Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a joint fitting that connects the upper end of a concrete panel erected near the pillars of a house to a mounting fitting that connects the pillar and the beam. The present invention relates to a concrete panel mounting structure that can streamline the mounting work by using concrete panels.

[Conventional technology]

BACKGROUND ART In recent years, concrete exterior wall panels are often used to increase fire resistance and sound insulation when forming walls such as exterior walls of houses. Also, for such exterior wall panels,
In order to increase the living area and make effective use of the site, they are often placed outside, such as on beams.

[Problem to be solved by the invention]

However, such exterior wall panels, especially concrete panels made of concrete, are heavier than regular wall panels with side panels attached to the front and back of the framework, so it takes a lot of effort to attach them to the outside of beams, etc. In addition, there is a problem that the safety of the installation work and the accuracy of the installation are inferior.

Therefore, it is easy to install heavy exterior wall panels,
There has been a demand for a structure that can improve assembly accuracy and safety.

The present invention is based on attaching the upper part of a concrete panel using a connecting plate interposed between a beam material and a mounting bracket that connects the beam material to a column, and fixes the concrete panel by protruding from the outer surface of the column. Our objective is to provide a concrete panel mounting structure that can be used to improve construction efficiency and installation accuracy.

[Means to solve the problem]

In order to achieve the above object, the concrete panel mounting structure of the present invention includes a 1L mounting bracket having seven connecting pieces extending perpendicularly and horizontally to the one side, on one side of a column made of square steel pipes, and a lower one. A lower surface of a beam member having a connecting piece fixed thereto below, the end of which is inserted between the upper connecting piece and the lower connecting piece, and which is perpendicular to the one side surface; A connecting plate having a protruding portion protruding toward the outdoors is interposed between the upper surface of the lower connecting piece, the upper and lower connecting pieces are bolted to the beam, and the connecting plate is disposed outside of the beam. A connecting fitting having hanging pieces on the inside and outside of the base piece is attached to the upper inner surface of the concrete panel forming the outer wall by bolting the outer hanging pieces, and the connecting fitting and the overhanging part are attached to the concrete panel by bolting the outer hanging pieces. an upper piece that is bolted to the lower surface of the overhang, an outer piece that hangs down at its outer edge, a lower piece that faces inward at its lower edge, and an inner piece that hangs down at the inner end of the lower piece. They are connected via a joint having a connecting piece that is bolted to the piece.

[Effect]

A connecting plate is interposed between the connecting piece of the lower mounting bracket fixed to one side of the column and the beam material, and has an overhang that projects outdoors and allows a concrete panel to be attached.
The lower connecting piece is bolted to the beam. Therefore, the connecting plate can be firmly attached. In addition, the connecting plate for concrete panel installation can be bolted together at the same time as the beam material is attached to the column, reducing the number of work hours.

Further, the overhanging portion and the connecting fittings bolted to the concrete panel are connected by bolting to the joint fittings, respectively. By bolting all the members for removing the exterior wall panels in this way, it is possible to improve work efficiency and installation accuracy by simplifying the work, and
It also helps improve safety.

Further, the joint fitting 15 and the connecting fitting 14 are firmly fixed by a bolt passing through a hole provided in the connecting piece 57 of the fitting 15 and a through hole drilled in the hanging piece 39 in the core. Ru.

As a result, the upper part of the concrete panel 16 is connected and fixed to the beam 9, and the lower part is connected to the panel support fitting 41, which is fixed to the bolt installed in the cloth foundation A, via the connecting member 49. Supported.

As shown in FIGS. 2 to 4, the connecting member 49 is a channel-shaped member having a groove portion formed by an inner piece 51 and an outer piece 52 rising from the inner and outer edges of a long horizontal receiving piece 50, respectively. and the receiving piece 5
A pair of elongated holes 53 and 53 extending in the longitudinal direction are bored in the hole 0 . Further, the lower bolt 31 is attached to the outer piece 52.
Bolt holes are provided through the holes corresponding to the positions -, , , -. By inserting the bolt 31-1 under the concrete panel 16 into the bolt hole and tightening the nut, the connecting member 4
9 is fixed to the concrete panel 16.

The panel holder 41 has a base body in which a vertical piece 43 is raised from the outer edge of a horizontal piece 42 that is placed on the cloth foundation A and bolted. A pair of nut pieces 44.44 having holes and a pair of boss pieces 45.45 having vertical screw holes are attached.

The nut piece 44 has a support bolt 46 having a head at the upper end.
is screwed perpendicularly to the advance/retreat mark. As the support bolt 46 rises, its upper end comes into contact with the lower surface of the receiving piece 50 of the connecting member 49, supporting its lower end.

Further, a bolt 47 is inserted into the screw hole of the boss piece 45 through the long hole 53 provided in the receiving piece 50, and has a head larger than the width of the long hole 53 above. Hole 53
is inserted through the receiving piece 50 and protrudes upward from the receiving piece 50. As a result, the lower part of the concrete panel 16 can be moved laterally by the length of the elongated hole 53, and the bolt 4
It becomes possible to move in the vertical direction by a protrusion of 7. Therefore, even if the beam 9 moves horizontally and vertically when an earthquake occurs,
Breakage of the concrete panel 16 can be prevented without applying any straining force to the concrete panel 16.

Note that the concrete panel 19 is attached in the same manner as the concrete panel 16 with the pillar 2 in between.

Further, above the concrete panels 16 and 19, as shown by the dashed line in FIG. The lower inner surface is supported using the material 49 and the panel holder 41.
