Technical Field

[0001] The present invention belongs to the technical field of curtain walls, and more particularly, relates to a unitized curtain wall closing and waterproofing device. Background Art

[0002] In the building curtain wall decoration industry, glass curtain walls are widely used due to their excellent appearance and plasticity. Among them, the unitized curtain wall system has the characteristics of prefabricated buildings, which can effectively improve curtain wall performance, shorten construction period, and improve curtain wall quality. It is currently the most popular curtain wall system.

[0003] At the same time, the construction of unitized curtain walls has strict requirements on the process. The joints of adjacent unit panels need to be installed with water-proof rubber, horizontal sliders, and weather-resistant sealant. However, during the curtain wall construction process, due to the presence of vertical transportation equipment such as construction elevators (or tower cranes), the curtain wall cannot be installed continuously with the large surface at this location. The curtain wall unit panels can only be installed after the construction elevator (tower crane) is dismantled.

[0004] Due to the aforementioned situation that the curtain wall cannot be installed continuously, it is easy to lead to the inability to guarantee the construction quality of the water-proof rubber, horizontal slider (used to connect the gap between two adjacent curtain walls, usually glue is applied on the horizontal slider (connecting plate) to prevent water leakage in the gap.), and sealant at the closing position (the closing position refers to the curtain wall already installed above one of the curtain walls, and the top of the other curtain wall is open and the curtain wall is not installed yet. Therefore, the quality of the glue at the gap of the curtain wall that has not yet been installed on the top can be guaranteed, while the quality of the glue at the gap of the curtain wall that has been installed on the top is difficult to guarantee.), there is a risk of system leakage, and subsequent detection and maintenance are difficult. Summary of the Invention

[0005] The purpose of the present invention is to provide a unitized curtain wall sealing waterproof device to solve the problem in the prior art that when the curtain wall cannot be installed continuously, the construction quality of the sealant at the sealing position is difficult to ensure and there is a hidden danger of water leakage.

[0006] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is as follows: a unitized curtain wall closing and waterproofing device is provided, comprising a connecting plate and a connecting rubber strip, wherein a gap is formed at the connection of the tops of two unitized curtain walls connected side by side at the closing position, the connecting plate is used to be arranged at the connection to seal the gap, and is used to be connected to the connection of the tops of the two unitized curtain walls connected side by side; the connecting rubber strip is arranged between the top surface of the unitized curtain wall and the connecting plate, the top surface of the connecting rubber strip is in contact with the connecting plate, and one end of the connecting rubber strip extends between the two unitized curtain walls installed up and down; the other end of the connecting rubber strip overlaps the top surface of the other unitized curtain wall connected side by side, and the top surface of this end is open.

[0007] Furthermore, the length of the connecting rubber strip is greater than the length of the connecting plate.

[0008] Furthermore, the connecting rubber strip is a flexible rubber strip.

[0009] Preferably, the unitized curtain wall sealing and waterproofing device further comprises a waterstop plate, which is arranged between two unitized curtain walls installed vertically, and the end of the connecting rubber strip extending into the two unitized curtain walls is located between the waterstop plate and the gap.

[0010] Preferably, the water stop plate is an aluminum alloy plate.

[0011] Furthermore, the unitized curtain wall includes curtain wall glass and a male crossbeam arranged on the top of the curtain wall glass. The male crossbeam is connected to the curtain wall glass in an L shape. The male crossbeam is formed with a groove, and the connecting plate, the connecting rubber strip and the water stop plate are arranged in the groove.

[0012] Furthermore, the male crossbeam includes a first section forming the groove and a second section connecting the curtain wall glass, the second section is located between the curtain wall glass and the first section, and the connecting rubber strip includes a first rubber strip arranged in the groove and a second rubber strip arranged on the second section.

[0013] Furthermore, the groove is a U-shaped groove, and the male crossbeam includes a base plate and a first side plate and a second side plate arranged on both sides of the base plate. The top of the first side plate and the second side plate are provided with a limiting plate for limiting the connecting plate and the first rubber strip.

[0030] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0031] Please also refer to Figure 1 and Figure 2 , the unit curtain wall 3 closing and waterproofing device provided by the embodiment of the present invention is now described. The unit curtain wall 3 closing and waterproofing device includes a connecting plate 1 and a connecting adhesive strip 5. Among them, there is a gap 4 at the connection between the tops of the two unit curtain walls 3 connected side by side. In order to ensure the sealing of the curtain wall, this gap 4 needs to be sealed. In order to prevent water leakage, sealant is generally applied on the connecting plate 1. The method of applying glue is very easy to implement for the unit curtain walls 3 that are not in the closing position 2, because there is no interference from another unit curtain wall 3 above the gap 4, and the quality of the gluing can be detected and guaranteed. Therefore, for the gap 4 that is not in the closing position 2, it is only necessary to use a connecting plate 1, overlap the two ends of the connecting plate 1 on the two unit curtain walls 3 connected side by side, and then apply glue to seal the gap 4. As for the two side-by-side unitized curtain walls 3 at the closing position 2, another unitized curtain wall 3 has been installed on the top of one of the unitized curtain walls 3. Therefore, the quality of gluing can be guaranteed for half of the gap 4 there. However, it is difficult to ensure the quality of gluing for the portion where the connecting plate 1 is located between the upper and lower unitized curtain walls 3. The connecting plate 1 needs to be inserted from the gap between the upper and lower unitized curtain walls 3. If the traditional installation method is still used (after gluing the connecting plate 1, inserting the connecting plate 1 into the upper and lower unitized curtain walls 3 along the gap), water leakage is likely to occur. Therefore, sealant is applied in advance on the top of the unitized curtain wall 3, and then the connecting strip 5 is installed in the gap between the upper and lower unitized curtain walls 3 to ensure the installation sealing of the connecting strip 5. Subsequently, the connecting plate 1 is installed in the gap between the upper and lower unitized curtain walls 3, and the connecting strip 5 is located at the bottom of the connecting plate 1. This greatly improves the waterproof quality of the gap 4 at the closing position 2 and reduces the risk of water leakage.

[0032] Compared with the prior art, the unitized curtain wall 3 closing waterproof device provided by the present invention has a new connecting rubber strip 5 at the closing position 2, and uses the connecting rubber strip 5 and the connecting plate 1 to simultaneously block the gap 4. First, the connecting rubber strip 5 is installed along the gap between the upper and lower unitized curtain walls 3, and then the connecting plate 1 is installed along the gap. The connecting rubber strip 5 is used to first ensure the connection sealing of the upper and lower unitized curtain walls 3, and then the connecting plate 1 is installed. After the connecting plate 1 and the connecting rubber strip 5 are connected, the sealing is further improved. This avoids the problem of difficulty in ensuring the quality of the gluing when directly gluing the connecting plate 1 and then installing it, reduces the possibility of water leakage, and reduces the hidden dangers of water leakage.

[0033] Preferably, see Figure 2The length of the connecting rubber strip 5 is greater than that of the connecting plate 1, and the connecting rubber strip 5 is a flexible rubber strip. The length of the connecting rubber strip 5 is designed to be longer than that of the connecting plate 1, which can improve the waterproof performance and avoid the need to glue the connecting rubber strip 5 and the connecting plate 1 at the edge. It is very inconvenient to glue the connecting rubber strip 5 and the connecting plate 1 after they are inserted into the gap between the upper and lower unit curtain walls 3. After one end of the connecting rubber strip 5 is inserted into the gap, the other end is exposed. In curtain wall operations, installation is often done from bottom to top, that is, the unit curtain wall 3 located above is installed vertically downward on the top of the unit curtain wall 3 below. Therefore, a flexible strip is selected for the connecting strip 5. After the connecting strip 5 is installed along the gap, the connecting strip 5 can be bent upward. After the other unit curtain wall 3 at the closing position is installed side by side with the unit curtain wall 3, the connecting strip 5 is restored to its original shape. The exposed end of the connecting strip 5 is then overlapped on the newly installed unit curtain wall 3, reducing interference with the curtain wall operation.

[0034] Further, see Figure 2 、 Figure 3 and Figure 5In this embodiment, the unitized curtain wall 3 includes curtain wall glass 31, a male crossbeam 32, and a female crossbeam 33, wherein the male crossbeam 32 is arranged at the top of the curtain wall glass 31, and the female crossbeam 33 is arranged at the bottom of the glass curtain wall. The male crossbeam 32 is used to connect to the female crossbeam 33 of the unitized curtain wall 3 on top of it. The shape of the connection between the male crossbeam 32 and the glass curtain wall is L-shaped, and the male crossbeam 32 is formed with a groove 7, and the connecting plate 1 and the connecting rubber strip 5 are both installed in the groove 7. In addition, a water stop plate 6 for detecting water leakage is also provided in the groove 7, wherein the water stop plate 6 is arranged between the upper and lower unitized curtain walls 3 at the closing position 2. As mentioned above, one end of the connecting rubber strip 5 extends into the gap between the upper and lower unitized curtain walls 3 at the closing position 2, and a gap 4 is formed between the two side-by-side unitized curtain walls 3. The end of the connecting rubber strip 5 extending into the gap is located between the water stop plate 6 and the gap 4. The waterstop plate 6 blocks the direction of the groove 7 toward the other end, so water can be poured into the groove 7. Since the quality of the glue applied to the groove 7 is guaranteed, if a leak occurs, it can only occur in the gap 4 where the connecting rubber strip 5 is installed at the closing position 2. The staff can immediately stop the curtain wall operation and reinstall the connecting rubber strip 5 and the connecting plate 1 at that location. In addition, after the entire building is completed and put into use, if a leak occurs on this floor, from a bird's-eye view, due to the presence of the waterstop plate 6, the leak is likely to occur between the two waterstop plates 6. The two waterstop plates 6 are due to the shape of the closing position 2, with one waterstop plate 6 on each side. Since the unit curtain wall 3 outside the closing position 2 does not need to be installed with waterstop plates 6 and connecting rubber strips 5, if a leak occurs on this floor, the part sandwiched between the two waterstop plates 6 is the most likely place for leaks to occur. The subsequent staff at the edge can locate the leaking location and facilitate repairs, saving repair time and improving repair efficiency. In this embodiment, the material of the water stop plate 6 is aluminum alloy. Of course, in other embodiments, a specific material can be selected according to actual conditions and needs.

[0035] Specifically, see Figure 3 The male crossbeam 32 includes a first section 321 and a second section 322. The second section 322 is located between the curtain wall glass 31 and the first section 321, and the first section 321 forms the male crossbeam 32 mentioned above. Since a gap 4 is formed between the two side-by-side unitized curtain walls 3, and this gap 4 exists on both the first section 321 and the second section 322, the corresponding connecting rubber strips 5 also include a first rubber strip 51 and a second rubber strip 52. The first rubber strip 51 connects the first sections 321 of the two male crossbeams 32, and the second rubber strip 52 connects the second sections 322 of the two male crossbeams 32. The connecting plate 1 connects the first sections 321 of the two male crossbeams 32, and the connecting plate 1 is not required on the second sections 322. Therefore, the length of the second rubber strip 52 is designed to be shorter than that of the first rubber strip 51.

[0036] Specifically, see Figures 3 to 6The groove 7 formed by the aforementioned male crossbeam 32 is a U-shaped groove. The male crossbeam 32 includes a base plate, a first side plate 323, and a second side plate 324 disposed thereon. The base plate, the first side plate 323, and the second side plate 324 form the aforementioned U-shaped groove. Furthermore, a limit plate 325 is disposed on the top of the first and second side plates 323, 324. The limit plate 325 forms a limit groove with the first and second side plates 323, 324. During installation, the tops of the connecting plate 1 and the two side plates of the connecting rubber strip 5 are both inserted into the limit groove, facilitating the insertion of the connecting rubber strip 5 and the connecting plate 1 along the U-shaped groove.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
