Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a joist fixing device used to separate upper and lower floors in the framework of a 2x4 wooden building.

[Prior art] This type of fixing of floor joists involves providing a head joint on the upper frame of the frame of the load-bearing wall on the lower floor, and using this head joint as a reference, the floor joists are mated, and the floor joists are moved between the floor joists. While stoppers are provided, end joists are installed on the outside of these floor joists in a covering manner, and the subfloor and load-bearing walls of the upper floors are placed and fixed on top of these floor joists.

[Problem to be solved by the invention] This joist fixing device has excellent strength, but it always requires load-bearing walls for each floor, and for example, in a three-story building, there is always a load-bearing wall at the top and bottom. A load-bearing wall with three sections will be required, and in terms of supporting the load of the building, it is desirable to use a load-bearing wall with better strength and fewer sections. but,
In the above-mentioned joist fixing device using load-bearing walls for each floor, it is impossible to reduce the number of load-bearing walls.

The present invention was made in view of these problems, and its purpose is to separate the relationship between load-bearing walls and floors, divide floors at intermediate positions of load-bearing walls, and sufficiently increase the strength of the building blocks. The purpose is to provide a new secured joist fixing device.

Means for Solving Problem El] In view of the object L, the present invention provides a series of upper and lower studs, a base material horizontally interposed between the studs, and a base material placed on the base material. It also includes a floor joist material face-to-face nailed to the side surface of the stud, and a horizontal member placed on the base material and interposed in a tight fit between the floor joist material and the adjacent stud. This article relates to a characteristic joist fixing device and is its gist.

[Function] In the present invention, a base material is interposed at an intermediate position of an arbitrary height in a series of upper and lower studs, and this base material is used as a reference position to install a joist material.

At this time, the joist itself is surface-nailed to the studs to obtain fixing strength, and the horizontal members maintain their fixing strength.

In addition, the load on the joists is transmitted to a series of upper and lower studs, and the horizontal members also prevent deflection and twisting due to vertical loads that may occur in the studs, thereby ensuring the overall strength of the load-bearing wall.

[Example] Hereinafter, the present invention will be further explained with reference to drawings showing examples. In the figure, 1 is a joist fixing device according to the present invention, and the fixing device 1 is a joist fixing device 2 of a 2×4 building.・、Base material 3・
..., floor joist material 4..., and horizontal member 5... In this example, the studs 2... are pre-assembled at the factory etc. by the upper and lower frames 6,
7 are nailed together to form an integral structural frame, and a structural plywood 8 serving as the base for the outer wall is also prestrung on the surface side thereof to form an integral load-bearing wall panel 9.

In addition, this load-bearing wall panel 9 has the above-mentioned stud 2...
The upper and lower frames 6.7 are made of a structural material having a cross section of 2 inches x 4 inches (actual size: 38 m x 140 cm), and the structural plywood 8 is 12 mm thick.

In addition, the load-bearing wall panel 9 including the studs 2... has a vertically long rectangular front shape of 3636 mm x 1616 mm, and its height is approximately half of the total wall height of the three-story building in this example. The length is set. Two panels are arranged vertically, and a required number of panels are arranged horizontally to form a wall surface.

The spacing between the studs is 4041mm on a center-to-center basis, or only the studs at the left and right ends are arranged at this spacing on the basis of the outer surface. As a result, the load-bearing wall panel 9 has 1
Each sheet has four studs 2... In addition, the structural plywood 8 may be stretched by nailing, or the pitch may be set at 1 point relative to the peripheral edges of the plywood, that is, the upper and lower frames 6, 7, and the studs at the side ends.
It is about 00mm to 150m, and about 200mm to other studs inside the surface.

Then, the load-bearing wall panel 9 including the studs 2... is erected on the upper stand l1 on the cloth foundation 10 as shown in Fig. 1, and after the joists of the second floor are fixed by this device l, Furthermore, a top and bottom frame 6 that is raised up and faces the top and bottom of both,
In addition to nailing the 7 pieces together, the joists for the third floor were also fixed to create a three-story wall.

Here, as mentioned above, the height of the load-bearing wall panel 9 is approximately half of the total wall height of the three-story building in this example, so the height of the joint l2 of the upper and lower load-bearing wall panels 9, 9 is While the floor joist material 4.4 is located at the mid-height of the second floor, the fixed position of the floor joist material 4.4 is at each of the studs arranged in series above and below for each load-bearing wall panel 9.9 on both the second and third floors. It is set as the midway height of 2...

That is, Figure 1 and! As shown in Figure s3, the base material 3... of the joist fixing device l in this example is the same as the stud 2...
InX 6 inch standard structural material, interposed between each stud at an intermediate position between the upper and lower series of studs 2... and fixed by driving nails diagonally, and also from the surface of the structural plywood 8 of the load-bearing wall panel. It's nailed down.

On the other hand, the floor joist material 4... is a structural material having a standard cross section of 2jn x 8in, and its end is placed on the base material 3..., and the side surface of the stud 2... It is nailed (nail l3...).

Further, the horizontal members 5... are structural members having the same cross section as the floor joists, and are placed on the base materials 3...
A nail is inserted diagonally into the base material 3, the floor joist material 4, and the adjacent stud 2, which are interposed in a tight fit between the side surface of the floor joist material 4... and the side surface of the adjacent stud 2... -・It is fixed.

A floor board l4 is stretched over the floor joists 4 fixed in this way.

It should be noted that it is of course possible to fix such joists on the entire wall, or in the case of a three-story wooden building, as shown in Figure 2, it is possible to fix the joists on the entire wall. A load-bearing wall panel 30 having a height of approximately one-third of the total height of the wall surface is placed adjacent to the load-bearing wall panel 9. Structural plywood (strung in advance on the surface of the structural frame) is stacked in three layers.As a result, each load-bearing wall panel 9,
and 30... are arranged in a staggered manner to further improve the strength of the load-bearing wall especially against horizontal loads.

Here, the floor joists are fixed to the load-bearing wall panels 30 having a height of approximately one-third of the total height of the wall surface at the lower end of the stud of each load-bearing wall panel 30. In other words, the floor joists are placed on a lower frame fixed to the lower end of the stud and are nailed face-to-face to the side of the stud, while the horizontal members are also placed on the lower frame and attached to the floor joists and adjacent studs. They are tightly fitted in between.

Next, to explain the other end of the floor joist 4, in order to make the span longer in the wooden example, it is connected and extended using a joint device 15 inside the building as shown in Figure 3. The end of the right joist 4 is fixed to a stud by the present fixing device as described above.

Here, the above-mentioned joint device l5 shifts the centers of the left and right pair of floor joists 4, 4 connected on the internal load-bearing partition wall l6, which is the fulcrum, in the front-back direction, and overlaps them in the left-right direction. At the same time, a fodder l7 having the same thickness as the stud 2 is placed in the overlapping part of the left and right floor joists 4.4, and left and right floor joists 4, The ends of 4 are attached and nailed (13...).

By doing this, it is possible to cut the floor joists 4, 4, compared to conventional methods in which the ends of the left and right floor joists were brought into contact with each other, and a splint was attached to one side of both for nailing. The dimensions do not necessarily have to be exact, and even if the floor joists dry and shrink, there will be no shortage of hanging allowance to the fulcrum. In addition, in the figure, 18 is a horizontal member interposed tightly between the floor joists of this joint, 19 is the upper frame of the internal load-bearing partition wall, and 20
is the same vertical frame. 21 is also the partition wall base. Furthermore, since the feeder 17 has the same thickness as the stud 2, the other end of the extended floor joist on the right side in the drawing is nailed face-to-face to the back side of the stud.

In addition, 22 in the w4l diagram is the roof exterior material of this # building, 2
Reference numeral 3 denotes the gassho of the roof hut, 24 the gassho butt, 25 the roof joists, and 26 the floorboards stretched over the joists, so that the interior of the roof hut can be used for a living room or for storage.

Although not shown in the drawings, of course the studs are not made into panels in advance like in the wooden example, but instead are framed at the construction site by fixing the upper and lower frames to cover one wall width.The wall frame is erected and the joists are fixed using this fixing device. After this, other work such as laying the base of the outer wall may be done. Furthermore, it is also possible to use a single stud that runs the entire length of the wall. Other stud spacing, cross-sectional dimensions of base materials, floor joists, and horizontal members (for example, 2 in
in standard, 2 inX s in standard, 2 inX
8 inch standard, etc.) can be set variously depending on the required strength.

Contrary to this point, in carrying out the present invention, the specific shapes, structures, dimensions, materials, and numbers of studs, base materials, floor joists, horizontal members, etc. may be modified, unless they are contrary to the gist of the invention. , arrangement, and their relationship can be changed in various ways. [Effects of the Invention] Since the present invention is configured as described above, as described in the effect column, the relationship between load-bearing walls and floors can be separated and floors can be divided at intermediate positions of load-bearing walls, so that the number of floors can be reduced. This makes it possible to form a long, integrated load-bearing wall with a small number of sections, and the load-bearing strength of this load-bearing wall can be improved. In addition, the series of studs above and below the load-bearing wall are the base material,
As a result of the floor joists and horizontal members preventing bending and twisting at intermediate positions, the use of this device allows building floors to be formed into extremely rigid structures, just like stacked H-beams.

Furthermore, since the floor joists can be placed on the base material and nailed face-to-face to the side surfaces of the studs, on-site work is extremely simple, even though the floor joists are nailed at an intermediate position between a series of upper and lower studs.
