Description

[Detailed description of the invention] Industrial application field The present invention relates to a PC board mounting device for attaching a PC board to an external wall.

Prior Art In the past, PC boards were often attached directly onto beams, which made it difficult to attach the PC board over the joints of the beams. In addition, most of the mounting hardware is of the concrete jaw type, and the hardware for receiving the load and for retaining the inside and outside of the surface are often attached to the PC board separately, and the embedded parts (concrete jaws) and hardware are attached to the finished surface of the floor. In most cases, it was higher.

Problems that the invention aims to solve: The cost of mounting hardware is high;
It was difficult to keep the tips of the load-bearing concrete jaws within the height of the floor, and it was also difficult to attach PC boards to joints of beams and the like. Also, JP-A-61-
The dowel pin method shown in No. 75148, which is commonly called the dowel pin method, has dowel pins embedded in the PC board, and there are many errors in the pin embedding position, and as a result, it is necessary to smooth the outer edges of the upper and lower PC boards. is extremely difficult.

Means for Solving the Problems Taking these points into consideration, the inventor of the present invention repeatedly made various prototypes and conducted experiments, and as a result, provided a protrusion 4a on the T-shaped metal fitting 4 embedded in the PC board panel 5. This protrusion 4a is provided with a loose hole 4b and an adjustable bolt 8 that is screwed through the protrusion 4a, while the L-shaped metal fitting 2 whose lower end is welded to the upper part of one end of the beam 1 is provided with an upper edge thereof. The pin 3 is fixed to a part of the load receiving adjustable bolt 8.
The pins 3 are inserted into the loose holes 4b of the projections 4a to adjust the inner and outer surfaces, and the load receiving adjustable bolts 8 are used to adjust the upper and lower parts of the PC board panel 5. The washer 6, which is inserted into the pin 3 after adjusting its direction, is welded to the protrusion 4a.

Function Therefore, since the PC board panel is hung using the L-shaped hardware 2 to which the pin 3 is attached in the front, the safety when installing the PC board panel is very high, and one end of the pin 3 The surface of the PC board is below the finished surface of the floor, finishing the back side of the PC board panel is very simple and economical, and the PC board can be installed regardless of the joints of beams, etc., making it easy to install. Furthermore, in the present invention, even on the joints of the beam 1, L
Since the mold metal 2 can be installed, it is possible to mount the PC board even on the beam joint.

Embodiment The present invention will be explained according to the embodiment shown in the figure.
The figure is a front cross-sectional view of the main part centered on pin 3,
The figure is a front view centered on the load-receiving adjustable bolt 8, in which 1 is a beam, and the lower end of the L-shaped metal fitting 2 is fixed to one end of the beam by welding so as to be at an appropriate height above the beam 1. . By floating the PC board attachment part a certain height above the beam 1 in this way, the PC board can be attached to the beam regardless of the joints of the beams, etc. Even if it is in a floating state, the stability is good because the rib plate 7 is included. Reference numeral 3 denotes a retaining pin on the inside and outside of the surface, and a bolt with a thread cut on the upper part can be used, and this is fixed to the L-shaped metal fitting 2 from the beginning. 4 is a T-shaped embedded metal fitting that is embedded in the PC board panel. The T-shaped embedded metal fitting 4 is a protrusion 4
The pin 3 is passed through a through hole 4b provided in a part of the protrusion 4a, and is welded to the protrusion 4a of the embedded metal part 4 with a washer 6. In actual use, it is preferable to use an eccentric washer 6 in consideration of misalignment during installation. Also, as shown in Figures 2 and 3, the load bearing adjustable bolts 8 of the PC board panel are arranged in line behind the pins 3 in Figure 1.
After adjusting the vertical position of the plate panel 5, it is fixed by welding. Note that 7 is a reinforcing rib of the L-shaped metal fitting 2.

Effects of the invention As described above, in this invention, since the L-shaped metal fitting 2 can be installed even on the beam 1, it is possible to install the PC board panel even on the beam welded part, and it is also possible to install the PC board panel on the beam welded part. A pin 3 is fixed to the L-shaped metal fitting 2. After hooking the loose hole 4b of the T-shaped metal fitting 4 embedded in the PC board panel 5 and adjusting the surface inside and outside, the pin 3 and Adjust the PC board panel 5 in the vertical direction using load receiving adjustable bolts 8 provided on the protrusion 4a of the PC board 4 in parallel, and later weld the washer 6 to the protrusion 4a of the T-shaped metal fitting 4. Since the PC board is fixed in place, the PC board can always be mounted in a predetermined position both inside and outside the surface as well as in the height direction. The structure is simple, and the lifting of the PC board follows the displacement between the building's floors using a locking method (rotation type), making it inexpensive.

[Brief explanation of the drawing]

FIG. 1 is a front sectional view of the main parts centering on the pin 3, FIG. 2 is a front view of the same centering on the load receiving adjustable bolt 8, and FIG. 3 is a side sectional view of the same. In the figure, 1 is a beam, 2 is an L-shaped metal fitting, 3 is a retaining pin inside and outside the surface, 4 is a T-shaped embedded metal fitting, 4a is a protrusion of the T-shaped embedded metal fitting, 4b is the same loose hole, and 5 is a
PC board panel, 6 is washer, 7 is reinforcing rib, 8
is an adjustable load-bearing bolt.
