Description

Connection structure, decoration method, and connection structure assembly Technical Field The present invention relates to a connection structure, a decoration method using the connection structure, and a connection structure assembly. Background Conventionally, as building materials such as wall materials, interior materials, floor materials, and ceiling materials, it has been known to use functional building structures. Such a structure includes, for example, a base material serving as a support and a functional layer laminated on the base material (for example, patent document 1). The functional layer is provided with various functions according to the purpose or purpose. In such a structure, the functional layer and the base material are fixed using an adhesive. In addition, not only the structure for construction but also an adhesive is generally used for fixing two structures. Prior art literature Patent literature Patent document 1 Japanese patent laid-open No. 2020-062775 Disclosure of Invention Problems to be solved by the invention However, in the case of manufacturing a structure in which two structures are fixed by an adhesive, it is difficult to fix the two structures with high accuracy. Therefore, the step of fixing the two structures with an adhesive is difficult to automate. In addition, even if this process can be automated, the cost increases. Further, once the two structures are fixed with an adhesive, it is difficult to correct them later, and it is also difficult to separate the two structures. For example, in a structure in which a base material and a functional layer are fixed with an adhesive, it is difficult to remove the functional layer from the base material. Further, since the adhesive is often made of a resin material derived from petroleum, the operation itself of fixing using the adhesive is an operation that places a burden on the environment. In addition, in a structure in which a base material and a functional layer are bonded, even if the functional layer can be removed from the base material, an unnecessary adhesive is often attached to the functional layer, and the removed functional layer is not easily recycled or recovered. In this case, when the adhesive layer to which the adhesive is attached is removed and incinerated, carbon dioxide gas is exhausted in relation to the greenhouse effect. In this way, the method of fixing two structures by an adhesive has a problem of high environmental load. Therefore, a technique of detachably connecting two structures has been studied. For example, in a structure having a base material and a functional layer, a case in which the base material and the functional layer are detachably fitted and connected has been studied. In this case, as the fitting portion, it is conceivable to provide a convex portion on one of the base material and the functional layer and a concave portion on the other of the base material and the functional layer, to connect the base material and the functional layer by fitting the convex portion and the concave portion, or to separate the base material and the functional layer by removing the fitted convex portion and concave portion. However, in a conventional connecting structure in which two structures are detachably connected by fitting the protruding portion and the recessed portion into each other, the attaching/detaching performance (ease of fitting and easiness of removal) and the holding performance in the connected state are opposite, and are in a trade-off relationship, so it is difficult to achieve both the attaching/detaching performance and the holding performance in the connected state. For example, when the attaching/detaching performance is improved so that the protruding portion and the recessed portion can be easily fitted or removed, the holding performance of the coupled state is lowered, and the coupled two structures are easily detached. That is, after the two structures are connected, the two structures may be detached although the two structures are not intended to be detached. On the other hand, when the holding performance of the coupled state is improved, the convex portion and the concave portion are difficult to fit into or remove from each other, and the attaching/detaching performance is lowered. The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a connection structure having two detachable structures each having an insertion portion, and capable of achieving both of the detachable performance and the holding performance in a connected state, and a decoration method using the connection structure. Means for solving the problems A connection structure according to one embodiment of the present invention includes a1 st structure and a2 nd structure detachably connected to the 1 st structure, wherein the 1 st structure includes a1 st embedded portion, the 2 nd structure includes a2 nd embedded portion d
