Description

一种胶合板 技术领域
本发明涉及人造板加工领域，具体地说是一种胶合板。
技术背景
现有的胶合板通常由面层、中间层和底层构成，面层和底层由纵向单板构成，中间层由横向单板构成。这种由横向单板作为中间层的胶合板强度低、承重量有限，在实际使用中不断受到拉伸、剪切、压缩力的考验，在长期使用后从面层到中间层到底层单板容易被持续损坏，不能很好满足用户实际使用需求。
发明内容
本发明提供了一种胶合板。
本发明的目的是解决现有由横向单板作为中间层的胶合板强度低、承重量有限，在长期使用后容易被损坏，不能很好满足用户实际使用需求的问题。
本发明解决其技术问题所采用的技术方案是：一种胶合板，所述胶合板包括面层、中间层和底层，所述中间层位于面层和底层之间，所述面层和底层各由至少一层纵向单板构成，所述中间层由至少一层斜向单板构成，所述斜向单板的斜角a范围为0°＜a＜90°。
优选的，所述斜向单板的斜角a为45度。
本发明的有益效果是：本发明所述的胶合板，其中间层采用斜向单板来替代传统的横向单板，采用斜向单板的胶合板相比于采用横向单板的胶合板，其强度可提高20％以上，大大提高了承重限度，长期使用也不易损坏，能够较好地满足用户使用需求。其当斜向单板的斜角a为45度时最优。
附图说明
图1为本发明实施例1胶合板的结构示意图。
图2为斜向单板的结构示意图。
图3为实施例2胶合板的结构示意图。
图4为实施例3胶合板的结构示意图。
具体实施方式
下面结合附图和实施例对本发明进一步说明：
如图1～2所示，提供了本发明胶合板的实施例1，所述胶合板包括面层1、中间层2和底层3，所述中间层2位于面层1和底层3之间，所述面层1和底层3各由至少一层纵向单板构成，所述中间层2由至少一层斜向单板4构成，所述斜向单板4的斜角a范围为0°＜a＜90°。
当所述斜向单板4的斜角a为45度时为最优，胶合板的强度最好。
如图3所示，提供了本发明胶合板的实施例2，所述胶合板包括面层1A、中间层2A和底层3A，所述中间层2A位于面层1A和底层3A之间，所述面层1A由表及里依次由1、2、3层构成，所述1、2、3层均为纵向单板，所述底层3A依次由7、8、9层的构成，所述7、8、9层均为纵向单板，所述中间层2A由4、5、6层构成，所述4、6层为斜向单板，所述5层为齿接板。
传统的这种胶合板从上到下依次由3层纵向单板、1层横向单板、1层齿接板、1层横向单板、3层纵向单板构成。即本实施例2用斜向单板替代了传统胶合板中的横向单板。
如图4所示，提供了本发明胶合板的实施例3，所述胶合板包括面层1B、中间层2B和底层3B，所述中间层2B位于面层1B和底层3B之间，所述面层1B由表及里依次由1、2、3层构成，所述1、2、3层均为纵向单板，所述底层3B依次由19、20、21层构成，所述19、20、21层均为纵向单板，所述中间层2B由4～18层构成，所述第4、6、7、15、16、18层为斜向单板，所述第5、8～14、17层为纵向单板。
传统的这种胶合板，1～3、5、8～14、17、19～21层为纵向单板，第4、6、7、15、16、18层为横向单板。即本实施例3用斜向单板替代了传统胶合板中的横向单板。
本发明所述的胶合板，其中间层采用斜向单板来替代传统的横向单板，采用斜向单板的胶合板相比于采用横向单板的胶合板，其强度可提高20％以上，大大提高了承重限度，长期使用也不易损坏，能够较好地满足用户使用需求。其当斜向单板的斜角a为45度时最优。
