Description

Technical Field

[0001] The invention belongs to the technical field of building curtain walls, and particularly relates to an assembled special-shaped ceramic stick curtain wall installation structure and an installation method. Background Art

[0002] In the field of modern architecture, curtain wall, as the external protective structure of the building, not only undertakes functional roles such as windproof, waterproof, and heat insulation, but also has a decisive influence on the shaping of the building's appearance. Ceramic sticks are made of natural clay as the main raw material, with the characteristics of bright and gentle color, affinity, and good durability. The natural texture of ceramic sticks and their eternal clay color have greatly aroused the interest of owners and architectural designers, and are widely used.

[0003] Problems with existing technologies: With the development of the construction industry, special-shaped ceramic rod curtain walls have been widely used in the field of building decoration due to their unique appearance and excellent performance. Most of the existing installation structures use traditional connectors to fix the ceramic rods to the curtain wall frame. The traditional design of ceramic rods uses back bolts to punch holes to install special-shaped ceramic rods. Each ceramic rod needs to be punched and bolted, which requires high processing accuracy. In addition, the ceramic rods are easy to break, resulting in large installation losses and high labor costs. Summary of the Invention

[0004] The purpose of the present invention is to provide an assembled special-shaped ceramic stick curtain wall installation structure and installation method, which can reduce the processing loss of ceramic sticks by changing the original connection method between the rear opening of the special-shaped ceramic sticks and the ceramic stick hangers, thereby improving the quality of the finished product and the curtain wall installation accuracy.

[0005] The technical solutions adopted by the present invention are as follows: A prefabricated special-shaped ceramic stick curtain wall installation structure includes special-shaped ceramic sticks and a support plate. The special-shaped ceramic sticks include special-shaped ceramic stick 1 and special-shaped ceramic stick 2. Through holes are opened at the ends of the special-shaped ceramic stick 1 and special-shaped ceramic stick 2. A metal tube 1 is detachably assembled near the end of the support plate. The metal tube 1 is inserted into the inside of the through hole. A limiting assembly for positioning the special-shaped ceramic sticks is fixedly installed inside the metal tube 1. When disassembling, the special-shaped ceramic sticks and the metal tube 1 are pushed in the horizontal direction, and the limiting assembly is separated from the support plate.

[0006] One side of the top of the support plate is provided with a through groove 1 at equal intervals, and the front and rear ends of the center of the top of the support plate are both provided with a through groove 2. A through hole for installing the metal tube 1 is provided on the side of the support plate away from the through groove 1. The metal tube 2 is embedded in the inner wall of the one side of the support plate corresponding to the through hole, and a rubber strip is embedded in the inside of the through hole and on the outer surface of the metal tube 1.

[0007] Screw rods are slidably arranged inside the two second strip grooves, and baffles are fixedly installed on the tops of the two screw rods.

[0008] A second ring plate is integrally fixedly installed inside the bottom end of the first metal tube and close to the second metal tube. The second ring plate is fixedly assembled with the limiting component.

[0009] The limit assembly includes a connecting plate fixedly mounted on the bottom of the second ring plate, a limit rod is slidably provided through the center of the connecting plate, a groove plate is fixedly mounted on the bottom end of the limit rod, a top plate is fixedly mounted on the bottom of the groove plate, a top block is fixedly mounted on the bottom of the top plate, and a spring is sleeved on the outer surface of the limit rod and located between the connecting plate and the groove plate.

[0010] A connecting rod is provided inside the bottom end of the metal tube 1 for opposite rotation, and a fixing plate 1 and a fixing plate 2 are fixedly installed integrally on the outer surface of the connecting rod in sequence. A ring plate 1 is fixedly installed integrally and equidistantly inside the metal tube 2, and the fixing plate 1 and the fixing plate 2 are perpendicular to each other to the connecting rod.

[0011] The two fixing plates 2 are both provided with notches on one side away from each other, and the fixing plates 2 and the ring plate 1 form a detachable clamping relationship.

[0012] A clamping block is integrally fixed to one end of each of the two fixing plates close to each other, and clamping slots are provided on both sides of the bottom of the top plate, and the clamping block and the clamping slot form a detachable clamping relationship.

[0013] A method for installing an assembled special-shaped ceramic rod curtain wall is used to install the assembled special-shaped ceramic rod curtain wall installation structure as described above, comprising the following steps: Step 1: Connect, adjust and fix the main keel to the rear embedded plate, and then fix the transverse keel on the surface of the main keel; Step 2: After deepening the design of the ceramic stick model through BIM technology, the original ceramic stick back bolt punching installation method is changed to the ceramic stick unified production and processing reserved through-holes; Step 3: Fix the limit assembly to the bottom of the metal tube one, and align the metal tube one with the top of the metal tube two so that the fixing plate two is inserted into the inside of the metal tube two. The inclined surface of the bottom of the fixing plate two contacts the ring plate one inside the metal tube two and causes the connecting rod to rotate at a small angle. When the bottom end of the fixing plate two is clamped to the bottom of the ring plate one, with the cooperation of the spring, the top block presses the fixing plate one so that the fixing plate two and the ring plate one are tightly clamped; Step 4: Place the rubber strip into the through hole of the ceramic stick, and insert one end of the metal tube 1 of the support plate assembled with the metal tube 1 into the through hole; Step 5: Align the groove of the support plate with the special-shaped ceramic stick installed with the horizontal keel, and fix the support plate to the horizontal keel with screws.

[0014] The technical effects achieved by the present invention are: In the present invention, after deepening the design of the ceramic stick model through BIM technology, the original ceramic stick back bolt opening and implantation of the back bolt nut and the ceramic stick pendant connection installation method is changed to a ceramic stick unified production and processing reserved hole, thereby reducing the ceramic stick processing loss and improving the ceramic stick processing accuracy.

[0015] The present invention assembles a metal tube into a hanger through a limiting component and a support plate, and installs a ceramic stick on the assembled hanger on site. By assembling the assembled hanger and the special-shaped ceramic stick half-unit, the special-shaped ceramic stick can be quickly installed, and the support plate is fixed to the keel installed in advance by screws, which reduces the construction difficulty and meets the needs of construction in complex and harsh environments such as long-term heavy rainfall, heavy snowfall, and strong wind, and realizes fast construction. At the same time, it improves the quality of the finished product and the installation accuracy of the curtain wall, reduces the frequency and time of high-altitude operations, reduces construction safety hazards, and reduces environmental pollution such as noise.

[0016] The present invention clamps and fixes the circumference of the special-shaped ceramic stick by means of a screw rod sliding inside the second strip groove and a baffle plate on its top. When a single special-shaped ceramic stick is damaged, the baffle plate is removed by twisting the nut at the bottom of the screw rod. At this time, the special-shaped ceramic stick is pushed, and the metal tube one is away from the metal tube two, so that the connecting rod rotates, and as the metal tube one moves, the fixing plate one rotates and engages with the slot. At this time, a part of the fixing plate one is horizontal to the bottom of the metal tube one, so that the metal tube one and the metal tube two can be separated, and the damaged special-shaped ceramic stick can be quickly disassembled, thereby improving the replacement efficiency of the damaged ceramic stick and reducing the difficulty of maintenance.

DETAILED DESCRIPTION

[0019] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is described in detail below with reference to the following examples. It should be understood that the following text is only used to describe one or more specific embodiments of the present invention and does not strictly limit the scope of protection of the present invention.

[0020] like Figures 1-8 As shown, an assembled special-shaped ceramic stick curtain wall installation structure and installation method include special-shaped ceramic sticks and a support plate 3. The special-shaped ceramic sticks include special-shaped ceramic stick 1 and special-shaped ceramic stick 2. The ends of special-shaped ceramic stick 1 and special-shaped ceramic stick 2 are provided with through holes 7. A metal tube 5 is detachably assembled near the end of the support plate 3. The metal tube 5 is inserted into the inside of the through hole 7. A limiting component 6 for positioning the special-shaped ceramic sticks is fixedly installed inside the metal tube 5. When disassembling, the special-shaped ceramic sticks and the metal tube 5 are pushed horizontally, and the limiting component 6 is separated from the support plate 3.

[0021] Refer to the attached Figure 2 、 Figure 5 and Figure 6 , one side of the top of the support plate 3 is penetrated by a strip groove 31 at equal intervals, and the front and rear ends of the center of the top of the support plate 3 are penetrated by a strip groove 2 32, and the side of the support plate 3 away from the strip groove 31 is provided with a through hole for installing the metal tube 5, and a metal tube 2 36 is embedded in the inner wall of the one side of the support plate 3 and the corresponding through hole, and a rubber strip 4 is embedded in the inside of the through hole 7 and on the outer surface of the metal tube 1 5. A connecting rod 52 is provided inside the bottom end of the metal tube 1 5 in opposite rotation, and a fixing plate 1 53 and a fixing plate 2 54 are fixedly installed in an integral manner on the outer surface of the connecting rod 52 in sequence, and a ring plate 1 37 is fixedly installed in an integral manner at equal intervals inside the metal tube 2 36.

[0022] Furthermore, after deepening the design of the ceramic stick model through BIM technology, the original ceramic stick back bolt hole and the back bolt nut were implanted into the ceramic stick pendant connection installation method, which was changed to two through holes 7 reserved in the unified production and processing of the ceramic stick. The two through holes 7 facilitate installation with metal pendants, while avoiding damage to special-shaped ceramic sticks and improving installation accuracy.

[0023] Furthermore, at this time, the limit assembly 6 is fixed to the bottom of the ring plate 2 51 inside the metal tube 1 5 by screws, and the metal tube 1 5 is placed on the top of the metal tube 2 36. When the fixing plate 2 54 is inserted into the top of the metal tube 2 36, the inclined surface at the bottom end of the fixing plate 2 54 contacts and slides with the ring plate 1 37, so that the connecting rod 52 rotates and squeezes the top block 66, so that the two fixing plates 2 54 are close to each other. When the ring plate 1 37 is placed at the notch of the fixing plate 2 54, the two sides of the bottom end of the top block 66 press the two fixing plates 1 53 again under the action of the spring 63, so that the two fixing plates 2 54 are firmly clamped with the ring plate 1 37.

[0024] Furthermore, after the metal hanger is assembled, the through hole 7 of the special-shaped ceramic stick 1 or the special-shaped ceramic stick 2 is plugged into the rubber strip 4 made of EPDM. The rubber strip 4 made of EPDM has both weather resistance and elasticity, which can cushion the special-shaped ceramic stick 1 and increase the service life of the special-shaped ceramic stick. The assembled metal tube 1 is placed in the through hole 7 inserted with the rubber strip 4 to fix the special-shaped ceramic stick. At this time, the strip groove 1 31 is placed on the pre-installed keel, and the support plate 3 is stably fixed to the keel by screws, thereby realizing the rapid installation of the ceramic stick curtain wall, reducing the installation difficulty, reducing construction noise, and improving installation efficiency and quality.

[0025] Refer to the attached Figure 6 、 Figure 7 and Figure 8 , a ring plate 2 51 is integrally fixedly installed inside the bottom end of the metal tube 1 5 and close to the metal tube 2 36. The ring plate 2 51 is fixedly assembled with the limit assembly 6. The limit assembly 6 includes a connecting plate 61 fixedly installed at the bottom of the ring plate 2 51. A limit rod 64 is slidably provided at the center of the top of the connecting plate 61. A groove plate 62 is fixedly installed at the bottom of the groove plate 62. A top plate 65 is fixedly installed at the bottom of the top plate 65. A top block 66 is integrally fixedly installed at the bottom of the top plate 65. The limit A spring 63 is sleeved on the outer surface of the rod 64 and is located between the connecting plate 61 and the groove plate 62. A notch is provided on the side of the two fixed plates 54 away from each other. The fixed plate 2 54 and the ring plate 1 37 form a detachable clamping relationship. The two fixed plates 1 53 are close to each other at one end and a clamping block 55 is fixed integrally. A clamping groove 67 is provided on both sides of the bottom of the top plate 65. The clamping block 55 and the clamping groove 67 form a detachable clamping relationship. The fixed plate 1 53 and the fixed plate 2 54 are perpendicular to the connecting rod 52.

[0026] Furthermore, when the metal tube 1 5 is installed at the top and bottom ends of the support plate 3, the limit assembly 6 is fixed to the bottom of the ring plate 2 51 at the bottom end of the metal tube 1 5 by screws. When the metal tube 1 5 is inserted into the metal tube 2 36, the inclined surface at the bottom end of the fixing plate 2 54 contacts and slides with the ring plate 1 37, causing the connecting rod 52 to rotate and squeeze the top block 66, so that the two fixing plates 2 54 are close to each other. When the ring plate 1 37 is placed at the notch of the fixing plate 2 54, the two sides of the bottom end of the top block 66 press the two fixing plates 1 53 again under the action of the spring 63, so that the two fixing plates 2 54 are firmly clamped with the ring plate 1 37.

[0027] Furthermore, when replacing a damaged special-shaped pottery stick, first screw the nut at the bottom end of the screw 33 to remove the two baffles 34. At this time, the special-shaped pottery stick is pushed to the front end, so that the inner wall of the top end of the metal tube 36 contacts the fixed plate 2 54, and the connecting rod 52 is rotated. At this time, the fixed plate 1 53 contacts the bottom end of the top block 66 and squeezes the top block 66 and the top plate 65 to move toward the top. When the block 55 at one end of the fixed plate 1 53 rotates to the slot 67, the block 55 is stuck in the inside of the slot 67, and the connection is made under the action of the spring 63. The plate 61 and the groove plate 62 are away from each other, fixing the fixing plate 1 53, and then fixing the angle of the connecting rod 52. The fixing plate 1 53 and the fixing plate 2 54 are perpendicular to each other at 90 degrees. When the block 55 of the fixing plate 1 53 is engaged in the slot 67, the fixing plate 2 54 is horizontal to the bottom of the metal tube 1 5, and then the special-shaped ceramic stick is moved in the opposite direction again, and the above operation is repeated, so that the metal tube 1 5 and the metal tube 2 36 are only in contact with the end faces, and then the special-shaped ceramic stick can be quickly disassembled and replaced, reducing the difficulty of maintenance and improving work efficiency. Furthermore, when replacing a new special-shaped ceramic stick, the block 55 at one end of the fixing plate 53 can be disengaged from the card slot 67 by inserting a rod to press the top block 66 and manually rotating the connecting rod 52, so that the metal tube 1 5 and the metal tube 2 36 can be connected again, thereby improving the replacement efficiency.

[0028] Refer to the attached Figure 3 Screws 33 are slidably provided inside the two grooves 32, baffles 34 are fixedly installed on the tops of the two screws 33, rubber pads 35 are fixedly installed on the inner sides of the two baffles 34, and nuts are screwed on the bottom ends of the two screws 33.

[0029] Furthermore, when the special-shaped ceramic stick is fixed to the outer surface of the metal tube 5, the position and angle of the screw 33 are flexibly adjusted through the groove 2 32 to adapt to special-shaped ceramic sticks of different sizes and models. When the position of the screw 33 is determined, the position and angle of the baffle 34 are fixed by tightening the nut at the bottom end of the screw 33. On the one hand, the special-shaped ceramic stick is clamped from both sides, and on the other hand, the position of the special-shaped ceramic stick is limited to avoid a large impact force hitting the ceramic stick. When the fixing plate 2 54 on one side of the bottom end of the metal tube 5 moves and no longer engages with the ring plate 1 37 inside the metal tube 2 36, the rearward movement of the special-shaped ceramic stick is restricted.

[0030] Furthermore, when subjected to a large impact force, the fixing plate 2 54 close to the side of the keel contacts the inside of the metal tube 2 36, limiting the direction of the deviation of the special-shaped ceramic stick, and limiting the moving position of the special-shaped ceramic stick by cooperating with the support plates 3 at the top and bottom ends of the special-shaped ceramic stick, thereby preventing the special-shaped ceramic stick from falling and further improving safety. On the one hand, the rubber pad 35 has a buffering property, preventing excessive tightening force from causing damage to the surface of the special-shaped ceramic stick, and on the other hand, increases the friction of the baffle 34, thereby improving the stability of the special-shaped ceramic stick.

[0031] like Figures 1-8 As shown, a method for installing an assembled special-shaped ceramic stick curtain wall, which is used for the special-shaped ceramic stick curtain wall installation structure in this embodiment, includes the following steps: Step 1: Connect the main keel to the rear embedded plate of the building with bolts, adjust and fix it according to the horizontal data, and then fix the horizontal keel on the surface of the main keel with screws.

[0032] Step 2: After deepening the design of the ceramic stick model through BIM technology, the original ceramic stick back bolt punching installation method is changed to the ceramic stick unified production and processing reserved through hole 7 in the production factory in advance, realizing the ceramic stick curtain wall assembly installation, improving the installation efficiency, and avoiding quality problems and cost losses caused by on-site processing. When the bottom end of the fixing plate 2 54 is clamped at the bottom of the ring plate 1 37 , with the cooperation of the spring 63 , the inclined surface of the bottom end of the top block 66 presses the two fixing plates 1 53 so that the fixing plates 2 54 are moved away from each other and are tightly clamped with the ring plate 1 37 .

[0033] Step 4: Place the rubber strip 4 into the through hole 7 of the ceramic stick, insert one end of the metal tube 5 of the support plate 3 assembled with the metal tube 5 into the through hole 7 and locate it on the inner wall of the rubber strip 4, and then assemble and fix the special-shaped ceramic stick; Step 5: Align the groove 31 of the support plate 3 with the installed special-shaped pottery stick with the horizontal keel, and fix the support plate 3 on the horizontal keel with screws, thereby achieving rapid installation of the special-shaped pottery stick.

[0034] The foregoing is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications are also within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained herein shall, unless otherwise specified or limited, be implemented in accordance with conventional means in the art.
