Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a method of constructing a building structure at a narrow construction site such as in an urban area.

(Prior art and its disadvantages) In urban areas, buildings such as houses are often constructed on narrow sites bordering each other, and the demand for replacement of these buildings as they age has increased in recent years. are doing.

By the way, when rebuilding these buildings, it is always the desire of the construction owner to use the expensive site as effectively as possible by constructing a two- or three-story building to fill the narrow site. This is the place to do it. However, when such construction was carried out, the building had the following drawbacks. In order to construct a building to fill the entire site, it must be constructed so that its side walls are in contact with the side walls of adjacent buildings on the left and right. There was a drawback in that finishing work such as mortar coating could not be applied to the wall surfaces in contact with the side walls of the building.

(Object of the invention) This invention was made to eliminate the above-mentioned drawbacks, and it is possible to construct a building to fill the entire site, and,
To provide a method for constructing an architectural structure, which allows finishing work to be carried out even on the wall surface of the side wall of the building in contact with the side wall of the building adjacent to the left and right.

(Example) Examples of the present invention will be described below with reference to the drawings. In this specification, the term "front" refers to the bottom of Figure 2, and the term "back" refers to the top of the same figure.

In the construction of this example, there are other architectural structures such as houses on both sides.
, Y is constructed adjacent to the border, and for some reason, it is not possible to build scaffolding or allow workers to enter the sites on both sides. It will be held in That is, first, there are foundations 3 on which the left and right side walls 2 of the building structure I are placed on the left and right sides of the site G, as will be described later, and between these foundations 3,
Underground beams 4 and floor surfaces 5 extending at predetermined intervals from front to back are constructed of reinforced concrete, and upwardly open recesses 6 are formed at predetermined intervals from front to back on the above-ground part of the foundation 3.

It is sufficient that at least two of these recesses 6 are provided before and after each of the foundations 3.

Next, the guide rail 7 is attached to the floor surface 5 with the right end located in the right recess 6 and the left end located in the left recess 6. As shown in FIG. 3, the guide rail 7 has a mouth-shaped cross section, and includes a pair of opposing vertical walls 7A and a horizontal edge 7B extending inward from the upper ends of these opposing vertical walls J17A. These installations are performed by attaching the L-shaped angle 9 to the port 8 that has been attached to the floor surface 5 in advance and fixing the guide rail 7. After that, the foundation 3 is attached.
The temporary structure 11 is assembled on the floor surface 5 so that a work space 14 is opened on the left and right sides between the two, and the lower part does not obstruct the passage of a trolley 12, which will be described later. Note that this temporary structure 11 is made by assembling temporary materials such as steel frames using bolts, nuts, and the like. After such work, the cart 12 is guided by the guide rail 7 in the following manner. That is, the truck 12 has a truck main body 21 and a vertical jack 13 provided with a hydraulic cylinder 17 that is attached to one end of the truck main body 21 in an upwardly protruding manner. The truck body 21 is inserted and guided from one end where the vertical jack 13 is attached, so that the upper ends of the vertical jack 13 are lined up on the outside along the left and right sides of the temporary structure 11. Note that even if the carts 12 try to fall due to a load acting on the vertical jacks 13, one cart 12 will not fall because it hits the horizontal edge 7B. After arranging the carts 12 in this way, The left and right side walls 2,
The frame material 22 of the side wall 2 is placed on the upper end of the vertical jack 13, and the frame member 23 is constructed with the frame material 22 as the lower end. It is assembled in a state where it is temporarily connected to the temporary structure 11, and a wall panel 24 is attached to this frame 23. At this time, since there is a work space 14 between the other building structures X and Y and the left and right side walls 2 under construction, finishing such as applying mortar and attaching decorative panels to the outside of the left and right side walls 2 is necessary. Construction will take place.

After finishing work is carried out in this manner, the left and right carts 12 are horizontally moved simultaneously. Note that this movement is performed by an operator pushing the left and right carts 12 at the same time, but it is of course possible to perform this movement automatically. Also.

At this time, horizontal jacks 15 are attached to the upper and middle parts of the temporary structure 11, and these horizontal jacks 15 are extended in accordance with the movement of the trolley 12 to push the left and right side walls 2 outward, and the temporary structure A connecting rod 18 whose length can be changed by a screw mechanism or the like is pivotally attached to the upper part of the connecting rod 11, and its free ends are connected to the left and right side walls 2 respectively, and by rotating these screw cylinders 25, the connecting rod 18 is expanded in accordance with the movement of the trolley 12. Then, the cart 12 is horizontally moved to the recess 6 to position the side wall 2 above the foundation 3, and then the left and right vertical jacks 13 are simultaneously lowered as follows.
The hydraulic cylinders 17 of No. 3 are connected to a hydraulic prime mover (not shown), and the vertical jacks 13 are simultaneously moved downward by the hydraulic prime movers. Due to this.

The side walls 2 are each placed 121 on the foundation 3. And the side v
After connecting the lower end of 2 and the foundation 3 with bolts, nuts, etc., the mold 12 and guide rail 7 are removed, the recess 6 is reinforced with reinforcing bars, and then closed with concrete, and a beam 16 is hung on the upper end of the side wall 2. After passing, the connecting rod 18 is removed and the upper part of the temporary structure 11 is dismantled. At the same time, the beam material 16 is also passed to the middle part of the left and right side walls 2, and then the F part of the temporary 4R structure 11 is dismantled. , temporary structure 11
After complete dismantling, construction of building structure 1 will proceed using the same construction method as before.Although the building structure l constructed in this example is a steel structure, it may also be a wooden structure. Needless to say.

(Effects of the Invention) According to the above statement 1, the left and right side walls 2 of the building structure 1 are constructed within the work space 14 opened between the temporary structure 11 and the foundation 3; Finishing work can be performed on the entire wall surface of these left and right side walls 2. Also,
The left and right side walls 2 are moved to the recess 6 using a trolley 12 and placed on the bases ia3 on both sides of the site G, so that the building can be constructed to fill the entire site.
