Description

  The present invention provides a special mounting part suitable for mounting a vertical member and a cross member as in the case of attaching a grid to a plurality of support columns, and a structure in which the cross member is assembled to the vertical member through the mounting part. Further, the present invention relates to an assembling method for assembling a cross member to a vertical member through the mounting part.

  For example, when assembling a lattice (horizontal lattice) to a support column, as can be understood from the description of Patent Document 1, conventionally, a fixing screw is passed from one side of the support column to the other, and a rectangular rotating screw is attached to the end of the fixing screw The rotating screw is held in a horizontal state and protruded from the column, and the lattice is also pressed horizontally against the column, and the protruding rotating screw is held in the groove formed in the longitudinal direction of the lattice. And the grid is engaged with the fixing screw so as not to come off. After the lattice is temporarily fixed to the support in this way, the fixing screw is tightened, and the rotating screw holder is rotated to assemble and fix the lattice to the support.

JP-A-60-168878

  However, according to the assembling method as described above, it is necessary to make the inclination of the lattice substantially coincide with the angle of the holding screw of the fixing screw. For example, it is necessary to keep the rotating screw holding projecting from the column horizontal and press it against the column with the grid leveled so that the rotating screw holding is stored in the groove. Otherwise, when the grid is pressed against the pillar side, the back of the grid hits the rotating screw holder and pushes the rotating screw holder until it contacts the side of the pillar, and the rotating screw holder is not stored well in the groove, This is because the lattice cannot be temporarily fixed by hooking the lattice onto the fixing screw. If it cannot be temporarily fixed, the fixing screw cannot be tightened. Therefore, it has been troublesome to assemble and install the grid on the support column.

  The present invention solves the above-mentioned problems, and a mounting part that allows a cross member such as a lattice to be easily and reliably assembled to a vertical member such as a support, and a vertical member via this mounting part. It is an object of the present invention to provide a structure in which a cross member is assembled, and an assembling method for assembling the cross member to the vertical member via the mounting part.

  In order to solve the above-mentioned problem, the invention according to claim 1 is provided between a fixing screw, a rotating screw holding screwed to a tip end side of the shaft portion of the fixing screw, and a head of the fixing screw and the rotating screw holding. And an elastic member.

  According to a second aspect of the present invention, in the first aspect, the elastic member is configured by a leaf spring, and an annular protrusion is formed around a screw hole on the back surface of the rotating screw. A center portion of the leaf spring is rotatably attached, and both side portions of the leaf spring are bent at an acute angle with respect to the center portion and protrude toward the screw head side.

  According to a third aspect of the present invention, in the second aspect of the present invention, a concave notch is formed at the tip of both sides of the leaf spring, and the tip of the both sides of the recess is bent.

  The invention according to claim 4 is a cross member provided with a dovetail groove along the longitudinal direction of the back surface of the vertical member standing on the installation surface via the mounting part according to claim 1 or 2. The end of the fixing screw penetrated from one side of the longitudinal member to the other side is projected, and the rotating screw holding member with the elastic member screwed to the end is attached to the cross member. It is characterized by being housed and fixed in the groove.

  The invention according to claim 5 has a dovetail groove along the longitudinal direction of the back surface of the plurality of vertical members erected on the installation surface through the mounting part according to claim 1 or 2. In attaching the cross member, the fixing screw is passed through from one side of the vertical member to the other side, and the rotating screw holder with the elastic member is screwed to the end of the fixing screw, and the rotating screw is supplied from the other side of the vertical member. Hold the horizontal screw in the horizontal state and engage the grooved part of the cross member with the protruding rotary screw holder with the elastic member to set it temporarily, then tighten the fixing screw and rotate the rotary screw holder together. And being assembled by engaging with the inside of the groove.

  According to the first aspect of the present invention, the attachment component is provided between the fixing screw, the rotating screw holder that is screwed to the shaft tip end side of the fixing screw, and the head of the fixing screw and the rotating screw holder. Since the elastic member is provided, when two members are fixed, when the fixing screw is passed through one member, the elastic member is arranged between the rotary screw holder and the above member. Due to the elasticity of the member, the rotating screw is biased away from the member. Therefore, when the other member is assembled to the above one member, the pressing force is released even if the other member hits the shaft end or the rotating screw and the fixing screw may be pushed back in the pulling direction. When it is done, the rotating screw holder is pushed back to the original position together with the fixing screw or does not lose the pressing force. For this reason, when assembling using the above-mentioned rotating screw holding, the assembly work of the other member becomes easy.

  In addition, after inserting the rotating screw holder into the groove portion of the other member, when the fixing screw is turned and tightened, it is rotated together and fitted into the groove portion so that it cannot be pulled out. At this time, since the rotating screw is formed in a substantially parallelogram shape, it can be deeply accommodated in the groove portion even if it does not rotate 90 degrees at the same time, so that the mounting strength is stabilized.

  According to a second aspect of the present invention, the elastic member is configured by a leaf spring, and an annular protrusion is formed around the screw hole on the back surface of the rotating screw, and the annular spring is formed on the annular protrusion. Since the central portion is rotatably attached, the leaf spring does not move freely on the shaft portion of the fixing screw. Therefore, the assembly work of the members can be performed stably and smoothly. In addition, since both side portions of the leaf spring are bent at an acute angle with respect to the central portion and protrude toward the screw head side, a reaction force against the pressing of the member can be effectively applied.

  According to the third aspect of the present invention, since the concave portions are formed at the tip portions of the both side portions of the leaf spring, the fixing screw interferes with the concave portions when the both side portions of the leaf spring are folded. In addition, since the tips on both sides of the recessed portion are bent, it can be handled safely.

  According to the invention which concerns on Claim 4, it had the dovetail groove part along the longitudinal direction of the back surface in the vertical material standingly arranged by the installation surface via the attachment component of Claim 1 or 2. A structure having a cross member attached thereto, wherein the structure has an end portion of a fixing screw that penetrates from one side of the longitudinal member to the other side, and rotates with the elastic member that is screwed to the end portion. Since the screw holder is housed in the groove of the cross member and fixed, the fixing screw is passed through the vertical member, and the horizontal member is pressed against the vertical member with the rotating screw holder protruding from the vertical member. When swallowing a rotating screw holder in the groove, even if the cross member hits the shaft end of the fixing screw or holding the rotating screw and the fixing screw is pushed back in the removal direction, the pressing force is released In addition, the rotating screw holder is pushed back together with the fixing screw. Therefore, the work of swallowing the rotating screw holder into the groove portion of the cross member can be repeated any number of times, and the assembly work of the other member is facilitated when assembling using the rotating screw holder.

  According to the invention which concerns on Claim 5, the dovetail groove part is formed along the longitudinal direction of a back surface to the some vertical material standingly arranged by the installation surface through the attachment component of Claim 1 or 2. In attaching the cross member, the fixing screw is passed through from one side of the vertical member to the other side, and the end of the fixing screw is screwed with the rotating screw holder with the elastic member from the other side of the vertical member. The rotating screw holder is protruded in a horizontal state, the groove portion of the cross member is engaged with the protruding rotating screw holder with the elastic member to temporarily fix it, and then the fixing screw is tightened and the rotating screw holder is held. Since it is rotated together and engaged with the inside of the groove, the vertical and horizontal members can be easily assembled.

  1 and 2 show a mounting part according to the present invention. The mounting part A is a metal fitting suitable for assembling a vertical member and a horizontal member, and includes a fixing screw 1, a rotating screw holder 2 that is screwed to the tip end side of the fixing screw 1, and a leaf spring (elastic member) 3. It consists of and.

  The fixing screw 1 is a normal screw composed of a screw head 1a and a screw shaft portion 1b.

  The rotating screw holder 2 is formed of a metal material in a substantially parallelogram shape, and a screw hole 4 is formed in the center. The screw hole 4 is formed by forming a screw groove in a burring portion, and an annular convex portion 5 is formed to protrude on the back side.

  The leaf spring 3 is composed of a central portion 3a and both side portions 6 and 6 thereof. A hole is formed in the central portion 3a, and the both side portions 6 and 6 are bent at an acute angle with respect to the central portion 3a. Arc-shaped recessed portions 7 are formed at the tips of the side portions 6 and 6. When both side parts 6 and 6 are folded and overlapped with each other, a circular shape is formed inside the both recessed parts 7. And the hole 9 of the center part 3a of the leaf | plate spring 3 is fitted in the annular convex part 5 of the rotation screw holder 2 so that rotation is possible. A part of the surface of the annular convex portion 5 is crushed and spread outward to prevent the leaf spring 3 from coming off.

  The fixing screw 1 is screwed into the screw hole 4 of the rotary screw holder 2 so that both side portions 6 and 6 protrude toward the screw head 1a side.

  Next, an assembling method for assembling a lattice (cross member) formed from the same extruded shape to a column (vertical member) formed from an extruded shape of aluminum using the mounting part A, and this assembling method The constructed structure will be described with reference to an example of a fence.

  In FIG. 3, reference numeral 10 denotes a support column, and 11 denotes a fence grid. The lattice 11 is provided on one side provided only on one side of the column 10.

  As shown in FIGS. 4 and 5, a through hole 12 through which the fixing screw 1 passes is formed in the lattice mounting portion of the support column 10 from the front side to the back side.

  Grooves 13 are formed on the back surface of the lattice 11 along the longitudinal direction thereof. The groove portion 13 has a dovetail shape and is formed wider on the inner side than the opening portion.

  A fixing screw 1 is penetrated from the front side to the back side of the support column 10, and a rotating screw holder 2 is screwed to the front end side of the fixing screw 1 protruding from the back side. The rotating screw holder 2 is housed inside the groove 13, and both ends are engaged with the back side of the opening edge of the groove 13. Further, when the fixing screw 1 is tightened, both side portions 6 and 6 of the leaf spring 3 are folded against the spring force of the bent portion 14 as shown in FIG. ing.

  The width of the rotating screw holder 2 of the mounting part A is formed smaller than the opening width of the groove portion 13 of the lattice 11, and the length of the rotating screw holder 2 is larger than the opening width of the groove portion 13, It is formed to be longer than the width.

  Next, an assembling method when the lattice 11 is assembled to the support column 10 using the mounting part A will be described with reference to FIGS. 7 (a) and 7 (b).

  First, a plurality of support columns 10 are erected on the installation surface, and the fixing screws 1 of the attachment part A are passed through the through holes 12 formed at predetermined positions of these support columns 10, and the tips of the fixing screws 1 protruding from the back surface are provided. The rotating screw holder 2 with a leaf spring is screwed to the side. At this time, the rotating screw holder 2 is kept in a substantially horizontal state. Since the tips of both side portions 6 and 6 of the leaf spring 3 abut against the back surface of the column 10, the fixing screw 1 is always urged and held so as to protrude from the back side of the column 10 by the spring force.

Next, the grid 11 is placed in a horizontal state and pressed against the support 10, and the rotary screw holder 2 protruding from the support 10 is swallowed and stored in the groove 13, and is engaged with the groove 13. Thereby, the lattice 11 is temporarily fixed at a predetermined position of the support column 10. Z
When the grid 11 is pressed against the support column 10 as described above, the back surface of the grid 11 hits the rotary screw holder 2 and presses the rotary screw holder 2 toward the support pillar 10 side, and the fixing screw 1 is pushed in the pulling direction. Even if it is returned, when the pressing force is released by moving the lattice 11 away from the support column 10, the fixing screw 1 is pushed back so that its tip protrudes toward the back side again by the reaction force of the leaf spring 3. It is. Therefore, the operator can proceed with the work of swallowing and storing the rotating screw holder 2 protruding from the support column 10 into the groove portion 13 of the lattice 11 until it succeeds as many times as possible.

  The other parts of the lattice 11 may be fixed in the same manner by fastening the fixing screws 1 to the other columns 10. As the fixing screw 1 is rotated and tightened, the contact friction between the screw shaft portion 1b and the rotating screw holder 2 increases, so that the rotating screw holder 2 eventually rotates together with the fixing screw 1 as shown in FIG. . However, since the length of the rotating screw holder 2 is longer than the inner width of the groove portion 13, the rotating screw holder 2 engages with the upper and lower inner surfaces of the groove portion 13 and cannot rotate any further. Therefore, only the fixing screw 1 is tightened. Accordingly, the leaf spring 3 is also pushed into the support 10 side, so that the side portions 6 and 6 are folded as shown in FIG. Since the recessed part 7 is formed in the front-end | tip part of the both sides 6 and 6, the fixing screw 1 does not interfere with the recessed part 7 when the both sides 6 and 6 of the leaf | plate spring 3 are folded. . Further, since the rotating screw holder 2 is formed in a substantially parallelogram shape, it can be engaged deeply swallowed inside the groove portion 13 without rotating 90 degrees when rotating together. It can be done quickly and efficiently. In addition, although the both side parts 6 and 6 of the leaf | plate spring 3 are folded small after completion | finish of this tightening, since the reaction force by the elasticity is effective, there exists an effect which prevents the leaf | plate spring 3 from loosening. Moreover, since the front-end | tips 6a and 6a of the both sides of the recessed part 7 are bent, it can handle safely.

  In addition, the grating | lattice 11 is not limited to the above single-sided fitting. As shown in FIG. 9 and FIG. 10, the double-sided housing in which the lattices 11 a and 11 b are attached to the opposite surfaces of the column 10 may be used. In this case, one grid 11a may be attached as described above. When the other lattice 11b is attached, the mounting part B shown in FIG. This attachment part B is formed by bending both ends on the short side of the elongated central piece 15 at substantially right angles, and providing four locking pieces 17 on the long side of the central piece 15 in the direction opposite to the bent piece 16. Thus, a protrusion 18 is formed on the front side of the locking piece 17. The central portion of the central piece 15 is fixed to the support column 10 by the head 1a of the fixing screw 1, and the bent piece 16 is held so as not to move by engaging with both sides of the support column 10. Then, the back surface of the other lattice 11 b may be pressed against the mounting part B, and the locking piece 17 may be inserted inside the groove 13 to be locked to the protrusion 18.

  As shown in FIG. 12, the opposing surfaces of the one lattice 11a and the other lattice 11b are preferably reinforced by being connected with a Z-shaped connecting bracket 19 by known means.

  In addition, the cross-sectional shape of the grating | lattice 11 is not limited to the above-mentioned form. For example, as shown in FIG. Further, as shown in FIG. 14, a lattice 11 having different cross-sectional shapes may be used in combination.

  15 and 16 show the form of a cross grating. The two gratings 11c and 11d constituting the cross grating 11 are provided on the opposite sides of the column 10 at the same position. In this case, as shown in FIG. 16, one grid 11c may be attached as described above. When attaching the other lattice 11d, the one piece 20a of the Z-shaped attachment part 20 is fixed to the head of the fixing screw 1. As a result, the other piece 20b floats from the support column 10, and the groove 13 of the other lattice 11d may be locked to the other piece 20b. In addition, the upper end surface of the attachment component 20 is formed in circular arc shape.

  In addition, what is necessary is just to connect and fix the cross | intersection part of the grating | lattice 11 via the Z-shaped connection metal fitting 21, as FIG. 17 shows. Further, it is preferable that the support column 10 and the lattice 11 are also firmly connected and fixed by the L-shaped reinforcing bracket 22.

  The leaf spring 3 described above is not limited to a configuration in which the leaf spring 3 is rotatably attached to the rotary screw holder 2. The structure directly attached to the axial part of the fixing screw 1 may be sufficient.

  The elastic members of the mounting part A described above are all constituted by the leaf springs 3. However, the elastic member is essentially when the rotating screw holder 2 is pressed in the axial direction of the fixing screw 1 and the pressing force is released. In addition, it is sufficient that the fixing screw 1 is elastic enough to push it back to the original position, and is not limited to the leaf spring 3. For example, it may be a coil spring, or may be rubber, sponge or the like.
