[0002] During the construction of high-rise buildings, ventilation shafts are used for smoke exhaust and ventilation in the public parts of each floor. Since the traditional brick shafts have poor sealing properties and cannot guarantee the normal air supply and exhaust volume of the floors, vertical air ducts are usually added to the ventilation shafts. The ventilation shafts are mostly arranged in the main part of the high-rise building, and the main part is mostly a concrete shear wall structure. Therefore, most ventilation shafts have one or more sides close to the concrete shear wall, resulting in a narrow distance between the vertical air duct and the concrete shear wall. The width of the narrow space is only 100mm, resulting in multiple clips on the common plate flange between two adjacent sections of the vertical air duct cannot be installed normally, and the standardized installation distance between the two adjacent clips cannot be guaranteed, thereby failing to ensure the tightness of the vertical air duct; a tool and method for quickly installing the common plate flange clips of the vertical air duct in a narrow space should be provided.

[0034] In the present embodiment, at least two assembled support frames connected in sequence are provided, and the assembled support frames include a sleeve-type bracket 5, a core shaft bracket 6 and a U-shaped clamping seat 7. In actual use, the number of assembled support frames can be selected according to the specifications of the vertical air duct 11 and the number of buckles 8 to be installed. The sleeve-type bracket 5 and the core shaft bracket 6 are locked by a spring pin 9, the structure is stable, and it is easy to disassemble and adjust, and the use effect is good.

[0035] In this embodiment, by installing a U-shaped clamping seat 7 on the core shaft bracket 6, and providing a magnetic magnet 7-4 on the U-shaped clamping seat 7, in actual use, under the limiting effect of the U-shaped clamping seat 7 and the magnetic effect of the magnetic magnet 7-4, the buckle 8 can be stably and reliably magnetically attracted to the U-shaped clamping seat 7, so that the buckle 8 can be safely and reliably moved or rotated using the quick installation tool.

[0036] In this embodiment, a support plate 1 is installed at one end of the assembled support frame, and two parallel connecting rods 4, a main handle 2 and an auxiliary handle 3 are provided on the support plate 1. During actual installation, the connecting rod 4 and the sleeve bracket 5 are locked by a spring pin 9, and the support plate 1, the connecting rod 4, the main handle 2 and the auxiliary handle 3 constitute a support structure that is easy to disassemble and assemble with the assembled support frame. It should be noted that when the installation space around the concrete shear wall 10 and the vertical air duct 11 is sufficient, the number of support structures can be two, that is, support structures are provided at both ends of at least two assembled support frames connected in sequence. During actual use, the operator holds the main handle 2 and the auxiliary handle 3 with both hands, and sends the buckle 8 to be installed into the narrow space between the concrete shear wall 10 and the vertical air duct 11 through the U-shaped clamping seat 7 of the assembled support frame, rotates the main handle 2 and the auxiliary handle 3, and the assembled support frame and the U-shaped clamping seat 7 drive the buckle 8 to be installed to be clamped on the common plate flange 12.

[0037] like Figure 1 , Figure 2 and Figure 3 As shown, in this embodiment, the sleeve-type bracket 5 includes two sleeves 5-1 arranged in parallel and a connecting block 5-2 connected between the two sleeves 5-1, the mandrel-type bracket 6 includes two mandrels 6-1 arranged in parallel and coaxially with the two sleeves 5-1 respectively, and a fixing block 6-2 connected between the two mandrels 6-1, one end of the connecting rod 4 and both ends of the mandrel 6-1 are provided with spring pins 9, and both ends of the sleeve 5-1 are provided with mounting holes for the spring pins 9 to pass through.

[0038] In this embodiment, the U-shaped card-mounting seat 7 is fixedly installed on the fixing block 6 - 2 , and the U-shaped card-mounting seat 7 is installed on both side surfaces of the fixing block 6 - 2 .

[0039] In this embodiment, the sleeve-type bracket 5 includes two sleeves 5-1 and a connecting block 5-2, and the mandrel-type bracket 6 includes two mandrels 6-1 and a fixing block 6-2. In actual use, the two sleeves 5-1 can enhance the rigidity and stability of the sleeve-type bracket 5, and the two mandrels 6-1 can enhance the rigidity and stability of the mandrel-type bracket 6. During use in the cantilever state, the sleeve-type bracket 5 and the mandrel-type bracket 6 can be prevented from bending and deforming.

[0040] In this embodiment, by installing U-shaped snap-in seats 7 on both sides of the fixed block 6-2, that is, by increasing the number of U-shaped snap-in seats 7, the operability of the quick installation tool can be improved, and the operator can select the U-shaped snap-in seat 7 located on any side of the fixed block 6-2 to install the snap-in 8 according to the snap-in direction and the snap-in state of the snap-in 8.

[0041] like Figure 2 and Figure 3 As shown, in this embodiment, there is a first angle between the first side plate 7-1 of the U-shaped card mount 7 and the bottom plate 7-3 of the U-shaped card mount 7, and the value range of the first angle is 40° to 50°. There is a second angle between the second side plate 7-2 of the U-shaped card mount 7 and the bottom plate 7-3 of the U-shaped card mount 7, and the value range of the second angle is 120° to 140°.

[0042] In actual use, the magnetic magnet 7-4 is arranged on the bottom plate 7-3 of the U-shaped card seat 7. When there is a first angle between the first side plate 7-1 and the bottom plate 7-3, and the value range of the first angle is 40°~50°, in the process of the U-shaped card seat 7 driving the buckle 8 to flip, the first side plate 7-1 can play a role of auxiliary support for the buckle 8, and can prevent the buckle 8 from accidentally falling off the U-shaped card seat 7. When there is a second angle between the second side plate 7-2 and the bottom plate 7-3, and the value range of the second angle is 120°~140°, it can be ensured that after the buckle 8 is flipped and installed in place, the operator relies on manually overcoming the magnetic attraction between the U-shaped card seat 7 and the buckle 8, so that the U-shaped card seat 7 falls off the buckle 8.

[0043] In this embodiment, the axis of the main handle 2 is parallel to the axis of the sleeve 5 - 1 , and the axis of the auxiliary handle 3 is perpendicular to the axis of the sleeve 5 - 1 .

[0044] In this embodiment, both the main handle 2 and the auxiliary handle 3 are provided with anti-slip rubber sleeves.

[0048] Step 3: Use the quick installation tool to quickly install at least two buckles 8 at the same time:

[0049] When the clamping state of the buckle 8 after installation is as follows: the short-side bending plate 8-1 is located on the bottom surface of the common plate flange 12 of the lower layer, and the long-side bending plate 8-2 is pressed against the top surface of the common plate flange 12 of the upper layer, the specific operation process is as follows:

[0050] Step 301, holding the main handle 2 and the auxiliary handle 3 of the quick installation tool, and using at least two assembled support frames to simultaneously send at least two of the clips 8 to be installed into the narrow space between the concrete shear wall 10 and the vertical air duct 11, so that the first side plate 7-1 of the U-shaped clip seat 7 is located on the side close to the common plate flange 12, and the short side bent plates 8-1 of at least two of the clips 8 are both in contact with the bottom surface of the common plate flange 12 located at the lower layer;

[0051] Step 302: rotate the main handle 2 and the auxiliary handle 3 of the quick installation tool, and use at least two assembled support frames to simultaneously flip over at least two buckles 8 to be installed, so that the long side bending plates 8-2 of at least two buckles 8 are pressed tightly against the top surface of the common plate flange 12 located on the upper layer;

[0052] When the clamping state of the buckle 8 after installation is as follows: the long-side bending plate 8-2 is located on the bottom surface of the common plate flange 12 of the lower layer, and the short-side bending plate 8-1 is pressed against the top surface of the common plate flange 12 of the upper layer, the specific operation process is as follows:

[0053] Step A, holding the main handle 2 and the auxiliary handle 3 of the quick installation tool, and using at least two assembled support frames to simultaneously send at least two of the clips 8 to be installed into the narrow space between the concrete shear wall 10 and the vertical air duct 11, so that the second side plate 7-2 of the U-shaped clip seat 7 is located on the side close to the common plate flange 12, and the long side bent plates 8-2 of at least two of the clips 8 are both in contact with the bottom surface of the common plate flange 12 located at the lower layer;

[0054] Step B, rotate the main handle 2 and the auxiliary handle 3 of the quick installation tool, and use at least two assembled support frames to flip over at least two of the buckles 8 to be installed at the same time, so that the short side bending plates 8-1 of at least two of the buckles 8 are pressed against the top surface of the common plate flange 12 located on the upper layer.

[0055] During actual construction, the method of using the quick installation tool is adjusted according to the clamping state of the buckle 8 located on one side of the common plate flange 12. The operation is flexible, and the connection quality and sealing degree of the vertical air duct 11 can be improved, which saves time and labor, helps to improve construction efficiency, and facilitates promotion and application.
