DETAILED DESCRIPTION OF THE INVENTION
Next, a detachable wall surface structure and a wall surface material introducing jig according to an embodiment of the present invention will be described.
[0015]
FIG. 2 is a sectional view of the removable wall surface structure according to the present embodiment. The structure is constructed by stacking construction materials 11, and the detachable wall surface structure has a wall surface material 12 covering a plurality of side surfaces of the structure body, and a wall surface bonding treatment for pulling the wall surface material 12 to the side surface side of the structure. The tool 13 is comprised. One end of the wall surface joining jig 13 is sandwiched between the construction materials 11, and the other end is detachably attached to the wall surface material 12. Moreover, in this embodiment, the compressive adjuster 14 is provided as a shock absorbing material between the wall surface material 12 and the side surface of a structure. The wall material 12 is made of a light-shielding lightweight material such as a resin plate, a thinned wood panel, a siding boat, or the like, and the compressive adjuster 14 is made of a foamed polystyrene plate or the like.
[0016]
The construction material 11 is formed in a substantially box shape as shown in FIG. 3B, in which soil or a substitute thereof is packed in a woven or non-woven sandbag 11a as shown in FIG. Yes. FIG. 3C is a three-view drawing showing the plane, front and side of the construction material 11. As shown in the front view and the side view, the peripheral edge of the construction material 11 has a half of its height H projecting in a semi-cylindrical shape. In addition, when the construction material 11 is loaded vertically in multiple layers, the compressive force F applied to the construction material 11 is supported by a planar pressure receiving portion having a length L and a width B shown in FIG. The
[0017]
When the soil is packed in the soil bag 11a and the compressive force F applied to the soil bag 11a is set to the maximum compression force, the soil inside the soil bag 11a is soiled by the tensile strength T of the cloth material constituting the soil bag 11a. By receiving a reaction force from the bag 11a, the maximum effective restraining stress σ ′ is generated in the soil inside the soil bag 11a. At this time, the ultimate compressive strength Qu of the entire pressure receiving portion of the construction material 11 is obtained by the following equation.
[0018]
Qu = 2 · σ ′ · B · L (1)
In addition, the maximum shear strength τ _f expressed in the construction material 11 by the maximum effective restraining stress σ ′ of the soil in the soil bag 11a is expressed by the following equation, where the internal friction angle of the soil is φ.
[0019]
τ _f = σ ′ · cos φ (2)
Construction ultimate shear strength Qs of the material 11 can be calculated in the same way as the ultimate compressive strength Qu based on the maximum shear strength tau _f. For this reason, based on these ultimate compressive strength Qu and ultimate shear strength Qs, the construction material 11 can display performance related to the compressive strength and shear strength. By displaying the performance of the construction material 11 in this way, when the construction material 11 is used as a support material for the structure, the performance of the structure using the construction material 11 can be displayed, and the structure is objective.

Both ends of the bar 19 are passed through the spectacle holes of the spectacle bolt 16, and therefore, the other end of the tension member 15 is fixed as described above, so that the other end of the tension member 15 is one end of the spectacle bolt 16. Connected to
[0022]
The spectacle bolt 16 is configured such that one end where the spectacle hole is formed is connected to the other end of the tension member 15 and the other end where the male screw is formed is inserted into the hole 12 a formed in the wall surface member 12.

[0023]
FIG. 5 is a cross-sectional view of the wall surface material introducing jig 30 according to the present embodiment. In the figure, the same parts as those in FIG.
[0024]

A female screw 16a into which the male screw 30a is screwed is formed at the other end of the spectacle bolt 16. The wall surface material introducing jig 30 has one end detachably connected to the other end of the spectacle bolt 16 and the length of the spectacle bolt 16 extended by the male screw 30a screwed into the female screw 16a. The wall surface material introduction jig 30 is inserted into the hole 12a of the wall surface material 12 to introduce the wall surface material 12 to the side surface of the structure.
[0025]
In such a configuration, the wall member 12 is attached to the side surface of the structure as follows. That is, the other end of the spectacle bolt 16 is inserted into the hole 12 a of the wall surface member 12, and the nut 17 is screwed to the other end of the spectacle bolt 16 coming out of the hole 12 a through the washer 21. Then, the cap 22 is put on the head of the nut 17, and then the bar 19 is inserted into each spectacle hole of the pair of spectacle bolts 16. Thus, the wall surface material 12 to which the spectacle bolt 16 and the bar 19 are attached is prepared first.
[0026]
Next, when the construction material 11 is stacked to construct a structure, the tension material 15 and the anchor plate 18 are placed on the upper surface of the construction material 11 as shown in FIG. Thereafter, the prepared wall material 12 is placed on the side of the construction material 11. Then, the other end of the tension member 15 is wound around a bar member 19 passed through the spectacle bolt 16 and folded, and further passed under the plate member 20. In this state, the next construction material 11 is stacked on the construction material 11 on which the tension member 15 is placed. Thereafter, the same operation is repeated, and the construction material 11 is stacked, and at the same time, the wall surface material 12 is fixed to the side of the construction material 11.
[0027]
The side surface of the structure covered with the plurality of wall materials 12 in this way is then removed as appropriate by removing the cap 22 and the nut 17 to remove the wall material 12 at a desired location. Eleven situations can be checked.
[0028]
When the removed wall member 12 is attached to the original position after inspection, first, the male screw 30a of the wall member introducing jig 30 is screwed into the female screw 16a of the eyeglass bolt 16 exposed between the construction materials 11. Let Then, the wall surface material introduction jig 30 is inserted into the hole 12 a of the removed wall surface material 12, and the wall surface material 12 is introduced to the side of the construction material 11. Subsequently, the washer 21 and the nut 17 are inserted into the wall surface material introduction jig 30 as shown by the dotted line in FIG. 5, and the washer 21 and the nut 17 are introduced to the side of the construction material 11 in the same manner as the wall surface material 12. Thereafter, the removed wall material 12 is attached to the original position by screwing the nut 17 and the eyeglass bolt 16 together.
[0029]
For this reason, when the detachable wall surface structure is reassembled by using the wall surface material introducing jig 30 according to the present embodiment, the wall surface material is exposed to the side of the construction material 11 and floats without being fixed in position. 12 can be easily attached.
[0030]
Further, according to the detachable wall surface structure according to the present embodiment, each of the plurality of wall surface members 12 is pulled to the side surface side of the structure body by the tension material 15 and is held and fixed to the side surface of the structure body. Further, by attaching and detaching the other end of the spectacle bolt 16 to the wall surface material 12 by the nut 17, the wall surface material 12 is detached from the side surface of the structure independently of the other wall surface material 12.
[0031]
For this reason, each wall surface material 12 can be easily detached from the side surface of the structure body even after the side surface of the structure body is covered with the plurality of wall surface materials 12 by the wall surface bonding jig 13. It becomes possible to easily inspect the inside of the structure. Further, it becomes possible to easily replace the individual wall surface material 12 with a new wall surface material 12 according to the durability performance or breakage of the individual wall surface material 12. Further, by adjusting the length at which the tension member 15 is folded back by the bar member 19 and adjusting the force for pulling the wall surface member 12 to the side surface of the structure by the wall surface bonding jig 13, each wall surface on the side surface of the structure body is adjusted. The position of the surface on which the material 12 is stretched can be adjusted. Therefore, even if distortion or unevenness occurs on the side surface of the structure formed by the plurality of wall surface materials 12, it can be leveled.
[0032]
Further, according to the detachable wall structure according to the present embodiment, the wall material 12 made of a lightweight material is lighter than the conventional concrete block 2 or the like. For this reason, even when recycled products such as polystyrene foam and thinned wood are packed in the soil bag 11a in place of the soil and the construction material 11 is reduced in weight, the construction material 11 that has been reduced in weight is stacked and constructed. Can be used on the side of the body. In addition, the wall surface material 12 can be comprised with heavy materials, such as a concrete board, when not using for such a weight-reduced structure. Moreover, since the wall surface material 12 has a light-shielding property, light does not reach the construction material 11 on the back side of the wall surface material 12, and it is possible to prevent the soil bag 11a constituting the construction material 11 from being deteriorated by light.
[0033]
Moreover, according to the detachable wall surface structure according to the present embodiment, each side portion of the construction material 11 covered with the wall surface material 12 is not uniformly stacked along the side surface of the structure, and the stacked construction material 11 Even if the side surface has irregularities, the irregularities are absorbed on one side of the compressive adjuster 14, and the wall surface material 12 is in contact with the flat other side of the compressive adjuster 14 and pulled on the side surface of the structure. For this reason, the wall surface material 12 can be attached to the side surface of the structure even when the side surface of the stacked construction material 11 is uneven.
[0034]
In the description of the above embodiment, the case where the other end of the tension member 15 is wound around the bar member 19 as shown in FIG. 4 has been described. However, as shown in FIG. Alternatively, the other end may be directly connected to the spectacle hole of the spectacle bolt 16 and connected to one end of the spectacle bolt 16.
[0035]
In the description of the above embodiment, the tension material 15 has been described as a planar net. However, the tension material 15 is not limited to this net. For example, a planar steel sheet or a strip-shaped steel plate, It can also be constituted by things such as wires and round steel. Since the linear material has a small frictional force when sandwiched between the construction materials 11, for example, a collar-shaped anchor plate 42 can be provided at one end like a round steel 41 shown in FIG. preferable. 6A and 6B, the same reference numerals are given to the same or corresponding parts as in FIG. 4, and the description thereof is omitted.
[0036]
Moreover, in the said embodiment, the member inserted into the hole 12a which one end was connected with the other end of the tension | tensile_strength material 15, and the other end was formed in the wall surface material 12 is the surface of the wall surface material 12 from the spectacle bolt 16 and the hole 12a. The case where the nut 17 is used as the locking member that detachably locks the other end of the member projecting to the wall surface 12 to the wall surface material 12 has been described. However, these members and locking materials are not limited to the spectacle bolt 16 and the nut 17. For example, as a member, one end is connected to the other end of the tension member 15, and the other end is inserted into a hole 12 a formed in the wall surface member 12. As a locking member, from the hole 12 a to the surface side of the wall member 12. The other end of the protruding pin can be constituted by a split pin or an E-ring that is detachably locked to the wall surface material 12.
[0037]
Even with each of these configurations, the same effects as those of the above-described embodiment can be obtained.
[0038]
【The invention's effect】
As described above, according to the present invention, each of the plurality of wall surface materials is pulled to the side surface side of the structure body by the wall surface bonding jig and is held and fixed to the side surface of the structure body. In addition, by attaching and detaching the other end of the wall surface joining jig to the wall surface material, the wall surface material is detached from the side surface of the structure independently from the other wall surface materials. For this reason, even after the side surface of the structure is covered with a plurality of wall surface materials by the wall surface bonding jig, each wall surface material can be easily removed from the side surface of the structure body. Can be easily checked. Further, it becomes possible to easily replace each wall surface material with a new wall surface material according to the durability performance or breakage of each wall surface material. In addition, by adjusting the pulling force of the wall surface material to the side surface of the structure by the wall surface joining jig, the position of the surface on which the wall surface material is stretched on the side surface of the structure can be adjusted. The side surface of the structure to be formed can be leveled.
[0039]
In addition, when the wall material is made of a light-shielding light-weight material, the wall material is lighter than a concrete block, etc., so that even when the construction material is light, this construction material is stacked. It can be used for the side surface of a structure that is constructed. Further, since the wall material has light shielding properties, light does not reach the construction material on the back side of the wall material, and the construction material can be prevented from being deteriorated by light.
[0040]
In addition, in the case of a configuration including a cushioning material between the wall surface material and the side surface of the structure, each side portion of the construction material covered with the wall surface material is not uniformly stacked along the side surface of the structure body, Even if unevenness is generated on the side surface of the stacked construction material, the unevenness is absorbed on one side of the buffer material, and the wall surface material is pulled on the side surface of the structure in contact with the other flat surface side of the buffer material. For this reason, the wall surface material can be attached to the side surface of the structure even if the side surface of the stacked construction material has irregularities.
[0041]
In addition, by using a wall material introduction jig that is inserted into the hole of the wall material and introduces the wall material to the side of the structure, when reassembling the removable wall structure, the end is exposed to the side of the construction material. The wall material can be easily attached to a member that is floating without being determined in position.
