Abstract

PURPOSE:To allow arrangement and structure to be selected according to functional requirements of structures to be formed by a method in which concrete blocks are combined into paralled crosses in such a way that the upper half of the upper beam is projected from the lower beam and also the lower half of the lower beam is projected from the upper beam. CONSTITUTION:Concrete blocks are combined in parallel crosses in such a way that the upper half of upper beams 1 set in parallel is projected upwards from lower beams 2 set at a right angle and also the lower half of the lower beams 2 is projected downwards from the upper beams 1. Furthermore, a truncated pyramid form of legs 3 are formed on the downsides of the crossing parts of both the upper and lower beams 1 and 2. Then, a truncated pyramid form of a recession 4 corresponding to the leg 3 is formed between the upper beam 1 and the lower beam 2. By this, one or multi-layered arrangement and structures meeting to the functional requirements of a structure can be formed by only one kind of concrete blocks.

Description

[Detailed description of the invention] The present invention relates to covering work, foot protection work, lining work, jetty work, diversion work,
Concerning concrete blocks used for floor reinforcement work, bed protection work, and dam work, a pair of parallel upper and lower girders are used, with the upper half of the upper girder protruding upwards than the lower girder, and the lower girder Connected in a grid shape so that the lower half of the girder protrudes downward from the upper girder 1
7. It is characterized in that the lower surface r leg piece of the lower girder is hung down at the intersection of the upper and lower girders, and its purpose is to construct a structure as an aggregate, In this case, a large number of arrangement methods are possible, and the object of the present invention is to provide an improved concrete block arrangement that can be selected to meet the functions required for a structure.

The illustrated example of the present invention will be described below.

A pair of left and right upper girders fllf11 are arranged parallel to each other, and a pair of front ridge lower girders 12+12 are arranged parallel to each other.
1 are connected in a parallel cross shape such that the upper half of each upper girder (11) protrudes above the lower girder (21), and the lower half of the lower girder (21) protrudes downward from the upper girder (1), Both upper and lower digits flll+21
A truncated pyramid-shaped leg piece (3) is suspended from the lower surface of the lower girder (2) at the intersection of the lower girder (2), and a truncated pyramid-shaped leg piece (31i1C corresponding to A concave cavity (4) is formed.

Figures 6 to 11 show examples of structures constructed by assembling concrete blocks FA as described above. The upper girder of each adjacent block (At (11) , and lower digit 1
The free end faces of 2++21 are arranged so as to abut each other.

Therefore, when the present invention is applied to concrete blocks where water flows, the surface roughness of the block assembly is II.
It is a major element in the function of built structures. Therefore, when a block with a part of the upper girder (1) protruding upward is arranged in running water like this block and the block assembly lII structure is oval-shaped, IIjl! [The surface roughness of an object is determined by the height, number, and area of the protrusions in the direction of water flow; The roughness becomes smaller.

When this block is arranged so that the longitudinal direction of the upper girder ill and the water flow direction are perpendicular to each other, as shown in Fig. 12,
The area of the protrusion of the Glock in the direction of water flow is as shown by diagonal lines. Also, as shown in Fig. 15, the same block is 90
When rotated and arranged so that the longitudinal direction of the lower girder (2) is orthogonal to the water flow direction, the area of the protrusion of the Glock with respect to the water flow direction is as shown by the diagonal line.

Therefore, if the VC blocks are arranged in the direction of water flow as shown in FIG. 12, the roughness will be large, and if they are arranged as shown in FIG. 15, the roughness will be small. Therefore, for example, as shown in FIG. 7, one IC block (A'
It is possible to change the surface roughness by colliding each free end surface of the upper girder ill and the lower girder (21) with the lower girder (21 parallel) (each free end surface r of the upper girder (11) of the adjacent block fAl. In this way, by changing the orientation of the Vr block by an appropriate number, the surface roughness of the block assembly body can be adjusted, and there is no need to use a deformed type Glock like in conventional concrete blocks of this type. Eliminate the complicated work involved in manufacturing a deformed model 1. Also, cut out the protruding parts.
As in the case of using a smaller or modified type, the weight of the block becomes lighter, and there is no tendency to cause defects such as instability against the same external force. In addition, according to this block, there is no need to drastically change the block arrangement method in order to adjust the surface roughness, and therefore, unlike conventional methods of this type, the arrangement can reduce the number of blocks by one block in a plane. If changed, W: There is no risk that the integrity of the structure will be impaired or that the function of preventing the river bed below the covered surface from flowing out will be adversely affected.

Note that the above method is also applied to the case of a block assembly [4 items] having meshing, which will be described later.

Figure 8 shows the case where it is applied to covering work that requires interlocking between blocks in a single layer structure, single layer IIk foundation hardening work, method III, floor hardening work, bed protection work, etc., and each row is adjacent to the other. block (
~ are arranged so that the free end surfaces of the upper girder (11) are in contact with each other, and a recess formed between the upper girder fil in each block (f) and the protruding end of the lower girder +21 + 21 of the orthogonal pair fal'l, insert the protruding end of one lower girder 121 of the block (A') in the adjacent row into the same recess (a) of the Glock (A) in each row, and of-
Each side of the protruding end of the lower spar +21t21 and the protruding end of the lower spar t21+21 of the Glock (~).

There are ↑ things I have saved.

Figure 9 shows a case where the concrete block of the present invention is applied to a single-layer structure in which meshing between Glocks is particularly important. In addition to ((a), there is a recess formed between the lower girder (21) and the protruding end of the upper girder (1) of the pair perpendicular to the lower girder (21). recess f
The protruding end of the upper girder (1) of each block (n) fits into the recess (b) of the block (~) adjacent in the front and rear direction, and the protruding end of the lower girder (2) of one of the blocks 1. Each block (~
are meshed in two directions: front-rear direction and left-right direction.

Figure 10 shows a case in which the concrete blocks of the present invention are applied to structures such as foundation work, floor work, and dam work that are multi-layered and require interlocking in one direction between the lower layers. , the upper half of the upper girder fi+ protrudes above (2) the lower girder (2), thereby creating a recess fcl formed between the upper surface of the adjacent upper girder flH11 and the lower girder (21 (2:
(Using the recess (d) formed between the upper surface of the protruding end of each lower spar 121121 of the arranged adjacent Glocks and the opposing upper spar fllfll, block (the lower digits that correspond to each other +21+21

fa) It is for masonry / locking so as to be placed on top of c.

Furthermore, Fig. 11 shows structures such as jetty construction, conductor R% control, under dam, etc., which have a multi-layered structure and require two-way engagement between upper and lower layers (cases in which the concrete glock of the present invention is applied). - Twin upper spar (llfll and lower spar (2) (2) and the recess (4) formed between them and the adjacent Glock (A117)
Each - twin lower digits +21121. It utilizes the recess (e) formed between +21 and +21, and the /lock f of the first stage
Arrange the end faces of each lower girder (2) (2) of the Alt adjacent block to face each other, and make the upper block (A') of 7
The seven leg pieces (3) are arranged so as to fit into the recesses (4) and recesses (el) of the lower Glocks 1 to 1 through rotation.

At this time, since the lower half of the lower girder (2) protrudes downward from the dowel girder (11), the protruding part of the block (A') installation (upper girder 11) is placed above the block (N). The masonry of the girder (11r) was carried out without any hindrance, and the lower half of the lower girder (2) of the block (2) was secured to the upper half of the block (~). , upper and lower Glock (A) (
At, these mesh more reliably.

As described above, in the concrete/rock according to the present invention, since the upper and lower girders of each pair parallel to each other are connected in a parallel cross-shape, the space between the upper girder and the protruding end of one pair of lower girders, and the lower girder are Between the girder and the upper girder protruding end of the pair, engagement recesses are formed for the lower girder protruding end and the upper girder protruding end of the adjacent concrete blocks, so these recesses can be used to
One-way or two-way interlocking concrete/structural assembly beak structures are constructed.

In addition, the concrete glock related to the unexploded #J (in the above-mentioned [7 Tayo 5] parallel girder shape (the upper half of the combined upper girder is L direction f than the lower girder, and the lower half of the lower girder protrudes downward from the upper girder) Therefore, each of the lower girders and each opposing girder of both blocks combined so that the upper surface of the upper girder and the lower girder of the twin pairs, and the end faces of the protruding parts of the lower girders of the twin pairs are opposite to each other. A space for retaining the leg piece of the upper block is formed between the upper girder (and a recess for retaining the upper block is formed between the upper girder and the lower girder of each of the above-mentioned pairs). Recess and retention space
By simply changing the orientation of each block in the upper and lower layers, a multilayer block assembly structure is constructed in which each block interlocks in one direction or two directions, and at the same time, the stacking height can be adjusted.

Also, by simply changing the orientation of a part of the concrete blocks of the present invention, you can assemble the blocks*1ttt, using deformed blocks (or easily VC without changing the arrangement method).
I can do section J4.

As described above, the concrete block according to the present invention (according to the concrete block of the present invention) is the only type of Glock compared to the conventional concrete blocks of this kind, and can be used to construct structures and [2] single-layer and multi-layer array structures that are compatible with the required functions. Also, without using deformed blocks or changing the arrangement method, the surface roughness of the structure can be adjusted by simply changing the orientation of the blocks. When building a multi-layered structure, it is possible to adjust the surface roughness of the structure by simply changing the orientation of the blocks. By changing the orientation, the upper and lower layers can be interlocked in one direction or in two directions, and the stacking height can also be adjusted at the same time, which has many advantages.

Although the present invention has been described above with reference to practical examples, the present invention is of course not limited to such practical examples, and can be modified in various designs.
