The conventional method for fixing the bird net, such as fixing the bird net to the mounting part with a flat plate, washer, and screw, or fixing the flat plate for fixing and the bird net by welding in the previous process, is troublesome. Is. Since these are performed manually, it has been a heavy burden in the assembly work of the sash frame.

In addition, in the case of fixing by welding, there is a limit to the applicable birdproof net. For example, a crimp wire mesh coated with a synthetic resin, a pre-painted crimp wire mesh or a welded wire mesh cannot be welded.

An object of the present invention is to provide a construction wire mesh holding member to which a construction wire mesh such as a birdproof net can be easily attached.

In order to solve the above-described object, the wire mesh holding member for building of the present invention includes a first plate-like portion extending in a band shape, and a second plate-like portion facing the first plate-like portion with a predetermined gap therebetween. And a groove formed between the first plate-like portion and the second plate-like portion, and the first plate-like portion and the second plate-like portion have a plurality of protrusions protruding toward the groove portion in the length direction. It is provided along. Furthermore, it is preferable that a bolt through hole is provided. It is also possible to provide a drain hole at the bottom of the groove so that water does not accumulate in the groove.

The building wire mesh member of the present invention has the above-described building wire mesh holding member and a polygonal (for example, rectangular, trapezoidal, triangular, etc.) crimp wire mesh, and the building wire mesh holding member on at least two opposing sides. Is attached.

The building wire mesh holding member of the present invention can easily hold the wire mesh simply by inserting the wire mesh into the wire mesh insertion groove formed between the first plate-like portion and the second plate-like portion. Thus, the building wire mesh member to which the building wire mesh holding member is attached can be easily attached to a sash frame or a building. There is no restriction by the material of the construction wire mesh, and it can be applied to a wire mesh that cannot be welded.

An embodiment for carrying out the present invention will be described with reference to the drawings. FIG. 1 is a front view showing a construction wire mesh holding member, FIG. 2 is a side view thereof, and FIG. 3 is a bottom view thereof.

The construction wire mesh holding member 1 is a member having a shape extending linearly as a whole. Between the 1st plate-shaped part 2 and the 2nd plate-shaped part 3 which the 1st plate-shaped part 2 extended in the strip | belt shape, the 2nd plate-shaped part 3 which opposes the 1st plate-shaped part 2 on both sides of a predetermined | prescribed clearance gap It has the groove part 4 formed in this. The first plate-like portion 2 and the second plate-like portion 3 are connected at one side (the upper side in FIGS. 1 and 2), and the other side is separated. Therefore, it has a substantially U-shaped cross section as shown in FIG.

The first plate-like portion 2 and the second plate-like portion 3 are provided with a plurality of protrusions 5 protruding toward the groove portion 4 along the length direction of the construction wire mesh holding member 1. In this example, the height from the groove bottom is constant, and the protrusions 5 are arranged in one row, but may be two or more rows. The interval between the protrusions is constant. Further, the protrusions of the first plate-like portion 2 and the second plate-like portion 3 are alternately arranged, and are staggered when viewed from the opening.

Further, the construction wire mesh holding member 1 of this example is provided with bolt through holes 6. The bolt through hole 6 penetrates the first plate-like portion 2 and the second plate-like portion 3 and has a size that allows a fixing bolt to pass therethrough. Further, a drain hole 8 is provided at the bottom of the groove 4 so that water does not accumulate in the groove 4.

There is no limitation in particular in the dimension of the construction metal-mesh holding member 1, and it can select suitably based on the shape of the construction metal-mesh which should be hold | maintained. For example, in the case of a crimped wire mesh having a wire diameter of 1.6 mm and an opening of 15 mm, the height H is about 10 to 40 mm, the width W of the groove is about 2 to 3 mm, and the thickness is about 0.6 to 1.2 mm. Can be formed. The length L may be set based on the length of the side of the construction wire mesh to be attached. Moreover, the height (protrusion amount) of the protrusion is about 1 to 2 mm, and is formed at a position of 10 to 20 mm from the groove bottom at intervals of 50 to 150 mm. As materials, zinc-aluminum alloy-plated steel plates, zinc-aluminum-magnesium alloy-plated steel plates, galvanized steel plates, steel plates coated with these plated steel plates, or stainless steel plates can be used.

Below, the example of the manufacturing method of the metal-mesh holding member 1 for construction is demonstrated. First, a band-shaped metal plate having a width slightly larger than twice the height L of the metal wire holding member 1 for construction is prepared, and protrusions are formed on the metal plate. The metal plate thus formed with the protrusions is bent along the center line in the width direction so that the protrusions face inward.

For example, a protrusion can be formed on a strip-shaped metal plate having the length of the wire mesh holding member 1 for construction by a press, and further bent by a press. Alternatively, the band-shaped metal may be continuously passed through a roller on which a protrusion is formed to form the protrusion, and may be bent through a U-shaped base.

The construction wire mesh member to which the construction wire mesh holding member is applied will be described. FIG. 4 is a front view showing a construction wire mesh member. The construction wire mesh 7 is a polygonal wire mesh (for example, a rectangle, a trapezoid, a triangle, etc.), and is a rectangle in this example. Construction wire mesh holding members are attached to at least two opposing sides of the crimp wire mesh 7. For example, only the upper and lower sides and the left and right sides may be used. Here, the construction wire mesh holding member 1 is attached to all four sides of the rectangular crimp wire mesh 7, and both ends of the construction wire mesh holding member 1 are cut at an angle of 45 ° with respect to the length direction. It has a different shape. Or you may attach as shown in FIG. 5 using the construction metal-mesh holding member of the shape where both ends were cut at right angles as shown in FIG.

The crimp wire mesh will be described. It is a wire mesh that is formed by alternately combining metal wires that have been undulated by bending, and the size of the wire mesh depends on the size of the exhaust port and the louver frame to be attached. As a typical example, the linear shape is 1.6 mm, and the opening is 10 mm, 15 mm, 20 mm, or the like.

The material of the crimp wire mesh may be stainless steel or the like. Here, an example in which a steel wire is subjected to zinc-aluminum alloy plating and polyester resin baking coating will be described. After the zinc-aluminum alloy plating treatment was performed on the iron wire, a chemical conversion treatment was performed as a coating treatment, and undercoat baking coating was performed once, and further polyester resin baking coating was performed. By applying a heat-resistant paint, there is no ignition due to combustion. Moreover, since non-vinyl chloride resin is used, it does not generate dioxins and does not contain substances that are suspected of being an environmental hormone.

FIG. 6 is a cross-sectional view showing a state in which the building wire mesh holding member is attached to the building wire mesh. By simply inserting the edge of the building wire mesh 7 into the groove 4 of the building wire mesh holding member 1, it can be easily attached. Since the protrusion 5 protruding into the groove 4 presses the building wire mesh 7 from both directions, the building wire mesh 7 is held in a stable state. Here, in addition to fixing such that the construction wire mesh 7 does not move at all, it may be loosely fixed so that it can slide within the range of the mesh size. In this way, the building wire mesh 7 to which the building wire mesh holding member 1 is attached facilitates subsequent processes, and thus becomes a building wire mesh member with high added value.

FIG. 7 is a cross-sectional view showing a state in which the building wire mesh is attached to the gallery. In this example, since the bolt wire hole 6 is provided in the building metal mesh holding member 1, the bolt can be passed through the bolt hole 6 and easily attached to a sash frame or a vent of a building. For example, when attaching to the louver 11, in the conventional method, the plate is applied and fixed to the frame member 13 with screws 12. When this invention is applied, as shown in FIG. 7, it can be easily fixed to the frame member 13 of the gallery 11 through the screws 12 through the construction wire mesh holding member 1. Even if the metal wire for building 7 cannot be welded, it is made of zinc-aluminum alloy-plated steel plate, zinc-aluminum-magnesium alloy-plated steel plate, galvanized steel plate or steel plate coated with these plated steel plates, Alternatively, if the construction wire mesh holding member 1 is made of a stainless steel plate or the like, it can be easily fixed.
