[0052] The device is attached to the building outer wall 6 and the construction hanging basket 8, wherein the expansion bolt 1 is fixed in the structural layer of the building outer wall 6, the expansion bolt 1 is hung with an electric hoist 2, a hook 7 is pulled by a wire rope under the electric hoist 2, and a slag collection bag 9 is hung on the hook 7. The slag feeding hopper 4 is close to the wall, a baffle plate 3 is installed on the top, the feeding hopper is placed in the feeding hopper frame 5, and the feeding hopper frame 5 is connected to the construction hanging basket 8.

[0053] refer to Figure 2 As shown, when the facade demolition operation is being carried out, the construction slag generated by the demolition flows along the baffle plate 3 into the construction slag feeding hopper 4, and then the construction slag slides along the inner wall of the feeding hopper to the lower opening and enters the construction slag collecting bag 9. When the construction slag collecting bag collects a certain amount of construction slag, the electric hoist 2 is started to make the wire rope traction hook 7 move toward the ground, and finally the construction slag collecting bag 9 is transported to the ground, and then the construction slag in the construction slag collecting bag is emptied. Then the hook 7 is pulled upward by the electric hoist, and when the hook 7 rises to the limit plate 10, it stops rising. At this time, the construction slag collecting bag 9 is inserted into the lower opening of the construction slag feeding hopper 4, and the next round of collection work can be started.

[0054] Figure 3As shown, the hopper frame 5 includes an upper transverse frame 501, an oblique support 502, a limit plate 10 and a lower transverse frame 503.

The four corners of the upper transverse frame are respectively connected to the four corresponding corners of the lower transverse frame through oblique supports 502, and the four oblique supports are of equal length, so that the connecting line of the geometric center lines of the upper and lower transverse frames is located on the same plumb line. A limit plate 10 is also installed between two adjacent oblique supports on the front of the hopper frame to keep a preset distance between the hopper frame 5 and the building exterior wall 6. The limit plate 10 is placed horizontally, and the limit plate 10 is provided with a flexible cushion layer on the edge facing the building exterior wall 6 to avoid damaging the building exterior wall.

A plurality of baffle plates 3 are also installed on a long side of the top of the device, and the baffle plates 3 are connected to the hopper through a loose-leaf structure, so that the baffle plates 3 can rotate with the long side of the hopper as the axis. Baffle plate gaskets 11 are also installed on the side of the baffle plate 3, and the baffle plate gaskets 11 are in flexible contact with the facade when the device is working normally. Rubber expansion belts 12 are also connected between adjacent baffle plates. When adjacent baffle plates are not located on the same plane, the rubber expansion belts can be stretched so that there is no gap between the two baffle plates. A long strip rope hole 13 is opened at the center of the baffle plate located in the middle, and the wire rope pulled down by the electric hoist 2 passes through the hole.

[0057] refer to Figure 6 As shown, the expansion bolt includes: a screw rod 102 , a push nut 104 , a sleeve 106 , a lower wedge block 107 and an upper wedge block 108 .

[0058] A push nut 104 is provided in the middle of the screw rod 102, and the sleeve 106 is sleeved on the screw rod 102, and the sleeve 106 is fixedly connected to the push nut 104; the lower wedge block 107 is provided on the other side of the sleeve 106, and is in contact with the sleeve 106, and the lower wedge block 107 is provided with a groove, and the screw rod 102 is arranged in the groove body of the lower wedge block 107; a spring 105 is also sleeved on the outer side of the sleeve 106, and the two ends of the spring 105 are respectively connected to the lower wedge block 107 and the push nut 104; an upper wedge block 108 is provided on the other side of the lower wedge block 107, and the wedge-shaped inclined surfaces of the upper wedge block 108 and the lower wedge block 107 are matched, and the upper wedge block 108 is fixedly connected to the screw rod 102.

[0059] Preferably, when the expansion bolt is fixed, the upper wedge block 108 and the lower wedge block 107 are located in the wall hole 109, and the push nut 104 is configured to be screwed in the direction of the upper wedge block 108. When the expansion bolt is removed, the push nut 104 is configured to be screwed away from the upper wedge block 108.

[0060] Preferably, a locking nut 103 is further provided in the middle of the screw rod 102 , and when the expansion bolt is fixed, the locking nut 103 and the push nut 104 are in contact with each other.

[0061] Preferably, the screw rod 102 is further provided with a nut 101 , which is located on a side of the locking nut 103 away from the push nut 104 .

[0062] Preferably, the outer surfaces of the lower wedge block 107 and the upper wedge block 108 are provided with corrugated ridge structures, and the connection tightness between the expansion bolt and the wall is improved by providing the ridge structures.

[0063] Preferably, the upper wedge block 108 is connected to the screw rod 102 by integral molding or welding. Preferably, two ends of the spring 105 are respectively connected to the lower wedge block 107 and the push nut 104 by welding.

[0064] The working principle of this detachable expansion bolt:

[0065] (1) When the expansion bolt is in the initial state, the lower wedge block 107 and the upper wedge block 108 are in a separated state, and the spring 105 is in a natural state.

[0066] (2) After the bolt penetrates into the hole in the wall, the push nut 104 is rotated inward, and the push nut 104 pushes the sleeve 106 so that it has a tendency to move deeper into the hole. After the push nut 104 contacts the wall, the screw rod 102 moves outward, so that the lower wedge block 107 and the upper wedge block 108 at the end of the screw rod move toward each other. After the lower wedge block 107 and the upper wedge block 108 begin to contact, the lower wedge block 107 begins to move outward along the radial direction of the screw rod 102 due to the action of the wedge surface. After the lower wedge block 107 contacts the hole wall, the push nut 104 is screwed in 3-5 mm. At this time, the lower wedge block 107 and the upper wedge block 108 have a tightening effect on the hole wall, and then the locking nut 103 is screwed to a position close to the push nut 104, completing the fixing of the bolt to the wall.

[0067] (3) When the exterior work is completed and the bolts need to be removed, the locking nut 103 is first screwed outward for a distance, and then the push nut 104 is screwed outward. At this time, the sleeve 106 moves outward of the hole under the drive of the push nut 104 and separates from the lower wedge block 107. The spring 105 is in a stretched state and starts to pull the lower wedge block 107 outward of the hole. The push nut 104 is screwed outward continuously to separate the lower wedge block from the hole wall, and then the bolt is removed from the hole in the wall as a whole, completing the removal of the bolt.

[0068] When installing the construction slag collection device of the present application, first drill a hole on the outer wall, fix the expansion bolt 1 in the hole of the outer wall, and hang the electric hoist 2 on the screw 102 on the expansion bolt 1. At the same time, first install the baffle plate 3 on the top of the construction slag hopper 4 on the ground, and install the limit plate 10 on the hopper frame 5, and then install the hopper frame 5 on the front of the construction hanging basket 8, and then lift the construction hanging basket 8 and the hopper frame 5 as a whole to the height of the outer wall working surface. Then hang the construction slag hopper 4 into the hopper frame 5, and then pass the pull rope under the electric hoist 2 through the pull rope hole 13 and the limit plate 10 on the baffle plate 3, and install the hook 7 at the bottom of the pull rope, and then hang the construction slag collection bag 9 on the hook 7.

[0069] When disassembling the device, first remove the slag collection bag 9 and the hook 7 in sequence, pull out the pull rope from the limit plate 10 and the pull rope hole 13, and then remove the electric hoist 2. Then pull out the slag feeding hopper 4 from the feeding hopper frame 5 and hang it on the ground, and then lower the construction hanging basket 8 and the feeding hopper frame 5 as a whole to the ground. Finally, take out the expansion bolt 1 from the hole in the outer wall to complete the disassembly of the device.
