Description

[Technical field]

[0001] The present invention relates to a prefabricated gate, and more particularly to a prefabricated gate in which welding of components is reduced. [Background technology]

[0002] Conventionally, a prefabricated gate includes a gate having a metal frame and a net fence, and a support post to which the gate is attached so that it can be opened and closed. Various types of prefabricated gates are known, and the prefabricated gates described in Patent Documents 1 and 2 are known, for example.

[0003] The prefabricated gate described in Patent Documents 1 and 2 is a prefabricated gate comprising a frame body consisting of a pair of horizontal frames and a pair of vertical frames, corner members attached to the four corners of the frame body, a center plate connecting the vertical frames to each other, and brace members arranged on diagonal lines of the frame body and connecting the corner members to each other, wherein the corner members have a base extending parallel to the front face of the frame body, a pair of frame mounting parts standing upright from the base and extending approximately parallel to the horizontal frames and the vertical frames, and a brace mounting member attached to at least one of the frame mounting parts, and the frame mounting parts have screw parts for fastening the horizontal frames or the vertical frames with fastening members.

[0004] With this type of prefabricated gate, the corner members attached to the four corners of the frame have a base extending parallel to the front of the frame, a pair of frame mounting parts standing up from the base and extending approximately parallel to the horizontal and vertical frames, and a brace mounting member attached to at least one of the frame mounting parts, and the frame mounting parts have screw parts that fasten the horizontal or vertical frames with fastening members, so that the horizontal frames, vertical frames and brace members can each be assembled with fastening means such as bolts. This makes it possible to easily assemble the prefabricated gate. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Patent Publication No. 2022-45480 [Patent Document 2] Patent Publication No. 2022-45481 Summary of the Invention [Problem to be solved by the invention]

[0006] However, in conventional prefabricated gates, the gate is attached to the post via a hinge, one side of which is attached to the post by welding, and the other side is fastened to the vertical frame by a bolt. Therefore, in the case of a double-opening gate, the left and right sides cannot be made the same shape, and there is a problem that a left and right gate must be prepared separately.

[0007] In addition, the corner members used in conventional prefabricated gates have a three-dimensional structure having a base that extends parallel to the front of the frame band and a pair of frame mounting parts that stand up from the base and extend approximately parallel to the horizontal and vertical frames.This means that there is a problem in that storage space is required when storing the corner members in a factory or warehouse before they are assembled into the frame material.

[0008] Furthermore, to address this storage space issue, there are eight types of single-sided gates with double openings and a drop bar attached to one side: double inward openings, right outer bar, left inner bar, right inner bar, double inward openings, left outer bar, right inner bar, double inward openings, right inner bar, left inner bar, double outward openings, left outer bar, right inner bar, double outward openings, right inner bar, left inner bar, double outward openings, right outer bar, left inner bar, double outward openings, left inner bar, right inner bar. There are four types of double drop bars installed on both gates: double opening with right outer bar and both outer drop bars; double inward opening with left inner bar and both inner drop bars; double outward opening with right outer bar and both outer drop bars; and double outward opening with left inner bar and both inner drop bars. There are 12 different gate specifications in total, with single and double drop bars. As orders cannot be placed until these gate specifications are decided, it is necessary to prepare all of these specifications in advance in order to shorten the lead time from order to delivery, which poses the problem of requiring a huge amount of storage space.

[0009] Therefore, the present invention has been made in consideration of the above problems, and has an object to provide a prefabricated gate that can be easily assembled without having to secure storage space, regardless of the gate specifications. [Means for solving the problem]

[0010] The prefabricated gate of the present invention comprises a frame body consisting of a pair of horizontal frames and a pair of vertical frames, corner members attached to the four corners of the frame body, a central plate connecting the vertical frames to each other, and brace members arranged diagonally on the frame body and connecting the corner members to each other, wherein the vertical frames consist of a pillar-side vertical frame and a gate-side vertical frame, the pillar-side vertical frame has a pair of hinge mounting holes formed symmetrically in the center of its longitudinal direction, and the gate-side vertical frame has a pair of drop mounting holes formed symmetrically in the center of its longitudinal direction.

[0011] In addition, in the prefabricated gate of the present invention, it is preferable that the corner members are each formed with a first mounting hole formed in the vertical frame and a second mounting hole formed in the horizontal frame.

[0012] In addition, in the prefabricated gate of the present invention, it is preferable that the first mounting hole and the second mounting hole each have two or more holes formed therein, and that the spacing between the first mounting holes is greater than the spacing between the second mounting holes.

[0013] Furthermore, in the prefabricated gate according to the present invention, it is preferable that the corner member is formed with a third mounting hole for mounting the brace member.

[0014] In the prefabricated gate according to the present invention, it is preferable that the third mounting hole is formed as an elongated hole.

[0015] In the prefabricated gate according to the present invention, it is preferable that the corner members are flat plates having a substantially square shape.

[0016] 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

[0017] In the prefabricated gate of the present invention, the vertical frame is composed of a post-side vertical frame and a gate-side vertical frame, the post-side vertical frame has a pair of hinge mounting holes formed symmetrically in the center of the longitudinal direction, and the gate-side vertical frame has a pair of drop mounting holes formed symmetrically in the center of the longitudinal direction, so that hinges can be fastened and fixed to the hinge mounting holes with bolts, and by rearranging the hinges, it is possible to accommodate either outward-opening or inward-opening specifications. Also, since the post-side vertical frame and the gate-side vertical frame have a pair of hinge mounting holes or a pair of drop mounting holes formed symmetrically in the center of the longitudinal direction, the gate can be used as a left-side or right-side gate by flipping the gate upside down, and by rearranging these as necessary, prefabricated gates of various specifications can be made.

[0019] 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.

[0020] Figure 1 is a front view of a prefabricated gate according to an embodiment of the present invention, Figure 2 is a front view of a gate that constitutes a prefabricated gate according to an embodiment of the present invention, Figure 3 is an exploded view of a gate that constitutes a prefabricated gate according to an embodiment of the present invention, Figure 4 is a front view showing a corner member of the prefabricated gate according to this embodiment of the present invention, Figure 5 is a diagram showing the installation state of the brace member of the prefabricated gate according to an embodiment of the present invention, and Figure 6 is a cross-sectional view along AA in Figure 1.

[0021] As shown in Figure 1, the prefabricated gate 10 of this embodiment has posts 11 fixed to a foundation 1 poured into the ground G, which are arranged at a predetermined interval, and has a pair of gates 20 attached between the posts 11 so as to be able to be opened and closed freely.

[0022] The gate 20 is attached so as to be freely opened and closed via a hinge 13 attached along the axial direction of the support pillar 11, and is supported by a hanging brace (not shown) that is hung from above the support pillar 11 as necessary.

[0023] In addition, the gate 20 has a drop rod 14 attached thereto so as to be able to move vertically and pass through a hole 15 formed in the ground G. By inserting the drop rod 14 into the hole 15, the gate 20 can be prevented from opening or closing and the gate 20 can be fixed in a closed state.

[0024] In addition, the pair of gates 20 are provided with a latch 24 attached to one of the gates 20 (the left gate 20 in Figure 1) so that it can be moved horizontally. By passing the latch 24 through the latch support portion 25 of the other gate, the pair of gates 20 can be prevented from opening and closing relative to each other, and the gates 20 can be fixed in a closed position.

[0025] As shown in FIG. 2, the gate 20 has a frame body including a pair of horizontal frames 21, 21 made of angle members having an L-shaped cross section, a vertical frame 22 made of a pillar-side vertical frame 22a and a gate-side vertical frame 22b, corner members 30 attached to the four corners of the frame body so as to connect the adjacent horizontal frames 21 and vertical frames 22, a center plate 23 arranged substantially parallel to the ground and near the center in the vertical direction so as to connect the pillar-side vertical frame 22a and the gate-side vertical frame 22b, and a brace member 28 arranged on a diagonal line of the frame body and connecting the corner members 30 to each other. The brace member 28 is preferably made of a bar material or the like, and ensures the rigidity of the gate 20. In addition, a net 27 is attached to the front of the frame body. The net 27 is preferably made of a metal wire mesh or the like in consideration of wind resistance and durability, but a flat plate such as a punched metal formed by arranging a plurality of predetermined through holes may also be attached.

[0026] The central plate 23 is a flat metal member made of steel plate or the like, and is connected to the pillar-side vertical frame 22a and the gate-side vertical frame 22b. The pillar-side vertical frame 22a and the gate-side vertical frame 22b are connected to the central plate 23 by conventional fastening means such as bolts and nuts. The central plate 23 has a bar 24 that is attached so as to be movable in the horizontal direction, and a bar support part 25 that supports the bar 24. The bar 24 is attached to one of the pair of left and right gates 20, and the other gate 20 is formed with only the bar support part 25, and the bar 24 that moves to protrude from one gate 20 can be supported by the bar support part 25 of the other gate 20.

[0027] In addition, a hinge 13 is attached to the pillar side vertical frame 22a on the support 11 side to attach the gate 20 to the support 11 so that it can be opened and closed freely, and a drop bar 14 is attached to the gate side vertical frame 22b on the gate 20 side so that it can be moved freely in the vertical direction.

[0028] As shown in Figure 3, the frame body of the gate 20 is composed of a pair of horizontal frames 21 arranged horizontally relative to the ground G, a pillar-side vertical frame 22a and a gate-side vertical frame 22b arranged vertically relative to the ground G, and corner members 30 connecting adjacent horizontal frames 21 and vertical frames 22.

[0029] A pair of horizontal frames 21 arranged above and below the frame body are elongated members having the same shape, with horizontal-frame-side corner member mounting holes 43 formed at both longitudinal ends. A plurality of horizontal-frame-side corner member mounting holes 43 (two in the prefabricated gate 10 according to this embodiment) are formed along the horizontal direction, and are formed to correspond to second mounting holes 32 formed in corner members 30 described below. In addition, it is preferable that the horizontal frames 21 have suspension brace mounting holes for mounting suspension braces (not shown) as necessary.

[0030] The pillar-side vertical frame 22a and the gate-side vertical frame 22b have vertical-frame-side corner member mounting holes 44 formed at both longitudinal ends on one face of the L-shaped cross section. A plurality of vertical-frame-side corner member mounting holes 44 (two in the prefabricated gate 10 according to this embodiment) are formed along the vertical direction, and are formed to correspond to first mounting holes 31 formed in the corner member 30 described later.

[0031] Furthermore, in the column-side vertical frame 22a, hinge mounting holes 41 are formed symmetrically about the center M along the vertical-frame-side corner member mounting holes 44 on the surface on which the vertical-frame-side corner member mounting holes 44 are not formed. The hinge mounting holes 41 are formed so that the hinges 13 described below can be fastened with bolts and nuts.

[0032] In the gate-side vertical frame 22b, drop mounting holes 42 are formed symmetrically about the center M along the vertical-frame-side corner member mounting holes 44 on the side where the vertical-frame-side corner member mounting holes 44 are not formed. The drop mounting holes 42 are fitted with the drop rods 14 so that they can move freely in the vertical direction. It is preferable that the drop rods 14 are fitted through drop guide members (not shown) that are fitted to the drop mounting holes 42.

[0033] 4, corner member 30 is a generally square flat plate member with cutouts 34 formed at the corners and, at one corner, a relief portion 35 which is a larger cutout than notch 34. Corner member 30 also has a first mounting hole 31 corresponding to vertical frame-side corner member mounting hole 44 described above, a second mounting hole 32 corresponding to horizontal frame-side corner member mounting hole 43, and a third mounting hole 33 to which brace member 28 is attached.

[0034] The first mounting holes 31 and the second mounting holes 32 are each formed in a plurality (two in the prefabricated gate 10 according to this embodiment), the first mounting holes 31 being formed along any side of the corner member 30, and the second mounting holes 32 being formed along a side perpendicular to the any side. Also, the intervals at which the first mounting holes 31 are formed are formed larger than the intervals at which the second mounting holes 32 are formed.

[0035] The third mounting hole 33 is formed as an elongated hole, and the longitudinal direction of the elongated hole is arranged so as to be approximately parallel to the diagonal line of the corner member 30. As shown in FIG. 5, the brace member 28 is attached to the third mounting hole 33 by a bolt and nut 37. At this time, it is preferable to assemble the corner member 30 and the brace member 28 with a spacer 36 interposed between them. By assembling the brace member 28 through the spacer 36 in this way, it is possible to prevent interference between the net 27 assembled to the frame and the brace member 28, and it is possible to prevent deformation or floating of the net 27 due to interference between the net 27 and the brace member 28.

[0036] Furthermore, the frame body constituting the gate 20 of the prefabricated gate 10 in this embodiment can be assembled by assembling the horizontal frame 21, the pillar side vertical frame 22a and the gate side vertical frame 22b into the first mounting hole 31 and the second mounting hole 32 of the corner member 30 via bolts and nuts, so that the frame body can be constructed only by assembly work using bolts and nuts without welding.

[0037] 6, the base end of the hinge 13 is attached to the hinge attachment hole 41 of the pillar-side vertical frame 22a with a bolt and nut, and the other end of the hinge 13 is attached to the pillar 11 with a bolt and nut. By configuring it in this way, the gate 20 can be attached to the pillar 11 so as to be able to be opened and closed freely.

[0038] Furthermore, the hinge mounting hole 41 formed in the pillar-side vertical frame 22a and the drop mounting hole 42 formed in the gate-side vertical frame 22b are formed on both ends of the pillar-side vertical frame 22a and the gate-side vertical frame 22b so as to be symmetrical about the center M. Therefore, after the pair of horizontal frames 21, the pillar-side vertical frame 22a and the gate-side vertical frame 22b are fastened with the corner members 30 to assemble the frame body, the hinge 13 and the drop rod 14 can be attached in predetermined positions. Even if the frame body is assembled as a set for the left and right gates that open both ways and is turned upside down, the height position of the hinge mounting hole 41 and the position of the drop mounting hole 42 can be configured to be in predetermined positions. Therefore, there is no need to prepare separate members for the left and right gates, and mistakes in assembling the left and right gates 20 can be prevented when installing the prefabricated gate 10.

[0039] In the prefabricated gate 10 of this embodiment described above, a pair of horizontal frames 21, a pillar-side vertical frame 22a, and a gate-side vertical frame 22b are fastened together by corner members 30 with bolts and nuts, and the hinge 13 attached to the pillar-side vertical frame 22a is also fixed with bolts and nuts. Therefore, welding is eliminated from the assembly of the gate 20, and all assembly is performed with bolts and nuts. This means that parts can be stocked regardless of the specifications of the prefabricated gate 10, and there is no need to secure storage space.

[0040] Furthermore, since the hinge mounting holes 41 and the drop mounting holes 42 are formed symmetrically at both ends of the pillar side vertical frame 22a and the gate side vertical frame 22b at the center M of the pillar side vertical frame 22a and the gate side vertical frame 22b, the hinges 13 and the drop rods 14 can be assembled regardless of the orientation of the gate 20, making it possible to rearrange the assembly to accommodate various gate specifications.

[0041] In the above embodiment, the left and right gate doors 20 are attached to the pillars 11 via the hinges 13, but for example, a suspension brace may be attached from above the pillars 11 and the suspension brace may be attached to the upper horizontal frame. 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]
