[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a method for mounting a curtain wall, which constitutes an outer wall or a partition wall of a structure such as a building, at a predetermined angle such as vertical to the structure. The present invention relates to a temporary jig for a curtain wall to be provided.

[0002]

2. Description of the Related Art In recent years, in a structure such as a building, for example, a curtain wall is installed by forming a space section in front of a beam which is a frame such as a steel frame or RC as a structural body, and the curtain wall is attached to an outer wall or a partition. The method of configuring as a wall has been frequently used. As the material of the curtain wall, there are a metal panel, a glass plate, a precast concrete plate and the like. For example, if a glass plate is applied, it is possible to construct a building entirely covered with glass. In order to mount this curtain wall on a beam while standing upright, it is common to bolt the common mounting brackets provided on both sides, but before that, bolts are attached to the lower part of the mounting surface of the curtain wall. The amount of projection of the bolt from the framework is adjusted to maintain the curtain wall in a vertical state, that is, a temporary state. This bolt is
It is usually screwed into a nut welded to the front of the beam.

[0003]

As described above, the temporary means for welding the nut to the front surface of the beam and vertically adjusting the posture of the curtain wall with the bolts screwed into the nut requires a large number of curtain walls. Bolts and nuts (usually two pairs). Therefore, the number becomes huge, and the work of welding the nut to the beam and screwing the bolt into the nut at the site becomes complicated, and it takes a long time to install the curtain wall. There was a danger in screwing in because the operator had to lean halfway on the front of the beam.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a curtain wall temporary jig in which temporary installation of a curtain wall can be easily performed in a short time, and worker safety can be achieved. The purpose is.

[0005]

SUMMARY OF THE INVENTION The present invention has been made to achieve the above object, and has a jig body detachably attached to a structure by a fixing means, and the jig body has a structure. An angle adjusting member that is steplessly advanced toward a mounting surface of the curtain wall with respect to the structure in a state where the jig body is attached to the structure, and the jig body can be attached to and detached from the structure from below. It is characterized by having been constituted so that.

[0006]

According to the curtain wall temporary jig of the present invention, since it can be attached to and detached from the structure, there is no need to provide for each of a large number of curtain walls, and the number thereof can be minimized. In addition, since the fixing means can be operated from below for attaching and detaching the structure, it can be performed easily and in a short time, and is safe.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows a state in which a curtain wall 2 is vertically installed via a mounting bracket 3 on a front surface (a left side surface in the figure) of a horizontal beam (structure) 1 forming a framework of a building or the like. ing. Beam 1 has flanges 4 and web 5
H-shaped steel, which is constructed such that the flanges 4 are horizontal. The mounting bracket 3 is an L-shaped bracket, and is fixed to the curtain wall 2 and the flanges 4 of the beams by bolts and nuts, and the two are connected. The curtain wall 2 is in this case a rectangular precast concrete slab.

Now, before the curtain wall 2 is installed on the beam 1, as shown in FIG. 2, the vertical state is maintained by the temporary jig K of the present embodiment.

As shown in FIGS. 3 and 4, the temporary jig 5 has a jig body 7 which is detachably attached to the flange 2 of the beam 1 by fixing bolts (fixing means) 6.
And with the jig body 7 attached to the beam 1,
An adjusting bolt (angle adjusting member) 8 is provided to advance toward the mounting surface 2a of the curtain wall 2 with respect to the beam 1.

The jig body 7 is provided with a short plate portion 10, 11 of a holder 12 composed of a long plate portion 9 and upper and lower short plate portions 10, 11 which are formed by cutting a channel steel having a U-shaped cross section. The nuts 13 and 14 are respectively welded, and a horizontal plate 15 having a wedge-shaped cross section is welded to the inner surface of the upper short plate portion 10.

Nut 13 welded to upper short plate 10
Is a hexagonal nut whose length is the same as that of the short plate portion 10, and one of the six surfaces has a short plate portion with its axis extending along the direction in which the short plate portion 10 extends from the long plate portion 9. 10 are welded to the outer surface. The adjustment bolt 8 is screwed into the nut 13 from outside (left side in FIG. 2).

Nut 14 welded to lower short plate 11
Is a general hexagonal nut, and one axial end face is welded to the outer surface of the short plate portion 11. And this nut 14
Then, the fixing bolt 6 is screwed into the fixing bolt 6 from below, and the fixing bolt 6 is inserted into a bolt insertion hole 11 a formed in the short plate portion 11.
And enters the holder 12.

The horizontal plate 15 is welded to the inner surface of the short plate portion 10 and its surface (lower surface) 15a is parallel to the outer surface of the upper short plate portion 10.

Next, the method of using the temporary jig K of this embodiment will be described. First, as shown in FIG. 2, the upper surface of the lower flange 4 on the front surface of the beam 1 corresponding to the lower portion of the curtain wall 2 Then, with the surface 15a of the horizontal plate 15 abutted, the flange 4 is sandwiched in the holder 12, and the fixing bolt 6 is screwed in to fix the whole to the flange 4. In this state, the adjustment bolt 8 screwed into the nut 13 becomes horizontal, and advances to the front side of the beam 1 steplessly.

After the temporary jig K is fixed to the lower flange 4 of the beam 1 as described above, the beam 1 is temporarily fixed to the beam 1 in a loose state by the mounting bracket 3. Then, the head 8a of the adjusting bolt 8 is applied to the mounting surface 2a of the curtain wall 2, and the amount of screwing into the nut 13 is adjusted to change the amount of protrusion to the mounting surface 2a, while the vertical position of the curtain wall 2 is maintained. Adjust to When the curtain wall 2 becomes vertical,
Finally, the mounting bracket 3 is fixed to the beam 1 and the curtain wall 2, and the installation of the curtain wall 2 is completed. Two temporary jigs K are prepared for one curtain wall 2, and the heads 8 a of the adjustment bolts 8 come into contact with both ends in the width direction of the curtain wall 2 at positions avoiding the mounting bracket 3. . When the installation of the curtain wall 2 is completed, the fixing bolt 6 is loosened and the temporary jig K is removed from the beam 1.

According to the temporary jig K, since it can be attached to and detached from the beam 1, there is no need to provide bolts and nuts for each of a large number of curtain walls unlike the conventional means, and the number is minimized. be able to. Also, the work of attaching and detaching the beam 1 can be performed easily and in a short time because the fixing bolt 6 is simply tightened and loosened.
Since the operation with respect to the fixing bolt 6 can be performed from the lower side of the beam 1, there is no need to lean over the front of the beam 1 and it is safe.

[0017]

As described above, according to the curtain wall temporary jig of the present invention, since it can be attached to and detached from a structure, there is no need to provide for each of many curtain walls, and the number of curtain walls is minimized. It is possible to install and remove the structure from the bottom, so that the temporary installation of the curtain wall can be performed easily and in a short time, and it can be safely attached to the structure. It has the effect of being able to.
