Description

Technical Field

[0001] The present invention relates to a mounting bracket used for an outer wall of a wooden building or the like using a ventilation method, a method for manufacturing a lath net with a mounting bracket, and an outer wall construction method.

Background Art

[0002] In recent wooden buildings or the like, an outer wall having a structure in which a ventilation layer (or a ventilation layer) is provided between a mortar layer formed on the outermost side of the outer wall and a subfloor has been increasingly used. The method of constructing an outer wall provided with a ventilation layer is called a ventilation method (outer wall ventilation method or outer wall construction method).

[0003] In this ventilation method, a resin-made ventilation formwork sheet having a plurality of recesses is arranged on a subfloor made of wood or the like, a lath net is attached from above the ventilation formwork sheet, and further, mortar is applied with a trowel or the like from above the lath net to form an outer wall. The ventilation formwork sheet and the lath net are fixed to the subfloor using a plurality of lath net mounting brackets (see Patent Documents 1 to 4).

Summary of the Invention

Problems to be Solved by the Invention

[0005] Patent documents 1 and 2 disclose a construction method in which a wire mesh mounting bracket is placed in a recess of a ventilated formwork sheet placed on a baseboard, the ventilated formwork sheet and the wire mesh mounting bracket are fixed together with staples, a wire mesh is then placed over the wire mesh mounting bracket, and the hook portion provided on the wire mesh mounting bracket is bent to fix the wire mesh mounting bracket and the wire mesh together. The construction method disclosed in patent documents 1 and 2 requires fixing the wire mesh mounting bracket and the wire mesh on-site, and this on-site work takes a lot of time.

[0006] On the other hand, Patent Document 3 discloses a technology that shortens on-site work processes by pre-fabricating a base lath that integrates the lath mounting bracket and the lath mesh in a factory or the like. However, in the process of creating the integrated base lath disclosed in Patent Document 3, it is necessary to bend the holding part of the lath mounting bracket and fix it to the lath mesh. Therefore, although the on-site work process is shortened, the process of pre-fabricating the components necessary for exterior wall construction (i.e., the integrated base lath) in a factory or the like actually becomes longer.

[0007] On the other hand, Patent Document 4 discloses a wire mesh mounting bracket that presses down on the wires constituting the wire mesh from above, and this wire mesh mounting bracket is characterized by not having a fixing means to fix the wire mesh and the wire mesh mounting bracket to each other. Due to this structure of "not having a fixing means to fix each other," when installing this bracket on site, it was necessary to hold the bracket with one hand and install screws with the other. In order to eliminate this work, a wire mesh with an integrated bracket that fixes the bracket to the wire mesh by welding in advance has been proposed, but this had the problem of increased costs due to the welding process at the factory.

[0008] The problem that this invention aims to solve, taken in view of the above circumstances, is to provide a lath mesh mounting bracket, a lath mesh with a mounting bracket, and an exterior wall construction method that can shorten the overall process, including the process of creating the components necessary for exterior wall construction and the on-site work process. [Means for solving the problem]

[0009] To solve the above problems, the present invention provides a method for manufacturing a lath mesh with mounting brackets for use in an exterior wall ventilation method, in which a ventilated formwork sheet having a flat portion and numerous protrusions formed by pushing out cone-shaped recesses from the flat portion is placed between a lath mesh and a base plate, with the tops of the recesses facing the base plate, and mortar is applied from above the lath mesh to form a ventilation layer between the base plate and the mortar layer, the method comprising an insertion portion, a first extension portion, and a second extension portion The mounting bracket is formed by bending a strip of steel plate so that (a) the insertion portion is shaped to conform to the shape of the recess in the ventilated formwork sheet, (b) the first extension portion extends from one end of the insertion portion and is folded back toward the one end so that the first wire of the grid can be sandwiched at the first folded portion, and (c) the second extension portion extends from the other end of the insertion portion in the opposite direction to the first extension portion and is folded back toward the other end so that the second wire facing the first wire can be sandwiched at the second folded portion. (d) The first extension portion and the second extension portion are formed such that the first extension length from one end of the first extension portion to the first folded portion is longer than the second extension length from the other end of the second extension portion to the second folded portion, and the mounting bracket formed as described above is (a) inserted into the grid of the lath net with the insertion portion so that one end of the insertion portion abuts against the first wire, and (b) the second extension portion is pivoted on the first wire so that the second extension portion does not interfere with the second wire, in the opposite direction to the insertion direction of the insertion portion. (c) With the first extension rotated in the first direction, slide the first extension portion up to the first folded portion while sandwiching the first wire; (d) Rotate the second extension portion in the second direction opposite to the first direction using the first wire as a pivot point, so that the base of the second extension portion comes into contact with the second wire; (e) With the first extension portion and the second extension portion each sandwiching the first wire and the second wire, respectively, slide the mounting bracket so that the insertion portion is located approximately in the center of the grid, thereby fixing the mounting bracket to the lath mesh and manufacturing the lath mesh with the mounting bracket attached. [Effects of the Invention]

[0010] According to the present invention, the mounting bracket, the method for manufacturing a lath mesh with a mounting bracket, and the exterior wall construction method can shorten the overall process, including the process of creating the necessary components for exterior wall construction and the on-site work process. As a result, the overall cost required for exterior wall construction can be reduced. [Brief explanation of the drawing]

Embodiments for Carrying Out the Invention

[0012] Embodiments of the lath attachment fitting according to the present invention will be described with reference to the accompanying drawings.

[0013] (1) Structure of the mortar outer wall Fig. 1 is a view showing an example of the structure of a mortar outer wall 100 using a lath attachment fitting 30 according to an embodiment of the present invention. As shown in Fig. 1, the mortar outer wall 100 has a structure including a bottom plate 10, a ventilation formwork sheet 20, a lath 40, a lath attachment fitting 30, and a mortar layer 50 in order from the inside (the left side in Fig. 1) of the outer wall.

[0014] The bottom plate 10 is, for example, a wooden plywood or a foamed resin plate. When a thick foamed resin plate is used as the bottom plate 10, a heat insulation effect can be obtained.

[0015] As shown in Fig. 1 (also refer to Fig. 2(a)), the ventilation formwork sheet 20 is a sheet having a large number of protrusions 21 formed by extruding a frustum-shaped concave portion 22 from a flat portion 23. This ventilation formwork sheet 20 is formed of, for example, a PET resin or the like.

[0016] The lath 40 is a member used in the mortar outer wall construction method and is a net formed of a metal wire or the like. By providing the lath 40 inside the mortar layer 50, it facilitates the fixing of the mortar layer 50 and makes it difficult for cracks to occur in the mortar layer 50.

[0017] The lath mesh mounting bracket 30 is a fitting used to fix the ventilated formwork sheet 20 and the lath mesh 40 to the baseboard 10. The specific structure and function of the lath mesh mounting bracket 30 will be described later.

[0018] The mortar layer 50 is formed by applying viscous mortar to the lath mesh 40 using a trowel or the like.

[0019] (2) Ventilated formwork sheet and wire mesh Figures 2(a) to 2(c) show examples of the shape of the ventilated formwork sheet 20. Figure 2(a) is a plan view, and Figures 2(b) and 2(c) show the X-X' and Y-Y' cross-sectional views, respectively.

[0020] As mentioned above, the ventilated formwork sheet 20 has numerous projections 21 formed by pushing out a topped cone-shaped recess 22 from the flat surface 23. The height and spacing of the projections 21 are not particularly limited, but the height of the projections 21 is, for example, about 12 to 20 mm. The spacing between each projection 21 is, for example, about 50 to 150 mm. In Figures 2(a) to (c), the arrangement pattern of the projections 21 is shown as a grid (square arrangement), but it is not limited to this, and an arrangement pattern such as a triangular arrangement is also acceptable.

[0021] When the viscous mortar is applied (by applying it with a trowel, etc.), the viscous mortar passes through the gaps in the lath mesh mounting bracket 30 and the lath mesh 40 and fills the recesses 22 of the projections 21. When the mortar filled in the recesses 22 dries, this dried mortar functions as legs that support the mortar layer 50 to the base plate 10. A number of legs corresponding to the number of projections 21 are formed between the mortar layer 50 and the base plate 10, thereby increasing the strength of the mortar layer 50 while maintaining the flatness of the mortar layer 50.

[0022] On the other hand, a space is formed between these legs, and this space becomes a ventilation layer 25 in which air can flow freely in vertical, horizontal, and diagonal directions. This ventilation layer 25 can remove moisture that occurs on the surface and inside of the mortar layer 50 and the baseboard 10.

[0023] The breathable formwork sheet 20 can be made using plastics such as polyethylene, polypropylene, polystyrene, acrylic, polyvinyl chloride, and PET resin. There are no particular limitations on the thickness of the breathable formwork sheet 20, but its mass should be between 200 and 800 g / m². 2 Preferably, the mass is 200 g / m 2 If the mass is less than 200 g / m², the strength will be too low, and the shape of the protrusion 21 will not be maintained when mortar (or concrete) is applied. On the other hand, if the mass is 200 g / m² 2 If the weight exceeds this limit, the ventilated formwork sheet 20 itself becomes too heavy, making transportation and installation inconvenient, and causing it to slide down when fixed to the baseboard 10.

[0024] Figure 2(d) shows an example of the structure of the lath mesh 40. As shown in Figure 2(d), the lath mesh 40 is made up of a grid-like mesh composed of multiple metal wires 41 in the horizontal direction and multiple metal wires 42 in the vertical direction. The multiple metal wires 41 in the horizontal direction and the multiple metal wires 42 in the vertical direction are joined at the points where they intersect with each other, for example by spot welding.

[0025] The mesh shape of the wire mesh 40 is formed to be approximately square, for example. Here, a mesh refers to an individual gap enclosed by the horizontal metal wires 41 and the vertical metal wires 42. When the mesh shape is square, the spacing Dx of the horizontal metal wires 41 and the spacing Dy of the vertical metal wires 42 are equal (Dx=Dy), and the vertical and horizontal dimensions of each mesh are also Dx (=Dy).

[0026] The spacing and dimensions of the mesh are determined based on the spacing and dimensions of the recesses 22 in the ventilated formwork sheet 20. Specifically, when the lath mesh 40 is placed on top of the ventilated formwork sheet 20, the spacing and dimensions of the mesh are determined such that the center of each recess in the ventilated formwork sheet 20 coincides with the center of each mesh in the lath mesh 40, and the diameter of each recess is slightly smaller than the vertical and horizontal dimensions of the mesh in the lath mesh 40.

[0027] Figures 3(a) and 3(b) show the wire mesh 40 placed on top of the ventilated formwork sheet 20, viewed from above. Figure 3(a) is an example where the recesses 22 of the ventilated formwork sheet 20 are arranged in a square pattern. In this case, there is a one-to-one correspondence between each recess 22 of the ventilated formwork sheet 20 and each mesh of the wire mesh 40. On the other hand, Figure 3(b) is an example where the recesses 22 of the ventilated formwork sheet 20 are arranged in a triangular pattern. In this case, each recess 22 of the ventilated formwork sheet 20 is placed every other mesh of the wire mesh 40.

[0028] As shown in Figures 3(a) and (b), regardless of whether the arrangement of the recesses 22 in the ventilated formwork sheet 20 is a square or triangular arrangement, the centers of all the recesses 22 coincide with the centers of the mesh. Therefore, the metal wires 41 and 42 that constitute the lath mesh and the recesses 22 of the ventilated formwork sheet 20 do not interfere with each other. As a result, as will be described later, in the exterior wall construction method according to the present invention, the lath mesh 40 is placed on top of the ventilated formwork sheet 20, and the lath mesh mounting brackets 30 are inserted into the recesses 22 of the ventilated formwork sheet 20 from above the lath mesh 40 through its mesh.

[0029] In contrast, most conventionally used lath meshes are manufactured without considering the arrangement of the recesses 22 in the ventilated formwork sheet 20. As a result, when the ventilated formwork sheet 20 and the lath mesh are superimposed, the center position of the mesh of the lath mesh and the center position of the recesses in the ventilated formwork sheet 20 do not necessarily coincide. Furthermore, there are areas where the metal wires of the lath mesh and the recesses 22 in the ventilated formwork sheet 20 interfere with each other. For this reason, in conventional exterior wall construction methods, as shown in Figures 1 and 2 of Patent Documents 1 and 2, it was necessary to first insert the lath mesh mounting brackets into the recesses of the ventilated formwork sheet 20, and then attach the lath mesh over the mounting brackets.

[0030] (3) Lath mesh mounting brackets Figure 4 is an oblique view showing an example of the external appearance of the wire mesh mounting bracket 30 according to the present invention. Figure 5(b) is a side view of the wire mesh mounting bracket 30 as seen from the direction of arrow A in Figure 4, and Figure 5(a) is an exploded view of the wire mesh mounting bracket 30.

[0031] As shown in Figure 4, the wire mesh mounting bracket 30 has an insertion portion 33, a first extension portion 31, and a second extension portion 32. The insertion portion 33, the first extension portion 31, and the second extension portion 32 are formed, for example, by bending a single strip of steel plate as shown in Figure 5(a).

[0032] The insertion portion 33 is formed in a shape that generally conforms to the shape of the lateral cross-section of the recess 22 of the ventilated formwork sheet 20, so that it can be inserted into the recess 22 of the ventilated formwork sheet 20 through the mesh of the lath net 40 placed on top of the ventilated formwork sheet 20.

[0033] More specifically, the insertion portion 33 includes a bottom portion 330 that faces the bottom of the recess 22 of the ventilated formwork sheet 20 so as to be in contact with it, a first side portion 331 that extends diagonally from one end of the bottom portion 330 toward the first extension portion 31, and a second side portion 332 that extends diagonally from the other end of the bottom portion 330 toward the second extension portion 32.

[0034] As shown in Figure 5(a), the bottom portion 330 has a round hole 333 through which a screw (a predetermined fastening means) is passed to fix the wire mesh mounting bracket 30 to the bottom plate 10 via the ventilated formwork sheet 20. In addition, the first side portion 331 and the second side portion 332 have elongated holes 334 and 335, respectively, for passing mortar through.

[0035] As shown in Figures 4 and 5(b), the first extension portion 31 extends from one end 314 of the insertion portion 33 along the surface of the lath mesh 40, is folded back at the first folded portion 312, and is formed to sandwich the first wire 42 of the first side 421 (see Figure 4) of the grid of the lath mesh 40 into which the insertion portion 33 is inserted.

[0036] More specifically, the first extension portion 31 is comprised of a first extension upper plate 311 extending from one end 314 of the insertion portion 33 along the surface of the lath mesh 40, a first folded portion 312 to which the first extension upper plate 311 is folded back in the opposite direction (towards the insertion portion 33), and a first extension lower plate 313 extending from the first folded portion 312 toward the insertion portion 33. Here, the bending radius of the first folded portion 312 is set such that the distance between the first extension upper plate 311 and the first extension lower plate 313 substantially matches the diameter of the wire 42.

[0037] On the other hand, as shown in Figures 4 and 5(b), the second extension portion 32 extends from the other end 324 of the insertion portion 33 along the surface of the lath mesh 40, is folded back at the second folded portion 322, and is formed to sandwich the second wire 42 of the second side 422 (see Figure 4) that is opposite to the first side 421 of the grid of the lath mesh 40.

[0038] More specifically, the second extension portion 32 is comprised of a second extension upper plate 321 extending along the surface of the lath mesh 40 from the other end 324 of the insertion portion 33, a second folded portion 322 to which the second extension upper plate 321 is folded back in the opposite direction (towards the insertion portion 33), and a second extension lower plate 323 extending from the second folded portion 322 toward the insertion portion 33. Here, similar to the first extension portion 31, the bending radius of the second folded portion 322 is set so that the distance between the second extension upper plate 321 and the second extension lower plate 323 is approximately equal to the diameter of the wire 42.

[0039] As described above, the lath mesh mounting bracket 30 of the embodiment can be formed by bending a single strip of steel plate. Specifically, the lath mesh mounting bracket 30 of the embodiment shown in Figures 4 and 5(b) can be formed by bending a single strip of steel plate by press working. In addition, the round hole 333 and the elongated holes 334 and 335 of the insertion portion 33 can also be formed by drilling holes by press working. Thus, since the lath mesh mounting bracket 30 of the embodiment can be formed by press working alone from a strip of steel plate, it can be produced in large quantities and at low cost with minimal processing time.

[0040] In this embodiment, in the wire mesh mounting bracket 30, it is preferable that the first extension portion 31 and the second extension portion 32 are formed such that the first extension length D1 from one end 314 of the insertion portion 33 to the first folded portion 312 is longer than the second extension length D2 from the other end 324 of the second extension portion 32 to the second folded portion 322, in order to facilitate the work of fixing the wire mesh mounting bracket 30 to the wire mesh 40.

[0041] More specifically, it is preferable that the first extension portion 31 and the second extension portion 32 are formed such that the first extension length D1 is approximately twice the second extension length D2 (D1 ≈ 2 * D2). However, the lengths of the first extension portion 31 and the second extension portion 32 may be the same.

[0042] Furthermore, when the opening spacing of the widest part of the insertion portion 33 is D3, it is preferable to form it such that the sum of half of the first extension length D1, the second extension length D2, and the opening spacing D3 approximately matches the spacing Dx (or Dy) of the grid of the wire mesh 40.

[0043] In other words, it is preferable to assume that Dx ≈ D1 / 2 + D2 + D3 ≈ 2*D2 + D3.

[0044] Figures 6 and 7 illustrate a method for manufacturing a wire mesh with mounting brackets, in which mounting brackets 30 are fixed to the wire mesh 40 to produce a wire mesh with mounting brackets. Due to the effects of the length relationship between the first extension length D1, the second extension length D2, and the opening spacing D3 described above, the work of fixing the wire mesh mounting brackets 30 to the wire mesh 40 becomes simple and easy.

[0045] First, the manufacturing method of the mounting bracket 30 described above is summarized below.

[0046] A mounting bracket 30, comprising an insertion portion 33, a first extension portion 31, and a second extension portion 32, is manufactured by bending a strip of steel plate in the following steps.

[0047] Step (a) The insertion portion 33 is formed to conform to the shape of the recess 22 of the ventilated formwork sheet 20.

[0048] Step (b) The first extension portion 31 is formed to extend from one end 314 of the insertion portion 33 and to be folded back toward the one end 314 so that the first folded portion 312 can sandwich the first wire 42 of the grid.

[0049] Step (c) The second extension portion 32 is formed to extend from the other end 324 of the insertion portion 33 in the opposite direction to the first extension portion 31, and to be folded back toward the other end 324 so that the second wire facing the first wire can be sandwiched by the second folded portion 322.

[0050] Step (d) The first extension portion 31 and the second extension portion 32 are formed such that the first extension length from one end 314 of the first extension portion 31 to the first folded portion 312 is longer than the second extension length from the other end 324 of the second extension portion 32 to the second folded portion 322. As mentioned above, the lengths of the first extension portion 31 and the second extension portion 32 may be the same.

[0051] Next, the mounting bracket 30 manufactured as described above is fixed to the wire mesh 40 in the following steps to manufacture a wire mesh with mounting brackets. Step (a) Insert the insertion part 33 into the grid of the lath mesh 40 so that one end 314 of the insertion part 33 abuts against the first wire 42 on the left side. Step (a) With the second extension portion 32 rotating in the first direction (upward in Figures 6 and 7), which is opposite to the insertion direction of the insertion portion 33, using the left first wire 42 as a pivot point so that the second extension portion 32 does not interfere with the right second wire 42, the first extension portion 31 is slid up to the first folded portion 312 while sandwiching the left first wire 42. Step (c) Using the left-side first wire 42 as a pivot point, the second extension 32 is rotated in a second direction opposite to the first direction (downward in Figures 6 and 7) so that the base of the second extension 32 comes into contact with the right-side second wire 42. Step (E) With the first extension portion 31 and the second extension portion 32 sandwiching the first wire 42 on the left and the second wire 42 on the right, respectively, the mounting bracket 30 is fixed to the wire mesh 40 by sliding the mounting bracket 30 so that the insertion portion 33 is positioned approximately in the center of the grid.

[0052] According to the steps described above, the process of fixing the mounting bracket 30 to the lath mesh 40 becomes simple and easy, and the overall process, including the creation of materials necessary for exterior wall construction and the on-site work process, can be shortened.

[0053] Figure 8(a) shows a first modified example of the mounting bracket 30, and Figure 8(b) shows a second modified example of the mounting bracket 30.

[0054] In the first modified example shown in Figure 8(a), the distance between the entrances of the first extension 31 and the second extension 32 is made slightly narrower than the diameter of the wire 42, while the distance between the backs of the first extension 31 and the second extension 32 (the first folded portion 312 and the second folded portion 322) is made slightly wider than the diameter of the wire 42. For example, when the diameter of the wire is 1.4 mm, the distance between the entrances of the first extension 31 and the second extension 32 is 1.2 mm, and the distance between the backs (the first and second folded portions) is 1.5 mm. By forming the mounting bracket 30 in this first modified example, the wire's cross-section is round, so it fits into the gap at the entrance, and once it goes further in, it becomes difficult to detach.

[0055] In the second modified example shown in Figure 8(b), projections 314 and 324 are provided at the entrances of the first extension 31 and the second extension 32, respectively. For example, when the diameter of the wire is 1.4 mm, the distance between the upper and lower sides of the folds of the first extension 31 and the second extension 32 is set to 1.5 mm, and the height of the entrance projections 314 and 324 is set to 0.2 mm. By forming the mounting bracket 30 in this second modified example, the wire 42 that has entered the back of the projection is blocked by the entrance projections 314 and 324, making it difficult for it to come loose.

[0056] It should be noted that the present invention is not limited to the embodiments described above, and the components can be modified and implemented in practice without departing from the spirit of the invention. Furthermore, various inventions can be formed by appropriately combining the multiple components disclosed in the above embodiments. For example, some components may be deleted from all the components shown in the embodiments. Moreover, components from different embodiments may be appropriately combined. [Explanation of Symbols]

(c) Rotate the second extension in a second direction opposite to the first direction using the first wire as a pivot point, so that the base of the second extension comes into contact with the second wire. (e) With the first extension and the second extension respectively sandwiching the first wire and the second wire, the mounting bracket is fixed to the lath mesh by sliding the mounting bracket so that the insertion portion is located approximately in the center of the grid, thereby manufacturing the lath mesh with the mounting bracket attached. A method for manufacturing wire mesh with mounting brackets.

2. The first extension and the second extension are, The first extension length from one end of the first extension to the first folded portion is formed to be longer than the second extension length from the other end of the second extension to the second folded portion. A method for manufacturing a wire mesh with mounting hardware as described in claim 1.

3. The first extension and the second extension are formed such that the length of the first extension is approximately twice the length of the second extension. A method for manufacturing a wire mesh with mounting hardware as described in claim 2.
