Description

[Detailed explanation of the idea] [Industrial application field]

The present invention relates to floorboards for buildings that can be laid directly onto the floors of general offices, various classrooms, etc. without shaking.

[Conventional technology and its issues]

Conventional building floorboards, both for general offices and free access, have been square in shape and supported at four points at all four corners. For this reason, with fixed support legs, rattling occurs even when the floor surface is uneven (unevenness, waving), so adjuster bolts are used to level the legs, and shims are used to adjust the rattling. That's what I was doing. A raised floor plate with three-point support on the floor foundation surface to prevent rattling was proposed in Japanese Utility Model Application Publication No. 165732/1982, but since it was simply triangular or close to it, various problems were encountered during construction. This will cause inconvenience. For example, because they are triangular units, they have corners that make them difficult to carry compared to square ones, and the corners are easily damaged, making it troublesome to lay them out. Furthermore, even after construction, the long hypotenuse requires a long support interval, and the need to withstand the concentrated load applied by casters and the like requires great strength, making it a heavy object. In order to create a structure that can withstand this concentrated load, it is possible to provide an auxiliary support at the center of the panel, as shown in Japanese Patent Application Laid-open No. 54-107131, but the corner support and the auxiliary support may have the same length. If the auxiliary support is made shorter than the corner support, the spacing between the supports is likely to increase due to the width of each side of the conventional panel being 465 to 600 mm. Because the area is wide, the height between the pillars is large, so the auxiliary pillars must be set much shorter than the corner pillars, and if the floor surface on which the auxiliary pillars touch the ground is concave, the floor panel may be significantly distorted. This is not desirable.

[Means to solve the problem]

The building floorboard of the present invention solves the above-mentioned difficulties, and has been developed specifically as a lightweight and high-strength floorboard for office automation that can be installed directly on the floor foundation surface. Its structural feature is that a leg body 2 is provided at each vertex of a right-angled isosceles triangular plate body 1, and a leg body 2 of the plate body 1 is provided integrally with the plate body.
In between, an auxiliary leg 8 shorter than the leg is provided integrally with the plate 1, and the plates are flexibly connected to each other so that four or more plates form one square floor plate. Here, the leg 2 that is integral with the plate 1 is not limited to one that is integrally formed of the same material as the plate 1;
It refers to something that is integrally installed by screwing or gluing.

[Effect]

As described above, in this invention, in addition to the legs 2 at each vertex of the triangle, an auxiliary leg 8 slightly shorter than the legs 2 is provided integrally with the plate, and the plates are connected to each other at right angles of four or more plates as a flexible connection. By forming one square floor plate from isosceles triangular plates, leveling and backlash adjustment are completely unnecessary, and the load capacity is increased with almost no increase in weight or cost. That is, in the case of a conventional one-piece rectangular floor panel that is supported at four points, it is generally attached to four support legs because the level and backlash must be adjusted. In addition, as a measure to increase the strength of such square floor panels, it has been known in the past to provide auxiliary legs in addition to the four corner support legs, and to adjust the level in the same way as the four corner support legs (for example, in the Japanese Patent Laid-Open Publication No. 54-107131 etc.). As shown in Figure 8, this invention uses small right-angled isosceles triangular plates as flexible connections to form one square floorboard with four or more plates, thereby shortening the distance between the legs. Since it is possible to reduce the difference in height caused by the unevenness of the floor between the corners, the auxiliary legs need only be set slightly shorter than the legs at the corners, and there is no need to adjust the backlash. It provides floorboards (floor panels). As mentioned above, the size of such a floor panel is 465 x 465 mm ~ 600 ~ 600 mm, and the required strength is a deflection of 2 mm or less under a load of 300 kg, or a deflection of 2 mm or less under a load of 200 kg. Therefore, the length of the auxiliary leg 8 of the present invention is preferably about 1 to 2 mm shorter than the leg at the apex of the triangle. In other words, if the dimensional difference between the leg 2 and the auxiliary leg 8 is small, the auxiliary leg will hit the floor and play when the floor surface on which it is laid is uneven, causing play, and the dimensional difference is too large. When a load is applied to the floorboard, the amount of deflection increases beyond the allowable value, and the upper surface of the floorboard becomes extremely uneven. Therefore, as mentioned above, the dimensional difference is preferably 1 to 2 mm, and the triangular leg body is made smaller than the conventional one. In addition, the present invention combines a plurality of triangular plates having the above structure to form one square floor plate, making it convenient to carry and transport.

【Example】

The present invention will be explained in detail below with reference to illustrative drawings. FIG. 1 is a plan view of a right triangular plate according to the present invention, and FIG. 2 is a front view. FIG. 3 is a bottom view of the same. FIG. 4 is a sectional view taken along the line AA in FIG. 1. FIG. 5A is a partial plan view showing how it is laid on the floor, and FIG. 5B is a bottom view of the same portion. FIGS. 6A to 6D are longitudinal cross-sectional views showing the state of connection between floorboards. FIGS. 7 and 8 are plan views showing examples of combinations of plate bodies. As is clear from these figures, the building floorboard of the present invention is comprised of a right triangular board 1 and legs 2 provided at each vertex thereof. In the example of FIG. 1, the plate 1 is a right isosceles triangle, and when laid, it is possible to form square patterns as shown in FIGS. 5A and 5B, and FIGS. 7 and 8. The legs 2 provided at each vertex are cut from a cylinder so as to match the angles of the respective apexes. The plates 1 can be joined together in various ways as shown in FIG. 6. As shown in Figure 6A, one plate 1 is provided with a groove 3, and the protrusion 4 provided on the other plate 1 is fitted into this to form a tongue and groove joint. As shown in , B, each plate 1 is provided with grooves 5 and 5, and a groove joint is used.Also, as in the case where a triangular plate 1 is made from a square plate, two pieces are made. The floorboards for a building are left slightly joined at the board 1 part, and the part that does not need to be separated is fixed with a cutout 6 whose one end is driven into the board and the other end is fitted into the hole 11. Leave a slight gap between the parts 1 and 1 are in contact with each other, and use rubber adhesive 7 to adhere to this gap. In addition to these methods, the plates can be joined in various ways, such as by using a separate flexible member. In this way, flexibility can be provided between the floorboards. This direct laying floor board for buildings is laid directly on the ground (direct laying)
Although this is the objective of the present invention, it can also be installed at a higher position from the floor using separate support legs. Furthermore, a surface flooring material 10 such as a wide-area carpet or vinyl tiles that are individually divided into small areas can be attached to the upper surface of the plate 1. However, if the board 1 is made of precious wood or decorative plywood, there is no need to paste anything on the board 1. In Figures 2 to 4, when the plate 1 is a single triangular body, there is a
An example of the auxiliary leg 8 that is slightly shorter than the main leg 2 is shown. With such a structure, the legs 2 and the auxiliary legs 8 do not touch the floor at the same time, but the auxiliary legs 8 do not touch the floor until a predetermined load is applied, although this is not directly related to rattling. In other words, when a predetermined load is applied to this auxiliary leg 8, it touches the ground and performs the same function as the leg 2, the leg spacing is 1/2 that of the conventional one, and the amount of deflection is proportional to the cube of the leg spacing. As a result, the amount of deflection of the plate is reduced to 1/8, which ensures safety under high loads.

[Effect of the idea]

Since the direct-laying floorboard for buildings of the present invention has the structure as detailed above, it has the following characteristics. 1. Since the building floorboard has a three-point support and has a basic triangular shape, the three legs are always in contact with the ground and there is no wobbling when it is installed. 2. By providing the auxiliary legs, safety can be ensured during high loads, and materials with slightly higher elasticity can be used for the plates. 3 By making a flexible joint structure of multiple sheets and pasting vinyl tiles, carpet, etc. on the surface, it becomes a rectangular building floorboard, which can be laid in the same appearance as conventional square floorboards. In this case, unlike conventional products, each leg is in contact with the ground regardless of unevenness, so there is no wobbling. Due to the above features, sufficient floor strength can be ensured even with thin and inexpensive materials, making it particularly suitable as a direct-laying floorboard that satisfies the requirements of being inexpensive and easy to install, which is most needed for office automation. It's summery.
