Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial application field) The present invention relates to a floor cushioning unit arranged between a slab and a roll-out floor set that supports the floor of a gymnasium, sports hall, or the like.

(Prior art) For floors of gymnasiums, sports halls, etc., a number of floor cushioning units are arranged on a slab, and a large number of floor cushioning units are used to support rolled floor sets such as joists and Daihiki. It is formed by assembling floor materials such as floor boards on joists.

And the conventional floor cushioning unit is
As disclosed in Japanese Patent Laid-Open Publication No. 2000-242242, an elastic body such as a coil spring is provided between the roll-out floor assembly and the slab.

(Problems to be solved by the invention) Therefore, when the floor surface of a conventional gymnasium or sports hall is shocked by an impact on the floor surface, the impact is buffered by the elastic body, but the floor surface sways and immediately stops. However, there is a problem in that the body, particularly the joint, is burdened, and the joint is damaged, as well as the burrs that are difficult and give discomfort to the person exercising.

The present invention has been devised in view of the above circumstances, and it is an object of the present invention to, when a shock is applied to a floor surface, to cushion the shock, and to make the floor surface stand still quickly. It is possible to provide a floor cushioning unit that can be used, does not cause discomfort to those who exercise, and can prevent damage to joints and the like.

(Means for Solving the Problem) The present invention for achieving the above-mentioned object is for cushioning a floor arranged between a large-drawing steel having a rectangular cross section and a slab for supporting a floor in a gymnasium or a sports hall. An upper mounting member which is a unit and whose upper part is formed in an open shape by the left and right side surfaces and the bottom surface, and the left and right side surfaces and the bottom surface are closely attached to the left and right side surfaces and the bottom surface of the Daihiki steel, respectively, and the upper mounting member. , An upper part that is attached to the slab side and has left and right side surfaces parallel to the left and right side surfaces outside the left and right side surfaces of the upper mounting member and a bottom surface below the bottom surface of the upper mounting member and parallel to the bottom surface is open. Lower mounting member, a coil spring provided on the bottom surface of the upper mounting member and the bottom surface of the lower mounting member and receiving a load on the side of the upper mounting member, the left and right side surfaces of the upper mounting member, and the left and right sides of the lower mounting member. Installed on the side and each side A rubber elastic body connecting the member and the lower mounting member, and lead provided inside each of the rubber elastic bodies and extending between the left and right side surfaces of the upper mounting member and the left and right side surfaces of the lower mounting member. It is characterized by consisting of a plug.

(Operation) According to the present invention as described above, the vertical impact force applied to the haiki steel is effectively buffered by the elastic force and the damping force.

The elastic force is mainly the compressive elastic force of the coil spring, and the elastic force associated with the shear deformation of the rubber elastic body also acts as an auxiliary force.

The damping force is mainly a damping force associated with the shear deformation of the lead plug, and the damping force associated with the shear deformation of the rubber elastic body also acts as an auxiliary.

To effectively absorb the impact force applied to Daihiki steel, 1.
Ensure sufficient displacement (stroke) of the upper mounting member with respect to the lower mounting member, and 2. Dampen the relative vibration of the upper mounting member with respect to the lower mounting member (and hence the vibration of Daihiki steel). It is necessary to generate the strong damping force for both of them, but according to the above configuration, the necessary stroke and damping force can be easily secured.

(Embodiment) A preferred embodiment of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 shows a sectional side view of the first embodiment.

1 is a floor material of a gymnasium, 3 is a slab, 5 is a unit for cushioning a floor, 7 is a rolling floor set, and the rolling floor set 7 is Daihiki steel 9
And a joist steel 11 which is provided on the Daihiki steel 9 and supports the floor material 1.

A large number of floor cushioning units 5 are arranged on the slab 3, and in the embodiment, Daihiki steel 9 is supported by the floor cushioning unit 5.

The floor cushioning unit 5 is composed of a lower mounting member 13 mounted on the slab 3, an upper mounting member 15 mounted on the Daihiki steel 9, an elastic body 19 having a damping means 17, and the like.

The lower mounting member 13 includes a base 21 and a screw member 23 provided upright on the base 21, and the screw member 23 is mounted on the base 21 via a nut 25.
The height of the base 21 is fixed to the screw hole 21E of the base 21 and the flange 21A of the base 21 is fixed to the slab 3 with a screw 27 for concrete.

On the upper end of the screw member 23, a U-shaped bent piece 31 made of sheet metal is provided.

The bent piece 31 includes left and right side surface portions 31A parallel to both side surfaces of the Daihiki steel 9 and a bottom surface portion 31B parallel to the bottom surface of the Daihiki steel 9.

The upper mounting member 15 is made of sheet metal and is composed of a substantially U-shaped bent piece 16. The bent piece 16 sandwiches the Daihiki steel 9 between its left and right side surfaces 16A, and the upper ends of the left and right side surfaces 16A are bolts 33 and nuts 35. Tighten with and attach to Daihiki steel 9.

In the embodiment, the elastic body 19 is composed of a rubber elastic body 37 and a coil spring 39, and the rubber elastic body 37 has the side surface portions 16
The coil spring 39 is vulcanized and joined between A and 31A, and the coil spring 39 is a bent piece.
A rubber elastic body 37 is interposed between the bottom surface portion 16B of the bottom portion 16B of the bending piece 16 and the bottom surface portion 31B of the bending piece 31, and the upper and lower mounting members 13 and 15 are connected to form a unit.

In this embodiment, a lead plug having a circular cross section is used as the damping means 17.
It extends between 16A and 31A.

In the above structure, the floor material 1 is elastically supported by the shearing force of the rubber elastic body 37 of the floor cushioning unit 5 and the elastic force of the coil spring 39 via the hauling steel 9 and the joist steel 11.

When the floor material 1 is impacted, the impact is rubber elastic body.
It is buffered by 37 and the coil spring 39.

When the impact is applied, the impact is damped by the plastic deformation resistance of the lead plug. Therefore, when a shock is applied to the floor surface, the floor surface can be quickly stopped.

(Effects of the Invention) As is apparent from the above description, according to the floor cushioning unit of the present invention, when a shock is applied to the floor surface, it is of course necessary to buffer the shock, and It can be made stationary, does not give an uncomfortable feeling to a person exercising, and softens the impact applied to the body, especially the joints, and prevents damages to the joints and the like.
