Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a construction method for plumbing equipment spaces in mid-to-high-rise buildings.

In mid-to-high-rise buildings such as government offices and offices, the second and higher floors usually have the same plan. This is because it is convenient for maintenance and management to have the same plan not only for elevators, stairs, ducts, and various shafts, but also for water-related equipment spaces such as toilets, washrooms, kettle rooms, and kitchens, which are closely related to these.

By the way, in the finishing work of such mid-to-high-rise buildings, the majority of jobs such as plasterers, tile workers, waterproofers, joiners, plumbers, electricians, etc. are concentrated in just one section of plumbing equipment space, so the process is slow. It was disorganized and inefficient. Recently, products that have focused on this point and have integrated bathrooms and washrooms have become popular. We have not yet reached the point where we have reduced the equipment space and made it into a unit.

The purpose of the present invention is to solve the above-mentioned congestion of finishing work by focusing on the coplanarity of the plumbing equipment space on the standard floor of medium-to-high-rise buildings. In the construction of the frame, by omitting the slabs on each floor in the area of the plumbing equipment space, a core shaft-shaped vertical space is formed in the area of the plumbing equipment space, and a three-dimensional frame is installed at the bottom of the vertical space. A core unit that incorporates a plumbing equipment unit is brought into the building, and the first core unit, that is, the one on the top floor, is lifted up one floor at a time using a lift-up device installed at the top of the core shaft-shaped vertical space. Construction of plumbing equipment spaces in mid-to-high-rise buildings characterized by repeatedly adding core units on lower floors and lifting up all floors to their respective predetermined floors, and then fixing all core units as they are to the core shaft. It's in the law.

Hereinafter, the configuration of the present invention will be explained with reference to the drawings. In the plumbing equipment space A of a mid-to-high-rise building with a plane as shown in Fig. 1, a core shaft 1 is formed with a well-known wall without constructing a concrete slab.
Later, a three-dimensional frame 3 (hereinafter referred to as a core unit 4) having a plumbing equipment unit 2 installed therein is installed. The three-dimensional frame consists of beams 3a and columns 3b, and each three-dimensional frame is connected vertically when completed (see FIG. 3).

To install the core unit, as shown in Figure 2, first, the components of the three-dimensional frame 3 and the plumbing equipment unit 2 that were brought to the first floor were brought into the core shaft and assembled there to form the core unit 4, and then the upper beam of the first core unit was installed. is attached to the lower end of the rod 5b which is suspended from the jack 5a of the restup device 5 installed at the top of the core shaft so that it can be raised and lowered,
The lift rises slightly higher than the first floor. Next, the constituent members of the lower floor are brought in and assembled into a core unit, and the core unit of the upper floor, which was previously lifted up, is lowered slightly and integrated with it using the connecting member 6. Then, lift it up one floor again, assemble a new core unit below it, and repeat the process of adding and integrating. In this way, when the first core unit reaches the top floor, the plumbing equipment spaces of all other standard floors are filled with the core unit, so it is pushed into the core shaft 1 and fixed by welding to the anchor plate 7, etc., and then the lift-up device is removed. Finish by connecting piping (not shown) between each core unit.

Since the present invention is configured as described above, it is easy to unitize the plumbing equipment space, thereby eliminating congestion during finishing work, and as a result, it has the advantage of increasing the efficiency of construction.
