Description

[Technical Field]

[0001] The present invention relates to a connecting structure for furring strips used in fences and the like. [Background technology]

[0002] Generally, fences installed along property boundaries are constructed by hanging multiple furring strips made of angle bars or similar between posts erected in the ground at specified intervals, and then stretching a net over the furring strips. Also, if the total length of a single furring strip is shorter than the installed length of the fence, the fence is constructed by connecting multiple furring strips lengthwise.

[0003] Various conventional furring strip connection structures are known. For example, as shown in Figure 10, the end faces of two adjacent furring strips are butted together and connected by tightening multiple bolts and nuts via a joint piece with a side that is shorter than the side of the furring strip.

[0004] Patent document 1 also describes a structure in which one end of a furring strip is recessed inward by the thickness of the plate to form a drawn portion, and the other end of the other furring strip is overlapped on this drawn portion and fastened together with bolts.

[0005] According to such a furring strip connecting structure, the furring strip connecting structure can be simplified, which has the economic effect of reducing manufacturing costs and providing a fence at low cost. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Japanese Utility Model Application Publication No. 49-139833 Summary of the Invention [Problem to be solved by the invention]

[0007] However, in conventional furring strip connection structures, adjacent furring strips are fastened with bolts using joint fittings, which increases the number of parts and makes assembly work complicated. Also, as described in Patent Document 1, the main posts and furring strips are attached to each other using fasteners, but with a structure that connects furring strips with joint fittings, there is also the problem that joint fittings cannot be used at the attachment positions of the main posts and furring strips.

[0008] Therefore, the present invention has been made in consideration of the above problems, and aims to provide a furring strip connecting structure that reduces the number of parts, simplifies assembly work, and allows furring strips to be connected at the main pillar position. [Means for solving the problem]

[0009] The furring strip connection structure of the present invention is a furring strip connection structure that connects a first furring strip having horizontal and vertical sides extending along the longitudinal direction and a second furring strip having horizontal and vertical sides extending along the longitudinal direction along the longitudinal direction, and includes an overlapping portion where one end of the first furring strip and the other end of the second furring strip overlap, and fasteners that clamp the horizontal sides of the first furring strip and the second furring strip at the overlapping portion or the vertical sides of the first furring strip and the second furring strip from the width direction of the first furring strip or the second furring strip, and the fasteners are attached to main posts extending in the vertical direction. The fastener has a bolt insertion portion through which a bolt to be inserted into the main column can be inserted, and a notch portion through which the overlapping portion can be inserted, and the notch portion is configured as a stepped groove having a first step and a second step, the first step has a groove width through which one piece of the horizontal side or the vertical side can be inserted, and the second step has a groove width through which two pieces of the horizontal side or the vertical side can be inserted. It is characterized by the following.

[0010] In the furring strip connecting structure of the present invention, it is preferable that the horizontal edge and the vertical edge are recessed inward at one end of at least one of the first furring strip or the second furring strip, and a narrowed portion is formed consisting of a horizontal plane approximately parallel to the horizontal edge and a vertical plane approximately parallel to the vertical edge.

[0013] In the furring strip connecting structure according to the present invention, it is preferable that the drawn portion has a fastener engaging portion formed by cutting out the horizontal surface or the vertical surface in the width direction.

[0014] The above summary of the invention does not list all of the features necessary for the present invention, and subcombinations of these features may also constitute inventions. [Effects of the Invention]

[0015] The furring strip connecting structure of the present invention allows the furring strips to be connected and attached to the main posts simultaneously, which reduces the number of parts, reduces manufacturing costs, and simplifies assembly work. In addition, the furring strips can be connected to the main posts at the same time. [Brief explanation of the drawings]

[0017] Preferred embodiments for carrying out the present invention will be described below with reference to the drawings. Note that the following embodiments do not limit the inventions according to the claims, and not all of the combinations of features described in the embodiments are necessarily essential to the solution of the invention.

[0019] In this specification, the leading end and trailing end in the longitudinal direction are defined as the directions of the arrows shown in Fig. 3. In addition, in this specification, the height direction, width direction, and inside and outside of the fence furring strip are defined as the directions of the arrows shown in Fig. 3.

[0020] As shown in Figure 1, the furring strips 1 used in the furring strip connecting structure of this embodiment are installed between posts 2 erected at intervals on the ground at a height that will form the upper and lower edges of the fence 100, and a net 3 is attached.

[0021] As shown in Figure 1, the posts 2 have main posts 2a with a generally V-shaped cross section and nets 3 on both sides of the post, and end posts 2b with a generally L-shaped cross section and nets 3 on one side of the post. Both the main posts 2a and end posts 2b are preferably made of general structural rolled steel or the like. Furthermore, the main posts 2a and end posts 2b have through holes for passing bolts at the heights that correspond to the upper and lower edges of the fence 100, and the furring strips 1 are attached to the posts 2 with bolts that pass through the through holes and fasteners, which will be described later.

[0022] The net 3 is a member made of multiple iron wires, and is preferably a wire mesh made by processing the iron wires into a series of mountains and weaving them together to form a diamond-shaped mesh. The net 3 is not fixed by welding or other means at the joints of the multiple iron wires, so the net 3 itself is flexible and has shock absorption properties. The net 3 is attached by hooking it onto the net claws 16, which will be described later and are formed on the furring strips 1.

[0023] As shown in Figure 2, the furring strip connection structure of this embodiment is a furring strip connection structure that connects a first furring strip 1a having a horizontal side 10a and a vertical side 20a extending along the longitudinal direction, and a second furring strip 1b having a horizontal side 10b and a vertical side 20b extending along the longitudinal direction, along the longitudinal direction, and has an overlapping portion where one end of the first furring strip 1a and the other end of the second furring strip 1b are overlapped, and a fastener 40 that clamps the horizontal sides 10a, 10b of the first furring strip 1a and the second furring strip 1b of the overlapping portion 30 from the width direction of the first furring strip 1a and the second furring strip 1b, and the fastener 40 is attached to the main pillar 2a via a bolt 50.

[0024] As shown in Figure 1, furring strips 1 form the upper and lower edges of fence 100 by longitudinally connecting the tip end (one end in the claims) of first furring strip 1a, which is an adjacent fence furring strip, with the base end (the other end in the claims) of second furring strip 1b. The first furring strip 1a and second furring strip 1b that form furring strip 1 are both members of the same shape, and it is preferable to use angle irons with an L-shaped cross section having horizontal sides 10a, 10b and vertical sides 20a, 20b, as shown in Figure 3.

[0025] The first furring strips 1a and second furring strips 1b are made of thick general structural rolled steel or the like, and are preferably zinc-plated or electrostatically powder coated with a polyester resin base paint to prevent corrosion due to rust, etc. In this specification, the horizontally positioned sides of the first furring strips 1a and second furring strips 1b are referred to as horizontal sides 10a, 10b, and the vertically positioned sides are referred to as vertical sides 20a, 20b, depending on the mounting orientation to the fence 100.

[0026] At the tip of the first furring strip 1a, the horizontal side 10a and the vertical side 20a are recessed inward, and a drawn portion 12 is formed, which consists of a horizontal surface 13 that is approximately parallel to the horizontal side 10a and a vertical surface 14 that is approximately parallel to the vertical side 20a. The outer surface of the drawn portion 12 and the outer surfaces of the horizontal side 10a and the vertical side 20a that are not recessed inward are smoothly connected by a tapered portion 11. In addition, the drawn portion 12 is formed with a fastener locking portion 15, which is formed by cutting out the horizontal surface 13 of the drawn portion 12 in the width direction.

[0027] When the first furring strip 1a and the second furring strip 1b are connected, the outer surface of the drawn portion 12 abuts against the inner surface of the base end of the second furring strip 1b. In this way, the base end of the second furring strip 1b abuts against the outer surface of the drawn portion 12, so that when the first furring strip 1a and the second furring strip 1b are connected, the horizontal edges 10a, 10b and the vertical edges 20a, 20b can be made approximately flush with each other. This maintains the straightness of the furring strip 1 after connection and does not impair the aesthetic appearance. Therefore, it is preferable that the outer surface of the drawn portion 12 be recessed inward by the plate thickness from the outer surfaces of the horizontal edges 10a and the vertical edges 20a.

[0028] In addition, a plurality of net claws 16 protruding inward in the width direction are formed at regular intervals on the vertical edge 20a of the first furring strip 1a and the vertical edge 20b of the second furring strip 1b. The net claws 16 are preferably formed by shearing a portion of the vertical edges 20a, 20b by press working, for example, and plastically deforming them.

[0029] By providing a plurality of such net claw portions 16 along the entire length of the furring strip 1, the net 3 can be fixed at the top and bottom of the fence 100.

[0030] In this embodiment, the net claw portion 16 is formed by shearing a portion of the vertical edges 20a, 20b by press processing and plastically deforming it, but the method of forming the net claw portion 16 is not limited to this, and it may also be formed from a material equivalent to that of the first furring strip 1a and the second furring strip 1b and attached to the vertical edges 20a, 20b by welding.

[0031] As shown in Fig. 4, the fastener 40 has a pair of legs 41, 41 and a curved portion 42 that connects one end of the legs 41 in an arc shape, and is a member formed by bending a flat plate of a specified thickness into a substantially U-shape along the width direction of the furring strip 1. The curved portion 42 and the upper portion of the pair of legs 41 form a bolt insertion portion 43 into which a bolt 50, described below, can be inserted. In addition, the leg 41 is formed with a notch 44 that extends along the width direction.

[0032] As shown in FIG. 5 , the notch 44 is configured as a stepped groove having a first step 45 extending in the width direction and a second step 46 formed continuously with the first step 45. The groove width G1 of the first step 45 is a groove width that allows one horizontal edge 10a, 10b or one vertical edge 20a, 20b of the furring strip 1 to be inserted therethrough, and is formed slightly larger than the thickness of the furring strip 1. The groove width G2 of the second step 46 is a groove width that allows one overlapping portion 30 formed by overlapping the horizontal edges 10a, 10b or the vertical edges 20a, 20b of the furring strip 1 to be inserted therethrough, and is formed slightly larger than twice the thickness of the furring strip 1. A step portion 47 is formed at the continuous portion of the first step 45 and the second step 46.

[0033] Next, the assembly procedure for the furring strip connecting structure according to this embodiment will be described with reference to Figures 6 to 9. As shown in Figure 6, the inner surface of the base end portion 4 of the first furring strip 1a is brought into contact with the outer surface of the drawn portion 12 of the second furring strip 1b, forming an overlapping portion 30 where the horizontal side 10a of the first furring strip 1a and the horizontal surface 13 of the drawn portion 12 overlap.

[0034] As shown in Figure 7, the fastener 40 is inserted into the overlapping portion 30 along the width direction of the furring strip 1 and fastened to the main column 2a with a bolt 50. At this time, the bolt 50 is inserted into the bolt insertion portion 43 of the fastener 40 and threaded into a nut 51 locked to the end portion 48 of the fastener 40. The fastener 40 is attached so that its outer surface fits into the fastener locking portion 15 formed in the tapered portion 12. The fastener 40 is restrained in the longitudinal direction of the furring strip 1 by engaging with the fastener locking portion 15, and is restrained in the width direction by tightening the bolt 50 and nut 51, fixing its position.

[0035] 8, the overlapping portion 30 of the furring strip 1 is inserted into the cutout portion 44 of the fastener 40, with the horizontal edge 10a of the first furring strip 1a being inserted into the first step 45 of the cutout portion 44 and the horizontal edge 10b of the second furring strip 1b being inserted into the second step 46 of the cutout portion 44. The fastener locking portion 15 formed on the horizontal edge 10b of the second furring strip 1b abuts against the step portion 47 formed in the cutout portion 44 of the fastener 40.

[0036] In addition, the fastener 40 can also be used to fasten the furring strip 1 to the main pillar 2a at a point other than the connecting portion of the furring strip 1. In this case, as shown in Figure 9, the horizontal edge 10a can be inserted into the first step 45 of the cutout portion 44 of the fastener 40 to fix the furring strip 1 to the main pillar 2a.

[0037] As described above, according to the furring strip connecting structure of this embodiment, a tapered portion 12 is formed at the tip of the second furring strip 1b, and the base end portion 4 of the second furring strip 1b is overlapped on this tapered portion 12 to form the overlapping portion 30. The fasteners 40 that clamp the overlapping portion 30 are then fixed to the main pillar 2a, thereby connecting the furring strips. Since the furring strips can be connected and fixed to the main pillar with a single bolt, the number of parts such as joint pieces, bolts, and nuts that were previously required when connecting furring strips can be reduced, thereby reducing manufacturing costs and making it possible to easily connect the first furring strip 1a and the second furring strip 1b.

[0038] In the above embodiment, the case where the drawn portion 12 is formed in the second furring strip 1b has been described, but it is also possible to form an overlapping portion by overlapping the base end of the first furring strip and the tip end of the second furring strip without forming the drawn portion 12. Furthermore, in the above embodiment, the tapered portion 11 is formed so as to be inclined with respect to the horizontal sides 10a, 10b and the vertical sides 20a, 20b, and is connected to the drawn portion 12. However, the tapered portion 11 may be formed in a stepped shape that is perpendicular to the horizontal sides 10a, 10b and the vertical sides 20a, 20b. It is clear from the claims that such modified or improved embodiments are also within the technical scope of the present invention. [Explanation of symbols]
