具体实施方式detailed description
以下结合附图对本实用新型的实施例作详细描述。Embodiments of the utility model are described in detail below in conjunction with the accompanying drawings.
如图1和2所示，一种三层实木复合地板，包括从上至下依次设置的面板1、芯板2和底板3，所述芯板2由一整块木板构成，且芯板2的上下两面均开设有若干个应力释放槽4，芯板2上表面开设的应力释放槽4与下表面开设的应力释放槽4交错设置；所述应力释放槽4的长度方向与芯板2纹理方向平行；所述面板1与底板3的纹理方向均与芯板纹理方向垂直。所述面板1、芯板2和底板3是采用旋切的加工方式得到的。当然，面板1、芯板2和底板3的纹理方向是与水平方向平行的。As shown in Figures 1 and 2, a three-layer solid wood composite floor includes a panel 1, a core board 2 and a bottom board 3 arranged in sequence from top to bottom, the core board 2 is composed of a whole piece of wood, and the core board 2 There are several stress relief grooves 4 on the upper and lower sides of the core board 2, and the stress relief grooves 4 on the upper surface of the core board 2 are arranged alternately with the stress relief grooves 4 on the lower surface; The directions are parallel; the grain directions of the panel 1 and the bottom plate 3 are both perpendicular to the grain direction of the core board. The panel 1, the core board 2 and the bottom board 3 are obtained by rotary cutting. Of course, the grain direction of the face plate 1, the core plate 2 and the bottom plate 3 is parallel to the horizontal direction.
本实用新型，由于芯板2由一整块木板构成，故其在材质、密度等方面的差异小，进而提高了地板整体的稳定性，减少了“波浪纹”出现的概率。在芯板2为一整块木板的基础上，在芯板2的上下两面均开设有应力释放槽4，使得芯板2上下两面的应力都得到了均匀地释放，降低了芯板2的翘曲变形量，进而提高了地板整体的稳定性，减少了“波浪纹”出现的概率，延长了地板的使用寿命。In the utility model, since the core board 2 is composed of a whole piece of wood, the difference in material, density, etc. is small, thereby improving the overall stability of the floor and reducing the probability of "wave patterns". On the basis that the core board 2 is a whole piece of wood, stress relief grooves 4 are provided on the upper and lower sides of the core board 2, so that the stress on the upper and lower sides of the core board 2 is evenly released, reducing the warping of the core board 2 The amount of warpage is reduced, thereby improving the overall stability of the floor, reducing the probability of "wavy patterns" and prolonging the service life of the floor.
面板1与底板3的纹理方向均与芯板2纹理方向垂直，使得横纹和顺纹之间相互交错，起到相互拉扯的作用，从而减少了地板在水平方向的变形。The grain directions of the panel 1 and the bottom plate 3 are both perpendicular to the grain direction of the core plate 2, so that the horizontal grain and the parallel grain are interlaced and pull each other, thereby reducing the deformation of the floor in the horizontal direction.
由于芯板2上表面开设的应力释放槽4与下表面开设的应力释放槽4交错设置，这样，相互配合，使得芯板2上的应力得以更充分的释放。Since the stress relief grooves 4 on the upper surface of the core board 2 and the stress relief grooves 4 on the lower surface are arranged alternately, the stress on the core board 2 can be released more fully by cooperating with each other.
优选地，所述应力释放槽4为“一”字形且横穿芯板2。即当芯板为长方体时，应力释放槽4的长度与芯板2的宽度大小一致，具体如图1所示。应力释放槽4的长度方向与芯板2纹理方向平行，这样可以更好释放应力。当“一”字形应力释放槽4横穿过芯板2时，可以更均匀的释放应力。Preferably, the stress relief groove 4 is in the shape of a "one" and crosses the core board 2 . That is, when the core plate is a cuboid, the length of the stress relief groove 4 is consistent with the width of the core plate 2 , as shown in FIG. 1 . The length direction of the stress relief groove 4 is parallel to the grain direction of the core plate 2, so that the stress can be better released. When the "one"-shaped stress relief groove 4 crosses the core plate 2, the stress can be released more uniformly.
当面板1、芯板2和底板3为长方体形或者地板为长方体形时，可以设置面板1和底板3为顺纹，芯板2为横纹。由于木材吸湿膨胀后，主要是横纹方向的变化，当面板1和底板3为顺纹，芯板2为横纹时，使得横纹和顺纹之间相互交错，起到相互拉扯的作用，从而减少了地板在水平方向的变形。另外，面板1和底板3采用顺纹实木板，即面板1和底板3的纹理方向与地板的长度(面板1和底板3长度)方向一致，增加了力学强度，使得面板1和底板3更加不容易撕裂。When the face plate 1, the core plate 2 and the bottom plate 3 are in the shape of a cuboid or the floor is in the shape of a cuboid, the face plate 1 and the bottom plate 3 can be arranged to be along the grain, and the core plate 2 can be set to be the transverse grain. After the wood absorbs moisture and expands, it is mainly the change of the direction of the transverse grain. When the panel 1 and the bottom plate 3 are along the grain, and the core plate 2 is the transverse grain, the transverse grain and the parallel grain are interlaced to play a role of pulling each other, thus Reduced deformation of the floor in the horizontal direction. In addition, the panel 1 and the bottom panel 3 are made of solid wood boards along the grain, that is, the direction of the grain of the panel 1 and the bottom panel 3 is consistent with the length of the floor (the length of the panel 1 and the bottom panel 3), which increases the mechanical strength and makes the panel 1 and the bottom panel 3 more stable. Easy to tear.
芯板2上表面开设的应力释放槽4与下表面开设的应力释放槽4交错设置，这样，相互配合，使得芯板上的应力得以更充分的释放。The stress relief grooves 4 on the upper surface of the core board 2 and the stress relief grooves 4 on the lower surface are arranged alternately, so that the stress on the core board can be more fully released by cooperating with each other.
优选地，所述面板1的厚度：芯板2的厚度：底板3的厚度为4:7:4或3:9:3。由于面板1和底板3相对于芯板2是对称结构，故地板使用起来更加稳定，另外，芯板2的比例稍大，可以保证整个地板的强度。当然，采用4:7:4或3:9:3可以让整个地板更加结实耐用,特别是4:7:4最耐用。Preferably, the thickness of the panel 1 : the thickness of the core plate 2 : the thickness of the bottom plate 3 is 4:7:4 or 3:9:3. Since the panel 1 and the bottom plate 3 are symmetrical structures with respect to the core plate 2, the floor is more stable to use. In addition, the proportion of the core plate 2 is slightly larger, which can ensure the strength of the entire floor. Of course, using 4:7:4 or 3:9:3 can make the whole floor more durable, especially 4:7:4 is the most durable.
优选地，所述应力释放槽4的深度为芯板厚度的50％-70％，宽度为2～3mm，设置于芯板2一个面上相邻应力槽之间的间距为40mm～100mm，具体标注见图2。由于应力释放槽4太大会影响芯板的力学强度，太小又起不到释放应力的作用，这样选择，芯板2的力学强度和释放应力的能力达到最好。为了制造容易和更好的释放应力，可以选择设置于芯板2一个面的相邻应力释放槽4之间的间距相等，且开设于芯板上表面的相邻应力释放槽之间的间距与开设于芯板下表面的相邻应力释放槽之间的间距相等。当应力释放槽大小尺寸相同时，上表面的某一个应力释放槽的中心至设置于下表面的离该应力释放槽最近的两个应力释放槽的中心在水平方向上的距离相等，且该距离是上表面任意两个应力释放槽中心之间在水平方向上的距离的一半时，应力得以最均匀充分的释放。Preferably, the depth of the stress relief groove 4 is 50%-70% of the thickness of the core plate, the width is 2-3mm, and the distance between adjacent stress grooves arranged on one surface of the core plate 2 is 40mm-100mm, specifically See Figure 2 for labels. Since the stress relief groove 4 is too large, it will affect the mechanical strength of the core plate, and if it is too small, it will not be able to release the stress. If this is selected, the mechanical strength of the core plate 2 and the ability to release stress will be the best. For ease of manufacture and better stress relief, the spacing between adjacent stress relief grooves 4 on one side of the core plate 2 can be selected to be equal, and the distance between adjacent stress relief grooves on the upper surface of the core plate is the same as The distance between adjacent stress relief grooves opened on the lower surface of the core plate is equal. When the size of the stress relief grooves is the same, the distance from the center of a certain stress relief groove on the upper surface to the centers of the two stress relief grooves closest to the stress relief groove on the lower surface in the horizontal direction is equal, and the distance When it is half of the distance in the horizontal direction between the centers of any two stress relief grooves on the upper surface, the stress can be released most evenly and fully.
优选地，所述面板、芯板、底板的含水率均控制在10％以下，低含水率设置是防止地板失水导致的弯曲变形。可以选择面板的含水率为8％～9％；芯板的含水率为6％～8％；底板的含水率为4％～6％。由于一般面板1、芯板2和底板3的材种不一样，故其物理力学性能差异也较大，面板1、芯板2和底板3的含水率这样设置是为了减少养生过程中因应力释放而导致的板子弯曲变形。Preferably, the moisture content of the panel, core board, and bottom board is all controlled below 10%, and the low moisture content setting is to prevent the floor from bending deformation caused by water loss. It can be selected that the moisture content of the panel is 8% to 9%, the moisture content of the core board is 6% to 8%, and the moisture content of the bottom plate is 4% to 6%. Because the materials of the panel 1, core panel 2 and bottom panel 3 are generally different, their physical and mechanical properties are also quite different. The moisture content of the panel 1, core panel 2 and bottom panel 3 is set in this way to reduce stress release during the curing process resulting in bending of the board.
当然，地板四周可以开设榫槽，且底板3的下表面滚涂防水漆，地板的侧面封蜡，面板1的上表面涂布除醛油漆。进而可以很好的防潮。Of course, tenons and grooves can be provided around the floor, and the lower surface of the bottom plate 3 is coated with waterproof paint, the side of the floor is sealed with wax, and the upper surface of the panel 1 is coated with aldehyde-removing paint. And then can be very good moisture-proof.
优选地，所述底板3为松木或杨木单板。Preferably, the bottom board 3 is pine or poplar veneer.
优选地，所述面板1为实木单板，包括整板和拼板两种。面板可以采用橡木单板。Preferably, the panel 1 is a solid wood veneer, including two types of whole board and panel. The panel can be made of oak veneer.
优选地，所述面板1与芯板2、芯板2与底板3之间均通过无醛胶粘合。进而更加环保。Preferably, the panel 1 and the core board 2, and the core board 2 and the bottom board 3 are bonded by formaldehyde-free glue. And thus more environmentally friendly.
可以选择面板和芯板所用木材材质不同，面板1所用的材料质量比较好，价格较贵，密度较大，芯板2所用的材料质量较差，价格较便宜，密度较小，例如面板1所用木材为橡木；所述芯板2所用木材为松木。You can choose different wood materials for the panel and the core board. The material used for panel 1 is of better quality, more expensive, and denser. The material used for core board 2 is of poorer quality, cheaper, and less dense. For example, the material used for panel 1 The wood is oak; the wood used for the core board 2 is pine.
需要说明的是，当面板1、芯板2和底板3是长方体形或者地板为长方体形，地板水平放置即地板的底板在下，面板在上，水平放置于地面上的情况下：本实用新型顺纹指的是地板长度方向与木材的纹理方向一致，例如：可以是面板1或者底板2的长度方向与木材的纹理方向一致；横纹指的是地板的宽度方向与木材的纹理方向一致，例如可以是芯板2的宽度方向与木材的纹理方向一致(具体可见图1)，厚度指的是竖直方向的厚度，应力释放槽的深度指的的竖直方向的深度，应力释放槽的宽度指的是地板长度方向的宽度。例如图1或者图2中，左右方向是地板的长度方向，垂直于阅读面的方向是地板的宽度方向。图2中板厚指的是芯板的厚度。It should be noted that when the panel 1, the core plate 2 and the bottom plate 3 are in the shape of a cuboid or the floor is in the shape of a cuboid, and the floor is placed horizontally, that is, the bottom plate of the floor is at the bottom, the panel is at the top, and the floor is placed horizontally on the ground: Pattern means that the length direction of the floor is consistent with the grain direction of the wood, for example: the length direction of the panel 1 or bottom plate 2 is consistent with the grain direction of the wood; horizontal grain means that the width direction of the floor is consistent with the grain direction of the wood, for example It can be that the width direction of the core board 2 is consistent with the grain direction of the wood (see Figure 1 for details), the thickness refers to the thickness in the vertical direction, the depth of the stress relief groove refers to the depth in the vertical direction, and the width of the stress relief groove Refers to the width of the floor lengthwise. For example, in FIG. 1 or FIG. 2 , the left-right direction is the length direction of the floor, and the direction perpendicular to the reading surface is the width direction of the floor. The plate thickness in Figure 2 refers to the thickness of the core plate.
惟以上所述者，仅为本实用新型之较佳实施例而已，当不能以此限定本实用新型实施之范围，即大凡依本实用新型权利要求及实用新型说明书所记载的内容所作出简单的等效变化与修饰，皆仍属本实用新型权利要求所涵盖范围之内。此外，摘要部分和标题仅是用来辅助专利文件搜寻之用，并非用来限制本实用新型之权利范围。But what is described above is only a preferred embodiment of the utility model, and should not limit the scope of the utility model implementation with this, that is, all the simple things made according to the claims of the utility model and the contents recorded in the specification of the utility model Equivalent changes and modifications all still fall within the scope covered by the claims of the present invention.
