Description

  The present invention relates to a fence having a main surface made of wood and an assembling method thereof, and more particularly, to a fence made of thinned wood.

  Protective fences provided on the side of the road and fences for preventing small animal intrusion in hills are generally constructed with metal nets stretched on metal columns, with emphasis on strength and service life. . And, on highways, these fences may be continuously provided on both sides of the road, and it was never a good environment for scenery. In addition, there is a case where a color is added to the concrete fence to improve the landscape, but in any case, an inorganic and artificial impression has to be strengthened.

  Therefore, recently, a protective fence using a wooden beam (Patent Document 1), a protective fence using a wooden material as a covering member (Patent Document 2), and the like have been developed. In the former technique, a beam support bracket is provided on the inner side of a support column erected along the road side of the road, and this bracket is provided with a cylindrical cover that opens toward adjacent columns. The structure is such that the cylindrical cover is connected so as to cover the ends in a state where the ends of the wood beams extended from the respective columns are abutted with each other, and the tip of the wood beam is fitted into the cylindrical cover In this state, the bolt was inserted and fixed by fastening with the nut. In the latter technique, upper, middle and lower three-level horizontal beams are connected between columns arranged at predetermined intervals, and vertical beams are connected to the upper and lower sides of the horizontal beams to form a lattice shape. In this case, a wooden material is bonded to the surface of each member (post, horizontal beam and vertical beam).

On the other hand, in terms of the environment, the use of wood is attracting attention in order to contribute to the prevention of global warming due to carbon fixation and the formation of a recycling-oriented society as a resource that can be reproduced. Is being recommended. As part of this, the use of thinned wood is given priority in afforestation projects, and plans to use it preferentially in public works are also being made (see Non-Patent Document 1).
Japanese Patent Laying-Open No. 2004-100384 (page 4-5, FIGS. 1 to 3) JP-A-8-302631 (page 2-3, FIG. 1) Issued by Aichi Prefecture in March 2004 “Aichi-ki Plan-Effort Plan for Promoting the Use of Timber (FY2004-FY18)” (pages 1-14-15)

  All of the above prior arts are protective fences, so that sufficient strength is required, and the mounting structure has to be complicated. In particular, in the former prior art, the wooden beams are penetrated with bolts, and in order to remove each wooden beam, each through bolt must be detached, and in the latter prior art, Since the wood material is bonded to each member, removing them means that each member is replaced, and it is very troublesome to replace not only the horizontal beam and vertical beam but also the column. It was. Therefore, these protective fences were not intended to replace wooden parts. However, since the material used is wood, it corrodes when used for a long time or is devastated by insect worms. Even if it is coated with an insecticidal or antiseptic effect, it is as long as a metal member. The service life could not be obtained, and after all, it was difficult to remove the wooden beam or the wood material, and if it was replaced, it took time and labor. Therefore, a fence having a structure that can be easily replaced is desired.

  Moreover, since all the above prior arts are premised on use as a protective fence, wooden members are used as beams or cross beams. However, in order to improve the landscape, it is preferable to use it as a vertical member, and when building a fence with a predetermined height, the number of wooden beams and cross beams must be increased. The replacement work required more time and effort.

  In some cases where thinned wood is used in public works, there is a fence that prevents glare. In this case, the foundation is constructed by driving into the ground like a pile or constructed. It is expected that this is due to a method of being fixedly installed on the wall, but the replacement is not easy, and it takes a long time for the fixing work, and it is difficult to provide a wide range.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. The outline of 1st embodiment concerning a wooden fence is shown in FIG. As shown in this figure, the wooden fence F is configured such that a horizontal beam 10 is horizontally mounted between columns 20 and a vertical member 30 is supported on the horizontal beam. The struts 20 are driven into the ground at an appropriate interval, and this interval is usually 2 m, but can be appropriately changed depending on installation conditions and the like. Each member 10, 20, 30 can be made of wood, but from the viewpoint of strength and workability, the transverse beam 10 and the support column 20 are made of metal, and the longitudinal member 30 that forms most of the fence F is formed. Only can be made of wood.

  As shown in FIG. 2, the transverse beam 10 is composed of transverse beam constituting members 40 and 50, and a single transverse beam is constituted by integrally connecting the two transverse beam constituting members 40 and 50. Is. Further, the transverse beam constituent members 40 and 50 in the present embodiment are configured by bending a metal plate-like member into a substantially U-shaped cross section, and the open side edge 41 of one of the transverse beam constituent members 40. 42, the open side edges 51 and 52 of the other transverse beam constituting member 50 are arranged to face each other, whereby the beam 10 like a generally square steel pipe can be formed. is there.

  The transverse beam constituent members 40 and 50 are configured in a symmetrical shape, that is, the end edges 41, 42, 51 and 52 are appropriately spaced in the longitudinal direction of the transverse beam constituent members 40 and 50. Longitudinal material abutting portions 43, 44, 53, 54 are formed at the same intervals at positions where the transverse beam constituting members 40, 50 face each other.

  The vertical member 30 is composed of a long rod-shaped member having a substantially square cross section. In the present embodiment, the longitudinal member 30 is composed of a wooden member made from thinned wood. Engaging grooves 31 a, 32 a, 31 b, and 32 b are provided on the surface of the vertical member 30 where the edges 41, 42, 51, 52 of the transverse beam constituting members 40, 50 abut.

  Therefore, as shown in FIG. 3, the two transverse beam constituting members 40 and 50 can sandwich the longitudinal member 30 from both sides, and in this state, the two transverse beam constituting members 40 and 50 are firmly connected. At the same time as the integral transverse beam 10 is formed, the longitudinal member 30 is supported at a predetermined interval in the transverse beam 10. At this time, the engaging grooves 31 a and 32 a (FIG. 2) provided on one side surface (the back side surface) of the vertical member 30 are formed so that a part of the vertical member contact portions 43 and 44 of one horizontal beam constituting member 40 is formed. Engaging grooves 31 b and 32 b (FIG. 2) provided on the opposite surface (front surface) of the longitudinal member 30 are engaged with the longitudinal member abutting portions 53 and 54 of the other transverse beam constituting member 50. Part of will be in attendance.

  Here, the above engagement will be described in detail. As shown in FIG. 4, the open side edges 41, 50 of the transverse beam constituting members 40, 50 abutted on both surfaces 34, 35 of the longitudinal member 30, respectively. Engaging grooves 31a, 32a, 31b, and 32b are provided so as to coincide with the width dimensions of 42, 51, and 52 (see FIG. 4A). Further, the vertical member abutting portions 43, 44, 53, 54 provided on the open side edges 41, 42, 51, 52 of the horizontal beam constituting members 40, 50 are matched with the horizontal width dimension of the vertical member 30. Each is formed by a U-shaped notch (see FIG. 4B). Therefore, as shown in FIG. 5, when the two transverse beam constituting members 40 and 50 are brought close to each other while facing each other, the opposed upper vertical material contact portions 43 and 53 and the lower vertical material contact portion 44 are arranged. , 54 form a similar substantially quadrilateral shape, and the vertical member 30 is inserted into the substantially quadrilateral shape (see FIG. 5A). As a result, the side surfaces 36 and 37 (FIG. 4) of the vertical member 30 inserted through the substantially quadrilateral portion are the side edge portions 43a, 43b, 53a, which are part of the vertical material contact portions 44 and 54, respectively. 43b, and the transverse beam constituting members 40, 50 are positioned in the longitudinal direction. Further, in the engaging grooves 31a, 32a, 31b, 32b of the vertical member 30, the engaging piece portion 43c located at the innermost part of the vertical member abutting portions 43, 44, 53, 54 of the transverse beam constituting members 40, 50 is provided. 53c are engaged. As a result, the front and back surfaces 34 and 35 of the vertical member 30 are respectively hooked by the engaging piece portions 43c, 44c, 53c, and 54c at two positions in the vertical direction, and are positioned in the vertical direction ( (Refer FIG.5 (b)).

  As described above, since the vertical member 30 is sandwiched between the horizontal beam constituent members 40 and 50, it is possible to connect the vertical member 30 to the horizontal beam 10 without using a connecting bracket or the like. is there. Then, as shown in FIG. 2, by providing a plurality of vertical member abutting portions 43, 44, 53, 54 in the transverse beam constituent members 40, 50 at appropriate intervals in advance, the vertical member abutting portions 43, 44 are provided. , 53 and 54, a plurality of vertical members 30 can be simultaneously supported, and the vertical members 30 having a predetermined interval can be installed.

  The transverse beam constituting members 40 and 50 are fixed to the support column 10, and this fixing is firmly performed by a predetermined connecting metal fitting. As an example of the connecting structure at this time, as shown in FIG. In this case, holes through which the through bolts 11 can be penetrated are formed at predetermined positions of the support column 10 and both the transverse beam constituting members 40, 50, and the through bolts are used to fix the through bolts 11. Is to be made.

  Here, first, only one transverse beam constituting member 40 is fixed to the support column 10 first. At this time, the spacer 13 is provided in the middle between the transverse beam constituting member 40 and the support column 10, and the transverse beam constituting member 40 is fixed at a predetermined interval from the support column 10. Further, since the transverse beam constituting member 40 is supported by the support column 10 in a state separated from the other transverse beam constituting member 50, first, the through bolt 11 is inserted from the back side of the support column 10, and the transverse beam is mounted. Only one of the transverse beam constituting members 40 can be fixed by projecting the first nut 12 to the bolt 11 and projecting the first nut 12 to the bolt 11 (see FIG. 6A).

  Finally, the other transverse beam constituting member 50 is attached. At this time, the through bolt 11 that has already fastened one transverse beam constituting member 40 penetrates the other transverse beam constituting member 50. The transverse beam constituting member 50 is mounted so as to penetrate the hole. By screwing the second nut 12 into the through bolt 11 from the outside of the transverse beam constituent member 50 in such a state, the other transverse beam constituent member 50 can also be fixed.

  Next, a method for assembling the fence according to the above embodiment will be described. The outline of the assembly method is shown in FIGS. As shown in this figure, a support column 20 is erected to support the entire fence (see FIG. 7A). The distance between the centers of the columns 20 is adjusted to be 2 m, but the distance can be changed. The upright of the support column 20 may be driven by a driving method using a pile driving machine, backfilled to a shaft, or supported by a concrete foundation.

  Next, one horizontal beam constituting member 40 is placed between the columns 20 (see FIG. 7B). The transverse beam constituting member 40 is basically configured to have a span of 2 m, and those having different lengths can be used. In this state, the vertical member abutting portions 43 and 44 of the transverse beam constituting member 40 are aligned toward the front side of the fence. Therefore, next, the longitudinal member 30 is temporarily fixed to the transverse beam constituting member 40 (see FIG. 8A). As described above, this temporary fixing is performed by engaging the engaging grooves 31a of the longitudinal member 30 with the engaging piece portion 43c of the transverse beam constituting member 40.

  After the above-described temporary fixing is performed on all the vertical members 30, the other horizontal beam constituent member 50 is fixed so as to sandwich the vertical member 30 so as to face the horizontal beam constituent member 40 that has already been installed horizontally. (See FIG. 8B). Thus, by fixing the other transverse beam constituent member 50 to the one transverse beam constituent member 40 so as to face each other, the constituent members 40 and 50 are overlapped with each other to form an integral transverse beam 20. (See FIG. 1).

  As described above, the fence F in a flat place can be constructed. Next, when installing on a sloped place like the slope of an expressway, the vertical members are lowered (or raised) in stages, and the adjacent vertical members are connected by a transverse beam. It is also possible to maintain the integrity of the above. That is, as shown in FIG. 9, the column 20 can be erected with a short span on the slope, and the longitudinal member 30 can be supported by the transverse beam 10 in the same manner as in the flat case described above. In this case, as the transverse beam constituting members 40 and 50, a short member corresponding to the span in which the support column 20 is provided is used. And in the said structure, since a big gap | interval will arise between the lower end of the vertical member 30, and a slope, when using it as a fence for animal protection, as shown with a dashed-dotted line in a figure, it is stepwise. It is also possible to use a longitudinal member 30 having a length changed.

  As another construction method, as shown in FIG. 10, two struts 20 are erected on a relatively long span of a slope, and the middle is divided into several sections (four sections in the figure). In some cases, a plurality of (three in the figure) vertical members 30 are provided with a rectangular fence component. Then, the heights of these fence constituent parts are sequentially raised and lowered in accordance with the inclination angle, and the vertical members 30 arranged adjacent to each other are connected by the transverse beam 10.

  In this case, in order to attach importance to the landscape, the height of the horizontal beam 10 is also adjusted, and the horizontal beam 10 for constructing each fence component can be extended to function as a connecting horizontal beam 10. it can. Moreover, it is also possible to connect the adjacent vertical members 30 using the connection-dedicated beam 60. In any case, the longitudinal member 30 is preferably provided with engaging grooves 31a... At a plurality of positions so that the transverse beam 10 or the exclusive connection beam 60 can be connected at an appropriate position.

  Next, 2nd embodiment concerning a wooden fence is described. In this embodiment, the longitudinal member abutting portion in the first embodiment is configured in a substantially arc shape. In the present embodiment, as shown in FIG. 11, the longitudinal member 130 to be supported is an example in which a columnar member (log) having a circular cross section is used, and the transverse beam constituting member used in the present embodiment. 140 and 150 are formed with substantially arc-shaped contact portions 143, 144, 153, and 154 to contact the surface of the longitudinal member 130 having the above shape. Here, among the arc-shaped contact portions 143, 144, 153, and 154, the deepest portions 143c and 153c are linearly edged, and this constitutes a locking piece portion. .

  In addition, engagement grooves 131a, 132a, 131b, and 131b are provided on the surface of the vertical member 130 supported by the transverse beam constituting members 140 and 150 having the above-described configuration. The insertion piece portions 143c and 153c can be engaged.

  Due to the above-described configuration, as shown in FIG. 12, the longitudinal member 130 having a circular cross section has the side where the engaging grooves 131a and 131b are provided facing the transverse beam constituting members 140 and 150, and the transverse member from both sides. They are connected by being sandwiched between the beam constituent members 140 and 150. The vertical member abutting portions 143 and 153 of the transverse beam constituting members 140 and 150 are engaged with the engaging members 131a and 131b of the vertical members while the engaging piece portions 143c and 153c are engaged with the other portions 143a and 153a. 143b, 153a, and 153b come into contact with the surface of the longitudinal member 130, and can exert a positioning effect that restricts the movement of the longitudinal member 130. Further, since the engaging grooves 131a and 131b and the engaging piece portions 143c and 153c of the vertical member 13 are both linearly provided, the locking piece portions 143c and 153c are engaged with the engaging grooves 131a and 131b. In (see FIG. 12B), both the straight portions are brought into contact with each other to prevent the vertical member 130 from rotating around the axis.

  Further, in the third embodiment, as shown in FIG. 13, like the longitudinal member 230, there is a structure in which the support column 220 is connected by the same transverse beam constituting members 240 and 250. This embodiment uses a long transverse beam in situations such as when a support column 220 is provided in the middle of a long span support column 20 (FIG. 1) or when a support column 220 is provided in the middle of an inclined surface. The support 220 and the vertical member 230 are simultaneously connected to each other to simplify the support structure of the transverse beam.

  In the present embodiment, in the support column 220, the engaging grooves 221a, 222a, 221b, and 222b are configured similarly to the longitudinal member 230 so that the longitudinal member abutting portions 243 and 253 of the transverse beam constituting members 240 and 250 can be engaged. It has become. Then, by the engagement of the vertical member abutting portions 243 and 253, the horizontal beam constituting members 240 and 250 are supported by the support column 220. In this case, in the vicinity where the support column 220 is connected, the connection between the lateral beam constituting members 240 and 250 is reinforced by the through bolt 211 and the nut 212, so that the connection can be firmly connected.

  Furthermore, regarding the connection with the support | pillar, as shown in FIG. 14, using the transverse beam structural member 40,50 used for 1st embodiment, the basic support | pillar 20 and the said transverse beam structural member 40,50 are used. Can also be linked. In this connection method, the positional relationship between one transverse beam constituting member 40 and the other transverse beam constituting member 50 is relatively moved in the lateral direction by one pitch of the longitudinal member abutting portion. Then, the column 20 is clamped from both sides by the horizontal beam constituting members 40 and 50 with the column 20 at the center, and the whole is fastened by the through bolts 11. Here, since the fastening of the through bolt 11 in the support column 20 does not connect the continuous transverse beam constituent members, the through bolts 11a are similarly applied to the vertical members 30a and 30b arranged on both sides of the support column 20. , 11b. According to this method, the horizontal beam 10 can be connected to the support column 20 without using the connection fitting between the support column 20 and the horizontal beam constituting members 40 and 50.

  While typical embodiments have been described above, various forms can be employed without departing from the spirit of the present invention. For example, the transverse beam constituting member may be a rod-like transverse beam constituting member without being formed into a plate shape. In this case, as shown in FIG. 15, it is possible to provide a configuration in which a vertical material abutting portion 343 is provided on the surface that contacts the vertical material 330 and an engaging piece 323 c is provided in a part thereof. In addition, when comprising the horizontal beam structural member 340 of such a structure, the whole member can be comprised with a timber (thinned material), and only the latching piece 343c is comprised with a metal plate-shaped member. Can do. The metal engaging piece 343 c can be protruded from the vertical member 330 by being inserted from the back surface of the transverse beam constituting member 340. Further, in order to hook the vertical member 330 by the engaging piece 343c, the vertical member 330 is provided with engaging grooves 331a and 331b.

  Further, the transverse beam constituting member may be formed in a rod shape with a synthetic resin or the like. Even in this case, the vertical member abutting portion 343 may be provided in the same manner as described above, but the vertical member abutting portion 343 may not be provided. In this case, as shown in FIG. 16, at least one arbitrary surface 443, 453 can be used as a surface for contacting a vertical member, and a plurality of protrusions 445, 455 can be provided on the surface 443, 453. According to such a configuration, the projections 445 and 455 of the longitudinal member abutting surfaces 443 and 453 are formed on the surface of the longitudinal member 430 by sandwiching the longitudinal member constituent members 440 and 450 from both sides with the wooden longitudinal member 430 as the center. This means that the vertical member 430 can be fixed. And when setting it as such a structure, an engaging groove is not provided in the vertical member 430, but it will be supported by the horizontal beam structural members 440 and 450 in arbitrary positions. Note that the fixing by clamping as described above can be performed not only by providing the protrusions 445 and 455 on the vertical material contact surfaces 443 and 453 but also by a surface treatment for increasing the frictional resistance of the surface.

  On the other hand, when the transverse beam constituting member is constituted by a plate-like member, as shown in FIG. 17, in the substantially rectangular metal plate material 70, this is conceptually divided into three sections, the central constituting portion 71, A horizontal beam constituting member having a U-shaped cross-section can be formed by bending along each boundary line. In the case of such a configuration, the vertical member contact constituent parts 74 and 75 that are notched in advance are provided at the edges of the upper and lower side constituent parts 72 and 73 of the plate-like member 70.
