Abstract

(57) [Abstract] [Purpose] When constructing a wall surface from a fiber reinforced cement wallboard, the purpose is to eliminate the discomfort in the joints and improve the appearance. [Structure] In a joint structure of wall plates in which wall plates 1A and 1B are connected through a joint step while forming joints, thin wall parts 4A and 4B for forming joints are wall plates 1A and 1B. Is formed at both end portions to be joined of the thin wall portions 4A and 4B, and the connection portions are provided at the joint portions 2 so as to be inconspicuous. To do.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to improvement of a joint structure of wall plates.

[0002]

[Prior art]

 Conventionally, the outer wall of a building is constructed by sequentially joining wall boards made of inorganic cement, which are molded in advance to a unit size. This method of sticking wallboards does not require a curing period compared to the wall surface construction method of painting specifications and the wall surface construction method of casting specifications with molds, and there is no need for additional equipment such as scaffolds and templates during construction. It is not necessary and has the advantage that a wall with any decoration can be constructed easily.

[0003]

[Problems of conventional technology]

 However, when the wall surface was made of inorganic cement wallboard, there was a problem that joints between wallboards were conspicuous. For example, in the case of wall boards A, A, etc. with a pattern of brick joint, etc., as shown in FIG. 3, so that the connecting portion exactly coincides with the joint portion C, mutual joints of the wall boards A, A are joined together. B and B are formed, and the connecting portion D is connected so as to be in the same state as other joints. Usually, since this joint portion is often provided by a cutting process after curing the wall plate, Due to the difference in surface condition, this portion D is conspicuous and there is a drawback that it feels uncomfortable with other joints C.

[0004]

[Problems to be solved by the device]

 In view of the above problems, the present invention is intended to eliminate the discomfort of joints and to obtain a wall board joint structure having an excellent appearance when constructing a wall surface from a fiber reinforced cement wall board. is there.

[0005]

[Means for Solving the Problems] That is, in the wall plate joint structure of the present invention, the wall plates 1A and 1B are connected to each other through a joint step so that the joint 2 is formed. In the joint structure, thin-walled portions 4A and 4B for forming joints 2 are provided at both end portions of the wall plates 1A and 1B to be joined, and a mating step portion is fitted to the thin-walled portions 4A and 4B. 3A and 3B are formed and connected.

[0006]

【Example】

 Next, an embodiment of this invention will be described. 1 is a sectional view of an embodiment of the present invention, and FIG. 2 is a perspective view of the embodiment.

The joint structure of wall plates according to the present invention is a joint structure of wall plates 1A and 1B in which wall plates 1A and 1B are connected via a joint step so that joints 2 are formed. The thin wall portions 4A and 4B for forming 2 are provided at both end portions of the wall plates 1A and 1B, and the thin wall portions 4A and 4B are formed with the hollow step portions 3A and 3B which are fitted to each other. Are connected and configured. In addition, reference numeral 5 in the drawing denotes a sealing material which is inserted as necessary.

In the above-described embodiment, if the stripe-shaped concavo-convex pattern 4C is formed in the thin portions 4A and 4B, the joint 2 cannot be distinguished at all.

[0009]

[Action]

 In the wall plate joint structure of the present invention, since the joint portion of the wall plates 1A and 1B is the bottom surface of the joint 2, the joint line is confused with the joint and cannot be distinguished. In particular, if a stripe-shaped concave-convex pattern 4C is formed on the bottom surface of the joint, it becomes impossible to distinguish them at all.

[0010]

[Effect of device]

 As described above, in this invention, since the joint step is arranged at the joint bottom portion in the jointing step portion of the wallboard, the joint becomes inconspicuous, and moreover, the joint portion is the wallboard manufacturing process. Since it can be molded with a press or the like, it is indistinguishable from other decorative joints, and even if the gouging step is cut and finished, that part will be hidden from the surface of the wallboard, so the appearance of the joint will be different. It is possible to form a joint that does not feel any discomfort compared to the portion.
