Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to roof structures for gymnasiums, auditoriums, etc.

(Prior Art) Ball games such as volleyball, basketball, and handball are played indoors such as gymnasiums and auditoriums.

In such ball games, the ball is sometimes raised too high, and if the ball is raised too high, it may come into contact with or collide with the field board.

However, conventionally, no means has been adopted to prevent the ball from contacting or colliding with the field board.

[Problem that the invention seeks to solve]

The roof board is made of wood wool cement board, wood wool magnesium board, grouse wall, etc., and usually the roof board forms the ceiling surface. If the ball comes into contact with or collides with such a field board, it may damage the field board, and it may also cause damage to the underside of the field board such as wood wool, cement powder, glass fiber pieces, wood fiber pieces, and other components of the field board. The adhering dust and the like may fall, which impedes the progress of the competition, and furthermore, there is a risk that the health of the athletes will be adversely affected by the inhalation of the fallen pieces.

[Means for solving problems]

In view of the various problems that occur during games due to the balls contacting or colliding with the field boards in the conventional roof structure described above, the present invention aims to prevent the ball raised high from directly contacting or colliding with the field boards. The purpose is to provide roof structures.

In order to achieve this object, the present invention is characterized in that a space below the shedding board is formed and an impact prevention board is provided therein.

〔Example〕

Embodiments of the present invention will be described in detail below with reference to the drawings.

"First Example" FIGS. 1 and 2 show an embodiment of the roof structure of the present invention.

In the figure, reference numeral 1 indicates a roof board, and 2 indicates a roof board, which are conventionally known. This embodiment is characterized in that a space is formed below the sheathing board 1 and an impact prevention board 3 is stretched therein. This impact prevention plate 3 is made of gold rim.
Other materials such as high mesh, expanded metal, and punched metal can be used, but the material and structure are not critical as long as they can prevent the ball from contacting and colliding with the field board 1.

The impact prevention board 3 forms an appropriate space below the roof board l and is stretched so as to cover the entire surface.

The tensioning state may be such that a flat impact prevention plate 3 is fixed between the upper surfaces of the roof support girders (purlins) 4, as shown by chain lines in FIG. The locking pieces 5 bent upward into an L-shape may be continuously provided at both end portions facing the upper side, and the locking pieces 5 may be placed and fixed on the supporting girders 4 on both sides. After all, as long as the entire lower part of the field board 1 can be covered and the ball can be prevented from contacting and colliding with the field board 1, it does not matter how it is stretched.

By constructing and fixing the impact prevention plate 3 between the support girder members 4 as described above, two spaces are formed between the impact prevention plate 3 and the roofing board 1.

The material of the roof board is not limited to asbestos slate, metal, tiles, etc., and any conventional roofing structure can be used.

"Second Embodiment" FIG. 3 shows another embodiment of the present invention, in which the same parts as described above are denoted by the same reference numerals.

This embodiment is characterized in that an uneven surface 6 is formed on the impact prevention plate 3 between the support beam members 4, and the other structure is the same as that of the previous embodiment.

The uneven surface 6 may have a rectangular shape as shown in the figure, or may have a circular depression or other shape.

〔Effect of the invention〕

As described above, by installing the impact prevention plate 4 below the field board 1 to form an appropriate space, even if the ball in an indoor ball game is raised high, the prevention plate 4 will block the ball. This will prevent it from coming into contact with or colliding with the roof board.

Therefore, the roofing boards will not be damaged and powder particles, dust, etc. will not fall onto the stadium.

In addition, since impact prevention plates are installed prior to roof construction, they can prevent workers from falling and also prevent construction equipment and materials from falling, ensuring the safety of workers on the floor. It is something.

In particular, by forming various uneven surfaces 6 on the impact prevention plate 3, the flat surface can be reinforced, and the plate will not bend and exhibits robustness even when hit hard by a ball. Furthermore, by forming the uneven surface 6 into various shapes, it is possible to achieve a decorative effect.

[Brief explanation of drawings]

Fig. 1 is a sectional view showing one embodiment of the roof structure of the present invention;
The figure is a front view showing another embodiment of the impact prevention plate. 1 is a roof board, 2 is a roof board, 3 is an impact prevention board, 4 is a support beam material, and 6 is an uneven surface.

Claims (3)

[Claims] (1) A roof structure for a gymnasium, auditorium, etc., characterized in that a space is formed below a field board 1 and a shock prevention board 3 is stretched over the entire surface. (2) A roof structure for the roof of a gymnasium, auditorium, etc., characterized by forming an uneven surface 7 on an impact prevention plate 3 stretched over the entire surface with a space formed below the field plate 1. (3) A locking piece 5 is provided on both sides of the impact prevention plate 3, and the locking piece 5 is fixed to the roof support girder 4, as claimed in claim 1. and the roof structure described in Section 2.
