Description

  The present invention relates to a panel member mounting structure when a panel member is attached to a pillar / beam material of a building frame as in the curtain wall method.

  Columns and beams that form the building's frame are composed of reinforcing bars, steel concrete, steel frames, etc., and vertically long panel members that are manufactured by attaching the mounting members etc. in advance at the factory, etc., in advance using appropriate mounting means. Installation (In the installation of the outer wall material, panel members are arranged side by side in sequence, and the lower part of the panel member is placed on top of the panel members arranged in the horizontal direction and stacked.) There are many curtain wall construction methods. The vertical panel members used in this construction method are manufactured in advance in the factory, so the panel members have a uniform quality and good aesthetics, especially when this vertical panel member is used as an outer wall material, weather resistance, construction It has received high evaluation in terms of sexuality and aesthetics, and mounting frames, mounting members to pillars and beams are pre-installed at the time of production at the factory, and openings are also created in advance, so it has been built at the construction site. The curtain wall construction method is often adopted from the viewpoint that the workability is good and the construction period can be shortened.

  A panel member mounting structure of the curtain wall method for mounting a panel member as an outer wall material to a built column or beam will be described with reference to FIGS. A rebar / steel concrete and a pillar 60 such as a steel frame and a beam 61 form a frame that is a building frame, and a deck plate flooring 62 is placed on the beam 61 to form a floor. An appropriate number of outer wall members 63 are attached to the beam 61 by means of attaching means such as bolts (see the description of “Non-Patent Document 1”).

  Various attachment means have been proposed as means for attaching the outer wall material to the beam or the floor slab. As described with reference to the conventional example of FIG. 11, the PC plate 69 serving as the outer wall material is a concrete flat plate attached to the steel beam 64. The fastener 72 is fixed by a bolt. The steel beam 64 is an H-shaped steel made up of an upper flange 68, a web, and a lower flange, and a piece 70 that is paired with the fastener 72 is fixed to the upper flange 68. A flat deck receiving material 67 is attached to the web, and a flat deck 66 is laid on the flat deck receiving material 67. The floor slab concrete 65 is a concrete slab placed on a flat deck 66 laid on a flat deck receiving member 67 of a steel beam 64.

  The flat deck 66 is a deck plate that is laid on a flat deck receiving member 67 of the steel beam 64 and on which floor slab concrete 65 is placed. The fastener 72 is an L-shaped mounting bracket used to secure the mounting accuracy of the PC board 69 and to absorb the stress generated by deformation of structures such as beams and slabs, and is fixed to the PC board 69 with bolts. . Further, the fastener 72 has a hole 73, and the PC plate 69 is attached when the pin 71 of the receiving piece 70 fixed to the steel beam 64 passes through the hole 73 (“Patent Document 1”). See description).

  In attaching the PC plate to the steel beam described in “Patent Document 1”, a piece having a mounting pin is fixed to the upper flange of the steel beam at a position corresponding to the hole of the fastener attached to the PC plate. These pins are fixedly attached through the holes of fasteners attached to the PC board. However, at the construction site, it is necessary to adjust the mounting position slightly (up / down / left / right / depth adjustment), but simply by passing the pin of the piece through the hole in the fastener attached to the PC board. The position cannot be adjusted.

  In order to adjust the mounting position, an L-shaped mounting bracket 75 and a hat-shaped mounting bracket 76 that can be mounted and adjusted with each other are mounted on the steel beam and the outer wall material, respectively, and are mounted on the steel beam or floor slab. In the mounting bracket 75, a long hole 83 is formed in a contact surface portion 82a that contacts a surface of the steel beam and a contact surface portion 82c of a hat-shaped mounting bracket 76, which will be described later, and a contact surface that contacts the steel beam. A long hole 84 is provided in each of the surface portions 82b, and a hat-shaped mounting bracket 76 to be attached to the outer wall member has mounting pieces 78 and 78 on the top and bottom, and a contact surface portion 82a of the L-shaped mounting bracket 75 in the center. The contact surface portion 82c is provided with a long hole 80 orthogonal to the long hole 83 provided in the contact surface portion 82a of the L-shaped mounting bracket 75 (see FIG. (See FIGS. 12 and 13).

  Then, the L-shaped mounting bracket 75 is mounted on the steel beam or the floor slab with a bolt (not shown) through the long hole 84 of the L-shaped mounting bracket 75, while the hat-shaped mounting bracket 76 is mounted on the upper and lower sides with a bolt (not shown). The outer wall material to which the pieces 78 and 78 are attached is weighted by an appropriate weighting device, and the hat-shaped mounting bracket 76 of the outer wall material is brought close to the L-shaped mounting bracket 75 of the trabecular or floor slab, After aligning the front and rear, left and right, and top and bottom of both, the bolt 86 is inserted into the long hole 83 of the L-shaped mounting bracket 75 and the long hole 80 of the hat-shaped mounting bracket 76, and the both are stopped with a nut.

  However, if the L-shaped mounting bracket 75 attached to the steel beam or floor slab and the hat-shaped mounting bracket 76 attached to the outer wall material are fastened with frictional force by bolts and nuts, the building can be used over time. When an earthquake or vibration is applied, bolts and nuts may loosen. Then, a gap is formed in the joint portion between the adjacent outer wall materials, and rainwater enters the inside from this portion, and the pillars and beams constituting the framework of the building frame are corroded.

  For this reason, not only fastening with bolts and nuts, but as an additional fixing means, after adjusting the lateral mounting position by contacting the side end of the new outer wall material to the side end of the existing outer wall material, The outer wall material hat-shaped mounting bracket 76 and the trabecular L-shaped mounting bracket 75 are temporarily fixed with bolts and nuts. Then, marking for drilling is performed on the contact surface portion 82c of the hat-shaped mounting bracket 76 in accordance with the position of the hole 85 previously formed in the contact surface portion 82a of the L-shaped mounting bracket 75.

  Then, after marking for drilling, the temporary fixing is once removed, and the part marked for drilling the contact surface portion 82c of the hat-shaped mounting bracket 76 is drilled at the construction site by a welding machine. do. Then, the L-shaped mounting bracket 75 of the trabecular bone or floor slab and the hat-shaped mounting bracket 76 of the outer wall material are aligned in the front-rear, left-right, and vertical directions, and then fastened with bolts 86 and nuts. A bolt 87 is inserted into a hole 85 of the mold mounting bracket 75 and a hole formed in the hat-shaped mounting bracket 76 by a welding machine and fastened with a bolt and a nut.

In this way, temporary fixing work with bolts and nuts between the L-shaped mounting bracket 75 of the trabecular bone and the hat-shaped mounting bracket 76 of the outer wall material, marking work for drilling at the construction site, and temporary fixing are released. After that, many operations are required, such as drilling the mounting bracket, positioning again and fastening with bolts and nuts, and fastening with bolts and nuts. In addition, since the mounting bracket for drilling has a thickness that can withstand the mounting of the outer wall material, the drilling operation at this construction site is particularly a time-consuming and labor-intensive task. ing.
