Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a base metal fitting that can be stably mounted on a foundation and that can accurately and reliably support a wall panel.

[Conventional technology]

To erect a wall panel on the foundation, as shown in Fig. 6, a leg piece C is placed on the foundation f and fixed to an anchor bolt b, and a receiving piece d supports the lower end of the wall panel p. A base metal fitting e consisting of is used.

[Problem to be solved by the invention]

However, although the top surface of the foundation f has been leveled by pouring mortar or the like, since it is in a rigid shape, there are many unevenness on the surface, resulting in an irregular condition.

Therefore, when the leg piece c-it- is placed on the upper surface of the base ilf, the leg piece C will come into contact with the convex part of the uneven surface, and as a result, the leg piece d will not be able to be installed properly and will wobble. There is a problem in that the wall panel p cannot be attached to a predetermined position due to vibration at the tip of the wall panel p.

In particular, when a plurality of wall panels p are arranged side by side, the wall surface becomes irregular, deteriorating the appearance of the house, and requiring time and effort to repair it.

In the present invention, when the leg pieces are formed using an elastic material, the leg pieces are basically curved upward in a convex manner in advance, so that the leg pieces can be firmly fixed without wobbling, and the wall panel can be fixed firmly. The aim is to provide foundation metal fittings that can increase precision and improve the quality of houses.

[! l, i! [Means for Solving Problem 1] The present invention provides a structure in which a support piece supporting the lower end of a wall panel and an anchor bolt are installed on the top surface of the foundation, and a nut screwed onto the anchor bolt is screwed onto the top surface of the foundation. The base metal fitting includes a leg piece to be fixed, and the leg piece is made of an elastic material that deforms when the nut is screwed, and the leg piece is curved upward in advance in a convex manner.

[Effect]

Since the leg piece is curved upward in advance in a convex manner, when the nut is tightened, both ends of the leg piece reliably come into contact with the upper surface of the foundation, and the leg piece can be installed without wobbling.

Moreover, since the leg pieces are made of an elastic material that deforms when screwed into the nut, the leg pieces themselves function as spring washers, which prevents the nuts from loosening and allows them to be firmly fixed on the foundation. .

Therefore, the tip of the receiving piece does not swing and can be accurately positioned at a predetermined position, allowing the wall panel to be supported accurately and reliably.

〔Example〕

An embodiment of the present invention will be described below based on the drawings.

In the figure, the foundation metal fitting 1 of the present invention includes a leg piece 3 fixed to the upper surface of the foundation F by a napht 12 that is placed on the upper surface of the foundation F and is screwed into the anchor bolt 2, and a wall. It is provided with a receiving piece 4 that supports the lower end of the panel P.

Basic! F is arranged along the longitudinal direction of the wall panel P, and a plurality of anchor bolts 2-. are installed side by side at appropriate intervals with their upper ends protruding from the upper surface of the base IF. The top surface of foundation F will be leveled at the top.

In this embodiment, the wall panel P is a rectangular framework formed by connecting both ends of an upper frame member 21 and a lower frame member 22 with side frame members, and side plates 23.
24 attached thereto, and grooves 25 extending in the longitudinal direction of the lower frame member 22 are carved on the lower surface of the lower frame member 22 over substantially the entire width of the wall panel P.

As described above, the base metal fitting 2 is formed by joining the leg pieces 3ε and the receiving pieces 4 in an L-shape, and in this embodiment, it is formed as a long body having a length approximately equal to the width dimension of the wall panel P. .

1V of the anchor bolt 2 is attached to the leg piece 3! A plurality of holes 5 are bored at a pitch substantially equal to the spacing, and the holes 5 are set to have a diameter larger than that of the anchor bolt 2, and in this embodiment, the diameter is set to be twice or more.

Furthermore, the base metal fitting 2 is integrally formed with the leg piece 3 and the receiving piece 4 by bending an elastic plate such as a spring-like plate, and in this embodiment, the leg piece 3 is formed by forming the plurality of holes in advance. 5
- It is curved upward in a convex arc around the axis connecting the lines. The arc height δ of the curve is a height that can absorb the roughness of the unevenness on the upper surface of the foundation F, that is, 1.0 mm or more and 1.51 mm.
The following is desirable.

In this embodiment, a fixing plate 11 is placed on the upper surface of the leg piece 3. Fixed plate 11 is a rectangular board 6 having a through hole 7 in the center of which the anchor bolt 2 is inserted without leaving a gap, a boss part 9 surrounding the through hole 7 and hanging from the board 6, and a VX board. 6, and four downwardly directed claw pieces 10 formed at the four corners of the periphery of the main body 6.

The fixing plate 11 is made of a steel ring elastic material. In this embodiment, the boss portion 9 is formed by squeezing the base 6 at the periphery of the through hole 7, and the claw pieces 10 are formed at each corner of the base plate 6. By bending downward, each is formed integrally with the base @6.

In the boss portion 9, the height H of the lower surface 9a from the lower surface of the substrate 6 is determined by the thickness T of the leg piece 3 and the time, as shown in FIG. More specifically, the distance HO between the lower surface 9a of the boss portion 9 and the lower surface 10a of the claw lO needs to be at least smaller than the thickness T of the leg 3.

In addition, in this embodiment, the center O position of the through hole 7 is set in the direction along the receiving piece 4 of the base metal fitting 1 with respect to the center of the substrate 6 and the receiving piece 4.
It is eccentric by the length of X and Y in the direction perpendicularly adjacent to .

By deviating the center position O of the through hole 7 and the center position of the base plate 6 in the vertical and horizontal directions in this way, the installation error of the anchor bolt 2 is absorbed, and the hole 5 of the base metal fitting 1 The substrate 6 can be placed on the upper surface of the leg piece 3 so as to straddle the leg piece 3.

Then, the anchor bolt 2 is inserted into the hole 5 of the base metal fitting 1, the receiving piece 4 is positioned at a predetermined position, and the base metal fitting 1 is placed on the upper surface of the foundation F. A fixing plate 11 is placed on the upper surface of the rear leg piece 3 with the claw piece 10 facing downward and the through hole 7 inserted into the anchor bolt 2. A nut 12 which is screwed onto the anchor bolt 2 is screwed onto the upper surface of the fixing plate 11 with a flat washer 31 and a spring washer 32 in between.

As the nuts 12 are screwed in, the fixing plate 11 presses the substrate 6 with its claws 10. During the pressing, the fixing plate is guided to the anchor bolt 2 by the boss portion 9, so there is no lateral displacement, and since the boss portion 9 is formed to match the thickness and time of the leg piece 3, the lower surface of the boss portion 9 The leg piece 3 can be reliably pressed by the claw piece 10 without coming into contact with the upper surface of the foundation F.

In the case of the base metal fitting 1, since the leg piece 3 is made of an elastic material and is curved in a convex manner in advance, the radius of curvature gradually increases due to the pressure of the claw piece lO, and if unevenness exists on the upper surface of the foundation F. However, since both ends of the leg piece 3 abut against the upper surface of the foundation F, it is fixed to the foundation F in a stable state without wobbling, and the receiving piece 4 does not shift or tilt.

Therefore, the lower end of the wall panel P fitted into the receiving piece 4 is held in an accurate position.

In addition, when screwing the nut 11 in the base metal fitting 1 of the present invention, it is not necessary to use a fixing plate as shown in FIG. It can also be bent into a mountain shape with the top facing upward, and the present invention can be modified into various forms.

〔Effect of the invention〕

Like a ridge, the base metal fittings of the present invention have the leg pieces placed on the top surface of the foundation curved in advance in an upwardly convex manner, so that both ends of the leg pieces reliably come into contact with the top surface of the foundation, causing wobbling. In a stable condition without any problems! It can be fixed to the IE foundation.

In addition, since the leg piece is made of an elastic material that deforms when screwed with the NAND, the leg piece itself functions as a spring washer to prevent the nut from loosening, and the leg piece can be firmly fixed on the foundation. I can do it.

Therefore, the tip of the support piece can be accurately positioned at a predetermined position without swinging, and the wall panel can be supported accurately and reliably, increasing the accuracy of wall panel construction and improving the quality of the house. I can do it.
