Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a block connecting plate used for connecting blocks in a block structure constructed by a dry method. 2. Description of the Related Art Conventionally, block structures have mainly been constructed by stacking concrete blocks with cement, mortar, etc. interposed therebetween. To avoid this, a lightweight block using a synthetic resin, especially a foamed synthetic resin, is used.
Such a block made of synthetic resin foam is laid on soft ground instead of embankment (Japanese Patent Laid-Open No. 5-2 / 1993).
No. 14704), and since the block is lightweight and has good workability, it is also used for a fence constructed on a house exterior or the like. For example, Japanese Unexamined Patent Publication No. Hei 5-321437 discloses a structure in which a block made of a foamed synthetic resin and a tile material is adhered to a surface thereof are installed by a dry method. Conventional block structures using concrete blocks are generally constructed by the so-called wet method, while those using foam synthetic resin blocks are constructed by the dry method. Has the advantage of shortening the construction period. [0003] A block structure constructed by the dry method as described above, for example, a structure constructed as an external wall of a house or the like, has an inter-block structure to prevent collapse. Must be securely connected, and the connection includes
A method of forming a fitting groove on the side surface of the block and connecting the blocks with each other by interposing a frame or the like, or a method of interposing a plate having a pointed claw penetrating the block between the blocks is adopted. ing. However, in the connection between blocks,
In addition to simply connecting the blocks, the two-dimensional load that can be applied to the block, that is, the position of the block is regulated for the load acting in the longitudinal direction and the thickness direction of the block, and the strength of the block structure is increased. It is necessary to maintain. The present invention has been made in view of the above problems, and is directed to a block connecting plate used for a block structure constructed by a dry method for connecting blocks, the plate having a longitudinal direction acting on the block structure. It is an object of the present invention to provide a device that regulates the position of each block with respect to a load in a thickness direction. In the block connecting plate according to the present invention, an insertion hole through which a column for supporting a block is inserted is formed at a predetermined position of the flat plate. A penetrating claw projecting in at least one direction from each of the front and rear surfaces of the plate is formed, and the penetrating claw is wide in the thickness direction of the block in order to regulate the position of the block in the longitudinal direction; And at least two types of penetrating claws with a wide penetrating claw in the longitudinal direction of the block in order to regulate the position in the direction, and interposed between the stacked blocks while being inserted through the column. Then, a pair of blocks sandwiching at least the struts are connected by penetrating the penetrating claws into the end faces of the blocks. [0007] Thus, for example, between the blocks of a block structure in which the blocks are fitted and stacked between a plurality of columns, a block connecting plate from which two types of penetrating claws protrude in the vertical direction is formed on the column. By being inserted and interposed, the penetrating claws penetrate into the upper end surface and the lower end surface of the block, respectively, and can connect the pair of left and right sandwiching the column and the pair of blocks above or below it. In a block structure in which the columns are provided in the horizontal direction, the block connecting plate interposed between the blocks has a pair of upper and lower pairs that sandwich the columns by penetrating claws penetrating into the side end surfaces of each block. Any one of the left and right blocks is connected. Embodiments of the present invention will be described below in detail with reference to the drawings. As shown in FIG. 1, the block connecting plate 100 is provided with strut insertion holes 10 at predetermined positions of a flat plate, and penetrating claws 11, 12 projecting vertically from the front and back surfaces of the plate, respectively.
Is formed. The plate is substantially rectangular and has a width smaller than the thickness of the block to be connected, and has a thickness of, for example, several mm or less, so that a large gap does not occur when interposed between the blocks. The pillar insertion hole 10 has substantially the same shape as the cross section of the pillar to be inserted. For example, when a rectangular steel pipe is used as a pillar of a block structure, the shape of the pillar insertion hole 10 is rectangular. . The position where the column insertion hole 10 is to be provided may be set in consideration of the positional relationship between the column and the block. However, if the blocks constituting the block structure have substantially the same shape, the center of the plate may be used. It is preferable to drill in the vicinity. The penetrating claws 11 project vertically from the front and back surfaces of the plate, and the penetrating claws 12 project vertically from both side edges of the plate. The block connecting plate 100 configured as described above can be manufactured by punching a metal plate or the like into a predetermined shape and then bending it. FIG. 2 is a plan view showing the plate before the penetrating claws 11 and 12 are bent. As shown in FIG. 2, the penetrating claws 11 have a so-called V-shaped acute cut 11a in the plate. There are provided a total of eight rows of four rows at predetermined intervals per side on both sides of the column insertion hole 10, and a cut 11a is provided for each row.
By being formed by bending the part upward or downward,
It protrudes from the front and back surfaces of the plate in the up and down direction, respectively, and becomes pointed claws which are wide in the width direction of the plate. On the other hand, the penetrating claws 12 are each formed with two rectangular flanges 1 formed in the vicinity of both ends of the longitudinal side edge of the plate.
2a is formed by bending upward or downward,
It protrudes from the side edge of the plate in the vertical direction, and becomes a rectangular claw wide in the longitudinal direction of the plate. The shape of the penetrating claws 11 and 12 can be arbitrarily changed. For example, both the penetrating claws 11 and 12 may be pointed claws or rectangular claws. Can be arbitrarily changed. Furthermore, in the block connecting plate 100 according to the present embodiment, the penetrating claws 11 project upward or downward for each row, but it is not necessary that all rows project in the same direction. Instead, for example, it may be arranged to randomly project upward or downward regardless of the row. Further, depending on the position where the block connecting plate 100 is to be provided, for example, the block connecting plate 1 may be provided at the uppermost end of the block structure.
When 00 is provided, the penetrating claws 11 and 12 may be used so as not to protrude both upward and downward, but to protrude only downward. FIG. 3 shows a state in which the block connecting plates 100 are interposed between the stacked blocks 3. The block connecting plates 100 are fitted to the columns 2 as shown in the figure. In the block structure 1 in which the blocks 3 are stacked in this manner, the columns 2 are inserted into the column insertion holes 10, and are interposed between the stacked blocks 3 so that the blocks located above and below the blocks 3. The penetrating claws 11 and 12 respectively penetrate into the upper end surface and the lower end surface of the block 3, so that the penetrating claws 11 regulate the position of each block 3 in the longitudinal direction. , And a pair of left and right blocks sandwiching the support column 2 and a pair of four blocks 3 above or below the pair are connected. The blocks which can be connected by the block connecting plate 100 are made of a foamed synthetic resin such as expanded polystyrene or expanded polyethylene, and a wall material such as a tile, a stone or a mortar is adhered to the surface of a block base made of the expanded synthetic resin. In any case, the foamed synthetic resin portion is easily deformed to such an extent that the penetration claws 11 and 12 of the block connecting plate 100 can penetrate. Hereinafter, an example of use of the block connecting plate 100 in the block structure 1 constructed by the dry method will be described. As shown in FIG. 4, the block structure 1 has a rectangular tubular support 2 fixed to a base 4 by bolts, and is erected. In the ground on which the block structure 1 is to be constructed,
The base 4 is buried so that the columns 2 protrude from the ground surface, and the blocks 3 are stacked between the columns 2. The block 3 is formed by attaching wall materials 31 to the front and back surfaces of a block base 30 made of a foamed synthetic resin, respectively, and forming concave fitting portions 30 a on both side surfaces of the block base 30. The blocks 3 are stacked so that the fitting portions 30a are fitted to the columns 2. After the lower block 3 is fitted to the column 2, the block connecting plate 100 is externally fitted to the column 2, and the penetration claws 11, 12 penetrate into the upper surface of the block base 30 of the lower block 3. . Since the block base 30 is made of an easily deformable synthetic foam resin, the penetrating claws 11 and 12 can easily penetrate the block base 30 by pressing the block connecting plate 100 by hand or tapping lightly with a hammer or the like. be able to. Subsequently, the blocks 3 are stacked, and the penetration claws 11 and 12 of the block connecting plate 100 penetrate into the lower surface of the block base 30 of the block 3. As in the above, the penetrating claws 11 and 12 can be easily penetrated into the block base 30 by pressing the block 3 by hand or by tapping lightly with a hammer or the like. As a result, as shown in FIG.
Blocks 3 are connected. By repeating this, the blocks 3 are stacked up to the required height, and the block connecting plate 100 is, as shown by a dashed-dotted circle in FIG. The blocks 3 of the block structure 1 can be connected by interposing at least each of the blocks 3. Of course, for example, for each of the columns 2 and for each of the layers of the block 3, a block connecting plate 100 is interposed,
By increasing the number of the block connecting plates 100, the connecting force between the blocks 3 can be further strengthened. A block having a different shape at a side end or a corner of the block structure 1, for example, as shown in FIG.
When connecting the block 3A provided at the side end, the block 3B bent at the corner, or the like, the pillars 3A and 3B are provided in accordance with the longitudinal dimensions of the blocks 3A and 3B, as in the block connecting plate 100A. What is necessary is just to make the one end side short with respect to the insertion hole 10. Further, in this embodiment, an example is shown in which the block connecting plate 100 is used for a block structure constructed on an external structure of a house or the like. For example, the block connecting plate 100 is laid on the ground instead of the embankment. Naturally, it can be used in other block structures such as those. According to the block connecting plate of the present invention, the column is fixed to the column by inserting the column into the column insertion hole, and is interposed between the stacked blocks. Two types of penetrating claws penetrate into the end faces of the blocks sandwiching the support, respectively, to regulate the position of each block in the two-dimensional direction and to connect the blocks. Thereby, a high-strength block structure can be obtained.
