2. Description of the Related Art The present applicant has already proposed a ruler for stacking blocks as described in Japanese Patent No. 2881574. The ruler for block stacking includes a pair of ruler bodies for partially intervening between blocks to be stacked to secure a predetermined joint gap, and a square rod-shaped tie rod penetrating therethrough to connect the ruler bodies. And a tightening screw member to be screwed to the tie rod, and a backing plate fixed to each ruler body so as to be position-adjustable and applied to the block surface for positioning.

[Problems to be solved by the invention]

However, in this conventional ruler for stacking blocks, male threads are provided at both ends of the tie rod, and thumb screws are screwed into each of the male threads on both sides as fastening screw members. The distance between the pair of ruler bodies is adjusted by the thumb screw, and the block is tightened. Therefore, the thumb screw has to be turned many times at both ends of the tie rod, and the adjustment of the interval between the pair of ruler bodies and the tightening work of the block are very troublesome.

Further, a convex portion is integrally formed on the upper and lower surfaces of the pair of ruler bodies, so that a joint gap between upper and lower blocks is secured by the ruler body itself, and a joint gap between left and right blocks is formed by the upper and lower convex portions. When stacking the blocks, place the blocks between the ruler bodies connected by tie rods, sandwich them, and lift the ruler bodies with lifting tools while supporting the blocks from below with the ruler bodies. It was not possible to adopt the usage form of lifting the block. That is, even if the block is sandwiched by the ruler body, it can be used only for the purpose of securing the joint gap, and cannot be used as a carrier for lifting and carrying the block.

SUMMARY OF THE INVENTION The present invention improves a conventional ruler for stacking blocks so that the distance between a pair of ruler bodies can be adjusted and the block can be tightened easily and quickly. It is also intended to be able to be used.

[0010]

Next, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 shows the overall structure of a block stacking ruler A according to the present invention, and FIG. 3 and 4 show cross sections. One unit of the block stacking ruler A includes a pair of ruler bodies 1, a square rod-shaped (cross-sectionally rectangular) tie rod 2 connecting them, and a position of one ruler body 1 with respect to the tie rod 2. A stopper plate 3, a thumb screw 4, which is a fastening screw member for tightening the other ruler main body 1, and a flat L-shaped ruler plate 5, and are usually formed by using two units as shown in FIG. 5. Stack B one by one.

Each ruler body 1 is integrally formed by aluminum die casting. Each ruler main body 1 is a planar rectangular hexahedron as a whole, but has a plate-shaped spacer convex portion 1a having a constant thickness at one end center.
Is interposed between the upper and lower blocks B and B ′ to determine the joint gap in the vertical direction. The ruler body 1 itself will be described with the projecting side of the spacer projection 1a as the front side.

The ruler body 1 forms the spacer convex portion 1a without the upper and lower portions of the front side of the hexahedron so that the block B can be placed with a larger area including the upper surface of the spacer convex portion 1a. In doing so, since the upper part is largely lacked more than the lower part, the upper and lower steps 1b and 1c are staggered back and forth, and the upper step 1b is closer to the center than the lower step 1c.

Therefore, in the ruler body 1, the area of the upper surface 1d is smaller than that of the lower surface 1e except for the missing part. Guide grooves 6a and 6b are formed on the upper surface 1d and the lower surface 1e, respectively. The upper guide groove 6a has a horizontal portion of the upper backing plate 7 and the lower guide groove 6b has a horizontal portion of the lower backing plate 8, respectively. It is fitted so that it can slide back and forth. The upper backing plate 7 and the lower backing plate 8 screw setscrews 9 and 10 into the screw holes 1f in the upper surface 1d and the lower surface 1e of the ruler body 1 through the long holes 7a and 8a provided in the respective horizontal portions. Thereby, it can be individually fixed to the ruler body 1 so that the front and rear positions can be adjusted. Also, the upper backing plate 7
And the lower backing plate 8 can be replaced by removing the set screws 9 and 10, respectively.

The upper backing plate 7 is L-shaped and the upper part 7b of the vertical part is bent backward, while the lower backing plate 8 is inverted L-shaped and the lower part 8b of the vertical part is bent. It is bent rearward. The horizontal portion of the upper backing plate 7 fitted in the upper guide groove 6a is flush with the upper surface 1d of the ruler body 1, and the lower backing plate 8 fitted in the lower guide groove 6b.
Is flush with the lower surface 1e of the ruler body 1. The upper backing plate 7 and the lower backing plate 8 can be shared by producing substantially the same one and turning it upside down when attaching to the ruler body 1.

The ruler body 1 penetrates back and forth along its center line, that is, from the center of the rear end face to the spacer protrusion 1a.
A rod through hole 11 having a rectangular cross section penetrating to the center of the tip of the tie rod 2 is provided, and the tie rod 2 can be slidably penetrated (rotation is impossible) through the rod through hole 11.

Each ruler body 1 has an arched suspension member 1
2 is rotatably mounted by pivotally supporting the lower ends of the left and right legs to the center of the right and left side surfaces of the ruler body 1 with left and right bolts 13. The bolt 13 is screwed into a screw hole 1g provided in the center of the right and left side surfaces of the ruler body 1, but has a shaft portion without a screw in the middle between the head portion and the male screw portion. , The suspension member 12 is pivotally supported.

The hanging member 12 is made of a metal long plate as a whole.
It is bent into a letter shape, and the bent central portion is drawn into a U-shaped cross section to be rounded. Such rounding makes it easier to hang a hand or a hanging string and increases the strength of the hanging member 12 itself.

In the middle part of the left and right legs of the suspension member 12, a slightly elongated hole 14 is provided for allowing the handle 5a of the ruler plate 5 to be freely inserted and removed, and the ruler plate 5 has the handle 5a as described above. The handle portion 5a is located slightly above the upper backing plate 7 by being detachable from the hanging member 12.

The ruler plate 5 has a spacer portion 5b at the tip of the handle portion 5a, and a joint gap between left and right adjacent blocks is secured by the spacer portion 5b. At that time, the suspension member 12
Is rotated slightly forward as shown in FIG.
By contacting the handle 5a with the upper surface 1d of the ruler body 1 and the upper surface of the horizontal portion of the upper backing plate 7, the movement of the ruler plate 5 with respect to the suspending member 12 can be regulated and the ruler plate 5 can be fixed on the ruler body 1. ing.

The tie rod 2 has a male screw portion 2a only at one end thereof, and the other end portion remains a rectangular cross section. At one end of the tie rod 2, a screw member for tightening the male screw portion 2a is provided. The thumb screw 4 is screwed in, but the stopper plate piece 3 is fitted to the other end, which is still square in cross section.

As shown in FIG. 2, the stopper plate 3 is shaped like a washer, and has a tie rod 2 having a rectangular cross section.
Is formed in the center, and both sides are bent in the shape of a letter to the opposite side around the square hole 15 to form a symmetrical bent portion 3a.

The ruler body 1 itself can slide on the tie rod 2, and the stopper plate 3 itself can slide on the tie rod 2 by fitting its square hole 15 into the tie rod 2. However, since the stopper plate 3 is partially bent and the tie rod 2 has a rectangular cross section, the rear end face of the ruler body 1 abuts on the bent portion 3a of the stopper plate 3 as shown in FIG. Then, the stopper plate 3
, The sliding of the stopper plate 3 against the tie rod 2 is restricted. Therefore, the ruler main body 1 whose rear end surface is in contact with the bent portion 3a of the stopper plate 3 is further restricted by the stopper plate 3 from sliding.

Therefore, as shown in FIG. 6, the stopper plate 3 is slid with respect to the tie rod 2 to an arbitrary position, and then the ruler body 1 on one side is slid with respect to the tie rod 2 so that the ruler body 1 is moved. The rear end surface of the tie rod 2 is brought into contact with the bent portion 3a of the stopper plate piece 3 to restrict the sliding of the ruler body 1 on one side.
When the thumb screw 4 is screwed forward with respect to a, the ruler bodies 1 on both sides
The block B can be clamped and held by the upper backing plate 7, and the operation can be performed easily and quickly.

The bent portion 3a of the stopper plate 3 can be used only on one side, but if it is formed on both sides, when the square hole 15 is fitted to the tie rod 2, the direction of the front and back of the stopper plate 3 is determined. It is not necessary.

Next, an example of use of the block stacking ruler of this embodiment will be described. As shown in FIG. 5, in order to stack one block B on the already installed block B ′, two units of the block stacking ruler A are used, and the distance between the ruler main bodies 1 on both sides of each unit is set to the distance of the block B. After being adjusted as described above in accordance with the size, the block B is placed on the spacer projections 1a of the ruler body 1 on both sides of the two units, and the thumb screw 4 is screwed forward in each unit, and the rulers on both sides are rotated. The block B is clamped and held by the upper backing plate 7 of the main body 1.

If the two units are simultaneously lifted by hanging a hanging string or the like on the hanging members 12 of the ruler body 1 on both sides of each unit, the block B can be lifted. If it is stacked on the block B 'installed as it is, the spacer protrusions 1a of the four ruler bodies 1 are located between these upper and lower blocks B.
, The joint gap in the vertical direction of the upper and lower blocks B is automatically secured by the spacer convex portion 1a.

In order to align the position of the newly stacked blocks B in the front-back direction with respect to the already installed block B ', the lower backing plate 8 is used, and the front-back position is adjusted with respect to the ruler body 1. Then, the vertical portion of the lower backing plate 8 is brought into contact with the front surface or the rear surface of the lower block. Since the upper and lower backing plates 7 and 8 can be individually adjusted in the front-rear position with respect to the ruler main body 1, it is possible to easily cope with a difference in block shape.

Further, a ruler plate 5 is used to secure a joint gap between left and right adjacent blocks having the same height. In this case, the spacer portion 5b of the ruler plate 5 is brought into contact with the left or right end surface of the block B clamped and held as described above, and in order to maintain this contact state, the suspension member 12 is rotated slightly forward. The handle 5a of the ruler plate 5 is placed on the ruler body 1 as described above. In this state, the block B is lifted as described above, and the spacer portion 5b of the ruler plate 5 is lifted.
Is brought into contact with the end face of the already-installed block B 'having the same height, and the new block B is lifted up.
Are stacked on the block B 'already installed as described above. Thereby, the spacer portion 5b of the ruler plate 5 is interposed between the end surfaces of the blocks BB, B 'adjacent to each other on the left and right, and the joint gap therebetween is automatically secured.

The ruler plate 5 is a new block B
Until they are stacked on the already installed block B ', they are detached from the suspending member 12, and even if they are mounted on the suspending member 12 after being stacked, the joints between the blocks adjacent to the left and right by the spacer portion 5b. A gap can be secured.

If the ruler body 1 is used where the joint gap between the blocks intersects crosswise in the left, right, up and down directions, the ruler plate 5 cannot be used. Use the installed backing plate. That is, in addition to the above-mentioned upper backing plate 7 and lower backing plate 8 without a protrusion, as shown in FIGS. A lower backing plate 8 'having a protruding member 17 is prepared in advance, and is replaced and attached to the ruler main body 1. The protruding members 16 and 17 are interposed between adjacent blocks on the left and right sides, and a space between them is provided. Secure joint gaps.

As the projections 16 and 17, for example, bolts having a circular head are used, and an upper backing plate 7 'and a lower backing plate 8' are used.
When the male screw portion is passed through the hole 18 provided in the vertical portion and tightened with the nut 19, it can be easily fixed to the upper backing plate 7 and the lower backing plate 8, and the holes 18 are provided as the upper backing plate and the lower backing plate. If these are manufactured, they can be commonly used with and without the protrusions 16 and 17.
