Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improved wooden residential building. Wooden buildings include the framework construction method traditionally used in Japan and the 4th century wooden construction developed in North America.
Both frame wall construction methods, which were rapidly introduced in Japan following the Ministry of Construction's notification dated July 27, 1999, have become mainstream.

However, these conventional buildings have drawbacks in terms of structure and construction as described below. The present invention overcomes the drawbacks of both of the above-mentioned buildings, and provides remarkable effects not found in either of them.

In the conventional framework construction method, the framework is formed by measuring and cutting the four corner pillars, girders, joists, etc. at the construction site, and then the roof is assembled first. The construction method used is to then work on the floors and walls of each floor. After assembling the frame and roof, work must be temporarily stopped and allowed to dry for about two weeks to adjust dimensional accuracy. Therefore, on-site work has to be prolonged. In addition, it is designed to withstand horizontal and vertical loads using only the frame structure, which includes columns, horizontal members, braces, and flint materials. Therefore, thicker lumber and lumber without defects are required, and problems arise as wood resources become rarer. That is, it has the above-mentioned drawbacks in terms of man-hours and materials, and also causes an increase in construction costs. On the other hand, the framework structure described above does not exist in buildings using the frame wall construction method, which is one of the conventional examples, and the construction method is called the platform construction method, in which the first floor frame is first built on the foundation, and the structure is Next, use this first floor floor assembly as a work platform (platform) and construct the floor wall framework, and then erect it.
Furthermore, a second floor frame is built on top of this first floor wall frame, and structural plywood etc. are also nailed down. Next, the second floor frame is erected using this second floor frame as a work platform (plant form), and the upper floor frame is built in the same way. Build the floors, ceiling framework, and roof framework. All of the structural members are joined by nailing. In terms of structural mechanics, the box-shaped structure made up of floor and wall assemblies is designed to withstand horizontal and vertical loads. Therefore, the number of man-hours on site is reduced compared to the frame construction method building 1c, but there is a restriction that construction must be carried out sequentially from the lower floor to the upper floor, and there is a limit to the shortening of the construction period. Structurally, each floor is an independent box, which is simply connected by nails. The horizontal load is transmitted from the floor assembly to the wall assembly on the lower floor, which is connected by nailing, and the vertical load is transmitted from the wall assembly to the floor assembly on the lower floor, and finally to the ground. Therefore, although the structure of each floor is connected by nailing, in other words, even though the sections are connected by nailing, there are gaps in the joints, which eliminates concerns about the structure itself, and even the nailing work itself. Can not. In particular, the work of designing and aligning the corner pillars, where stress is concentrated, is complicated. In addition, unlike the frame construction method, there is no axis that serves as a coordinate axis, which poses problems in construction, and this causes errors in the dimensional accuracy of the entire building not only during construction but also after completion.

On the other hand, in the present invention, a p-shaft is constructed of a foundation, a sill, an eave girder, and a pipe column (through-pillars, if necessary), and a structural panel is further attached to this frame by nailing, and the floor assembly is assembled. In addition, the entire wall structure is constructed, and this is also a strength member as a surface. It becomes. Therefore, it has excellent advantages in terms of structural design. In other words, it has a box-shaped structure, but since the corner pillars at the four corners, the middle pipe pillar, the foundation, the girder, and the eave girder exist as a frame, the flow of stress caused by horizontal and vertical loads is carried out in the frame in the Tosa style. Additionally, the stress flows to the floor and wall assemblies, and both of these stabilize the stress distribution throughout the building.

It also has excellent earthquake and wind resistance. Furthermore, the construction method allows the framework to be constructed before the floor and wall assemblies.
After the framework is completed, the floor assembly and second floor assembly can be assembled, and the walls of both floors can be constructed at the same time, and the shortest construction order can be selected as appropriate. Therefore, unlike conventional framework wall construction buildings, the order of construction is not restricted, and in conventional framework construction construction, not only 11ξII construction but also cutting of crushed materials and receiving materials can be done on-site. However, with the present invention, these on-site operations can be almost eliminated, and the construction period can be greatly shortened. Furthermore,
Because it is artificially dried in advance at the factory as necessary (moisture content 15
~25%) The strength of the members will increase, and the dimensional accuracy of the entire building will also be extremely high. In traditional frame construction method buildings,
Dimensional accuracy is determined by the framework, that is, the three-dimensional intersection of the axes, but due to its weight, dryness of the timber, etc., even if the roof assembly diameter framework is dried, there is a problem in dimensional accuracy. Similarly, in framed wall T-method buildings, there is no frame as a coordinate axis, and the construction order is restricted from lower floors to upper floors, which gradually supports the building load and its weight changes. , the error in dimensional accuracy at the time of completion increases.

On the other hand, in the building of the present invention, there are relatively few restrictions on the frame as the coordinate axis and the construction order, and dimensional accuracy can be maintained by the floor and wall assemblies, so the dimensional accuracy is extremely high upon completion of the building and during the period of use. It has become.

Examples of the present invention will be described below. Figure 1 shows details of the cloth foundation and one-story floor assembly of the building according to the invention, Figure 2 shows details of the 42-story floor assembly and roof assembly, and Figure 23 shows the framework of one of the conventional examples for comparison. Figure 1 shows details of the first-floor floor assembly of a building using the wall construction method, as well as details of the second-floor floor assembly and roof assembly, and Figure 5 (d) shows the second-floor wall framework of the building according to the present invention.

As shown in Figure 1, reinforced concrete cloth foundation 1. To (

On the other hand, tube column 10. It is connected to the base 6 by a joint (post) 7, a lower frame 8° for wall framing is provided adjacent to the pipe post, and an anchor bolt 2. is the lower frame 8. Structural surface material 5], foundation 6. and reinforced concrete cloth foundation 1, all of which are firmly connected to each other. Therefore, a horizontal structure consists of a reinforced concrete cloth foundation 1, a quadrilateral framework constituted by a foundation (), a foundation 6, and a floor joist 5. The structure is determined by the flooring made up of both the structural panel 1) nailed to the floor. Figure 12 shows the details of the second-story floor assembly and roof assembly. The trunk difference 18. which constitutes the quadrilateral framework of the two-story floor assembly. and a joist bracket 15. 2nd floor floor joist 14.
will be installed. and said floor joist [4, structural panel 1 on top]
6. is stretched.

Therefore, the horizontal structure is the same as the first floor, with a trunk difference of 1:31 and a floor joist of 14. and a quadrilateral frame consisting of a flint beam (not shown), and a girder 13. and floor joists 14. Structural facing plate nailed to 16. The structure is determined by the floor assembly made up of both. Also, the roof frame has 200 eave girders and 21 roof beams. and flint beams (however,

The eave girder 20. A second-story pipe column 18 is connected to the pipe column 18 by a joint. Furthermore, on top of these, sheathing boards or structural surfaces vJ23. 22. installed via. Therefore, in the case of a horizontal (roof) surface, the structure is determined by the quadrilateral framework, or if a structural panel is used for the roof 23, the structure is determined by the framework and roof assembly.

As mentioned above, the structure of the horizontal structure is determined by the framework and the floor assembly made of structural surface materials for both the two-story floor assembly and the roof assembly, and the structure of the roof assembly is determined by the framework and the floor assembly. On the other hand, in a conventional frame-wall construction building, there is no framework, and only the floor surface made of the framework and structural panels installed on it determines the horizontal structure of the structure. .

That is, the figure 3 shows the detail of the first floor of the building, and the base 28 made of frame material can be installed on the cloth foundation 29 degrees. and base 28. Side joists 27, floor joists 24. are attached, and a structural panel 25° is installed on the upper surface of both members by nailing as well. However, since it is made of frame material, holes for anchor bolts are provided for side joists 27, floor joists 24. It is not possible to set up
It is difficult to fix the floor assembly to the foundation 289, cloth foundation 2) with anchor bolts. Therefore, the structure of the horizontal construction surface is determined by the floor surface made of joists and structural panels. Figure 4 shows the details of the second floor truss and roof truss, but the first floor stanod 81 is the frame material. and upper frame 32
．． A framework for the story wall is constructed and structural facings (not shown) are nailed to the framework.

Therefore, the upper frame 32. Head ties to strengthen comrades 33. is installed, and the second floor side joist 86. is installed on the Murakami surface. and anti-fall35. Second floor floor joists narrowed by 34
．． Both are installed by nailing. Then, a structural panel material 37 is applied to the upper surfaces of these joists. Therefore, like the first floor, there is no framework on the horizontal structure of the second floor, and the structure is determined only by the floor surface from the frame joists and structural panels. Furthermore, the roof frame has a top frame of 421 and a headboard of 43. A ceiling joist 44 is provided above, and a structural panel 46. Gataru tree 45. installed via. Therefore, the structure of the horizontal (roof) surface is determined by the roof surface made of structural surface materials. Third,
As is clear from Fig. 4, it has a surface structure in which the frame Mi is made up of frame materials and all the structural panels are nailed to this, and there is no framework like in the building of the present invention. Also, the connection method is only by nailing, and there is no connection by a shikiguchi.

Next, a wall structure, which is a vertical structure, of an embodiment of a building according to the present invention will be explained. FIG. 5 is a frame diagram of one of the -1 second floor wall structures (however, the structural panels attached thereto are not shown), and the other streets are basically the same. The corner pillars consist of 51.51° pillars that penetrate through the second floor. However, if necessary reinforcement is performed, the pipe columns on each floor may be connected via a trunk gap. The upper end surface is the eave girder 2U, the boundary between the -1 and second floors is the girder difference 130, and the lower end surface is the foundation 6. Further, both sides of the opening (window) 54 are constituted by tube columns 55° 55, and furthermore, the tube columns 55 and 55 are located between the through column 5L and the tube column 55:
55. A half-post 56 is appropriately installed in the middle. Furthermore, several studs 52 and 53 are installed as appropriate. Structural panels are installed on the exposed faces of these pillars and studs by nailing, except for the openings. Therefore, the vertical structural surface includes the pillars 511, the eave beams 201, the girder difference 138, the foundation 6, the pipe pillars 55, . A framework constituted by these members and studs 52, 53. The structure is determined by the wall structure made up of both the structural panels installed on the facing surface.

On the other hand, in a conventional example of a building using the frame wall construction method,
, as in Figure 4, there is no axis +n in the wall structure, and the structure is determined only by the framework made of wall frame materials and the wall surface made of structural panel materials attached to this facing surface. .

As is clear from the above description of the embodiments of the present invention, the present invention is a building constructed by attaching structural paneling to a frame structure to form a floor assembly and a wall assembly.
