Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a block masonry structure constructed by laying bricks and concrete blocks, which are particularly excellent in earthquake resistance.

[0002]

2. Description of the Related Art Brick and concrete blocks have been widely used as building materials and landscaping materials since they have good handling performance as a single body and can be combined into various structures.

In particular, bricks formed by baking clay have a good color tone and excellent weather resistance, and have been popular in many countries around the world for a long time and are also used as wall materials for buildings. When used as a wall material in this way, conventionally, a masonry structure is formed by bonding the bricks with mortar.

[0004]

However, in the conventional masonry structure, since the bricks are integrated by the adhesive force of the mortar, the strength of the structure is not sufficient, and especially in the horizontal load. I can hardly resist it. For this reason, in Japan where there are many earthquakes, it is the current situation that it has not been sufficiently spread as a wall material for buildings.

Further, since such mortar construction requires a high level of technology such as the thickness of the mortar and the brick passage, it is performed by a plasterer as a professional.
Due to the recent shortage of manpower, it is becoming difficult to secure professionals.

[0006] Such a problem applies not only to bricks made by firing clay but also to concrete blocks having the same shape.

[0007] Therefore, the problem to be solved by the present invention is to obtain a block masonry structure which can be easily constructed without requiring any special technician and is excellent in earthquake resistance.

[0008]

In order to solve the above-mentioned problems, the block masonry structure of the present invention is provided with a vertical through hole in the central portion and vertical semicircular grooves on both sides. A plurality of block bodies are arranged in the vertical and horizontal directions so that the through holes and the semicircular grooves are alternately continuous, and the through holes and the adjacent blocks are provided on the joint surfaces of the vertically adjacent block bodies. A plate-like horizontal reinforcing member having mounting holes at positions corresponding to the holes formed by the semi-circular grooves of the main body, and straddling at least the left and right adjacent block main bodies is arranged, and the through hole is further provided. It is characterized in that the block main bodies are tightened and integrated by a tightening tool arranged inside.

It is also possible to interpose a washer for transmitting the prestress of the tightening tool to the block main body on the horizontal reinforcing member, and further to inject joint mortar into the horizontal joint after tightening.

Here, as the block, a brick or concrete block made of clay by burning clay can be used.

As the horizontal reinforcing member, a plastic sheet or a thin steel plate reinforced by a wire mesh is used, and together with the injection mortar to be used later, the block bodies are connected in the horizontal direction, and the load is applied to the entire block masonry. Can be dispersed in.

Further, as the tightening tool, there is constructed a tightening tool body having a length capable of tightening one or a plurality of block main bodies by one group, and forming a male screw part at a lower end and a female screw part at an upper end. A plurality of blocks can be used depending on the height of the block masonry.

By thus forming the tightening tool composed of a plurality of tightening tool bodies, it becomes possible to freely tighten the block main body of each layer, and it corresponds to the stress distribution of the member obtained by the structural design or the stress analysis. Can be a prestressed distribution. For this reason, it is desirable to use a torque wrench with a torque meter to tighten the tightening tool.

Further, when the prestress is sequentially introduced from the lower stage, the tightening force of the upper layer extends to the lower layer, and according to the experiment of the present inventor, when the tightening force of each layer is constant, the tightening force of the sixth layer is 1 About three times as much prestress will be introduced into the block body of the layer. That is, a large prestress can be obtained with a small tightening force.

In the block masonry structure of the present invention, the block main bodies that are superposed are integrated with each other by the connector and the plate-like horizontal reinforcing member. For this reason, the block main bodies are excellent in joining force, and the entire block wall can resist the load. Furthermore, since the block wall can be constructed only by connecting the preformed through holes continuously and mechanically connecting them, the movement of the block body can be adjusted by loosening the tightening tool even after the construction.

As shown in FIG. 1, the block main body 1 made of brick has a rectangular parallelepiped shape, and a through hole 1a is provided in the longitudinal direction in the central portion for inserting and placing a tightening tool 2 which will be described later.
Semicircular grooves 1b are provided on both sides. In the case of the embodiment shown in FIG. 2, the corners on both upper sides in the width direction of the block body 1 are L-shaped.
The character-shaped cut portion 1c is formed so that the joint portion can be easily treated. In addition, as shown in FIG. 3, when the hanging parts are formed on both lower sides in the width direction of the block body 1, the horizontal reinforcing members when stacked vertically are not directly visible from the outside,
It can also be used to improve the accuracy of stacking. Although not shown, the cut portion 1c is only on the front side of the structure.
It is also possible to provide a joint on the back side which is invisible to the eye as in the basic shape of FIG.

As shown in FIGS. 4 and 5, the block bodies 1 having the above-described structure are arranged in a zigzag pattern.

The tightening tool is inserted through the through hole 1a and the hole formed by the semicircular groove 1b of the adjacent block body 1, and the block bodies 1 superposed and arranged are connected and integrated to each other. It is composed of an anchor bolt 2 and a nut 3.

A horizontal reinforcing member 5 made of a plastic sheet or a thin steel plate for wire mesh reinforcement and a washer 4 arranged on the upper surface of the horizontal reinforcing member 5 are sandwiched between the laminated block main bodies 1. There is.

Next, the procedure for constructing the block masonry of this embodiment will be described with reference to FIGS.

When placing the concrete foundation 10, an anchor bolt 11 having a nut is arranged, whereby
The anchor bolt 11 is fixed to the concrete foundation 10.

Further, a hard sponge 12 which absorbs dimensional errors of the block body 1 and secures a horizontal passage is inserted between the block 1 of the first stage and the front surface of the block body 1 is aligned. Moreover, the through holes 1a or the grooves 1b are arranged so that the centers thereof are aligned.

Next, the groove 1b of the block body 1 of the first stage
Insert the lowest nut 3 into the hole formed by
It is screwed onto the upper end of the anchor bolt 11. As a result, prestress is introduced into the block body 1 of the first stage and the block body 1 is integrated with the concrete foundation 10.

Further, the reinforcing mortar sheet 5 is inserted on the upper surface of the block body 1 of the first stage, the block bodies 1 of the second and third stages are integrated by the same procedure, and finally, the nut 3 of the uppermost stage. A fixing tool (not shown) is screwed onto the. Mortar is injected into the vertical joints between the blocks by an injector. This injection mortar has a function as a joint material,
The rust preventive effect of the washer 4 can be achieved.

As described above, the block main bodies 1 are integrated in the horizontal and vertical directions, and a block masonry structure excellent in earthquake resistance is completed.

As described above, the block masonry structure of this embodiment is not only vertically connected by prestressing by the nut 3, but also horizontally connected by the plate-shaped horizontal reinforcing member 5, so that the conventional structure is realized. Compared to the one, the whole block masonry wall can resist the load and the earthquake resistance is dramatically improved.

Further, since the prestress is introduced into the block body 1 of each layer by the plurality of tightening tools 2 and 3, a large prestress can be obtained with a small tightening force. In particular, by sequentially tightening from the lower layer, the tightening force of the upper layer is accumulated as a prestress to the lower layer, so that a large pre-stress can be introduced to the lower layer where stress is particularly concentrated during an earthquake or the like.
