7、籃板支架要作如下包扎:
(1)在籃板背后,高度低于2.75米的任何籃板支架,要在其下表面包扎,直到距籃板正面1.20米處。
包扎物的最小厚度為0.05米(5厘米),并且其密度與籃板包扎物的密度相同;
(2)所有可移動的籃板,在面向籃球場的基座表面必須要全面地釓扎,包扎的最低高度為2.15米。
包扎物的最小厚度為0.15米(15厘米)
球籃 球籃包括籃圈和籃網。
1、籃圈要按如下要求制作:
(1)實心鐵條,內徑為0.45米(45厘米),漆成橙色;
(2)圈條的直徑最小為0.017米(17毫米),最大為0.020米(2 0毫米),圈的下沿設有小環或類似的東西,以便懸掛籃網;
(3)它們要牢固地安裝在籃板上(見下面注),籃圈頂面要成水平,離地板3.05米,與籃板兩垂直邊的距離相等;
注:我們建議:最好把籃圈安裝在籃板的結構架上,這樣,籃圈上所受的力就不會直接作用到籃板上。
(4)籃板面距籃圈內沿的最近點是0.15米(15厘米);
(5)可以使用抗壓籃圈。它們要符合下列技術條件:
a、它們要具有與那些不可活動的籃圈完全相同的反彈特性。定壓裝置要保證這些特性,并保護籃圈和籃板。籃圈的設計及制造可保證隊員的安全;
b、具有定力鎖定器的那些籃圈,在離籃圈最遠點圈頂上施加靜荷載未到105千克時,定壓裝置絕不能松動;
c、當定壓裝置打開時,籃圈向下轉動,與原來水平位置的夾角不得超過30度;
d、當定壓裝置打開并不再施載后,籃圈要自運返回到原來位置。
2、籃(lan)(lan)網用白(bai)色的細繩結(jie)成,懸(xuan)掛在籃(lan)(lan)圈上;它的結(jie)構要(yao)能夠使球(qiu)穿過球(qiu)籃(lan)(lan)時(shi)有暫時(shi)的停(ting)頓。網長不短(duan)于0.40米(mi)(40厘米(mi)),不長于0.45米(mi)(45厘米(mi))
籃球場地規格,籃球場木地板
籃球場地的規格是根據籃球比賽規則規定的。標準籃球場地為一塊長28米,寬15米的長方形平地。球場必須有明顯的界線。界線外至少2米以內沒有任何障礙物,界線與觀眾之間也至少應有2米的距離。
球(qiu)場長(chang)邊(bian)的(de)(de)(de)界線(xian)(xian)(xian)(xian)(xian)叫(jiao)(jiao)邊(bian)線(xian)(xian)(xian)(xian)(xian),短邊(bian)的(de)(de)(de)界線(xian)(xian)(xian)(xian)(xian)叫(jiao)(jiao)端(duan)線(xian)(xian)(xian)(xian)(xian)。連接(jie)兩條(tiao)邊(bian)線(xian)(xian)(xian)(xian)(xian)中(zhong)(zhong)(zhong)點(dian)(dian)的(de)(de)(de)平行(xing)于端(duan)線(xian)(xian)(xian)(xian)(xian)的(de)(de)(de)橫線(xian)(xian)(xian)(xian)(xian)叫(jiao)(jiao)中(zhong)(zhong)(zhong)線(xian)(xian)(xian)(xian)(xian),中(zhong)(zhong)(zhong)線(xian)(xian)(xian)(xian)(xian)應向兩側邊(bian)線(xian)(xian)(xian)(xian)(xian)外各(ge)延長(chang)15厘米。以(yi)中(zhong)(zhong)(zhong)線(xian)(xian)(xian)(xian)(xian)的(de)(de)(de)中(zhong)(zhong)(zhong)點(dian)(dian)為圓心,以(yi)1.8米為半徑所(suo)畫成(cheng)的(de)(de)(de)圓叫(jiao)(jiao)中(zhong)(zhong)(zhong)圈。罰(fa)球(qiu)線(xian)(xian)(xian)(xian)(xian)是一(yi)條(tiao)與端(duan)線(xian)(xian)(xian)(xian)(xian)平行(xing)的(de)(de)(de)直(zhi)線(xian)(xian)(xian)(xian)(xian),其中(zhong)(zhong)(zhong)點(dian)(dian)必須與端(duan)線(xian)(xian)(xian)(xian)(xian)與中(zhong)(zhong)(zhong)線(xian)(xian)(xian)(xian)(xian)的(de)(de)(de)中(zhong)(zhong)(zhong)點(dian)(dian)在(zai)一(yi)條(tiao)直(zhi)線(xian)(xian)(xian)(xian)(xian)上。罰(fa)球(qiu)線(xian)(xian)(xian)(xian)(xian)以(yi)及(ji)罰(fa)球(qiu)線(xian)(xian)(xian)(xian)(xian)兩端(duan)連接(jie)端(duan)線(xian)(xian)(xian)(xian)(xian)的(de)(de)(de)兩條(tiao)斜線(xian)(xian)(xian)(xian)(xian)所(suo)構成(cheng)的(de)(de)(de)區域叫(jiao)(jiao)限制區(三秒區)。
