This invention relates to an exterior wall in which a PC board (precast concrete board) is attached to the outer surface of a frame wall. Conventional PC board exterior walls, which are made by attaching PC boards to the structural wall, have limited deformation performance during earthquakes, etc., and there is a risk that the external wall, which is made of continuous PC boards vertically and horizontally, will collapse in a series. There was a problem that the gap with the board was narrow and installation work was not easy. In response to these problems, according to Publication No. 52-20270,
A PC exterior wall board mounting device has been proposed that has excellent deformability and allows easy installation of the PC board. However, because this mounting device is deformable, the number of support points is limited, and a large force is applied to each support point, so for example, the mounting bracket for a PC board may become stuck to reinforcing bars etc. buried within the PC board. Therefore, the support strength had to be improved. Therefore, the PC board becomes thick, which increases the cost, and the installation requires a large lifting machine and mounting hardware that can withstand high loads, which increases the construction cost. This invention was made by paying attention to the above-mentioned problem, and its purpose is to provide a PC that has excellent deformability, has a lightweight PC board, has high installation strength, and has good installation workability.
We are proposing a board exterior wall. The present invention will be explained below with reference to illustrated embodiments. FIG. 1 shows a PC board 1 used for the outer wall of this PC board.The upper and lower ends are thick, and sleeves 2, 2 are vertically oriented and are opened and buried in the upper and lower end faces, respectively. In addition, sleeves 2, 2 are buried
The upper and lower ends of the PC board 1 are made of mortar 3 mixed with carbon fiber. Note that tiles 4 are pasted on the surface of this PC board to give it a finished surface, and the bottoms of the sleeves 2 are closed with plugs 5. In Figure 2, this PC board 1 is attached to a frame wall 6 to construct a PC board outer wall.The frame wall 6 has supporting hardware 7 horizontally arranged vertically at intervals approximately equal to the height of the PC board 1. It is installed protrudingly. The support hardware 7 is made of an L-shaped steel plate as shown in FIG.
0, and a pin insertion hole 11 is formed in the horizontal piece 7b at the tip. The bolts 9 are provided to protrude from an anchor plate 12 embedded in the surface of the frame wall 6. As shown in FIG. 4, the anchor plate 12 is made of a metal fitting with a hat-shaped cross section, and is buried with its top surface 12a exposed on the surface of the frame wall 6, and the intersection of the ends of the upper and lower side surfaces 12b and the flange 12c. It is fixed by being fixed or locked to reinforcing bars 13 arranged within the frame wall 6. And on the top surface 12a there is a vertically long loose hole 1.
4 is provided, and a side surface 1 is provided inside the top surface 12a.
A partition plate 15 is installed between 2b and 12b. The bolt 9 is inserted into the loose hole 14 of the anchor plate 12 so as to be slidable up and down, and the head 9' at the rear end is locked to the inner surface of the top surface 12a. The supporting hardware 7 has its rising piece 7a and the anchor plate 12.
A bolt 9 is inserted into the loose hole 8 while adjusting the protrusion length between the top surfaces of the bolt 1 through a spacing adjustment plate 16, and is fastened with a nut 10 through a washer plate 17 and a washer 18. A heat insulating material 19 is laid on the surface of the frame wall 6, and the PC boards 1 are laid vertically and horizontally while maintaining a ventilation space from the surface, and the lower ends are placed on the supporting hardware 7 via washers 20. place And support hardware 7
The upper and lower parts of the pin 21, which is passed through the pin insertion hole 11 and projects upward and downward from the horizontal piece 7b, are respectively inserted into the sleeves 2, 2 of the PC boards 1, 1 which are vertically opposed to each other through the sleeves. It is solidified by a hardening material 22 such as mortar filled in the inside, and a cylindrical elastic material 23 made of soft synthetic resin or the like is interposed in the lower part. An elastic back-up material 24 is fitted into the gap between the upper and lower PC boards 1, 1, and a sealing material 25 is applied.
It is filled with air and is sealed airtight. This PC board outer wall has the above-mentioned configuration, and during construction, the position of the support hardware 7 is adjusted and fixed, and the pins 21 are inserted into the pin insertion holes 11 of the support hardware 7 to connect the upper end of the lower PC board 1. The lower part of the pin 21 is inserted into the sleeve 2, and then the upper part of the pin 21 protruding upward is inserted into the sleeve 2 at the lower end of the upper PC board 1, and the upper PC board 1 is placed on the support hardware 7. Place and build. Therefore, PC boards can be installed accurately and easily. The outer wall of the PC board with this structure is made of mortar 3 mixed with carbon fibers at the upper and lower ends of the PC board, which is embedded in the sleeve 2, and has high strength. sleeve 2
Sleeve 2 without attaching to reinforcing bars etc.
develops sufficient support strength to insert the pin 21 and attach the PC board. The installed PC board is movably supported by the pin 21 within the sleeve 2, and the upper and lower PC boards are discontinuous, so that fluctuations caused by earthquakes, etc. can be mitigated and absorbed, and are also distributed and transmitted to the individual PC boards. This prevents the PC board outer wall from collapsing. In the embodiment described above, mortar 3 mixed with carbon fiber was placed on the upper and lower ends of the PC board 1, and a high-strength mortar was used around the sleeve 2.
Mortar mixed with carbon fiber may be used for the entire base material of the PC board 1. This PC board improves the support strength of the pin locking hole in which the sleeve etc. are buried, and also improves the strength of the entire PC board, and can be made into an extremely thin board without using reinforcing bars or the like. Therefore, workability is further improved, and pin locking holes, etc.
The load on the PC board mounting area is reduced, and the mounting strength can be further improved. Furthermore, if the surface of the PC board is used as a finished surface, there is no need for surface finishing on site, which can streamline construction. The carbon fibers used in this invention can be high-strength, high-modulus, and high-modulus carbon fibers produced by firing acrylic fibers at high temperatures, or low-modulus carbon fibers produced by firing petroleum or coal pits at relatively low temperatures. Its typical physical properties are shown in the table below.

性がよい。[Table] Although low-modulus carbon fibers have lower tensile strength and elastic modulus than high-modulus ones, they have sufficient performance to be mixed into mortar to reinforce PC boards, and are cheaper than high-modulus ones. Therefore, it is suitable for use in this invention. The mixing amount is 10Kg per 1m3 of mortar.
The amount is about 100 kg, and if it is less than 10 kg, the reinforcing effect will be poor, and if it is more than 100 kg, the reinforcing effect will be lower than the mixing amount, which is not preferable as it will increase the cost. In addition, carbon fiber does not deteriorate and maintains its reinforcing effect for a long time, and its strength does not decrease even when it is cured in high temperature and high pressure steam (autoclave curing) when manufacturing PC boards. A highly stable carbon fiber reinforced PC board can be obtained. Therefore, the mounting accuracy of the PC board outer wall is improved, and the PC
Even if tiles are driven and pasted onto the board surface to create a finished surface, the PC board base material will not shrink or warp, so there is no risk of tiles peeling off or cracking. This invention is as described above, and this PC board outer wall has excellent deformation resistance against vibrations caused by earthquakes, etc.
The mounting strength of the PC board is high, and the installation workability of the PC board is also good.
