For the skeleton of wooden buildings, laminated lumber is often used in terms of strength and cost. There are various types of laminated lumber, and one of them is CLT. CLT is also called an orthogonal laminated board, and is made by laminating board materials called lamina. By making the grain direction of adjacent lamina orthogonal to each other, the directionality of strength is canceled and the thickness is appropriate. Therefore, it is possible to complete the skeleton of a building simply by connecting CLTs to each other. However, when connecting CLTs, a simple method such as driving a nail is often used, and there are problems in terms of labor, working time, and strength, and a simpler connecting method is desired. In addition, even with a simple connection method, it is necessary to ensure strength that can withstand use in the skeleton of a building.

Various hardware is often used to connect the members that make up a wooden building, as in the patent documents mentioned above. But there is a problem. Therefore, it is desirable that the hardware is not exposed on the surface of the member as much as possible. However, since the hardware is embedded, it is not preferable in terms of labor and working time if complicated processing is performed on the member. In particular, as in Patent Document 2 above, it is difficult to machine a long hole that penetrates both end faces of a pillar, and a means for avoiding this should be considered. In addition, deformation of wood due to moisture and dimensional errors during processing are unavoidable, and it is necessary to consider such errors.

The present invention has been developed based on such a situation, and can be used for connecting members such as CLT as an alternative to nails, it is easy to secure strength, and there is little exposure from the surface of the member, and the member. The purpose is to provide a connected structure that can be easily processed.

The invention according to claim 1 for solving the above-mentioned problems is a connecting structure used for integrating three or more integrated members, wherein the members include at least two wall materials and a lower portion thereof. It consists of a lower member located on the side, and has a plurality of hozos, a lower alignment shaft that has at least a male screw at the upper end and is fixed to the lower side of the lower member and protrudes upward, and a male screw at the upper and lower ends. A pair of upper and lower basic plates having an upper shaft, a nut screwed into the male screw, at least two through holes for penetrating the hozo, and a middle hole for penetrating the shaft, and contacting the wall material. A shaft groove in which the shaft is accommodated is formed in the center of the surface, hozo holes are formed in the upper and lower surfaces of the wall material and the upper surface of the lower member, and the lower basic plate is the lower surface. The male screw at the upper end and the male screw at the lower end of the upper shaft are connected with a nut while the shaft is passed through the middle hole, and the hozo is penetrated through the through hole and protruded from the basic plate. It is fitted into a hozo hole formed in the lower surface of an adjacent wall material and the upper surface of the lower member, and the basic plate is arranged so as to be in surface contact between the two wall materials and the lower member, and the upper side thereof. Two walls in a state where the pulling shaft of the nut is passed through the middle hole, the upper basic plate is placed on the upper surface of the two wall materials, and at least two of the hozo are passed through the through hole. It is fitted into a hozo hole formed on the upper surface of the material, the nut is screwed to the upper end of the shaft, and the basic plate presses the wall material and the lower member to press the wall material and the lower member. It is a connecting structure characterized by connecting members.

The connecting structure according to the present invention is used to collectively integrate three or more members that are accumulated in one place in various wooden structures such as wooden buildings, but the places of use are various, and more than one. There are various forms in which the members of the above are integrated. However, it is assumed that the surfaces of adjacent members are aligned in parallel and come into surface contact with each other. Further, the member is not limited to laminated lumber such as CLT, and general wood can be used, and either a bar or a plate may be used. In the present invention, two types of metal parts, a basic plate and a hozo, are used.

The basic plate is literally a flat metal plate, and only one sheet is used in one connecting structure, and it is sandwiched between the contact surfaces of adjacent members among the multiple members to be integrated, and all the members and surfaces to be further integrated. Arrange them so that they come into contact with each other. It should be noted that the surface contact is the front surface or the back surface of the basic plate, and it is assumed that only the side surface of the basic plate does not come into surface contact. Therefore, the shape and dimensions of the basic plate are determined according to the arrangement of the members to be integrated, and the basic plate may be rectangular or square. In addition, since the basic plate is embedded in the member, an embedded groove may be formed on the surface of some members as needed.

The hozo is a rod-shaped circular cross section protruding from the front surface or the back surface of the basic plate, and is fitted into the hozo hole processed into the member. In the present invention, it is premised that a plurality of rows of hozos having different axes are used for one basic plate, and the hozos may protrude only from one side of the basic plate, or the front and back sides may be penetrated through the basic plate. It may protrude from both sides. The hozo hole shall be machined in advance at a predetermined position. In addition, a fixing pin may be driven so as to penetrate the side peripheral surface of the hozo to integrate the hozo with the member.

In addition, the hozo protruding from either the front or back surface of the basic plate shall be fitted into the hozo holes of different members one by one. In the present invention, since the members accumulated in one place are in contact with each other, if one hozo is fitted into one member, it becomes impossible for the member to rotate around the hozo, and the member is displaced. Is regulated, and there is no need to increase the displacement any more. Further, by fitting only one hozo into one member, the number of hozos to be incorporated in one basic plate can be suppressed.

In this way, multiple rows of displacements are incorporated into one basic plate, the basic plates are arranged so as to be in surface contact with all the members integrated in one place, and the displacements protruding from the basic plate are each. By fitting it into a member, it is possible to collectively regulate a plurality of members so that they cannot be displaced through one basic plate, and the construction work is simplified.

In the invention according to claim 2, another lower member is provided, a shaft hole for penetrating the gathering shaft and the hozo hole are formed through, and the lower end of the other gathering shaft is screwed into the nut on the upper side, and the other The above-mentioned connecting structure having the above-mentioned configuration is obtained by penetrating the shaft hole of the lower member, fitting the hozo into the hozo hole, and screwing the other gathering shaft into the nut on the upper side. As an alternative to the upper shaft and the lower shaft connected by the nut, the structure of the connecting structure having the above configuration is further added. The hozo can be integrated with the basic plate by welding, press fitting, or the like, but as in the present invention, the hozo can be displaced in the axial direction without being integrated with the basic plate.

In order to insert the hozo, a through hole is provided in the basic plate in advance. However, the work of integrating the hozo and the basic plate is not performed. Therefore, the hozo can be displaced even after construction, but in order to prevent the hozo from coming off the through hole, the depth of the hozo hole is adjusted to limit the displacement range of the hozo. The through hole has an inner diameter with a margin for the hozo. As a result, various dimensional errors are absorbed, and the hozo can be easily fitted into the hozo hole.

In the invention according to claim 3, the wall material is composed of three members, a central wall material is sandwiched between the left and right wall materials, and the wall material is arranged in a clove shape in a plan view and connected by the nut. Two sets of the lower alignment shaft and the upper alignment shaft are provided, the hozo holes are provided on the upper and lower surfaces of the left and right wall materials and the center wall material, and the through holes are provided in the basic plate. It is characterized in that three holes are provided corresponding to the clove holes and two middle holes are provided between the through holes to penetrate the gathering shaft. Two basic plates are arranged so as to sandwich a specific member. Therefore, the hozo is not incorporated into each basic plate by itself, but is lengthened and arranged so as to penetrate the two basic plates.

In the present invention, it is impossible to integrate the hozo and the basic plate in consideration of the construction procedure. The basic plate is provided with a through hole for inserting the hozo, and the basic plate and the hozo are sequentially inserted at the time of construction. I will incorporate it. In the present invention, it is assumed that the basic plates are arranged on the front surface and the back surface of the plate-shaped member, and the hozo penetrates between them, and the hozo holes do not become long. By arranging the hozos so as to penetrate the two basic plates in this way, the number of hozos can be reduced and the manufacturing cost of parts can be suppressed. Moreover, some of the hozo holes can be penetrated without having a bottom, which simplifies the processing of the hozo holes and reduces the labor during sawing.

The invention according to claim 4 is characterized in that the hozo can be displaced along the axial direction of the through hole of the basic plate. The invention according to claim 5 is characterized in that the member is an orthogonal laminated lumber or other laminated lumber.

In this invention, in addition to the conventional basic plate and hozo, a shaft and a nut are used. Among them, the shaft is an elongated metal rod such as an anchor bolt or a full screw bolt, and a male screw is formed at the end thereof. It is something that is. It is assumed that one end of the shaft is connected to a heavy object such as foundation concrete that can receive a tensile load. In addition, the basic plate is provided with a middle hole for passing the gathering shaft, and when only the male screw at the end of the gathering shaft protrudes from this middle hole and a nut is screwed into it and tightened, the basic plate becomes the foundation. It is attracted to concrete or the like and can press the member.

The alignment shaft cannot be arranged freely and is embedded inside the member. Therefore, the member is machined with a shaft hole and a shaft groove for passing the shaft. If the shaft penetrates the front and back surfaces of the plate-shaped member, a shaft hole is machined in the member, but the extension of the shaft hole is the same as the plate thickness and can be machined without difficulty. Further, when the alignment shaft is arranged along the end face of the member, a shaft groove is formed in the end surface of the member, and the alignment shaft is accommodated therein. Therefore, it is not necessary to drill a long hole that penetrates both end faces of the member. Since the entire shaft groove is exposed to the outside, it can be easily machined with a tool such as a router.

In this way, in addition to the basic plate and hozo, by using the shaft and nut, the displacement of the member is regulated by the hozo, and by screwing the nut to the shaft, the member is connected via the basic plate. Can be pressed. Therefore, a compressive load acts on the member, and the member can be installed on the foundation concrete or the like without loosening. Moreover, since the shaft and the nut are housed in the shaft hole and the shaft groove processed in the member, they are not exposed to the outside.

A basic plate and a displacement are used as a connecting structure that integrates three or more members that are integrated in one place, and multiple rows of displacements are incorporated into one basic plate, and the basic plate is sandwiched between the contact surfaces of the members. Moreover, the basic plate is arranged so as to be in surface contact with all the members to be integrated, and further, by fitting the displacement protruding from the basic plate into each member, a plurality of members are collectively put together via one basic plate. Therefore, it can be regulated so that it cannot be displaced, and the construction work is simplified as compared with the conventional method such as driving nails.

In addition, the fit between the hozo and the hozo hole ensures that the load acting in the radial direction of the hozo is received and has excellent strength, so it can be used without problems even when constructing the skeleton of a building. can. In addition, the basic plate can be easily embedded in the contact surface between adjacent members, and no metal parts are exposed around the connecting structure, so that the basic plate is also excellent in terms of aesthetics. In addition, the grooves and holes for embedding the basic plate and hozo can be machined with a general-purpose tool, which does not increase the cost.

The basic plate is provided with a through hole for inserting the hozo, and the hozo can be displaced along the axial direction of the through hole, so that a gap can be secured at the boundary between the basic plate and the hozo, and the member can be used. It will be possible to absorb the dimensional error of the machined hozo hole. Therefore, the fitting work of the hozo can be smoothly performed, the workability is improved, and the time is shortened. In addition, the time to insert the hozo can be freely decided, increasing the flexibility of the construction procedure.

By arranging two basic plates so as to sandwich a specific member, and arranging the hozo so as to penetrate the two basic plates, the number of hozo can be reduced and the manufacturing cost of parts can be suppressed. can. In addition, some hozo holes can be penetrated without having a bottom, which simplifies the processing of hozo holes and reduces the labor required for sawing.

In addition to the basic plate and hozo, by using a shaft and nut, the displacement of the member can be regulated by the hozo, and by screwing the nut to the shaft, the member can be pressed through the basic plate. can. Therefore, a compressive load acts on the member, and the member can be installed on the foundation concrete or the like without loosening.

Since the shaft and nut are housed in the shaft hole and shaft groove processed into the member, they are not exposed to the outside and do not deteriorate the aesthetic appearance. In addition, the shaft groove can be easily machined with a tool such as a router, and the increase in labor and cost can be suppressed. Furthermore, at the time of construction, the work is completed only by embedding the basic plate, fitting the hozo, and tightening the nut, so it takes less time and effort than the conventional simple nailing.
