[0007] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Figures 1 to 5 show one embodiment of the construction device of the present invention. This construction device is applied to a fence installed at the boundary between a road and a residential site or next to a gate. As shown in Figure 1, this construction device has two pillars 1,1 erected from the ground G and a girder 5 erected on the upper ends of the pillars 1,1 to form a gate-shaped frame, and a number of horizontal lattices 3,3,... are arranged at intervals in the vertical direction on the visible surfaces of the frame on the road side and the site side, and end horizontal lattices (erecting members) 4,4,... are arranged on both the left and right sides so as to connect the longitudinal ends of each horizontal lattice 3,3,... on the road side to the longitudinal ends of each horizontal lattice 3,3,... on the site side.

[0008] The pillar 1 is formed from an extruded aluminum alloy material, and as shown in FIG. 2, is formed into a hollow shape with a square cross section. The girder 5 is formed from an extruded aluminum alloy material, and as shown in Fig. 4, has a hollow portion 6 with a rectangular cross section and a recess 7 that opens downward below the hollow portion 6, which continues in the longitudinal direction. A lid 8 (see Fig. 3) is attached to the longitudinal end of the girder 5, and the lid 8 closes the end of the girder 5. As shown in Figures 3 and 4, the upper end of the pillar 1 is inserted into the recess 7 of the girder 5 and fixed to the bottom wall of the recess 7 via metal fittings 25. The recess 7 of the girder 5 is closed by fitting a batten 9 from below, except for the part where the pillar 1 is inserted.

[0009] As shown in Figures 1 and 4, the horizontal lattices 3, 3, ... attached to the facing surface 10 of the pillar 1 on the road side and the site side are composed of lattice units 2, 2, ... each consisting of multiple horizontal lattices 3, 3, ... stacked one on top of the other. In Figure 1, the lattice units 2 are installed in six layers, with the lattice units 2 in the first to fifth layers from the bottom being the same units consisting of six horizontal lattices 3, and the lattice unit 2 in the topmost layer consisting of seven horizontal lattices 3.

[0010] As shown in Figures 2, 4 and 6, each lattice unit 2 is constructed by arranging multiple horizontal lattices 3, 3, ... at intervals in the vertical direction, and screwing the longitudinal ends of each horizontal lattice 3, 3, ... to two furring strips 26, 26 arranged vertically in a position facing the visible surface 10 of the pillars 1, 1 with screws 11 from behind. As shown in Fig. 4, the horizontal lattice 3 is made of an aluminum alloy extrusion material and is hollow with a rectangular cross section, and as shown in Fig. 2, both left and right ends protrude laterally beyond the pillars 1. Both left and right ends of the horizontal lattice 3 are left cut (see Fig. 6). The furring strip 26 is formed from an extruded aluminum alloy material, and as shown in FIG. 2, is a long material with a roughly C-shaped cross section with an open face on the column 1 side. As shown in Figure 4, the second-highest and second-lowest horizontal lattices 3 of the lattice unit 2 are horizontal lattices with battens 3a, which are made up of two components: a main body 27 with a roughly rectangular cross section, and a batten 13 with a roughly U-shaped cross section that is detachably attached to the front of the main body 27. The other horizontal lattices 3 are horizontal lattices 3b without battens. As shown in Figures 2 and 4, each lattice unit 2 is attached to the pillar 1 by abutting the rear surface of the furring strip 26 against the visible surface 10 of the pillar 1 and screwing the horizontal lattices with battens 3a to the pillar 1 with screws 14 from the front.

[0011] As shown in Figure 4, a support bracket 15 that supports the lower end of the furring strips 26 of each lattice unit 2 is attached to the pillar 1. The support bracket 15 is a substantially L-shaped metal fitting that has an attachment piece 17 that abuts against the visible surface 10 of the pillar 1 and is fixed with a screw 16, and a support piece 18 on which the lower end of the furring strip 26 is placed.

[0012] Next, the procedure for installing the lattice units 2, 2, ... will be explained. First, as shown in Figure 7-1 (a), the support bracket 15 is attached at a specified height on the visible surface 10 of the pillar 1, and the lower end of the furring strip 26 of the assembled lattice unit 2 is placed on the support piece 18 of the support bracket 15, and the rear surface of the furring strip 26 is abutted against the visible surface 10 of the pillar 1. Note that the battens 13 of the horizontal lattice with battens 3a are removed in advance. Next, as shown in Figure 7-1(b), the horizontal lattice 3a with battens is fixed to the pillar 1 together with the furring strips 26 with the screws 14 from the front. The lower end of the furring strips 26 of the lattice unit 2 is placed on the support pieces 18 of the support brackets 15, so that the lattice unit 2 is held at a specified height and there is no need to hold the lattice unit 2 up by hand, making it easy to screw it into the pillar 1. After that, the battens 13 are attached to the horizontal lattice 3a to hide the screws 14. Next, as shown in FIG. 7-1(c), the support piece 18 is abutted against the upper end of the furring strip 26, and the support bracket 15 is attached to the visible surface 10 of the pillar 1. Next, as shown in Figure 7-2 (d), the lower end of the furring strip 26 of the second row of lattice units 2 is placed on the support piece 18 of the support bracket 15, and the rear surface of the furring strip 26 is abutted against the visible surface 10 of the pillar 1. Next, as shown in Fig. 7-2(e), the horizontal lattice 3a with the battens is fixed to the pillar 1 together with the furring strips 26 by the screws 14 from the front. After that, the battens 13 are attached to the horizontal lattice 3a to hide the screws 14. Next, as shown in FIG. 7-2(f), the support piece 18 is abutted against the upper end of the furring strip 26, and the support bracket 15 is attached to the visible surface 10 of the pillar 1. Similarly, the lattice units 2, 2, ... for the third to sixth rows are attached.

[0013] In this structure, as shown in Figures 1 and 4, horizontal lattices 3 are also attached to the visible surfaces 21 of the girder 5 on the road side and the site side. As shown in Figure 4, the horizontal lattice 3 is a horizontal lattice 3a with a batten, and is attached to the girder 5 with screws 22 inserted from the front side, and the screws 22 are hidden by the batten 13. By sandwiching a spacer 23 between the rear surface of the horizontal lattice 3 and the girder 5, the visible surface of the horizontal lattice 3 attached to the girder 5 and the visible surface of the horizontal lattice 3 of the lattice unit 2 are flush with each other. In this way, by attaching the horizontal lattice 3 to the girder 5 as well, the girder 5 becomes less noticeable, improving the design.

[0014] As shown in Figure 2, a pair of supports 28, 28 are attached to the rear walls of both the left and right ends of each horizontal lattice 3, 3, ... on the road side and site side, and the end horizontal lattice 4 is attached across the pair of supports 28, 28. The support 28 has a mounting piece 37 that abuts against the inner surface of the rear wall of the horizontal lattice 3 and is attached with a screw 29, a support piece 38 that extends rearward from the mounting piece 37, and a cover mounting piece 39 that extends forward from the mounting piece 37.

[0015] The end horizontal grille 4 is formed from the same shape material as the horizontal grille with battens 3a described above, and as shown in Figure 3, is formed from two components: a hollow main body 27 with a roughly rectangular cross-section, and a batten 13 that is engaged and attached to the main body 27. As shown in Fig. 2, the main body 27 is cut to fit the dimension between the rear side of the horizontal lattice 3 on the road side and the rear side of the horizontal lattice 3 on the site side. As shown in Fig. 5, the main body 27 has slits 41, 41 formed in an upper position of the outer wall 40 from both longitudinal ends toward the center. Also, slits 42, 42 shorter than the slits 41, 41 are formed in the vertical center of the outer wall 40 of the main body 27. As shown in Figures 2, 3 and 5, the main body 27 is attached between the supports 28, 28 by abutting the support pieces 38, 38 of a pair of supports 28, 28 against the inner surface of the outer wall 40 and threading a screw 43 inserted through the shorter slit 42, 42 from the outside into a female threaded hole 44 formed in the support piece 38.

[0016] As shown in Figure 2, the batten 13 is cut to fit the dimension between the front side of the horizontal grille 3 on the road side and the front side of the horizontal grille 3 on the site side, and both longitudinal ends are cut out in a stepped shape so that the edges 36 of the horizontal grille 3 can fit into them, forming cap portions 32 that cover the edges 36 of the horizontal grille 3. By attaching the batten 13 to the main body 27, as shown in Figure 5, the slits 41, 42 of the main body 27 and the fixing parts provided by the screws 43 are hidden by the batten 13, and the edges 36 of the horizontal grille 3 on the road side and site side are hidden by the cap portions 32 of the batten 13.

[0017] 2, a cover 30 made by bending a thin metal plate is attached to the end horizontal grille 4 in order to hide the cut edges of the main body 27 and the batten 13. The cover 30 is attached to the cover mounting piece 39 of the support member 28 with a screw 45.

[0018] Next, we will explain the procedure for installing the end horizontal lattice 4. First, as shown in Figure 8-1(a), the supports 28, 28 are attached in advance to both the left and right ends of the horizontal lattice 3, 3 on the road side and the site side, and the cover 30 is attached to the cover mounting pieces 39 of the supports 28, 28 with screws 45. Next, as shown in FIG. 8-1(b), hold the main body 27 with the side on which the slits 41,41 are formed facing up, and move the main body 27 from below up the supports 28,28 to pass the support pieces 38,38 of the supports 28,28 through the slits 41,41 of the main body 27, and position the support pieces 38,38 within the hollow portion of the main body 27. Next, as shown in FIG. 8-2(c), the main body 27 is rotated 90 degrees clockwise so that the surface on which the slits 41, 41 are formed faces outward, and then the main body 27 is temporarily placed between the support pieces 38, 38. Next, as shown in Figure 8-2 (d), the support pieces 38, 38 are abutted against the inner surface of the outer wall 40 of the main body 27, and the screws 43, 43 inserted from the outside through the slits 42, 42 of the main body 27 are screwed into the female threaded holes 44 formed in the support pieces 38, 38, to fix the main body 27. Finally, as shown in FIG. 8-3(e), the batten 13 is attached to the main body 27 from the outside.

[0019] In this way, this building device makes it easy to install the end horizontal grille 4 between the horizontal grilles 3, 3 on the road side and site side that have been installed at a specified interval in advance. By positioning the support pieces 38, 38 inside the hollow portion of the end horizontal grille 4 and abutting the support pieces 38, 38 against the inner surface of the outer wall 40 of the main body 27 of the end horizontal grille 4 and fixing them with screws 43, 43 (see Figure 2), the screws 43, 43 can be made shorter than when the support pieces 38, 38 are not placed inside the hollow portion of the end horizontal grille 4 but abut against the inner surface of the main body 27 and fixed with screws that penetrate the main body 27, and the end horizontal grille 4 can be installed more firmly.

[0020] As described above, this construction device comprises a pair of supports 28, 28 and an erection member (end horizontal lattice) 4, the pair of supports 28, 28 are arranged at a distance from each other, and the erection member 4 is attached across the pair of supports 28, 28. It has a hollow shape and has slits 41, 41 formed from both longitudinal ends toward the center. By passing the supports 28, 28 through the slits 41, 41 on both sides of the erection member 4, the supports 28, 28 are positioned within the hollow portion of the erection member 4, and the erection member 4 is rotated to abut and fix the supports 28, 28 against the inner surface of the erection member 4 (see Figures 8-1 and 8-2), so that the erection member 4 can be easily attached across the pair of supports 28, 28, simplifying construction. The installation member 4 has a batten 13 which hides the fixed parts with the supports 28, 28 (see Figures 5 and 8-3), which not only gives a good design but also prevents the installation member 4 from being removed without permission. The erection member 4 has slits 41, 41 formed on the surface hidden by the batten 13 (see Figs. 5 and 8-3), so that the slits 41, 41 are not exposed to the outside, improving the design. In this construction device, the support materials 28, 28 can be passed through the slits 41.41 and positioned within the hollow portion of the erection member 4, so that the erection member 4 can be temporarily placed between the support materials 28, 28, making it even easier to install the erection member 4 and further improving workability.

[0021] The present invention is not limited to the above-described embodiment. The shape and material of the support material and the installation member can be changed as appropriate. The installation member does not necessarily have a batten. If the installation member does not have a batten, the slits are placed in a position (e.g., the rear surface) where they are not noticeable when the installation member is installed. The present invention is not limited to fence lattices, but can be applied to various building components, and is effective, for example, in cases where horizontal members are installed later between vertical members that have already been installed at regular intervals on a building frame or the like.
