Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a floor panel installed on a veranda or the like of a house.

2. Description of the Related Art Conventionally, it has been known to install floor panels on floors such as verandas, balconies, terraces, and corridors of houses. This type of floor panel has excellent water resistance and durability
It is often made of synthetic resin such as FRP, and also has drainage channels and water collection channels that lead to the drainage channels, and enhances the waterproofness of the floor surface by guiding rainwater etc. to the vertical gutter through these channels. I'm supposed to get it.

And, conventionally, a floor panel integrally molded to a dimension corresponding to the width and width of the floor surface such as a balcony, or a floor panel having a lateral dimension by fastening a short-sized floor panel with bolts or the like on the floor surface. They were placed and fixed to the floor with a curing type adhesive or bolts.

[Problems to be solved by the invention] On the other hand, the veranda of detached houses and apartment houses has a width of 500 mm.
There are various types, from a narrow one to a wide one with an output width of about 1.5 to 2 m, and the width also generally varies within a range of about 1.5 to 15 m.

However, if the floor panel is fixed to the floor surface with an adhesive or bolts as described above, if the floor panel has a length of about 2 m or less, even if it can absorb expansion and contraction due to changes in temperature, the width is When a floor panel longer than that is fixed, expansion and contraction of the floor panel is not reliably absorbed, and there is a problem in that cracks and flexures and gaps around the floor panel are likely to occur.

The present invention has been made in view of the above problems, and by providing the floor panel itself with a function capable of absorbing the expansion and contraction, even if the width is long, cracking and bending accompanying expansion and contraction, a gap around the floor panel. The object is to provide a floor panel that is less likely to cause such problems.

[Means for Solving the Problems] The floor panel of the present invention is configured by connecting panel members installed on the floor surface of a veranda or the like without fixing with screws or the like, and the panel members are connected to each other at a connecting portion. A sealing material for maintaining watertightness is interposed between the overlapping ends of the movably stacked panel members so as not to be exposed on the surface.

[Operation] According to this configuration, if the overlapping end portions of the panel members are overlapped with each other and a plurality of panel members are connected to each other, the width of the floor panel becomes longer according to the number of connected panel members, and thus a veranda having a long width or the like. You will be able to install floor panels on the entire floor surface. The width of the floor panel can be adjusted to the width of the floor by adjusting the number of connected panel members.

And the expansion and contraction of the floor panel due to changes in temperature can be expanded and contracted freely because it is not fixed to the floor surface, but the overlapping ends of adjacent panel members must move relative to each other across the connecting part of the panel members. Absorbed by.

[Embodiment] FIG. 1 is a plan view of a floor panel A according to an embodiment of the present invention,
FIG. 2 is an enlarged vertical sectional view of a main part of the floor panel A, and FIG. 3 is a sectional view taken along the line III-III in FIG.

The floor panel A is configured by connecting a plurality of panel members, and has a stepped edge portion 11 that is erected around the periphery.
While having a drainage groove 12 along one side thereof, the drainage port 12a is provided at both ends of the drainage groove 12, while a large number of places and flat portions along the remaining three sides. A water collecting groove 13 is provided, and all of the water collecting grooves 13 communicate with the drainage groove 12.

The panel members include one end panel members A ₁ and A ₂ disposed at left and right ends of the floor panel A and one or a plurality of intermediate panel members A ₃ disposed therebetween. Divided. Each panel member A ₁ , A ₂ , and A ₃ has a uniform uneven pattern as shown in FIGS. 1 and 3, and a part of the uneven pattern is implemented. The formed recess is used as the water collecting groove 13. The panel members A ₁ , A ₂ , A ₃ are preferably formed by molding a thermoplastic synthetic resin such as vinyl chloride resin by a known technique such as vacuum molding or pressure molding, or by molding by FRP or the like.

Left end panel member A ₁ and middle panel member A ₃ , middle panel member A ₃ and right end panel member A ₂ and one of unillustrated connecting portions of middle panel members A ₃ and A ₃ The first connection structure M shown in FIG. 2 is adopted for the part,
The second connection structure N is adopted in the other part.

The first connection structure M is, for example, an intermediate panel member on one side.
Superimposing the other side of the intermediate panel member A overlaps end 22 formed at the other end of the ₃ adjacent thereto and the overlapping end portion 21 formed at one end of the A ₃ mutually, and overlapping end portions thereof 21,2
The two are bonded together in a watertight state with an adhesive having a watertight sealing function. At a place where the width of the floor is long like a balcony with a long width, a plurality of intermediate panel members A ₃ ...
The intermediate panel members A ₃ ... Are all formed with the above-mentioned overlapping end portions 21 and 22 at one end portion and the other end portion, respectively. When the previously formed at reduced side of the intermediate panel member A ₃ of the overlapping end portions 21 only the thickness equivalent of the intermediate panel member A ₃ of the other side as shown in FIG example, both of the overlapping ends 21 The upper surfaces of both intermediate panel members A ₃ and A ₃ are connected to each other when they are overlapped and joined to each other in a substantially planar manner, which disturbs walking, makes the appearance unpleasant, or promptly drains water. There is an advantage in that a step that hinders the above-mentioned phenomenon does not occur in the connection portion. The edge portion 11 also has a similar connection structure.

The second connection structure N is, for example, an intermediate panel member on one side.
Superimposing the other side intermediate panel member A and the other end portion overlapping end 3 formed on the _third adjacent thereto and overlapping end portion 21 formed at one end of the A ₃ movable relative, the overlapping end portions 21,3
A sealing material 4 for maintaining watertightness is interposed between the two so as not to be exposed on the surface. More specifically, the overlapping end portion 3 of the intermediate panel member A ₃ on the other side is formed by a flat extending portion 31 and a receiving portion 32 adhered to the back surface of the extending portion 31. The overlapping end portion 21 is inserted into the gap 33 formed between the overlapping portion 21 and the receiving portion 32, and the sealing material 4 held by the groove-shaped portion 34 at the tip of the receiving portion 32 comes into close contact with the overlapping end portion 21. And when both overlapping ends 21 and 3 move relative to each other, the sealing material 4 and the overlapping ends
It is designed to slide on the back surface of 21 while maintaining water tightness. Of course, the edge portion 11 also has the same connection structure. Here, the extending portion 31 has the same shape as the overlapping end portion 22 described for the first connecting structure M. Therefore, the overlapping end portion 3 used in the second connection structure N can be formed only by using the intermediate panel member A ₃ having the same shape and providing the receiving portion 21. Therefore, all the intermediate panel members A ₃ can be formed in the same shape with the same mold, and the receiving portions 21 can be fixed with an adhesive as needed, so that the versatility of the intermediate panel members A ₃ is improved.

The sealing material 4 includes hard rubber, sponge rubber, soft rubber,
Although soft plastic, water-swellable rubber, etc. can be used, especially when the sealant 4 made of water-swellable rubber is used, the sealant 4 is dried and shrunk when connecting the panel members. Since the floor panel A can be stored, the connection work is easy, but when the floor panel A is actually used, rainwater is absorbed and the sealing material 4 expands, which improves the watertight sealing property, which is advantageous. The sealing material 4 may be adhered to the groove portion 34 or the like with an adhesive. Even if the sealing material 4 is made of rubber or sponge, the sealing material 4 is in contact with the end portion so as not to be exposed on the surface, so that there is no risk of deterioration and the watertightness can be maintained for a long period of time. As shown in an enlarged view in FIG. 2, if the angled portion is removed from the tip of the extending portion 31 and the tip 31a is formed to have a rounded shape, the tip 31a may be cracked. Not only is it less likely to occur, but molding is also easier. This also applies to the overlapping end portion 22.

The above-mentioned two types of connection structures are arbitrarily distributed to a plurality of connection portions that are generated when panel members such as the end panel members A ₁ and A ₂ and the intermediate panel member A ₃ are connected to form a floor panel. Applied. For example, when the floor panel A is installed on the floor surface of a wide veranda having a width of about 900 cm by using a relatively small width panel member having a width effective length of about 90 cm, the first connection structure M is connected to the left end portion. It is applied to the connection between the intermediate member A ₁ and the intermediate member A ₃ and the connection between the right end panel member A ₂ and the intermediate panel member A _3, and the remaining six intermediate panel members A ₃ ... A total of five panel members of a set of two sheets are manufactured by connecting with the first connecting structure M, and these are connected with each other by the second connecting structure N to form one floor panel A having a width of about 900 cm. It is possible to configure.

Then, this may be simply placed on the floor of a wide veranda of about 900 cm without being fixed with nails or screws.

If the wide floor panel A is constructed in this way,
In the connection part to which the connection structure N is applied, since each panel member A ₁ , A ₂ , and A ₃ is not fixed to the floor surface, it freely expands and contracts, but the relative movement of the overlapping end parts 21 and 3 causes the floor to move. The expansion and contraction of the panel A is absorbed. Therefore, no matter how long the width of the floor panel A is, by providing the second connection structures N at appropriate intervals, it is possible to reliably prevent the floor panel A from being cracked, bent, or having a peripheral gap. be able to. Also,
Floor panel A by increasing the number of intermediate panel members A _3.
Since the width of the floor panel A can be shortened by decreasing the number of intermediate panel members A _{3 on} the contrary, the width of the floor panel A can be reduced to the width of the floor surface such as a veranda. The width of can be easily adjusted.
Furthermore, if the lateral width of each panel member is set to 1 to 2 m or less, it is easy to integrally vacuum-form the panel member, which helps to reduce the cost of the floor panel A as a whole.

Modifications of the second connection structure N are shown in FIGS. 4A to 4D.

In the case of FIG. 4A, a groove portion 23 is formed at the tip of the overlapping end portion 21, the sealing material 4 is held in this groove portion 23, and it is formed by the extending portion 31 and the receiving portion 32. The sealing material 4 is inserted into the gap 33 between the overlapping end portion 3 and the sealing material 4 and is brought into close contact with the back surface of the extending portion 31.

The one shown in FIG. 4B is a combination of the second connection structures N described in FIGS. 2 and 4A. According to this, since the double sealing is performed by the two sealing members 4, 4, more reliable water tightness is maintained.

In the case of FIG. 4C, the sealing material 4 is held on the back surface of the extending portion 31 over two lines, and the overlapping end portion 21 inserted into the gap 33 between the extending portion 31 and the receiving portion 32 seals them. The material 4 is closely attached.

In the case of FIG. 4D, the overlapped end portion 21 in which the extending portion 31 and the receiving portion 32 each hold the sealing material 4 over two lines and is inserted into the gap 33 between the extending portion 31 and the receiving portion 32 is shown. The sealing material 4 is closely adhered to.

FIG. 3 shows a state in which the floor panel A described above is installed on the floor surface of the balcony. In the case of a detached house, plywood is generally used for the floor material 5 of the veranda, but the floor surface may be made of concrete. The floor panel A is disposed on the floor material 5, and a drainer 6 is disposed around the floor panel A. In this example, the draining member 6 is fixed to the handrail 7 or the sill 8 at a position slightly raised from the floor panel A, and all rainwater and the like flowing down the floor panel A is fixed to the floor panel A.
Can be received at Rainwater received by the floor panel A is collected in the drainage port 12a through the water collecting groove 13 and the drainage groove 12, and is drained through a vertical gutter (not shown). In addition, 14 is a perforated plate which covers the drainage port 12a, 7 is a handrail, 8 is a sill provided at the boundary between the room and the balcony, and 9 is a beam.

In the case of FIG. 3, when the floor panel A is simply placed on the floor material 5, the floor panel A is locally bent when walking on the floor panel A, and the floor panel A tends to become ridiculous. To prevent this, the floor panel A may be bonded to the floor surface with a so-called velcro tape, which is a type in which butyl rubber-based adhesive or fibers that are hard to completely cure even with time are entangled and bonded. Also, since the panel members A ₁ , A ₂ , and A ₃ are relatively narrow, the function of the adhesive or the magic tape does not impair the expansion and contraction absorbing function of the second joint structure N described above. In the portion to which the first connection structure M is applied and the portion to which the second connection structure N is applied, a groove 51 is formed in the floor material 5 as shown in FIG. It is desirable to allow 21,3 expansion and contraction.

5A to 5D show an example in which the floor panel A placed on the floor material 5 is pressed by the water draining member 6 so as not to move, without using a butyl rubber adhesive or a magic tape.

In FIG. 5A, the horizontal portion 11a of the edge portion 11 which is raised in a stepwise manner around the floor panel A is pressed by the lower end portion 61 of the draining member 6 fixed to the handrail 7 or the like. The lower end 61 of the draining member 6 may be made of soft resin.

In FIG. 5B, the draining member 6 is integrally formed on an aluminum edge frame 10 provided on a veranda or the like, and the upper edge 11b of the edge portion 11 is pressed by the draining member 6.

In FIG. 5C, the upper edge 11b of the edge portion 11 is pressed by the draining member 6 fixed to the handrail 7 or the like.

According to the configuration described in FIGS. 5A to 5C, the floor panel A
Is sandwiched between the floor material 5 and the draining member 6, so that the floor panel A is not easily displaced even if it is not joined to the floor material 5, and is also expanded and contracted (indicated by an arrow X in the figure). .)
Is absorbed. With these configurations, since it is not necessary to join the floor panel A to the floor material 5, the construction can be performed easily and inexpensively, and the floor panel A can slide freely with respect to the floor material 5. When compared with the case where the floor material 5 is joined to the floor material 5, the above-described second connection structure N and draining member 6
The expansion and contraction of the floor panel A is more surely absorbed in the pressing portion due to.

The one shown in FIG. 5D has an inverted U-shaped engaging piece 101 around the floor material 5.
The stopper 100 having the above is started up, and the upper edge 11b of the edge portion 11 is
Is engaged with the engaging piece 101 of the stopper 100, and the draining member 6 extends to a position where the stopper 100 is covered.
According to this configuration, the stopper 100 has elasticity in the arrow Y direction, and the elasticity not only absorbs the expansion and contraction of the floor panel A, but also the engaging piece 101 of the stopper 100 and the floor member 5. The floor panel A is clamped between the floors so that it is not easily displaced. Therefore, the floor panel A does not have to be joined to the floor material 5, and by doing so, the expansion and contraction absorbing action by the second connection structure N equivalent to that described in FIGS. 5A to 5C is exhibited. Moreover, when the floor panel A is installed, the elasticity of the edge portion 11 of the floor panel A and the elasticity of the stopper 100 are used to move the edge portion 11 of the floor panel A inside as shown by the phantom line in the figure. Using the repulsive force from the state of being warped to the engaging piece 101
It can be fitted into, and workability is improved by doing so.

FIG. 6A shows a draining corner member 62 installed on the corner portion of the floor panel A and a draining member installed on the side portion of the floor panel A.
63 is shown. The straight draining member 63 installed on the side portion of the floor panel A has the same configuration as the draining member 6 shown in FIGS. 5A to 5C. The draining corner member 62 is similar to the draining member 6 in that it includes a mounting portion 62a, an overhanging portion 62b, and a hanging portion 62c, but is different in that the hanging portion 62c is curved in an arc shape. There is. In this way, if the hanging part 62c of the draining corner member 62 has an arc shape,
When installed around the floor panel A as shown in FIG. 6B, the hanging part 62c is arranged along the curved corner portion A ₄ of the floor panel A. Therefore, the protruding width H ₁ of the draining corner member 62
62f and floor panel A
It is possible to secure a relatively large distance H ₂ from the corner portion A _{4 of} . This means that even if the corner portion A ₄ is displaced inwardly due to the contraction of the floor panel A, the displacement is surely absorbed by the gap H ₁ , which improves the appearance. Leads to. It should be noted that such an advantage becomes more apparent by comparison with that shown in FIG.

FIG. 7 shows that the corner portion A ₄ of the floor panel A is drained by only the straight draining member 63 without using the draining corner member 62. This is one in which the water draining members 63, 63 are made slightly longer, the ends thereof are cut at 45 degrees and abutted at right angles, and the abutting points 64 are joined by an adhesive having a watertight sealing function. In this case, if the drain width H ₃ of the draining member 63 is the same as the drain width H _{1 of} FIG. 6B, the distance H between the hanging portion 63c and the corner portion A ₄ of the floor panel A is H.
₄ becomes narrower than the interval H _{2 in} FIG. 6B, and when the interval H ₄ is made equal to the interval H _{2 in} FIG. 6B, the projected width H ₃ becomes larger than the projected width H _{1 in} FIG. 6B. And if the interval H ₄ is narrow, when the corner portion A ₄ is displaced inward due to the contraction of the floor panel A, the abutting portion 64 hits the corner portion A ₄ of the floor panel A, and the portion is abutted.
64 opens and the watertight seal of the adhesive is easily compromised. Therefore, there is no choice but to increase the above-mentioned protrusion width H ₃ , which causes the appearance to be deteriorated, and at the same time the drainer 63 to narrow the veranda and the like. In addition, it takes a lot of time to perform a 45 degree cut and the like, so that workability is impaired.

By the way, it is not essential to install the draining member 6 in the present invention, but by installing the draining member 6, a more complete waterproof action is exhibited. That is, if only the floor panel A is installed on the floor surface such as a veranda without installing the draining member 6, rainwater flowing down the handrail 7 and the like will infiltrate onto the floor material 5 and further down through the gap between the floor material 5 and the like. Occasionally, a situation may occur in which it is transmitted to. Therefore, in a detached house, if it is necessary to prevent rainwater from flowing downstairs from the floor material 5 of the balcony, a waterproof sheet may be laid on the floor material 5 or a simple waterproof pan may be installed downstairs. It was installed on the eaves of the (floor) to prevent rainwater from flowing down. However, installing a waterproof sheet or a simple waterproof pan is to perform double waterproofing with a floor panel and a waterproof sheet, and the floor panel A is installed on the floor surface of the veranda.
As a result, extra work and cost are required in addition to the installation of the above, and as a result, the work and cost are generally wasted. Therefore, by omitting the installation of the waterproof sheet or the simple waterproof pan by installing the draining member 6 around the floor panel A as in the embodiment, it is possible to save labor and cost and to achieve a complete waterproofing. The advantage is that

If the surface of the floor panel A of the embodiment is roughened by graining or roughening, the risk of slippage and discomfort during walking can be eliminated, and walking fatigue can be reduced.
Further, if the surface of the floor panel A is subjected to an antistatic treatment, it will not receive an unpleasant electrostatic shock.

[Effects of the Invention] As described above, according to the present invention, not only can the width of the floor panel be increased or decreased according to the width of the floor such as the balcony, but it is also fixed to the floor with screws or the like. The expansion and contraction of the floor panel which is not present is surely absorbed at the connection portion of the panel members constituting the floor panel. Therefore, even when the floor panel is installed on a floor such as a veranda having a long width, it is difficult for cracks and bends due to expansion and contraction of the floor panel and gaps around the floor panel to occur.
