Description

  The present invention relates to a fence in which a lattice body is attached to a front surface of a support column erected at an appropriate interval via an attachment fitting.

  Conventionally, as a method of attaching a lattice body composed of vertical and horizontal wires to a support column, a threaded portion is provided with one end curved and a nut screwed into the other end of a support column standing at substantially the same interval. A method using a tilted J-shaped fixing bolt has been proposed. Specifically, pass this fixing bolt in the front-rear direction of the support, hook the horizontal wire of the grid near the base of the curved part at one end, and screw the nut to the screw part at the other end and fasten it to the support Thus, the horizontal wire is fixed to the front surface of the column. However, according to this method, the operator needs to perform the work of attaching the lattice body on the front side of the support and the fastening work on the rear side of the support, and the construction work is troublesome.

  In Patent Document 1, a grid-like fence body is placed along a column, and a horizontal line at the top of the fence body is hooked on a hook of a mounting bracket attached to the top of the column. In the fence in which the fence body is fastened and attached to the support column, the hook part of the mounting bracket is formed in a substantially U shape that opens upward, and the parallel U-shaped hooks on both sides of the substantially U-shaped hook part are formed. There has been proposed a fence characterized in that one side piece extends along a fence post and an inclined guide piece extending obliquely upward from the upper end of the other side piece is continuously provided. With the inclined guide piece, the horizontal line of the fence body can be easily hooked on the hook portion.

  However, since the fence of Patent Document 1 requires a fastener such as a bolt at the time of construction, the fastening may be loosened over time, and the fence body may be rattled. When inserted between parallel side pieces, the distance between the side pieces and the diameter of the horizontal line to be inserted are relatively tightly held between the place where the horizontal line is held between the side pieces relatively firmly. Therefore, at a location that is relatively loosely held, the holding state is further loosened due to a shocking load applied to the grid, a downward load due to snow accumulation, a load applied over time, etc. There was a possibility that it would come off between the side pieces, and that was the problem.

  The present invention solves the above-described problems, and is intended to provide a fence in which a grid body can be easily attached to a support and the attached grid is not easily detached from the support.

  Next, the relationship between the mounting bracket 3 and the cover material 4 will be described in detail. As shown in FIG. 4, locking concave portions 35 that are recessed toward the center side of the mounting portion 31 are respectively provided at both end portions of the mounting portion 31 of the mounting bracket 3. The cover member 4 is attached to the cover member 3 by locking the engaging piece 42 of the cover member 4 to the locking recess 35.

  FIG. 7 is an explanatory view for explaining the relationship between the mounting bracket 3 and the cover material 4, and (a) is a cross-sectional view of the mounting bracket 3 shown in FIG. 4 taken along line AA and a cover corresponding to the height position. FIG. 4 is a cross-sectional view of a material 4 Both locking recesses 35 of the mounting bracket 3 are provided with stepped portions 35a in which the outer wall portion on the support column 1 side of the mounting portion 31 is further recessed toward the center side. The claw portions 43 of the cover member 4 disposed on the rising piece 33 side of the mounting bracket 3 are engaged with the step portions 35a on both sides, and the engagement of the mounting bracket 3 is between the pair of engaging pieces 42. The cover material 4 is locked to the mounting bracket 3 by elastically sandwiching the outer wall portion of the retaining recess 35 (b). Thereby, the grid body 2 can be fixed to the support column 1 by the mounting bracket 3 and the cover material 4 without using a fastener such as a bolt when constructing the fence P. Further, since the cover member 4 can be locked to the mounting bracket 3 from the side on which the grid body 2 is fixed with respect to the support column 1, it is not necessary to work around the back side of the support column 1 and workability can be improved. .

  FIG. 8 is an enlarged exploded view of the BB cross section of FIG. 1, and is an explanatory view showing a mounting structure of the horizontal wire 22 to the mounting bracket 3. (A) is explanatory drawing before attachment, (b) is explanatory drawing after attachment, (c) is explanatory drawing of the state which latched the cover material 4 to this attachment metal fitting 3. FIG. First, the horizontal wire 22 is inserted into the receiving portion 34 of the mounting bracket 3 (a, b), and then the cover material 4 is locked to the mounting bracket 3 from the rising piece 33 side of the receiving portion 34 (c). As shown to (b), in this embodiment, the top part 36 is protrudingly provided toward the front of the support | pillar 1 in which the receiving part 34 is formed from the upper part of the attachment part 3 of the attachment metal fitting 3. FIG. Accordingly, when the fence P is installed, if the horizontal wire 22 is inserted into the receiving portion 34, the horizontal wire 22 moves upward due to vibration associated with the construction work or when the operator contacts the grid body 2. Even so, since the upward movement is prevented by the top portion 36, the horizontal wire 22 does not easily fall from the receiving portion 34.

  Further, as shown in FIG. 8C, the cover material body 41 of the cover material 4 closes the gap between the top portion 36 of the mounting bracket 3 and the rising piece 33, so that the horizontal wire 22 is opened to the receiving portion 34. It will not come off from the club side. In addition, the locking piece 42 of the cover material 4 is locked to the locking recess 35 of the mounting portion 31 across the opening of the receiving portion 34 from the rising piece 33 side toward the mounting portion 31 side. The upward movement of the horizontal wire 22 can be prevented.

  FIGS. 9A and 9B are explanatory views when the crossing portion 23 of the lattice body 2 is attached to the attachment fitting 3, wherein FIG. 9A is a front view and FIG. 9B is a CC cross-sectional view. The receiving portion 34 of the mounting bracket 3 is formed on the left and right sides of the mounting bracket 3 at intervals. Therefore, by inserting the horizontal wire 22 near the intersecting portion 23 of the grid 2 into the receiving portion 34 and arranging the vertical wire 21 forming the intersecting portion 23 between the receiving portions 34, the vertical wire 21 is Since the movement in the left-right direction is restricted by the inner end portion 34a of the receiving portion 34 and is locked to the inner end portion 34a, the horizontal wire 22 does not fall out of the outer end portion 38 of the receiving portion 34 and passes through the intersecting portion 23. It can be attached to the mounting bracket 3.

  There is no particular limitation between the two receiving portions 34 formed at intervals in the mounting bracket 3 as long as the vertical wire 21 can be arranged, but in this embodiment, the rising piece 33 extends vertically. And the bottom 32 remains. As a result, when a horizontal load is applied in the front-rear direction of the grid 2 attached to the mounting bracket 3, the cross-section is substantially U-shaped in the longitudinal direction of the mounting bracket 3. The horizontal wire 22 inserted into the receiving portion 34 is not easily detached because the deformation to the front side or the rear side and the downward deformation of the bottom portion 32 of the receiving portion 34 are suppressed.

  Further, the bottom portion 32 between the two receiving portions 34 of the mounting bracket 3 is provided with a cutout portion 32a with the cut-out rising piece 33 side facing the attachment portion 31 side. Further, a notch 36 a is formed from the tip of the top 36 toward the mounting portion 31 so as to correspond to the notch 32 a at the top 36 of the mounting bracket 3. Thereby, the back-and-forth movement of the crossing portion 23 of the lattice disposed in the receiving portion 34 is notched where the inner wall surface of the rising piece 33 of the receiving portion 34 that the front side of the horizontal wire 22 contacts and the rear side of the vertical wire 21 contact. It is regulated between the front wall surfaces of 32a and 36a. Therefore, if the notch depths of the notches 32a and 36a are set according to the penetration of the vertical wire 21 and the horizontal wire 22 at the intersection 23 and the thickness of the coating resin, the longitudinal direction of the intersection 23 is determined. The rattling can be suppressed.

  FIGS. 10A and 10B are explanatory views when two intersecting portions 23 of the lattice body are attached to the attachment fitting 3, wherein FIG. 10A is a cross-sectional view of the main part, and FIG. 10B is an EE cross-sectional view. In the two left and right grid bodies 2, the vertical wire 21 at the side end adjacent to each other is disposed between the receiving portions 34, and the horizontal wire 22 intersecting the vertical wire 21 is inserted into the left and right receiving portions 34, respectively. It becomes easy to connect the grid body 2 in the left-right direction via the mounting bracket 3 attached to the column 1 as shown in FIGS.

  In this way, in order to connect the two grid bodies 2 to the left and right using one mounting bracket 3, the distance between the left and right receiving portions 34 of the mounting bracket 3 is set to the outer diameter of at least two vertical wires 21. What is necessary is just to set it as the dimension which added the sum of the protrusion dimension of the horizontal wire 22 which protrudes from the cross | intersection part 23 of each vertical wire 21. FIG.

  Further, the cover member 4 is provided with a recess 44 in which the central portion of the cover member body 41 is recessed toward the side opposite to the locking piece 42. Accordingly, as shown in FIG. 10, the center portion of the cover material main body 41 is spaced from the vertical wire material 21 by the recess 44, so that when the cover material 4 is locked to the mounting bracket 3, the cover material main body 41 Even if the center portion of 41 is pressed toward the mounting bracket 3 and the interval between the tips of the locking pieces 42 is increased, the cover material main body 41 and the vertical wire material 21 are difficult to contact with each other. It becomes easy.

  FIG. 11 is a plan view showing a deformation of the cover material 4. Compared to the cover material 4 shown in FIG. 6, the center of the cover material main body 41 has a plurality of cross-sectional mountain-shaped projections 45 protruding in the same direction as the protruding direction of the locking piece 42. It is different and the other points are the same. That is, since the vertical wire 21 can be pressed toward the mounting portion 31 by the protruding piece 45, the movement of the two vertical wires 21 arranged on the left and right receiving portions 34 of the mounting bracket 3 in the left-right direction is prevented. It is possible to prevent such a problem that a passerby mistakes a finger between two vertical wires 21. In this embodiment, the projecting piece 45 is formed by bending the upper and lower ends of the cover material body 41 in the same direction as the locking piece 42, and the cover material 4 can be formed from a single metal piece by pressing. Therefore, it is preferable that the protrusion 45 is separately formed and attached to the cover member 4.

  12A and 12B are explanatory views showing another embodiment of the fence P according to the present invention, in which FIG. 12A is a front view of a main part, and FIG. That is, the spacer 5 is disposed between the horizontal wire inserted in the receiving portion 34 of the mounting bracket 3 and the top portion 36 of the mounting bracket 3. This prevents the horizontal wire 22 from moving upward, and also prevents the horizontal wire 22 from tilting in the vertical direction with the bottom 32 on the outer end side of the receiving portion 34 as a fulcrum. The rotation of the metal fitting 3 can be suppressed. Further, when the horizontal wires 22 of the two grid bodies 2 are attached to one mounting bracket 3, if the left and right dimensions of the spacer 5 are made longer than the left and right dimensions of the notch portion 37 of the mounting bracket 3, both horizontal wires 22. The upward movement and inclination of the mounting bracket 3 can be prevented, and the rotation of the mounting bracket 3 can be suppressed.

  Such a spacer 5 may be used for each of the mounting brackets 3 fixed to the support column 1. However, if the spacer 5 is used for at least the mounting bracket 3 positioned at the uppermost stage, the spacer 5 of the grid body 2 fixed to the support column 1 is used. The upward movement can be effectively suppressed.

  FIG. 13 is an explanatory view showing another modification of the cover material 4 and is an enlarged view of the GG cross section of FIG. When the upper portion of the vertical wire 21 attached to the mounting bracket 2 is inclined toward the front of the column 1, the central portion of the cover material main body 41 is prevented from contacting the inclined vertical wire 21 and the cover material 4. You may provide the notch part 46 notched toward the downward direction from the upper end. Although not shown, when the lower portion of the vertical wire 21 is inclined toward the front of the column 1, a similar notch may be provided at the lower end of the central portion of the cover material body 41.

  The fence P according to the present invention attaches the adjacent crossing portions 23 of the side end portions of the left and right grid bodies 2 to the support column 1 via the mounting bracket 3. It is also possible to attach a horizontal wire 22 between the vertical wires 21 at the center of 2 or an intersection 23 of the intermediate portion of the grid 2. Therefore, by using the mounting bracket 3, it is possible to mount the central portion of the lattice body to the support column using the mounting bracket.
