Description

  The present invention relates to a shelf receiving structure for an assembly house used, for example, as a storeroom or a garage.

  The main plate part and the main plate part are bent inward from the left and right ends of the main plate part between the intermediate pillars with a cross-sectional shape having a groove opened on the indoor side and a lip bent inward of the groove on both side edges of the groove. In an assembly house with a wall panel provided with both side plate portions and bent plate portions that are continuously bent from the inner ends of the side plate portions into the grooves of the studs, a shelf board is provided indoors. Generally, shelves are attached to the studs.

  However, since the stud has a cross-sectional shape having a groove that opens to the indoor side, the mounting of the shelf holder to the stud is for clamping the side plate portion of the stud and a part of the shelf holder and its tightening bolt, or Bolts and nuts that connect the side plates of the studs and a part of the shelf support are required. In either case, the shelf support structure has a large number of components, and the installation work using tools becomes a shelf support. It took quite a while to install.

  By the way, in Patent Document 1, a shelf support column having an L-shaped cross section in which a plurality of through holes are formed at intervals in the vertical direction is connected to a joint between wall panels with bolts and nuts, There is described a shelf support structure for an assembly house in which a claw portion of a locking piece provided on the upper rear side is inserted and locked in the through hole, and the shelf support is supported by a shelf support column.

  According to this shelf support structure, the shelf support can be quickly attached to the shelf support column by a one-touch operation of inserting and locking the claw portion of the locking piece into the through hole. Therefore, the stability of the shelf support in the upper and left and right directions is poor, and the dedicated shelf support column, labor and tools for installing the shelf support column are required, so the shelf support as a whole It can be said that there is not much difference from the above-mentioned general prior art in that it takes a long time to mount the above. Further, in this shelf support structure, since the shelf support column must be attached in advance to the position where the shelf support is to be attached, the degree of freedom of the shelf support attachment position is low, and it is very difficult to change the shelf support attachment position. There is a problem of requiring time.

  The shelf receiving structure for an assembly house described in Patent Document 2 has been previously proposed by the applicant of the present invention to solve these problems, and as shown in FIGS. The main plate portion 5 and the main plate portion 5 are inward from the left and right ends of the main plate portion 5 between the intermediate post 1 and the intermediate post 1 having a groove a that is open and lip la that is bent inwardly on both side edges of the groove a. An assembly house provided with a wall panel 2 provided with both side plate portions 6 that are bent and a bent plate portion 7 that is continuously bent from the inner end of each side plate portion 6 into the groove a of the stud 1. In this embodiment, at least two through holes b are formed in the bent plate portion 7 at intervals in the vertical direction, and the upper locking pieces 15 provided at the rear ends of the shelf supports 3a and 3b are formed in these through holes b. The claw portions 15a and 15b and the claw portion 16a of the lower locking piece 16 are inserted and locked, and the shelf supports 3a and 3b are connected to the wall panel. It is characterized in that configured to support at 2.

  Note that the folded plate portion 7 is provided with a double-layered plate portion that is bent twice, and the through hole b is formed in the double-layered plate portion. Then, the upward claw portion 15 a and the downward claw portion 15 b formed on the upper locking piece 15 are locked to the upper and lower edges of the upper through-hole b, and the downward claw portion formed on the lower locking piece 16. It is comprised so that 16a may be latched to the lower edge part of the lower through-hole b.

  According to this shelf support structure, a through hole b is formed in the bent plate portion 7 of the wall panel 2 that is continuously bent and inserted into the groove a of the stud 1 and is provided at the rear ends of the shelf supports 3a and 3b. Since the claw portions 15a, 15b of the upper locking piece 15 and the claw portion 16a of the lower locking piece 16 are inserted and locked, the cross pillar 1 has a cross-sectional shape having a groove a opened to the indoor side. However, the shelf supports 3a and 3b can be quickly and stably attached by one-touch operation, and the shelf supports 3a and 3b are attached to the bent plate portion 7 of the wall panel 2, and the shelf supports 3a and 3b are attached to the wall panel 2. Therefore, there is an advantage that a dedicated shelf support column and its mounting effort are not required, the degree of freedom of the shelf support mounting position is high, and the shelf support mounting position can be changed quickly.

  However, in this shelf support structure, the shelf supports 3a and 3b are supported only by the wall panel 2, and only the wall panel bears the entire load applied to the shelf board 4. When a heavy load is applied to the shelf board 4 due to hanging or a heavy load is placed on only a part of the shelf board 4, the wall panel 2 itself bends and the wall panel 2 receives the shelf holder. There was a problem in terms of strength that both 3a and 3b rushed to the indoor side.

  That is, in the assembly house, the corner pillar and the stud 1 are made of a steel plate having a thickness of about 1 to 3 mm because the corner pillar and the pillar are configured to bear most of the vertical load. The wall panel 2 is generally made of a steel plate having a thickness of about 0.5 mm and has a considerably low strength. Therefore, the bent plate part 7 bent toward the groove a of the stud 1 is formed on both side plate parts 6 bent inward from the left and right ends of the main plate part 5 of the wall panel 2, and the bent plate Even if the double-layered plate portion is provided in the portion 7 to increase the strength of the end portion, the entire wall panel 2 is not reinforced, and the main plate portion 5 and the side plate portions 6 remain low in rigidity. Moreover, since the through-hole b is notched in the bent plate portion 7 of the wall panel 2 that is originally thin and weak in strength, the strength is reduced by that amount, and the weak point in strength due to the notch ( Since the upward claw 15a of the upper locking piece 15 is hooked on the indoor side by hooking the upper locking piece 15 on the edge of the through-hole b), even if the periphery of the through-hole b is reinforced with a double plate as shown in the drawing, the strength is much higher Does not go up. Therefore, when the concentrated load more than expected was applied to the shelf board 4, the wall panel 2 could not withstand the pulling force to the indoor side, and the wall panel 2 was pushed out to the indoor side together with the shelf supports 3a and 3b. It is.

Japanese Utility Model Publication No. 54-18004 JP 2006-158736 A

  The present invention has been made in view of the above-mentioned problems. The object of the present invention is to improve the invention of the previously proposed Japanese Patent Laid-Open No. 2006-158736 (Patent Document 2), and the invention has many features. Advantages (The shelf support can be mounted quickly and stably by a one-touch operation despite the cross-sectional shape of the studs having an opening on the indoor side, and there is no need for a dedicated shelf support column or mounting effort. The shelf panel mounting position has a high degree of freedom, and the shelf mounting position can be changed quickly, and at the same time, the wall panel itself bends when a concentrated load is applied to the shelf board. It is an object of the present invention to provide a robust shelf support structure for an assembly house that solves the problem of strength that wall panels are pushed out to the indoor side together with the shelf support.

  In order to achieve the above object, technical measures taken by the present invention are as follows. That is, the invention according to claim 1 includes a main plate portion and a main plate between a middle pillar and a middle pillar having a groove that is open on the indoor side and a lip that is bent inward of the groove on both side edges of the groove. Assembly with wall panels provided with both side plates bent inwardly from the left and right ends of each portion, and bent plate portions bent continuously from the inner end of each side plate portion into the groove of the stud In the house, at least two through-holes are formed in the bent plate portion with a space in the vertical direction, and the rear end of the shelf support is formed with an upward claw portion and a downward direction corresponding to these through-holes. An upper locking piece having a claw portion and a lower locking piece having a downward claw portion are provided, and the upward claw portion of the upper locking piece is bent to the indoor side as the upper end portion is bent sideways. The upper locking piece is inserted into the upper through hole, and the lower locking piece is inserted into the lower through hole. The downward hooks of the side locking pieces and the lower locking pieces are locked to the lower edge portions of the respective through holes, and the upward hook portions of the upper locking pieces are locked to the lip of the stud. It is characterized in that it is configured to be supported by a stud and a wall panel.

  Invention of Claim 2 is the shelf receiving structure of the assembly house of Claim 1, Comprising: The double-ply board part by which the bending plate part was bend | folded by double was provided in the said bending board part, The said double-ply board part WHEREIN: While forming the through hole, the vertical plate portion positioned between the shelf support portion of the shelf support and the upper locking piece and the lower locking piece was bent at a substantially right angle with respect to them. It is characterized by the fact that the bent vertical plate portion bent substantially at a right angle is in surface contact with the bent plate portion of the wall panel.

  According to the first aspect of the present invention, the upper locking piece provided at the rear end of the shelf receiver is formed with a through hole in the bent plate portion of the wall panel that is continuously bent into the groove of the stud. Since the claw portion of the lower side and the claw portion of the lower side locking piece are inserted and locked to the edge of the through hole or the lip of the stud, the cross pillar has a groove having an opening on the indoor side. Regardless, the shelf holder can be quickly and stably attached by one-touch operation, and the shelf holder is attached to the bent plate part of the wall panel, and the shelf holder is supported by the stud and the wall panel. A support post and its installation work are not required, and the degree of freedom of the shelf support installation position is high, and the shelf support installation position can be changed quickly.

  In particular, according to the first aspect of the present invention, the upward claw portion of the upper locking piece has a shape bent to the indoor side as the upper end portion is bent laterally, and the upward claw portion is formed into the lip of the stud. Because the shelf holder is supported by the stud and the wall panel, the entire load applied to the shelf board is borne by the wall panel and the stud that is stronger than the wall panel. When a concentrated load more than expected is applied to the plate, it is possible to solve the conventional problem that the wall panel itself bends and the wall panel is pushed together with the shelf support to the indoor side.

  In addition, in the state where the upward claw portion of the upper locking piece is locked to the lip that is bent inward from the both side edges of the groove of the stud, the upward claw portion is laterally moved between the lip and the inner surface of the stud. The movement of the rack is restricted, and backlash in the lateral direction of the shelf holder can be reduced.

  According to the second aspect of the present invention, the double-folded plate portion that is double-folded is provided on the bent plate portion of the wall panel that is continuously bent toward the groove of the stud. Since the through-hole is formed, the periphery of the through-hole is reinforced, and when a vertical load is applied to the shelf holder, the tensile force acting on the upper locking piece is supported by the studs, and the edge of the through-hole is deformed. Can be prevented.

  That is, when a vertical load is applied to the shelf holder due to the weight of the article placed on the shelf board, a forward tensile force (in a direction of coming out from the through hole) acts on the upper locking piece, and the lower locking is performed. Although a compressive force in the opposite direction acts on the piece, since the upper locking piece is provided with an upward claw portion and a downward claw portion, the upward claw portion is configured to be locked to the lip of the stud, The tensile force is supported by the studs, and no tensile stress acts on the upper edge of the through hole. In addition, the vertical plate portion positioned between the shelf support portion of the shelf support and the upper and lower locking pieces is bent at a substantially right angle in plan view with respect to them, and this substantially right angle. The compressive stress is dispersed by bringing the bent vertical plate portion bent into a surface contact with the bent plate portion of the wall panel.

  Therefore, the edge of the through hole can be prevented from being deformed, and a robust shelf mounting structure is realized. For example, one shelf plate having a wide width corresponding to two sheets is replaced with three shelf holders ( It is also possible to support the shelf board with a total of three shelf supports including two shelf supports that support the left and right ends of the shelf board and one shelf support that supports the center part of the shelf board. That is, in the conventional shelf support structure, when using a horizontally long shelf board (one shelf board having a wide width corresponding to two sheets) corresponding to the interval between the three studs, each of the left and right ends of the shelf board is 1 each. The shelf is supported by two shelf holders, and the center portion of the shelf board is supported by two shelf holders attached corresponding to the central studs. According to the invention of claim 2, a robust shelf board is provided. Since the mounting structure is realized, it is possible to omit one of the two shelf supports that support the central portion of the shelf board, and a significant cost reduction can be achieved.

  FIG. 1 exemplifies a shelf receiving structure for an assembly house used as a storeroom, for example, and FIGS. In the figure, reference numeral 1 denotes a cross-sectional shape of a pillar having a groove a opened on the indoor side and a lip 1a bent at an acute angle inward of the groove a on both side edges of the groove a. A wall panel 2 is installed between the studs 1 and 1. Reference numerals 3a and 3b denote shelf supports, and the shelf supports 3a and 3b are formed symmetrically with each other.

And a bent plate portion 7 that is continuously bent from the inner end toward the groove a of the stud 1.

  Each bent plate portion 7 is bent substantially straight from the inner end of the side plate portion 6 to the side at a substantially right angle and from the front end of the first plate portion 8 to the outside (outdoor side). Second plate portion 9, third plate portion 10 bent from the outer end of second plate portion 9 to the side at a substantially right angle, and fourth plate portion bent at a substantially right angle from the tip of third plate portion 10 to the outside. 11, and a double-layered plate portion that is double-folded from the outer end of the fourth plate portion 11 to the inner end of the second plate portion 9. A plurality of vertically long rectangular through-holes b are formed in the second plate portion of the third plate portion 10 at regular intervals in the vertical direction.

  Further, as shown in FIGS. 4 and 10, the first plate portion 8 in the bent plate portion 7 is formed with connecting metal fitting insertion holes c at a plurality of positions in the vertical direction, and both side plate portions of the wall panel 2. A plurality of bolt insertion holes d and e are formed at positions facing each other on both side plate portions of 6 and the stud 1. And it is comprised so that the stud 1 and the wall panel 2 may be connected by screwing the volt | bolt 13 inserted from the said bolt insertion holes d and e into the screw hole of the linking metal fitting 12 inserted in the connection metal fitting insertion hole c. is there.

  In addition, the spacer 1 and the shelf supports 3a and 3b are manufactured with a thick (for example, 1-3 mm) steel plate, and the wall panel 2 is manufactured with a thinner (for example, 0.5 mm) steel plate.

  Since the shelf receivers 3a and 3b are symmetrical, only the shelf receiver 3a on one side will be described. The shelf receiver 3a extends in the horizontal direction as shown in FIGS. 1 to 3, 5, and 6. The shelf board support part 14, the upper side locking piece 15 and the lower side locking piece 16 provided at the rear end of the shelf receiver at a distance corresponding to the through hole b, the shelf board support part 14 and the upper side relation A vertical plate portion 17 is provided between the stop piece 15 and the lower locking piece 16, and the shelf plate 4 is positioned on the vertical plate portion 17 at positions corresponding to the front and rear ends of the shelf plate support portion 14. For this purpose, notches f and g are formed.

  As shown in FIGS. 2 and 3, bent portions 4 a and 4 b that engage with the notches f and g are formed at the front and rear ends of the shelf plate 4, and the shelf plate support portions 14 are formed at the left and right ends. A bent portion 4c to be fitted is formed. Then, with the bent portion 4a at the front end of the shelf plate 4 engaged with the notch portion f at the front end of the shelf plate support portion 14, the bent portion 4b at the rear end of the shelf plate 4 is connected to the rear end of the shelf plate support portion 14. The shelf board 4 is configured not to move forward, backward, left and right by being dropped into the notch g from above and engaged. 4 d and 4 e are decorative caps made of synthetic resin that conceal the edges of the shelf board 4.

  The upper locking piece 15 is provided with an upward claw portion 15a and a downward claw portion 15b. The downward claw portion 15b is configured to be engaged with the lower edge portion of the upper through-hole b. The upward claw portion 15a has an upper end portion as shown in FIGS. 4 and 6-8. It is formed in a shape that bends indoors as it bends laterally, and is configured to be engaged with the lip 1a of the stud 1 as shown in FIGS. The lower locking piece 16 is provided with only a downward claw portion 16a so as to be locked to the lower edge portion of the lower through hole b.

  As shown in FIGS. 2 and 5, the vertical plate portion 17 is bent at a substantially right angle in a plan view with respect to the shelf support portion 14, the upper locking piece 15, and the lower locking piece 16 (so-called “so-called”). Z bent shape), and the bent vertical plate portion (Z bent plate portion) 17a bent substantially at a right angle is configured to be in surface contact with the first plate portion 8 of the bent plate portion 7 of the wall panel 2. It is. Further, a part of the bent vertical plate portion 17a to be brought into surface contact between the upper side locking piece 15 and the lower side locking piece 16 is cut up to the outdoor side at a substantially right angle, and its tip is cut up and raised. The latching piece 17b with respect to the side-plate part 6 of the wall panel 2 is comprised.

  According to said structure, the through-hole b is formed in the bending board part 7 of the wall panel 2 bent and arranged toward the inside of the groove | channel a of the stud 1, and shelf receptacle 3a, 3b is formed in these through-holes b. The claw portions 15a and 15b of the upper locking piece 15 provided at the rear end and the claw portion 16a of the lower locking piece 16 are inserted, and the downward claw portion 15b of the upper locking piece 15 is inserted into the upper through hole b. The lower claw portion 16a of the lower locking piece 16 is locked to the lower edge portion of the lower through-hole b on the lower edge portion, and the upward claw portion 15a of the upper locking piece 15 is locked to the lip 1a of the stud 1 Since it is locked, the shelf supports 3a and 3b can be quickly attached by a one-touch operation despite the cross-sectional shape of the stud 1 having the groove a opened to the indoor side. Although shelf holders 3a and 3b are attached to the bent plate portion 7, Since the shelf supports 3a and 3b are supported by the studs 1 and the wall panel 2, there is no need for a dedicated shelf support column or its mounting effort, and there is a high degree of freedom in the shelf support mounting position, and the shelf support mounting position can be changed. Can be done quickly.

  In particular, according to the above-described configuration, the upward claw portion 15a of the upper locking piece 15 has a shape bent to the indoor side as the upper end portion is bent laterally, and the upward claw portion 15a is formed into the lip of the stud 1. Since the shelves 3a and 3b are supported by the spacers 1 and the wall panels 2 by being locked to 1a, the pillars having a higher strength than the wall panels 2 and 2 can be applied to the total load applied to the shelf 4 1 and when the concentrated load more than expected is applied to the shelf 4, the wall panel 2 itself is bent and the wall panel 2 is pushed together with the shelf supports 3 a and 3 b to the indoor side. Can solve problems.

  In addition, according to the above configuration, the double plate portion that is double-folded is provided on the bent plate portion 7 of the wall panel 2 that is continuously bent into the groove a of the stud 1, and this double plate portion Since the through hole b is formed in the outer periphery, the periphery of the through hole b is reinforced, and when a vertical load is applied to the shelf supports 3a and 3b, the tensile force acting on the upper locking piece 15 is supported by the sturdy stud 1. In combination with this, deformation of the edge of the through hole b can be prevented.

  That is, when a vertical load is applied to the shelf receivers 3a and 3b due to the weight of the article placed on the shelf board 4, a tensile force in the forward direction (the direction of coming out from the through hole b) is applied to the upper locking piece 15. However, although the compression force in the opposite direction acts on the lower locking piece 16, the upper locking piece 15 is provided with an upward claw portion 15a and a downward claw portion 15b, and the upward claw portion 15a is connected to the intermediate pillar 1. Therefore, the tensile force is supported by the spacer 1 and no tensile stress acts on the upper edge of the through hole b. In addition, the vertical plate portion 17 positioned between the shelf support portion 14 of the shelf supports 3a and 3b and the upper locking piece 15 and the lower locking piece 16 is bent at a substantially right angle with respect to them. When the bent vertical plate portion 17a bent at a substantially right angle is brought into surface contact with the first plate portion 8 of the bent plate portion 7 of the wall panel 2, the compressive stress is dispersed.

  Accordingly, the edge of the through hole b can be prevented from being deformed, and a robust shelf mounting structure can be realized. For example, one shelf 4 having a wide width corresponding to two sheets is replaced with three shelves. It is also possible to support it with a receiver (a total of three shelf receivers that support the left and right ends of the shelf board and one shelf receiver that supports the center part of the shelf board).

  In other words, when the horizontal shelf plates 4 corresponding to the intervals between the studs 1 are erected continuously from side to side, the folded plate portions of the wall panels 2 installed on both sides of the studs 1 are usually provided as shown in FIG. 7, the claw portions 15a, 15b of the upper locking piece 15 of the shelf supports 3a, 3b and the claw portion 16a of the lower locking piece 16 are respectively inserted and attached to the through holes b formed in Instead of the two shelf boards, a horizontally long shelf board (one shelf board having a wide width corresponding to two sheets) corresponding to the interval between the three pillars 1 can be used. In this case, in the conventional shelf support structure, the left and right end portions of the horizontally long shelf plate are each supported by one shelf support, and the central portion of the shelf plate is attached by two shelf supports corresponding to the central pillar. Although it was necessary to support in terms of strength, according to the above configuration, a robust shelf mounting that bears the total load applied to the shelf by the pillar 1 and the wall panel 2 that are stronger than the wall panel 2. Since the structure is realized, it is possible to omit one of the two shelf supports that support the central portion of the horizontally long shelf board, which can greatly reduce the cost.

  Further, according to the above configuration, in the state where the upward claw portions 15a of the upper locking piece 15 are locked to the lip 1a bent from the both side edges of the groove a of the inter-column 1 to the inside of the groove a, the upward claw portion 15a is in a state in which the lateral movement is restricted by the lip 1a and the inner side surface of the stud 1, and the locking piece 17b provided on the bent vertical plate portion 17a contacts the side plate portion 6 of the wall panel 2. By contacting, the further lateral movement is restricted, so that the backlash in the lateral direction of the shelf supports 3a and 3b can be remarkably reduced.

  Although the present invention has been described based on the illustrated embodiment, the present invention is not limited to the illustrated embodiment. For example, three or more locking pieces are formed at the rear end of the shelf support. Thus, the uppermost locking piece is used as the upper locking piece 15 and the remaining plurality of locking pieces are used as the lower locking piece 16, or the entire bent plate portion 7 is double-folded. Needless to say, the present invention can be implemented in various modes without departing from the gist of the present invention, such as being configured as a two-layered plate portion.
