Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to improvement of an inner wall structure of an indoor stadium or the like.

[Conventional technology]

Generally, in indoor stadiums such as gymnasiums, an elastic function is added to the floorboard, so that it is structured to absorb the impact received from the floor during the competition, but the inner wall structure that constitutes the inner peripheral surface of the stadium is The reality is that no such consideration is given.

However, recently, attention has been focused on the safety in the case of collision with the inner wall of the indoor stadium during the competition, and by giving an elastic function to the inner wall as well, the impact on the body at the time of collision can be prevented. There is a request to soften as much as possible.

Under the above-mentioned demand, the applicant of the present application has previously proposed, as an inner wall structure having an elastic function, Japanese Utility Model Laid-Open No. 2-72708. As shown in FIG. 1, a support stand 2 having an elastic function is erected on a concrete foundation wall 1 as an inner wall at predetermined intervals, and a furring strip 3 having a substantially hat-shaped cross section is fixed to the support stand 2. At the same time, the interior wall material 5 that forms the surface of the inner wall is attached through the fixing metal fittings 4 attached to the furring strip material 3, and when the athlete collides with the surface of the interior wall material 5, the impact force Is absorbed by the elastic action of the elastic material provided on the support stand 2 to soften the impact on the body and prevent injury.

[Problems to be solved by the device]

However, in the above-described inner wall structure, as shown in FIG. 2, the interior wall material 5 is formed in a horizontally long shape, and the groove portions 6a and 6b are formed in the upper and lower ends thereof, respectively. Is crossed over a plurality of furring strips 3 in the left-right direction, and the fixing metal fittings 4 fixed to the furring strips 3 are fitted and locked in the grooves 6a and 6b to successively join the interior wall materials 5. Therefore, for example, if there is unevenness 1 on the concrete foundation wall 1, the height dimension between the surface of the foundation wall and each fixing bracket 4
Since h ₁ , h ₂ and h ₃ cannot be kept constant, the interior wall material 5 cannot be easily attached, or the metal fittings 4 are fixed in the grooves 6a and 6b.
However, there is a problem in that the interior wall material 5 is mounted in a warped state and the flatness cannot be obtained if it is forcibly fitted.

Therefore, the technical problem of the present invention is to improve the workability when mounting the interior wall material and to obtain the flatness of the interior wall material.

[Means for Solving the Problems]

In order to solve the above-mentioned technical problems, the present invention is provided with a furring strip 3 on a height-adjustable support stand 2 which is erected on a foundation wall 1, and a furring bracket 4 is interposed on the furring strip 3. In an inner wall structure such as an indoor stadium in which a rectangular interior wall material 8 is attached, the fixing bracket 4 is formed so as to project outward from the base 19 attached to the furring strip 3 and both sides of the base 19. While having a pair of locking pieces 21a, 21b formed, the interior wall material 8 has an elastic member 13 covering the entire back surface and groove portions 15a, 15b provided on both long side edges, respectively. The groove width of the groove portions 15a, 15b is formed to be larger than the plate thickness of the locking pieces 21a, 21b inserted into the groove portions 15a, 15b.

[Action]

According to the above-mentioned means, the interior wall material 8 is successively spliced while inserting the groove portions 15a, 15b of the interior wall material 8 into the locking pieces 21a, 21b of the fixing fitting 4 attached to the furring strip material 3 and the interior wall material. To form. In this case, there is some unevenness in the foundation wall 1 and the furring material 3
Even if the heights of the fixing metal fittings 4 fixed to the above are not uniform, the height error is absorbed by the property of the elastic member 13 and the groove width of the groove portions 15a and 15b is set to the locking piece 2.
Since it is formed to be thicker than the plate thickness of 1a, 21b, the locking pieces 21a, 21b of the fixing metal fitting 4 can be easily and easily inserted therein. As a result, unlike the conventional case, the fixture 4 is not forcibly fitted into the groove and the interior wall member 8 is not attached in a warped state, and the flatness of the interior wall surface can be maintained.
