Description

[Detailed description of the invention] The present invention relates to a method for suspending and installing a building unit.

Multiple building units factory-produced to a certain standard,
A building is constructed by installing it on a foundation formed in a predetermined shape.
When mainly constructing a house, it is preferable to use a method in which the building unit is directly hoisted onto the foundation from the bed of a truck using a crane. In addition, when constructing a building using the method described above, in order to improve labor saving on site work,
It is required to use a building unit with a high degree of completion as much as possible, and in order to construct a building with high durability and weight, a heavy building unit is desired. However, when using a building unit that is highly complete and heavy, it is easier to keep it in place without damaging it than when using a unit that is less complete or relatively lightweight. It is not easy to install a building unit, and it requires a lot of effort, especially when installing a second or subsequent building unit adjacent to an already installed building unit.

The present invention makes 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 in which a plurality of building units are suspended and installed 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. When suspending the second and subsequent building units forming a section, the above building unit to be suspended faces the side of the existing building unit that has already been installed on the foundation or on the first floor building unit. The present invention provides a hanging installation method for a building unit, characterized in that the side surface of the building unit is tilted in a direction in which the upper edge thereof is separated from the side surface of the existing building unit.

Hereinafter, the method for suspending and installing a building unit according to the present invention having the above-mentioned features will be described with reference to the drawings, with reference to an embodiment in which a plurality of building units are installed on a foundation. When implementing the present invention, first, one building unit A out of a plurality of building units brought to the site is placed at a predetermined position on a foundation C that has been formed in a predetermined shape at a predetermined position. , by a crane, using a lifting jig D shown in FIG. 5 to suspend it horizontally.

The installation of this first building unit can be easily carried out because there are still no obstructions on the foundation 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. In the invention, 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 so that its upper edge 2a is inclined in the direction away from the side surface 1 of the existing unit A. It's crowded. That is, when the tips 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 in a predetermined position. 4 in advance so that it is tilted at an angle of
By using the hanging jig D in which the length of the book chain 11 is 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 first placed on the foundation C.
Install it by hanging it so that it is in contact with the top. The angle of inclination at this time is not necessarily determined depending on the form, size, etc. of the building unit B, but usually the lower end edge 2b of one side surface 2 of the building unit B is approximately lower than the lower end edge 3b of the side surface 3 on the opposite side. Located 5cm above! It is preferable to set it to about a certain degree. In addition, when attempting to suspend the third or subsequent building unit B, if it is installed so that its two adjacent sides face the sides of two existing units that have already been installed, damage may occur. Although it is desirable to install the device with the four sides that are expected to be inclined, it is usually installed with the side surface that has a larger contact surface inclined.

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 Figure 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 apart from each other. Although they can be installed in parallel using the method of the present invention, it is preferable to suspend and install them one by one in order to improve the precision of the building. The general hanging installation method of the present invention has been described above, but the method of the present invention has steel columns 4 in four corners and a steel column at the bottom, as shown in FIGS. 3 and 4. It is a right-angled hexahedral-shaped building unit having a floor body 5 including a frame, and is effective for installing a highly complete building unit structure with appropriate external walls etc. on the side faces located on the outside of the building. It is particularly preferable to use a method in which the sheath pipe is buried in advance, anchor bolts are connected and placed in the building unit in advance, grout is injected into the sheath pipe, and then the anchor bolts are inserted into the sheath pipe and fixed. .

Incidentally, the grout material can also be injected into the sheath pipe using a hose or the like after inserting the anchor bolt. Therefore, the case where the above-mentioned highly complete unit is used in combination with the above-mentioned particularly preferable method will be explained with reference to FIG. 3. Fig. 3 shows a side surface 1 of a building unit (existing unit) A that has already been installed, and a side surface 2 facing that side 1.
This figure shows the vicinity of the lower end of each unit A, B, together with the foundation C, when another building unit B is installed by suspending it by the method of the present invention, and 4 and 4 are the existing unit A.
(7) W! 4 column and unit B to be installed
(7) It is a steel column, and anchor bolts 6, 6 are fixed in advance to the lower ends of the columns 4, 4 before installing units A, B, and the sheath pipe 7, 7 is buried in advance.

The existing unit A is installed and fixed on the foundation C by injecting the grout material 8 into the sheath pipe 7 and inserting the anchor bolt 6 therein. According to the method of the present invention, the building unit B is gradually suspended in an inclined state as shown in FIG. Column body 5
If the building unit B is suspended with the tip of the anchor bolt 6 fixed to the lower end facing the grout material 8,
While making fine adjustments so that the hanging position of building unit B with respect to the existing unit A is at the predetermined position,
can be hung and installed in correspondence with the existing unit A. Furthermore, by fixing the clearance piece 9 that regulates the distance between the columns 4 to the surface of the column 9 of the building unit B on the side of the existing unit A, even more accurate and easy hanging installation is possible. Become. The hanging installation method of the present invention described above is the fourth
When applied to installing five units as shown in the figure, in Fig. 4, when unit A is first installed as the reference unit, and then the other unit B is installed, Good, by doing so you will get the full effect.

Further, to briefly explain the preferable hanging jig D shown in FIG. , consists of four chains 11 each having a hanging hook 1'' at the other end, and a distribution frame 12 in which a part of each of the chains 11 is connected via a distribution frame suspension chain 12''. When in use, each of the hanging hooks 1' is locked to the upper end of the four pillars of the building unit, and the hanging part 10 is hoisted up using a crane. By adjusting the height, the building unit can be lifted at a predetermined angle, and the hanging hooks 11'' of each chain 11 can be easily distributed by the distribution frame 12 when the hanging part 10 is lifted. It will lock into place on the unit. Furthermore, a two-story house can be constructed by placing and combining second-story units in the same manner on top of each unit installed as described above.

As described above, the hanging installation method of the present invention involves suspending and installing a plurality of building units on a foundation formed into a predetermined shape or on a first floor building unit in which a predetermined number of building units are joined together. At that time, since the second and subsequent building units are hung and installed at an angle, the building units are not damaged and accurate positioning is easy, especially in the embodiment shown in Fig. 3. It is more effective if it is implemented.

Therefore, the present invention is particularly suitable for the construction of houses with high-quality and heavy building units. We provide manufactured housing.
