Description

Technical Field

[0001] This invention belongs to the field of terracotta panel curtain wall technology, specifically relating to a semi-open joint construction method for terracotta panel curtain wall sealant. Background Technology

[0002] Currently, terracotta panel curtain walls are being widely adopted in public buildings such as cultural activity centers and schools across the country, especially in cities in southern China where they are prioritized for the facade decoration of public buildings. However, current terracotta panel curtain wall construction has not effectively addressed the color difference caused by reflection between the sealant at the panel joints and the terracotta panels. Most terracotta panel curtain walls currently use a fully open-joint design (i.e., no sealant applied), or, as a last resort, dark-colored sealant and dark-colored terracotta panels are used, sacrificing the facade effect. Others use sealant of the same color as the terracotta panels, allowing the color difference caused by reflection to persist, significantly reducing the aesthetic appeal of the building's facade.

[0003] Therefore, it is necessary to provide a semi-open joint construction method for terracotta panel curtain wall sealant, which can control the surface height of the sealant to be consistent, thereby improving the construction efficiency and overall aesthetics of terracotta panel curtain walls. Summary of the Invention

[0004] The purpose of this invention is to provide a semi-open joint construction method for sealant on terracotta panel curtain walls, so as to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a semi-open joint construction method for sealant of terracotta panel curtain wall, including terracotta panels, connectors and joint closing tools, wherein the terracotta panels are provided with recessed texture lines and protruding texture lines on the left side, and the terracotta panels are arranged in six groups, distributed in three rows and two columns, and adjacent groups of terracotta panels are fixedly connected by connectors.

[0006] A vertical seam is formed between two adjacent sets of terracotta panels in the horizontal direction, and a horizontal seam is formed between two adjacent sets of terracotta panels in the vertical direction;

[0007] The horizontal and vertical seams are filled with foam strips, and then sealant is applied to the foam strips.

[0008] The present invention further describes that the seam closing tool includes a seam closing plate and a movable block. The top of the movable block has a through groove, and the seam closing plate is disposed in the through groove. The top of the seam closing plate is arc-shaped and has teeth. The seam closing plate and the movable block have mounting holes. There are two sets of mounting holes. Fasteners are disposed in the mounting holes. The seam closing plate and the movable block are connected into a whole by fasteners.

[0009] The present invention further describes that the movable block has a first movable groove inside, a first protrusion is fixedly connected to the bottom of the movable block, a transparent limiting plate and a connecting post are sleeved on the outside of the movable block, the transparent limiting plate is fixedly connected to the top of the connecting post, a second movable groove is opened inside the connecting post, the second movable groove matches the cross-sectional size of the first protrusion, a second protrusion is fixedly connected to the top of the connecting post, and the protrusion height of the second protrusion is the same as that of the first protrusion.

[0010] The present invention further illustrates that a handle is fixedly connected to the bottom of the connecting column, and a groove is provided at the center of the bottom of the handle.

[0011] The present invention further illustrates that the cross-sections of the movable block, the first movable groove, and the second movable groove are all rectangular.

[0012] The present invention further illustrates that a slider is provided in the first movable groove, the slider is connected to a hexagonal socket head cap screw rod by a bearing, the hexagonal socket head cap screw rod passes through the bottom of the movable block and is threadedly connected to the movable block, the hexagonal socket head cap screw rod passes through the handle and is rotatably connected to the handle, and the bottom of the hexagonal socket head cap screw rod is provided in the groove.

[0013] The present invention further illustrates that the semi-open joint construction method of the terracotta panel curtain wall sealant includes the following steps:

[0014] Step 1: Assemble the terracotta slab template according to the thickness of the terracotta slab;

[0015] Step 2: Determine the depth of the semi-open seam sealant and the protruding texture lines, as well as the width of the horizontal and vertical seams. Fill the horizontal and vertical seams to form the semi-open seam sealant surface layer.

[0016] Step 3: Make the seam-sealing tool;

[0017] Step 4: Perform the seam sealing work.

[0018] The present invention further explains that, specifically, the sewing tool manufacturing process includes the following steps:

[0019] Step 3 - (a): Make a seam-sealing board according to the width of the horizontal and vertical seams, so that the width of the seam-sealing board is consistent with the width of the horizontal and vertical seams, and make teeth on the top of the seam-sealing board;

[0038] The following detailed, non-limiting description of the technical solution of the present invention, in conjunction with preferred embodiments and accompanying drawings, is provided. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0039] like Figure 1 and Figure 2 As shown, the present invention provides a technical solution: a semi-open joint construction method for sealant on terracotta panel curtain walls, including terracotta panels 1, connectors 8 and joint closing tools. The terracotta panels 1 have recessed texture lines 6 and protruding texture lines 7 on the left side, which can enhance the aesthetics of the curtain wall facade. There are six groups of terracotta panels 1 arranged in three rows and two columns. Adjacent groups of terracotta panels 1 are fixedly connected by connectors 8 to form a whole.

[0040] It should be noted that connector 8 is an existing device.

[0041] A vertical joint 3 is formed between two adjacent sets of terracotta slabs 1 in the horizontal direction, and a horizontal joint 2 is formed between two adjacent sets of terracotta slabs 1 in the vertical direction.

[0042] The horizontal joint 2 and the vertical joint 3 are filled with foam strips 5, and then sealant 4 is filled on the foam strips 5 to form a semi-open sealant surface layer, which can improve the sealing performance of the terracotta panel curtain wall.

[0043] like Figure 1 , Figure 3 , Figure 4 , Figure 7 and Figure 8As shown, the seam closing tool includes a seam closing plate 9 and a movable block 10. The top of the movable block 10 has a through groove 12, and the seam closing plate 9 is disposed in the through groove 12. The top of the seam closing plate 9 is arc-shaped and has teeth 11. The seam closing plate 9 and the movable block 10 have mounting holes 13. There are two sets of mounting holes 13. Fasteners 14 are disposed in the mounting holes 13. The fasteners 14 can be bolts and nuts. The seam closing plate 9 and the movable block 10 are connected into a whole by the fasteners 14.

[0044] The movable block 10 has a first movable groove 15 inside, and a first protrusion 16 is fixedly connected to the bottom of the movable block 10. A transparent limiting plate 17 and a connecting post 18 are sleeved on the outside of the movable block 10. The transparent limiting plate 17 is fixedly connected to the top of the connecting post 18. A second movable groove 20 is opened inside the connecting post 18. The cross-sectional dimensions of the second movable groove 20 match those of the first protrusion 16. A second protrusion 19 is fixedly connected to the top of the connecting post 18. The protrusion height of the second protrusion 19 is the same as that of the first protrusion 16, so that the movable block 10 is slidably connected to the connecting post 18 and the transparent limiting plate 17.

[0045] A handle 21 is fixedly connected to the bottom of the connecting post 18. A groove 22 is provided in the center of the bottom of the handle 21. The seam closing plate 9 is vertically inserted into the horizontal seam 2 and the vertical seam 3. The top of the transparent limiting plate 17 is attached to the protruding texture line 7. The teeth 11 of the seam closing plate 9 are adjusted to be parallel to the direction of the horizontal seam 2 and the vertical seam 3. The seam closing tool is driven to slide on the clay plate 1 by the handle 21, that is, the seam closing plate 9 is driven to slide in the horizontal seam 2 and the vertical seam 3. Stripes matching the teeth 11 can be obtained on the sealant surface layer.

[0046] The cross-sections of the movable block 10, the first movable groove 15, and the second movable groove 20 are all rectangular.

[0047] A slider 23 is provided in the first movable groove 15. The slider 23 is connected to a hexagonal socket head cap screw 24 by a bearing. The hexagonal socket head cap screw 24 passes through the bottom of the movable block 10 and is threadedly connected to the movable block 10. The hexagonal socket head cap screw 24 passes through the handle 21 and is rotatably connected to the handle 21. The bottom of the hexagonal socket head cap screw 24 is set in the groove 22. When the bottom of the hexagonal socket head cap screw 24 is rotated using an Allen wrench, the hexagonal socket head cap screw 24 rotates forward, causing the slider 23 to move upward in the first movable groove 15. Conversely, the slider 23 moves downward in the first movable groove 15. The length of the transparent limiting plate 17 protruding from the seam sealing plate 9 is adjusted, so that the seam sealing thickness of the sealant 4 can be adjusted according to the concave texture lines 6 and protruding texture lines 7 on the surface of the terracotta board 1.

[0048] The semi-open joint construction method for sealant on terracotta panel curtain walls includes the following steps:

[0049] Step 1: Assemble the clay slab 1 template according to its thickness.

[0050] Specifically, there are six sets of terracotta panels 1, arranged in three rows and two columns. Adjacent sets of terracotta panels 1 are fixedly connected by connectors 8 to form a whole.

[0051] Step 2: Determine the depth of the semi-open sealant 4 and the protruding texture line 7, as well as the width of the horizontal seam 2 and the vertical seam 3. Fill the horizontal seam 2 and the vertical seam 3 to form the semi-open sealant surface layer.

[0052] Specifically, such as Figure 2 , Figure 5 and Figure 6 As shown, the depth of the semi-open sealant 4 and the protruding textured lines 7, as well as the width of the horizontal joint 2 and the vertical joint 3, are determined. Foam strips 5 are filled into the horizontal joint 2 and the vertical joint 3 respectively, and then sealant 4 is injected to form a semi-open sealant surface layer. This improves the sealing performance of the terracotta panel curtain wall, while facilitating subsequent joint sealing and reducing light penetration.

[0053] It should be noted that, while ensuring the sealing effect, the distance between the sealant layer and the clay plate 1 should be increased as much as possible to reduce the angle of subsequent light penetration; at the same time, when injecting sealant 4, it is important to remember that the amount of sealant 4 used should not be too much, and it can be injected in multiple times.

[0054] Step 3: Make the seam sealing tool.

[0055] Specifically, the process of making a seam sealing tool includes the following steps:

[0056] Step 3 - (a): Make a seam closing plate 9 according to the width of the horizontal seam 2 and the vertical seam 3, so that the width of the seam closing plate 9 is consistent with the width of the horizontal seam 2 and the vertical seam 3, and make teeth 11 on the top of the seam closing plate 9.

[0057] Step 3-(II): Connect the seam sealing plate 9 to the movable block 10 as a whole using fasteners 14.

[0058] Step 3-(III): Based on the required depth of the semi-open sealant 4 and the protruding texture line 7, attach the top of the transparent limiting plate 17 to the protruding texture line 7. Use an Allen wrench to rotate the bottom of the Allen bolt rod 24 to adjust the protruding length of the sealing plate 9 so that the depth of the semi-open sealant 4 and the protruding texture line 7 after the sealing plate 9 is closed meets the requirements.

[0059] Step 4: Perform the seam sealing work.

[0060] Specifically, the seam-sealing plate 9 on the seam-sealing tool is vertically inserted into the horizontal seam 2 and the vertical seam 3. The top of the transparent limiting plate 17 is attached to the protruding texture line 7. The teeth 11 of the seam-sealing plate 9 are adjusted to be parallel to the direction of the horizontal seam 2 and the vertical seam 3. The seam-sealing tool is slid on the clay plate 1 by the handle 21, that is, the seam-sealing plate 9 is slid in the horizontal seam 2 and the vertical seam 3, so that stripes matching the teeth 11 are obtained on the sealant surface layer.

[0061] The principle of semi-open joint construction of terracotta panel curtain wall sealant:

[0062] The principle behind the reduction in light reflection intensity when light enters the horizontal seam 2 is as follows: Figure 2 , Figure 9 and Figure 10 As shown, when exposed to natural light, due to the depth of the semi-open sealant 4 and the protruding textured lines 7, most of the inclined incident light rays 26 are blocked by the terracotta panel 1, preventing most of the light from directly entering the sealant surface layer, resulting in a smaller incident angle 25. When the partially inclined incident light rays 26 enter the horizontal seam 2 and reach the sealant surface layer, they are divided into two parts. One part is absorbed by the sealant 4 through refraction, and the other part is reflected at a 90° angle (optical law) to the terracotta panel 1 of the horizontal seam 2, becoming reflected light rays 27, which are reflected out from the terracotta panel 1. The brightness of the reflected light rays 27 is the same as that of the terracotta panel 1.

[0063] The principle behind the reduction in light reflection intensity when light enters the vertical seam 3 is as follows: Figure 5 , Figure 6 , Figure 8 , Figure 11 , Figure 12 and Figure 13 As shown, this is consistent with the principle of reduced reflection intensity when light enters the horizontal seam 2; however, the angle of incidence 25 of the light at the recessed texture line 6 of the vertical seam 3 is relatively large. It mainly utilizes the stripes on the sealant surface layer that match the teeth 11 to reflect and refract the incident light 26 multiple times, weakening the incident light 26 and obtaining the multiple reflected and refracted light 28; the angle of incidence 25 of the light at the protruding texture line 7 of the vertical seam 3 is relatively small, and the light entering the sealant surface layer is weaker, which can directly reflect the original ceramic red color.

[0064] This solves the problem of the incident light 26 affecting the reflectivity of the sealant 4 and improves the overall aesthetics of the terracotta panel curtain wall.
