Description

[Detailed Description of the Invention] 3. Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a concrete block for constructing walls and the like, and a method of constructing the concrete block.

<Prior Art> Conventional concrete blocks are rectangular with hollow ribs, and each time the blocks are piled up, mortar is applied to the top and side surfaces of the blocks using a triangular trowel.

In addition, the horizontal reinforcing bars are installed in advance, and the reinforcing bars are arranged by inserting horizontal reinforcing bars every few stages and tying them with wire at the points of intersection with the horizontal reinforcing bars.

<Problems to be Solved by the Invention> The role of the joint mortar is to maintain the joint strength between the blocks and to provide a beautiful design with a constant joint width of, for example, about 10m/m.

However, in the above-mentioned conventional construction method, the quality of the joint mortar varies, which impairs the aesthetic appearance, joint strength, and durability.7, Mortar is used each time a block is laid, so the work has to be carried out in the middle of the process in case of rain. As a result, the composition of the joint mortar changes due to rain, and the resulting color changes have a major impact on the aesthetics, strength, and durability of the joints.

In addition, arranging vertical and horizontal reinforcing bars to be inserted into blocks requires a complicated process, which affects work efficiency.

Means for Solving the Problems> The present invention provides a concrete block and a method for constructing the same, which are provided in order to solve the above-mentioned conventional problems. A joint mortar filling port 741 having a predetermined joint width is formed on one side. In addition, vertical and horizontal reinforcing bars are set up in advance in a lattice pattern, concrete blocks are inserted through the lattice holes in the rectangular spaces, and the masonry is assembled, followed by filling the joint mortar and concrete block cavities with concrete.

Effects> The present invention has the effect of increasing the aesthetic appearance and joint strength by always keeping the joint width constant, and also has the effect of improving the efficiency of reinforcement, masonry accuracy, and masonry efficiency.

Embodiments Hereinafter, embodiments of the present invention will be described based on the drawings. 1 to 4 show concrete blocks of the present invention. 1
is the block body, which is rectangular in shape with an internal cavity having ribs 2, and is similar to a conventional concrete block. The present invention provides protrusions 3 and 4 on both sides of the block body 1 as well as on either the top or bottom (ground side in the example of the figure), and the protrusions 3 and 4 allow masonry to be stacked to form a joint width equivalent to the width of the joint between adjacent blocks. It is characterized by a structure in which a groove for filling joint mortar is formed at 5°6.7°.

Generally, the joint width on the surface side is about 10i+/m. Therefore, the height Ll of the protrusion 6 forming the joint mortar filling groove 6 on the ground side is 10 m/m, and the height L2 of the protrusion 3 forming the joint mortar filling groove 5 on both sides is ml.
/2. That is, the height of the protrusion 6 is 5 m/m. Reference numeral 8 denotes a recessed part provided on the ground side of the rib 2, which, together with the joint mortar filling groove 5.6.7, is involved in the concrete block construction method of the present invention, which will be described later.

The concrete block of the present invention having the above structure has a fourth
As shown in the figure, horizontal joint mortar filling grooves 6 corresponding to the joint width are formed by protrusions 6 between adjacent block bodies 1 in the vertical direction, and between adjacent blocks in the left and right direction, mutual contact between the left and right block bodies 1 is formed. The joint mortar filling grooves 5 formed by the projections 3 form vertical joint mortar filling grooves corresponding to the width of the joint. Furthermore, joint mortar filling grooves 7 in the vertical and W directions are also formed in the cavity inside the block body 1.

Therefore, after the block main body 1 is assembled, by filling the joint mortar filling grooves 5 and 6 with special mortar on the surface side, it is possible to construct joints with a constant width at all times. In addition, by the usual method of pouring concrete into the cavity of the block body 1, the concrete poured into the cavity is automatically filled into the inner joint mortar filling groove 7, and the joint mortar is filled from both the inside and outside. The filling form is as follows. Therefore, the aesthetic appearance of the surface side is improved by the constant joint width, and the strength of the joint is increased by filling the joints with mortar on both the inner and outer sides.

Next, a method for constructing a concrete block according to the present invention will be explained with reference to FIGS. 5 to 7. As shown in FIG. 5, a lattice-like reinforcing bar is established in advance at a location lO where a concrete block is to be constructed, in which longitudinal reinforcing bars 11 and lateral reinforcing bars 12 intersect and the intersection points are joined by welding or the like. Here, the grid-like rectangular space 13 has approximately the same size as the rectangular size of the concrete block used for construction.

Moreover, the concrete block used for construction is the concrete block having the structure according to the present invention described above.

The block body 1 is inserted into the pre-established lattice reinforcing bars from the rectangular space 13 and assembled. This insertion of the block body 1 is done by tilting the block body 1 in two directions, with the side of the recessed part 8 of the rib 2 facing the horizontal reinforcing bar 12, and the side face of the block body 1 facing the vertical reinforcing bar 11. As shown in FIG. 6, the reinforcing bars 11 and 12 are inserted from the space 13 and stacked one after another so that the vertical and horizontal reinforcing bars 11 and 12 penetrate into the cavity of one block body 1. By assembling this block body 1, it can be vertically moved as described above.

Horizontal joint mortar filled grooves on the left and right 6. Vertical joint mortar filling grooves 5 and inner joint mortar filling grooves 7 are formed, and as shown in FIG. to construct the block body. -<Effects of the Invention> As described above, according to the present invention, the joint mortar filling grooves of a predetermined width formed in the block body are filled with special mortar and filling concrete after block masonry. Since the width is constant, the aesthetic appearance is improved regardless of skill, and since there is no variation, the strength of the joint is significantly improved. In addition, for the vertical and horizontal reinforcing bars arranged inside the block body, reinforcing bars are set up in a lattice shape in advance at the block construction part, and the block body is assembled by inserting into the lattice reinforcing bars. Filling joints with mortar Since the joints are placed in the grooves and the concrete is filled into the cavity of the block body, construction efficiency and precision are improved, and even in rainy weather, it is possible to assemble the block body. This work can be completed, and has advantageous effects in terms of construction period and economy.
