Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a structure for mounting a concrete wall panel by a curtain wall construction method through a mounting metal fitting to a steel frame column constituting a building frame.

[0002]

[Prior Art]

 When a wall panel is attached to a building frame, it is a common practice to attach metal parts to both the frame side and the wall panel side, and to engage them by engaging them. In this installation, generally, beams of the building frame are used in the case of so-called vertical lining, but beams cannot be used in the case of horizontal lining, so it can be done by using columns (steel columns). There is.

As a wall panel mounting structure using steel columns, there are means disclosed in, for example, Japanese Patent Application Laid-Open No. 61-165444 and Japanese Patent Application Laid-Open No. 1-158142. In these technologies, a locking piece that extends to the left and right is provided on the steel column, and a locking plate is used to attach the side edge of the wall panel to the locking piece by using a lightning plate. ..

In the mounting technique as described above, as described in the former publication, simply bolting the lightning plate to the wall panel causes the plate to be loosened when the port is loosened. Since there is a concern that the wall panel will be unlocked when it rotates, it is necessary to finally secure the steel frame side locking piece and the lightning plate by welding or the like. However, if it is fixed in this way, it will be inferior in so-called earthquake resistance. Therefore, the former technique discloses that the lightning plate is reliably fixed in the above method without welding or the like, and seismic resistance is also secured.

[0005]

[Problems to be solved by the device]

 However, even with the above technology, the earthquake resistance is still insufficient. In other words, it is necessary to consider horizontal force in particular for earthquake resistance to prevent damage to wall panels. When the curtain wall receives a horizontal force, the wall panel is set to slide or rotate relative to the horizontal displacement of the building body to absorb the displacement. If the wall panel is so-called vertical, the upper and lower beams of the building frame support the panel, so it is easy to deal with the above displacement, but if it is horizontal, the wall panel can also be supported by the above-mentioned technique. As long as it is hooked at the side, it is limited to the metal object, so it is difficult to set it so that the amount of displacement due to horizontal force can be absorbed sufficiently. The present invention has been made in view of the conventional problems as described above, and provides a wall panel mounting structure capable of sufficiently absorbing the above displacement amount, simplifying the structure, and facilitating construction. The purpose is.

[0006]

[Means for solving the problem]

 In order to achieve the above-mentioned object, the wall panel mounting structure according to the present invention has a ruler angle of a required length on the upper and lower surfaces of the horizontal piece of the base metal which is made by projecting and joining the horizontal piece to the steel column of the building frame. A nut on which the metal fittings that are joined so that each standing piece is parallel to the wall panel surface to be attached and the locking piece that is h-shaped in side view are formed, and the height adjustment bolt is screwed into the locking piece. The lower metal fitting attached to the lower part of the inner surface of the wall panel and the upper metal fitting attached to the upper part of the inner surface of the wall panel with the locking piece formed as an inverted h shape in side view. The lower metal piece of the upper side wall panel is locked to the vertical piece of the above, the height is set by the height adjustment bolt, and the ruler angle and the lower metal object are welded and fixed. Sliding the upper side hardware of the lower side wall panel It is a stopped configuration.

[0007]

[Action]

 When an earthquake occurs and horizontal force is applied, the lower part of the wall panel moves and displaces following the horizontal displacement of the steel column, but the upper part of the wall panel allows the upper hardware to slide relative to the ruler angle. Since it is only stopped, it does not follow the above displacement, that is, it moves relative to the ruler angle. This relative movement can be sufficiently absorbed regardless of the amount of displacement, since there is no special restriction member in the movement direction. Further, since the wall panels are attached at a fixed angle in which the upper and lower wall panels are joined to the base metal fittings at one place, the member structure is simple and the construction can be concentrated.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing the structure before the wall panel is attached to the building frame by the mounting hardware, FIG. 2 is a side view of the main part showing the state in which the wall panel is attached to the building frame, and FIG. FIG. 9 is a view taken along the line AA in FIG.

In the drawing, reference numeral 1 denotes a steel frame column (a part of an H-shaped steel is shown in the figure) that constitutes a building frame, and upper and lower end portions of wall panels P located above and below the outer surface of the steel frame column 1. At the portion where is located, an angle-shaped base metal fitting 2 is made orthogonal to the steel frame pillar 1 and joined by welding or the like so that the horizontal piece 2a projects. Although not shown, a reinforcing rib may be appropriately attached to the inner corner formed by the horizontal piece 2a and the upright piece 2b as necessary for bending stress resistance.

Reference numerals 3 and 4 are ruler angles joined to the upper and lower surfaces of the horizontal piece 2a by welding or the like, and have substantially the same length as that of the base metal 2, and the respective standing pieces 3a and 4a form a surface of the wall panel P. They are joined so that they are flat and the entrance and exit levels are the same. The metal fittings on the skeleton side are composed of the above-mentioned base metal fitting 2, the upper and lower ruler angles 3 and 4.

Reference numeral 5 denotes a lower metal fitting to which a mounting bolt B (see FIGS. 2 and 3) is tightened and attached from a long hole 5a to a lower portion on the inner surface side of the wall panel P. The side end of P is positioned so that it is attached to the lower corner of the wall panel P. The lower metal piece 5 has an h-shaped side view in which a locking piece 6 is projected, and a nut N to which a height adjusting bolt HB is screwed is joined to the outer surface of the locking piece 6. In the illustrated example, the lower metal piece 5 has a flat plate substrate 51 and a lightning plate 61 joined thereto. However, a part of one flat plate is cut and raised to form the locking piece 6. May be

Reference numeral 7 is an upper metal fitting to which a mounting bolt B (see FIGS. 2 and 3) is tightened from the elongated hole 7a and attached to the upper portion on the inner surface side of the wall panel P. In the example shown in FIG. It is designed to be attached to the upper corner portion of the wall panel P 1. In this upper metal piece 7, a locking piece 8 is projected in an inverted h shape in side view so that the lower metal piece 5 is turned upside down when used. The upper metal 7 has a shape in which the height adjusting bolt HB and the nut N are omitted from the lower metal 5, thereby making it possible to reduce the manufacturing cost by using the same basic configuration.

In the structure as described above, when mounting the wall panel P, first, the base metal 2 is joined by welding or the like to a predetermined position of the steel column 1 corresponding to the mounting position of the wall panel P. Next, the ruler angle 3 is joined to the upper surface of the horizontal piece 2a of the base metal 2 by welding or the like while adjusting the entrance / exit of the steel pillar 1 or the like. Further, a ruler angle 4 corresponding to the ruler angle 3 is joined to the lower surface of the horizontal piece 2a of the base metal member 2 by welding or the like in which the entrance / exit is adjusted.

In this case, loose holes are provided in both the ruler angles 3 and 4 and the base metal 2, and bolts are inserted through these to temporarily fix and fix them, and as a positioning finish after adjustment attachment of the wall panel P described later and attachment. They may be welded, which improves the workability of mounting the wall panel when adjustment of construction errors is likely to occur.

Next, the lower metal piece 5 and the upper metal piece 7 are attached to the predetermined positions on the inner surface lower side and the upper side of the wall panel P by the mounting bolts B. In this case, the lower metal 5 is tightened by finely adjusting the attachment level to the wall panel P by the elongated hole 5a. The upper metal 7 is lowered to the lower level defined by the long hole 7a without tightening the mounting bolt B. In this case, it is more convenient if the mounting bolt B is attached to only one of the two elongated holes 7a so that the upper metal member 7 can rotate.

After the above setting, the wall panel P is suspended by a crane or the like, and the lower metal piece 5 is engaged with the standing piece 3 a of the predetermined ruler angle 3 of the steel column 1 by the locking piece 6. Next, the upper side of the wall panel P is brought close to the steel frame pillar 1, and the upper metal 7 is rotated with respect to the standing piece 4a of the lower ruler angle 4 of the base metal fitting 2 to engage the locking piece 8 with the standing piece 4a. Let In this case, the elongated hole 7a of the upper metal 7 is used to vertically adjust the degree of engagement of the metal with the vertical piece 4a to tighten the mounting bolt B. In order to align the joints of the adjacent wall panels P with each other. Since the panel level is finely adjusted by the height adjusting bolt HB of the lower metal 5, the upper metal 7 is tightened in consideration of the fine adjustment vertical amount.

After the above work, in order to prevent inadvertent displacement and loosening of the lower metal piece 5 and to prevent inadvertent loosening of the upper metal piece 7, the necessary parts are fixed by welding. .. For example, as shown in FIG. 3, in the lower hardware 5, the mounting bolt B is prevented from loosening, the ruler angle 3 and the metal engaging piece 6 are fixed at the abutting position, the height adjusting bolt HB is prevented from loosening, etc. In the upper metal 7, the mounting bolt B is prevented from loosening.

In the above-mentioned mounting work, at the position where the upper and lower wall panels P, P are adjacent to each other, the lower side and the upper side of the upper and lower wall panels are shared by one frame side metal fitting of the steel column 1. Since the work places are concentrated, the work is excellent in convenience. Further, since the metal parts on the lower side and the upper part on the lower side are not attached to the individual metal parts on the body side as in the prior art, they are commonly used, which is advantageous in terms of material cost.

Further, according to the above-mentioned mounting structure, when a horizontal force due to an earthquake is applied, the lower part of the wall panel P moves following the horizontal displacement of the steel frame column 1, but the upper part of the wall panel mounts the upper metal part 7. Since it is not fixed to the ruler angle 4, it can be moved relative to the steel frame column 1 in the end, so that the wall panel P can be prevented from being damaged without being applied with an excessive displacement force.

[0020]

[Effect of the device]

 As explained in detail above, according to the mounting structure of the present invention, the relative movement amount of the upper metal piece with respect to the horizontal force due to an earthquake is not mechanically restricted as in the conventional case, so that it depends on the set length of the ruler angle. It is possible to fully respond to an earthquake. In addition, since the work of attaching the wall panel is performed by sharing one metal member on the body side at a position where the upper and lower wall panels are adjacent to each other, the work is easy and the material cost is advantageous.
