Description

Technical Field

[0001] This application relates to the field of insulation boards, and in particular to a method for assembling a lightweight composite insulation board that does not require reversing. Background Technology

[0002] Insulation boards, simply put, are boards used for insulating buildings. They are rigid foam plastic boards made from polystyrene resin as the main raw material, along with other raw materials and polymers. The mixture is heated and mixed while a catalyst is injected, and then extruded and molded. They have moisture-proof and waterproof properties, allowing for a reduction in the thickness of the building's external envelope, thereby increasing the usable indoor area.

[0003] In the existing technology, the assembly of insulation boards typically involves setting one end of the insulation board into a groove and the other end into a protrusion, matching the two to complete the assembly. During construction, when the same ends of two insulation boards are aligned, installation becomes difficult, requiring reversal and adjustment so that the grooved end is aligned with the protruding end for installation. However, the common sizes of insulation boards used in buildings are 1200*600*100mm and 2000*1000*100mm, which are relatively large. The reversal requires a large range of operations, increasing the difficulty of the work and affecting the overall installation efficiency. Summary of the Invention

[0004] The purpose of this application is to eliminate the need for reversing operations, thereby reducing the operational scope and improving installation efficiency. Compared with existing technologies, it provides a method for assembling lightweight composite insulation boards without reversing, including the following steps:

[0005] S1. Take two boards with quick-installation flexible strips at the construction site, align the ends of the boards, and make the hemispherical grooves on the two boards fit together to form a limiting groove.

[0006] S2. Tear off the quick-release flexible strip. After it loses its adhesive binding to the board, it exhibits the property of being able to bend independently. Insert the two ends of the quick-release flexible strip into the limiting grooves formed by the splicing of hemispherical grooves on the two boards respectively.

[0007] S3. Inject silicone sealant into the quick-install flexible strip in several stages:

[0008] S31. First injection of sealant: Inject glass sealant into the cavity through the injection tube until the pre-bulging piece bulges upwards and then stop injecting sealant.

[0009] S32. Second injection of adhesive: Press down on the bulging pre-bulging piece multiple times to press the glass glue inside into the locking strip. When the pre-bulging piece returns to its original shape after you stop pressing, perform the second injection of adhesive until the pre-bulging piece bulges up obviously and then stop the injection.

[0010] S33. Repeat step S32 continuously. When the pre-drum plate is difficult to return to its original state after multiple presses, stop the glue injection and seal the glue injection tube.

[0011] By designing grooves at both ends of the panel and incorporating quick-release flexible strips for installation assistance, the two panels are assembled with identical ends. Assembly is achieved by embedding the quick-release flexible strips into the two panels. After assembly, silicone sealant is saturated into the quick-release flexible strips, gradually reducing their flexibility and solidifying their shape, thus locking the two adjacent panels together. Compared to existing technologies, this eliminates the need to consider the alignment of the grooved and protruding ends, effectively avoiding the need for reversing operations when the same ends are facing each other. This reduces the operational range during panel installation, significantly improving installation efficiency. Furthermore, due to the flexibility of the quick-release flexible strips, the operating space for one worker is effectively reduced when they are inserted between two panels, allowing multiple workers to perform assembly work simultaneously in the same area, further improving assembly efficiency.

[0012] Optionally, hemispherical grooves are chiseled at both the left and right outer ends of the plate. The quick-installation flexible strip is bonded to the end of the plate where the hemispherical groove is not chiseled, and the length of the quick-installation flexible strip is consistent with the length of the hemispherical groove, so that after the quick-installation flexible strip is embedded in the two plates, the ends of the two plates that are close to each other can be completely connected.

[0013] Optionally, the quick-release flexible strip includes a bending limiting strip located in the middle and two locking strips fixedly connected to the left and right ends of the bending limiting strip. The upper end of the bending limiting strip has a groove, and an injection tube is fixedly embedded at the bottom of the groove. The bending limiting strip has a cavity inside, and multiple evenly distributed glue passage holes are carved on the left and right inner walls of the cavity. The glue passage holes connect the cavity and the locking strip. Multiple lightweight hard balls are placed inside the locking strip. The arrangement of multiple lightweight hard balls can effectively improve the overall strength of the locking strip, making the quick-release flexible strip more effective in assisting the connection between the two plates.

[0014] Optionally, the glue injection tube communicates with the cavity, and the upper end of the glue injection tube is flush with the top of the bending limit strip, so that the glue injection tube is not easy to protrude from the groove opening and is not easy to affect the splicing of multiple panels.

[0015] Optionally, the multiple adhesive holes are located between two adjacent lightweight hard balls. The diameter of the lightweight hard ball is smaller than the diameter of the locking strip, and the difference between their diameters is no more than 1 / 4 of the diameter of the lightweight hard ball. This makes it difficult for the multiple lightweight hard balls to be arranged side by side laterally, and the longitudinal misalignment is also not significant. In addition, the diameter of the lightweight hard ball is larger than the distance at the opening of the hemispherical groove, so that the locking strip is difficult to fall off after being embedded in the hemispherical groove, thereby effectively ensuring the connection strength between the two.

[0016] Optionally, the bending limiter includes multiple rigid shaping sections and elastic sections fixedly connected between two adjacent shaping sections. When the quick-installation flexible strip is not embedded between the two plates, the elastic sections give the quick-installation flexible strip a certain degree of flexibility, thus making its distribution range relatively small. This allows more workers to assemble it simultaneously on the construction site, thereby improving installation efficiency. The height of the shaping section is 3-5 times that of the elastic section, effectively ensuring the strength of the bending limiter. When the bending limiter is embedded in two hemispherical grooves at the same time, the hemispherical grooves restrain it, making it difficult to bend under the action of the shaping sections, resulting in high strength and maintaining the stability of the connection between the two plates. The upper and lower ends of the locking strip are rigid structures, facilitating the entry of its ends into the groove from the limiting part, reducing the difficulty of assembly. The longitudinal end face of the locking strip is made of flexible sealing material. When silicone sealant is injected, the sealant causes it to bulge to a certain extent, thereby squeezing the quick-installation flexible strip into contact with the inner wall of the hemispherical groove, further improving the connection strength.

[0017] Optionally, a pre-bulging plate is fixedly connected to the end face of the locking strip near the groove. A through hole is drilled on the top of the locking strip, and the pre-bulging plate communicates with the locking strip through the through hole. The pre-bulging plate is an elastic sealing structure. When no glass glue is injected, the pre-bulging plate is attached to the surface of the locking strip. When glass glue is injected, the pre-bulging plate can expand after the glass glue enters into the pre-bulging plate. The expansion and change of the pre-bulging plate can effectively determine the injection status of glass glue in the quick-install flexible strip.

[0018] Optionally, in steps S31 and S32, the glue injection tube is kept blocked each time the pre-drum piece is pressed; after the glue injection is finished in step S33 and before the glue injection tube is blocked, the glue injection tube is opened first, and the pre-drum piece is pressed slowly so that the excess glass glue is squeezed out from the glue injection tube and overflows into the groove. After the pre-drum piece is reattached to the surface of the locking strip, the glue injection tube is blocked.

[0019] Compared to existing technologies, the advantages of this application are:

[0020] (1) By setting both ends of the board body into grooves and setting quick-installation flexible strips for installation assistance, the ends of the two boards are the same during assembly. The assembly is achieved by embedding the quick-installation flexible strips into the two boards. After assembly, glass glue is saturated into the quick-installation flexible strips, thereby gradually reducing their flexibility and gradually fixing their shape, thereby locking the two adjacent boards together. Compared with the prior art, there is no need to consider the situation where the groove end and the protruding end are opposite, thus effectively avoiding the need to change the direction when the same end is opposite, thereby reducing the operation range during board installation and greatly improving the installation efficiency. In addition, due to the flexibility of the quick-installation flexible strips, when they are inserted between the two boards, the operating space of one worker can be effectively reduced, thereby allowing multiple workers to perform assembly work in the same area at the same time, further improving the assembly efficiency.

[0021] (2) Hemispherical grooves are chiseled at both the left and right outer ends of the board. The quick-installation flexible strip is attached to the end of the board where the hemispherical groove is not chiseled, and the length of the quick-installation flexible strip is consistent with the length of the hemispherical groove, so that after the quick-installation flexible strip is embedded in the two boards, the ends of the two boards that are close to each other can be completely connected.

[0022] (3) The setting of multiple lightweight hard balls can effectively improve the overall strength of the locking strip and make the quick-release flexible strip more effective in assisting the connection between the two plates.

[0023] (4) The glue injection tube is connected to the cavity, and the upper end of the glue injection tube is flush with the top of the bending limit strip, so that the glue injection tube is not easy to protrude from the groove opening and is not easy to affect the splicing of multiple boards.

[0024] (5) Multiple glue holes are located between two adjacent lightweight hard balls. The diameter of the lightweight hard ball is smaller than the diameter of the locking strip, and the difference between the two diameters is no more than 1 / 4 of the diameter of the lightweight hard ball. This makes it difficult for multiple lightweight hard balls to be arranged side by side laterally, and the longitudinal misalignment is also not large. In addition, the diameter of the lightweight hard ball is larger than the distance at the opening of the hemispherical groove. After the locking strip is embedded in the hemispherical groove, it is difficult to fall off, thus effectively ensuring the connection strength between the two.

[0025] (6) The bending limit strip includes multiple rigid shaping sections and elastic sections fixedly connected between two adjacent shaping sections. When the quick-install flexible strip is not embedded between the two plates, the elastic section makes the quick-install flexible strip have a certain degree of bendable elasticity, thus making its distribution range relatively small, allowing more workers to assemble at the construction site at the same time, thereby improving installation efficiency. The height of the shaping section is 3-5 times that of the elastic section, effectively ensuring the strength of the bending limit strip. When the bending limit strip is embedded in two hemispherical grooves at the same time, due to the constraint of the hemispherical grooves, it is difficult to bend under the action of the shaping section, and has high strength, thereby maintaining the stability of the connection between the two plates. The upper and lower ends of the locking strip are rigid structures, which facilitates the entry of its ends into its interior from the limiting groove opening, reducing the difficulty of assembly. The longitudinal end face of the locking strip is made of flexible sealing material. When glass glue is injected, the glass glue can cause it to bulge to a certain extent, thereby making the quick-install flexible strip squeeze into contact with the inner wall of the hemispherical groove, further improving the connection strength.

[0026] (7) A pre-drum plate is fixedly connected to the end face of the locking strip near the groove. A through hole is drilled on the top of the locking strip. The pre-drum plate communicates with the locking strip through the through hole. The pre-drum plate is an elastic sealing structure. When no glass glue is injected, the pre-drum plate is attached to the surface of the locking strip. When glass glue is injected, the pre-drum plate can bulge after the glass glue enters into the pre-drum plate. Based on the bulging change of the pre-drum plate, the injection status of glass glue in the quick-install flexible strip can be effectively judged. Attached Figure Description

[0038] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application. Example

[0039] This application discloses a method for assembling a lightweight composite insulation board without reversing direction. Please refer to [link / reference]. Figure 1 This includes the following steps:

[0040] S1, such as Figure 2-3Take two boards 1 with quick-installation flexible strips 2 at the construction site, align the ends of the boards, and make the hemispherical grooves 11 on the two boards 1 fit together to form a limiting groove. Hemispherical grooves 11 are chiseled on the left and right outer ends of the boards 1. The quick-installation flexible strips 2 are glued to the ends of the boards 1 that are not chiseled with hemispherical grooves 11, and the length of the quick-installation flexible strips 2 is consistent with the length of the hemispherical grooves 11, so that after the quick-installation flexible strips 2 are embedded in the two boards 1, the ends of the two boards 1 that are close to each other can be completely connected.

[0041] S2. Tear off the quick-release flexible strip 2. After it loses its adhesive binding to the board 1, it exhibits the ability to bend independently. Insert the two ends of the quick-release flexible strip 2 into the limiting grooves formed by the hemispherical grooves 11 on the two boards respectively.

[0042] S3, such as Figure 6 Inject glass glue into the quick-install flexible strip 2 in several stages:

[0043] S31. First injection of sealant: Inject glass sealant into the cavity through the injection tube 42 until the pre-bulging piece 6 bulges upwards and then stop the injection.

[0044] S32. Second injection of adhesive: Press down on the bulging pre-drum plate 6 multiple times to press the glass adhesive inside into the locking strip 22. When the pre-drum plate 6 returns to its original state after the pressing stops, perform the second injection of adhesive until the pre-drum plate 6 bulges up significantly and then stop the injection of adhesive.

[0045] S33. Repeat step S32 continuously. When the pre-drum plate 6 is difficult to return to its original state after multiple presses, stop the glue injection and seal the glue injection tube 42.

[0046] Please see Figure 4-5 The quick-install flexible strip 2 includes a bending limiting strip 21 located in the middle and two locking strips 22 respectively fixedly connected to the left and right ends of the bending limiting strip 21. A groove 41 is chiseled at the upper end of the bending limiting strip 21, and an injection tube 42 is fixedly embedded at the bottom of the groove 41. Figure 6-7 The bending limiter 21 has a cavity inside, and multiple evenly distributed glue holes 5 are drilled on the left and right inner walls of the cavity. The glue holes 5 connect the cavity and the locking strip 22. Multiple lightweight hard balls 3 are placed inside the locking strip 22. The setting of multiple lightweight hard balls 3 can effectively improve the overall strength of the locking strip 22, making the quick-release flexible strip 2 better at assisting the connection between the two plates 1.

[0047] The glue injection tube 42 communicates with the cavity, and the upper end of the glue injection tube 42 is flush with the top of the bending limit strip 21, so that the glue injection tube 42 is not easy to protrude from the opening of the groove 41 and is not easy to affect the splicing of multiple plates 1; multiple glue holes 5 are located between two adjacent lightweight hard balls 3. The diameter of the lightweight hard ball 3 is smaller than the diameter of the locking strip 22, and the difference between the two diameters is not greater than 1 / 4 of the diameter of the lightweight hard ball 3, so that multiple lightweight hard balls 3 are not easy to be side by side laterally, and the longitudinal misalignment is not large. In addition, the diameter of the lightweight hard ball 3 is larger than the distance of the opening of the hemispherical groove 11, so that the locking strip 22 is difficult to fall off after being embedded in the hemispherical groove 11, thus effectively ensuring the connection strength between the two.

[0048] Please see Figure 4 The bending limit strip 21 includes multiple rigid shaping sections and elastic sections fixedly connected between two adjacent shaping sections. When the quick-install flexible strip 2 is not embedded between the two plates 1, the elastic sections give the quick-install flexible strip 2 a certain degree of bendability, thus making its distribution range relatively small. This allows more workers to assemble it simultaneously on the construction site, thereby improving installation efficiency. The height of the shaping section is 3-5 times that of the elastic section, effectively ensuring the strength of the bending limit strip 21. When the bending limit strip 21 is embedded in the two hemispherical grooves 11 at the same time, the hemispherical grooves 11 restrain it, and the shaping sections make it difficult to bend, giving it high strength and maintaining the stability of the connection between the two plates 1. The upper and lower ends of the locking strip 22 are rigid structures, making it easy for its ends to enter the interior from the limiting groove opening, reducing the difficulty of assembly. The longitudinal end face of the locking strip 22 is made of flexible sealing material. When silicone sealant is injected, the sealant can cause it to bulge to a certain extent, thereby making the quick-install flexible strip 2 press against the inner wall of the hemispherical groove 11, further improving the connection strength.

[0049] Additionally, it is worth noting that when the flexible part of the locking strip 22 is fully inflated, its diameter is greater than the diameter of the arc-shaped section of the hemispherical groove 11, and the dimensions of the bending limit strip 21 are consistent with the dimensions of the rectangular section of the hemispherical groove 11.

[0050] Please see Figure 8 A pre-drum plate 6 is fixedly connected to the end face of the locking strip 22 near the groove 41. A through hole is drilled on the top of the locking strip 22, and the pre-drum plate 6 communicates with the locking strip 22 through the through hole. The pre-drum plate 6 is an elastic sealing structure. When no glass glue is injected, the pre-drum plate 6 is attached to the surface of the locking strip 22. When glass glue is injected, the pre-drum plate 6 can expand after the glass glue enters into the pre-drum plate 6. According to the expansion change of the pre-drum plate 6, the injection status of glass glue in the quick-install flexible strip 2 can be effectively judged.

[0051] In steps S31 and S32, each time the pre-drum plate 6 is pressed, the glue injection tube 42 is kept in a blocked state. After the glue injection is completed in step S33 and before the glue injection tube 42 is blocked, the glue injection tube 42 is opened first, and the pre-drum plate 6 is pressed slowly so that the excess glass glue is squeezed out from the glue injection tube 42 and overflows into the groove 41. After the pre-drum plate 6 is reattached to the surface of the locking strip 22, the glue injection tube 42 is blocked.

[0052] By designing both ends of the panel with grooves and incorporating a quick-release flexible strip 2 for installation assistance, the two panels are aligned during assembly. Assembly is achieved by embedding the quick-release flexible strip 2 into the two panels. After assembly, silicone sealant is saturated into the quick-release flexible strip 2, gradually reducing its flexibility and solidifying its shape, thus locking the two adjacent panels together. Compared to existing technologies, this eliminates the need to consider the alignment of the grooved and protruding ends, effectively avoiding the need for reversing operations when the same ends are aligned. This reduces the operational range during panel installation, significantly improving installation efficiency. Furthermore, due to the flexibility of the quick-release flexible strip 2, inserting it between two panels effectively reduces the operating space for one worker, allowing multiple workers to perform assembly work simultaneously in the same area, further improving assembly efficiency.

[0053] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and its improved concept, should be covered within the scope of protection of this application.
