Description

  The present invention relates to a structure of a plate material that can be used for a floor plate or an exterior material of a structure such as a house, and more particularly to a plate material configured so that a desired part of a plate material can be removed after the plate material is attached, and a surface structure using the same plate material. .

  For example, a floor in a building such as a wooden house is formed (floored) by placing a long floor board closely with a fixing means such as a nail or a screw. Usually, with respect to the longitudinal direction of the side walls of these floor boards, a protrusion is formed on one side wall, and a groove is formed on the other side wall. The floor floors are configured so as to be integrated with each other by sequentially fitting the protrusions and the grooves between the adjacent floor boards so that the grooves of the floor boards are fitted.

  In this conventional configuration, the floorboards are fitted together and the floorboards are in close contact with each other so that the entire floor surface is integrated, so that the overall floor surface strength can be maintained high and the floor surface looks good. It becomes. Thus, from the viewpoint of flooring, it can be said that the conventional floor structure is a preferable structure in terms of appearance and permanent use of the floor surface.

  However, in recent years, the lower part of the floor is not merely a space, but is often used for specific purposes such as laying computer cables and various pipes, or arranging a heat source for floor heating. In this case, it may be necessary to check the laying target after the floor surface is formed, such as a heat source check. In this case, in the conventional flooring structure, it is necessary to remove the floorboards that fit each other one after another, and the floorboards are fixed by nailing in many cases. It becomes work to peel off. As a result, the floorboard is damaged, and the removed floorboard cannot be reused. Also, because of the fitting configuration, it is not possible to remove only the portion of the floor plate that is desired to be opened, and the floor plate must be peeled off sequentially from the floor plate at the end of the floor surface to the portion that needs to be opened. As for flooring, the labor, time and cost are huge.

In view of the above-mentioned points, the floorboard structure of the floorboard which can remove the floorboard of a predetermined part of the floorboard, or can be easily removed and reuse the removed floorboard, and the floor structure using the floorboard is described in the following document. Several proposals have been made.
JP 2003-227224 A JP2001-0665165 JP 2006-233705 A JP-A-9-273923 JP-A-9-268745

  First, both inventions described in Patent Documents 1 and 2 are configured such that a specific portion of a long floor board material similar to the conventional one can be removed. Among these, the invention described in Patent Document 1 is configured to fix both side wall portions of adjacent floor boards with screws, and when removing a specific floor board, it is performed by removing a screw for fixing the floor board. . For this reason, it is necessary to previously form a gap for inserting a screw-rotating screwdriver between each floor board, and as a result, the entire floor surface is formed in a “snow-like shape” in which the floor boards are spaced apart from each other by a fixed distance. Therefore, it is difficult to use it as a normal floor surface such as an indoor floor surface.

  Moreover, the structure of patent document 2 becomes a structure which attaches a surface fastener to a floor board and the base material of a floor board, and attaches a floor board to a base material with this surface fastener. Since it is a hook-and-loop fastener, only the specified floorboard can be easily removed, but on the other hand, it is a hook-and-loop fastener and there is a problem with the mounting strength. .

  Patent document 3 has been proposed by the applicant of the present application, but the floorboard has the same configuration as that of the conventional long floorboard, and the floor surface to be formed should have the same configuration as before. it can. Moreover, by removing the screws that attach each floor plate, the floor plate can be removed so that it can be reused. However, since the floor plate is sequentially removed to the floor under the floor to be opened, not only the floor board corresponding to the space under the floor to be opened is removed.

  In the inventions described in Patent Documents 4 and 5, each floor board (floor material) is arranged by male / female fitting, and the predetermined floor board is pulled up in the vertical direction and removed. However, these floorboard structures need to be formed in a substantially rectangular shape because of their structure, and the floor surface cannot be formed only by these floorboards (floor materials). That is, it is necessary to arrange the floor board (floor material) so as to stick to the base material as in the invention described in Patent Document 3, and therefore, there is a problem similar to that of the invention of Patent Document 3.

  The present invention is configured in view of the above-described problems of the prior art, and when a floor surface, a wall surface, and the like are formed, a plate material configured to retain the strength of the floor surface, the wall surface, and the like as such, and It is a surface structure using the same plate material, the plate material is composed of a plate material main body and a cover member, a recess is formed in the longitudinal (depth) direction of one side wall portion of both side wall portions of the plate material main body, On the other side wall portion, a plate material mounting portion is extended with respect to the width direction of the plate material main body, and on the side edge of the plate material mounting portion, a ridge is formed that engages with a recess of the adjacent plate material, and The cover member relates to a plate structure configured to be fixed to the plate member attaching portion by means such as fitting after the plate member is screwed to a predetermined target, and a surface structure in which the plate member is connected to form a floor surface or a wall surface. .

  Each plate can be easily attached to the object such as joists by attachment means such as screws, and the surface constructed as a floor surface or wall surface has sufficient strength by itself, and the plate material to be removed By removing the cover and exposing the plate material attaching portion, it is possible to easily remove the desired plate material by removing the attachment means such as screws, and to reuse the plate material.

  In addition, if this plate material is used, the floor portions, wall surfaces, and other surface portions that are formed can be formed in close contact with each other to form an integral surface. Compared to the shape-like surface or the like, the contact of the sole is comfortable, and dust and liquid do not enter from the gap. Further, even when configured as an outer wall, it can exhibit a sufficient function as an outer wall material without rain and wind entering.

  The plate material is made of metal such as aluminum so that the same shape can be mass-produced. A metal plate with a slightly complicated cross-sectional shape can be easily formed by using a metal, and a water cooling vessel is arranged at the lower part of the floor made of the same plate material to form a floor cooling / heating structure (the applicant of this application In the case of a large number of applications), an efficient floor cooling / heating structure can be obtained by forming the floor surface with a metal having a high heat transfer coefficient.

Embodiments of the present invention will be specifically described below with reference to the drawings.
First, the structure of the plate material according to the present invention will be mainly described with reference to FIG. The plate material is composed of a main body 1 and a cover member 2 fitted to the main body 1. First of all, the structure of the main body 1 will be described. The plate main body 1 is formed of a metal material such as aluminum by a method such as a drawing method. Although the figure shows the end face of the plate body 1, the plate body 1 is configured to have the same cross-sectional shape as the end face shape with respect to the depth direction in the figure. For example, the length (length in the depth direction in the figure) is It has a length of several tens of centimeters to several meters.

  A recess 3 is formed in one of the side wall portions 1a and 1b of the plate body 1 (side wall portion on the left side in the figure) 1a. On the other hand, from the lower end of the other side wall portion (right side wall portion in the figure) 1b, a plate material attaching portion 4 is formed so as to extend in the width direction of the plate material main body 1. In the plate material main body portion other than the plate material mounting portion 4, the upper surface portion 1c and the lower surface portion 1d are positioned with a certain vertical distance (corresponding to the thickness of the plate material). In the illustrated configuration, the upper surface portion 1c and the lower surface portion 1d of the plate body 1 are formed with space portions 6a, 6b, 6c via partition walls, but these space portions are not essential components of the present invention, It is formed to reduce the weight of the entire plate 1 and the metal used while maintaining a certain strength.

  Further, in the illustrated configuration, grooves are formed finely at substantially equal intervals along the length direction of the plate body 1 in the upper surface portion 1c. When the width of the plate body 1 including the width of the plate attachment portion 4 is about 7 to 8 cm, which is substantially the same as that of a conventional floor board, for example, the groove having a width of about 1.5 to 2 mm is the same groove. It is the structure arrange | positioned in parallel with the same space | interval as the width | variety of.

The formation of the groove in the upper surface portion 1c is not an essential component in the present invention, but it is effective to form the groove for the following reason.
First, when this plate material 1 is used as a floor board and a water container for cooling and heating is stored at the lower part of the floor surface, the surface portion 1c can have a large surface area. Therefore, in the floor cooling and heating structure, in the floor surface and under-floor space. The amount of heat transfer with the water container can be set large, and the efficiency of floor cooling and heating can be increased.

  In addition, since the metal material itself has almost no moisture absorption effect compared to wood, when it is used as a floor board, if it is a flat surface without a groove, the sole against the metal surface due to sweat or the like of the sole There is a possibility that the contact interval of the will deteriorate. In this case, if a fine groove is formed as described above, components such as sweat are released from the sole to the outside through the groove, so that the contact interval between the soles becomes very good.

  Next, a ridge 7 is continuously formed in the depth direction of the drawing at the side edge of the plate member mounting portion 4. Also, a pair of protrusions 5a and 5b are continuously formed in the depth direction in the figure on the bottom surface portion of the plate material mounting portion 4 which is extended from the lower surface portion 1d of the plate material main body 1 with a constant interval. By forming the pair of protrusions 5a and 5b, the screw can be easily positioned when the plate body 1 to be described later is screwed. Further, the plate material attaching portion 4 is formed in a single plate shape, and the entire plate material main body 1 is attached to an object such as a joist through this portion, so that the protrusions 5a and 5b are formed. If this is the case, this acts as a reinforcing material for the plate material attaching portion 4, and the strength of the entire plate material attaching portion 4 and further the attachment strength of the plate material main body 1 can be increased.

  Next, the configuration of the cover member 2 fitted to the plate body 1 will be described. The cover member 2 is composed of an upper surface portion 8A and a pair of leg portions 8B and 8C extending from the lower surface of the upper surface portion 8A. It is configured. In the upper surface portion 8A, grooves having the same size and shape as those formed on the upper surface portion 1c of the plate body 1 are formed at equal intervals, and when the cover member 2 is fitted and fixed to the plate body 1 as will be described later. The surface portion 1c of the plate body 1 and the surface portion 8A of the cover member 2 are configured to be integrated.

  The lower end portions of the leg portions 8A and 8B are formed with protruding portions 8b and 8c that protrude slightly outward, while engaging recesses 4a and 4b are formed on both side edges of the bottom of the plate member mounting portion 4. Accordingly, when the cover member 2 is pushed into the plate member mounting portion 4, the projections 8b and 8c of the leg portions 8B and 8C of the cover member 2 and the engagement recesses 4a and 4b are engaged, so that the cover member 2 is the plate member main body. 1 to be integrally attached.

Next, the attachment state and the removal state will be specifically described with reference to FIG.
First, a plate material that forms a side edge of a floor surface is arranged with respect to a reference surface such as an indoor wall surface. In the configuration shown in the figure, reference numeral 10 is a reference plane. The first plate member (indicated by reference numeral 1A) is disposed on the reference plane 10, and the plate member 1A is attached. In this case, the cover member 2 (2A) is removed as in the case of FIG. 1, and the plate member mounting portion 4 is exposed.

  In this state, the plate body 1 is attached to the attachment target (for example, joist) via the plate attachment portion 4 using the screw 11. In this case, if the plate main body 1 is made of aluminum, the screw 11 can be directly screwed into the object through the plate attachment portion 4, but an insertion hole is previously formed in the plate attachment portion with a drill or the like. In addition, the screw 11 may be screwed to the object through the insertion hole.

  When the fixing operation is completed, the cover member 2A is fitted and fixed to the plate material mounting portion 4 of the plate main body 1A that has been fixed. This operation can be carried out without using a special instrument by simply pushing the cover member 2A into the plate member attaching portion 4 by hand. By attaching the cover member 2A, the surface 1c of the plate member 1A and the surface 8A of the cover member 2A are integrated and fixed to the target as a single plate member having a certain width (for example, 7 cm as described above) including the plate member body 1A and the cover member 2A. Is done.

  Next, the adjacent plate 1B is attached by the same procedure as the plate 1A. In this case, in the figure, the right side edge of the plate body 1B is placed in contact with the left side edge of the plate body 1A so that the protrusion 7 of the plate body 1A has a recess in the plate body 1B with a certain margin space W. 3 is located. In this state, the plate body 1B is attached according to the above-described procedure, and by repeating this operation sequentially, predetermined plate bodies 1A, 1B, 1C, 1D,. Reference numerals 2B and 2C are cover members attached to the plate main bodies 1B and 1C, respectively, similar to those attached to the plate main body 1A.

Subsequently, the removal state of the plate material will be described with reference to FIGS. 3 to 5.
In the configuration of the present invention, any of the plate materials on which the floor surface is formed can be removed singly or continuously. Hereinafter, a case where the plate material 1B is removed will be described as an example.
First, the cover member 2B covering the plate material mounting portion 4 of the plate material main body 1B is removed. To remove the cover member 2B, for example, the cover member 1B is pry open using a screwdriver or the like at one end in the longitudinal direction of the cover member 2B. As described above, the cover member 1B has a special fixing member only by engaging the projections 8b and 8c of the leg portions 8B and 8C of the cover member 1B with the engagement recesses 4a and 4b of the plate member mounting portion 4. Since it is not used, if one end of the cover member 2B is lifted against this engaged state, the cover member 2B can be removed by hand without using a special instrument.

  In this way, the cover member 2B is removed, and each screw 11 is removed when the head of the screw 11 is exposed. If all the screws 11 are removed, as shown in FIG. 4, the plate body 1B is formed between the recess 3 of the adjacent plate body 1C and the protrusion 7 of the plate body 1B as shown by the arrow D1. The protrusion 7 is moved by the amount of the marginal space W which has been moved so as to contact the wall surface of the recess 3 of the plate body 1C.

  By the movement in the direction D1, the engagement state between the recess 3 of the plate body 1B and the protrusion 7 of the plate body 1A is released. In this state, as shown in FIG. 5, the plate body 1B can be removed from the floor surface by rotating the plate body 1B around the protrusion 7 in the direction of arrow D2 and then moving it up in the direction of arrow D3. it can. When the plate body 1C adjacent to the plate body 1B is also removed, the screw 11 is removed after removing the cover member 2C of the plate body 1C. In this case, since the adjacent plate main body 1B has already been removed, the plate main body 1C can be removed without being temporarily rotated in the D2 direction as shown in FIG. In this way, a desired plate body is removed.

  Next, when only the plate main body 1B is removed, the plate main body 1B is attached, and the removed plate main body 1B is inserted into the recess 3 of the adjacent plate main body 1C in the state shown in FIG. In this state, it is moved in the direction of D2 ′ around the ridge 7 and then moved in the direction of arrow D1 ′ shown in FIG. 4 to move the plate main body 1A and the plate main body 1B. The opposing side walls are brought into close contact, and in this state, the plate body 1B is fixed with the screws 11, and the cover member 2B is fitted into the plate attachment portion 4 to complete the operation.

  For example, when the plate material body 1B and the plate material body 1C are removed, the plate material body 1B is first arranged horizontally and moved in the direction D1 ′ in FIG. 4 to bring the plate material body 1A and the plate material body 1B into close contact with each other. Then, it is fixed with the screw 11 and the cover member 1B is inserted. Subsequently, with the plate main body 1B attached, the plate main body 1C completes the attachment in the same procedure as the moving member main body 1B attached.

FIG. 6 shows a second embodiment.
In this embodiment, the whole plate body can be lengthened by connecting the plate body shown in the first embodiment in the longitudinal direction.
Spaces 6a, 6b and 6c are formed in the plate body 1 as shown in FIG. Among these, for example, the connecting body 9 having the same outer diameter cross-sectional shape as the inner diameter cross-sectional shape of the spaces 6a and 6b is inserted from the rear end portion of the plate body 1 ′ to be connected and the front end portion of the plate body 1 ″ to be connected to both Link. Thereby, both board | plate material main bodies 1 'and 1''are integrated. Since the plate body 1 ′ and the plate body 1 ″ are individually fixed to the object by using the screws 11, the stress does not concentrate on the connecting portion even after the surface is formed. For this reason, it is sufficient to arrange the connection body 9 only in the space 6a of each plate material main body or in 6a and 6b. Incidentally, the cross-sectional shape of the space 6c is different from those of the other spaces 6a and 6b, and the connecting body 9 is also a special one adapted to this shape. Therefore, the space 6c is connected except when particularly necessary. It is not used as a structure.

  In the embodiment described above, the cover member 2 is attached to the plate body 1 by engaging the lower end of the leg portion of the cover member 2 with the recess of the plate member 4. In addition, the engagement between the leg portion and the recess is eliminated, and the plate member attachment portion 4 or the plate member attachment portion 4 is inserted from the upper surface portion of the cover member 2 at several locations in the longitudinal direction of the cover member 2. The screw may be configured to be screwed onto the plate body main body attachment target. In this case, the head of the screw for attaching the cover member is exposed on the upper surface portion 8A of the cover member 2. However, since the strength is not required except for the attachment of the cover member 2, for example, the cover member of several meters is 1 m Only a small number of screws can be used, such as tightening screws. In the case of screwing, the possibility of damaging the cover member is lower than in the case of prying open, so that the possibility of reuse of the cover member becomes even higher.

  The plate body is a part that secures the strength of these surface structures when the floor surface, wall surface, etc. are configured, but the cover member only covers the plate member mounting part of the plate body, and bears the strength in the surface structure. is not. For this reason, even if the plate body is made of a metal material having a certain strength, the cover member basically does not need to consider the strength. For example, a material with lower strength than the material constituting the plate body such as plastic is used. It is also possible to do.

  Although the case where the board | plate material in this invention was utilized as a floor board which forms a floor surface was demonstrated to the example, it is applicable also to the outer wall of structures, such as a house, or an indoor partition wall. If the surface is formed, the surface formation target need not be limited to a structure such as a house.

  Since the case where this board material is used as a floor board or exterior material of a house or the like has been described as an example, the size is 7 to 8 cm in width and the length is several tens of centimeters to several meters. Since it is possible from the beginning, it can be used for a wide range of purposes by forming it according to its use, such as the formation of floors and partition walls in factories where various heavy objects are arranged.

It is an end view of the board | plate material main body and cover member which concern on this invention. FIG. 2 is an end view of the floor surface in a state where the plate body and the cover member illustrated in FIG. 1 are connected to form a floor surface. It is an end view of the floor surface showing a first step of removing a predetermined plate material body.
