The frequency of occurrence of major earthquakes tends to increase, and the cause of injuries in recent major earthquakes is about 30 to 50% when furniture falls or falls.
In the connection structure as described in Patent Document 1 or 2, when a large earthquake causes a large swing, shear stress or bending stress repeatedly acts on the bolt, and the bolt may be broken.
For example, when the bolt (15) is broken in the connection structure of Patent Document 1, the connection rod (4), which is a horizontal bridge member, is detached from the support column (3) and falls.
If the cross support member falls off from the post and falls, it may lead to personal injury, so that the cross support member does not fall from the post even if it receives a large shaking due to an earthquake. It is necessary to effectively reinforce the connection with the frame member.

  Therefore, in view of the above-mentioned situation, the present invention is intended to solve the problem that the support member and the lateral support can be effectively reinforced so that the support member does not fall from the support even when it receives a large shaking due to an earthquake. The point is to provide a reinforcing structure of the connecting portion with the member.

In order to solve the above-mentioned problems, the reinforcing structure of the connecting portion between the support column and the lateral mounting member according to the present invention is a lateral support connecting a plurality of supporting columns erected on the floor and upper end portions of adjacent supporting columns. Reinforcement structure of the connecting portion with the member,
It is characterized in that it comprises a post-cross-member connecting reinforcement which straddles between the adjacent pillars and the cross-members and which connects and secures them so as to integrate them (claim 1).

  According to such a configuration, the link / reinforcement between the support and the cross support member spans between the support and the cross support member with respect to the connection portion between the support and the cross support member so as to integrate and fix them. As a result, the connecting portion can be effectively reinforced so that the cross member does not fall from the support even when it receives a large shaking due to an earthquake.

  Here, the post is capable of attaching the cross-bridge member in four directions whose directions are changed by 90 ° circumferentially around a vertical axis, and the connection reinforcement between the post and the cross-bridge member used in the four directions It is a preferred embodiment to make the device common (claim 2).

  According to such a configuration, since the connecting reinforcement between the support and the horizontal support is common to the four directions, the connecting portion between the support and the horizontal support is L-shaped in plan view, T Even in the case of crosses in the shape of a letter or a cross, reinforcement can be performed with the support brace for connecting the cross struts of the same shape, so that the manufacturing cost and the part management cost can be reduced.

  Furthermore, it is a more preferable embodiment to further include an inter-cross member interlinking member connecting reinforcement which spans the corners between the adjacent cross members and connects and fixes them so as to be integrated.

  According to such a configuration, at the connection portion between the support column and the cross member, the cross member between the cross members is straddled at the corner between the adjacent cross members, and connecting and fixing them so as to integrate them. Further, the connection portion can be reinforced more effectively so that the cross-bridge member does not fall from the support even when it receives a large shaking due to an earthquake.

Furthermore, the post is
A central structure at the center of the column,

Equipped with
The cross-bridge member is provided with a connecting member having a protrusion projecting toward the post,
The protrusion has an inclined surface formed between the adjacent inclined wall portions and housed in the internal space of the column and in contact with the wall surface of the inclined wall portion.
It is more preferable that the post and the cross-bridge member be connected in a state in which the inclined surface of the projection abuts on the wall surface of the inclined wall by screwing the projection to the central structure. It is an embodiment (claim 4).

According to such a configuration, the central structure at the center of the column is a member mainly responsible for strength, and the outer wall forming body having the inclined wall portion and the side wall portion reinforces the central structure and blocks the opening of the column. It becomes a member which attaches a cover body.
In addition, the projecting portion of the connecting member attached to the horizontal extending member has an inclined surface which abuts on the wall surface of the inclined wall portion.
Therefore, when the projection is accommodated in a substantially trapezoidal space in a plan view in the column, and the projection is screwed to the central structure of the column, the inclined surface of the projection abuts the wall surface of the inclined wall. Since the contact state is maintained and the contact state is maintained, the connection strength of the connection portion between the support and the horizontal cross member becomes high, so that the strength of the connection portion becomes higher in addition to the reinforcing effect by the connection reinforcing tool.

Furthermore, the connecting member has a vertical line hole.
It is a still more preferable embodiment that the post-cross member connecting reinforcement has an opening located above the wire passing hole (Claim 5).

  According to such a configuration, the opening portion and the connection of the connection reinforcement between the pillar and the lateral bridge member are effectively reinforced while the connection part between the pillar and the lateral bridge member is effectively reinforced by the joint reinforcement between the pillar and the lateral bridge member. Wiring can be passed in the vertical direction from the wire hole of the member, so the wiring workability is enhanced.

  As described above, according to the reinforcing structure of the connection portion between the support column and the horizontal support member according to the present invention, the horizontal support member is effectively prevented from falling from the support column even when it receives a large shaking due to an earthquake. It produces remarkable effects such as reinforcement.

Therefore, as shown in FIG. 5, the wiring C can be delivered through the through hole B from the cross beam 2 to the post 1 and / or from the post 1 to the cross beam 2.

<Post that is a post>
The post 1 is made of, for example, an aluminum alloy, and has a square tube portion 11 having a square cross section, which is a central structure at the center of the post, as shown in the cross sectional view of FIG.
Further, the post 1 is an outer wall forming body, and includes four inclined wall portions 12 extending in a direction (X1, X2, Y1, Y2) extending outward the diagonal line of the square from the corner portion of the rectangular tube portion 11; 12, and side walls 13 and 13 formed by bending the tip of the inclined wall 12 inward in the width direction, and the ends of the side walls 13 and 13 are bent toward the square cylinder 11 It has the parts 14 and 14.
The bent portions 14, 14,... Are the edge portions of the post 1, and the space between the facing bent portions 14, 14 is an opening I extending in the vertical direction shown in FIGS.
Furthermore, the side wall parts 13 and 13 which comprise the outer wall formation body of the post 1 have end part side 13A, 13A which opposes the horizontal beam 2 like FIG.
And between the inclined wall parts 12 and 12 which adjoin, four planar view substantially trapezoidal shaped internal space A, A, ... which were isolate | separated in the circumferential direction are formed.

The central structure of the post 1 is a member mainly responsible for strength, and the outer wall forming body of the post 1 reinforces the central structure, and also covers a post cover J which is a cover, which will be described later, and wiring irregularities. It becomes a member to which the stopper K is attached.
The central structure is not limited to the rectangular tube portion 11, and may have another shape such as a cylindrical shape.
Further, the inclined wall may be extended so as to be inclined outward in the width direction as it goes from the outer surface of the central structure toward the cross member 2.

  As shown in the exploded perspective view of FIG. 7, the countersunk tapping screws 28, 28,... Are inserted into the through holes 26A, 26A, ... at the lower end of the post 1 and screwed into the screw holes 15, 15,. Thus, the connector 26 is attached, and the stand S is attached by screwing the screw portion 27 of the stand S into the screw hole 26B of the connector 26. By rotating the stand S, the height of the post 1 can be adjusted.

<Wire runaway prevention device and post cover which is a cover body>
As shown in FIG. 3 and FIG. 7, after attaching the detachable wiring bump stopper K, K,... To the post 1 to the part to which the horizontal beam 2 of the side of the post 1 is not connected The post covers J, J,... Which are cover bodies for closing the openings I, I,.
The wiring bump stopper K is made of, for example, a synthetic resin such as polyacetal, polypropylene, polyethylene terephthalate, nylon, or ABS, and the post cover J is made of, for example, an aluminum alloy.

First, as shown in the cross-sectional plan views of FIGS. 8 and 9, the wire bump stopper K from the radially outer side is pressed against the wire C vertically inserted into the internal space A of the post 1 so as to press the wire C. Installing.
The wiring irregularity stopper K connects the mounting portions 19 and 19 with the mounting portions 19 and 19 and an outward movement restriction portion 20 which restricts the movement of the wiring C in the internal space A radially outward. And locking portions 21 and 21 for locking the locking claws 18 and 18 of the post cover J.
The mounting portion 19 includes a sliding surface 19A, an engaging convex portion 19B, and a locking piece 19C, and the sliding surface 19A is in surface contact with the inclined wall portion 12 of the post 1, and the engaging convex portion 19B is of the post 1 The locking piece 19 C is engaged with the guide groove G in the vertical direction of the inclined wall portion 12, and is engaged with the bent portion 14 which is the edge portion of the post 1.

  After the wire clasp K is attached to the post 1 as shown by the arrow in FIG. 8, the hooks 18, 18 of the post cover J are attached to the hooks 21 21 of the wiring clasp K as shown in FIG. The attachment of the post cover J is completed by locking.

According to the wiring structure of the post 1 using such a wiring bump stopper K, the wiring bump stopper K detachable from the post 1 has locking portions 21 and 21 for locking the post cover J.
Thus, in a state where the wire bump stopper K and the cover body J are removed from the post 1, the wire C is vertically inserted into the internal space A of the post 1, and the wire bump stopper K is mounted on the post 1 After that, the post cover J is locked to the locking portions 21 and 21 of the wiring irregularity stopper K.
Alternatively, after the wiring clasp K is attached to the post 1 and the post cover J is removed, the wiring C is vertically inserted into the internal space A of the post 1. The post cover J is locked to the stopping portions 21, 21.

Therefore, in the state where the wire runaway stopper K is attached to the post 1, the wire runaway stopper K can easily prevent the runaway of the wiring C in the internal space A of the post 1 and the locking of the wiring runaway stopper K By locking the post cover J to the portions 21 21, the opening I of the post 1 can be easily closed by the post cover J.
Therefore, the wiring processing operation which inserts the wiring C vertically in the internal space A of the post 1 and collects the wiring C can be simplified.

In addition, since the post cover J is attached to the anti-wiring clamp K attached to the post 1, the thickness of the post cover J is larger than the structure in which the post cover J is directly attached to the post 1 by the attachment member provided on the post cover J. The post cover J can be formed only of, for example, an aluminum alloy or the like, as well as being thin.
Therefore, when storing or transporting the post covers J, J, ..., space saving and handling become easy.

Therefore, the arched outward movement restricting portion 20 is easily elastically deformed in a direction (inward in the width direction) in which the both end portions are brought closer.
Therefore, since the wire bump stopper K can be easily attached to the post 1 in one action while elastically deforming the arch-like outward movement restricting portion 20, the wire bump stopper K is attached to the post 1 It is possible to improve the workability of work.

Further, in the wiring irregularity prevention tool K, the left and right sliding surfaces 19A, 19A make surface contact with the left and right inclined wall portions 12, 12 of the post 1, and the left and right engaging convex portions 19B, 19B The left and right locking pieces 19C, 19C are attached to the post 1 in a state where they are engaged with the guide grooves G, G in the directions and the left and right locking pieces 19C, 19C are locked in the left and right bent portions 14, 14 of the post 1.
Therefore, since the wiring irregularity prevention tool K is slidably supported in the vertical direction by the post 1 and can slide easily and reliably in the vertical direction, the irregularity of the wiring C inserted into the internal space A of the post 1 occurs. By sliding the wiring runaway stopper K to the position, it is possible to effectively suppress the runaway of the wiring C and to reduce the number of the wiring runaway stoppers K, K,.
Moreover, since the wiring bump stopper K can be moved in the vertical direction with the wiring bump stopper K attached to the post 1, wiring is performed to the internal space A of the post 1 with the wiring bump stopper K attached to the post 1. The workability in the case of performing the operation of inserting the through in the vertical direction can be improved.

<Horizontal beam which is a horizontal support member>

E (FIG. 12) is fitted, and the connection member 3 is inserted into the through hole (conical hole) 2A of the cross beam 2 through the countersunk screw 9 and screwed into the screw hole 3A of the connection member 3. Attached to 2 (see also FIG. 5).
The transverse beam 2 is provided with upper and lower longitudinal grooves 17A and 17B at its upper and lower portions. Here, in the state in which the connecting member 3 is attached to the lateral beam 2, the end portions in the longitudinal direction of the upper groove 17A and the lower groove 17B are notched 2B so as not to block the wire passing hole B of the connecting member 3. , 2B.

<Mounting structure of horizontal beam to post>
As shown in the enlarged plan view of the main part of FIG. 4, the enlarged longitudinal side view of the main part of FIG. 5, and the partially exploded perspective view of FIG. The mounting member O is fixed to the post 1 by inserting the mounting member O into a through-hole 16B of the rectangular cylinder 11 and screwing the mounting screw 32 into the screw hole 31B of the mounting member O.
The projecting portion 4 of the connecting member 3 attached to the lateral beam 2 is accommodated in the substantially trapezoidal internal space A in the plan view of the post 1, and the inclined wall portions 12, 12 partitioning the internal spaces A, A,. The inclined surfaces 5 and 5 which abut on the wall surfaces 12A and 12A.
Further, through holes 3B and downward notch holes 3C are formed at the upper and lower sides in the widthwise center of the projecting portion 4 of the connecting member 3, and the projecting portion 4 is formed at the side surface 11A of the square tube portion 11 of the post 1. The through holes 16A and 16A are formed at the upper and lower portions in the center in the width direction so as to face the upper and lower through holes 3B and the notched holes 3C.
The upper and lower screw holes 31A, 31A in the mounting member O fixed in the rectangular tube portion 11 of the post 1 as described above are the upper and lower through holes 16A, 16A in the width direction center of the square tube portion 11 of the post 1 The position is correct.

The attachment of the transverse beam 2 to the post 1 is, first, from the state shown in FIG. 14, the hooking portions 7B of the hooking pieces 7, 7 at both widthwise end portions of the transverse beam 2 shown in FIG. 6 is hooked to the side wall portion 13 of the post 1 shown in FIG.
In that state, the contact stop portions 7C and 7C of the hooking pieces 7 and 7 are in contact with the upper surfaces of the side wall portions 13 and 13 and held in place, and as shown in FIG. The holes 3 </ b> C and the upper and lower through holes 16 </ b> A, 16 </ b> A of the rectangular tube portion 11 are aligned.
Therefore, from the side of the horizontal beam 2, through the pan head tightening screw 10, 10 through the upper and lower through holes 3B and the notch holes 3C and the through holes 16A, 16A, screw the upper and lower screw holes 31A, 31A of the mounting member O Since the mating operation is easy, the workability of the operation of connecting the horizontal beam 2 to the post 1 can be improved.

  In the state where lateral beams 2 and 2 are attached to post 1 as shown in the main part enlarged perspective view of FIG. 15 (see also the main part enlarged plan view of FIG. 4 and the cross sectional view of FIG. 6) The inclined surfaces 5 and 5 of the projecting portion 4 of the connecting member 3 attached to the lateral beam 2 abut the wall surfaces 12A and 12A of the wall portions 12 and 12, and the contact state is maintained. The lateral beams 2 can be connected firmly.

Also, in the middle of screwing the protrusion 4 to the mounting member O, the shock absorbers 6, 6 at both ends in the width direction of the horizontal beam 2 abut the end side 13A, 13A of the post 1, and the end side 13A, 13A. When the shock absorbers 6 and 6 abut, the inclined surfaces 5 and 5 of the projecting portion 4 are separated from the wall surfaces 12A and 12A of the inclined wall portions 12 and 12, respectively.
Therefore, from the state where the shock absorbers 6, 6 abut the end side surfaces 13A, 13A, the screw fastening proceeds further, and in the state shown in FIG. 4 where the screw fastening is completed, the shock absorbers 6 at both widthwise ends , 6 and the lateral beam 2 is attracted to the post 1 so as to compress the shock absorbers 6, 6, the wall surfaces 12A, 12A of the inclined wall portions 12, 12 The inclined surfaces 5 and 5 of the projecting portion 4 abut on the rear surface.
That is, the shock absorbers 6, 6 at both widthwise end portions of the lateral beam 2 press-contact the end side surfaces 13A, 13A of the post 1, and the inclined surface 5 of the projection 4 of the connecting member 3 attached to the lateral beam 2, Since 5 is in contact with the wall surfaces 12A, 12A of the inclined wall portions 12, 12 of the post 1, the lateral beam 2 can be more firmly connected to the post 1.

As shown in FIGS. 4 and 6, in the post 1 to which the transverse beam 2 is attached from four directions equally divided by 90 ° in the circumferential direction, the radial direction outward of the square cylindrical portion 11 which is the central structure is circumferentially Four separated planarly viewed substantially trapezoidal spaces A, A,... Are formed.
The side surface 11A of the rectangular tube portion 11 is a flat surface, and the wall surfaces 12A and 12A of the inclined wall portions 12 and 12 can also be formed flat.
Thereby, when attaching the cross member 2 to the post 1 from the four directions, if the projection 4 of the connecting member 3 attached to the cross beam 2 is fastened to the square cylinder 11 of the post 1, the contact of the fastening surface and The contact between the inclined surfaces 5 and 5 of the protrusion 4 and the wall surfaces 12A and 12A of the inclined wall portions 12 and 12 results in the contact of the flat surfaces with each other.
Therefore, the cross member 2 can be accurately connected to the post 1 in a more stable state.
In addition, since manufacturing of the post 1 including the rectangular tube portion 11 which is a central structure and the connecting member 3 becomes easy including processing of through holes and the like to the rectangular tube portion 11, manufacturing cost can be reduced.

For example, in the state of FIG. 15, there is a line hole B having a size ranging from the inside of the cross beam 2 to the inside of the post 1 in the state of FIG. Wiring insertion space can be secured.
Furthermore, the projecting portion 4 of the connecting member 3 can be accommodated in the substantially trapezoidal internal spaces A, A,... In plan view by the planar shaped post 1 of FIG. The lateral beam 2 can be connected and fixed to the post 1 by fixing the protrusion 4 to the rectangular tube portion 11.

Furthermore, as shown in FIGS. 5 and 15, the transverse beam 2 is provided with upper and lower longitudinal grooves 17A and 17B at its upper and lower portions.
Therefore, the wiring between the upper concave groove 17A and the lower concave groove 17B in the longitudinal direction of the lateral beam 2 is made through the vertical wire passing hole B of the connecting member 3 attached to the lateral beam 2 and the wiring insertion space is large. Since it can be easily performed, the degree of freedom of wiring is improved.
Moreover, in the state of FIG. 15, for example, the wiring from one of the lateral beams 2 to the other can easily be made through the upper part of the post 1.

<Reinforcement for connection between pillars and horizontal members>
In a state shown in an enlarged perspective view of an essential part of FIG. 15 in which the lateral beams 2 and 2 are attached to the post 1, a post and a lateral are straddled between adjacent posts 1 and lateral beams 2 and connected and fixed to integrate them. The inter-member connection reinforcements R1 and R1 are attached as shown in the partially exploded perspective view of FIG. 16 and the enlarged main perspective view of FIG.
The column-cross member inter-member link reinforcement R1 is made of, for example, a steel plate, and has a step L, so it has higher torsional rigidity than a planar shape.

By inserting the countersunk head tightening screw 9 through the through hole (concave hole) 22A of the column / bridge connecting member R1 and screwing it into the screw hole 3A on the post 1 side of the connecting member 3, the column / crossover member The inter-connection reinforcement R1 is attached to the upper surface of the cross beam 2, which is a cross bridge member.
In addition, by inserting the countersunk tapping screw 29 into the through hole (concave hole) 22B of the column / bridge connecting member R1 and screwing to the screw hole 15 of the post 1, the column / cross unit connecting reinforcement is reinforced. The fixture R1 is attached to the upper surface of the post 1, which is a support.

  By attaching a column-to-bridge member connecting reinforcement R1 that straddles between the post 1 and the lateral beam 2 and couples and fixes them so as to integrate them, the lateral beam is received even if it receives a large shaking due to an earthquake. The connection between the post 1 and the cross beam 2 can be effectively reinforced so that 2 does not fall from the post 1.

Also, the post 1 can be attached with the horizontal beam 2 from four directions (four directions equally divided by 90 °), which are rotated 90 ° around the vertical axis, so that the post 1 and the horizontal beam can be attached The connection part with 2 is a form that intersects in a plan view T shape, in addition to a form in which the plan view L shape crosses as in the enlarged plan view of the main part in FIG. Or it forms the form which intersects in planar view cross shape like the principal part enlarged plan view of FIG.
In all of these forms, the support reinforcement between the support pillars and the horizontal support members R1 is made common, for example, as shown in FIG. 19, the support support reinforcements between the support pillars and the horizontal support members R1, R1, ... can be arranged without interference. Since the reinforcements R1, R1,... Having the same shape are used in all the above-mentioned embodiments, the manufacturing cost and the part management cost can be reduced.

In addition, as shown in FIG. 16, the column-to-post member cross reinforcement connecting reinforcement R 1 has an opening 23, and the opening 23 is located above the wire passing hole B in the vertical direction of the connecting member 3.
Therefore, while effectively reinforcing the connection portion between the post 1 and the horizontal beam 2 by the support between the post and the lateral bridge, the opening 23 of the joint between the support and the lateral bridge and the connection member 3 pass through Wiring can be passed in the vertical direction from the wire hole B, so the wiring workability is enhanced.

<Reinforcement between horizontal frame members>
