Description

DETAILED DESCRIPTION OF THE INVENTION The present invention mainly relates to a small and simple suppressing fixture used for mounting and fixing building parts such as sash partitions during construction.

Conventionally, for example, in the installation and fixing of aluminum sash, (1) Driving a V-sash anchor, (2) Memories after dismantling the formwork 3)
Insert the bracket while hanging the sash (<) Weld and secure the V sash to the anchor (5) Fill mortar around the sash (6)
) Removal of the wood (7) Filling the trace with mortar (8) Plastering around the sash (9) 9 steps of caulking The pipe is also required, which is time-consuming and requires skill.

Furthermore, there were other disadvantages, such as the mortar filled in the scars being prone to cracking and having poor water-stopping properties.

The purpose of the present invention is to eliminate these inconveniences and provide a versatile, small and simple suppression fixture,
The feature is that a dogleg-shaped left side plate and an inverted dogleg-shaped right side plate, which can be bent and expanded in the middle, are rotatably connected to the left and right ends of the upper surface of the board, and a protrusion is attached to the upper end of these side plates. These protrusions are loosely fitted into through holes formed at both ends of the pressing plate, and a connector is connected to the intermediate portions of the left and right side plates to shorten the distance between these intermediate portions. The distal end of the piece protruding from the through hole is formed into a blowing portion that bites into the pressure contact surface of the fixed member as the left and right side plates expand as the distance shortens.

Next, one embodiment of the present invention will be described with reference to FIGS. 1 to 3.

(1) indicates a board, and the board (1) is a rectangular metal plate with notches cut in its left and right ends and bent upward to form locking protrusions (la) (la)i, and these protrusions. Piece (ta)
) (ta) and long holes (lb) and t are formed respectively. Furthermore, there is a bolt hole for the anchor bolt in the center of the metal plate (
, IC, )' indicates a suppression plate, and the suppression plate (2) has rectangular through holes (2a) (2a) at both ends and a screw hole (2b)' in the center.
It consists of a rectangular metal plate with a

(3) (3) indicates the left and right side plates, and each of these side plates (3)
) consists of a first plate member (3a) and a second plate member (3b), and the first plate member (3a) has a slightly outwardly curved protrusion (3C)'t at one end and an outwardly curved protrusion (3C) at the other end. A protruding piece slightly bent in the direction (3
d) consists of rectangular metal plates each equipped with a
The second plate member (3b) has a rectangular shape with a protruding piece (3f) that is slightly bent inwardly at one end and has an insertion hole (3e), and a protruding piece (3g) e that is slightly bent inwardly at the other end. Constructed from a metal plate, the protruding piece (3d)' of the first plate member (3a) is loosely fitted into the insertion hole (3e) of the second plate member (3b), so that the left and right side plates (3) can be bent and expanded, respectively. was formed. Further, bolt holes (3h) and (3h)' were formed at one end of the second plate members (3b) and (3b), respectively, into which holes (4a) (described later) are inserted.

Further, a triangular blade or serrated blowing portion (31) was formed at the tip of each of the protrusions (3C).

(4) indicates a connector, and the connector (4) is a long pole)
It consists of (4a) and Nando (4b). Further, (5) indicates a set screw, and the set screw (5) has a head (5a) formed in the shape of a spire.

Next, mounting and fixing of the sash using the metal fittings of the above embodiment will be explained.

The process of driving push-cut anchors and marking after dismantling the formwork is the same as in the conventional case.

Next, press the base m(1)% press plate (2) and the left and right side plates (3) in advance.
)(3), each protrusion (3C) (
ad), (3g)' holes (2a) (3e) (l
b) respectively, and insert the bolts (4a) into the bolt holes (3h) (3h) of the second plate members (ab) (3b) to attach the nuts (4b), and use them as metal fittings as shown in Figure 2. Leave it in assembled condition.

At this time, fix the set screw (5) to the suppression plate (1).

And the side plate (3) of the metal fitting (3).
31) As shown by the dotted line in Figure 3, the sash (7) is secured to the circumferential protrusion ('7a) (7a) of the sash (7), which is the member to be fixed, and the metal fitting is contracted. Attach an appropriate number to the top, bottom, left and right side edges of the Next, suspend the sash (7) with these metal fittings attached to the concrete opening, then tighten each metal fitting (4b), extend the metal fittings as shown in the solid line, and use the anchor bolts (8) to Fix it in the opening. By stretching the metal fittings, each of the first plate members (3a) of the left and right side plates (3) (3) moves upward a little, and the blowing part (31) and the set screw (5) at the tips of the first plate members (3a) move upward.
) is connected to the pressurized surface (7) of the sash (7).
b), and thus the sash (7) is firmly fixed without shifting its position. In this way, the sash (7) is fixed to the opening from four directions: top, bottom, left and right using these metal fittings.

After that, the construction is completed by filling around the sash, plastering around the sash, and caulking.

Therefore, the conventional construction steps of inserting the sash, welding and fixing the sash, removing the sash, and filling the scar with mortar are no longer necessary, which greatly saves time and effort and greatly improves work efficiency. Also, it becomes unnecessary to fill the area with mortar, which improves water-stopping properties. Furthermore, since the base plate (1), press plate (2), and side plates (3) (3) that make up the entire metal fitting are stamped as a single piece, mass production is possible and can be obtained at a low price.

In the above embodiment, the side plate (3) is composed of two plate members, but it is not limited to this. For example, as shown in FIG. It is optional, such as making the groove (3J) flexible. Also, the side plate (3) (3) and the board (1
) may be connected from the beginning with a hinge or the like, unlike the above embodiment. Also, regarding the connector (4), in addition to using the poles (4a) and nuts (4b) in the above embodiment, for example, as shown in FIG. ) may be used to shorten the distance between the intermediate portions of the side plates (3) (3). Furthermore, as shown in Figure 6, the locking piece (6) is attached to the suppressing plate (2) with a set screw (5).
) is rotatably pivoted, and the locking piece (6) is rotated as shown by the arrow to lock the locking portions (6a) (6a) at both ends of the locking piece (6).
The attachment of the metal fittings to the sash (7) may be further ensured by engaging the peripheral protrusions (7a) (7a) of (7).

As described above, according to the present invention, the left and right side plates are expanded by the connecting tool, and with the expansion, the suppressing plate moves upward to press the pressurized surface of the fixed member, and the upper end injection part of the side plate also moves upward. Since it bites into the pressure-contact surface, it is possible to firmly attach and fix the member to be fixed, such as a sash made of aluminum, wood, or synthetic resin, and as mentioned above, the number of steps in installing and fixing the sash is reduced, improving work efficiency. It has the effect of significantly improving the water resistance, improving water-stopping properties, and being versatile as it can be applied to prevent furniture from falling over during disasters such as earthquakes.
