Description

The present invention relates to a structural planning method for creating an open interior space with free partitioning in a construction method technology for a wooden house. By obtaining an open interior space that does not require or reduces the internal wall and arranging a partition wall that can be freely arranged in the open interior space, it is possible to easily change the partition by free partitioning and rearrangement. Regarding the technique of the method.

As a general construction method for wooden buildings, there is a conventional frame construction method. The conventional framework construction method is a construction method that is mainly supported by frameworks such as columns and beams. Compared to the frame wall construction method, there are fewer walls to give strength, so this construction method has a relatively high degree of freedom in design. However, in order to ensure seismic resistance, it is necessary to make heavy use of diagonal members such as braces, flint beams, and flint bases.

Although the frame construction method has a high degree of freedom in design, members of various dimensions are used depending on the shape of the wooden building, and they may be assembled in a complicated manner. As the types of materials increased, the construction method became complicated, the number of work processes increased, and as a result, the construction period became longer.

In addition, in the conventional construction method, there is a tendency to use a lot of braces on the wall in order to improve the seismic resistance, and the number of parts where the heat insulating material cannot be uniformly filled in the wall increases, and a sufficient heat insulating effect cannot be obtained. many. In addition, the floor and ceiling were not sufficiently filled with the heat insulating material, so that a sufficient heat insulating effect could not be obtained.

In addition, when constructing a hut or roof, there is only a work space above the hut beams and main building, and workers are forced to do dangerous work, and there is a high possibility of a fall accident due to stepping off, so safe and efficient work can be done. It was an extremely difficult situation. Therefore, there is also a demand for a construction method that simplifies the structure, improves seismic resistance and heat insulation, and ensures safety during roof construction.

Furthermore, in recent modern houses, there is a tendency to use a large space for multiple purposes even if it is made of wood. The living / dining / kitchen is a continuous space or one room, and the tendency is the same in a private space, and the usage divided into small rooms makes you feel the negative image of confining an individual in a closed space. , It seems that young people who are going to build a family life are shunned. If it is a tradition of Japanese houses to divide a large space with simple partitions such as shoji and sliding doors and use it for "multipurpose use", it may be said that it is an "ancestor return" that returns to the old appearance. However, in a Japanese wooden house that combines small rooms made of small parts, it is difficult to make an open / continuous space a "multipurpose use". It may be natural to divide the space into small pieces in order to solve seismic performance and energy saving performance, but it will be inconsistent with the open space.

Furthermore, in general detached houses, the floor plan is often fixed in advance and the building design is based on the floor plan. Then, a situation occurs in which inconvenience occurs. Furthermore, when selling a building, there is also the problem that a large-scale construction work is required to change the floor plan in the next renovation of the resident.

In view of the above problems, various technical proposals have been made in the past. Regarding the wooden frame construction method, for example, a load-bearing ceiling wall structure (see Patent Document 1) of a wooden house utilizing the ceiling plate material of the wooden house as a strength member of the wooden house has been proposed and is a known technique. More specifically, in a skeleton framed by a pillar, a base, a beam, a girder, or the like, the opening formed by the hut beam or the girder overlaps with the peripheral edge of the ceiling plate material for closing the opening by a predetermined width, and is described above. A notch having a depth substantially equal to the plate thickness of the ceiling plate material is formed, the peripheral edge of the ceiling plate material is fitted into the notch, and the ceiling plate material is pulled by a fixing means such as a nail to form the opening. It is a durable ceiling wall structure of a wooden house, which is characterized by being fixed to a small beam.
Although it is stated that the strength of the ceiling will be increased, there is no description about the improvement of roofing workability by changing the construction procedure and the simplification of the building structure, which has led to the solution of the above problem. Not in.

In addition, technology for improving the airtightness, workability, heat insulation, and seismic strength of the ceiling structure (see Patent Document 2).
Has been proposed and has become a known technique. More specifically, in a ceiling structure in which panels are interposed between beams of a house or between beams of a shed laid between girders, the panel is composed of a face material and a foamed heat insulating material, and is located in the center of one side of the face material. The foamed heat insulating material is integrally joined to each other, leaving the outer peripheral portion of the face material, and the face material is brought into contact with the hut beam from the back side of the hut or from the indoor side to the hut beam and fixed. It is a structure in which panels are constructed.
Although the improvement of the heat insulating property of the ceiling is described, the improvement of the earthquake resistance and the free partition are not described, and the above-mentioned problem has not been solved yet.

Further, a technique for providing a ceiling construction method and a ceiling panel (see Patent Document 3) has been proposed, which enables the ceiling to be unitized as a ceiling panel and the ceiling can be formed without suspending the ceiling panel from above. , It is a known technology. More specifically, the ceiling panel is constructed by attaching gypsum board plywood to the runners and studs, and at least one work hole is formed in the ceiling panel. This ceiling panel is hung from above the wall panel surrounding the room and fixed to the wall panel. Then, above the ceiling panel, the floor panel is installed at the upper end of the wall panel, and the floor panels adjacent to each other are connected by the floor panel binding bolt inserted from the work hole. Finally, the work hole is closed with an auxiliary gypsum board plywood.
Although it is stated that the ceiling part is strengthened, it is not stated that the earthquake resistance is improved, the open interior space is secured, and the free partitioning and the ease of rearrangement are not described, which has led to the solution of the above problem. Not in.

Further, various techniques have been conventionally proposed for the problem of the partition. For example, the name of the invention is "joining structure of wall panel", and the subject is "providing an efficient and reliable connecting structure between the surface material surface of the wall panel and the side surface of the frame". A face material surface and a buried hole were provided in the connection structure between the frame body side surface and the face material surface of the wall panel consisting of the frame body assembled in a rectangular frame shape and the face materials attached to both the front and back surfaces. Either a male member with a protruding head or a female member with a substantially U-shaped groove is attached to the side surface of the frame, and the buried hole stores both members when both members are engaged. , It has a depth to bring the side surface of the frame body into contact with the surface of the face material. ”, Which is a known technique (see Patent Document 4).

Further, for example, the name of the invention is "construction structure of interior wall", and the problem is "to provide a new construction structure of interior wall with a profound feeling and a sense of quality". Specifically, "architecture". L-shaped angle metal fittings are fixed to pillars, interstitial pillars, etc., which are structures, and cut grooves are provided in them at a constant vertical pitch, and fasteners are attached to them. The technique of engaging with the convex portion of the upper end edge and the concave portion of the lower end edge of the plate-shaped building material to be fitted in phase with each other to fix and support the fitting portion is disclosed and known. It is a technology (see Patent Document 5).

Further, for example, the name of the invention is "joint structure of lattice panel", and the problem is "by using an angle material instead of buried wood, the lattice panel can be fixed to the lattice panel inexpensively and reliably. "We are trying to provide a joint structure of It is a joint structure of lattice panels that are joined and the plaster boards are fixed to at least one side of the lattice panels on the inner corner side, and an angle material is applied to the inner corner portion of the joint between the lattice panels. A technique is disclosed in which the gypsum board is fixed to the frame through the angle member, which is a known technique (see Patent Document 6).

However, in any of the above-mentioned prior arts, free arrangement is not possible, and unlike the present invention, the effect that removal, rearrangement, etc. can be easily performed is not exhibited, and Patent Documents 4 and 6 do not have the effect. , The configuration is complicated in that a frame is required, and in Patent Document 5, since it is fixed to a pipe column , a stud, or the like, the degree of freedom of partitioning is low, and in each case, in order to solve the problem of the present invention. It hasn't arrived.

The present inventor has been working horizontally to solve the problems in the wooden frame construction method, which had been a problem until now, that is, the structural simplification and the securing of the filling area of the heat insulating material by reducing the brace of the bearing wall. Focusing on the structure, a specific three-dimensional area consisting of the horizontal structure, columns, and bearing walls is regarded as one grid, and a plurality of such grids are combined to design the entire building. We have obtained patents for "Manufacturing method" (see Patent Document 7) and "Freely arrangable partition wall and its construction method" (see Patent Document 8) in order to solve problems such as free partitioning. The invention of the present application has been completed by combining these and making improvements.

It is also possible to adopt a configuration using a partition wall that can be freely arranged, which enables free and easy construction and change of the partition.

Changing the floor plan of an existing wooden building cannot avoid structural additions, and wooden buildings that have undergone expansion or renovation or changing the floor plan will definitely be weakened. However, according to the construction method of a building structure that creates an open interior space with free partitions according to the present invention, it is possible to change the floor plan without giving a structural load, and it is possible to flexibly respond to the change of the floor plan due to various requests. However, it exerts an excellent effect that it can be a variable house that can reach the end of the life of the building.

In the construction method of a building structure for creating an open interior space with free partitioning according to the present invention, in the wooden frame construction method, the vertical load and the horizontal load are borne by the two-layer horizontal structure surface and the outer peripheral structural wall, thereby opening the building. The greatest feature is to arrange a partition wall that can be freely arranged so that the inner wall of the interior space becomes unnecessary or reduced and the partition wall can be freely arranged in the open interior space. Hereinafter, examples will be described with reference to the drawings. It should be noted that the overall shape and the shape of each part of the construction method of the building structure for creating the open interior space with free partition shown in this embodiment are not limited to the examples described below, and the technical idea of the present invention.

It is effective in terms of strength.

It is an Example explanatory drawing explaining another example of the construction method 200 of the building structure to build. FIG. 2A shows a plane of an embodiment in which one wide open indoor space 1 such as 22 tatami mats or 40 tatami mats is obtained by combining one indoor space such as 4.5 tatami mats and 8 tatami mats which are square.

First, a construction method 200 of a building structure for creating an open interior space with free partitions will be described. The construction method 200 of a building structure that creates an open interior space with free partitions is a design method that solves problems in the wooden frame construction method. The first problem is that the structural calculation for seismic resistance is a short-form calculation that calculates the number of braces 9, and the grounds for ensuring strength are unclear, resulting in a structure with excessive strength. was there. Secondly, because of the high flexibility of the design, it is difficult to standardize the parts, so the labor in precutting is heavy, and the parts may be processed on site, which prolongs the construction period and leads to an increase in cost. .. Thirdly, there is a tendency to increase the number of braces 9 to be inserted into the wall in order to improve the seismic performance, and therefore, the filling volume of the heat insulating material 13 is lowered, and the heat insulating performance is deteriorated.

In order to solve these problems of the conventional frame construction method, in the construction method 200 of a building structure for creating an open interior space with free partitioning, first, the structural calculation is managed in the open interior space 1. Secondly, at least two layers of the second floor and the beam surface of the hut are designated as the horizontal structure surface 2 using the horizontal structure strengthening plate. Thirdly, partitioning is performed using a partition wall 101 that can be freely arranged so as to enable free partitioning.

Next, the contents of managing the structural calculation in the open interior space 1 will be described. As the unit area, a square open interior space 1 such as 8 tatami mats or 4.5 tatami mats is suitable for calculation, but a rectangle such as 6 tatami mats or 10 tatami mats may be used. If the unit area is square, a member having a common length can be used for the base 4, the large pull 15, or the large beam 5 and the small beam 7, so that the types of members are reduced, the work process is simplified, and the rigidity is reduced. It is possible to stabilize the structural balance by aligning the center of the beam with the center of the weight.

For example, when 40 tatami mats are used as an open interior space 1, a wooden building having the open interior space 1 is planned to include the open interior space 1. The 40 tatami open interior space 1 is not merely an ideal open interior space 1, but is actually designed as a 40 tatami space. For the open interior space 1 of 40 tatami mats, the necessary load-bearing wall arrangement and structural balance will be examined from the rigidity of the upper and lower horizontal structure 2 by calculating the allowable stress. Further, for the other open interior spaces 1 in the wooden building, the horizontal structure 2, the arrangement of the necessary bearing walls, and the structural balance are examined by calculating the allowable stress for each individual open interior space 1. Finally, each open indoor space 1 is combined to make an optimal wooden building as a whole.

The configuration of the open interior space 1 will be described. The open interior space 1 is mainly composed of a horizontal structure 2, a pipe column 8, an outer wall 17 on the first floor, or an outer wall 18 on the second floor. As shown in FIGS. 1, 2, and 3, in the case of a two-story building according to this design method, a horizontal structure 2 using a horizontal structure strengthening plate 3 is arranged above the pipe column 8 as a second floor. Standing unified tubular column 8 of thickness dimension horizontal plane 2 top, through the studs 2 Kaigaiheki 18 is provided on the cabin side of the second floor pipe column 8 upper horizontal plane reinforcing plate 3 The used horizontal structure surface 2 is arranged.

The configuration of the girders 5 and the girders 7 constituting the second floor and the hut floor is adjusted to the dimensions used for the maximum open interior space 1 in the entire building for each open interior space 1. Further, a horizontal structure surface 2 using the horizontal structure surface strengthening plate 3 is installed in the lower part of the cabin where the floor does not originally exist. The weight of the horizontal structure 2 will be heavier than that of the floor of the conventional frame construction method, but the structural balance can be achieved by aligning the center of rigidity and the center of weight of the entire building, and the horizontal structure can be achieved. It is possible to make the reinforcement to compensate for some inconvenience caused by the increase in the weight of the surface 2.

In addition, the length of each floor pipe column 8 is such that the girders 5 and 7 that make up the second floor and the hut floor are formed so that each open interior space 1 matches the dimensions used for the largest open interior space 1 in the entire building. It is possible to make the dimensions the same. Since those floors the same in all tubular column 8 thickness and length co-used in, the tube column 8 is not required location decided, it is possible to be used in Tokai anywhere.

In the conventional shaft assembly method, the joists and the floor base are placed on the base 4 and the large pull 15, and the base 4 and the large pull 15 and the joists and the floor base are fixed to the extent that the nail 6 does not remove the floor base. Is to be done. Therefore, the floor does not constitute the horizontal structure 2. Therefore, in order to improve the strength of the base 4, it is necessary to reinforce it with an oblique member such as a flint base 4. However, in the construction method 200 of a building structure for creating an open interior space with free partitions according to the present invention, it is also possible to make the horizontal structure surface 2 by fitting the horizontal structure surface reinforcing plate 3 to the horizontal member of the floor. , It is possible to improve the strength of the base 4.

By reducing the number of braces 9, the heat insulating effect can be improved. In the bearing wall of this embodiment, if the bracing 9 between but not shown in the drawings two tubular column 8 is installed two on crosswise, is the braces 9 between the tube column 8, the upper Placed below. The outside air-side of the tube column 8 the outer wall is installed, it is effective in the room side of the tube column 8 for installing the reinforcing plate 14 for vertical Plane. When the heat insulating material 13 is to be inserted between the pipe columns 8 in which the two braces 9 are inserted into the crosspiece, the thickness of the braces 9 becomes a problem. For example, when the dimension of the pillar 8 is 105 mm and the dimension of the brace 9 is 45 mm, only the thickness of the heat insulating material 13 of 15 mm or less can be used.

In contrast, although not shown in the drawings, when the muscle wrote 9 is single, the thickness of the heat insulating material 13 can increased to 60 mm. In this way, by reducing the brace 9, the filling area of the heat insulating material 13 can be secured, so that the heat insulating effect of the wall can be greatly improved.

The floor of the second floor is arranged above the pipe pillar 8 on the first floor, and this portion is the horizontal structure 2. This part is the ceiling on the first floor and the floor on the second floor at the same time. The horizontal structure surface 2 is composed of horizontal members such as a girder 5, a small beam 7, and a grandchild beam 16, and a reinforcing plate 3 for a horizontal structure. The horizontal structure reinforcing plate 3 is firmly fixed to the horizontal member by a large number of nails 6.

In the conventional frame construction method, the floor base is arranged on the girder 5 and the girder 7. The girder 5 and the girder 7 and the floor base are fixed by nails 6 to the extent that the floor base does not come off. Therefore, the floor does not constitute the horizontal structure 2. Therefore, in order to increase the strength of the beam, it is necessary to reinforce it with an oblique member such as a flint beam.

The structure of the pipe pillar 8 and the brace 9 on the second floor is the same as the structure of the pipe pillar 8 and the brace 9 on the first floor. A hut floor is arranged on the upper part of the pipe pillar 8 on the second floor, and this portion is a horizontal structure surface 2 using a reinforcing plate 3 for a horizontal structure. This part is the ceiling on the second floor as well as the floor of the hut. The structure of the horizontal structure 2 is the same as the structure of the floor on the second floor, and is composed of horizontal members such as girders 5, small beams 7 and grand beams 16 and a reinforcing plate 3 for horizontal structure. 3 is firmly fixed to the horizontal member by a large number of nails 6.

In the conventional frame construction method, a plate material 12 as a ceiling on the second floor is hung from a hut beam. The plate material 12 is merely a partition and cannot support a vertical load. Further, the hut beams and the ceiling are fixed by nails 6 to the extent that the ceiling does not fall. Therefore, the ceiling does not constitute the horizontal structure 2. Therefore, in order to increase the strength of the beam, it is necessary to reinforce it with an oblique member such as a flint beam.

Generally, when building a hut in the conventional shaft assembly method, workers are forced to perform dangerous work on the hut beams because there is no floor at the bottom of the hut. When a hut is built on the upper part of the hut floor, it is possible to prevent a fall accident due to stepping off, or an accident in which a worker who is working on the floor directly below is injured by dropping tools or materials. In addition, it is possible to build a hut on the floor of the hut, and it is possible to work safely and efficiently.

A field board 11 is arranged at the upper part of the hut. A finishing material for the roof 19 such as a roof tile is arranged on the field board 11. When the roof 19 is generally constructed in the conventional frame construction method, the worker is forced to perform dangerous work on the hut or purlin. When the roof 19 is constructed on the upper part of the hut, there is a floor in the lower part of the hut, so a fall accident due to stepping off, or an accident in which tools, roofing materials, etc. are dropped and the worker working on the floor directly below is injured. Etc. can be prevented. In addition, the field board 11 and the roofing material can be temporarily placed on the floor of the hut, so that the work can be carried out safely and efficiently.

The configuration of columns, beams and the like will be described with reference to FIG. In addition, in FIG. 1 (b), the reinforcing plate 3 for the horizontal structure and the brace 9 and the like are excluded. The second floor and the beam surface of the hut have almost the same structure. For the first floor, the base 4 or the girder 5 surrounds the horizontal structure 2 and a plurality of large pulls 15 or girders 7 are inside. And the grandchildren 16 are orthogonal to each other to form a grid structure.

The composition of the grid-structured horizontal members in each horizontal structure 2 is made as uniform as possible. The dimensions of the base 4 and the large pull 15 are unified, and the configuration of the girder 5 and the girder 7 corresponds to the dimensions used for the largest open interior space 1 in the entire building, and the precut (pre-processed) member. To use. For the grandchild beam 16, a member having the minimum configuration can be used. Further, since the formation of the girder 5 and the girder 7 corresponds to the dimension used for the largest unit area in the entire building, it becomes possible to correspond to the length dimension of the pipe column 8. The tube column 8, use precut member width and length dimensions are unified. By using many members of the same size, it is possible to simplify the structure and significantly shorten the construction period, and to make a building with a well-balanced structure in which the center of rigidity and the center of weight of the entire building are aligned.

The configuration of the open interior space 1 will be described with reference to FIGS. 2 and 3. In this embodiment, the square small unit is 4.5 tatami mats or 8 tatami mats. FIG. 2A is a plan view of the first floor, and on the paper, the upper right is the entrance and the upper part of the central part is the atrium. That is, there are five such square small units, and the allowable stress is calculated as an open indoor space 1 of 22.5 tatami mats or 40 tatami mats, and the configuration of the horizontal member used for the horizontal structure 2 and the arrangement of the bearing wall. After considering, finally combine and design each grid.

2 (a) and 3 (a) are plan views of the first floor and the second floor, respectively, and in FIG. 2 (a), the central portion is a stairwell. Allowable stress degree calculation is performed for the open interior space 1 created on the second floor, the composition of the horizontal member used for the horizontal structure 2, the second floor outer wall 18 for bearing the load from the roof 19, and the roof 19 and the second floor portion. Consider and design the layout of the outer wall 17 on the first floor that bears the burden.

2 (b) and 3 (b) are elevation views, showing the appearance of the wooden building and the position of the open interior space 1. In this embodiment, the open interior space 1 on the first floor and the open interior space 1 on the second floor are configured as one open interior space 1 having the same shape on each floor in the entire building, so that an open interior space with free partitioning can be created. It is possible to maximize the effect of the construction method 200 of the building structure to be built.

The details of the configuration of the horizontal structure 2 will be described with reference to FIG. FIG. 4A is an exploded schematic view of the horizontal structure 2. The horizontal structure surface 2 is composed of a horizontal member and a reinforcing plate 3 for a horizontal structure surface. For example, in the horizontal lumber on the second floor of the two-layer horizontal structure 2, a plurality of small beams 7 are orthogonal to the girder 5 inward, and the grandchild beam 16 is orthogonal to the small beam 7. Construct a grid. A horizontal structure reinforcing plate 3 is nailed to each upper opening of the grid so as to cover the opening.

As shown in FIG. 4B, the horizontal structure reinforcing plate 3 has a stepped portion 301 at the peripheral edge, and by contacting the side surface 701 of the horizontal member, the opening is closely closed and the upper portion is closed. It is fixed by the nail 6. About 10 nails 6 are driven in per side. As a result, the horizontal member and the horizontal structure reinforcing plate 3 form the horizontal structure 2. Further, the horizontal structure reinforcing plate 3 can be made thicker than the conventionally used floor base plywood because the lower peripheral portion 301 abuts on the side surface 701 of the horizontal member, and the strength of the horizontal structure 2 can be ensured. Is possible.

Further, when the peripheral edge of the horizontal structure reinforcing plate 3 does not have the stepped portion 301, the distortion of the horizontal structure 2 due to an earthquake or the like can be prevented only by fixing with the nail 6, and sufficient strength cannot be maintained. .. However, when the peripheral edge has the stepped portion 301 and is always in contact with the side surface 701 of the horizontal member, the horizontal structure reinforcing plate 3 can be effective in preventing distortion, and the horizontal structure 2 can be obtained. It is possible to secure the strength of.

Further, as another configuration of the stepped portion 301, it is conceivable that the horizontal member has the stepped portion 301, but the place where the nail 6 is hit is narrowed, and the reinforcing plate 3 for the horizontal structure and the horizontal member are sufficiently fixed. I can't do it. Further, when the thickness of the horizontal structure reinforcing plate 3 is increased in order to increase the strength of the horizontal structure reinforcing plate 3, the stepped portion 301 of the horizontal member becomes elongated, and the cross-sectional defect of the horizontal member is lost. It will increase and the strength will be insufficient. Therefore, it is preferable that the horizontal structure reinforcing plate 3 has a stepped portion 301.

Further, by setting the beam surface of the hut to the horizontal structure 2, it is possible to work on the hut floor in the work of assembling the hut and the process of roofing the roof 19. In the conventional shaft assembly method, in general, in the work of building a hut or the process of roofing a roof 19, workers are forced to do dangerous work on the hut beams and purlins because there is no floor at the bottom of the hut. When there is a cabin floor with the horizontal structure strengthening plate 3, it is possible to work safely and efficiently on the cabin floor.

FIG. 5 is an arrangement configuration explanatory view showing an arrangement configuration of the horizontal structural reinforcement plate 3 in the construction method 200 of the building structure for creating an open interior space with free partition according to the present invention, and FIG. 5A is a diagram. A configuration in which the horizontal member is arranged on one side surface is shown, and FIG. 5B shows a configuration in which the horizontal member is arranged on both side surfaces. It is preferable to provide the heat insulating material 13 in the space area created by the difference in thickness between the horizontal member and the horizontal structure reinforcing plate. In addition, in the configuration of arranging on both sides as shown in FIG. 5B, the weight is increased, but the strength against the horizontal load is increased, and the earthquake resistance is superior.

FIG. 6 is a basic configuration explanatory view of the partition wall 101 that can be freely arranged according to the present invention, and FIG. 6A is composed of a drop groove 112 for the locking portion 111 to drop the vertical surface portion 122. FIG. 6B shows a state, and FIG. 6B shows a configuration in which the locking portion 111 has a stepped surface portion 113 in contact with the vertical surface portion 122 and is sandwiched by a holding plate.

An example is shown in which the screwing member 132 is used for the fixing member 130 in a sandwiching configuration. Hereinafter, each component will be described.

The wall member 110 is not particularly limited, such as a flat wooden material, a resin material, or a material having a heat insulating material 13 internally and a panel made of wood or the like adhered on both sides, and the rigidity required for partitioning the interior space is not particularly limited. Anything that has However, it is desirable that the thickness is at least close to or thicker than the width in the longitudinal direction of the connecting member 120. Further, since it can be used as a shelf, it is more desirable to have strength as a shelf board.

Since the locking portion 111 is associated with the wall member 110 and fixed to the floor member 140, the ceiling member 150, or another wall member 110, the shape is determined in relation to the connecting member 120, and the drop groove 112 or the stepped surface portion It has a shape of 113.

The drop groove 112 is a groove into which the vertical surface portion 122 of the connecting member 120 is fitted, and in a configuration provided above and below the wall member 110, a depth sufficient for inserting the vertical surface portion 122 is required so that the vertical surface portion 122 can be dropped. .. Further, when the width of the groove is too wide with respect to the thickness of the vertical surface, rattling occurs, and when the gap is too narrow, workability deteriorates. Therefore, it is desirable to provide an appropriate clearance.

The stepped surface portion 113 is a step provided for sandwiching the connecting member 120 between the wall member 110 and the holding plate 114 and connecting the connecting member 120 with the fixing member 130. An end portion is provided between the step and the holding plate 114 for the vertical surface portion 122.

The holding plate 114 is a plate-shaped member for sandwiching and fixing the connecting member 120 that is in contact with the stepped surface portion 113 with the stepped surface portion 113, and is a member that fills the insufficient thickness with the connecting member 120 that is in contact with the stepped surface portion 113. Is. Further, when the fixing member 130 serves as a receiving plate and the screwing member 132 is used for the fixing member 130, a thickness that can obtain a depth as a female screw is required.

The connecting member 120 is composed of a horizontal surface portion 121 having a substantially T-shaped cross section and a vertical surface portion 122 orthogonal to the horizontal surface portion 121, and has a wall-to-wall abutment, a corner portion of the wall, a floor member 140 and a wall member 110, and a ceiling member. It is a connecting member used at all joints such as 150 and a wall member 110, a pillar and a wall member 110, and the like. By making the width of the horizontal surface portion 121 as small as or smaller than the thickness of the wall member 110, it can be hidden from the outside after construction and the appearance is not impaired.

The horizontal plane portion 121 becomes a flat flat contact surface that comes into contact with the floor member 140, the ceiling member 150, the pillar, the wall member 110, and the like, and is fixed by the fixing member 130 in the connecting member fixing step A.

When the locking portion 111 of the wall member 110 is configured as a drop groove 112, the vertical surface portion 122 is a portion where the vertical surface portion 122 is dropped and receives the locking portion 111, and the locking portion 111 of the wall member 110 is a stepped surface portion. In the case of the configuration of 113, the vertical surface portion 122 is a contact surface that comes into contact with the sandwiching member 114.

The vertical surface portion fixing hole 123 is provided in the vertical surface portion 122 and is a hole through which the fixing member 130 is inserted. When the locking portion 111 of the wall member 110 is configured as a drop groove 112, the fixing member 130 is inserted. It is also provided on the wall member 110 on the opposite side of the wall member 110. When the locking portion 111 of the wall member 110 has the configuration of the stepped surface portion 113, the vertical surface portion fixing hole 123 is provided in the holding member 114 with a diameter that becomes a pilot hole for the female screw of the screwing member 132 from the beginning. It may be left, and it is not necessary to provide the screwing member 132 in the case of a tapping screw.

The horizontal surface portion fixing hole 124 is provided in the horizontal surface portion 121 and is a hole through which the fixing member 130 is inserted. The connecting member 120 is fixed to the floor member 140, the ceiling member 150, the wall member 110, or the like. It is a hole for fixing by.

The fixing member 130 is a member for connecting the connecting member 120 to the wall member 110, connecting the wall members 110 to each other, connecting the wall member 110 to the floor member 140, and the like, and fixing each of them. .. A member for joining such as a nail 6 or a rivet may be used, but as shown in FIGS. 6 (b) and 8 (b), a removable screwing member 132 such as a wood screw is preferable, and more preferably FIG. Push rivets 131 as shown in 6 (a) and 8 (a) are desirable.

The push rivet 131 is a fixing member 130 that can be fixed with one push as shown in FIGS. 6 (b) and 8 (b) and can be easily removed by squeezing the tip, and is generally used for an instrument panel or the like of an automobile. It is the same kind as the one that is often used.

The screwing member 132 means a member to be connected by screwing such as a bolt and a nut, but unlike a wood screw or a tapping screw, a nut is not required and a female screw is formed at the time of screwing. The configuration is simple. The drawings show an embodiment using countersunk screws, but the present invention is not limited to this, and as described above, a wide variety of screwing members 132 can be used.

The floor member 140 is intended to have strength for fixing the connecting member 120 by the fixing member 130, such as a floor base plate, a floor beam, and a joist, as well as a floor plate. In particular, in the present invention, two or more layers are horizontal structures. In a building constructed by the surface reinforcing plate 3, the horizontal structural reinforcing plate 3 also serves as a floor member 140. However, it is shown as a normal floor board in the drawing.

It is effective that the ceiling member 150 includes not only a ceiling plate but also a field edge or the like, and if possible, a beam or the like is also used. In a general suspended ceiling type, there is a problem in strength when a load is applied to the ceiling member 150, so it is desirable to lock the fixing member 130 to a material having a high bearing capacity such as a field edge or a beam. By fixing to the ceiling member 150, it is possible to obtain the merit of enabling free arrangement.

The horizontal structure reinforcing plate 3 is a horizontal plate-like member fixed by fitting a lattice set made of orthogonal horizontal members and the horizontal structure reinforcing plate 3, and the fitting is the horizontal. A stepped portion 301 is provided at the edge of the structural surface reinforcing plate 3, and the vertical surface of the stepped portion 301 and the side surface 701 of the horizontal member having a rectangular cross-sectional shape are brought into contact with each other and fitted to each other.
