Description

  The present invention relates to the structure of a wooden house. More specifically, the present invention relates to a connection structure between a horizontal member such as a beam or a girder and a column disposed below the horizontal member.

  Most of the detached houses in Japan are wooden houses, and are often constructed using a method called the conventional method. This conventional construction method basically forms the basics of a building structure with shaft materials such as columns, beams, girders, bracings, and additionally attaches surface materials such as walls, floors, and ceilings to shaft members, Complete the building. That is, the basis of the structure is a shaft material such as a pillar, beam, girder, bracing, etc., and surface materials such as walls, floors, and ceilings have an auxiliary role.

  In these conventional construction methods, structural materials such as pillars, beams, bracing, etc. are difficult to remove or change, but surface materials such as walls, floors, ceilings, studs, windows, etc. are removed or removed. Even if changes such as relocation are made, there is little structural impact on the building itself. Therefore, it is possible to make the opening area of a window or the like larger than the two-by-four method that obtains the strength of the entire wall. Moreover, since the removal and transfer of the wall can be performed relatively freely, it is convenient for renovation because the room layout can be changed.

  In this way, the conventional construction method is a construction method that has many features in addition to history and tradition, but comparing only the strength aspect, even with the same wooden structure, it is structured with a `` face '' in which pillars and wall materials are integrated It is said to be inferior to the two-by-four method of forming the body. In response to this, with the recent development of surface materials such as plywood and various metal fittings, by adopting these new structures, various layouts and designs such as Western-style as well as Japanese-style are maintained without changing the conventional features. It can be used, and continues to be widely adopted as the structure of detached houses in modern times.

  However, although the floor plan can be changed, there are restrictions on the movement and removal of the pipe column and the column, apart from the wall. In particular, there are severe restrictions on the movement and removal of pipe columns that are structural materials. The reason is derived from the roof structure called “Wagoya” unique to the conventional construction method.

  In the following, “tube pillar” refers to a pillar that is installed on each floor from a base to a waistline or from a waistline to an eaves girder in a wooden building. The “through pillar” means a seamless pillar that runs from the base to the eaves girder. Furthermore, the “intermediate pillar” refers to a small pillar that stands between the pillars, and is used to attach a woodcutter or the like that constitutes the wall base.

  20 and 21 are diagrams showing a framework of a house according to a conventional example. 20 and FIG. 21, each symbol indicates a horizontal member 50 such as a beam or a girder, a pipe column 60, a Japanese hut 70, a through column 80, and a base 90. As shown in FIG. 20, the total weight of the Japanese hut 70 acts on the horizontal member 50 installed between the column upper ends, and as a result, the horizontal member 50 bends. This load also acts on the pipe column 60 installed immediately below the horizontal member 50. That is, the pipe column 60 supports part of the weight of the Japanese hut 70 together with the through columns 80 located at the four corners of the building.

  This is because the horizontal member 50 and the pipe column 60 are completely fixed by the tenon (not shown) and the connection fitting 7 as shown in the diagram showing the connection structure of FIG. This is because it also becomes a burden on the pipe column 60. Therefore, if the tube column 60 is carelessly moved or removed, the horizontal member 50 may bend and cause problems such as a crack in the wall. Therefore, when the pipe column 60 is moved or removed, it is necessary to newly stand in another part in order to compensate for the decrease in strength.

  In addition, as shown in FIG. 21, when the first-floor pipe column 60 does not exist immediately below the pipe column 60 installed on the second floor, a bending moment acts on the horizontal member 50 on the first floor, Cause cracks in the wall.

  Further, the fact that the weight of the Japanese hut 70 acts to cause the horizontal member 50 to bend also affects the studs that are non-structural materials. As shown in FIG. 23, when bending occurs in the horizontal member 50, a load is applied via the intermediate pillar 61, and bending occurs in the duck 51. If it does so, the space | interval of the Kamoi 51 and the threshold 52 will become narrow, and it will become difficult to open and close the sliding doors 8, such as a bag and a shoji. Such an effect similarly occurs in the case of a window, and may occur in a door although it is less than a sliding door. It is especially likely to occur in older buildings.

  On the other hand, Patent Document 1 describes an invention in which a gap is provided between a horizontal member and an upper portion of a stud. As shown in FIG. 24, a gap is provided between the horizontal member 50 and the spacer 62, and even if the horizontal member 50 is bent, the spacer 62 and the duck 51 are affected. Therefore, there is no possibility that the opening / closing of the sliding door 8 will be affected.

Japanese Patent No. 2910991

There are the following problems with the conventional connection structure between the horizontal member and the tube pillar or the stud.
(1) It is difficult to move and remove after construction.
Since the load is always applied to the pipe column, if the position of the pipe column changes, the position of the horizontal members such as beams and girders also changes, and the entire building may be distorted, causing problems such as cracks and rain leaks. There is. Therefore, the pipe column cannot be moved or removed by remodeling or the like, and the renovation must be performed within a range in which the tube column is not moved or removed. The inter-column is a non-structural material, so its impact is small compared to the tube column, but if it is moved or removed, the horizontal member may move slightly, which may cause problems such as cracks in the outer wall. After all, in remodeling, it is usually limited to a range in which the position of the pillar is not changed.

(2) Opening / closing of sliding doors, windows, doors, etc. may be hindered.
If the horizontal members such as beams and girders are slightly bent, they will be transmitted to the studs and the duck will be lowered, making it difficult to open and close the sliding doors.

(3) The strength of the wall decreases.
As in the invention described in Patent Document 1, when a gap is provided between the horizontal member and the stud, there is a merit that the bending of the horizontal member can be absorbed within the range of the gap. Since there is nothing between the studs, the studs themselves are unstable, and when an external force is applied by an earthquake or strong wind, the walls are deformed and cracks and breakage are likely to occur.

(4) Strength of horizontal members such as beams and girders is required.
If there is no first-floor pipe column directly under the second-floor pipe column, the bending moment will always act on the horizontal member between the first and second floors. Need to be strong.

  The present invention solves the above-described conventional problems, and does not affect the column due to the bending of a horizontal member such as a beam or a girder, and can be moved and removed after construction. The connection structure is provided.

  The connecting structure between the horizontal member and the column according to the first aspect of the invention is such that the horizontal member such as a beam and a girder and the column disposed below the horizontal member are connected by a connecting member. And a gap between the lower surface of the horizontal member and the upper surface of the column, a relative position between the connecting member and the horizontal member, and a relative position between the connecting member and the column. It is possible to displace at least one of them in the vertical direction, and the connecting member regulates the displacement of the horizontal relative position between the horizontal member and the column.

  The invention according to claim 2 is the connecting structure of the horizontal member and the column according to claim 1, wherein the upper end portion of the connecting member is inserted into a hole formed in the lower surface of the horizontal member, A gap is provided between the upper end of the connecting member and the hole formed in the lower surface of the horizontal member in a state where the lower end is inserted into the hole formed in the upper surface of the column.

  The invention according to claim 3 is the connecting structure between the horizontal member and the column according to claim 1, wherein the upper end portion of the connecting member is inserted into a hole formed in the lower surface of the horizontal member, A gap is provided between the lower end of the connecting member and the hole formed in the upper surface of the column in a state where the lower end is inserted into the hole formed in the upper surface of the column.

  The invention according to claim 4 is the connecting structure between the horizontal member and the column according to claim 2 or claim 3, wherein the depth of the hole formed in the upper surface of the column, the lower surface of the horizontal member, and the column The sum of the gaps between the upper surface and the upper surface of the connecting member is not less than the length of the connecting member in the vertical direction.

  The invention according to claim 5 is the connecting structure between the horizontal member and the column according to claim 1, wherein the upper end portion of the connecting member is fixed to the lower surface of the horizontal member, and the lower end portion of the connecting member is the column. A gap is provided between the lower end of the connecting member and the hole formed in the upper surface of the column in a state of being inserted into the hole formed in the upper surface of the column.

  According to the first aspect of the present invention, since the gap is provided between the lower surface of the horizontal member such as a beam or a girder and the upper surface of the column disposed below the horizontal member, the horizontal member is bent. Even if this occurs, as long as it is within the gap, the lower surface of the horizontal member does not come into contact with the upper surface of the column and will not be affected. In addition, since at least one of the relative position between the connecting member and the horizontal member and the relative position between the connecting member and the column can be displaced in the vertical direction, even if the horizontal member is bent, it can be displaced. If so, the pillar is not affected via the connecting member. By these, it is possible to prevent the influence of the bending of the horizontal member from being transmitted to the column. Therefore, it is possible to move and remove the pillar after the construction, and it is possible to widen the range of reform.

  In addition, since the displacement of the horizontal relative position between the horizontal member and the column is regulated by the connecting member, the strength of the column with respect to the horizontal external force can be increased.

  According to the second aspect of the present invention, the upper end of the connecting member is inserted into the hole formed in the lower surface of the horizontal member, and the lower end of the connecting member is inserted into the hole formed in the upper surface of the column. In this state, since a gap is provided between the upper end of the connection member and the hole formed in the lower surface of the horizontal member, if the horizontal member is bent, the gap is used to connect the connection member and the horizontal member. It becomes possible to displace the vertical relative position of the material, and it is possible to prevent the influence of the bending of the horizontal member from being absorbed by the gap and transmitted to the column.

  According to the invention described in claim 3, the upper end of the connecting member is inserted into the hole formed in the lower surface of the horizontal member, and the lower end of the connecting member is inserted into the hole formed in the upper surface of the column. In this state, a gap is provided between the lower end of the connecting member and the hole formed in the upper surface of the column. Therefore, when the horizontal member is bent, the gap is used to make the vertical direction of the connecting member and the column. The relative position of the horizontal member can be displaced, and the influence of the bending of the horizontal member can be absorbed by the gap and transmitted to the column.

  According to the invention described in claim 4, the depth of the hole formed in the upper surface of the column and the sum of the gaps between the lower surface of the horizontal member and the upper surface of the column are the length of the connecting member in the vertical direction. Therefore, after laying a horizontal member such as a beam or a girder, the column can be erected with the connecting member placed in the hole, and then the connecting member can be pulled out from the hole and installed. Moreover, when moving a pillar, it can be moved in the state which put the pulled-out connection member in the hole again, and can be reused without cut | disconnecting a connection member.

  According to the invention described in claim 5, the connecting member is fixed in a state where the upper end portion of the connecting member is fixed to the lower surface of the horizontal member and the lower end portion of the connecting member is inserted into the hole formed in the upper surface of the column. Since a gap is provided between the lower end of the column and the hole formed in the top surface of the column, when the horizontal member is bent, the vertical relative position of the connecting member and the column is displaced using this gap. Therefore, it is possible to prevent the influence of the bending of the horizontal member from being absorbed by the gap and transmitted to the column. Furthermore, since no hole is formed on the lower surface of the horizontal member, it is advantageous in terms of strength of the horizontal member.

  As described above, according to the present invention, it is possible to provide a connecting structure between a horizontal member and a column that can be moved and removed after construction without affecting the column by the influence of bending of the horizontal member such as a beam or a girder. Can do.

  Next, with reference to FIG. 1 thru | or FIG. 4, the connection structure of the horizontal member which concerns on Embodiment 1 of this invention and a column is demonstrated. 1 is an exploded cross-sectional view showing a connecting structure between a horizontal member and a pillar according to Embodiment 1, FIG. 2 is an exploded perspective view showing a pillar and a connecting member according to Embodiment 1, and FIG. FIG. 4 is a cross-sectional view illustrating a connection structure between a horizontal member and a column according to the first embodiment, and FIG. 4 is a front view illustrating a connection structure between the horizontal member and the column according to the first embodiment.

  As shown in FIGS. 1 and 2, the connecting structure between the horizontal member and the pillar according to the first embodiment includes a horizontal member 10 such as a beam and a girder, a column 20 disposed below the horizontal member 10, and a horizontal member. The connecting member 30 connects the base member 10 and the column 20.

  A hole 12 for inserting the upper end 31 of the connection member 30 is formed on the lower surface 11 of the horizontal member 10. Further, a hole 22 for inserting the lower end 32 of the connection member 30 is formed in the upper surface 21 of the column 20. On the other hand, the connecting member 30 is a long rod-like member, and the material is not particularly limited, but a reinforcing bar such as round steel, a wooden or resin dowel, a metal pin, a metal pipe, or the like can be used. Further, the sizes of the hole 12 and the hole 22 have a slight gap that is movable in the vertical direction when the connecting member 30 is inserted. The cross-sectional shapes of the holes 12 and 22 and the connection member 30 are not necessarily circular, and may be appropriate cross-sectional shapes such as a triangle, a quadrangle, and a cross shape.

  As shown in FIG. 3, in the connection structure of the first embodiment, first, a gap X is provided between the lower surface 11 of the horizontal member 10 and the upper surface 21 of the column 20. The size of the gap X varies depending on the strength of the beams and girders of the building, but is slightly larger than the expected amount of bending of the horizontal member 10.

  On the other hand, the connecting member 30 is not fixed to either the horizontal member 10 or the column 20, and the lower end portion 32 of the connecting member 30 is in contact with the bottom surface of the hole portion 22 of the column 20 by gravity. A gap Y is provided between the upper end 31 of the connecting member 30 and the hole 12 formed in the lower surface 11 of the horizontal member 10 (between the ceiling surface of the hole 12). As with the gap X, the size of the gap Y also varies depending on the strength of the beams and girders of the building, but is slightly larger than the expected amount of bending of the horizontal member 10. As shown in FIG. 4, when viewed from the outside, a part of the connection member 30 can be seen between the horizontal member 10 and the column 20.

  In order to install the horizontal member 10 and the column 20 as in the connection structure of the first embodiment, the column 20 is first installed, and the lower end portion 32 of the connection member 30 is inserted into the hole portion 22 of the column 20. From above, the horizontal member 10 is bridged from above, and the upper end portion 31 of the connecting member 30 is inserted into the hole 12 of the horizontal member 10. Further, when the column 20 is moved or removed, the connecting member 30 is cut.

  In the connection structure of the first embodiment, when a load is applied to the horizontal member 10 to cause bending and hang downward, the gap X in FIG. 3 is reduced, but the lower surface of the horizontal member 10 is within the range of the gap X. 11 and the upper surface of the pillar 20 do not contact. At the same time, the gap Y also shrinks. However, as long as the gap Y is within the range, the upper end portion 31 of the connection member 30 and the hole 12 of the horizontal member 10 (the ceiling surface of the hole 12) do not contact each other.

  Further, the connecting member 30 is inserted into the hole 12 of the horizontal member 10 and the hole 22 of the column 20 so that the displacement of the horizontal relative position between the horizontal member 10 and the column 20 is regulated. Thus, even if a horizontal external force is applied to the pillar 20, it can withstand to some extent.

  According to the connecting structure between the horizontal member and the column according to the first embodiment, the lower surface 11 of the horizontal member 10 such as a beam or a girder and the upper surface 21 of the column 20 disposed below the horizontal member 10. Since the gap X is provided, even if the horizontal member 10 is bent, the lower surface 11 of the horizontal member 10 does not come into contact with the upper surface 21 of the column 20 so long as it is within the range of the gap X. .

  Further, the upper end portion 31 of the connecting member 30 is inserted into the hole portion 12 formed in the lower surface 11 of the horizontal member 10, and the lower end portion 32 of the connecting member 30 is inserted into the hole portion 22 formed in the upper surface 21 of the column 20. Since the gap Y is provided between the upper end portion 31 of the connecting member 30 and the hole 12 formed in the lower surface 11 of the horizontal member 10, when the horizontal member 10 is bent, the gap Y is used. Thus, the relative position in the vertical direction of the connecting member 30 and the horizontal member 10 can be displaced, and the influence of the bending of the horizontal member 10 can be absorbed by the gap Y and transmitted to the column 20 can be prevented. .

  Further, since the displacement of the horizontal relative position between the horizontal member 10 and the column 20 is regulated by the connecting member 30, the strength of the column 20 against the external force in the horizontal direction can be increased.

  FIG. 5 is a view showing a framework of a house to which the connecting structure of the horizontal member and the pillar according to the present embodiment is applied. The weight of the Japanese hut 70 is transmitted to the horizontal member 10 on the second floor, but is not transmitted to the pillar 20 (tube pillar) on the second floor, but only to the through pillar 80. Moreover, what is transmitted to the horizontal member 10 on the first floor is about the weight of the second floor and the pillar 20 (tube pillar) on the second floor, and the weight of the Japanese hut 70 is released. Furthermore, there is no weight burden on the pillar 20 (tube pillar) on the first floor.

  Depending on the size of the building, as shown in FIG. 6, in addition to the through pillars 80 at the four corners of the building, a conventional tube pillar 60 having no gap is appropriately provided to reduce the burden on the horizontal member 10. You may make it do.

  Next, with reference to FIG. 7, the connection structure of the horizontal member and column which concerns on Embodiment 2 of this invention is demonstrated. FIG. 7 is a cross-sectional view illustrating a connection structure between a horizontal member and a column according to the second embodiment. In the following embodiments, the same components as those of the first embodiment are denoted by the same reference numerals and description thereof is omitted.

  In the second embodiment, the connection member 30 inserted into the hole 22 of the column 20 is fixed to the column 20 with the fixing screw 1. Thereby, the relative position of the connecting member 30 and the pillar 20 in the vertical direction cannot be displaced. However, the upper end portion 31 of the connection member 30 can move in the vertical direction inside the hole 12 of the horizontal member 10, and the vertical relative position of the connection member 30 and the horizontal member 10 can be displaced.

  Also by the connection structure of the horizontal member and the column according to the second embodiment, the same operational effects as those of the first embodiment can be obtained.

  Next, with reference to FIG.8 and FIG.9, the connection structure of the horizontal member and column which concern on Embodiment 3 of this invention is demonstrated. FIG. 8 is a cross-sectional view illustrating a connecting structure between a horizontal member and a column according to the third embodiment, and FIG. 9 is a front view illustrating a connecting structure between the horizontal member and the column according to the third embodiment.

  In the third embodiment, the connection member 30 is pulled upward, and the upper end 31 is fixed to the horizontal member 10 with the fixing screw 2 in a state where the upper end 31 is in contact with the ceiling surface of the hole 12 of the horizontal member 10. . Thereby, the vertical relative position of the connecting member 30 and the horizontal member 10 cannot be displaced. However, the lower end portion 32 of the connecting member 30 can move in the vertical direction inside the hole portion 22 of the column 20, and the relative position in the vertical direction between the connecting member 30 and the column 20 can be displaced.

  Further, a gap Z is provided between the lower end portion 32 of the connecting member 30 and the hole portion 22 of the column 20 (between the bottom surface of the hole portion 22).

  According to the connecting structure of the horizontal member and the column according to the third embodiment, the upper end portion 31 of the connecting member 30 is inserted into the hole 12 formed in the lower surface 11 of the horizontal member 10, and the lower end portion 32 of the connecting member 30 is Since the gap Z is provided between the lower end portion 32 of the connection member 30 and the hole portion 22 formed in the upper surface 21 of the column 20 in a state of being inserted into the hole portion 22 formed in the upper surface 21 of the column 20, the horizontal member 10 is deflected, the gap Z can be used to displace the vertical relative position of the connecting member 30 and the column 20, and the influence of the deflection of the horizontal member 10 can be absorbed by the gap Z. Propagation to the pillar 20 can be prevented.

  Next, with reference to FIG. 10, the connection structure of the horizontal member and column which concerns on Embodiment 4 of this invention is demonstrated. FIG. 10 is a cross-sectional view illustrating a connection structure between a horizontal member and a column according to the fourth embodiment.

  In the fourth embodiment, the hole 13 formed in the lower surface 11 of the horizontal member 10 penetrates to the upper surface of the horizontal member 10.

  Also by the connecting structure of the horizontal member and the pillar according to the fourth embodiment, the same operational effects as those of the first embodiment can be obtained. Furthermore, in Embodiment 4, after the horizontal member 10 is laid, the column 20 can be installed, and the connecting member 30 can be inserted from the upper surface of the horizontal member 10 and installed. When the column 20 is moved and removed, the connecting member 30 can be extracted from the upper surface of the horizontal member 10.

  Next, with reference to FIG. 11 thru | or FIG. 13, the connection structure of the horizontal member and pillar which concerns on Embodiment 5 of this invention is demonstrated. FIG. 11 is a cross-sectional view showing a state before connection of the connecting structure between the horizontal member and the column according to the fifth embodiment, and FIG. 12 is a cross-sectional view showing the connecting structure between the horizontal member and the column according to the fifth embodiment. FIG. 13 is a front view showing a connection structure between a horizontal member and a column according to the fifth embodiment.

  In the fifth embodiment, the sum of the depth of the hole 23 formed in the upper surface 21 of the column 20 and the gap X between the lower surface 11 of the horizontal member 10 and the upper surface 21 of the column 20 is the vertical of the connecting member 30. It is longer than the length of the direction. Therefore, as shown in FIG. 11, the upper end portion 31 of the connection member 30 inserted in the hole 23 of the column 20 does not reach the lower surface 11 of the horizontal member 10 in a state before connection. At the time of connection, as shown in FIGS. 12 and 13, the connecting member 30 is pulled upward, and the upper end 31 is brought into contact with the ceiling surface of the hole 12 of the horizontal member 10, and the fixing screw 3 is used. It is fixed to the horizontal member 10. Thereby, the vertical relative position of the connecting member 30 and the horizontal member 10 cannot be displaced. However, the lower end portion 32 of the connection member 30 can move in the vertical direction inside the hole 23 of the column 20, and the relative position of the connection member 30 and the column 20 in the vertical direction can be displaced.

  Further, a gap Z is provided between the lower end portion 32 of the connection member 30 and the hole portion 23 of the column 20 (between the bottom surface of the hole portion 23).

  Even with the connecting structure between the horizontal member and the pillar according to the fifth embodiment, the same effects as those of the third embodiment can be achieved. Further, in the fifth embodiment, the depth of the hole 23 formed in the upper surface 21 of the column 20 and the sum of the gaps X between the lower surface 11 of the horizontal member 10 and the upper surface 21 of the column 20 are Since it is longer than the length in the vertical direction, after laying the horizontal member 10 such as a beam or a girder, the column 20 is erected in a state where the connecting member 30 is put in the hole 23, and then the connecting member 30 is moved to the hole 23. It can be pulled out from the installation. When the pillar 20 is moved, the connected connecting member 30 can be moved in a state where it is put in the hole 23 again, and the connecting member 30 can be reused without being cut. In FIG. 11, since the depth of the hole 23 and the length of the connection member 30 are the same, the upper end 31 of the connection member 30 does not protrude from the upper surface 21 of the column 20, but of course within the range of the gap X. If there is, it may protrude. In that case, the connecting member 30 can be easily pulled out by using the protruding portion.

  Next, with reference to FIG.14 and FIG.15, the connection structure of the horizontal member and column which concerns on Embodiment 6 of this invention is demonstrated. FIG. 14 is a cross-sectional view showing a column and a connecting member according to Embodiment 6, and FIG. 15 is a perspective view showing the column and a connecting member according to Embodiment 6.

  As shown in FIGS. 14 and 15, the pillar 20 according to the sixth embodiment has a long hole 24 formed in the side surface and a recess 25 formed in the hole 23. A through hole 33 is formed below the connection member 30. An operation pin 4 is inserted into the long hole 24.

  In the sixth embodiment, the connecting member 30 placed in the hole 23 of the column 20 is pulled out upward as follows. First, as shown in FIG. 14A, the tip of the operation pin 4 inserted into the long hole 24 is inserted partway through the through hole 33 formed in the connection member 30. In this state, as shown in FIG. 14B, the operation pin 24 is pulled up and the connecting member 30 is pulled out upward. And as shown in FIG.14 (c), the front-end | tip of the operation pin 4 is penetrated to the through-hole 33, and it fits in the recessed part 25 formed in the hole 23. FIG. As described above, the connection member 30 is fixed in a state of being pulled out upward. When the column is removed and moved, if the operation pin 4 is pulled out, the operation pin 24 and the recess 25 are disengaged, and the connection member 30 falls downward and is accommodated in the hole 23 of the column 20 again.

  Also by the connecting structure of the horizontal member and the pillar according to the sixth embodiment, the same operational effects as those of the fifth embodiment can be obtained. Furthermore, in the sixth embodiment, the connecting member 30 can be easily pulled out and fixed.

  Next, with reference to FIG. 16 thru | or FIG. 18, the connection structure of the horizontal member and column which concern on Embodiment 7 of this invention is demonstrated. FIG. 16 is a cross-sectional view showing a state before connection of the connecting structure between the horizontal member and the column according to the seventh embodiment, and FIG. 17 is a cross-sectional view showing the connecting structure between the horizontal member and the column according to the seventh embodiment. FIG. 18 is a perspective view showing a connection member according to the seventh embodiment.

  In the seventh embodiment, no hole is formed in the lower surface 11 of the horizontal member 10. Further, a T-shaped connection member 40 is used as the connection member. As shown in FIG. 18, the connecting member 40 is composed of a plate material 43 and a bar material 44. In the seventh embodiment, as shown in FIG. 16, in the state before connection, the portion of the bar 44 of the connecting member 40 is inserted into the hole 22 of the column 20, and the portion of the plate member 43 covers the upper surface 21 of the column 20. It comes to cover. At the time of connection, as shown in FIG. 17, the connection member 40 is pulled upward, and the upper end portion 41 is in contact with the lower surface 11 of the horizontal member 10 and is fixed to the horizontal member 10 with the fixing screw 5. ing. Thereby, the relative position of the connection member 40 and the horizontal member 10 in the vertical direction cannot be displaced. However, the lower end portion 42 of the connection member 40 can move in the vertical direction inside the hole portion 22 of the column 20, and the relative position in the vertical direction between the connection member 40 and the column 20 can be displaced.

  Further, a gap Z is provided between the lower end portion 42 of the connecting member 40 and the hole portion 22 of the column 20 (between the bottom surface of the hole portion 22).

  According to the connecting structure of the horizontal member and the column according to the seventh embodiment, the upper end portion 41 of the connecting member 40 is fixed to the lower surface 11 of the horizontal member 10, and the lower end portion 42 of the connecting member 40 is fixed to the upper surface 21 of the column 20. Since the gap Z is provided between the lower end portion 42 of the connecting member 40 and the hole portion 22 formed in the upper surface 21 of the column 20 in a state of being inserted into the formed hole portion 22, the horizontal member 10 is bent. In this case, the gap Z can be used to displace the relative position of the connecting member 40 and the column 20 in the vertical direction, and the influence of the bending of the horizontal member 10 can be absorbed by the gap Z and transmitted to the column 20. Can be prevented. Furthermore, since no hole is formed on the lower surface of the horizontal member 10, the strength of the horizontal member 10 is advantageous.

  In addition, using the connection member 40 in Embodiment 7 upside down, the upper end part (bar part) of the connection member is inserted into the hole 12 formed in the lower surface 11 of the horizontal member 10, and the lower end part of the connection member With the (plate member portion) fixed to the upper surface of the column 20, between the upper end portion (bar member portion) of the connecting member and the hole portion 12 formed in the lower surface 11 of the horizontal member 10 (the ceiling of the hole portion 12). Even if the gap Y is provided between the surface and the surface, the same effect can be obtained.

  Further, in the above embodiment, as shown in FIG. 19, in order to shield the gap X between the lower surface 11 of the horizontal member 10 and the upper surface 21 of the column 20 from the outside, the load from the horizontal member 10 is changed to the column. You may make it fill with the soft flexible member 6 of the grade which is not transmitted to 20.

  As described above, according to the embodiment, it is possible to provide a connection structure between the horizontal member 10 and the column 20 that does not affect the column 20 due to the bending of the horizontal member 10 such as a beam or a girder. Therefore, the following effects can be obtained by applying to beams, girders, pipe columns, and studs.

(1) Easy to move and remove after enforcement.
Since the load from above does not act on the tube column and the inter-column, even if these positions change, the load applied to the beam and girder does not change greatly. Therefore, the entire building is not distorted, and there is no fear of problems such as cracks and rain leaks. In renovation and the like, since the pipe column can be easily moved and removed, it is possible to move and remove the pipe column as well as the intermediate column, and the layout can be greatly changed by changing the position of the pipe column.

(2) There is no hindrance to opening and closing sliding doors, windows, doors, etc.
Even if bending of beams and girders occurs, the duck is not lowered, and opening and closing of the sliding doors is smooth.

(3) Wall strength reduction is minimal.
Although there are gaps between the beams and girders and the pipe columns and studs, the displacement of the relative position in the horizontal direction is restricted by the connecting members, so even if an external force is applied due to an earthquake or strong wind, the deformation of the wall is minimal. Stay on.

(4) The strength of beams and girders is not required.
Since the weight of the roof does not act on the beams and girders between the first and second floors, there is no need to particularly strengthen the beams and girders between the first and second floors.

  In addition, in the said embodiment, although it was set as the structure which inserts the edge part of a connection member in the hole formed in a horizontal member or a pillar, it is not limited to this in particular, A connection member, a horizontal member, Other configurations may be used as long as at least one of the relative positions of the connecting members and the pillars can be displaced in the vertical direction. With such a configuration, even if the horizontal member is bent, if the vertical relative position can be displaced, the bending of the horizontal member may affect the column via the connecting member. There is no.
