Description

  The present invention relates to a base block for providing the height of a flat floor material when laying an elevated floor structure such as a pouch and a terrace deck, and a set of elevated floor structures using the base block.

  In residential construction, a porch may be formed at the entrance or the entrance, or a terrace may be formed at a part facing the garden. Since such a pouch or terrace is set at a position where the top level is higher than the ground level, it is generally constructed by performing tile work while adjusting the level of the placed concrete.

  On the other hand, as an elevated floor structure installed at a position where the top level is higher than the ground level, a wood deck is generally widely used. The construction of such a wood deck is, for example, fixing a plurality of large pulls in parallel on a bundle arranged at predetermined intervals in the vertical and horizontal directions, and placing a plurality of joists orthogonal to these large pulls. In addition, a structure in which a plurality of floor boards are fixed to the upper surface of the joists orthogonally to the joists is generally used (see, for example, Patent Document 1). As a floor board for a wood deck, not only natural wood but also a synthetic resin floor material called synthetic wood has been proposed in recent years. Such resin flooring has good durability compared to natural wood, and has many features such as terrace decks and other flooring materials, and is inexpensive. It is expanding.

JP 2007-2305 A (prior art column)

  In general wood decks, there are abundant designs of flooring materials, but there is a problem that it is difficult to ensure the design properties seen from the side as a high-floor structure.

  On the other hand, the appearance of the tile work is good, but the work of fixing the tile with mortar has a problem that it is generally difficult to remove or replace the tile as a flooring material. In addition, a high level of skill is required for the work of arranging the tiles while adjusting the level of the tiles as floor materials. For this reason, there is a problem that the finished state depends on the skill of the installer.

  Under such circumstances, the number of skilled craftsmen who can reliably perform level adjustment and laying work tends to decrease. Furthermore, the number of craftsmen who are tile craftsmen and who can freely cut out the size of wood and the like is extremely limited.

  Therefore, the present invention has been made in view of such a technical background, and it is possible to select a flooring material having an abundant design to be used for a wood deck while ensuring a design property equivalent to a tile work or the like. An object of the present invention is to provide a high-floor structure excellent in the above.

  In order to achieve this object, the present invention provides a base block for imparting a height to a flat floor material for a raised floor structure installed at a position where the top level is higher than the ground level. The block is composed of a member having a hollow portion in the height direction in which the central portions of the upper surface and the lower surface are opened, and can be arranged at least in the plane direction. The flat floor material is disposed on the upper surface of the base block. A floor mounting hole is provided for fixing the base block, and a connecting groove for connecting between adjacent blocks is provided on each side of the base block upper surface, and a mortar is provided on the upper surface of the base block. A groove is formed, the mortar groove and the connection groove are continuously formed, and the mortar groove is stacked in a state in which joint mortar is filled.

  The floor material mounting hole may function as positioning.

  The depth of the connecting groove is formed deeper than the thickness of a connecting member for connecting between adjacent blocks, so that the connecting groove is a vent in a connected state. Also good.

  The floor material mounting holes may be provided with a plurality of types of mounting holes corresponding to floor materials corresponding to different standards.

  A set of concrete blocks for a high-floor structure according to the present invention is composed of a combination of the base block and a flat concrete block in which mounting through holes are provided at positions corresponding to the floor material mounting holes. It is characterized by that.

  If constituted like the above-mentioned base block, the base block can be provided in a light weight because it is composed of a member having a hollow part in the height direction in which the center part of the upper surface and the lower surface is opened, and after assembly work, It is possible to ensure the design in the side direction equivalent to tile construction.

  In addition, since the floor block mounting hole for fixing the flat floor material is provided on the upper surface of the base block, it is also possible to fix the flat floor material for the wood deck using the floor material mounting hole. it can.

  Further, the enforcement of such a high-floor structure has a feature that it can be easily constructed even by a tile craftsman because the work of fixing the flat floor material for the wood deck is simple.

  Thereby, it is possible to provide a high-floor structure excellent in construction workability that can ensure the design properties equivalent to the wood deck while ensuring the same design properties as tile construction and the like.

  Here, it is preferable that the floor material attachment hole has a positioning function, and each side of the upper surface of the base block is provided with a connecting groove for connecting between adjacent blocks.

  If comprised in this way, if a block is arranged in a plane direction (front-back direction and the left-right direction) and it connects between adjacent blocks by a connection member, level adjustment and block adjustment between blocks can be performed easily and accurately. . Further, if a flat floor material is attached using the floor material attachment holes, level adjustment and street adjustment of the flat member can be performed easily and reliably.

  Moreover, if comprised in this way, since a connection member is used for fixation between blocks, mortar construction becomes unnecessary. Thereby, assembly construction at the construction site is facilitated, and the base block can be disassembled and reused.

  Here, the flat floor material may be directly fixed to the floor material mounting hole, but may be fixed through another member. As such other members, a floor material mounting member provided with a block fixing portion provided at a position corresponding to the floor material mounting hole and a floor material fixing portion for positioning and fixing a flat floor material. Can be illustrated.

  If the depth of the connecting groove is formed deeper than the thickness of the connecting member for connecting between adjacent blocks, the connecting groove is inserted into the block in a state where the blocks are fastened and fixed by the connecting member. It can also be used as a vent for ventilating the outside and outside.

  It is preferable that a mortar groove is formed on the upper surface of the concrete block. This makes it possible to stack concrete blocks in the vertical direction (vertical direction) using this mortar groove, or to use the mortar groove in general and does not have a fixing part to the floor material mounting hole. A flat concrete block can be used as a flat flooring.

  Here, the cross section in the width direction of the mortar groove is free, for example, a semicircular shape, a semi-elliptical shape, an inverted U shape, an acute triangular cross-sectional shape, and the like.

  Moreover, it is preferable that the said floor material attachment hole is provided with the multiple types of attachment hole respectively corresponding to the floor material corresponding to a different specification.

  If comprised in this way, since the flooring attachment hole is provided with a plurality of types of attachment holes corresponding to flooring materials corresponding to different standards, the flooring material having different standards can be used as the base block according to the present invention. Can be fixed on top. Such flooring mounting holes include, for example, flooring mounting holes for mounting square joists made of aluminum for mounting synthetic flooring (flatbed mounting holes), and flat plate mounting for mounting flat concrete blocks A hole is exemplified. Thereby, a synthetic flooring can be constructed and used on a base block, or a flat concrete block can be constructed.

  The base block may be used as a set of concrete blocks for a high-floor structure in combination with a flat concrete block in which mounting through holes are provided at positions corresponding to the floor material mounting holes of the base block. it can.

  According to such a configuration, the flat concrete block is fixed to the upper surface of the base block with a screwing member or the like using the through hole for mounting the flat concrete block and the floor material mounting hole of the base block. Can be adjusted exactly as a concrete block.

  According to such a configuration, since the screwing member is used from the upper surface of the flat concrete block, the mounting through-hole and the head of the screwing member can be visually recognized on the floor board surface after construction, but it is attached from the design site. If the design that takes into account the through hole for screw and the head of the screwing member is performed, the appearance of the deck will not be damaged.

  Also, if it becomes necessary to replace the flat floor material after construction, the flat concrete block can be removed simply by unscrewing the screwing member fixed to the flat concrete block to be replaced. Replacement work is easy.

  Needless to say, other flat floor materials may be used instead of the concrete blocks. Examples of such flat floor materials include tiles, ceramics, and metals.

  According to the present invention, it is possible to provide a high-floor structure excellent in construction workability capable of selecting a flooring material having an abundant design used for a wood deck while ensuring designability equivalent to tile construction.

It is a figure explaining the construction example which fixes a synthetic flooring through the joist of FIG.

  The best mode for carrying out the present invention will be described below with reference to the drawings.

  1 to 4 are diagrams for explaining a base block according to the present invention. In these drawings, reference numeral 10 denotes a base block, and the base block 10 is a substantially square concrete block having a planar shape substantially the same as a general flat concrete block. Here, the base block according to this embodiment is a substantially square of about 30 cm square, and its height is about 10 to 20 cm (for example, 14 cm).

  The base block 10 has a hollow portion 11 in the height direction, and an upper opening 11b and a lower opening 11c that are continuous with the hollow portion 11 are formed on the upper surface 12 and the lower surface 13 of the base block 10, respectively. As shown in FIG. 2, floor material mounting holes 14 and 15 are provided symmetrically at the four corners of the upper surface 12, respectively.

  In addition, a mortar groove 16 having a triangular cross section is formed on each side of the upper surface 12, and a connecting groove 17 crosses each side from the outer wall surface 10 a toward the inner wall surface 11 a at the center of each side. Is provided. The floor material mounting holes 14 (total of four locations) from the corners are flat plate mounting holes for fixing a flat floor material (flat concrete block) 30 to be described later. A total of 8 places) 15 is a joist mounting hole for fixing a joist (floor mounting member) 50 for mounting a synthetic flooring (flat flooring) 40 described later.

  Here, the depth d (FIG. 4) of the connecting groove 17 is not limited, but is about 3 to 5 mm, for example, and is deeper than a thickness t of a connecting member (base connecting bracket 20) described later (d> t). When formed, the difference Δ (Δ = dt) between the thickness t and the depth can be used as a vent hole between the adjacent base blocks 10 and 10 in the connected state.

  Here, the outer wall surface 10a of the base block 10 and the inner wall surface 11a of the hollow portion 11 are parallel to each other in the vertical direction, and the inner wall surface 15a of the joist mounting hole 15 is directed upward as shown in FIG. The diameter D is enlarged.

  As shown in FIG. 4, the inner wall surface of the other joist mounting hole 15 and the inner wall surface of the flat plate mounting hole 14 have substantially the same shape whose diameter increases upward.

Such a base block 10 can be mass-produced easily and inexpensively by a method of producing an instant-removable concrete block which is filled with a concrete block material and is vibrated and compressed as necessary. In this case, as a formwork for manufacturing a concrete block, for example, a bottom mold provided with unevenness corresponding to the connecting groove 17 and the mortar groove 16 on the bottom surface, the hollow portion 11 and the flat plate mounting hole 14, and the joist mounting A core corresponding to the hole 15 is used.
(Example of base block construction)
About the construction example using the base block 10 demonstrated above, the example which lays the flat concrete block 30 on the base block 10 is demonstrated, referring FIGS.

  As shown in FIGS. 5 and 6, the base block 10 is laid out in the plane direction (left and right and front and rear directions) on the laying surface 1 that is substantially flat.

  On the laying surface (ground) 1 to which the base block 10 is grounded, a foundation 2 is constructed with pasamole or the like in which sand, cement and a little water are kneaded. On the other hand, as shown in FIG. 5, plate members (positioning auxiliary members) 3 extending in the longitudinal direction are arranged on the laying surface 1 so as to be orthogonal to each other so as to facilitate street adjustment (horizontal shift adjustment for aligning joints). Set up.

  A plurality of base blocks 10 are arranged along the positioning auxiliary member 3 in the front, rear, left and right plane directions while appropriately performing horizontal adjustment and level adjustment (vertical position deviation adjustment).

  The base blocks 10 and 10 adjacent to each other are fixed by a base connecting bracket (connecting member) 20. The base connecting bracket 20 is, for example, a U-shaped member made of stainless steel having a thickness t of about 1 to 3 mm, and is press-fitted across the connecting grooves 17 and 17 of the adjacent base blocks 10 and 10. The outer wall surfaces 10a, 10a of the adjacent base blocks 10, 10 are elastically pressed and fixed to each other.

  Here, the shapes of the connecting grooves 17 and 17 and the base connecting bracket 20 are arbitrary. For example, the connecting grooves 17 and 17 can be fitted with the base connecting bracket 20 to form the connecting grooves 17. , 17 and the base connecting bracket 20 can be used as positioning members for positioning the relative positions between the adjacent base blocks 10 and 10 when they are connected to each other.

  Next, as shown in FIG. 6, the pasamol located in the hollow portion 11 is brought toward the inner wall surface 11 a of the base block 10, and the remaining space portion 11 is filled with an appropriate amount of crushed stone 4.

  It is also possible to fill the mortar groove 16 with an appropriate amount of the joint mortar 5 and stack the base blocks 10 in the height direction. Thereby, the base block 10 can be stacked in about two or three stages.

By giving moisture to the pasamol, the pasamol is solidified, and the position of the base block 10 is fixed to the laying surface 1.
(Example of construction of commercially available flat concrete block)
When stacking general flat concrete blocks, as shown in FIG. 6, the flat work can be performed by filling the mortar grooves 16 with appropriate joint mortar 5 and stacking the flat concrete blocks 7.

  Instead of the joint mortar 5, it may be fixed with an adhesive 5 such as a bond. Thus, if an adhesive such as a bond is used, the base block 10 without the mortar groove 16 (not shown in the base block according to the modification) can be used.

Thereby, by the effect | action of the base block 10, the top end level of the flat concrete block 7 can be raised rather than the ground level GL, and an example of the high-floor structure which concerns on this invention can be constructed.
(Plate concrete block suitably used in the present invention)
As shown in FIG. 7, as a flat concrete block constituting the above-described base block 10 and a set of concrete blocks for a high-floor structure, as shown in FIG. Used. The mounting through hole 31 is formed at a position corresponding to the flat plate mounting hole 14 of the base block 10.

Such a flat concrete block 30 is filled with concrete block material from above using a mold having a core at the bottom corresponding to the mounting through-hole 31, and is subjected to vibration and compression as needed. It can be mass-produced easily and inexpensively by the manufacturing method of the concrete block.
(Example of construction of flat concrete block according to the present invention)
A screw fixing member such as a nylon resin dip is press-fitted into the flat plate mounting hole 14. The flat concrete block 30 is placed on the base block 10 so that the position of the mounting through hole 31 matches the position of the flat plate mounting hole 14. It is preferable to interpose a cushioning material such as a rubber material (for example, pierced black rubber) between the base block 10 and the flat concrete block 30.

  Next, the flat concrete block 30 is screwed and fixed to the upper surface 12 of the base block 10 with a stainless mounting screw 33. The dip is opened by screwing, and the flat concrete block 30 is securely fixed to the upper surface 12 of the base block 10 as shown in FIG. The top level can be adjusted, for example, by adjusting the number of inserted cushioning materials and the thickness of the cushioning material inserted between the base block 10 and the flat concrete block 30.

  If comprised in this way, since the fixation to the base block 10 of the flat concrete block 30 is screwing fixation, replacement | exchange of the flat concrete block 30 can be performed easily.

  Further, if the depth d of the connecting groove 17 is formed deeper than the thickness t of the base connecting bracket 20 (d> t), the connecting groove 17 is formed in a state where the blocks are fastened and fixed by the base connecting bracket 20. It can also be used as a vent for ventilating the hollow portion 11 of the base block 10 and the outside.

In addition, in the flat concrete block 30 shown in FIG. 8, what has the big through-hole 32 in the center part of the flat plate is used for a part. The through hole 32 is, for example, a through hole for laying a handrail or the like, but is not limited to a handrail, and an appropriate structure can be additionally attached thereto.
(Example of construction of synthetic flooring)
Next, an example in which the synthetic flooring is applied to the upper surface 12 of the base block 10 will be described with reference to FIGS.

  First, FIG. 9 is a view for explaining a joist 50 as a floor material mounting member for mounting a synthetic floor material. In this figure, the joist 50 is constituted by joining four pieces of long members (51 to 54) made of an aluminum extruded product having the cross section shown in FIG. 9 (b) to a rectangular frame.

  The upper surface of each elongate member (51-54) is from the inner side mounting surface 50a used as a flooring attachment surface, the outer side mounting surface 50c, and the hollow surface 50b which became depressed between those mounting surfaces 50a and 50c. A hollow space 56 is formed between the central hollow surface 50b and the mounting surfaces 50a and 50c. Moreover, the lower surface of each elongate member (51-54) is made into the flat block installation surface 50d.

  Each of the long members (51 to 54) has a recessed surface 50b near the both ends (near the four corners of the joist 50) and a block grounding surface 50d at positions corresponding to the joist mounting holes 15 of the base block 10, respectively. Mounting through-holes 55b and 55d (two on each long member, a total of eight). Further, the joist 50 is preferably tapped (not shown) at a position corresponding to a mounting through hole 41 provided in advance in the synthetic flooring 40.

  As a result, as shown in FIG. 10, one joist 50 is placed across the four base blocks 10 in which the adjacent base blocks 10 and 10 are connected by the connecting member 20.

  The tail portion of the stainless steel mounting screw 34 is passed through the mounting through holes 55b and 55d, and the joist 50 is screwed and fixed to the upper surface 12 of the base block 10. A dip (not shown in the drawing is omitted) is opened by the tail of the mounting screw 34, and the joist 50 is securely fixed to the upper surface 12 of the base block 10 as shown in FIG.

  Next, a mounting screw 43 is passed through a mounting through hole 41 provided in advance in the synthetic flooring 40 and screwed to the joist 50. At this time, if the joists 50 are previously provided with taps, the number of construction steps at the construction site can be reduced, and the synthetic flooring 40 can be accurately attached by screwing.

  The top level of the synthetic flooring 40 can be adjusted, for example, by adjusting the number of inserted cushioning materials and the thickness of the cushioning material inserted between the base block 10 and the flat concrete block 30.

  Generally, a commercially available synthetic flooring is a plate-like member extending in the longitudinal direction, and vertical and horizontal dimensional standards do not completely match those of a commercially available flat concrete block.

  However, for example, when a block having a unit size of about 30 cm is used as the base block 10, it is possible to match one or a plurality of base blocks 10 as a unit with a so-called scale module synthetic flooring standard. It becomes possible.

  The embodiment of the present invention has been described in detail above with reference to the drawings. However, the specific configuration is not limited to this embodiment, and design changes that do not depart from the gist of the present invention are not limited to this embodiment. Included in the invention.
