Description

Technical Field

[0001] The utility model belongs to the technical field of building decoration, and in particular relates to a curtain wall closing edge sealing waterproof structure. Background Art

[0002] Curtain wall refers to the non-load-bearing exterior wall enclosure of a building. It is usually composed of a frame and multiple curtain wall panels installed on the frame, and the multiple curtain wall panels are fixed to the frame by locking parts. The locking parts are usually set at the edge sealing of the curtain wall panels, and the curtain wall is usually exposed to the outdoors, which makes the waterproof performance here particularly important. In order to improve the waterproof performance, seals are usually installed at the joints. However, the seals will age with the increase of use time, and gaps will appear due to the weakening of elastic performance, which in turn affects the waterproof performance.

[0003] For example, Chinese patent application number (CN202110387387.0) discloses a waterproof sealing structure for a building curtain wall, which includes a frame and a glass wall panel installed on the frame. A sealing rubber block is arranged between the frame and the glass wall, and is adjusted by a tightening component. It can solve the gap caused by the weakening of elastic performance due to aging and ensure waterproof performance. However, the application requires manual adjustment of the tightening component, which is time-consuming and labor-intensive and needs to be improved. Utility Model Content

[0004] The purpose of this utility model is to solve the above-mentioned technical problems and provide a curtain wall edge sealing waterproof structure, which improves the waterproof performance between the frame and the curtain wall panel and can automatically adjust after the seal has aged and a gap is generated.

[0005] In view of this, the utility model provides a curtain wall edge sealing waterproof structure, comprising:

[0006] A frame, connected to a locking member, and used to mount curtain wall panels forming the curtain wall on the exterior wall of the building;

[0007] Sealing parts are installed between the locking parts and the curtain wall panels, and between the curtain wall panels and the frame;

[0008] The anti-loosening structure is installed between the frame and the locking piece and is used to automatically prevent the seal from loosening.

[0009] In the above technical solution, further, the locking member includes:

[0010] A pressure plate, which is installed on the end surface of the curtain wall panel and is used to fix the curtain wall panel;

[0011] Bolts: A circular hole for the bolts to pass through is coaxially opened on the pressure plate, and the bolts pass through the pressure plate and are threadedly connected to the frame;

[0012] Wherein, a thickened portion for threaded connection with a bolt is provided on the frame.

[0013] In the above technical solution, further, the sealing element includes:

[0014] The first sealing strip is installed between the frame and the curtain wall panel and connected to the surface of the frame;

[0015] The second sealing strip is installed between the pressure plate and the curtain wall panel;

[0016] The sealing ring is sleeved on the bolt and is located between the bolt head and the pressure plate.

[0017] In the above technical solution, further:

[0018] One side of the second sealing strip located at the bottom end of the curtain wall panel is bent toward one side of the curtain wall panel to form a first extension portion;

[0019] The sealing ring extends into the circular hole to form a second extension portion;

[0020] The second extending portion is located between the cylindrical portion and the head of the bolt.

[0021] In the above technical solution, further, the anti-loosening structure includes:

[0022] The pulling part is sleeved on the bolt and is slidably connected to the bolt;

[0023] The pushing portion is sleeved on the bolt and is slidably connected to the bolt and is located between the pulling portion and the bolt head;

[0024] The driving part is connected to the bottom of the curtain wall panel and is inserted between the pulling part and the pushing part when the curtain wall panel moves downward, so as to cause the pulling part and the pushing part to move away from each other;

[0025] Wherein, the first extension portion is located between the bottom end of the curtain wall panel and the top end of the pushing portion.

[0026] In the above technical solution, further:

[0027] The pushing portion is provided with a cylindrical portion extending into the circular hole.

[0028] In the above technical solution, further:

[0029] The pulling part has a first inclined surface on one side close to the driving part, the pushing part has a second inclined surface on one side close to the driving part, and the driving part has a third inclined surface adapted to the first inclined surface and a fourth inclined surface adapted to the second inclined surface on both sides.

[0030] The beneficial effects of the utility model are:

[0031] 1. Automatically adjust through the anti-loosening structure to ensure the waterproof sealing effect, avoid the influence of gaps caused by aging of seals and weakening of elastic performance, which may cause the waterproof sealing performance between the frame and curtain wall panels to decrease. Automatically prevent the seals from loosening, eliminate the influence of gaps, and extend and ensure the waterproof sealing effect.

[0032] 2. When the seal ages and its elastic performance weakens to produce a gap, the curtain wall panel will gradually sink and move, and at the same time, the driving part will be pushed to be inserted between the pulling part and the pushing part. In this way, the curtain wall panel and the pushing part, as well as the pushing part and the bolt head, are close to each other and squeeze the first extension part of the second sealing strip and the second extension part of the sealing ring, thereby ensuring the squeezing of the seal, ensuring the waterproof sealing effect, and automatically adjusting, effectively extending the service life.

[0033] 3. By using the first extension part and the second extension part as the key parts of the secondary waterproof seal, compared with the second sealing strip and the sealing ring, they are never exposed to the environment and are less susceptible to rain erosion. Therefore, the service life of the seal can be effectively extended and the waterproof sealing effect can be extended and guaranteed. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] The following will be combined with the accompanying drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of this application.

[0039] Example 1:

[0040] This embodiment provides a curtain wall edge sealing waterproof structure, including:

[0041] A frame 1 is connected to a locking member 2 and is used to install curtain wall panels 3 forming a curtain wall on the exterior wall of a building;

[0042] The sealing member 4 is installed between the locking member 2 and the curtain wall panel 3 and between the curtain wall panel 3 and the frame 1;

[0043] The anti-loosening structure 5 is installed between the frame 1 and the locking member 2 and is used to automatically prevent the sealing member 4 from loosening.

[0044] It can be seen from this embodiment that the anti-loosening structure 5 is automatically adjusted to ensure the waterproof sealing effect, avoid the influence of the gap caused by the aging of the seal 4 and the weakening of the elastic performance, and cause the waterproof sealing performance between the frame 1 and the curtain wall panel 3 to decrease, automatically prevent the seal 4 from loosening, eliminate the influence of the gap, and extend and ensure the waterproof sealing effect.

[0045] Example 2:

[0046] This embodiment provides a curtain wall edge sealing waterproof structure, which, in addition to the technical solutions of the above embodiments, also has the following technical features: the locking member 2 includes:

[0047] The pressing plate 20 is installed on the end surface of the curtain wall panel 3 and is used to fix the curtain wall panel 3;

[0048] Bolt 21, a circular hole 22 for the bolt 21 to pass through is coaxially opened on the pressing plate 20, and the bolt 21 passes through the pressing plate 20 and is threadedly connected to the frame 1;

[0049] The frame 1 is provided with a thickened portion 10 for threaded connection with the bolt 21;

[0050] At the same time, the thickened portion 10 and the frame 1 are integrally formed, and the frame 1 can be a profile structure.

[0051] It can be seen from this embodiment that by connecting the bolts 21 to the frame 1 and fixing the curtain wall panel 3 by compressing the pressure plate 20, the installation convenience of the curtain wall panel 3 is improved, and the connection strength between the frame 1 and the bolts 21 is increased by the thickened portion 10, thereby ensuring the installation stability of the curtain wall panel 3.

[0052] Example 3:

[0053] This embodiment provides a curtain wall edge sealing waterproof structure, which, in addition to the technical solutions of the above embodiments, also has the following technical features: the sealing member 4 includes:

[0054] The first sealing strip 40 is installed between the frame 1 and the curtain wall panel 3 and is connected to the surface of the frame 1;

[0055] The second sealing strip 41 is installed between the pressing plate 20 and the curtain wall panel 3;

[0056] The sealing ring 42 is mounted on the bolt 21 and is located between the head of the bolt 21 and the pressure plate 20;

[0057] The first sealing strip 40 , the second sealing strip 41 and the sealing ring 42 may all be made of rubber material, and the first sealing strip 40 may be fixedly connected to the frame 1 , specifically by bonding.

[0058] It can be seen from this embodiment that the provision of the first sealing strip 40, the second sealing strip 41 and the sealing ring 42 can effectively ensure the waterproof sealing performance of the curtain wall edge sealing, avoid erosion caused by rainwater infiltration, and extend the service life.

[0059] Example 4:

[0060] This embodiment provides a curtain wall edge sealing waterproof structure, which, in addition to the technical solutions of the above embodiments, also has the following technical features:

[0061] One side of the second sealing strip 41 located at the bottom end of the curtain wall panel 3 is bent toward one side of the curtain wall panel 3 to form a first extension portion 43;

[0062] The sealing ring 42 extends into the circular hole 22 to form a second extension portion 44

[0063] The first extension portion 43 and the second sealing strip 41 are integrated into one structure, while the second extension portion 44 and the sealing ring 42 are integrated into one structure.

[0064] It can be seen from the present embodiment that the first extension portion 43 is formed by bending the bottom end of the second sealing strip 41 toward one side of the curtain wall panel 3. Then, when the sealing member 4 ages and its elastic performance weakens, the fastening spacing between the locking member 2 and the frame 1 remains unchanged, which easily causes a gap to be generated between the frame 1, the curtain wall panel 3 and the pressure plate 20, causing the curtain wall panel 3 to move downward. Therefore, the sealing performance between the pressure plate 20 and the curtain wall panel 3 can be ensured by the first extension portion 43, and the sealing ring 42 extends into the circular hole 22 to form the second extension portion 44, which can improve the sealing performance between the bolt 21 and the circular hole 22 of the pressure plate 20 and improve the waterproof performance.

[0065] Example 5:

[0066] This embodiment provides a curtain wall edge sealing waterproof structure. In addition to the technical solutions of the above embodiments, it also has the following technical features. The anti-loosening structure 5 includes:

[0067] The pulling portion 50 is sleeved on the bolt 21 and is slidably connected to the bolt 21 and extends toward one side of the pressing plate 20 to form a connecting portion 51 fixedly connected to the pressing plate 20;

[0068] The pushing portion 52 is sleeved on the bolt 21 and is slidably connected to the bolt 21 and is located between the pulling portion 50 and the head of the bolt 21;

[0069] The driving portion 53 is connected to the bottom of the curtain wall panel 3 and is inserted between the pulling portion 50 and the pushing portion 52 when the curtain wall panel 3 moves downward, so as to cause the pulling portion 50 and the pushing portion 52 to move away from each other;

[0070] The first extension portion 43 is located between the bottom end of the curtain wall panel 3 and the top end of the pushing portion 52;

[0071] At the same time, the connecting portion 51 and the pulling portion 50 adopt an integrated structure, and the connecting portion 51 and the pressing plate 20 can be welded;

[0072] The distance that the curtain wall panel 3 can move downward is smaller than the dimension between the top end of the curtain wall panel 3 and the frame 1 and the pressing plate 20 to prevent the top end of the curtain wall panel 3 from falling off and causing it to fall. Therefore, the curtain wall panel 3 is only supported to move within a small range, and it needs to be repaired later, such as replacing the seal 4, to ensure the waterproof sealing effect of the curtain wall panel 3.

[0073] It can be seen from the present embodiment that when the curtain wall panel 3 gradually sinks and moves, the driving portion 53 is pushed and inserted between the pulling portion 50 and the pushing portion 52, and thereby the curtain wall panel 3 and the pushing portion 52 are brought close to each other and squeeze the first extension portion 43 of the second sealing strip 41, thereby ensuring a waterproof sealing effect, and the pushing portion 52 will squeeze the second extension portion 44 to ensure the waterproof sealing performance at the circular hole 22 of the pressing plate 20. Therefore, it can be ensured that the connection between the pressing plate 20 and the curtain wall panel 3 exposed to the environment can improve the waterproof sealing performance, and automatically adjust, saving time and effort.

[0074] Example 6:

[0075] This embodiment provides a curtain wall edge sealing waterproof structure, which, in addition to the technical solutions of the above embodiments, also has the following technical features:

[0076] The pushing portion 52 is provided with a cylindrical portion 54 extending into the circular hole 22;

[0077] The second extension portion 44 is located between the cylindrical portion 54 and the head of the bolt 21;

[0078] At the same time, the cylindrical portion 54 and the pushing portion 52 may be formed into an integrated structure.

[0079] It can be seen from this embodiment that the provision of the cylindrical portion 54 ensures that the pushing portion 52 can effectively squeeze the second extension portion 44 after being pushed, ensuring waterproof sealing performance, and its extension into the circular hole 22 can effectively improve the stability of the pushing portion 52.

[0080] Example 7:

[0081] This embodiment provides a curtain wall edge sealing waterproof structure, which, in addition to the technical solutions of the above embodiments, also has the following technical features:

[0082] The pulling portion 50 has a first inclined surface 55 on its side close to the driving portion 53 , the pushing portion 52 has a second inclined surface 56 on its side close to the driving portion 53 , and the driving portion 53 has a third inclined surface 57 and a fourth inclined surface 58 on both sides thereof that match the first inclined surface 55 and the second inclined surface 56 .

[0083] It can be seen from this embodiment that by setting the above-mentioned inclined surface, the driving part 53 can be inserted smoothly between the pulling part 50 and the pushing part 52 to avoid jamming, ensure the anti-loosening effect of the anti-loosening structure 5, ensure the waterproof sealing effect, and effectively extend the service life.
