BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a blade bolt used for connecting a column to a horizontal member such as a beam or a base in the construction of a building mainly using a wooden structural material.

[0002]

2. Description of the Related Art In a building such as a house, a feather board bolt has been known as a connecting member for building used when connecting a horizontal member such as a beam or a base to a pillar. The most common type of blade bolt is one in which the root of a conventional bolt is fixed to one end on the surface of a flat plate with a hole for mounting by arc welding, and the hole for mounting is drilled. In some cases, the flat metal plate is bent at both ends in such a manner as to be folded from both sides in the width direction toward the center, and is fixed to the bent portion by arc welding with the root of a bolt interposed therebetween.

[0003] Specifically, the method of using the blade bolt is such that the flat plate portion side is aligned with a horizontal member, and a mounting hole provided in the flat plate portion and a bolt insertion hole formed in the horizontal member are inserted. A bolt is passed through the through hole, a nut is attached to the tip end of the bolt, and the flat plate portion is fixed to the cross member. On the other hand, the bolt screw side of the blade bolt is connected to the column to which the cross member is connected. It is inserted into a through hole for inserting a bolt formed in a pillar and a nut is attached to the tip to fasten the pillar, and is used for the purpose of assisting the connection between the horizontal member and the pillar.

[0004]

However, in the above-mentioned conventional blade plate bolt, if the column is too thick, for example, with respect to the length of the blade bolt, the tip of the bolt is buried in the through hole of the column. And the nut cannot be installed. On the other hand, it is also possible to provide a counterbore on the column so that the nut can be attached, but the depth of this counterbore is also limited by the thickness of the column, and each time a column of different thickness is used. The pillars must be dug properly at the appropriate depth. Also, the position where the flat plate portion is fixed to the horizontal member can be shifted to the column side so that the nut can be attached to the tip of the bolt, but in this case, each time a column of different thickness is used, the horizontal member The through-hole must be provided at an appropriate position according to the thickness of the column, and it takes time to process the building material.

If the thickness of the column is too small, the tip of the bolt protrudes more than necessary from the surface of the column. In this case, if the screw of the bolt is too short, the column cannot be tightened to the bolt even if the nut is mounted. On the other hand, the bolt screw can be formed long so that the column can be tightened to the bolt by installing a nut.However, in terms of mechanical strength, the screw should be as short as possible. However, suitable screw lengths will vary with each use of columns of different thicknesses.

[0006] If the tip of the bolt projects from the surface of the pillar, this portion hinders work and is dangerous.
It takes time and effort to delete this protruding part.
On the other hand, the position where the flat plate portion is fixed to the horizontal member can be kept away from the column so that the tip of the bolt does not protrude from the surface of the column. The through hole of the frame material must be provided at an appropriate position according to the thickness of the pillar, and it takes time to process the building material.

[0007] As described above, in any case, one type of wing plate bolt having a dimensional specification, a cross member having a through hole for inserting a bolt at a predetermined position, and no counterboring or a constant It was not possible to connect a pillar with a dugout at the depth.

[0008]

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and is a type of wing plate bolt having one dimension specification.
A horizontal member with a through hole for bolt insertion at a certain point,
It is an object of the present invention to provide a feather board bolt capable of connecting to a pillar having no sitting or having a fixed depth at a certain depth. That is, the blade bolt of the present invention is formed by fixing the other end of the bolt having a helical screw at one end thereof to the top of the raised portion of the fastening member which is bent near the end of the flat plate and raised. The member is provided with two holes of substantially the same size and shape along the longitudinal direction of the bolt.

[0009] In the above-mentioned blade plate bolt, it is preferable that the hole provided in the fastening member has a substantially regular polygonal shape.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in detail with reference to the drawings. The drawings show one embodiment of the present invention, FIG. 1 is a partially omitted perspective view showing an example of a wing plate bolt of the present invention, FIG. 2 is a front view of the wing plate bolt of the present invention, FIG. 3 is a plan view, and FIG. FIG. 5 is a sectional view taken along line AA of FIG.

As shown in FIGS. 1 to 5, for example, as shown in FIGS. 1 to 5, a blade bolt 1 of the present invention is formed by connecting a metal bolt 3 having a helical screw 2 formed at one end thereof to a predetermined length. In the vicinity of the end of the flat plate, both ends in the width direction are bent so as to be narrowed toward the center, the center is raised in a semi-cylindrical shape, and two protruding portions are formed on the surface to form joints 4, 4. The fixing member 5 is fixed to the joining portions 4 and 4 by spot welding. The fixing member 5 has two substantially square holes 6 (6) of substantially the same size along the axial direction of the bolt 3.
1, 62) are provided at predetermined intervals. The hole 6
Are provided with some R at the corners. Incidentally, reference numeral 61 denotes a hole far from the bolt 3, and 62 denotes a hole near the bolt 3.

As for the length of the bolt 3 from the position 7 corresponding to the end of the fastening member 5 to the tip 8 on the side of the helical screw 2, a thin column of usually 100 mm square is most often used.
As a whole, those having a size of 105 mm square are most often used, so that the size is preferably 100 mm or more, and particularly preferably 105 mm or more.

The hole 61 is a hole used for fixing to a horizontal member when a thick pillar is used, and the hole 62 is a hole used for using a thin pillar. Therefore, from the center of the hole 61 to the hole 6
The length up to the center of 2 is preferably equal to or greater than the length corresponding to the difference in thickness between the thick and thin columns. Particularly preferably, the difference between the thickness of the thick column and the thickness of the narrow column is set so that the bolt heads do not touch each other and a wrench can be used in case that the bolt is inserted into both of the two holes 61 and 62. Or the maximum width of the bolt inserted into the hole 6 (61, 62), and the width of the edge of the wrench (the thickness of the part holding the bolt head) of a size that can tighten the bolt. The length is slightly longer than the longer one. That is, for example, an a (mm) square pillar is used as a thick pillar, and a b (mm) square pillar is used as a thin pillar,
The maximum diameter of the bolt is (cmm) and the width of the wrench edge is d
(Mm), the length L from the center of the hole 61 to the center of the hole 62 is represented by [ab] (mm) or [c + d].
(Mm) is preferably slightly longer than the longer one.

When formed as described above, as shown in FIG. 6, when one of the thick pillars is used, it is fixed to the horizontal member by using the hole 61 of the blade bolt 1, and the bolt 3 If the tip of the column could not be projected from the surface of the column and the column could be connected to the horizontal member using the blade bolt 1 without providing a deep counterbore (FIG. (A)). On the other hand, when a thin column is used, if it is fixed to the horizontal member using the hole 62 of the blade bolt 1, the position of the through hole for inserting the bolt of the horizontal member is the same, and the tip of the bolt 3 is The depth of the seating can be made exactly the same as that of the thicker pillar without protruding from the surface and without providing a deeper seating on the pillar. It is possible to connect a thin column and a horizontal member using the same blade bolt 1 as that of the above-mentioned one. (B)).

The above-mentioned thick pillar is usually 120 mm
Corners are most often used, and thin pillars are 10
A bolt with a maximum head diameter of about 20 mm and a wrench with an edge width of 2 mm is most commonly used.
Since an impact wrench of about 3 mm or a wrench having a width of about 5 mm is used, the length from the center of the hole 61 to the center of the hole 62 is [120-100] mm or [20+
5] 30 which is slightly longer than the larger 25 mm of 25 mm
mm is preferable. Of course, it is not limited to this length.

In the present invention, the shape of the hole 6 is not limited to a substantially square shape, but may be any shape, but is preferably a substantially regular polygon, particularly a substantially square shape. Note that the substantially regular polygon includes a perfect regular polygon. The meaning of the hole 6 being a substantially regular polygon means that the hole 6 has a role as a wrench. From this fact, the most significant polygon other than square is the regular hexagonal shape of the bolt head, especially the square root of the flat head bolt, and the size of the hole is smaller than that of the square root. Matched dimensions.

Further, in the present invention, the material of the blade bolt 1 may be a metal, and in particular, various steel materials having sufficiently high strength and being versatile and inexpensive as structural members for construction are preferable. Further, the wing plate bolt 1 can be subjected to a rust prevention treatment as required. A conventionally known method can be used for the rust prevention treatment.

In the present invention, the fastening member 5 has a shape in which the vicinity of the end portion is curved in the width direction, the central portion is raised, and two joining portions projecting from the upper surface of the top of the raised portion are provided. As means of, for example, by press molding or bending
In the vicinity of the end of the metal flat plate, the both ends in the width direction are bent so as to squeeze toward the center, the center is raised in a semi-cylindrical shape, and the top of the raised portion is intermittently recessed. In addition to the method in which the part excluding the bent part is used as a joint, a method by casting using a mold can also be used.

In the present invention, the means for joining the bolt 3 to the fastening member 5 is not limited to the spot welding described above, but may be arc welding. In this case, it is not necessary to provide the joint 4 on the upper surface of the fastening member 5.

Next, referring to FIG. 6, the blade bolt 1 of the present invention will be described.
The means for connecting the column and the horizontal member by using will be described. In using the vane plate bolt 1 of the present invention, for example, as shown in the figure, a through hole 9 for bolt insertion and a counterbore 10 at an end of the through hole are provided at a position slightly adjusted to a position where the vane plate bolt 1 is provided. The pillar 11 provided and the bolt 1
At the portion where the cross member 13 provided with the through hole 12 for bolt insertion at a position suitable for the size to some extent, is connected to the fastening member 5 of the blade bolt 1 on the upper surface of the horizontal member 13. At the same time, the bolt 3 side is inserted into the through hole 9 formed in the pillar 11 so that the tip of the bolt 3 does not protrude from the surface of the pillar 11 and penetrates the through hole 9 of the pillar 11 from the bottom of the counterbore 10. The hole 61 or the hole 62 is aligned with the position of the through hole 12 of the horizontal member 13 so that the tip of the bolt 3 is not buried in the hole 9, and the hole 6 (61 or 62) is A bolt 14 is passed through the through-hole 12, and a nut 15 is attached to a tip end of the bolt to attach the fastening member 5 to the horizontal member 1.
3 In addition, a counterbore may be provided also at the end of the through hole 12 of the horizontal member 13.

At this time, if a square root flat bolt having a square root (nut) portion corresponding to the size, preferably the shape, of the hole 6 is used as the bolt 14, the fastening member 5 can be attached to the horizontal member. This is preferable because it can be performed with one wrench.

The column 1 to which the horizontal member 13 is connected
A nut 16 is attached to the tip of the screw 2 of the bolt 3 inserted into the through hole 9 to fasten the column.

[0023]

[Effects of the Invention] The blade bolt of the present invention is constructed as described above. Therefore, the blade bolt of one kind of dimension specification, a horizontal member having a through hole for inserting a bolt at a predetermined location, and a seat boring at all. It is possible to connect a pillar with a dugout or a fixed depth to a fixed depth, so in any case a nut can be attached to the tip of the bolt, and the horizontal member and the pillar can be securely connected There is an advantage that you can.

In addition, there is no need to change the position of the hole provided in the horizontal member according to the thickness of the pillar, so that there is an advantage that it does not take much time to process the building material.

In addition, since it is not necessary to change the position of the hole provided in the horizontal member according to the thickness of the column, the position of the hole can be specified.
Since holes can be formed in advance in all the horizontal members, there is an advantage that a series of operations from processing to assembling of building materials can be smoothly performed.

Also, since the tip of the bolt does not protrude more than necessary from the surface of the pillar, there is an advantage that it does not hinder the construction of the outer wall material. Also, since the bolt screws are not longer than necessary, the mechanical strength is high.
