Since the shape of this recess 18a is the same as the shape of the recesses 12a and 14a provided in the first protruding plate part 12 and the second protruding plate part 14, a detailed explanation will be given in the description of the recesses 12a and 14a. I will use it.

In the main body member 10 described above, the length in the longitudinal direction, that is, the length from the right side of the first protruding plate part 12 to the left side of the second protruding plate part 14, is the length of the long side of the brick expected to be used. longer than length. Further, the length between the first protruding plate part 12 and the opposing third protruding plate part 18, or the length between the second protruding plate part 14 and the opposing third protruding plate part 18, The length obtained by adding twice the length of the first to third protruding plate parts 12, 14, and 18 in the front-rear direction is approximately equal to the length of the short side of the brick that is expected to be used.

In molding the main body member 10 described above, a plurality of main body members 10 are molded in a joined state, and by separating the main body members 10 from each other, a plurality of main body members can be provided. Specifically, as shown in FIG. 8, the lower front end of the third protruding plate part 18 of one main body member 10 and the lower part of the back surface of the base 11 of the other main body member 10 are connected to a plate-shaped joint. It is joined at 19. By separating the joint portion 19 from both main body members 10, a plurality of main body members 10 can be provided.

A method of using the main body member 10 described above when assembling bricks with mortar will be described below. In the following description, the bricks are assembled in the vertical direction, and the bricks placed on the lower side are referred to as lower bricks, and the bricks placed on the upper side are referred to as upper bricks.

<First usage form>
A usage example according to this usage pattern will be described with reference to FIGS. 9 to 12. Note that in FIGS. 9 to 12, some reference numerals are omitted, and if necessary, reference may be made to FIGS. 1 to 7. In this usage mode, an even number of main body members 10, for example two, are used. In addition, the main body member 10 is cut at the second weakened portion 15 from the right and the fourth weakened portion 15 from the right. As a result, as shown in FIG. 9, the first connecting part 21 includes the first protruding plate part 12 at one end and the third protruding plate part 18 at the other end, and the third protruding plate part 21 at each of both ends. A second connecting portion 22 including a plate portion 18, a third connecting portion 23 having a second protruding plate portion 14 at one end and a third protruding plate portion 18 at the other end are formed. Then, one or more, for example, two of the first to third connecting portions 21 to 23 are used.

First, as shown in FIG. 10, two main body members 10 are arranged with a gap between them so that their back surfaces face each other, and then connected using first to third connecting parts 21 to 23. FIG. 10 shows an example of connection using the first connecting part 21 and the third connecting part 23. The recess 12a provided in the first protruding plate part 12 of the first connecting part 21 is fitted into the first fitting part 16 of one main body member 10, and the third protruding plate of the first connecting part 21 is fitted. The recess 18a provided in the portion 18 is fitted into the second fitting portion 17 of the other main body member 10. Similarly, the recess 14a provided in the second protruding plate portion 14 of the third connecting portion 23 is fitted into the second fitting portion 17 of one main body member 10, and the recess 14a provided in the second protruding plate portion 14 of the third connecting portion The recessed portion 18a provided in the third protruding plate portion 18 is fitted into the first fitting portion 16 of the other main body member 10. Note that the second connecting portion 22 may be used instead of the first connecting portion 21 or the third connecting portion 23, or two of the first to third connecting portions 21 to 23 may be used. Further, the two main body members 10 may be connected by only one of the first to third connecting portions 21 to 23.

Once the auxiliary member is assembled as described above, the auxiliary member is placed on the lower brick 40, as shown in FIG. At this time, the front end portions of the first to third protruding plate portions 12, 14, and 18 are placed so that the positions in the front-rear direction coincide with the respective long side surfaces of the lower brick 40. Then, mortar 50 is filled between the back surfaces of the two main body members 10. At this time, the mortar 50 is filled until the upper surface of the mortar 50 is approximately at the same height as the upper surface of the main body member 10. Subsequently, the auxiliary member is removed from above the lower brick 40. By doing so, the mortar 50 whose width is approximately equal to the distance between the back surfaces of the main body member 10 and whose height is approximately equal to the height of the main body member 10 remains on the lower brick 40. If the length on which the mortar 50 is placed is longer than the main body member 10, the auxiliary member may be moved to the upper surface of the lower brick 40 on which the mortar 50 is not placed, and the operation of placing the mortar 50 may be repeated. . At this time, by positioning the mortar 50 that has already been placed between the main body members 10 of the auxiliary members, the mortar 50 that will be placed later can be integrated with the mortar 50 that has been placed first. This allows mortar 50 of the same width to be extended and placed. Therefore, the mortar 50 can be placed over the entire row of the lower bricks 40 without arranging the auxiliary member over the entire row of the lower bricks 40. Then, as shown in FIG. By stacking the upper bricks 50 on top of the mortar 50, assembly can be performed with joints at regular intervals.

In addition, since the main body member 10 is arranged along the long side of the lower brick 40, it can be referred to as a long side plate part. In addition, since the first to third protruding plate parts 12, 14, 18, the connecting part 13, and the first and second fitting parts 16, 17 have a function of being able to be assembled to each other, the assembly part It can be called. In addition, the pair of long side plates (main body member 10) and the first to third connecting portions 21 to 23 are assembled to each other in a separable manner, and the first to third connecting portions 21 to 23 The width in the direction (longitudinal direction of the long side plate) perpendicular to the connected direction (opposite direction of the long side plate) is the same width as the height of the long side plate in the vertical direction. It can be said that it is continuous. This is because the first to third connecting portions 21 to 23 can be provided by dividing the long side plate portion (main body member 10) using the weakened portion 15 or the like. This means that it is possible to form the auxiliary member shown in FIG. 10 only with the long side plate portion (main body member 10).

In the usage pattern described above, an example was explained in which two main body members 10 are used, but an even number of two or more second main body members 10 may be used, for example, as shown in FIG. 13, four second main body members 10 may be used. . In this example, first, regarding the two main body members 10, the left side surface of the first protruding plate part 12 of one main body member 10 and the right side surface of the second protruding plate part 14 of the other first protruding plate part 10 are The connecting groove 13a of the connecting portion 13 of the other body member 10 is fitted from below into the upper recess 12b of the first protruding plate portion 12 of one body member 10 so as to face and abut. Two pairs of members consisting of a pair of main body members 10 combined in this manner are prepared.

Subsequently, similarly to the above-described usage pattern, the members consisting of the pair of main body members 10 are connected by the first to third connecting portions 21 to 23. Note that although FIG. 13 shows an example in which one first connecting portion 21 and one second connecting portion 23 are used, the first connecting portion 21 and the second connecting portion 23 are not attached. The joint portion 16 and the second fitting portion 17 may also be connected by first to third connecting portions 21 to 23. In this case, the strength of the entire auxiliary member can be improved. Further, the number of main body members 10 may also be six or more.

With the above configuration, the auxiliary member according to this usage pattern has the following effects.

- By filling the mortar 50 between the main body members 10, the mortar 50 with a predetermined width can be provided on the upper surface of the lower brick 40. Therefore, it is possible to prevent the mortar 50 from protruding from the side surface between the upper brick 60 and the lower brick 40 or from sinking inward.

- Since the mortar 50 is filled between the main body members 10 so as to substantially match the height of the main body member 10, the mortar 50 can be provided at a substantially constant height. Therefore, the upper bricks 60 can be assembled horizontally while keeping the height from the lower bricks constant.

- Since the first to third connecting parts 21 to 23 can be formed by cutting the main body member 10 using the weakened part 15, it is possible to form multiple members with different functions using one type of main body member 10. can be provided.

- Since they can be assembled to each other using the first to third protruding plate parts 12, 14, 18 and the connecting part 13, the length of the entire auxiliary member can be adjusted to the required length.

<Second usage form>
A usage example according to this usage pattern will be described with reference to FIGS. 14 and 15. Note that in FIGS. 14 and 15, some reference numerals are omitted, and FIGS. 1 to 7 may be referred to if necessary. In this usage mode, one or more main body members 10 are used. 14 and 15 show an example in which two main body members 10 are used. First, two main body members 10 are connected in the longitudinal direction to form an auxiliary member. Regarding this connection direction, since it is equivalent to another usage example in the first usage pattern, a specific explanation will be used. Subsequently, the main body member 10 is placed on the lower brick 40. In this case, the positions of the front end portions of the first to third protruding plate portions 12, 14, and 18 provided on the main body member 10 in the front-rear direction are aligned with the long side surfaces of the lower bricks 40. Place it in Subsequently, mortar 50 is provided on the upper surface of the lower brick 40 on the back side of the main body member 10. In this case, similarly to the first usage mode, the mortar 50 is provided to a height approximately equal to the upper surface of the main body member.

Subsequently, as shown in FIG. 15, the upper brick 60 is placed on the upper surface of the mortar 50 while the mortar 50 and the auxiliary member consisting of two main body members 10 are placed on the upper surface of the lower brick 40. place In this case, the lower surface of the upper brick 60 not only contacts the upper surface of the mortar 50 but also contacts the upper surface of the auxiliary member, and is supported not only by the mortar 50 but also by the auxiliary member.

After the upper brick 60 is placed, the auxiliary member is removed, resulting in a state similar to the first usage example shown in FIG. 12, and the brick assembly is completed. The auxiliary member may be removed immediately after the upper brick 60 is placed, or may be removed after the mortar 50 has hardened to a certain level of hardness. If this is done after the mortar 50 has attained a certain hardness, it is possible to prevent the mortar 50 from being crushed or leaking due to the weight of the upper bricks 60.

In addition, since the main body member 10 is arranged along the long sides of the lower bricks 40, it can be referred to as a long side plate section, as in the first usage mode. Further, since the tips of the first to third protruding plate sections 12, 14, and 18 are used for positioning with the lower brick 40, the tips can be referred to as alignment sections, and the base of the main body member 10 The upper surface of 11 and the first to third protruding plate portions 12, 14, and 18 support the upper brick 60, and therefore can be referred to as supporting portions.

In the usage pattern described above, the main body member 10 is used only on one long side of the lower brick 40, but it may be used on both long sides. Moreover, instead of arranging the tips of the first to third protruding plate parts 12, 14, 18 so as to match the long side surfaces of the lower bricks 40, the first to third protruding plate parts 12, 14, The positions of the intermediate portions on the back side of the tips of the bricks 18, for example, the recesses 12a, 14a, and 18a, may be arranged to coincide with the long sides of the lower bricks 40.

With the above configuration, the auxiliary member according to this usage pattern has the following effects.

- Since the tips of the first to third protruding plate parts 12, 14, and 18 are used as positioning parts to align with the lower brick 40, the position of the side surface of the mortar 50 can be set at a predetermined position from the side surface of the lower brick 40. Can be at fixed positions separated by a distance

- Since the upper brick 60 is supported by the base 11 and the first to third protruding plate parts 12, 14, and 18 of the main body member 10, the weight of the upper brick 60 placed on the upper surface of the mortar 50 prevents the mortar from being crushed. It is possible to prevent the situation from protruding from the side.

- By cutting the main body member 10 using the weakened part 15 or assembling the main body members 10 using the first to third protruding plate parts 12, 14, 18 and the connecting part 13, The length of the main body member 10 can be changed as necessary.

<Third usage form>
A usage example according to this usage pattern will be described with reference to FIG. 16. In this mode of use, one or more of the first to third connecting portions 21 to 23 used in the first mode of use are used as auxiliary members. FIG. 16 shows an example in which the second connecting portion 22 is used.

First, mortar 50 is placed on the upper surface of the assembled lower bricks 40. When placing the mortar 50 on the upper surface of the lower brick 40, a method equivalent to the first usage pattern or the second usage pattern can be adopted. Subsequently, the first to third connecting parts 21 to 23 are embedded in the mortar 50 and placed on the lower brick 40. In FIG. 16, since the second connecting portion 22 is difficult to visually recognize due to the mortar 50, the drawing of the mortar 50 is omitted. At this time, it is arranged at a position as far away from the long side of the lower brick 40 as possible, specifically, at approximately the center of the lower brick 40 in the width direction. As described in the first embodiment and the second embodiment, the height of the mortar 50 is approximately equal to the width of the base 11 etc. of the main body member 10, so the upper surface of the mortar 50 is connected to the first to third connecting parts 21 to 23. The height is approximately the same as the upper surface, and the front, rear, left, and right surfaces of the first to third connecting portions 21 to 23 are buried by the mortar 50, and only the upper surfaces are visible, or the upper surfaces are also hidden by the mortar 50. It will be covered. After placing the mortar 50, the upper brick 60 is placed in the same manner as in the first usage mode or the second embodiment, thereby completing the brick assembly.

<Fourth usage form>
A usage example according to this usage pattern will be described with reference to FIGS. 17 and 18. In this mode of use, the first to third connecting portions 21 to 23 used in the first mode of use are cut at the weakened portion 15 provided approximately at the center in the longitudinal direction to form a spacer 31 shown in FIG. 17. . This spacer 31 has one of the first to third protruding plate parts 12, 14, 18 provided at one end even when any of the first to third connecting parts 21 to 23 is cut, None of the first to third protruding plate parts 12, 14, and 18 are provided at the other end. Note that FIG. 17 shows an example in which the third protruding plate portion 18 is provided at one end. First to third connecting portions 21 to 23 An example in which the second connecting portion 22 is used is shown.

In the usage example according to this usage mode, the spacer 31 is used after the mortar 50 has been placed on the lower brick 40. The mortar 50 may be placed in the same manner as in the first usage form or the second usage form, and if it is carried out in the same manner as in the second usage form, when the spacer 31 is used, the main body member 10 may be placed on the mortar 50. This means that it remains on the side of the Further, as in the third usage mode, the first to third connecting parts 21 to 23 may be embedded in the mortar 50.

After one upper brick 60 is placed on the mortar 50, the spacer 31 is arranged so that its back surface is in contact with the mortar 50 and one of its upper and lower ends is in contact with the side surface of the short side of the upper brick 60. That is, any one of the first to third protruding plate parts 12, 14, and 18 included in the spacer 31 is placed so as to face upward. Once the spacer 31 is placed, another upper brick 60 is placed so as to sandwich the spacer 31 therebetween and contact the other of the upper and lower ends of the spacer 31. By doing so, the interval between the upper bricks 60 can be maintained equal to the vertical width of the spacer. After another upper brick 60 is placed, mortar 50 is poured between the upper bricks 60. In addition, when pouring the mortar 50 between the upper bricks 60, the main body member 10 may be brought into contact between the upper bricks 60 to suppress outflow of the mortar 50.

On the other hand, instead of placing the spacer 31 on the mortar 50, the spacer 31 is embedded in the mortar 50 before or after placing the mortar 50 so that the back side of the spacer 31 comes into contact with the upper surface of the lower brick 40. It can also be used as a thing. Even in this case, the protruding length of the first to third protruding plate parts 12, 14, and 18 from the back surface of the spacer 31 is formed to be larger than the vertical width of the spacer 31, that is, the height of the mortar 50 serving as the joint. The tips of the first to third protruding plate parts 12, 14, and 18 can protrude without being buried in the mortar 50, and can be brought into contact with the short-side side surface of the upper brick 60.

With the above configuration, the auxiliary member in this usage mode has the following effects.

- When using the auxiliary member to maintain a constant interval between joints between adjacent building materials, the auxiliary member can be placed without protruding above the upper surface of the building material.

- Since the first to third protruding plate parts 12, 14, 18 are shorter than the height of the upper brick 60, a situation where the first to third protruding plate parts 12, 14, 18 protrude higher than the upper brick is prevented. Can be suppressed.
