Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention is particularly excellent in earthquake resistance,
The present invention relates to a block masonry structure constructed by laying brick and concrete blocks.

[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 has a plurality of block main bodies having through-holes provided in the longitudinal direction and arranged so that the through-holes are continuous. , A plate-shaped horizontal reinforcing member having a mounting hole at the same position as the through hole at the joint surface of the vertically adjacent block bodies and straddling at least the horizontally adjacent block bodies, and the through hole It is characterized in that the block main bodies are tightened and integrated by a tightening tool arranged inside.

Further, a spring washer is provided on the horizontal reinforcing member to prevent loosening of the tightening tool, a washer for transmitting prestress of the tightening tool to the block body, and a dimensional error of the block body is absorbed to ensure a horizontal passage. It is also possible to interpose a hard sponge which is used, and to further 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.

The horizontal reinforcing member uses a plastic sheet reinforced with a wire mesh and horizontally connects the block bodies together with the injection mortar to be used later so that the load is distributed over the entire block masonry. You can

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 body.

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.

[0015]

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-shaped 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 by simply connecting the preformed through-holes and mechanically coupling them, it is possible to adjust the movement of the block body by loosening the coupling tool even after the construction.

[0016]

FIG. 1 is a front view of a block masonry structure of the present invention,
2 is a side view of the same, and FIG. 3 is a perspective view during construction.

The block main body 1 made of brick has a rectangular parallelepiped shape, and two through holes 2 are provided in the vertical direction for inserting and arranging a tightening tool 3 which will be described later. As shown clearly in FIG. When the block main bodies 1 are stacked, the front surfaces of the block main bodies 1 are aligned and the through holes 2
The block main bodies 1 are arranged in a staggered manner so that the lines are aligned with each other.

The tightening tool 3 is inserted through the through hole 2 and connects and superposes the block main bodies 1 which are overlapped with each other. The anchor bolt 11 and the block main body 1 are internally connected as shown in the perspective view of FIG. An upper end portion 4b formed with a female screw 4a and an insertion portion 4 continuous with the upper end portion 4b and formed with a male screw 4d at the lower end.
and a plurality of tightening tool main bodies 4 including c.

Between the stacked block bodies 1, a horizontal reinforcement member 6 made of a plastic sheet for wire mesh reinforcement and a washer 7 arranged on the upper surface of the horizontal reinforcement member 6 are provided.
a, a spring washer 7b for locking, and a hard sponge 7c that absorbs dimensional errors of the block body 1 and secures a horizontal passage are sandwiched.

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 an upper end portion having the same structure as the upper end portion 4b of the tightening tool body 4 is arranged, and thereby the anchor bolt 11 is fixed to the concrete foundation 10.

Further, a hard sponge 7c 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 2 are arranged so as to be aligned.

Next, the tightening tool main body 4 at the lowermost stage is inserted into the through hole 2 of the block main body 1 at the first stage and screwed with the upper end of the anchor bolt 11. At that time, a state in which a horizontal reinforcing member 6 provided with a mounting hole 6a for the insertion portion 4c of the tightening tool body 4, a washer 7a arranged on the upper surface of the horizontal reinforcing member 6, and a spring washer 7b for preventing loosening are respectively interposed. Screw together. 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, a hard sponge 7c 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 tightening tool body of the uppermost stage. A fixing tool (not shown) is screwed onto the female screw 4 a of No. 4.
The mortar 8 is injected into the horizontal joint between the blocks by an injector. This injection mortar 8 can not only function as a joint material, but also have the rustproof effect of the washer 7a and the spring washer 7b.

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 tightening tool 3, but also horizontally connected and integrated by the plate-shaped horizontal reinforcing member 6. Compared to the conventional one, the entire block masonry wall can resist the load, and the earthquake resistance is dramatically improved.

Since a plurality of tightening tool main bodies 4 introduce prestress to the block main body 1 of each layer, 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.

[0028]

According to the present invention, the following effects can be obtained.

(1) Since the block bodies that are superposed and arranged can be integrated with each other by the tightening tool and the plate-like horizontal reinforcing member, it is possible to resist the load in the horizontal direction on the entire block wall, It has excellent earthquake resistance.

(2) Since a plurality of block bodies can be integrated by tightening the tightening tool, it is possible to loosen the tightening tool and adjust the movement of the block body even after the construction. It will be possible.
