Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a mortar support for use in laying concrete blocks to construct a wall.

(Prior Art) As a concrete block, as shown in FIG. 4, it is formed in a horizontally long rectangular parallelepiped shape and has longitudinal grooves 2 for inserting vertical stripes at both ends in the longitudinal direction and a longitudinal groove at the center in the longitudinal direction. A central vertical hole 3 for inserting muscles and a horizontal groove 4 for inserting horizontal muscles are provided on the upper surface to enable staggered stacking, and when the piles are piled, the legs of the fence are inserted into the central vertical holes 3 above. A concrete block 1 that has been made is known. The vertical groove 2 is
It has a shape in which the vertical hole 3 is divided into two vertically, and when two concrete blocks 1 are arranged side by side, two vertical grooves 2 are formed in the adjacent portion, and the adjacent portion has substantially the same shape as the central vertical hole 3. The vertical hole 2A is formed.

When the concrete blocks 1 are stacked in a zigzag manner, the length of one of the concrete blocks 1 is used as a unit pitch, and the central vertical hole 3 or the adjacent vertical hole 2A composed of two vertical grooves 2 in the adjacent portion is used. The vertical streak 5 is arranged, and the horizontal streak 6 is arranged in the horizontal groove 4 at every other stage, and the horizontal streak 6 is opened below the horizontal groove 4 in which the horizontal streak 6 is inserted in the central vertical hole 3 and the adjacent vertical hole 2A. In addition, in the upper end opening 7 of the central vertical hole 3 or the adjacent vertical hole 2A into which the vertical streak 5 is not inserted, the horizontal stirrup 6 thereabove is wrapped with concrete mortar 8 so as to close the upper end opening 7, and then the vertical streak is formed. Central vertical hole 3 in which 5 is inserted, adjacent vertical hole 2A
Further, the concrete mortar 9 was filled in each of the lateral grooves 4 into which the horizontal bars 6 were inserted. Further, during the potato stacking, the same processing was performed in the vertical holes 3 and 2A in which the legs of the fence are not inserted.

(Problems to be solved by the invention) However, the horizontal stirrup 6 above the upper end opening 7 of the central vertical hole 3 or the adjacent vertical hole 2A in which the vertical streak 5 is not inserted is wrapped with concrete mortar 8 and the upper end opening The work of closing 7 is troublesome and requires skill, and since there is no support for the lower side of the concrete mortar 8, there is a problem that the concrete mortar 8 falls off and the horizontal bar 6 is exposed. .

This invention is a concrete mortar 8 produced when the above concrete blocks 1 are stacked in a zigzag or potatoes.
It provides mortar support to prevent the falling of the mortar.

(Means for Solving the Problem) The mortar support 10 (see FIG. 1) of the present invention is fitted into the lateral groove 4 so as to close the upper end opening 7 of the central vertical hole 3 of the concrete block 1. Gutter 11
And the central vertical hole 3 protruding downward from the lower surface thereof.
And a lower surface convex portion 12 that fits in The mortar support 10 can be placed so as to close the central vertical hole 3 of the concrete block 1 to be used, and may be shorter than the length of the concrete block 1.

(Operation) Adjacent vertical holes formed by stacking the above concrete blocks 1 and forming a central vertical hole 3, a horizontal groove 4 and two vertical grooves 2 and 2 between two adjacent concrete blocks 1 and 1 Of the 2A, when the concrete mortar 9 is filled into the central vertical hole 3 in which the vertical line 5 is inserted, the adjacent vertical hole 2A and the horizontal groove 4 in which the horizontal line 6 is inserted, respectively, the central vertical hole 3 and the adjacent part are filled. Of the vertical holes 2A, a horizontal groove 4 that opens below the horizontal groove 4 in which the horizontal streak 6 is inserted and surrounds the upper end opening 7 of the central vertical hole 3 or the adjacent vertical hole 2A in which the vertical streak 5 is not inserted.
Place the mortar support 10 of this invention on the inner surface (3rd
(Refer to the drawing), when the lower surface convex portion 12 is fitted into the central vertical hole 3 or the adjacent vertical hole 2A and the concrete mortar 9 is poured, the horizontal groove 4 in which the horizontal bar 6 is arranged and the vertical groove 3 in which the vertical bar 5 is arranged. 2A is filled with concrete mortar 9,
The concrete mortar 9 does not flow into the central vertical hole 3 and the adjacent vertical hole 2A below the portion where the mortar support 10 of the present invention is placed, and the concrete mortar wrapping the horizontal streaks 4 is the central vertical hole 3 and It is prevented from falling into the adjacent vertical hole 2A, so that the horizontal streaks 4 are not exposed.

(Embodiment) A mortar support 10 shown in FIG. 1 is a synthetic resin molded product, and has a gutter-shaped portion 11 having a U-shaped or V-shaped cross section, and a box-shaped lower surface convex portion 12 protruding downward from the center of the lower surface thereof. And a weir plate-shaped horizontal bar support plate projecting from the groove bottoms at both ends of the gutter-shaped portion 11.
It has 13 and. The above-mentioned gutter-shaped portion 11 has a length that covers the central vertical hole 3 of the concrete block 1 as shown in FIG. 2 and a shape that fits in the lateral groove 4 of the concrete block 1 as shown in FIG. have. Also,
The lower surface convex portion 12 is formed in a size that allows the mortar support 10 to be loosely fitted into the central vertical hole 3 so that the mortar support 10 is not displaced with respect to the concrete block 1. In addition, the horizontal support plate 13 is
The position of the horizontal stripes 6 is set, and a recess 14 is formed at a desired depth on the upper edge. However, this horizontal bar support plate 13
It can be omitted.

In the above structure, when the concrete blocks 1 having the central longitudinal holes 3 and the horizontal grooves 4 for inserting the horizontal streaks in addition to the vertical grooves 2 for inserting the vertical streaks at both ends are stacked in a staggered manner, the length of the concrete block 1 is set as a unit pitch. As shown in FIG. 2, the vertical stirrup 5 is arranged as well as the horizontal stirrup 6 is arranged in every two steps of the concrete block 1, and as shown in FIG. The above-mentioned mortar support 10 was placed on the upper end opening 7, and concrete mortar was filled in each step to obtain a block wall in which the concrete mortar did not fall off.

In addition, the horizontal groove 4 of the concrete block 1 in the lower stage of FIG.
When arranging the horizontal streaks 6 on the mortar support 10, the mortar support 10 is placed on the upper end opening 7 of the adjacent vertical hole 2A.

(Effects of the Invention) Since the mortar support of the present invention has the gutter-shaped portion that fits into the lateral groove of the concrete block, when the concrete block having the central vertical hole is assembled, the upper end opening of the central vertical hole, or 2 By placing the mortar support of this invention at the upper end opening of the adjacent vertical hole formed by the vertical grooves of both concrete blocks, the concrete mortar will flow into the vertical hole without vertical streaks. In addition, the horizontal streaks arranged above the vertical holes can be completely wrapped with concrete mortar, the concrete mortar enclosing the horizontal streaks does not fall off, and the horizontal streaks are prevented from being exposed. Further, since the lower surface convex portion is provided so as to project downward on the trough-shaped portion, the positional deviation when mounted on the upper end opening of the vertical hole is prevented. In addition, as shown in the embodiment, when the horizontal reinforcing plate is projected on both ends of the gutter-shaped portion in the shape of a dam plate, the positioning of the horizontal reinforcing lines becomes easy.
