Description

[Detailed explanation of the idea] The present invention relates to improvements in reinforcing materials for block walls.

Fences are often built to enclose the boundaries of houses and sites, and in recent years, block walls have become more common as blocks have become popular.

In order to prevent the block wall from collapsing due to earthquakes, etc., reinforcing steel bars are arranged vertically and horizontally inside the block for reinforcement, and a retaining wall is required on the outside.

However, arranging these reinforcing bars vertically and horizontally is time-consuming and is sometimes omitted during the construction stage.

There are also many examples of using large blocks that look like natural stone instead of traditional blocks.

This large block, which has the personality of a natural stone, measures 900 mm in length, 300 mm in height, and 1 mm in width.
It has a length of 50 mm and a weight of about 9 in 40, and requires further reinforcement when used for a fence.

The conventional fence using large blocks is the first.
The structure is constructed as shown in Figure a, and reinforcement in this case is achieved by planting vertical reinforcements 02 on the foundation 01 buried in the ground, as shown in Figure 1 and C, which is an enlarged view of part 0. Build a block wall by stacking large blocks 03 through the reinforcements 02 and arranging horizontal reinforcements 04 at necessary locations.Furthermore, the reinforcing members 06 of the retaining walls 05 are buried deep in the ground, and the retaining walls are constructed at the same time as the fence. A method has been used in which the side vertical reinforcements 02 and the reinforcing member 06 of the retaining wall are connected by a secondary retaining reinforcement 07 and fixed inside the retaining wall 05.

The members used for such conventional reinforcement, such as vertical and horizontal reinforcements, especially the secondary reinforcements, are difficult to install because they are fixed inside the joints of the blocks or inside the through holes provided in the blocks, and it is difficult to install them after completion. The construction work itself was very time-consuming as no one could find the construction work.

The purpose of the present invention is to eliminate such conventional drawbacks, provide an iron column unit for reinforcing block walls that is easy to perform reinforcement work, and can be reinforced reliably. The block wall is constructed by reinforcing vertical reinforcement with one end buried in the foundation and the other end extending upward, and horizontal reinforcement placed perpendicular to the vertical reinforcement, with the lower end buried underground. An iron column having a buried foundation to be buried, and having through holes formed in the front and back of the block wall, and erected in contact with the rear surface of the block wall or the rear end surface of the retaining wall, and one end of the iron column in the through hole. a fixing part through which the thread is passed and fixed, and the other end has an arc shape corresponding to the outer diameter of the longitudinal bar in a plane perpendicular to the axis of the longitudinal bar, and the longitudinal bar is engaged at the center of the arc. a vertical reinforcement connecting portion for positioning, and a vertical reinforcement connecting portion provided adjacent to the vertical reinforcement connecting portion, which has an arc shape corresponding to the outer diameter of the horizontal reinforcement in a plane perpendicular to the axis of the horizontal reinforcement, and the horizontal reinforcement is engaged with the center of the arc. It is characterized by comprising an auxiliary stop bar having a transverse bar connection part for positioning.

Hereinafter, the iron column unit for reinforcing a block wall according to the present invention will be explained in detail based on the drawings.

As shown in Figures 2a-c, the reinforcing steel column unit of the present invention can be installed either in contact with the back of a wall (position A in the figure) or in contact with the rear end of a retaining wall. Steel column 1 when installed (position B in the figure) and vertical reinforcement 2 placed inside the wall
It is composed of a horizontal reinforcement 3 and an auxiliary stop reinforcement 4 that connects the steel column 1.

First, these constituent members will be explained.

As shown in Fig. 3, the steel column 1 is made of miso-shaped steel with the opening facing toward the block, and has a long hole on the back that passes through the front and back for fixing with a nut through the sub-retaining bar described later. 1a is provided.

This elongated hole 1a is long in the vertical direction, and there is no problem even if it is an elongated hole in terms of reinforcement strength.

Further, at the lower end of the steel column 1, an integral structure is formed by cutting each corner portion of the lower end of the steel column 1 and bending the cut portion outward as a buried foundation 1b.

In addition, instead of a monolithic structure, various shapes (commercially available shaped steel) as shown in Figure 4 a to h may be fixed by welding, etc. For example, in a, the opening part of the miso shaped steel is fixed upward. For this purpose, there are those that allow soil etc. to be put inside this miso shaped steel,
It is conceivable to use various types of shaped steel, such as angle shaped steel with the opening facing upward in the same way as shown in b.

The secondary reinforcement bars 4 are used to simultaneously fix the vertical reinforcements 2 and horizontal reinforcements 3 arranged inside the wall near their intersections and connect them to the steel column 1. As shown in Fig. 5a, one end of the round bar 4a A male screw 4 as a fixing part is inserted into the steel column 1 to fix it.
d is formed, while at the other end there is a transverse bar connecting part 4 bent into an arc shape corresponding to the outer diameter of the transverse bar 3 within a plane perpendicular to the axis of the transverse bar 3.
b is formed, and furthermore, a vertical reinforcement connection part 4C is formed continuously at the tip of this horizontal reinforcement connection part 4b and bent into an arc shape corresponding to the outer diameter of the vertical reinforcement 2 in a plane perpendicular to the axis of the vertical reinforcement 2. .

Therefore, the horizontal reinforcement 3 can be positioned in an engaged state at the arc-shaped center of the horizontal reinforcement connection part 4b with this secondary stop bar 4, and the vertical reinforcement 2 can also be engaged with the arc-shaped center of the vertical reinforcement connection part 4C. It can be positioned in the correct state and fixed securely.

In addition, other shapes of the secondary retaining bars are shown in Fig. 5, for example.
The one shown in c is possible.

That is, the auxiliary stop bar 5 shown in FIG. 5 has a male thread 5d as a fixing part formed at one end of the round bar 5a in order to be inserted into and fixed to the steel column 1, while the other end is bent at a right angle. A cutout is made by fixing the plate materials by welding or the like, and the plate material is parallel to the plane perpendicular to the axis of the horizontal reinforcement 3, and has an arc shape corresponding to the outer diameter of the horizontal reinforcement 3, and a cutout at the diagonal lower part so as not to impede strength. 5e is formed to form a horizontal reinforcement connecting portion 5b, and an arc-shaped hole corresponding to the outer diameter of the vertical reinforcement 2 is formed in a plate shape that is perpendicular to the horizontal reinforcement connecting portion 5b and parallel to a plane perpendicular to the axis of the vertical reinforcement 2. This forms a vertical reinforcement connecting portion 5c.

That is, if the arcuate shape formed in the horizontal stripe connecting portion 5b and the vertical stripe connecting portion 5C is formed on the inside of a concave shape corresponding to the outer diameter of the horizontal stripe 3 or the vertical stripe 2, then the outer side of the arc shape will be It may have any shape.

Therefore, by passing the vertical reinforcement 2 through the hole of the vertical reinforcement connection part 5C, the vertical reinforcement 2 is positioned in an engaged state at the center of the hole, and then the horizontal reinforcement 3 is inserted using the notch 5e of the horizontal reinforcement connection part 5b. If it is located at the center of the circular arc, it can be positioned in an engaged state and securely fixed.

Note that the notch 5e may not be formed in the horizontal reinforcement connection portion 5b, but may be formed in connection with the hole of the vertical reinforcement connection portion 5c, or may be provided in both.

Further, the secondary stop bar 6 shown in FIG. 5C differs only in the width stop bar 5 and the transverse bar connecting portion 6b.

A male screw 6d as a fixing part is formed at one end of the round bar 6a for inserting and fixing it into the steel column 1, and at the other end, a plate bent at right angles is fixed by welding or the like, and the transverse reinforcement 3 of the plate is fixed.
A plate parallel to the plane perpendicular to the axis of the horizontal bar is arranged so as to protrude upward, and an arc-shaped projection corresponding to the outer diameter of the transverse bar 3 is formed in this part to form a transverse bar connecting part 6b. A vertical reinforcement connecting portion 6c is formed at right angles to the vertical reinforcement connecting portion 6c.

Therefore, the vertical reinforcement 2 is positioned in an engaged state at the center of the hole of the vertical reinforcement connection part 6c, and the horizontal reinforcement 3 is positioned in an engaged state in the center of the arc of the protrusion while being placed on the plate material of the vertical reinforcement connection part 6c. and can be securely fixed.

In addition, the large block 8 used has a length of 900 mm, a height of 300 mm, and a width of 1501 r as shown in Fig. 6 a and b.
It weighs approximately 40 kg, and the upper front edge 8a of the front side is rounded, and the lower front edge 8b is slightly shaved off, so that when stacked, grooves run horizontally, giving it the appearance of natural stone. have

Vertical grooves 8c are provided at both ends of this block, a through hole 8d is provided in the center, and four holes 8e whose upper ends are closed in order to reduce the weight in the vertical direction are provided in the figure.

Further, the horizontal reinforcement block used for arranging the horizontal reinforcement has a U-shaped groove 8f on its upper end surface.

Steel column 1 and sub-stop bar 4 (with such buried foundation 1b)
5, 6) and the construction of a block wall using the large block 8 is carried out as follows.

As shown in Figure 2 a+b+c, the foundation 9 is constructed by arranging vertical reinforcements 2 in the foundation 9, which is half buried in the ground, and solidifying it with concrete.

The vertical bars 2 used in this case may be of the split type already proposed in Utility Application No. 54-46911, or of the conventional integrated type, but from the viewpoint of implementation, it is better to use the split type. desirable.

In addition, in parallel with this foundation 9, bury the buried foundation 1b by about 600 mm at position A where the steel column 1 contacts the rear face of the wall, or at position B where it contacts the rear end face of the retaining wall if a retaining wall is provided. Make yourself independent.

Then, the large blocks 8 are stacked on the foundation 9, and the horizontal reinforcements 3 are arranged where necessary, and the vertical reinforcements 2 and the horizontal reinforcements 3 are connected at the same time with the secondary reinforcements 4 (or 5, 6), and the secondary reinforcements are Pass the male threaded side through the long hole 1a of the steel column 1 and tighten with a nut.

Figure 7 a+b shows the connection state when using this sub-retaining bar 4.
It is shown enlarged.

Then, the vertical stripes, the transverse strips, the grooves 8c between the sub-stop bars 4 (or 5.6) and the flocks 8, etc. are filled with mortar, and the flocks are also connected with mortar.

Furthermore, the space between the iron pillar 1 and the fence is also filled with mortar.

In this way, the blocks are stacked one after another to achieve the required height, and the fence cap 10 is placed on the top of the fence to complete the construction.

As explained above in detail along with the examples, according to the present invention, reinforcing with reinforcing bars, which conventionally required time and effort to reinforce block walls and was sometimes omitted at the construction stage, is replaced by sub-reinforcing bars and buried foundations. By using a reinforcing steel column unit that consists of a steel column with a steel column, reinforcement work can be carried out easily and reliably, and since one end of the secondary bar is fixed with a nut on the outside of the steel column, the state of reinforcement can be visually checked, making it possible to perform manual work. There is no such thing as

In addition, the secondary bar is equipped with a vertical bar connection part and a horizontal bar connection part that position the vertical bar in an engaged state at the center of the arc, and position the horizontal bar in an engaged state at the center of the arc, which saves work. With this technology, stronger reinforcement can be achieved than in the past, where only either the vertical or horizontal reinforcement could be connected.
