Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a reinforcing metal fitting for a support frame for a sash frame, which can be used to accurately and pre-assemble a sash frame in an opening in a wall formwork. The purpose is to perform the assembling work of a front sash frame accurately and efficiently by simply reinforcing it.

Conventionally, various techniques and devices have been disclosed for the construction of this type of hammer-tipped structure, but these require a large number of parts and require troublesome adjustment operations to ensure dimensional accuracy of the support frame. , it requires a lot of labor and time, which is disadvantageous in terms of workability and economy.

Furthermore, there is also a placket type that is attached so as to protrude in the wall thickness direction, but this requires more types of hardware to accommodate changes in wall thickness, which has the disadvantage of being unreasonable in practice.

This invention has been made to eliminate the above-mentioned drawbacks of the conventional art. Next, the structure of this invention will be explained with reference to the drawings of embodiments.

Figure 1 is a perspective view of the first embodiment, Figure 2 is A of Figure 11.
- 1 vertical position on line A'2
FIG. 3 is a cross-sectional view taken along line BB in the figure.

■ is a plate-like, approximately triangular metal fitting main body, and the - side (horizontal (III)) has a step part 2 formed by bending it horizontally in the front direction, and is further connected to it and vertically extending it. The needle hole 3a is formed by bending, and mounting pieces 3 (=J) are provided in series.

Reference numeral 4 indicates a reinforcing piece that is partially cut and raised near the medium heat of the above-mentioned step section 2 and section 3 and extended perpendicularly thereto.

Reference numeral 5 denotes a mounting piece with a nail hole 5a provided by extending the other side (vertical side) perpendicular to one side (horizontal side) of the metal fitting main body 1.

This contact piece is partially cut and raised in the direction of the stepped portion 2 and the reaction force direction (back direction) at an appropriate inner band along the attachment piece 5 of the six-cigarette cigarette.

Note that 7 indicates a reinforcing lip formed on the other slope portion of the metal fitting main body 1.

When using the reinforcing metal fittings of this first embodiment formed as described above, the upper and lower pieces a, a and the left and right pieces b-@ are combined symmetrically within the same plane as shown in Fig. 4. After constructing the support frame A with its four corners joined in an overlapping state, the stepped part 2, the recessed piece 3, and the auxiliary piece 4 of the reinforcing metal main body 1 are attached inside the four corners of this support frame A. At the same time, by engaging the mounting piece 5 and the contact piece 6 on the other side and nailing and fixing the mounting pieces 3 and 5 to the support #A, the four corners can be reinforced. can.

Next, as shown in FIG. 5, the framed support #A is fixed to a predetermined position on the inner surface of the inner formwork Pi of the wall with nails, etc., and the molds '4:AJ3, B and sashes are attached along the outside. A curing frame in which the frame C is assembled is fitted into the outer periphery of the support frame A and supported.

Furthermore, after fixing the supporting frame A to the outer inner surface of the curing frame with nails or the like, the outer formwork IJ- is erected to assemble the formwork for the wall opening.

In order to maintain the spacing between the wall forms, separators S can be attached and tightened by penetrating near the center (or at the four corners) of the support frame A, as shown in FIG.

P' indicates the opening of the inner formwork and the outer formwork.

In addition, the method for installing the outer support frame A is not limited to the method described above. You can also use this method.

Concrete is poured into the wall formwork as described above, and after curing, the outer formwork, inner formwork, etc. can be dismantled and removed, and the sash frame can be attached to a predetermined position in the opening.

According to this first embodiment, since the metal fittings are integrally formed from a single iron plate, the dimensional accuracy of the metal fittings is high, and it can be easily fixed to the four corners of the support frame for appropriate reinforcement. It is expected that frame assembly work will become more efficient.

Therefore, the number of parts is small and the construction can be carried out rationally.

Next, another embodiment of the invention will be described.

FIG. 6 is a perspective view of the second embodiment, showing stepped portions 22.7', .22 and mounting pieces 23.7' with nail holes 23a, 25a perpendicular to one side and the other side of the metal fitting body 21, respectively. 25
It is a form in which the two are connected together.

In this case as well, it can be formed integrally from a single iron plate, and the same functions and effects as in the first embodiment can be expected, and it can also be used in any of the four corners, which is advantageous for installation work, management, etc. It is.

FIG. 7 is a perspective view of the third embodiment, in which a stepped portion 32 and a separate mounting piece 3 with a nail hole 33a are provided along one side of the metal fitting main body 31.
3 is fixed, and a mounting piece 3 with a nail hole 35a is attached on the other side.
5 are integrally arranged in series, and an opening 31a may be provided near the center of the metal fitting main body 31 to make it lightweight.

In this case, the attachment piece 35 of the metal fitting body 31 does not include an abutment piece.

FIG. 8 is a perspective view of the fourth embodiment, in which the metal fitting main body 41 includes a mounting piece 43 having a stepped portion 42 on one side, a mounting piece 45 on the other side, and a diagonal in which these are integrally joined. At the same time, a mounting piece 43 on one side and an L-shaped contact piece 46 are provided at each base end of the diagonal piece 1b.

FIG. 9 is a perspective explanatory view of the reinforcing metal fittings of the second embodiment taken from a support frame A assembled in a different manner, and another one is installed on the front side of the four corners of the support frame A. Reinforcement play 1-
E is connected by nailing it together.

FIG. 10 is a perspective view of the fifth embodiment, the eleventh part and the twelfth part.
The figures are an explanatory view of the left side with the reinforcing metal fitting of the fifth embodiment placed at the upper left corner and an explanatory view of the right side with the reinforcing metal fitting placed at the upper right corner, with the temporary thick part of the metal fitting body 5I as the neutral axis. On one side (horizontal side) and the other side (vertical side), a stepped portion 52 and a mounting piece 53 protrude toward the front.
53i, all of the contact pieces 56 and 56 protruding toward the rear surface, and the reinforcing pieces 54 extending on the neutral axis are formed in the same arrangement.

According to the fifth embodiment, the same reinforcing metal fittings can be used in common at any of the four corners of the support frame A, which is more advantageous in terms of installation work and management.

According to the reinforcing metal fitting of the present invention constructed and used as described above, the four corners of the support frame can be easily and accurately reinforced with a simple structure and a small number of parts. In comparison, it is expected that workability and assembly accuracy will be improved.

In addition, there is no need for complicated dimensional adjustments, which shortens the construction period.
The opening space can be large, which is advantageous in practice.

Furthermore, compared to the conventional technique in which brackets are provided protruding in the wall thickness direction for support, there are fewer types of metal fittings, making handling and management easier.
