[Industrial applications]

 The present invention relates to an improvement of a block iron used for masonry work of concrete blocks, mainly reinforced concrete blocks (book wall blocks and structural blocks).

[0002]

[Prior art]

 In the masonry work of concrete blocks, a block gote is used to put joint material such as mortar on the joint surface between blocks. In the conventional block gote, which is generally used, a bar-shaped wooden handle b is normally provided on an isosceles triangular spatula (i) whose top is simply curved in a plan view as shown in FIG. There is a block iron of No. 2 or a “half cut” having a spatula portion a in a shape obtained by cutting out the right half of the spatula portion a of the normal block iron as shown in FIG. When the worker (block craftsman) actually uses the mortar, the joint material is put in a container such as a bucket in advance, and the block gote held in the right hand is pushed vertically from the tip into the container such as the bucket. Then, trace the right edge of the spatula part a along the inner peripheral surface of the container counterclockwise and scoop the mortar onto the top surface of the spatula part a to transfer the desired amount to the iron plate in your left hand. Then, place the mortar on the iron plate on the left-hand side back surface of the spatula part (i.e., the stacking surface) by pushing the left edge of the spatula part (i) vertically to the iron plate and pushing it forward. ) (2 places on the left and right of the front side of the block, and 2 places on the left and right of the rear side) 4 times in total. Let). To load the mortar into the block cavity, hit the top of the block with the bottom of the handle to drop the mortar placed on the back side of the spatula part a into the cavity from the height direction of the spatula part a. ing.

[Problems to be solved by the device]

 However, since the spatula part (a) is wide, the above-mentioned ordinary block gote is not very convenient because the wide part is an obstacle when scooping mortar from a container such as a bucket. There are also various problems with the half-cut block iron. That is, firstly, since the tip (top) of the spatula portion a is tapered, when the mortar on the iron plate is placed on the back surface of the spatula portion a, the required amount of mortar is not placed on the tip of the spatula portion a. The thickness of the mortar in the corners of the blocks (where the blocks are adjacent to each other) is apt to be insufficient, and it is necessary to perform the joint construction most carefully at important points in terms of preventing rain such as water leakage from the joints. There is a drawback that certain corners of a block are not reliable in terms of stopping rain due to lack of joints. Secondly, the axis of the rod-shaped handle b is not set parallel to the right side of the spatula b and is slightly inclined, so the wrist twists at an unnatural angle when scooping mortar from a container such as a bucket. Increased fatigue on the wrist. Thirdly, when the upper block is laminated on the mortar, it is necessary to hit the upper surface of the block with a piece of wood to adjust the left and right height of the block each time in order to keep the upper surface of the upper block horizontal. However, it is troublesome to change the block iron into pieces such as wood for this adjustment work, and in general it is the fact that the bottom of the handle part b of the block iron is struck instead of wood, so shock and vibration at the time of hitting An unpleasant jarring vibration sound that propagates to the metal spatula b and is repeatedly generated at the ear of the craftsman throughout the day is also a cause of hearing loss.

[0004]

[Means for Solving the Problems]

 The block iron according to the present invention is made based on the above-mentioned actual condition, and of the two left and right sides connected to the bottom, the right side is approximated to the bottom at right angles in plan view, and the upper surface is made of mortar or the like. In the scooping portion of the joint material, the left side is inclined with respect to the bottom side, and the back side closer to the left side is cut out so that the top side of the triangular plate body formed on the joint material mounting portion is substantially parallel to the bottom side. A spatula part having a height of about one half of the block length and a width on the top side of about one quarter of the block thickness was formed, and the spatula part was continuously provided on the top surface of the spatula part. The gist is that the axis of the rod-shaped handle is set to be parallel to the right side, and at the same time, a hammer made of synthetic resin is integrally provided on the rod-shaped handle.

[0005]

[Operation] When scooping mortar from a container such as a bucket with a block iron, the axis of the bar-shaped handle is set to be parallel to the side edge of the scoop provided on the right hand side of the spatula. You can easily scoop up your wrist without unnatural twisting. In addition, when placing the mortar on the iron plate on the upper surface of the block with the block iron, it is possible to place a substantially uniform amount (uniform thickness) of mortar on the placing part provided on the back surface of the spatula on the left hand side. It is possible to easily construct joints of uniform thickness over almost the entire area of the top surface of the block without running out of the amount of mortar in the corners of the block, and to improve rain control.

【Example】

 The structure of the present invention will be described with reference to an embodiment shown in the drawings, in which 1 is a block iron, and the block iron 1 is composed of a spatula portion 2 and a grip portion 3. The spatula portion 2 is formed by cutting out the top side of the metallic triangular plate body substantially parallel to the bottom side 4 (in the illustrated example, the upper right side in the vertical direction) so that the height h is about half the length of the block B. 1, the lateral width w 1 on the top side is set to a dimension of about ¼ of the thickness of the block B. The dimensions of the basic block B for book wall are stipulated by the standard to be 390 mm in length, 190 mm in height, and 100 mm in thickness (some are 150 mm and 190 mm), and joints between adjacent blocks B and B are specified. The thickness is generally 10 mm. By the way, a corner portion on one side (left side) of the spatula portion 2 on the top side is cut off, and a reference portion P for measuring an appropriate mortar thickness is provided in the corner portion. By the way, as shown in FIG. 2, the right side 5 of the two left and right sides 5 and 6 connected to the bottom 4 is approximated to the base 4 at right angles (80 ° to 90 ° is ideal). ), The upper surface of the spatula portion 2 is formed as a scooping portion b when scooping a joint material a such as mortar (hereinafter simply referred to as mortar) a from a container such as a bucket. Further, the left side 6 is inclined at a predetermined angle with respect to the bottom 4 (in this embodiment, it is inclined about 75 ° with respect to the bottom 4), and the back surface near the left side 6 is a mortar on the iron plate. It is formed on the mounting portion c when a is mounted and transferred onto the block. Reference numeral 7 denotes a mounting stay for the grip portion 3, which has a substantially L-shaped side surface, and the base end side is the upper surface of the spatula portion 2 near the bottom side 4 in the direction of the right side 5 from the center of the bottom side 4. The handle portion 3 is fixed to the eccentric position, and the round bar-shaped handle portion 3 is fixed to the tip end side. The axis L of the rod-shaped handle portion 3 is set to be parallel to the right side 5 of the spatula portion 2. Further, a hammer portion 8 made of hard synthetic resin is integrally provided on the tip side (butt side) of the handle portion 3 by screwing or the like. Reference numeral 9 is a cushion material made of an elastic member such as rubber. The entire grip portion 3 may be made of hard synthetic resin. The surface of the handle portion 3 is appropriately provided with an anti-slip process such as a longitudinal groove 10 or a ridge or a knurling process. Reference numeral 11 is a trowel plate, 12 is a container such as a bucket accommodating the mortar a, and 13 is a reinforcing bar to be inserted into the cavity Q of the block B.

During work, hold the block iron 1 with one hand (right hand) and the iron plate 11 with the other hand (left hand), and scoop up the mortar a in the container 12 such as a bucket with the block iron 1 to make the iron plate. Although a predetermined amount is placed on the base 11, when the mortar a is scooped up from the container 12 such as a bucket with the block iron 1, the axis L of the rod-shaped handle 3 is parallel to the right side 5 of the spatula 2. As shown in FIG. 4, when the spatula part 2 is slid counterclockwise along the inner peripheral surface of the container 12, the wrist is not twisted in an unnatural manner and the mortar a is scooped out b. You can easily pick up. Therefore, the degree of fatigue of the wrist can be minimized. Also, when the mortar a on the iron plate 11 is placed on the upper surface of the block B by the block iron 1, the left side 6 of the spatula portion 2 is pressed vertically against the upper surface of the iron plate 11 as shown in FIG. Cut the mortar a on the iron plate 11 into strips from one end side, and push the block iron 1 forward along the upper surface of the iron plate 11 as it is. Since a substantially uniform amount (uniform thickness) of mortar a can be placed over the length, there is no shortage of the mortar amount at the corners of block B, and joints of uniform thickness are made over the entire top surface of block B. Can be easily installed. At this time, by appropriately leveling the mortar a on the iron plate 11 so as to be at the same height as the reference portion P of the spatula portion 2, an appropriate amount of mortar a can always be placed on the upper surface of the block A. As a result, joint construction can be performed easily and reliably. In this way, the mortar a is placed at a total of four places on the upper surface of the block B, two in the front, rear, left, and right (the cavity Q of the block B is also filled with the mortar a), and the upper block B is laminated thereon. After that, while striking the upper surface of the upper block B, the left and right heights are adjusted so that the horizontal surface is flush with the adjacent block B. At this time, since the hammer portion 8 made of a hard synthetic resin is integrally formed on the tip side (butt side) of the handle portion 3, the handle portion 3 is simply replaced without moving the block iron 1 each time. The upper surface of block B can be hit by simply changing the direction, which is extremely convenient and improves work efficiency. In addition, since the hammer part 8 is made of synthetic resin, vibration occurs at the metal spatula part 2 when hitting. It does not propagate and produce annoying noise. This noise damping effect is further enhanced by the cushion rubber.

[0008]

[Effect of device]

 Since the present invention is configured as described above, when scooping mortar from a container such as a bucket with a block iron, the axis of the bar-shaped handle is parallel to the side edge of the scooping part provided on the right hand side of the spatula. Since it is set so that the wrist does not twist unnaturally and can be scooped up easily, fatigue of the wrist can be greatly reduced, and mortar on the iron plate is blocked. When placing it on the top surface of the block with a gote, it is possible to place a substantially uniform amount (uniform thickness) of mortar over the entire length on the left-hand side of the spatula, so the block corners where adjacent blocks connect It is possible to construct joints of uniform thickness easily and reliably over the entire top surface of the block without running out of mortar, and to prevent rain from leaking from the joints after construction and to further improve rain control. It can be a virtuous. In addition, since the hammer part made of synthetic resin is integrally provided on the handle part, the handle part of the block iron is held in the hand without having to switch the block iron each time when adjusting the block horizontally. You can easily adjust the horizontal direction by hitting the top surface of the block by simply changing the direction, which is extremely convenient and improves work efficiency.Because the hammer part is made of synthetic resin, you can hit it like a wooden handle part. At times, shocks and vibrations can be prevented from propagating to the spatula to generate annoying noise, and the structure is simple, but very useful practical effects are achieved.
