Block for construction, panel for construction using the block, and method of molding panel for construction

Abstract

A block (10) for construction capable of constructing a flat structure by arranging the plurality of blocks in a flat state with four outer peripheral surfaces thereof, that are, an upper surface (10a), a lower surface (10b), a left side surface (10c), and a right side surface (10d) brought into contact with each other. In the block (10) for construction, a plurality of through holes (11) for inserting bar-like stretching members therein are formed parallel with the front surface (10f) and the rear surface (10e) thereof, and recessed parts (12) are formed in the upper surface (10a) and lower surface (10b) forming outer peripheral surfaces crossing the axial direction of the through holes (11) to dispose the other stretching members in a direction three-dimensionally crossing the stretching members inserted into the through holes (11). By using the block (10) for construction, the flat structures such as the wall parts and floor parts of a building can be easily constructed in a rather short period, and the durabilities of these flat structures can also be increased.

Description

technical field [0001] The present invention relates to a technique for constructing a planar structure such as a wall portion, a floor portion, or a ceiling portion of a reinforced concrete building. Background technique [0002] Conventionally, when constructing structures such as walls and floors of reinforced concrete buildings, a method of assembling a concrete sand box at a construction site, arranging steel bars in the sand box, and then pouring concrete has been used. [0003] However, this casting-in-place method requires a lot of labor and time in various processes such as assembling the sand box, pouring the concrete, curing and curing the concrete, and thus becomes an obstacle to shortening the construction period. In addition, in each of these steps, specialized skilled workers are required. [0004] In addition, since the loading, assembling and concrete pouring of sand box materials and reinforcing steel materials require a wide work area, the workability is ...

AI Technical Summary

Problems solved by technology

[0008] The laminated concrete block described in Patent Document 1 can accurately and reliably laminate the blocks by using the connecting pin member, but since the connecting pin member must be arranged on all the boundaries between the adjacent blocks in the vertical direction, Therefore, such an operation requires a lot of labor and time.

[0009] In addition, since these connecting pin members are not members that draw and fix the blocks together, if a tensile force in the axial direction of the connecting pin members is applied to the boundary between the blocks after the laminated construction, there is a possibility that the masonry may be damaged. blocks will separate

Therefore, it is generally suitable for structures such as walls, fences, and foundations that only apply a compressive force in the axial direction of the connecting pin member, and is not suitable for structures that may apply external forces in the deflection direction, such as the floor of a building.

[0010] On the other hand, in the construction method of a block wall described in Patent Document 2, while bonding the joint surfaces of a plurality of concrete blocks arranged vertically and horizontally with an adhesive, inserting and fastening steel rods for tension , to form a flat plate of blocks, but since the insertion of the tension steel rod is the joint part of the adjacent blocks, the strength connecting the blocks to each other is weak

[0011] In addition, because the joint surfaces of the blocks are bonded with an adhesive, the adhesive deteriorates or shrinks after a period of time after construction, and the joint parts of the blocks may be separated or gaps may be formed, resulting in lack of durability. sex
