Description

  The present invention relates to a joint member for cross tension that performs joint finishing between wall boards or joint finishing of an end portion of a wall board in construction for performing cross tension on a wall surface in a room.

  Conventionally, interior finishing has been performed in which a wall surface is formed by attaching a wall surface board such as a plaster board to a base material of the wall surface, and a cloth material is attached to the wall surface. In such interior finishing construction, there is a construction method in which a cloth material is attached to the entire wall surface without forming joints on the wall surface, but in this construction method, the wall surface with the cloth material looks vaguely appearance. , There was a drawback of giving the room a tight impression.

  Therefore, conventionally, a construction method is provided in which a separation portion is provided between wall surface boards such as a plaster board and a joint is formed by folding the end portion of the cloth material adhered to the surface of the wall surface board into the separation portion between the wall surface boards. Is adopted.

  However, in such construction methods, the plaster board, which is generally adopted as a fire-resistant wall board, has a structure in which a paper material is attached to both sides of a gypsum board, so that the corners are weak and easy to chip. There was a problem. For this reason, various construction methods have been conventionally employed in order to eliminate the disadvantages of such plaster boards.

  For example, in the conventional construction method shown in FIG. 7A, a wooden frame member 22 is fixed to an end portion of a wall surface board 21 such as a plaster board fixed to the base material 20 of the wall surface, and the adjacent wooden frame materials 22 and 22 are provided. A joint space is formed by providing a spacing portion 23 therebetween. Next, a cloth member 24 is attached to the upper surface of the wall board 21, and an end portion of the cloth member 24 is folded into a space 23 between the wooden frame members 22 and 22.

  According to such a configuration, the tightness between the wall board 21 and the wooden frame member 22 is maintained at the beginning of construction, but when the wooden frame member 22 contracts during drying, as shown in FIG. There is a problem that a gap 25 is formed between the wall board 21 and the wooden frame member 22 and a dent 26 is formed in the cloth member 24 stretched on the upper surface of the gap 25, so that the appearance of the cloth member 24 is deteriorated. .

  Further, as shown in FIG. 7A, when the wooden frame member 22 expands or due to some impact or the like, the corner portion of the wall surface board 21 is damaged, and the cloth member 24 stretched on the upper surface of the damaged portion 27. There was a problem that deformation occurred.

  In order to solve such a problem, a joint member conventionally called a “hat joint” has been used. As shown in FIG. 8, the joint member 28 has flat sleeve portions 30, 30 formed on both sides of the concave section 29. The joint member 28 is separated from the wall boards 21, 21 by a separation portion 31. The corners of the wall surface board 21 such as a plaster board are protected by being attached later.

  However, in this joint member 28, since the sleeve portions 30, 30 provided on both sides of the concave section 29 are placed on the upper surfaces of the wall surface boards 21, 21 on both sides of the spacing portion 31, the thickness of the sleeve portion 30 is increased. This is the situation that protrudes to the indoor side. Accordingly, when the cloth member 24 is attached to the upper surface of the wall surface board 21 provided with the sleeve portion 30 in this way, the cloth member 24 appears to rise up by the thickness of the sleeve portion 30 protruding to the indoor side. The result will be poor.

  Therefore, as a conventional technique for solving such a drawback, there is “bottom joint structure of interior wall surface” described in Patent Document 1. In the configuration of this document, a bottom joint member having a concave groove formed in the center is provided as a joint portion, and a protrusion is provided at the opening edge of the bottom joint member, and a flat surface formed on the outer side of the protrusion. A sheet is affixed.

  Therefore, this document 1 has a structure in which the end portion of the sheet extends along the protrusion of the bottom joint member, and the end portion of the sheet is separated from the joint member as in the structure shown in FIG. It is not a structure that can be folded in.

  Further, the bottom joint member of Patent Document 1 is formed such that the upper surface of the wall panel provided on both sides of the member is flush with the flat surface of the bottom joint member. In addition, an inclined surface is formed on both sides of the flat surface of the bottom joint member, and a putty reservoir having a V-shaped cross section is formed by a configuration in which chamfering is also performed on the end portion of the wall panel. With such a configuration, when the putty reservoir is filled with putty, the flat surface of the bottom joint member and the upper surface of the wall panel are flattened, and the flatness of the sheet adhered thereon can be maintained.

  However, in the above configuration, it is necessary to chamfer the end portion of the wall panel, which not only requires labor, but in the case of a plaster board, the corner portion of the plaster board The inconvenience of becoming fragile and easily missing occurs.

It is sectional drawing which shows the structure which provided the hat joint in the separation part of the conventional joint part.

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

  As shown in FIG. 2 (c), the cross-sealing joint member 1 of the present embodiment is provided with a wall base board 2 such as a plaster board provided on a wall base material 2 provided along the wall of the building. This is a joint member for attaching the cloth material 4 to the surface of the center joint member 1A, which is provided in the space between the adjacent wall boards 3 and 3 and provided at the center joint member 1A.

  When this joint member is described in detail, the center joint member 1A of the present embodiment is a long member having a rectangular cross section made of a synthetic material having no shrinkage, and the length of this member depends on the construction situation. It is arbitrary. In addition, as a non-shrinkable synthetic material constituting the center joint member 1A, a slurry obtained by adding glass fiber and SBR latex to zonotlite, which is a crystal of calcium silicate, is pressure-molded and dried. Artificial wood is preferably used, and “ACELITE” (trade name) is known as a commercial product.

  In addition, this artificial wood, in particular “ACELITE” (trade name), is known as a material having no elasticity such as ± 0% when heated at 160 ° C. due to water absorption or heat. It has various advantages as a building material that replaces wood.

  To further describe other advantages of this artificial wood, it has heat resistance and fire resistance up to 1000 degrees Celsius. Further, this artificial wood has no dimensional change with respect to water absorption, moisture absorption, heating, etc., and is excellent in aged weather resistance. In addition, it is not toxic, is not affected by alterations and insect damage, has good workability, has excellent holding power for fixing members such as nails and screws, and is lightweight and has excellent workability. .

  As the shape of the center joint member 1A of the present embodiment, as shown in FIG. 1 (a) or (b), it is a long member having a rectangular cross section, and the longitudinal direction of the center of the front side plane 5 facing the room A joint groove 6 is formed along the surface, and chamfers 7 are formed along both ends of the front side plane 5 on which the joint groove 6 is formed. Further, the depth width (D3 = 11 mm) of both side surfaces of the member obtained by subtracting the height of each chamfer 7 is formed to be the same as the thickness (D4 = 11 mm) of the wall surface board 3 (FIG. 2A). )reference).

  As an example of specific dimensions of the center joint member 1A of the present embodiment, as shown in FIG. 1B, the center joint member 1A has a lateral width W1 of 50 mm, a center joint member 1A has a thickness D1 of 13 mm, and a joint groove. 6 has a width W2 of 3 mm, a groove depth D2 of the joint groove 6 is 8 mm, a chamfer 7 has a surface side width d1 of 2 mm, and a chamfer 7 has a side surface width d2 of 2 mm.

  In order to attach such a center joint member 1A to the wall base material 2, the center joint member 1A of the present embodiment is attached to the surface of the wall base material 2 as shown in FIGS. 2 (a) to 2 (c). , Fix with cucumbers, screws, etc. In such a configuration, by using a plaster board for both the wall base material 2 and the wall surface board 3, a double wall made of a plaster board having excellent fire resistance is formed.

  In addition, as a method for fixing the center joint member 1A, it is possible to improve work efficiency by using an air nail called “finish nailer”.

  When the wall surface of the room is formed by using the center joint member 1A, the thickness D4 of the wall surface board 3 such as a plaster board subtracts the height d3 of the chamfer 7 as shown in FIGS. It becomes the depth width D3 of the side surface 11 of the center joint member 1A. Therefore, when the back surface of the center joint member 1A and the back surface of the wall surface board 3 are fixed to the surface of the wall base material 2, the chamfer 7 is inclined to extend the surface of the wall surface board 3, as shown in FIG. Formed into a state.

  Then, as shown in FIG. 2B, the putty 12 is applied from the chamfered portion 7 of the center joint member 1A and smoothed along the upper surface of the wall surface board 3 so as to form a smooth inclination. As shown in (c), the end portion of the cloth material 4 adhered to the surface of the wall board 3 is folded into the joint groove 6. As a result, the folding portions 4a and 4a of the cross member 4 are folded into both sides of the joint groove 6 in a clean state by forming two straight lines having the same width at both corner portions.

  In addition, when the chamfer 7 is not formed in the corner portion of the center joint member 1A and the upper surface of the center joint member 1A and the upper surface of the wall surface board 3 are the same surface, the corner portion of the wall surface board 3 such as a plaster board has some impact or the like. Depending on the case, it becomes easy to chip.

  For this reason, in the present embodiment, the chamfer 7 is formed at the corner of the center joint member 1A as described above, and the putty 12 is applied from the inclined surface of the chamfer 7 to smoothly incline along the upper surface of the wall board 3. Then, the cloth material 4 is adhered to the surface of the wall board 3 after leveling. With such a configuration, the putty 12a covered with the inclined surface of the chamfer 7 of the center joint member 1A becomes familiar with the lower surface of the cloth member 4, so that the upper surface of the boundary between the center joint member 1A and the wall board 3 is a uniform surface. Thus, the cloth material 4 can be uniformly adhered to the upper surface thereof.

  In addition, about the construction method which positions the upper end of the center joint member 1A of a present Example with respect to a ceiling surface, it will mention later with the construction method of the end joint member 1B of Example 2. FIG.

  As shown in FIG. 4 (c), the cross-sealing joint member 1 of the present embodiment is provided with a wall surface board 3 such as a plaster board on a wall base material 2 provided along the wall surface of the building. It is related with the end joint member 1B at the time of sticking the cloth material 4 on the surface.

  The end joint member 1B will be described in detail. As a material to be used, like the center joint member 1A of the first embodiment, a long member having a rectangular cross section is formed of a synthetic material having no contractibility. As the synthetic material having no shrinkage, like the center joint member 1A of Example 1, an artificial material manufactured by press-molding and drying a slurry containing zonotlite as a main component and adding glass fiber and SBR latex is dried. Commercially available “ACELITE” (trade name) may be used as the wood.

  Further, as shown in FIG. 3A or 3B, the end joint member 1B of the present embodiment is a long member having a rectangular cross section, and a joint step 8 is formed on one side thereof. In addition, a chamfer 7 is formed along the other front corner. Further, the depth width (D8 = 11 mm) of the side surface 11 of the member obtained by subtracting the height d4 of the chamfer 7 is formed to be the same as the thickness (D4 = 11 mm) of the wall surface board 3 (FIG. 4A). )reference).

  As a specific dimension example of the end joint member 1B of this embodiment, as shown in FIG. 3B, the height H1 of the end joint member 1B is 25 mm, and the thickness D5 of the end joint member 1B is 13 mm, groove depth D6 of joint step 8 is 8 mm, width D7 of joint step 8 is 2 mm, surface side width d3 of chamfer 7 of end joint member 1B is 2 mm, and side surface width d4 of chamfer 7 is 2 mm. It is.

  In the case where the end portion of the indoor wall surface on the ceiling surface side or the like is formed using the end joint member 1B having such a shape, the thickness of the wall surface board 3 such as a plaster board as shown in FIGS. The length D4 is the same as the depth width D8 of the side surface 11 of the member obtained by subtracting the height d4 of the chamfer 7.

  Therefore, also in the present embodiment, as in the first embodiment, the chamfer 7 is left in an inclined state for extending the surface of the wall board 3. Therefore, the putty 12 is applied from the chamfered portion 7 of the end joint member 1B, leveled so as to form a smooth slope along the upper surface of the wall board 3, and the cloth material 4 adhered to the surface of the wall board 3 When the end portion of the cross member 4 is folded into the step difference step 8, the folded portion 4a of the cross member 4 is folded in a state of forming a clean straight line at the corner portion.

  In the present embodiment, as in the first embodiment, the chamfered portion 7 is left in an inclined state to extend the surface of the wall board 3. Therefore, the putty 12 is applied from the chamfered portion 7 of the end joint member 1B, leveled so as to form a smooth slope along the upper surface of the wall board 3, and the cloth material 4 adhered to the surface of the wall board 3 When the end portion of the cross member 4 is folded into the step difference step 8, the folded portion 4a of the cross member 4 is folded in a state of forming a clean straight line at the corner portion.

  With this configuration, the putty 12a covering the inclined surface of the chamfer 7 of the end joint member 1B conforms to the lower surface of the cross member 4 in the same manner as in the first embodiment, and therefore the boundary between the end joint member 1B and the wall board 3 It becomes possible to make the upper surface of the uniform surface uniform and to adhere the cloth material 4 uniformly to the upper surface.

  Here, the installation construction of the center joint member 1A and the end joint member 1B will be described with reference to FIGS.
