DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a unit type outdoor floor structure to be installed on a veranda or a balcony of a house or the like.

[0002]

2. Description of the Related Art In a general wooden house, when a veranda or a balcony is provided, it is particularly necessary to provide waterproofness and measures against water leakage.

Conventionally, a construction method using a waterproof sheet or the like used for building construction and the like has been generally adopted, but recently, with the progress of plastic molding technology, as seen in urban areas, as shown in FIG. Along with the increase of small houses, a construction method of attaching a box-shaped or tray-shaped waterproof unit in which a veranda unit having an area of about 1 tsubo is integrally formed by FRP has become widespread. This construction method can be factory-manufactured if the dimensions of the veranda or the like are standardized, and has good workability in that no special skills are required for construction, and is economical. In addition, FRP
Is excellent in weather resistance and durability, and is more advantageous in waterproofing by being integrally molded.

However, in a veranda or the like having a relatively large area, molding such a waterproofing unit integrally requires a one-dimensional problem of increasing the size.
Since the weight per unit increases, a crane is required at the time of construction, which causes a problem in workability, especially in transportation work.

[0005] In view of this, there have been proposed split-type and assembly-type flooring materials as shown in FIGS. In this example,
One of the joint portions of the waterproof panels 31, 32, and 33 is formed in an L-shape, and the other is formed in a J-shape so as to serve as a receiving port. One of the L-shaped portions 43 is put on each other, butts each other, a packing 44 is inserted into a space sandwiched between the two portions, and a caulking agent 45 is filled in the upper surface thereof.

As shown in FIG. 9 (d), the mounting screw 46 is fixed to the building 34 in a recess 47 for receiving the head of the mounting screw 46, which is provided separately from the joint. After filling the caulking agent, the cap 48 is used to cover the screen.

[0007]

However, in wooden construction, despite the fact that the wood used as the material expands and contracts,
Since the FRP etc. with different expansion ratios are completely fixed with screws etc., the above waterproof unit etc. can not adapt at all to the expansion and contraction of wood, and all the stress is attached to the fixing means such as mounting screws etc. It will hang. If the structural material of the building expands and contracts and a force is applied in the direction indicated by the arrow in FIG. 9C, the force acts to open the joint surface. Packing materials such as caulking agent, rubber or urethane filled into the joint surface have the property of hardening or deteriorating due to aging, so that the durability of each of the above parts will be significantly reduced, and as a result, the waterproofness will be deteriorated. This was causing water leakage.

[0008] In the wooden construction, since wood, which is a raw material, has a property of shrinking in accordance with the humidity in the air and causing dimensional irregularities, it is desirable that the wood be exposed to sufficiently dry air in the stage of the framing process. By drying it, it is possible to correct some "out of order". Therefore, a resin molded article or the like, such as an FRP product, has an extremely small shrinkage ratio as compared with wood, and it is desirable to fix the resin after such deviation has converged to some extent.

[0009] However, since buildings are constructed throughout the year regardless of the season, houses built during the humid season often have a high degree of "madness" due to subsequent shrinkage.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide an assembling type outdoor floor structure which ensures waterproof durability which is not available in the conventional method.

[0011]

SUMMARY OF THE INVENTION In other words, the outdoor floor structure of the present invention is an outdoor floor constructed in such a manner that a plurality of structural members are juxtaposed vertically and horizontally and combined to form an integrated floor. It is a structure, and the shape of the joint is formed in an L-shape so as to form a U-shaped groove when two adjacent flooring materials abut against each other, and the tip thereof has a right angle to the bottom of the groove. A bonding surface having a desired width is provided, and a U-shaped groove is formed by sandwiching and bonding a plate-like elastic member having a desired thickness on the bonding surface, and an adhesive sheet is formed on the bottom of the formed groove. A plate-like body made of a hard material to be a second waterproof layer is bonded by bonding a plate-like elastic member serving as a first waterproof layer and elastically connecting adjacent floor members together. The floor material unit is integrally formed by bonding At the center of the horizontal member, which has been previously movably locked with the knit being allowed to move slightly in the plane direction to the building main body, two vertical members arranged with a gap suitable for the thickness of the joint are set up. Installed on a bracket provided with a floor material receiving portion between its vertical members, and fixing the floor material unit to the bracket with mounting screws or the like while holding the plate material made of the hard material as a holding member. Over the entire area of the groove, a caulking agent as a third waterproof layer is filled, and the space formed by the floor unit and the building is filled with urethane foam. It is a feature.

[0012]

Since the prefabricated outdoor floor structure of the present invention is constructed as described above, the floor material unit is not directly fixed to the building structural material by the fixing screw, but the mounting bracket which is a finely movable latch serving as a cushioning material is provided. Because of the interposition, it is possible to sufficiently adapt to the expansion and contraction of wood, which is a structural material of a building.

Further, since the joining portion has a structure in which flexible plate-like materials are overlapped, the direction of the stretching force of the wood applied to the flooring material and the direction of the overlapping surface are parallel to each other, and the stretching force is reduced. Since the elastic material is absorbed by the deformation and the displacement of the adhesive surface, the deterioration of the waterproof performance due to aging can be significantly reduced.

Further, the floor unit can be easily positioned by fitting the floor unit to a bracket which is pre-positioned and locked to the building, so that high precision can be achieved without requiring special skill in construction. Construction is possible.

[0015]

An embodiment of the present invention will be described below with reference to the drawings.

In FIG. 1, reference numeral 1 designates a unit of a prefabricated outdoor floor material having a prefabricated outdoor floor structure according to the present invention. FIG.
As shown in FIG. 1, the flooring unit 1 is mainly composed of square panels 2, 3, and 4 having desired shapes, longitudinal members 5 and 6, and a plate-like elastic member 8 corresponding to each joint surface. The square panels 2 and 4 form both ends in the longitudinal direction of a veranda or the like on which the flooring unit 1 is installed.
And 6 form both ends in the width direction. These panels and longitudinal members are preferably made of FRP as a material, and the dimensions of the veranda or the like are generally constituted by a multiple of 0.5. It is appropriately determined so as to match the dimensions of the veranda or the like. In the figure, the panel is composed of three square panels and two longitudinal members. However, it is needless to say that a larger number of panels may be combined depending on the size of the installation place, and the longitudinal members may be further divided. . Note that one of the long members 5 is usually provided with a drain groove 21.

FIG. 3 shows an assembled state. Floor panel 2,
3, 4 and the longitudinal members 5, 6 are formed in an L-shape such that a joint portion 9 abuts two adjacent flooring materials to form a U-shaped groove. A joining surface 7 having a desired width and being perpendicular to the bottom of the groove is provided.

First, the plate-like elastic member 8 is sandwiched and adhered to the joint surface 7 of the panel or member to be joined.
To form a U-shaped groove. Either an adhesive sheet or an adhesive can be used for this bonding.

Next, the adhesive sheet 1 is placed on the bottom of the U-shaped groove.
0, and a plate-like elastic body 11 having a width substantially equal to the width of the groove is pasted thereon. The plate-like elastic body 11 functions as a first waterproof layer and as a connecting member between panels. These plate-like elastic member 8 and plate-like elastic body 1
1 is preferably a neoprene rubber foam or the like.

Then, the plate-like elastic body 11
A hard plate-like body 12 that is slightly smaller than the groove width and serves as a second waterproof layer is attached by an adhesive or an adhesive sheet. It should be noted that the use of the plate-like elastic body 11 and the plate-like body 12 which are bonded and integrated in advance is convenient in construction.

Accordingly, the connection of the panel or the longitudinal member is determined by the plate-like body 12 and the adhesive sheet 10, and the upper surface of the panel and the joining surface are parallel.
Even if any force is applied in the plane direction of the panel, the force is absorbed by the deformation of the plate-like elastic body 11 and the displacement of the bonding surface at the joint surface of the plate-like elastic body 11 and the hard plate-like body 12. Becomes Even in such a case, since there is no gap between the joining surfaces of the plate-like elastic body 11 and the hard plate-like body 12, the waterproofness is kept high. The reason why the width of the plate-like body 12 is made smaller than that of the groove is to prevent the plate-like elastic body 11 from being stretched when the groove width is reduced due to the compression of the plate-like elastic body 11 due to the expansion and contraction of the building structural material 15. .

In this way, a plurality of panels and longitudinal members are juxtaposed vertically and horizontally and connected to form one flooring unit 1, which is fixed to a building structure 15.
The floor unit 1 is not directly fixed to the structure 15, but is provided via a mounting bracket 14 in the middle.

As shown in FIG. 4, the mounting bracket 14 has a vertical member 22 erected substantially at the center of a horizontal member 24 at a desired interval, and a floor material receiving portion 25 is provided therebetween. A screw hole 26 for attachment to the structure 15 is formed in the horizontal member 24 as an elongated hole or a circular hole. Also, the tips 23 of the two vertical members 22 are spread outward on both sides to facilitate insertion of the flooring unit 1.

The mounting structure of the mounting bracket 14 to the structure 15 shown in FIG. 5 is performed as shown in FIGS. That is, these attachments are made by stainless steel screws 16 so as not to rust, but between the head of the stainless steel screws 16 and the mounting bracket 14 via a washer 17 having a diameter sufficiently larger than the diameter of the screw hole 26, and Since the fastening is stopped so that there is a slight gap between the washer 17 and the mounting bracket, the mounting bracket 14 has a screw hole 2 formed as a long hole or a circular hole at the maximum in the surface direction.
The "shift" is allowed by the length or diameter of 6. If an appropriate tightening can be obtained and the mounting bracket 14 is locked so as to be finely movable, a method of interposing a collar or a spacer 17 'as a tightening stopper of the stainless steel screw 16 instead of the washer may be used.

As described above, the mounting bracket 14 is positioned and fixed to the structure 15 in advance, and then the joint 7 of the integrated flooring unit 1 is inserted into the mounting bracket 14.

The space between the flooring unit 1 and the building 15 is filled with a urethane foam 20 for heat insulation and soundproofing. The urethane foam 20 is preferably soft and has a desired space shape. In the process, the urethane foam 20 is installed after the mounting bracket 14 is attached, and then the flooring unit 1 is covered.

In order for the mounting bracket 14 and the floor unit 1 to be positioned to some extent, the floor unit 1
The joint 7 has a U-shaped notch 27 at a desired position, and the floor material receiving portion 25 of the mounting bracket 14 is fitted therein. The depth of the notch 27 depends on the mounting bracket 14.
And the lower end of the joint surface 7 of the floor material unit 1 is in contact with both the structure 15 and the floor material receiving portion 25 of the mounting bracket 14, so that the load is applied to one of the two. It is important not to concentrate.

The floor unit 1 and the mounting bracket 14
Is fixed with a stainless steel screw 18 so as not to rust.

Then, a caulking agent 15 is filled as a third waterproof layer so as to fill the groove on the plate-like body 12. As the caulking agent 15, silicon is generally used.

In this embodiment, three layers are formed in the U-shaped groove as the waterproof layer, but four or more layers may be formed if necessary.

FIG. 8 is a plan view showing an example of the combination of the flooring units 1. (A) shows a 5-piece type, and (B) shows a 3-piece type. In the figure, 28 is a drain port.

The upper surfaces of the panels 2, 3 and 4 and the longitudinal members 5 and 6 may be subjected to non-slip processing such as satin finish to expose the material FRP. May be attached.

Also, the prefabricated outdoor floor structure of the present invention is not limited to a wooden structure, but it is of course possible to cope with any building style such as a reinforced concrete structure and a steel frame structure.

[0034]

Since the prefabricated outdoor floor structure of the present invention is constructed as described above, the flooring unit is not directly fixed to the building structural material by the fixing screw, but is mounted so as to be finely movable as a cushioning material. Since the bracket is interposed, it can sufficiently adapt to the expansion and contraction of wood, which is a structural material of a building.

Further, since the joint portion has a structure in which flexible plate-like materials are overlapped, the direction of the stretching force of the wood applied to the flooring material and the direction of the overlapping surface are parallel, and the above-mentioned stretching force is reduced. Since the elastic material is absorbed by the deformation and the displacement of the adhesive surface, the deterioration of the waterproof performance due to aging can be significantly reduced.

In addition, the structure in which the floor material unit is fitted to the mounting bracket which is pre-positioned and fixed to the building facilitates the positioning of the floor material unit, and achieves high precision without requiring special skill in construction. Construction is possible.
