Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a joint width adjusting tool which allows even an amateur to easily and quickly finish the joint thickness to a constant value when stacking bricks and blocks.

[0002]

2. Description of the Related Art Generally, it is said that it requires skill to finish a joint width constant when stacking bricks and blocks, but in the recent construction industry, the number of skilled workers is decreasing and the number of temporary craftsmen is increasing. On the other hand, the number of do-it-yourselfers is increasing, and bricks and concrete blocks are piled up at home to build fences and gardens. Under such circumstances, an auxiliary tool for stacking concrete blocks has been developed as disclosed in Japanese Patent Laid-Open No. 10-184024 for the purpose of keeping the joint width constant and facilitating the work and at the same time making the joint strong. There is. However, since this tool has a complicated structure and is expensive, when a large number of blocks are stacked, a large amount of this auxiliary tool must be used in proportion to the amount of the blocks, which increases the construction cost. There is a drawback that it is avoided from use due to a balance with labor-saving effect, and there is room for improvement.

[0003]

DISCLOSURE OF THE INVENTION The present invention provides a joint width adjusting tool, which can be finished by a temporary worker or an amateur, very easily, quickly and with a uniform joint width at a very low cost. It was developed for that purpose.

[0004]

In order to achieve the above object, the joint width adjusting tool of the present invention uses a thin iron plate (or a plate material of a similar material, hereinafter the same) in an I-shape having the same dimension width as the joint width. A joint width adjusting tool A is formed by cutting into a mold and forming bending grooves at predetermined positions from both ends thereof. Similarly, the upper and lower ends of a thin iron plate formed in a substantially E shape with the same size as the joint width. The joint width adjusting tool B is provided with a bending groove at a predetermined position from the above, and is provided in advance by bending at each bending groove at a right angle, or provided in a flat plate shape, and bent at the work site. It is designed so that it can be used.

Since the joint width adjusting device of the present invention has an extremely simple structure, it can be used very easily by not only professional craftsmen but also temporary workers and do-it-yourselfers. For example, in the case of brick stacking, when stacking the first brick (first brick) on the end edge of the smoothed foundation, the joint width adjusting tool A is 10 to 15 mm from the edge of the foundation.
Place in a state of lying inward, and press the joint width adjuster B downward from above with the joint width adjuster B applied to the inner edge of the brick to fix the joint width adjuster A and the joint width adjuster B to the foundation surface. . The next brick has the next joint width adjustment tool B
Apply the other side (outer side) along the rising part of the front joint width adjuster B from above to below.
By repeating this, the stacking of the first stage is completed.
At this time, the edge of the last brick is placed on the mortar with the joint width adjusting tool A at a predetermined distance from the edge like the first brick. The mortar is poured into the space between the bricks, the mortar protruding from the joint is removed, and the first-stage stacking is completed.

By repeating the same operation from the second stage onward, the brick laying work can be easily carried out, and the finished condition can be piled up neatly with the same width by both an expert and an amateur.

As described above, since the joint width adjusting tool of the present invention has a simple structure and can be provided at an extremely low cost, even if it is adopted by a builder, the work efficiency can be improved to the same level as a veteran craftsman or more even in a temporary work. It can contribute to shortening construction period, saving labor cost and increasing credit. When used by amateur do-it-yourself enthusiasts, the effect of being able to fully enjoy the finish of a professional job can be exhibited.

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described in detail below with reference to the drawings.

[0009]

Example 1 A thin iron plate having a wall thickness of about 0.5 mm is cut into an I-shape having the same size as the width of the joint 1, for example, a width of 10 mm and a length of 70 mm, and a position inward from each end by about 15 mm. Joint width adjuster A with a kerf 2 for bending
Similarly, a thin iron plate having a width of 10 mm, which is the same as the joint width, is cut into a substantially E shape composed of an upper side 3, a lower side 4 and a center side 5 of 50 mm, and the center side 5 is cut from both upper and lower edges. A joint width adjusting tool B is provided with a kerf 2 for bending at a position 20 mm inward, and each joint is provided with a kerf for bending at a right angle in advance, or while being bent at a work site. It is intended to be used. Instead of a thin iron plate, a metal other than iron, a synthetic resin, or a cardboard can be used as long as the material can maintain a predetermined shape until the mortar dries and can be assimilated with the mortar.

[00010]

[Example 2] The joint width adjusting tools A and B of the present invention will be described by way of example of brick laying. The mortar 6 is placed on a foundation C whose upper surface is treated horizontally to a thickness of about 13 mm, and When stacking the first brick 7 to be piled up on the edge portion of C, the joint width adjusting tool A bent at a right angle in advance in the bending groove 2 is used from the outer edge 8 to 10-1 of the brick 7.
It is placed in a state lying sideways on a portion corresponding to 5 mm inward, and the edge 8'on the opposite side of the brick 7 is preliminarily bent at a right angle at the bending portion 2 at the center side 5 of the joint width adjusting tool B. One side 10 of the rising part 9 of the brick is applied and the bottom part 1 of the brick 7
The upper and lower sides 3 and 4 of the joint width adjuster B have shoulders 1 on one side.
With 1 applied, the joint width adjusters A and B are pressed downward from above and fixed to the foundation C.

Like the brick 7, the next brick 7'applies the joint width adjusting tool B on one side (inward) and the other side (outward) rises on the central side 5 of the front joint width adjusting tool B. Push down from the top along the opposite side 10 'of the part 9. By repeating this, the stacking of the first stage is completed.

At this time, the joint width adjusting tool A is arranged at the end edge portion of the last brick at a position closer to the inner side by 10 to 15 mm like the brick 7 of the first end edge. Moreover, the mortar 6 is poured into the gap between the bricks, and the mortar 6 that has overflowed is removed before the mortar 6 has dried. When the stacking work of the first stage is completed, mortar 6 is applied on it and the same work as the first stage is performed. Thereafter, by repeating this work, the brick laying work can be easily performed.

[0013]

Since the present invention is constructed as described above, it has the following effects.

All of the joint width adjusting tools of the present invention have a simple structure, but the joint width can be adjusted to a constant width regardless of who works, and it is extremely easy for both temporary workers and amateurs to Since it can be finished quickly and neatly, it is economical not only for saving labor costs but also for the work shop, etc. where a large amount of bricks and concrete blocks must be piled up, because it can respond with a short construction period and temporary work with low wages. The effect is tremendous, and the finish is beautiful, so the technical reliability is improved, and the effect is immeasurable.

Further, the joint width adjusting tool of the present invention includes a thin iron plate formed in an I-shape and a thin iron plate formed in a substantially E-shape, in which bending grooves are provided at predetermined positions from both ends. Since the groove for bending is provided at a predetermined position from both ends, the structure is extremely simple and the manufacturing can be performed at low cost. Also, when it is sold in a state where it is not bent at the kerf, it can be delivered to the end in an extremely compact state, so packaging costs and shipping costs can be extremely saved, and it can be provided at a lower cost. In addition, it has many characteristics such as efficient use of time because a brick-and-mortar construction work, which is suspended in rainy weather, can be used for bending work in a spare time.
