Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a joint device that is installed across walls of adjacent buildings.

Conventionally, in order to absorb the deformation of the building caused by expansion and contraction of the building wall, seismic vibration, uneven settlement, etc., a joint has a structure that forms a certain gap in the wall and can deform and absorb this gap. It is blocked using a device.

However, conventional coupling devices have complicated structures,
Moreover, since the deformation absorption performance in the vertical and horizontal directions is not sufficient, it is often impossible to adapt to the deformation, and there is a problem in that the above-mentioned gap cannot be completely closed.

In view of these problems with conventional devices, the present invention has a simple structure and high deformation absorption performance.
Moreover, even if there is a difference in the degree of expansion between the two parallel walls due to external conditions, or if there is a partial difference in expansion in the length direction of each wall, this can be ensured. With the aim of providing a joint device that can be absorbed by

That is, the device of the present invention includes a substrate section that is attached to the upper surface of each adjacent wall body at appropriate intervals while maintaining a gap that has a flow gradient and opens above the upper surface of the wall body toward the other wall body. , a draining plate formed by a rising part protruding from the upper side of the base plate and a hanging part protruding from the lower side is installed with both rising parts facing each other with a gap between them, and the upper and lower joints are attached. The plate is interposed between both joint plates, with the upper joint plate being positioned at the rising part of both sides, and the lower joint plate being housed in the gap between the upper surface of the wall and the base part of the draining plate. It is characterized in that it is connected by a tension spring so that both joint plates sandwich and hold the drain plate, and a cover material is attached to the upper joint plate to close off the space between the two walls.

The present invention will be described below with reference to illustrated embodiments.

The walls 1, 1 according to the embodiment shown in FIG. 1 are rising walls of a concrete roof, and each wall body 1, 1
Draining plates 7, 7 are attached to the upper surface of the drain plate. Each of the drain plates 7, 7 is formed of an extruded section having the same cross-sectional shape, and the base portion 7 has a flow gradient.
A rising portion 7d is continuously provided at the upper end of c, and a hanging portion 7e is continuously provided at the lower end, and a locking protrusion 7 for attachment and fixation is provided on the back surface of the upper end side and the back surface of the hanging portion.
a and 7b.

Each draining plate 7, 7 is connected to the upper surface of each wall body 1, 1.
A certain gap is formed with the fixing fittings 4, 4 interposed,
The respective rising portions 7d,
7d is in the opposite state.

The fixing fittings 4, 4 have a locking claw portion 4a that locks on the locking protrusion 7a of the draining plates 7, 7 on one side of the base 4c which abuts and overlaps the upper surface of the walls 1, 1, and a locking claw portion 4a on the other side. It consists of a locking claw part 4b that locks on the locking protrusion 7b, and when fixing to the upper surface of the walls 1, 1, the water guide plates 3, 3 and both walls While holding down the water stop plate 2 that spans between 1 and 1, insert the anchor bolt 5,
5.

Incidentally, drain ports 6, 6 with backflow prevention valves are provided at the lower ends of the water guide plates 3, 3.

As mentioned above, in order to close the gap between the draining plates 7, 7 facing each other at a constant interval, a cover material 8 is provided spanning each draining plate 7, 7, but in order to attach this cover material 8, A pair of upper and lower joint plates 10 and 12 are used.

The upper joint plate 10 is made up of a wing plate 11 with a screw-mounting recess 11a in the center, and leg pieces 11b, 11b hanging in a slightly inclined manner on both sides of the wing plate 11, and the lower joint plate 12 has a screw-mounting recess 11a in the center. It is made of a plate-shaped body having a recessed portion 12a.

Both joint plates 10, 12 are connected by a coiled tension spring 15 interposed therebetween, and the connection is achieved by screws 13, 14 inserted into respective screw mounting recesses 11a, 12a.
The shaft portions 13a, 14a of the two are facing each other as shown in FIG. The plates 10, 12 are in a state of being drawn toward each other and can be separated against the tension of the tension spring 15.

The upper and lower joint plates 10, 12 connected in this way have their respective side portions connected to the drain plates 7, 7.
The upper joint plate 10 straddles each drain plate 7 in a superposed state and holds them together.
The lower joint plate 12 is in contact with the rear surface locking protrusions 7b, 7b. The upper and lower joint plates 10 and 12 are mounted at positions where they do not interfere with the fixing fittings 4 and 4.

The cover material 8 attached to the upper joint plate 10 has downward hanging walls 8b, 8 on both sides of the board.
b are arranged in a row, and tight material fitting grooves 8c, 8c are bulged out at the lower end of each hanging wall 8b, 8b, and the fitting is done by connecting the bulging tight material fitting grooves 8c, 8c to the upper joint. Into plate 10 leg pieces 11b, 11
b This is done by locking the lower end of the tight material fitting groove 8.
The tight members 9, 9 attached to c, 8c are in contact with the base portions 7c, 7c of each draining plate 7, 7,
Prevents rainwater from entering from this area.

In addition, in the event that rainwater enters the interior through the joints between the cover material 8 and the drain plates 7, 7, the presence of the water stop plate 2 and the water guide plates 3, 3 prevents the rainwater from entering between the walls. The water is discharged to the outside through drain ports 6, 6 at the ends of the water guide plates 3, 3.

As described above, in the present invention, the upper and lower joint plates connected by a tension spring sandwich and hold the draining plate attached to the top surface of the wall in a superposed state. Installation is easy, and the cover material attached to the upper joint plate can easily and reliably close the gap between the walls.

In addition, the upper joint plate to which the cover material is attached is in a state of overlap with each draining plate, so that the rising part of each draining plate and the upper joint plate can be prevented from shifting in the direction of expansion between the walls. It is possible to track the distance between the legs of the wall, and conversely, it is possible to track the distance between the upright part of each drain plate and the intervening tension spring for the displacement in the direction of contraction between the walls. It is becoming.

Furthermore, vertical displacement between walls can be accommodated by extension of the tension spring, and when expansion and contraction between walls and vertical displacement combine, the tension spring itself Following is possible through free elastic deformation.

As described above, the device of the present invention has a large deformation absorption ability, so it can accurately follow complex deformations of buildings caused by expansion and contraction of building walls, seismic vibrations, uneven settlement, etc. This provides the effect of reliably closing the space between both walls.
