Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.
As shown in fig. 1 and 3, in one embodiment, there is provided a vertical concrete masonry air duct installation method, the method comprising:
building a next floor steel bar structure on the basis of the floor concrete wall 10, wherein one side of the floor concrete wall 10 is provided with a floor wind pipe section 30;
after the construction of the steel bar structure of the next floor is finished, butting the wind pipe section 40 of the next floor to the wind pipe section 30 of the floor;
and after the next floor wind pipe section 40 is in butt joint with the local floor wind pipe section 30, pouring concrete into the next floor steel bar structure to form the next floor concrete wall 20.

And furthermore, by adopting the method for installing the air pipe in the vertical concrete civil engineering, the actual utilization rate of the building area can be effectively improved.
Of course, the installation of the wind pipe section 30 on the floor can also be performed before the concrete is poured into the steel bar structure on the floor. That is, after the floor reinforcing structure is completely set, the floor air duct section 30 is fixedly installed on one side of the floor reinforcing structure, and at this time, an operation space can be used as an operation space by means of a gap in the floor reinforcing structure, and it is not necessary to additionally reserve an operation space between the floor air duct section 30 and the floor reinforcing structure.
Therefore, when the concrete wall body of the first floor is built, the air pipe section with the height of the first floor is arranged, and when the vertical concrete civil engineering of the whole floor is built, the whole air pipe is installed correspondingly.
Specifically, the next floor in the present application is referred to as the floor, and the next floor refers to a floor constructed on the basis of the floor during construction, and spatially, the next floor is actually located above the floor. For example, as shown in fig. 5, if the current floor is a first floor 60, the next floor is a second floor 70.
It should be further noted that, as shown in fig. 3, an end of the local floor wind pipe segment 30, which is used for being abutted to the next floor wind pipe segment 40, is located above a next floor, that is, an end of the local floor wind pipe segment 30, which is used for being abutted to the next floor wind pipe segment 40, is exposed at a height corresponding to the next floor steel bar structure. Therefore, when the wind pipe section 40 of the next floor is butted with the wind pipe section 30 of the current floor, construction can be carried out by using a gap in the steel bar structure of the next floor as an operation space.
Similarly, as shown in fig. 3, it is assumed that the steel bar structure of the next floor built on the basis of the concrete wall 20 of the next floor is a steel bar structure of the next floor. When the next floor wind pipe segment 40 is butted to the local floor wind pipe segment 30, one end of the next floor wind pipe segment 40, which is far away from the local floor wind pipe segment 30, is located above the next floor slab 23, that is, one end of the next floor wind pipe segment 40, which is far away from the local floor wind pipe segment 30, is exposed at a height corresponding to the steel bar structure of the next floor.
In other words, as shown in fig. 5, the top end of the wind pipe section corresponding to the first floor 60 is located above the second floor 71, the top end of the wind pipe section corresponding to the second floor 70 is located above the third floor 81, and the top end of the wind pipe section corresponding to the third floor 80 is located above the fourth floor.
Further, in order to ensure reliable butt joint and sealing between the next floor wind pipe section 40 and the local floor wind pipe section 30, the next floor wind pipe section 40 and the local floor wind pipe section 30 can be locked together in a riveting manner. In the process, all the peripheries of the next floor air pipe sections 40 need to be riveted, when the installation method in the vertical concrete construction is adopted for implementing installation, construction operation can be carried out by taking gaps in the next floor steel bar structure as an operation space, and therefore all the peripheries of the next floor air pipe sections 40 can be operated during riveting.

When the next floor wind pipe section 40 and the floor wind pipe section 30 are butted, the periphery of the joint part needs to be connected by the first connecting piece, so that construction needs to be carried out on one side of the next floor wind pipe section 40 facing the next floor steel bar structure. At this time, based on that concrete is not poured in the next floor steel bar structure, the wide gap in the next floor steel bar structure is enough for an operator to construct and install the first connecting piece.
Further specifically, in one embodiment, the first connecting member includes a plurality of rivets. And a first flange is arranged at one end of the next floor wind pipe section 40, which is butted with the current floor wind pipe section 30. And a second flange is arranged at one end of the wind pipe section 30 of the current floor, which is butted with the wind pipe section 40 of the next floor. The first flange with the circumference of second flange all is equipped with a plurality of mounting through-holes, the rivet will through passing in proper order mounting through-hole on the first flange with mounting through-hole on the second flange first flange with the second flange connection is fixed. The rivets are arranged at intervals along the circumferential direction of the first flange.
In the actual construction process, the wind pipe section 40 of the next floor can be lifted, the first flange and the second flange are aligned together, and then the rivets are sequentially locked in the mounting through holes.
Further, in one embodiment, as shown in fig. 3, the next-floor duct section 40 includes a multi-sub-duct 41. Before the next floor wind pipe section 40 is butted on the local floor wind pipe section 30, the method further comprises the following steps:
and a plurality of sub-air pipes 41 are connected in a butt joint mode to form the next floor air pipe section 40.

And then the wind pipe section 40 of the next floor is hoisted and butted to the wind pipe section 30 of the current floor.
For example, if the length of the wind pipe section 30 of the current floor is greater than the height of the current floor, even if the height of the wind pipe section 40 of the next floor is consistent with the height of the next floor, the top end face of the wind pipe section 40 of the next floor after installation is higher than the concrete wall 20 of the next floor.
