Description

Technical Field

[0001] The utility model relates to the technical field of flooring, in particular to an anti-shrinkage component. Background Art

[0002] like Figure 1 As shown, the main structure of the composite floor in the prior art includes building materials, which are usually floor profiles. The top surface of the floor profile is covered with a composite layer made of polymer material. The composite layer can achieve the effects of pressure resistance, anti-slip and corrosion resistance of the composite floor, thereby meeting the requirements of permanence and surface aesthetics of the floor in different usage environments.

[0003] However, since the thermal expansion coefficients of polymer materials and metal alloys differ by several orders of magnitude, when used outdoors, when the ambient temperature drops, the shrinkage of the composite layer is much greater than that of the floor profile, that is, a large relative shrinkage occurs between the two, making the top edge of the floor profile easily exposed, resulting in the composite layer being unable to completely cover the floor profile. On the one hand, this reduces the aesthetics, and on the other hand, makes the top edge of the floor profile susceptible to corrosion damage, shortening the service life of the floor profile.

[0004] Therefore, it is necessary to improve the floor profiles in the prior art. Utility Model Content

[0005] The purpose of the utility model is to overcome the defects in the prior art and provide an anti-shrinkage component that can reduce the relative shrinkage to ensure the protection effect and extend the service life.

[0008] Preferably, in order to further reduce the relative shrinkage between the composite layer and the building material, two sides of the anti-shrinkage unit are flush with or closely adjacent to two sides of the paving surface.

[0010] Preferably, in order to increase the bonding strength between the composite layer and the anti-shrinkage strip, the recesses and the protrusions are spaced apart and arranged closely along the length direction of the anti-shrinkage strip.

[0011] Preferably, in order to increase the bonding strength between the composite layer and the anti-shrinkage strip, the anti-shrinkage strip is provided with depressions and / or protrusions distributed along its length.

[0012] Preferably, in order to increase the bonding strength between the composite layer and the anti-shrinkage strip, the paving surface is provided with a through groove extending along its length direction, and the anti-shrinkage strip is connected to the inner wall of the through groove.

[0013] Preferably, in order to strengthen the connection between the anti-shrinkage strip and the composite layer and prevent the composite layer from separating from the anti-shrinkage strip, the recess is in the shape of a through hole.

[0014] Preferably, in order to facilitate the molding of building materials and reduce production processes, the anti-shrinkage strip is integrally connected to the paving surface.

[0038] The following embodiments are used to further describe the specific embodiments of the present invention in conjunction with the accompanying drawings and examples. The following embodiments are only used to more clearly illustrate the technical solutions of the present invention and are not intended to limit the scope of protection of the present invention.

[0039] First embodiment

[0040] like Figure 2-Figure 2(B) As shown, the anti-shrinkage component of the first embodiment of the present invention includes a long strip of building material 1, the circumferential outer edge of the building material 1 includes a paving surface 11, the paving surface 11 is used to lay the composite layer 2, and an anti-shrinkage unit 3 is provided on the paving surface 11 to reduce the relative shrinkage of the composite layer 2 and the building material 1 after cooling. The two ends of the anti-shrinkage unit 3 are respectively flush with or close to the two ends of the paving surface 11, and the anti-shrinkage unit 3 includes an anti-shrinkage strip 31.

[0041] Specifically, the building material 1 of this embodiment is an aluminum alloy floor profile, the top surface of which is a paving surface 11, which is also a bearing surface for laying a composite layer 2 made of a polymer material. When the composite layer 2 is connected to the building material 1, the polymer material is laid on the paving surface 11 of the building material 1 in a molten state. After solidification and forming, a composite layer 2 is formed to achieve the effect of protecting the building material 1.

[0042] Since the anti-shrinkage strips 31 are provided on the paving surface 11, the contact area between the paving surface 11 and the composite layer 2 is increased, and the two ends of the anti-shrinkage unit 3 composed of the anti-shrinkage strips 31 are flush with the two ends of the paving surface 11, so that the two ends of the anti-shrinkage strips 31 can strengthen the bonding force between the ends of the composite layer 2 and the ends of the building material 1. After the use temperature is lowered, it can resist the relative shrinkage between the building material 1 and the composite layer 2, thereby ensuring that the composite layer 2 covers the building material 1, protects the building material 1, and extends the service life of the building material 1. Of course, the two ends of the anti-shrinkage strips 31 can also be close to the two ends of the paving surface 11 respectively, and the above-mentioned technical effects can also be achieved.

[0043] A further improvement is that the two sides of the anti-shrinkage unit 3 are flush with or immediately adjacent to the two sides of the paving surface 11. This structure increases the width of the anti-shrinkage unit 3, thereby increasing its anti-shrinkage coverage area. This reduces the relative shrinkage between the building material 1 and the composite layer 2 across the width of the building material 1, ensuring that the composite layer 2 can still cover and protect the building material 1 even at low temperatures.

[0044] In this embodiment, the two sides of the anti-shrinkage unit 3 are respectively adjacent to or closely adjacent to the two sides of the paving surface 11. To achieve this technical effect, at least two anti-shrinkage strips 31 are provided, distributed along the width direction of the paving surface 11. Specifically, two anti-shrinkage strips 31 are provided, which are respectively adjacent to the two sides of the building material 1, so that the anti-shrinkage unit 3 can also resist the shrinkage of the composite layer 2 relative to the building material 1 in the width direction, thereby ensuring the protective effect of the building material 1.

[0045] A further improvement is that the anti-shrinkage strip 31 is provided with depressions 311 and / or protrusions 312 distributed along its length direction.

[0046] Specifically, in this embodiment, the anti-shrinkage strip 31 is rack-shaped, that is, the tooth tip portion forms a protrusion 312, and the portion between the tooth tips forms a recess 311. With this design, after the composite layer 2 is covered on the paving surface 11, the molten polymer material enters the recess 311 portion, ultimately increasing the contact area between the composite layer 2 and the anti-shrinkage strip 31. At the same time, the tooth tip portion, that is, the protrusion 312 portion, is embedded in the anti-shrinkage strip 31, further strengthening the binding force of the anti-shrinkage strip 31.

[0047] A further improvement is that the anti-shrinkage strip 31 extends along the length direction of the paving surface 11 ; the recesses 311 and the protrusions 312 are spaced apart and arranged closely along the length direction of the anti-shrinkage strip 31 .

[0048] After adopting the above structure, during the production process of the building material 1, the anti-shrinkage strip 31 is integrally connected to the paving surface 11. After the building material 1 is extruded, pressure is applied to the top of the anti-shrinkage strip 31 using a pressure roller with evenly distributed convex patterns on the surface, so that the convex patterns are squeezed on the anti-shrinkage strip 31 to form a depression 311. At the same time, a protrusion 312 is formed between two adjacent depressions 311, and finally a one-time molded product as shown in the figure can be formed.

[0049] Second embodiment

[0050] like Figure 3-Figure 3(B) As shown, the anti-shrinkage component of the second embodiment of the present invention is based on the first embodiment, with the difference that the cross-section of the anti-shrinkage strip 31 is L-shaped, and the two anti-shrinkage strips 31 are arranged back to back, and the protrusion 312 and the recess 311 are distributed at the end of the anti-shrinkage strip 31 away from the paving surface 11.

[0051] Compared with the first embodiment, in this embodiment, the shape of the anti-shrinkage strip 31 is changed, and the distribution direction of the recess 311 and the protrusion 312 is changed, which is beneficial to increase the depth of the protrusion 312 and the recess 311, thereby increasing the contact area between the composite layer 2 and the anti-shrinkage strip 31, and strengthening the bonding strength between the composite layer 2 and the anti-shrinkage strip 31, thereby achieving the effect of further resisting the relative shrinkage of the composite layer 2 and the paving surface 11.

[0052] Third embodiment

[0053] like Figure 4 and Figure 4 As shown in (A), the anti-shrinkage component of the third embodiment of the present invention is based on the first embodiment, with the difference that a through groove 111 extending along its own length direction is provided on the paving surface 11, and the anti-shrinkage strip 31 is connected to the inner wall of the through groove 111.

[0054] Two through grooves 111 are provided on the paving surface 11, and the through grooves 111 correspond to the anti-shrinkage strips 31 one by one, and the anti-shrinkage strips 31 are connected to the inner walls of the through grooves 111. This is conducive to truly increasing the height of the anti-shrinkage strips 31, and then increasing the depth of the recesses 311 and the protrusions 312 on the anti-shrinkage strips 31, thereby increasing the contact area between the composite layer 2 and the anti-shrinkage strips 31, and strengthening the bonding strength between the composite layer 2 and the anti-shrinkage strips 31, thereby achieving a technical effect similar to that of the second embodiment.

[0055] Fourth embodiment

[0056] like Figure 5 and Figure 5 As shown in (A), the anti-shrinkage component of the fourth embodiment of the present invention is based on the third embodiment, with the difference that the through groove 111 is located between the paving surface 11 and the side surface of the building material 1.

[0057] After adopting the above design, the through groove 111 is located on the outside of the building material 1, which can also increase the height of the anti-shrinkage strip 31, and then increase the depth of the protrusion 312 and the recess 311, so as to increase the contact area between the anti-shrinkage strip 31 and the composite layer 2, strengthen the bonding force, and reduce the relative shrinkage between the composite layer 2 and the building material 1 when the temperature drops.

[0058] Fifth embodiment

[0059] like Figure 6-Figure 6(B) As shown, the anti-shrinkage component of the fifth embodiment of the present invention is based on the first embodiment, with the difference that the anti-shrinkage strip 31 is provided with recesses 311 spaced apart along its length direction, the recesses 311 are through-hole shaped, and the two openings of the recesses 311 are respectively located on both sides of the anti-shrinkage strip 31.

[0060] After using the above structure, the high-temperature polymer material is in a molten state and is laid on the paving surface 11. Part of the polymer material enters the through-hole-shaped recess 311, connecting the parts on both sides of the anti-shrinkage strip 31 together, thereby enhancing the bonding strength between the composite layer 2 and the paving surface 11. At the same time, it can also prevent the composite layer 2 from separating from the paving surface 11, further achieving a good protective effect on the building material 1.

[0061] Sixth embodiment

[0062] like Figure 7-Figure 7(B) As shown, the anti-shrinkage component of the sixth embodiment of the present invention is based on the first embodiment, with the difference that the anti-shrinkage strip 31 includes a turning section 313 , and the extension direction of the turning section 313 has an angle with the length direction and the width direction of the paving surface 11 .

[0063] Specifically, the anti-shrinkage strip 31 of this embodiment is formed by integrally connecting spaced straight segments and redirecting segments 313. The straight segments extend parallel to the length of the building material 1, while the redirecting segments 313 are arc-shaped, forming an angle between their extension and both the length and width of the paving surface 11. After the anti-shrinkage strip 31 is applied, when the polymer material is placed on the paving surface 11 and covers both the paving surface 11 and the anti-shrinkage strip 31, the redirecting segments 313 can inhibit shrinkage of the polymer composite layer 2 relative to the building material 1 in both the length and width directions during a temperature drop, ensuring that the composite layer 2 covers the paving surface 11 and effectively protects the building material 1.

[0064] It should be noted that, after the building material 1 of this embodiment is extruded by the extruder, the eccentric wheel applies pressure to the side of the anti-shrinkage strip 31 , so that spaced straight segments and direction-changing segments 313 are formed on the anti-shrinkage strip 31 .

[0065] Seventh embodiment

[0066] like Figure 8 As shown, the anti-shrinkage assembly of the seventh embodiment of the present invention is based on the first embodiment, with the difference that the anti-shrinkage strips 31 are cross-distributed on the paving surface 11 in a mesh shape.

[0067] In this embodiment, the mesh anti-shrinkage strips 31 can also suppress the relative shrinkage of the composite layer 2 relative to the building material 1 during cooling, thereby achieving a good protective effect. The anti-shrinkage strips 31 can be fixed to the laying surface 11 of the building material 1 by welding.

[0068] Eighth embodiment

[0069] like Figure 9 As shown, the anti-shrinkage component of the eighth embodiment of the present invention is based on the seventh embodiment, with the difference that four anti-shrinkage strips 31 are provided, which are adjacent to the four corners of the paving surface 11 respectively, and the extension direction of the anti-shrinkage strips 31 has an angle with the length direction and the width direction of the paving surface 11.

[0070] After adopting the above structure, the anti-shrinkage strips 31 at the four corners of the paving surface 11 can tension the composite layer 2 when the temperature drops to suppress the relative shrinkage of the composite layer 2, ensuring that the composite layer 2 covers the building material 1. Compared with the seventh embodiment, the amount of anti-shrinkage strips 31 is saved, the cost is reduced, and the weight of the component can be reduced, which is convenient for transportation and installation.

[0071] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
