Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of installing building units, with particular application to certain suspended installation methods.

Multiple building units factory-produced to a certain standard,
A building is installed and installed on a foundation formed in a predetermined shape,
When primarily constructing housing, it is preferable to use a method in which the building units are hoisted directly onto the foundation using a crane from the bed of a truck. In addition, when constructing a building using the method described above, it is necessary to use a building unit with a high degree of completion as much as possible in order to improve labor savings on site work. In order to construct a building with a sense of style, a heavy building unit is desired. However, when using highly complete and heavy building units, it is easier to position the building unit in place without damaging it than when using less complete or relatively lightweight units. It is not easy to accurately install a building unit, and it requires a great deal of effort, especially when installing a second or subsequent building unit adjacent to an already installed building unit.

Therefore, the present inventor has made it possible to accurately and easily install a plurality of highly complete and heavy building units on a foundation or on a first floor building unit that is a combination of a predetermined number of building units. A method of installing a plurality of building units is to suspend and install a plurality of building units on a foundation formed into a predetermined shape or on a first floor building unit that is a combination of a predetermined number of building units. Or, when suspending the second and subsequent building units forming the second floor, the side facing the side of the existing building unit that has already been installed on the foundation or on the first floor building unit shall be suspended. The present invention has invented a hanging installation method for a building unit, which is characterized in that the side surface of the building unit is inclined in a direction in which the upper edge thereof is separated from the side surface of the existing building unit.

As mentioned above, when constructing a building by installing and combining a plurality of building units, in order to more accurately and easily position the units, it is necessary to position each unit on the side so that the units maintain a predetermined distance from each other. It is conceivable to attach a clearance piece to the side of the existing unit, but if the clearance piece is attached, it tends to get in the way of installation work, and especially when using the above-mentioned hanging installation method, the clearance piece is attached to the side of the existing unit. Doing so will make installation work extremely difficult.

The present invention has been made in view of the above points, and is a building unit in which the building unit can be installed more accurately and easily by attaching and installing a clearance piece at a specific position of the building unit. This provides an installation method.

That is, the installation method of the present invention installs a plurality of building units,
When installing on a foundation formed into a predetermined shape or on a first floor building unit that is a combination of a predetermined number of building units, the installation of the second and subsequent building units forming the first or second floor shall be as follows: A clearance piece for maintaining a predetermined distance between units, below the side of the building unit to be installed, on the side facing the side of the existing building unit that has already been installed on the foundation or on the first floor building unit. There are some that are characterized by being performed by wearing a Hereinafter, a case where the installation method of the present invention having the above characteristics is applied to a hanging installation method, which is a preferred embodiment thereof, will be explained with reference to the drawings. First, one building unit A out of the plurality of building units selected for the site is placed at a predetermined position on a foundation C that has been formed in a predetermined shape at a predetermined position.
It is hoisted down horizontally by a crane using a hoisting jig D shown in FIG.

The installation of this first building unit is still at its foundation. This is easy because there are no obstacles on C. Next, another building unit B is installed with its side 2 facing one side 1 of the above building unit (existing unit) A that has already been installed on the foundation C. As shown in FIG. 1, the side surface 2 of the building unit B facing the side surface 1 of the existing unit A is suspended with its upper edge 2a inclined in a direction away from the side surface 1 of the existing unit A. That is, when the ends of the four chains 11 of the lifting jig D are locked to the upper ends of the four corners of the building unit B and the building unit B is lifted, one side 2 of the building unit B is placed in a predetermined position. Set the four chains 1 in advance so that the angle is tilted.
By using the jig D for hanging with the length of 1 adjusted, the building unit B is tilted as described above, and the lower edge 3b of the side surface 3 opposite to the side surface 2 is brought into contact with the foundation "C" first. The inclination angle at this time is not necessarily determined depending on the form, size, etc. of the building unit B, but usually the lower edge 2b of one side 2 of the building unit B is
Preferably, the angle is approximately 5C7X above the lower edge 3b of the side surface 3 on the opposite side. In addition, when attempting to suspend the third or subsequent building unit B, if the two adjacent sides thereof face the respective sides of two existing units that have already been installed, the Install with the larger side slanted.

Furthermore, Fig. 1 is a side view of building units A and B as seen from the larger side, and Fig. 2 is a side view of building unit A.
, B, respectively, are side views seen from the smaller side,
Therefore, Fig. 1 shows a mode in which the smaller side surface is inclined and the hanging installation is attempted, and Fig. 2 shows a mode in which the larger side surface is inclined and the hanging installation is attempted. . Furthermore, as shown in Fig. 2, building unit B is installed in a position adjacent to existing unit A, but building units B and B are installed in positions completely separate from each other.
Regarding B, although it is possible to suspend and install two units in parallel, it is preferable to suspend and install one unit at a time in order to improve the accuracy of the building.

The general aspects of the hanging installation method for building units have been explained above, but the above hanging installation method
As shown in Figures 4 and 4, it is a right-angled hexahedral building unit with steel columns 4 at the four corners and a floor 5 including a steel frame at the bottom, with appropriate external walls on the sides located on the outside of the building. It is effective for installing a highly complete building unit structure with a sheath, etc., and it is also possible to bury the sheath pipe in the foundation in advance, connect anchor bolts to the building unit in advance, and place grout inside the sheath pipe. It is particularly preferable to use a method of inserting and fixing an anchor bolt into the sheath tube after injecting the sheath tube.

Incidentally, the grout material can also be injected into the sheath pipe using a hose or the like after inserting the anchor bolt. Next, the case where the above-mentioned highly complete unit is suspended and installed using the above-mentioned particularly preferred installation method (pre-grouting method) will be explained with reference to FIG. 3. Third
The figure shows each unit in the case where another building unit B is installed by hanging on one side 1 of an already installed building unit (existing unit) A with the side 2 facing the side 1 inclined. The vicinity of the lower ends of A and B are shown together with the foundation C, and 4 and 4 are the steel columns of the existing unit A and the steel columns of the unit B to be installed. Anchor bolts 6, 6 are fixed in advance to the lower ends of the units A, B before installation, and sheath pipes 7, 7 are buried in the foundation C in advance.

The existing unit A is installed and fixed on the foundation C by inserting the grout material 8 into the sheath pipe 7 and inserting the anchor bolt 6 therein. Therefore, in the above-mentioned hanging installation method, the building unit B is gradually hung in an inclined state as shown in FIG.
At that time, grout material 8 is injected into the sheath pipe 7,
If the building unit B is suspended with the tip of the anchor bolt 6 fixed to the lower end of the steel column 5 facing the grout material 8, the hanging position of the building unit B relative to the existing unit A or a predetermined position can be adjusted. Building unit B can be suspended and installed in correspondence with the existing unit A while making fine adjustments so that the building unit B is aligned with the existing unit A. As described above, the method for installing a building unit of the present invention is that when installing another building unit B adjacent to an existing unit A, as shown in FIG. Building unit B to be installed on the side
In building unit B, which has a steel column 4 below the side surface of the column, that is, at the corner, there is a wall between the units A and B, that is, between the respective columns 4 and 4, below the side surface of the column 4. A clearance piece P is attached to maintain a predetermined distance between the two units A and B by bringing this clearance piece P into contact with the column 4 of the existing unit A. Can be regulated accurately.

In particular, if the above-mentioned slanted hanging installation method is applied, the clearance piece P will not only be out of the way until the building unit B is installed in the predetermined position, but also the clearance piece P and the column 4 of the existing unit A The clearance piece P also serves as a guide when installing the building unit B at a predetermined position. If this clearance piece P is attached to the pillar body 4 of the existing unit A without following the present invention, problems such as the lower end of the building unit B being caught on the clearance piece P will occur when the building unit B is installed. Not only will the effect of installing the piece not be achieved, but also harmful effects will occur. In addition, when five building units are installed as shown in FIG. 4, in FIG. It is only necessary to apply it, and by doing so, a sufficient effect will be exhibited.

Further, to briefly explain the preferred hanging jig D used in the embodiment of the present invention shown in FIG. 5, this hanging jig D has a hanging part 10 and one end connected to the hanging part 10. four chains 11 each having a hanging hook 1'' at the other end; and a distribution frame 12 whose corners are connected to a part of each of the chains 11 via a distribution frame suspension chain 12''. When in use, each of the hanging hooks 1'' is engaged with the upper ends of the pillars at the four corners of the building unit, and the hanging part 10 is lifted up by a crane.

At that time, by adjusting the lengths of the four chains 11, the building unit can be lifted at a predetermined angle, and the hanging hooks 11'' of each chain 11 When lifted, the units are sorted by the sorting frame 12, so they can be easily locked in the predetermined positions of the units.By applying the method of the present invention, the above-mentioned units are placed on top of each unit installed as shown in FIG. By placing and joining the units on the second floor according to the method, a two-story building can be constructed.

As described above, the method for installing a building unit of the present invention is to install a building unit adjacent to an existing unit by attaching a clearance piece to a specific position of the building unit to be installed later. It enables the unit to be installed accurately and easily in a predetermined position,
In particular, when applied to the above-mentioned hanging installation method and used in combination with the above-mentioned pre-grouting method, the saw layer effect can be enhanced, and therefore, it is suitable for the construction of industrialized housing with high-quality and heavy building units. This is a huge contribution.
