The upper-side metal fitting 17 protrudes integrally from both ends at a right angle downward, and is guided by being inserted into guide grooves 19 and 19 provided on both sides of the horizontal plate portion 5 of the plate body 7 with the long groove 12 interposed therebetween. The guide part pieces 17a and 17a are formed in a downward U-shaped frame shape including both guide part pieces 17a and 17a. The lower-side metal fitting 18 has a substantially upward U-shaped frame shape composed of a lower piece 18a, both side pieces 18b, 18b, and lip pieces n, n projecting inward at right angles from the upper ends of the both side pieces 18b, 18b. Therefore, each side piece 18b of the lower side metal fitting 18 and the guide part piece 17a of the upper side metal fitting 17 are integrally connected and fixed by a connecting member 20 made of a bolt. Since the lip pieces n of the lower metal fitting 18 slide smoothly in a surface contact state with the lower surface 5b of the horizontal plate portion 5 when the slide metal fitting 10 is slid, the sliding operation becomes easy and the plate body 7 Even when the horizontal plate portion 5 is made of a relatively thin metal plate, the horizontal plate portion 5 is not damaged. Further, although there may be only one connecting member 20 composed of a bolt for connecting each side piece 18b of the lower side metal fitting 18 and the guide part piece 17a of the upper side metal piece 17, 2 each of them as shown in FIG. 5 (b). If connected with a book, the upper metal fitting 17 and the lower metal fitting 18 can be firmly connected and fixed. In this way, the upper metal fitting 17 and the lower metal fitting 18 are firmly connected and fixed, and the lip pieces n, n of the lower metal fitting 18 are slid in surface contact with the lower surface 5b of the horizontal plate portion 5. By doing so, the slide fitting 10 composed of the guide pin 13, the pair of lock pins 15, 15 on both sides, the upper metal fitting 17 and the lower metal fitting 18 can be held in a vertical posture, and the sliding property of the slide metal fitting 10 becomes good, and the lock The pin 15 can be accurately locked and unlocked.

  The support metal 11 is supported by the lower metal fitting 18 so as to be movable up and down, and a coil spring 16 is interposed between the lower metal fitting 18 and the support metal 11. That is, the support metal fitting 11 includes a metal fitting body 21 formed in a smaller downward U-shaped frame shape than the upper metal frame-shaped lower metal fitting 18 and a metal fitting so as to protrude vertically downward from the top of the metal fitting body 21. The support shaft 22 is integrally attached to the main body 21, and the support shaft 22 is inserted through a hole 23 penetrating in the center of the lower piece 18 a of the lower side metal fitting 18 so as to be movable up and down. Due to the coil spring 16 interposed between the support shaft 22 and the lower piece 18a of the lower metal fitting 18, the upper surface of the metal fitting body 21 of the support metal fitting 11 is placed on the horizontal plate portion 5 as shown in FIG. It is urged upward so as to abut on the lower surface 5b. 4 and 5, reference numeral 24 denotes a fixing pin for fixing the upper end of the coil spring 16 fitted to the support shaft 22 to a predetermined position, and reference numeral 25 denotes a support for preventing the lower side metal fitting 18 from coming out of the support shaft 22 during assembly. A stopper pin inserted into the lower end of the shaft 22.

  The locking guide pin 13 is fixed to the top of the downward U-shaped frame-shaped support fitting 11 so as to be coaxial with the support shaft 22 and project vertically upward, and this downward U-shaped frame-shaped support is supported. Base ends 15o, 15o of a pair of L-shaped lock pins 15, 15 engaged with lock holes 14, 14 on both sides of the long groove 12 are fixed to both sides of the metal fitting 11, respectively. The base end portions 15o and 15o of the pins 15 and 15 are slidable in the vertically long guide grooves 26 and 26 provided on both side pieces 18b and 18b of the lower side metal fitting 18, as can be seen from FIG. Insertion is supported. Each guide groove 26 has a role of guiding each lock pin 15 when unlocking each lock pin 15, preventing rotation of the support fitting 11, and maintaining the posture of the lock pin 15. As can be seen from FIG. 5 (b), each guide groove 26 extends to the lip piece n on the upper end side of the side piece 18b of the lower side metal fitting 18, and is thus opened. By using the groove, the support metal fitting 11 can be easily assembled into the lower metal fitting 18.

  As shown in FIGS. 4 and 5, a guide pin pressing opening 27 is provided in a portion corresponding to the long groove 12 of the horizontal plate portion 5 in the upper metal fitting 17 of the slide metal fitting 10. As will be described later, the opening 27 pushes down the locking guide pin 13 and unlocks the locking pin 15, as shown by the phantom line in FIG. 4 (b). It is formed in an oval size (see FIG. 5A) that can be inserted. In this case, when the fingertip portion of the index finger 29 is inserted into the opening 27 and the head of the locking guide pin 13 is pressed from above, the guide pin 13 is pushed down and the lock pins 15 and 15 are locked into the lock holes 14 and 14. The locking guide pin 13 is unlocked and the head of the locking guide pin 13 remains engaged with the long groove 12 as shown in FIG. The slide metal fitting 10 can be slid along the horizontal plate portion 5 of the plate body 7 by holding the upper metal piece 17 and moving it left and right. Further, the upper metal fitting 17 of the slide metal fitting 10 is slightly more than the lock hole 14 for allowing the upper end portion of the lock pin 15 protruding upward from the lock hole 14 to enter the portion corresponding to the lock hole 14 of the horizontal plate portion 5. A large-diameter through hole 28 is provided. The through hole 28 is also a hole for confirming whether or not the lock pin 15 is engaged with the lock hole 14 of the horizontal plate portion 5.

  4 (a) and 5 (a) and 5 (b), the locking guide pin 13 protrudes upward from the long groove 12 of the horizontal plate portion 5 and enters the opening 27 of the upper metal member 17 and both. The lock pins 15, 15 are engaged with the two lock holes 14, 14 of the horizontal plate portion 5 to show the lock means 9 in a locked state. 4 is pushed down with a finger against the urging force of the coil spring 16, the support fitting 11 is moved downward as shown in FIG. 4 (b), and the lock pins 15 and 15 on both sides integral with the support fitting 11 are moved. The slide plate 10 is released from the lock holes 14, 14 of the horizontal flat plate portion 5 and is unlocked. In this unlocked state, the slide fitting 10 is guided by the lock guide pins 13 engaged with the long grooves 12 of the horizontal plate portion 5. While, along the horizontal plate part 5 of the plate body 7 It can slide in the width direction. In this unlocked state, when the lock pin 15 is released from the lock guide pin 13 at a position facing the lock hole 14 of the horizontal plate portion 5, it is automatically locked. That is, the support metal 11 is lifted by the urging force of the coil spring 16, and the lock pins 15 and 15 are engaged with the two lock holes 14 and 14 to be locked.

  In using the scaffold plate gap plate 1 configured as described above, as shown in FIG. 9, it was bridged between the horizontal members 3 and 2 of the scaffolding frames 2 and 2 facing in the length direction of the scaffold plate. A gap generated at the side edge of the scaffolding plate 4 (the lower edge in FIG. 9A) or in parallel between the horizontal members 3 and 3 of the building frames 2 and 2 as shown in FIG. The scaffolding plate gap plate 1 is attached so as to close the gap formed between the two scaffolding plates 4 and 4 (the center side in the drawing of FIG. 10 (a)). When the scaffold plate gap plate 1 is attached, the locking hooks 8, 8 protruding from both ends of the side frame portion 6 from the state in which the plate body 7 is positioned above the gap are attached to both scaffold building frames 2. The horizontal plate members 3 and 3 are engaged with each other, and the front end portion 5o of the horizontal plate portion 5 is placed on the upper surface of the side end portion of the scaffold plate 4.

  6 to 8 show the operation of the locking means 9 in the usage mode of FIG. 9, and FIG. 6 shows a state in which the plate body 7 in the gap closing position is unlocked by the locking means 9. That is, when the plate main body 7 in the gap closing position is unlocked by the locking means 9, the lock pins 16 are arranged in two rows on the horizontal plate portion 5 of the plate main body 7 as shown in FIG. Among the plurality of lock holes 14 provided, the lock hole 14 is engaged with the lock hole 14 at the left end in the figure (the lock hole 14 farthest from the side end portion 4a of the scaffold plate 4), and the slide fitting 10 is the same. As shown in (b) of the figure, the plate body 7 is located farthest from the side end portion 4a of the scaffold plate 4, and the plate body 7 may be displaced in the width direction (right direction in FIG. 6).

  Therefore, it is necessary to lock the plate body 7 at the gap closing position by the locking means 9. For this purpose, first, the locking means 9 itself is changed from the locked state shown in FIG. 4 (a) to the unlocked state shown in FIG. 4 (b). That is, from the locked state shown in FIG. 4A, when the index guide 29 is inserted into the opening 27 of the upper metal member 17 and the locking guide pin 13 is pressed from above, for example, as shown in FIG. Since the guide pin 13 is pushed down and the lock pins 15 and 15 are released from the lock holes 14 and 14 and are unlocked, the abdomen (back surface) of the finger is held on the horizontal plate portion while holding the head of the guide pin 13 with the finger. 5 While sliding along the upper surface, by grabbing the slide fitting 10 and moving it toward the side end 4a of the scaffold plate 4, the slide fitting 10 is guided by the locking guide pin 13 engaged with the long groove 12, Slide along the horizontal plate portion 5 of the plate body 7. 7A and 7B show a state in which the slide fitting 10 is moved in a direction approaching the side end portion 4a of the scaffold plate 4 with the lock pins 15 and 15 unlocked as described above.

  8 (a) and 8 (b) show that the slide metal fitting 10 that is slid in a state in which the lock pins 15 and 15 are unlocked by pressing the head portion of the lock guide pin 13 by hand as described above is a scaffold plate. 4 when the lock pins 15 and 15 are positioned in the corresponding lock holes 14 and 14 of the horizontal plate portion 5 in such a close state. When the hand is released, as shown in FIG. 4 (a), the support fitting 11 is lifted by the urging force of the coil spring 16, and both lock pins 15 and 15 are engaged with the two lock holes 14 and 14, respectively. Locked. Thereby, the plate body 7 is locked at the gap closing position as shown in the figure.

  When the slide fitting 10 is locked at the gap closing position by the lock means 9, the slide fitting 10 is slid in the unlocked state and brought into contact with the side end portion 4a of the scaffold plate 4 and locked at the contact position. Since the pin 15 does not always fit into the lock hole 14, the lock guide 15 is moved back to the near side after being brought into contact with the lock 15 at a position corresponding to the lock hole 14. If the hand is released from the pin 13, the lock pin 15 can be engaged with the lock hole 14 more quickly.

  In order to release the locked state from the state where the plate body 7 is locked at the gap closing position by the locking means 9 as described above, the locking guide pin 13 is moved against the urging force of the coil spring 16 as shown in FIG. As indicated by the phantom line (b), the guide pin 13 is pushed down simply by pressing it from above with a finger, and the lock pins 15 and 15 are released from the lock holes 14 and 14 and unlocked. Then, while holding the head portion of the guide pin 13, the slide fitting 10 is grasped and moved away from the side end portion 4 a of the scaffold plate 4, and the plate body 7 is lifted in this state, whereby the scaffold plate gap The plate 1 can be removed.

  According to the scaffold plate gap plate 1 as described above, the slide fitting 10 is moved to a predetermined position, and the plate body 7 is fixed by the lock means 9, so the difference in the width of the scaffolding frame for the scaffold Corresponding to the difference in gap width due to, the gap when the scaffolding plate 4 is moved to one side along the horizontal frame of the scaffolding frame, or when it is swung away from both sides, it has a sufficient anti-displacement function It can be demonstrated.

  Further, according to the locking means 9 of the scaffold plate gap plate 1, the bolts are tightened as in the conventional scaffold plate gap plate to lock the plate body 7 at the gap closing position of the scaffold plate 4 and to unlock the plate body 7. A troublesome operation of loosening or loosening is unnecessary, and an operation tool is unnecessary. That is, when the plate body 7 is locked at the gap closing position of the scaffold plate 4, the lock pins 15 and 15 are pulled downward from the lock holes 14 and 14 by pressing the head of the locking guide pin 13 by hand. Since the guide pin 13 itself can be engaged with the long groove 12 while being unlocked, the slide fitting 10 is gripped by the slide fitting 10 in this state so as to approach the side end 4a of the scaffold plate 4. By sliding and releasing the hand from the locking guide pin 13 at a required position in contact with or close to the side end portion 4a, the locking pins 15 and 15 are engaged with the locking holes 14 and 14 so that the plate body 7 is separated from the gap.
