Description

[Detailed explanation of the invention] [Industrial field of application] It is designed to absorb the impact received on the floor on the spot, prevent it from spreading to other areas, and shorten the vibration damping time of the floor. This is an idea for a floor structure that can be used in various structures.

[Conventional technology]

The flooring material (buffering material) for gymnasiums was finally established in JIS in 1985, and its performance has been improved to a considerable level and it has become commonplace. Despite the fact that the functions provided are quite different from those for gymnasiums, the basic concept behind the flooring materials manufactured by current manufacturers is exactly the same as that for gymnasiums.

[Problem that the invention attempts to solve]

This design attempts to solve the problem of having to absorb the large impact of a throw and also minimize the range in which that impact spreads.

[Means for solving problems]

Separate the joists and large pulls for each span to create a pin structure, and install a cushioning material at the bottom of the pin structure of the large pull to absorb the impact on the spot, bring out the effect of the cushioning material to a greater extent, and reduce floor vibration. This idea solves the problem by shortening the decay time and reducing vibration noise.

[Effect]

A predetermined number of cylindrical bundles (tsuka) with rubber or springs inserted inside them are arranged and fixed at predetermined locations on the floor of the building, and a square U-shaped cross section (
Place and fix the shaped steel of the shape), insert the ends of the two large tensioners into the shaped steel slightly apart, and insert them almost to the center, pivot them to the shaped steel with pins, and place the joists on the large tensioning against the large tension. Conventionally, the joints were separated by cutting them at right angles and large pitches and securing them with nails, placing waste boards on top of the joists, and then laying folds on top of the wood joists, reinforcing the joints firmly and connecting them. By separating the floor joists and large pulls into each span, it is possible to absorb the impact that would have been received by the floor as a whole, and furthermore, it is possible to prevent the impact from spreading to other areas as much as possible. It is possible to shorten the vibration damping time of the floor and to reduce vibration noise.

〔Example〕

A cylindrical bundle (tsuka) 3 with rubber or springs inserted inside is placed on the floor 2 of the structure 1 to sufficiently withstand the number of people and the amount of exercise on the tatami floor, as well as the weight of the tatami, joists, scrap boards, tatami mats, etc. Set the quantity and installation position and fix the arrangement. Approximately 900 in both vertical and horizontal directions
Arrange at mm intervals.

A shaped steel 4 having a U-shaped cross section is placed and fixed on top of the bundle 3. A bolt insertion hole 5 is bored in the shaped steel 4 approximately at the center of the left and right sides.

Furthermore, Ohiki 6 is slightly shorter than the pitch P of each bundle 3.
Prepare the necessary amount of
A hole 7 is drilled at a position that coincides with the hole 5 when inserted close to the center of the hole.

Insert the Ohiki 6 prepared in this way to approximately the center of the shaped steel 4 of the bundle 3 arranged in a line in the vertical or horizontal direction, insert the bolt 8 into the holes 5 and 7, and then tighten the bolt 8.
Tighten and secure with nut 9 from the end. Therefore, since the lengths 6 are slightly shorter than the pitch P of the bundle 3, when the ends of the two lengths 6 are inserted into the steel mold 4, a certain distance is provided between the ends of the lengths 6, and therefore, The large pull 6 is a pin joint for the shaped steel 4.

After that, cut out the joist 10 on the large pull 6 at right angles to the large pull 6 and at the pitch P of the large pull 6, and then cut the joists 11 and nails 12.
A waste board 13 is placed on the joist 10, and a tatami mat 14 is further spread on the waste board 13.

[Effect of idea]

By separating the joists and main pullers into each span and creating a pin structure, the impact that would have been received by the floor as a whole can be absorbed on the spot, making it possible to bring out the effectiveness of the cushioning material even more. . In addition, since the impact is difficult to propagate to other areas, the vibration damping time of the floor can be shortened, and the vibration noise of the floor can be reduced.

Claims (1)

[Scope of utility model registration request] A predetermined number of cylindrical bundles with rubber or springs inserted inside them are placed and fixed at predetermined locations on the floor of the building, a shaped steel with a U-shaped cross section is placed and fixed on top of the bundle, and a large Separate the end of the joist slightly and insert it almost to the center, pivot it to the shape steel with a pin, fix the joist on the joist at right angles to the joist, cut it off at the pitch of the joist, and place it on the joist. The floor structure of a judo hall is made up of a pile of wooden boards placed on top of the wooden table, and then tatami mats laid on top of the wooden pile.
