Description

[Detailed Description of the Invention] This invention mainly relates to concrete blocks for use in constructing houses, fences, and other structures.

[Conventional technology]

This type of block, which has been generally provided in the past, has a substantially rectangular parallelepiped body, and has a plurality of approximately elliptical holes extending downward from the upper surface of the main body at the required pitches, and has a plurality of approximately elliptical holes extending downward from the upper surface of the body at both left and right ends of the main body. Toward this end, blocks that are integrally formed with recesses such as semi-elliptical arc shapes are generally provided.

[The problem that the idea aims to solve]

When constructing various structures using blocks configured as described in the conventional technology, the first stage is arranged in multiple rows horizontally, cement mortar is applied to the upper surface of each block body, and the blocks are stacked and arranged in rows on top of this. After all of the block bodies are leveled, the blocks are constructed by filling the through holes with cement mortar.

For this reason, the construction work requires a lot of time and skill, resulting in extremely poor workability.Moreover, since each layer of cement mortar is filled into the perforated hole, a peeling layer is likely to occur, and as a result, the entire structure is damaged. There is a risk that it will not harden uniformly and firmly. For this reason, there are many problems such as being weak against external forces such as earthquakes, wind pressure, and other vibrations.

Therefore, the present invention was devised in view of these problems in the scope of conventional technology, and its purpose is to make stacking and construction work simple, reliable, and quick, and to ensure safe and strong construction. The object of the present invention is to provide a concrete block for construction that can be easily constructed.

[Means to solve the problem]

In order to achieve the above object, the construction concrete block of the present invention has a main frame of approximately rectangular shape, which is installed parallel to the outside, and has a protruding strip extending in a vertical line downward from the required position on the upper surface of the left end. a connecting frame integrally provided with both the left and right ends of the main frame, which is integrally protruded toward the upper surface of the main frame, and which is provided with a cutout groove facing downward from the upper surface of the right end into which the above-mentioned protrusion can be fitted; A reinforcing bar insertion groove with a semicircular arc shape in cross section is formed in the center of the upper surface.The reinforcing bar insertion groove is formed in the center of the upper surface from the inside of the required position on the upper surface of the connecting frame and the main frame. A plurality of locking pin insertion holes are drilled on the joint frame surface at positions where the locking pin is securely engaged at the four corners of the lower inner surface of the locking hole formed in the shape or on the required inner surface, and a locking pin integrally molded with a generally U-shaped concave portion that can be opened outward along the outer surface of the left and right coupling frame, and bored in the upper surface of the coupling frame. All the locking pins fitted into the insertion holes engage with the four corners of the lower inner surfaces of the locking holes of the blocks stacked on top, or with the required inner surfaces of the blocks stacked on top, so that the stacked blocks are integrated. It is a block constructed so that it can be locked and built firmly.

〔Example〕

Below, according to the drawings showing the implementation of the present invention,
The aspect will be specifically explained.

A is a block main body (hereinafter referred to as the main body), and the main body has 3 vertical lines extending from the left end upper surface of the main frame 1 and 2 provided parallel to the outside from the required position to the lower surface. The inner side of the main frame 1 and 2, which has a protruding strip integrally protruding outward, and has a notch groove 4 directed downward from the upper surface of the right end into which the protruded strip 3 can be fitted; A locking hole 10 having an elongated planar rectangular shape, a rectangular shape, or any other suitable shape is formed from the top surface inside the connecting frames 5 and 6 integrally provided at required positions on both the left and right sides and the main frame 1 and 2. On both sides of the joint frame surfaces 5 and 6 of the reinforcing bar insertion grooves 7 and 8, which penetrate toward the lower surface and are formed in the center of the upper surface of the joint frames 5 and 6 and have a substantially semicircular cross section. At the four corners of the lower inner surface of the locking hole 10 or the required inner surface, the outer surface 14 of the locking pin 15 is securely engaged.
A block body A is integrally formed with a plurality of locking pin insertion holes, and concave portions 11 and 12 that are opened outward along the outer surfaces of the left and right coupling frames 5 and 6. All the 15 locking pins fitted into the 9 locking pin insertion holes provided in plurality as described above at the required positions on the upper surface of the main body of A are connected to each other stacked above. This concrete block for construction is characterized in that it can be constructed in one piece by engaging with the four corners of the lower inner surface of the locking hole 10 of the block body A, or with the required inner surface.

It should be noted that the 15 locking pins used in the present invention are not necessarily limited to the form shown in FIG.
As shown in the figure, 19 protrusions are bored in the longitudinal direction of the upper center of the main frame, and 20 grooves into which the protrusions can fit are provided on the lower surface, making stacking work easier. This can be done more reliably, and the 18 filled cement mortar can be prevented from flowing out.

[Effect of idea]

Since the present invention is configured as described above,
The effects described below can be achieved.

Regarding the effect on the arrangement and stacking operations, as shown in FIGS. 3 and 4, the main bodies 1 and 2 of A are placed in the notch grooves in the right end surfaces 4 of the main frames of the main bodies 1 and 2 of other A. , 2 protruding from the left end surface of the main body frame, 3 protrusions are inserted and fitted in a row,
The outer surfaces of all the locking pins 14 are fixed by inserting the insertion shafts of the lower portions 13 of the 15 locking pins into the locking pin insertion holes of 9, respectively, which are drilled on the upper surface of the joint frames of the main bodies 5 and 6 of A. , the lower four corners of the locking hole of the main body 10 of each block A stacked on top, or
It engages with the required inner surface and is securely locked, thereby making it possible to easily arrange and stack each block body A in a simple, reliable, and extremely efficient manner without requiring any skill or effort. effective.

Next, to discuss effects such as strength of the structure, the locking hole 10 of the block main body A, which is stacked in a row and locked together in multiple stages as described above, and the recesses in the left and right ends 11, 12 of the main body Other A to do
18 cement mortar is injected and filled all at once from the hole in the body of the top layer A, which is stacked and locked in multiple stages, through the 17 holes formed by the joints 16 of the recesses on both the left and right ends 11 and 12 of the body. Then, the cement mortar has 10 locking holes, 17 holes, and 7,
It flows evenly into the horizontal reinforcing bar insertion groove 8. and,
15 locking pins, inserted and connected reinforcing bars and A
This is a concrete block for construction that has many effects and features, such as being able to harden together with the main body of the concrete block, making it easy to construct solid, strong, and uniformly strong structures.
