Description

  The present invention relates to a seismic wall and a method for constructing it, which can rationally ensure lighting and ventilation while securing the strength of a block and can be constructed while living.

  For example, Patent Document 1 is known as an earthquake-resistant wall constructed by arranging a precast concrete block in an opening section partitioned by a column and a beam. In Patent Document 1, a large number of seismic blocks that form a quadrilateral as a whole with outer grooves formed on the outer periphery and a mountain block that forms a triangle by halving them are surrounded by the pillars and beams of the building. The two diagonal lines of the seismic blocks are individually oriented in the vertical direction and the left-right direction, and the grooves of the two seismic blocks are made to face each other. While constructing a space for accommodating reinforcing bars, the large number of seismic blocks and mountain blocks are built, and a solidified material such as concrete mortar is filled in the space formed by the concave grooves, and this consolidation is performed. The adjacent earthquake-resistant blocks are connected to each other via a material and the exposed reinforcing bar to enhance the earthquake resistance of the structural surface.

The earthquake-resistant block includes a V-shape and may be a triangle or a polygon. The seismic block is formed with a window-like hole penetrating the front and back at the central portion, leaving a portion of the outer periphery where the concave groove is formed in a frame shape. An outer end frame is provided inside the left and right columns and the upper and lower beams that form a frame shape as a whole in which the seismic blocks are disposed. This outer end frame is connected to each pillar and each beam, anchor bars that are planted in two rows along the longitudinal direction, and main bars that are installed to extend in the longitudinal direction. It consists of strips to be cast and cast-in-place concrete that is placed to cover these reinforcing bars. Concrete is placed after at least each block in the vicinity of the pillars and beams is built. Furthermore, with respect to the window-shaped hole, not only the construction surface surrounded by the pillars and the beams receives an open impression, but also allows airflow and light to pass through.

  By the way, in the conventional seismic wall, in order to secure lighting and ventilation, a window-like hole is formed in the block itself in contrast to the opening part partitioned by the pillar and the beam being blocked by the seismic wall. I was doing. When the window-like hole is formed in the block as described above, there is a problem that the strength of the block itself may be lowered. In addition, as a structure that joins the block assembled in the opening part to the pillar and beam, after placing various reinforcing bars such as anchor bars, the cast-in-place concrete is placed to construct the outer end frame, Anchor construction to anchor anchor bars to existing pillars and beams is necessary, especially when installing seismic walls on existing pillars and beam frames. There was a problem that it was not possible.

DESCRIPTION OF EMBODIMENTS Hereinafter, preferred embodiments of a shear wall and a construction method thereof according to the present invention will be described in detail with reference to the accompanying drawings. The earthquake-resistant wall 1 according to the first embodiment is basically an earthquake-resistant wall 1 constructed in an opening 4 divided by a column 2 and a beam 3 as shown in FIGS. The oblique sides w are arranged in the arrangement in which the oblique sides w face each other in the vertical and horizontal directions and the opposite oblique sides w are joined together to form an opening S surrounded by the vertical side y and the lateral side x, and The precast concrete octagonal block 5 to which the vertical side y and the horizontal side x are joined to the column 2 and the beam 3, and the gap between the hypotenuse w of the octagonal block 5 and the column 2 and the beam 3. It is provided with sealing blocks 6 and 7 made of precast concrete which are arranged to be sealed and joined thereto.

  A rectangular opening portion 4 is formed in the column / beam frame composed of the column 2 and the beam 3 by being partitioned by a pair of left and right columns 2 and a pair of upper and lower beams 3. A seismic wall 1 is constructed in the opening 4. In the present embodiment, the earthquake resistant wall 1 includes an octagonal block 5 stacked in the opening portion 4, and sealing blocks 6 that seal gaps generated between the octagonal block 5 and the columns 2 and the beams 3. 7. As shown in FIG. 2, the octagonal block 5 has a constant thickness, and as shown in FIG. 2, the opposing vertical sides y are parallel to each other and have the same length, and the opposing lateral sides x are also parallel and identical to each other. The four diagonal sides w connecting the vertical side y and the horizontal side x are all the same length size and are opposite to each other. The lengths of the vertical side y and the horizontal side x may be the same or different.

  As the sealing blocks 6 and 7, a block 7 having a constant thickness matching the thickness of the octagonal block 5 and having a triangular outer shape and an isosceles trapezoidal block 6 are used. As shown in FIG. 3, the isosceles trapezoidal block 6 has a length dimension in which the short side txy of the short length matches the length of the vertical side y and the horizontal side x of the octagonal block 5, and the hypotenuse tw is The length dimension that matches the length of the hypotenuse w of the octagonal block, and the long base tb that matches the length dimension between the vertical sides y and the horizontal sides x of the octagonal block 5 Formed with. Further, the triangular block 7 is formed of a right-angled triangle having a length dimension in which the base rb opposite to the vertical apex angle matches the length of the hypotenuse w of the octagonal block 5. In the illustrated example, the outermost dimension of the largest octagonal block 5 among these blocks 5 to 7 is, for example, about 500 mm. Of course, other external dimensions may be used. These blocks 5 to 7 are all made of precast concrete.

  These blocks 5 to 7 are preferably formed of high-strength concrete. For example, the blocks 5 to 7 are formed of fiber-reinforced cement, fiber-reinforced mortar, or fiber-reinforced concrete mixed with a reinforcing fiber material such as steel fiber or glass fiber. This makes it possible to form blocks 5 to 7 that are lightweight and have high strength without embedding reinforcing bars.

  The octagonal blocks 5 are arranged vertically and horizontally in the vertical direction and the horizontal direction of the opening portion 4. At this time, the adjacent octagonal blocks 5 are always arranged such that the hypotenuses w face each other. That is, as shown in FIG. 1, when any one octagonal block 5 is taken as an example, each one of the four octagonal blocks 5 faces each of the four hypotenuses w. Arranged. As a result, two octagonal blocks 5 are arranged on the right side and the left side of the octagonal block 5 at intervals of the length dimension of the vertical side y. This arrangement also has a relationship in which two octagonal blocks 5 are positioned on the upper side and the lower side of the octagonal block 5 with an interval of the length of the horizontal side x. The octagonal blocks 5 that are spaced apart from each other have a positional relationship in which the horizontal sides x and the vertical sides y face each other.

  As a result, an opening S surrounded by the vertical side y and the horizontal side x of these octagonal blocks 5 is formed around any one octagonal block 5 by the other four octagonal blocks 5. When the surrounding octagonal block 5 is viewed from the opening S, the opening S is surrounded by the vertical side y and the horizontal side x of the four octagonal blocks 5 arranged around the opening S, and is formed in a rectangular shape.

  Of the octagonal block 5, the octagonal block 5 that is in contact with the column 2 and the beam 3 is disposed such that the vertical side y and the horizontal side x face the column surface 2a and the beam surface 3a. . Therefore, since the hypotenuse w of the octagonal block 5 cannot contact the column surface 2a or the beam surface 3a, a gap is generated between the hypotenuse w of the octagon block 5 and the column surface 2a or the beam surface 3a. Sealing blocks 6 and 7 are disposed in these gaps. In a triangular gap between the corner of the opening 4 and the hypotenuse w of the octagonal block 5, a matching triangular block 7 is disposed to seal the gap. On the other hand, an isosceles trapezoidal block 6 is arranged in the gap between the hypotenuse w of the octagonal block 5 that makes a pair in the vertical direction or the horizontal direction and the column surface 2a or the beam surface 3a to seal it. Established. The isosceles trapezoidal blocks 6 are arranged such that their hypotenuse tw faces the hypotenuse w of the octagonal block 5 and the base tb faces the column surface 2a or the beam surface 3a. The opening S is formed by being surrounded by a combination of 5 vertical sides y and horizontal sides x.

  Adjacent octagonal blocks 5 are joined together with their hypotenuses w adhered to each other with an adhesive. In this way, the octagonal block 5 has a hypotenuse w serving as a joint portion with another octagonal block 5 and a stress transmission portion, so that the joint strength by the adhesive is ensured and the block 5 itself In order to ensure high strength and structural strength as the earthquake-resistant wall 1, it is preferable that the length of the hypotenuse w is longer than the length of the vertical side y or the horizontal side x. However, if the hypotenuse w is formed longer, the size of the opening S becomes smaller. Therefore, it is desirable to set the length of the hypotenuse w in consideration of the balance with the size of the opening S.

  The octagonal block 5 and the isosceles trapezoidal block 6 are also bonded by bonding their oblique sides w and tw to each other with an adhesive. The octagonal block 5 and the triangular block 7 are bonded to each other with the hypotenuse w and the base rb adhered to each other with an adhesive. The octagonal block 5 is joined to the column surface 2a and the beam surface 3a by adhering the vertical sides y and the horizontal sides x with an adhesive. The isosceles trapezoidal block 6 is joined to the column surface 2a and the beam surface 3a by adhering their bases tb with an adhesive. Further, the triangular block 7 is joined to the column surface 2a and the beam surface 3a by adhering their hypotenuses rw with an adhesive.

The construction method of the earthquake-resistant wall 1 according to the first embodiment includes a step of appropriately disposing the sealing blocks 6 and 7 along the inner circumference of the opening portion 4, and an octagonal shape vertically and horizontally in the opening portion 4. The step of disposing the blocks 5 and the hypotenuses w of the octagonal blocks 5 facing each other, the octagonal blocks 5 and the sealing blocks 6 and 7, the blocks 5 to 7, the column surface 2 a and the beam surface 3a with a bonding material. In short, the procedure of arranging the blocks 5 to 7 so as to reach the opening portion 4 and the procedure of joining the blocks 5 to 7 and the blocks 5 to 7 to the pillar 2 and the beam 3 with an adhesive are appropriately timed. Then, the wall 1 may be constructed in the opening portion 4 by the blocks 5 to 7. In particular, since the sealing blocks 6 and 7 are formed according to the dimensions of the vertical side y, the horizontal side x, and the oblique side w of the octagonal block 5, for example, a triangular block is formed at the corner of the lower portion of the opening 4 7 is arranged, and the isosceles trapezoidal block 6 is arranged below the opening portion 4 with an interval of the length of the lateral side x of the octagonal block 5. As a ruler, the octagonal blocks 5 can be sequentially and easily arranged in the vertical and horizontal directions.

In the earthquake-resistant wall 1 and its construction method according to the first embodiment described above, the hypotenuses w are formed in an octagonal shape and arranged in the vertical and horizontal directions in the opening portion 4 in an array in which the hypotenuses w face each other and face each other. There are joined together, since mainly octagonal block 5 forming an opening S that surrounds at the vertical side y and the horizontal side x, unlike to form such as a window-like hole as in the prior art to block itself, By combining the octagonal blocks 5 formed as a single body, the opening S that ensures lighting and ventilation can be rationally formed in the earthquake resistant wall 1 while ensuring the strength of the octagonal blocks 5 themselves is high. And the design of the earthquake-resistant wall 1 can also be improved by the arrangement of the openings S.

Further, the strength of the octagonal block 5 itself can be secured high, and the rigid earthquake resistant wall 1 is constructed by stacking the octagonal block 5 and the sealing blocks 6, 7. In addition, it is not necessary to arrange reinforcing bars or the like which are reinforced while connecting the blocks 5 to 7 themselves, and accordingly, the hypotenuses w of the octagonal block 5, the octagonal block 5 and the sealing blocks 6, 7. The earthquake-resistant wall 1 can be constructed by a joining operation in which the octagonal block 5 and the sealing blocks 6 and 7 are bonded to the columns 2 and the beams 3 with an adhesive. Thus, since the earthquake-resistant wall 1 is constructed | assembled by joining by an adhesive material, there is no noise, a vibration, and dust generation | occurrence | production, and the earthquake-resistant wall 1 can be constructed while staying.

  In addition, by forming the length of the hypotenuse w of the octagonal block 5 longer than the length of the vertical side y and the horizontal side x, the strength of the block 5 itself and the high bonding between the blocks 5 are ensured while ensuring lighting and ventilation. The strength and also the high strength as the earthquake-resistant wall 1 can be ensured. Further, as the sealing block, the oblique side tw having a length that matches the length of the oblique side w of the octagonal block 5 and the top side having a length that matches the length of the vertical side y and the horizontal side x of the octagonal block 5. Since the isosceles trapezoidal block 6 having txy is used, the octagonal block 5 can be easily and smoothly stacked using the isosceles trapezoidal block 6 arranged around the opening portion 4 as a ruler.

  In addition, blocks 5-7 are made of high-toughness and high-strength fiber-reinforced cement, fiber-reinforced mortar, and fiber-reinforced concrete, so they are lighter than when blocks of the same strength are made of ordinary concrete. In addition, the strength of the blocks 5 to 7 themselves and the earthquake-resistant wall 1 can be further ensured, and the unreinforced earthquake-resistant wall 1 can be obtained, thereby improving the workability. Furthermore, in the first embodiment, since the outer dimension of the largest octagonal block 5 is about 500 mm, the construction is performed in a narrow space, such as in the case of adding the earthquake-resistant wall 1 in an existing building. However, the seismic wall 1 can be constructed appropriately and smoothly.

  Further, with respect to the octagonal block 5, it is preferable that the outer contour is a regular octagon and the hypotenuse w is set to 45 ° from the viewpoint of advantageously ensuring the force transmission action. Moreover, the form of the opening S can be changed in design by making the lengths of the vertical side y and the horizontal side x different. Moreover, in 1st Embodiment, although the case where the triangular block 7 was arrange | positioned in the corner part of the opening part 4 was illustrated and demonstrated, the triangular block 7 should just be provided as needed. Providing the triangular block 7 is advantageous in terms of structural strength, but if omitted, that portion can also be used for daylighting and ventilation.

  FIG. 4 shows a second embodiment of the earthquake resistant wall 1 according to the present invention. The second embodiment is the same as the first embodiment except that the hole 8 is formed at the center of the octagonal block 5. A force is transmitted to each octagonal block 5 of the earthquake-resistant wall 1 constructed by joining the oblique sides w of the octagonal block 5 in a direction perpendicular to the oblique side w. When the transmission form of this force is examined, when the thickness of the octagonal block 5 is constant, the central portion of the octagonal block 5 has a sufficient margin for structural strength. Therefore, in the second embodiment, the hole 8 is formed in the central portion of the octagonal block 5. As a result, the daylighting / ventilating performance can be further improved, and the cost can be reduced by reducing the weight of the octagonal block 5 and reducing the amount of material. Even in such a second embodiment, it can be constructed in the same manner as in the first embodiment, and of course has the same functions and effects.

  5 to 7 show a third embodiment of the earthquake resistant wall 1 according to the present invention. The third embodiment is the same as the first embodiment except that the central portion 5a of the octagonal block 5 is formed thin and the outer peripheral portion 5b surrounding the central portion 5a is formed thick. It is the same. Although the hole 8 is formed in the octagonal block 5 in the second embodiment, the thickness of the block 5 is considerably thick.

  In the third embodiment, the thickness of the octagonal block 5 can be made relatively thin while ensuring the necessary strength. By forming the central portion 5a as a web and the outer peripheral portion 5b as a flange, it is possible to secure a high structural strength while reducing the volume of the octagonal block 5 as a whole. Thereby, while the lighting and ventilation performance is equivalent to that of the first embodiment, the cost reduction due to the weight reduction of the octagonal block 5 and the reduction of the material amount can be further improved as compared with the second embodiment. . Even in the third embodiment, the construction can be performed in the same manner as in the first embodiment, and the same operations and effects can be obtained.

  FIG. 8 shows a fourth embodiment of the earthquake resistant wall 1 according to the present invention. In the first to third embodiments, the case where the octagonal block 5 can be directly joined to the column surface 2a or the beam surface 3a of the opening portion 4 has been described as an example. Depending on the dimensional relationship, the octagonal block 5 may not be directly applied to the column surface 2a or the beam surface 3a. In 4th Embodiment, the earthquake-resistant wall 1 using the sealing blocks 9-12 which can adjust the accommodation allowance of the octagonal block 5 is shown, and these octagonal blocks 5 are these sealing. It joins to the column surface 2a and the beam surface 3a via the blocks 9-12. In the illustrated example, the upper left corner of the opening portion 4 is accommodated from the bottom corner portion of the triangular block 7, and the vertical side y and the horizontal side of the octagonal block 5 have a thickness corresponding to the amount of accommodation. A first sealing block 9 having a length of about ½ of x and having leg portions 9a projecting is used. Depending on the arrangement of the first sealing block 9, the bottom surface of the isosceles trapezoidal block 6 is arranged on the column surface 2a and the beam surface 3a in the downward direction and the right direction of the first sealing block 9, The second sealing block 10 is formed with a pedestal portion 10a projecting from the opposite sides of the octagonal block with a length of about 1/2 of the longitudinal side y and the lateral side x. It is shown. On the other hand, the third sealing block 11 and the fourth sealing block 12 are combined to accommodate the upper right corner of the opening portion 4, and an opening S is also formed between these and the octagonal block 5. The third sealing block 11 along the upper edge of the upper right corner has substantially the same shape as the second sealing block 10, and only the protruding dimension of the right protruding portion that is in contact with the column surface 2 a is the eight directly below. It is set to the size of the allowance between the vertical side x of the square block 5 and the column surface 2a. On the other hand, the fourth sealing block 12 is formed in an outer shape that fits between the column surface 2 a and the third sealing block 11 based on the second sealing block 10. Even if the octagonal block 5 cannot be directly applied to the column surface 2a or the beam surface 3a by using the sealing blocks 9 to 12 having such a margin, these sealing blocks 9 to 12 are used. The octagonal block 5 can be joined to the column surface 2a and the beam surface 3a via the. These sealing blocks 9 to 12 are also bonded to the column surface 2a and the beam surface 3a with an adhesive, and the octagonal block 5 is also bonded to these sealing blocks 9 to 12 with an adhesive. Even in the fourth embodiment, it can be constructed in the same manner as in the first embodiment, and the same operations and effects can be obtained.

As shown in the figure, on the hypotenuses w opposite to each other of the octagonal block 5, a joining projection 13 and a joining groove 14 are formed along the length direction of the hypotenuse w. Further, on the hypotenuse tw of the isosceles trapezoidal block 6, a joining projection 13 is formed along the length direction of the hypotenuse tw. By fitting the joining groove 14 to the joining protrusion 13, the adjacent octagonal blocks 5 or the adjacent octagonal blocks 5 and the isosceles trapezoidal block 6 can be mechanically joined. Thereby, it can prevent that the blocks 5 and 6 move to the out-of-plane direction of the earthquake-resistant wall 1, and can reinforce structurally.
