Description

[Technical field]

[0001] The present invention relates to a wire mesh for construction, and more particularly to a wire mesh for construction that is embedded in concrete that constitutes a concrete slab or the like. [Background technology]

[0002] As an architectural wire mesh to be embedded in concrete constituting a concrete slab or the like, for example, an architectural wire mesh as described in the following Patent Document 1 is known. The architectural wire mesh described in Patent Document 1 is composed of a plurality of iron wires (a first group of iron wires) each extending in parallel and a plurality of iron wires (a second group of iron wires) each extending in a direction perpendicular to the direction in which each of the iron wires in the first group of iron wires extends, and is formed into a square or rectangular shape in plan view. In the plan view direction, each of the iron wires in the first group of iron wires is welded to one side of each of the iron wires in the second group of iron wires.

[0003] [Patent Document 1] JP 2009-185532 A Summary of the Invention [Problem to be solved by the invention]

[0004] Generally, when constructing a concrete slab, in order to prevent cracks in the concrete, a construction wire mesh as described in the above Patent Document 1 is laid on a framework constructed of beams, and concrete is then poured on the framework. The construction wire mesh is formed to a size that can be accommodated in the bed of a truck (i.e., a size smaller than the framework) so that it can be transported to the construction site, and therefore, at the construction site, multiple construction wire meshes are laid side by side on the framework. However, if multiple construction wire meshes are laid without overlapping each other, the construction wire meshes may shift when pouring concrete, resulting in the occurrence of places in the poured concrete where the construction wire meshes are not present, and in particular in those places, cracks may occur in the concrete. Therefore, in order to prevent this, the construction wire meshes are laid by overlapping the edges of adjacent construction wire meshes.

[0005] Incidentally, in concrete slabs and the like, it is preferable to ensure a certain degree of cover thickness in order to prevent oxidation of metals in the concrete, such as architectural wire mesh. However, in the area where the edges of the architectural wire mesh overlap, the total thickness of the overlapped architectural wire mesh becomes thicker than the other areas of the architectural wire mesh laid on the framework. Therefore, if it is desired to make the cover thickness of the overlapping areas of the architectural wire mesh the same as the cover thickness of the other areas, it is necessary to take measures such as pouring concrete while pressing down the overlapping areas of the architectural wire mesh, which can be time-consuming and difficult to install.

[0006] The present invention has been made in consideration of the above points, and one of its objectives is to provide a building wire mesh that can reduce the thickness of the overlapping parts of the building wire mesh. [Means for solving the problem]

[0017] Hereinafter, embodiments for carrying out the architectural wire mesh according to the present invention will be illustrated with reference to the accompanying drawings. The embodiments illustrated below are intended to facilitate understanding of the present invention, and are not intended to limit the present invention. The present invention can be modified or improved from the following embodiments without departing from the spirit of the present invention. In addition, in the above-mentioned attached drawings, the dimensions of each component may be exaggerated or reduced, or hatching may be omitted, in order to facilitate understanding.

[0018] First, before describing the architectural wire mesh of this embodiment, a comparative example of the architectural wire mesh will be described.

[0019] FIG. 1 is a plan view showing a part of the comparative example of the installed architectural wire mesh. In FIG. 1, four architectural wire meshes 910, 920, 930, 940 of the comparative example are shown. As shown in FIG. 1, each of the architectural wire meshes 910, 920, 930, 940 has a roughly similar configuration. Specifically, each of the architectural wire meshes 910, 920, 930, 940 is a square or a rectangle in a plan view. In addition, each of the architectural wire meshes 910, 920, 930, 940 is formed in a two-layer lattice shape by welding a plurality of reinforcing bars 911, 921, 931, 941 extending in the X direction as the first layer to a plurality of reinforcing bars 912, 922, 923, 934 extending in the Y direction perpendicular to the X direction as the second layer.

[0020] In the area shown in Fig. 1, the four architectural wire meshes 910, 920, 930, and 940 are laid out with their edges overlapping each other. Therefore, in the example of Fig. 1, the edges of the architectural wire meshes 910, 920, 930, and 940 overlap each other in the approximate center of the figure, forming a four-ply architectural wire mesh.

[0021] Fig. 2 is a part of the cross section (cross section in the Z direction perpendicular to the X and Y directions) on line AA in Fig. 1, and shows the above-mentioned four-ply portion in a schematic manner. As shown in Fig. 2, architectural wire meshes 910, 920, 930, 940 are embedded in concrete Ct. Furthermore, architectural wire meshes 920, 940 are stacked in an inverted state with respect to architectural wire meshes 910, 930 in the Z direction (vertical direction). That is, in architectural wire meshes 910, 930, multiple reinforcing bars 912, 932 are located below multiple reinforcing bars 911, 931, whereas in architectural wire meshes 920, 940, multiple reinforcing bars 922, 942 are located above multiple reinforcing bars 921, 941. As a result, the four-ply portion where all of the architectural wire mesh 910, 920, 930, 940 are overlapped forms a six-layer structure consisting of a first layer made up of multiple reinforcing bars 911, a second layer made up of multiple reinforcing bars 912, 922, a third layer made up of multiple reinforcing bars 921, a fourth layer made up of multiple reinforcing bars 931, a fifth layer made up of multiple reinforcing bars 932, 942, and a sixth layer made up of multiple reinforcing bars 941.

[0022] The four architectural wire meshes 910, 920, 930, 940 may be stacked without inverting the architectural wire meshes 920, 940. In this case, the four-ply portion where all of the architectural wire meshes 910, 920, 930, 940 are stacked will have an eight-layer structure. In this way, when the architectural wire mesh of the comparative example is used, a portion is formed inside the concrete Ct where four architectural wire meshes are stacked and six or more layers of reinforcing bars are stacked.

[0023] Next, a construction wire mesh according to an embodiment of the present invention will be described.

[0024] FIG. 3 is a plan view showing an example of an architectural wire mesh according to an embodiment of the present invention, and FIG. 4 is a perspective view showing a part of the architectural wire mesh shown in FIG. 3 rotated 90°. As shown in FIGS. 3 and 4, the architectural wire mesh 1 according to one embodiment of the present invention has a configuration in which a single metal plate is molded into a mesh shape. For example, the architectural wire mesh 1 may be formed into a mesh shape by punching a single metal plate, or may be a mesh-shaped metal plate formed using a 3D metal printer. That is, the architectural wire mesh 1 has a single-layer structure. This architectural wire mesh 1 has a size that allows it to be loaded onto a specified transport vehicle so that it can be transported to a construction site.

[0025] The architectural wire mesh 1 includes a plurality of linear portions 11, 12, 13 including linear portions extending linearly in different directions, and a plurality of intersections Cr1 where the linear portions 11, 12, 13 intersect. The linear portions 11, 12, 13 include a plurality of first linear portions 11 (hereinafter also referred to as the "first linear portion group 11G") extending linearly in a first direction, a plurality of second linear portions 12 (hereinafter also referred to as the "second linear portion group 12G") extending linearly in a second direction, and a plurality of third linear portions 13 (hereinafter also referred to as the "third linear portion group 13G") extending linearly in a third direction. The first direction, the second direction, and the third direction are directions that intersect with each other at an obtuse angle of 120° (acute angle of 60°). That is, the first straight line portion group 11G and the second straight line portion group 12G, the first straight line portion group 11G and the third straight line portion group 13G, and the second straight line portion group 12G and the third straight line portion group 13G each intersect at an obtuse angle of 120° (an acute angle of 60°).

[0026] The first linear portion group 11G, the second linear portion group 12G, and the third linear portion group 13G are on the same plane. Therefore, the first linear portion group 11G, the second linear portion group 12G, and the third linear portion group 13G intersect on the same plane to form the above-mentioned multiple intersections Cr1 on the same plane. In each of the multiple intersections Cr1, one first linear portion 11 of the first linear portion group 11G, one second linear portion 12 of the second linear portion group 12G, and one third linear portion 13 of the third linear portion group 13G intersect with each other at an obtuse angle of 120° (acute angle of 60°).

[0027] The width and thickness of each of the linear portions 11, 12, and 13 are not particularly limited, but may be, for example, about 6 mm in width and about 6 mm in thickness. As shown in Fig. 4, in this embodiment, each of the linear portions 11, 12, and 13 is formed to have a substantially rectangular cross section, but is not limited thereto, and may be formed to have a cross section such as a circle without corners.

[0028] When viewed in a plan view, i.e., when viewed from a direction perpendicular to the same plane including the linear portions 11, 12, 13 and the intersections Cr1, the architectural wire mesh 1 is polygonal, and in this embodiment, is hexagonal, more specifically, is a hexagon with the first direction as the longitudinal direction. Therefore, the architectural wire mesh 1 has a hexagonal outer edge 1E with the first direction as the longitudinal direction. The outer edge 1E includes two first linear portions 11, 11, two second linear portions 12, 12, and two third linear portions 13, 13 (hereinafter, the linear portions constituting the outer edge 1E may be referred to as the "first linear portion 11E", the "second linear portion 12E", and the "third linear portion 13E"). In this embodiment, each of the two first linear portions 11E, 11E of the outer edge 1E is longer than each of the other linear portions 12E, 13E of the outer edge 1E. However, each of the two first linear portions 11E, 11E of the outer edge 1E may be the same as or shorter than the other linear portions 12E, 13E of the outer edge 1E. In addition, the outer edge 1E includes six intersections Cr1 among the multiple intersections Cr1, and each of these six intersections Cr1 forms a corner of a hexagon. Hereinafter, each of the six intersections Cr1 forming the corners of the outer edge 1E will be referred to as a corner Cn1. In this embodiment, each of the six corners Cn1 is 120°, but it is sufficient that at least one of the angles Cn1 is 120°.

[0029] As described above, in this embodiment, the first straight portion group 11G and the second straight portion group 12G, the first straight portion group 11G and the third straight portion group 13G, and the second straight portion group 12G and the third straight portion group 13G intersect at angles of 120°, respectively.With this configuration, multiple triangular (in this embodiment, equilateral triangle) gaps G are formed inside the outer edge 1E of the architectural wire mesh 1, surrounded by the first straight portion group 11G, the second straight portion group 12G, and the third straight portion group 13G.

[0030] As described above, the architectural wire mesh 1 has a number of straight portions 11, 12, 13 including straight portions extending in different directions on the same plane, and the straight portions among the multiple straight portions 11, 12, 13 extending in different directions on the same plane intersect on the same plane to form a number of intersection points Cr1, and the outer edge 1E of the architectural wire mesh 1 is a polygon including some of the straight portions among the multiple straight portions 11, 12, 13 and some of the intersection points Cr1, and at least one of the corners Cn1 of the outer edge 1E forms an angle of 120°.

[0031] FIG. 5 is a plan view showing another embodiment of the architectural wire mesh according to the present invention. The architectural wire mesh 2 shown in FIG. 5 has the same structure as the architectural wire mesh 1 except for the difference in planar shape. That is, the architectural wire mesh 2 has a single-layer structure. The architectural wire mesh 2 has a plurality of linear portions 21, 22, 23 including linear portions extending linearly in different directions, and a plurality of intersections Cr2 where the linear portions 21, 22, 23 intersect. The linear portions 21, 22, 23 include a plurality of first linear portions 21 ("first linear portion group 21G") extending linearly in the first direction, a plurality of second linear portions 22 ("second linear portion group 22G") extending linearly in the second direction, and a plurality of third linear portions 23 ("third linear portion group 23G") extending linearly in the third direction. The first straight line portion group 21G and the second straight line portion group 22G, the first straight line portion group 21G and the third straight line portion group 23G, and the second straight line portion group 22G and the third straight line portion group 23G each intersect at an obtuse angle of 120° (an acute angle of 60°).

[0032] The first linear portion group 21G, the second linear portion group 22G, and the third linear portion group 23G are on the same plane. The first linear portion group 21G, the second linear portion group 22G, and the third linear portion group 23G intersect on the same plane to form the above-mentioned multiple intersections Cr2 on the same plane. In each of the multiple intersections Cr2, one first linear portion 21 of the first linear portion group 21G, one second linear portion 22 of the second linear portion group 22G, and one third linear portion 23 of the third linear portion group 23G intersect with each other at an obtuse angle of 120° (acute angle of 60°).

[0033] The architectural wire mesh 2 is a polygon when viewed from above, and in this embodiment, it is a trapezoid, more specifically, an isosceles trapezoid with the first direction as the longitudinal direction. Therefore, the architectural wire mesh 2 has an outer edge 2E of an isosceles trapezoid with the first direction as the longitudinal direction. The outer edge 2E includes two first linear portions 21, 21, one second linear portion 22, and one third linear portion 23 (hereinafter, the linear portions forming the outer edge 2E may be referred to as the "first linear portion 21E", the "second linear portion 22E", and the "third linear portion 23E"). In addition, the outer edge 2E includes four intersections Cr2 out of the multiple intersections Cr2, and each of these four intersections Cr2 forms a corner of the isosceles trapezoid. Hereinafter, each of the four intersections Cr2 that are corners of the outer edge 2E will be referred to as a corner Cn2. In this embodiment, of the outer edge 2E of the isosceles trapezoid, each of the two angles Cn2 formed by the shorter base sides is 120°, and each of the two angles Cn2 formed by the longer base sides is 60°.

[0034] Inside the outer edge 2E of the architectural wire mesh 2, multiple triangular (in this embodiment, equilateral triangle) gaps G are formed surrounded by the first straight portion group 21G, the second straight portion group 22G, and the third straight portion group 23G.

[0035] As described above, the architectural wire mesh 2 has a plurality of straight portions 21, 22, 23 including straight portions extending in different directions on the same plane, and the straight portions among the plurality of straight portions 21, 22, 23 extending in different directions on the same plane intersect on the same plane to form a plurality of intersection points Cr2, and the outer edge 2E of the architectural wire mesh 2 is a polygon including some of the straight portions among the plurality of straight portions 21, 22, 23 and some of the intersection points Cr2 among the plurality of intersection points Cr2, and at least one of the corners Cn2 of the outer edge 2E forms an angle of 120°.

[0036] The above-mentioned architectural wire mesh 1, 2 can be buried in concrete to prevent cracks in the concrete of the slab. FIG. 6 is a plan view showing a schematic and exemplary part of a concrete slab on which the architectural wire mesh 1, 2 is laid. FIG. 7 is a diagram showing a schematic cross section along line BB in FIG. 6. In the example of FIG. 6 and FIG. 7, a framework consisting of a column (steel frame) 100, a first beam (steel frame) 101 extending from the column 100 in a first direction, and a second beam (steel frame) 102 extending from the column 100 in a fourth direction perpendicular to the first direction is constructed at a construction site, and multiple deck plates De are spanned across this framework. Then, with multiple architectural wire meshes 1, 2 laid on these deck plates De, concrete Ct is poured on the deck plate De. As a result, the architectural wire meshes 1, 2 are buried in the concrete Ct. In FIG. 6, the outer edge of the concrete Ct is shown by a dashed line to clearly show the architectural wire meshes 1, 2.

[0037] As shown in Fig. 6, multiple architectural wire meshes 1, 2 are laid on a deck plate De via spacers (not shown) so that the edges of the architectural wire meshes 1, 2 overlap. This prevents adjacent architectural wire meshes from shifting when pouring concrete Ct, resulting in areas where no architectural wire mesh is present, and prevents cracks from occurring in the concrete Ct at those areas.

[0038] Here, as described above, the outer edges 1E, 2E of the architectural wire meshes 1, 2 have angles Cn1, Cn2 that form an angle of 120°. Therefore, by laying the architectural wire meshes 1, 2 so that the angles Cn1, Cn2 that form an angle of 120° overlap, the architectural wire meshes 1, 2 can be laid on the deck plate De without any gaps in a plan view. Specifically, in the example of FIG. 6, multiple architectural wire meshes 1 are laid on most of the deck plate De of the framework so that their edges overlap. Therefore, there are places where an isosceles trapezoidal gap occurs between the architectural wire meshes 1, 1. Therefore, in the example of FIG. 6, the architectural wire mesh 2 is laid in this isosceles trapezoidal gap so that the edge of the architectural wire mesh 1 and the edge of the architectural wire mesh 2 overlap. As a result, the architectural wire meshes 1, 2 are laid on the deck plate De without any gaps when viewed in a plan view, resulting in areas where the three architectural wire meshes overlap (for example, the area indicated by line BB in Figure 6).

[0039] Since the architectural wire meshes 1, 2 include angles Cn1, Cn2 that form an angle of 120° at the outer edges 1E, 2E, by overlapping the 120° corners as shown in Figures 6 and 7, the number of overlapping architectural wire meshes in the area where the architectural wire meshes overlap most (i.e., the area of ​​line BB in Figure 6) can be reduced to three.

[0040] FIG. 7 shows a cross section of the overlapping edge of three adjacent architectural wire meshes 1A, 1B, 1C among multiple architectural wire meshes 1. The fifth direction shown in FIG. 7 is the vertical direction, which is perpendicular to the first, second, third, and fourth directions. As described above, the architectural wire meshes 1 and 2 have a single-layer structure in which multiple linear portions and multiple intersections are included in the same plane, so that the number of layers of the architectural wire mesh in the maximum overlapping portion (three-layer overlapping portion) is three layers, as shown in FIG. 7. In this way, according to the architectural wire meshes 1 and 2, it is possible to reduce the thickness of the overlapping portion of the architectural wire meshes, and as a result, even in the maximum overlapping portion of the architectural wire meshes, the covering thickness Tu from the uppermost architectural wire mesh 1A to the upper surface Ctu of the concrete Ct (the surface opposite to the deck plate De side in the fifth direction) can be relatively easily secured. For example, according to the architectural wire mesh 1, 2 of this embodiment, a thicker cover thickness Tu can be ensured compared to the cover thickness Tu (the thickness from the first layer of reinforcing bars 911 to the top surface Ctu of the concrete Ct) in the comparative example of Figure 2, in which the maximum number of overlaps of the architectural wire mesh is four, i.e., six or more layers.

[0041] Furthermore, in architectural wire mesh 1, each of the six corners Cn1 forms an angle of 120°, so that no matter which corner Cn1 is overlapped with a corner Cn1 of another architectural wire mesh 1, the number of overlaps of the architectural wire mesh in the part where the architectural wire mesh overlaps maximum can be made three, and the number of layers of the architectural wire mesh in the part where the architectural wire mesh overlaps maximum can be made three.

[0042] It is also possible to form a single-layer architectural wire mesh so that the outer edge is rectangular or square. However, in this case, if the architectural wire mesh is laid on the deck plate so that the edges overlap, the number of overlaps of the architectural wire mesh at the part where the architectural wire mesh overlaps the most will be four, and the number of layers of architectural wire mesh in that part will be four. Therefore, even compared to this case, with architectural wire mesh 1 and 2, it is possible to reduce the thickness of the overlapping parts of the architectural wire mesh.

[0043] As described above, the architectural wire mesh 1, 2 is composed of the first straight line portion group 11G extending in the first direction, the second straight line portion group 12G extending in the second direction, and the third straight line portion group 13G extending in the third direction, forming a mesh structure with triangular voids G. With this configuration, the architectural wire mesh 1, 2 can support forces in three directions, effectively reinforcing the concrete Ct.

[0044] Although the present invention has been described above by taking the above embodiment as an example, the present invention is not limited to this.

[0045] For example, architectural wire mesh 1 may be modified to form architectural wire mesh 1A with an outer edge 1Ea of a regular hexagon in plan view, as shown in Fig. 8. Architectural wire mesh 1A can be made shorter in length in the first direction than architectural wire mesh 1, making it more compact. On the other hand, architectural wire mesh 1 allows the number of architectural wire mesh sheets to be installed to be reduced.

[0046] In addition, the architectural wire mesh 2 may be modified to form an architectural wire mesh 2A having an outer edge 2Ea that is trapezoidal in plan view, as shown in FIG. 9. The outer edge 2Ea of the architectural wire mesh 2A includes two first linear portions 21E extending in a first direction, one third linear portion 23E extending in a third direction, and one fourth linear portion 24E extending in a fourth direction perpendicular to the first direction. The outer edge 2Ea may include one second linear portion 22E instead of one third linear portion 23E. The outer edge 2Ea has one 120° angle Cn2, one 60° angle Cn2, and two 90° angles Cn2. Therefore, for example, in Figure 6, by spanning an architectural wire mesh 2A having an outer edge 2Ea that includes a fourth straight portion 24E extending in the fourth direction across a second beam 102, the portion (edge) of the architectural wire mesh 2A that spans across the second beam 102 can be made parallel to the fourth direction.

[0047] Also, architectural wire mesh 1 may be modified to form architectural wire mesh 1B as shown in Fig. 10. The first straight portion group 11G of architectural wire mesh 1B consists of only two first straight portions 11E, 11E that form the outer edge 1E. Therefore, in architectural wire mesh 1B, in addition to the equilateral triangular gap G formed along the first straight portion 11E, multiple parallelogram-shaped gaps G' are formed that are surrounded by the second straight portion group 12G and the third straight portion group 13G.

[0048] In addition, those skilled in the art can appropriately modify the method for constructing protective work of the present invention in accordance with conventionally known knowledge. As long as the configuration of the present invention is still provided even after such modifications, it is of course included in the scope of the present invention. [Explanation of symbols]
