Description

A splicing structure of assembled curtain wall

Technical Field

The present application relates to the field of curtain walls, and in particular to a splicing structure of an assembled curtain wall.

Background Art

Curtain wall is the outer wall of a building. It is non-load-bearing and is hung up like a curtain, so it is also called "curtain wall". It is a decorative wall commonly used in modern large and high-rise buildings. It is composed of wall panels and a supporting structure system, and can have a certain displacement ability relative to the main structure or the ability to withstand a certain deformation itself.

During the assembly process of the curtain wall, in order to achieve the purpose of waterproofing, sealant is often filled in the joints of adjacent curtain wall bodies.

With respect to the above-mentioned related technologies, the inventors believe that after a certain period of use, the caulking sealant at the joints of the curtain wall is corroded by the external environment and is prone to failure or falling off. The slight displacement between adjacent wall panels is also prone to causing the caulking sealant to fail or fall off. The joints of the curtain wall have the defect of poor waterproof sealing.

Summary of the invention

In order to improve the waterproof sealing performance of the joints of curtain wall bodies, the present application provides a joint structure of an assembled curtain wall body.

The present application provides a splicing structure of an assembled curtain wall body adopts the following technical solution:

A splicing structure of an assembled curtain wall comprises two walls, wherein opposite ends of the two walls are provided with connectors, the two connectors are plugged together, and a plug-in seam with multiple bends is formed between the two connectors, the plug-in seam extends from the outer side of the wall to the inner side of the wall, a plurality of seals for sealing the plug-in seam are provided in the plug-in seam, and the setting height of the seals distributed in the wall is higher than the setting height of the seals distributed at both sides of the wall.

By adopting the above technical scheme, multiple bent joints and multiple seals form a structural waterproof system with good sealing and waterproof effects. When the outer seal fails due to corrosion, the joint can still rely on the second sealing and waterproof barrier for sealing and waterproofing. Multiple seals are arranged at different heights. When a certain height plane of the splicing structure is subjected to force, the seals in the plane are likely to be damaged, but the seals at other height positions can still form a sealing and waterproof structure that can work reliably. In addition, the height of the seals arranged inside the wall is higher than the height of the seals arranged on both sides of the wall, so that rainwater penetrating into the joint is not easy to penetrate upward and pass through the higher seals, thereby improving the sealing and waterproofing ability of the structural waterproof system.

Preferably, the two connectors are respectively configured as a male plug and a female plug, the male plug is provided with a connector strip and baffles located on both sides of the connector strip, the female plug is provided with a main slot and sub-slots located on both sides of the main slot, the connector strip is plugged into the main slot, and the baffle is plugged into the sub-slot.

By adopting the above technical solution, the plug-in cooperation between the plug-in strip and the main slot, and the plug-in cooperation between the baffle and the auxiliary slot form a plug-in seam with multiple bends between the male plug and the female plug, which has a good sealing and waterproof effect, and the male plug and the female plug limit each other in the lateral direction, which is conducive to improving the strength of the splicing structure.

Preferably, the seal includes an external elastic seal and an internal elastic seal, the external elastic seal is arranged at both ends of the joint and is located between the ends of the two walls, one side of the internal elastic seal is embedded in the side wall of the main slot, and the other side is sealed with the side wall of the plug-in strip, the two plug-in parts have a cavity in the vertical direction and a gap in the horizontal direction, and the plug-in strip is slidably arranged in the main slot.

By adopting the above technical solution, the external elastic seal is located in the vertical gap between the two walls, and the internal elastic seal is located in the horizontal gap between the two walls, which allows the two adjacent walls to have a certain deformation and displacement space in both the vertical and horizontal directions. When the wall expands and contracts, the seal can deform adaptively and always maintain a sealed state. When in harsh environments such as typhoons and earthquakes, the elastic seal can also buffer the vibration and displacement of the wall in all directions, which has the function of ensuring the stability and safety of the building structure. By adopting the above technical solution, the internal elastic seal embedded in the side wall of the main slot has good connection stability in the plug-in seam, reducing the probability of failure of the internal elastic seal due to separation from the two side walls, and increasing the service life of the internal elastic seal, thereby improving the stability of the structural waterproof system.

Preferably, wall panels are provided on both sides of the wall body, a steel keel is fixedly connected between the two wall panels, and the connector is fixedly connected to the steel keel.

By adopting the above technical scheme, steel keels are used as the main load-bearing components of the wall, and are used in conjunction with connectors made of aluminum alloy. Different materials are scientifically combined to give full play to their respective performance advantages. The use of steel keels reduces the manufacturing cost of the wall and improves the overall structural strength of the wall. The size of the panel of a single wall can be increased, and the joint seams of the entire curtain wall can be reduced, which is beneficial to the sealing and waterproofing of the entire curtain wall. In addition, the wall with a large panel size can also improve the efficiency of processing, assembly and on-site hoisting.

Preferably, a reinforcing folded edge is integrally provided on a side of the connector close to the outdoors, and the reinforcing folded edge is located on a side of the steel keel close to the outdoors and is fixedly connected to the steel keel.

By adopting the above technical solution, the setting of the reinforced folded edge increases the path length for external rainwater to enter between the steel keel and the connector, which has a waterproof effect. In addition, the setting of the reinforced folded edge increases the installation stability of the connector on the steel keel.

Preferably, a sealing strip is provided between the reinforcing folded edge and the wall panel, and one end of the sealing strip close to the plug-in seam is pressed against the external elastic sealing member.

By adopting the above technical solution, the sealing strip has a sealing and waterproof effect, which prevents external rainwater from penetrating into the wall along the gap between the reinforced folded edge and the wall panel.

Preferably, the connector is fixedly connected to the steel keel via a fastener, an elastic pad is provided between the connector and the steel keel, and the fastener is fixedly connected to the steel keel after passing through the elastic pad.

By adopting the above technical solution, elastic pads are provided at the connection between the connector and the steel keel. When the elastic pads are squeezed, they will passively deform to block small gaps, thereby reducing the probability of external rainwater penetrating from the fasteners and corroding the inside of the wall.

Preferably, a heat-insulating layer is provided between the two wall panels, and the heat-insulating layer is located on a side of the steel keel away from the connector.

By adopting the above technical solution, the thermal insulation layer has the function of thermal insulation, reducing the influence of the external environment on the indoor temperature.

In summary, the present application includes at least one of the following beneficial technical effects:

1. The multi-bend plug-in seams and multiple seals form a structural waterproof system with good sealing and waterproofing effects. When the outer seal fails due to corrosion, the plug-in seams can still rely on the second sealing and waterproof barrier for sealing and waterproofing. In addition, the height of the seals set inside the wall is higher than the height of the seals set on both sides of the wall, so that rainwater that penetrates into the plug-in seams is not easy to penetrate upward and pass through the seals at higher positions, thereby improving the sealing and waterproofing ability of the structural waterproof system;

2. The external elastic seal is located in the vertical gap between the two walls, and the internal elastic seal is located in the horizontal gap between the two walls. This allows the two adjacent walls to have a certain amount of deformation and displacement space in the vertical and horizontal directions. When the wall expands and contracts due to heat, the seal can deform adaptively and always maintain a sealed state. When in harsh environments such as typhoons and earthquakes, the elastic seal can also buffer the vibration and displacement of the wall in all directions, which plays a role in ensuring the stability and safety of the building structure;

3. Steel keels are used as the main load-bearing components of the wall, and are used in conjunction with connectors made of aluminum alloy. Different materials are scientifically combined to give full play to their respective performance advantages. The use of steel keels reduces the manufacturing cost of the wall and improves the overall structural strength of the wall.

DETAILED DESCRIPTION

The present application is further described in detail below in conjunction with Figures 1-2.

An embodiment of the present application discloses a splicing structure of an assembled curtain wall.

Referring to Figure 1, the splicing structure of the assembled curtain wall includes two walls arranged in the same plane, and the ends of the walls are provided with connectors 1. The opposite ends of the two walls are respectively provided with a male plug 11 and a female plug 12, which are plugged and matched with the male plug 11 and the female plug 12, and a plug seam 13 with multiple bends is formed between the two. The plug seam 13 extends from the side of the wall close to the outdoors to the side of the wall close to the indoors, and the plug seam 13 with multiple bends forms a sealing structure with good sealing and waterproofing effect.

2 , the male plug 11 includes a first bottom plate 111, which is flush with the end of the wall. A plug strip 112 is provided in the middle of the first bottom plate 111, and baffles 113 are provided on both sides of the plug strip 112. The baffles 113 are provided close to the side of the first bottom plate 111 and are fixedly connected to the first bottom plate 111. The plug strip 112 and the baffle 113 are both located on the side of the first bottom plate 111 away from the wall. In order to facilitate production and improve the sealing and waterproofing ability of the male plug 11, the first bottom plate 111, the plug strip 112 and the baffle 113 are integrally formed.

Correspondingly, the female plug 12 includes a second bottom plate 121, and four plugging teeth 122 are arranged on the same side of the second bottom plate 121. The four plugging teeth 122 are evenly spaced along the width direction of the second bottom plate 121 to form three plugging slots. The opening of the plugging slot is flush with the end of the wall, the plugging slot near the middle of the second bottom plate 121 is set as the main slot 123, and the plugging slots near the two sides of the second bottom plate 121 are set as the auxiliary slots 124.

1 and 2, the plug strip 112 is plugged into the main slot 123, the baffle 113 is plugged into the auxiliary slot 124, and the baffle 113 is arranged close to the side wall of the auxiliary slot 124. The end of the plug strip 112 is chamfered, and the ends of the two baffles 113 are inclined toward the side close to each other, so as to facilitate the plugging and matching of the male plug 11 and the female plug 12.

Both ends of the plug seam 13 are provided with external elastic seals 21, and the external elastic seals 21 are located between the ends of the two walls, and are used to seal the two ends of the plug seam 13. In the embodiment of the present application, the external elastic seal 21 includes a foam rod 211 and a silicone sealant 212. The foam rod 211 is arranged between the ends of the two walls, and has a buffering and vibration isolation effect. The silicone sealant 212 is arranged on the outside of the foam rod 211, and is used for sealing and waterproofing.

1 and 2, internal elastic seals 22 are embedded on both side walls of the main slot 123, and the side of the internal elastic seal 22 away from the side wall of the main slot 123 is pressed against the side wall of the plug strip 112, which has a sealing and waterproofing effect. The way the internal elastic seal 22 is embedded improves the connection stability of the internal elastic seal 22 on the side wall of the main slot 123, reduces the probability of the internal elastic seal 22 falling off due to loose installation, and reduces the occurrence of situations that affect the sealing and waterproofing ability of the plug seam 13.

The setting height of the internal elastic seal 22 is higher than the setting height of the external elastic seal 21. When a certain height plane of the wall is subjected to force, the seal 2 in the plane may be damaged. The seal 2 is set at different heights to improve the ability of the structural waterproof system to resist plane damage. When the seal 2 in a certain height plane is damaged, the seals 2 at other height planes can still serve as a good sealing and waterproof barrier, so that the plug-in seam 13 still has a certain sealing and waterproof ability. In addition, the position of the internal elastic seal 22 is higher than the external elastic seal 21. When the external elastic seal 21 close to the outdoor side fails due to corrosion, it is difficult for rainwater entering the plug-in seam 13 to penetrate upward and pass through the internal elastic seal 22, which effectively improves the sealing and waterproof ability of the plug-in seam 13.

Referring to Fig. 1 and Fig. 2, the external elastic seal 21 is clamped between the ends of the two walls in the vertical direction, and a cavity is left between the end of the plug strip 112 and the bottom of the main slot 123, and the internal elastic seal 22 is clamped between the side wall of the main slot 123 and the side wall of the plug strip 112. The two adjacent walls have a certain deformation and displacement space in the vertical and horizontal directions. In addition, the male plug 11 and the female plug 12 can slide relative to each other, which makes the two adjacent walls have a certain displacement space in three directions in the space. When the wall expands and contracts with heat, the seal 2 can deform adaptively and always maintain a sealed state. When in a harsh environment such as a typhoon or earthquake, the elastic seal 2 can also buffer the vibration and displacement of the wall in all directions, which has the function of ensuring the stability and safety of the building structure.

The plug connector 1 is made of aluminum alloy, and the plug strip 112 is hollow. The plug connector 1 made of aluminum alloy has a certain plasticity, and can still retain a certain sealing and waterproofing ability after the plug connector 1 is deformed. The hollow plug strip 112 further improves the plasticity of the plug connector 1. The plug connector 1 made of aluminum alloy is not easy to rust, which reduces the probability of the plug connector 1 being damaged due to rust and losing its waterproofing ability.

Referring to Fig. 1, wall panels 3 are provided on both sides of the connector 1, and a steel keel 4 is fixedly connected between the two wall panels 3. The steel keel 4 is located on the side of the connector 1 close to the wall. The steel keel 4 is arranged in a rectangular tubular shape as a whole. The side of the steel keel 4 close to the room is fixedly connected to the wall panel 3 by self-tapping countersunk screws, and the side of the steel keel 4 close to the outside is provided with an angle steel connector 41. One angle plate of the angle steel connector 41 is welded to the side wall of the steel keel 4 away from the connector 1, and the other angle plate is fixedly connected to the wall panel 3 by bolts, so as to realize the stable installation of the steel keel 4 in the wall.

After the angle steel connector 41 is fixedly connected to the wall panel 3 by bolts, the nut on the bolt is welded to the end of the bolt to improve the installation stability of the angle steel connector 41 on the wall panel 3, and the holes opened on the wall panel 3 due to the bolt connection are filled with glass fiber cement to reduce the probability of rainwater penetrating into the inside of the wall panel 3 from the bolt connection.

1 , a steel keel 4 is used as the main load-bearing member of the wall, and is used in conjunction with a connector 1 made of aluminum alloy. Different materials are scientifically combined to give full play to their respective performance advantages. The use of the steel keel 4 reduces the manufacturing cost of the wall and improves the overall structural strength of the wall. The size of the panel of a single wall can be increased, and the joint seams of the entire curtain wall can be reduced, which is beneficial to the sealing and waterproofing of the entire curtain wall. In addition, the wall with a large panel size can also improve the efficiency of processing, assembly and on-site hoisting.

The side of the connector 1 close to the outside is integrally provided with a reinforcing folded edge 14, and the reinforcing folded edge 14 is located on the side of the steel keel 4 close to the outside. The connector 1 is fixedly connected to the adjacent two side walls of the steel keel 4 by screws, which improves the installation stability of the connector 1 on the steel keel 4. The reinforcing folded edge 14 is located on the side of the steel keel 4 close to the outside, which increases the path length of external rainwater entering between the steel keel 4 and the connector 1, and has a waterproof effect.

Referring to Figure 1, an elastic pad 5 is arranged between the connector 1 and the steel keel 4. The screws used to connect the connector 1 and the steel keel 4 all pass through the elastic pad 5. After being squeezed, the elastic pad 5 will be passively deformed to block the tiny gap, thereby reducing the probability of external rainwater penetrating from the screws and corroding the inside of the wall.

A sealing strip 6 is provided on the side of the reinforcement fold 14 close to the outside, and one end of the sealing strip 6 close to the plug-in seam 13 is pressed against the external elastic seal 21. In the embodiment of the present application, the sealing strip 6 is provided as a double-sided elastic positioning tape, which is conducive to the fixing of the sealing strip 6 between the reinforcement fold 14 and the wall panel 3. The sealing strip 6 has a sealing and waterproof effect, which prevents external rainwater from penetrating into the wall along the gap between the reinforcement fold 14 and the wall panel 3.

An insulation layer 7 is also provided between the two wall panels 3. In the embodiment of the present application, the insulation layer 7 is made of rock wool. The insulation layer 7 has the function of thermal insulation and can reduce the influence of the external environment on the indoor temperature.

The implementation principle of the splicing structure of an assembled curtain wall in the embodiment of the present application is:

The multi-bend joint seams 13 and the multiple seals 2 arranged on the path form a structural waterproof system with good sealing and waterproofing effect. When the outer seal 2 is corroded and fails, the joint seams 13 can still rely on the second sealing and waterproof barrier for sealing and waterproofing.

The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
