Description

[Detailed Description of the Invention] (Object of the Invention) The present invention relates to a wall foundation structure corresponding to a conventional frame-framed wooden building, and relates to a wall foundation structure that is compatible with a conventional frame-frame wooden building, and includes a column through-hole, a through-hole, a stud, This project aims to provide new metal fittings to realize a wall base structure made of several parts, and a new wall base structure using the metal fittings, instead of a structure in which braces are processed and assembled on-site. be.

(Prior art) Although influenced by the rise of two-by-four and other brefab wooden constructions, the applicant has already developed the Heisei era wooden construction method as one of the rationalization methods for wooden construction, which still remains very popular. We have already proposed the invention in Patent Application No. 216866.

Even though it is a conventional construction method, it is important to rationalize as much as possible for the parts that do not particularly require handmade value. It is based on the recognition that this is a factor that brings out the substantial goodness of wooden buildings, and as a feature that should be rationalized, we focused on the features between the pillars, that is, the wall base structure, and developed and completed it. The basic structure is that horizontal members with a length equal to the internal dimension between the columns minus the dimension for the space for arranging the left and right joint fittings are arranged vertically in parallel at an interval corresponding to the through-forming interval. In addition, each of these horizontal members becomes a frame member with both ends protruding left and right, and either a thin plywood board or a vertical member corresponding to a stud, or a combination of both are used on both the front and back sides. By integrating it, it becomes a ready-made wall base panel, and the projecting portions at both ends of the cross member of the wall base panel are arranged between the columns so that the center line of the plate thickness coincides with the column center, and The pillars assembled in the construction of a wooden building with next axis are connected with joint fittings with a structure that can be combined and dimensionally adjusted, and these can be used as a wall base to create a true wall finish or a large wall finish as appropriate. It was intended to be the wall base structure of a frame-framed wooden building.

On the other hand, the present invention is a wall base structure for a frame wooden building completed in the process of further rationalizing the above-mentioned invention that had already been proposed, and in particular, new technical aspects were introduced regarding the joint metal part in the proposed invention. It was realized by incorporating ideas, and its structure is as detailed below.

(Structure of the Invention) As clearly understood from several representative examples of the present invention shown in the drawings, the present invention relates to an extruded dowel metal fitting and a wall base structure of a frame wooden building using the same. First, the basic structure of the protruding dowel metal fitting will be explained as follows.

That is, one end of the rod-shaped material is the protruding fixing part 11 that can be assembled into the left and right or upper and lower opposing sides 24.24 or 25.25 of the wall base material 2 so as to move forward and backward, and the other end is the frame assembly. It is formed in a dowel portion 12 that can fit into a dowel hole or dowel edge 31 or 41 formed on the inner slope of the material 3 or 4, and the dowel portion 12 and the pushing-out operation portion 1
This is a protruding dowel fitting 1 in which a collar part 13 is disposed between the dowel part 1 and the dowel part 1, and a protruding operating part 14 for relatively advancing and retracting the dowel part 12 is formed at an appropriate position.

The rod-shaped material forming the metal fitting 1 has a length and thickness that can be incorporated into either the left or right or top and bottom sides of the wall base material 2 and exhibit sufficient integrated strength. Although it is made of a metal material such as steel, it can also be made of a strong plastic material or other material if necessary.

Hereinafter, the specific structure of this metal fitting 1 will be explained using some representative examples shown in the drawings.

(Example 1) First, an explanation will be given of an example shown in an enlarged cross-sectional view of the main part shown in FIG. 3, which also shows the mode of use. It is formed in a screw structure that allows direct penetration from either the left or right or top and bottom sides 24', 24, or 25.
It has a structure in which the dowel portion 12 is moved forward and backward relative to the dowel portion 12 so that the dowel portion 12 is relatively pushed out.

The screw structure of the protruding fixing part 11 is a coach screw type, and the screw structure is formed in a pilot hole 2 formed in advance on the side surface 24 of the wall base material.
It is forcibly inserted into 6 and becomes a body.

The protruding operation part 14 is formed in series with the proximal end of the protruding fixing part 11, and has a configuration for rotating the protruding fixing part 11, for example, is formed in the cross section of a gear 14a as shown in FIG. 4a. gears, hexagonal (polygonal) as shown in the same figure, gears with cross holes 14b as shown in figure C, etc. In the case of gear 14a, the cross section of the gear 14a is equipped with a special power tool or other gear. By engaging or fitting a tool, a wrench for type B, and a screwdriver or other thin rod for type C, and operating them in the forward and reverse directions, the protruding fixing part 11 is attached to the side surface of the wall base material 2. The dowel portion 12 can be moved forward and backward from 24, and the dowel portion 12 can be relatively pushed out as it moves forward and backward.

In this example, the protruding operation part 11 is formed at the base of the threaded structure (on the side where the dowel part 12 is formed), but it can also be formed at the tip of the threaded structure as shown in FIG. This can be adopted in a structure in which the wall base material 2 consists only of vertical frames 21, 21 and horizontal frames 22, 22, or in a structure in which a face plate 23 is pasted on only one side.

Note that the end of the protruding operation part 14 opposite to the end continuous to the protruding fixing part 11, the end continuous to the dowel part 12 (in the embodiment shown in FIG. 8, the screw structure of the protruding fixing part 11) base)
is formed as a stepped portion for positioning the flange portion 13.

The flange 13 is for stabilizing the supporting strength of the metal fitting 1 to the frame member 3 (or 4), and may be a mere washer-like member as shown in FIG. 3, or as shown in FIG. a
Like the one of spikes 13a, 13a,...
・Or, as shown in the figure, biting ears 13b, 13b, etc. are formed, and the state of support to the frame member 3 (or 4) is improved. It is possible to have a structure that makes it more stable.

It goes without saying that the structure of the collar portion 13 can be selectively adopted as appropriate in each of the following embodiments.

(Example 2) The metal fitting 1 of the present invention, represented by the structure shown in the enlarged vertical sectional view of the main part in FIG. side 24 or 2
5, and a bolt/nut portion 11b formed inside the fixing portion 11a.
The flange part 13 and the dowel part 12 are connected to the nut of the bolt/nut part 11b, and the dowel part 12 relatively protrudes as the nut, which also serves as a protrusion operation part, advances and retreats. It is what it is.

The protruding fixing part 11 having this structure is integrated by applying an adhesive and forcibly driving it into a tight fitting hole previously drilled in the wall base material 2.

Note that the bolt/nut part 11b also serves as the protruding operation part.
The nut may be a so-called hexagonal back-through nut, or may have any of the structures shown in FIG. 4 above.

(Example 3) The metal fitting 1 in the following example has the structure shown in the enlarged vertical cross-sectional view of the main part in FIG. a male screw portion 11c that is incorporated into and fixed to either one of the pair of side surfaces 24 or 25;
It consists of a male screw part lid that is screwed into the male screw part 11c, and the protruding operation part 14 is integrated on the screwed part base side of the male screw part lid, and the collar part 13 and the dowel part 12 are connected, This is a protruding tenon metal fitting 1 in which the dowel portion 12 relatively protrudes as the male screw portion 11d moves forward and backward.

The male screw portion 11c of the protruding fixing portion 11 in this example is fixed by applying adhesive and driving it into a tight fitting hole previously drilled in the side surface 24 (or 25) of the wall base material 2. Therefore, it does not become a part of the wall base material 2 and is removed, and the male screw portion lid side can be assembled at the wall base formation site.

The protruding dowel fitting 1 of the present invention, represented by the structures of the embodiments shown in the above three examples, may employ various other known protruding structures, the structure of the flange 13, etc. Alternatively, it goes without saying that it is also possible to fix the protruding fixing portion 11 of the protruding dowel metal fitting 1 on the 4 side.

In the drawings showing each embodiment, numeral 3 indicates a column, numeral 4 indicates a horizontal member such as a foundation or beam, and numerals 31 and 41 indicate a dowel hole or a dowel groove formed therein, respectively.

Next, the wall base structure of a framework wooden building formed using the protruding dowel metal fittings 1 having such a configuration will be explained.
The results are as follows.

(Other related inventions) As is clear from the partially omitted elevation view in Figure 1 and the typical S structure shown in the enlarged horizontal sectional view of the main part in Figure 2, this invention The wall base structure of the invention consists of a pair of opposing sides 2 on either the left or right side or the top and bottom of the wall base material 2.
4.24 or 25.25, the protruding dowel fittings 1, 1. The wall base reference member, which is made up of a wall base reference member that is movably incorporated in the wall base, is regulated to a width smaller than the internal dimension between opposing frame members 3.3 or 4 and 4 in the part where the wall base is to be formed. A large number of these pre-fabricated wall base reference members are formed with the protruding dowel fittings 1, 1.・・・

2 into the corresponding dowel hole or dowel groove 31 or 41
These protruding dowel metal fittings 1 are used as bridge construction materials, and the existing frame members 3.3 or 4.4 are assembled one after another in the manner of a conventional frame wooden building. This is a wall base structure for a framework wooden building in which wall base reference members are integrated and can be used as a wall base to finish a solid wall or a large wall as appropriate.

The wall base material 2 of the existing wall base reference member is the vertical frame 21.21
．． . . . and horizontal frames 22, 22 . In addition to a panel-like structure in which a face plate 23 such as a plywood board is pasted on both or one side of a frame (frame body incorporating diagonal members 24 as shown in the example shown in FIG. It is also possible to use a so-called shanty village material that is about the same size as the original.

These wall base reference members may be arranged horizontally if the pillars 3, 3 are used as frame members, as shown in the partially omitted elevation view of Fig. 1, or they may be arranged horizontally as shown in Fig. 12. As in the example, when horizontal members 4.4 such as foundations, beams, and girders are used as framework members, they are arranged vertically, and the protruding dowel fittings 1°1, . . . of this invention are , is tied to at least one of the side surfaces 24.24 and 25.25 of the wall base material 2, which is the supported frame member 3.3 or 4.4 side.

That is, in the case of a wall base reference member in which the protruding dowel fittings 1, 1°, etc. of the present invention are incorporated only on one side surface 24 or 25 of the wall base material 2, the remaining side surface On the 24 or 25 side, there is a dowel portion 52 as shown in the enlarged vertical cross-sectional views of the main parts in FIGS. 9 and 10.
The flange 5 is designed so that it does not protrude at all, and can simply accommodate the depth of the dowel hole or dowel arm 31 or 41.

... will be driven in and fixed.

The size of the wall base reference member is 24°24 or 25.
25 is combined with protruding dowel metal fittings 1゜1, . For example, if the framework member is made up of columns 3 and 3 as shown in Figure 1, the so-called internal size is calculated by subtracting the cross-sectional dimension of column 3 from the inter-column dimension. It should be of medium size, slightly smaller than the normal size, or
Or dowel hole or dowel eraser 31 or 41
The size is within the width dimension plus the depth of one hole.

Note that it is of course possible to fill and combine the hollow portion of the wall base material 2 with a heat insulating material or other insulating material in advance at a factory.

(Operation and Effect) The protruding dowel fitting 1 of the present invention having the above-described configuration
is a pre-formed crystallized wall base material that is built into either the left or right or top and bottom sides 24.24 or 25°25 of the wall base material 2, and is manufactured in a factory. A large number of reference members are formed in advance,
After the framework wooden building constructed using conventional construction methods is delivered to the site, holes are drilled as specified on the inner slope of the framework member 3.3 or 4.4 at the location where the wall base is to be formed. Dowel holes or dowel erasers 31.31. ...or 41, 41. . . . Attach the protruding dowel fittings 1, 1 of each wall base reference member. The protruding dowel fittings 1.1゜ are built into either side 24 or 25, roughly corresponding to... (However, the protruding dowel fittings 1,

Similarly, the dowel portions 12, 12 .・・・・・・
However, the final adjustment is left as is.

After fitting all the necessary wall base reference members between the frame members 3.3 or 4.4, make final adjustments taking into account the overall posture and the condition of the gaps, etc., using the respective protruding dowel fittings 1. ,1. . . . protruding operation parts 14, 14.・
By operating and implementing ..., the wall base structure will be completed.

If you want to use this wall base structure to create a solid wall finish, as shown in the enlarged horizontal sectional view of the main part in Figure 2,
Apply Laspode or other suitable base material 6 to the surface of the wall base member 2, and finish the wall finish 7 using the dust-treated pillar 3 as a ruler, or, as shown in the same figure, apply the base material 6 to the surface opposite to the painted wall side. As shown, in the case of finishing a large wall, after attaching the vertical members 8 corresponding to the studs (however, the vertical members 8 are also divided into the size of the wall base material and prepared in advance at the factory production stage). It is also possible to attach the divided vertical members 8 to each wall base member 2, 2, etc. and use them as wall base reference members, in which case these wall base members with vertical members Immediately after the standard members are delivered to the site and assembled (immediately), the decorative panels are directly pasted up, but the base material to create a large wall finish is attached as needed and the finished work is done as a cross-thickness, etc.

In this way, anyone can quickly and reliably create features on the wall base that are completely hidden inside the wall after it has been finished, without requiring particularly skilled techniques. Because of this, it is possible to streamline the construction without affecting the handmade quality of frame-framed wooden buildings using conventional construction methods, and as the shortage of craftsmen is predicted to become even more serious in the future, It can be said that it can have a beneficial effect.

In particular, when the protruding dowel metal fitting 1 is such that the protruding fixing portion 11 can be directly screwed into the side surface of the wall base material 2, as shown in Embodiment 1, The structure of the metal fittings is simple and can be provided at low cost, and although the m-shaped structure shown in Embodiment 2 or 3 has a slightly more complicated structure than the former, it is easy to operate the protrusion. In addition to being excellent in this, the wall base material 2 can be used with peace of mind even when there are concerns about the side structural strength of the wall base material 2.

The wall base structure of the present invention formed using these economical and easy-to-operate protruding dowel fittings 1 is naturally extremely economically advantageous, and has structural features such as Base reference member is frame member 3, 3 or 4
, 4 are independently supported, so even if it is necessary to remove them for some reason, they can be removed individually. The installation is stable, and even if some vibrational force is applied to the building, the metal fittings will not make any noise. Furthermore, each wall base reference member must be set at 3° for the frame member. It has many advantages, such as realizing a structure in which the parts 3 or 4 are connected in a strut-like manner, and can work advantageously on the deformation and machinability of the shaft layer structure.

As seen above, the protruding dowel metal fittings of this invention and the wall base structure of frame-framed wooden buildings using them have no effect on the characteristics of frame-framed wooden buildings, which has been an excellent architectural style since ancient times in Japan. It makes it possible to rationalize construction work without any problems, and is more advantageous in terms of economy, operability, structure, etc. compared to the previous ones, and it is better than Japan's traditional framework. This invention can be an extremely useful invention that will be indispensable for the continued use of wooden architecture for a long time.
