Description

[Technical Field]

[0001] The present invention relates to a foundation that is placed on the ground to secure fence posts. [Background technology]

[0002] BACKGROUND ART Conventionally, fences that separate the inside and outside of a designated area such as a detached house, an apartment building, or a public facility have been installed by attaching posts to foundations buried in the ground.

[0003] Since the foundations of such fences are buried in the ground, they cannot be easily removed. Therefore, when installing a temporary fence that requires removal, a foundation placed on the ground may be used.

[0004] Various types of such spread footings are known, for example the spread footing described in Patent Document 1. The spread footing described in Patent Document 1 has a fence mounting post where the fence panel is attached, and a foundation support post that is embedded in the spread footing, which are provided separately, and has brackets that connect the fence mounting post and the foundation support post to each other.

[0005] With such a foundation, the fence panel can be placed on the surface of the foundation or in front of the foundation, eliminating any protruding parts of the foundation and improving safety. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Japanese Patent Application Laid-Open No. 2004-84446 Summary of the Invention [Problem to be solved by the invention]

[0007] However, conventional foundations have the problem of requiring more parts than conventional foundations that are buried in the ground because the foundation support posts and the fence panel mounting posts are connected by brackets. Furthermore, conventional foundations have the potential to collapse due to external impacts such as strong winds or collisions, and there has been a demand for ways to prevent this.

[0008] Therefore, the present invention was made in consideration of the above problems, and aims to provide a foundation that can reduce the number of parts compared to conventional foundations and can prevent the installed fence from easily collapsing. [Means for solving the problem]

[0009] The base foundation according to the present invention is a base foundation that is placed on the ground and to which fence posts can be attached, and includes a base foundation body having a generally rectangular parallelepiped shape, and a post attachment member that is attached along the height direction of the base foundation body through an attachment hole formed on a side surface of the base foundation body. The support column mounting member is an angle iron having a first surface facing the side surface of the base body and a second surface to which the support column is attached. It is characterized by the following.

[0010] The base of the present invention is a base that is placed on the ground and to which fence posts can be attached, and comprises a base body that is roughly rectangular, and a post attachment member that is attached along the height direction of the base body via attachment holes formed on the side of the base body, the attachment holes forming a row of attachment holes formed at least along the vertical direction of the side of the base body, and the rows of attachment holes are formed in at least two rows along the left and right side edges of the side.

[0011] In addition, in the base according to the present invention, it is preferable that the base body is provided with a means for preventing tipping over.

[0012] In addition, in the base of the present invention, it is preferable that the anti-tip means is a plate-like member extending from the bottom surface of the base body along the ground.

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

[0015] The base of the present invention comprises a base body having an approximately rectangular parallelepiped shape and a support mounting member attached along the height direction of the base body via a mounting hole formed on the side of the base body, thereby reducing the need for parts such as arm brackets that were previously used, and since the base body comprises a support mounting member attached via a mounting hole formed on the side of the base body, a fence can be installed without the need for members to seal the gaps between the bases.

[0016] Furthermore, since the base body is provided with a means for preventing tipping over, it is possible to prevent the fence from easily collapsing due to strong winds or external impacts. [Brief explanation of the drawings]

[0018] 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] FIG. 1 is a front view of a fence using a base according to an embodiment of the present invention, FIG. 2 is an oblique view of the base according to an embodiment of the present invention, FIG. 3 is an enlarged view of part A in FIG. 1, and FIG. 4 is a plan view for explaining the installation state of the base according to an embodiment of the present invention.

[0020] As shown in Figure 1, the base 10 of this embodiment is placed on the ground G at a predetermined interval, and is equipped with posts 1 to which a fence 3 that separates the inside and outside of a predetermined area such as a detached house, apartment building, or public facility and a gate 4 that can be opened and closed freely and allows passage inside and outside the fence 3 are attached.

[0021] The support posts 1 include an end post adjacent to the gate 4 at the end of the fence 3 and a main post arranged along the installation direction of the fence 3; the main post is a steel material with an approximately V-shaped cross section, and has mounting holes for attaching the furring strips 6, as well as a flange portion that extends along the extension direction of the fence 3; the end posts are preferably made of angle steel with an L-shaped cross section, and have mounting holes for attaching the furring strips 6, just like the main posts.

[0022] The gate 4 is attached so as to be able to open and close freely via hinges 5 attached along the axial direction of the support posts 1. The gate 4 is also attached so as to be able to engage with a locking fixture (not shown) attached to the other support post 1, and by engaging a catch with the locking fixture, the gate 4 can be prevented from opening or closing and can be fixed in a closed state.

[0023] The fence 3 has a pair of upper and lower furring strips 6 attached to posts 1 generally parallel to each other and facing the ground G, with a wire mesh net 7 attached between the furring strips 6. The furring strips 6 are preferably made of angle iron members with an L-shaped cross section, and are constructed by connecting multiple angle iron members using connecting fittings (not shown) as appropriate depending on the installation length of the fence 3. In addition, as shown in Figure 3, they are formed with claws 8 for engaging with the net 7, which will be described later.

[0024] The net 7 is preferably formed in the form of a diamond-shaped wire netting, tortoiseshell wire netting, mesh (grid-like), or the like, which is made by weaving together coated wires, each of which has a core wire covered with a synthetic resin or the like, at a predetermined mesh size. Alternatively, the net 7 may be formed in the form of a fence, with multiple vertical and horizontal metal wires arranged parallel to each other and crossing each other.

[0025] As shown in Figure 2, the base 10 of this embodiment comprises a base body 11 having an approximately rectangular parallelepiped shape and a support column mounting member 13 attached along the height direction of the base body 11 via a mounting hole 12 formed in a side surface 17 of the base body 11.

[0026] The base body 11 is preferably made of concrete, and reinforcing bars may be placed inside the concrete as needed. Weights may be attached to the base body 11 to ensure gravity, and weight mass attachment means for attaching the weights may be formed separately.

[0027] The base body 11 has a plurality of mounting holes 12 formed in the side surface 17, and the mounting holes 12 form a plurality of mounting hole rows L formed along the vertical direction. In the base body 10 according to this embodiment, three mounting hole rows L are formed: mounting hole rows L1 and L3 formed along the left and right side edges of the base body 11, respectively, and mounting hole row L2 formed along approximately the center of the base body 11. As shown in FIG. 4, grip anchors are embedded in the mounting holes 12, and are formed so that support mounting members 13 can be fastened thereto using bolts, which will be described later.

[0028] The pillar mounting member 13 is a member made of angle iron and has a first surface 14 facing the side surface 17 of the base body 11 and a second surface 15 to which the pillar 1 is attached. As shown in Fig. 2, the pillar mounting member 13 is attached along the height direction of the base body 11, and is preferably positioned at a predetermined height (for example, approximately 100 mm from the ground G) from the ground G. Mounting holes 19 are formed on the first surface 14 and the second surface 15 at positions corresponding to the mounting holes 12 of the base body 11 and the mounting holes of the pillar 1.

[0029] In addition, tip-over prevention means 16 is formed at the lower end of the base body 11. The tip-over prevention means 16 is preferably a plate-like member that extends from the bottom surface of the base body 11 along the ground G and is arranged so as to protrude outward from the side surface 17. The extending direction of the tip-over prevention means 16 can be set appropriately depending on the direction in which the base body 10 according to this embodiment may tip over.

[0030] Next, a method for installing the base 10 according to this embodiment will be described. As shown in Fig. 3, the base 10 according to this embodiment is attached to a support 1 serving as an end post adjacent to the gate 4, for example. First, as shown in Fig. 4, the base 10 according to this embodiment has a support mounting member 13 attached to a mounting hole row L3 along the side edge of the base body 11 on the gate 4 side. At this time, the second surface 15 of the support mounting member 13 is positioned so as to face the gate 4.

[0031] Then, mounting holes 19 formed in second surface 15 are fastened to mounting holes 20 in posts 1 with bolts and nuts 18. In this way, in base 10 according to this embodiment, posts are attached to support mounting members 13 provided on the side of base body 11, so that fence 3 can be installed without creating a gap between the bottom end of fence 3 and the ground G.

[0032] Similarly, the support post 1 on the opposite side of the gate 4 can be attached by attaching the support post mounting member 13 to the mounting hole row L1. When attaching the main post, the mounting hole row L2 or the like can be used to fix the main post to the base using the support post mounting member.

[0033] In this way, the row of mounting holes can be selected appropriately depending on the position of the support to be mounted, so the base 10 of this embodiment can be adapted to various mounting positions, contributing to cost reduction without increasing the variety of base 10.

[0034] In addition, the base 10 of this embodiment is provided with a plate-shaped anti-tip means 16 on the bottom surface of the base body 11, thereby preventing the fence 3 from easily collapsing due to strong winds or external impacts.

[0035] In the above embodiment, the gate 4 is configured as a single swing gate, but a pair of gates 4 may be provided to configure a double swing gate. It is clear from the claims that such modified or improved embodiments are also included within the technical scope of the present invention. [Explanation of symbols]
