Description

Technical Field

[0001] This utility model relates to curtain wall structures, and more particularly to a unitized window curtain wall structure. Background Technology

[0002] Conventional unitized window curtain wall structures require bolts to fix the columns and covers of the unitized curtain wall. Since bolts are external components, while columns, covers and other components are internal components, in order to provide installation space for the bolts, certain groove structures must be formed on the columns, covers and other components. This groove structure is prone to water accumulation and seepage, which can lead to corrosion or rust of the curtain wall structure.

[0003] To better illustrate this, we can use specific examples to understand it. For instance, referring to the structural understanding disclosed in patents CN112538924A and CN218233923U, the space formed by the bolt installation is usually on the same side as the unit glass frame and faces the outdoors, making it easy for rainwater to seep in. Utility Model Content

The core is fitted into the second mating groove, and the outer periphery of the core is interference-fitted with the first mating groove.

[0007] The beneficial effects of this utility model are as follows: Compared with the prior art, which uses bolts to fix the column and the body, requiring drilling holes at corresponding positions to install bolts, resulting in gaps at the bolt holes and the clearance structure at the bolt holes, reducing the sealing performance of the curtain wall and causing problems such as air leakage and water leakage, and in severe cases, even threatening the structural safety of the entire building, in this embodiment, the sleeve is fitted into the second mating groove of the column mating section, and the outer periphery of the sleeve is interference-fitted with the first mating groove of the body, so that the column and the body form a tight whole through the sleeve, and the various components constrain each other and share the force, eliminating the bolt structure. The interference fit ensures a tight fit between the sleeve and the first mating groove, and the absence of bolts can avoid the problem of water seepage.

[0008] Preferably, the first mating groove has a protrusion that abuts against the side of the sleeve core near the column.

[0009] Preferably, the core is a cylinder, and the outer surface of the cylinder is a high-friction pair surface.

[0010] Preferably, the sleeve core includes a first sleeve body and a second sleeve body, the first sleeve body being closer to the post than the second sleeve body, and the diameter of the first sleeve body being smaller than that of the second sleeve body, so that the first sleeve body and the second sleeve body form a stepped surface; the protrusion abuts against one side of the second sleeve body facing the post.

[0028] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0029] See Figures 1-2 This utility model provides a technical solution:

[0030] A unit window curtain wall structure includes a main body 100, a column 200, and a core 300.

[0031] The body 100 extends a first engaging portion 110 and a second engaging portion 120 along its circumference. The engaging space defined between the first engaging portion 110 and the second engaging portion 120 is used to secure the glass. That is, the first engaging portion 110 and the second engaging portion 120 can be interference-fitted with the glass to be clamped to achieve clamping. The body 100 is constructed with a first mating groove 11 along the axial direction.

[0032] For example, refer to Figure 1 and Figure 2As shown, the first engaging part 110 is an aluminum alloy buckle, and the second engaging part 120 is a unitized glass sub-frame. During installation, the glass is first placed within the engaging space defined by the aluminum alloy buckle and the unitized glass sub-frame. During this process, the aluminum alloy buckle and the unitized glass sub-frame undergo elastic deformation due to the glass's size being slightly larger than the initial distance between them. The aluminum alloy buckle typically possesses good elasticity and strength, generating a certain reaction force when pressed by the glass, tightly fitting against one edge of the glass. The unitized glass sub-frame also possesses corresponding elastic deformation capabilities, adaptively adjusting according to the shape and size of the glass, maintaining close contact with the other edge of the glass. This interference fit generates pressure evenly distributed across the edge area of ​​the glass, thus firmly securing the glass within the engaging space, effectively preventing loosening or displacement during subsequent use, and ensuring the overall stability and safety of the unitized window curtain wall structure.

[0033] The column 200 can be constructed of aluminum alloy material, such as... Figure 1 and Figure 2 The device shown includes a fixed section 210 and a mating section 220. The fixed section 210 is fixed to the wall, and the mating section 220 is embedded in the first mating groove 11. A second mating groove 221 is provided on the periphery of the mating section 220. The sleeve 300 is fitted in the second mating groove 221, and the outer periphery of the sleeve 300 is interference-fitted with the first mating groove 11.

[0034] In this embodiment, compared to the existing technology where bolts are used to fix the column 200 and the body 100, which requires drilling holes at corresponding locations to install bolts, resulting in gaps at the bolt holes and the clearance structures at the bolt holes, reducing the sealing performance of the curtain wall and causing problems such as air leakage and water leakage, and in severe cases, even threatening the structural safety of the entire building, the sleeve 300 is fitted into the second mating groove 221 of the mating section 220 of the column 200. At the same time, the outer periphery of the sleeve 300 is interference-fitted with the first mating groove 11 of the body 100, so that the column 200 and the body 100 form a tight whole through the sleeve 300. The various components constrain each other and share the force, eliminating the bolt structure. The interference fit ensures that the sleeve 300 and the first mating groove 11 fit tightly, and the absence of bolts can avoid the problem of water seepage.

[0035] Furthermore, to improve the overall structural stability, a protrusion 130 is constructed within the first mating groove 11. The protrusion 130 engages with the side of the sleeve 300 closest to the column 200, thereby limiting the sleeve 300 through the protrusion 130, ensuring a stable fit between the body 100 and the sleeve 300. During installation, the sleeve 300 and column 200 are sequentially fitted onto the body 100.

[0036] In detail, the diameter of the fixing section 210 of the column 200 is larger than the diameter of the mating section 220, and a first airtight pad 400 is provided in the area where the fixing section 210 faces the body 100 and abuts against the body 100.

[0037] For example, refer to Figure 1 and Figure 2 As shown, the aluminum alloy buckle has a small groove on the side near the column 200. The small groove holds the first airtight gasket 400 in place to form a seal between the two, thereby preventing liquid from entering the gap between them.

[0038] In this example, the body 100 includes a left segment 12 and a right segment 13. The left segment 12 and the right segment 13 are joined together to define the first mating groove 11. A second airtight gasket 500 is provided in the area where the first mating groove 11 abuts against the end face of the mating segment 220. Similarly, the second airtight gasket 500 is also suitable for forming a seal, which will not be described in detail.

[0039] Furthermore, since this embodiment does not require bolts to be installed along the axial direction of the column 200, a partition seal 600 can be provided between the left side section 12 and the right side section 13. The partition seal 600 seals the fitting gap between the left side section 12 and the right side section 13. This ensures that rainwater and other liquids will not seep in through the fitting gap between the left side section 12 and the right side section 13, making all internal components of the entire unit curtain wall structure sealed relative to the outside, preventing corrosion, rust, or other damage due to liquid infiltration.

[0040] Next, we will illustrate this with two specific examples.

[0041] First embodiment, reference Figure 1 The sleeve 300 is a column, and the outer surface of the column is a high-friction surface, for example, the outer surface of the column is constructed as a rubber layer. In this way, the interference fit of the sleeve 300 can not only provide a relative fixing effect between the column 200 and the sleeve 300, but also provide a certain sealing effect.

[0042] exist Figure 1 In the example, the protrusion 130 is an annular protrusion 130A on the inner wall of the first mating groove 11. The annular protrusion 130A is located at the edge of the aluminum alloy buckle cover near the column 200. The aforementioned annular part is formed by splicing two annular parts, namely, the left side section 12 and the right side section 13 are matched and matched to form an annular part. During installation, both the annular protrusion 130A and the rubber on the outer periphery of the sleeve 300 have a certain elasticity, so the sleeve 300 can be pushed into the first mounting groove with force.

[0043] Second embodiment, reference Figure 2As shown, the sleeve 300 of the left segment 12 is the same as in the first embodiment. The sleeve 300 of the right segment 13 includes a first sleeve body 131B and a second sleeve body 132B. The first sleeve body 131B is closer to the column 200 than the second sleeve body 132B. The diameter of the first sleeve body 131B is smaller than that of the second sleeve body 132B, so that the first sleeve body 131B and the second sleeve body 132B form a stepped surface. The protrusion 130 abuts against the side of the second sleeve body 132B facing the column 200.

[0044] Specifically, the protrusion 130 is a snap-fit ​​block 130B. One side of the snap-fit ​​block 130B is secured to the body 100, and the other side extends to the side of the second sleeve 132B facing the column 200. The snap-fit ​​block 130B engages with the second sleeve 132B through its periphery. Thus, the contact area between the protrusion 130 and the second sleeve 132B along the axis of the column 200 is larger than that of the annular protrusion 130A in the first embodiment, resulting in a better fixing effect.

[0045] In this example, the snap-fit ​​block 130B also includes a card 1311B and a bolt portion 1312B. A third mating groove 111 is constructed on the inner wall of the first mating groove 11. The card 1311B is snapped into the third mating groove 111. The stud of the bolt is disposed through the card 1311B and the body 100. The bolt head is adapted to push against the second sleeve 132B.

[0046] During installation, first, fix the card 1311B in the third mating groove 111, then place the core into the first mating groove 11, and fix the bolt to the card 1311B so that the bolt head abuts against the step surface. Next, attach the column 200 to the right side section 13. Since the left side section 12 has not yet been installed, there will be no installation interference when the column 200 mates with the right side section 13. Finally, install the left side section 12 and insert it into the annular core described in the first embodiment to complete the installation.

It should be understood that this utility model is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or related technologies or knowledge.
