[0001] The invention relates to a method for preventing falling objects before the construction of a building flue, and belongs to the technical field of building construction. Background Art

[0002] When constructing a high-rise building, in order to achieve uniform smoke exhaust, a flue must be reserved during the pouring of the building, and the flue will be uniformly constructed after the pouring of the building is completed. Therefore, before the flue is constructed, a flue hole that needs to be protected will appear on the floor.

[0003] The existing floor hole protection technology is shown in Chinese Patent Publication No. CN209686908U. Although protection can be achieved by installing a cover plate at the hole on the floor through a support rod, when there is construction work on the upper floor, large pieces of solidified concrete will fall down from the unprotected flue holes on the upper layer and hit the cover plate, scattering and rolling down randomly, affecting the safety of on-site workers when walking during construction. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a method for preventing falling objects before the construction of a building flue.

[0007] The method comprises: constructing a protective structure for preventing falling objects on the building body on the lower floor before the construction of the building body flue, and when the building body on the upper floor is under construction, solidified concrete falls from the flue hole of the upper floor building, and when the solidified concrete falls to the receiving net, the receiving net in an inclined state catches the large pieces of solidified concrete;

[0008] The solidified concrete is collected at the bottom edge of the inclined receiving net, and the discharge cover on the receiving net is opened to discharge and collect the collected solidified concrete.

[0009] The protective structure for preventing falling objects before the construction of the building flue includes:

[0010] The vertical pipe installed at the flue hole;

[0011] A receiving net in an inclined state is fixedly installed on the vertical pipe.

[0012] The utility model also comprises a clamping plate which is clamped on the inner side of the flue hole, and the vertical pipe is fixed on the clamping plate.

[0013] The clamping plates are four and are correspondingly clamped and installed at the four corners of the flue hole; and vertical pipes are fixed on the four clamping plates.

[0014] It also includes a building with a flue hole, and the corresponding clamping plate is tightly installed in the inner side of the flue hole through a threaded telescopic rod.

[0015] The side and bottom edges of the receiving net are fixed with ribs, a discharge port is arranged on the receiving net, and a discharge cover plate is rotatably hingedly connected to the receiving net at the discharge port, and the discharge cover plate is at the lowest point of the receiving net in an inclined state.

[0016] The card plate is provided with a slide groove, in which a blocking cover plate is slidably installed forward and backward, and the blocking cover plate covers the flue hole of the building body.

[0017] The left and right sides of the blocking cover plate are rotatably hinged with gap cover plates through hinges, and the gap cover plates are tangent to the clamping plate.

[0020] Figure 2 The structure of the present invention is schematically shown in FIG. Figure 2 ;

[0021] In the figure: 1-building; 11-flue hole; 12-threaded telescopic rod; 2-card; 21-blocking cover; 3-vertical pipe; 4-receiving net; 42-discharge cover; 41-side; 22-gap cover. DETAILED DESCRIPTION

[0022] The technical solution of the present invention is further described below, but the scope of protection claimed is not limited to the description.

[0023] like Figure 1 to Figure 2 shown.

[0024] The present application discloses a protective structure for preventing falling objects before the construction of a building flue, comprising:

[0025] The card plate 2 is stuck on the inner side of the flue hole 11, and the card plate 2 is L-shaped. The L-shaped card plate 2 is correspondingly connected and placed on the building 1 at the flue hole 11; there are four card plates 2, and the four card plates 2 are correspondingly connected and placed on the four corners of the rectangular flue hole 11.

[0026] The relative clamping plates 2 are tightly mounted in the inner side of the flue hole 11 through the threaded telescopic rod 12. The four clamping plates 2 are welded and fixed with vertical pipes 3, which are circular steel pipes. The four vertical pipes 3 correspond to the four clamping plates 2.

[0027] The vertical pipe 3 is tied or welded with a receiving net 4 in an inclined state, and the receiving net 4 is a woven mesh or a steel mesh. When the receiving net 4 is formed by a steel mesh, there are ribs 41 on the side and bottom of the receiving net 4, and a discharge port is provided on the receiving net 4. The receiving net 4 at the discharge port can be rotatably hinged with a discharge cover plate 42, and the discharge cover plate 42 is at the lowest point of the receiving net 4 in an inclined state; the discharge cover plate 42 can be rotated to open and the solidified concrete can be discharged uniformly.

[0028] The card plate 2 is provided with a slide groove, in which a blocking cover plate 21 is installed to slide forward and backward. Figure 1 The blocking cover 21 in the middle covers the flue hole 11 of the lower building body 1. Since the blocking cover 21 can slide forward and backward with the card plate 2, there is a gap between the left and right sides of the blocking cover 21 and the flue hole 11. Therefore, the left and right sides of the blocking cover 21 are rotatably hinged with a gap cover 22 through hinges; after the blocking cover 21 slides into place forward and backward, the hinges are connected with the gap cover 22 and the blocking cover 21 using screws, so that the gap cover 22 can be tangent to the card plate 2 front and back to play a limiting role, and at the same time, the gap cover 22 covers the gap between the left and right sides of the blocking cover 21 and the flue hole 11; when the blocking cover 21 slides out, the screws and hinges connecting the gap cover 22 and the blocking cover 21 are removed, and then the blocking cover 21 slides out from the slide groove on the card plate 2.

[0029] The present application discloses a method for preventing falling objects before the construction of a building flue, comprising: constructing a protective structure for preventing falling objects before the construction of the building flue on the lower floor 1, and when the upper floor 1 is under construction, solidified concrete falls from the flue hole 11 of the upper floor 1. At this time, when the solidified concrete falls to the receiving net 4, the receiving net 4 in an inclined state catches large pieces of solidified concrete, and large pieces of solidified concrete that are scattered and released by collision can also be caught by the receiving net 4, and only small particles fall from the receiving net 4 to the blocking cover plate 21, thereby avoiding the situation where solidified concrete is scattered and rolled on the lower floor 1, improving the safety of on-site workers when walking during construction, and solving the problem in the prior art that large pieces of solidified concrete fall and roll randomly, affecting the safety of on-site workers when walking during construction.

[0030] The solidified concrete is collected at the bottom edge of the inclined receiving net 4. Later, the discharge cover 42 on the receiving net 4 is opened to discharge, collect and transport the collected solidified concrete to the fertilizer tank for processing as backfill.
