Description

[Detailed Description of the Invention] The present invention relates to a joint material device with earthquake resistance.
In general, joint materials prevent the occurrence of cracks in the concrete walls of buildings, prevent the growth of cracks, and prevent the intrusion of rainwater, etc., but they also prevent damage to the building when earthquakes or other vibrations act on the building. It is preferable to have the function of preventing this.

The present invention provides a device suitable for this purpose.
A longitudinal synthetic resin substrate 4 having groove-shaped recesses 3 facing the inside and outside of the wall 2 of the building 1, and an engagement device embedded in the wall 2 behind it and engaging with the wall. A pair of synthetic resin joint materials 8 are provided, each comprising a leg piece 7 having a leg piece 5 and a leg piece 7 spaced apart from each other by a distance of 6, each joint material 8,
A relatively elastic partition plate 9 made of a foamed synthetic resin plate is provided at each interval 6, 6 between the partitions 8.

The illustrated example shows a case where elongated joint materials 8, 8 are provided facing each other on the inside 2a and outside 2b of the vertical wall 2 of the building 1, and in this case, the recessed portion of the synthetic resin substrate 4 3 is made of hard synthetic resin by immersing it inside, and a soft synthetic resin layer 4a is superimposed on the outside of the substrate 4.

Further, the leg pieces 7 are formed integrally with the base plate 4 on the left and right sides of the recessed part 3 inside the base plate 4, and in the illustrated example, a space 10 is further left on the side of each leg piece 7, and a second leg piece 1
1 was set.

The joint materials 8, 8 are fixed in advance to formworks 12, 12, such as plywood, for constructing the wall portion 2, with synthetic resin nails 13, etc., and the outer surface 9a is formed between the intervals 6, 6 of each joint material 8, 8. After intervening a partition material 9 such as hardened ethylene foam, concrete 14 is poured and hardened, and the formwork 12 is removed and the protruding tips of the nails 13 are cut off to form the wall portion 2. The joint material 8 is attached to the wall portion 2 at its engagement piece 5.
When vibrations such as earthquakes occur, the recessed portion 3 moves inward and outward, and the partition member 9 acts as a cushion and absorbs the vibration energy of the left and right walls 2, 2. Therefore, the walls 2, 2 are less likely to be damaged.

As described above, according to the present invention, the joint materials 8 having the recessed portions 3 and the intervals 6 are provided on the wall 2 so as to face each other, and elastic partition materials 9 are interposed between the intervals 6 of each joint material 8. As a result, it is possible to prevent damage to the wall portion 2 due to vibration without impairing its function as a conventional joint material, and it is particularly advantageous as a joint material for walls with windows or other openings.
