Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an insulation structure between a wall and a frame such as a column.

(Prior Art) In an RC structure, the walls that exist within the frame are greatly involved in earthquake resistance. There is no problem if it functions effectively as a seismic wall, but if the walls are unevenly distributed or if there is a waist wall or a side wall, which is said to be a male type, twisting and stress concentration will occur in the building, and the rigidity balance of the entire building will be affected. The earthquake resistance will be significantly reduced.

In order to prevent such inconveniences, in the past, walls were made of PC or non-concrete instead of integrally cast walls, and furthermore, ready-made slit sealing materials were used to separate the walls from the frame.

(Problems to be Solved by the Invention) According to the conventional example, using a PC wall board, a non-concrete wall board, or a slit sealing material specifically for edge cutting leads to an increase in cost.

An object of the present invention is to provide a structure that can reliably and inexpensively insulate between a wall and a frame.

(Means for Solving the Problems) The present invention embeds a cushioning material 7 in one of the wall 3 and the frame 1, 2.2a, and embeds one end side of the connecting body 4 in the other. The connecting body has one end projecting in one direction, and the other end of the connecting body is inserted into the cushioning material.

(Function) When the building moves horizontally during an earthquake, the connecting body 4 attached to one of the walls 3 or frames 1, 2, 2a is connected via the cushioning material 7 provided on the other side, so there is no possibility of inter-story displacement. It becomes possible to follow.

(Example) In Figures 1 and 2, on both sides of the lower part of the wall plate 3 built in the pillars 1 and beams 2, 2a constituting the frame, there are dowel bars 4 that protrude from the outer surface of the pillars and serve as connecting bodies. The tip is inserted. At the bottom of both sides of the wall board 3, anchor metal fittings 5 in the shape of a letter 6 are installed at the corner A part, as shown in an enlarged view in FIG.
This anchor fitting has elongated holes 5a that extend upward and downward, and the dowels 4 pass through these holes. It has a width and length that can be moved up and down.Inside the anchor fitting 5,
A cushion material 7 made of foamed styrene or the like is provided which communicates with the elongated hole 5a and has an insertion hole 7a inside. The distance R between the bottom of the insertion hole and the end face is such that it can follow the interlayer displacement between the beams 2, 2a and the column 1. Inserts 8 are embedded in the lower surfaces of both sides of the wall plate 3, and adjuster bolts 9 which also serve as wall plate supports are screwed into these inserts. The head of the bolt 9 is in contact with an iron plate 10 attached to the beam 2a. By turning the bolts 9, the vertical position of the wall plate 3 can be adjusted.

In addition, the fitting of the B part and C part of the first illustration of the wall board 3 will be explained.

At section B, the roots 11 are attached to the outer surface of the wall board 3 via anchor bars 12, as shown in FIG. For this installation, a stud bolt 13 is provided protruding from the outer surface of the plate, and this bolt is installed on the joint plate 1 which is erected above the beam 2a.
4 through the elongated hole 14a. The elongated hole is long in the horizontal direction and has a length and width that allow the bolt 13 to move in the horizontal direction.

In section C, as shown in FIGS. 4 and 5, a groove 3a is provided on the outer surface of the upper end of the wall plate 3, and a mounting plate 15 is exposed in the groove. It sticks to. Attachment (A joint plate 17 is fixed to the plate 15 in a superposed state. This joint plate 17 is fixed to a retaining plate 18 that protrudes from the lower surface of the upper beam 2. The base of the retaining plate 18 is attached to an anchor. It is fixed to the beam 2 via a reinforcement 19.

Next, we will explain the construction procedure for the wall.

In advance, as shown in Figure 6, plywood, sheets, etc. are laid on the already completed slab 20, and the surrounding formwork is set.
Wall board 3 is made by arranging reinforcement and pouring concrete 1 to 3.

At this time, a release agent is applied to the dowels 4 that have been driven into the pillars 1 in advance, and this is inserted into the holes 7a of the cushion material 7 of the wall board 3.

In this way, PC wallboards are manufactured on-site.

First, when the concrete reaches a predetermined strength, the wall plate is rotated upward (in the direction of the arrow in FIGS. 2 and 6) using the dowel reinforcements 4 as hinges, and is placed in the position shown by the solid line in FIG. after that,
Turn adjuster bolt 9 to adjust the height, and then
, the joint plate 17 at portion C is joined to the retaining plates of the upper and lower beams.

As a means for rotating the wall plate 3, a light pipe 4-cliff l~
Select a method such as lifting the end of the wall board using a rope or lifting it from above using a rope and a pulley attached to the upper beam.

In this example, P is commercialized to improve the performance of shear walls.
Since the on-site installation uses a cast-in-place PC wall that can be manufactured on-site without using a C board, the manufacturing cost 1~ becomes inexpensive.

Depending on the shape of the wall, it is possible to attach windows 21 (Fig. 1), sashes, and tiles, making scaffolding unnecessary.

Other examples will be explained with reference to FIGS. 7-9.

In this example, the edges of the wall plate 3 and the beam 2 are cut, but this structure is substantially the same as the upper side, and corresponding parts are given the same reference numerals.

Note that the dowel bars 4 are provided protruding from the top of the wall board 3 and are higher than the back of the beam 2. The cushioning material 7 is sandwiched between U-shaped reinforcing bars 22 to integrate the cushioning material 7 and the concrete of the wall board.

The construction of this example will be explained.

A construction method will be adopted in which concrete is poured separately for walls 3 and beams 2.

First of all, when pouring the concrete for the wall, at the top of the wall -〇　- The anchor fitting 5 is embedded together with the cushion material 7.

When reinforcing the beam, the dowel reinforcement 4 is inserted into the center of the elongated hole 5a of the anchor fitting 5 to stand up above the wall board. After pouring concrete for the beams, mortar 23 is laid on the lower part of the upper wall.

Then, a release agent is applied to the upper end of the dowel 4 protruding from the beam 2, and the anchor fitting 24 is inserted from the upper end. After placing the wall reinforcement, pour the wall concrete.

In this example, a wall with the same performance as a PC wall board can be made on-site at a low cost without converting the wall to PC.

On each of the above sides, if reinforcing bars are used as the connecting body,
Although the structure is simpler, a plate may also be used.

(Effects of the Invention) According to the present invention, since a connecting body and a cushioning material are interposed between the wall and the frame, interlayer displacement can be reliably followed at low cost with a simple configuration, and excellent earthquake resistance can be achieved without adversely affecting the frame. You can get the wall.
