Summary of the Invention

Problems to be Solved by the Invention

[0004] Although the interval between the bricks described in Patent Document 1 can be made constant, the finish of joints other than the interval between the bricks is not considered.

[0005] [[ID=X39]]The present invention has been made to solve the above problems, and its main object is to provide an auxiliary member capable of improving the working efficiency when assembling block-shaped building materials in the shape of a rectangular parallelepiped such as bricks with mortar, and a construction method.

Means for Solving the Problems

[0006] The first configuration is an auxiliary member used when assembling rectangular block-shaped building materials with mortar, comprising: a pair of long-side plate sections placed along the long sides on the upper surface of a lower building material, which is located at the bottom when stacking the building materials vertically; and a connecting section that positions the pair of long-side plate sections at an inner interval narrower than the width of the short side of the lower building material, wherein the long-side plate sections have a predetermined height, and the connecting section is connected to the long-side plate sections at a position spaced apart from the lower building material.

[0007] In the first configuration, mortar can be filled between the long-side plate sections, allowing a predetermined width of mortar to be provided on the upper surface of the lower building material. Therefore, it is possible to prevent the mortar from overflowing from the sides of the rectangular block-shaped building material or from sinking inward.

[0008] The second configuration, in addition to the first configuration, has the long side plate portion having a predetermined height that extends continuously along the longitudinal direction, and the connecting portion is located above the upper end of the long side plate portion.

[0009] In the second configuration, mortar is filled between the long-side boards so that it is approximately the same height as the long-side boards, thereby providing a mortar layer of approximately constant height. Therefore, the building materials can be assembled horizontally while maintaining a constant height.

[0010] The third configuration, in addition to the first or second configuration, includes a pair of long-side plate portions that protrude perpendicularly from the opposite side to the opposing side and are alignable with the side of the long side along which the lower building material is placed.

[0011] In the third configuration, the position of at least one side of the mortar can be set to a fixed position at a predetermined distance from the side of the lower building material, or the center of the placed mortar can be aligned with the center of the lower building material.

[0012] The fourth configuration is a construction method for assembling block-shaped building materials with mortar using auxiliary members of any of the first to third configurations, comprising the steps of: placing the auxiliary member described in claim 1 or claim 2 on the upper surface of the lower building material; placing the mortar between the long-side plate portions on the upper surface of the lower building material; removing the auxiliary member from the upper surface of the lower building material; and placing the building material on the upper surface of the mortar.

[0013] In the fourth configuration, a construction method can be provided in which building materials are assembled with mortar using auxiliary members related to any of the first to third configurations.

[0014] The fifth configuration, in addition to the fourth configuration, includes the step of placing the mortar, which involves positioning a portion of the already placed mortar between the long-side plate sections, placing the auxiliary member on the upper surface of the lower-stage building material at a position shifted in the direction of the arrangement of the lower-stage building material, and placing the mortar between the long-side members.

[0015] In the fifth configuration, mortar of the same width can be placed in the direction of the arrangement of building materials so as to become one with the already placed mortar. Therefore, mortar can be placed over the entire direction of the arrangement of lower building materials without having to place auxiliary members over the entire direction of the arrangement of lower building materials.

[0016] The sixth configuration is an auxiliary member used when assembling block-shaped building materials with mortar, and has a pair of long-side plate portions that are placed along the long side on the upper surface of a lower building material, which is a building material located in the lower layer, when stacking the building materials, and the long-side plate portions include an alignment portion for aligning with the side of the long side along which the lower building material is placed, and a support portion having a predetermined height and capable of supporting an upper building material, which is a building material located in the upper layer when stacking the building materials.

[0017] In the sixth configuration, the position of the mortar's side is set at a fixed position a predetermined distance away from the side of the lower building material, while preventing the mortar from collapsing due to the weight of the upper building material placed on top of it.

[0018] In the seventh configuration, in addition to the sixth configuration, the long-side plate portion projects orthogonally from a surface extending in the longitudinal direction, and includes a plurality of projecting plate portions having the same height as the support portion, and a tip end portion or an intermediate portion of the projecting plate portion is the alignment portion.

[0019] In the seventh configuration, both the function of the alignment portion and the function of the support portion in the sixth configuration can be realized by the projecting plate portion.

[0020] In the eighth configuration, in addition to the sixth or seventh configuration, irregularities are provided on a side of the long-side plate portion that abuts on the mortar.

[0021] In the eighth configuration, the side surface of the mortar can be decorated using the irregularities.

[0022] The ninth configuration is a construction method of assembling block-shaped building materials with mortar using an auxiliary member of any one of the sixth to eighth configurations. The method includes aligning with the alignment portion with respect to the long side of the lower building material, placing an auxiliary member of any one of the sixth to eighth configurations on an upper surface of the lower building material, placing the mortar on the upper surface of the lower building material, placing the upper building material on upper surfaces of the mortar and the support portion, and detaching the auxiliary member.

[0023] In the ninth configuration, a construction method of assembling building materials with mortar using an auxiliary member according to any one of the sixth to eighth configurations can be provided.

[0024] In the tenth configuration, in addition to any one of the first to third, sixth to eighth configurations, the long-side plate portion includes a weakened portion that is provided at intervals in the longitudinal direction and has a lower strength than other portions.

[0025] In the tenth configuration, the length of the long-side plate portion can be changed as needed.

[0026] In the 11th configuration, in addition to any of the configurations of the 1st to 3rd, 6th to 8th, and 10th, the long-side plate portion includes assembling portions that can be assembled to each other.

[0027] In the 11th configuration, by assembling the long-side plate portions, a longer auxiliary member can be obtained. Further, by adding the 11th configuration to the 10th configuration, the member cut at the weakened portion can be used as a connecting portion.

[0028] The 12th configuration is an auxiliary member used when assembling block-shaped building materials with mortar, and includes a long plate-shaped base portion whose width is the width of the joint formed by the mortar, and a protruding plate portion that protrudes from at least one in the thickness direction of the base portion and whose width is equal to the width of the base portion. The base portion includes a weakened portion that is provided at intervals in the longitudinal direction and has a lower strength than other portions.

[0029] In the 12th configuration, it can be cut using the weakened portion and then embedded in the joint, and the interval between the building materials can be defined so that the width of the joint is constant using the base portion and the protruding plate portion.

[0030] The 13th configuration, in addition to the 12th configuration, the protruding length of the protruding plate portion from the base portion is shorter than the interval between adjacent weakened portions. ? [[ID=;]]

[0031] In the 13th configuration, when the base portion abuts on the upper surface of the lower building material and the protruding plate portion stands upright upward, the stability can be improved.

[0032] The 14th configuration, in addition to the 12th or 13th configuration, the protruding length of the protruding plate portion from the base portion is smaller than the thickness in the stacking direction of the building materials.

[0033] ? In the 14th configuration, when the auxiliary member is used to keep the interval of the joint between adjacent building materials constant, the auxiliary member can be arranged without protruding above the upper surface of the building materials.

[0034] The 15th configuration is characterized in that, in addition to any of the 12th to 14th configurations, the distance between adjacent weakened portions is smaller than the length of the long side of the building material.

[0035] In the 15th configuration, the length of the auxiliary member can be made shorter than the length of the long side of the building material, so that the auxiliary member can be placed on a single building material without it overhanging.

[0036] The 16th configuration is provided with two of the aforementioned protruding plate portions facing each other, in addition to any of the 12th to 15th configurations, with the aforementioned weakening portion in between.

[0037] In the 16th configuration, when the base is cut using the weakened section, protruding plate sections are located at both ends, which improves stability when erected.

[0038] The 17th configuration is provided with, in addition to any of the 12th to 16th configurations, an assembly portion that can be assembled to each other on at least one of the base portion and the protruding plate portion.

[0039] In the 17th configuration, the structure can be modified using the assembly section if the weakened section is cut or otherwise used for other purposes. [Brief explanation of the drawing]

[Modes for carrying out the invention]

[0041] The auxiliary member according to this embodiment is used when assembling block-shaped building materials, such as bricks, which are rectangular parallelepipeds, with mortar to form flower beds, fireplaces, block walls, etc. First, the shape of the main body member 10 that constitutes the auxiliary member according to this embodiment will be described with reference to Figures 1 to 7. The main body member 10 is made of hard plastic and has an overall shape of a long plate. The main body member 10 will be described with the thickness direction as the front-to-back direction, the width direction as the up-and-down direction, and the length direction as the left-to-right direction.

[0042] The main body member 10 has a rectangular base portion 11 that has a constant thickness and width and extends in the left-right direction. A rectangular plate-shaped first protruding plate portion 12 is provided at the right end of the base portion 11, projecting vertically forward. The width of this first protruding plate portion 12 in the vertical direction is approximately equal to the width of the base portion 11, the thickness in the left-right direction is approximately equal to the thickness of the base portion 11, and the length in the front-rear direction is slightly longer than the vertical width. Near the front end of the first protruding plate portion 12, a recess 12a is provided that is recessed in a roughly rectangular shape from below to above. The front-rear width of this recess 12a narrows slightly as it goes upward, and the bottom is approximately horizontal to the bottom surface of the first protruding plate portion 12. On the other hand, near the rear end of the first protruding plate portion 12, an upper recess 12b is provided that is recessed in a roughly rectangular shape from above to below. The front-to-back width of this upper recess 12b is approximately equal to and constant with the thickness of the base 11, and its lower end is approximately horizontal to the lower surface of the first protruding plate portion 12.

[0043] At the left end of the base portion 11, a connecting portion 13 is provided, which protrudes forward from the front surface of the base portion 11, has a thickness equivalent to that of the base portion 11 in the front-rear direction, and a width equivalent to that of the base portion 11 in the vertical direction. This connecting portion 13 is provided with a rectangular connecting groove 13a that is recessed from below to above. The left-right width of this connecting groove 13a is approximately the same as the thickness of the base portion 11, and its lower end is approximately horizontal to the upper surface of the connecting portion 13a.

[0044] A second protruding plate portion 14 is provided at the left end of the connecting portion 13, sharing its left end and rear end with the connecting portion 13. The width of this second protruding plate portion 14 in the vertical direction is approximately equal to the width of the base portion 11, the thickness in the left-right direction is approximately equal to the thickness of the base portion 11, and the length in the front-rear direction is slightly longer than the vertical width. The length of the front end of the second protruding plate portion 14 from the back surface of the base portion 11 is equal to the length of the first protruding plate portion 12 from the back surface of the base portion 11. Near the front end of the second protruding plate portion 14, a recess 14a is provided, which is recessed in a roughly rectangular shape from bottom to top. The front-rear width of this recess 14a narrows slightly towards the top, and its bottom is approximately horizontal to the top surface of the first protruding plate portion 14. The position of the recess 14a in the front-rear direction is equal to the position of the recess 12a in the first protruding plate portion 12 in the front-rear direction.

[0045] The base 11 has five wedge-shaped weakened sections 15 that are recessed from front to rear and are provided at equal intervals in the left-right direction. These weakened sections 15 extend vertically in the up-down direction, have a uniform cross-sectional shape in the up-down direction, and their width in the left-right direction gradually narrows towards the rear. In other words, these weakened sections 15 have reduced strength compared to other parts of the base 11.

[0046] Between the first protruding plate portion 12 and the rightmost weakened portion 15, a first fitting portion 16 is provided, which protrudes forward from the front surface of the base portion 11. The first fitting portion 16 protrudes vertically forward from the front surface of the base portion 11 by an amount equal to the thickness of the base portion 11, and then bends vertically to the left from that position. At the left end of this first fitting portion 16, a return 16a is provided that is widened toward the rear side, and the distance between the return 16a and the vertically protruding portion of the first fitting portion 16 is approximately equal to the width between the front end of the first protruding plate portion 12 and the front surface of the recess 13 of the first protruding plate portion 12.

[0047] Between the second protruding plate portion 14 and the leftmost weakened portion 15, a second fitting portion 17 is provided, which has a shape symmetrical to the first fitting portion 16. That is, the second fitting portion 17 protrudes vertically forward from the front surface of the base portion 11 by an amount equal to the thickness of the base portion 11, and then bends vertically to the right from that position, with a return 17a provided at its right end.

[0048] On either side of the second weakened portion 15 from the right and the second from the left, rectangular plate-shaped third protruding plate portions 18 are provided, projecting vertically forward. The distance between each weakened portion 15 and the adjacent third protruding plate portion is equal and approximately equal to the width of the base portion 11, etc. The width of this third protruding plate portion 18 in the vertical direction is approximately equal to the width of the base portion 11, the thickness in the horizontal direction is approximately equal to the thickness of the base portion 11, and the length in the front-to-back direction is approximately equal to the length of the first protruding plate portion 12 in the front-to-back direction. Near the front end of the third protruding plate portion 18, a recess 18a is provided, which is recessed in a roughly rectangular shape from below to above. The shape of this recess 18a is the same as the shape of the recesses 12a and 14a provided in the first protruding plate portion 12 and the second protruding plate portion 14, so a specific explanation will refer to the explanation of recesses 12a and 14a.

[0049] 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 portion 12 to the left side of the second protruding plate portion 14, is longer than the length of the long side of the brick that is expected to be used. Furthermore, the length between the first protruding plate portion 12 and the third protruding plate portion 18 facing it, or the length between the second protruding plate portion 14 and the third protruding plate portion 18 facing it, plus twice the length of the front-to-back length of the first to third protruding plate portions 12, 14, and 18, is approximately equal to the length of the short side of the brick that is expected to be used.

[0050] In molding the main body member 10 as described above, the molding is performed with multiple main body members 10 joined together, and multiple main body members can be provided by separating the main body members 10 from each other. Specifically, as shown in Figure 8, the lower part of the front end of the third protruding plate portion 18 of one main body member 10 and the lower part of the back surface of the base portion 11 of the other main body member 10 are joined by a plate-shaped joint portion 19. Then, by separating this joint portion 19 from both main body members 10, multiple main body members 10 can be provided.

[0051] The method of using the main body component 10 described above when assembling bricks with mortar will be explained below. In the following explanation, the bricks will be assembled in an up-and-down direction, with the bricks placed on the lower side being referred to as lower bricks and the bricks placed on the upper side being referred to as upper bricks.

[0052] <First usage form> An example of use relating to this configuration will be explained with reference to Figures 9 to 12. Note that some reference numerals have been omitted in Figures 9 to 12; if necessary, please refer to Figures 1 to 7. In this configuration, an even number of main body members 10 are used, for example, two. In addition, the main body members 10 are 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 Figure 9, a first connecting portion 21 is formed with a first protruding plate portion 12 at one end and a third protruding plate portion 18 at the other end; a second connecting portion 22 is formed with a third protruding plate portion 18 at each end; and a third connecting portion 23 is formed with a second protruding plate portion 14 at one end and a third protruding plate portion 18 at the other end. Then, one or more of these first to third connecting portions 21 to 23, for example, two, are used.

[0053] First, as shown in Figure 10, two main body members 10 are placed with a gap between them so that their backs face each other, and then connected using the first to third connecting parts 21 to 23. Figure 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 recess 18a provided in the third protruding plate part 18 of the first connecting part 21 is fitted into the second fitting part 17 of the other main body member 10. Similarly, the recess 14a provided in the second protruding plate part 14 of the third connecting part 23 is fitted into the second fitting part 17 of one main body member 10, and the recess 18a provided in the third protruding plate part 18 of the third connecting part 23 is fitted into the first fitting part 16 of the other main body member 10. Furthermore, the second connecting part 22 may be used instead of the first connecting part 21 or the third connecting part 23, or any two of the first to third connecting parts 21 to 23 may be used. Also, the two main body members 10 may be connected by only one of the first to third connecting parts 21 to 23.

[0054] Once the auxiliary members are assembled as described above, place them on top of the lower bricks 40 as shown in Figure 11. At this time, the front-to-back positions of the front ends of the first to third protruding plate sections 12, 14, and 18 should be aligned with the respective long sides of the lower bricks 40. Then, fill the space between the backs of the two main body members 10 with mortar 50. Fill the space until the top surface of the mortar 50 is approximately equal in height to the top surface of the main body members 10. Next, remove the auxiliary members from the lower bricks 40. This leaves mortar 50 on the lower bricks 40 with a width approximately equal to the distance between the backs of the main body members 10 and a height approximately equal to the height of the main body members 10. If the length over which the mortar 50 is to be placed is longer than the main body members 10, move the auxiliary members to the top surface of the lower bricks 40 where the mortar 50 is not placed, and repeat the process of placing the mortar 50. At this time, if the mortar 50 already placed is positioned between the main body members 10 of the auxiliary members, the mortar 50 to be placed later can be integrated with the mortar 50 placed earlier, thereby extending and placing mortar 50 of the same width. Therefore, without arranging the auxiliary members to cover the entire direction of the lower bricks 40, mortar 50 can be placed over the entire direction of the lower bricks 40. After that, as shown in Figure 12, by stacking the upper bricks 50 on top of the mortar 50, it is possible to assemble the bricks with joints at regular intervals.

[0055] Furthermore, the main body member 10 is positioned along the long side of the lower brick 40 and can therefore be referred to as the long side plate section. In addition, the first to third protruding plate sections 12, 14, 18, the connecting section 13, and the first and second fitting sections 16, 17 have the function of being able to be assembled with each other and can therefore be referred to as the assembly section. Moreover, the pair of long side plate sections (main body member 10) and the first to third connecting sections 21 to 23 are detachably assembled with each other, and the width of the first to third connecting sections 21 to 23 in the direction perpendicular to the direction in which they are connected (the opposing direction of the long side plate sections) (the longitudinal direction of the long side plate sections) is the same width as the vertical height of the long side plate sections and is continuous along the longitudinal direction. This means that by dividing the long-side plate section (main body member 10) using the weakened section 15, etc., it is possible to provide the first to third connecting sections 21 to 23, which means that it is possible to form the auxiliary member shown in Figure 10 using only multiple long-side plate sections (main body members 10).

[0056] In the usage configuration described above, an example using two main body members 10 was explained, but two or more even numbers, for example, four second main body members 10 as shown in Figure 13, may also be used. In this example, first, for the two main body members 10, the connecting groove 13a of the connecting portion 13 of the other main body member 10 is fitted from below into the upper recess 12b of the first protruding plate portion 12 of one main body member 10, so that the left side surface of the first protruding plate portion 12 of one main body member 10 and the right side surface of the second protruding plate portion 14 of the other first protruding plate portion 10 are in contact with each other. Two pairs of members consisting of a pair of main body members 10 combined in this way are prepared.

[0057] Next, similar to the usage configuration described above, the member consisting of a pair of main body members 10 is connected by the first to third connecting parts 21 to 23. Although Figure 13 shows an example in which one first connecting part 21 and one second connecting part 23 are used, the first fitting part 16 and the second fitting part 17, which are not fitted with any of the first to third connecting parts 21 to 23, may also be connected by the first to third connecting parts 21 to 23. In this case, the overall strength of the auxiliary member can be improved. Furthermore, the number of main body members 10 may be six or more.

[0058] With the above configuration, the auxiliary components for this usage configuration provide the following effects.

[0059] By filling the gaps between the main body members 10 with mortar 50, a predetermined width of mortar 50 can be provided on the upper surface of the lower bricks 40. Therefore, it is possible to prevent the mortar 50 from overflowing from the sides between the upper bricks 60 and the lower bricks 40 or from sinking inward.

[0060] Since the mortar 50 is filled between the main body members 10 so as to be approximately the same height as the main body members 10, it is possible to provide mortar 50 at approximately a constant height. Therefore, the upper bricks 60 can be assembled horizontally while maintaining a constant height from the lower bricks.

[0061] 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, multiple members with different functions can be provided using one type of main body member 10.

[0062] Since the first to third protruding plate sections 12, 14, and 18 and the connecting section 13 can be assembled together, the overall length of the auxiliary member can be adjusted to the required length.

[0063] <Second usage form> An example of use relating to this configuration will be explained with reference to Figures 14 and 15. Note that some reference numerals have been omitted in Figures 14 and 15; if necessary, please refer to Figures 1 to 7. In this configuration, one or more main body members 10 are used. Figures 14 and 15 show an example in which two main body members 10 are used. First, the two main body members 10 are connected in the longitudinal direction to form an auxiliary member. The direction of this connection is the same as in another example of use in the first configuration, so the specific explanation will be used. Next, the main body member 10 is placed on the lower brick 40. In this case, the front-to-back positions of the front-side ends of the first to third protruding plate portions 12, 14, and 18 provided on the main body member 10 are aligned with the long side of the lower brick 40. Next, mortar 50 is applied to the upper surface of the lower brick 40 on the back side of the main body member 10. In this case, as in the first configuration, the mortar 50 is applied to a height approximately equal to the upper surface of the main body member.

[0064] Next, as shown in Figure 15, with the auxiliary members consisting of two main body members 10 placed on the upper surface of the lower brick 40 in addition to the mortar 50, the upper brick 60 is placed on the upper surface of the mortar 50. In this case, the lower surface of the upper brick 60 is in contact with the upper surface of the mortar 50 as well as the upper surface of the auxiliary members, and is supported by the auxiliary members in addition to the mortar 50.

[0065] After the upper bricks 60 are placed, the auxiliary members are removed to achieve a state equivalent to the example shown in Figure 12 of the first usage form, and the brick assembly is completed. The removal of these auxiliary members may be done immediately after the upper bricks 60 are placed, or it may be done after the mortar 50 has hardened to a certain degree. If it is done after the mortar 50 has hardened to a certain degree, it is possible to prevent the mortar 50 from being crushed or leaking out due to the weight of the upper bricks 60.

[0066] Furthermore, since the main body member 10 is positioned along the long side of the lower brick 40, it can be referred to as the long side plate, similar to the first usage configuration. In addition, the tips of the first to third protruding plate portions 12, 14, and 18 are used for alignment with the lower brick 40, and therefore these tips can be referred to as alignment portions. The upper surface of the base portion 11 of the main body member 10 and the first to third protruding plate portions 12, 14, and 18 support the upper brick 60, and therefore can be referred to as support portions.

[0067] In the above-described usage configuration, the main body member 10 is used only on one of the longer sides of the lower brick 40, but it may also be used on both longer sides. Furthermore, instead of positioning the tips of the first to third protruding plate portions 12, 14, and 18 to coincide with the longer side surface of the lower brick 40, the intermediate portions on the rear side of the tips of the first to third protruding plate portions 12, 14, and 18, for example, the recesses 12a, 14a, and 18a, may be positioned to coincide with the longer side surface of the lower brick 40.

[0068] With the above configuration, the auxiliary components for this usage configuration provide the following effects.

[0069] The tips of the first to third protruding plate sections 12, 14, and 18 are used as alignment sections to align with the lower brick 40, so that the side surface of the mortar 50 can be positioned at a fixed position a predetermined distance away from the side surface of the lower brick 40.

[0070] - The base 11 and the first to third protruding plate portions 12, 14, and 18 of the main body member 10 support the upper brick 60, which prevents the mortar from collapsing and overflowing from the sides due to the weight of the upper brick 60 placed on the upper surface of the mortar 50.

[0071] The length of the main body member 10 can be changed as needed by using the weakened portion 15 to cut the main body member 10, or by using the first to third protruding plate portions 12, 14, 18 and the connecting portion 13 to assemble the main body members 10 together.

[0072] <Third usage form> An example of use relating to this configuration will be explained with reference to Figure 16. In this configuration, one or more of the first to third connecting parts 21 to 23 used in the first configuration are used as auxiliary members. Figure 16 shows an example in which the second connecting part 22 is used.

[0073] First, mortar 50 is placed on the top surface of the assembled lower bricks 40. The same method as in the first or second usage configuration can be used to place the mortar 50 on the top surface of the lower bricks 40. Next, the first to third connecting parts 21 to 23 are embedded in the mortar 50 and placed on the lower bricks 40. In Figure 16, the second connecting part 22 is difficult to see due to the mortar 50, so the drawing of the mortar 50 is omitted. At this time, the connecting parts should be positioned as far away from the long side of the lower bricks 40 as possible, specifically, approximately in the center in the width direction of the lower bricks 40. As described in the first and second embodiments, the height of the mortar 50 is approximately equal to the width of the base 11 of the main body member 10. Therefore, the upper surface of the mortar 50 is approximately equal in height to the upper surface of the first to third connecting parts 21 to 23. The mortar 50 buries the front, back, left, and right surfaces of the first to third connecting parts 21 to 23, leaving only the top surface visible, or the top surface is also covered by the mortar 50. After the mortar 50 is laid, the brick assembly is completed by laying the upper bricks 60 in the same manner as in the first or second embodiment.

[0074] In this configuration, the first to third connecting sections 21 to 23 may be placed before the mortar 50 is applied, and the mortar 50 may be applied to fill the first to third connecting sections 21 to 23. Also, although an auxiliary member of the same shape as the first to third connecting sections 21 to 23 is placed on the upper surface of the lower brick 40, the first to third connecting sections 21 to 23 may be further cut at the weakened section 15 and then placed. Furthermore, the main body member 10 may be cut at the central weakened section 15, and the two halves of the main body member 10 may be used as auxiliary members, or one or more pieces cut at other weakened sections 15 may be used. Moreover, the main body member 10 may be placed without being cut at the weakened section 15.

[0075] With the above configuration, the auxiliary members in this usage configuration provide the following effects.

[0076] The weakened portion 15 can be used to cut the bricks and then embedded in the joint, and the base portion 11 and the first to third protruding plate portions 12, 14, and 18 can be used to define the spacing between the upper bricks 60 and the lower bricks 40 so that the width of the joint is constant.

[0077] By utilizing the weakened portion 15, the length of the auxiliary member can be made shorter than the length of the long side of the lower brick 40, so that the auxiliary member can be placed on a single lower brick 40 without protruding.

[0078] When cut at the weakened portion 15, the first to third protruding plate portions 12, 14, and 18 are located at both ends of the base portion 11, and the overall shape becomes U-shaped, which improves stability when placed on a surface.

[0079] <4th usage form> An example of use relating to this configuration will be explained with reference to Figures 17 and 18. In this configuration, the first to third connecting sections 21 to 23 used in the first configuration are cut at the weakened section 15 located approximately in the center in the longitudinal direction to form the spacer 31 shown in Figure 17. Regardless of which of the first to third connecting sections 21 to 23 is cut, one end of the spacer 31 will have one of the first to third protruding plate sections 12, 14, or 18, while the other end will not have any of the first to third protruding plate sections 12, 14, or 18. Note that Figure 17 shows an example in which the third protruding plate section 18 is provided at one end. An example of using the first to third connecting sections 21 to 23 and the second connecting section 22 is shown.

[0080] In the example of use relating to this form of use, the spacer 31 is used after the mortar 50 has been placed on top of the lower bricks 40. The placement of the mortar 50 can be done in the same way as in the first or second form of use, and if it is done in the same way as in the second form, the main body member 10 will remain on the side of the mortar 50 when the spacer 31 is used. Alternatively, as in the third form of use, the first to third connecting parts 21 to 23 may be embedded in the mortar 50.

[0081] The spacer 31 is positioned so that after one upper brick 60 is placed on top of the mortar 50, its back surface abuts against the mortar 50 and one of its upper or lower ends abuts against the short side surface of the upper brick 60. That is, one of the first to third protruding plate portions 12, 14, or 18 of the spacer 31 is placed facing upward. Once the spacer 31 is in place, another upper brick 60 is placed on either side of the spacer 31 so that it abuts against the other of the upper and lower ends of the spacer 31. This ensures that the spacing between the upper bricks 60 is equal to the vertical width of the spacer. After the other upper bricks 60 are placed, mortar 50 is poured between the upper bricks 60. When pouring the mortar 50 between the upper bricks 60, the main body member 10 may be placed in contact with the upper bricks 60 to prevent the mortar 50 from flowing out.

[0082] Alternatively, instead of placing the spacer 31 on the mortar 50, the spacer 31 may be embedded in the mortar 50 before or after the mortar 50 is laid so that the back surface of the spacer 31 abuts against the upper surface of the lower brick 40. In this case as well, since the protruding length of the first to third protruding plate portions 12, 14, and 18 from the back surface of the spacer 31 is larger than the vertical width of the spacer 31, i.e., the height of the mortar 50 that forms the joint, the tips of the first to third protruding plate portions 12, 14, and 18 protrude without being buried in the mortar 50 and can abut against the short side surface of the upper brick 60.

[0083] With the above configuration, the auxiliary members in this usage configuration provide the following effects.

[0084] • When auxiliary members are used to maintain a constant spacing between joints in adjacent building materials, the auxiliary members can be positioned without protruding above the upper surface of the building materials.

[0085] Since the first to third protruding plate sections 12, 14, and 18 are shorter than the height of the upper brick 60, it is possible to prevent the first to third protruding plate sections 12, 14, and 18 from protruding above the upper brick.

[0086] <Variation> In this embodiment, a weakened portion 15 is provided on the main body member 10, and the first to third connecting portions 21 to 23 in the first and third usage modes, and the spacer 31 in the fourth usage mode are formed by cutting the main body member 10 at the weakened portion 15. In this regard, in the first usage mode, the weakened portion 15 may not be provided, and another member having approximately the same length as the first to third connecting portions 21 to 23 may be used. Also, in the third and fourth usage modes, another member having the same height as the main body member 10 may be used.

[0087] In this embodiment, recesses 12a, 14a, and 18a are provided in the first to third protruding plate portions 12, 14, and 18. However, since the recesses 12a, 14a, and 18a are used when the main body member 10 is divided and used as the first to third connecting portions 21 to 23, the recesses 12a, 14a, and 18a do not need to be provided when using members that have the same function as the first to third connecting portions 21 to 23, as in the modified example described above.

[0088] In this embodiment, the length of the main body member 10 is set to be longer than the long sides of the bricks 40 and 60, but the length of the main body member 10 may be shorter than the long sides of the bricks 40 and 60. In this case, as shown in Figure 13, the main body members 10 can be extended by connecting them in the longitudinal direction to make them longer than the long sides of the bricks 40 and 60.

[0089] In each usage configuration, the auxiliary member is used along the long side of the lower brick 40. However, at corners and edges of buildings, it is necessary to form joints on the short side of the bricks as well. In such cases, the auxiliary member may be used along the short side of the lower brick 40. In this case, the main member 10 can be appropriately cut at the weakened portion 15 to form the auxiliary member, and its length should match the length of the short side.

[0090] The shape of each part of the main body component 10 can be changed, added, or deleted as appropriate, as long as it can perform a function equivalent to or similar to that of the intended use.

[0091] In this embodiment, bricks are assembled using mortar, but it can also be used when assembling other rectangular block-shaped building materials, such as concrete blocks or stone, with mortar. In this case, the size of the main body member 10 and the shape of each part can be appropriately changed according to the shape of the building material. Furthermore, the term "rectangular prism" includes materials such as concrete blocks that have cavities or grooves on their sides. In addition, materials with curved corners, such as those with chamfered edges, are also included in the term "rectangular prism." [Explanation of Symbols]
