TECHNICAL FIELD OF THE INVENTION
The present invention relates to a masonry structure and a masonry method of a block in which blocks are stacked up and down.
[0002]
[Prior art]
2. Description of the Related Art In recent years, blocks formed of various lightweight materials such as plastic materials such as fiber-reinforced composite materials have been used instead of conventional concrete blocks for constructing walls of structures. This lightweight block has a smaller weight than a concrete block, is easy to carry and handle, and can be installed very easily, thus helping to improve work efficiency.
[0003]
When a wall or the like is constructed using such blocks, a construction method is adopted in which the blocks are sequentially stacked one by one while being arranged side by side while joining the blocks to each other. An adhesive is used for joining the blocks.
[0004]
[Problems to be solved by the invention]
In the method of assembling the blocks in this manner, the following problems are caused due to the light weight of the blocks. That is, since the adhesive for joining the blocks generally takes a long time to cure, there may be problems such as the block being tilted or the positional shift occurring until the adhesive is cured. In addition, the adhesive expands due to heat generated by the curing reaction of the adhesive, which may cause the block to move or the adhesive to sag. For these reasons, since the thickness of the adhesive filled between the blocks cannot be kept constant, it is difficult to stack the blocks horizontally, and there is a problem that the surfaces of the stacked blocks are not aligned and the appearance is deteriorated. . In addition, there is a problem that the masonry accuracy may be reduced and sufficient strength may not be obtained structurally. For this reason, conventionally, it has been necessary to monitor and reposition the block until the adhesive is sufficiently cured.
[0005]
The present invention has been made in view of such circumstances, and an object of the present invention is to keep a block in a stable state until the adhesive is hardened, and to displace the block and adjust the position of the adhesive. It is an object of the present invention to provide a block masonry structure and a masonry method capable of preventing the sagging of the blocks.
[0006]
[Means for Solving the Problems]
In order to achieve such an object, the block masonry structure according to the present invention is a block masonry structure in which blocks are stacked one on top of the other, forming a space between the upper and lower blocks. A sheet member for temporarily fixing the upper and lower blocks to each other is provided between the two blocks, and the gap is filled with an adhesive (claim 1).
[0007]
Further, the method of masonrying blocks according to the present invention is a method of masonrying blocks in which blocks are stacked up and down, wherein the upper and lower blocks are temporarily fixed to each other while forming an interval between the upper and lower blocks. A sheet member is provided between the two blocks, and the gap is filled with an adhesive.
[0008]
In the masonry structure and the masonry method of these blocks, the sheet member for temporarily fixing the upper and lower blocks to each other while forming an interval is provided between the upper and lower blocks. When the gap is filled with the adhesive, the adhesive can be held at the gap until the adhesive is sufficiently cured. This makes it possible to keep the thickness of the adhesive constant and to prevent the adhesive from dripping. In addition, since the blocks can be temporarily fixed to each other by the sheet member, it is possible to prevent the blocks from being displaced, thereby maintaining the blocks in a stable state until the adhesive is sufficiently cured. it can. Therefore, it is possible to prevent occurrence of a problem that the blocks are overturned or the stacked blocks are not aligned and the appearance is deteriorated. This makes it unnecessary to perform operations such as monitoring and repositioning blocks, and thus can reduce the amount of work. Furthermore, it is possible to construct a high-quality building such as a wall.
[0009]
Further, the sheet member is composed of a pair of bonding sheets having bonding properties with each other, and the pair of bonding sheets are bonded to the lower surface of the upper block and the upper surface of the lower block, respectively. (Claim 2). The sheet member is formed of such a bonding sheet, and is bonded to the lower surface of the upper block and the upper surface of the lower block, respectively, so that only by bonding these pair of bonding sheets, temporary fixing between the blocks can be performed. Easy to do.
[0010]
Preferably, the sheet member is a hook-and-loop fastener (claim 3). Since the sheet member is formed of the hook-and-loop fastener as described above, the blocks can be joined very easily.
[0011]
Preferably, the block is formed of a fiber reinforced plastic material (claim 4). By using a block formed of such a material, it is possible to construct an earthquake-resistant wall or the like that is extremely lightweight and has sufficient strength.
[0012]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment of a masonry structure and a masonry method of a block according to the present invention will be described with reference to the accompanying drawings. 1 to 5 show one embodiment of a masonry structure and a masonry method of a block according to the present invention. Here, a case where a shear-resistant wall is constructed by the masonry structure and the masonry method of the block according to the present invention will be described. FIG. 1 shows an embodiment of the earthquake-resistant wall, FIG. 2 shows the masonry structure of blocks constituting the earthquake-resistant wall in detail, and FIG. 3 shows an embodiment of the block. FIG. 4 and FIG. 5 show one embodiment of a block masonry method.
[0013]
As shown in FIG. 1, the earthquake-resistant wall 2 constructed here is constructed on the floor 6 over the columns 4 of the structure, and a plurality of blocks 10 are arranged side by side in the lateral direction. It is built on top of it one by one. The blocks 10 are joined to each other by an adhesive. Further, the blocks 10 arranged at the left and right ends are fixed to the outer periphery of each of the left and right columns 4, and the block 10 arranged at the lowest stage is fixed to the floor surface 6 by an adhesive.
[0014]
The block 10 used here is a block shaped into a rectangular parallelepiped as shown in FIG. 2, and has a size of, for example, 250 mm in width (W) × 150 mm in height (H) × 200 mm in depth (D). Is formed. The block 10 is made of a plastic material such as FRP (Fiber Reinforced Plastics) and various lightweight materials such as wood and glass, and is a block that is lighter than a conventional concrete block. In the present embodiment, the block 10 includes, for example, a frame-shaped frame portion 12 formed in a rectangular cross section, and a lattice-shaped reinforcing portion 14 provided inside the frame portion 12. In this embodiment, the frame portion 12 and the reinforcing portion 14 are formed by FRP.
[0015]
The frame portion 12 is formed to be wide along the depth direction of the block 10 and is entirely formed in a cylindrical shape. This frame portion 12 is closely bonded to the frame portion 12 of another block 10 that is arranged adjacent to each other. On the other hand, the reinforcing portion 14 is arranged in a lattice shape such that the band plate portion 14a is disposed diagonally across the inside of the frame portion 12 while being slanted. The reinforcing portion 14 supports the frame portion 12 from the inside.
[0016]
FIG. 3A is an enlarged view showing a state of joining between the blocks 10. An adhesive layer 20 having a predetermined thickness is provided on the floor surface 6 with an adhesive in the form of a film layer, and the blocks 10 are installed and stacked on the adhesive layer 20. The block 10 arranged at the lowermost stage is joined to the adhesive layer 20.
[0017]
A space is provided between the blocks 10, and the space is filled with an adhesive 22 so as to fill the space. The adhesive 22 is interposed in the form of a film layer along the interval between the blocks 10 so that the upper and lower surfaces and the side surfaces of the block 10 are bonded to each other in close contact with each other. As a result, the vertical blocks and the horizontal blocks are connected.
[0018]
Further, in the present embodiment, a belt-shaped sheet member 30 is interposed between the upper and lower portions of the block 10. The sheet member 30 is formed of various sheet materials such as a plastic material (including a film material) and a cloth material, and has an adhesive portion to be bonded to each block 10 in order to join the blocks 10 to each other. It has. The sheet member 30 is provided so as to form an interval M between the upper and lower portions of the block 10, and has a thickness of, for example, 1 to 3 mm or the like according to the thickness of the adhesive 22 interposed between the upper and lower portions. Is set as appropriate. As a material for forming the sheet member 30, it is preferable to avoid using a material having poor adhesiveness, for example, a fluorine resin material.
[0019]
In the present embodiment, the sheet member 30 is formed of a hook-and-loop fastener. The hook-and-loop fastener is, for example, a generally well-known "Magic Tape (registered trademark)" or the like, and is constituted by a pair of mutually attachable and detachable joining sheets 30a and 30b. Is provided with, for example, a hook portion (not shown), and the other joining sheet 30b is provided with, for example, a loop portion (not shown). When both joining sheets 30a and 30b are brought into close contact with each other, the hook portion and the loop portion are mutually connected. The two joining sheets 30a and 30b are joined to each other by being hooked. The hook portion and the loop portion are provided on one surface of each of the joining sheets 30a and 30b, and the other surface is provided with an adhesive portion (not shown) for attaching the joining sheets 30a and 30b. As a joining method of the surface fastener, there are various methods such as a sandwiching type and an uneven type other than the above-mentioned loop type.
[0020]
In this embodiment, one joining sheet 30a is attached to the upper surface of the lower block 10, and the other joining sheet 30b is attached to the lower surface of the upper block 10, respectively. FIG. 3B shows a state in which one joining sheet 30 a is attached to the upper surface of the lower block 10. One joining sheet 30a is formed in a band shape, and is disposed at both ends of each block 10 along the depth direction. The other bonding sheet 30b is also attached to the lower surface of the upper block 10, corresponding to the one bonding sheet 30a. The upper and lower portions of the block 10 are joined to each other by the pair of joining sheets 30a and 30b.
[0021]
By providing such a sheet member 30 between the upper and lower portions of the block 10, it is possible to secure a sufficient space M between the blocks 10 for filling the adhesive 22, and to fill the space M with the space M. Until the adhesive 22 hardened sufficiently, the two blocks 10 can be temporarily fixed to each other by the sheet member 30. This can prevent the block 10 from being displaced and the like, and also can hold the adhesive 22 between the blocks 10, thereby preventing the adhesive 22 from sagging. From this, since the block 10 can be held in a stable state, it is possible to solve the problem that the block 10 is overturned and the appearance is poor because the surfaces are not aligned. In addition, this makes it unnecessary to perform operations such as monitoring and repositioning of the block 10, and can reduce the operations. In addition, it is possible to construct a high-quality building such as a wall.
[0022]
Further, even if the upper and lower surfaces of the block 10 have irregularities, the irregularities can be absorbed by the gap M formed by the thickness of the sheet member 30.
[0023]
Next, an example of a masonry procedure of such a block structure will be described. FIG. 4 illustrates an example of the masonry procedure. As shown in FIG. 4A, after a thin adhesive layer 20 is provided on the floor surface 6 by applying an adhesive or the like, the first block 10 is placed on the adhesive layer 20. Install. An adhesive is provided on the side surface of the block 10 in a thin layer by coating or the like. Next, as shown in FIG. 4B, a second block 10 is set so as to be in close contact with the first block via the adhesive.
[0024]
An adhesive is also provided on the side surface of the second block 10 that has been installed, and the blocks 10 are successively installed on the side surface of the block 10 as shown in FIG. After the predetermined number of blocks 10 are arranged in the horizontal direction and the installation of the first-stage block 10 is completed, the installation of the second stage is started. In the second-stage installation work, one joining sheet 30a of the sheet member 30 is attached to the upper surface of each block 10 in the first stage, as shown in FIG. Further, on the upper surface portion, an adhesive 22 is provided on the other portion except for the portion where the one bonding sheet 30a is adhered by coating or the like.
[0025]
On the other hand, as shown in FIG. 4E, the other bonding sheet 30b is attached to the lower surface of the second-stage block 10 stacked on the one bonding sheet 30a. Further, an adhesive 22 is provided on the lower surface portion of the other portion and the side surface portion other than the portion where the other bonding sheet 30b is pasted by applying or the like. When the second-stage block 10 is installed on the first-stage block 10, the joining sheet 30a on the upper surface of the first-stage block 10 is replaced with the joining sheet 30b on the lower surface of the second-stage block 10. To join. Thereby, these two blocks 10 are temporarily fixed. An interval M is provided between the blocks 10, and the adhesive 22 can be held in the interval M until the adhesive 22 is sufficiently cured.
[0026]
In this way, the second-stage blocks 10 are sequentially stacked and placed on the first-stage blocks 10. Further, the one-stage and one-stage blocks 10 are stacked on the second-stage block 10. Finally, the blocks 10 are stacked by a predetermined number of stages to construct the earthquake-resistant wall 2.
[0027]
By stacking the blocks 10 in this way, it is possible to prevent the displacement of the blocks 10 until the adhesive 22 between the blocks 10 is hardened, and to hold the adhesive 22 between the blocks 10. Thus, it is possible to prevent the adhesive 22 from dripping. Thus, the blocks 10 can be joined in a stable state, and problems such as the possibility of overturning and poor appearance due to uneven surfaces can be solved. Therefore, monitoring and repositioning of the block 10 can be unnecessary, and the masonry work of the block 10 can be performed very easily.
[0028]
In the masonry structure or the masonry method according to the present embodiment, blocks having the same shape and the same size are used as the blocks 10. However, the present invention is not limited to such a case. Blocks having different shapes or sizes may be used. Further, as described above, the block according to the present invention may be formed into other shapes other than the rectangular parallelepiped shape, for example, various shapes such as a cubic shape.
[0029]
In addition, the reinforcing portion 14 of the block 10 may be of any other form as long as it supports and reinforces the frame portion 12 from the inside, in addition to the lattice-shaped reinforcing member described above. Further, the block 10 is not limited to the configuration including the frame portion 12 and the reinforcing portion 14, and may be, for example, a hollow or solid rectangular parallelepiped configuration.
[0030]
Further, in the present embodiment, the sheet member 30 is interposed between the upper and lower portions of the block 10. However, the present invention is not limited to such a case. It is only necessary that the sheet member 30 be interposed between them. This is because if the upper and lower spaces of the blocks 10 located at the left and right ends are temporarily fixed, the blocks 10 disposed therebetween are pressed from both the left and right sides even if the upper and lower spaces are not temporarily fixed by the sheet member 30, This is because the displacement can be prevented. That is, as in the above-described embodiment, it is not always necessary to interpose the sheet member 30 between the upper and lower portions of the block 10 disposed therebetween.
[0031]
Further, in the present embodiment, the lowermost block 10 is directly joined to the floor surface 6 without the intermediation of the sheet member 30. However, this is because the floor surface 6 is formed flat as a reference surface and can be sufficiently inserted. This is because, since the adhesive layer 20 is uniform, the thickness of the adhesive layer 20 can be reduced, so that no problem occurs even if the sheet member 30 is not interposed. However, the sheet member 30 for temporary fixing as described above may be appropriately interposed between the lowermost block 10 and the floor surface 6.
[0032]
Further, in the present embodiment, the case where the earthquake-resistant wall is constructed by the blocks has been described. However, the masonry structure and the masonry method of the block according to the present invention are not limited to such a case. As long as it is constructed by assembling blocks, various shaped objects such as monuments may be used in addition to the structural part of the structure.
[0033]
【The invention's effect】
According to the present invention, it is possible to prevent the block from being displaced and the adhesive from sagging until the adhesive is sufficiently cured (claims 1 and 5).
[0034]
Further, the sheet member is composed of a pair of bonding sheets having a bonding property with each other, and the pair of bonding sheets are bonded to the lower surface of the upper block and the upper surface of the lower block, respectively, so that the distance between the blocks is increased. Temporary fixing can be easily performed (claim 2).
[0035]
Further, since the sheet member is a hook-and-loop fastener, the blocks can be very easily joined together (claim 3).
[0036]
Further, since the block is formed of a fiber-reinforced plastic material, it is possible to construct an earthquake-resistant wall or the like which is extremely lightweight and has sufficient strength (claim 4).
