Description

Technical Field

[0001] The present invention relates to the technical field of wallboard preparation, and in particular to a prefabricated tile exterior wall component and a preparation method thereof. Background Art

[0002] With the acceleration of industrialization, the construction industry has also begun to seek more efficient and precise construction methods. Against this background, prefabricated wall panels came into being. It adopts factory production and uses modern production processes and equipment to produce building materials with uniform specifications and reliable quality. Compared with traditional cast-in-place walls, prefabricated wall panels have many advantages. The production process of prefabricated wall panels is completed in the factory, which can ensure the stability of the production environment and the controllability of production quality. In the factory, prefabricated wall panels undergo precise mechanical processing and quality control to ensure that each wall panel meets the design requirements, thereby greatly improving the overall quality and stability of the building.

[0003] In the patent with the authorized patent name of a prefabricated exterior wall panel and the application number CN202110397294.6, it is proposed that after long-term use of the existing exterior wall panels, the adhesive joints between the various base panels are prone to brittleness, resulting in a decrease in the stability of the connection between the various base panels. The base panels are limited by the cooperation of the connecting rod and the limiting ring, thereby improving the stability of the connection between the various base panels in the prefabricated wall panel. The connecting rod and the limiting ring are used as a whole to reinforce the connection between the two substrates, but the connecting rod and the limiting rod do not have a tighter connection with the various substrates, but only play a reinforcement role. Once the threaded connection between the connecting rod and the limiting ring becomes loose, the two substrates will separate, and during the installation process, the limiting ring needs to be threadedly connected to the connecting rod separately in a certain order, and the installation steps are relatively complicated.

[0011] Preferably, the limiting structure includes two positioning holes, which are respectively opened on the upper surface and the lower surface of the connecting column, the internal threads of the positioning holes are connected to the positioning column, and the end of the positioning column away from the positioning hole is fixedly connected to the positioning block.

[0012] Preferably, a plurality of soft sharp-edged rings are integrally formed on the exterior of the connecting column.

[0013] The present invention also provides a method for preparing a prefabricated tile exterior wall component, comprising the following steps:

[0014] S1, injecting the plate material into the mold, setting a hole-forming part capable of expansion and contraction in the mold, waiting for the raw material injected into the mold to be formed and then contraction-forming the hole-forming part, and prefabricating the upper plate and the lower plate with through holes inside;

[0015] S2, applying an adhesive layer to opposite sides of the upper plate and the lower plate, connecting the upper plate and the lower plate by using the adhesive layer, and stacking the through holes in the upper plate and the lower plate during the bonding process, so that the through holes in the upper plate and the lower plate are connected;

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions 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 those skilled in the art without creative work are within the scope of protection of this application.

[0031] In the description of this application, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, "plurality" means two or more, unless otherwise clearly and specifically defined.

[0032] In the description of the present application, the term "for example" is used to mean "used as an example, illustration or description". Any embodiment described as "for example" in the present application is not necessarily to be construed as being more preferred or advantageous than other embodiments. The following description is given to enable any technician in the field to implement and use the present invention. In the following description, details are listed for the purpose of explanation. It should be understood that a person of ordinary skill in the art can recognize that the present invention can be implemented without using these specific details. In other examples, well-known structures and processes will not be elaborated in detail to avoid unnecessary details to obscure the description of the present invention. Therefore, the present invention is not intended to be limited to the embodiments shown, but is consistent with the widest scope consistent with the principles and features disclosed in the present application.

[0033] In the present invention, after the upper plate 101 and the lower plate 102 are glued together, the connecting column 104 is inserted into the inside of the through hole 103. When the connecting column 104 is inserted into the inside of the through hole 103, an inclined support point is formed, and the two through holes 103 and the connecting column 104 are arranged in an "eight" shape, which not only increases the contact area between the upper plate 101, the lower plate 102 and the connecting column 104, but also when the upper plate 101 and the lower plate 102 are separated, the connecting column 104 will form a plurality of abutment points inside the through hole 103. At the same time, when the wrapping shell 100 is wrapped around the outside of the upper plate 101 and the lower plate 102, the drying process of the raw material of the wrapping shell 100 can also make the upper thermosetting expansion ring 200, the middle thermosetting expansion ring 201 and the lower thermosetting expansion ring 202 located outside the connecting column 104 produce thermal expansion and curing effects, thereby further strengthening the connection stability between the upper plate 101 and the lower plate 102, and ensuring that the tiles will not separate during long-term use.

[0034] Embodiment 1

[0035] like Figure 1-Figure 4 As shown, the present application is a prefabricated tile exterior wall component, including a wrapping shell 100, an upper plate 101 and a lower plate 102, the upper plate 101 is located above the lower plate 102, the wrapping shell 100 wraps the upper plate 101 and the lower plate 102, a pair of through holes 103 are opened inside the upper plate 101 and the lower plate 102, connecting columns 104 are inserted into the through holes 103, multiple through holes 103 are obliquely opened inside the upper plate 101 and the lower plate 102, each pair of through holes 103 is arranged opposite to each other in an eight-shaped shape, an adhesive layer is bonded to the opposite side of the upper plate 101 and the lower plate 102, the connecting column 104 is inclined, the upper end and the lower end of the connecting column 104 are flush with the upper surface and the lower surface of the upper plate 101 respectively, and the connecting column 104 is movably connected with a limited position structure.

[0036] Specifically, during use, the staff places the lower plate 102 on the placement table. After placing the lower plate 102 on the placement table, the upper surface of the lower plate 102 is brushed with glue. After the brushing is completed, the upper plate 101 is placed on the lower plate 102, and the upper plate 101 is bonded with the adhesive layer brushed on the lower plate 102. During the bonding process of the upper plate 101 and the lower plate 102, it is necessary to ensure that the through holes 103 on the upper plate 101 and the lower plate 102 are flush.

[0037] Furthermore, after the upper plate 101 and the lower plate 102 are connected, the staff inserts the connecting column 104 into the through hole 103 opened on the outside of the upper plate 101 and the lower plate 102. The multiple through holes 103 opened on the outside of the upper plate 101 and the lower plate 102 together form an eight-shaped installation hole. At the same time, the inclined connecting column 104 is inserted into the through hole 103, so that the connecting column 104 can form more contact area with the upper plate 101 and the lower plate 102. Therefore, when a force of separation is generated between the upper plate 101 and the lower plate 102, the connecting column 104 will form multiple contact points inside the through hole 103. The generation of multiple contact points can prevent the upper plate 101 and the lower plate 102 from separating from each other.

[0038] like Figure 4-Figure 7 As shown, the inner wall diameter of the through hole 103 gradually decreases from top to bottom in a conical shape, the inner wall diameter of the through hole 103 located inside the upper plate 101 is larger than the inner wall diameter of the through hole 103 located inside the lower plate 102, the connecting column 104 is in an inclined cone shape, and the outer wall diameter of the connecting column 104 close to the upper plate 101 is larger than the outer wall diameter of the connecting column 104 close to the lower plate 102.

[0039] Specifically, during use, the staff first inserts the end of the connecting column 104 with a smaller diameter into the through hole 103 located inside the upper plate 101. During the plugging process, the hole diameter of the through hole 103 inside the upper plate 101 is larger, and the front end diameter of the connecting column 104 is smaller. Therefore, it is more convenient to insert the connecting column 104 with a smaller front end diameter into the through hole 103 with a larger hole diameter, and the plugging speed is faster.

[0040] Furthermore, when the connecting column 104 is fully inserted into the through hole 103 after the upper plate 101 and the lower plate 102 are spliced, because the through hole 103 after splicing is in an inclined cone shape, the connecting column 104 is also in an inclined cone shape, so when the end of the connecting column 104 with a smaller diameter at the bottom is fully inserted into the interior of the through hole 103, it can fill the smaller space at the bottom of the through hole 103, and the connecting column 104 with a larger diameter at the top will also remain in the corresponding space with a larger diameter of the through hole 103, thereby ensuring that the larger diameter part of the connecting column 104 at the top cannot pass through the space with a smaller aperture of the through hole 103, thereby avoiding the situation where the connecting column 104 slips out of the through hole 103 during long-term use.

[0041] Furthermore, the outer wall of the connecting column 104 and the inner wall of the through hole 103 are both rough surfaces. When the outer wall of the connecting column 104 and the interior of the through hole 103 are both rough surfaces, the friction between the through hole 103 and the connecting column 104 can be increased when the connecting column 104 is fully inserted into the interior of the through hole 103, thereby increasing the stability of the connecting column 104 inside the through hole 103 and preventing it from slipping out and falling easily, thereby further strengthening the connection stability of the connecting column 104 to the upper plate 101 and the lower plate 102.

[0042] like Figure 2-Figure 7 As shown, the limiting structure includes two positioning holes 402, which are respectively opened on the upper surface and the lower surface of the connecting column 104, the internal threads of the positioning holes 402 are connected to the positioning column 400, and the end of the positioning column 400 away from the positioning hole 402 is fixedly connected to the positioning block 401.

[0043] Specifically, during use, the limiting structure is used to ensure that the connecting column 104 will not be separated from the inside of the through hole 103. When the staff inserts the connecting column 104 into the inside of the through hole 103, the two positioning blocks 401 can be threadedly connected to the same positioning column 400 into the inside of the positioning hole 402, so as to connect the positioning block 401 and the connecting column 104. After the positioning block 401 is connected to the connecting column 104, the positioning blocks 401 connected at both ends can prevent the connecting column 104 from being separated from the inside of the through hole 103, and in the process of casting the wrapping shell 100, the mud can be clamped between the connecting column 104 and the positioning block 401 to form a wrapped clamping connection, thereby further increasing the overall stability of the wrapping shell 100, the upper plate 101 and the lower plate 102.

[0044] Furthermore, a plurality of soft sharp-edged rings 500 are integrally formed on the outside of the connecting post 104 . The arrangement of the plurality of soft sharp-edged rings 500 can assist in fixing the connecting post 104 inside the through hole 103 , thereby reducing the detachment phenomenon.

[0045] The technical solution in the above-mentioned embodiment of the present application has at least the following technical effects or advantages: relative to the prior art, in the present embodiment, the user inserts the connecting column 104 into the through hole 103 inside the upper plate 101 and the lower plate 102 respectively, and connects the upper plate 101 and the lower plate 102 through the combination of the through hole 103 and the connecting column 104, and increases the connection stability between the upper plate 101 and the lower plate 102 through the inclined through hole 103 and the connecting column 104, and provides multiple reverse contact points and resistance forces between the lower plate 102 and the upper plate 101 during the separation process through the inclined through hole 103 and the connecting column 104, thereby avoiding the separation of the upper plate 101 and the lower plate 102 and enhancing the connection stability between the upper plate 101 and the lower plate 102.

[0046] Embodiment 2

[0047] Considering that during use, when multiple connecting columns 104 are used alone to connect the upper plate 101 and the lower plate 102, although the existence of the connecting columns 104 will not cause the upper plate 101 and the lower plate 102 to separate, the adhesive between the upper plate 101 and the lower plate 102 will become brittle after long-term use, which will still cause a gap between the upper plate 101 and the lower plate 102. In view of the above technical problems, the present application proposes the following technical solutions to solve the above technical problems, specifically:

[0048] like Figure 3-Figure 6 As shown, the outer part of the connecting column 104 is integrally formed with an upper thermosetting expansion ring 200, a middle thermosetting expansion ring 201 and a lower thermosetting expansion ring 202, and the interior of the upper plate 101 and the lower plate 102 are provided with a plurality of positioning grooves 203, and the upper thermosetting expansion ring 200, the middle thermosetting expansion ring 201 and the lower thermosetting expansion ring 202 are parallel to the plurality of positioning grooves 203, respectively.

[0049] Specifically, during use, when the upper plate 101 and the lower plate 102 wrap the shell 100, in the process of wrapping the upper plate 101 and the lower plate 102 by the wrapping shell 100, the unformed wrapping shell 100 needs to be dried. During the drying process of the wrapping shell 100, the heat is transferred to the raw material of the wrapping shell 100, which will cause the wrapping shell 100 to dry and solidify. At the same time, the heat of drying the raw material of the wrapping shell 100 will be transferred to the inside of the upper plate 101 and the lower plate 102. After the heat is transferred to the inside of the upper plate 101 and the lower plate 102, the heat will continue to be transferred to the connecting column 104 and the upper thermosetting expansion ring 200. When the upper thermosetting expansion ring 200, the middle thermosetting expansion ring 201 and the lower thermosetting expansion ring 202 are heated, the upper thermosetting expansion ring 200, the middle thermosetting expansion ring 201 and the lower thermosetting expansion ring 202 are heated. The lower thermosetting expansion ring 202 will expand, and when the upper thermosetting expansion ring 200, the middle thermosetting expansion ring 201 and the lower thermosetting expansion ring 202 continue to expand, they will fill the interior of the positioning groove 203, and the expanded positioning groove 203 has a certain viscosity. The upper thermosetting expansion ring 200 with viscosity and expansion will adhere to the inner wall of the positioning groove 203, and when the wrapped shell 100 is cured, the drying device is removed for cooling. When the positioning groove 203 is cooled, the upper thermosetting expansion ring 200, the middle thermosetting expansion ring 201 and the lower thermosetting expansion ring 202 will be cured. The cured upper thermosetting expansion ring 200, the middle thermosetting expansion ring 201 and the lower thermosetting expansion ring 202 will cooperate with the positioning groove 203 to form a secondary connection between the upper plate 101 and the lower plate 102, thereby further increasing the connection stability between the upper plate 101 and the lower plate 102.

[0050] like Figure 5As shown, a sharp-edge groove 300 is integrally formed on the exterior of the positioning groove 203 .

[0051] Specifically, during use, through the setting of the sharp-edge groove 300, when the upper thermosetting expansion ring 200 is heated, it will expand. During the expansion of the upper thermosetting expansion ring 200, the middle thermosetting expansion ring 201 and the lower thermosetting expansion ring 202, the sharp edge of the sharp-edge groove 300 near the upper thermosetting expansion ring 200 points downward, while the sharp edge of the sharp-edge groove 300 near the lower thermosetting expansion ring 202 points upward. The sharp edges of the two sharp-edge grooves 300 facing upward and downward are arranged relatively to each other. Through the sharp-edge grooves 300 with sharp edges arranged relatively to each other, during the continuous expansion of the upper thermosetting expansion ring 200 and the lower thermosetting expansion ring 202, the expanding bodies will continue to enter the interior of the sharp-edge grooves 300 and form a clamping component again, thereby increasing the stability of the upper plate 101 and the lower plate 102.

[0052] Furthermore, when the expanded upper thermosetting expansion ring 200 continues to enter the interior of the sharp-edge groove 300, because two of the sharp-edge grooves 300 are arranged opposite to each other, the upper thermosetting expansion ring 200 continues to enter the interior of the sharp-edge groove 300, which pushes the upper plate 101 and the lower plate 102 closer to each other, thereby increasing the tight connection between the upper plate 101 and the lower plate 102.

[0053] The technical solution in the above-mentioned embodiment of the present application has at least the following technical effects or advantages: relative to the first embodiment, in the present embodiment, through the arrangement of multiple upper thermosetting expansion rings 200, during the drying process of the wrapped shell 100, the drying temperature will be transmitted to the upper thermosetting expansion ring 200, the middle thermosetting expansion ring 201 and the lower thermosetting expansion ring 202, when the upper thermosetting expansion ring 200, the middle thermosetting expansion ring 201 and the lower thermosetting expansion ring 202 receive the heat, which will cause the upper thermosetting expansion ring 200 to be heated. 00, the middle thermosetting expansion ring 201 and the lower thermosetting expansion ring 202 expand. When the upper thermosetting expansion ring 200, the middle thermosetting expansion ring 201 and the lower thermosetting expansion ring 202 expand, they will enter the interior of the positioning groove 203 to form a secondary connection. Through the setting of two sharp-edge grooves 300, during the expansion process of the upper thermosetting expansion ring 200 and the lower thermosetting expansion ring 202, they will relatively squeeze the upper plate 101 and the lower plate 102, thereby increasing the tight connection between the upper plate 101 and the lower plate 102.

[0054] Embodiment 3

[0055] Considering that in the drying process, the drying airflow is used to dry the package shell 100, and heat may be generated due to the obstruction of the upper plate 101 and the lower plate 102, which cannot be transmitted to the upper thermosetting expansion ring 200, the middle thermosetting expansion ring 201 and the lower thermosetting expansion ring 202 in time, in view of the above technical problems, the present application proposes the following technical solutions to solve the above technical problems, specifically:

[0056] Furthermore, iron powder is mixed inside the upper thermosetting expansion ring 200 , the middle thermosetting expansion ring 201 and the lower thermosetting expansion ring 202 .

[0057] Specifically, during use, the upper thermosetting expansion ring 200, the middle thermosetting expansion ring 201 and the lower thermosetting expansion ring 202 will expand and solidify after being heated, and in order to enhance the heating effect of the upper thermosetting expansion ring 200, the middle thermosetting expansion ring 201 and the lower thermosetting expansion ring 202 during the heating process, iron powder is added to the upper thermosetting expansion ring 200, the middle thermosetting expansion ring 201 and the lower thermosetting expansion ring 202. The addition of iron powder can not only increase the overall strength of the upper thermosetting expansion ring 200, the middle thermosetting expansion ring 201 and the lower thermosetting expansion ring 202 after expansion The body strength can also be improved, and the heating speed of the upper thermosetting expansion ring 200, the middle thermosetting expansion ring 201 and the lower thermosetting expansion ring 202 can be accelerated during the heating process. Because the heat conduction speed of iron powder is relatively fast, the heat in the drying process can be transferred to the upper thermosetting expansion ring 200, the middle thermosetting expansion ring 201 and the lower thermosetting expansion ring 202 under the isolation of the wrapping shell 100, the upper plate 101 and the lower plate 102, thereby accelerating the expansion speed of the upper thermosetting expansion ring 200, the middle thermosetting expansion ring 201 and the lower thermosetting expansion ring 202, and strengthening the expansion effect of the upper thermosetting expansion ring 200, the middle thermosetting expansion ring 201 and the lower thermosetting expansion ring 202.

[0058] Furthermore, the upper thermosetting expansion ring 200 , the middle thermosetting expansion ring 201 and the lower thermosetting expansion ring 202 are made of thermosetting resin, which will further solidify after thermal expansion to form a rigid connection, thereby ensuring the connection stability between the upper plate 101 and the lower plate 102 .

[0059] The technical solution in the above-mentioned embodiment of the present application has at least the following technical effects or advantages: by adding iron powder into the upper thermosetting expansion ring 200, the middle thermosetting expansion ring 201 and the lower thermosetting expansion ring 202, not only the heating effect is significantly enhanced, the expansion speed is increased, and the expansion effect is strengthened, but also the high thermal conductivity of the iron powder ensures that the heat in the drying process under the isolation of the wrapping shell 100, the upper plate 101 and the lower plate 102 can still be effectively transmitted to the upper thermosetting expansion ring 200, the middle thermosetting expansion ring 201 and the lower thermosetting expansion ring 202. In addition, thermosetting resin is used as the material of the upper thermosetting expansion ring 200, the middle thermosetting expansion ring 201 and the lower thermosetting expansion ring 202, which will be further cured after thermal expansion to form a rigid connection, thereby ensuring the connection stability of the upper plate 101 and the lower plate 102.

[0060] The present invention also provides a method for preparing a prefabricated tile exterior wall component, comprising the following steps:

[0061] S1, injecting the plate material into the mold, setting a hole-forming part capable of expansion and contraction in the mold, waiting for the raw material injected into the mold to be formed and then contraction-forming the hole-forming part, and prefabricating the upper plate 101 and the lower plate 102 with through holes 103 inside;

[0062] S2, applying an adhesive layer to opposite sides of the upper plate 101 and the lower plate 102, connecting the upper plate 101 and the lower plate 102 by using the adhesive layer, and stacking the through holes 103 in the upper plate 101 and the lower plate 102 during the bonding process, so that the through holes 103 in the upper plate 101 and the lower plate 102 are connected;
