Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a tiled PC board that constitutes the outer wall side of a concrete outer wall of a building.

(Prior art) In recent years, tiles have been increasingly used on exterior walls to improve the aesthetic appearance of buildings, but there are problems such as peeling of the tiles, and to solve this problem There are many cases where a PC board is used. An example of this type of PC board is the one disclosed in Japanese Patent Publication No. 54-31293. The PC board in this example consists of a PC board main body and a fixing reinforcing bar, and this reinforcing bar is a combination of chord members located above and below and connecting reinforcing bars that connect the chord members. The lower chord consists of two reinforcing bars arranged in parallel, which are buried inside the PC board body, and the connecting reinforcing bars are a number of inverted V-shaped reinforcing bars, and the base of each reinforcing bar is composed of two lower chord bars. Each piece is welded to the material, and the top part is fixed to a single upper chord member.

(Problems to be Solved by the Invention) According to the above, inverted V-shaped reinforcing bars, which are independent items, must be sequentially arranged at intervals on each of the two chord members, and the reinforcing bars Since it is necessary to weld the anchorage reinforcing bars to the upper chord at an angle, there is still room for further improvement in order to increase the efficiency of the reinforcement work for anchoring reinforcing bars. Also, as a general issue, P
Before pouring concrete inside the PC board with the C board installed, the position of the PC board must be adjusted, and the challenge was to make the adjustment work easier.

(Means for solving the problem) The tile driven PC board 1 of the present invention has a front surface as a tile driven surface, and a parallel chord truss 2 exposed on the back side.

The parallel chord truss 2 is a combination of chord members 21 and 22 located in parallel and a truss-shaped belly member 23 that connects both chord members. Both chord members 21 and 22 consist of a pair of string members 21a and 21b, 22m and 22b, which are located in parallel, respectively, and each pair of arc members is connected to a connecting plate 24, 24a at a plurality of points.
, and the belly member 23 is connected to the chord members 21.22 via the connecting plate 24.24a. One of the chord members 21 is connected to the PC board 1.
The other string member 22 is embedded in the PC board, and the other string member 22 is exposed to the back side of the PC board. Then, on the back side of the PC board 1, there is a holding bolt 8 that holds the PC board 1 on the beam 10 and adjusts the position of the PC board, and a connection that connects with the other chord member 22 of the PC board located below and also serves for position adjustment. (Embodiment) An embodiment of the present invention will be described below based on the drawings. As shown in FIGS. 1 to 3, the PC board 1 has parallel chord truss 2. In the illustrated example, the truss is arranged vertically on both sides of the opening 110 of the PC board, and the lower chord member 21 of this truss
are buried inside the PCC circle, and the upper and lower chord members 21 and 22, both of which are exposed on the back surface of the plate, are fixed in parallel with a truss-shaped belly member 23 at a predetermined interval. Both strings 21.
Reference numeral 22 indicates two string members 21m, 21b and 22a, which are located parallel to each other in the horizontal direction, as shown in FIG. 4.5.

The pair of arc members 21a and 21b, 22a and 22b are connected at a plurality of locations by bands 24 and 24a, which are connecting plates made of band plates. band 2
4.24a are arranged alternately or staggered. The top of the belly member 23 is fixed to the band 24.24a by welding, thereby connecting and fixing both chord members 21 and 22. 3 is P
The tiles are placed on the front side of the C board 1, and this front side is the tile driving surface.

In addition, an insert 5 is buried in the lower part of the PCC circle with its opening facing outward from the back, and the rear end of the connecting bolt 6 is screwed into this insert, and this bolt is horizontally extended outward from the back of the PC board. It is a protruding structure.

As shown in Fig. 1.2.5, two connecting plates 7.7 are attached to the threaded portion at the tip of the connecting bolt 6, and nuts 6a, 6a are located on the outside of these connecting plates. There is. Both coupling plates 7

The upper end of 2b can be held. 22a of the upper chord member,
A connecting plate 24b that is substantially the same as the connecting plate 24a is attached to the upper end of the connecting plate 22b, as shown in Fig. 1.2.6, and a holding bolt 8 is inserted from the center of the connecting plate 24b to the PC board. 1
0 holding bolt 8 that protrudes horizontally on the opposite side (right side)
8a + 8a is the installation. As shown in FIG. 2, the tip of the holding bolt 8 passes through a mounting hole 9a in the vertical part of a holding member 9 made of an angle material and fixed to the upper surface of the flange of the beam steel frame 10& of the beam 10. The holding bolt 8 is fixed to the holding member 9 by holding the vertical portion of the holding member 9 with both nuts 8a. The mounting hole 9a is a loose hole that is long in the direction perpendicular to the plane of the paper in the second drawing, and allows the position of the holding bolt to be adjusted in the vertical direction (lateral direction of the PC board).

It has substantially the same configuration as the last. The holding bolt may be provided depending on the placement position.

Next, how to use it will be explained.

First, install the PC board 1 on the outer wall side with the tile driving surface facing outward, insert the tip of the retaining bolt 8 into the mounting hole 9a of the retaining member 9, and tighten the PC board 8a r 8a'i. Retaining bolts and retaining members and beam steel frame 10
Next, fix the upper part of the upper PC board 1a (Fig. 2) to the beam steel frame, and connect the connecting plate 7 of the lower connecting bolt 6,
Upper chord members 22a, 22 of PC board 1 located below 7
The upper and lower PC boards 1 and 1a are connected by clamping them with b and fixing the clamped parts with nuts 6a and 6a. After that, wall reinforcements 4 + 4 a (Fig. 2) are arranged on the back sides of the PC boards 1 and 1a, an inner formwork is assembled at a predetermined distance from the wall reinforcements, and the PC boards and this formwork are assembled. Place concrete in between.

Here, the adjustment work for the installation position of the PC board 1.18 will be explained.

Adjustment of the PC board 1 in the longitudinal direction (left and right in FIG. 2) is performed by moving the holding bolt 8 back and forth around the holding member 9.

For horizontal adjustment, insert the holding bolt 8 into the mounting hole 9 of the holding member.
This is done by moving the area within a in a direction perpendicular to the plane of the second drawing. The lower side of the PC board 1 is adjusted by moving the connecting bolt 6 back and forth or left and right. The PC board 1a is also adjusted in the same manner.

As explained above, according to the present invention, the string members of the parallel string truss that are attached to the PC board are each composed of paired string members, and the belly member is fixed to the connecting plate that connects the arc members. As a result, assembly efficiency can be improved compared to conventional examples, and connection between PC boards during use becomes easier.Furthermore, the rigidity of the truss bars is higher than that of conventional ones, making it easier to remove the boards when manufacturing PC boards. 0 and the position of the PC board can be easily adjusted.
