[0007] Hereinafter, embodiments of the present invention will be described with reference to the drawings. Figures 1 to 4 show a first embodiment of a fence according to the present invention. This fence is installed at the boundary between a road and a site, and as shown in Figure 1, comprises posts 1, 1, 1 erected from the ground G at intervals in the left-right direction, and lattice units 4a, 4b attached to the road-side surfaces of the posts 1, 1, 1. The lattice units 4a, 4b have a plurality of furring strips 2, 2 arranged at intervals vertically, and a large number of lattices 3, 3, ... attached at intervals in the left-right direction to the road-facing surface of the furring strips 2, 2. The fence shown in FIG. 1 has two lattice units 4a, 4b attached to posts 1, 1, 1, with the furring strips 2, 2 of adjacent lattice units 4a, 4b connected by a connecting portion 6.

[0008] As shown in Figures 2 and 3, the support 1 is made of aluminum alloy extrusion and is hollow with a square cross section, and the lower part of the support 1 is reinforced by inserting a reinforcing material 7 into the hollow part. A cap 8 is fitted into the upper end of the support 1 to close the hollow part. The support 1 is a free support that can be installed in the left and right directions as needed depending on the conditions of the construction site, etc.

[0009] As shown in Figure 2, the furring strips 2 are made of aluminum alloy extrusions and are hollow and have a roughly rectangular cross section. The road side of the underside 2a of the furring strips 2 has engagement grooves 9 formed therein that engage with brackets 5 attached to the road side of the posts 1. The road side wall of the furring strips 2 hangs down below the underside 2a to form mounting portions 10 for the lattice 3. A roughly L-shaped bracket 5 is attached to the road-side surface of the support 1 with a bolt 11 inserted into the support 1 from the site side, and the underside 2a of the furring strip 2 is placed on the bracket 5, and the hook-shaped portion 12 formed at the tip of the bracket 5 is engaged with the engagement groove 9 of the furring strip 2, and the bolt 11 is tightened to pull and secure the furring strip 2 to the support 1. This allows the furring strip 2 to be fixed to the support 1 at any position in the longitudinal direction.

[0010] As shown in Figures 2 and 3, the lattice 3 is made of wood and formed into a square bar shape with a rectangular cross section that is longer in the front-to-back direction than in the left-to-right direction. The lattice 3 is abutted against the road-side surface of the furring strip 2 and is attached to the mounting part 10 of the furring strip 2 from the site side with wood screws 13. As shown in Figure 6, insertion holes 14 for the wood screws 13 are pre-formed at predetermined intervals in the mounting part 10 of the furring strip 2, and pilot holes 15 for the wood screws 13 are pre-formed in the lattice 3 at predetermined positions, so that the lattice 3 can be installed on-site from the site side using only a screwdriver (not shown).

[0011] As shown in Figure 4, the connecting portion 6 of adjacent lattice units 4a, 4b is formed by inserting a connecting fitting 16 with an approximately U-shaped cross section into the hollow portion at the end of the adjacent left and right furring strips 2, 2, and fastening it with a screw 17 from the site side to connect the furring strips 2, 2 together. A gap 18 of a specified dimension (3 mm) is formed between the left and right furring strips 2, 2, and this gap 18 is covered by attaching a furring strip connection cover 19 around the furring strips 2, 2. As shown in Figure 8, the furring strip connection cover 19 consists of two parts: an upper cover 19a formed by bending a metal plate into a U-shape, and a lower cover 19b formed by bending a metal plate into a crank shape. The upper cover 19a is placed over the connecting part 6 of the furring strips 2, 2 from above and adhered to the top of the furring strips 2, 2 with double-sided tape 20a. The lower cover 19b is placed over the connecting part 6 of the furring strips 2, 2 from below and fastened to the connecting fittings 16 with screws 21 from below. The upper cover 19a and lower cover 19b are attached to the property-side walls of the building using double-sided tape 20b.

[0012] Next, the construction procedure for this fence will be explained. First, as shown in FIG. 5-1(a), posts 1, 1, 1 are erected at intervals on the ground G. Then, brackets 5 are attached with bolts 11 to the road-facing surface of each post 1. Next, as shown in Figure 5-1(b), the lattice units 4a, 4b are assembled by attaching the lattices 3, 3, ... to the upper and lower furring strips 2, 2 with wood screws 13. The lattices 3, 3, ... are attached three at a time from both ends of the furring strips 2, 2 in the longitudinal direction. The reason for attaching the lattices 3, 3, ... to both ends of the furring strips 2, 2 in this way is that when the lattice units 4a, 4b are attached to the supports 1, 1, 1, within a range of approximately 300 mm from both ends, there is a possibility that they will overlap with the support 1 in the prospective direction. If they overlap with the support 1 in the prospective direction, the lattice 3 cannot be attached by screws from the site side. Therefore, by attaching the lattice 3 in advance in an area that may overlap with the support 1, this inconvenience is avoided. Next, as shown in Figure 5-1(c), the assembled lattice unit 4a is attached to the road-facing surfaces of the two posts 1,1 via brackets 5. To attach the lattice unit 4a, the bolts 11 (see Figure 2) attaching the brackets 5 are slightly loosened, the furring strip 2 is placed on the brackets 5, and the lattice unit 4a is temporarily placed in place, and after adjusting the left-right position of the lattice unit 4a, the bolts 11 are tightened to fix the lattice unit 4a. Since the wooden lattice 3 is heavy, if all the lattices 3, 3, ... are installed, the weight of the lattice units 4a, 4b becomes very heavy, making it difficult to install the lattice units 4a, 4b. However, since the lattice units 4a, 4b in this example have only three lattices 3, 3, ... installed from the ends of the furring strips 2, 2, the weight of the lattice units 4a, 4b is light, making it easy to install the lattice units 4a, 4b.

[0013] Next, as shown in Figure 5-2(d), a connecting bracket 16 is attached to the connecting end of the furring strips 2, 2 of the installed lattice unit 4a, and the other lattice unit 4b is temporarily placed on the support 1 via a bracket 5.Then, the lattice unit 4b is slid toward the previously installed lattice unit 4a to connect the ends of the furring strips 2, 2 with the connecting bracket 16. More specifically, as shown in Figure 7(a), the end of the furring strip 2 has an insertion hole 25 for a screw 17, and the connecting bracket 16 has female threaded holes 22a and 22b into which the screw 17 is threaded. The connecting bracket 16 is inserted into the end of the furring strip 2 of the previously installed lattice unit 4a and secured with the screw 17 from the site side. Then, as shown in Figure 7(b), the lattice unit 4b installed later is slid to insert the connecting bracket 16 into the end of the furring strip 2 of that lattice unit 4b, and secured with the screw 17 from the site side as shown in Figure 7(c). The female threaded hole 22b into which the screw 17 for securing the furring strip 2 of the subsequently installed lattice unit 4b is threaded is formed in a back plate 23 attached to the connecting bracket 16 so that its position can be adjusted left and right (reference numeral 24 in the figure denotes the screw that attaches the back plate to the connecting bracket 16). This allows the position of the female threaded hole 22b to be adjusted left and right. Thereafter, as shown in FIG. 8, a furring strip connection cover 19 is attached to cover the gap 18 between the furring strips 2, 2 of the adjacent lattice units 4a, 4b. Next, as shown in Figures 5-2(e) and (f), the lattices 3, 3, ... are attached to each lattice unit 4a, 4b in order from one side in the left-right direction. As mentioned above, the furring strips 2 have holes 14 for the wood screws 13 pre-formed at a predetermined pitch, and the lattices 3 have pilot holes 15 for the wood screws 13 pre-formed at predetermined positions, so the lattices 3, 3, ... can be easily attached from the site side using only a screwdriver.

[0014] In this way, this fence can be easily constructed by attaching the lattices 3 to both longitudinal ends of the furring strips 2,2, assembling the lattice units 4a,4b on site, hooking the furring strips 2,2 onto brackets 5 attached to the posts 1,1,1 to attach the lattice units 4a,4b, and then attaching the remaining lattices 3,3,... to the furring strips 2,2 from the site side. This construction method is particularly effective when the lattice 3 is made of wood and is heavy.

[0015] Figures 9 to 11 show a second embodiment of the fence according to the present invention, which differs from the first embodiment in the cross-sectional shape of the lattices 3, 3, .... In the fence of this embodiment, as shown in Figures 9 and 11, the lattices 3 are formed from strip-shaped wooden plates, and the lattices 3 are attached in a line along the length of the furring strips 2 with narrow gaps (5 mm) between them. This blocks views from the road side, providing greater shielding.

[0016] Figure 12 shows the fence in the middle of construction, when lattice units 4a, 4b have been attached to the posts 1, 1, 1. As shown in the figure, the lattice units 4a, 4b are attached to the posts 1, 1, 1 with three lattices 3, 3, ... attached from the end of the furring strip 2, just like in the first embodiment, and then the remaining lattices 3, 3, ... are attached to the furring strip 2 from the site side. By attaching three lattices 3, 3, ... to each end of the furring strip 2 to the lattice units 4a, 4b in advance, the supports 1, 1, 1 do not get in the way when the lattices 3, 3, ... are attached from the site side later.

[0017] As described above, the manufacturing method of this fence (first and second embodiments) comprises the steps of erecting the posts 1,1,1 at intervals, attaching lattices 3,3,... to both longitudinal ends of the furring strips 2,2 to assemble the lattice units 4a,4b, attaching the lattice units 4a,4b to the posts 1,1,1, and attaching the lattices 3,3,... to the longitudinal middle parts of the furring strips 2.2 of the lattice units 4a,4b (see Figures 5-1 and 5-2), which makes it easy to attach the lattice units 4a,4b and the lattices 3,3,..., thereby improving workability. This method of manufacturing the fence involves attaching the lattice units 4a, 4b by hooking the furring strips 2 onto the brackets 5 attached to the posts 1, 1, 1 (see Figures 2 and 10), making it even easier to attach the lattice units 4a, 4b to the posts 1, 1, 1, and further improving workability. Since the mounting positions of the lattice units 4a and 4b can be adjusted in the left-right direction, the lattice units 4a and 4b can be easily installed, further improving workability. The lattice units 4a, 4b have holes (insertion holes) 14 formed in advance for attaching the lattice 3 to the furring strip 2 (see Figure 6), making it easy to install the lattices 3, 3, ..., further improving workability. The lattice units 4a, 4b have the lattices 3, 3, ... pre-attached to the areas that may overlap with the posts 1, 1, 1 when they are attached to the posts 1, 1, 1 (see Figures 5-1, 5-2 and 12). Therefore, when the lattices 3, 3, ... are later attached to the lattice units 4a, 4b from the side where the posts 1, 1, 1 are located (the side of the site), the posts 1, 1, 1 do not get in the way, and the lattices 3, 3, ... can be easily attached. In this fence, the posts 1,1,1 and furring strips 2,2 are made of metal, and the lattices 3,3,... are made of wood, so that the metal posts 1 and furring strips 2 provide high strength and durability, while the wooden lattices 3,3,... provide a natural texture and warmth.

[0018] The present invention is not limited to the above-described embodiments. The cross-sectional shapes and materials of the posts, furring strips, and lattices can be changed as appropriate. The number of lattice units is arbitrary, and can be one or three or more lattices installed side by side. The lattice may be attached to the furring strip from the side opposite the posts (the road side). [Explanation of symbols]
