Description

  The present invention relates to an intermediate unit block body that is assembled at an intermediate stage portion of a civil engineering building block, and more specifically, a unit block body for a rectangular parallelepiped is firmly connected vertically and horizontally by a connecting member to form a single row in a plurality of stages. And / or a building block for civil engineering and building with a modular modular shape with a standard shape so that a wall structure of an arbitrary shape can be easily constructed by freely arranging and assembling it in multiple rows or cross rows. The intermediate unit block body.

  Conventionally, in the wall structures for various civil engineering buildings, a concrete block body made of a concrete molded body has been used. Construction using such a concrete block body is relatively easy to transport and handle, and can be manufactured and manufactured. Widely used for efficient construction.

  For example, it has a masonry structure that builds a wall structure by building bricks while sequentially adding outer pipes and inner pipes inserted into through holes formed in bricks that are block bodies to form a reinforcing core. A construct is disclosed in US Pat.

  Also, a plurality of concrete blocks are assembled together in advance or integrated into one end in the wall direction at the lower end of the panel body, and a connecting projection protruding upward is installed in a previously excavated groove, and thereafter A connecting member having a connecting hole is provided at one end in the wall direction at the lower end of the panel body to be installed, and the connecting hole is inserted into the connecting hole in a state where both panel bodies are installed at predetermined positions. The guide rod lower end inserted into the connection hole is connected to the connection projection upper end, and the connection hole and the connection projection are fitted using the guide rod as a guide, and the lower ends of both panel bodies are connected to each other. Patent Document 2 discloses a basement method for constructing walls that are connected to each other.

  In addition, a plurality of concrete blocks in which a cable communication hole and a connecting rod insertion hole are formed are formed by a pair of connecting members including a connecting rod in which a male screw is formed and a nut portion in which an engaging portion is formed. A concrete block connecting structure (cable joint groove) configured to be connected is disclosed in Patent Document 3.

  Further, as shown in FIG. 7, a plate-shaped face plate portion 112, and a locking column 114 that protrudes in the right and left sides at one end of the face plate portion 112 and protrudes in a direction perpendicular to the surface of the face plate portion 112, The pair of unit members 110 face each other on the surface of the face plate portion 112 on the side from which the locking column 114 protrudes, and the unit member 110 on the opposite side of the locking column 114 is used. Patent Document 4 discloses a bank protection block 120 that is formed by overlapping and integrally joining the face plate portions 112 so that a gap G into which the locking pillar 114 can be inserted is interposed therebetween.

  Further, a combined building block is constructed in which a construction block is constructed by stacking a plurality of building blocks each having an occlusal protrusion and an occlusal recess formed symmetrically on the upper and lower surfaces so as to engage the occlusal protrusion and the occlusal recess. However, Patent Document 5 discloses a united stacking block formed by combining a plurality of parts obtained by disassembling a united stacking block at a predetermined position and combining and fixing a plurality of parts.

  However, in the structure having the masonry structure described in Patent Document 1, bricks inserted through the reinforcing cores standing in the vertical direction are basically built up to form a single row of wall bodies. For example, there is a problem that the degree of freedom and strength of the design are lacking, such as the inability to form a plurality of rows of stronger walls that are also connected to each other in the lateral direction.

  Moreover, the basement construction method which comprises the wall body of patent document 2 is, after installing a panel body in an excavation groove first, concrete is poured into a panel body from the top, and the placed concrete is a panel body. It flows out from the lower end and forms a root tangle and is fixed. When inserting the panel body to be subsequently inserted, the guide bar is inserted in advance into the connecting hole from above, and the panel body is lowered along the guide bar in a state where the projecting portion at the lower end is fitted and fixed to the projection. The connecting holes are automatically fitted into the protrusions so that the lower ends of both panel bodies are connected to each other. Such a construction method is complicated, requires a long construction period, requires specialists for assembling, and costs labor, which increases costs and places concrete in the case where a wall is not required. Since they are integrated, etc., reuse is difficult, and there is nothing but to crush and dispose of as industrial waste. Furthermore, there is a problem that the connecting member composed of the connecting plate fixed to the back surface of the vertical frame member of the connecting member by the bolt has a complicated configuration and the workability is poor.

  Moreover, since the concrete block connection structure described in Patent Document 3 is basically only connected in a single row and a single stage, it is a multi-stage wall body and a plurality of rows of layers connected in the lateral direction. Since a strong wall or the like cannot be formed, there is a problem that the degree of freedom in design and strength are lacking.

  Further, the revetment block 120 described in Patent Document 4 still has a complicated outer shape such that the unit member (concrete block) 110 includes a locking column 114 that protrudes from the face plate portion 112, so that the concrete molding operation is not performed. Technically quite difficult and time-consuming. In addition, since only a single-row wall body is basically constructed and a plurality of rows of stronger wall bodies that are also connected in the lateral direction cannot be constructed, the degree of freedom in design and strength are lacking, etc. There is a problem.

  Furthermore, the unitary stacking block described in Patent Document 5 has a complicated outer shape such as the building block body is formed with occlusal protrusions and occlusal recesses symmetrically on the upper and lower surfaces. However, it is technically quite difficult and time-consuming. Basically, the single-row wall body is relatively easy to configure, but it is difficult to form a plurality of rows of stronger wall bodies that are also connected to each other in the lateral direction, so that the degree of freedom in design is lacking. And so on.

  Therefore, the present invention has been devised to solve the above-mentioned problems of the prior art, and the object of the present invention is excellent in concrete forming workability at a factory, and reinforced concrete placement or mortar placement at the time of construction on site.
