Problems solved by technology

In addition, the continuous compression of the area of ​​the mechanical and electrical functional pipe wells in super high-rise buildings makes the operable space between the pipe wells extremely tight. If the wall of the pipe well is a shear wall, the method of building the pipe well after the pipe installation is completed It is also impossible. It has become a difficult problem for the connection of the flange of the air duct, the subsequent insulation of the air duct, and the sealing of the floor.

Embodiment 1

[0034] In view of the low efficiency of installing air ducts in the prior art, cumbersome procedures, and time-consuming and labor-intensive installation of the narrow structure of the air shaft, this embodiment is optimized to solve the problems existing in the prior art.

[0035] Specifically, such as figure 1 As shown, this embodiment provides a device for installing air ducts in narrow shafts, including a main bracket, which is arranged at the air duct well and is connected and fixed with the inner wall and the ground of the building; the main bracket is provided with a lifting Device 3, the hoisting device 3 is connected to the hoop device 7 through the hoisting cable 6, and the hoop device 7 is used to hold the upper port of the air duct section tightly and drive the air duct section up and down under the action of the hoisting device 3; the hoop device 7 includes a set of holding side bars 701 oppositely arranged, and at least two pair of tie rods 702 for adjusting the ...

Embodiment 2

[0045] This embodiment discloses a device for installing an air duct in a narrow shaft. The difference from Embodiment 1 is that this embodiment optimizes the top beam structure.

[0046] Specifically, such as Figure 4 As shown, the present embodiment adopts another kind of feasible roof beam structure 2: the roof beam structure 2 is a U-shaped beam structure, the middle part of the U-shaped beam is connected and fixed with the column 1, and the two ends of the U-shaped beam are connected with the column 1. Internal wall connections are fixed. When such a solution is adopted, the U-shaped beam structure has two supporting structures, both of which can be used to install the lifting device 3 to increase the lifting force. If the two lifting devices 3 are installed together for lifting, the stability and safety of the lifting can be effectively improved sex.

[0047] Other structural components not mentioned in this embodiment are the same as those in Embodiment 1, and will n...

Embodiment 3

[0049] The content of the above-mentioned embodiment 1 describes the hoisting device, and this embodiment discloses the corresponding hoisting method, which is now described as follows:

[0050] Such as Figure 5 As shown, a hoisting method for the installation of air ducts in narrow shafts, including:

[0051] S01: Assemble and connect the air duct section into an air duct section, and move the air duct section to the air shaft, and complete the installation of the bottommost air duct section;

[0052] S02: Install the upper and lower sections of the air duct at the air shaft of each floor, and install them layer by layer from the bottom to the top; connect the hoop device with the upper section of the air duct on this floor, and use the lifting device to lift the floor The upper section of the air duct is hoisted into the air shaft;

[0053] S03: Use the lifting device to lift the upper air duct section of the floor to a certain distance, and at the same time put the lower...

Abstract

The invention relates to the technical field of building construction, in particular to a device for installing an air pipe in a narrow vertical shaft and a hoisting method. The device comprises a main support, and the main support is arranged at an air pipe well and fixedly connected with an inner wall of a building and the ground; a lifting device is arranged on the main support, the lifting device is connected with a hoop device through a lifting cable, and the hoop device is used for tightly holding an upper end opening of an air pipe joint and driving the air pipe joint to ascend and descend under the action of the lifting device; and the hoop device comprises a set of holding edge strips which are oppositely arranged, and at least two opposite pull rods used for adjusting the relative distance of the holding edge strips are arranged on the holding edge strips. The lower end of the lifting cable is connected with the holding edge strips. An air pipe section is lifted and dropped back through the lifting device, an upper-section air pipe and a lower-section air pipe are connected, and the problem that installation is inconvenient in the narrow space of the air well is solved; and meanwhile, the multiple sections of air pipes are assembled into the air pipe section in advance, then hoisting installation is conducted, and the installation efficiency and reliability of the air pipe are greatly improved.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a device and a hoisting method for installing an air duct in a narrow shaft. Background technique [0002] In high-rise buildings, it is necessary to set up a special air duct structure for ventilation. According to engineering experience, the air duct made of concrete has a large loss of air volume along the way, which will easily lead to the failure of the mechanical smoke control system; in engineering practice, the smoothness of the air duct plays a key role in the effectiveness of the system. Therefore, the mechanical pressurized air supply system and the mechanical smoke exhaust system should use pipes to supply air, and neither of them should use civil air ducts. The air supply (smoke exhaust) pipes should be made of non-combustible materials with smooth inner walls. In addition, the continuous compression of the area of ​​mechanical and electrical function ...
