DETAILED DESCRIPTION OF THE INVENTION The present invention involves laying bricks vertically and horizontally in advance, and
A brick panel consisting of a sheath buried vertically through the masonry is erected on the foundation, a PC steel material anchored at the lower end to the foundation is inserted into the sheath and temporarily tightened, and then the brick panel is placed on top of the brick panel. A reinforced concrete horizontal member is cast on the horizontal member, and an upper brick panel configured in the same manner as the above panel is erected on the horizontal member, and the PC is placed in the sheath within the panel.
The upper PC steel member connected to the steel member is inserted and temporarily tightened, and then the upper reinforced concrete horizontal frame member is cast on the upper brick panel, and the above construction is repeated to install the uppermost horizontal frame member. In the material, each of the above-mentioned sections passing through the sheath of each of the brick panels as well as each horizontal member
This method of constructing a structure is characterized by anchoring prestressed steel under tension, and its purpose is to construct a structure based on prestressed brick blocks that are easy to construct and have high structural reliability. The purpose of this invention is to provide a method for constructing a structure.

The present invention will be described below with reference to the illustrated embodiments.

In (A), perforated bricks 2 each having a vertical hole 1 are stacked in advance using joint mortar so that the joints of the upper and lower layers are inconsistent and the vertical holes 1 communicate in the vertical direction. A sheath 3 is inserted and buried in the vertical through holes formed by the vertical holes 1, and a PC steel wire 4 is inserted into each vertical hole formed by the vertical holes 1, and both ends of the wire are secured with long nuts 5. It is a brick panel that is anchored.

In addition, 6 in the figure is a flat bar horizontally suspended between the bricks 2 at both the upper and lower ends of the brick panel A.

Then, the brick panel A of the first floor is built on the foundation B, and the anchor 7 buried in the foundation B is welded to the long nut 5 (see Fig. 1), and the foundation B and brick panel A are assembled. The brick panel A is held horizontally by the adjuster 8 interposed between the foundation B, and the PC steel rod p is anchored to the anchoring recess 9 provided in the foundation B via a nut 10 and a washer 11. While loosely inserting it into the well 12 of
(See figure) Temporarily tighten the PC steel bar p above the brick panel A. (See FIG. 3) Next, mortar 13 is loaded between the panel A and the foundation B, and an anchor 14 is attached to the long nut 5 at the upper end of the panel A. (See Figure 4) Next, a reinforced concrete slab C for the second floor is poured on the panel A, and the anchoring recess 15 of the slab C is placed.
While facing the upper end of the PC steel material p,
A vertical hole 16 communicating with the recess 15 is provided. (5th
(See figure) Next, an anchor 17 is anchored to the slab C, and is anchored to the long nut 5 of the brick panel A' on the upper floor, which is built on the slab C and is constructed in the same manner as the panel A. (Refer to Fig. 6) Next, the brick panel A' is horizontally adjusted by the adjuster 18 interposed between the brick panel A' and the slab C, and the lower PC steel material P is connected to the anchoring hole 15 via the coupler 19. Insert the prestressed steel material p' joined to the hole 16 and the sheath 3 of the brick panel A' (see Fig. 7), then temporarily tighten the prestressed steel material p and p' on the upper part of the panel A'. Let's do it. (See FIG. 8) Furthermore, an anchor 20 is anchored to the upper nut 5 of the brick panel A'. In the figure, 21 is a coupler attached to the end of the PC steel material p'. Also said brick panel
Mortar 22 is loaded between A' and slab C.
(See Fig. 9) Next, a reinforced concrete roof slab D is cast on the brick panel A', and (see Fig. 10) a PC steel material p'' is inserted into the vertical through hole 23 of the roof slab D. The PC steel materials p, p', p'' are connected to the steel material p' via the coupler 21, and each of the PC steel materials p, p', p'' is tension-anchored from the upper part of the roof slab D using a hydraulic jack.
(See Figure 1) After that, from the anchoring recess 9 of the reinforced concrete foundation B, the pit 12 of the foundation A, the sheath 3 of the brick panel A, the pit 16 of the slab C, the sheath 3 of the brick panel A', and the roof slab D. Pit 2
The entire process is completed by injecting and filling the grout 24 over three steps. (See Figure 12) In the present invention, as described above, a brick panel is used as a structural wall, which is constructed by masonry of bricks in advance vertically and horizontally, and a sheath embedded vertically through the masonry. is built on the foundation, the PC steel material anchored to the foundation is inserted into the sheath of the panel and temporarily tightened, reinforced concrete horizontal members are cast on the same panel, and the upper brick is placed on top of it. The panels are erected, the upper PC steel material connected to the PC steel member in the horizontal member is inserted and temporarily tightened into the sheath of the upper brick panel, and the upper reinforced concrete horizontal member is placed on top of the same brick panel. The above process was then repeated to tension-anchor the PC steel materials that penetrated the sheaths and horizontal members of each brick panel at the uppermost reinforced concrete horizontal member. When erecting brick panels, the panels are temporarily fastened to the foundation and horizontal members using the prestressing steel, so the panels can stand on their own without the use of supports, greatly reducing temporary construction work. Ru. Furthermore, regarding each of the brick panels and horizontal members,
Since prestress is introduced by the prestressing steel,
A structurally rational structure that strongly resists external forces, especially horizontal forces, is to be constructed.Furthermore, in the present invention, as described above, a brick panel made of pre-laid bricks is erected. The present invention has many advantages, such as the fact that by using it as a structural wall, the process is significantly simplified, the construction period is shortened, and the construction cost is reduced.

Although the present invention has been described above with reference to embodiments, the present invention is, of course, not limited to such embodiments, and can be modified in various ways without departing from the spirit of the present invention. .
