9 discloses an angle-adjustable assembly type horizontal cantilever protective shed and a construction method thereof, comprising a protective shed frame, wherein one side of the protective shed frame is hinged with a steel frame column through a connecting piece, the other side of the protective shed frame is connected with the steel frame column through a steel wire connecting rope, one end of the steel wire connecting rope is connected with the outer side of the protective shed frame, the other end is connected with the steel frame column above the connecting piece, more than two steel bar rings are arranged on the outer side of the protective shed frame, the steel bar rings are welded on the protective shed frame, a steel wire connecting rope is connected in each steel bar ring in a penetrating way, the steel frame column is provided with a pull ring at the position connected with the connecting rope, one end of the steel wire connecting rope is connected with the steel bar circular ring in a penetrating way, and the other end of the steel wire connecting rope is fixed on the pull ring.

For another example: patent No. 201610674579.9 discloses an assembly type high altitude shelter for building construction and its assembly method, which is used for assembling on three floors including upper floor, middle floor and lower floor, and is located outside each floor, and comprises a plurality of cantilever beams fixed on the lower floor, the part of each cantilever beam extending out of the lower floor is fixed with the outer edge of the middle floor through an outer frame unloading steel wire rope, and an outer scaffold is installed on the upper surface of each cantilever beam, a fixed beam is installed on the cantilever end of each cantilever beam, a plurality of fixed supports are installed on the fixed beam at intervals, the lower end of the protection net is rotatably connected with each fixed support, the upper end is fixed with the outer edge of the upper floor through a plurality of inclined steel wire ropes, the protection net is inclined to the horizontal plane to form an acute angle under the traction of the inclined steel wire ropes, and has the advantages of convenient and rapid assembly, reusable turnover, low danger in the assembly process, and can ensure the complete construction, the practicability is strong and the like.

It is thus clear that prior art sets up the singleness about the structural function of high-rise building protection canopy, is difficult to satisfy interim demand and adjusts protection canopy extension length, and protection canopy sets up the distance between the two-layer about the extension then, and the adjustment protection canopy rotation angle of being more not convenient for leads to being difficult to satisfy the regulation protection canopy and protects the radius. Based on this, this researcher combines to engage in high-rise building construction protection operation practice for a long time, provides new structure for the protection canopy.
