Abstract

[PROBLEMS] To solve the problem of the present invention is that, even when a base member is displaced in a two-dimensional direction and in a slight vertical direction, the force accompanying the displacement does not overload the house body, and the house body can be stably moved. It is an object of the present invention to provide a fixture that can be supported and an attachment structure that allows movement between members using the fixture.
A mounting structure that allows movement between members according to the present invention is a strip-like shape in which one screw of a rod-like member threaded at both ends is fixed to a base member. There are mounting holes in the vicinity of both end portions, and a U-shaped member is integrated with the same width dimension as the strip-shaped member in the central portion of the strip-shaped member, and a long-hole-shaped groove portion is integrated. A stopper member is screwed into the other side threaded portion, and the other member is fixed to the mounting hole of the fixing bracket via a fixture.

Description

  The present invention relates to a fixing bracket that allows movement between members, particularly a fixing bracket that is suitable for fixing a tree house in which relative displacement occurs between fixing portions, and a mounting structure using the same.

  A tree house is a structure built on the basis of a living tree. In general, many are built on trees. There are people who live in tree houses overseas, and there are hotels in tree houses, but they are not accepted as buildings in Japan, so they cannot be made houses. However, when you spend time on a tree feeling the wind together with the tree, listening to the rustling sounds of the leaves, smelling the scent of the tree, and spending time, humans are essentially part of nature. I can feel it. You can see the extraordinary world from a different point of view, and be immersed in a sense of openness to recover humans. Due to the charm of such a tree house, the demand for a tree house (see the photo in FIG. 5) has recently increased as a space for camping and hobbies.

  Treehouses are buildings based on trees, so they have special circumstances that are different from moving foundations that cannot remain stationary when the wind blows, and earthquakes that cause relative displacement between two or more foundations at random. Yes. In short, it can be said that the building foundation has extremely unique circumstances. For example, when a tree house is constructed in a place where trees are branched into three, if the wind blows, the three branches that are the foundations will oscillate asynchronously in different directions. If the foundations are in the same branch, the relative displacement is small, but a large relative displacement occurs between the foundations of the other two branches. When a plurality of foundation members are individually firmly fixed to a tree and fixedly connected to the house structure, the displacement force between the branches is directly applied to the house body as a load. Such a phenomenon shortens the life of the house and causes serious problems that threaten the safety of the house after the years.

  The fixing bracket of the present invention employs a mechanism that forms a long hole groove as will be described later, and absorbs the displacement between the members by a clearance with a rod-like member fixed to the foundation fitted in the long hole groove. . Then, when the prior art was investigated about such a mechanism, patent documents 1 and 2 were discovered. The “elevator sill device” of Patent Document 1 is designed to easily attach the mounting bracket horizontally and easily position the sill without being affected by the unevenness of the horizontal part of the building frame constituting the landing. The purpose is to fix the vertical base of the mounting bracket so that it can be moved in the vertical and longitudinal directions using anchor bolts in the vertical part of the building frame, and to be moved up and down using jack bolts on the horizontal part of the mounting bracket. A beam is attached and a horizontally long hole is provided in the vertical attachment portion of the mounting bracket, and the receiving beam is attached so as to be movable in the left and right direction by a bolt penetrating the horizontally long hole. The technical significance of this configuration is not to allow relative displacement during use, which is intended by the present invention, but to allow positional displacement during installation. It is.

Patent Document 2 “Self-weight receiving bracket for mounting an outer wall panel, mounting bracket and structure” is intended to provide a mounting bracket for an outer wall panel that allows easy panel mounting and high panel mounting strength. The bracket is integrally formed with a horizontal portion and a vertical portion having a first flat portion, a second flat portion, and a third flat portion that are orthogonal to the horizontal portion and are connected in order from the horizontal portion. In use, the first flat part and the third flat part protrude below the horizontal part, and the third flat part has a long through hole in the width direction, and the support fitting slides in the through hole. A possible configuration is disclosed. This mounting bracket and structure have an effect that the outer wall panel can be prevented from being damaged due to rocking such as an earthquake by sliding the bolt and the support bracket within the through-hole of the weight holder. This invention is similar to the present invention in that it is a mechanism that allows relative displacement after mounting, but this bracket is a one-dimensional displacement allowance mechanism, and a plurality of foundations such as tree houses are randomly relative to each other. It cannot cope with special circumstances that are different from earthquakes such as two-dimensional displacement and slight vertical displacement.

  The problem of the present invention is to support the house body stably without overloading the house body even if the displacement between the base members is a two-dimensional displacement and a slight vertical displacement. It is another object of the present invention to provide a fixing bracket that can be used, and to provide an attachment structure that allows movement between members.

The fixing bracket that allows movement between the members of the present invention has a strip shape, mounting holes are formed in the vicinity of both ends thereof, and a U-shaped member is formed in the center of the strip shape. It was integrated with the same width as that of the member, and a long hole-shaped groove portion was integrally provided.
The mounting structure that allows movement between members of the present invention is such that one rod of a rod-like member threaded on both ends is fixed to the base member, and the rod-like member is passed through the groove portion of the fixing bracket. The stopper member is screwed onto the other side screw portion, and the other member is fixed to the mounting hole of the fixing bracket via a mounting tool.
Further, in the mounting structure that allows movement between the members of the present invention, the distance between the member surface on which one screw is fixed and the mounting position of the stopper member is larger than the thickness dimension of the fixing bracket.
Furthermore, the mounting structure that allows movement between members of the present invention is such that the diameter of the rod-shaped member is smaller than the width dimension of the groove portion of the fixture.

  The fixing bracket of the present invention has a strip shape and has mounting holes in the vicinity of both ends thereof, and a U-shaped member is integrated with the same width dimension as the strip member at the center of the strip shape. Since the long hole-shaped groove portion is engaged with the rod-shaped member fixed to the other member, the members can be coupled while allowing displacement in the longitudinal direction.

The mounting structure that allows movement between members of the present invention is such that one rod of a rod-like member threaded on both ends is fixed to the base member, and the rod-like member is passed through the groove portion of the fixing bracket. Since the stopper member is screwed to the other side screw portion and the other member is fixed to the mounting hole of the fixing bracket via the fixture, the engagement between the fixing bracket and the rod-shaped member is A large relative displacement is allowed in the longitudinal direction of the long hole groove, and this allows a relative displacement between the base member and the other member. Therefore, there is no possibility that both members are subjected to an excessive load to expend wear.
In addition, the mounting structure that allows movement between the members of the present invention is such that the distance between the member surface on which one screw is fixed and the mounting position of the stopper member is larger than the thickness dimension of the fixing bracket. As for the displacement in the direction orthogonal to the longitudinal direction of the part, the displacement corresponding to the clearance can be allowed. There is a synergistic effect that the displacement with respect to the two-dimensional relative displacement can be allowed in cooperation with the degree of freedom in the longitudinal direction of the groove.
Furthermore, in the mounting structure that allows movement between members of the present invention, the diameter of the rod-shaped member is smaller than the width dimension of the groove portion of the fixing bracket, so that the displacement in the width direction can be permitted by the clearance. . There is a synergistic effect that the three-dimensional relative displacement can be allowed in cooperation with the above-described degree of freedom with respect to the two-dimensional relative displacement.

  The fixing bracket of the present invention will be described with reference to FIG. In FIG. 1, reference numeral 1 denotes a fixing metal fitting, 1a is a strip-shaped member, and a U-shaped member is integrally coupled to a central portion of one side surface of the strip-shaped member 1a. In the example of this figure, two members are shown integrated by welding, but may be integrally formed as a cast product from the beginning. The strip-shaped member 1a and the U-shaped member 1b are integrated with the same width dimension, and a groove portion having a long hole shape is formed by these two members. Attachment holes 1c are formed in the vicinity of both ends of the strip-like member 1a, and are formed so that they can be fixed to a structure of a tree house such as a beam with a fixture such as a bolt.

  The fixing bracket 1 is coupled to a base portion (tree body) by a rod-like member 2 as shown in FIG. 2 and a stopper member 3 such as a nut. Screw grooves 2a and 2b are cut on both sides of the rod-like member 2, and the central portion 2c is in the form of a round bar. The stopper member 3 is a nut-shaped metal member, and has a female screw 3a screwed into the screw groove 2a of the rod-shaped member at the center. Further, in the example shown here, the stopper member 3 is formed with a small-diameter screw hole 3b in the radial direction, and a pin screw 4 is screwed into the screw hole 3b so that the tip portion thereof can contact the rod-like member 2. It is like that. As shown in the upper part of FIG. 2, the stopper member 3 is screwed to the central portion 2 c in the long screw portion 2 a and the pin screw 4 is tightened at that position to bring the tip portion into contact with the rod-like member 2. This is to prevent the screwing from loosening.

  Next, a mounting structure for connecting a beam member, which is a structure of a tree house, to a base tree will be described. 3A shows a cross-sectional view of a form in which a basic tree and a beam are joined using a fixing bracket of the present invention, and FIG. 3B shows a form in which a base tree and a beam are joined using a fixing bracket of the present invention. Is shown in an elevation view. As shown in FIG. 3A, first, the basic tree including the stopper member 3 including the long screw groove 2a of the rod-like member 2 in the form in which the stopper member 3 is screwed to the central portion 2c of the rod-like member 2 is used. Embed in. Next, the fixing bracket 1 is fixed to the base joint portion of the structural member (beam) of the house for attaching the fixing bracket 1 to the tree by the fixing tool 6 such as a bolt through the mounting hole 1c of the fixing bracket 1 of the present invention shown in FIG. To do. Then, the groove 1d of the fixture 1 fixed to the beam is moved to the position of the rod-like member 2 embedded in the basic tree, and the protruding rod-like member 2 is passed through the groove 1d. Thereafter, an outer stopper member 5 such as a nut is screwed into the short thread groove 2b of the rod-like member 2. With such a procedure, an attachment structure that allows movement between members of the present invention for connecting a basic tree and a beam as shown in FIG. 3 is realized.

  In a tree house, such an attachment structure for connecting a basic tree and a beam is constructed at all of a plurality of basic connecting portions. In a form in which one screw 2a of the rod-like member 2 is embedded and fixed in the base member, the rod-like member 2 is passed through the groove portion 1d of the fixing bracket, and the outer stopper member 5 is screwed to the other screw portion 2b. Since the mounting hole 1c of the fixture 1 is fixed to the beam member via the fixture 6, in the engagement relationship between the fixture 1 and the rod-like member 2, the longitudinal direction of the slot 1d is long. Large relative displacement can be tolerated, which will allow relative displacement between the base tree and the other house structure. A plurality of such basic joints are scattered, but the relative displacement of each is different from the special circumstances of the tree house as described above. Each displacement can be absorbed by the mounting structure that allows movement between members of the present invention at each foundation joint, but if any foundation joint exceeds the allowable displacement Even if there is nothing, the mounting structure of the present invention acts as a mechanism that can accommodate each other as long as the allowable displacement of other foundation joints is sufficient, so that an unreasonable load is applied to the house structure. Will be less. For this reason, damage and consumption of the tree house can be suppressed as much as possible.

In addition, in the mounting structure that allows movement between the members of the present invention, the distance between the member surface on which one screw is fixed and the mounting position of the stopper member is larger than the depth dimension of the groove portion of the fixing bracket. The diameter of the rod-shaped member is more preferably smaller than the width dimension of the groove portion of the fixture. Basically, the relative displacement between the members occurs in a three-dimensional manner, and it will be understood that the horizontal displacement is particularly large and the vertical fluctuation is small considering the fluctuation of the underlying tree. For this reason, the relative displacement of the foundation joint portion in the tree house cannot be absorbed only by the longitudinal clearance of the long hole groove 1d of the fixture 1. A clearance equivalent to the longitudinal clearance of the long hole groove 1d is also required in the direction perpendicular to the horizontal direction. In the present invention, it is realized that the distance between the mounting surface of the member surface on which one screw is fixed and the stopper member is larger than the depth dimension of the groove portion of the fixing bracket, that is, the rod-shaped member 2 This is the presence of a central round bar portion 2c in which the thread groove is not cut. As shown in FIG. 3A, the fixture 1 fixed to the beam is engaged with the rod-like member 2 in a form that can move between the stopper member 3 and the outer stopper 5 embedded in the basic tree. This clearance functions to absorb a horizontal displacement component orthogonal to the longitudinal component of the long hole groove 1d. It functions to distribute and absorb two-dimensional displacement with an XY clearance mechanism orthogonal to each other.
Furthermore, in the mounting structure that allows movement between members of the present invention, a configuration is adopted in which the diameter of the rod-shaped member is smaller than the width dimension of the groove portion of the fixture. This dimensional difference absorbs the displacement in the vertical direction.

  FIG. 4 shows a photograph of the construction site of a mounting structure using a fixing bracket that allows movement between members of the present invention. One screw part 1a of the rod-like member 2 to which the inner stopper member 3 is attached is embedded in the basic tree, and the rod-like member 2 protruding outward is fixed to the beam of the tree house by bolting the mounting holes 1c on both sides. A groove 1d of the metal fitting 1 is fitted, and a hexagon nut as the outer stopper member 5 is screwed into the screw portion 1b on the other end side. Two hexagon nuts which are the outer stopper members 5 are screwed together in a connected form, in order to prevent the nuts from loosening. A washer is interposed between the fixing bracket 1 and the outer stopper member 5.
