Japanese Patent Laid-Open No. 2002-294981

  However, since the movable part of the connecting part inserted into the back of the steel drawer as described above cannot be seen from the outside, if this movable part is in an abnormal direction, this abnormality There is a risk of overlooking. Details of such an abnormality of the movable part will be described later in the description of FIG.

  The present invention has been made to solve such a problem, and provides a metal floor bundle that allows an operator to easily find out even if a movable part has an abnormal orientation. For the purpose.

  In order to achieve the above object, the metal floor bundle of the present invention has a floor bundle main body, a height adjusting portion standing up from the foundation, and a coupling portion for coupling the height adjusting portion to the steel pulling. A steel fork that has a hollow inside and has an opening continuous in the longitudinal direction, and a pressure receiving portion that is folded inward and extends in the longitudinal direction at the upper end to be opposed to the opening. The connecting portion is configured to support the pressing member that matches the pressure receiving portion, a receiving member that receives the lower portion of the steel pulling, and the pressing member and the receiving member that penetrate through the pressing member and the receiving member. And a coupling member that sandwiches the opening between the two, and a bending piece for positioning formed at both ends of the pressing member so as to bend the both end portions along the pressure receiving portion. Up and down with respect to the longitudinal direction of the steel pull at the lower end of the bent piece It is summarized as the inclined edges are inclined to the direction is provided.

  That is, a positioning bent piece formed by bending the both end portions along the pressure receiving portion is provided at both end portions of the pressing member, and the lower end of the bent piece is vertically moved with respect to the longitudinal direction of the steel drawing. An inclined edge that is inclined in the direction is provided. Therefore, even when the pressing member is inclined and the inclined edge intersects the pressure receiving portion, and the pressing function of the pressing member is not normally performed, the inclined edge abuts the pressure receiving portion, An inclination of an angle corresponding to the inclination of the inclined edge appears on the coupling member. Therefore, even if the operator performs the assembly work in a state where the pressing member cannot be visually observed, the abnormal assembly of the pressing member can be easily and reliably detected by the inclination of the coupling member protruding from the steel pulling. .

  In the metal floor bundle according to the present invention, when the pressing member is in an abnormal direction with respect to the pressure receiving portion, the bi-folded piece so that the inclined edge contacts the pressure receiving portion in a state of intersecting the pressure receiving portion. If the pressing member is in an abnormal direction, the inclined edge portion contacts the pressure receiving portion while intersecting the pressure receiving portion. Therefore, the inclination which gives an inclination to a press member, and the inclination which shows abnormality in the coupling member which protrudes from steel pulling appears reliably, and an operator does not overlook abnormality.

  In the metal floor bundle of the present invention, when the inclined directions of the two inclined edges are the same direction, the pressing member is always inclined in a certain direction when the pressing member is in an abnormal direction. For this reason, in the event of an abnormality, the coupling member is surely inclined, and the abnormality is not overlooked.

  Next, the best mode for carrying out the metal floor bundle of the present invention will be described.

  1 to 10 show an embodiment of a metal floor bundle according to the present invention.

  The large pull supported by the metal floor bundle (hereinafter referred to as “floor bundle main body”) 2 according to the present embodiment is made of a steel plate, and the steel large pull 1 is formed on a foundation 7 as shown in FIG. It is supported by the standing floor bundle body 2. A joist 1a is fixed on the steel pulling 1, and a floor board 1b is attached thereon.

  As shown in FIG. 2, the steel overdraw 1 is formed into a hollow shape having a rectangular cross-section by press forming or roll forming a steel plate. An opening 12 extending along the longitudinal line of the pull 1 is formed. On both sides of the opening 12, both edges in the width direction of the steel plate are bent from the lower surface 11 to the inside (toward the upper surface 13) at a substantially right angle, and the primary folding portion 14a is formed. There is provided a folding portion 14 including a secondary folding portion 14b that is formed by being bent in the direction away from the opening portion 12 (toward the side surfaces 15 and 15).

  The primary folding portion 14a forms a folding wall plate, and the left and right folding wall plates are opposed to each other. The secondary folding part 14 b forms a pressure receiving part that is formed at the upper end of the folding wall plate and extends in the longitudinal direction of the steel pulling 1. In the following description, “folded wall plate 14a” and “pressure receiving portion 14b” are expressed as necessary. The pressure receiving portion 14b may be a straight cut surface obtained by cutting the upper end of the folding wall plate 14a, instead of a bent structure.

  On the other hand, as shown in FIG. 3, the floor bundle body 2 includes a base plate 21 and a height adjusting unit 22, and a coupling unit 30 is provided on the upper side of the height adjusting unit 22.

  The height adjusting unit 22 has an upper bolt 24 and a lower bolt 25 screwed into the upper and lower sides of the turnbuckle 23, and a spring washer 26 and a nut 27 are mounted on the upper bolt 24 and the lower bolt 25, respectively. The lower bolt 25 and the nut 27 screwed to this are reverse screws. By turning the turnbuckle 23, the height of the floor bundle body 2 is raised and lowered. After adjusting the height of the floor bundle body 2, the nuts 27, 27 screwed into the upper bolt 24 and the lower bolt 25, respectively, are tightened to the turnbuckle 23 side, so that the height (length) of the floor bundle body 2 is increased. Is fixed. The base plate 21 is welded and fixed to the lower end of the lower bolt 25.

  5 and 6 show the detailed structure of the connecting portion 30 in detail. That is, the upper bolt 24, a pressing member 31 fixed to the lower surface of the head 24a of the upper bolt 24, a large pull fixing nut 32 screwed into the upper bolt 24, the nut 32 and the pressing member 31 A receiving member 33 inserted into the upper bolt 24 and a spring washer 34 attached to the upper bolt 24 between the receiving member 33 and the nut 32. The upper bolt 24 penetrating the pressing member 31 and the receiving member 33 is a coupling member.

  The pressing member 31 is made of a steel plate and fulfills a pressing function for the pressure receiving portion 14b as will be described later. Further, the receiving member 33 is made of a steel plate, and has a function of receiving the lower part of the steel drawing 1 as will be described later.

  The pressing member 31 is formed by bending a rectangular steel plate as described above, and is provided with bent pieces 31a and 31a formed by being bent at a right angle downward at both ends. The interval between the two bent pieces 31a and 31a is set slightly larger than the interval between the two pressure receiving portions 14b and 14b, and the side portions of the pressure receiving portions 14b and 14b are formed inside the both bent pieces 31a and 31a. ing. The pressing member 31 is fixed to the head 24a of the upper bolt 24 by caulking or welding or the like, with the upper bolt 24 passing through a hole (not shown) in the center. The width of the pressing member 31 is set to be narrower than the width of the opening 12 of the steel drawer 1.

  The bent pieces 31a, 31a perform a positioning function for the pressing member 31 to press the pressure receiving portions 14b, 14b in the correct orientation. And the inclined edge parts 31b and 31b which inclined in the up-down direction with respect to the longitudinal direction line | wire of the steel drawing 1 are formed in the lower end of both bending pieces 31a and 31a. That is, as shown to FIG. 9 (B), it inclines with respect to the longitudinal direction line | wire of the steel drawing 1 which is the left-right direction of the figure. In addition, as shown in FIG. 3A, the inclined edges 31b and 31b are inclined with respect to the top surface 31c of the pressing member 31. Further, both inclined edges 31b and 31b are inclined in the same direction.

  The receiving member 33 is formed by bending a rectangular steel plate, and includes a bottom wall portion 33a and side wall portions 33b formed by being bent at a right angle upward at both ends in the longitudinal direction of the bottom wall portion 33a. 33b and upright portions 33c and 33c formed by cutting and raising the central portions at both ends in the width direction of the bottom wall portion 33a. A hole 33e (see FIGS. 5B and 10B) that is slightly larger than the bolt diameter of the upper bolt 24 is formed in the center of the bottom wall portion 33a. It is penetrated with, but is not fixed. The bottom wall 33a of the receiving member 33 is formed with a bulging portion 33d having a shape bulging downward. As shown in FIG. 5 (B), when the connecting portion 30 is not assembled to the steel pulling 1, the pressing member 31 is stored inside the bulging portion 33d. As a result, there is an effect that the coupling portion 30 is compactly gathered.

  The steel drawer 1 inserted with the gap between the side wall portions 33b and 33b substantially without a gap is held at the lower end portion by the side wall portions 33b and 33b and the bottom wall portion 33a. Further, the widths of both standing portions 33 c and 33 c are set slightly smaller than the width of the opening portion 12 of the steel pulling 1, so that the both standing portions 33 c and 33 c are open to the opening portion 12 of the steel pulling 1. It is designed to be inserted into.

  The steel drawer 1 and the floor bundle body 2 are coupled as follows. That is, as shown in FIG. 3, the lower end of the steel draw 1 is inserted into the receiving member 33 and is held by the bottom wall 33a and both side walls 33b, 33b of the receiving member 33, and the steel. Both standing portions 33 c and 33 c of the receiving member 33 are fitted in the opening 12 of the large draw 1. The pressing member 31 is inserted into the opening 12 of the steel draw 1 in accordance with, for example, the width direction of the opening 12 and the width direction of the pressing member 31, and then rotated 90 ° around the vertical axis. By being spanned between the pressure receiving portions 14 b and 14 b of the folding portion 14, the folding portion 14, that is, the opening portion 12 is sandwiched between the pressing member 31 and the bottom wall portion 33 a of the receiving member 33, and tightened by the nut 32. The steel drawer 1 and the floor bundle body 2 are joined together.

  As described above, when the pressing member 31 is spanned between the pressure receiving portions 14b and 14b in the correct orientation, the bent pieces 31a and 31a are in a state of being close to the side portions of the pressure receiving portions 14b and 14b, As a result, the bent pieces 31 a and 31 a perform the positioning function of the pressing member 31. That is, even if the pressing member 31 tries to rotate, the bent pieces 31a and 31a abut against the side portions of the pressure receiving portions 14b and 14b, and the rotation is suppressed.

  Normally, when using the floor bundle main body 2, as shown in FIG. 7, the steel drawer 1 is placed upside down on the soil, and the floor bundle main body 2 is turned upside down from above. After fixing all of them, the whole is turned upside down and installed at a predetermined position, and thereafter, the base plate 21 of each floor bundle body 2 and the foundation (bundle stone or soil concrete) 7 are bonded as shown in FIG. Then, the height of the floor bundle body 2 is adjusted by the turnbuckle 23.

  Next, a procedure for joining the steel pulling 1 and the floor bundle body 2 will be described.

  First, as shown in FIG. 8A, after confirming that there is a sufficient distance between the pressing member 31 and the nut 32, the width direction of the opening 12 and the pressing force are maintained while the floor bundle body 2 is held upside down. The pressing member 31 is inserted into the hollow portion from the opening 12 of the steel pulling 1 in accordance with the width direction of the member 31. At this time, the bottom wall portion 33a of the receiving member 33 is brought into contact with the lower surface of the steel pulling 1 and the end of the bottom wall portion 33a of the steel drawing 1 is connected to the bottom wall 33a of the receiving member 33. The receiving member 33 is placed on the steel draw 1 so that it is held by both side walls 33b, 33b and the both standing portions 33c, 33c are fitted into the opening 12 of the steel draw 1. Put it on.

  Next, a finger or the like is put into the opening 12 of the steel drawer 1 and, as shown in FIG. 8 (B), the pressing member 31 is rotated 90 ° about the vertical axis, and then FIG. 8 (C). As shown in FIG. 3, the floor bundle body 2 is pulled up to bring the pressing member 31 into close contact with the pressure receiving portions 14b, 14b of the folding portion 14 of the steel pulling 1. Finally, as shown in FIG. 8D, the nut 32 is tightened to the receiving member 33 side. If it does in this way, the folding part 14 (opening part 12) of the steel pulling 1 will be inserted | pinched between the press member 31 and the bottom wall part 33a of the receiving member 33, and the steel pulling 1 and the floor bundle main body 2 will be carried out. And are combined. In addition, what is necessary is just to follow a reverse procedure in order to disassemble the steel large drawing 1 and the floor bundle main body 2. FIG.

  In the connecting portion 30 between the steel drawer 1 and the floor bundle body 2, the pressing member 31 is inserted into the hollow portion from the opening 12 of the steel drawer 1 and the receiving member 33 is made of steel. After placing on the large pull 1, the pressing member 31 is rotated, and then the floor bundle body 2 is pulled up so that the pressing member 31 is brought into close contact with the pressure receiving portions 14 b and 14 b of the folding portion 14, and then the nut 32 is tightened. The steel drawer 1 and the floor bundle body 2 can be combined. Therefore, the joining operation can be performed easily and reliably. Moreover, since these dismantling operations can be easily performed, these members can be easily reused.

  Next, a procedure for confirming that the direction of the pressing member 31 is abnormal will be described.

  FIG. 10 shows a state in which the pressing member 31 is inclined and the inclined edge portions 31b and 31b intersect the pressure receiving portions 14b and 14b. The reason why the pressing member 31 faces in an abnormal direction as shown in FIG. 8 is that the operator views the receiving member 33 from above, so that the pressing member 31 becomes a shadow of the receiving member 33. This occurs because the direction in which the pressing member 31 is facing cannot be confirmed.

  When the operator pulls the upper bolt 24 in the state shown in FIG. 10A, the inclined edges 31b and 31b are substantially in close contact with the pressure receiving portions 14b and 14b as shown in FIGS. Therefore, the upper bolt 24 is inclined by an angle θ corresponding to the inclination angle of the inclined edges 31b and 31b. That is, the inclination of the angle θ occurs with respect to the vertical line. Since the upper bolt 24 is inclined as described above, the operator can immediately confirm that the direction of the pressing member 31 is abnormal. The operator who notices the abnormality in this manner inserts a hand or a tool from the opening 12 to change the direction of the pressing member 31 to the correct direction, that is, the direction shown in FIG. Assembly is completed in the order shown in (D).

  In the present invention, since the inclined edges 31b and 31b are formed on the bent pieces 31a and 31a, it can be surely found that the direction of the pressing member 31 is abnormal as described above. However, when the inclined edges 31b, 31b are not formed, such an abnormality is overlooked, and the connection between the floor bundle body 2 and the steel pulling 1 becomes abnormal.

  FIG. 12 is a diagram illustrating a state in which such an abnormality has occurred. As shown in FIGS. 12B and 12C, the bent pieces 31a and 31a of the pressing member 31 do not have the inclined edges as described above, and the height of the bent pieces 31a and 31a is unchanged over the entire length. . Therefore, as shown in FIG. 2A, the pressing member 31 is inclined and the lower edges of the bent pieces 31a and 31a are in close contact with the pressure receiving portions 14b and 14b, and the pressing member 31 is not inclined. . For this reason, even if the operator pulls the upper bolt 24, the upper bolt 24 is in a straight (vertical direction) state, so that the joining work of the floor bundle body 2 and the steel pulling 1 is completed without being noticed abnormally. End up. As shown in FIGS. 12B and 12C, when the nut 32 is tightened, the lower edges of the bent pieces 31a and 31a are strongly pressed against the pressure receiving portions 14b and 14b, so that the bent portions of the bent pieces 31a and 31a are As a result of buckling, the bond strength between the floor bundle body 2 and the steel pulling 1 does not reach a predetermined value, which causes the floor plate 1b to bend or squeal.

  In addition, in the connecting portion 30 between the steel pulling 1 and the floor bundle body 2, since the steel pulling 1 having the opening 12 is used, a conventional cross section for making a closed cross section is used. Since the caulking process or the like is not required, the manufacturing cost of the steel pulling can be reduced. Moreover, since what has the opening part 12 is used as the steel large drawing 1, the load of conveyance is carried out by thrusting the lower surface 11 and the side surface 15 of the two steel large drawings 1 into the opening part 12 of the other party. The appearance can be reduced, and the transportation efficiency can be increased. Moreover, since the steel drawing 1 has an open cross section, the edge of the steel plate is bent inward, and the edge of the steel plate is not exposed to the outside, so that it is safe to handle with bare hands. Moreover, since the standing part 33c inserted in the opening part 12 of the steel drawing 1 is formed in the receiving member 33, the rattling between the receiving member 33 and the steel drawing 1 is prevented. Can do. Further, since the secondary folding portions (pressure receiving portions) 14b and 14b are formed in the steel pulling 1, it is easy to fix the pressing member 31 in a predetermined direction and to reinforce the compressive force from the pressing member 31. Can play a role.

  In addition, in the said Example, although the steel drawing 1 is formed in the hollow shape whose cross-sectional shape is a rectangle, not only this but the steel drawing 1 will be provided if the opening part 12 is formed in the lower surface. Alternatively, a trapezoidal cross-sectional shape in which the lengths of the upper side and the lower side are different, or a hollow shape having another polygonal cross-sectional shape may be formed. Moreover, the steel draw 1 may be provided with grooves on each surface or may be corrugated for reinforcement or the like. Moreover, in the said Example, although the opening part 12 is formed so that it may extend along the longitudinal direction in the steel drawing 1, the opening part does not need to be formed continuously. Moreover, in the said Example, the pressing member 31 of the floor bundle main body 2 is inserted in the hollow part from the opening part 12 of the steel drawing 1, and after that, as shown in FIG. 8 (B), opening of the steel drawing 1 The pressing member 31 is prevented from being removed from the portion 12, but instead, the pressing member 31 is inserted into the hollow portion of the steel drawing 1 from the end of the steel drawing 1 and then the steel drawing 1. You may make it shift to a joint position.

  Moreover, in the said Example, although the folding part 14 of the steel large drawing 1 is comprised from the primary folding part 14a and the secondary folding part 14b, not only this but the folding part 14 is the steel large drawing 1 Any shape can be used as long as it can be received by being brought into contact with the pressing member 31.

  Furthermore, in the said Example, although the turnbuckle 23 was used as the height adjustment part 22 of the floor bundle main body 2, not only this but another height adjustment mechanism can also be used. In the case of the turnbuckle type, the upper bolt 24 screwed into the turnbuckle 23 also serves as the bolt of the coupling portion 30. However, when using another height adjusting mechanism, the bolt of the coupling portion 30 is used. You can prepare it separately.

  13 to 20 are views of the outer shape and the cross-sectional shape of the coupling portion 30. FIG. 13 is a plan view, FIG. 14 is a front view, FIG. 15 is a right side view, FIG. 16 is a left side view, and FIG. FIG. 18 is a bottom view, FIG. 19 is a sectional view, and FIG. 20 is a perspective view.

  The effects of the above embodiment are listed as follows.

  Bending pieces 31a and 31a for positioning formed by bending the both end portions along the pressure receiving portions 14b and 14b are provided at both end portions of the pressing member 31, and a large steel plate is provided at the lower ends of the bending pieces 31a and 31a. Inclined edges 31b, 31b are provided which are inclined in the vertical direction with respect to the longitudinal direction of the pull 1. Therefore, even if the pressing member 31 is inclined and the inclined edges 31b and 31b intersect the pressure receiving portions 14b and 14b, the pressing edge 31 does not function normally. , 31b abuts against the pressure receiving portions 14b, 14b, and an inclination of an angle corresponding to the inclination of the inclined edges 31b, 31b appears in the upper bolt 24. Therefore, even if the operator performs the assembly work in a state where the pressing member 31 is not visible, the abnormal assembly of the pressing member 31 can be easily and reliably detected by the inclination of the upper bolt 24 protruding from the steel pulling 1. can do.

  When the pressing member 31 is in an abnormal direction with respect to the pressure receiving portions 14b and 14b, the inclined edge portions 31b and 31b are in contact with the pressure receiving portions 14b and 14b in a state of intersecting the pressure receiving portions 14b and 14b. Since the distance between the bent pieces 31a and 31a is set, when the pressing member 31 is in an abnormal direction, the pressure receiving portions 14b and 14b are in a state where the inclined edge portions 31b and 31b intersect the pressure receiving portions 14b and 14b. Touch up. Therefore, the inclination which gives the inclination to the pressing member 31 and the upper bolt 24 protruding from the steel pulling 1 surely shows an abnormality, and the operator does not overlook the abnormality.

  When the inclined directions of both the inclined edges 31b and 31b are the same direction, the pressing member 31 is always inclined in a certain direction when the pressing member 31 is in an abnormal direction. Therefore, the upper bolt 24 is surely inclined when an abnormality occurs, and the abnormality is not overlooked.

  FIG. 11 shows a second embodiment of the metal floor bundle of the present invention.

  In this embodiment, the inclined directions of the inclined edges 31b and 31b of the both bent pieces 31a and 31a are reversed. Other than that, it is the same as that of the said Example, and attaches | subjects the same code | symbol to the same part.

  With the above configuration, when the pressing member 31 is in an oblique and abnormal direction, the inclined edge portions 31b and 31b do not contact the pressure receiving portions 14b and 14b with good stability, and the upper bolt 24 swings accordingly. It becomes easy. In such a state, the operator can immediately notice abnormalities and avoid abnormal assembly. Other than that, there exists an effect similar to the said Example.

  As described above, according to the present invention, since the inclined edge portion that can reliably detect the abnormal assembly of the pressing member is provided in the joint portion of the metal floor bundle, It is possible to reliably detect abnormal binding. As a result, the quality of housing is improved and a metal floor bundle with high market needs is obtained.
