Description

[Technical field]

[0001] The present invention relates to a brace member that can be adjustably attached to a frame body after width adjustment of the frame body of a prefabricated gate, fence, or the like. [Background technology]

[0002] Conventionally, prefabricated gates and fences having a frame body are known, as shown in Fig. 7. A prefabricated gate 100 is attached between posts 5 erected on a foundation 6 so as to be freely opened and closed, and is fitted with a frame body 2 consisting of a pair of vertical frames and a pair of horizontal frames made of angle iron 3, a panel body 4 consisting of a wire mesh or the like assembled within the frame body 2, and a brace member 20 attached diagonally to reinforce the frame body 2. Such prefabricated gates and fences are assembled in advance in a factory or the like and then brought to the construction site and installed. A known form of brace member is a pair of brace bodies connected by a turnbuckle.

[0003] However, when assembling gates or fences in advance at a factory, the spacing between the posts may vary depending on the conditions at the construction site when pre-assembled products are brought in and installed at the construction site, and adjustments such as narrowing the width may be necessary to accommodate this.

[0004] Various methods for narrowing the width are known. For example, as described in Patent Document 1, a gate is known that can easily expand or contract the distance between a pair of locking sources attached to the rotating gate to match the front-to-rear width of the fixed gatepost and gate when locking the gate.

[0005] With this type of gate, there is no need to create separate locking pieces that correspond to the fixed gate post and the front-to-rear width of the gate, and adjustments can be made according to the spacing between the posts while reducing the number of parts.

[0006] Also, as described in Patent Document 2, a gate panel is known which comprises a frame body formed by left and right vertical frames and upper and lower horizontal frames, and a panel body attached to the frame body, the frame body having grooves into which the width ends of the panel body are inserted along the longitudinal direction, the width dimension of the horizontal frame being longer than the width dimension of the panel body, and the difference between the width dimension of the panel body and the lateral movable width that can be assumed when both side ends of the panel body are inserted into the grooves is greater than the difference between the width dimension of the horizontal frame and the movable width.

[0007] With such a gate panel, even if one of the vertical frames is removed and the horizontal frame and the panel body are cut flush at a specified position during the work of shortening the width of the gate panel, the vertical frame can be reattached and the gate panel can be assembled without any problems.

[0009] However, the conventional width shortening method uses ready-made products, so there is a problem that the width shortening adjustment range is small and it is not possible to flexibly adjust the width according to the conditions at the construction site. Also, when the width of the frame body is adjusted, the diagonal length of the frame body also changes, so in order to accommodate this change, the length of the brace member is adjusted by adjusting the tightening of the turnbuckle, but this adjustment method has a problem of a small adjustment range.

[0010] Therefore, the present invention has been made in consideration of the above problems, and has an object to provide a brace member whose length can be adjusted to match the diagonal length of the frame body after adjusting the width dimension of the frame body, such as a gate or a fence. [Means for solving the problem]

Multiple A cutting groove is formed. The plurality of cutting grooves constitute a length adjusting means. It is characterized by the above.

[0012] In the brace member according to the present invention, it is preferable that the cutting groove is a tool guide groove that guides a tool for cutting the shuttlecock portion.

[0013] In the brace member according to the present invention, it is preferable that a pair of the brace bodies are provided corresponding to the corner portions and connected by the turnbuckle.

[0014] In the brace member according to the present invention, the frame body is a frame body for a gate, and it is preferable that the brace member be attached to a corner portion of the frame body.

[0015] The above summary of the invention does not list all of the necessary features of the present invention, and any subcombination of these features may also constitute an invention. Effect of the Invention

[0016] The brace member of the present invention has a cutting groove in the shuttlecock portion, so that the length of the brace member can be adjusted by cutting the shuttlecock portion along the cutting groove, and a large adjustment range can be ensured. [Brief description 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 all of the combinations of features described in the embodiments are not necessarily essential to the solution of the invention.

[0019] FIG. 1 is an oblique view of a prefabricated gate whose width has been adjusted using a brace member according to an embodiment of the present invention, FIG. 2 is a front view of the brace member according to an embodiment of the present invention, FIG. 3 is a front view of the brace body of the brace member according to an embodiment of the present invention, FIG. 4 is an enlarged view showing the frame body in a width-adjusted state, FIG. 5 is an enlarged view showing the state of the connecting parts in a width-adjusted state, and FIG. 6 is a process diagram for explaining the width adjustment method using the brace member according to an embodiment of the present invention.

[0020] As shown in Figure 1, the prefabricated gate 1 of this embodiment has posts 5 fixed to a foundation 6 poured into the ground, which are arranged at predetermined intervals, and a gate 40 is attached between the posts 5 so as to be able to be opened and closed freely.

[0021] The gate 40 is attached so as to be freely opened and closed via hinges 41 attached along the axial direction of the support pillars 5. The gate 40 also has a frame body 2 having a pair of vertical and horizontal frames made of angle iron 3, a gate main body 4 attached within the frame body 2, and a pair of brace members 20 arranged on a diagonal line of the frame body 2. The mutually intersecting vertical and horizontal frames of the frame body 2 are welded so as to be approximately perpendicular to each other.

[0022] The angle iron 3 is a steel material with an L-shaped cross section, and has an upper side 3a and a lower side 3b that intersect approximately perpendicularly as shown in Fig. 4. The gate body 4 can be made of various materials such as wire netting, mesh material, and porous material, and can be appropriately selected taking into consideration wind resistance and durability.

[0023] 1, the gate 40 has a reinforcing plate 7 that is disposed approximately parallel to the ground so as to connect the vertical frames together. The reinforcing plate 7 is also provided with a handle 8 that serves as an operating part for opening and closing the gate 40, and a latch 9 that is movable along the extension direction of the reinforcing plate 7 is attached thereto, and the gate 40 and the pillar 5 can be connected and locked by moving the latch 9 toward the pillar 5.

[0024] The horizontal frames and reinforcing plates 7 of the frame body 2 are cut to match the spacing of the support posts 5, and the cut portions are connected by connecting members 10, 30. As shown in Fig. 4, the connecting member 10 that connects the cut horizontal frames, that is, the angle irons 3, includes a clamping portion 11 that clamps the horizontally extending upper side 3a of the angle irons 3 in the vertical direction, and a reinforcing portion 12 that extends from one end of the clamping portion 11 along the lower side 3b of the angle irons 3, and is connected by a connecting means 13 so as to penetrate the clamping portion 11. The connecting means 13 can have various configurations as long as it can attach the connecting member 10 to the frame body 2, but it is preferable to use, for example, a bolt and a nut.

[0025] 5, the joint members 30 for the reinforcing plates 7 are plates capable of connecting the reinforcing plates 7 cut to fit the spacing between the posts 5, and are attached in pairs at a predetermined spacing in the vertical direction corresponding to a pair of reinforcing plates 7. The joint members 30 are attached using any number of mounting bolts 31.

[0026] Although the joining members 30 are attached in pairs at a predetermined interval to correspond to the reinforcing plates 7 so as not to interfere with the movement of the yoke 9, they may be configured as a single plate that serially connects the pair of reinforcing plates 7 if they are attached at positions that do not interfere with the movement of the yoke 9. By configuring the joining member 30 as a single plate that serially connects the pair of reinforcing plates 7 in this way, the rigidity of the joining member 30 can be improved.

[0027] As shown in FIG. 2, the brace member 20 according to this embodiment is a rod-shaped member in which a pair of brace bodies 21, 21 are screwed together with a turnbuckle 22.

[0028] As shown in Fig. 3, the brace body 21 has a flat shuttlecock portion 23 and an extension portion 24 that extends from one end of the shuttlecock portion 23 and has a screw portion 25 formed at its tip. A plurality of mounting holes 26 are formed at predetermined intervals in the shuttlecock portion 23 along the extension direction. The intervals between the mounting holes 26 are preferably about 50 to 100 mm, for example, and preferably about 70 to 90 mm.

[0029] Further, a cutting groove 27 extending in the width direction of the shuttlecock portion 23 is formed between adjacent mounting holes 26. The cutting groove 27 is used as a cutting guide when adjusting the length of the brace body 21 by cutting the shuttlecock portion 23. At this time, it is preferable that the cutting groove 27 functions as a tool guide groove that guides the blade of a cutting tool, and the groove depth of the cutting groove 27 is formed to an extent that the rigidity of the brace body 21 can be ensured. Specifically, it is preferable that the groove depth of the cutting groove 27 is formed to be ⅓ or less of the plate thickness of the shuttlecock portion 23.

[0030] The turnbuckle 22 is screwed to the screw portion 25 at the tip of the extension portion 24. The turnbuckle 22 has female threads 22a at both ends in the longitudinal direction into which the screw portion 25 can be screwed, and connects the pair of brace bodies 21 together.

[0031] Next, a method for adjusting the width of the gate 40 using the brace member 20 according to this embodiment will be described with reference to FIG.

[0032] The method for adjusting the width of the gate 40 using the brace member 20 of this embodiment includes a frame cutting process (S101), a gate main body cutting process (S102), a frame joining process (S103) and a joining process (S105) consisting of a reinforcing plate joining process (S104), a gate main body installation process (S106), and a brace member adjustment process (S107).

[0033] In the frame cutting process (S101), the horizontal frame of the frame body 2 is cut to match the spacing of the posts 5. At this time, if the length of the horizontal frame of the frame body 2 prepared in advance is longer than the spacing of the posts 5, the angle irons 3 after cutting are cut to match the length of the posts 5, but if the length is shorter than the spacing of the posts 5, an extension material of a specified length is prepared after cutting, making it possible to shorten or extend the frame body 2 in the width direction.

[0034] In the gate body cutting process (S102), the width of the gate body 4 is cut to match the spacing between the posts 5. Next, in the joining process (S105), the frame body 2 and the gate body 4 cut in the frame body cutting process (S101) and the gate body cutting process (S102) are joined together.

[0035] In the frame joining step (S103), the angle irons 3 of the cut horizontal frame portions are butted against each other, the clamping portions 11 of the joining members 10 are assembled to the butted portions, and the joining means 13 is fastened to the through holes 14 to adjust the width of the frame body 2 to match the spacing of the posts 5. If the length of the angle irons 3 is shorter than the spacing of the posts 5, the angle irons 3 after cutting may be joined to the extension members by the joining members 10. The frame body 2 is joined using the joining members 10 on both the upper and lower horizontal frames, but the joining members 10 assembled to the upper and lower sides can be shared by assembling them upside down.

[0036] In the reinforcing plate joining step (S104), the cut reinforcing plates 7 are butted together and joined together by the joining members 30. When the length of the reinforcing plate 7 is shorter than the interval between the posts 5, the cut reinforcing plate 7 and the extension member may be joined by the joining members 30.

[0037] In the gate body assembly process (S106), the gate body 4 cut in the gate body cutting process (S102) is assembled to the frame body 2 assembled according to the spacing of the posts 5. The gate body 4 may be attached to the frame body 2 using conventionally known mounting hardware, or the gate body 4 may be attached to the frame body 2 by welding or the like.

[0038] In the brace member adjustment process (S107), the brace member is adjusted so as to match the length of the diagonal line of the width-adjusted frame body 2. Specifically, the shuttlecock portion 23 is cut along the cutting groove 27 so as to match the interval between the opposing corners of the frame body 2.

[0039] Next, the brace members 20, whose length has been roughly adjusted by cutting the shuttlecock portion 23 along the cutting grooves 27, are placed on opposing corners of the frame body 2, and fine adjustment is performed so that the length matches the diagonal length of the frame body 2 after the width adjustment by adjusting the screw portion 25 of the extension portion 24 and the screwing position of the turnbuckle 22, and the brace members 20 are attached to the corners of the frame body 2 through any of the mounting holes 26 of the shuttlecock portion 23. At this time, the brace members 20 are attached to the frame body 2 by selecting any of the mounting holes 26 of the shuttlecock portion 23 and attaching it with a fastening means such as a bolt. Fastening holes for attaching the brace members 20 are formed in advance in the corners of the frame body 2.

[0040] Thus, according to the gate width adjustment method using the brace member 20 of this embodiment, the length of the brace member 20 can be roughly adjusted by cutting the shuttlecock portion 23 to match the diagonal length of the adjusted frame body 2, and then the length of the brace member 20 can be finely adjusted by the turnbuckle 22 and the screw portion 25, so that the width adjustment range can be increased and the gate width can be flexibly adjusted according to the construction site. In addition, since the gate 40 can be created to match the interval between the posts 5 at the construction site, it is not necessary to adjust the width by processing a ready-made product and provide variations in the width dimension, so that manufacturing costs can be reduced.

[0041] In the above embodiment, the gate 40 is described as a single-leaf gate attached between the posts 5, but the gate 40 may be configured as a double-leaf gate with a pair of gates 40 provided between the posts 5. Also, the gate 40 may have three mounting holes 26 and two cutting grooves 27 formed in the shuttlecock portion 23, but these numbers can be increased or decreased as desired. For example, the gate 40 may have four or more mounting holes 26, and the cutting grooves 27 need not be formed between all of the mounting holes 26.

[0042] Furthermore, for attachment to the corner of the frame body 2, it is not necessary to select one attachment hole 26, and depending on the required fastening strength, attachment may be performed using a plurality of attachment holes 26 remaining after cutting the shuttlecock portion 23. It is clear from the claims that such modified or improved forms are also included within the technical scope of the present invention. [Explanation of symbols]
