Description

Technical Field

[0001] The present application relates to the technical field of flooring, and in particular to an assembled flooring. Background Art

[0002] As the market share of composite flooring products in the form of herringbone and herringbone made of multi-layer boards, particle boards or density boards gradually increases, herringbone and herringbone composite solid wood floors made of solid wood boards have emerged on the market. Although the structure of composite solid wood floors and composite composite floors is basically the same, because solid wood materials have obvious anisotropy and relatively large shrinkage and swelling rates, composite solid wood floors will have more serious misalignment problems after being used for a period of time than composite composite floors. Utility Model Content

[0003] After long-term research and practice, the inventor found that the cause of the misaligned joints of composite solid wood floors is that the shrinkage and swelling deformation trend of a single composite block in the width direction is neither perpendicular nor parallel to the joints between adjacent composite blocks. Specifically, taking the herringbone composite solid wood floor as an example, Figure 1 The figure shows a common herringbone composite solid wood floor in the prior art, including a herringbone composite block A and a herringbone composite block B that are mirror images of each other, and the angles between the long side and the short side are 60° and 120°. During the manufacturing process, the long side is made parallel to the axial section of the wood, and the short side is obtained by cutting with the long side as the reference plane. Therefore, the direction l1 of the deformation trend of the herringbone composite block A due to shrinkage and swelling due to moisture is actually perpendicular to the long side, but is neither perpendicular nor parallel to the joint of the herringbone composite block B. The same applies to the direction l2 of the deformation trend of the herringbone composite block B. This situation results in that once the herringbone composite block A and / or the herringbone composite block B undergo dimensional deformation due to shrinkage and swelling, the joint surfaces of the two will no longer be parallel, resulting in the following: Figure 2 The appearance of the triangular seam C shown leads to the problem of misalignment.

[0004] The present application provides a composite floor, which limits the angle between side surfaces so that the deformation trend caused by shrinkage and expansion in the width direction of the composite blocks constituting the composite floor is always perpendicular to the joints, thereby avoiding the problem of misaligned joints.

[0005] Specifically, the present application provides a combined floor, comprising a combined block A and a combined block B that can be spliced, the four side surfaces of the combined block A are all perpendicular to the surface, and the four side surfaces in a clockwise direction are respectively a first long side surface of block A, a first short side surface of block A, a second long side surface of block A, and a second short side surface of block A; the four side surfaces of the combined block B are all perpendicular to the surface, and the four side surfaces in a clockwise direction are respectively a first long side surface of block B, a first short side surface of block B, a second long side surface of block B, and a second short side surface of block B, the second short side surface of block A is of equal width to the second short side surface of block B; an angle of 135° is formed between the first long side surface of block A and the first short side surface of block A, and an angle of 90° is formed between the first long side surface of block A and the first short side surface of block A; an angle of 45° is formed between the first long side surface of block B and the first short side surface of block B, and an angle of 90° is formed between the first long side surface of block B and the first short side surface of block B.

DETAILED DESCRIPTION

[0029] In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of this application.

[0030] Example 1: Reference Figure 3-5 The composite floor shown comprises a composite block A 1 and a composite block B 2 which can be spliced ​​together.

[0031] The four sides of the combined nail block 1 are perpendicular to the surface, and the four sides are respectively the first long side 11 of the nail block, the first short side 12 of the nail block, the second long side 13 of the nail block, and the second short side 14 of the nail block in the clockwise direction. There is an angle of 135° between the first long side 11 of the nail block and the first short side 12 of the nail block, and there is an angle of 90° between the first long side 11 of the nail block and the second short side 14 of the nail block. Correspondingly, there is an angle of 45° between the second long side 13 of the nail block and the first short side 12 of the nail block, and there is an angle of 90° between the second short side 14 of the nail block.

[0032] The four sides of the combined block 2 are perpendicular to the surface, and the four sides are respectively the first long side 21 of the block, the first short side 22 of the block, the second long side 23 of the block, and the second short side 24 of the block in the clockwise direction. Among them, there is an angle of 45° between the first long side 21 of the block and the first short side 22 of the block, and there is an angle of 90° between the first long side 21 of the block and the second short side 24 of the block. Correspondingly, there is an angle of 135° between the second long side 23 of the block and the first short side 22 of the block, and an angle of 90° between the second short side 24 of the block.

[0033] In order to enable the combination A block 1 and the combination B block 2 to be assembled, the second short side surface 14 of the A block and the second short side surface 24 of the B block are of equal width, that is, the widths of the two are equal. The lengths of the two can be equal or unequal. In other words, the first long side surface 11 of the A block and the second long side surface 23 of the B block can be of equal length or unequal length. This embodiment takes the unequal lengths as an example.

[0034] When assembling, the first long side surface 11 of block A is connected with the second short side surface 24 of block B, and the second short side surface 14 of block A is flush with the second long side surface 23 of block B, so as to form a first unit 71. The first short side surface 12 of block A and the first short side surface 22 of block B of two adjacent first units 71 are connected to make them wider. The second long side surface 13 of block A and the first long side surface 11 of block A, and the first long side surface 21 of block B and the second long side surface 23 of block B are connected to make them longer.

[0035] By means of the improvement of the above structure, by limiting the angles between the first long side surface 11 of block A and the first short side surface 12 and the second short side surface 14 of block A, and the angles between the first long side surface 21 of block B and the first short side surface 22 and the second short side surface 24 of block B, it is possible to ensure that the deformation trend l1 of the combined block A 1 after assembly is perpendicular to the joint seam between it and the combined block B 2, and the joint seam of another combined block A 1 spliced ​​therewith. The deformation trend l2 of the combined block B 2 when encountering changes in dryness and humidity is the same as that of the combined block A 1. Therefore, when deformation occurs, multiple combined blocks A 1 and multiple combined blocks B 2 are deformed as a whole, and triangular seams will not be formed due to the size changes of shrinkage and swelling, and the problem of misalignment caused by the triangular seams will not be caused. The deformation trend l1 of the combined block A 1 is also perpendicular to the deformation trend l2 of the combined block B 2. Therefore, at the joint between the first short side 12 of block A and the second short side 22 of block B, the combined block A 1 and the combined block B 2 also deform as a whole, and no triangular seam will be formed due to the size change caused by shrinkage and swelling, nor will the problem of misaligned seams caused by the triangular seam.

[0036] The tongue and groove used to form a fixed connection between the combined block A 1 and the combined block B 2 can be of the prior art, such as a lock structure, a general flat structure, or use an additional connecting fastener. In this embodiment, the lock structure is taken as an example. The lock combination of the combined block A 1 and the combined block B 2 only needs to satisfy the requirement that the two can be assembled and combined. In other words, it only needs to satisfy the following requirements: the first long side surface 11 of block A and the first long side surface 21 of block B both have a female tenon structure or a male tenon structure; the first long side surface 11 of block A and the first short side surface 12 of block A both have a female tenon structure or a male tenon structure; the first long side surface 21 of block B and the second short side surface 24 of block B both have a female tenon structure or a male tenon structure.

[0037] For example, the first long side surface 11 of block A is a female tenon structure (x), the first short side surface 12 of block A is a female tenon structure (x), the second long side surface 13 of block A is a male tenon structure (y), and the second short side surface 14 of block A is a male tenon structure (y); the first long side surface 21 of block B is a female tenon structure (x), the first short side surface 22 of block B is a male tenon structure (y), the second long side surface 23 of block B is a male tenon structure (y), and the second short side surface 24 of block B is a female tenon structure (x).

[0038] In some other embodiments, reference Figure 6 As shown, the second short side surface 14 of block A is connected to the first long side surface 21 of block B, and the first long side surface 11 of block A is flush with the second short side surface 24 of block B to form a second unit 72. The first unit 71 and the second unit 72 are connected by connecting the first short side surface 12 of block A of the first unit 71 with the first short side surface 22 of block B of the second unit 72.

[0039] Example 2: Reference Figure 7 As shown, the combined floor also includes a combined C block 3, which has the same shape as the combined A block 1, but the locking combination method of the combined C block 3 is different from that of the combined A block 1. Specifically, the first long side surface 31 of the C block is a male tenon structure (x), the first short side surface 32 of the C block is a male tenon structure (x), the second long side surface 33 of the C block is a female tenon structure (y), and the second short side surface 34 of the C block is a female tenon structure (y). Therefore, the first short side surface 32 of the C block of the combined C block 3 can be connected with the first short side surface 12 of the A block to be lengthened and combined to form a third unit 73. The third unit 73 can serve as a partition between the two first units 71 and connect the two first units 71 to avoid the accumulation of deformation of multiple columns of the first units 71, thereby more effectively avoiding the occurrence of triangular seams. Similarly, the third unit 73 can also connect the first unit 71 and the second unit 72.

[0040] Or, in some other embodiments, referring to Figure 8As shown, the combined floor also includes a combined T-block 4, which has the same shape as the combined B-block 2, but the locking combination method of the combined T-block 4 is different from that of the combined B-block 2. Specifically, the first long side surface 41 of the T-block is a male tenon structure (x), the first short side surface 42 of the T-block is a female tenon structure (y), the second long side surface 43 of the T-block is a female tenon structure (y), and the second short side surface 44 of the T-block is a male tenon structure (x). Therefore, the first short side surface 42 of the T-block of the combined T-block 4 can be connected with the first short side surface 22 of the B-block to lengthen and combine to form a fourth unit 74. The fourth unit 74 can serve as a partition between the two first units 71 and connect the two first units 71 to avoid the accumulation of deformation of multiple columns of the first units 71, thereby more effectively avoiding the occurrence of triangular seams. Similarly, the fourth unit 74 can also connect the first unit 71 and the second unit 72.

[0041] Example 3: Reference Fig. 9 As shown, the composite floor includes a composite block A 1, a composite block B 2, a composite block C 3, a composite block D 4 and a composite block E 5, and the second long side surface 13 of block A and the second long side surface 33 of block C are staggered and spliced ​​to form a fifth unit 75, the first long side surface 21 of block B and the first long side surface 41 of block D are staggered and spliced ​​to form a sixth unit 76, the end of the fifth unit 75 is spliced ​​with the middle of the sixth unit 76, and the end of the sixth unit 76 is spliced ​​with the middle of the fifth unit 75, thereby forming an installation frame 6, and the composite block E 5 has a shape matching the installation frame 6 and is assembled in the installation frame 6.

[0042] Preferably, in the fifth unit 75, the head of the second long side 13 of block A is aligned with the middle of the second long side 33 of block C; in the sixth unit 76, the head of the first long side 21 of block B is aligned with the middle of the first long side 41 of block D.
