Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of masonry construction of a horizontal hole ceramic block for construction having a cavity serving as a horizontal hole passing through the left and right sides.

Conventionally, the above-mentioned horizontal hole ceramic blocks do not have vertical holes, so they are built in a potato-jointed manner, so the load from above is not widely distributed downwards, so it is more difficult to assemble than in the case of horse-jointed (broken joint) masonry. There was a drawback that the strength decreased and the appearance of the joints became monotonous.

An object of the present invention is to form a recess in at least one of the left and right side surfaces of a horizontal hole ceramic block, and to make the recess deeper than a predetermined depth of cover for vertical stripes of mortar or the like, thereby reducing the depth of cover. By shifting the vertical joints left and right in the upper and lower tiers within the range exceeding the depth, the purpose is to enable masonry to be carried out in a horse-riding joint manner.

Another object of the present invention is to prevent the filling material such as mortar filled into the recess from flowing into the cavity even if the openings on the left and right sides are not closed with pads as in the conventional case.

The illustrated embodiment will be described below.

A ₁ to _{A 6} are different horizontal hole ceramic blocks used in the practice of the present invention.

First, the horizontal hole ceramic block _A1 is integrally formed by extrusion molding and fired at high temperature, and has a substantially horizontally long rectangular parallelepiped shape.
are vertical, and the upper and lower web shells 2, 2 are curved downward and upward, respectively, and are provided with recesses 3, 3 for arranging transverse reinforcement.

Further, the left and right ends of these web shells 2, 2 are hollowed out into a substantially semicircular shape curved to the right and left, respectively, and recesses 4, 4 for arranging vertical reinforcements (to be described later) are symmetrically provided on the left and right sides. There is.

The recesses 4, 4 have a depth equivalent to approximately twice the predetermined cover thickness 6 (for example, 20 mm according to the Building Standards Act) of concrete or mortar for the vertical reinforcement 5.
D has ₁ .

b ₁ to _{b 4} are horizontal holes penetrating through the left and right side surfaces, respectively, and these cavities are formed around the face shells 1, 1 and web shells 2, 2 and are formed between the web shells 2, 2. The central partition wall 7 and the partition walls 8 and 9 located between the partition wall 7 and the face shells 1 and 1 form a vertically elongated shape that is divided into approximately four equal parts, and the cavity b ₁ and
b ₄ , cavities b ₂ and b ₃ are arranged symmetrically.

Reference numeral 10 denotes a regulating portion protrudingly provided by extrusion molding over the entire length reaching the left and right opening ends of each cavity b ₁ to _{b 4} ;
It is formed into a protrusion with a rectangular cross section, and one protrusion is provided in each of the cavities b ₂ and b ₃ horizontally along the center of the side surface of the partition wall 7, and three protrusions are provided in each of the cavities b ₁ and b ₄ . They are provided horizontally protruding from the side surfaces of the face shells 1, 1 at equal intervals from each other.

The left and right openings of the cavities b ₂ and b ₃ have narrower opening widths at the restricting portion 10, as if the restricting portion 10
The opening is constricted at the point where it is essentially partitioned into two small sections, upper and lower.

In addition, the opening width of the cavities b ₁ and b ₄ becomes narrow at the portions of the regulating portions 10 where the left and right openings are three, as if constricted at these regulating portions 10 and the openings were substantially partitioned into four smaller portions, upper and lower. It is becoming a state.

In order to assemble the above-mentioned horizontal hole ceramic blocks A ₁ at the horse joints, a plurality of them are placed on the base 11 on which the vertical reinforcements 5 are planted at the required intervals, and the vertical joints of each other are arranged approximately at the upper and lower levels. Depth of recesses 4, 4 D ₁
The masonry is assembled by making the joints shifted to the left and right by an amount of , and positioning each vertical strip 5 in the center of one of the left and right opposing recesses 4, 4 (Fig. 5). .

Then, when mortar is filled in the recesses 4, 4 where the vertical reinforcements 5 are arranged, each cavity b ₁ to b ₄ is filled as described above.
In addition to the fact that the opening is constricted at the regulating part 10 and is essentially partitioned into two or four small parts, due to the originally low fluidity of mortar, there is a A small amount of mortar flows into the area, gets stuck there, becomes clogged, and solidifies, but does not flow inward any further, and the mortar filled in this way provides a predetermined covering thickness for the vertical reinforcements 5. .

Furthermore, the mortar that has flowed into the area immediately inside the opening of each of the cavities b ₁ to _{b 4} will flow into the face shells 1, 1, web shells 2, 2, partition walls 7, 8, 9, regulating portion 10, etc. Since it solidifies, the contact area between the mortar of the reinforcing bar portion and the horizontal hole ceramic block _A1 increases accordingly, and the bond between the two is strengthened.

Next, the horizontal hole ceramic block _A2 in Fig. 6 is
The horizontal hole ceramic block _A1 is different from the above-mentioned horizontal hole ceramic block A1 in the depth of the recesses 12, 12 in which the vertical reinforcements are placed, but the other configurations are the same.

That is, the depth of the recesses 12, 12 corresponds to about three times the predetermined cover thickness 6 of mortar, etc., and corresponds to about one-third of the length L of the horizontal hole ceramic block _A2 . There is.

In order to assemble this horizontal hole ceramic block _A2 , a plurality of them are placed on a base 14 on which vertical reinforcements 13 are planted at required intervals, and the vertical joints of the horizontal hole ceramic blocks A 2 are placed in the upper and lower tiers. Block A ₂ has a concave portion 1 that is shifted left and right by half the length L, and has each longitudinal strip 13 facing left and right.
The recesses 12, 12 are placed at a distance corresponding to one-third of the depth from the inner end of one of the recesses 12 among the recesses 2, 12, and the vertical reinforcements 13 are arranged. Fill the area with mortar.

The horizontal hole ceramic block A ₃ (FIG. 7) is different from the horizontal hole ceramic blocks A ₁ and A ₂ in the depths of the recesses 15 and 16 for arranging the vertical reinforcements, but the other configurations are the same.

That is, the recess 15 has the predetermined cover thickness 6.
(20 mm), and the recess ₁₆ has a depth D ₃ corresponding to approximately twice the predetermined cover thickness 6.

In order to assemble this horizontal hole ceramic block A ₃ , a plurality of them are placed on a base 18 on which vertical reinforcements 17 are planted at a required interval, and each vertical joint is approximately formed in the recess 16 at the upper and lower levels. The state of the one-horse tread joint is shifted left and right by the depth D ₃ , and each vertical line 17
Of the recesses 15 and 16 facing left and right, the recess 16
The recesses 16 facing the recesses 15 in which the vertical reinforcements 17 are arranged are filled with mortar (Fig. 8).

The horizontal hole ceramic block A ₄ (Fig. 9) is
The horizontal hole ceramic blocks _A1 to _A3 are different in the combination of depths of recesses 19 and 20 in which vertical reinforcements are placed, but otherwise have the same configuration.

That is, the depth of the recess 19 corresponds to about three times the predetermined cover thickness 6 (20 mm), and the depth of the recess 20 is the same as the predetermined cover thickness 6.

This horizontal hole ceramic block A ₄ is mounted on a base 22 in which a plurality of vertical reinforcements 21 are planted at a required interval, and the length of this horizontal hole ceramic block A ₄ is set so that the vertical joints of each other are in the upper and lower tiers. The state of the true horse tread joint is shifted to the left and right by half of the length L, and each vertical strip 21 is spaced from the inside of the recess 20 of the recesses 19 and 20 facing left and right at intervals corresponding to one-third of the depth thereof. The recesses 20 facing the recesses 19 with the vertical reinforcements 21 are filled with mortar (FIG. 9).

Next, the horizontal hole ceramic block _A5 in Fig. 10.
What is the horizontal hole ceramic block A ₁ to _{A 4} ?
The difference is that the recesses 23 for arranging vertical reinforcements are provided only on one side of the left and right sides, for example, on the right side, and the left side is vertical, but the other configurations are the same.

The recess 23 has the predetermined cover thickness 6 (20 mm).
The depth D4 is approximately twice as large as the depth _D4 .

In order to assemble these horizontal hole ceramic blocks _A5 , a required number of them are placed on a base 25 with vertical reinforcements 24 planted at required intervals, and recesses 23
The direction of the vertical strips 24 is reversed from left to right, and each vertical joint is placed on the upper and lower tiers in a state where the vertical joints are shifted to the left and right by approximately the depth D ₄ of the recess 23. The masonry is placed in the center, and the recessed portion 23 where the longitudinal reinforcement 24 is arranged is filled with mortar (FIG. 11).

The horizontal hole ceramic block A ₆ shown in FIG. 12 has a recess 26 for reinforcing only on one of the left and right sides, similar to the above-mentioned horizontal hole ceramic block A ₅ , but the depth is different, and the other The configuration is the same.

That is, the depth of the recess 26 corresponds to about three times the predetermined cover thickness 6 (20 mm) of the mortar or the like.

In order to assemble this horizontal hole ceramic block A ₆ , a required number of horizontal holes are placed on a base 28 on which vertical reinforcements 27 are planted at required intervals, and the direction of the recesses 26 is reversed from left to right in each vertical direction. Mount this horizontal hole ceramic block A ₆ in a state where the vertical joints are shifted left and right by half the length L of the horizontal hole ceramic block A 6 in the upper and lower rows, and insert each vertical strip 27 from the inner end of the recess 26 to its depth. They are stacked at intervals corresponding to one third, and the recesses 26 where the vertical reinforcements 27 are arranged are filled with mortar.

As is clear from the above description, according to the present invention, a recess is formed in at least one of the left and right side surfaces of a horizontal hole ceramic block, and the depth of the recess is adjusted to a predetermined covering thickness with respect to the vertical strips of mortar or the like. The depth exceeds the specified cover thickness, so by placing vertical reinforcements at desired locations within that range, and shifting the vertical joints left and right in the upper and lower tiers, the depth exceeds the specified cover thickness. It is possible to construct a wall with a variety of horse joints ranging from a corresponding length to half the length of the horizontal hole ceramic block, that is, from a single horse step joint to a true horse step joint as shown in the actual example. .

Further, in the horizontal hole ceramic block used in the present invention, the horizontal hole surrounded by the face shells 1, 1 and the web shells 2, 2 is connected to the partition walls 7, 8, 9.
It is partitioned into four cavities b ₁ to b ₄ by , and the inner wall surface of each cavity b ₁ to _{b 4} is regulated by extrusion molding over the entire length reaching the left and right opening ends of each cavity b ₁ to _{b 4} . Since the portion 10 is provided protrudingly, thereby reducing the opening area of the left and right opening ends, mortar etc. filled into the recessed portion after placing the vertical reinforcements is naturally low in fluidity. However, it does not flow deep into cavities _b1 to _b4 .

That is, some mortar and the like flows just inside the opening edge, but becomes clogged there. Therefore, there is no need to use a pad for closing the opening as in the conventional case.

Furthermore, it is clear that the partition walls 7, 8, 9 are advantageously used to increase the strength of the entire block.
