Abstract

PROBLEM TO BE SOLVED: To make a longitudinal frame and a building frame relatively movable in the in-plane direction by connecting a fixing part, welded to a joint bar, to the fitting piece of a body to be fitted to the longitudinal frame, in such a way as to be movable in an in-plane direction. SOLUTION: A longitudinal frame 1 forming a sash is formed into sectional shape with an outward recessed groove 3 at the indoor side part of a body 2, and an anchor 4 fitted to the recessed groove 3 is welded to a joint bar 5 to fit the longitudinal frame 1 to the longitudinal edge part of a building frame 6. A fitting piece 14 is slidably inserted in a fixing member 11 to fit a protrusion 15 slidably into a long recessed part 18, thus making a body 10 and the fixing member 11 movable in the direction of arrow marks. With the body 10 fitted to the opening edge of the outward recessed groove 3 of the longitudinal frame 1 and with the fixing member 11 welded to the joint bar 5, the fitting piece 14 of the body 10 becomes slidable in the in-plane direction in relation to the fixing member 11. The longitudinal frame 1 can thereby be moved in the in-plane direction in relation to the side edge part of the building frame 6 so as to be able to absorb displacement between layers.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an anchor for attaching an upper frame or a vertical frame constituting a sash frame to a building frame.

[0002]

2. Description of the Related Art Various types of anchors are known for attaching an upper frame or a vertical frame constituting a sash frame to a building frame. For example, an anchor is known in which a fixing piece is integrally provided on a main body that is locked and fixed to a frame, and the fixing piece is welded to a differential bar embedded and fixed in a building body.

[0003]

According to such an anchor, the upper frame and the vertical frame can be firmly attached to the building frame in the in-plane direction and the out-of-plane direction, but on the other hand, when the building frame is displaced between layers during an earthquake. , The sash frame may be deformed because the building frame, the vertical frame, and the upper frame cannot move relative to each other in the in-plane direction.

For example, a rigid plate such as a PC plate or an ALC plate is connected to the upper building frame and the lower building frame by fasteners so that interlayer displacement can be absorbed, and the left and right rigid plates, the upper building frame and the lower building frame open the openings. When the sash frame is attached to the opening and the vertical frame that makes up the sash frame is connected to the vertical edge of the rigid plate by an anchor, the upper building frame and the lower building frame are displaced between layers and the upper frame When the lower frame moves in the opposite direction in the in-plane direction, the vertical frame cannot move in the in-plane direction with respect to the rigid plate, so the sash frame may be deformed.

In order to prevent the deformation of the sash frame described above, it is not necessary to connect the vertical frame and the vertical edge of the rigid plate. However, in this case, strong wind and rain exerts an out-of-plane force on the vertical frame. When you do, the vertical frame may be curved.

Therefore, an object of the present invention is to provide an anchor for mounting a sash frame which can solve the above-mentioned problems.

[0007]

An anchor for mounting a sash frame, which includes a main body attached to a frame forming a sash frame and a fixing member fixed to a building frame side, and the main body and the fixing member are connected so as to be relatively movable.

[0008]

[Operation] The main body is attached to the frame that constitutes the sash frame, the fixing member is fixed to the building frame side, and the frame is attached to the building frame, so that the frame and the building frame can move relative to each other in the in-plane direction. It is possible to absorb the interlayer displacement and prevent the sash frame from being deformed.

[0009]

[Examples] As shown in FIG. 1, a vertical frame 1 forming a sash frame has a cross-sectional shape having an outward groove 3 on an inner side of a main body 2 and is attached to the outward groove 3. The anchor 4 is welded to the differential bar 5 and attached to the vertical edge of the building frame 6.

The anchor 4 includes a body 10 and a fixing member 11
2, the main body 10 of which, as shown in FIG.
2, a pair of locking pieces 13 and a mounting piece 14 are cut and raised to be integrally provided. The mounting piece 14 has an arc-shaped protrusion 15
Are integrally provided, and the fixing member 11 includes a horizontal piece 16 and a pair of hook pieces 1 integrally provided at both ends of the horizontal piece 16.
7, 17 has a substantially C-shaped cross section, and a long recess 18 is formed in the lateral piece 16, and the cross section of the long recess 18 has a substantially semicircular shape.

Then, as shown in FIG. 3, the mounting piece 14 is slidably inserted into the fixing member 11 so that the projection 15 is formed into the long concave portion 18.
The main body 10 and the fixing member 11 are slidably fitted to the main body 10 and movable in the direction of the arrow.

The main body 10 is attached to the opening edge of the outward concave groove 3 of the vertical frame 1, and the fixing member 11 is welded to the streak 5, whereby the mounting piece 14 of the main body 10 is fixed.
1 can be slid in the in-plane direction.

Therefore, since the vertical frame 1 can move in the in-plane direction with respect to the side edge of the building frame 6, the interlayer displacement can be absorbed, and the mounting piece 14 of the main body 10 moves in the out-of-plane direction with respect to the fixing member 11. Since it does not move, it is possible to prevent the vertical frame 1 from being bent and deformed by strong wind and rain.

In particular, since the mounting piece 14 of the main body 10 has a flat plate shape facing the out-of-plane direction, the strength of the mounting piece 14 in the out-of-plane direction is large, so that the vertical frame 1 can be firmly supported in the out-of-plane direction.

Next, a second embodiment of the present invention will be described. FIG.
As shown in FIG. 5 and FIG. 5, the main body 10 is formed into a U-shape by the horizontal piece 12 and the pair of side pieces 19 and 19 and the outward concave groove 3 of the vertical frame 1.
It is adapted to be slidably fitted in the inside in the longitudinal direction so as to be attached, and in this way, the vertical frame 1 is the main body 10 of the anchor 4.
It becomes possible to move in the longitudinal direction (vertical direction).

Although the anchor 4 is used for mounting the vertical frame 1 in each of the above-mentioned embodiments, it may be used for mounting the upper frame. In this case, the upper edge of the building frame and the upper frame are vertically opposed to each other. It is possible to prevent the deflection and cleaving of slabs, burrs, etc. that move and absorb the vertical displacement at the time of an earthquake as well as absorb the layer displacement.

Next, a third embodiment of the present invention will be described. FIG.
As shown in FIG. 2, the upper frame 20 has an upward concave groove 21, and an anchor 22 attached to the upward concave groove 21 is welded to an L-shaped member 24 fixed to the upper edge portion of the building frame 23 to form the upper and lower frames 2.
0 is attached.

As shown in FIGS. 7 and 8, the anchor 22 is composed of a main body 25 and a fixing member 26. The main body 25 has locking pieces 28 integrally provided at both ends of a plate-like body 27 and the plate thereof. An elongated hole 29 in the in-plane direction is formed in the plate-like body 27, and the fixing member 26 is L-shaped with one side piece 30 and the other side piece 31, and the one side piece 31 is formed in the plate-like body 27 with the long hole. The main body 25 and the fixing member 26 are relatively movable in the in-plane direction by being connected by a fixing tool 32 such as a rivet or a bolt and nut which is inserted through 29. In addition, a sliding material is coated or attached to the contact surface between the plate-shaped body 27 and the one side piece 30 to facilitate movement.

The main body 25 is formed by the upward concave groove 2 of the upper frame 20.
1, the other side piece 31 of the fixing member 26 is attached to the L-shaped member 2
4, the upper frame 20 is attached to the upper edge of the building frame 23.

In this way, the upper frame 20 can move in the in-plane direction relative to the upper edge of the building frame 23, so that interlayer displacement can be absorbed.

[0021]

The main body is attached to the frame forming the sash frame,
By attaching the fixing member to the building frame side and attaching the frame to the building frame, the frame and the building frame can move in the in-plane direction relatively, so that interlayer displacement can be absorbed and deformation of the sash frame can be prevented.
