Description

Buffer type composite floor elastic connecting piece and composite floor capable of preventing buckling deformation

Technical Field

The invention relates to a composite floor connecting piece and a composite floor, in particular to a buffer type composite floor elastic connecting piece and a composite floor capable of preventing buckling deformation.

Background

Compared with wood floors, ceramic tile floors and laminate floors, the plastic floors have the advantages of being strong in decoration, convenient to carry and construct, soft, comfortable, wear-resistant, convenient to replace and the like, are widely used as high-end floor decoration materials, gradually replace the wood floors, the ceramic tile floors and laminate floors, become main flow floor decoration materials, and especially in developed areas such as Europe and America, japanese and Korean, the plastic floors are increasingly favored by consumers by virtue of a plurality of advantages. According to different construction forms, the plastic floor is usually manufactured into plastic floor tiles or rolled plastic floors, and the plastic floor tiles are assembled on the ground to form the plastic floor or the rolled plastic floor is directly unfolded and paved on the ground during construction. Plastic floor tiles are more popular in the market because they are lighter and more convenient to handle, construct and replace than roll-up plastic floors.

The plastic floor piece construction on the market often needs to be adhered with the ground with the help of the viscose between the piece and the piece, has increased construction consuming time and cost of labor on the one hand, on the other hand because the viscose often contains the non-environmental protection composition, is unfavorable for the feature of environmental protection of plastic floor, and the viscose easily produces the degumming after ageing for a long time, influences the result of use of plastic floor. In addition, the plastic floor splice block in the single-piece structure form is easy to relatively displace due to the structural factors of the plastic floor splice block, and the plastic floor splice block is easy to deform or warp or arch after long-term expansion and contraction. Therefore, the practical use effect of the plastic floor tile in the form of a single piece structure to be glued by means of glue is not satisfactory.

In order to optimize the use of single-piece construction of plastic floor panels, those skilled in the art, including the applicant, have carried out a great deal of research and improvement, starting from the construction and materials of construction of the plastic floor panels, in an attempt to solve the various drawbacks of single-piece construction of plastic floor panels. For example, those skilled in the art make glue-free plastic floor tiles by providing various structural types of latches on the plastic floor tiles, and using the latches to achieve the splice between the tiles, the glue-free plastic floor tiles provided with the latches can splice the tiles relatively firmly without using glue, but increase the construction difficulty and the manufacturing cost, and at the same time, fail to solve the warpage or camber problem well. For another example, ZL200820117527.2 proposes a thermoplastic elastomer assembled plastic floor, which comprises a substrate and a panel secondarily injection-molded on the surface of the substrate, wherein trapezoidal tenons and mortises are respectively arranged on two corresponding sides of the substrate, and a reticular reinforcing rib is arranged on the back of the substrate. ZL201020259515.0 provides an anti-warp composite floor, and lock catch type joggles are arranged on the periphery of the anti-warp composite floor. Although the spliced floor connected by the lock catch can be tightly connected and locked with adjacent spliced blocks, when the floor is provided with a plurality of edges which are required to be spliced with the adjacent floor, the lock catch joggles at the edges are required to be wedged and fastened at the same time, and the construction is more complicated. In addition, the composite floor spliced by the lock catch type joggle pieces is difficult to disassemble because each edge is locked by the adjacent floor, and the connecting pieces are easy to damage in the disassembling process, so that the spliced floor in the prior art is difficult to replace and maintain. In particular, the fixed locking joggles firmly attach adjacent edges of the floor paint and lack buffer space, and once the volume is expanded and contracted, the composite floor can have deformation problems such as warping, arching, seam pulling and the like.

In order to overcome the problem of difficult installation, the prior art provides a mortarless splice floor. If ZL201220136642.0 provides a novel tenon-free spliced floor, adjacent floors are connected into a whole from the bottom through C-shaped elastic connecting accessories, and only the edges of the floors need to be clamped into the elastic connecting pieces during installation. However, the elastic connecting pieces tighten the edges of the adjacent floor tiles, and when the floor tiles are expanded and contracted, the floor is still easy to warp, arch and other deformation problems occur.

In another example, the floor seam covering assembly provided by ZL2004201030928 is formed by covering the floor seam with an elastic plate-shaped body with a width larger than that of the floor seam, and only enough gaps are reserved between adjacent floors during installation, so that the floor seam covering assembly is embedded into the gaps. The elastic plate-shaped body is provided with a hole-shaped structure, and the plate-shaped body can freely stretch and retract when expanding so as to avoid the deformation of the floor. The structure is simple to install, the floor can be prevented from being damaged in the installation and disassembly processes, and meanwhile, the hole-shaped mechanisms provide a certain buffer space for the adjacent floors. However, in the practical use of the technology, a gap with a fixed size needs to be reserved when a floor is placed, and construction is very difficult. The elastic plate-shaped body is fixed only by the pressure between the elastic plate-shaped body and the released floor, the elastic plate-shaped body has no function of locking the adjacent floor tiles, the elastic plate-shaped body is easy to fall off when the floor tiles shrink, and displacement and sliding between the adjacent floor tiles are easy to occur. The elastic plate body covered on the surface also easily affects the overall appearance of the floor, and if the appearance of the elastic plate body needs to be modified, the application range of the elastic plate body can be reduced, and the production cost can be increased.

Disclosure of Invention

In view of the above, the invention provides a composite floor connecting piece which can effectively eliminate deformation of a composite floor caused by expansion and contraction, can lock adjacent floor blocks and has wide application range.

The aim of the invention is achieved by the following technical scheme: the buffer type composite floor elastic connecting piece comprises a first installation edge and a second installation edge which are arranged side by side, wherein a connecting area for connecting the first installation edge and the second installation edge is arranged between the first installation edge and the second installation edge, and a plurality of first buffer cavities are arranged on the connecting area; and the first installation edge and the second installation edge are respectively provided with an installation assembly for locking the composite floor.

The elastic connecting piece is used for being arranged between two adjacent blocks of the composite floor, and the two adjacent blocks are locked through the installation assembly to prevent sliding and displacement of the blocks. In particular, the invention provides for the connection region, in particular, in which the first buffer cavity can be deformed when subjected to a force in order to change the distance between the first mounting edge and the second mounting edge. For example, when the composite floor board is shrunk, the spacing between the edges of adjacent tiles increases, which pulls the first and second mounting edges, respectively. At this time, the first buffer cavity will be stretched to a certain extent by the pulling of the first installation edge and the second installation edge, so that the connecting piece is prevented from being broken and continuously locked to the splice, and the splice is prevented from loosening, sliding or displacing. For another example, when the composite floor expands, the connectors connected to the edges of the tiles will be compressed by the tiles from both sides, and the volume of the first buffer air is compressed at this time, so as to reduce the distance between the first mounting edge and the second mounting edge, so that the positions of the first mounting edge and the second mounting edge can be kept relatively still with the edges of the tiles all the time, and the tiles are prevented from falling off from the connectors to warp and arch. Particularly, because the distance between the first installation edge and the second installation edge is variable, the width of the connecting piece can be increased by applying larger external force to the splice or the connecting piece, so that the single splice can be conveniently detached and installed, the construction difficulty of laying and maintaining the composite floor is reduced, the damage of the connecting piece can be effectively avoided, and the service life of the composite floor is prolonged. The design of hiding at the bottom of the splice is also beneficial to maintaining the overall appearance of the composite floor, so that the connecting piece has wider application range. In the invention, the connecting piece can be made of materials with strong elastic deformation performance, such as metal, rubber, plastic and the like.

Further, the first buffer cavities are arranged in a single row or a plurality of rows.

When the width of the connecting area is larger, the first buffer cavities arranged in a single row are difficult to meet the expansion and contraction requirements of the buffer splice blocks, and the buffer splice blocks are easy to damage due to permanent deformation caused by excessive external force. The elasticity of the connection region can be enhanced by providing a plurality of columns or layers of first buffer cavities.

Further, the first buffer cavity is arranged in a single layer or multiple layers.

Further, the mounting assembly comprises a first fixing part and a second fixing part, wherein the first fixing part and the second fixing part are respectively arranged on the first mounting edge, and the first fixing part and the second fixing part are parallel; fixing convex blocks are arranged on the inner side or the outer side of the first fixing part and the second fixing part; the connecting area, the first mounting edge, the second mounting edge, the first fixing portion and the second fixing portion enclose a mounting groove with a concave section, wherein the connecting area is the bottom of the concave mounting groove, and the first mounting edge, the second mounting edge, the first fixing portion and the second fixing portion are two wing portions of the mounting groove.

Because the connecting area can deform to a certain extent, the first fixing part and the second fixing part can be easily unfolded in the construction process, so that the installation of the splice is facilitated. The block of the composite floor only needs to be provided with the clamping position or the clamping groove matched with the fixing convex block, the floor block is pressed downwards, the first buffer cavity is forced to extend to drive the first fixing part and the second fixing part to extend, the clamping position and the clamping groove can be buckled into the mounting groove, the mounting of the connecting piece is completed, and the construction difficulty of the composite floor is further reduced. And the mounting groove is only required to be pried open during disassembly, so that the clamping position or the clamping groove is separated from the fixing convex block, and the construction is rapid without damaging the composite floor or the connecting piece. The first and second mounting portions may be block-shaped bodies provided on the first and second mounting sides or bar-shaped or plate-shaped bodies extending along the first and second mounting sides.

Furthermore, a plurality of parallel connecting bridges are arranged between the first mounting edge and the second mounting edge, and the first mounting edge, the second mounting edge and the connecting bridges jointly enclose into the first buffer cavity.

Preferably, the method comprises the steps of: the first buffer cavity is at least one of parallelogram, circular arc, triangle, S-shaped, semicircle and ellipse.

The parallelogram, the circular arc shape and the S shape have stronger ductility and can be suitable for composite floors with larger thermal expansion coefficients. The circular arc semicircle and triangle have stronger structural stability, can more favorably lock two adjacent splice blocks, and are suitable for composite floors with smaller thermal expansion coefficient and requirement of tight combination between the splice blocks.

Preferably, the connecting bridge is of a linear structure, and an included angle between the connecting bridge and the first installation edge or the second installation edge is 10-90 degrees.

The linear connecting bridge which is not perpendicular to the first installation edge or the second installation edge can swing under the action of external force, the smaller the included angle between the connecting bridge and the first installation edge or the second installation edge is, the lower the constraint force on the first installation edge and the second installation edge is, and the formed first buffer cavity is easier to extend or compress under the action of external force. And vice versa. Therefore, when the linear connecting bridge is adopted, the strength and deformation performance of the whole connecting piece can be controlled by adjusting the angle of the connecting bridge so as to adapt to the requirements of different use environments, and the applicability of the invention is further improved. The simple structure is also beneficial to improving the durability and the reliability of the connecting piece, and simultaneously is beneficial to reducing the production cost of the connecting piece.

As an alternative embodiment, two adjacent connecting bridges are arranged parallel or axisymmetrically.

The invention also provides an anti-warping composite floor which comprises a plurality of spliced blocks with connected edges, wherein two adjacent spliced blocks are connected through the buffer type composite floor elastic connecting piece; the bottom of the edge of the block is provided with a fixing component for fixing the mounting component.

Preferably, the mounting assembly comprises a first fixing part and a second fixing part, wherein the first fixing part and the second fixing part are respectively arranged on the first mounting edge, and the first fixing part and the second fixing part are parallel; fixing convex blocks are arranged on the inner side or the outer side of the first fixing part and the second fixing part; the connecting area, the first mounting edge, the second mounting edge, the first fixing part and the second fixing part enclose a mounting groove with a concave section, wherein the connecting area is the bottom of the concave mounting groove, and the first mounting edge, the second mounting edge, the first fixing part and the second fixing part are two wing parts of the mounting groove; the fixing component comprises a main body horizontally extending from the edge of the splicing block and an L-shaped end part formed by downwards turning the tail end of the main body; the main body and the L-shaped end part jointly enclose a fixed groove which is positioned at the bottom of the edge of the splicing block and has a downward opening; a locking clamping groove matched with the fixing convex block is arranged in the fixing groove; two wings of the mounting groove are respectively wedged into the fixing grooves at the bottoms of the two adjacent splice blocks, so that the fixing protruding blocks are just clamped into the locking clamping grooves.

When the composite floor provided by the invention is subjected to volume shrinkage, the L-shaped end parts of the adjacent splice blocks are increased in distance to pull the connecting areas of the connecting pieces to extend, and the first fixing parts and the second fixing parts on the connecting pieces still maintain the state of being connected with the L-shaped end parts, so that the splice blocks can be effectively locked, and the splice blocks are prevented from loosening, seam pulling, sliding and displacement at the moment. When the composite floor expands, the connecting area is correspondingly compressed to avoid the separation of the first mounting part and the second mounting part from the L-shaped end part, and the composite floor is prevented from falling off, buckling and deforming. When the installation is carried out, the edges of two adjacent splice blocks are connected, the L-shaped end is pressed downwards to prop open the installation groove, and finally the fixing convex blocks on the inner side of the installation groove are clamped into the locking clamping grooves in the fixing groove. When the joint is disassembled, the joint of the two splice blocks is pried open by the practical hard object, so that the mounting groove of the connecting piece is expanded, the L-shaped end part embedded in the locking clamping groove can be taken out, the construction difficulty can be effectively reduced, and the construction efficiency can be improved. The connecting piece is completely shielded by the extended main body, so that the appearance of the composite floor is prevented from being influenced by the exposure of the connecting piece, and the applicability of the connecting piece is further improved. The position of the locking clamping groove in the fixing groove can be set according to the position of the fixing convex block, and the locking clamping groove can be realized by adopting the prior art and is not repeated.

Further, the bottommost end of the L-shaped end part is higher than the bottom of the mounting groove; the bottom surface of the connecting area is flush with the bottom surface of the splice.

Furthermore, a buffer gap with the width of 0.1-1mm is arranged between the two adjacent splice blocks.

The invention particularly sets a buffer gap with a certain width between two adjacent splice blocks, and when the volume of the splice blocks expands, the buffer gap can accommodate the expanded volume, thereby further preventing the problems of warping, arching and the like of the composite floor. And because the telescopic connecting piece exists in the composite floor, the splice blocks can be locked, so that the splice blocks can be kept stable and cannot slide and shift despite gaps.

Preferably, the tiles are regular polygons or irregular polygons.

In the present invention, the tiles may be arbitrary regular polygons or irregular polygons. Because of the telescopic elastic structure of the connecting piece, the splicing blocks with various shapes can be simply spliced and disassembled.
