Summary of the Invention

Problems to be Solved by the Invention

[0004] However, in the method for connecting vertical pipes described in Patent Documents 1 and 2, since the lower vertical pipe is connected while each vertical pipe is lifted, the work at the site takes time, and since the connection is made in an unstable state with the vertical pipe suspended, there is a problem that the workability is poor. In addition, in order to accommodate a plurality of equipment pipes in a narrow PS (pipe space), the vertical pipes such as refrigerant pipes are arranged densely, and improvement of the workability of the connection work is desired.

[0005] Therefore, the present invention has been made in view of the above circumstances, and provides a method for constructing vertical pipes that can be installed efficiently.

Means for Solving the Problems

[0006] In order to achieve the above object, the present invention employs the following means. In other words, the vertical piping installation method according to the present invention comprises a lifting step of lifting a piping unit having a frame and a plurality of vertical pipes extending in the vertical direction fixed inside the frame; a frame connecting step of positioning the lifted piping unit above the piping unit installed on the lower side and connecting the upper part of the frame of the lower piping unit with the lower part of the frame of the upper piping unit; and a vertical piping connecting step of connecting the lower part of the vertical pipes of the upper piping unit with the upper part of the vertical pipes of the lower piping unit.

[0007] In this vertical piping installation method, the piping unit containing multiple vertical pipes is lifted and placed on top of the piping unit installed below, connecting the upper and lower frames. The lower part of the vertical pipes of the upper piping unit is connected to the upper part of the vertical pipes of the lower piping unit. Since multiple vertical pipes can be lifted and installed at once, rather than lifting them one by one, multiple vertical pipes can be installed and connected efficiently.

[0008] Furthermore, the vertical piping installation method according to the present invention may include a positioning step for adjusting the orientation of the lower and upper piping unit frames.

[0009] In this method of constructing vertical piping, a suspended piping unit is placed above the lower piping unit to adjust the orientation of the frames of the upper and lower piping units. By setting the orientation of the frames to a predetermined direction, the orientation of the vertical piping naturally becomes predetermined, making it easy to adjust the orientation of the vertical piping.

[0010] Furthermore, in the vertical piping construction method according to the present invention, the frame may have a plurality of frame members formed in a four-sided frame shape in plan view and arranged spaced apart vertically, and vertical members connecting the upper and lower frame members.

[0011] In this vertical piping construction method, the frame is formed in a four-sided frame shape in plan view, with multiple frame members spaced apart vertically and connected by vertical members. Therefore, since the inside and outside of the frame are in communication, workers can reach their hands from the outside to the inside of the frame to perform tasks such as connecting the vertical pipes, thus improving work efficiency. [Effects of the Invention]

[Figure 8] This figure shows the frame connection step of the vertical piping construction method according to the first embodiment of the present invention. [Modes for carrying out the invention]

[0014] The following describes a method for constructing vertical piping according to one embodiment of the present invention, with reference to the drawings. Figure 1 is a perspective view showing a piping unit installed using a vertical piping construction method. The pipe unit 100 used when installing the pipe 1 will be described. As shown in FIG. 1, the pipe unit 100 has a frame body 2 and a pipe (vertical pipe) 1.

[0015] The outer edge of the frame body 2 is substantially rectangular parallelepiped. The frame body 2 is substantially rectangular in plan view. The frame body 2 has an upper frame (frame member) 21, a lower frame (frame member) 22, an intermediate frame (frame member) 23, and a connecting vertical member (vertical member) 24. Note that the shape of the outer edge of the frame body 2 is not limited to substantially rectangular parallelepiped and can be set as appropriate.

[0016] The upper frame 21, the lower frame 22, and the intermediate frame 23 are square frames. The lower frame 22 is disposed below the upper frame 21. The intermediate frame 23 is disposed midway between the upper frame 21 and the lower frame 22 in the vertical direction. Note that the shapes of the upper frame 21, the lower frame 22, and the intermediate frame 23 can be set as appropriate. The intermediate frame 23 may not be disposed.

[0017] The connecting vertical member 24 extends in the vertical direction. The connecting vertical member 24 connects the four corners of the upper frame 21, the lower frame 22, and the intermediate frame 23 formed in a square frame shape in plan view. Note that as long as the connecting vertical member 24 connects the upper frame 21, the lower frame 22, and the intermediate frame 23, it may be provided at any position on the four sides of the upper frame 21, the lower frame 22, and the intermediate frame 23 instead of being provided at the corners. Also, the connecting vertical member connecting the upper frame 21 and the intermediate frame 23 and the connecting vertical member connecting the intermediate frame 23 and the lower frame 22 may be disposed at different positions in plan view. Further, the upper frame 21 and the intermediate frame 23, and the intermediate frame 23 and the lower frame 22 may be connected by diagonal members inclined with respect to the vertical direction.

[0018] A refractory 40 is provided outside the frame body 2. The refractory 40 is provided on the four outer peripheral surfaces of the frame body 2.

[0019] Inside the upper frame 21, lower frame 22, and intermediate frame 23, connecting members 26 are provided that connect opposing sides of a roughly rectangular shape in plan view. The connecting members 26 and the intermediate frame 23 are provided with positioning parts 41 for positioning the pipe 1 in a predetermined position. The positioning parts 41 may also be provided on the upper frame 21 and lower frame 22.

[0020] Multiple pipes 1 are arranged inside the frame 2. In a plan view, multiple pipes are arranged in both the vertical and horizontal directions of the frame 2. The pipes 1 are supported by positioning parts 41 provided on the frame 2. The pipes 1 extend in the vertical direction. The pipes 1 are, for example, refrigerant pipes, water supply pipes, drainage pipes, etc.

[0021] Figure 2 shows an overview of the vertical piping installation method. Figure 3 shows an overview of the vertical piping installation method and is a diagram of the subsequent steps after Figure 2. Figures 2 and 3 schematically show the piping unit 100. As shown in Figures 2 and 3, a piping space S is formed at the location where the piping 1 is installed, which extends vertically across multiple floors. No flooring materials, columns, beams, or other structural members are placed in the piping space S.

[0022] Let's take the example of installing piping unit 100 on the Nth floor. We will explain the general procedure for installing vertical piping. As shown in Figure 2, before installing pipe 1 on the Nth floor, piping unit 100 (referred to as piping unit 100A) is already installed on the N-1 floor, one floor below the Nth floor. On the Nth floor, the upper part of piping unit 100A protrudes upward from the floor F.

[0023] As shown in Figure 3, piping unit 100 (referred to as piping unit 100B) is installed above piping unit 100A. The height of piping unit 100B is lower than that of piping unit 100A. With piping unit 100B installed above piping unit 100A, the upper end of piping unit 100B is above floor F of the Nth floor and below floor F1 of the N+1th floor.

[0024] Next, the piping unit 100A is lowered towards the Nth floor from the floor opening Fa of the piping space S formed in the floor F1 of the N+1 floor, and the piping unit 100A is installed above the piping unit 100B.

[0025] Figures 4 to 7 show the installation method for vertical piping. Next, we will explain the specific steps involved in the installation of vertical piping.

[0026] (lateral movement process) As shown in Figure 4, a winch mechanism 31 is installed on the underside of floor F2 on the N+2 floor. The location where the winch mechanism 31 is installed is where the floor opening on the N+2 floor is formed. The piping unit 100A to be installed on the N floor is transported to the N+1 floor. The piping unit 100A is laid on its side and transported on a transport device 32 such as a trolley.

[0027] (Lifting process) As shown in Figure 5, the piping unit 100A is attached to the wire of the winch mechanism 31, and the piping unit 100A is lifted and raised upright.

[0028] As shown in Figure 6, the piping unit 100A is placed above the floor opening Fa on the N+1 floor. As shown in Figure 7, the piping unit 100A is lowered from the floor opening Fa to the N floor.

[0029] (Alignment process) As shown in Figure 7, piping unit 100A is placed above piping unit 100B. At this time, piping unit 100B and piping unit 100A are adjusted so that they are in a predetermined position. For example, a spirit level is placed above either the upper frame 21, lower frame 22, or intermediate frame 23 of the frame 2 so that the upper frame 21, lower frame 22, and intermediate frame 23 are aligned with the horizontal plane. By aligning the upper frame 21, lower frame 22, and intermediate frame 23 with the horizontal plane, the piping 1 supported by the frame 2 will be oriented in the vertical direction.

[0030] At this stage, the upper end of pipe 1 in piping unit 100B and the lower end of pipe 1 in piping unit 100A are not fully connected. For example, the lower end of pipe 1 in piping unit 100A is partially inserted into the push-fit provided at the upper end of pipe 1 in piping unit 100B.

[0031] (Frame connection process) The upper part of the frame 2 of piping unit 100B and the lower part of the frame 2 of piping unit 100A are connected.

[0032] Figure 8 shows the frame connection process for the vertical piping installation method. In Figure 8, the illustration of pipe 1 is omitted. As shown in Figure 8, the connecting vertical member 24 of the piping unit 100 has a roughly L-shape in cross-section. The vertical connecting member 42 of the piping unit 100B is fixed to the upper part of the connecting vertical member 24 with bolts 42a and nuts 42b. In the illustrated example, the vertical connecting member 42 is a square steel pipe.

[0033] By forming vertically elongated bolt holes in the connecting vertical members 24 of the piping unit 100A, the vertical position of the piping unit 100B and the piping unit 100A can be adjusted.

[0034] With the horizontal positions of piping unit 100A and piping unit 100B determined, the upper frame 21 of piping unit 100B and the lower frame 22 of piping unit 100A are connected with long bolts 44a and nuts 44b. In the illustrated example, the short-side upper frame 21 (referred to as upper frame 21A) and the short-side lower frame 22 (referred to as lower frame 22A) are connected with long bolts 44a and nuts 44b.

[0035] With the vertical positions of piping unit 100A and piping unit 100B determined, The connecting vertical member 24 of the piping unit 100A is fixed to the upper part of the vertical connecting member 42 with bolts 43a and nuts 43b.

[0036] (Vertical piping connection process) Connect the lower end of pipe 1 of piping unit 100A to the upper end of pipe 1 of piping unit 100B. Confirm that the lower end of pipe 1 of piping unit 100A is inserted into the push-fit fitting to the predetermined position.

[0037] In this vertical piping construction method, the piping unit 100A, which contains multiple pipes 1, is lifted and placed on top of the piping unit 100B installed below it, connecting the upper and lower frames 2. The lower part of the pipes 1 of the upper piping unit 100A is connected to the upper part of the pipes 1 of the lower piping unit 100B. Since multiple pipes 1 can be lifted and installed at once, rather than lifting each pipe 1 individually, multiple pipes 1 can be installed and connected efficiently.

[0038] Furthermore, the suspended piping unit 100A is placed above the lower piping unit 100B to adjust the orientation of the frame 2 of the upper and lower piping units 100B and 100A. By setting the orientation of the frame 2 to a predetermined orientation, the orientation of the piping 1 will naturally be set to a predetermined orientation, making it easy to adjust the orientation of the piping 1.

[0039] Furthermore, the frame 2 is formed in a four-sided frame shape in plan view, with multiple frame members 21, 22, and 23 spaced apart vertically and connected by vertical members 24. Therefore, since the inside and outside of the frame 2 are in communication, workers can reach their hands from the outside to the inside of the frame 2 to perform tasks such as connecting the pipes 1, thus improving work efficiency.

[0040] It should be noted that the shapes and combinations of the constituent members shown in the above-described embodiments are merely examples, and can be modified in various ways based on design requirements, etc., without departing from the spirit of the present invention.

[0041] For example, in the embodiment shown above, the frame 2 is formed from an elongated member, but it is not limited to this. The frame 2 may be formed from a panel-shaped member and be shaped like a cylinder with an opening in the vertical direction.

[0042] In addition, the shorter piping unit 100B may also be lifted by the winch mechanism 31 and installed above the piping unit 100A, similar to the piping unit 100A.

[0043] In the embodiment described above, the frame 2 of the piping unit 100 is adjusted in the alignment process so that it faces a predetermined direction, but the embodiment is not limited to this. The orientation of the piping 1 itself may also be adjusted so that it faces a predetermined direction, such as the vertical direction.

[0044] In the embodiment shown above, the upper and lower frame bodies 2 are fixed using vertical connecting members 42 and long bolts 44a, but are not limited to this. Parts of the upper and lower frame bodies 2 may be clamped and fixed with clips or the like. Alternatively, a locking portion may be formed on one frame body 2 and a locking portion may be formed on the other frame body 2, and the locking portion may be locked to the locking portion.

[0045] The Sustainable Development Goals (SDGs) are 17 international goals adopted at the UN Summit in September 2015. The vertical piping construction method according to this embodiment can contribute to achieving some of the 17 SDGs, such as Goal 9, "Build resilient infrastructure, promote inclusive and sustainable industrialization and foster innovation."
