DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to FIGS. FIG. 1 is an explanatory view in the case of constructing a pillar using a frame building block, wherein 5 is a frame building block, 5a is an upper surface of the frame building block, and 5b.
Is the positioning recess, 5c is the lower surface of the frame construction block,
5d is a positioning convex portion, 5e is a connecting concave portion, 5f is a female screw, 5g is an outer surface of a frame building block, 5h is a hole, 6 is a plate as a connecting member, 7 is a bolt, and 8 is a frame building. The frame 9 formed by the block 5 indicates a space inside the frame 8.

The frame building block 5 is made of a material such as concrete, which can be the outer surface of the post-construction pillar, and is prepared in advance at a factory, and its dimensions correspond to the outer peripheral portion of the pillar.
When the frame-building block 5 is of a size that can be carried by hand, for example, the thickness is 100 mm, and the height is 100 mm.
The U-shape is 200 mm long, 500 mm long, 250 mm short, and weighs 25 kg.

The U-shaped upper surface 5 of the frame construction block 5
In a, a positioning concave portion 5b is formed slightly inside from the center over the entire circumference of the upper surface 5a, and a positioning convex portion 5d is formed on the lower surface 5c so as to correspond to the positioning concave portion 5b. .

Further, a large number of holes 5h penetrating from the upper surface 5a to the lower surface 5c are formed outside the concave portion 5b and the convex portion 5d, and the positions thereof are oriented at 90 ° as shown in the drawing. When they are stacked upside down while changing the, they communicate.

A connecting recess 5e corresponding to the plate 6 is formed at both ends of the U-shape of the upper surface 5a, and a female female screw 5f for attaching a bolt 7 is provided on the bottom of the connecting recess 5e. Is embedded.

When the pillars are formed by the frame building blocks 5, the frame building blocks 5 prepared in advance at the factory are carried into the construction site, and the frame building blocks 5 face each other on the foundation. And the concrete frame building blocks 5 are connected to each other by plates 6 and bolts 7. At this time, if a tapping screw is used instead of the bolt 7, it is not necessary to embed the female screw 5f at the time of forming the frame building block 5. If a U-shaped scissor is used instead of the plate 6 and the bolt 7, and the scissors are inserted into the holes formed at the positions of the female screws 5f, the working time can be further reduced.

When the second-stage frame building block 5 is combined, the second-stage frame building block 5 is turned 90 ° on the first-stage frame building block 1. And the second stage frame building block 5 as in the first stage.
They are connected to each other using a plate 6 and bolts 7. The positions of the upper and lower frame building blocks 5 are specified by the combination of the positioning recesses 5b provided on the upper surface 5a of the first stage and the positioning protrusions 5d provided on the lower surface 5c of the second stage, and the horizontal direction is obtained. There is no shift. At this time, the plate 6 and the bolt 7 used to connect the frame building block 5 sink into the connecting recess 5e, and the plate 6 and the bolt 7
Is not exposed from the upper surface 5a, so that it does not become a hindrance when stacking the frame building blocks 5 on the upper stage.

In this way, the concrete frame 8 is assembled by assembling the frame building block 5 to the required height of the pillar.
Is formed, and concrete is poured into the space 9 therein, whereby concrete columns can be formed without using a formwork.

Hole 5h formed in frame building block 5
Communicates from the uppermost part to the lowermost part of the frame body 8 when assembled as the frame body 8, by inserting a reinforcing bar or a piano wire into the hole 5 h or by injecting a rubbery bond or the like. The degree of connection between the body building blocks 7 is increased, and the strength and seismic isolation of the columns can be improved. In addition, the diameter of the hole 5h depends on the diameter of the inserted reinforcing bar, the viscosity of the injected bond,
It is arbitrarily determined according to the amount and the like. The formation of this hole is optional.

Further, when a high-strength column is to be prepared, it is only necessary to arrange the internal reinforcement with a reinforcing steel bar, surround the periphery of the column with a frame construction block 5, and then pour the concrete and harden it. .

As described above, the frame itself is formed by the frame building block 5 made of, for example, concrete, and is used as the outer surface of the concrete structure after construction. Concrete columns can be constructed in a short time without the need for dismantling work.

If the frame building block 5 is made to have a volume and weight that can be carried by hand, it can be easily connected to each other so that it can be transported to a construction site or constructed. Work can be performed in a short time without using special equipment and tools.

When a circular column is constructed, as shown in FIG. 3, the frame can be constructed in the same manner as in FIG. 1 by using a frame-building block 12 in which the circumference corresponding to the outer surface of the column is divided. . In addition, the construction method is the same as that of FIG. 1 also in the case of FIG. 2 and FIG.

In this case, the positioning recess 12 is used.
b. If the shape of the positioning projection 12d is not a continuous concave or convex shape but a combination of cylinders and prisms (not shown), the horizontal position and angle can be easily specified.

Also, when pillars on which various stone plates are pasted or painted are required on the outer surface, a 5 g outer surface is required at the factory.
If a frame building block 7 in which various stone plates are pasted on 10g and 12g and a picture is processed is created at a factory, the outer surfaces 5g, 10g and 12g become the outer surfaces of the pillars as they are. Finishing work on the outer surface of the pillar at the construction site becomes unnecessary.

Next, the construction of the retaining wall by the frame building block will be described with reference to FIG. In FIG. 4, 13
Is a frame building block, and 13a is a frame building block 1.
3, 13 b is a positioning concave portion, 13 c is a lower surface of the frame building block 13, 13 d is a positioning convex portion, 13 d.
e is a convex for positioning, 13f is a concave for positioning, 13g
Is a female screw embedded in the frame construction block 13;
h denotes the outer surface of the frame building block 13, 14 denotes a reinforcing bar, 15 denotes a metal fitting, and 16 denotes an angle.

The frame building block 13 is formed to have a slightly larger volume and weight (for example, 800 mm in length, 400 mm in height, 150 mm in thickness, and 30 kg in weight) than columns. . However, when a lifting machine (such as a wrecker) can be used, the size, weight, and shape of each frame building block 13 can be arbitrarily determined.

On the upper surface 13a of the frame building block 13, a positioning recess 13b is formed in a continuous form, and on the lower surface 13c, a positioning projection having a shape corresponding to the positioning recess 13b on the upper surface. 13d is formed. In the figure, the positioning concave portion 13b and the positioning convex portion 13 are shown.
Although d has a continuous shape, it may be a combination of a plurality of cylindrical, triangular, or quadrangular prism-shaped projections and depressions. Also,
Irregularities for positioning may be provided on the upper surface and the lower surface of the frame construction block in a discrete manner.

When the retaining wall is constructed by the frame construction block 13 of the present invention, the first frame construction block 13 is fixed to the foundation, and the front side (front side of the drawing) and the back side (drawing side) are placed thereon. The frame building block 13 of the second stage (in the back side) is arranged in the longitudinal direction. At this time, the second-stage frame building block 13 is superimposed on a position shifted from the first-stage frame by a half of its own length.

Then, the reinforcing bar 14 and the angle 16 are fixed to the female screw 13g from the inside of the frame construction block 13 on the back side (the back side in the drawing). Is screwed. The other end of the tension fitting 15 is connected to an angle 16 fixed inside a frame construction block 13 installed on the front side (front side in the drawing). Further, the reinforcing bar 14 may be used not only vertically but also horizontally as shown in the figure.

The vertically adjacent frame building blocks 13 are fixed to each other by using reinforcing bars 14 and bolts. However, if a higher degree of connection is desired, the upper and lower frame building blocks 13 are bonded together. What is necessary is just to apply mortar containing agents.

The combination of the frame building blocks 13 is composed of upper and lower positioning recesses 13b and positioning projections 13b.
d, and the left and right positioning protrusions 13e and positioning recesses 13f facilitate positioning, assembling a frame from a conventional mold and placing concrete in the frame. Can be constructed in a shorter time than the work of injecting steel and constructing a retaining wall.

As described above, by combining the frame building blocks 13, it is possible to construct various retaining walls having various construction distances and construction heights.

When a high retaining wall is constructed using a formwork, concrete is divided into several steps to prevent the formwork from being cracked by the weight of the concrete to be cast. In such a case, the frame building block 1 of the present invention is adjusted to a height corresponding to each next stage.
3 and after concrete is cast, the work of combining the frame building blocks 13 to the next level and casting concrete may be repeated to the required height of the retaining wall. By doing so, the frame building block 13 and the concrete constructed in the previous stage can serve as a scaffold when constructing the frame constructing block 13 in the next stage, so that it is necessary to form the scaffold from outside the retaining wall. It can be easily installed in narrow places.

In the present invention, the female screw 13g is provided only on one side of the frame construction block 13. However, if it is provided on both sides, the construction can be performed without worrying about the front and back of the frame construction block 13. . The shape of the frame building block 13 is not limited to a rectangle, but may be a triangle, a hexagon, or a circle (and a gap filling shape).

Further, various kinds of stone plates are stuck on the outer surface,
When constructing a retaining wall with a picture, as in the case of pillars, if a variety of stone plates are pasted on the outer surface 13h at the factory or a frame building block 13 that has been processed such as drawing is used. Since the outer surface 13h becomes the outer surface of the retaining wall as it is, the mold is finished finely.

Next, with reference to FIGS. 5 and 6, a case will be described in which a concrete for reinforcement is constructed around a sub pipe of a manhole using a frame building block. FIG. 5 is an explanatory diagram showing an overall outline of a reinforcing concrete frame, and FIG. 6 is an explanatory diagram showing details of a reinforcing concrete frame.

When constructing the reinforcing concrete 4 shown in FIG. 7 using the frame building block of the present invention, the outer peripheral portion of the reinforcing concrete 4 to be formed around the sub pipe 3 The sub-tube 3 is divided in the vertical direction, the lower part 17 is located below the center of the horizontal part 3b of the sub pipe 3, the part covering the upper part from the center of the horizontal part 3b is the middle part 18, the part corresponding to the vertical part 3d is the upper part 19, 17 is divided into two frame building blocks 20, the middle 18 is also divided into two frame building blocks 21, and the upper 19 is similarly divided into two.
It is divided into two frame building blocks 22. These frame building blocks 20 to 22 are used for reinforcing concrete 4.
The construction frame 23 is configured. (See Fig. 5)

Next, the manner in which the concrete 4 for reinforcement is constructed by using the frames 20 to 22 for constructing the frame will be described with reference to FIGS. As in the case of FIG. 7, the frame building block 20 constituting the lower stage 17 together with the manhole 2 is set in the hole dug down, the plate 25 is inserted into the connecting recess 20d, and the bolt 26 is screwed into the female screw 20d. It is combined to form one plate-shaped lower stage 17.

An adjunct 3 made by combining the horizontal part 3b, the elbow 3c, and the vertical part 3d in advance on the ground is placed on the platform 20f of the lower stage 17, and the opening 3a of the horizontal part 3b is opened at the lower side of the manhole 2. Adhere to the part 2c.

Next, the middle stage 18 is constructed by placing the frame building block 21 on the frame building block 20. At this time, positioning recesses 20 are provided in lower stage 17 and middle stage 18.
b, since a plurality of positioning projections 21d are formed, not only the horizontal position but also the horizontal angle can be easily specified only by the combination of the positioning concave portion 20b and the positioning projection 21d, The position of the middle stage 18 is accurately specified on the lower stage 17.

Similarly, the frame building blocks 22 constituting the upper stage 19 may be stacked up to the height of the vertical portion 3d.

Each side of the frame 23 is adapted to be compatible with either a round manhole or a square manhole, and the outer shapes of the frame building blocks 20 to 22 constituting the frame 23 are concave and convex. It consists of a combination with a straight part. Further, the upper stage 19 formed by the combination of the frame building blocks 22 can be superposed even in a state where the orientation is changed by 90 °, so that the construction can be performed without concern for the orientation.

In this way, concrete is poured into the space 24 between the frame 23 and the sub pipe 3 and is hardened, so that a frame can be formed with a form in a narrow place in a hole or dismantled. The reinforcing concrete 4 can be constructed without doing it.

It is needless to say that a hole (see FIGS. 1 to 3) for passing a reinforcing bar or the like may be formed in the frame building block shown in FIGS. 4 to 6.
