Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a method for fixing an end part of a house floor to a concrete foundation.

(Prior art and problems) As shown in Fig. 6, the conventional method for fixing the end of the main drawer is to attach the recess for the main hook C to the upper end of the inner surface of the concrete foundation a. As soon as the end was inserted, the vicinity of the end was supported from below by the bundle d and fixed by the roots e and f, which made the work very complicated.Moreover, the bundle d also had many stones including the bundle g. The cost was high because it required parts. In addition, the bottom surface of the recess d is leveled with mortar h at the same time as the top of the concrete foundation a, but since it is a recess, it is difficult to level it completely, and this causes the wobbling of the large pull C. It also caused poor construction accuracy.

(Purpose of Solving the Problem) The present invention is a method of attaching the end of a large wire at right angles to the inner surface of a concrete foundation using a receiving metal fitting, in which a fixing bolt is embedded to fix the receiving metal fitting to the concrete foundation. Another feature is the fixing method.

(Example) Hereinafter, the configuration of the present invention will be described with reference to the drawings.

FIG. 4 shows the receiving metal fitting 2 used in the present invention. This receiving metal fitting 2 is formed by bending a single metal plate, and is formed by raising up both side edges of the receiving plate 6, and holding plates 7.7 for holding the ends of the main drawer. The rear end of 6 is made to hang down to form a mounting plate 5 for attaching the receiving metal fitting 2 to the concrete foundation 4. Two or more bolt insertion holes 8 are formed in the mounting plate 5. Furthermore, a claw piece 9 is provided on the inner surface of the holding plate 7.7 and projects diagonally downward. The claw piece 9
It is preferable to partially cut and raise the holding plates 7, 7 and bend them inward. The shape of the receiving metal fitting 2 is not limited to a two-piece shape. For example, as shown in FIG. 5, a reinforcing rib plate 10 may be provided between the receiving plate 6 and the mounting plate 5;
The rear end portion between both the clamping plates 7, 7 may be closed by the back plate 30.

Next, a description will be given of means for attaching the receiving metal fitting 2 configured in this way to the concrete foundation 4.

As shown in FIG.
Attachment hole 1 of bottom plate work 5 of dish-shaped embedded box 14 through
6.16 and tighten the nut 12.1 from the inside of the bottom plate 15.
The fixing bolts 1111 are attached to the embedded box 14 by screwing the fixing bolts 1, 1, and 2 into the threaded portions of the fixing bolts 1, 1, and 11, respectively.

The rear end of the fixing bolt 11.11 projects outwardly from the base plate 15.

Next, after assembling the temporary frame 17, the embedded box 14 with the fixing bolts 1111 is attached to the upper end of the temporary frame 17 using the inverted-shaped retaining rod 18°18 provided at the upper end of the push-in box 14. Hook it onto the inside of the temporary frame. At that time, the position adjustment screws 1 screwed into the latching rods 18, 18
9. Adjust the installation height of the embedded box 14 by turning the knob 19 so that the embedded box 14 is in the predetermined position, in other words, the fixed pole 1-11.11 is in the predetermined buried position. Next, concrete is poured, and the retaining rods of the embedded box 14 are fixed at 18°1.
Level adjustment plate 20°20 protruding from the rising part of 8
Level the top using the concrete and construct foundation 4 (concrete). After the concrete has hardened, the temporary frame 17 is first dismantled one by one, and finally the Nandos 12 and 12 are removed and the embedded box 14 is removed from the concrete foundation 4 to complete the work.

Fixing bolt 11 whose rear end is buried in concrete foundation 4
．． 11, as shown in FIG. 1 and FIG.
Screw the nuts 12°12 onto the threaded portions of the fixed poles I-11 and II through the screws.

In this way, the receiving metal fitting 2 is fixed to the inner surface of the concrete foundation 4. Nut 12.12 is fixing bolt 11.11
It was used when burying.

To fix the end of the Ohiki l to the receiving metal fitting 2 which is fastened to the fixing bolt 11 of the concrete foundation 4, as shown in Figs. Using a mallet or the like, forcefully insert the screw into the space between the two clamps Fi, 7.7 from above, and bring the bottom surface of the large puller L into contact with the top surface of the receiving plate 6. At this time, the claw pieces 9 protruding from both the holding plates 7, 7 bite into both side surfaces of the end of the large pull 1, and the end of the large pull 1 is firmly fixed by both the holding plates 7, 7. The end of the Ohiki is a concrete foundation 4
fixed at right angles to the inner surface of the This fixation is done by holding the two clamping plates 9
．． A nail hole may be drilled in 9 and the end of the drawer 1 may be nailed.

(Effects of the Invention) The present invention is characterized in that the end of the large pull is placed on a receiving plate, and a receiving metal fitting provided with a clamping plate for holding both sides of the end of the large pull is attached to the inner surface of a concrete foundation. , the end of the daihiki is fixed to the concrete foundation at right angles through this receiving metal fitting. Therefore, the end of the Ohiki can be securely fixed to the concrete foundation without wobbling, which improves work efficiency.
Economical efficiency will be greatly improved. In addition, the end of the drawer can be fixed simply by fitting it into the receiving metal fitting, which improves work efficiency.

Further, the end of the main drawer is supported and fixed by a receiving metal fitting, and the receiving metal fitting is fastened to a fixing bolt horizontally fixed to the concrete foundation using an embedded box. Therefore, the installation position of the Ohiki is accurate and the construction accuracy is high. Furthermore, since the receiving fitting is formed by bending a single metal plate, material costs can be reduced, which also contributes to improving economic efficiency.
